Self-positioning self-shading type lens

Abstract

The invention provides a self-positioning self-shading type lens. The self-positioning self-shading type lens comprises an integrally molded optical part, an upper connection area, a joint part and a lower connection area, wherein the optical part is arranged in the upper connection area which is connected with the lower connection area via the joint part, the upper connection area comprises a top face, an outer face and an inner face, the lower connection area comprises a bottom face, an outer face and an inner face, the joint part comprises a top face and a bottom face, the bottom face of the joint part of one self-positioning self-shading type lens is in butt joint with the top face of the upper connection area of another self-positioning self-shading type lens, and the inner face of the lower connection area of one self-positioning self-shading type lens is in butt joint with the outer face of the upper connection area of another self-positioning self-shading type lens. Assembling of the self-positioning self-shading type lens is simple to operate, and free of assembly error between a lens and a lens cone and operational problem in positioning. The lens is directly positioned, light is shaded directly, and production requirements for high efficiency and quality are met.

Description

technical field [0001] The invention relates to a lens, in particular to a lens with simple positioning and self-shading. Background technique [0002] With the multi-functional development of electronic products, lens modules are widely used in consumer electronic products such as mobile phones, notebook computers, digital cameras, and personal digital assistants. While pursuing multi-functionality, people also hope that electronic products have excellent image effects, that is, lens modules are required to have high-quality imaging. [0003] A lens module in the prior art includes a lens barrel 221 , and a first lens 222 , a spacer ring 223 , a second lens 224 and the like disposed in the lens barrel 221 . A plurality of optical elements in the lens module are usually installed along the axis of the lens barrel 221 to achieve designed optical performance and predetermined imaging quality. During assembly, several optical elements are usually installed in the lens barrel ...

AI Technical Summary

Problems solved by technology

Since the outer diameter of the lens 222 is equivalent to the inner diameter of the lens barrel, and the side of the lens 222 is closely matched with the inner wall of the lens barrel 221, during assembly, the whole process of the lens 222 being loaded into the bottom of the lens barrel from the top of the lens barrel is difficult to assemble due to friction. Difficult, and due to friction, the lens 222 is prone to distortion, thereby affecting the assembly efficiency and imaging quality of the entire lens module, causing the lens module to become a defective product

This not only reduces the assembly yield of the lens module, but also greatly increases the manufacturing cost of the lens module

[0004] In addition, it is necessary to add a spacer ring 223 to adjust the distance between the two lenses, which increases materials and processes and increases production costs
