Optical lens, camera module and assembling method thereof

Abstract

The invention provides a camera module, which comprises a plurality of camera module components, wherein at least two camera module components are connected through a hot melt adhesive. The inventionfurther provides a corresponding assembling method of the camera module. The method comprises: bonding camera module components by using a hot melt adhesive to obtain a camera module; bonding the camera module components through the hot melt adhesive, which comprises the step that at least two camera module components which are separated from each other are bonded through the hot melt adhesive, orthe connection between the at least two camera module components is reinforced through a hot melt adhesive. According to the invention, the repair rate of the camera module can be improved by adopting the hot melt adhesive, the variation of the optical performance of the camera module caused by a baking process can be avoided or reduced, the external impact can be resisted through the bonding force and the toughness of the hot melt adhesive, and when the camera module is repaired or disassembled, pollution of adhesive material powder or particles to an optical element can be avoided or reduced.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular, the invention relates to an optical lens, a camera module and an assembly method thereof. Background technique [0002] With the development of terminals such as mobile phones and computers, users have greatly improved their various needs. Especially with the development of mobile phones, users' pursuit of shooting quality has led manufacturers to develop personalized and customized camera modules. , such as large aperture, large wide angle, lens with a large number of lenses to solve aberrations, etc. On the one hand, the optical design is becoming more and more complicated. On the other hand, the reality is that the complex optical system is very sensitive, which poses a big challenge to the manufacturing yield and product quality. Because the optical system of a large aperture and wide-angle camera module is more sensitive, the reliability of its manufacturing process a...

Problems solved by technology

However, such camera modules are often difficult to repair

In actual production, there will inevitably be a certain proportion of defective products

In the event of defective products, the above-mentioned modules based on thermosetting adhesive or UV hot-strand adhesive can only be scrapped entirely, which makes it difficult to reduce the cost of the camera module

In addition, thermosetting adhesives or UV hot-strand adhesives often need to be cured through a baking process. The applicant in this case found that the baking process may bring potential variations to the camera module, resulting in a decrease in the quality of the module.
