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 voice coil motor pedestal 31 and the motor being mounted on voice coil motor pedestal 31 Main body 32 is provided with through-hole on voice coil motor 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 covers on the outside of imaging sensor 2, so that imaging sensor 2 and voice coil motor pedestal Through-hole alignment on 31.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 shooting The distance between camera lens 4 and imaging sensor 2 in head mould group, realize focusing, to scheme imaging sensor 2 clearly Picture.
To obtain better image display effect, as shown in Fig. 2, also needing to be provided between imaging sensor 2 and camera lens 4 Optical filter 311.Optical filter 311 can be infrared fileter, such as white glass optical filter, smalt optical filter or plexiglas filter Mating plate etc..In other embodiments, optical filter 311 or other optical filters, such as narrow band filter, are specifically as follows narrow Band optical 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 there is 311 positioning accuracy of optical filter by the fixed optical filter 311 of setting support base The problems such as poor, at high cost, intensity difference, optical filter 311 are easily broken and camera module thickness is big restricts the electronics such as mobile phone and sets Standby lightening development.
To solve the above problems, optical filter 311 is embedded into voice coil motor pedestal 31 in the present embodiment, to save The positioning of optical filter 311, assembling procedure, may be omitted with support base in the prior art, advantageously reduce adult, reduction is taken the photograph As the height of head mould group, be conducive to trend development of the electronic equipments such as mobile phone to frivolous boundary.
Specifically, as shown in figures 3 to 6, voice coil motor pedestal 31 includes plastic cement seat 313 and optical filter 311.Plastic cement seat 313 For the intermediate annular base body with vacancy section, optical filter 311 can be embedded in plastic cement seat 313 and block engraving for plastic cement seat 313 Dead zone, plastic cement seat 313 can pass through injection molding.For the processing technology for simplifying voice coil motor pedestal 31, optical filter 311 can be put The type entered to the injection mold of forming plastic cement seat 313 is intracavitary, so that optical filter 311 is embedded in during forming plastic cement seat 313 Into plastic cement seat 313, to form integral structure with plastic cement seat 313.
In the present embodiment, it is intracavitary that optical filter 311 is implanted to type when plastic cement seat 313 forms, can be with voice coil motor pedestal 31 are integrally formed formula structure, eliminate subsequent positioning and assembling procedure, avoid because optical filter 311 position it is bad due to influence camera shooting The quality of head mould group.By the way that optical filter 311 to be embedded on voice coil motor pedestal 31, support in the prior art may be omitted with Seat, to reduce the height of camera module.
Since voice coil motor pedestal 31 needs bearing motor main body 32, to avoid plastic cement seat 313 in voice coil motor pedestal 31 Intensity not enough deforms, and 311 stress of optical filter is caused to rupture, and voice coil motor pedestal 31 further includes metal plate 312 in the present embodiment, gold Belong to plate 312 to be embedded in plastic cement seat 313, through-hole is provided on metal plate 312, through-hole is aligned with the vacancy section of plastic cement seat 313.Sound Coil motor pedestal 31 has been embedded in metal plate 312, increases the intensity of voice coil motor pedestal 31, and the thickness of plastic cement seat 313 can be with It is appropriate to be thinned, to reduce the height of camera module, while making up after plastic cement seat 313 is thinned that bring intensity is insufficient to ask Topic.
In the present embodiment, metal plate 312 is identical as optical filter 311, is that the type that is previously implanted is intracavitary, thus with plastic cement seat 313 form integral structure.It specifically, can be first by metal plate 312 and optical filter 311 when processing voice coil motor pedestal 31 Fixation forms component, later that component embedded type is intracavitary, in the marginal position injection molding plastic cement seat 313 of component.Optionally, Optical filter 311 can be fixed on metal plate 312 by glue sticking.The edge of optical filter 311 can stretch out outside metal plate 312, It can also be on the surface of metal plate 312, as long as optical filter 311 can block through-hole.When injection molding, injected plastics material respectively with Metal plate 312 and optical filter 311 contact, and metal plate 312, optical filter 311 and plastic cement seat 313 after molding are formed integral type Structure.
The surface of metal plate 312 is also provided with adhesive insulation layer, and optical filter 311 can be adhered to adhesive insulation layer On, fixed glue is eliminated, the fixed reliability of optical filter 311 is improved.Optionally, adhesive insulation layer can be with covered metal plate 312 All surfaces, can also only contact with optical filter 311 position setting.
Metal plate 312 can be made of the pure metal material such as copper, aluminium in the present embodiment, can also be 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 312 can be 0.05-0.15mm, such as 0.05mm, 0.07mm, 0.1mm, 0.12mm, 0.15mm.
When preparing metal plate 312, metal material can be struck out by certain thickness plate by precise punching die, and Plate reel is packed.Later, by plate stamping at the multiple metal plates 312 being continuously arranged, and surface is carried out to metal plate 312 Processing, i.e. coating adhesive insulation layer.By multiple continuous 312 reel of metal plate packagings in case injection molding uses.Injection moulding plastic seat 313 When, continuous multiple 312 embedded types of metal plate are intracavitary, pass through the suitable multiple voice coils being continuously arranged of injection molding machine injection molding Motor base 31.It cuts out finally by guillotine in multiple voice coil motor pedestals 31.
It is connect for convenience of voice coil motor pedestal 31 with motor body 32, mounting structure is additionally provided on plastic cement seat 313, installed Structure is for connecting voice coil motor pedestal 31 and motor body 32.Specifically, mounting structure may include positioning column, motor body Location hole is correspondingly arranged on 32, positioning column is caught in the connection that positioning hole realizes voice coil motor pedestal 31 and motor body 32, Voice coil motor pedestal 31 and 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 Limitation.
