Embodiment Construction

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] In the prior art, when performing a focusing test method on a CCM, it is necessary to paste a two-dimensional code on the surface of the CCM as a mark. The test judgment result is stored corresponding to the two-dimensional code. In the OTP burning stage, it is necessary to scan the two-dimensional code of the CCM to be tested with a two-dimensional code scanning device again, so as to correspondingly save the OTP burning judgment result and the two-dim...

Abstract

The invention discloses a test method, test system and test device of a micro camera module. The test method comprises the steps that a CCM to be tested is subjected to a focusing test so that focusing test data can be obtained, and whether the focusing test of the CCM to be tested is qualified is judged according to the focusing test data; a judgment result of the focusing test of the CCM to be tested and a serial number of a sensor of the CCM to be tested are correspondingly stored in a test database; when the judgment result of the focusing test is qualified, the CCM to be tested is subjected to OPT programming to obtain OTP programming data; whether the OTP programming of the CCM to be tested is qualified is judged according to the OTP programming data; the judgment result of the OTP programming of the CCM to be tested and the serial number of the sensor are correspondingly stored in the test database; when the judgment result of the OTP programming is qualified, it is determined that detection of the CCM to be tested is qualified. The testing process of the technical scheme is simple, and testing efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of camera preparation, and more specifically, relates to a testing method, a testing system and a testing device for a miniature camera module. Background technique [0002] In recent years, with the development of multimedia technology, the application range of CCM (Compact Camera Module, miniature camera module) has become wider and wider, and is widely used in electronic products such as mobile phones, computers, and miniature cameras. [0003] refer to figure 1 , figure 1 It is a schematic structural diagram of a CCM, and the CCM includes: a control board 1 , a voice coil motor 2 (VCM, Voice Coil Motor) and a lens 3 . Wherein, the control board 1 includes: a sensor with an internal memory. CCM needs to perform focusing test and OTP burning test. [0004] The traditional CCM test method realizes the storage of the corresponding test results by pasting a QR code on the CCM to be tested. In this way, i...
