Camera module and camera module assembling method

Abstract

The invention discloses a camera module and an assembling method of the camera module. The camera module comprises a photosensitive component; a lens assembly including a lens carrier mounted on the photosensitive assembly and the optical lens supported in the lens carrier; the lens carrier comprises a photosensitive component and a lens component, the photosensitive component and the lens component are accommodated in the outer frame, and a preset gap communicated with the outside is formed between the outer frame and the lens carrier; the packaging part of the photosensitive component is provided with a gas escape channel which is concavely formed on the upper surface of the packaging part, a first port of the gas escape channel extends to and is communicated with the closed space, and a second port of the gas escape channel extends to the preset gap to be communicated with the preset gap; and the gas escape channel and the preset gap form a gas escape passage for communicating the closed space to the outside. Therefore, in the baking and curing process of the camera module, the internal and external air pressure balance of the camera module can be controlled, and the light filtering element is prevented from being damaged due to pressure unbalance.

Description

technical field [0001] The present application relates to the field of camera modules, in particular to camera modules and an assembly method thereof. Background technique [0002] The module assembly industry is a precision processing industry, and its product quality is related to many factors in its production and processing process. Failure to control any factor may seriously affect the quality of the module. For example, particle control in the production environment, here, Particles can be understood as dust or dirt in the production environment. If the particle control is not up to standard, it is very easy to cause black spots in the image of the camera module. This kind of defect is not allowed, and the module can only be scrapped or repaired. [0003] In addition to particles and other substances that will affect module assembly, there are other environmental factors that are difficult to observe, which will also affect module production to varying degrees, such a...

AI Technical Summary

Problems solved by technology

However, limited by the development trend of miniaturization of camera modules, it is difficult to increase the thickness of the color filter. If the air pressure is not well controlled during the production and preparation process, the color filter is easily damaged (for example, cracks or even broken).
