AI Technical Summary

Problems solved by technology

During the screw locking process, the screws will exert mechanical force on the printed circuit board, resulting in deformation of the printed circuit board. At the same time, the locking force of different screws is different, resulting in uneven mechanical stress on the printed circuit board and tilting. The sensor on the printed circuit board is also tilted and cannot be kept perpendicular to the optical axis of the lens, which affects image quality

Abstract

The invention discloses a lens module, a camera module and an assembly method. The lens module comprises a lens, a locking sheet and a clamping ring, wherein the lens comprises a head and a body, which are axially connected, and the radius of the head is larger than the radius of the body; the locking sheet is sleeved at the outside of the body of the lens, and at least one locking hole for locking with a whole terminal is formed; and the clamping ring is screwed and fixed at the outside of the body of the lens and clamps and fixes the locking sheet with the head of the lens together. The lensmodule replaces the existing printed circuit board locking by an indirect locking mode of the lens and the whole terminal, so that a relative angle between a sensor and the lens of the camera moduleis not affected.

Description

technical field [0001] The invention relates to the field of photography, in particular to a lens module, a camera module and an assembly method. Background technique [0002] At present, when installing a large-sized camera module with a printed circuit board with a length and width of more than 38mmX38mm on the market, 3-4 locking holes are generally opened on the printed circuit board when it is installed in the terminal machine, and then the screw The camera module is fixed on the terminal machine by locking to improve stability. During the screw locking process, the screws will exert mechanical force on the printed circuit board, resulting in deformation of the printed circuit board. At the same time, the locking force of different screws is different, resulting in uneven mechanical stress on the printed circuit board and tilting. The sensor on the printed circuit board is also inclined and cannot be kept perpendicular to the optical axis of the lens, which affects the...
