Problems solved by technology
The vision test is to simulate the state of infinity. The vision test of the general module factory is to shoot the real scene in the distance. Due to the inconsistency of the external environment, vision, and testers, the vision test is often not standardized, and the quality cannot be well controlled. Guaranteed, mass production not possible
Therefore, the use of existing assembly and testing processes will not be able to meet the requirements of AF mobile phone module manufacturing

Embodiment Construction
[0021] As shown in the figure: a test light tube is set on one side of the standard test light box, and a standard image m is set on the other side; the test light tube p is an optical system that can simulate infinity, including the optical system located in the lens barrel q The lens positioned by the spacer u, the lens from one end to the other end of the barrel q is a crescent concave lens r, a double concave lens s and a convex lens t.
[0022] The test device also includes a focus ring g. When in use, the focus ring g is positioned on the same axis as the test light tube p and the standard image m, and is positioned outside the test light tube p; during testing, the focus ring g The bayonet on the head is plugged into the clip on the head of the lens a in the camera module to be tested.
[0023] Described testing device also comprises test board k, has two buttons h, j and the position that is used to install flexible circuit board f at one end of this test board k, has ...

The invention relates to a method for testing a camera module of a mobile phone, in particular to a method for testing a camera module of a mobile phone with an automatic focusing function. According to the technical scheme provided by the present invention, according to the technical scheme provided by the present invention, a test light tube is set on one side in the standard test light box, and a standard image m is set on the other side; the test light tube p is a can simulate infinity The optical system includes a lens located in the lens barrel q and positioned by a spacer u, and the lenses are crescent concave lens r, double concave lens s and convex lens t from one end to the other end of the lens barrel q. The present invention utilizes a focusing test light tube capable of simulating the scene at infinity, and carries out the vision test in the standard test light box, so as to improve the consistency of the quality of the AF camera module and the yield rate of the product.
Description
technical field [0001] The invention relates to a testing method for a mobile phone camera module, in particular to a testing device and a testing method for a mobile phone camera module with an automatic focusing function. Background technique [0002] With the gradual popularization of camera phones, camera phones with automatic focusing function Auto Focus, referred to as AF, are rapidly expanding their market share, especially in the field of high-pixel mobile phones, AF has become a trend to replace fixed-focus camera phones. AF camera phones are different from fixed-focus camera phones in that their camera modules have an AF function, that is, there is a device in the module that can automatically adjust the axial position of the lens, which is called auto-focus. Generally, the function of this device is performed by a motor, such as a traditional electromagnetic / stepper motor and Voice Coil Motor, VCM, etc. The focusing process is realized by driving the motor throug...
