[0032] Among them, the cantilever 6 plays a role of carrying materials, and the guide assembly 9 is used to reduce the friction between the materials and the cantilever 6 during movement.

[0033] When collecting materials, the cantilever 6 is docked with the docking guide shaft sleeve of the buffer rack or the machine table, the gripper 2 is driven by the first driving mechanism 5 to move towards the front end of the cantilever 6, so that the gripper 2 collides with the materials, the clamping jaw assembly 10 is further closed to hold the materials, and the first driving mechanism 5 is further driven to move the gripper 2 towards the rear end of the cantilever 6 to reset, so as to realize the material collecting operation, at this time, the gripper state is as shown in Figure 2 .
