Description

Optical lens, camera module and assembly method thereof

technical field

The present invention relates to the technical field of optical imaging, and in particular, the present invention relates to an optical lens, a camera module and an assembly method of the optical lens.

Background technique

With the popularization of mobile electronic devices, the related technologies of camera modules used in mobile electronic devices to help users obtain images (such as videos or images) have been rapidly developed and advanced, and in recent years, camera modules The group has been widely used in many fields such as medical treatment, security, industrial production and so on.

In the process of improving the imaging capability of the camera module, there are three main factors that affect the imaging quality: first, the imaging quality of the lens, a high-quality lens can well correct the optical system aberrations and achieve higher imaging quality; It is the photosensitive ability of the photosensitive chip. Generally speaking, the larger the single pixel area of the photosensitive chip, the stronger the photosensitive ability. The third is ISP, that is, the image processing algorithm. Different manufacturers have different algorithm capabilities and different image optimization capabilities. For hardware of the same specification, the final images obtained after processing by different manufacturers will also be quite different. Among the above factors, the quality of the lens determines the imaging capability of the entire camera module. In order to obtain high-quality large-aperture lenses, wide-angle lenses, telephoto lenses, and higher-quality imaging, the lenses designed by manufacturers include The number of lenses is increasing, reaching six, seven or even more. The increase in the number of lenses requires very high precision for lens assembly. However, due to the existence of assembly tolerances and component tolerances, the more the number of lenses, the greater the tolerance of the final lens molding, which affects its imaging quality. At the same time, the sensitivity of large aperture and large wide-angle lenses It is also higher, and requires higher accuracy of lens assembly. All in all, due to the existence of component tolerances and assembly tolerances, the imaging quality and yield of the lens are greatly affected.

In order to overcome the above difficulties, the present invention provides a multi-group lens, which can adjust the imaging quality of the lens through active calibration. When the component tolerance and assembly tolerance are within a certain range, the imaging quality of the lens can be compensated through active calibration. , and then assemble and fix multiple groups through adhesive bonding to form a lens with a perfect optical system.

However, when assembling the above-mentioned lens, it is necessary to use adhesive material to bond and fix the upper and lower sub-lenses. However, the adhesive material is in a liquid state and has fluidity when it is 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 painting glue area. At the same time, when the glue material is set in the painting glue area, the glue material is generally an elliptical ring in cross section, and the upper and lower sub-lenses are automatically After calibration, there is a small gap, which allows the glue to be squeezed and spread to the inside and outside of the lens. The adhesive material diffused to the outside affects the appearance first, and the overflow affects the motor or other components, thereby affecting the overall performance and reliability of the module; the adhesive material diffused to the inside is the unwanted adhesive that flows into the lens. position, thus affecting the performance and reliability of the lens; the second is the adhesive material that is easily contacted between the lens barrel and the lens of the sub-lens. The composition and performance of the two adhesive materials are different, which will affect the overall performance of the two adhesive materials. reliability.
