Application of Automatic Optical Inspection Inspection in Defect Detection of Cover Glass

Application of Automatic Optical Inspection Inspection in Defect Detection of Cover Glass

AOI stands for aoi automated optical inspect equipment. It is a device for detecting common defects encountered in production based on optical principles. It is a relatively standardized branch of visual inspection. The AOI system extracts information from objective images, processes it for understanding, and finally uses it for actual detection, measurement, and recognition. So far, AOI automatic optical inspection has mature applications in PCB, FPD, semiconductor and other industries.

AOI automated optical inspect machine has become an important inspection tool and process quality control tool for electronic manufacturing to ensure product quality, which greatly improves production efficiency and production automation. In the field of PCB manufacturing, electronic components tend to be miniaturized, and the degree of integration is getting higher and higher, and manual detection methods are no longer capable. AOI automatic optical inspection enables PCB manufacturers to greatly improve the yield rate, and has become an indispensable part of the PCB intelligent manufacturing industry.

In the smart phone industry, the "double-sided glass cover + metal middle frame" technology route will further establish itself as the industry's leading position. With the steady growth of global smartphone shipments, the demand for glass covers has been further released. Various cover glass processing manufacturers in the mobile phone industry are actively expanding 2.5D glass production capacity and laying out 3D glass production lines.

Glass processing is a complicated project. Often, there are three quality inspections in the production process of a piece of cover glass. At present, most production lines in the world still use manual inspection. This is not only inefficient, but also cannot guarantee the consistency and accuracy of human eye detection. The introduction of AOI product optical inspection machine is of great significance to improve the yield of cover glass and increase the production line capacity.
Yingshang Intelligent Co., Ltd. has a number of independently developed optical patented technologies, patented mechatronics technologies, image processing and machine learning core technologies. At present, the company has successfully developed a variety of AOI optical automatic detection equipment for glass cover detection systems, which are compatible with the detection of white glass, silk screen glass and OGS glass.
