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, the center of microscope base 30 is formed with a light hole 301, wherein the optical lens 20 is direct
The top 302 of the microscope base 30 is packaged in, and the optical lens 20 is maintained at the photo-sensitive cell 10
Photosensitive path 20.The light being reflected by the object focuses shooting mould described in can entering from the optical lens 20
The inside of group, and photoelectric conversion is received and carries out by the photo-sensitive cell 10, it is associated with object to generate
Image (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.That is, the described of the present invention focuses camera module and need not provide the lens barrel structure of prior art, lead to
Cross such mode, can reduce it is described focus volume of the camera module around the optical lens 20,
With it is described focus camera module and be installed in an electronic equipment when, the camera module that focuses can lack as far as possible
Ground takes the space of the electronic equipment, so that the electronic equipment can reserve more spaces for installation
Other components.In a specific example, any one side around the optical lens 20
To at least 0.2mm space can be saved, that is to say, that head (the i.e. institute for focusing camera module
State optical lens 20 and its surrounding) at least 0.4mm space can be saved, this focuses shooting mould for described
It is significant that group can be applied to intelligent, the lightening electronic equipment.
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 top 302 of the microscope base 30, the convex of optical lens 20
For the microscope base 30, by such mode, the use that can reduce raw material is taken the photograph with reducing described focus
As the cost of module, so as to improve the product competitiveness for focusing camera module.That is, the optics
Camera lens 20 is substantially exposed in the outside of the microscope base 30, so as to the size of the camera end of the camera module.
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
