Optical lens, camera module and assembly method thereof

Abstract

An optical lens includes a first lens component (100). The first lens component (100) includes one or more first lenses (101), a first lens barrel (102) and an adhesive (103). The inner side of the first lens barrel (102) is provided with a composite accommodating hole (600), at least one first lens (101) is embedded in the composite accommodating hole (600), and the composite accommodating hole (600) includes an annular accommodating area side wall ( 6011). The outer side of the embedded first lens (101) includes a first area (10131) and a second area (10132), and the first area (10131) and the second area (10132) are staggered. The first area (10131) is the area of ​​the outer side of the first lens (101) that is supported against the side wall (6011) of the accommodating area, and the second area (10132) is the area of ​​the outer side of the first lens (101) exposed on the side wall (6011). The area outside the side wall (6011) of the accommodating area. The adhesive glue (103) adheres the first lens barrel (102) to the first lens (101) by contacting the second area (10132). The optical lens, the corresponding camera module, and the assembling method of the optical lens and the camera module can reduce the lens position shift caused by the deformation of the lens barrel, and can improve the imaging quality of the optical lens or the camera module.

AI Technical Summary

Problems solved by technology

However, the actual trial production found that the imaging quality of the optical lens and camera module often deteriorates compared with the imaging quality obtained in the active calibration stage. This degradation sometimes exceeds the tolerance range, resulting in defective products

The applicant's research found that after the active calibration process was introduced into the assembly of the optical lens or camera module, the variation of the glue material, lens barrel or lens, and other unknown factors may be the cause of the above problems
