Abstract

The invention provides a pre-positioning device for panel AOI (automatic optical inspection), which relates to the technical field of panel defect detection. The device comprises a clamping mechanism, a first movable support arranged on the clamping mechanism and a first fixed support arranged opposite to the first movable support along a first direction. The first movable support and the first fixed support are each provided with a first positioning roller, at least one of the first positioning roller of the first movable support and the first positioning roller of the first fixed support is suitable for moving towards the other one so as to correct the to-be-detected panel, and the clamping mechanism is used for driving the corrected to-be-detected panel to move. The first movable support is arranged on the clamping mechanism, so that after the pre-positioning device completes positioning, the clamping mechanism can clamp the to-be-detected panel without moving, the time of moving the clamping mechanism to the position below the first movable support is saved, and the panel detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of panel defect detection, in particular to a pre-positioning device for panel AOI detection. Background technique [0002] At present, many defects may occur in the manufacturing process of liquid crystal display panels. These defects can be roughly divided into macroscopic defects and microscopic defects. Microscopic defects are difficult to detect with the naked eye. Therefore, it is necessary to use optical detection and machine vision algorithms to automatically detect panel defects. , This method is usually called AOI inspection, the full name is Automated Optical Inspection (Automated Optical Inspection), and the equipment using this testing technology is called AOI inspection equipment. [0003] In the existing AOI inspection equipment, when the panel is transported from the previous station to the AOI inspection equipment, due to the different positions of the panel during loading, it is often neces...
