Shading mechanism and glass substrate detection device

The invention relates to a shading mechanism and a glass substrate detection device. The shading mechanism is used for being arranged at the entrance of a glass substrate of a glass substrate detection chamber. The shading mechanism comprises a shading plate (1). The shading plate (1) can move between a working position and an idle position. The shading plate (1) completely blocks the entrance ofthe glass substrate at the working position and avoids the entrance of the shading plate (1) at the idle position. Through the technical scheme, the shading mechanism provided by the invention can provide a dark environment for detection of the glass substrate and is beneficial for keeping the cleanliness of the detection chamber. 本公开涉及一种遮光机构和玻璃基板检测设备，所述遮光机构用于设置在玻璃基板检测室的玻璃基板入口处，所述遮光机构包括遮光板(1)，该遮光板(1)能够在工作位置和闲置位置之间移动，在所述工作位置，所述遮光板(1)完全遮挡所述玻璃基板入口；在所述闲置位置，所述遮光板(1)避让所述玻璃基板入口。通过上述技术方案，本公开提供的遮光机构能够为玻璃基板的检测提供黑暗环境，同时还有益于保持检测室内的洁净度。
