Description
Technical field
The present invention relates to the optical lens processing procedure, relate in particular to a kind of lens cone rotating-in device and method.
Background technology
Along with development of multimedia technology, digital camera, video camera and the mobile phone that has a camera are favored by consumers in general more and more, when the image quality of people's logarithmic code camera, video camera and mobile phone cam shot object proposed requirements at the higher level, logarithmic code camera, video camera and the lightening of products such as mobile phone that has a camera were also had higher requirement.
In the production run of camera module, at first optical element der group such as eyeglass, support column, spaced ring and optical filter are gone into lens barrel, and then lens barrel is screwed in the microscope base.If lens barrel has shift phenomenon when screwing in, can cause imaging that the situation of skew is arranged; If lens barrel and microscope base be not to the heart when screwing in, can cause the destruction of thread when then screwing in and cause the deficiency that screws in moment.These phenomenons all can influence the production yield of camera module.And traditional manual method that screws in lens barrel is difficult to avoid these problems.
Summary of the invention
In view of this, be necessary to provide a kind of lens barrel that can improve the assembling yield to screw in the device and method of microscope base.
A kind of lens cone rotating-in device comprises lens barrel anchor clamps and microscope base rotating disk.Described microscope base rotating disk is used for fixing microscope base and drives its rotation, and described lens barrel anchor clamps are used for the gripping lens barrel.Be respectively arranged with aligner transmitting terminal and aligner receiving end on the center of the center of described microscope base rotating disk and lens barrel anchor clamps.Described aligner receiving end is adjusted the position of lens barrel by the lens barrel anchor clamps after receiving the signal that the aligner transmitting terminal sends.
A kind of lens barrel screw-in method may further comprise the steps: at first microscope base is fixed in the microscope base rotating disk, the center of described microscope base rotating disk is provided with the aligner transmitting terminal.With the lens barrel anchor clamps lens barrel is clamped in the top of microscope base then, the center of described lens barrel anchor clamps is provided with the receiving end of aligner.The aligner transmitting terminal sends signal, aligner receiving end received signal.The lens barrel anchor clamps are finely tuned the lens barrel position according to the signal of aligner receiving end.Last microscope base rotating disk rotation, the lens barrel anchor clamps screw in microscope base with lens barrel.
With respect to prior art, described apparatus and method are separately positioned on the transmitting terminal and the receiving end of aligner on microscope base and the lens barrel anchor clamps, make and can finely tune the position of lens barrel in assembling process, and lens barrel is screwed in lens barrel accurately.The damage of thread takes place to be offset or to cause in the time of therefore can avoiding lens barrel to screw in microscope base, effectively raises the production yield of camera module.

Fig. 1 is the synoptic diagram of the lens cone rotating-in device that provides of the embodiment of the invention.
Fig. 2 is the synoptic diagram of microscope base rotating disk in the lens cone rotating-in device shown in Figure 1.
Fig. 3 is the function connection diagram of the lens cone rotating-in device that provides of the embodiment of the invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is described in further detail.
See also Fig. 1 and Fig. 2, the embodiment of the invention provides a kind of lens cone rotating-in device 10, and it comprises lens barrel anchor clamps 12 and microscope base rotating disk 14.Wherein said lens barrel anchor clamps 12 centers are provided with aligner receiving end 18, and described microscope base rotating disk 14 centers are provided with aligner transmitting terminal 16.Lens barrel anchor clamps 12 are used for gripping lens barrel 20, and microscope base rotating disk 14 is used for fixing microscope base 22 and drives its rotation.
Described lens barrel anchor clamps 12 comprise lens barrel clamping part 120 and mechanical arm 122.Described lens barrel clamping part 120 is a cylindrical hollow configuration.The inwall of described lens barrel clamping part 120 1 ends is provided with the grinding tooth 124 that is complementary with lens barrel 20, and described grinding tooth 124 matches with the dentalation of lens barrel 20 outsides when gripping lens barrel 20, is used for fixing and gripping lens barrel 20.Described mechanical arm 122 is fixed on the other end of lens barrel clamping part 120, is used to control the direction that lens barrel clamping part 120 moves, thereby lens barrel 20 is inserted in the microscope base 22.Described aligner receiving end 18 is arranged on the center of mechanical arm 122.
The aligner that the present invention adopts can also can be autocollimation aiming aligner for directly aiming at aligner surely.With autocollimation aiming aligner is example, its principle is to utilize LASER Light Source to be transmitting terminal 16, lens barrel 20 is adjusted into and microscope base 22 collimations, coaxial, and specific practice can receive laser beam and make reflected light by former road return laser light for lens barrel 20 is adjusted to aligner receiving end 18.
The embodiment of the invention also provides a kind of method of utilizing said apparatus to screw in lens barrel, may further comprise the steps.Mechanical arm 122 is at first controlled the top that lens barrel clamping part 120 is clamped in lens barrel 20 microscope base 22, at this moment the aligner transmitting terminal 16 that is arranged on the microscope base rotating disk 14 sends laser beam 24, and described laser beam 24 passes microscope base 22 and lens barrel 20 is set at aligner receiving end 18 receptions on the mechanical arm 122 and converts electric signal to.See also Fig. 1 and Fig. 3, (Central Process Unit CPU) connects aligner receiving end 18, and CPU handles the fine setting that back control mechanical arm 122 is done the X-Y-Z direction to electric signal with CPU (central processing unit).Laser beam 24 is reflected back toward aligner transmitting terminal 16, aligner transmitting terminal 16 is passed to CPU with signal, CPU judges whether laser beam 24 returns aligner transmitting terminal 16 by former road, and then do fine setting according to the Data Control mechanical arm 122 after judging, till CPU judges laser beam 24 and returns by former road fully.Last microscope base rotating disk 14 begins rotation, and lens barrel anchor clamps 12 begin to descend and lens barrel 20 is screwed in the microscope base 22.
With respect to prior art, described device is separately positioned on the transmitting terminal 16 and the receiving end 18 of aligner on microscope base and the lens barrel anchor clamps, can finely tune the position of lens barrel in assembling process, and lens barrel is screwed in lens barrel accurately.The damage of thread takes place to be offset or to cause in the time of therefore can avoiding lens barrel to screw in microscope base, effectively raises the production yield of camera module.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
