[0067] Among them, the present invention sets an internal winding jig 300, an external winding jig 400, a moving assembly 600 and a driving positioning assembly 500. When winding the double-layer enameled wire, one end of the enameled wire is first placed in the L-shaped plate 3031, and the hexagonal bolt 3032 is tightened with a wrench to fix one end of the enameled wire. Then, the enameled wire is pressed into the first spiral guide groove 302, and the driving motor 502 is started. The rotation of the driving motor 502 drives the active gear disc 506 to rotate, and the rotation of the active gear disc 506 drives the driven gear ring 508 and the connecting tube 507 to rotate. The rotation of the connecting tube 507 drives the concave rotating disk 501 to rotate, and the rotation of the concave rotating disk 501 drives the fixed column 301 to rotate. The rotation of the fixed column 301 realizes the enameled wire in the first spiral guide groove. The inner wall of 302 is wound and coiled, that is, the inner layer of the double-layer enameled wire is wound, and then the rotating motor 602 is started. The rotation of the rotating motor 602 drives the threaded column 601 to rotate, and the rotation of the threaded column 601 drives the Z-shaped plate 603 to move, thereby driving the sleeve 401 to move horizontally and be sleeved on the outer surface of the fixed column 301.

An L-shaped rod 703 is fixed on the lower surface of the slider 702, and a movable plate 704 is fixed on the end of the L-shaped rod 703. A guide hole 705 for the enameled wire to pass through is opened on the surface of the movable plate 704.

[0069] Specifically, the position of the enameled wire can be guided during winding under the action of the movable plate 704 and the guide hole 705 , thereby facilitating winding of the enameled wire.

[0070] Please refer to Figure 5 and Figure 7A reciprocating screw 706 that passes through the fixed plate 200 is rotatably provided on the side of the fixed plate 200, and one end of the reciprocating screw 706 is rotatably connected to the inner wall of the fixed frame 701.

The rotation of the reciprocating screw 706 drives the slider 702 to move. The movement of the slider 702 drives the moving plate 704 to move through the L-shaped rod 703. The movement of the moving plate 704 drives the enameled wire passing through the guide hole 705 to automatically move, thereby making it easier for the enameled wire to be wound on the surface of the fixed column 301 and the sleeve 401.

[0073] Please refer to Figure 8 The lower surface of the movable plate 704 is provided with a shearing assembly 800 for cutting the enameled wire.

The surfaces of the two rectangular blocks 803 are provided with a third threaded hole threadedly connected to the outer surface of the bidirectional screw 801.

[0074] Specifically, the rotation of the servo motor 802 can drive the bidirectional lead screw 801 to rotate, and the rotation of the bidirectional lead screw 801 drives the two rectangular blocks 803 to move toward the middle at the same time, thereby driving the two cutters 804 to automatically cut the enameled wire.

[0075] Among them, the present invention sets a shearing component 800, which can start the servo motor 802 after the winding is completed. The rotation of the servo motor 802 drives the bidirectional screw 801 to rotate, and the rotation of the bidirectional screw 801 drives the two rectangular blocks 803 to move toward the middle at the same time, thereby driving the two cutters 804 to move toward the middle at the same time, and automatically cutting the enameled wire.

[0076] On the other hand, an embodiment of the present application further provides a method for using the multi-layer winding device described above, comprising the following steps:

[0077] S1: Fixing the fixed column 301, by extending the hydraulic rod 503 so that the three positioning blocks 504 fix the fixed column 301;

[0078] S2: Winding the inner layer of the double-layer enameled wire. Pass one end of the enameled wire through the guide hole 705 and fix it to the surface of the fixed column 301 with the hexagonal bolt 3032. At the same time, manually press the enameled wire into the first spiral guide groove 302 and start the drive motor 502 to drive the fixed column 301 to rotate, so that the wire is automatically wound on the surface of the fixed column 301.

[0079] S3: Wind the outer layer of the double-layer enameled wire, start the rotating motor 602 to drive the sleeve 401 to be sleeved on the surface of the fixed column 301, then start the driving motor 502 to drive the fixed column 301 and the sleeve 401 to rotate, and press the enameled wire into the second spiral guide groove 402 on the sleeve 401 to achieve the purpose of automatically winding the wire on the surface of the sleeve 401, and cut the enameled wire.

[0080] Working principle:

[0081] When winding the inner layer of the double-layer enameled wire, first pass one end of the enameled wire through the guide hole 705 on the movable plate 704, and place one end of the enameled wire into the L-shaped plate 3031, and use a wrench to tighten the hexagonal bolt 3032 to fix one end of the enameled wire. Then, press the enameled wire into the first spiral guide groove 302, and start the driving motor 502. The rotation of the driving motor 502 drives the active gear plate 506 to rotate, and the rotation of the active gear plate 506 drives the driven gear ring 508 and the connecting tube 507 to rotate. The rotation of the connecting tube 507 drives the concave rotating disk 501 to rotate, and the rotation of the concave rotating disk 501 drives the fixed column 301 to rotate. The rotation of the fixed column 301 enables the enameled wire to be wound around the inner wall of the first spiral guide groove 302, that is, the inner layer of the double-layer enameled wire is wound. At the same time, in the process of driving the rotating shaft 505 to rotate by the rotation of the driving motor 502, the reciprocating screw 706 can be driven to rotate under the action of the two transmission wheels 707 and the transmission belt 708. The rotation of the reciprocating screw 706 drives the slider 702 to move. The movement of the slider 702 drives the moving plate 704 to move through the L-shaped rod 703. The movement of the moving plate 704 drives the enameled wire passing through the guide hole 705 to automatically move, thereby making it easier for the enameled wire to be wound on the surface of the fixed column 301.

[0082] When winding the outer layer of the double-layer enameled wire, start the rotating motor 602. The rotation of the rotating motor 602 drives the threaded column 601 to rotate. The rotation of the threaded column 601 drives the Z-shaped plate 603 to move, thereby driving the sleeve 401 to move horizontally and sleeved on the outer surface of the fixed column 301. In the process of movement of the sleeve 401, the end of the enameled wire after the inner layer is wound can enter the interior of the strip-shaped opening 404. At this time, start the driving motor 502 again to drive the fixed column 301 to rotate. The rotation of the fixed column 301 drives the sleeve 401 to rotate under the action of the two limit columns 304, thereby realizing the outer layer winding of the double-layer enameled wire from right to left. At the same time, the rotation of the driving motor 502 drives the rotating shaft 505 to rotate. During the movement, the reciprocating screw 706 can be driven to rotate under the action of the two transmission wheels 707 and the transmission belt 708. The rotation of the reciprocating screw 706 drives the slider 702 to move. The movement of the slider 702 drives the movable plate 704 to move through the L-shaped rod 703. The movement of the movable plate 704 drives the enameled wire passing through the guide hole 705 to move automatically, so that it is more convenient for the enameled wire to be wound on the surface of the sleeve 401. After the winding is completed, the servo motor 802 is started, and the rotation of the servo motor 802 drives the bidirectional screw 801 to rotate. The rotation of the bidirectional screw 801 drives the two rectangular blocks 803 to move toward the middle at the same time, thereby driving the two cutters 804 to move toward the middle at the same time, and automatically cutting the enameled wire.

[0083] The above describes an embodiment of this specific implementation method, but this embodiment is not limited to the above specific implementation method. The above specific implementation method is merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
