Abstract

The invention relates to an optical automatic detection device for a display panel, and belongs to the technical field of optical detection of liquid crystal displays, and the optical automatic detection device comprises a darkroom detection box, the front surface of the darkroom detection box is provided with a window for taking and placing a detected product, and the window is provided with a closing door for closing the window; the product lifting platform comprises a lifting platform body which moves up and down along the Z axis, and the lifting platform body is provided with a product carrying platform for fixing a tested product and a circuit board for lightening the tested product; the optical detection platform comprises a camera platform which is located above the product lifting platform and moves up and down along the Z axis, and the camera platform is provided with a camera for collecting image information of a detected product; and the diffusion plate assembly comprises a diffusion plate arranged between the lifting platform and the camera, and an overturning rack for driving the diffusion plate to be converted in the horizontal direction or the vertical direction. According to the invention, automatic high-quality detection of the detected product is realized, the product quality is ensured while the cost is reduced, and the product detection efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of display optical detection, and in particular, to an optical automatic detection device for a display panel. Background technique [0002] In recent years, monitors have been widely used in daily life, the market demand is large, and the production volume is also large. The monitor needs to be tested before leaving the factory to see whether it can be used normally and whether the screen linearity meets the standard. Slow, still retains the visual detection method of the human eye, and the detection of automated equipment is almost zero. [0003] With the upgrading of the industry, the drawbacks of visual inspection by the human eye have become increasingly prominent, which are mainly reflected in: the low accuracy of manual inspection, the certain error in the inspection results, the improvement of the technology level and the inspection accuracy, and the human eye is no longer suitable for high...
