The invention provides a lens module assembling device used for assembling optical elements into a lens barrel, comprising a bar body and an optical element clamping unit, wherein the bar body is provided with a first end and a second end which are opposite to each other; the optical element clamping unit is assembled at the first end; and the second end is provided with a horizontal device.
Description
Technical field
The present invention relates to a kind of lens module group assembly device, relate in particular to a kind of in assembling process the lens module group assembly device of capable of regulating optical element levelness.
Background technology
In recent years, along with the development of multimedia technology, the range of application of camera lens module is more and more wider, as is applied in digital camera, video camera and the electronic products such as mobile phone with camera function.People's logarithmic code camera, video camera reach when pursuing miniaturization with the mobile phone of camera function, the quality of image to its object of shooting is also had higher requirement, the image frame of namely wishing shot object is clear, and the image quality of object depends in assembling process to a great extent, and whether the optical axis of each lens in the camera lens module aligns.The people such as Alpheus learn in nineteen ninety-five SPIE system, image metrology the optical axis that has disclosed due to each lens in the camera lens module in the paper " Zoom lens calibration for wind tunnel measurements " of delivering in the fourth session (VideometricsIV) and do not line up the impact that produces.Therefore, the assembling of lens must be quite accurate, with the probability of raising optical axis alignment, thus the image quality of raising camera lens module.
The camera lens module generally includes the elements such as lens barrel (Barrel), microscope base (Holder), lens, spaced ring and optical filter, and wherein, lens are fixed in lens barrel successively along the central axis direction of lens barrel.In the lens module group assembling process, first the elements such as lens, spaced ring are drawn in lens barrel, then adopt tool to assemble the position of each element in lens barrel.
In prior art, usually adopt the position of the element such as pressure bar assembling lens and spaced ring in lens barrel.Described pressure bar is that an end is established reeded column structure.In assembling process, the elements such as lens, spaced ring are placed in groove, then hold pressure bar and put it in lens barrel.And in the assembled by hand process, can make lens with respect to the horizontal plane produce inclination, cause to have deviation between the optical axis of lens, thereby reduce camera lens module yield.
Summary of the invention
In view of this, be necessary to provide a kind of in assembling process the lens module group assembly device of capable of regulating optical element levelness.
A kind of for optical element being assembled into the lens module group assembly device of lens barrel, it comprises barred body and optical element grip unit, described barred body has relative first end and the second end, described optical element grip unit is assemblied in described first end, and described the second end is provided with horizontal device.
Compared with prior art, the lens module group assembly device of the embodiment of the present invention can judge by horizontal device whether whether the direction of motion of optical element parallel with the central shaft of lens barrel, can make the movement locus and being adjusted of Real Time Observation optical element in assembling process guarantee the central axes of optical axis and the lens barrel of optical element, the assembling yield of raising camera lens module.
Description of drawings
Fig. 1 is the overall schematic of embodiment of the present invention lens module group assembly device.
Fig. 2 is the decomposed schematic diagram of embodiment of the present invention lens module group assembly device.
Fig. 3 adopts lens module group assembly device in Fig. 1 with pack into the schematic diagram of lens barrel of lens combination.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
See also Fig. 1, Fig. 2, the lens module group assembly device 10 of the embodiment of the present invention comprises barred body 11, optical element grip unit 12, horizontal device 13 and support 14.
Certainly, horizontal device 13 also can be electrolevel, as inductance type level meter or condenser type level meter.
Certainly, the shape of barred body 11, support arm 141, pillar 142 and base 143 is not limited to the shape in the present embodiment, also can be other shape.
The quantity of support arm 141 is not limited to four, can be three, five etc., and correspondingly, on pillar 142, base 143, spring 144 and barred body 11, the quantity of circular hole 113 also changes thereupon.
During assembling lens module group assembly device 10, first spring 144 is enclosed within thin section 1422 and thin section 1422 and is placed in containing hole 1431, then screw 145 is passed opening 1423 and stretch into interior the second end 1412 with support arm 141 of threaded hole 1413 and be fixed on pillar 142, thereby then the first end 1411 of support arm 141 is placed in the circular hole 113 of barred body 11 and makes barred body 11, grip unit 12 and horizontal device 13 unsettled.
Certainly, also can there be other number of assembling steps to assemble lens module group assembly device 10, for example, first support arm 141 be fixed on barred body 11, then support arm 141 is fixed on pillar 142, at last pillar 142 is fixed on base 143.
as shown in Figure 3, during assembling camera lens module, at first apparatus for assembling 10 assemblings are complete, then lens barrel 20 be fixed in the storage tank 31 on horizontal table 30 and make the central shaft vertical table 30 of lens barrel 20, lens 21 be placed on the suction nozzle 122 of grip unit 12 and make grip unit 12 be positioned at the top of lens barrel 20, apply the pressure that points to worktable 30 on barred body 11, thereby pillar 142 drives barred body 11 to base 143 direction motions under the effect of pressure, grip unit 12 and horizontal device 13 move downward that lens 21 are put into lens barrel 20, remove the pressure that is applied to barred body 11, pillar 142 recovers the original position under the effect of spring 14.
In barred body 11, grip unit 12 and horizontal device 13 move downward process, the movement locus that can judge barred body 11 by the position of bubble 132 in glass tube 131 in eye-level device 13 whether with the central axes of lens barrel 20.When the central shaft of movement locus and lens barrel 20 is not parallel, adjust the position of screw 145 in opening 1423 to adjust the position of support arm 141 relative pillars 142, make the central axes of movement locus and lens barrel 20.
Because whether whether the direction of motion that can judge lens 21 by horizontal device 13 parallel with the central shaft of lens barrel 20, the movement locus that can make Real Time Observation lens 21 in assembling process improves the assembling yield of camera lens module with the optical axis of guaranteeing lens 21 and the central axes of lens barrel 20.
In addition, those skilled in the art can also do other variation in spirit of the present invention, and certainly, the variation that these are done according to spirit of the present invention is within all should being included in the present invention's scope required for protection.
