[0026] The present invention also discloses a method for winding wires on a motor stator, which specifically includes the following steps: Step 1, stator processing and positioning: According to Figure 1 and Figure 9 as shown, first place the stator 4 inside the fitting frame 3. Then, rotate the bidirectional threaded rod 817, causing the threaded sleeve 818 to drive the converging ring 819 to move towards the middle of the bidirectional threaded rod 817. When the converging ring 819 moves, it will press against the inclined surface of the bending rod 816, causing several bending rods 816 to drive several storage frames 804 to move towards the center of the fitting frame 3. When the storage frame 804 moves to the limit position, the storage frame 804 at the top will block and limit the top of the stator 4; Step 2, stator wire winding: Use the on-site winding device to regularly wind a copper wire coil 703 with a specified number of turns on the surface of the winding die frame 702. Then, start the electric telescopic rod 704 in the automatic assembly mechanism 7, causing the extending end of the electric telescopic rod 704 to drive the winding die frame 702 to descend to the coil assembly position. After the descent is completed, simultaneously use the U-shaped assembly frame 715 to clamp the copper wire coil 703 in the stator 4 wire grooves, and while assembling the copper wire coil 703 on the stator 4, simultaneously perform multi-station compaction on the already assembled copper wire coil 703; The specific steps are as follows: According to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 13 、 Figure 14 and Figure 15As shown, the electric telescopic rod 704 is started, and the extended end of the electric telescopic rod 704 drives the outer expansion ring 705 and the handle pressure plate 706 to descend. The bottom of the handle pressure plate 706 is blocked by the L-shaped movable frame 708, so the L-shaped movable frame 708, the inclined block 707 and the winding mold frame 702 are synchronously descended until the winding mold frame 702 descends to the top of the U-shaped base 709. When the winding mold frame 702 descends to the top of the U-shaped base 709, the winding mold frame 702 is flush with the stator 4. When the winding mold frame 702 descends to the top of the U-shaped base 709, the inclined expansion plate 710 will be squeezed and contacted with the descending inclined block 707, causing the inclined block 707 to retract and cling to the side of the inclined expansion plate 710. Because the inclined block 707 is displaced by force, the inclined block 707 will carry the L-shaped movable frame 708 and stagger the bottom of the handle pressure plate 706. When the handle pressing plate 706 is lowered to drive the inclined surface block 707 to squeeze and contact the side of the inclined surface expansion plate 710, the outer expansion ring 705 will be lowered along with the handle pressing plate 706, and will be located on the inclined surface of several inclined rods 716 and contact the inclined surface of the inclined rods 716. As the outer expansion ring 705 and the handle pressing plate 706 continue to fall, the outer expansion ring 705 will squeeze the inclined rods 716, prompting the inclined rods 716 to drive the U-shaped assembly frame 715 to move, and finally prompting the U-shaped assembly frame 715 in the limit frame 701 to assemble the copper wire coil 703 in the wiring trough of the matching frame 3, and the other U-shaped assembly frames 715 move synchronously, so as to repeatedly compact the copper wire coil 703 in the assembled position. As the handle pressing plate 706 continues to descend along with the above-mentioned outward expansion ring 705, the handle pressing plate 706 will carry the flip plate 712 to contact the top of the L-shaped movable frame 708. The descending flip plate 712 will be blocked by the L-shaped movable frame 708 and will flip upward, and will be misaligned with the L-shaped movable frame 708, and will eventually be at the bottom of the horizontal bend of the L-shaped movable frame 708, and will be reset and unfolded synchronously. When the handle pressing plate 706 is reset later, the handle pressing plate 706 will pre-expand and squeeze the L-shaped movable frame 708 through the upper inclined surface of the flip plate 712, so that the L-shaped movable frame 708 will be pushed outward. The movable frame 708 drives the inclined block 707 and the inclined expansion plate 710 to break away from the extrusion and close fit, and the flip plate 712 synchronously expands and squeezes with the L-shaped movable frame 708 to accompany the rise and reset of the handle pressure plate 706 and drive the winding mold frame 702 to rise and reset. After the winding mold frame 702 is pulled up to the top of the inner cavity of the limit frame 701, the handle pressure plate 706 will continue to rise, prompting the flip plate 712 to increase the force of squeezing and expanding the L-shaped movable frame 708, prompting the flip plate 712 to pass over the top of the L-shaped movable frame 708 and restore its original position.

[0027] Step 3: Temporary winding binding: When the U-shaped assembly frame 715 in the limit frame 701 is driven by the electric telescopic rod 704 to assemble the copper wire coil 703, the U-shaped assembly frame 715 synchronously drives the anti-loosening and tightening mechanism 8, so that the U-shaped tightening frame 810 and the movable top plate 811 in the anti-loosening and tightening mechanism 8 bind the copper wire coil 703 in the stator 4 slot; The specific steps are as follows: According to Figure 3 , Figure 4 , Figure 5 , Figure 10 , Figure 11 , Figure 12 and Figure 13 shown, the front U-shaped assembly frame 715 is squeezed and matched by the outer expansion ring 705 and the inclined rod 716. The front U-shaped assembly frame 715 will move forward to assemble the copper wire coil 703. The front U-shaped assembly frame 715 synchronously drives the two connecting plates 822 to move. The movement of the two connecting plates 822 will be in extrusion contact with the tooth plate 815, prompting the tooth plate 815 to move. The tooth plate 815 moves under force and meshes with the third gear 813. The third gear 813 synchronously meshes reversely with the tooth limit block 814, prompting the telescopic plate 805 to extend from the storage frame 804. The telescopic plate 805 synchronously drives the U-shaped tightening frame 810 and the movable top plate 811 to move and approach the copper wire coil 703. When the movable top plate 811 moves, it will gradually disengage from the roller 812, so that the U-shaped tightening frame 810 and the movable top plate 811 are pulled by the return rod 808 and move vertically towards the sleeve 807. Finally, the U-shaped tightening frame 810 will be located at the rear side of the copper wire coil 703 that is moving forward on the front side. After the front U-shaped assembly frame 715 drives the connecting plate 822 to reset, the telescopic plate 805 will drive the U-shaped tightening frame 810 to tighten the copper wire coil 703 assembled on the front side from the back to the front. There are balls on the surface of the movable top plate 811.
