A groove is provided on the lower side of the pin 310, and a steel ball in the pin seat 305 is engaged in the groove to fix the contour gripping plate 303. When the gripping cylinder 308 retracts, it causes the pin 310 to press down, and the pin 310 is inserted into the pin seat 305. The steel ball in the pin seat 305 cooperates with the groove on the pin 310 to fix the contour gripping plate 303. When the gripping cylinder 308 extends, the pin 310 separates from the pin seat 305, and the contour gripping plate 303 automatically falls off, so as to realize the quick replacement of the contour gripping plate 303, thereby adapting to bra side wings of different sizes.

[0044] A camera 15 is mounted on the frame 1 above the second feeding plate 20. The camera 15 captures images of the bra side wings on the second feeding plate 20 and transmits the captured images to the system.

The piston rod of the second cylinder 710 is rotatably connected to the rear end of the scissor connecting block 709. A scissor assembly is mounted on the scissor connecting block 709, which includes two cutters 711 and a scissor cylinder 712 that drives the two cutters 711 to approach each other to cut the webbing.

[0056] The receiving mechanism includes a receiving box 810 and a receiving mounting plate 801 mounted on the frame 1. Two horizontal first receiving guide rods 802 are mounted on the receiving mounting plate 801, and a first receiving connecting plate 803 is slidably mounted on each of the first receiving guide rods 802. A third rodless cylinder 804 is mounted on the receiving mounting plate 801 to drive the first receiving connecting plate 803 to move back and forth between the receiving position on the production line and the receiving box. Two vertical second receiving guide rods 805 are mounted on the first receiving connecting plate 803, and a second receiving connecting plate 806 is connected to the lower ends of the two second receiving guide rods 805. A receiving cylinder 807 is mounted on the first receiving connecting plate 803 to drive the second receiving connecting plate 806 to move up and down. The second receiving connecting plate 806 is equipped with a second gripper on each side for gripping the side wings of the bra. The second gripper includes two second clamping plates 808 and a second gripper cylinder 809 that drives the two second clamping plates 808 to cooperate and clamp the side wings of the bra.

[0057] During operation, the first lifting cylinder 212 and the second lifting cylinder 213 drive the first gripper to move downwards, each gripper grasping one bra side wing. The first lifting cylinders 212 and 213 then drive the first gripper to move upwards, lifting the bra side wing. The feeding motor 207 drives the first gripper to move above the second feeding plate 20. The first lifting cylinders 212 and 213 then drive the first gripper downwards, releasing the gripper and placing the two bra side wings onto the second feeding plate 20.

[0058] Subsequently, camera 15 captures images of the bra side wings on the second feeding plate 20, and the system identifies and determines the position information of the bra side wings on the second feeding plate 20. The system controls the robotic arm 301 to drive the gripping mounting plate 307 to move downward, which in turn drives the contour gripping plate 303 to move downward, aligning the suction hole 304 on the contour gripping plate 303 with the bra side wings to hold them in place. The robotic arm 301 then places the two bra side wings on the second feeding plate 20 together into the template assembly at the material position on the production line. Then, the third lifting cylinder 408 and the second rodless cylinder 415 drive the second pick-and-place connecting plate 409 to move onto the template assembly at the material position on the production line. The two first cylinders 414 drive the insertion rod 413 to be pulled out from the positioning hole on the handle 14 to release the upper frame 10. The upper frame 10 and the base plate 11 are attracted by magnets to clamp the two overlapping bra side wings. Subsequently, the second pick-and-place connecting plate 409 is reset, the first conveyor belt 16 transports the template assembly, and the blocking component will block the template assembly at the sewing material loading position.

[0059] The first pusher assembly pushes the template assembly of the sewing feed position onto the worktable 18. X and Y motors 502 drive the locking assembly to move to the template assembly, causing the positioning pin 13 on the template assembly to engage in the notch, thus securing the template assembly. Subsequently, X and Y motors 502 drive the template assembly to the sewing machine head 9. Presser foot cylinder 601 drives presser foot 606 downwards into the template sewing groove 12 of the template assembly, pressing the webbing above the bra side wing. Then, the system controls X and Y motors 502 to drive the template assembly to move. The sewing machine head 9 works to sew the webbing and bra side wing. The template assembly pushes presser foot 606 in the X direction, causing the webbing to move back and forth in the X direction, creating a "W" shaped stitch on the webbing. After sewing is complete, the second cylinder 710 drives the scissor assembly downwards along the guide groove 706, cutting the webbing.

[0060] X and Y motors 502 deliver the template assembly to the first lifting assembly. The first lifting assembly and the second pushing assembly deliver the sewn template assembly to the second conveyor belt 17. The second conveyor belt 17 transports the template assembly. Subsequently, the third pushing assembly, the second lifting assembly, and the fourth pushing assembly work in sequence to deliver the template assembly to the receiving position of the production line. The blocking assembly will block the template assembly at the receiving position of the production line. Then, the first rodless cylinder 404 drives the connecting seat 403 to move above the receiving position of the production line. The third lifting cylinder 408 and the second rodless cylinder 415 drive the second pick-and-place connecting plate 409 to move to the template assembly. The two first cylinders 414 drive the insertion rod 413 to insert into the positioning hole on the handle 14 to fix the upper frame 10. The second pick-and-place connecting plate 409 resets and removes the upper frame 10 from the base plate 11. Finally, the receiving cylinder 807 drives the second gripper to move downwards, clamping the sewn bra side wing. The receiving cylinder 807 then drives the second gripper to reset, removing the sewn bra side wing. The third rodless cylinder 804 drives the first gripper to move, sending the sewn bra side wing into the receiving box 810. The first conveyor belt 16 transports the base plate 11 to the material position on the assembly line, where the blocking component will block the template component at the material position on the assembly line.
