Camera module and its structure and assembly method

Abstract

A camera module and its structure and assembly method, wherein the camera module includes a motor lens component and a circuit assembly; the motor lens component is located on the front side of the circuit assembly, so that the light passing through the motor lens component reaches The circuit assembly, and the motor lens component is welded to the circuit assembly. The camera module assembly method includes the steps of: (A) dynamically adjusting a motor lens component; (B) welding the motor lens component to a circuit assembly.

Description

technical field [0001] The present invention relates to the field of camera modules, and further relates to a camera module and its structure and assembly method. Background technique [0002] In recent years, with the rapid development of smart phones, the demand for mobile phone cameras is increasing day by day, and the competition of camera modules is becoming increasingly fierce, and the structure and performance of camera modules have been greatly developed. [0003] The basic performance, structure and manufacturing process of the constituent elements of the camera module are important factors for determining the camera parameters of the camera module. Therefore, overall, the improvement of the camera module tends to these three major aspects, and these aspects are interrelated and influenced. [0004] In the existing technology, on the one hand, the basic performance of components, such as manufacturing materials, etc., has been developed to a relatively high level, ...

AI Technical Summary

Problems solved by technology

As camera modules increasingly require high-resolution, large-diameter lenses, the requirement for glue space makes it difficult to reduce the bonding surface of the lens holder and horse lens components. Therefore, the existing structure obviously cannot meet the needs of camera modules needs

[0008] Secondly, since the AA process requires dynamic correction to reserve a wider glue space, it is necessary to apply thicker glue when AA glue is applied than the traditional paste method, which not only increases the production cost, but also increases the amount of glue Difficulty of control

If the amount of glue is too large, the product will have serious glue overflow, which needs to be scraped off later, and the lens will be easily contaminated; if the amount of glue is small, the bonding reliability of the camera module will be poor, and the motor will easily shake or fall off.

[0009] Third, after the glue coating is completed, two steps of glue pre-curing and oven baking and curing are still required to basically complete the assembly of the camera module, that is, the AA process, which makes the overall process more steps and requires a lot of time. time, and therefore less productive

[0010] Fourth, due to the characteristics of the glue itself, on the one hand, the bonding strength is poor, and it is easy to loosen when subjected to a large external force; on the other hand, it is easily affected by the ambient temperature, and it is easy to deform when the temperature changes. and affect the optical performance of the camera module

[0011] It can be seen from this that for the AA glue assembly method in the prior art, many unfavorable factors have been produced while improving the performance of the camera module through the AA process, which limits the further development of the camera module.
