Detection device for detecting front and back surfaces of liquid crystal panel

Abstract

The invention discloses a detection device for detecting the front and back surfaces of a liquid crystal panel. The detection device comprises an operating platform body, a bearing pallet, a first line array camera, a loading and moving device and a second line array camera, and further comprises a first lighting unit and a second lighting unit, wherein the loading and moving device comprises a bracket unit and a vacuum adsorption board used for loading the liquid crystal panel to be detected; the vacuum adsorption board is movably arranged on the bracket unit. The detection device has the advantages that appearance detection of the front and back surfaces of the liquid crystal panel can be realized automatically in one step; suitability for liquid crystal panels of various dimensions is realized; manual appearance detection working stations are completely eliminated during liquid crystal panel detection; various appearance defects such as notches, breakup, burrs, fracture and metal corrosion on the appearance of the liquid crystal panel can be detected effectively and fast.

Description

technical field [0001] The invention relates to a liquid crystal panel appearance detection device, in particular to a detection device for detecting the front and back of the liquid crystal panel. Background technique [0002] With the rapid development of digitalization of consumer electronics such as mobile communication equipment, GPS (satellite navigation equipment), digital products, computers, TVs, MP4, etc., liquid crystal displays can be seen in the above-mentioned various types of products. [0003] Among them, the production of LCD panels needs to go through multiple processes. During the processing, various defects may occur. In order to obtain the final products that meet the quality specifications, it is necessary to carry out defect detection of LCD panels in all links of the outflow of finished products and / or semi-finished products. Appearance (APP) defects are one of the most important types; after the cutting, cracking, and filling processes of the LCD pan...

Problems solved by technology

[0004] And this work so far, no matter in the liquid crystal giant SHARP, Samsung, or other manufacturers of second-tier brands, it is purely manual to complete the appearance inspection of LCD panels. The workers need to have certain defect identification capabilities, so it is necessary to The workers at each inspection station undergo strict training, which is expensive, time-consuming and labor-intensive; and the efficiency of manual inspection is low, especially after working for a long time due to eye fatigue and prone to missed judgments.
