Optical lens, camera module and assembling method thereof

Abstract

The present invention provides an optical lens. The optical lens comprises a first lens component comprising at least one first lens, a second lens component comprising at least one second lens, and afirst adhesive material, wherein the at least one second lens and the at least one first lens jointly form an imageable optical system, the first adhesive material is located in a first gap between the first lens component and the second lens component, the first adhesive material is suitable for supporting and fixing the first lens component and the second lens component after being cured, the first lens component is provided with a first bottom surface, the second lens component is provided with a second top surface, and the first bottom surface and / or the second top surface are / is providedwith a glue drawing area for arranging the first adhesive material, the first bottom surface is provided with a first adhesive blocking part, and / or the second top surface is provided with a third adhesive blocking part. The invention further provides a corresponding camera module and an assembling method of the optical lens. The optical lens is advantaged in that influence of the first adhesivematerial on the optical lens can be prevented, and the imaging quality of the optical lens or the camera module can be improved.

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 of the optical lens. Background technique [0002] With the popularization of mobile electronic devices, related technologies of camera modules used in mobile electronic devices to help users acquire images (such as video or images) have developed rapidly and improved rapidly, and in recent years, camera modules Groups have been widely used in many fields such as medical treatment, security, industrial production and so on. [0003] In the process of improving the imaging capability of the camera module, there are three main factors affecting the imaging quality: one is the imaging quality of the lens, and a high-quality lens can well correct the aberration of the optical system to achieve higher imaging quality; It is the light-sensing ability of the photosensitive chip. Generally speaking, t...

Problems solved by technology

[0005] However, when assembling the above-mentioned lenses, it is necessary to use adhesive materials to bond and fix the upper and lower sub-lenses. However, the adhesive materials are in a liquid state and have fluidity when they are not cured. There is a time interval between them, so the glue material has a tendency to flow and spread to both sides in the glue painting area. Aligned with a small gap, which allows the adhesive to be squeezed and spread both inside and outside the lens

The adhesive material diffused to the outside is to affect the appearance, and the second is to overflow and affect the motor or other components, thereby affecting the overall performance and reliability of the module; the adhesive material diffused to the inside is to flow into the lens and not expected to be bonded position, which affects the performance and reliability of the lens; the second is that it is easy to touch the adhesive material between the lens barrel of the sub-lens and the lens. The composition and performance of the two adhesive materials are different, which will affect the overall performance of the two adhesive materials. reliability
