[0075] Step 1: The manipulator drives the carton stacking fixture to move above the grouped carton layer, and the clamping drive mechanism 23 drives the two groups of insertion and extraction racks 21 to move in a direction away from the length center line of the frame 1, so that the closest distance between the two groups of fork rods 22 is greater than the length of the carton layer, and the manipulator drives the carton stacking fixture to descend, so that the fork rods 22 are located below the bottom surface of the carton layer;

At this time, the suction part of the suction cup 51 is in contact with the separator paper, and the vacuum generator 52 provides negative pressure for the suction part to absorb the separator paper;

[0079] Step 5: After sucking up the separator paper, the robot drives the carton stacking fixture to the pallet position to complete the separator paper placement action (the process is the opposite of the separator paper removal action).
