Lens module assembling process

Abstract

The invention relates to a lens module assembling process. The process comprises the following steps that a lens holder and filter glass are assembled to form a first assembly; a lens and a voice coil motor are assembled to form a second assembly; the first assembly and the second assembly are assembled to form a whole assembly; a lens module is formed by assembling the whole assembly and a printed circuit board. According to the lens module assembling process, the holder and the glass are combined into a whole in advance, the VCM and the lens are combined into a whole in advance, integrated production is conducted, dispersibility of the process is reduced, time for exposing the filter glass in air is shortened, the probability of pollution of the glass is reduced, the phenomena of center bias of the optical axis and poor inclination are reduced, quality and efficiency are improved, and cost is reduced.

Description

technical field [0001] The invention relates to a lens module assembly process. Background technique [0002] The lens module is an optical component used to generate images, consisting of a lens (Lens), a voice coil motor (VCM), a mirror holder (Holder), a filter lens (Glass), an image sensor (sensor), a printed circuit board (PCB) , connectors, and peripheral electronic devices, and are widely used in camera and photographing of mobile electronic devices. The invention mainly explains the new assembly process of PCB, Lens, VCM, Holder and Glass. [0003] The existing lens module assembly procedure is to assemble the Holder+Glass on the printed circuit board first, and then assemble the VCM+Lens assembly after the inspection is completed. The disadvantages of the process are: [0004] 1) The assembly process is scattered, and the material transfer process is easy to hide particles, which is difficult to clean and affects the assembly quality; [0005] 2) The assembly pro...

AI Technical Summary

Problems solved by technology

[0004] 1) The assembly process is scattered, and the material transfer process is easy to hide particles, which is difficult to clean and affects the assembly quality;

[0005] 2) The assembly process is scattered, and the manpower input of the machine is increased, resulting in an increase in operating costs;

[0006] 3) During the assembly process, the filter lens is exposed to the air for too long, which is easily polluted and difficult to clean, which affects the assembly quality;

[0007] 4) The mechanical design of the product only guarantees the accuracy for the Z-axis direction, the X / Y direction is not designed for close fit, and there is no Location for positioning on the combined product. The assembly process requires high equipment accuracy, resulting in increased equipment costs

[0008] Lens+VCM is assembled by aligning the center of the Sensor and the center of the Lens. During assembly, Holder+Glass is sandwiched in between, which is prone to misalignment of the optical axis center and poor tilt, resulting in product scrapping
