Carefully place the aluminum-based copper-clad plate to be detected on the detection table 4, and try to make it located in the middle of a clamping device, so as to be clamped by uniform force subsequently. Start the second motor 11 through the control system, so that the bidirectional screw rod 12 starts to rotate. Since the screw threads at the left and right ends of the bidirectional screw rod 12 are opposite in direction, when the screw rod rotates, the sliding blocks 13 on both sides will move towards the center. With the movement of the sliding block 13, the clamping plate 14 fixedly installed on the top wall thereof will also gradually approach the aluminum-based copper-clad plate. When the clamping plate 14 contacts the aluminum-based copper-clad plate, continue to apply appropriate pressure until the pressure sensor 15 senses the preset pressure value, indicating that the aluminum-based copper-clad plate has been firmly clamped.

For the clamping device, it can ensure that the clamping plate 14 contacts the plate with appropriate force, avoiding being too tight or too loose.

[0029] Preferably, in this embodiment, the support frame 2 is designed in an L shape, which allows the support frame 2 to be installed closely to the top wall edge of the workbench 1, without occupying too much working area, and leaving enough operation space for other components. This compact design is very beneficial for optimizing the overall layout and improving space utilization.

[0030] Preferably, in this embodiment, the guide ring 9 and the guide groove 10 are both designed in T shape, the T-shaped guide ring 9 is used in cooperation with the corresponding T-shaped guide groove 10, which can effectively prevent the detection table 4 from moving laterally or tilting during rotation, ensuring that its movement trajectory is accurate and consistent, the T-shaped structure provides additional contact surfaces, increasing the contact area between the guide ring 9 and the guide groove 10, thereby enhancing the overall stability of the system and reducing the possibility of vibration and shaking.

[0032] Preferably, in this embodiment, the moving wheel 18 is a universal wheel, which allows the workbench 1 to move easily in any direction, not limited to straight-line movement forward or backward or left or right, but also includes diagonal or other arbitrary angle direction adjustment, this feature greatly improves the maneuverability and flexibility of the equipment, facilitating quick position adjustment according to actual needs.
