At this time, after the mechanism for clamping or hooking materials connects and fixes the material, the slide drive device 42 rotates in the opposite direction to move the material to the side of the docking component 3. When the material contacts the docking component 3, the roller drive device 33 drives the rotating roller 322 to rotate, and transfers the material to the middle of the fixed frame to complete the material picking.
