[0021] In this embodiment, the processed parts are placed on the placement table 8. By activating the electric telescopic rod 6, when the electric telescopic rod 6 extends or retracts, the adjusting plate 7 slides up and down along the support rod 4. The adjusting plate 7 drives the connecting plate 12 to move. The connecting plate 12 is connected to the connecting frame 10, which enables the connecting frame 10 to drive the clamping arm 11 to move, thereby clamping the parts and achieving precise operation of clamping the parts. The spring 19 sleeved on the outside of the support rod 4 plays a buffering role during the movement of the electric telescopic rod 6, ensuring the smoothness of the up and down movement.

[0022] Furthermore, a rotary motor 20 is fixedly connected to one side of the lower surface of the worktable 1, and the bottom end of the rotating cylinder 2 is fixedly connected to the output end of the rotary motor 20; a TOF camera 13 is fixedly connected to one side of the outer wall of the worktable 1, and a weight sensor 14 is fixedly connected to the upper surface of the placement platform 8.

[0023] The TOF camera 13 is used to detect the position and transfer path of the parts in the processing environment and acquire the point cloud data of the parts. At the same time, the rotary motor 20 is started to drive the rotating drum 2 to rotate, so that the parts can be rotated and the TOF camera 13 can scan the parts from all directions. The robotic arm 23 can pick up the parts and transfer them to the next step. The weight sensor 14 is installed on the placement table 8, which can accurately detect the weight of the parts and can be used to confirm whether the parts have been correctly placed or picked up.

[0024] Furthermore, a fixed frame 21 is fixedly connected to the other side of the outer wall of the workbench 1, a bracket 22 is fixedly connected to the lower surface of the fixed frame 21, a robotic arm 23 is installed at the bottom of the bracket 22, and a force sensor is installed at the end of the robotic arm 23.

[0025] The robotic arm 23 is equipped with a force sensor at its end to sense the force during the gripping process in real time, ensuring the stability of the gripping and preventing excessive force from damaging the parts.

[0026] Furthermore, a conveying assembly 15 is installed on the other side of the upper surface of the workbench 1;

[0027] The conveying component 15 can be used to assist in the transfer of parts and improve processing efficiency.

[0028] Preferably, the outer wall of the connecting plate 5 is provided with a groove 16, the inner wall of the groove 16 is fixedly connected to a fixing rod 17, one side of the connecting plate 12 is rotatably connected to the outer wall of the fixing rod 17, one of the connecting brackets 10 is fixedly connected to the upper inner side of a connecting rod 18, and the other side of the connecting plate 12 is rotatably connected to the outer wall of the connecting rod 18.

[0029] The working principle and usage process of this utility model are as follows: The machined part is placed on the placement table 8. The electric telescopic rod 6 is activated. When the electric telescopic rod 6 extends or retracts, the adjusting disc 7 slides up and down along the support rod 4. The adjusting disc 7 drives the connecting plate 12 to move. The connecting plate 12 is connected to the connecting frame 10, thereby enabling the connecting frame 10 to drive the clamping arm 11 to move, thus clamping the part and achieving precise clamping. The spring 19 sleeved on the outside of the support rod 4 acts as a buffer during the movement of the electric telescopic rod 6, ensuring the smoothness of the up and down movement. A TOF camera 13 is used to detect the zero-element components in the machining environment. The system detects the location and transfer path of the component, acquires point cloud data of the component, and simultaneously starts the rotary motor 20 to drive the rotating drum 2 to rotate, thereby enabling the component to rotate and allowing the TOF camera 13 to perform omnidirectional scanning of the component. The robotic arm 23 is set up to pick up the component and transfer it to the conveying assembly 15. The placement table 8 is equipped with a weight sensor 14, which can accurately detect the weight of the component and confirm whether the component has been correctly placed or picked up. The robotic arm 23 is equipped with a force sensor at its end to sense the force during the clamping process in real time, ensuring the stability of the clamping and preventing excessive force from damaging the component.
