An electromagnetic suction cup can also be used. The structure is not limited as long as the function is met.

[0045] Working principle: Loading process: The operator opens the loading door 801 and loads the material into the silo 307. After one silo 307 is loaded, the turntable 308 is controlled to rotate a certain angle to load the next silo until all silos are loaded.

[0046] Unloading process: The transfer and grabbing suction cup 604 on the second transport component 6 grabs the laser-engraved label from the jig 2 and throws it onto unloading chute 1 703 and unloading chute 2 702. The label slides into the receiving bin 701 by its own gravity, thus completing the automatic unloading action. When a certain amount is reached, the worker takes it away for the next process.

[0047] Equipment operation process:

[0048] After the loading action is completed, press the equipment start button and the equipment starts running.

[0049] Action 1: The material lifting linear module 302 in the material storage component 3 moves upward to a certain position, thus completing action 1;

[0050] Action 2: There are two first transport components 4 in the device. At this point, the two transfer components 4 move once in time to grab the materials in the silo 307. When one of the first transport components 4 completes a grab, the slide 302 will move upward to a certain position again, and at the same time, another first transport component 4 grabs the materials therein, and then the first transport component 4 places the grabbed materials on the two fixture components 2 at the rear end. This "fixture position" is also called "laser carving position". Action 2 is completed here.

[0051] Action 3: After completing action 2, the device controller sends a completion signal to the laser engraving component 5, and then the laser engraving component 5 starts to perform laser engraving on the sign. After completing the laser engraving, the laser engraving component 5 sends a laser engraving completion signal to the main control, thus completing action 3;

[0052] Action 4: After receiving the laser engraving completion signal from the main control, the second transport component 6 is activated to grab the laser engraved sign and place it on the two fixture components 2 located in the front, also called the "laser engraving completion waiting position". At the same time, the material on the laser engraving completion waiting position is grabbed and thrown onto the first unloading chute 703 and the second unloading chute 702, thus completing action 4.

[0053] When the equipment is operating normally, the action flow is to continuously cycle action one to action four. If the materials in the six silos 307 are all used up, they can be added manually.
