[0052] Working principle: During operation, first, one end of the copper wire is respectively passed through the wire threading tube 205 and the wire winding tube 206, and then one end of the copper wire is fixed by the wire clamping plate. Then, the reduction motor 201 is started, and its output end will drive the rotating rod 202 to rotate. Through the settings of the rotating rod 202, the first gear 203 and the second gear 204, the wire threading tube 205 and the wire winding tube 206 will be driven to rotate. The copper wire is wound around the winding rod 211 through the wire winding tube 206, and then the first electric telescopic rod 209 is used to push the copper wire downward to fall onto the wire pay-off reel 407. Secondly, the second electric telescopic rod 501 is started to push the cutting component 500 to move relatively. The copper wire is cut by the cutting component 500 and one end is clamped by the wire clamping plate. Then, the second electric telescopic rod 501 drives the connecting frame 503 to move away from each other. Through the settings of the connecting frame 503 and the toothed plate 506, the driving gear 602 and the rotating shaft 601 are driven to rotate. Through the settings of the rotating shaft 601, the rotating disk 603 and the pawl 604, the ratchet wheel 606 is driven to rotate. Through the ratchet wheel 606 and the intermediate gear 607, the rotating gear 408 and the wire pay-off reel 407 are driven to rotate 90°. The winding operation is repeated until the wire pay-off reel 407 is completely wound. Then, the servo motor 401 is started, and its output end will drive the third gear 402 to rotate. Through the third gear 402, the annular gear 403 and the connecting column 404, the material loading disk 405 is driven to rotate to wind the next wire pay-off reel 407. Moreover, the winding operation can be carried out on two groups of wire pay-off reels 407 simultaneously, with high efficiency, high automation degree, low cost, and stable precision, which is conducive to mass production.

[0053] During the winding process, the cam 301 is driven to rotate by the rotating rod 202. Through the cam 301, the pulley 305 and the push rod 304, the piston plate 303 is repeatedly pushed to move. The first return spring 306 can play a role in resetting the piston plate 303. Therefore, air can be inhaled through the air inlet pipe and transported to the threaded pipe 310 through the communicating pipe 307, causing it to expand and elongate, thereby pushing the slide plate 309 to move downward. The slide plate 309 drives the pressing plate 313 to move downward and extrude the copper wire on the wire pay-off reel 407 to make it flat, facilitating subsequent process operations. When the winding is completed, the air release needle 314 is inserted into the air nozzle, causing the gas in the threaded pipe 310 to be discharged, and the pressing plate 313 is automatically reset upward by the second return spring 311. The content not described in detail in this description belongs to the prior art well-known to those skilled in the art.
