Abstract

The invention provides an interactive semi-automatic grating surface defect detection device and a method using the device, and relates to a defect detection device and the method using the device. The problems that an existing grating surface defect detection device is low in detection precision, low in detection efficiency, poor in anti-interference performance and high in cost are solved. According to the detection device, a motion control cabinet, a grating surface unfolding unit and a first image collecting system unit are sequentially arranged on a detection worktable from left to right in parallel, and a second image collecting system unit and the first image collecting system unit are connected. The defect detection method has the advantages of being high in automation degree, high in detection precision and detection efficiency, high in objectivity and not prone to causing eyestrain. Alignment of the position of a grating to be detected is achieved by driving an electric two-dimensional translation table, and the alignment mode has the advantages of being high in objectivity, high in positioning precision and good in stability compared with manual alignment. The device and the method are used for interactive semi-automatic grating surface defect detection.

Description

Technical field [0001] The invention relates to a grating surface defect detection device and a method of using the device, in particular to an interactive semi-automatic grating surface defect detection device and a method of using the device. Background technique [0002] Defect detection usually refers to the detection of surface defects of objects. Surface defect detection uses advanced machine vision detection technology to detect spots, pits, scratches, color differences, defects and other defects on the surface of the workpiece. Existing manufacturers generally use manual inspection methods for grating surface defects, which have the following characteristics: the alignment of the position to be inspected on the grating needs to be realized manually, which has the characteristics of strong robustness, poor positioning accuracy and high repeatability. Incandescent lamps are commonly used as transmission light sources, which have the characteristics of low brightness and lig...
