The invention relates to the technical field of
liquid crystal display detection, in particular to a
liquid crystal display detection device which comprises a dust-free box, the dust-free box is composed of an upper cavity and a lower cavity, material taking assemblies are arranged on the inner walls of the two sides of the upper cavity, a bearing plate is fixedly connected to the rear wall of the interior of the upper cavity, and a transmission
assembly is fixedly connected to the top of the bearing plate. An angle adjusting
assembly is arranged between the inner walls of the lower cavity, and three visual cameras and a cleaning eraser are arranged at the bottom of the side, close to the front wall of the upper cavity, of the bearing plate. According to the improved detection device, through mutual cooperation of the angle adjusting
assembly and the transmission assembly,
liquid crystal display conveying and automatic angle adjustment are achieved, angle detection is more comprehensive, omission and detection dead angles are reduced, materials are taken and placed through the material taking assembly, the
liquid crystal display is taken into the dust-free box for detection, and the detection efficiency is improved. Dust is prevented from being attached to the cleaned liquid
crystal screen again to affect detection, the whole process is completely and automatically carried out, and the
automation degree is high.
