Abstract

Translated fromChinese

本发明提供一种镜头模组，该镜头模组包括镜座、与镜座配合的镜筒以及滤光片，该滤光片与镜筒或镜座是一体成型结构。所述镜头模组因其滤光片与镜筒或镜座是一体成型结构，使得该滤光片稳定固定在该镜筒或镜座上，避免了滤光片与间隔环之间的点胶工序，从而使镜头模组生产良率有所提高。

The invention provides a lens module. The lens module includes a lens base, a lens barrel matched with the lens base, and a filter. The filter is integrally formed with the lens barrel or the lens base. The lens module is integrally formed with the filter and the lens barrel or lens holder, so that the filter is stably fixed on the lens barrel or lens holder, avoiding glue dispensing between the filter and the spacer ring process, so that the production yield of the lens module has been improved.

Description

The camera lens module

Technical field

The present invention relates in particular to a kind of camera lens module with optical filter about a kind of camera lens module.

Background technology

Along with the development of optical image technology, the camera lens module is used widely in various imaging devices such as digital camera, video camera, and is integrated with the electronic installation such as mobile phone, notebook of camera lens module, more obtains numerous consumers' favor.Camera lens module with shoot function generally is made up of topmost eyeglass and mechanism's spare part.For at high-quality camera lens, be the assurance image quality, the position between each spare part should be fixed, so should adopt good assemble method assembles, come off to guarantee position relation firm relatively between each spare part, to be unlikely, thereby guarantee that camera lens has good image quality.

Please refer to Fig. 1, a kind of camera lens module 10 of prior art comprises lens barrel 11, some eyeglasses 12, optical filter 13 and spaced ring 14.Described eyeglass 12, optical filter 13 and spaced ring 14 all are contained in this lens barrel 11.Optical filter 13 is fixed together by gluing together with the mode of adhesive dispensing device point glue with spaced ring 14.

The optical filter 13 of this camera lens module 10 sticks on the spaced ring 14 in the mode of gummed; this method usually can apply inhomogeneous because of rotten, the viscose glue of viscose glue and because of the influence of 13 pairs of ultraviolet lights of optical filter make the viscose glue ultraviolet glue solidify not exclusively and optical filter 13 less with spaced ring 14 contacts area; be again different materials simultaneously; cause adhesion relatively poor and cause optical filter 13 to come off, thereby camera lens module 10 was lost efficacy from spaced ring 14.It is on the low side that Jiao He mode can cause camera lens module 10 production yields in addition.

Summary of the invention

Mirror is arranged at this, be necessary to provide a kind of and can make the camera lens module that optical filter is stably fixed on camera lens or the microscope base and the production yield increases.

A kind of camera lens module comprises microscope base, the lens barrel that cooperates with microscope base and optical filter, and this optical filter and lens barrel or microscope base are integrated formed structures.

Compared to prior art, described camera lens module is an integrated formed structure because of its optical filter and lens barrel or microscope base, make this optical filter be stably fixed on this lens barrel or the microscope base, be unlikely to come off from this lens barrel or microscope base, avoided the some glue process between optical filter and the spaced ring, increased thereby make the camera lens module produce yield.

Embodiment

Below with reference to accompanying drawing the present invention is described in further detail.

See also Fig. 2, the camera lens module 100 in the first embodiment of the invention comprises microscope base 110, the lens barrel 120 that cooperates with this microscope base 110 and is housed in optical filter 130 and lens set 140 in this lens barrel 120 that this optical filter 130 is one-body molded with lens barrel 120.Described cooperation is fixedly connected or is threaded, and in the present embodiment, is threaded.

Optical filter 130 and lens barrel 120 are can in-molded technology (Insert Molding) one-body molded, see also Fig. 3, and this integral formation method mainly may further comprise the steps:

Optical filter 130 is put into injection mold, then matched moulds;

The jet-out plastic material to this injection mold, injection mo(u)lding lens barrel 120;

Product is taken out in die sinking, obtains integrated optical filter 130 and lens barrel 120.

See also Fig. 4, the lens barrel 220 that the camera lens module 200 in the second embodiment of the invention comprises microscope base 210, cooperate with this microscope base 210 and optical filter 230 and the lens set 240 that is housed in this lens barrel 220, this optical filter 230 is one-body molded with microscope base 210.Described cooperation is fixedly connected or is threaded, and in the present embodiment, is threaded.

Optical filter 230 is one-body molded with in-molded technology with microscope base 210, sees also Fig. 5, and this integral formation method mainly may further comprise the steps:

Optical filter 230 is put into injection mold, then matched moulds;

The jet-out plastic material to this injection mold, injection mo(u)lding microscope base 210;

Product is taken out in die sinking, obtains integrated optical filter 230 and microscope base 210.

Compared to prior art, described camera lens module is an integrated formed structure because of its optical filter and lens barrel or microscope base, make this optical filter be stably fixed on this lens barrel or the microscope base, be unlikely to come off from this lens barrel or microscope base, avoided the some glue process between optical filter and the spaced ring, thereby the production yield of camera lens module increased.

In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention all should be included in the present invention's scope required for protection.
