Beschreibung
Zusammenfassung:	The screen detection device comprises a detection platform and a detection mechanism, the detection mechanism comprises a first detection module, a second detection module, a first driving assembly, a module fine adjustment assembly and a light source, and the module fine adjustment assembly is used for driving the first detection module to move in the Y direction and driving the first detection module to rotate around the X direction; the first detection module comprises a camera, an upper polaroid and a second driving assembly used for driving the upper polaroid to rotate. The second detection module comprises a lower polaroid and a third driving assembly used for driving the lower polaroid to rotate. According to the utility model, the second driving assembly and the third driving assembly are arranged and can respectively drive the upper polaroid and the lower polaroid to rotate around themselves, and the included angle between the polarization axis of the upper polaroid and the polarization axis of the l
