Description

Technical Field

[0001] The utility model relates to the technical field of automobile manufacturing, in particular to a skid cleaning device. Background Art

[0002] The pre-treatment in the paint shop - the electrophoresis process is the first process for car body corrosion protection. The pre-treatment / electrophoresis liquid contains strong acid, strong alkali, and highly corrosive chemicals, which can effectively clean oil stains, iron filings and other deposits on the car body, and coat the car body layer by layer for corrosion protection.

[0003] Because the pre-treatment-electrophoretic process environment is humid, acidic, alkaline and corrosive, there is often residual electrophoretic paint liquid on the bottom of the skid. The electrophoretic paint liquid is sticky and will accumulate on the running equipment if not cleaned in time, causing equipment failure.

[0004] During the daily production process of the painting workshop, cleaning staff are required to regularly clean the electrophoretic paint liquid remaining on the conveyor roller bed. Manual cleaning on the running equipment is neither safe nor efficient.
