This invention relates to the field of galvanized parts inspection technology, and in particular to a device for detecting the
coating thickness of galvanized parts. The device includes a
conveyor belt, a
laser thickness gauge for detecting the
coating thickness of galvanized parts mounted above the
conveyor belt, two support frames fixed to the top of the
conveyor belt to support the
laser thickness gauge, and a reader for reading the data from the
laser thickness gauge mounted above the support frames. A spacing adjustment mechanism for adjusting the position of the laser thickness gauge is provided between the support frames and the laser thickness gauge. A central sampling mechanism for sampling and photographing the
coating surface of the galvanized parts is also provided on the side of the support frames. This invention, through the cooperation of the conveyor belt, support frames, laser thickness gauge, reader, spacing adjustment mechanism, adjustment frame, transmission rod, transmission wheel, and fixing plate, can accurately target the corners, edges, and other protruding and easily worn areas of the galvanized parts, achieving full-area coating quality detection and meeting comprehensive and accurate inspection requirements.
