At this time, since the first sliding block 16 on the bottom surface of the cleaning box 10 is threadedly connected to the outer surface of the threaded column 9, as the threaded column 9 rotates, the first sliding block 16 and the cleaning box 10 assembly slide in the direction of the second guide rail box 7. Further, the vacuum pump 15 and the cleaning motor 11 are controlled to start, and the cleaning motor 11 drives the cleaning roller 12 to rotate, and the detection table 6 is cleaned. The vacuum pump 15 generates suction in the dust box 13 to absorb the swept dust into the dust box 13.
