This position is the placement position.

[0055] Step 7: Control the operation of the cylinder of the slide cylinder module 3 so that the slide of the slide cylinder module 3 drives the suction cup assembly 2 to move downward to the designated position; at this time, through pneumatic control, the air source does not provide vacuum suction force to the receiving suction cup 24, and the sheet falls off the receiving suction cup 24 and lands on the corresponding sheet collection station.
