Abstract

The invention relates to the field of image processing, in particular to a production quality detection method for a Mini LED thin plate full-automatic connection line, which comprises the following steps of: acquiring an unwelded gray scale image, a welding line gray scale image and a welding spot gray scale image in real time; the method comprises the following steps: acquiring the matching degree of each circle and a standard circle in an unwelded grayscale image; according to the circle center and the radius of each circle and the welding rule, a corresponding welding area is determined; determining a bonding wire in the corresponding welding area image in the bonding wire gray level image, and calculating a bonding wire quality evaluation index; meanwhile, calculating a similarity index of each welding spot image and a standard welding spot template image and obtaining a change degree of the lamp bead; and performing weighted summation on the matching degree, the bonding wire quality evaluation index, the similarity index and the change degree to obtain a comprehensive production quality index, and judging whether the MiniLED thin plate is qualified or not. According to the scheme, the quality of the technological process of the whole production line can be monitored, and therefore quality detection of the MiniLED thin plate is achieved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a production quality detection method for fully automatic connection of MiniLED thin plates. Background technique [0002] At present, Mini LED has become one of the important technology trends in the display industry. As a display technology transitioning from LED to Micro LED, it has the advantages of thinning, miniaturization, arraying, high brightness and low cost. At present, the existing Mini LED production lines in China are in the stage of technical research and development, and the supporting testing equipment manufacturers have not moved in on a large scale. The applied Mini LED testing equipment is partly imported, which is expensive and expensive. [0003] Therefore, how to provide a quality inspection of the MiniLED sheet during the production process is particularly important. SUMMARY OF THE INVENTION [0004] In order to solve the above technical problems, the pu...
