With reference to Fig. 2 and Fig. 3 of the Figure of description of the present invention, focusing for a preferred embodiment under this invention is taken the photograph
As module is elucidated with, wherein it is described focus camera module include a photo-sensitive cell 10, an optical lens 20 and
One microscope base 30, wherein the optical lens 20 is packaged in the top 302 of the microscope base 30, the microscope base
30 centers form light hole 301, and the optical lens 20 is maintained at the photosensitive of the photo-sensitive cell 10
Path 20.The light being reflected by the object is focused in camera module described in can entering from the optical lens 20
Portion, and photoelectric conversion is received and carries out by the photo-sensitive cell 10, to generate the image associated with object
(such as image or video).
It is noted that in camera module is focused described in the present invention, the type of the photo-sensitive cell 10
It is unrestricted with the type of the optical lens 20.Such as in an exemplary explanation, it is described photosensitive
Element 10 can be charge coupled cell (Charge Coupled Device, CCD), or described photosensitive
Element 10 can be metal oxide semiconductor device (Complementary Metal-Oxide
Semiconductor, CMOS), or the photo-sensitive cell 10 can be silicon photonics chip.Namely
Say, camera module is being focused described in the present invention, the photo-sensitive cell 10 refers to any to receive quilt
The optical element of photoelectric conversion is realized after the light of object reflection.Correspondingly, the optical lens 20 refers to appoint
The light what can allow for being reflected by the object focuses the outside of camera module described in and enters inside and improve the light
The optical element of line mass.
In camera module is focused described in the present invention, the optical lens 20 is directly encapsulated in the microscope base
30 top 302.That is, the described of the present invention focuses camera module and need not provide the mirror of prior art
Barrel structure, by such mode, it can reduce described focusing week of the camera module in the optical lens 20
The volume enclosed, with it is described focus camera module and be installed in an electronic equipment when, it is described to focus camera module energy
Enough spaces for taking the electronic equipment as few as possible, so that the electronic equipment can reserve more skies
Between for installing other components.In a specific example, around the optical lens 20
Any one direction can save at least 0.2mm space, that is to say, that the camera module that focuses
Head (i.e. described optical lens 20 and its surrounding) can save at least 0.4mm space, and this is for described
Focusing camera module, can be applied to intelligent, the lightening electronic equipment significant.
In addition, the camera module that focuses of the present invention need not provide the lens barrel structure of prior art, but will
The optical lens 20 is directly packaged in the microscope base 30, by such mode, can reduce raw material
Using to reduce the cost for focusing camera module, so as to improve the product competition for focusing camera module
Power.
During camera module is focused described in the encapsulation present invention, by a focus adjusting mechanism in the optical frames
The mode of optical lens 20 described in first 20 external stability, the optical lens 20 is adjusted relative to the sense
The position of optical element 10, to focus the image quality of camera module described in improvement.Therefore, in this course,
Even described focus adjusting mechanism causes the optical lens 20 to produce the pollutants such as solid particle, the solid particle
The inside for focusing camera module will not be also entered Deng pollutant, to prevent the pollutants such as the solid particle from making
Into dirty bad point, so that it is guaranteed that the image quality for focusing camera module.Produced in pollutants such as the solid particles
Afterwards, the pollutant such as the solid particle can at most be attached to the outer surface for focusing camera module, described fixed
After the completion of burnt camera module is packed, it can be removed by way of cleaning and focus camera module described in being attached to
The pollutants such as the solid particle of outer surface, described focus camera module to advantageously ensure that and be configured in the electricity
Image quality during the use of sub- equipment.
Further, such as Fig. 3, the camera module that focuses includes a cementing layer 40, wherein the cementing layer
40 between the optical lens 20 and the microscope base 30, for the optical lens 20 is directly sealed
Loaded on the microscope base 30, correspondingly the cementing layer 40 is annular in shape, by outside the ring-type of the optical lens 20
Edge is connected with the microscope base 30, and preferably it is formed by light-proof material.It is noted that institute
The optical lens 20 and the microscope base 30, and the cementing layer 40 can not only be connected by stating cementing layer 40
The junction that sealing results from the optical lens 20 and the microscope base 30 is can also be used to, so as to prevent this solid
Either environmental contaminants or extraneous light pass through the optical lens 20 and the microscope base to the pollutants such as body particle
30 junction focuses the inside that camera module is focused described in the outside entrance of camera module described in, with favourable
In the image quality that camera module is focused described in guarantee.
The cementing layer 40 forms the junction in the optical lens 20 and the microscope base 30.Specifically,
Optionally carried out a little at least one of relevant position of the optical lens 20 and the microscope base 30
Glue, after the completion of dispensing operation, the lower surface of the optical lens 20 is installed on the microscope base 30, so that
Glue is between the optical lens 20 and the microscope base 30, and the camera module that focuses is focused,
It can be carried out, adjusted by way of optical frames 20 described in the external stability in the optical lens 20 during focusing
After the completion of Jiao, make glue curing to form the glue between the optical lens 20 and the microscope base 30
