Preferably, the clamping assembly comprises a clamping frame 34 and two vacuum chuck assemblies 35, and the clamping frame 34 is provided with a turnover seat and a turnover motor; the overturning motor is used for driving the overturning seat to overturn in a horizontal state and a vertical state; the two vacuum sucker components 35 are respectively and fixedly connected with the end surface and the side surface of the overturning seat. When the operation is got to the realization clamp, because the glass screen of material frame all is vertical state cartridge in the slot of material frame, during the material loading, when carrying out the clamp of glass screen and getting, can make the upset motor drive one of them vacuum chuck subassembly 35 on the upset seat and rotate to vertical state, this vacuum chuck subassembly 35 can directly absorb and be the glass screen that vertical state placed. When the glass screen is processed, the glass screen needs to be horizontally placed on the workpiece carrying platform 12, so that the vacuum west slope component which absorbs the glass screen can be rotated to be in a horizontal state, the glass screen is horizontally placed on the workpiece carrying platform 12, at the moment, the other vacuum sucker component 35 is in a vertical state, the next glass screen can be directly clamped, the process is repeated, and the workpiece taking and placing efficiency is high.

Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
