The specific processing method is as follows:

(1) loading and transporting work

After the counting detection switch 136 detects that the current first groove 1341 in the workpiece placing portion 134 is loaded with a workpiece, the conveyor belt 133 moves the next first groove 1341 of the workpiece placing portion 134 to a workpiece loading position and waits for loading of the workpiece, after the workpiece conveyed from the connecting track 114 is filled in the first groove 1341 on the workpiece placing portion 134, the counting detection switch 136 feeds back a signal to the PLC control system, the PLC control system sends the signal to the fourth motor 134, and the fourth motor 134 drives the driving wheel 131 to drive the conveyor belt 133 to move in the direction of the material taking assembly 210.

The PLC control system is preset with the transport position of the conveyor belt 133. After the picking assembly 210 picks up all the workpieces, the conveyor 133 returns to one end of the stage 120 to load the next batch of workpieces, and the operation is repeated.

(2) Workpiece suction and clamping

After the workpiece placing portion 134 moves to the other end of the object stage 120 along with the conveyor belt 133, a preset position of the workpiece placing portion 134 is preset on the other object stage 120, the third connecting plate 2314 drives the material taking assembly 210 and the pressing assembly 220 to move in the horizontal direction towards the workpiece placing portion 134, and the second air cylinder 2325 drives the pressing assembly 220 and the material taking assembly 210 to move in the vertical direction towards the workpiece placing portion 134.
