[0002] In wet processing techniques such as leather and textile manufacturing, leather or fabric needs to be suspended on a conveying mechanism by hanging pins to complete processing steps such as disinfection and drying. Existing leather hanging pin operations rely on manual operation, which has the following drawbacks: manual hanging pins are inefficient and are affected by the operator's skill level, making it easy for the hanging pin position to shift. During the conveying process, the vibration of the hanging pins can easily cause the leather to slip off. Therefore, this application provides an automatic hanging pin device for wet processing.

Furthermore, the material platform 300 is equipped with a ring-shaped enclosure net 310; The lifting box 400 has an opening facing downwards and is mounted on the crossbeam plate 110 and located between two side walls. Furthermore, vertical threaded rods 430 are rotatably provided on the two side walls of the crossbeam plate 110, and gears 440 are respectively provided at the ends of the two threaded rods 430. The two gears 440 are connected by a transmission belt 450. A drive motor 431 is provided on one side of the crossbeam plate 110. The output end of the drive motor 431 is fixedly connected to the rotating shaft of the corresponding threaded rod 430. Threaded sleeves 420 are respectively threadedly connected to the two threaded rods 430. Connecting plates 410 are respectively fixedly connected to the two threaded sleeves 420. The two connecting plates 410 are respectively fixedly connected to the two ends of the lifting box 400. The feeding plate 500 is L-shaped, and its vertical plate body is longitudinally movable within the lifting box 400. Furthermore, the lifting box 400 is provided with a second ball screw module 510 and a second guide rod 520. The second guide rod 520 slides through the vertical plate of the feeding plate 500, and the ball screw of the second ball screw module 510 is threadedly connected to the vertical plate of the feeding plate 500. The positioning plate 600 is U-shaped, with its front upper surface located at the rear end of the lower surface of the horizontal plate of the feeding plate 500. Rotating grooves 610 are provided at corresponding positions on the two opposite side walls of the positioning plate 600. The support plate 620 is disposed between the two side walls of the positioning plate 600; The CCD industrial camera 730 is mounted on the lower surface of the support plate 620; Two rotating plates 710 are rotatably disposed within two rotating slots 610; Furthermore, the support plate 620 is provided with a first vertical plate 621 at the position corresponding to the two rotating slots 610, and a cylinder 720 is rotatably connected to the two first vertical plates 621 respectively. The piston end of the cylinder 720 is rotatably connected to the two rotating plates 710. Two suction cups 700 are fixedly connected to one end of the two rotating plates 710 extending out of the rotating groove 610, and are used to grip the leather; Two rotating columns 810 are rotatably mounted at the front and rear ends of the support plate 620, respectively. Furthermore, two second vertical plates 622 are respectively provided on the support plate 620 at the position corresponding to the rotating column 810. One of the second vertical plates 622 is provided with a servo motor 820. The rotating column 810 is rotatably connected to the two second vertical plates 622, and the output end of the servo motor 820 is connected to the rotating shaft of the rotating column 810. Two claw rods 800 are respectively set on two rotating columns 810 at one end to support the leather upward so that the leather between the two suction cups 700 will not fall downward when the suction cups 700 rotate.

[0025] This embodiment is implemented as follows: In use, stacked leather is placed on the material table 300. A CCD industrial camera 730 takes a picture of the leather to determine its position. Then, the first ball screw module 210 drives the moving plate 200 along the first guide rod 220, moving the leather directly below the CCD industrial camera 730. The drive motor 431 then drives the threaded rod 430 to rotate, causing the threaded rod 430 to drive the gear 440 to rotate. Through the transmission of the conveyor belt 450, the other threaded rod 430 rotates synchronously, causing the threaded sleeves 420 on both threaded rods 430 to move vertically. The threaded sleeves 420 drive the lifting box 400 on the connecting plate 410 to move downwards, bringing the suction cup 700 into contact with the leather. The suction cup 700 then holds the leather, and the lifting box 400 returns to its original position. Finally, the servo motor 820 drives the rotating column 810 to rotate, causing... The rotating column 810 drives the claw bar 800 to rotate, enabling the claw bar 800 to support the leather upwards, preventing the leather between the two suction cups 700 from falling downwards. Then, the second ball screw module 510 drives the feeding plate 500 to move backwards along the guide rod 520, causing the feeding plate 500 to move the positioning plate 600 backwards, thereby moving the leather backwards until it is directly above the hanging pin. Then, the claw bar 800 returns to its original position, and the cylinder 720 is activated, driving the rotating plate 710 to rotate. This causes the suction cups 700 on the rotating plate 720 to rotate with the rotating plate 710, bringing the two suction cups 700 closer together. When a set angle is reached, the suction cups 700 release the leather, allowing the leather to hang on the hanging pin. This ensures that the leather hangs on the hanging pin closer to the center, effectively improving the accuracy of the hanging pin and saving a significant amount of labor costs.

[0026] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the protection scope of the present invention.
