Abstract

The present application provides a production management method of an optical lens, and the method comprises the steps: preparing a first lens member and a second lens member separated from each other, and forming an identification pattern recording production information on at least one of the first lens member and the second lens member; pre-positioning the first lens member and the second lensmember; adjusting and determining a relative position of the first and second lens members based on the active calibration; bonding the first and second lens members; recording assembly information ofthe first lens member and the second lens member, and correspondingly mapping the assembly information to the identification pattern; and identifying the identification pattern to obtain related information of the suspected fault lens. The invention further provides a corresponding optical lens, a camera module and a production management system of the camera module. According to the invention, the related information of the suspected faulty lens component can be conveniently and quickly obtained, the cause of poor process can be found in time, the lens manufacturing process can be improved,and the economic loss can be reduced.

Description

technical field [0001] The present application relates to the field of optical imaging technology, in particular, the present application relates to an optical lens, a camera module and a production management method thereof. Background technique [0002] With the popularization of mobile electronic devices, the relevant technologies of camera modules used in mobile electronic devices to acquire images (such as video or images) are becoming more and more mature, and in recent years, camera modules are used in medical, security, industrial production, etc. It has been widely used in many fields. [0003] At present, the market has put forward higher and higher requirements for the imaging quality of camera modules. Generally, there are three main factors that affect the imaging quality of the camera module: 1) the ability of the photosensitive chip to receive light; 2) the image processing algorithm, the processing algorithm used by different manufacturers is different, even...
