[0004] The traditional clamp adopts vacuum negative pressure adsorption to adsorb the plate from the bottom surface, so that the plate will not move, but this design has some obvious defects, such as the adsorption contact surface is relatively large, the contact part cannot be effectively focused and cut, the remaining surface of the material except the contact surface with the adsorption surface will shake during the platform moving process, the adsorption force is not easy to control and adjust, and the plate and the adsorption surface are pressed to damage the surface of the plate when the adsorption force is too small or too strong, and when the irregular plate is adsorbed, the vacuum adsorption may fail due to the failure of the adsorption area covering.
