In the stator assembly, an insulating coating is added to the outside of the copper wire to make enameled wire, which is then connected end to end to form a winding. Flat wire winding is one of the winding forms. Because its single enameled wire is shaped like a hairpin, it is also commonly known as a hairpin motor.

In addition, since the shape of the flat wire of the stator of the hairpin motor is relatively flat, the original twisting limit structure is used for more clamping contact with the curved surface, which increases the difficulty of the flat wire contact position. At the same time, the angle deviation of the flat wire increases after the twisting operation. Summary of the invention

The opening set at the top of the positioning platform 1 is used to assist the displacement of the guide frame 1 2 and the guide frame 2 10, so as to facilitate the limiting of the stator winding of the hairpin motor with different depths.

Figure 1-3 As shown, the output end of the stepping motor 11 is provided with a plate structure connected to the gear ring 15;

[0046] Flat wire twist assembly includes:

[0047] A guide cover plate 13 is installed at the opening of the limit box 12, and holes are provided on both sides of the guide cover plate 13 to engage with the guide rod 9;

[0048] The guide holes 14 are arranged in an annular shape and equidistantly on the surface of the guide cover plate 13, and the guide holes 14 are aligned with the cable harness groove 8. The guide holes 14 are arranged in parallel with the U-shaped opening clamp of the twist clamp 17, and the twist clamp 17 is composed of the U-shaped opening clamp and the vertically installed rod body to form an L-shaped structure;

[0049] The gear ring 15 is rotatably connected to the inner wall of the limit box 12, and the gear ring 15 is an annular structure, and the gear ring 15 is connected to the rod body at the output end of the stepping motor 11;

[0050] The outer wall of the swivel 16 is rotatably connected to the inner wall of the gear ring 15 through a ball bearing, and the side wall of the swivel 16 is rotatably connected to the inner wall of the limit box 12. The surface of the swivel 16 is equidistantly provided with fan-shaped opening grooves, and the fan-shaped opening grooves of the swivel 16 are in contact with the rod body of the twist head clamp 17, and the U-shaped opening clamp direction of the twist head clamp 17 is horizontally arranged with the installation direction of the gear rod 18;

[0051] The twist head clamp 17 is equidistantly connected to the inner wall of the limit box 12 through a rod, and one end of the twist head clamp 17 is provided with a protrusion structure that abuts against the groove surface of the swivel 16;

[0052] The gear rod 18 is mounted on the surface of the rod body connecting the torsion clamp 17 and the limit box 12, and the gear rod 18 is rotationally connected with the gear ring 15 in the form of a bevel gear;

[0053] The limit clamp 19 is symmetrically arranged on the inner wall surface of the U-shaped opening clamp of the twisting head clamp 17, and the limit clamp 19 is composed of a rectangular plate body and a spring rod. The spring rod of the limit clamp 19 is installed in the inner cavity of the U-shaped opening clamp of the twisting head clamp 17, and the spring rod of the limit clamp 19 is a rod body structure with a double-layer sliding connection, and the bottom end of the spring rod of the limit clamp 19 is provided with a delay electric signal switch electrically connected to the stepping motor 11;

[0054] In conjunction with the accompanying drawings Figure 1-7 As shown, the guide cover plate 13 is engaged with the limit box 12, and the guide hole 14 arranged on the surface of the guide cover plate 13 cooperates with the wire groove 8 on the surface of the wire harness plate 7 to comb and guide the flat wire of the stator winding of the card-issuing motor. After the flat wire enters the limit box 12, the flat wire is inserted into the U-shaped opening clamp of the twisting clamp 17. The limit clamp 19 located inside the U-shaped opening clamp, as shown in FIG. Figure 6 As shown, as the spring rod of the double-layer rod body of the limit clamp 19 is inserted into the twist clamp 17 along with the flat wire, the double-layer rod body of the limit clamp 19 is converged and docked with the delayed electric signal switch at the rear end. After the flat wire is completely inserted into the U-shaped opening clamp of the twist clamp 17, the delayed electric signal switch contacted by the limit clamp 19 starts the output end of the stepper motor 11 to rotate, wherein the stepper motor 11 is connected to the gear ring 15, as shown in FIG. Figure 5As shown, as the gear ring 15 rotates at an angle between 0° and 80°, the gear rod 18 connected to the bevel gear makes a complete rotation. Since the gear rod 18 has a small diameter and a limited rotation length on the surface of the gear ring 15, the gear ring 15 does not need to rotate a complete circle. At this time, the gear rod 18 drives the twist head clamp 17 to rotate, so that the rod body structure on one side of the twist head clamp 17 rotates out of the fan-shaped opening groove of the swivel 16. At the same time, the flat wire inside the twist head clamp 17 twists under the stable clamping of the limit clamp 19, wherein the swivel 16 is provided with a connected rod body near the limit box 12, and the connecting rod body is stably arranged with the stepping motor 11 and the rotation position of the gear ring 15, so that the swivel 16 and the gear ring 15 are stably connected in rotation.

[0055] Working principle: When the flat wire card-issuing motor stator automatic twisting machine is used, the limiting ring 3 sliding inside the guide frame 2 is installed with the card-issuing motor stator. As the flat wire of the card-issuing motor stator passes through the wire harness groove 8 inside the wire harness plate 7, after the card-issuing motor stator and the limiting ring 3 slide, the card-issuing motor stator and the surface of the wire harness plate 7 are abutted, so that the migration frame 6 on the side wall of the wire harness plate 7 is extended along the installation position of the positioning ring 2 5, so that the guide rod 9 provided on the migration frame 6 enters the openings on both sides of the guide cover plate 13, and at the same time, the guide hole 14 located inside the guide cover plate 13 is used to converge the flat wire position of the card-issuing motor stator. As the flat wire of the card-issuing motor stator is inserted into the U-shaped opening frame of the twisting clamp 17, and as the flat wire of the card-issuing motor stator is stably inserted into the twisting clamp 17, the twisting clamp 17 clamps the card-issuing motor. The flat wire of the stator, and at the same time, the spring rods of the limit clamp 19 are squeezed on both sides of the flat wire, so that the spring rods of the limit clamp 19 are in contact with the delayed electrical signal switch of the stepper motor 11, so that the stepper motor 11 starts after waiting for a period of time, and drives the gear ring 15 inside the limit box 12 to rotate. Since the stepper motor 11 and the limit box 12 are rotationally connected, the limit box 12 is not driven to rotate, and the gear ring 15 is connected to the bevel gear of the gear rod 18, so that the gear rod 18 drives the twisting clamp 17 to rotate, so that the flat wire of the stator of the card-hairing motor located inside the U-shaped opening clamp of the twisting clamp 17 automatically twists its head under the external force bias rotation. Since the multiple gear rods 18 connected to the gear ring 15 rotate simultaneously and in the same direction, the twisting angle deviation of the flat wire of the stator of the card-hairing motor driven by the gear rod 18 is reduced, thereby increasing the overall practicality.
