Abstract

The invention provides an assembling method of an optical lens. The assembling method of the optical lens comprises the following steps of preparing a first lens component and a second lens componentwhich are mutually separated; pre-positioning the first lens component and the second lens component; regulating and determining the relative positions of the first lens component and the second lenscomponent on the basis of active calibration; and bonding the first lens component and the second lens component, so that the first lens component and the second lens component are fixed and maintainin the relative positions determined for active calibration, wherein a first lens has a mark, and the mark can be shown in an image using an optical axis calibration lens as a shot object; and in thepre-positioning step, the optical axis calibration lens is shot, the position of a first optical axis is recognized according to the mark shown in the shot image, and the pre-positioning is performedaccording to the recognized position of the first optical axis and the second lens component. The invention also provides an assembling method of a camera module, the corresponding optical lens and the corresponding camera module. The lens is enabled to have a stable feeding position during the pre-positioning; the production efficiency can be improved; and the product qualification rate is 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 thereof. 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 order to meet more and more extensive market demands, high pixel, small size, and large aperture are irreversible development trends of existing camera modules. However, it is very difficult to achieve the three requirements of high pixel, small size and large aperture in the same camera module. For example, the compact development of mobile phones and the increase in the ...
