Description
Technical field
The present invention relates to a kind of camera lens module, particularly a kind of camera lens module with special construction spacing washer (Spacer).
Background technology
The camera lens module is an imaging system, and as the important component part of digital camera, it comprises assemblies such as eyeglass, lens barrel, holder.Most camera lens modules also comprise optical elements such as optical filter, to change the light condition of imaging system in shooting process, add high contrast, and then improve its shooting effect.In the camera lens module, usually need between each optical element, be provided with at interval, produce wearing and tearing to avoid adjacent optical elements because of phase mutual friction or collision, and then prevent that the optical property of optical element from worsening.
Disclose a kind of method at interval that between lens and optical filter, forms in the prior art, promptly in the assembling process of camera lens module, adopt the spacing washer of annular, it is arranged between the lens and optical filter in the lens barrel, make between described lens and the optical filter and keep at a certain distance away, with the minute surface that prevents lens contact with optical filter and produce the friction or the collision, thereby avoid optical elements such as lens, optical filter impaired.Generally, in the assembling process of camera lens module, need to utilize " some glue processing procedure ", its concise and to the point process is as follows: after eyeglass is put into lens barrel in regular turn, again spacing washer is put into camera lens, then on spacing washer, put UV glue, again that optical filter is placed on it and according to UV light, thus entire module is fixed.Yet, because factors such as the rheological of glue, coating method usually can cause eyeglass to come off inadequately because of glue, or influence image effect because of glue makes glue flow in the optics effective diameter too much.In addition, when utilizing Glue dripping head to put glue on spacing washer, can " striker " phenomenon take place because of the variation of spacing washer thickness.
In view of this, provide a kind of and " few glue " or " glue overflows " in the assembling process of camera lens module, can not occur, and prevent that Glue dripping head and spacing washer from the camera lens module of " striker " phenomenon taking place in fact for necessary.
Summary of the invention
Below will a kind of camera lens module be described with embodiment.
A kind of camera lens module, it comprises lens barrel, be contained in eyeglass and optical filter in this lens barrel, between this eyeglass and optical filter, be provided with spacing washer, this spacing washer comprises a first surface, one with this first surface opposing second surface and a side adjacent with this first surface, this first surface is mutually bonding with this optical filter, and this first surface is provided with first groove.
Compare with prior art, be provided with spacing washer between eyeglass in the described camera lens module and the optical filter, the mutually bonding face of spacing washer and optical filter is provided with first groove that can accommodate glue, thereby avoid in the assembling process of camera lens module, promptly putting in the glue process phenomenon that " few glue " or " glue overflows " occurs, can prevent that Glue dripping head and spacing washer from " striker " phenomenon taking place simultaneously.
