As described above, the winding mechanism repeatedly winds each set of the next following slots until the last set of slots of the straight stator core 6 is wound, then the winding mechanism 4 stops winding, the clamp pressing cylinder 274 drives the pressing block 275 to rise, then the left and right feeding servo motors 23 drive the straight stator core 6 to move to the right, at the same time, the clamp rotating servo motor 25 drives the straight stator core 6 to rotate to the front side of the frame 1, the translation servo motor 42 drives the winding needle to move to the left by the distance of one slot, the winding needle carries a copper wire to hang the wire, then the clamp rotating servo motor 25 drives the straight stator core 6 to rotate to the back side of the frame 1 to reset, the straight stator core 6 is kept vertical, the lifting servo motor drives the winding needle to rise to be flush with the stator core 6, and then the front and back feeding servo motors 21 drive the straight stator core 6 to slide forward by a distance, the straight stator core 6 is far away from the winding needles, and the copper wires between the straight stator core and the winding needles are elongated, so that the three winding needles 47 finally pull the copper wires to perform a wire hanging action.

After the wire is too good, the wire clamping and trimming mechanism 3 is started, then the wire clamping translation cylinder 32 drives the wire clamping translation seat 34 to slide forwards, then the wire trimming cutter lifting cylinder 33 drives the wire trimming lifting seat 363 to descend, the jacking spring 3611 is compressed, so that the wire clamping lifting slider 364 is separated from the wire clamping block 366, the wire clamping opening 367 is opened, and then the wire clamping lifting cylinder 31 drives the wire clamping lifting seat 35 to ascend to the same height of a copper wire and stop. At this time, the trimming knife 362 and the clipping block 366 are located between the straight stator core 6 and the winding needle, then the translation servo motor 42 drives the winding needle to slide to the right, the left and right feeding servo motor 23 also drives the straight stator core 6 to move to the right, so that the copper wires between the straight stator core 6 and the winding needle 47 are hung at the clipping opening 367, the three copper wires are respectively hung at the clipping openings 367 of the three clipping and trimming assemblies 36, then the trimming knife lifting cylinder 33 drives the trimming lifting seat 363 to ascend, the lifting spring 3611 is restored and lifts the clipping lifting slide 364, the three clipping lifting slides 364 push the trimming lifting seat 363 and the three trimming knives 362 to ascend together, the clipping lifting slide 364 and the clipping block 366 clip the copper wires at the clipping opening 367 in advance, the clipping lifting slide stops ascending, then the trimming knife lifting cylinder 33 also drives the trimming lifting seat 363 and the three trimming knives 362 to ascend, the three trimming knives 362 and the trimming lifting seat 363 continue to ascend under the driving of the trimming knife lifting cylinder 33, when the trimming lifting seat 363 pushes the second jacking protrusion upwards to ascend together, the trimming lifting seat 363 and the trimming knives 362 stop ascending, the trimming lifting seat 363 pushes against the wire clamping lifting slide block 364, so that the wire clamping lifting slide block 364 keeps clamping the copper wires, and meanwhile, the three trimming knives 362 cut off the copper wires at the wire clamping opening 367.

After the wire is cut, the wire clamping translation cylinder 32 drives the wire clamping translation seat 34 to slide backwards, the wire shearing cutter lifting cylinder 33 drives the wire shearing cutter to descend, meanwhile, the lifting servo motor 43 drives the lifting sliding seat 45 to slide upwards, and the copper wire is stretched upwards, so that the copper wire is tensioned, and a certain length is reserved. Further, after the wire is cut, the other mechanisms are reset to prepare for winding of the next straight stator core 6.
