[0003] In motor manufacturing, the coil needs to be assembled into the stator core. The coil is mainly assembled with the stator core by winding. At present, many motor manufacturers still need a lot of manual assembly and production. For the current processing flow, most of the time, the copper wire is wound on the base mold to form a coil by manpower, and then the wound coil is removed and moved to the slot embedding equipment to embed the coil into the slot of the stator core. Two devices are required to perform the winding and embedding work respectively. The coil transfer consumes physical strength and time, is relatively cumbersome, and has low processing efficiency.

Only one device is needed to realize the winding and embedding functions, thereby reducing time consumption and improving processing efficiency.

[0014] The beneficial effects of the utility model are:

[0015] The utility model cooperates with the winding mechanism and the embedding mechanism to embed the coil into the slot of the stator core after the coil is wound.

[0016] The vertical column of the utility model is hinged on the bottom plate and can realize the verticality of the vertical column by cooperating with the elastic member and the limit block. Before the stator core is sleeved and fixed on the core positioning ring, the vertical column is rotated so that its alignment plate is received in the notch of the core positioning ring to facilitate the placement of the stator core. After the stator core is placed, the vertical column is loosened, and the alignment plate on the vertical column can be abutted against the inner wall of the stator core by the elastic member to achieve fixation.

[0017] The front end of the pusher of the utility model is provided with an inclined surface, and the inclined surface gradually becomes a vertical state when the second moving component drives the pusher to rotate, so as to push out the coil on the base mold.

[0018] The utility model adopts a second telescopic rod to drive the cross bar to rotate, and then drives the connecting rod and the push knife to rotate, and the linkage is smooth. If the cross bar is rotated by manpower, the physical strength is greatly consumed, and the coil may be wound on the base mold relatively tightly, and it is difficult to push the coil out by manpower alone, and it is difficult to embed it into place. The embedding effect can be improved by driving with the second telescopic rod. BRIEF DESCRIPTION OF THE DRAWINGS
