Abstract
The invention provides a camera, comprising a lens module, a front cover and a correction gasket, wherein the lens module and the front cover are connected by a thread structure, the correction gasket is located between the lens module and the front cover, and the correction gasket is a foam gasket. According to the camera provided by the invention, since the foam has certain elasticity and large porous compression, when the lens module and the front cover are connected by the thread structure, the success rate of adjusting the eccentricity is greatly improved.
Description
Technical field
The present invention relates to photographic head field.
Background technology
Lens module and protecgulum use silica gel material packing ring, but due to the difference of camera system, it is necessary to different-thickness packing ring and front cover match support lens module.Investigate 8 platform project to find: having the sealing ring of 4 kinds of different-thickness, wherein the module of poor fit has 4 groups, and almost each module needs newly to open a set of sealing ring mould.It is additionally, since dimensional tolerance reason, it may appear that packing ring coordinates loose or tight problem when assembling.
Current sealing ring scheme is primarily present following two problem:
1. the same sealing ring poor compatibility to different camera systems；
2. same sealing ring coordinates same camera system concordance poor, there is design risk.
For example, the problem mating concordance difference for same camera system, it is carried out tolerance dimension chain and is calculated as follows:
Lens module tolerance: ± 0.3 (mm)
Flange back focal length tolerance: 0 (mm) (here for focusing, so theoretical value tolerance is 0 (mm))
Sensor size and SMT tolerance: ± 0.1 (mm)
Protecgulum dimensional tolerance: ± 0.1 (mm)
Gasket thickness tolerance: ± 0.1 (mm)
Therefore, under current camera structure design, gasket thickness compensation range is: ± 0.6mm.
For the silicone gasket of 0.75mm, actual measurement can be compressed to 0.6mm, and namely packing ring can compensate for scope and only has 0.15mm, does not reach far away the calculated value of 1.2mm.
Silica gel material is calculated with the compressible amount of 20%, reach 1.2mm deflection, silicone gasket thickness needs to reach 6mm, consult related data, depth-width ratio is less than 1.5 guarantees and compresses not unstability, therefore silica gel sealing gasket width needs 4mm, and size now can not meet the requirement of structure.Simultaneously as volume compression invariant feature, material can toward periphery flowing when extruding for silica gel, and silica gel and case ring that when amount of compression is bigger, extruding is flowed out can assemble by interference effect, also affect outward appearance simultaneously.
With reference to automatic production line technical process: first focus, then eccentric.Production process there is a problem in that, focusing eccentric can be normally carried out when camera structure coordinates compact；When camera structure matching loose, focusing can be normally carried out, but due in eccentric process lens module rock and resolution required for being unable to reach eccentric causes eccentric failure, and mechanical whorl coordinates and is difficult to ensure what lens module did not rock.
In sum, when mounted lens module and protecgulum, owing to gasket thickness compensation range is little, when using helicitic texture to connect lens module and protecgulum, eccentric failure easily occurs due to rocking of lens module.
Summary of the invention
It is an object of the invention to provide and a kind of be not easy the photographic head that eccentric is failed.
Another one purpose is in that, solves the problem that different camera systems needs different seal washers and front cover match.
First providing a kind of photographic head, adopt helicitic texture to connect including lens module, protecgulum and rectification packing ring, described lens module and protecgulum, described rectification packing ring is between lens module and protecgulum, and described rectification packing ring is foam packing ring.
With marine glue on described helicitic texture.
Described helicitic texture is through correcting packing ring.
Reoffer the application in photographic head packing ring of a kind of foam packing ring according to demand.
Described foam packing ring replaces the silicone gasket between lens module and protecgulum.
Described lens module and protecgulum adopt helicitic texture to connect, and are coated with marine glue.
Structure is analyzed it can be seen that be coated with fluid sealant in lens module and protecgulum thread pitch can play the waterproof action to photographic head module.But owing to glue can not solidify immediately, can rock when lens module transmits between station, it is therefore desirable to one can support and prevent the structure that lens module tilts, and this structure has bigger tolerance compensation capacity simultaneously.
During foam compression, there is certain elasticity, it is possible to play the effect supporting lens module.Finding it addition, certain foam is compressed test, foam thick for 2.55mm can be compressed to 0.65mm, and decrement can reach 75%.If reaching the 1.2mm decrement of requirement, foam thickness needs 1.6mm., the test of foam compressive stability being found, even if owing to its porosity characteristic can also remain stable in bigger depth-width ratio (actual measurement sample is about 2.1) time, now the width of foam has only to 0.8mm meanwhile.Therefore, work supports and correcting lens module is structurally feasible to adopt foam to correct packing ring (such as wide 0.8mm, high 1.6mm).
The invention have the advantages that
1. same camera system tolerance compensating yield can be reached 100% by foam rectification packing ring in theory；
2. the compatible raising of pair different camera systems；
3., in subsequent project development process, in the plan-validation non-die sinking stage, utilize existing protecgulum and foam rectification packing ring cooperation can mate more multi-camera system and debug.That is, owing to foam corrects packing ring compensation range greatly, it is more suitable for the different camera systems debugging of development.
4. the present invention utilizes foam to have certain elasticity and the big characteristic of porous decrement so that when using helicitic texture to connect lens module and protecgulum, the success rate of eccentric increases substantially.
