When the picking and placing mechanism 500 picks up and updates the stator core winding tooling 300 which is wound on the bearing mechanism 400 and is used for clamping the stator core winding tooling 300 which is not wound, the bearing mechanism 400 is withdrawn, the wire clamping and shearing mechanism 900 and the upper wire passing mechanism 700 move to the position corresponding to the winding machine 200 based on the first cylinder 720X direction, the second cylinder 721 is adjusted to enable the wire clamping and shearing mechanism 900 to reach the position corresponding to the winding machine 200 in the Y direction, the enameled wire extending out of the winding machine 200 is wound by the winding post 321 on the winding tooling 300 and then pulled to the wire clamping nozzle 736, the fourth cylinder 725 is adjusted, the wire shearing knife 734 drives the wire clamping sleeve 735 to shrink to the fourth cylinder 725 on the wire clamping and shearing guide rod 731 based on the fourth cylinder piston rod 732, the wire clamping nozzle leaks out, the enameled wire is wound on the wire clamping nozzle 736 and is wound out through the recess 737, the arrangement of the recess 737 enables the enameled wire to be wound more tightly, the fourth cylinder 725 reversely moves, the wire clamping knife 734 drives the wire clamping sleeve 735 to clamp the wire clamping nozzle 731 based on the fourth cylinder piston rod 732 736 direction moves, the enameled wire is clamped on the winding nozzle 736, redundant enameled wire is cut off by the wire cutting knife 734, automatic winding is started, when top wire passing is carried out on the enameled wire provided with the wire pressing terminal 316 along the anticlockwise direction, the first wire hanging column 744 of the upper wire passing mechanism 700 is one, the third cylinder 722 and the second Z-direction lifting cylinder 714 fall to a gap 312-2(B) between the upper wire blocking column 314 and the upper wire blocking plate 315 on the top of the iron core 313 in the enameled wire, the outer surface of the first wire hanging column 744 is flush with the root tangent line of the wire pressing terminal 316, the pulling force generated on the wire pressing terminal 316 when the enameled wire is wound on the wire pressing terminal 316 is dispersed, and the wire pressing terminal 316 is prevented from deforming during winding; when the top line of the coil provided with the line pressing terminal 316 is passed along the clockwise direction, the first line hanging column 744 of the upper line passing mechanism 700 is one, and the third cylinder 722 and the second Z-direction lifting cylinder 714 fall to a gap 312-2(a) between the upper line blocking column 314 and the upper line blocking plate 315 on the top of the coil inner iron core 313, and the outer surface of the first line hanging column 744 is flush with the root tangent line of the line pressing terminal 316; when the top of a coil provided with the wire pressing terminal 316 is used for threading in clockwise and counterclockwise directions, two first wire hanging columns 744 of the upper thread threading mechanism 700 are provided, one is used for forward winding and the other is used for reverse winding, and the distance between the two first wire hanging mounting columns 744 is an integral multiple of the gaps 312-2(A) and 312-2 (B). Since the second hanging wire mounting plate 742 is detachably connected to the first hanging wire mounting plate 741, the number of the first hanging wire mounting posts 744 is selected according to different stator cores and winding manners.

The lower wire passing mechanism 800 is located on one side of the bearing mechanism 400 close to the iron core 310 and comprises a fixed seat 810 installed on the rack 100, a fifth cylinder 820 moving along the Z direction, a third wire hanging mounting plate 830, a wire hanging column base 840 and a second wire hanging column 850, wherein the fixed seat 810 is provided with the fifth cylinder 820, the fifth cylinder 820 is connected with the third wire hanging mounting plate 830 in a sliding manner along the Z direction, the top of the third wire hanging mounting plate 830 is detachably connected with the wire hanging column base 840, and the top of the wire hanging column base 840 is provided with two second wire hanging columns 850 along the Z direction.

The first cylinder 720, the second cylinder 721, the third cylinder 722 and the fifth cylinder 820 are sliding table cylinders.

When the bottom of the coil passes through the line, the lower line passing mechanism 800 operates, the two second line hanging columns 850 rise to the gap 312-3 formed among the second line blocking plate 317, the third line blocking plate 319 and the lower line blocking column 318 which are close to each other at the bottoms of the two coil inner cores 313 to be wound after the winding is completed and the line passes through the bottom based on the fifth cylinder 820, the electric wire is ensured to fall into the gap among the second line blocking plate 317, the third line blocking plate 319 and the lower line blocking column 318 when the line passes through the bottom, and the accuracy of the winding is ensured.

The present invention has been described above by way of example, but the present invention is not limited to the above-described specific embodiments, and any modification or variation made based on the present invention is within the scope of the present invention as claimed.
