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.
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.

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.
Operation video of belt loop coil winding machine-controller setting
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.
As shown in the figure below, it is a sensor coil used in the medical industry. The skeleton is made of aluminum. The diameter of the enameled wire is 0.1mm. The customer requires the arrangement to be neat and free of winding defects. The company has carefully evaluated the specific requirements of the customer, because the winding process and winding are considered. 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.

Suzhou REPOSAL Electronic Mechanical Equipment Co., Ltd. is a technology enterprise specializing in R&D and production of winding equipment. For many years, it has insisted on maintaining innovation and researching and developing products with independent intellectual property rights.
For quite a long time, my country's winding machine manufacturing industry generally has the problems of low technology, small scale, free and scattered production, and insufficient technological innovation of most enterprises. Compared with related industries abroad, my country currently has fewer types of winding machines and supporting equipment.

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.
A new solution emerged -- the capillary magnetic liquid acceleration sensor, good stability, simple magnetic circuit, accurate and reliable measurement results and long service life.
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. REPOSAL® winding machine, as a professional winding process solution provider, has been developing process research on precision winding of guided fiber wire packages for many years. Good progress has been made and REPOSAL® special winding machine for guidance fiber wire wrap developed by the winding machine can set reliable process instruction information according to process requirements and accurately execute control commands to finally finish the long distance guidance fiber wire wrap without defects.

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.
In addition, the current domestic manufacturers of flexible Roche coils have limited demand for equipment. At the same time, if you want to control the pitch accuracy and alignment, the equipment research and development costs are relatively high, and the market risk is large. At the same time, for equipment users, their corresponding The supporting equipment and instruments are a large investment.
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
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.
REPOSAL® winding machine wire guided missile fiber winding forming technology has made a new breakthrough
REPOSAL ® winding machine wire guided missile fiber winding forming technology has made a new breakthrough
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:
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.
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.
The drive shaft is connected to the coiling machine
The automobile drive shaft is the part connecting the gearbox and the drive axle. It is a high speed rotating body, and the drive shaft connecting disk is the part balancing the action of the drive shaft.
The structure of the connecting disk of the drive shaft is shown in the figure below:
Existing shaft connection plate is made up of rubber vulcanization six sets of steel, its structural strength mainly provided by the rubber, in order to increase the structural strength, the manufacturer will before die casting vulcanized rubber, between the six sets of steel nylon line, its technology and processing technology is very similar to synchronous belt, between the six sets of steel round the multi-layer nylon thread, die-casting vulcanized rubber, It's a good reinforcement. Such as Mercedes-Benz, Ford have adopted this process.
Below we introduce the structure of this toroidal coil winding machine. This part is the controller and this part is the clamping base. We control the product clamping by opening and closing the handle. This position is the storage ring. The enameled wire is stored on the storage ring first, and then wound around this product. This position is a manual winding handle. Turn this handle. The steel plate can be driven manually. The steel ring has an opening. This position is an opening. The opening is opened and closed by sliding the handle up and sliding to the left. . This position is called the crimping plate, and this position is called the baffle. After the line is removed, its degree of tightness is determined by the tension of the belt. The tension of the belt is adjusted by the tension adjustment knob. 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).
This ring current transformer winding machine is generally used to wind small size current transformers. The characteristics of small size current transformers are generally wire diameter of enameled wire between 0.11-0.19mm, and the number of turns is large.
It requires accurate turns and fast winding speed.
REPOSAL this machine is fast and stable, and the speed reaches 1400RPM. Because it is stable, it can realize the operation of multiple ring current transformer winding machines by one person.

With the optimized clamping method, it only takes 2 seconds to complete the clamping.
Therefore, the rotating parts of this type of machine have a large diameter and a high speed.There are similar machines on the market, and the larger ones do not have a protective cover. Safety accidents often occur.This machine of the company has a protective cover design.

Classification and differences of common transformer winding machines
Choosing the right winding machine is the key to the production of coils. There are many types of winding machines as the basic equipment. This article mainly takes transformer winding machines as an example, and talks about its classification and differences, generally according to the voltage level or capacity of the transformer. Division, the common ones are ordinary CNC winding machines, automatic winding machines, foil winding machines, and vertical winding machines, etc.
Common accessories of transformer winding machine
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.
The company's CNC winding machine allows storage of 1000 sets of process data, and supports continuous execution of multiple sets of process data. The number of consecutive execution groups can be set from 2 to 1000 groups. This function is more complicated for the process and requires multiple external The intervention product provides great convenience and flexibility.

Debugging method and video of winding machine
1. Preparation work before turning on the winding machine.
As a kind of precision equipment, in order to keep the winding machine with good working accuracy for a long time, at the same time, the winding machine is a equipment with rotation as the main movement feature. In order to ensure the safety of the process, we need to carefully check the winding machine before the machine. Whether there is debris on the workbench, whether the screws on the winding machine are loose, whether the power switch is properly connected, whether the specification of the enameled wire meets the requirements, confirm that there are no problems with the above problems before starting the machine.
2. Parameter setting of precision winding machine
Press the reset button on the winding machine controller, or press the reset button on the front of the winding machine, the winding machine will automatically reset, at this time, if you need to set the winding machine parameters according to the production schedule. Then press the "step sequence setting" "input" button on the controller of the winding machine in turn, and then press the input key, the cursor will jump backwards in turn at the prompt light on the screen, "starting point", "width" ", "wire diameter", "number of laps", "start winding slow withdrawal", "stop slow", "high speed", "low speed", "wire direction", "winding direction" and other parameters, and finally press "confirm" "Button to confirm, and press the "reset" button to save the data and reset automatically, the parameter setting is completed.
After entering the setting interface according to the step-by-step setting input, pay attention, press the input again to scroll back, and press the-number to scroll forward. When you turn to each parameter, you can enter the corresponding number according to the actual process requirements. For this parameter, you can modify the parameter by typing in the number, or you can adjust the position in real time through the right or right key at the bottom right of the winding machine controller. At the same time, the number in the parameter box will change accordingly in real time.
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.
Detailed explanation of the operation instructions of the transformer winding machine
Transformer winding machine is a special winding equipment for winding enameled coils of transformers. During the winding process of enameled coils of transformers, winding enameled wire equipment is divided according to the specifications of the transformer. Enameled wire winding machine and foil enameled coil winding machine; there are vertical winding machines and horizontal winding machines for winding enameled coils of large power transformers.
1. Structural characteristics of transformer winding machine:
1. The mechanical transmission part of the winding machine is located inside the headboard, and the electrical part is installed on the top of the headboard. The three-phase asynchronous motor is driven by the frequency converter to realize the linear change of the spindle speed.
2. The winding machine adopts stepless speed regulation, and the controller outputs 0-10V analog voltage, which is connected to the inverter. By means of percentage, there are a total of 100 gears, which can be counted accurately, and can also be counted in reverse to automatically stop.
3. The winding machine can count reversibly, and is equipped with an electromagnetic brake device to prevent reversing when winding the enameled wire to stop, and ensure that the automatic counting will not produce errors. If you need to manually reverse, you can manually press the brake button to release, and the manual rotation can also count.

Compared with mechanical gyroscopes, fiber optic gyroscopes have no moving parts, impact resistance, high sensitivity, and long life. Therefore, fiber optic gyroscopes are widely used in high-precision and high-speed positioning scenarios and will gradually replace electromechanical gyroscopes.
The basic components of the fiber optic gyroscope are the optical path and the circuit, and the fiber is the core component of the gyroscope. The fiber winding machine for preparing high-precision fiber coils has also become the key point of the gyroscope.
However, due to the blockade of its related technologies, the fiber optic gyro winding machine has always been a key technology insurmountable. REPOSAL® Electronic Machinery Co., Ltd. actively develops fiber optic gyro winding machines in response to market demand.
Through continuous research and improvement, we automate the winding process of the fiber optic gyroscope, and compare and analyze the winding methods of various fiber coils. We have obtained that the tension control and the accuracy of the winding during the fiber winding process affect the structure of the wound fiber coil. The key factor.
By optimizing the aforementioned tension control factors and winding accuracy algorithm, the effective and stable control of reasonable tension, the effective and reliable high-precision winding control, the memory of all process parameters, and the convenience of control, a new generation of optical fiber winding machine was developed and put into production .
With the practical application of research and development results, we will continue to improve and produce high-reliability and high-efficiency fiber optic gyro winding machines.

Gear type ring coil wrapping tape machine
Compared with the belt-type loop coil tape belt machine, the gear-type loop coil tape belt machine has a larger processing range and more storage capacity. Our company's gear-type loop coil belt tape machine can be coated with polyester film and polymer Imide, cloth tape, glass fiber tape, etc.
We now open the clamping seat of the gear-type ring coil tape belt machine, the storage ring opens, and then put the product on, the storage ring buckles, the clamping seat merges, and then pay attention to the insulating tape must pass through the middle of the scissors, etc. Cut it off with scissors at once, and then go in from any bearing above the storage ring from the outside to fix the tape head behind the storage ring. The first few laps are slow because they are in storage. Ok, the product is finished, now we take it off, and then close the storage ring, the clamping seat is restored.
General debugging method of winding machine
Some people look at the winding machine and feel a bit like a lathe, but in fact the winding machine has to wind a neat coil. Compared with the smoothness of the lathe, it is much more complicated, so we will find that the lathe has a long time ago The national standard has quantitative standards for its various indicators, but the winding quality of the winding machine has many condensing factors and it is difficult to quantify.
It is precisely because of the above reasons that at first I feel that the winding machine should be very easy to debug, but after the facts, I will be a little frustrated. Although the winding machine debugging is indeed more complicated than imagined, but if we master the basic laws After that, it's not difficult to practice more.
First of all, we must have a preliminary understanding of the structure of the winding machine, otherwise, we are not familiar with the structure of the winding machine, and there is no professional technical personnel training. Automatic debugging of the winding machine will be incompetent.

Influence of low enameled stress on formability in the process of winding enameled wire by winding machine
Manufacturers of small motors and coils are faced with the need to increase production capacity and improve product reliability, and they need to continuously reduce the damage to the insulation properties of enameled wire caused by coil winding and assembly. Due to the large stretch during the coil winding and assembly process, the insulating layer of the enameled wire must have good flexibility, and the enameled wire should also have good formability (softness of the wire).
1 The formability of the enameled wire The mechanical properties of the enameled wire are divided into the mechanical properties of the conductor and the paint film. In the process of winding the enameled wire, in the wire embedding process, and in the electrical products using the enameled wire coil as a component, mechanical stress acts on the enameled wire during operation, so the enameled wire may be elongated and the paint film is damaged. etc. phenomenon. Therefore, enameled wire has the requirements of elongation, rebound angle, softness, tensile strength, paint film elasticity, paint film adhesion and scratch resistance.
1.1 Mechanical properties of conductors: softness, elongation, rebound angle, and tensile strength.
Elongation reflects the plastic deformation of the material and is used to assess the ductility of enameled wires. The springback angle and softness reflect the elastic deformation of the material and are used to evaluate the softness of the enameled wire. The tensile strength is related to the recovery recrystallization degree of the conductor and the grain size of the recovered tissue. The tensile strength, softness and elongation reflect the quality of the copper material and the degree of enameled annealing, which have a great impact on the quality of the winding. great relationship.
In the process of enameled wire coating, if the number of paint passes and the number of loops is too large, and the diameter of the guide wheel is not large enough, the wire will be continuously deformed by alternating tension and compression, resulting in the distortion of the lattice. It breaks easily when stretched. When the enameled wire is running, the wire is subjected to excessive tension, which will make the wire thinner. At this time, due to the displacement of atoms or ions on the lattice due to sliding, residual internal stress has been formed, so the wire is brittle and elongated. rate and softness rate decreased.
