[0002] The loading and unloading mechanism is an automatic or semi-automatic mechanical device that delivers the workpiece to be processed to the processing position on the machine tool and removes the processed workpiece from the processing position. It is also called a workpiece automatic loading and unloading device. A robot is a machine device that performs work automatically. It can accept human commands, run pre-programmed programs, or act according to the principles formulated by artificial intelligence technology. Its task is to assist or replace human work, such as manufacturing, construction, or dangerous work.

[0003] For example, Chinese patent publication number CN215880923U discloses a six-axis robot loading and unloading mechanism, which includes a workbench, a six-axis robot assembly and a material tray assembly. The six-axis robot assembly includes a six-axis robot body, a rotating drive component, a first clamping component and a second clamping component. The material tray assembly includes a sampling tray component and multiple material tray components. The material rods in the processing placement area are sampled, and the material rods that fail the sampling inspection are placed on the sampling tray component.

At the same time, through the connecting plate 35 at the bottom, the mechanical arm 4 can follow the movement, so that the mechanical arm can reach various positions in the working area and perform different tasks.

[0031] The fixing mechanism 52 includes a mounting block 521, on which a pneumatic gripper 522 is mounted, and a clamping block 524 is respectively disposed on two output ends 523 of the pneumatic gripper 522.
