[0033] The working principle of the present invention is as follows: in the working state, the ring plug 221 on the upper winding ring 216 is inserted into the ring slot 222 of the lower winding ring 220, and the ring plug 221 of the lower winding ring 220 is inserted into the ring slot 222 on the upper winding ring 216, and the ring plug 221 and the ring slot 222 are both arc-shaped, and the ring plug 221 and the ring slot 222 are coaxial with the upper winding ring 216, so that the upper winding ring 216 and the lower winding ring 220 form a complete gear. The position of the lower winding ring 220 is limited by the baffle on the upper winding ring 216, and the upper winding ring 216 and the lower winding ring 220 are stably matched by the blocking of the limit slider 218 to avoid the misalignment of the lower winding ring 220 and the upper winding ring 216; the iron core 106 penetrates into the gear composed of the upper winding ring 216 and the lower winding ring 220, and the lifting plate 104 is lifted and lowered by the telescopic piston rod of the execution cylinder 102, thereby driving the iron core 106 to lift and lower, and adjusting the height of the iron core 106.

[0034] The copper wire on the copper wire roller 214 is wound onto a part of the iron core 106, and then the winding motor 212 and the execution motor 103 are started. The execution motor 103 drives the pressure wheel 105 to rotate through the execution pulley, thereby driving the iron core 106 to rotate; the winding motor 212 drives the winding gear 211 to rotate and drives the gear composed of the upper winding ring 216 and the lower winding ring 220 to rotate, so that the copper wire shaft on the copper wire roller 214 rotates on the copper wire roller 214 to release the wire, and the copper wire is guided by the guide wheel 215. The copper wire roller 214 is fixedly installed with the upper winding ring 216, and the copper wire roller 214 rotates with the gear composed of the upper winding ring 216 and the lower winding ring 220 to wind the copper wire on the copper wire roller 214 onto the iron core 106. For each circle of copper wire wound on the iron core 106, the execution motor 103 controls the pressure wheel 105 to drive the iron core 106 to rotate a preset angle, so that the copper wire is evenly wound onto the iron core 106.

[0035] When the winding gear 211 rotates, the winding gear 211 drives the spline shaft 208 to rotate through the sliding cylinder 210, the spline shaft 208 drives the winding gear 1 207 to rotate, and the winding gear 1 207 drives the winding gear ring 204 to rotate, so that the gear composed of the upper winding ring 216 and the lower winding ring 220 rotates synchronously with the winding gear ring 204, so that the locking rod 228 is always coaxial with the locking hole 219. When the copper wire on the iron core 106 is wound and the upper winding ring 216 stops rotating, the upper winding ring 216 engages with the winding gear 211, and the upper winding ring 216 is above the lower winding ring 220, cutting the copper wire connecting the copper wire roller 214 and the iron core 106.

[0036] The actuator cylinder 102 is started to extend the piston rod to push the lifting plate 104 to move vertically upward, and the moving motor 202 is started to drive the screw 205 to rotate, driving the mounting frame 206 to move toward the bracket 201, driving the sliding sleeve 209 to slide on the fixed inner plate 213, and driving the locking rod 228 to approach the locking hole 219. The first end of one of the locking rods 228 contacts the inclined surface on the limit slider 218, pushing the limit slider 218 to slide on the upper winding ring 216, exposing a locking hole 219 blocked by the limit slider 218, and then the two locking rods 228 are respectively inserted into a locking hole 219, and the first end of the locking rod 228 pushes the locking block 225 to slide in the inner groove 223, and then the locking ring groove 231 moves to the position corresponding to the locking block 225, and the locking block 225 is inserted into the locking ring groove 231 by the elastic force of the return spring 224.

[0037] Then the moving motor 202 reverses, driving the mounting frame 206 to move away from the bracket 201, driving the winding gear ring 204 and the locking rod 228 to move, the locking rod 228 drives the locking block 225 to move, and the locking block 225 drives the lower winding ring 220 to move, so that the lower winding ring 220 is separated from the upper winding ring 216, completing the disassembly of the upper winding ring 216 and the lower winding ring 220. At this time, the position of the upper winding ring 216 and the winding gear ring 204 is restricted by the winding gear 2 211 and the winding gear 1 207, and cannot rotate.

[0038] Then, the actuator cylinder 102 is driven to drive the lifting plate 104 to move up and down, the iron core 106 with the copper wire wound is taken out, and the unwound iron core 106 is reinstalled, and then the moving motor 202 is started to drive the mounting frame 206, the winding gear ring 204, the locking plug rod 228, and the lower winding ring 220 to move toward the bracket 201, so that the ring plug plate 221 on the upper winding ring 216 is inserted into the ring slot 222 of the lower winding ring 220, and the lower winding ring 220 is matched with the upper winding ring 216 again to form a complete The gear is then started, and the indexing motor 229 is started to drive the indexing pulley 230 to rotate, which drives the winding pulley 227 to rotate, and drives the locking rod 228 to rotate, pushing the locking block 225 out of the locking ring groove 231, and then the mobile motor 202 drives the locking rod 228 to return to the initial position, and the limit slider 218 re-limits the lower winding ring 220 under the elastic force of the limit spring 217, completing the assembly of the upper winding ring 216 and the lower winding ring 220, and automatically winding the next iron core 106.
