[0104] During specific operation, the loading roller 8 is docked with the AGV trolley (existing technology) for feeding / retrieving materials. When the pallet 10 is loaded in place, it will be attached to the dead stop. At this time, the proximity switch sends a command and the loading roller 8 stops rotating. The centering cylinder of the loading roller 8 is pushed out to fix the pallet 10 on the loading roller 8. At this time, the X / Y / Z three-axis of the walking mechanism drives the pallet cleaning clamp 6 to reach down and grab the pallet 10. First, the cylinder 605 extends the full stroke, and then under the guidance of the guide pressure block 602, the clamp hook 604 reaches down to the grabbing position. At this time, the cylinder 605 is retracted, and the clamp hook 604 is retracted with the cylinder 605, and is lifted up with the pin hinge point as the center of the circle, until the clamp hook 604 clamps the inner wall of the guide groove of the pallet 10 itself, and the pallet 10 is separated from the feeding roller. After the two proximity switches sense the pallet 10 at the same time, feedback signals are fed back, and the pallet cleaning clamp of the walking mechanism then moves the pallet 10 to the cleaning position. The servo motor 608 is started at this time, which will drive the whole and then drive the pallet 10 to flip to 90°, and finally send it to the inside of the cleaning tank for cleaning. The centering cylinder of the feeding roller 8 is retracted, and the pallet 10 is lifted and moved to the upper part of the closed cleaning box 5. Before cleaning, the movable cover 508 of the closed cleaning box 5 is always in an open state. At this time, the pallet cleaning clamp 6 is driven by the servo motor 608 to rotate 90 degrees, and the Z-axis assembly 3 continues to place the pallet 10 downward on the pallet bracket of the movable cover 508. After the movable cover 508 is moved to close, the closed cleaning box 5 is cleaned and dried. The pallet cleaning gripper 6 grabs the pallet 10 and places it on the pallet bracket inside the movable cover 508. The proximity switch detects the presence of material, and the rodless cylinder 502 pushes the movable cover 508 and the pallet 10 toward the spray box. When the movable cover 508 is completely fitted with the spray box, the in-place switch on the spray box sends a command to completely close the box cover, and the nozzle on the water spray pipe 505 in the spray box starts to work, and the pallet is cleaned with high-pressure water. The waste water generated by the cleaning flows into the water receiving trough 504 along the water guide baffle, and the waste water flows into the sewage treatment tank through the drain port of the water receiving trough 504 and the drain pipe. After the pallet 10 is cleaned, the blowing nozzle on the blowing pipe 506 starts to work, blowing compressed air to the cleaned pallet 10 to blow away the residual water on the surface of the pallet 10, and the cleaning of the pallet 10 is completed. After the cleaning and drying is completed, the movable cover 508 is opened, and the above actions are reversed to send the pallet to the unloading roller 7. The AGV car receives and transports the pallet 10 from the unloading roller 7, so that the cleaning of the entire pallet 10 is fully automated. During the interval of cleaning waiting, the pallet 10 can be continuously grabbed and placed in the buffer rack 9. There are three buffer racks 9 for each dirty pallet 10 and clean pallet 10 to improve the cleaning cycle.

Therefore, these modifications or improvements made without departing from the spirit of the present utility model all fall within the scope of protection required by the present utility model.
