Abstract

The application discloses a glass transmittance detection device, which comprises a first adjusting unit and a second adjusting unit. The first adjusting unit comprises a variable amplitude rod and a detection chamber rotatably connected to the end of the variable amplitude rod. The second adjusting unit comprises a variable amplitude plate and a detection chamber slidingly arranged on the variable amplitude plate. One end of the variable amplitude rod and the variable amplitude plate is driven to move up and down, and a rotating torque is applied to the driven end of the variable amplitude rod and the variable amplitude plate to make the detection chamber adhere to the glass to be detected. The first adjusting unit and the second adjusting unit each comprise a plurality of detection chambers, and the detection chamber is provided with an emitting module and / or a receiving module. The application combines the structure of the rotating connection and the sliding connection, cooperates with the self-adaptive force provided by the tension spring, realizes the automatic profiling and adhering detection of the curved windshield of the automobile, solves the problem of the tight adhesion and the light path deviation caused by the curvature difference of the glass in the online detection, and significantly improves the detection precision and the automation degree.
