　　　          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.

 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. We have also accumulated more technical data for our research and development direction and solutions through proactive improvement of individual cases, so as to achieve continuous innovation.

         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.

Such as Mercedes-Benz, Ford have adopted this process.

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.

Crossover coil winding machine

       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.

High-speed precision winding machine SP-112DHS

      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.

      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.
