The invention relates to an LCD light leakage detection mechanism. A lifting adjusting mechanism and a rotating disc mechanism are installed on a bottom plate. Carrier devices are installed on the rotating disc mechanism. A CCD supporting bottom plate of a CCD adjusting mechanism is connected with nuts on a left lead screw and a right lead screw of the lifting adjusting mechanism. The CCD supporting bottom plate of the CCD adjusting mechanism is fixedly connected with an upper seal box of a seal box mechanism through four reinforcement ribs, the CCD adjusting mechanism is used for adjusting the vertical height of a CCD, the seal box mechanism is used for guaranteeing that an LCD is always in a closed and light-proof environment, and the lifting adjusting mechanism is used for adjusting the vertical height of the CCD adjusting mechanism and the seal box mechanism. A taking and placing station and a detection station are arranged on a rotating disc of the rotating mechanism, the carrier devices are installed on both the stations respectively, the two stations can achieve continuous detection, and whether the LCD leaks light or not is detected through CCD photographing. The LCD light leakage detection mechanism is simple in structure, convenient to operate and capable of rapidly and accurately detecting whether the LCD leaks light or not.
