| Summary: | 碩士 === 國立雲林科技大學 === 電機工程系 === 106 === This article uses Automated Optical Inspection, AOI technology to detect flaws on metal surfaces. This article uses linear slides as the test object to reduce manpower, increase productivity, and increase product quality. At present, linear slides have a tendency to strengthen in Taiwan's machinery exports. With the popularization of Industry 4.0 automation, the demand for automated mechanical components has also increased. If the slide rails of the linear slide rails are uneven, vibration will occur, which will cause the coordinates or positioning of the automation mechanism to be inaccurate and have a great influence. Because the resulting protruding part will be smoothed at the end, but the flattening can not solve the problem of the sag of the depression, this paper will use the LED triangulation method in 3D mechanical vision to find the area of the linear sliding surface with a depression of 0.1mm. Areas with inconsistent specifications are marked to assist the manufacturer to establish a defect detection station on the production line, which will successfully detect the concave portion of the surface of the linear slide.
