[0045] like Figure 10 , Figures 14 to 16 As shown, the heating mechanism 9 is composed of a sliding frame 901, an eighth sliding hole 902, a fourth sliding rod 903, a heating half-circle 904, a heating rod 905, a second spring 906, a connecting plate 907, a fixing rod 908, and a ninth sliding hole 909.

[0046] The heating mechanism 9 comprises: sliding frames 901 slidably connected to both sides of the second support plate 702 in a vertical direction; and ninth sliding holes 909 slidably connected to the sliding frames 901 in a vertical direction on both sides of the second support plate 702.

At the bottom of each heating half-circle 904, there are multiple heating rods 905 that heat the coils 8 on the stator core 2 of the motor.

[0047] The working principle of this embodiment is as follows: The motor stator core 2 is placed on the movable support 5, and multiple positioning plates 411 are located inside the holes of the motor stator core 2. The handle 10 is pulled manually, and the movable support 5 slides horizontally on the guide rod 11 to be located directly below the shaping mechanism 7. The positioning mechanism 4 positions the motor stator core 2, and the locking mechanism 3 locks the movable support 5 in position to facilitate the subsequent shaping of the coil 8 on the motor stator core 2. The heating mechanism 9 heats the coil 8, and the shaping mechanism 7 shapes the multi-turn coil 8 on the motor stator core 2.

[0048] The positioning mechanism 4 positions the motor stator core 2 as follows: the output shaft of the second motor 416 drives the rotating shaft 404 and the turntable 414 to rotate. The rotating shaft 404 rotates on the base plate of the movable support 5. During the rotation of the turntable 414, the multiple third sliding holes 412 on the turntable 414 are slidably connected to the second sliding rod 413, thereby driving the second sliding rod 413 to slide in the third sliding hole 412. At the same time, the second sliding rod 413 slides in the fourth sliding hole 415 of the base plate 403 and slides in the fifth sliding hole 419 of the first connecting plate 420. The second sliding rod 413 drives the second slider 401 to slide in the second sliding hole 402 of the top plate 405. The second slider 401 drives the positioning plate 411 to move through the connecting rod 418. The multiple positioning plates 411 move to contact the inner side wall of the hole of the motor stator core 2 and clamp and position the motor stator core 2.

[0049] The output shaft of the first motor 407 drives the connecting shaft 410 to rotate, and the connecting shaft 410 drives the gear 409 to rotate. The gear 409 meshes with the gear ring 406 for transmission. The gear ring 406 drives the top plate 405, the bottom plate 403, the rotating shaft 404, the turntable 414, the second slider 401, the second slide rod 413, the connecting rod 418, the positioning plate 411, and the motor stator core 2 to rotate on the movable support 5. This allows the position of the motor stator core 2 to be swung, which facilitates the subsequent shaping of the multi-turn coil 8 on the motor stator core 2.

[0050] The locking mechanism 3 locks the movable support 5 as follows: the output end of the first electric cylinder 301 drives the first slider 302 to slide horizontally inside the support frame 6, the first slide rod 303 slides in the first slide hole 304 of the side plate of the first slider 302 in the inclined direction, the first slide rod 303 drives the locking block 305 to move, and the groove of the locking block 305 moves to engage with the bottom of the locking block 306 to lock the position of the movable support 5.

[0051] The heating mechanism 9 heats the coil 8, and the shaping mechanism 7 shapes the multi-turn coil 8 on the motor stator core 2 as follows: the output end of the second electric cylinder 701 drives all parts on the second support plate 702 to move downwards in the vertical direction; the multiple shaping plates 714 of the shaping mechanism 7 move to the outer circumference of the motor stator core 2; the shaping disk 717 abuts against the top of the coil 8 of the motor stator core 2; the movable support 5 abuts against the bottom of the coil 8 of the motor stator core 2; and the output end of the third electric cylinder 718 drives... The top cover 705 moves vertically inside the fixing ring 710. The inner wall of the circumferential inclined surface 704 of the top cover 705 moves to slide against multiple abutting rollers 708. The abutting rollers 708 drive the third slide rod 709 to slide on the sixth slide hole 713 of the second connecting plate 712. At the same time, the third slide rod 709 drives the fourth slider 719 to slide on the seventh slide hole 715 of the shaping plate 717. The fourth slider 719 drives the shaping plate 714 to move into the insertion hole on the outer circumference of the motor stator core 2 to shape the coil 8.
