Optical detection equipment and method for liquid crystal display modules

Abstract

The invention discloses optical detection equipment for liquid crystal display modules. The optical detection equipment comprises an equipment body, a four-station rotary device, a double line scanning camera mechanism and a plane scanning camera mechanism, wherein the four-station rotary device comprises a rotary plate; a line scanning detection station, a feeding station, a plane scanning detection station and a plane scanning detection code spraying station are arranged on the four-station rotary device and circumferentially distributed along the center of the rotary plate; synchronous adjustment mechanisms used for simultaneously detecting the two liquid crystal display modules are correspondingly mounted on the stations of the four-station rotary device respectively. According to the optical detection equipment, the detection efficiency of the liquid crystal display modules can be improved, the liquid crystal display modules can be simultaneously detected, the detection rate is high, the parallelism of the liquid crystal display modules and camera lenses can be guaranteed, and the image quality requirements of camera detection and shooting can be met.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display module detection, in particular to an optical detection device and method for a liquid crystal display module. Background technique [0002] For the detection of liquid crystal display modules, a single camera is generally used to take pictures. Since the defects on both sides of the liquid crystal display module need to be detected, this will lead to a long empty travel of the camera, a long cycle, and low efficiency, which cannot meet the production requirements at all. Beat requirements, for the general four-station rotary platform or multi-station rotary platform, lack of a lifting platform, it is difficult to meet the positioning requirements, and the rotary platform is required to have high machining accuracy, and the workpiece is difficult to process, which cannot meet the accuracy requirements. [0003] Therefore, those skilled in the art have been devoting themselves to dev...
