Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mobile phone camera module manufacturing, in particular to a testing device for light-shielding components. Background Art
[0002] With the advancement of technology, the requirements for mobile phone camera effects are relatively higher. Therefore, as a mobile phone manufacturer, after the assembly of the mobile phone camera module is completed, various tests will be carried out, including different light and dark environments, different temperature spaces, etc.
[0003] In daily life, mobile phones are frequently used to take photos in dark environments. Therefore, when we test the functionality of camera modules, the dark environment test of mobile phone camera modules is particularly important because light has a direct impact on imaging effects.
[0004] The shooting module is placed in an absolutely dark environment, using specific reference objects for taking photos. Finally, based on the analysis of specific software, it is determined whether the functional standards of the camera module meet the requirements. During the test, it is crucial to prevent the penetration of external light sources.
[0005] The shading method currently used on the market is a nozzle device, which is installed on the cylinder to perform pneumatic up and down shading functions, but shading has disadvantages. First, due to size limitations, the shading nozzle cannot cover multiple test targets; second, after the equipment is equipped with upright cylinder accessories, it occupies a large amount of vertical test space, and it is impossible to perform multiple project combination tests at the same workstation; third, because the shading nozzle is made of rubber, it has a short lifespan. After damage, it is easy for light to intrude and destroy the test environment, causing misjudgment of the test results; fourth, due to the electrostatic adsorption properties of the rubber material itself, during the operation of the equipment, the vibration of the equipment will drive the dust particles on the shading nozzle and float them in the internal space of the equipment, which will cause pollution to the lens surface of the camera module and affect the final test results. Therefore, we propose a test device for shading components. Utility Model Content
