Specific embodiment
To keep the technical problems solved, the adopted technical scheme and the technical effect achieved by the invention clearer, below
In conjunction with attached drawing and pass through specific embodiment to further illustrate the technical scheme of the present invention.
A kind of camera module is present embodiments provided, can be used for mobile phone, tablet computer and video camera etc. has camera shooting
In the electronic equipment of function.
As shown in Figure 1, camera module includes pcb board 1, imaging sensor 2, voice coil motor 3 and camera lens 4.Image sensing
The setting of device 2 is electrically connected on pcb board 1, and with pcb board 1, so that pcb board 1 can receive the image information of imaging sensor 2, and
Image information is handled.Voice coil motor 3 includes motor base 31 and the motor body 32 being mounted on motor base 31, horse
It is provided with through-hole on up to pedestal 31, centre bore is provided in motor body 32, through-hole is aligned with centre bore.Voice coil motor 3 is fixed
On pcb board 1, and the outside of imaging sensor 2 is covered on, so that the through-hole pair on imaging sensor 2 and voice coil motor pedestal 31
Together.Voice coil motor 3 is connected with camera lens 4, and camera lens 4 can be driven to move along centre bore, to adjust camera lens 4 in camera module
The distance between imaging sensor 2 realizes focusing, to make imaging sensor 2 obtain clearly image.
As shown in Figures 2 and 3, it to obtain better image display effect, is also needed between imaging sensor 2 and camera lens 4
It is provided with optical filter 311.Optical filter 311 can be infrared fileter, such as white glass optical filter, smalt optical filter or resin
Glass filter etc..In other embodiments, optical filter 311 or other optical filters, such as bandpass filter, specifically may be used
Think narrow band filter.
Optionally, the shape of optical filter 311 can be rectangle, naturally it is also possible to be circle or other shapes, as long as can
The received area of imaging sensor 2 is completely covered.
In the prior art, support base is provided on pcb board 1, optical filter 311 is installed by being arranged on support base
Between imaging sensor 2 and camera lens 4.But by the fixed optical filter 311 of setting support base will increase camera module thickness and
Cost restricts the lightening development of the electronic equipments such as mobile phone.
To solve the above problems, optical filter 311 is mounted in voice coil motor 3 in the present embodiment, thus to save branch
Seat is supportted, adult is advantageously reduced, reduces the height of camera module, be conducive to trend of the electronic equipments such as mobile phone to frivolous boundary
Development.
Specifically, as shown in Figure 2 and Figure 4, motor base 31 includes plastic cement seat 312 and optical filter 311.Plastic cement seat 312 is
Centre has the annular base body of through-hole, and optical filter 311 may be mounted on plastic cement seat 312 and block the through-hole of plastic cement seat 312, moulds
Rubber base 312 can pass through injection molding.Optionally, optical filter 311 can be fixed on plastic cement seat 312 by glue sticking, such as
Optical filter 311 is fixed on the top surface or bottom surface of plastic cement seat 312 by glue sticking.Since the top surface of plastic cement seat 312 needs to support horse
Up to main body 32, the bottom surface of plastic cement seat 312 needs to connect with pcb board 1, in order to avoid optical filter 311 is by pressure fragmentation, plastic cement seat
It can be set fluted on 312 top surface or bottom surface, optical filter 311 is arranged in the groove, so that the surface of optical filter 311 is not high
In the surface (top surface or bottom surface) of the corresponding side of plastic cement seat 312, to play the role of protecting optical filter 311.
For the processing technology for simplifying motor base 31, in the present embodiment, optical filter 311 can be put into forming plastic cement seat
The type of 312 injection mold is intracavitary, so that optical filter 311 is embedded into plastic cement seat 312 during forming plastic cement seat 312,
To form integral structure with plastic cement seat 312.
In the present embodiment, it is intracavitary that optical filter 311 is implanted to type when plastic cement seat 312 forms, can with motor base 31 at
It is an integral structure, eliminates subsequent to positioning and assembling procedure when pasting optical filter 311, avoid positioning not because of optical filter 311
Quality that is good and influencing camera module.By the way that optical filter 311 to be embedded on motor base 31, the prior art may be omitted with
In support base, to reduce the height of camera module.
Since motor base 31 needs bearing motor main body 32, to avoid 312 intensity of plastic cement seat in motor base 31 inadequate
Deformation causes 311 stress of optical filter to rupture, and motor base 31 further includes metal plate in the present embodiment, and metal plate embeds and plastic cement
In seat 312, vacancy section is provided on metal plate, vacancy section is aligned with the through-hole of plastic cement seat 312.Motor base 31 has been embedded in gold
Belong to plate, increases the intensity of motor base 31, the thickness of plastic cement seat 312 can suitably be thinned, to reduce camera module
Highly, while the problem that rear bring intensity deficiency is thinned in plastic cement seat 312 is made up.
In the present embodiment, metal plate is identical as optical filter 311, is that the type that is previously implanted is intracavitary, thus with plastic cement seat 312
Form integral structure.Specifically, when processing motor base 31, metal plate and the fixation of optical filter 311 first can be formed into group
Part, it is later that component embedded type is intracavitary, in the marginal position injection molding plastic cement seat 312 of component.Optionally, optical filter 311
It can be fixed on a metal plate by glue sticking.The edge of optical filter 311 can stretch out outside metal plate, can also be in metal plate
On surface, as long as optical filter 311 can block through-hole.When injection molding, injected plastics material connects with metal plate and optical filter 311 respectively
Metal plate, optical filter 311 and plastic cement seat 312 after molding are formed integral structure by touching.
The surface of metal plate is also provided with adhesive insulation layer, and optical filter 311 can be adhered on adhesive insulation layer, saves
Fixed glue has been removed, the fixed reliability of optical filter 311 is improved.Optionally, adhesive insulation layer can be with whole tables of covered metal plate
Face can also be only arranged in the position contacted with optical filter 311.
Metal plate can be made of the pure metal material such as copper, aluminium in the present embodiment, can also by steel alloys such as stainless steels or
The alloy materials such as aluminium alloy are made, as long as meeting certain intensity.Optionally, the thickness of metal plate can be 0.05-
0.15mm, such as 0.05mm, 0.07mm, 0.1mm, 0.12mm, 0.15mm.
When preparing metal plate, metal material can be struck out by certain thickness plate by precise punching die, and will
Plate reel packaging.Later, by plate stamping at the multiple metal plates being continuously arranged, and metal plate is surface-treated, i.e.,
It is coated with adhesive insulation layer.By multiple continuous metal plate reel packagings in case injection molding uses.It, will be continuous when injection moulding plastic seat 312
Multiple metal plate embedded types it is intracavitary, pass through the suitable multiple motor bases 31 being continuously arranged of injection molding machine injection molding.Finally
It is cut out by guillotine in multiple motor bases 31.
It is connect for convenience of motor base 31 with motor body 32, mounting structure, mounting structure is additionally provided on plastic cement seat 312
For connecting motor base 31 and motor body 32.Specifically, mounting structure may include positioning column, correspond in motor body 32
It is provided with location hole, positioning column is caught in the connection that positioning hole realizes motor base 31 and motor body 32,31 He of motor base
Motor body 32 can also be further adhesively fixed by glue.
The above is only a preferred embodiment of the present invention, for those of ordinary skill in the art, according to the present invention
Thought, there will be changes in the specific implementation manner and application range, and the content of the present specification should not be construed as to the present invention
