Description

Technical Field

[0001] This utility model relates to the field of brushless motor manufacturing technology, specifically to a hollow cup winding device for DC brushless motors. Background Technology

[0002] The hollow cup winding equipment for brushless DC motors is an automated device specifically designed for manufacturing the core component of brushless DC motors—the hollow cup winding. Brushless DC motors are widely used in drones, medical devices, robots, and other equipment due to their high efficiency, low noise, and long lifespan. As a critical component of the motor, the quality of the hollow cup winding directly affects the motor's performance. This equipment, through a high-precision control system, evenly winds copper wire onto the hollow cup frame according to a preset number of turns, layers, and angle, ensuring the tightness and consistency of the winding and guaranteeing the reliability and safety of the production process. By using this equipment, manufacturers can significantly reduce labor costs, improve product consistency and yield, thereby meeting the stringent requirements of the high-end motor market for high-performance windings.

[0003] According to the Chinese Utility Model Publication No. CN218335686U, a hollow cup winding device for a brushless DC motor is disclosed. This device has a compact and reasonable structure, is simple to operate, and is convenient to use. First, the coil to be used is hung on the hanging rod. Then, the hollow cup is clamped by the clamping mechanism. Next, one end of the coil is fixed on the hollow cup. Finally, the copper wire is quickly and orderly wound onto the hollow cup by the clamping mechanism and the winding mechanism. This saves time and effort while improving the winding quality and ensuring the quality of the subsequent finished product.

[0004] However, there are some issues to consider when implementing the above technical solutions: First, the device clamps and fixes the hollow cup with a clamping plate. When manually placing the hollow cup, due to the lack of precise positioning assistance, the operator has difficulty accurately controlling the position of the hollow cup, resulting in a positional deviation. This deviation will directly affect the uniformity and tightness of the winding, thereby reducing the quality of the winding and even causing subsequent motor performance problems. Second, the device changes the relative position of the wire harness through the winding mechanism, but during the transmission of the wire harness, the raw material tray and the winding mechanism are not in the same radial position, and the wire harness will be subject to friction, resulting in wire harness wear and affecting product quality.

The vertical guide roller 401 is fixedly connected to the top center of the base 1. A horizontal guide roller 402 is provided on one side of the vertical guide roller 401. Three sets of horizontal guide rollers 402 are provided. The horizontal guide rollers 402 gradually narrow from right to left. A wire feeder 403 is provided on one side of the horizontal guide rollers 402. The wire bundle passes through the vertical guide roller 401, maintaining a relative height, and then passes through the horizontal guide roller 402, gradually converging inward before passing through the wire feeder 403.

[0028] Specifically, the bottom end of the first electric telescopic rod 404 is fixedly connected to the base 1, and the top end of the first electric telescopic rod 404 is fixedly connected to the first rotating seat 405. The inner side of the first rotating seat 405 is rotatably connected to the support roller 406. The support roller 406 is thick at both ends and thin in the middle.

The top of the electric slider 502 is fixedly connected to the second rotating seat 503. The electric slider 502 slides on the slide rail 501 to change the position of the second rotating seat 503 so that the wire harness is aligned with the winding position, thereby improving product quality.

[0030] Specifically, a winding motor 504 is fixedly connected to the rear end of the second rotating seat 503, and a power roller 505 is fixedly connected to the output shaft of the winding motor 504.

Together with the power roller 505, the hollow cup is clamped and the center of the hollow cup is kept on the same straight line as the rotation center, which improves the uniformity and tightness of the winding and ensures the quality of the winding. Then, the winding motor 504 drives the power roller 505 to rotate so that the wire harness is wound on the hollow cup. At the same time, the electric slider 502 slides on the slide rail 501 to change the position of the second rotating seat 503 so that the wire harness is aligned with the winding position and improves the product quality. At the same time, the first electric telescopic rod 404 extends and retracts to adjust the height of the support roller 406 to keep the height of the wire harness and the hollow cup consistent and improve the winding quality.
