Problems solved by technology

However, each lens will have a certain tolerance during manufacture, and the lens barrel 10' itself will also have a tolerance, and the degree of coincidence between the optical axis of the lens system and the optical axis of each lens is determined by the assembly status of each lens and lens barrel. The tolerance of the lens and the lens barrel will lead to a large deviation of the optical axis, especially when there are many lenses, the deviation of the optical axis of each lens will be superimposed to form a large deviation, which will affect the imaging quality of the lens module

Embodiment Construction

[0012] The lens module for a portable electronic device of the present invention is used for a small digital camera, or a portable electronic device such as a mobile phone and a PDA with a digital camera.

[0013] Please refer to figure 1 As shown, the lens module for the portable electronic device of the present invention includes a lens barrel 10 and a lens group 20 . The lens barrel 10 is a hollow cylindrical structure, and a hollow channel 102 is formed in the lens barrel 10 , and the hollow channel 102 is used for installing the lens group 20 . One end of the lens barrel 10 has an opening, and a transparent cover 30 is installed on the opening to protect the lens assembly 20 and prevent impurities such as dust from entering the lens barrel 10 and affecting the imaging quality.

[0014] The lens group 20 is made up of a plurality of lenses, the optical axis of the lens group 20 coincides with the central axis of the hollow passage 102, and the periphery of each lens has a...

Abstract

The invention is a lens module for a portable electronic device, comprising a lens cone formed with a hollow channel inside; a lens group held in the hollow channel, comprising plural lenses, the edge of each lens has plural mounting parts, each mounting part comprises a bump and a groove on two sides of the lens, and each lens is fastened with the adjacent lenses through the bump and groove so that all lenses are assembled together. The optical axis of the lens module is limited depending on the lens group itself instead of the lens cone, therefore reducing the optical axis deviation and improving the imaging quality.

Description

【Technical field】 [0001] The invention relates to a lens module for a portable electronic device, in particular to a lens module for a portable electronic device that reduces optical axis deviation. 【Background technique】 [0002] Digital cameras have become more and more popular, and people have higher and higher requirements for their image quality, and the optical axis deviation in the assembly process of the lens is one of the important factors affecting the image quality. [0003] Among existing lens modules for portable electronic devices, such as the lens system disclosed in U.S. Patent No. 4,199,220, its basic structure is shown in FIG. A plurality of lenses 201 ′, 202 ′ are embedded in the channel 102 ′ for converging optical signals passing through the lenses 201 ′, 202 ′. Wherein, the multiple lenses 201', 202' are directly installed in the lens barrel 10'. However, each lens will have a certain tolerance during manufacture, and the lens barrel 10' itself will a...
