Camera module, manufacturing method thereof, and electronic product

Abstract

The invention discloses a camera module and a manufacturing method thereof as well as an electronic product. The camera module is used for the electronic product with a camera function and comprises a lens unit, a lens combination seat, a light filter, an image sensing chip and a substrate, wherein the surface, which is stuck to the lens combination seat, of the light filter is provided with a non ink region and an ink region surrounding the non ink region; the light filter is stuck to a flange in the inner cavity of the lens combination seat; a gluing setting region and a gluing blank region are formed at the edge of the ink region corresponding to the surface of the flange; the gluing setting region is coated with glue with a first thickness; a slotted exhaust structure with the first thickness is formed in the gluing blank region. An escape hole is not needed to be formed in the lens combination seat, so that human and material resources are reduced; the phenomenon that the imaging quality of the camera module is affected as impurities in air fall into the camera module when the escape hole is closed is also avoided.

Description

technical field [0001] The invention relates to the technical field of electronic products with a camera function, in particular to a camera module, an electronic product with the camera module and a method for manufacturing the camera module. Background technique [0002] As more and more electronic products are integrated with a camera function, it is particularly important to improve the performance of the camera module. [0003] like Figure 1-Figure 3 As shown, the camera module in the prior art usually includes a lens assembly base (referred to as the mirror base) 1 , a lens unit 2 , a filter 6 , an image sensor chip 7 and a substrate 3 . [0004] The image sensor chip 7 needs to be assembled in the confined space of the lens assembly seat 1. During the manufacturing process, glue is usually painted on the lens assembly seat 1 with a receiving cavity, and the filter 3 is pasted on the lens assembly seat 1. Assembling the lens assembly base 1 on the substrate 3, so tha...

AI Technical Summary

Problems solved by technology

[0006] To sum up, in the existing gas escape structure, after the gas escapes from the escape hole 5, it needs to be glued again to seal the hole and baked and solidified, which makes the production process complicated and reduces the production efficiency of the camera module.

[0007] In addition, during the transportation process of the semi-finished camera module without the air escape hole, the dust in the air can easily enter the camera module through the air escape hole 5 and fall on the image sensor chip 7, affecting the image quality of the camera module.
