Abstract

The invention relates to the technical field of automatic optical liquid crystal panel detection, in particular to a double-station offline detecting system and method of a liquid crystal panel. The system comprises an image collecting module, a defect defecting module, a master control module, a first motion unit and a second motion unit. The first motion unit comprises a first movable mechanism, a first image signal generator and a motor, and the second motion unit comprises a second motion mechanism, a second image signal generator and a motor. The first motion mechanism and the second motion mechanism are arranged on two parallel guide rails respectively, the motors are fixed to the two ends of each guide rail, the first movable mechanism and the second movable mechanism can be controlled to do horizontal reciprocating motion along the guide rails under the control of the motors, and when one motion unit is located on a detection station, the other motion unit is located on a waiting station. Two offline stations are adopted, one motion unit waits for screen mounting of an operator, the other motion unit carries out automatic detection and display, time is reasonably planned, and equipment productivity is improved.

Description

technical field [0001] The invention relates to the technical field of automatic optical liquid crystal panel detection, in particular to a dual-station liquid crystal panel off-line detection system and method. Background technique [0002] Nowadays, liquid crystal panels are widely used in the display field of electronic products, and the factory yield rate of their products is the basis for the survival of liquid crystal display manufacturers in today's fierce competitive environment. In all links of its production and production, quality inspection is an important link to ensure the quality of LCD panel products. The traditional production line manually clicks on the screen and cuts pictures, and the inspection method of visually finding defects relies too much on the subjectivity of workers, which has the potential for false detection and missing. With the continuous development and application of automatic optical technology, the automatic optical inspection system bas...
