Description

technical field [0001] The invention belongs to the field of mobile phone panel and backplane quality detection, and in particular relates to a multifunctional mobile phone backplane automatic measurement device and measurement method capable of automatically completing the size measurement, flatness measurement, transmittance measurement and surface stress measurement of the mobile phone backplane. Background technique [0002] With the rapid development of modern technology, especially the rapid development of electronic products such as smart phones and tablet computers, as an important part of electronic products, mobile phone backplanes have received more and more attention. Especially with the practical application of the 3D backplane structure of the mobile phone, the performance requirements for the backplane of the mobile phone are gradually increasing. Among the many parameters of the mobile phone backplane, the size, flatness, transmittance, surface stress and oth...

Problems solved by technology

[0003] At present, the main tools for testing the quality of mobile phone backplanes on the market are: image measuring instruments, microscopes, calipers, three-coordinate measuring machines, profilers, spectral transmittance measuring instruments, and surface stress instruments. Although these testing tools are various , but using image measuring instruments, tool microscopes, calipers and other measuring tools can only measure the length, width, round holes, waist-shaped holes, rounded corners, and the outline size of the silk screen pattern on the back of the mobile phone; using a three-dimensional coordinate measuring machine can only measure the length , width, round hole, waist-shaped hole, rounded corner, silk screen pattern outline size, thickness, height, surface flatness or contour; using a profiler can only measure flatness and contour; using a spectral transmittance measuring instrument can only measure It can measure the relative light transmittance of the mobile phone backplane; the surface stress meter can only measure the stress on the surface of the mobile phone backplane, so the existing detection methods need to be divided into size measurement, flatness measurement, transmittance measurement, surface stress measurement, etc. Measurement process, each measurement process only tests one of the parameters of the mobile phone backplane. After one process is completed, the sample to be tested is placed manually in the next process. The samples to be tested are placed in different storage places

The existing detection method requires multiple detection equipment, which occupies a large space and has high requirements for the detection environment. The detection process is intermittent and discontinuous. The measurement process takes a long time and the measurement efficiency is low. It cannot meet the needs of mass detection. Manpower, time-consuming and labor-intensive, manual sorting after the inspection is easy to cause sorting errors, resulting in the misplacement of unqualified products, thus affecting the subsequent use performance of mobile phone backplane products
