Abstract

The invention discloses a method and device for online quality detection of a display panel. The method includes the following steps: setting glass substrate random inspection parameters for each link in a process on a manufacturing execution system, and transmitting the random inspection parameters to an assembly line control system; The pipeline control system receives and stores the random inspection parameters; the pipeline control system generates a random inspection control signal according to the random inspection parameters and sends it to the machine, so that the machine performs a random inspection operation according to the random inspection control signal. The technical scheme of the online quality detection method of the display panel of the present invention conducts precise sampling inspection on each link of the production process through the centralized setting of the manufacturing execution system, and improves the yield rate and detection efficiency of the glass substrate.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a method and device for online quality detection of a display panel. Background technique [0002] The glass substrate is an important part of the liquid crystal display panel, and its quality is crucial to the display effect of the display panel. Strict quality control is required at each stage of the coating process for glass substrates. According to different products on the assembly line, corresponding sampling inspection rates need to be set. However, most of the existing inspection methods are for sampling inspection of the finished products at the end of the production line, and it is impossible to carry out accurate sampling inspection for the semi-finished products in each link of the process, which affects the product quality and inspection efficiency. Contents of the invention [0003] The main purpose of the present invention is to provide an on-line quality inspe...
