This utility model relates to the field of
polishing inspection technology, and provides an online inspection device for the surface
polishing quality of
metal products. It includes a worktable, a
belt conveyor at the top of the worktable, a placement component at the top of the worktable, and a detection component at the center of the top of the worktable. The detection component includes a support, which is fixedly connected to the worktable. In this utility model, when the placement component moves the
metal product into the cleaning box, an
air pump is activated. The
air pump delivers gas into the air supply
pipe, then into the air inlet
pipe, and finally sprays it out through the connecting air frame. The sprayed high-pressure gas blows away the
abrasive particles adhering to the
metal product. Simultaneously, the
air pump delivers air, and the first suction
pipe generates suction, causing the second suction pipe to generate suction. A collection hood absorbs the blown-away
dust particles, thus preventing
contamination of the worktable by the particles. This completes the cleaning process, eliminating the need for manual cleaning and improving work efficiency.
