Description
[technical field]
The invention relates to a kind of structure for assembling lens module, be meant a kind of package assembly that can easy-disassembling-assembling small-sized lens assembly especially.
[background technology]
Existing mobile lens module as shown in Figure 1, this camera lens module 10 comprises a lens assembly 12 and a circuit board 14, this lens assembly 12 is made up of a bearing 13 and several interior eyeglass (not shown) thereof.Be convexly equipped with some reference columns 16 in the bottom of bearing 13,14 correspondences of circuit board are provided with some perforation 18, when assembling lens assembly 12 and circuit board 14, reference column 16 is passed perforation 18, and make with hot melting mode to form projection 20 behind reference column 16 hot melts and be coated on outside the perforation 18, reach the effect of lens assembly 12 and circuit board 14 secure bond.
But this design that produces the projection combination with hot melt, there is certain problem, at first be to study the stage at the sample that product is a large amount of before producing, the bearing 13 of lens assembly 12 and reference column 16 all are to be made by metal material, so can not therefore can't verify the correctness of this integrated structure design in the stage that studies sample in advance with utilizing hot melting mode to fix reference column 16 and boring a hole 18; On the other hand, in the volume production stage, bearing 13 reference column 16 behind hot melt promptly can not be disassembled, if need disassembling lens module 10 with the cleaning foreign matter or when analyzing poor prognostic cause, often must not damage the dependent part product, cause the cost waste and when disassembling, be easy to generate dust particle because of easily-disassembled; Moreover, because of hot melt in conjunction with and have a disappearance of heavy industry difficulty.In addition, the camera lens overall appearance because of after bearing high temperature hot melt, is destroyed and its dependent part product are produced easily.
Therefore, for the benefit of volume production is necessary to propose a kind of new camera lens module fixed sturcture, to overcome above-mentioned shortcoming of the prior art.
[summary of the invention]
Fundamental purpose of the present invention is to provide a kind of and is beneficial to assembling and disassembles, and the structure for assembling lens module of easy heavy industry.
Another object of the present invention is to provide a kind of and guarantee that camera lens module is not destroyed by high temperature, effectively promotes the structure for assembling lens module of goods yield.
A further object of the present invention is to provide a kind of and can decreases lapse rate and reduce dust particle by reduction portion product, and then effectively promotes the assembling yield and reach the structure for assembling lens module that reduces cost.
For achieving the above object, the present invention proposes a kind of structure for assembling lens module, it comprises that one is provided with the substrate of some pilot holes, one is provided with the lens assembly and the plurality of fixed assembly of some reference columns, the external diameter of each reference column is less than the aperture of each pilot hole, to wear this pilot hole by correspondence and to have a gap with the hole wall of this pilot hole, the aforementioned fixation assembly corresponds respectively to pilot hole and reference column, each fixation kit comprises a lamellar body and a collar flange, collar flange is inserted in the aforementioned gap combines closely this reference column and this pilot hole, and this lamellar body closely is covered in outside this pilot hole, and then this substrate and this lens assembly are securely fitted together.
Compared with prior art, the present invention utilizes the design of flexible fastening assembly in conjunction with bearing and circuit board, a kind of camera lens module fixed sturcture of disassembled and easy heavy industry is provided, not only effectively overcome the disappearance that existing assembling is complicated and heavy industry is difficult, and because the present invention need not close in the elevated temperature heat clinkering, so can guarantee that camera lens module is not destroyed by high temperature, effectively promotes the goods yield.In addition, structure for assembling lens module provided by the invention, because its easy heavy industry, so can decrease lapse rate and reduce dust particle by reduction portion product, and then can effectively promote the assembling yield and reach the effect that reduces cost.

Fig. 2 is the three-dimensional exploded view of camera lens module of the present invention.
Fig. 3 is the structure cut-open view of camera lens module of the present invention.
[embodiment]
Please join Fig. 2 and shown in Figure 3, be respectively three-dimensional exploded view of the present invention and assembled sectional view thereof, camera lens module 30 of the present invention comprises a substrate 32 and a lens assembly 34.This lens assembly 34 comprises a bearing (Holder) 340 and mirror cell's module 342, and several optical mirror slip (not shown) are installed in mirror cell's module 342.
This substrate 32 is a circuit board, the dust head is a printed circuit board (PCB), it offers four pilot holes 36, bearing 340 bottoms of this lens assembly 34 then convex with four reference columns 38 corresponding to aforementioned pilot hole 36, and the external diameter of each reference column 38 is less than the aperture of each pilot hole 36, and there is an annular gap in the hole wall that reference column 38 wears by pilot hole 36 backs and pilot hole 36; Other has four fixation kits 42 to correspond respectively to pilot hole 36 and reference column 38, and the material of fixation kit 42 is generally elastic material, for example the material of tool such as rubber or plastics retractility.Each fixation kit 42 comprises a lamellar body 44 and a collar flange 46, with in the gap of being inserted in 36 of reference column 38 and pilot holes by this collar flange 46 and this lamellar body 44 closely is covered in outside this pilot hole 36, and combine closely reference column 38 and pilot hole 36 fixing.
When assembling this camera lens module 30, provide a lens assembly 34 that has assembled mirror cell's module 342 and bearing 340 earlier; Then four reference columns 38 of bearing 340 bottoms of lens assembly 34 are aimed at four pilot holes 36 of substrate 32, make each reference column 38 pass each pilot hole 36 of substrate 32, more aforementioned flexible fixation kit 42 is inserted in the annular gap of 36 of reference column 38 and pilot holes respectively.Because fixation kit 42 is an elastic material, so after the collar flange 46 of fixation kit 42 is inserted in this annular gap, utilize fixation kit 42 elasticity and in collar flange 46, the effect that the periphery footpath respectively has compressive stress, and with positive pressure and reference column 38 wringing fits of interior Zhou Jing, the positive pressure and substrate 32 wringing fits in periphery footpath, can make fixation kit 42 and reference column 38,36 of pilot holes reach closely cooperate fixing, lamellar body 44 by fixation kit 42 closely is covered in outside the pilot hole 36 simultaneously, and then lens assembly 34 and substrate 32 closely be fixed together, and be assembled into a camera lens module 30.
Wherein, camera lens module 30 of the present invention also can be applicable on the compact electronic device of camera lens modules or other tool camera function except being applied to the mobile lens module.
Therefore, can not the property disassembled different from existing hot melt fixing structure, the present invention utilizes flexible fastening Assembly provides a camera lens module disassembled and easy heavy industry fixing knot in conjunction with the design of bearing and circuit board Structure not only effectively overcomes the disappearance that existing assembling is complicated and heavy industry is difficult, and because the present invention need not high temperature The hot melt combination is not destroyed by high temperature so can guarantee camera lens module, effectively promote the goods yield. In addition, originally The structure for assembling lens module that provides of invention because its easy heavy industry, decreases lapse rate and subtracts so can reduce component The dust particle that produces when disassembling less, and then can effectively promote the assembling yield and reach the effect that reduces cost.
