[0063] Under the drive of the turnover mechanism 522, the turnover platform 523 switches to the horizontal position or the vertical position;

[0064] When the turnover platform 523 is misaligned with the stroke space 504, the turnover mechanism 522 drives the turnover platform 523 to switch to the horizontal position, the operating surface 1902 faces downward, the placing surface 1901 faces upward, the skeleton transfer device 6 positions and places each insulation skeleton 242 on the placing surface 1901 of each skeleton press-fitting station 19, and the stator transfer device 4 positions and places the stator core 241 on the stator assembly station 513.

[0065] Then, the turnover mechanism 522 drives the turnover platform 523 to switch to the vertical position, and the design of the elastic positioning pin 23 on the skeleton placing clamp 191 avoids the insulation skeleton 242 from separating from the skeleton press-fitting station 19 during the turnover of the turnover platform 523. Under the drive of the assembly translation mechanism 511, the stator assembly station 513 moves to the side of the turnover platform 523 to make the turnover platform 523 in the vertical position enter the stroke space 504 until the skeleton press-fitting station 19 near the turnover mechanism 522 corresponds to the assembly advancing mechanism 514, the stator assembly station 513 is driven to rotate to the required position by the rotating mechanism 512, so that the core block 2401 of the stator core 241 corresponds to the advancing end of the assembly advancing mechanism 514, and the height position of the stator core 241 is adjusted by adjusting the height position of the lifting platform 15 in the Z-axis direction by the two lifting adjusting mechanisms 14, so as to ensure that the insulation skeleton 242 corresponds to the corresponding core block 2401, realize the automatic alignment of the core block 2401 and the insulation skeleton 242, and ensure the precise assembly of the corresponding core block 2401 and the insulation skeleton 242.

[0066] Then, the operation surface 1902 of the skeleton press-fitting station 19 is towards the assembly advancing mechanism 514, and the placement surface 1901 of the skeleton press-fitting station 19 is towards the stator assembly station 513, so that the assembly advancing mechanism 514 advances the corresponding skeleton press-fitting station 19 to overcome the elastic element 1904 to translate along the Y-axis direction, and the placement plate 192 drives the insulating skeleton 242 to separate from the skeleton placement clamp 191 and press-fits the insulating skeleton 242 on the corresponding core block 2401. At this time, the inner side wall of the operation plate 193 abuts against the limiting plate 503 to limit the operation plate 193, thereby ensuring the consistency of the translation stroke of each skeleton press-fitting station 19.

[0067] After the insulating skeleton 242 is assembled with the corresponding core block 2401, the assembly translation mechanism 511 drives the stator assembly station 513 to translate along the X-axis direction, so that the turnover platform 523 in the vertical position is in the stroke space 504 and the turnover platform 523 and the stator assembly station 513 are away from each other. The stator core 241 on the stator assembly station 513 sequentially passes through each skeleton press-fitting station 19. In this process, the rotating mechanism 512 drives the stator assembly station 513 to rotate to drive the stator core 241 to rotate, so that the core block 2401 which has not yet press-fitted with the insulating skeleton 242 corresponds to the next skeleton press-fitting station 19. The assembly advancing mechanism 514 performs the press-fitting work between the insulating skeleton 242 and the core block 2401, and sequentially circulates, thereby completing the assembly work of the stator assembly 24. After the assembly of the stator core 241 and each insulating skeleton 242 is completed, the assembly device 5 is reset to prepare for the next assembly of the stator core 241 and each insulating skeleton 242.

[0068] After the stator assembly 24 is completed, the assembly translation mechanism 511 moves the stator assembly 24 to the side of the finished product transfer device 8. The finished product transfer device 8 takes the stator assembly 24 from the assembly table 10 and loads it to the finished product loading position 2201. The finished product conveying belt 91 moves the finished product loading position 2201 out to discharge the finished product.

[0069] The automatic assembly machine has high automation degree, improves the assembly efficiency of the stator assembly 24, reduces the labor intensity of workers, ensures the quality and consistency of products, and is beneficial to realize mass production.

[0070] Of course, the above is only a typical example of the present application, in addition to this, the present application can have other various specific embodiments, and any technical solutions formed by equivalent replacement or equivalent transformation are within the scope of the present application.
