The utility model provides a
glass window cleaning device applied to the surface of cold-rolled
strip steel. Comprising the following steps: a first
glass window and a second
glass window are respectively arranged above and below a position area through which cold-rolled
strip steel passes in a meter detection box body; the first guide rod is arranged on the lower side of the first glass window and extends in the length direction of the meter detection box body, the first cleaning
brush is installed on the first guide rod through a sliding block, the first cleaning air cylinder is fixed to the inner wall of the meter detection box body, and a first
piston rod at the output end of the first cleaning air cylinder is connected with the first cleaning
brush; the second guide rod is arranged on the upper side of the second glass window and extends in the length direction of the meter detection box body, the second cleaning
brush is installed on the second guide rod through a sliding block, the second cleaning air cylinder is fixed to the inner wall of the meter detection box body, and a second
piston rod at the output end of the second cleaning air cylinder is connected with the second cleaning brush. Therefore, a traditional mode depending on manual wiping is effectively replaced, the optical permeability of an imaging area is effectively guaranteed, and the image definition in the cold-rolled
strip steel surface defect detection process is improved.
