As a complex system, the robotic arm exhibits uncertainties such as parameter perturbations, external interference, and unmodeled dynamics. Therefore, the modeling of the robotic arm also contains uncertainties. For different tasks, it is necessary to plan the motion trajectories of the robotic arm's joints in space, thereby cascading them to form the end effector pose.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the various embodiments of this utility model will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of this utility model to enable the reader to better understand this application. However, the technical solutions claimed in this application can be implemented even without these technical details and with various changes and modifications based on the following embodiments.

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] See Figure 1-4In this embodiment of the utility model, a gripper for robotic arm processing includes a mounting plate 1. A mounting box 3 is fixedly mounted on the mounting plate 1, and a rotating rod 4 is rotatably mounted on the mounting box 3. The rotating rod 4 is connected to the inner wall of the mounting box 3 through a bearing seat. A rotation drive assembly for driving the rotating rod 4 to rotate is installed inside the mounting box 3. A mounting frame 8 is fixedly mounted at the end of the rotating rod 4 located outside the mounting box 3. A clamping frame 9 is fixedly mounted on the mounting frame 8. Connecting sleeves 10 are embedded at both ends of the clamping frame 9. A moving rod 11 is slidably mounted inside the connecting sleeves 10. A connecting bent plate 12 is fixedly mounted at the end of the moving rod 11 located outside the clamping frame 9. Fixed plates 13 are provided at both ends of the outer wall of the clamping frame 9. The fixed plates 13 and the connecting bent plates 12 are connected. 2. Sliding connection: A moving drive assembly for driving the connecting bent plate 12 to move is installed between the fixed plates 13; a connecting frame 17 is fixedly installed at the end of the moving rod 11 located inside the clamping frame 9; connecting recesses 18 are opened on the side walls at both ends of the connecting frame 17; a third motor 19 is fixedly connected to the outer wall of the connecting recesses 18; a rotating shaft 20 is installed on the motor shaft of the third motor 19; the end of the rotating shaft 20 is connected to the connecting recesses 18 through a bearing seat; an auxiliary clamping plate 21 is installed on the rotating shaft 20; sliding members 22 are provided at both ends of the connecting frame 17 located inside the connecting recesses 18; a clamping seat 24 is provided at the inner end of the sliding member 22; a clamping spring 23 is provided on the sliding member 22 located between the clamping seat 24 and the connecting frame 17.

[0021] This invention places the robotic arm between the clamping seats 24, and drives the connecting bent plate 12 to move via the moving drive assembly. The connecting bent plate 12 drives the connecting frame 17 to move inward via the moving rod 11. The clamping seats 24 clamp both ends of the robotic arm. The elastic force generated by the compression of the clamping spring 23 can achieve a tight clamping of the robotic arm. In conjunction with the third motor 19 driving the rotating shaft 20 to rotate, the rotating shaft 20 drives the auxiliary clamping plate 21 to achieve auxiliary clamping of the robotic arm. In conjunction with the rotation drive assembly driving the rotating rod 4 to rotate, the rotating rod 4 drives the mounting frame 8 to drive the clamping frame 9 to rotate and adjust its orientation, thereby achieving orientation adjustment of the robotic arm, which facilitates the processing of the robotic arm.

[0022] See Figure 1 In one embodiment of this utility model, mounting holes 2 are provided at the four corners of the mounting plate 1. The mounting holes 2 facilitate the quick installation of the clamp.

[0023] See Figure 3 In one embodiment of the present invention, the driving component includes a first motor 5 fixedly connected to the inner wall of the mounting box 3. The output shaft of the first motor 5 is provided with a drive gear 6, and a driven gear 7 is meshed on the drive gear 6. The driven gear 7 can drive the rotating rod 4 to adjust its rotational orientation.

[0024] See Figure 4 In one embodiment of the present invention, the moving drive assembly includes a second motor 15 fixedly connected to the outer wall of the fixed plate 13. A bidirectional screw 16 is provided on the motor shaft of the second motor 15. The bidirectional screw 16 is threadedly connected to the connecting bent plate 12. When the second motor 15 works, the second motor 15 drives the bidirectional screw 16 to rotate, and the bidirectional screw 16 can drive the connecting bent plate 12 to move.

[0025] See Figure 4 In one embodiment of this utility model, a guide rod 14 is also fixedly installed between the fixed plates 13. The guide rod 14 is slidably connected to the connecting bent plate 12. During the movement of the connecting bent plate 12, the guide rod 14 guides the connecting bent plate 12, thereby ensuring the smooth movement of the connecting bent plate 12.

[0026] Working Principle: This utility model allows the mounting plate 1 to be fixedly connected to the processing equipment via the mounting hole 2. The first motor 5 drives the drive gear 6 to rotate, which in turn drives the meshing driven gear 7 to rotate. The driven gear 7 can adjust the rotation position of the rotating rod 4, which in turn drives the mounting frame 8 to rotate. The mounting frame 8 can adjust the rotation position of the clamping frame 9. The second motor 15 drives the bidirectional screw 16 to rotate, which in turn drives the threaded connecting bent plate 12 to move. The connecting bent plate 12 moves synchronously with the moving rod 11, which in turn drives the connecting frame 17 to move. The connecting frame 17 moves synchronously with the sliding member 22, which drives the clamping seat 24 to move inward and contact the two ends of the robotic arm. The elastic force generated by the compression of the clamping spring 23 can clamp the robotic arm. In conjunction with the third motor 19, the third motor 19 drives the rotating shaft 20 to rotate, which in turn drives the auxiliary clamping plate 21 to perform auxiliary clamping of the clamped robotic arm. This ensures stable clamping of the robotic arm.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
