S3: when the infrared image scanner (410) detects that cracks appear on the mask, the cracks are transmitted to the computer terminal through the lead, so that workers are reminded of mask faults, and the cracks are not transmitted to the computer terminal when the cracks are not detected;
s4: after the detection is completed, the mask is pushed to move, and finally the mask is pushed onto the second conveying belt (216).
