Test tool for camera module test, application and test method thereof

Abstract

The present invention discloses testing equipment for a camera module test. The testing equipment comprises a substrate, a light-through hole formed in the substrate and a shield switching device, wherein the shield switching device is used for shielding or avoiding the light-through hole; the shield switching device comprises a switching bearing plate, a switching baffle plate, a circular magnet and a coil; the circular magnet is arranged on the switching bearing plate through a positioning column; the coil is located above the circular magnet; the switching bearing plate is connected with the circular magnet through a lifting lever; the coil is used for driving the circular magnet to rotate around the positioning column, to drive the switching baffle plate to move to shield or avoid the light-through hole. The testing equipment for the camera module test is integrated with the shield switching device, can intelligently shield and avoid the lens light-through hole of a camera, thereby achieving the function of automatically switching between a bright environment test and a dark environment test of images, improving the production efficiency and reducing the production cost; and the testing equipment is featured with a simple structure and a small size, and is used together with current focusing or testing equipment and the like, thus, the application range and use efficiency can be improved and excellent economic benefits are achieved.

Description

technical field [0001] The invention relates to the field of cameras, in particular to a test tool for camera module testing, an application thereof, and a testing method using the test tool for camera module testing. Background technique [0002] At present, electronic devices (such as mobile phones, tablets, etc.) are equipped with cameras. In the actual production process, various functional tests of the cameras are required. Among them, the test of bright environment and dark environment is an important parameter in the test of camera modules, such as Bright spot test, bad line test, dark current test and other tests need to be tested in a dark environment where the screen is completely dark. In the existing bright environment and dark environment switching test camera modules, the usual practice is to manually cover the blackboard to block the lens light hole or use a closed box to cover the camera module so that the image of the camera module is completely black. , so...

Problems solved by technology

Among them, the manual cover method is not conducive to automatic production; at present, more methods such as closed box cover and driving mechanism are used on other auxiliary equipment to realize dark environment, but the implementation on auxiliary equipment is more complicated, the volume is larger, and the cost is relatively high. High, and cannot be shared with current focusing or testing equipment, limiting its applicability and efficiency
