Large-size LCD panel inspection device

Abstract

The invention belongs to the technical field of liquid crystal panel detection and particularly relates to a large-size liquid crystal panel detection device. The large-size liquid crystal panel detection device comprises a machine frame, wherein a material conveying device, a CCD (Charge Coupled Device) camera moving device, a rotary table, material taking and placing devices and a controller are mounted on the machine frame; the material conveying device, the rotary table and an overturning mechanism are sequentially mounted on the machine frame in the axial direction; the CCD camera moving device is positioned below a supporting plate of the rotary table; the overturning mechanism comprises a plurality of overturning devices which are mounted on the machine frame, are positioned on two sides of the axial direction and are symmetrically distributed; a guide rail is axially arranged at the top of each of the overturning devices on the two sides of the axial direction on the machine frame; the material taking and placing devices capable of moving along sliding rails are mounted on the two guide rails respectively. The streamlined detection device is adopted, the working state of each device is controlled by the controller, transporting and overturning of a liquid crystal panel can be controlled, and the whole detection device is high in automation degree, easy to operate and high in detection efficiency.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal panel detection, and in particular relates to a large-size liquid crystal panel detection device. Background technique [0002] With the rapid popularization of LCD monitors and LCD TVs in recent years, consumers have put forward higher requirements for the size and quality of LCD panels, which requires relevant testing during the production process of large-size LCD panels to ensure that the products manufactured quality. The liquid crystal panel is at different angles, and the picture effect is different, so it is necessary to turn the liquid crystal panel at a certain angle to fully detect the picture. The existing liquid crystal panel detection device is a fixing device, which is used to fix the liquid crystal panel. During the detection, only one angle of the picture is detected, and the detection effect is poor. Moreover, there is no alignment device and handling device, and a large ...

Problems solved by technology

The existing liquid crystal panel detection device is a fixing device, which is used to fix the liquid crystal panel. During the detection, only one angle of the picture is detected, and the detection effect is poor. Moreover, there is no alignment device and handling device, and a large number of liquid crystal panels needs to be inspected. When detecting, the detection efficiency is low
