Full-automatic visual inspection system for screen defects

Abstract

The invention relates to a full-automatic visual inspection system for screen defects. The system comprises a controller as well as an automatic feeding unit, an automatic inspection unit and an automatic classifying and discharging unit which are connected with the controller; the automatic feeding unit, the automatic inspection unit and the automatic classifying and discharging unit are sequentially arranged to form an automatic assembly line; the automatic feeding unit conveys to-be-inspected screens to the automatic inspection unit; the automatic inspection unit performs automatic defect inspection to determine whether the screens belong to non-defective products or defective products; and the automatic classifying and discharging unit acquires the inspected screens from the automatic inspection unit and performs classification and output according to inspection results. Compared with the prior art, the system has the advantages that the automation degree is high, the whole inspection process is simple to operate, the labor intensity of workers is reduced, the human capital is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a screen defect detection system, in particular to a screen defect automatic visual detection system. Background technique [0002] With the rapid development of science and technology, LCD electronic products, especially smart phones, have become an indispensable part of people's daily life. There are also higher requirements for the quality of the screen. In the production process of thin-plate electronic products such as LCD screens and mobile phone touch screen glass, due to objective factors such as production technology, it is impossible to completely avoid various defects (such as screen scratches, glass screen stains, glass screen size mismatch, etc.) edge chipping, sawtooth, missing corners, etc.). Therefore, the appearance inspection of the screen is required before each process. [0003] The appearance defect detection of traditional LCD screens and mobile phone glass products mainly relies on manual inspection wi...

AI Technical Summary

Problems solved by technology

[0003] The appearance defect detection of traditional LCD screens and mobile phone glass products mainly relies on manual inspection with special light sources or projectors. Due to the many influencing factors of manual inspection, not only the accuracy of inspection and the uniformity of standards cannot be guaranteed, but also cannot meet the requirements. The needs of modern enterprises for batch and rapid production

[0004] Existing automatic detection devices can only detect screens of a certain size, and generally can only detect large defects, and cannot measure the actual size of defects, and cannot set detection standards for actual production needs. The degree of automation is not high. high

Such as patent (publication number CN205643188U, publication number CN205301189U) has no automatic loading and unloading mechanism, and the efficiency is not high
