Figure 5The present invention is a schematic diagram of the structure of the expanding mechanism 400 in the expanding device for the flat copper wire of the flat wire motor stator in the embodiment of the utility model. The present embodiment provides a expanding device for the flat copper wire of the flat wire motor stator, including a base frame mechanism 100; a rotating carrier mechanism 200, which is arranged on the base frame mechanism 100 and has a carrier 210 for positioning the flat wire motor stator 510, and a rotating drive component that can drive the product in the carrier 210 to rotate; a guide mechanism 300, which is arranged on the base frame mechanism 100 and has a guide mechanism 300 for inserting the flat wire motor stator 510 10, and a guide tooth 310 for separating the gaps between the flat copper wires on the frame mechanism 10, and a first linear drive component 330 capable of driving the guide tooth 310 to move, and the carrier 210 is located on the moving path of the guide tooth 310; and a flaring mechanism 400, which is arranged on the base frame mechanism 100 and has a flaring jaw 410 for separating the multiple layers of flat copper wires on the stator 510 of the flat wire motor, and a second linear drive component capable of driving the flaring jaw 410 to move, and the carrier 210 is located on the moving path of the flaring jaw 410.

[0036] Since the rotating carrier mechanism 200, the guiding mechanism 300 and the expanding mechanism 400 are all arranged on the base frame mechanism 100, the rotating carrier mechanism 200, the guiding mechanism 300 and the expanding mechanism 400 are independent of each other and do not interfere with each other in function; since the rotating carrier mechanism 200 includes a carrier 210 arranged on the base frame mechanism 100, which has a positioning flat wire motor stator 510, and a rotating drive component that can drive the product in the carrier 210 to rotate, Therefore, the rotating carrier mechanism 200 can carry, clamp and drive the flat wire motor stator 510 to rotate. After a group of flat copper wires 520 to be separated are separated at the flaring station, the flat wire motor stator 510 can be rotated to rotate the next group of flat copper wires 520 to the flaring station.

Therefore, compared with the expanding device of the flat wire motor stator flat copper wire in which the rotating carrier mechanism 200, the guiding mechanism 300 and the expanding mechanism 400 are cross-arranged with each other, the structure can be simplified.

[0042] The positioning assembly further includes an inner support mold 222 that cooperates with the inner wall of the stator of the flat wire motor to limit the stator of the flat wire motor from rotating relative to the carrier 210 .

[0043] The rotating carrier mechanism 200 further includes an origin sensor 230 . The origin sensor 230 is disposed on the turntable frame 242 .

[0044] In this embodiment, the rotation axis of the rotating platform 243 is vertically arranged.

After fixing the current position, the program controls the expansion mechanism 400 to move, the transverse module 420 moves forward, and the lifting module 430 descends. After the expansion claw 410 guides the corresponding flat copper wire 520 to the corresponding position, the flat copper wire 520 of the current stator slot is expanded in turn. After the expansion of the single-slot flat copper wire 520 is completed, the above-mentioned expansion action is repeated to complete the expansion of the entire stator flat copper wire 520.
