In the second tray conveyor 200, since the material transfer unit needs to move the material from the tray loaded on the second tray conveyor 200, a stack of trays transported by the first tray conveyor 100 is sequentially placed to the second tray conveyor 200 by the first suction mechanism 300, in order to ensure that the material transfer unit can accurately move the material from the tray loaded on the second tray conveyor 200, the positioning mechanism 130 of the second tray conveyor 200 in this embodiment needs to position a tray each time the first suction mechanism 300 moves a tray, if the first suction mechanism 300 directly places a tray on the second support plate 122 of the second tray conveyor 200, as the number of trays loaded on the second support plate 122 of the second tray conveyor 200 increases, the positioning mechanism 130 gradually increases the difficulty of positioning the tray loaded on the second support plate 122 of the second tray conveyor 200, and the positioning accuracy gradually decreases, in order that the positioning mechanism 130 moves the tray 200 to the second suction mechanism 142 in the direction of the second tray conveyor 142, and then the second suction mechanism moves the tray conveyor 200 to the second tray conveyor 142, and when the second suction mechanism moves the tray conveyor 200 to the tray 142, the tray conveyor 142, and the second tray conveyor 200 is in the direction, and the second tray conveyor 142 is moved to the second tray conveyor 142, and the second suction mechanism 142, and then the material transfer device moves the tray conveyor 200 to the second tray conveyor device is in the second tray conveying direction of the second tray 142, thereafter, the flat plate 142 is reset, and the second support plate 122 of the second tray conveyor 200 is lowered in the vertical direction so that the flat plate 142 can carry the next tray carried by the first suction mechanism 300. Based on the above, the second pallet conveying device 200 in the embodiment can ensure that the material transfer unit can accurately carry the material by the second driving member 141 and the flat plate 142.

Accordingly, like the second tray conveyor 200, the fourth tray conveyor 700 and the fifth tray conveyor 800 can ensure that the material transfer unit can accurately sort the materials into the trays by the second driving member 141 and the flat plate 142.

It is understood that the second driving member 141 in the present embodiment can be selected from a linear driving structure such as an air cylinder, an electric cylinder, or an electric push rod, which is not particularly limited in the present embodiment.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Numerous obvious variations, rearrangements and substitutions will now occur to those skilled in the art without departing from the scope of the invention. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
