REPOSAL® winding machine releases special winding machine for frequency divider inductors

              REPOSAL® winding machine releases special winding machine for frequency divider inductors

            In daily life, have you ever noticed more than one horn on your car? And more expensive cars have more horns. According to normal people's thinking, the car as long as there is a horn can emit sound signals on the line, more horn is why? The reason is very simple, for example, the turn signal and the warning horn are completely different, the sound frequency is different, and the sound range of the speakers used for high and low is naturally different. A single speaker cannot play a full frequency sound, and a sound may require a combination of multiple channels of sound to achieve a clear cue.

                                                              

            Therefore, in order to make each speaker emit audio suitable for it, it is necessary to use a tool such as a frequency divider. In simple words, the frequency divider is a filter circuit composed of a capacitor and a frequency divider inductor coil wound by the frequency divider winding machine. The capacitor filters the low frequency to the tweeter, and the frequency divider inductor is wound by the frequency divider winding machine to filter the high bottom to the low frequency to the woofer, so as to distinguish the sound signals in different frequency bands in a sound. It has different sound frequency channels, high frequency sound channels can only pass high frequency sound, middle and low frequency sound the same. After the sound is distinguished, the sound is amplified and played in the corresponding sound amplifier, and finally we can get the most accurate audio we want.

            Frequency dividers are divided into two categories, one is a power divider, and the other is an electronic divider.

            The power divider is set in the speaker, the power amplifier in the speaker first amplifies the sound power, and then the power divider divides it into three audio signals, high, middle and low, and finally sends it to different speakers for playback. The advantage of this power divider is that it is simple and convenient to connect and use, but its disadvantages are also obvious, that is, its power consumption is large and the parameter deviation value is large, the error of the sound frequency is large, and its error is related to the impedance of the speaker, so it is not convenient to adjust.

    Precision winding machine

      Precision winding machine For general winding machines, including CNC and automatic winding machines, only the set number of turns of enameled wire is required to be wound, and the appearance is roughly flat, but there are some special high-demand occasions , It is required that the arrangement of enameled wires must be neat without a random winding.

       

       This kind of coil has several advantages. First, the consistency of inductance is very high. Second, the enameled wire occupies less space, and the enameled wire can reach the ideal neat arrangement. Third, the energy density is high. Fourth, the high temperature resistance performance is better. , The enameled wires are in line contact, and in the case of random winding, the superimposition between the wires will have a little contact, and it is easy to break down under high temperature and high pressure.


       In order to achieve a stable and neat arrangement, in addition to the requirements for enameled wires, compared with general coil winding machines, high requirements are put forward for the electronic control, mechanism design and manufacturing accuracy of structural parts of the fine winding machine.

REPOSAL®  Winding Machine successfully overcomes the difficulty in the winding process of closed coils of fixed-length titanium plates with loops.

REPOSAL® Winding Machine successfully overcomes the difficulty in the winding process of closed coils of fixed-length titanium plates with loops.

             REPOSAL®  Winding Machine successfully overcomes the difficulty in the winding process of closed coils of fixed-length titanium plates with loops.

      These tiny looped titanium plates are shown here, small metal structures approximately 12mm long, 4mm wide and 1.5mm thick, and have a row of four circular holes through them, two of which are for The main body pulls the suture through, and the other two upper holes are used for the passage of another group of seam lines. The structure is small in size, and it is necessary to form a closed connecting loop through the structural member, and the closed connecting loop is formed by twisting the yarn fibers of the loose structure. A closed high-strength braided coil is passed through the middle, which seems simple, but its core technology is reflected in the Loop, that is, a high-strength coil, which is woven evenly, tightly, non-woven, and without joints.


        This kind of titanium plate with loops is divided into two types, fixed-length type and adjustable type, especially the fixed-length type, whose length ranges from 15mm to 60mm. It is necessary to wind this closed loop in the middle of a titanium plate with such a small volume. Coils, and because the number of colonies cannot exceed the standard, cannot be wound by hand, but must be wound by 

equipment, which is extremely difficult to process. Its structural parts are small in size, and the diameter of the holes is only 1-1.5mm. It needs to form twisted yarns under such conditions, so this product has always been processed manually by hand, and its efficiency is low and consistent. Sex is hard to guarantee.

            

Because of the small size of the structure, the diameter of the hole is only 1-1.5mm, and it needs to form twisted yarn under this condition, so this product has been processed manually, and its efficiency is low. Consistency is difficult to guarantee.

   REPOSAL® Winding Machine successfully developed this equipment according to the customer's request, completed the simultaneous formation of a closed loop (including fiber bundles with a loose structure) and passed it to the porous structural parts, and maintained the twisted structure, which greatly improved the closed loop. The winding efficiency, in addition to obtaining the incomparable consistency of pure hand-made, makes the product have the conditions for large-scale production.

 REPOSAL ® winding machine Honeycomb coil winding machine

REPOSAL ® winding machine Honeycomb coil winding machine

                  

REPOSAL® numerical control honeycomb winding machine, specially designed for honeycomb inductor coil, honeycomb coil with its small size, small distribution capacitance, and large inductance in some special occasions has irreplaceable. All of these excellent properties are due to the unique structure of the honeycomb coil,

Traditional honeycomb winding machine is to rely on a set of complex gear system to achieve the function, if you need to wind different honeycomb coils, need to manufacture and replace different gears, quite cumbersome and very low efficiency, REPOSAL® CNC honeycomb winding machine uses high-precision control system, with specific algorithms, high precision, fast speed, through different Settings can be wound different widths, different fold points, Different number of turns of honeycomb coil, let you wind honeycomb coil handy.

 

The inductance of the honeycomb coil is large, mainly because of its special structure. After it is wound, from the appearance, it is like a honeycomb, formed by the regular winding of coils to form a honeycomb, in this one honeycomb, the magnetic flux of each honeycomb is interconnected, and the magnetic flux density of these small magnets changes with the change of time and position, just like the food in a honeycomb. This distribution of magnetic flux pores makes the inductance of the honeycomb coil larger, because it has more magnet interaction, thus forming more magnetic flux, improving the permeability of the current, making the inductance increase.

At the same time, since the magnetic flux of each small magnet in the honeycomb coil is interconnected, the inductance can be increased by increasing the size of the honeycomb. The larger inductance of the honeycomb coil is due to its shape and the distribution of magnetic flux pores, rather than due to the increase in resistance.

The insulated wire wrapped around the honeycomb coil can be a single strand of enameled wire, or can be multiple strands of enameled wire or silk-covered wire.

People are usually curious about how this kind of coil is wound out, and the following is a demonstration of the CNC honeycomb coil winding machine developed by our company.

Enameled wire production process

Enameled wire production process

Enameled wire technological process: pay-off→anneal→paint→baking→cooling→take-up

1. Pay-off On a normally operating enameled machine, most of the operator's energy and physical strength are consumed in the pay-off part. The replacement of the pay-off reel makes the operator pay a lot of labor, and the joints are prone to quality problems when changing the line. An operating failure has occurred. An effective method is to pay off with large capacity.

     The key to pay off is to control the tension. When the tension is large, it will not only draw the conductor thin, make the surface of the wire lose its brightness, but also affect many properties of the enameled wire. From the appearance point of view, the enameled wire that is drawn thinner has poor gloss; from the performance point of view, the elongation, resilience, flexibility, and thermal shock of the enameled wire are all affected. If the pay-off tension is too small, the line will easily jump and cause the line to be merged and the line to touch the furnace mouth. When paying off, the most fear is that the half-turn tension is high and the half-turn tension is small. This will not only cause the wires to loosen, break, and be thinned section by section, but also cause large jumps of the wires in the oven, resulting in failures of merging and touching the wires. Pay-off tension should be even and appropriate.

     Installing a booster wheel in front of the annealing furnace is very helpful for tension control. The maximum non-extension tension of soft copper wire at room temperature is about 15kg/mm2, the maximum non-extension tension at 400℃ is about 7kg/mm2; the maximum non-extension tension at 460℃ is 4kg/mm2; the maximum non-extension tension at 500℃ The extension tension is 2kg/mm2. In the normal enameled wire coating process, the tension of the enameled wire is significantly less than the non-extension tension, which is required to be controlled at about 50%, and the pay-off tension should be controlled at about 20% of the non-extension tension.

     Now we focus on the use of the controller of the toroidal coil winding machine. The controller is very mature. It is divided into several functional areas. This one is the status area. For example, the indicator light before the standby character is on, which is standby. Status, the red light in front of the standby is on. For example, when we press Start, the running light will turn on, indicating that it is currently running. This is a status area.

      This is a numeric parameter. When we want to set the parameters of the toroidal coil winding machine, for example, the parameters such as the diameter of the outer diameter and the diameter of the enameled wire, there is still a cable angle for the ring-shaped product. From this position to this position slowly, this involves a range. We use the winding angle and the cable angle to control the cable range on the controller interface, after the specified cable angle , He went back to the line, before and after the set winding angle and line angle.

     The other is the speed. The high-speed and low-speed reference on the controller interface of the loop coil winding machine. The high-speed refers to the normal winding speed. The low-speed is the speed at the beginning and the end, and then the number of slow-down laps. Specify a specific number, such as slow speed, you need to specify a lap speed of one lap, two laps and three laps, according to your needs.

       Here is a switch parameter area, such as the direction of the winding, such as the storage ring on this toroidal coil winding machine, we can let him turn clockwise or counterclockwise, and then the direction of the cable, the cable The direction is the process of winding the product. We can also let him turn clockwise or counterclockwise. This is the direction of the cable. Whether to start automatically between different programs, this can also be set.

After the completion of the structure, the self-adhesive enameled wire process was adopted, and the self-adhesive coil winding machine was further optimized. The project was successfully completed. At the same time, some experience was summarized and shared with the public during the process.

              

      In recent years, due to self-adhesive support, self-adhesive coils do not need to be dipped in the later stage, which is convenient for industrialization. They have been widely used in deflection coils of precision instruments, combined coils in micro motors, and micro coils in sensors.

REPOSAL ® winding machine has successfully realized the coil preparation process of the frameless capillary magnetic liquid acceleration sensor

            In particular, the non-magnetic material in the magnetic liquid will be subjected to a magnetic field force in the non-uniform magnetic field, which makes many magnetic liquid acceleration sensors can be designed based on this characteristic.

            These characteristics make the magnetic liquid acceleration sensor has many advantages compared with the traditional acceleration sensor, such as no wear, high sensitivity and simple structure.

                    
                            

            However, most of the existing magnetic liquid acceleration sensors use solid mass blocks as non-magnetic substances, and use coils to detect changes in inductance under different accelerations to obtain output signals. However, its disadvantage is that it leads to complex magnetic circuit and poor sensor stability.

REPOSAL ® winding machine to overcome guidance fiber wire winding process difficulties

           Guidance communication has an excellent application prospect, but the guided fiber wire package needs to be wound long distance without defects, but because the surface of the fiber is smooth, brittle and easy to break, as well as the residual stress generated by the micro bending will make the signal attenuation, so it is more difficult to wind than other fibers, making long distance fast fiber automatic winding without defects has become a major issue.

      Precision Flexible Roche Coil Winding Machine is a special equipment for winding precision flexible Roche coils. With the actual project as the background, Xiepu successfully developed a precision flexible Rogowski coil winding machine by decomposing the flexible Rogowski coil winding process.

     The precision flexible Roche coil winding machine does not belong to the ranks of general numerical control equipment, but a special non-standard equipment. For this type of equipment, it is mainly reflected in a special purpose. Since the special purpose means that the market demand is not large, it is indispensable. For equipment manufacturers, the development of such special equipment is not favored, and cost control is very difficult.

REPOSAL® winding machine has successfully provided competitive solutions to the electron microscopy winding process

REPOSAL® winding machine has successfully provided competitive solutions to the electron microscopy winding process

           The main components of scanning electron microscope are electron optics system, signal collection and processing system, vacuum system, image processing display and recording system, power system and computer control system. The core part is the electron optical system, which is mainly composed of electron gun, electromagnetic condenser, diaphragm, scanning system, astigator, objective lens and various centering coils.

            

           Reposal® winding machine As a professional supplier of precision winding solutions, we focus on the electromagnetic condenser, objective and astigmatic, because the main components are enamoured wire windings, and the precision and consistency of the windings are highly related to the image quality of the scanning electron microscope.

          Electromagnetic lens coil.

           The electromagnetic lens is mainly used to restrain the electron beam and it can be regarded as a convex lens in optics. Because the electron beam in a rotating symmetric magnetic field will be subjected to the Lorentz force, resulting in a focusing effect. Therefore, the quality of the enamelled wire winding coil that can generate this rotationally symmetric rather than uniform magnetic field and make the electron beam focus imaging is very important.

           The enamelled wire winding coil in the magnetic lens, when the current passes through the coil, the pole shoe is magnetized, and a magnetic field is established in the heart cavity, producing a focusing effect on the electron beam. There are two kinds of enamelled wire winding in the magnetic lens, namely, the enamelled wire winding of the condenser and the enamelled wire winding of the objective lens. The lens near the electron gun is the enamelled wire winding of the condenser, while the one near the sample is the enamelled wire winding of the objective lens. General condenser is the high excitation lens enamelled wire winding, high excitation lens enamelled wire winding has many turns, a cylindrical multi-layer arrangement, requires good rotation symmetry

REPOSAL® Winding machine Optimum design of CNC winding machine for large power transformer

REPOSAL® Winding machine Optimum design of CNC winding machine for large power transformer

In the manufacture of power transformers, winding the transformer coil is a super important step, you think, the transformer coil is wound more firmly and neatly, the strength of the transformer and the ability to protect against short circuits can be greatly improved. However, most of the current transformer winding machines have to rely on manual extra sorting of the coil, the entire equipment is low in automation, and the production efficiency is not high, so the development of an excellent large transformer winding machine is a crucial thing for our company.

                                           

We have studied the main shaft technology of transformer winding machine, the relationship between compaction force and winding quality, and the control of compaction force. According to the principle and process flow of transformer winding, we put forward a whole design scheme of large transformer winding machine, including mechanical structure and electrical control. Mechanically, we simplify the complex structure of traditional transformer winders. In terms of electrical control, we ensure the stability of the motor when it starts and stops, and ensure that the winding coil is evenly tightened during the winding process. For the core parts of the transformer winding machine, spindle system and pressing device, we have calculated and selected the types and parameters. With the compaction device, we are able to provide real-time axial and radial compaction forces during the winding process of the transformer winding, which is very effective for improving the tightness of the winding.

The static analysis of the radial compaction device of the winding machine is also carried out by using finite element method, and the structure optimization is carried out according to the analysis results. We find that as the number of layers and turns of the winding increases, the required axial and radial compression forces change accordingly. By analyzing the experimental data, we find that there is a maximum value and a minimum value in the range of quality requirements, and it is the most reasonable choice to make the compression force approximately proportional to the number of layers and the number of turns.

The large transformer winding machine developed by our company has been preliminatively debugged and put into the market. After testing, the performance parameters of this transformer winding machine are in line with the design requirements, and the operation is stable and efficient. It can be wound to make a tight and regular transformer winding coil, and has been fully recognized by the market.

As a power grid equipment, power transformer converts voltage through the electromagnetic induction between the winding coils of the transformer. With the continuous development of the market, higher requirements are put forward for the manufacturing level of transformers, and the market needs more energy-saving and efficient transformers. Therefore, the optimization of the transformer manufacturing process is particularly critical. Quality and performance depend on the process equipment. The technical level of the transformer winding machine directly reflects the manufacturing level of the transformer. Therefore, accelerating the development of transformer winding machine is an important guarantee to improve the performance of transformer.

                                              

The winding coil of the transformer is the core component of the transformer and constitutes the electromagnetic induction part of the transformer. It generally includes high voltage winding and low voltage winding, respectively connected to the high voltage grid and low voltage grid. The winding of large power transformers usually adopts concentric winding, that is, the high and low voltage transformer winding coils are centrally set on the core column. The manufacture of transformer winding is the core process of transformer, and its quality plays a crucial role in the performance of transformer, affecting the appearance of transformer size, weight, mechanical properties, insulation and heat resistance and other important indicators.

In the past, the production of transformer winding coils relied on manual, and workers had to wind insulated wires manually to the winding die frame in accordance with the process requirements. Turns calculation also have to rely on manual, this old-fashioned method is inefficient, and because the worker's skills are not strong enough, the quality of the winding coil is poor, the number of turns may be miscalculated or missed, and ultimately lead to the finished winding coil performance can not be guaranteed. Later appeared semi-automatic transformer winding machine, which is driven by the motor to rotate the spindle to wind the transformer winding coil, although it improves the production efficiency, but the wiring work still has to rely on manual, only suitable for flat winding transformer winding coil winding, and winding head winding, welding and other operations must still be completed manually, so the product quality is not stable.

Later, with the emergence of TTL logic gate circuits, in the mid-1970s, with the development of CMOS technology, various types of equipment program control a large number of applications of digital integrated circuits, Western countries and Japan and other industrial powers have emerged CNC winding mechanism manufacturing industry. These CNC transformer winding machines represent the advanced level of winding mechanism manufacturing technology, especially the winding equipment produced in Japan, Italy, the United States and Germany is the leading technology.

Now the transformer winding machine as the core parts of the transformer production equipment, the market demand is very large, and the transformer manufacturing enterprises at home and abroad attach great importance to the development and application of advanced technology of transformer winding machine. Domestic transformer winding machine production enterprises are small, insufficient technical reserves, limited research and development funds, so there is still a big gap compared with foreign advanced products, the market share is low, unable to compete with foreign countries. To solve the key technical problems of transformer winding machine is the key to improve the quality of domestic winding equipment and enhance the market competitiveness. In order to meet the demand of transformer manufacturers for high quality and low price winding equipment, especially large transformer winding machine, on the basis of learning from foreign advanced experience, combined with domestic research results, the development of large transformer winding machine has important significance and practical value.

REPOSAL® winding Machine successfully overcomes the polarization grid precision winding technology

REPOSAL® winding Machine successfully overcomes the polarization grid precision winding technology

         Since these polarized wire grids, which are wound by precision winding machines, have no underlying substrate, they have the advantage that they are not affected by substrate related dispersion and absorption, and there is no beam deviation during transmission. This provides a thin, compact and versatile polarization element with a high degree of polarization over a wide transmission range.

        

         At present, because there is no professional winding machine, most of the polarization grid used in our country is imported polarization grid, and the price is expensive; However, the domestic processing method of wire grid mainly uses manual winding, which has low precision and long production cycle. At the same time, the winding machine at home and abroad is mainly used in electronic components, sensors, etc., the control variable is relatively single, and the main control mode is tight layout, even the high precision winding machine, there are few equal spacing layout for the polarization line grid, so the accuracy can not meet its needs. Therefore, it is very important for the coiler to overcome the polarization grid precision winding technology.

           Fiber optic guidance of wire-guided missile is a closed-loop guidance and control of controlled missile by bidirectional transmission of information and control signals between missile and launcher using special fiber optics.

           Fiber optic guidance belongs to the wire guidance of remote control guidance, its advantages are not only high precision, strong anti-interference ability, can be equipped with optical cable shaft, micro camera, missile launch tail will release fiber, can control the missile and obtain target information.

                  

           The winding and release technology of optical fiber is a key technology of optical fiber guidance. At present, we have not realized automatic production in the production of optical fiber winding in our country, so we rely on the winding technical personnel's proficiency very high. The cross-turns working procedure of the winding process is still mainly manual operation, low production efficiency, high error probability and low consistency.

                             

           In addition to other ways to solve the high speed release of optical fiber, an important way is to ensure the smooth release of optical fiber through optical fiber winding. Optical fiber winding technology is the requirement of the pointer to the optical fiber guided missile and the technology of winding the optical fiber on the spool. In view of the unique properties of optical fiber and the special use of optical fiber guided missile, optical fiber winding becomes a complicated technical problem. In the process of automatic winding, the technical difficulties related to the properties of optical fiber are as follows:

                                           ----------solve the problem of heat pipe coil winding process

                                           

       Flowmeter is one of the commonly used instruments in industrial production, the most common such as all kinds of water meters in life, gear water meters, electromagnetic water meters, ultrasonic water meters, etc., according to the different industry applications, chemical, petroleum, pharmaceutical, food and other industries are also widely used, can measure the volume or quality of various fluids through the pipeline in a given time. Easy to measure in each fluid automation control.

          However, in medical, aerospace, military and other fields, we may need to measure tiny fluid flows, and in microfluidic processes, micro-thermal flow meters are also necessary, which can measure very small fluid flows, thereby helping researchers control the flow of fluid in microfluidic devices and optimize device performance.

         Another example is the flow control of pure oxygen fluid in the ventilator, the flow control of the medical dosage ratio, the flow equivalent is very small, and at the same time, it requires extremely high measurement accuracy, so the thermal micro-flow meter should appear according to demand.

          The thermal micro flowmeter is mainly made of the principle of capillary heat compensation. In the thermal micrometer, the fluid passes through a small pipe, and on the outer wall of the pipe, the thermal micrometer winding machine is used to wind a very small electric heating coil, which usually uses a fine platinum resistance wire, with a diameter between 0.02 and 0.05mm. When the fluid flows through the platinum resistance heating coil, the temperature of the fluid increases slightly. At this time, another set of platinum resistance coils wound by the thermal micro-flowmeter winding machine can sense a higher resistance, and the controller converts this resistance value into a flow value.

          The diameter of the platinum resistance coil in the micrometer is very small, and the texture is fragile, and it will heat up after being energized. When the fluid passes through the capillary of the flowmeter, the flow will take away the heat of the platinum resistance coil wound by the hot micro-flowmeter winding machine, resulting in a decrease in the temperature of the platinum resistance coil. In order to keep the temperature of the platinum resistance coil stable, the micro flowmeter will provide a certain current according to the measurement needs to maintain the temperature of the hot wire at a constant operating temperature. By measuring the change in current provided to the hot wire, the mass flow rate of the fluid can be obtained.

                                 

             Thermal micro flowmeter has many advantages, the main advantage is high accuracy, can measure the flow range of small small fluid, the accuracy can usually be within 1%. Moreover, it is small in size and can be easily designed into module units for convenient arrangement. It can also directly output electrical signals, and the communication with the data collector is convenient.

However, its manufacturing difficulty is high, especially the platinum resistance heating coil, the need for hot micro-flowmeter winding machine, in a very small diameter capillary wound diameter 0.02-0.05 platinum wire, the small diameter of the platinum wire itself is more fragile, the capillary also needs to overcome the radial displacement caused by the tension of the platinum wire during the winding process, and requires orderly arrangement. The tension is stable and the resistance is consistent, so the process is extremely difficult, and the current micro-precision winding technology of this hot micro flowmeter winding machine has been supported by sensor companies in Japan, the Netherlands and Germany for a long time.

           The domestic precision winding mechanism manufacturing system from low-end to high-end, there are huge challenges, because there are shortcomings in the manufacturing equipment link, not only the problem of individual equipment such as hot micro flow meter winding machine, but the entire precision winding machine industry is lack of independent development conditions, the industry is keen to imitate foreign industry technology for a long time, and the user long-term superstition imported equipment, It is also one of the conditions for domestic winding machine enterprises to lack independent development, so the cost of domestic thermal micro-flow meters has been high.

Research and design of enamelled wire tensioning force control system for REPOSAL ®  winding machine

Research and design of enamelled wire tensioning force control system for REPOSAL ® winding machine

With the development of our society and the progress of science and technology, the demand for high frequency and high voltage special power supplies in all walks of life is increasing day by day. The main core process in the production and manufacturing of high frequency and high voltage power supplies is the winding of interlayer insulated high voltage pack coil, and the technical level of interlayer insulated high voltage pack coil winding depends on the technical level of coil winding machine. But at present, the domestic high pressure coil winding machine has a low degree of automation, poor processing quality and production efficiency, and can not realize the automatic arrangement of enameled wire and insulated tape. In addition, the tension control technology of the wire is backward, the acceleration of the transmission speed, the change of the radius and the radial runout and axial movement of the winding spindle during the winding process will lead to the sudden change of the tension force of the wire, resulting in the turn to turn row of the interlayer insulated high voltage pack coil deviating from the ideal value, and the low quality of the wound interlayer insulated high voltage pack coil. In this context, the company began to develop high pressure coil winding machine and enameled-wire tension control system, the main research content is as follows:

                                          

Firstly, the process of layer wound high pressure packet winding machine is analyzed, the mechanical structure of layer wound high pressure packet winding machine is determined, and the related concepts of tension control of enameled wire are introduced.

In view of the high requirement of motor control algorithm in the process of enameled wire winding, the multi-motor cooperative control is analyzed, and the parameters are selected by MATLAB simulation and optimization according to the actual requirements of the project, and the multi-motor cooperative control scheme of the multi-motor of the multi-motor coiler is designed. Then, taking the insulation layer rewinding system of the high pressure packet winding machine as the research object, the mechanical model of the system is analyzed dynamically.

Research and development background and characteristics of precision current transformer winding machine

Research and development background and characteristics of precision current transformer winding machine

               Research and development background and characteristics of precision current transformer winding machine

              The precision of coil in current transformer is very important, because it directly affects the accuracy of current measurement and the reliable operation of power system. The specific importance of coil accuracy is reflected in the following aspects.

              Electrical energy metering: In a power system, accurate measurement of current is the key to calculating energy consumption. If the coil in the current transformer is not accurate, it will lead to an error in the measurement of electrical energy, which can lead to a miscalculation of energy costs, with possible financial implications for both the utility and the consumer.

              Fault detection: The current transformer is used to monitor the current level to detect abnormal conditions in the power system, such as short circuit and overload. If the accuracy of the coil is not high, it may lead to false positives or neglect of potential faults, which affects the reliability of the power system.

              Overcurrent protection: Current transformers play a key role in overcurrent protection devices, detecting overcurrent events and triggering circuit breakers or other protective devices. The accuracy of the coil directly affects whether the overcurrent can be accurately detected to ensure the safety of the power system.

              Load management: The load management of a power system requires accurate measurement of current in order to make reasonable load distribution and adjustment. If the precision of the coil is not high, it may lead to unbalanced load distribution, affecting the efficiency and stability of the power system.

              Automated control: In modern power systems, automated control systems rely on accurate current measurement data for real-time adjustment and control. The precision of the coil is critical to the response speed and performance of the system.

              Waveform analysis: Current transformers are also used for power quality analysis, including harmonic analysis. The precision of the coil determines the accurate analysis of the current waveform, which helps to solve the power quality problem.

Study on the control of the speed curve of the coiling machine for precision coiling machine

Study on the control of the speed curve of the coiling machine for precision coiling machine

             Your factory is using a traditional winding machine, your wire machine structure is reasonable, high mechanical accuracy, the motor is also used a big brand of motor, but in the winding of precision coils, there will be a high defect rate, you carefully analyze before improving various factors - equipment structure, processing accuracy, tooling accuracy, skeleton accuracy, enamel wire quality, tension control, etc. But it still doesn't solve the problem. But to tell you that it's not just a hardware problem, but an algorithm problem, may surprise you. Because in your opinion, every time the spool is transferred, the spool has a corresponding response, but in fact, you may not have considered that in the winding process of the precision coil, the wire guide pin is connected at both ends of the coil, and the sudden change in speed may cause the coil to cross the line and be raised. These defects can degrade the performance of the coil.

                 

            To solve this problem, we propose an acceleration and deceleration method based on 5-segment S-curve. The algorithm uses linear acceleration or deceleration at the end and end of the line motion control to help reduce coil defects. We first verify the feasibility of the algorithm by using ADAMS software. The software simulates the motion of the precision winding coil and obtains the velocity curve and displacement curve during the motion. Later, the experimental results show that the method of adopting S-curve in the alignment speed control can reduce the coil defect by up to 50%. This shows that the 5-section S-curve motion control algorithm is a promising method to improve the precision and efficiency of the winding process of electric precision coils. By using this algorithm, coil manufacturers can reduce the risk of coil defects and improve coil performance.

            Winding machine is a special production equipment for precision winding coils. They can be divided into stator winding machine, flying fork winding machine, ring winding machine and flat winding machine according to the working mode and object. Different types of equipment are suitable for the production of different objects. For example, the stator winding machine is mainly used to produce motor stator coils, while the parallel winding machine is used to produce electromagnetic switching coils.

            Ordinary algorithm of parallel winding machine in the production of precision winding coil products, although our mechanical structure, parts processing accuracy has been done very well, but often there is a problem of low wiring accuracy. In the process of winding a line coil, there are two main movements, one is the rotating movement of the skeleton, which is called winding movement, and the other is the translation movement of the guide needle, which is called wiring movement, and wiring transport is matched with winding movement. After years of technical accumulation, we analyze that the leading role in the alignment accuracy is the alignment movement of the guide needle. Therefore, if you want to improve the alignment accuracy of the coil, you need to optimize the alignment movement of the guide pin.

            In fact, we have always believed that the winding machine is equivalent to the lathe in the electrical industry, its importance is self-evident, so for its accuracy, there have been many experts and scholars to study this.

            Some people studied the mathematical model of precise alignment based on axial pressure compensation around the axis in the process of alignment. The axial pressure was used to improve the alignment regularity of the coil, and the mathematical model was established according to the analysis of the end point of the coil alignment, which improved the alignment accuracy of the coil.

            Some people use the 5-section S-curve control algorithm and the 7-section S-curve control algorithm respectively in the research. In motion control, the 7-section S-curve is more complicated than the 5-section S-curve control. This method has achieved more results in the field of CNC machining, but it is not mature in the field of winding machine.

            The tension instability caused by the friction between the enamelled wire and the conductor nozzle during coil winding has been studied, which leads to the uneven wiring of the coil and the breakage of the enamelled wire.

            Some people have studied the low efficiency of the winding machine in the traditional winding control because of the inertia error in the process of the winding machine. Instead, the servo motion wiring and the inertia error supplement are used to improve the control efficiency of the winding machine.

            PLC control is commonly used in the winding machine wiring control system, through PLC control servo motor can realize the winding machine wiring control, both PLC control stability and high precision servo motor advantages. However, there is a sudden impact of guide pin speed in the coil alignment of parallel winding machine, so it is necessary to further optimize the change of guide pin running speed to improve product quality and the smoothness of wire alignment speed. The S-curve algorithm is a kind of smooth transition of speed in the process of motion, which is often used in machining to solve the problem of breaking the tool caused by speed impact and improve the precision of machining products. In the winding machine, the speed of the guide needle can be changed into an arc smooth transition by controlling the movement track of the guide needle, improving the alignment accuracy and product quality.

            To sum up, an algorithm based on 5-segment S-curve motion control is proposed to solve the problem of velocity shock in the process of coil alignment by analyzing the law of coil alignment. ADAMS software is used to simulate the trajectory of the guide pin to verify the feasibility of the algorithm. And the application of the example proves that the 5-section S-shaped curve can effectively solve the phenomenon of crossing and protruding in the process of winding, and improve the precision of winding.

            Coil wiring principle

            The winding method is flat winding, that is, the enameled wire moves synchronously with the guide pin and always keeps perpendicular to the skeleton during winding. The frame is driven by the winding motor with the guide needle movement, the enameled wire is wound on the skeleton, in which the guide needle is located in the wiring arrangement mechanism and the winding mechanism are two independent mechanisms. The winding mechanism is divided into three stages according to the motion process of the guide pin, namely acceleration and deceleration stage, uniform speed stage and end point return stage. The acceleration and deceleration stage can be divided into two parts: acceleration stage and deceleration stage. In the early stage of the alignment movement, the guide pin speed from zero to uniform speed belongs to the acceleration stage. At the end of the alignment movement, the process of decelerating until the speed reaches zero is a deceleration stage. The middle constant velocity stage is the constant velocity motion stage of the guiding needle. The terminal reentry stage is a process in which the guide needle accelerates backward again after slowing down and stopping. Here we explain:


            Acceleration and deceleration stage

            In order to arrange the lines evenly, the two movements of guide pin movement and skeleton rotation should meet certain coordination relations during acceleration and deceleration stage. The time for the guide needle to move one diametral width distance must be equal to the time for the skeleton to rotate once, that is, the guide needle to move just one diametral distance when the skeleton rotates once.

When adjusting the tension of the belt, first loosen this And then rotate the handle. When rotating the handle, there is an idler wheel. When the idler wheel goes in, the tension of the belt will increase, so that the winding of the enameled wire will become tighter.

Transformer winding machine:

    Similar to transformers, current transformers also work according to the principle of electromagnetic induction. The transformer transforms voltage and the current transformer transforms current. The current transformer is connected to the winding of the measured current (the number of turns is N1), called the primary winding (or primary winding, primary winding); the winding connected to the measuring instrument (the number of turns is N2) is called the secondary winding (or secondary side) Winding, secondary winding).

 Electromagnetic coil precision winding machine for winding machine

Electromagnetic coil precision winding machine for winding machine

         Winding machine, when people talk about it, usually refers to a machine that uses enameled wire as a material to form a coil. In the impression, this should be a very simple machine or even some people's printing should be summarized as a simple Power tools. But in fact, this is an industry with a very wide variety, a wide range of coverage, and complex technical characteristics.

        From the processed products, such as the single-axis CNC winding machine for processing high-frequency transformer coils, the winding axis rotates, and the winding axis moves accordingly according to the set pitch. This is a relatively simple winding machine. For example, ordinary relays are characterized by the small diameter of the enameled wire and the relatively large number of turns, so the rotation time of the main shaft of the winding machine is long.The ordinary electromagnetic coil does not have too high requirements for the accuracy of the wiring, so the main requirement for the machine is the speed High and stable tension.

        Then there is the precision electromagnetic coil, which is also an electromagnetic coil, but because this coil has temperature resistance requirements, response speed requirements, wire package volume requirements, and product consistency requirements, it is required that the winding machine be wound during winding. Each wire is neatly arranged, so to achieve this accuracy, there are strict requirements for all process factors in the winding process.

        There is the rotation accuracy of the winding spindle of the winding machine. The control accuracy of the winding machine controller, the repeating positioning accuracy of the wire screw, the roundness of the enameled wire, the diameter of the enameled wire, the rotation of the tooling behind the main shaft of the winding machine Accuracy, tension control of the enameled wire, parallelism of the two ends of the cable cavity during winding, dimensional accuracy, and also includes the structural design of the cavity during cable routing, and the design of stripping after winding. It is directly related to the success of the winding accuracy.

one. Bad salt bath:

 1. Poor enameled wire: Take out part of the enameled wire from the wire barrel (stretch a few times) and put it in salt water to judge.

 2. Poor tension of the winding machine (too large): The rotor wire package placed in salt water bubbles irregularly, and the value rises slowly. (Too small): The wire is easy to hang on the steel sheet during the winding process and the wire package is large and loose.

Analysis of winding tension of loop winding machine

                  Toroidal winding machine-Toroidal coil winding machine-Enameled wire is wound radially on the closed toroidal structure (for details, please refer to the toroidal winding machine tutorial): With the rapid development of the domestic power industry, the demand for current transformer coils Increasingly, the development of current transformer coil winding equipment is imminent. In order to meet the needs of the market, we have developed a current transformer toroidal coil winding machine based on imported equipment. During the design and testing process, we found that, The key to the design of toroidal winding machine is the control of winding tension.

    

      This automatic winding machine is composed of a frame, a pay-off mechanism, a winding head, a tape head, a clamping device, and a control system.

     loop winding machine, automatic winding machine,

    1, the working principle of toroidal winding machine

Firstly, the wires are evenly wound on the wire storage ring, and then the wires wound on the wire storage ring are wound on the skeleton by a shuttle. The skeleton is driven by the servo motor to rotate, so that the wires are evenly arranged on the skeleton when the wire is wound to a certain amount , And then wind the tape on the frame through the wire storage ring, and then wind it.

    2, analysis of winding tension

     Through our continuous practice, we have discovered that during the entire winding process, using appropriate force to wind the wire tightly on the skeleton is the key to the quality of the winding. Therefore, we will focus on the factors that affect the winding tension.

     1. The grinding moment of the rotating part of the thread bobbin

     2. The moment of inertia caused by the acceleration of the thread bobbin part (including the wire wrapped in the bobbin).

    The main part of the frictional torque is generated by the tension mechanism, which prevents the wire shuttle from moving and tightens the wire to generate winding tension.

Due to the influence of the winding ring surface and its deviation from the center position in the winding gear, even if the winding is at a constant speed, the movement speed of the thread shuttle is small and uniform, which generates the moment of inertia caused by acceleration, which affects the winding tension.


The movement speed of the thread shuttle can be regarded as composed of two speeds: one is the speed Vo equal to the speed of the pulley on the winding gear, and the other is the speed at which the thread shuttle releases the amount of wire. The former is a constant, and the latter is calculated as follows ( see picture 1)

     loop winding machine winding tension analysis 1

     So in order to reduce the acceleration of the thread bobbin, it is required:

     1. The frame profile H should be small, and the profile should be as close as possible to the center of the winding gear, that is, the value of 1 should be small.

     2. The thread hook flat diameter R should be as small as possible.

     3. The winding speed ω cannot be too high (this is in conflict with improving production efficiency).

    The approximate curve of the speed Vx and acceleration а of the mountain thread shuttle is obtained by the graphical method, and the description is as follows (see Figure 2 and Figure 3):

     loop winding machine winding tension analysis 2

     1. When the small pulley on the winding gear is at the 0° position, the speed of the thread shuttle is equal to the speed of the small pulley V0, when the speed of the thread shuttle gradually increases from 0-60°, there is a positive acceleration at this time. =600-180`) when the thread shuttle moves at a constant speed, the speed is Vm>Vo. When а=180°~263°, the speed of the thread shuttle gradually decreases. At this time, there is a negative acceleration a = 263°. The speed of the thread shuttle is equal to the pulley speed V. When а=263°~345°, the speed of the thread shuttle continues to decrease. Small, that is, it is lower than V and has a negative acceleration. When а=345°, the speed of the thread shuttle is the minimum Vo, when а=345°~360°, the speed of the thread shuttle increases gradually and there is a positive acceleration.

     2. When the winding gear rotates at a constant speed, the speed of the thread shuttle will be zero if it is small, so the friction tension mechanism always acts as a brake to keep the wire tensioned.

     3. If Vp is the average linear velocity of the thread bobbin; Vo is the linear velocity of the pulley on the winding gear; L is the perimeter of the wire of the potentiometer, then

4. When the winding speed ω is not large: the wire bobbin diameter R is small, and the potentiometer profile size H is also small. When the profile is as close as possible to the center of the winding gear, the acceleration change is small and large, and the inertia caused by the acceleration The torque is much smaller

          The winding process of the transformer winding machine directly affects the formation of the coil, and the experience is constantly summarized in the actual use of the winding machine and applied to the winding operation. Felt is a friction material used to fix the enameled wire, keep the enameled wire stable during operation, and remove dirt and burrs on the surface of the enameled wire. The clamping force of felt is also one of the sources of enameled wire tension. The tensioner is one of the most important components in the online tension device, and it is also the main component of tension control during the operation of the winding machine. Common tensioners are friction, magnetic damping, and magnetic powder braking.



   The winding machine needs many accessories to assist the normal operation of the equipment. Common accessories include spools, molds, clamps, tensioners, thread passing devices (mainly explaining the function and composition of the threading device, the threading device plays a role in conveying, protecting, and reversing during the winding operation, so that the enameled wire can be smoothly removed from (The pay-off bucket is transported to the take-up reel)



   Ceramic wheel is the most common component in stringing equipment. It has two types: full ceramic wheels and semi-ceramic wheels. All ceramic wheels are generally used for multi-wire winding occasions. Its structure is relatively simple, consisting of a bearing and a wheel body. The structure of the semi-ceramic wheel is similar to that of the full ceramic wheel, consisting of a bearing, an inner core, and a plastic retaining ring, and is generally used to wind a single enameled wire.

The function of common mode inductor is to suppress common mode interference, and it is a relatively important filter inductor.

       

       It is different from a differential mode inductor. Although the two types of inductors are filter inductors, the different functions determine the appearance and winding method will be different. For the common mode inductor, it is wound on the same core, and the two The coil diameter of each winding is the same as the number of turns, but the winding direction is opposite. A set of coils has two pins, so the common mode inductor has 4 pins; while the differential mode inductor is wound on a core and only has A coil, so it has only 2 pins, so the common mode inductance and the differential mode inductance can be distinguished from the number of pins.


     Also because the common mode inductor is two windings with opposite winding directions, the ideal winding effect is that the arrangement of the positive and negative directions is neat.

       In power transmission and power supply systems such as power plants and substations, voltage transformers are an indispensable electrical appliance. The voltage transformer for measurement specifies the accuracy level of the voltage transformer according to the error generated when the voltage is changed. Voltage transformers of level 0. 2 and above are generally called precision voltage transformers, which are mainly used in the laboratory to expand the measurement limit with the standard meter for precise measurement of voltage, power and electrical energy; or as a standard to check low standards, Low-accuracy voltage transformer; it can also be used with standard meters to test the corresponding meters.

   

       With the rapid development of science and technology and electronic application technology, the requirements for technical indicators such as the rated primary voltage and accuracy of voltage transformers are getting higher and higher, and the demand for various types of voltage transformers is increasing. In the past, voltage transformers were mostly manually wound with annular iron cores and thick enameled wires. The products were large and heavy. In the daily winding, processing and production process, the degree of mechanization was not high, the labor intensity of workers was high, and the production efficiency was low. It is necessary to improve the voltage transformer design process and develop a new type of mechanical equipment for winding the voltage transformer.
