[0037] To use the device, first place the base 1 on a workbench, install the suction cup assembly 5, connect the vacuum cup 501 to the suction cup mounting plate 503 via the air line fixing tube 502, and then connect the air line fixing tube 502 to the vacuum generator 6 via the air line hose, ensuring that the air line is properly sealed and leak-free.

[0038] When clamping the workpiece, start the vacuum generator 6 to draw air from the vacuum suction cup 501 to generate vacuum suction; according to the size of the drone shell, the second screw 301 is driven to rotate by the motor 2, so that the vertical adjustment mechanism 4 on the horizontal adjustment mechanism 3 moves relative to or away from each other along the second guide rod 302 to a suitable horizontal position, thereby adjusting the horizontal distance between the two groups of suction cup adsorption components 5 to adapt to the width of the drone shell; then the first screw 401 is driven to rotate by the motor 1, so that the suction cup adjustment rod 504 moves relative to or away from each other along the first guide rod 402, and the longitudinal distance between the suction cup adsorption components 5 is adjusted, so that the vacuum suction cup 501 can accurately fit the surface of the drone shell to be welded.
