Abstract
The utility model discloses a focusing-free optical camera module group which includes a shot, an image chip, and a lens outer cover. Lenses are adhesively connected via adhesive layers to form the shot. The last surface of the shot is flat and is completely glued on the image chip. Because the lenses are directly glued together via the adhesive layers to form the shot, a gasket is saved, and the height of the module group is reduced on the premise that the high pixel is guaranteed. A structural area which is additionally arranged so as to assemble conventional lenses with the gasket is canceled, so the lens size is reduced, and the number of focusing-free shot products arranged on a glass wafer can reach to maximum, and consequently the cost of the focusing-free shot product is reduced. The last surface of the shot is a flat glass which is glued together with a protection glass of the image chip by a high light transmissivity UV glue which is just a few micrometers thick, so a conventional spacer or pedestal is saved, the spacer thickness tolerance generated in spacer production is eliminated, and consequently the focusing-free effect is achieved, and the excellent image quality of the focusing-free camera module group is guaranteed.
Description
Technical field
The utility model belongs to optics camera field, is specifically related to a kind of ultrathin type optics camera of exempting to focus.
Background technology
Progressively to new material, high pixel, microminiaturized development, this just orders about traditional design needs further to improve in the development of camera module.
Conventional lenses needs between a plurality of eyeglasses to connect through packing ring when assembling, and eyeglass is in order to establish segment structure zone with the packing ring assembling in addition; So just strengthened lens dimension; And then strengthen the module size, not only expend starting material, and be unfavorable for that product is to lightening development.
Jiao foreshortens in 100 microns after in patent documentation 1 (the open 201654308U patent gazette of China), having recorded and narrated machinery; Save spacer ring and directly be glued to camera lens on the cover glass of image chip, reduce the method that manufacturing tolerance is made the high-quality optics camera module of exempting to focus with this with glue.But in patent documentation 1, last surface of exempting from the focusing lens group is for optical aspherical surface, can not be directly and the cover glass of image chip directly bonding; Be used as the position bonding and need beyond the optics effective diameter, establish a segment structure zone in addition 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, thus 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 middle be still separation; It is not very abundant causing bonded areas, and product reliability can not optimization.
The utility model content
In order to overcome above-mentioned defective, the utility model provides a kind of optics camera module of exempting to focus, and this optics camera module of exempting to focus can reduce the volume of module, promotes utilization rate of raw materials, and the whole optics camera module of exempting to focus bonds 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 comprises camera lens, image chip and camera lens outer cover, and said camera lens is made up of some eyeglass assemblings, is provided with adhesive coating between the adjacent mirror, and said adhesive coating bonding is positioned at the eyeglass of its both sides.Said adhesive coating is light-cured resin cementing agent (a UV glue).Because all eyeglasses, have saved the packing ring that conventional lenses is used directly through the adhesive coating formation camera lens that fits together when assembling, guaranteeing to reduce the module height under the high pixel prerequisite; And cancel the segment structure zone that conventional lenses is established for the assembling with packing ring in addition, and reduce lens dimension, make a slice glass wafer (diameter 200mm) go up the focusing lens product number of exempting from that obtains and reach at most, reduced the cost of products of exempting from focusing lens.
The utility model for the further technical scheme that solves its technical matters and adopt is:
