Abstract

The invention discloses a photosensitive module testing device, and relates to the technical field of optical testing. The testing device comprises a bottom plate, and a height adjusting assembly anda horizontal adjusting platform which are arranged on the bottom plate. A test fixture is arranged on the horizontal adjusting platform and used for fixing a to-be-tested photosensitive module. The height adjusting assembly is provided with a rotating support rotationally connected with the height adjusting assembly. A blackboard and a light source with uniform illumination are respectively arranged on the rotary support; the light source or the blackboard corresponds to the to-be-tested photosensitive module when the rotary support is rotated, and the photosensitive module testing device further comprises a testing assembly which is electrically connected with the photosensitive module to be tested and used for testing the to-be-tested photosensitive module. The test form of the photosensitive module can be simplified, the detection efficiency is improved, the operation difficulty and the operation intensity are reduced, and the production cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of optical testing, in particular to a photosensitive module testing device. Background technique [0002] With the development of multimedia technology and electronic technology, photosensitive modules are widely used in mobile phones, computers, door locks and other electronic products. The demand for various types of photosensitive modules is increasing, and certain test indicators must be met accordingly. For example, the 3D structured light receiving end Rx module or RGB lens module in the photosensitive module mainly tests the sharpness, optical center, dirt and dead pixels and other test items. [0003] Among the above test items, a uniform light source (uniformity > 95%) is required for the test of the optical center and dirt, and a blackboard (black non-reflective material) is required for the dead pixel test. During the test, moving the uniform light source directly above the photosensitive mod...
