Light leakage detection device and method for camera testing, assembling and bonding

The invention relates to the technical field of camera processing and testing, in particular to a light leakage detection device and method for camera testing, assembling and bonding, and the device comprises an assembling and laminating machine which is fixedly provided with a testing graph card located above a loading platform of a lens group and a circuit board. A first light source and a plurality of second light sources are fixedly arranged on the assembling and laminating machine table, a light blocking area is arranged outside a preset range in the circumferential direction of the identification point, a processor is arranged on the assembling and laminating machine table, the processor obtains a test image from the camera module, and the processor judges the glue breaking condition and the shooting performance of the camera module according to the test image. A test graphic card provided with a light blocking area is used, light is irradiated from the upper portion of the test graphic card and the hor
