[0026] Working principle:

[0027] When using this suction cup assembly for the loading and unloading machine, firstly, the fixing frame 1 is installed on the drive end of the loading and unloading machine using screws and other components. Then, the position of the suction cup 4 is adjusted according to the size of the board to be processed. By pulling the connecting plate 10 with the handle, the guide rod 8 and the guide block 9 are driven to compress the fixing spring 11, so that the fixing pin 12 is disengaged from the fixing hole on the fixing frame 1. Then, the connecting rod 2 is moved along the guide groove of the fixing frame 1, and the air pipe 3 moves synchronously along the sliding groove until the suction cup 4 reaches the preset position. The connecting plate 10 is then released, the fixing spring 11 is reset and pushes the guide block 9, so that the guide rod 8 drives the fixing pin 12 to insert into the corresponding fixing hole, thus completing the position fixing of the connecting rod 2 and the suction cup 4.

[0028] When adsorbing the board, the suction pipe 7 on the limiting plate 6 is connected to the external negative pressure device. The negative pressure enters the ventilation groove of the connecting rod 2 through the suction pipe 7, and then is transmitted to the suction cup 4 through the ventilation pipe 3. Under the action of negative pressure, the suction cup 4 is tightly attached to the surface of the board to achieve stable adsorption. The limiting ring 5 on the outer wall of the ventilation pipe 3 limits the connection position between the ventilation pipe 3 and the connecting rod 2, and between the ventilation pipe 3 and the suction cup 4, to prevent loosening due to force during the adsorption process.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
