Then, the PCB board clamping device 26 drives the PCB board to move to the middle of the frame 27 for printing. After printing, the sorting device 32 adjusts the PCB board again, and a printing operation can be completed.

[0039] Compared with the prior art, the beneficial effects of the present invention are:
