[0021] like Figures 1 to 5The image shows an embodiment of the present invention, relating to a clamping device for leather processing, comprising a device body 10. The device body 10 is used to clamp, lift, and convey the leather to be marked during the laser marking process. The device body 10 includes a clamping unit 20, a lifting unit 30, and a conveying unit 40. The clamping unit 20 includes a support plate 21, a base plate 22, and several clamping components 50. The support plate 21 is used to support the leather to be marked, and the upper surface of the base plate 22 is connected to the support plate 21. The several clamping components 50... The clamping unit 20 is evenly arranged around the edge of the bearing plate 21 to clamp and fix the leather to be marked. The lifting unit 30 is used to lift the leather after marking is completed. It includes a lifting plate 31 and a lifting drive assembly 60. The lifting drive assembly 60 is connected to the lifting plate 31 and is used to drive the lifting plate 31 to move up and down in the vertical direction. The conveying unit 40 is fixedly connected to the base plate 22 and is used to drive the base plate 22 to move in a preset direction after marking is completed, thereby driving the clamping unit 20 to move synchronously, so as to convey the marked leather to the unloading position. Specifically, by integrating the clamping, lifting and conveying units 40, the clamping, marking, lifting and conveying of leather laser marking is fully automated, which greatly reduces manual intervention and improves processing efficiency. The coordinated action of each unit ensures accurate positioning during leather marking, flat lifting after marking and controllable conveying, effectively improving the integrity and consistency of the laser marking pattern.

[0022] like Figure 2 As shown, each of the four corners of the lower surface of the support plate 21 is provided with a support foot 23. The support foot 23 is used to support the support plate 21, and its lower end is fixedly connected to the base plate 22. Specifically, the support feet 23 at the four corners of the lower surface of the support plate 21 provide stable support for the support plate 21, evenly distribute the load between the leather and the support plate 21, and prevent the support plate 21 from deforming; on the other hand, they form a space between the support plate 21 and the base plate 22, allowing sufficient stroke for the lifting unit 30 to operate, and ensuring the reliable realization of the lifting function.

[0023] like Figure 2 As shown, the support plate 21 has a clearance hole 24 in the middle; the lifting plate 31 is adapted to the clearance hole 24 and can pass through the clearance hole 24. Specifically, the clearance hole 24 in the middle of the support plate 21 is precisely adapted to the lifting plate 31, providing guidance for the lifting plate 31 to rise and fall, ensuring that it is stably inserted and lifts the leather, avoiding lifting deviation, ensuring that the leather is flat after being lifted, and facilitating the smooth unloading of the conveying unit 40.

[0024] like Figure 2As shown, there are ten clamping components 50, with six clamping components 50 evenly distributed at both ends of the length direction of the support plate 21 and four clamping components 50 evenly distributed at both ends of the width direction of the support plate 21. Specifically, the ten clamping components 50 are evenly arranged circumferentially along the edge of the support plate 21, clamping the leather at multiple points in the length and width directions, ensuring uniform force distribution, effectively preventing leather wrinkles or displacement during marking, significantly improving the clamping and fixing effect, and ensuring the accuracy of the laser marking pattern.

[0025] like Figure 3 As shown, the clamping assembly 50 includes a clamping cylinder 51, a pressure arm 52, and a connecting rod module 70. A piston rod 53 is connected to the output end of the clamping cylinder 51. One end of the pressure arm 52 is hinged to the piston rod 53, and the other end of the pressure arm 52 is connected to a soft pressure block 54. The connecting rod module 70 is hinged to the middle of the pressure arm 52. When the piston rod 53 extends or retracts, the pressure arm 52 rotates around its hinge point with the connecting rod module 70, thus clamping or releasing the leather. Specifically, the clamping assembly 50 uses a transmission structure of the clamping cylinder 51, pressure arm 52, and connecting rod module 70, combined with the soft pressure block 54, to achieve rapid response and stable transmission of the clamping action. The soft pressure block 54 avoids damage to the leather surface, increases friction, ensures reliable clamping, and can adapt to the clamping requirements of leathers of different thicknesses. In this embodiment, the soft pressure block 54 can be a rubber block or other existing mature soft material pressure blocks.

[0026] like Figure 3 As shown, the linkage module 70 includes two opposing connecting rods 71 ​​and a fixed seat 72. One end of each connecting rod 71 is hinged to both sides of the middle portion of the pressure arm 52, and the other end of each connecting rod 71 is hinged to both sides of the fixed seat 72. The fixed seat 72 is positioned above the clamping cylinder 51 and connected to the side of the bearing plate 21. Specifically, the two opposing connecting rods 71 ​​of the linkage module 70, together with the pressure arm 52 and the fixed seat 72, form a four-bar linkage structure, making the pressure arm 52 rotate more smoothly and the force more even, improving the mechanical strength and transmission accuracy of the clamping assembly 50, and further ensuring the stability of the leather clamping.

[0027] like Figure 4As shown, the lifting drive assembly 60 includes an abutment plate 61, a lifting cylinder 62, and a mounting base 63. The upper surface of the abutment plate 61 is fixedly connected to the lifting plate 31. The output end of the lifting cylinder 62 is connected to the lower surface of the abutment plate 61, used to drive the abutment plate 61 to rise and fall vertically, thereby driving the lifting plate 31 to rise and fall synchronously. The mounting base 63 is a U-shaped seat, the bottom of which is fixedly connected to the base plate 22. A mounting hole 64 is provided in the center of the mounting base 63, and the cylinder body of the lifting cylinder 62 passes through the mounting hole 64 and is fixedly connected to the mounting hole 64. Specifically, the lifting cylinder 62 of the lifting drive assembly 60 drives the lifting plate 31 to rise and fall through the abutment plate 61. The U-shaped mounting base 63 provides a stable mounting foundation for the lifting cylinder 62, ensuring sufficient power and controllable stroke for the lifting action, achieving precise lifting of the leather after marking, facilitating subsequent conveying and unloading, and improving the automation and reliability of the lifting process.

[0028] like Figure 4 As shown, the mounting base 63 is connected to guide sleeves 65 on both sides of the lifting cylinder 62, and the guide sleeves 65 are fixedly connected to the mounting base 63. A guide rod 66 is slidably fitted inside the guide sleeve 65, and the upper end of the guide rod 66 passes through the abutment plate 61 and is fixedly connected to the lifting plate 31. Specifically, the guide sleeves 65 and guide rods 66 on both sides of the mounting base 63 slidably fit together to provide precise guidance for the lifting of the abutment plate 61 and the lifting plate 31, avoid lifting deviation, ensure that the lifting plate 31 moves in the vertical direction, improve the straightness and stability of the lifting action, and ensure the posture of the leather after it is lifted.

[0029] like Figure 5 As shown, the conveying unit 40 includes a conveying plate 41, a sliding seat 42, a lead screw 43, and a drive motor 44. The upper end of the conveying plate 41 is fixedly connected to the base plate 22. The upper end of the sliding seat 42 is connected to the conveying plate 41, and the sliding seat 42 is in a transmission cooperation with the lead screw 43. The output shaft of the drive motor 44 is transmissionally connected to one end of the lead screw 43, which drives the lead screw 43 to rotate around its own axis, so as to drive the conveying plate 41 and the base plate 22 to move synchronously through the sliding seat 42. Specifically, the conveying unit 40 adopts a lead screw 43 transmission structure. The drive motor 44 drives the lead screw 43 to rotate, and the sliding seat 42 realizes the precise displacement of the conveying plate 41 and the base plate 22. The transmission accuracy is high and the movement is stable, which meets the conveying and unloading requirements after leather marking and improves the controllability of the conveying action.

[0030] like Figure 5As shown, a fitting groove 45 is provided above the conveyor plate 41, and the base plate 22 is fitted into the fitting groove 45, with the fitting groove 45 and the base plate 22 being adapted and matched. Specifically, the fitting groove 45 of the conveyor plate 41 and the base plate 22 are adapted and fitted together, forming a precise positioning of the base plate 22, making the connection between the base plate 22 and the conveyor plate 41 more stable, preventing the base plate 22 from shifting during the conveying process, ensuring the structural stability when the conveyor unit 40 drives the clamping unit 20 to move, and ensuring the accuracy of the leather conveying path.

[0031] The working principle of this utility model is as follows: During operation, the leather to be marked is first placed on the support plate 21 of the clamping unit 20. Several clamping components 50 clamp and fix the leather evenly from multiple points along the length and width of the support plate 21, followed by laser marking. After marking is completed, the drive motor 44 of the conveying unit 40 drives the lead screw 43 to rotate, which drives the clamping unit 20, which is fixedly connected to the base plate 22, to move along a preset direction through the sliding seat 42, conveying the leather to the unloading station. After reaching the station, the clamping components 50 release the leather, and then the lifting unit 30... The lifting cylinder 62 drives the lifting plate 31 to rise vertically along the clearance hole 24 in the middle of the bearing plate 21 through the abutment plate 61, lifting the leather and completing the unloading through the gripping device. During this process, the support feet 23 at the four corners of the lower surface of the bearing plate 21 provide stable support for the bearing plate 21 and reserve the lifting stroke. The guide sleeves 65 and guide rods 66 on both sides of the mounting base 63 ensure that the lifting plate 31 rises and falls smoothly without deviation. All components work together to realize a fully automated and precise process of clamping, marking, conveying, releasing, lifting and unloading.

[0032] The above description merely illustrates the preferred technical solution of this utility model, and while the description is relatively specific and detailed, it should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
