Description
Technical field
The present invention is about a kind of camera lens module package technique, especially about a kind of camera lens module and spaced ring thereof of digital camera.
Background technology
Along with Development of Multimedia Technology, digital camera, video camera are more and more favored by consumers in general, when people's logarithmic code camera, video camera are pursued miniaturization, wish to have good shoot function again.Camera lens module with shoot function generally is made up of topmost eyeglass and mechanism's spare part.For a high-quality camera lens, in order to guarantee the image quality of digital camera, position between each spare part should be fixed, so should adopt a good assemble method assembles, so that each part of assembling back is firm, unlikely coming off, thus the camera lens after guaranteeing to assemble has favorable imaging quality.
Existing a kind of camera lens module comprises a lens barrel, a plurality of eyeglasses, a plurality of spaced rings and an optical filter.Described eyeglass, spaced ring and optical filter all are contained in this lens barrel.Described spaced ring is one circular, and the centre has a hole, is used to allow incident light penetrate.Optical filter and spaced ring are fixed together by gluing together with the mode of adhesive dispensing device point glue.
The optical filter of this camera lens module is pasted between the camera lens on the spacer ring in the mode of gummed; this method usually can be spared because of rotten, the viscose glue crawling of viscose glue; and not exclusively cause optical filter to come off, thereby make the inefficacy of camera lens module from spaced ring because of optical filter solidifies viscose glue to the influence of ultraviolet light.
Summary of the invention
In view of this, be necessary to provide a kind of camera lens module and spaced ring thereof that can make the optical element fixing-stable.
A kind of spaced ring comprises a cylindrical shell and a ring bodies that is fixed on this cylindrical shell xsect.Described cylindrical shell madial wall is provided with a fixed sturcture, is used for cooperating fixing optical element in this cylindrical shell with described ring bodies.Described ring axis and this tubular axis are point-blank.
A kind of camera lens module comprises lens barrel, optical element and an above-mentioned spaced ring that is placed in the lens barrel.
This camera lens module is made up of a cylindrical shell and a ring bodies because of its spaced ring, makes to treat that assembling optical element stably is fixed in this spaced ring, thereby the product yield is risen.

Embodiment
For the present invention being done further explanation, lift a preferred embodiment and conjunction with figs. and be described in detail as follows.
See also Fig. 1 and Fig. 2, the camera lens module in the embodiment of the invention comprises optical element and spaced rings 13 such as a lens barrel 10, lens set 11, an optical filter 12.Described lens set 11, spaced ring 12 and optical filter 12 all are contained in the lens barrel 10.
This lens set 11 comprises at least one eyeglass 111 and at least one iris diaphragm plate 112, is used for imaging.Present embodiment adopts two eyeglasses 111, and the centre is separated by an iris diaphragm plate 112.
Described optical filter 12 can be a square, is used to eliminate the colour cast that causes because of infrared ray.
Described spaced ring 13 comprises a cylindrical shell 131 and a ring bodies 132, this ring bodies 132 is fixed on described cylindrical shell 131 xsects, and the axis of the axis of ring bodies 132 and cylindrical shell 131 point-blank, for example, this ring bodies 132 can in be connected to the end or the middle part of described cylindrical shell 131, the internal diameter of the diameter of this ring bodies 132 and described cylindrical shell 131 is suitable at this moment, also can be external in the cross-sectional end of this cylindrical shell 131, in addition, ring bodies 132 also can further extend outside cylindrical shell 131 sidewalls, and this moment, the diameter of ring bodies 132 can be more than or equal to the external diameter of cylindrical shell 131.Present embodiment adopts the cross-sectional end that is connected to described cylindrical shell 131 in the ring bodies 132.This spaced ring 13 is used for ccontaining described optical filter 12, and places on the described ring bodies 132.
The sidewall of this cylindrical shell 131 is provided with a perforate 133 near ring bodies 132 1 sides, utilizes this perforate 133 can insert optical filter 12 to cylindrical shell 131.The internal diameter of the external diameter of this cylindrical shell 131 and lens barrel 10 is suitable, so that fix this spaced ring 13.
The madial wall of this cylindrical shell 131 is provided with fixed sturcture, this fixed sturcture can be for being provided with two pickup grooves 134,135 with respect to perforate 13, also can be a fastener integrally formed with cylindrical shell 131, this fastener can be a projection that is extended by the cylindrical shell inboard, is used for cooperating with ring bodies 13 fixedly optical filter 12 in cylindrical shell 131.Present embodiment adopts the form that two pickup grooves 134,135 are set on the madial wall of cylindrical shell 131.
This pickup groove 134,135 can be set according to the profile of optical element, and quantity also can be arranged to one or more as required.
This ring bodies 132 is provided with a center pit 136, is used to allow incident light inject, and the edge towards the thing side of this center pit 136 is arranged to inclined-plane 137, and this inclined-plane 137 can be a wedge shape inclined-plane.
The angle on the diameter of the thickness of this ring bodies 132, center pit 136 and inclined-plane 137 designs according to the different optical designing requirement.
Seeing also Fig. 1 and Fig. 3, is example with above-mentioned camera lens module embodiment, and number of assembling steps is as follows:
The first step: described lens barrel 10 is provided;
Second step: described lens set 11 is provided, and by the optical design requirement, assembly lens 111 and iris diaphragm plate 112 are in lens barrel 10 in regular turn.
The 3rd step: a described optical filter 12 and spaced ring 13 is provided, optical filter 12 inserted from perforate 133, and allow any two adjacent angular of optical filter 12 match fixing with pickup groove 134,135.Be understandable that this optical filter 12 can be directly inserted in the tube from the opening of the cylindrical shell 131 of spaced ring 13.
The 4th step: for the further fixing position of optical filter 12 and spaced ring 13, be unlikely loosening or come off, in the gap 14 of optical filter 12 and cylindrical shell 131 formation of spaced ring 13, insert high coefficient of viscosity glue 15.
The 5th step: utilize this high coefficient of viscosity glue 15 of ultraviolet light polymerization.Because this moment, glue was not covered by optical filter 12 and his thing, so be easy to be cured fully.
The 6th step: the above-mentioned spaced ring 13 that optical filter 12 is housed is assembled in the lens barrel 10.
So, just, finished the assembling of camera lens module.
In the 6th step, can utilize the outside dimension of spaced ring 13 and the internal diameter of lens barrel 10 to carry out fixed intervals ring 13 in the mode that closely cooperates or interfere, also can fix this spaced ring 13 in the mode that a glue glued adhesion is carried out in the spaced ring 13 and the gap of lens barrel 10 formation, guarantee that spaced ring 13 does not come off, and, in the spaced ring 13 except that can ccontaining optical filter 12, can also ccontaining other optical elements, as eyeglass 111 is placed in the spaced ring 13.
In addition, those skilled in the art also can do other variation in spirit of the present invention, as long as it does not depart from technique effect of the present invention, all should be included within the present invention's scope required for protection.
