Coding abnormity judgment method and device, storage medium and terminal

Abstract

The invention provides a coding abnormity judgment method and device, a storage medium and a terminal. The coding abnormity judgment method is applied to a coding machine, wherein three encoders, on the x axis, of the coding machine are correspondingly provided with three pulse signal generators; the method comprises the following steps that positional information of the three encoders on the x axis is received; pulse signals generated by the three pulse signal generators corresponding to the three encoders are received, and when each encoder moves on the x axis with preset distance, the corresponding pulse signal generator generates a pulse signal; whether or not the number of the pulse signals corresponding to the three encoders and the positional information meet a preset demand is judged respectively; if not, it is judged that coding is abnormal. The coding abnormity judgment method and device, the storage medium and the terminal can improve the product percent of pass.

Description

technical field [0001] The present application relates to the field of liquid crystal production, and in particular to a method, device, storage medium and terminal for judging coding abnormalities. Background technique [0002] In recent years, small and medium-sized liquid crystal displays have developed rapidly. During the LTPS process, a coding machine is required to identify a single chip in the array factory and the subsequent process. At present, there have been many occurrences of title coding machines in the factory during the coding process. The lack of code caused the chip to be unrecognizable, and the substrate was scrapped after the abnormal chip flowed out of the station. [0003] Therefore, there are defects in the prior art, and improvement is badly needed. Contents of the invention [0004] The embodiment of the present application provides a coding abnormality judgment method, device, storage medium and terminal, which can improve the qualified rate of p...
