Foil Winding Machine

In industries such as transformer manufacturing, improving production efficiency is one of the key factors for enterprises to enhance competitiveness. NOMURA Automation Technology (Suzhou) Co., Ltd., as a high-tech enterprise specializing in the research and production of winding equipment in the industry, has launched the Yeyi foil winding machine, which has significantly improved the production efficiency of the enterprise with rich and advanced automation functions.

The automated unwinding and feeding system of NOMURA foil winding machine has opened the first step of efficient production. Traditional unwinding and feeding often rely on manual operation, which is inefficient and prone to unstable feeding. The NOMURA foil winding machine is equipped with an automatically adjustable unwinding device, which can quickly adjust the length and expansion range of the feeding cylinder through a high-precision mechanical adjustment mechanism according to different specifications of foil rolls. No matter how the width and inner diameter of the foil roll change, it can achieve fast and accurate installation. At the same time, the feeding device adopts advanced servo motor drive technology, and the operator only needs to input the corresponding parameters in the control system, and the equipment can respond quickly and accurately control the feeding speed and amount of foil material. For example, in the foil winding of small transformers, the width of the foil is narrow and the inner diameter of the coil is small. The unwinding device of the NOMURA foil winding machine can be quickly adjusted in place, and the feeding device can smoothly feed the foil into the winding area at a precise speed. The entire process is efficient and stable. Compared with manual operation, it greatly shortens the preparation time, improves the efficiency of the feeding process, and saves more time for subsequent winding processes.

The advanced tension and correction automation system is the core of NOMURA foil winding machine to improve production efficiency. During the winding process of transformer foil coils, unstable foil tension and positional deviation are important factors affecting product quality and production efficiency. The NOMURA foil winding machine adopts advanced segmented tension control technology, intelligently matching tension control modes for foil materials of different thicknesses and materials. For thin and narrow foil materials, the air compression dynamic tension method is adopted, and the working air pressure of the air compression actuator is precisely controlled by an electrical proportional valve to ensure accurate braking torque, maintain stable foil tension, and prevent foil stretching deformation. For thick and wide foil materials, motor reverse braking combined with air compression braking is used to meet high tension requirements while performing correction and compensation to improve tension control accuracy. In terms of correction, the high-precision photoelectric induction automatic correction device monitors the position of the foil in real time. Once there is a deviation, the servo motor drives the adjustment mechanism to respond immediately and quickly correct the foil to the correct position, with a correction accuracy of up to ± 0.1mm. This precise tension and correction system greatly reduces winding interruptions and product defect rates caused by tension and position issues, without the need for frequent shutdown adjustments, enabling the production process to continue and operate efficiently. Taking the foil winding of large power transformers as an example, due to the large coil specifications and long winding time, the tension and correction system of NOMURA foil winding machine can maintain stable operation during long-term operation, ensuring that each coil of foil material can be wound accurately, greatly improving overall production efficiency.

The automated mechanism for winding and pressing provides a solid guarantee for the efficient production of Yeyi foil winding machine. The spindle of the winding machine is driven by a high-precision drive device, which has strong torque output and stable speed control capability. When faced with the task of winding transformer foil coils with different inner and outer diameters, the control system flexibly adjusts the spindle speed and torque. When winding large coils, provide sufficient torque to drive the heavy wire mold to rotate; When winding small coils, precise control of speed enables fine operation. At the same time, the clamping device has also achieved automatic adjustment. The airbag plate compression device can adjust the inflation pressure of the airbag to evenly compress the coils in the winding process. For coils of different thicknesses, the pressure can be easily adjusted to meet the requirements. The servo motor clamping method is more intelligent, which can accurately adjust the clamping force and position based on the real-time status and specification parameters of the coil, ensuring that the coil is tightly and neatly wound, avoiding loose or deformed problems. This automated winding and pressing mechanism greatly improves the winding speed while ensuring product quality. In the production of foil coils for electronic transformers, the NOMURA foil winding machine can quickly complete winding and pressing operations. Compared to traditional equipment, it can produce more qualified coils per unit time, significantly improving the production efficiency of enterprises.

A series of automated auxiliary devices have further improved the efficient production process of NOMURA foil winding machine. The automatic cutting mechanism adopts an adjustable electric rolling cutting machine, which automatically adjusts the position and force of the cutting tool according to the thickness and width of the foil material. After winding is completed, the foil strip is quickly and neatly cut with minimal cutting error, without the need for manual secondary trimming, saving time. The welding device is used for connecting end copper bars, and the welding gun can be flexibly adjusted in multiple directions. The welding stroke is controlled by a frequency converter driven motor, and the speed is infinitely adjustable. Operators only need to set parameters in the control system according to the coil specifications, and the welding device can automatically complete high-quality welding, ensuring that the welding points are firm and have good conductivity. The interlayer insulation unwinding system adopts an inflatable shaft unwinding reel, which achieves constant tension control through reverse torque of an AC variable frequency motor, avoiding mechanical friction and noise. At the same time, the width direction position of the insulation material can be manually and independently adjusted to adapt to interlayer insulation materials of different widths, ensuring that the insulation material is evenly and stably laid between the foil materials. These automated auxiliary devices work together, from foil cutting, end welding to interlayer insulation laying, without frequent manual intervention, greatly improving production efficiency and achieving full process automation of foil coil winding.
