[0110] Movement process of pallet loading and unloading components:

[0111] The tray loading and unloading assembly is installed at the output port of the equipment by screws, and this part is directly connected to the rear PVD coating machine. The initial state of the tray assembly loading split belt part C and the split screw part D is open. The initial state of the cover transfer part F is that the entire transfer gripper is located in the middle position of the split belt, and the cylinder in the cover transfer part F is in a retracted state.

[0112] The working principle is that the PVD coating machine outputs the tray assembly (the tray below, with a cover plate on the tray), directly outputs it to the roller of the tray assembly unloading and conveying roller part B in the tray loading and unloading assembly, and then continues to convey it forward to the rib 212 of the tray assembly unloading and conveying roller part B. At this time, the photoelectric signal of the tray assembly loading part E is given, and the module in the tray assembly loading part E drives the tray assembly to rise to a position higher than the conveyor belt position in the tray assembly loading split belt part C. At this time, the split screw part D drives the screw and then drives the tray assembly loading split belt part C to a retracted state, and then the tray assembly loading part E moves down to place the tray assembly on the conveyor belt of the tray assembly loading split belt part C. At this time, the conveyor belt conveys the tray assembly forward and conveys it to the buffer pad mounting plate 316. After it is in place, the photoelectric signal is transmitted to the cover plate transfer part F to extend its cylinder, and the suction cup absorbs the cover plate. Then the cylinder in the cover plate transfer part F retracts, and the cover plate is completely moved out from above the tray under the action of the transfer module 602. So that the mobile phone glass can be grabbed and placed on the tray, when the tray is full of mobile phone glass, the cover plate needs to be moved back to cover the tray full of glass, and then the tray assembly loading split belt part C reverses and outputs the entire tray assembly full of glass to the PVD coating machine. In this way, the loading and unloading of a tray assembly is completed.

[0113] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements of the present invention by relevant technical personnel in the field should be extended to the protection scope determined by the claims of the present invention.
