  • a first frame structure;

    a second frame structure with a material area for holding stacked material trays;

    a clamping mechanism, comprising a driving motor mounted on the first frame structure, two rotating shafts driven by the driving motor, and a clamping assembly arranged on the rotating shafts, a separation area being formed between the two rotating shafts and located above the material area, the clamping assembly comprising two main clamping portions located on left and right sides of the separation area, each of the main clamping portions comprising a main cam mounted on the respective rotating shaft and a main clamping block following the main cam, the two main cams respectively driving the two main clamping blocks to extend into and withdraw from the separation area, the rotating shafts rotating between an initial station and a clamping station, and the main cams being configured that when the rotating shafts rotate to the initial station, the main cams drive the main clamping blocks to withdraw to release the material tray, and when the rotating shafts rotate to the clamping station, the main cams drive the main clamping blocks to extend to clamp the material tray;

    a lifting assembly controlling relative movement of the clamping mechanism and the second frame structure; and

    each of the main clamping portions further comprising a guiding element fixed to the first frame structure, and each of the main clamping blocks being movably engaged with the guiding element and moved under the limitation of the guiding element.
