When the grabbing mechanism 6 grabs and transports the plate 28 on the conveyor belt 5 to the position above the material tray 4, the grabbing mechanism 6 drives the plate 28 to integrally descend. When the material tray 4 does not have the plate 28, the grabbing mechanism 6 drives the first plate 28 to move to a height of 3cm-10cm (8 cm in the embodiment) of the inner bottom surface of the material tray 4, and the grabbing mechanism 6 loosens the plate 28 to enable the plate 28 to fall freely to the bottom of the material tray 4. If the plate 28 is arranged in the material tray 4, the plate 28 on the grabbing mechanism 6 is loosened by the grabbing mechanism 6 when the distance from the plate 28 at the top end in the material tray 4 is 8 cm. The distance control can be, but not limited to, automatic control by a photoelectric sensor or manual control, and the two control modes are mature prior art and are not described herein.
