The cleaning work of the invention is as follows:
after the first air bag 6 and the second air bag 7 polish the adhesive at the connection part of the frame 001 and the battery piece 002, a large amount of adhesive scraps are adhered to the surfaces of the first air bag 6 and the second air bag 7 and the connection part of the through hole 6a and the clamping part 7a, wherein the surfaces of the first air bag 6 and the second air bag 7 and the clamping part 7a can be cleaned well through simple cleaning, but the adhesive scraps in the through hole 6a are difficult to clean in a conventional way;
when the damaged battery piece 002 falls down from between the first air bag 6 and the second air bag 7 in the contracted state, the first air bag 6 is controlled to expand again, so that the through hole 6a is opened, the second air bag 7 can have a moving space, the contracted second air bag 7 is driven to move in the front-back direction by the electromagnet bar 11, the adhered scraps in the through hole 6a are carried out by the second air bag 7 repeatedly moving in the front-back direction, meanwhile, the telescopic part of the third electric push rod 104 is controlled to drive the lower pressure head 105 to move downwards continuously, the external pump is controlled to inject air into the lower pressure head 105, the air is sprayed out from the air holes on the lower pressure head 105 to the first air bag 6, the second air bag 7, the through hole 6a and the clamping part 7a, and the adhered scraps on the surfaces of the first air bag 6 and the second air bag 7 and the connecting positions of the through hole 6a and the clamping part 7a are removed in an air washing mode.
Then, the second air bag 7 is controlled to move backwards to withdraw from the through hole 6a and the perforation 3a, and then the first air bag 6 is controlled to shrink, so that the perforation 3a can be withdrawn smoothly to be subjected to recovery processing of the next batch.
