Abstract

The invention relates to shading equipment for panel detection. The shading equipment comprises a bracket, two shading modules and a positioning seat, the two shading modules are arranged on one sideof the bracket and can get close to or get away from each other, and each shading module comprises a shading assembly, a driving device and a corner positioning piece; the driving device is used for driving the shading assembly to slide; each shading assembly comprises a supporting beam and a shading plate, and the shading plate is fixed to the supporting beam; the corner positioning pieces are fixedly arranged on the supporting beams; the positioning seat is fixed to the side, away from the shading modules, of the bracket and provided with an ejector plate, and the ejector plate matches the corner positioning pieces to be used for positioning a panel; and a detection space for a light source of an external backlight to pass through is formed between the two shading plates. According to the shading equipment for panel detection, panels of different sizes can be rapidly and accurately positioned, and the irradiation range of lamplight of the backlight is adjusted.

Description

technical field [0001] The invention relates to the technical field of optical detection equipment, in particular to a light-shielding device for panel detection. Background technique [0002] Before leaving the factory, many products such as liquid crystal displays (that is, liquid crystal panels) need to be inspected to determine whether the quality is qualified. The current detection method for liquid crystal display screens is to use the backlight to observe whether there are quality problems in the liquid crystal display screen. [0003] The Chinese utility model patent with the notification number CN209821546U discloses a detection device for a liquid crystal display, including a bracket, an L-shaped workbench arranged on the bracket, a backlight arranged on the vertical side wall of the workbench, and two opposite A light-shielding plate on the upper surface of the horizontal end of the workbench is provided. The vertical end of the workbench and the top of the side ...
