Description
Technical field
The present invention relates to a kind of optical system, especially a kind of camera lens module and assemble method thereof.
Background technology
Along with the development of camera technique, the camera lens module is widely used in the camera head of various uses, and the camera lens module generally comprises lens barrel, microscope base and is contained in elements such as eyeglass, spaced ring and worry mating plate in the lens barrel.
In the camera lens module, the lens barrel outer peripheral face is provided with external thread, and microscope base is provided with the internal thread that matches with external thread, and by internal thread and external thread, lens barrel can move up and down in microscope base and realize the purpose of zoom or focusing.During assembling, elder generation is microscope base fixedly, makes lens barrel go into microscope base from the thing sidespin then.Lens barrel, microscope base and their fit, easily since the screw thread fragment that external thread and internal thread produce because of friction when assembling drop between the element that lens barrel accommodates, make contiguous eyeglass or infrared fileter adhere to foreign matter, thereby easily influence the imaging effect of camera lens.
Summary of the invention
In view of this, providing a kind of foreign substance pollution eyeglass that prevents is necessity with camera lens module and the assemble method thereof that guarantees imaging effect in fact.
A kind of camera lens module, it comprises microscope base and is contained in the interior lens barrel of described microscope base, described microscope base has internal thread near the part as side, described microscope base has first partes glabra in the part near the thing side, described lens barrel has the external thread that is used for described screw-internal thread fit near the part as side, described lens barrel has second partes glabra that is used for described first partes glabra applying in the part near the thing side, the internal diameter of the corresponding described microscope base of described first partes glabra is less than the internal diameter of the corresponding described microscope base of described internal thread, and the external diameter of the corresponding described lens barrel of described second partes glabra is less than the external diameter of the corresponding described lens barrel of described external thread.
A kind of assemble method of camera lens module, it comprises: lens barrel and microscope base are provided, described microscope base has internal thread near the part as side, described microscope base has first partes glabra in the part near the thing side, described lens barrel has the external thread that is used for described screw-internal thread fit near the part as side, described lens barrel have near the part of thing side be used for the described first partes glabra iron and second partes glabra, the internal diameter of the corresponding described microscope base of described first partes glabra is less than the internal diameter of the corresponding described microscope base of described internal thread, and the external diameter of the corresponding described lens barrel of described second partes glabra is less than the external diameter of the corresponding described lens barrel of described external thread; Fixed lens barrel; With microscope base by on the internal thread part fit lens barrel; Keep lens barrel motionless, the rotation microscope base makes first partes glabra, second partes glabra of fitting.
Compared with prior art, the external diameter of the partes glabra of the lens barrel of the embodiment of the invention is less than the internal diameter of the partes glabra of the external diameter of external thread part, the microscope base internal diameter less than internal thread, thereby the fragment that makes friction between the partes glabra and produce drops between screw thread, therefore, the eyeglass in the lens barrel is difficult for adhering to foreign matter and the imaging effect that influences the camera lens module; In the assembling process, from the partes glabra assembling, also can obtain above-mentioned effect earlier.
Description of drawings

Fig. 2 is the exploded view of embodiment of the invention camera lens module.
Fig. 3 is the cut-open view of III-III line among Fig. 1.
Embodiment
See also Fig. 1, Fig. 2 and Fig. 3, the camera lens module 10 that the embodiment of the invention provided comprises microscope base 11, lens barrel 12 and focusing ring 13.
Microscope base 11 is the cylindrical shell of hollow, and it comprises that first end 11a is the first smooth partes glabra 111 near the first end 11a of thing side with near the second end 11b as side, and the second end 11b is provided with internal thread 112.The internal diameter of first partes glabra, 111 corresponding microscope bases 11 is less than the internal diameter of internal thread 112 corresponding microscope bases 11.
Focusing ring 13 comprises the focusing post 132 of body 131 and outstanding body 131, and the quantity of focusing post 132 is identical with the quantity of breach 124.Post 132 alignment notch 124 of will focusing, axially firmly slight along lens barrel 12, after hearing the sound of " click ", prove that focusing ring 13 and lens barrel 12 have fastened, just can make lens barrel 12 in microscope base 11, move up and down focusing or the zoom function of realizing camera lens module 10 thereby rotate focusing ring 13.When unloading focusing ring 13,, can take off focusing ring 13 along axially drawing outward gently of camera lens module 10.
At assembling camera lens module 10, use clamping device to cooperate draw-in groove 123 that lens barrel 12 is fixing, the second end 11b with microscope base 11 is linked on the lens barrel 12 via second partes glabra 121 then, keeps lens barrel 12 motionless rotation microscope bases 11, puts in place up to lens barrel 12 and microscope base 11 assemblings.Along with the rotation of microscope base 11, first partes glabra 111 touches second partes glabra 121 and fits tightly, and at this moment, can play the direction of motion of guiding internal thread 112 and external thread 122.
In microscope base 11 rotating processes, along with second partes glabra 121 progresses into first partes glabra 111, external thread 122 contacts with internal thread 112, the fragment that first partes glabra 111 and second partes glabra 121 produce because of friction drops between external thread 122 and internal thread 112, so the eyeglasses in the lens barrel 12 are difficult for adhering to foreign matters and the imaging effect that influences camera lens module 10.
Be understandable that those skilled in the art also can do other variation etc. and be used for design of the present invention in spirit of the present invention, as long as it does not depart from technique effect of the present invention and all can.The variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
