Light box for testing image pickup module set and assembly method of light box

Abstract

The present invention discloses a light box for testing an image pickup module set. The light box comprises a light box shell, a light source and a plurality of test calibration target layers; the light source is arranged in the light box shell; each test calibration target layer is arranged in the light box shell along a depth direction; each test calibration target layer is provided with at least one test pattern; the test patterns of any one of the test calibration target layers are not overlapped with the test patterns of the other test calibration target layers in the depth direction; and light generated by the light source is radiated through each of the test calibration target layers.

Description

technical field [0001] The invention relates to the field of testing of optical imaging devices, in particular to a light box for testing a camera module and an assembly method thereof. Background technique [0002] In recent years, the camera module used to acquire images, as the carrier of human visual extension, has gradually become the standard configuration of electronic equipment, especially in the field of portable electronic equipment represented by smart phones, tablet computers, etc., the camera module is more Has been widely used. As users have more and more stringent requirements for the imaging quality of camera modules, the relevant technologies of the camera module industry have also developed by leaps and bounds, and the camera module industry has also continuously developed automation equipment that requires different functions. , Participate in the production and testing process of camera modules. [0003] For example, when testing the imaging quality of ...

Problems solved by technology

Such an assembly method has many defects. First, there is no reference coordinate between each test pattern of the same layer of test plates, resulting in insufficient precision of the test plates, which will affect the test effect of the camera module. For example, the test plate There may be a tilting phenomenon; secondly, there is no corresponding benchmark between each layer of test plates, which makes it difficult to adjust the test plates of each layer, which affects the adjustment speed of the test machine. Assembling and zooming in will take a long time. In the actual operation process, through the statistics of the time spent in the assembly process of the traditional light box, it will be found that the traditional light box requires at least two people to cooperate with each other and takes two days to complete.
