[0058] The conveying mechanism 2 includes a conveying frame 201, and two track plates 202 arranged on the conveying frame 201 and the first mounting plate 101. The two track plates 202 are arranged in parallel along the conveying direction. The plane where each track plate 202 is located is a vertical plane, and there is a certain distance between the two track plates 202. A row of rotatable rollers 203 is arranged on the inner side of each track plate 202 along the conveying direction. The two rows of rollers 203 on the two track plates 202 are located at the same height, and the stator core 100 can be supported on the two rows of rollers 203.

[0059] The conveying mechanism 2 further includes two rows of clips 204, the two rows of clips 204 correspond to each other, the corresponding clips 204 form a group, and the clips 204 of the same group can clamp the stator core 100 located on the roller 203. Each row of clips 204 is installed on the same linkage plate 205, and the linkage plates 205 of the two rows of clips 204 are connected. The linkage plate 205 can move back and forth along the conveying direction, and then clamp the stator core 100 through the clips 204, which can drive the stator core 100 to move in the conveying direction. The linkage plate 205 is driven by a linkage cylinder 206, and can also be driven by an electric cylinder.

[0060] The lifting mechanism 3 includes a rotating support plate 301 which is rotatably and movably arranged on the conveying path of the stator core 100, a plurality of lifting rods 302 which are arranged on the rotating support plate 301 and extend upward, and a first positioning rod 302 which is arranged on the upper end of the lifting rod 302.

After the stator core 100 is moved into position, the rotating support plate 301 moves upward, the first positioning rod 302 is inserted into the through hole, and the lifting rod 302 pushes the stator core 100 to move upward to a predetermined position.

[0061] The rotating drive mechanism 4 includes a rotating wheel 401 rotatably arranged on the lower surface of the second mounting plate 102. The rotating wheel 401 is a cylindrical structure, and the axis of the rotating wheel 401 is colinear with the rotation axis of the rotating support plate 301. A plurality of driving rods 403 extending up and down are arranged on the lower end surface of the rotating wheel 401, and a plurality of driving cylinders 303 are arranged on the upper surface of the rotating support plate 301. When the rotating support plate 301 moves upward, the lower end of the driving rod 403 can be inserted into the driving cylinder 303. When the rotating wheel 401 rotates, it can drive the rotating support plate 301 to rotate, and then drive the stator core 100 located thereon to rotate. The rotating wheel 401 is driven by a motor combined with a belt.

[0062] In order to prevent the rotating support plate 301 from rotating by itself when idle, a locking mechanism (not shown in the figure) can be provided. The locking mechanism can be a locking rod, which is provided below the rotating support plate 301 and can move up and down with the rotating support plate 301. A positioning hole can be provided on the rotating support plate 301. When the rotating support plate 301 needs to be locked, the locking rod is inserted into the positioning hole. When locking is not required, the locking rod is pulled out of the positioning hole. Of course, other locking methods can also be used in practice.

[0063] An operating hole 103 is provided on the second mounting plate 102 at a position corresponding to the rotating wheel 401 . When the stator core 100 is lifted up, its upper end is exposed from the operating hole 103 , so that the paper inserting mechanism 5 can insert paper into the stator core 100 .

[0064] The paper insertion mechanism 5 includes a paper storage box 501, a paper picking mechanism 52, a paper feeding mechanism 54, and a paper pushing mechanism 55 arranged on the upper surface of the second mounting plate 102. The paper storage box 501 is used to store paper 200 for paper insertion. The paper is rectangular, and the paper in the paper storage box 501 is stacked in the horizontal direction. An opening 502 is arranged on the side of the paper storage box 501 facing the paper picking mechanism 52. Two vertically extending levers 503 are arranged in the paper storage box 501 and at the position of the opening 502. The levers 503 are used to prevent the paper 200 from falling out of the opening 502 by itself. A mechanism for pushing the paper 200 toward the opening 502 is arranged in the paper storage box 501, so that the paper always rests against the levers 503.

[0065] The paper picking mechanism 52 includes a suction nozzle 523 disposed on the upper surface of the second mounting plate 102 and capable of moving along a first direction and a second direction, wherein the first direction is parallel to the horizontal direction in which the paper storage box 501 and the paper feeding mechanism 54 are arranged, and the second direction is a horizontal direction perpendicular to the first direction. The suction nozzle 523 extends along the second direction and the working end faces the paper storage box 501 and the paper feeding mechanism 54. When it is necessary to pick up paper, the suction nozzle 523 first moves along the first direction to a predetermined position so that it faces the opening 502 and is located between the two gear bars 503 when viewed along the second direction, and then the suction nozzle 523 moves toward the opening 502 along the second direction until the paper 200 is sucked, then retreats to a predetermined position, and then moves along the first direction to a position facing the paper feeding mechanism 54, and moves along the second direction to deliver the paper 200 to the paper feeding mechanism 54. The movement of the suction nozzle 523 along the first direction and the second direction are both realized by a linear module in the prior art.

[0066] The paper feeding mechanism 54 includes a paper feeding plate 541 that can move back and forth along the up and down direction and the second direction. When viewed from above, the paper feeding plate 541 is in an arc shape that opens toward one side of the suction nozzle 523. Curling edges 542 are provided on both sides of the paper feeding plate 541 along the first direction, and the curling edges 542 are formed on the side of the paper feeding plate 541 facing the suction nozzle 523. After the suction nozzle 523 takes paper from the paper storage box 501, it moves to a position facing the paper feeding plate 541 in the second direction. The suction nozzle 523 moves toward the paper feeding plate 541. When the suction nozzle 523 moves to a predetermined position, both sides of the paper 200 will be stuck in the curling edges 542 on the corresponding sides, and then the suction nozzle 523 releases the paper 200 and returns to take paper next time. After the paper 200 is fed to the paper feeding plate 541, the paper feeding plate 541 moves downward to the position of the stator core 100 that is lifted up. When viewed along the second direction, the paper feeding paper 541 is in a U-shape that opens downward, and a clearance gap is formed in the middle portion of the U-shape. Through the clearance gap, the paper pushing mechanism 55 can push the paper 200 on the paper feeding paper 541 into the wire slot of the stator core 100 .

[0067] There are two suction nozzles 523 , which are arranged one above the other to suck the two ends of the paper 200 .

[0068] The paper picking mechanism 52 further includes an arc block 524 , and each suction nozzle 523 corresponds to an arc block 524 . When viewed from above, the side of the arc block 524 facing the paper feeding paper 541 is arc-shaped, and the diameter of the arc matches the diameter of the arc of the paper feeding paper 541 . The positions of the arc block 524 and the suction nozzle 523 in the second direction are configured so that when the suction nozzle 523 takes paper from the paper storage box 501 and when the suction nozzle 523 contacts the paper 200, the arc block 524 is located on the side opposite to the paper 200 relative to the gear lever 503, that is, when the suction nozzle 523 is inserted to take paper, the arc block 524 does not enter the paper storage box 501 through the two gear levers 503, and when the suction nozzle 523 puts the paper 200 into the paper feeding paperboard 541, when both sides of the paper 200 contact the curling edge 542, the arc block 524 can push the paper 200 to continue to move toward the arc of the paper feeding paperboard 541 until both sides of the paper 200 enter the curling edge 542, that is, the function of the arc block 524 is to help the paper 200 enter the paper feeding paperboard 541.

[0069] The paper pushing mechanism 55 includes an L-shaped paper pushing rod 551 and a paper pushing board 552. The paper pushing rod 551 includes a vertical portion and a horizontal portion arranged at the upper end of the vertical portion. The vertical portion is inserted into the operation hole 103 and simultaneously inserted into the stator core 100 to be inserted with paper lifted by the lifting mechanism 3. The horizontal portion extends in a direction away from the paper feeding board 541, and the horizontal portion is connected to the output end of the driving cylinder. The paper pushing board 552 is arranged on the side of the vertical portion facing the paper feeding board 541. The paper pushing board 552 has multiple and vertically extended, and the multiple paper pushing boards 552 are arranged along the first direction. The multiple paper pushing boards 552 can be aligned with the corresponding wire grooves, and the thickness of the paper pushing board 552 is configured to be inserted into the corresponding wire grooves. When paper pushing is required, the paper pushing rod 552 moves in the direction of the paper feeding board 541, and the paper pushing board 552 pushes the paper 200 into the corresponding wire groove. The number of the paper pushers 552 is less than the number of the wire slots on the stator core 100 . By rotating the stator core 100 , the wire slots can be moved to the positions corresponding to the paper pushers 552 in sequence, and finally all the wire slots are inserted with paper.

[0070] Furthermore, the paper feeding paper 541 can move back and forth along the second direction. When the paper feeding paper 541 is not inserted into the stator core 100, the paper feeding paper 541 is moved along the second direction so as to have a certain distance from the inner wall of the stator core 100 as much as possible, so as to collide with the inner wall of the stator core 100 when inserted. After the paper feeding paper 541 moves downward into position, the paper feeding paper 541 moves toward the side where paper needs to be inserted, so that the distance between the paper and the offline slot is smaller. The up and down movement of the paper feeding paper 541 is driven by an electric cylinder, and the movement of the paper feeding paper 541 along the second direction is driven by a motor in combination with a lead screw.
