3. starting the separation component 14, the separation baffles 143 on the two sides move close to the trays under the driving of the separation motor 141, and the separation motor 141 is closed until the separation baffles 143 are inserted between the trays to be transported and other trays;

4. the transmission assembly 12 is started again, the material tray to be transmitted is transmitted out, and at the moment, the limit stop 1321 stops other material trays; 5. moving the frame 22 to slide along the slide 211 to the joint with the transmission assembly 12, further starting the driving motor 24 to move the transmission rack 23 along the axial direction of the screw 25, and further enabling a certain layer of tray storage and transmission layer 26 on the transmission rack 23 to be connected with the tray on the transmission assembly 12, at this time, the second displacement sensor signals to control the driving motor 24 to stop;

6. the motors 27 (the motors 27 positioned at the upper and lower sides) corresponding to the layer of the tray storage and transmission layer 26 are started, and the conveyor belt 264 rotates to drive the tray to feed;

7. after the charging tray is fed, the frame 22 is moved again to slide along the slide 211 to the next process, the motor 27 (the motor 27 located in the middle) corresponding to the storage and transmission layer 26 of the charging tray in the layer is started, and the conveyor belt 264 rotates to drive the charging tray to discharge.

Of course, the above steps are only used for explaining the tray conveying system of the embodiment, and do not limit the tray conveying system of the embodiment.

In summary, the present invention provides a tray conveying system, which has the following advantages:

(1) through setting up the subassembly 14 of separating, will wait to transmit the charging tray and separate with other charging trays, realize the branch material transmission of multilayer charging tray, sort efficiently, save the cost of labor.

(2) Furthermore, along the direction perpendicular to the conveying direction of the material tray, at least one pre-positioning assembly 13 is arranged on each of two sides of the material tray so as to abut and position the two sides of the material tray, and the conveying stability and the neatness of the material tray are improved;

(3) the conveying mechanism 2 is in butt joint with the material distributing mechanism 1 to realize continuous conveying of the material trays, meanwhile, the frame 22 can be slidably arranged on the supporting base 21, and the conveying frame 23 can be arranged on the frame 22 in a vertically movable mode, so that the material trays at different transverse positions and height positions can be conveyed, and diversified conveying requirements are met.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. 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.
