[0011] The beneficial effects of the present utility model are as follows:

[0017] The present utility model will be further described below in conjunction with the accompanying drawings:

The workpiece transfer handling robot arm 9 takes out the workpieces in the trays and places them on the workpiece transfer positioning seat 62, waiting for the loading and unloading handling robot arm 4 to pick up the workpieces. Among the three groups of feeding mechanisms 52, the tray lifting buffer device 7 is used to buffer the trays waiting for processing. When the conveyor belt device 54 supplies the trays from the previous process, and the workpieces on the trays on the tray positioning seat 61 in the feeding mechanism 52 of this process have not all been processed, the tray clamping device 83 first transports the trays to the tray lifting buffer device 7 for buffering and standby, avoiding setting too long waiting time and improving production efficiency.

The workpiece loading clamping device 42 clamps the processed workpieces from the grinding machines and places them in the trays on the tray positioning seat 61 for unloading.
