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.
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. The control technology used is relatively backward, and its accuracy and performance are not as good as those of their European and American counterparts. Moreover, the product has low production capacity and poor stability.
In the face of technical gaps, Suzhou REPOSAL made a detailed market research and took the entire series of precision winding machines and Roche coil winding machines as breakthrough points.It valued cooperation with user companies and not only carefully understood the existing process requirements of customers. And through the company's accumulated technical database for many years, on the premise of no or little increase in costs, it actively provides new ideas and new solutions for customer process upgrades.In a specific single implementation case, this approach has undoubtedly aggravated us The execution cost of the company has reduced the company's profits, but this idea has been implemented and verified for a long time.In fact, our customers have tapped the potential of the coil winding process through our winding machine equipment and become our long-term cooperative customers.

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.
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.

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.

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.

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.

Enclosed rectangular transformer coil with a thin diameter of 0.12mm, which requires fast winding speed and convenient product loading and unloading.
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.

Magnetic winding 1mm diameter enameled wire double wire and wound
Let's now look at the tensioner, a threading process. First, the enameled wire passes through the ceramic ring at the bottom of the tensioner, and then passes through the wool felt above it. The clamping degree of the wool felt can be adjusted by passing the knob on the other side of the tensioner.
Then go through the anti-jumper, and then go over the damping wheel on the tensioner once again, then pass through an anti-jumper again, and then pass through the guide wheel on the fishing rod, this is the threading process.
Then how do we adjust to a more appropriate tension?
Let's take a look at the first one now. This handle is a tension switch. When the tension switch hits the top, the damping wheel doesn't work. When it is turned, it becomes very light. When the tension switch hits the bottom, the tensioner starts to work.
If we want to increase the tension, we adjust the knob under the bottom of the tensioner, there is a scale in this position. Through this, adjust the damping size of the damping wheel on the tensioner.
Then the handle at this position is used to adjust the back tension, which is the force of the fishing rod to bounce back. The general principle of our adjustment is that during the winding process, the fishing rod will not become weak under the interaction of the damping wheel. Sagging down, it will not be too strong and only a good swing requires a relatively large swing range, so that it can buffer and at the same time play a role in tensioning the enameled wire.
In the process of winding the coil on the precision automatic winding machine, the coil enameled wire is placed in a spiral shape in each layer. Since the direction of movement from one layer to the other changes between the opposite directions, part of the wires intersect and part of them lies in the gap of the lower layer. If the guiding structure of the lower layer does not exist, and if the number of layers exceeds a certain limit, the structure cannot be maintained, and disorderly windings are produced. At this time, as a temporary measure, it can be improved by using a separate thicker insulating layer.
When most of the circumference of the winding is parallel to the coil flange surface, the smallest coil volume can be obtained. If the winding action of the precision automatic winding machine cannot be performed correctly, the self-directing ability of the wire will be lost, and a disorderly winding structure will be produced. In general, the first layer of basic coil mainly determines the location and quality of the winding step. Therefore, in order to make the winding self-guide to be able to execute correctly, the algorithm and accuracy of the precision automatic winding machine are very high requirements.
It is not difficult to find that when the precision automatic winding machine is winding the coil, the enameled wire needs to enter the winding space as tangentially as possible. In this way, unnecessary excessive bending of the wire is avoided, and the space required for the second layer winding is minimized. For the neatly arranged coils, the winding crossover part should always be located in the area of the wire entering the winding space, and extend continuously in the opposite direction relative to the previous layer of winding in a spiral form. As a result, the larger winding width of the coil results in a larger winding step area along the circumference of the coil. Compared with the enameled wire entry point, the offset created from the first layer to the second layer causes the position of the layer steps to be different. This phenomenon repeats in each layer, thus forming a spiral cross section on the side of the winding. Since the enameled wires cross in the crossing area, the winding height is increased. As a result, a sinusoidal-wound coil with a grounded circular coil will never be circular in cross section, but radially moving windings and layered steps will produce a hump shape.
