DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, in conjunction with the accompanying drawings in the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a wire winding device for motor production includes a workbench 1. A clamping mechanism for clamping the end of the copper wire is installed at the middle position of the top end of the workbench 1. A displacement mechanism is installed on one side of the clamping mechanism at the top of the workbench 1, and a lifting mechanism is installed on the top of the workbench 1; the lifting mechanism is used to drive the copper wire to wind around the motor rotor, and the displacement mechanism is used to drive the lifting mechanism to move along the length direction of the workbench 1.
[0020] In this embodiment: First, the rotor of the motor that needs to be wound with copper wire is installed on the corresponding rotating platform, and the rotating platform can drive the motor rotor to rotate reciprocally and rotate 180 degrees;
[0021] After that, the wire is passed through the lifting mechanism, and then the clamping mechanism is started to clamp the end of the copper wire passing through the lifting mechanism. Then, the rotating platform installed with the motor rotor is started, and the rotating platform drives the motor rotor to rotate reciprocally, and the reciprocating rotation angle is the angle between two adjacent slots of the motor rotor;
[0022] When the motor rotor makes its first rotation, the wire is located in a slot, and the lowest end of the lifting mechanism is located above the motor rotor. The motor rotor that rotates for the first time drives another adjacent slot to move to the bottom of the lifting mechanism. At this time, the contact position between the wire and the slot wall is bent, and the contact position between the copper wire and the top of the slot wall and the lifting mechanism is in a "Z" shape rotated 90 degrees. The lifting mechanism moves downward, pushing the copper wire downward until the lowest end of the lifting mechanism is located below the motor rotor. At this time, the copper wire is located in another slot in a "U" shape, half of the U-shaped structure is in contact with the inner wall of the rotor slot, and the other half of the U-shaped structure is located in the middle of the rotor slot. At this time, the displacement mechanism drives the lifting mechanism to move, and the displacement mechanism moves, driving The copper wire moves outward, and during the outward movement of half of the U-shaped copper wire in contact with the rotor slot wall, it is hooked by the rotor teeth between the two rotor slots, forming a restriction and unable to be completely moved out of the rotor slot, while the other half of the U-shaped copper wire moves out smoothly. At this time, the rotating platform drives the motor rotor to reset and rotate. At this time, the lowest end of the lifting mechanism is aligned with the rotor slot at the initial position again, and then the displacement mechanism drives the lifting mechanism to reset, and the reset lifting mechanism moves upward again. Through the above process, the copper wire is wound on the rotor teeth to complete the winding effect. After the copper wire is wound around the outer wall of one rotor tooth, the clamping mechanism can be cancelled to clamp the end of the copper wire. Then the rotating platform drives the motor rotor to rotate 180 degrees to wind the copper wire around the outer wall of another symmetrical rotor tooth.
[0023] Please refer to Figure 1 , Figure 2 and Figure 3 The displacement mechanism includes a No. 2 guide rail 5 fixedly mounted on the top of the workbench 1, a No. 2 slider 17 is slidably connected to the inner wall of the No. 2 guide rail 5, both ends of the No. 2 slider 17 penetrate to the outer side of the No. 2 guide rail 5, and long grooves for the No. 2 slider 17 to slide are opened on both sides of the No. 2 guide rail 5, a one-way screw 7 is threadedly connected to the inner wall of the No. 2 slider 17, one end of the two one-way screws 7 are coaxially connected to a synchronous wheel 9, and the two synchronous wheels 9 are connected through a synchronous belt 10.

Two sets of support ears are installed on the top of the workbench 1, and the support ears are rotatably connected to the one-way screw 7.
[0024] In this embodiment: when the displacement mechanism moves, by starting the No. 2 forward and reverse motor 8, the No. 2 forward and reverse motor 8 drives the synchronous wheel 9 connected thereto to rotate, and the synchronous wheel 9 drives another synchronous wheel 9 to rotate through the synchronous belt 10, and the other synchronous wheel 9 drives the one-way screw 7 connected thereto to rotate, and the rotating one-way screw 7 drives the No. 2 slider 17 connected thereto to move, and the No. 2 slider 17 moves along the No. 2 guide rail 5, and the moving No. 2 slider 17 drives the lifting mechanism to move.
