Device and detection method for detecting camera module along the horizontal direction

Abstract

A device for detecting a camera module along the horizontal direction and a detection method thereof. The detection device arranges a near-focus light source with a vertical extension direction, a teleconverter, a dirty point light source, and a far-focus light source along the horizontal direction. When the camera module is detected, the camera module is moved along the horizontal direction, so that the posture of the camera module is more suitable for the user to use the mobile electronic device with the camera module to shoot images When using the posture of the camera module, compared with the way of detecting the camera module along the longitudinal direction in the prior art, the detection result of the camera module by the detection device of the present invention is more in line with the actual situation.

Problems solved by technology

The equipment used to detect the camera module in the prior art is carried out manually, and the camera module is sequentially detected along the longitudinal direction for each focus position (including near focus, middle focus and far focus) and contamination of the camera module. In some cases, there are many problems in this detection method, which affect the detection effect and efficiency of the camera module.

[0005] Specifically, firstly, the inspection equipment in the prior art has only one inspection station, and requires the manual operation of the inspector, that is to say, the inspector can only test a single camera module at a time when inspecting the camera module. The method leads to low detection efficiency. For example, in the actual application process, the detection efficiency UPH (Units Per Hour) of the prior art detection method for camera modules is only 70pcs (Pieces, pieces)

In addition, when testing the camera module with the testing equipment of the prior art, the test seat used to fix the camera module needs to be manually rotated. Therefore, during the rotation, due to the accuracy of the equipment and the labor Due to reasons such as accuracy, the verticality of the test seat after being rotated cannot be guaranteed, so that the consistency of the test results for different camera modules is relatively poor

[0006] Furthermore, when the detection equipment in the prior art detects the near focus, middle focus and far focus of the camera module, the positions of the near focus light source and the far focus light source are fixed by magnets, so that when different camera modules are tested, each The positions of near focus, middle focus and far focus of a camera module cannot be guaranteed to be consistent

Especially when testing the telephoto of the camera module, the position of the teleconverter used to assist the testing process cannot be adjusted, and it is impossible to ensure that the central axis of the teleconverter is aligned with the central axis of the camera module

In addition, the inspection method of the inspection equipment in the prior art for the camera module is carried out along the longitudinal direction, so a working channel needs to be reserved on the upper part of the inspection equipment, so that the light from the external environment can easily enter the interior of the inspection equipment through this working channel , and cause interference to the detection light source, so the semi-closed design scheme leads to poor detection effect of the detection equipment in the prior art

And the function of the detection equipment of prior art is relatively single, can't general AF (Auto Focus, automatic focus) burning and AF detection
