Referenced herein " embodiment " is it is meant that the special characteristic, structure or the characteristic that describe can wrap in conjunction with the embodiments It is contained at least one embodiment of the application.Each position in the description occur the phrase might not each mean it is identical Embodiment, nor the independent or alternative embodiment with other embodiments mutual exclusion.Those skilled in the art explicitly and Implicitly understand, embodiment described herein can be combined with other embodiments.
Referring to Fig. 1, for the structural representation of optical filter box 100 in the embodiment of the application one.The optical filter box 100 can To apply in the CCD camera assembly of mobile terminal, either in Ipad CCD camera assembly or in wearable device.The optical filtering Piece component 100 includes base 10 and the optical filter 20 being connected with base 10.
Specifically, a part at least opposite sides of optical filter 20 is embedded in base 10, and it is integrally formed with base 10. The position that optical filter 20 is integrally formed combination with base 10 is joint portion 12.
In order to preferably illustrate the improvement of the application, referring now to Fig. 2, for the knot of optical filter box 100a in the prior art Structure schematic diagram.Optical filter 20a end is pasted onto on base 10a by the adhesive layer 80 being coated on base in the prior art. Contact site using such structure optical filter 20a and base 10a is limited, is typically only the general face of optical filter 20a ends Product, therefore adhesion is poor, easily comes off, and easily causes optical filter 20a to crush.Further, optical filter 20a and base 10a Joint portion length b1 it is smaller, it is not strong with reference to dynamics.
End 22 in the application due to optical filter 20 uses integrally formed structure with base 10, compared with the prior art originally Application causes the ring Zhou Jun of the end 22 of optical filter 20 to be snapped tight against by the inwall of base 10 using integrally formed structure, relatively Prior art can strengthen the adhesion between the two well by way of adhesive layer 80 is pasted, substantially reduce optical filter 20 because The probability that adhesion is small and comes off or crushes.
Further, the tip lengths that optical filter 20 is located in base 10 are more than or equal to 0.25mm.Using such structure, filter Mating plate 20 and the length in base 10 are much larger than the combination length of prior art, can be further ensured that the adhesion of the two Degree.
Optical filter 20 plays a part of filtering light wave.Specifically, optical filter 20 can be smalt, white glass and resin Piece one kind therein.
In one embodiment, the thickness of the wherein side of joint portion 12 is 0.15-0.18mm.Referring to Fig. 2, in the prior art, knot The thickness a1 of conjunction portion 12a sides corresponding with the application is generally 0.3-0.38mm.Optical filter can be made using such setting Component 100 is overall to be thinned, and then integrally to be made more frivolous using the equipment of the optical filter box 100, or vacating space For setting miscellaneous part.Specifically, the thickness of the wherein side of joint portion 12 can be 0.15mm or 0.18mm.
In one embodiment, optical filter 20 is rectangle, and the end of at least opposite sides of optical filter 20 is embedded in base 10, It can certainly be that the ends of three sides or four sides is embedded in base 10, strengthen both adhesions.
In another embodiment, optical filter 20 is circular or ellipse, the ring circumferential portion of the optical filter 20 are embedded at base 10 It is interior.Due in the embedded base 10 in all ends on the ring week of optical filter 20, being snapped tight against by the inwall of base 10, therefore can Ensure the adhesion of optical filter 20 and base 10 well.
Referring to Fig. 3, the application also provides a kind of shooting head mould of the optical filter box 100 including described by above example Group 200.The camera module 200 also includes camera lens 30, and the camera lens 30 is oppositely arranged with optical filter 20.Due to optical filter 20 and bottom Seat 10 can lift the durable performance of shooting throwing module 200 using integrally formed structure.In one embodiment, the shooting head mould Group 200 also includes the motor 70 being connected with camera lens 30.Motor 70 is used to drive camera lens 30 to stretch on the thickness direction of optical filter 20 Contracting movement, such as during screen focusing is taken pictures or shot to camera module 200.
Referring also to Fig. 4, in an embodiment, the chip 40 and substrate that module 200a also includes being stacked are thrown in the shooting 50, the end set conductive pin 60 that chip 40 is connected with substrate 50 is electrically connected with realizing.Specific conductive pin 60 needs Protruded towards the direction of camera lens 30, wherein, optical filter 20 and end face 24 of the joint portion 12 of base 10 away from the side of camera lens 30 are remote Optical filter 20 is centrally disposed, to form avoiding space 26.The avoiding space 26 is used to house conductive pin 60.Using such knot Structure, because length of the joint portion 12 close to the side of camera lens 30 is not reduced, appropriate reduces joint portion 12 away from camera lens 30 The length of side, ensure optical filter 20 is combined with base 10 dynamics relatively by force on the premise of vacate avoiding space 26, led for setting Electric pin 60, the part protruded for housing conductive pin 60 towards camera lens 30.Therefore structure as using can make shooting Head mould group 200a is integrally made more frivolous.Specific conductive pin 60 can be gold thread or the wire of other materials.
In another embodiment, referring to Fig. 5, camera module 200b joint portion 12 close to the side of chip 40 thickness by by The end face 24 at the nearly center of optical filter 20 gradually increases towards away from the center position of optical filter 20.It can not subtracted using such structure Few optical filter 20 is with being that conductive pin 60 forms certain accommodation space 28 on the premise of the bonded area of base 10.Namely ensureing On the premise of there is stronger adhesion between optical filter 20 and base 10, while whole camera module 200b is made thinner.
Referring to Fig. 6, the application also provides a kind of terminal 300, and the terminal 300 includes the camera described by above example Module, such as 200,200a and 200b.The terminal 300 can be the devices such as mobile phone, Ipad, or wearable device.
Referring to Fig. 7, the application also provides a kind of optical filter box preparation method.This method includes：
101：The end of optical filter is put into mould.
102：By being molded the integrally formed base in end formed with optical filter in mould.
Wherein, in an embodiment, length of the end more than 0.25mm of optical filter is put into mould, to ensure that base is formed The end insertion integrally formed length of base of optical filter is more than or equal to 0.25mm afterwards.
The structure of the optical filter box prepared described in this method is consistent with the optical filter box described by various embodiments above.
Referring to Fig. 8, the application also provides a kind of camera module preparation method.This method comprises the following steps：
201：The end of optical filter is put into mould.
202：By being molded the integrally formed base in end formed with optical filter in mould.
203：In optical filter opposite side, camera lens is set.
The structure of the camera module prepared described in this method is consistent with the camera module described by various embodiments above.
The optical filter box or camera module that above method makes, because optical filter therein and base use one The adhesion being designed between both guarantees of shaping, substantially reduces the probability that optical filter comes off from base, crushed.
Presently filed embodiment is the foregoing is only, not thereby limits the scope of the claims of the application, it is every to utilize this The equivalent structure or equivalent flow conversion that application specification and accompanying drawing content are made, or directly or indirectly it is used in other correlations Technical field, similarly it is included in the scope of patent protection of the application.
