Specific embodiment
It is described below for disclosing the present invention so that those skilled in the art can be realized the present invention.It is excellent in being described below Embodiment is selected to be only used as illustrating, it may occur to persons skilled in the art that other obvious modifications.It defines in the following description Basic principle of the invention can be applied to other embodiments, deformation scheme, improvement project, equivalent program and do not carry on the back Other technologies scheme from the spirit and scope of the present invention.
With reference to Fig. 1 and Fig. 2, the first specific embodiment of camera module group lens provided by the invention will be set forth.Such as Shown in Fig. 1 and Fig. 2, a camera module group lens 10, including an at least internal optics eyeglass 11,12 and of an at least external optical eyeglass One lens barrel unit 13, wherein each internal optics eyeglass 11 be arranged at along the short transverse of the lens barrel unit 13 it is described The inner space of lens barrel unit 13, each external optical eyeglass 12 are arranged at institute along the short transverse of the lens barrel unit State the outside of lens barrel unit 13, for example, the lens barrel unit 13 top or bottom exterior space, with the internal optics mirror Piece 11 is located on the same optical path of the camera module group lens 10, but the external optical eyeglass 12 be not included in it is described The inside of lens barrel unit 13.
This preferred embodiment includes internal optics eyeglass 11 described in three pieces, embedding each other between each internal optics eyeglass 11 It closes, is fixed in the accommodating chamber 131 that the lens barrel unit 13 has after chimeric, wherein the adjacent internal optics eyeglass 11 Between can be used spacer ring carry out between connection, the edge of each internal optics eyeglass 11 can also be handled, Such as gluing, so that each internal optics eyeglass 11 is directly entrenched in order through the bonding of the glue of coating each other Together, the structural members such as spacer ring are saved.A Lens assembly is formed after each internal optics eyeglass 11 is entrenched togather, then will Each internal optics eyeglass 11 is installed on the inside of the lens barrel unit 13 as a whole, and is fixed, this feelings The group between machining accuracy and each internal optics eyeglass 11 and the lens barrel unit 13 under condition, to the lens barrel unit 13 It is lower to fill required precision, advantageously reduces manufacturing cost, and reduce assembling procedure, reduces assembling tolerance chain, saves assembling Time improves production efficiency and product yield.
In the preferred embodiment, it is embodied as a piece of external optical eyeglass 12, the external optical eyeglass 12 is installed In the bottom of the lens barrel unit 13, wherein the edge of the external optical eyeglass 12 is connected with the bottom of the lens barrel unit 13 It connects.Implementable is to apply daub in the top surface edge of the external optical eyeglass 12 and the bottom surface of the lens barrel unit 13 The two is secured together by water, so that the external optical eyeglass 12 is corresponding with each internal optics eyeglass 11, is respectively positioned on On the optical path of the camera module group lens 10.
Since the lens barrel unit 13 is traditional black objective tube, there is light-blocking function, ambient can be prevented from non- Place except light beam incidence channel enters inside the camera module group lens 10, and can prevent from entering from light beam incidence channel Light leakage inside the camera module group lens 10 is gone out, and the external optical eyeglass 12 is not set to the lens barrel portion Inside part 13, so a light blocking layer 121 is arranged in the outside of the external optical eyeglass 12 in the present invention, wherein the light blocking layer 121 must be completely covered the entire side of the external optical eyeglass 12, to prevent 10 light leakage of camera module group lens, and prevent Only external stray light enters inside the camera module group lens 10, to guarantee the image quality of the camera module group lens 10.
In other embodiments of the invention, for the camera module group lens 10, in the camera module group lens In 10, the outside of the external optical eyeglass 12 can include without the light blocking layer 121, i.e., the described camera module group lens 10 It is the external optical eyeglass 12 of not set light blocking layer, since the light blocking layer 121 can be configured in subsequent handling, Therefore, the light blocking layer 121 for the camera module group lens 121 it is not necessary to.
After the camera module group lens 10 are installed in corresponding camera module, in order to guarantee the camera module The light blocking layer 121 is arranged to the external optical eyeglass 12 being assembled in camera module in image quality, can also be When assembling camera module, the light blocking layer is set in the outside of the external optical eyeglass 12 of the camera module group lens 10 121, then the camera module group lens 10 for being set the light blocking layer 121 and photosensitive device are assembled into camera module.
In short, the camera module group lens 10 both may include the light blocking layer 121, it can not also include the light blocking layer 121。
When the camera module group lens 10 include the light blocking layer 121, the setting time of the light blocking layer 121 can be adopted With following three kinds of modes: (1) in advance in the outside of the external optical eyeglass 12 light blocking layer 121 be set, it then will be described External optical eyeglass 12 is assembled in the camera module group lens 10；(2) the external optical eyeglass 12 is assembled in the camera shooting After module group lens 10, then it is arranged described when photosphere 121；(3) by the camera module mirror including the not set light blocking layer 121 After first 10 are assembled into camera module with photosensitive device, the light blocking layer 121 is set in the outside of the external optical eyeglass 12.
Preferably, the light blocking layer 121 is set by being coated with black glue in the outside of the external optical eyeglass 12, it is described Black glue is chosen as hot-setting adhesive, and the light blocking layer 121 is formed after solidification.
With reference to Fig. 3, the camera module including camera module group lens 10 described above will be set forth.As shown in figure 3, one takes the photograph As mould group, including the camera module group lens 10 and a photosensitive device 20, the photosensitive device 20 includes a sensitive chip 21, institute Camera module group lens 10 are stated to be arranged on the photosensitive path of the sensitive chip 21, when object reflection light pass through described in take the photograph After entering the camera module inside as module group lens 10, photoelectric conversion is received and carries out by the sensitive chip 21, thus In subsequent process, the camera module can obtain image relevant to object.
The photosensitive device further comprises an optical filter 22, a wiring board 23 and a microscope base 24, wherein the optical filter 22 are installed on the inside of the microscope base 24, and are arranged at the top of the sensitive chip 21, wherein the sensitive chip 21 pastes Top loaded on the wiring board 23, the wiring board 23 are installed on the bottom of the microscope base 24 and make the sensitive chip 21 In the cavity of the inside of the microscope base 24, and a spacing, the two are kept between the sensitive chip 21 and the microscope base 24 And be not directly contacted with, i.e., the described photosensitive device 20 is made of COB (chip on board) technique.
The external optical eyeglass 12 is arranged between the lens barrel unit 13 and the microscope base 24, i.e., the described exterior light The top surface edge for learning eyeglass 12 is connected to the bottom surface of the lens barrel unit 13, the bottom of the external optical eyeglass 12 Marginal surface is connected to the top surface of the microscope base 24, bears against on the microscope base 24, is supported by the microscope base 24, and each institute It states internal optics eyeglass 11 and each external optical eyeglass 12 is arranged on the photosensitive path of the sensitive chip 21.
