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 horizontal direction of a
camera module, the camera module shoots a test image of the test
graphic card, and meanwhile light leakage detection and shooting performance detection are carried out. According to the invention, the glue breaking and light leakage conditions and the shooting performance of the camera module are tested at the same time, and the testing procedures of the camera module are reduced.
