[0002] The traditional production and operation model relies more on labor costs and scale advantages, but with the continuous increase in labor costs in recent years, it will face the competitive pressure brought by changes in the external environment and the operating pressure brought by changes in the industry environment. In addition, the process change cycle of consumer electronic products such as smart phones is getting shorter and shorter, and the product precision is getting higher and higher. The structural parts of mobile phones have shown the characteristics of material diversification and mass production of models. Some tooling and fixtures only play the role of fixing workpieces, mainly through manual inspection, and cannot detect multiple workpieces at the same time, which does not meet the process requirements. At present, the height detection of shrapnel mainly uses laser scanning detection. When using line laser detection, the detection time is long, the efficiency is low, and the cost is high; when using point laser detection, only shrapnel with a flat top and a large area can be detected. The error of the shrapnel with a circular arc surface at the top is large, which is difficult to meet the process requirements. With technological innovation and changes in market demand, automated factories are also the trend of industrial development in today's era, so it is urgent to develop new processes and new equipment to meet the needs of production processes, so as to improve cost competitiveness, output, and reduce labor costs.
