Abstract

The present invention discloses a camera module group lens, a camera module group, an assembly method of a camera module group lens and an assembly method of a camera module group. The camera module group lens comprises at least one internal optics lens, at least one external optics lens and a lens-barrel part. Each internal optics lens is arranged in the space of the lens-barrel part according to a predetermined order, each external optics lens is arranged out of the lens-barrel part in the height direction of the lens-barrel part, and each internal optics lens and each external optics lens are both located on the optical path of the camera module group lens. The design mode is configured to shorten the assembly tolerance chain of a lens and reduce the distance from the lens to a chip, so that the back focal length of a small lens may be realized and the higher imaging quality may be ensured.

Description

technical field [0001] The invention relates to the field of camera modules, in particular to a lens of a camera module, a camera module and an assembly method thereof. Background technique [0002] With the gradual expansion of the application field of camera modules, the demand for camera modules from all walks of life continues to increase, and the quality requirements for camera modules are also getting higher and higher, which puts higher demands on the camera module manufacturing industry. Requirements, so that the camera module can obtain higher image quality at a lower cost. [0003] In the conventional camera module assembly process, the lens is an independently assembled part, which includes a lens barrel (including a diaphragm), a lens, a spacer, a stopper, and other structures. The assembly process includes: placing the spacer with the The lenses are loaded into the lens barrel in order, and the last lens is fixed with glue or a pressure ring to complete the ass...
