Specifically, when the number of stacked layers of long hardware sheets on the pallet 16 is small, in order to facilitate the first robot 2 to pick up the material, the first motor 12 can drive the first screw rod 13 to rotate, so as to drive the pallet 16 connected to the first threaded seat 14 to move upward, thereby increasing the height of the pallet 16.
