Description

Camera module testing platform and testing method

Technical Field

The invention relates to the field of camera module testing, in particular to a camera module testing platform and a testing method.

Background

The camera module is modularized equipment integrated with a camera device and related circuits, is generally used for adding image and video capturing functions into various electronic equipment, such as a smart phone, a tablet personal computer, a notebook computer, a video camera, an unmanned aerial vehicle and the like, and in the production process, in order to ensure that the camera module can work normally, a large number of camera modules need to be tested after production is finished, such as a power-on test, an image test, an exposure white balance test, a high-low light environment test, a focusing test, a high-low temperature environment test, an electrostatic test and the like, so that whether the quality of the camera module meets the standard is verified, and the existing testing device can only test a single camera module in a single type or a single type, and has low efficiency.

Along with the progress of technology, the related art technicians also optimize the testing process of the camera module, for more accurate comparison, for example, chinese patent publication No. CN116233408A discloses a camera module optical testing platform and testing method;

when the camera module is used, the arc-shaped rail is driven to rotate through the driving mechanism, the shooting target piece is driven to synchronously rotate along with the arc-shaped rail, the shooting target piece and the arc-shaped rail are arranged relatively, the transmission mechanism drives the shooting target piece to reciprocate transversely relative to the arc-shaped rail during rotation, so that the far and near test of the camera module is realized, and meanwhile, the camera module automatically slides downwards along the arc-shaped rail, namely, the shooting angle of the shooting target piece continuously changes, namely, the multi-angle continuous test is met, and the far and near test and the multi-angle test are completed together.

However, when the above prior art is adopted to test the camera module, there are also the following problems:

1. the device can test the camera module, the disposable test quantity is too small to meet the test requirement of a large batch, and the same type of test can be only carried out on the camera module in the test process, so that the device can only adapt to a small number of test scenes, and has low applicability.

2. After the camera module is tested, the camera module which is qualified and unqualified in test is still mixed together, the camera module and the camera module are manually distinguished, the test efficiency is greatly reduced, the device does not have equipment capable of uniformly clamping the camera module, and the device is relatively troublesome in placing and taking out the camera module.

3. Although the device can carry out the optical test to the angle to the camera module, but can not provide a good test environment to the testing device in the test process, the device is easy to be influenced by external factors in the test process, so that the final test is caused, the camera module is tested in a deflection mode, the middle module can only be accurately tested, the modules at two sides can not be effectively tested due to the problem of angle deviation, and the device can only test a part of the modules at one time.

Therefore, in view of the above, there is still room for optimizing the test mode of the camera module in the prior art.
