REPOSAL winding machine continuous innovation to consolidate brand value
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.
For actively engaged in innovative REPOSAL winding machine, user support is essential. On the one hand, only users actively purchase and use the winding machine we developed can find defects and problems in the application, so as to continuously improve the design scheme, technical route or production process, so as to continuously improve product quality and reliability; on the other hand , Winding machines develop new products for a long time, have a large investment, and have a high risk. Only when they are sold can they recover costs and make profits, and they can also use funds to invest in a new round of research and development, forming a virtuous circle; otherwise, it will easily cause a capital chain Broke, get into trouble or even go bankrupt. In fact, it is not uncommon to see examples of "death on the road" because innovative products cannot be sold; "non-innovation is to wait for death, innovation is to find death", which is not groundless.
From the rise of the automobile industry in Japan and South Korea, it is easier to see the importance of user support. In the 1950s and 1960s, the automobile industries of the two countries started difficultly under the background of Europe and the United States. Their difficulty can be imagined. In the case of no export, it is precisely because of the strong support of the national government and the enthusiastic support of the domestic people that their cars can be increasingly improved, mature, and successfully go to the world. REPOSAL winding machine through the user support, insist on continuous Innovation has also been recognized by more and more customers everywhere.
Of course, companies that are determined to innovate and have high ambitions, in addition to continuous investment in improving independent innovation, also pay attention to production management and quality control. REPOSAL winding machine believes that only excellent quality and reliable performance can win Customer support and trust.
The cross section of an R-type transformer is like the letter R, so it is called an R-type transformer. The application of R-type transformers in high-power electrical appliances can reduce inrush current. R-type transformers are one of the dry-type transformers. The iron core is made of continuous high-quality oriented cold-rolled silicon steel strip from thin to thick, and then from thick to thin. The final cross-section is close to a circle, and the shape is an uncut closed rectangle, and then passes through a special R-shaped transformer The winding machine winds the coarse secondary on its PBT skeleton. Therefore, the transformer thus manufactured has no noise, low magnetic leakage, low no-load current, low iron loss, and high efficiency; and because the coil is cylindrical, the length of the coil copper wire wound by the R-type transformer winding machine short, so , Low internal resistance, low copper consumption, low temperature rise, low over-carrier motion, and better explosive force than toroidal transformers; in addition, the primary and secondary coils are separately wound with flame-retardant PBT engineering plastic skeletons, thus high electrical strength , Good flame retardancy.
However, the manufacturing process is more complicated. The second is the winding of the coil. Because it is wound in a closed iron core, the PBT is composed of two parts, and then the R-type transformer winding machine drives the PBT skeleton to wind, and the winding accuracy is affected. A certain influence, one is the shape of its iron core, because its expanded shape is a spinning cone, so its mold and material utilization are relatively low.
With the development of R-type transformer winding machines, the reduction of manufacturing costs, and the improvement of quality stability, R-type transformers are being favored by more and more electronics industries with their novel and unique structure and excellent electromagnetic performance. Especially suitable for medical equipment, display equipment, audio equipment, office equipment.

On August 6, the first ultra-precision flow tube metering heating wire winding machine independently developed by Suzhou REPOSAL® Electronic Mechanical Equipment Co., Ltd. successfully completed the test, and the performance of each index reached the level of the industry in advanced foreign countries.
At present, the ultra-precision flow tube, a metal tube with a diameter of 0.4mm, a wall thickness of 0.1mm, an inner diameter of 0.2mm, and a special metal wire of 0.03mm are wound. There are single-layer winding, double-layer winding, and double-layer butt-joining winding. Flow tube is required There is no deformation at both ends and the metal wires are arranged neatly. This process technology has been monopolized by foreign companies for a long time, and the price is high, which severely restricts the research and achievement of ultra-precision flow meters in China.
Ultra-precision flow tube metering heating wire winding machine is an important symbol of independent innovation ability. The research of this equipment has broken through many key technologies of precision winding technology and optimized the process and mechanical structure. In the next step, Suzhou REPOSAL Electronic Machinery Equipment Co., Ltd. will further optimize the design and production process, reduce the cost of the whole machine, make it better to market, and accelerate the application and industrialization of localized precision winding machines.
Analysis and Solution of Common Defects in Coil Winding Machine
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.
Solution: The enameled wire passing through the tension system of the winding machine must be checked with a spring balance on the tension meter before winding.
3. Wool felting carbon. Damage to the winding wheel of each winding machine. Damage to the small bearing of each winding: The rotor wire package placed in salt water bubbling irregularly, and the value rises faster.
Solution: Replace the damaged wool felt, thread roller, and small bearing
4. Damage to the winding mold of the winding machine (wire mold): The rotor wire package placed in salt water bubbles regularly, and the bubble position is in the upper, lower or middle of the iron core (each slot is in the same position). The value rises quickly.
(Hook wire set): The rotor wire put in the salt water bubbling on the neck (the damage part should be visible).
Solution: Check the mold. Determine the position. Grind and polish.
5. Poor debugging of the winding machine caused the indexing change during the winding process (and even scratches on the bottom of the enameled wire): the winding mold of the winding machine was not adjusted well at the center of the hook sleeve, and the balance of the winding mold was not adjusted properly. Hook thread set

Transformer insulating crepe paper has good mechanical strength, high withstand voltage strength, wrinkles on the surface, and a certain degree of toughness. Moreover, it is easy to cut. After the transformer is wound and formed, it still maintains a certain strength in the oil immersion of the rear tooling. This feature can very well protect the enameled wire of the transformer from being squeezed and broken, that is, it meets the insulation requirements. It also meets the mechanical performance requirements.
Therefore, it is widely used for transformer insulation. Generally used in transformers, but less used in transformers, because the core structure of transformers is annular, because the surface of the insulating crepe paper has wrinkles and friction is large, so the annular wrapping machine is used. Winding is more difficult, so in general, if crepe paper is required for the transformer coil, manual winding is used. We have successfully overcome this problem by improving the details.
