Abstract
The utility model discloses a focusing-free optical camera module, which comprises a camera lens and an image chip. The lens is directly glued onto the image chip via glue water, the camera lens consists of a protecting spacer ring, a distance spacer ring and a lens group comprising a first lens and a second lens, the distance spacer ring is fixedly arranged between the first lens and the second lens, the protecting spacer ring is fixedly arranged on the surface of the first lens, the second lens is glued on the image chip via glue water, and a surface, which is opposite to the image chip, of the second lens is a plane. The surface, which faces to the image chip, of the second lens is the flat-plate glass plane which can be directly glued with protecting glass of the image chip, so that the aperture of the focusing-free lens group is reduced, product cost of the focusing-free camera lens is greatly lowered, the focusing-free lens group and the protecting glass of the image chip are tightly glued via shadow less glue with high light transmittance rate, so that the total focusing-free optical camera module is glued more firmly, and reliability of products is optimized.
Description
Technical field
The utility model relates to optics camera field, especially a kind of optics camera module of exempting to focus.
Background technology
In being the patent of 201654308U, notification number recorded and narrated a kind of optics camera module of exempting to focus; Jiao behind the machinery is foreshortened in 100 microns; save spacer ring camera lens directly is glued on the cover glass of image chip with glue, reduce the method that manufacturing tolerance is made the high-quality optics camera module of exempting to focus with this.
In this patent documentation; last surface of exempting from the focusing lens group is optical aspherical surface; can not be directly and the cover glass of image chip directly bonding; and need beyond the optics effective diameter, establish segment structure zone in addition as the position bonding with the image chip cover glass; so just increased the bore of exempting from focusing lens; what make that a slice glass wafer (diameter 200mm) go up to obtain exempts from focusing lens product decreased number; thereby lifting exempt from the cost of products of focusing lens; and for the whole optics camera module of exempting to focus; exempt from focusing lens and image chip when bonding; have only the neighboring area bonding; and the centre is still separation; it is not very abundant causing bonded areas, and product reliability can not optimization.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of optics camera module of exempting to focus, and can reduce the bore of exempting from the focusing lens group, and makes the whole optics camera module of exempting to focus bond more firmly.
The utility model for the technical scheme that solves its technical matters and adopt is: a kind of optics camera module of exempting to focus, comprise camera lens and image chip, this camera lens directly sticks on the image chip by glue, and described camera lens is by the protection spacer ring, constitute jointly apart from spacer ring and the lens set be made up of first and second eyeglass; This is fixedly arranged between first and second eyeglass apart from spacer ring, and the protection spacer ring is fixedly arranged on first lens surface, and described second eyeglass sticks on the image chip by glue, and this second eyeglass is the plane over against the surface of image chip.
As further improvement of the utility model, the surface of described image chip is provided with cover glass, and this described second eyeglass directly is bonded to mutual applying over against the surface of image chip and with the surface of described cover glass by glue; Described glue is no shadow glue, is UV glue.
As further improvement of the utility model, described camera lens second eyeglass over against the spacing between the surface of the surface of image chip and described cover glass less than 10 μ m.
The beneficial effects of the utility model are: the utility model is the sheet glass plane with second eyeglass towards the surface design of image chip; can be directly and the cover glass of image chip bonding; thereby reduced the bore of exempting from the focusing lens group; can go up obtain to have more at a slice glass wafer (diameter 200mm) and exempt from focusing lens product number about 80% than original technology; greatly reduce the cost of products of exempting from focusing lens; and exempt between focusing lens group and the image chip cover glass be in the middle of or periphery all is a no shadow glue close adhesion with high light transmission rate; increased adhesion area; make the whole optics camera module of exempting to focus bond more firmly, reliability of products has obtained optimization.

Fig. 2 is the light path synoptic diagram of camera lens described in the utility model.
Embodiment
Embodiment to the optics camera module of exempting to focus of the present utility model is elaborated with reference to the accompanying drawings.
A kind of optics camera module of exempting to focus; comprise camera lens and image chip 4; this camera lens directly sticks on the image chip 4 by glue; described camera lens is by protection spacer ring 1, constitute jointly apart from spacer ring 3 and the lens set 2 be made up of first eyeglass 21, second eyeglass 22; this is fixedly arranged between first eyeglass 21, second eyeglass 22 apart from spacer ring 3; protection spacer ring 1 is fixedly arranged on first eyeglass, 21 surfaces; described second eyeglass 22 sticks on the image chip 4 by glue, and this second eyeglass 22 is the plane over against the surface of image chip 4.
In the present embodiment, the surface of described image chip 4 is provided with cover glass 5, and this second eyeglass 22 directly is bonded to mutual applying over against the surface of image chip 4 and with the surface of described cover glass 5 by glue, and described glue is no shadow glue, is UV glue.
Described camera lens second eyeglass 22 over against the surface of image chip 4 and and the surface of described cover glass 5 between spacing less than 10 μ m.
