Problems solved by technology
[0005] Taking mobile phone casings as an example, due to reasons in the manufacturing process, some products may have quality defects such as dents, scratches, bumps, and burrs on the appearance.
At present, most parts manufacturers rely on manual inspection of the appearance quality of mobile phone casings, which is prone to false detection and missed detection, which brings a lot of economic losses to the manufacturers. Therefore, efficient and accurate intelligent automatic detection devices are urgently needed
Existing intelligent devices (such as invention patent CN102218406A) that use image processing technology to detect mobile phone shells require complex pattern recognition algorithms, and some also need to install detection lenses at multiple angle positions (such as utility model CN203455286U). The method is not easy to implement, and the accuracy and precision of detection are not ideal enough

Embodiment Construction
[0035] The present invention will be described in further detail below in conjunction with specific embodiments.
[0036] Such as figure 1 The detection device used to detect the edge of the mobile phone shell is used to intelligently detect the appearance quality of the edge of the mobile phone shell, including a control unit, a data acquisition module, a two-dimensional laser scanning sensor, an electrical drive module, and a fixture for the mobile phone shell. Shell installation platform 7 , clamp manipulation mechanism 5 , clamp locking mechanism 6 and base 2 .
[0037] The two-dimensional laser scanning sensor is installed on the base 2, and its output end is connected with the input end of the data acquisition module, which is used to scan the contour data of the edge of the mobile phone case and transmit it to the data acquisition module. The installation method is that the two-dimensional laser scanning sensor is installed at a position equal to the horizontal centerl...
