Background technology
In the optical imagery product, for example digital camera, scanner ... Deng, for obtaining imaging effect accurately, must guarantee the camera lens of printing opacity and focusing as far as possible and be subjected to the relative position between the photoimaging device (for example image sensor of CCD or CMOS etc.) accurate.
Yet for now, because technology limitation such as the encapsulation of optical element and processing, and the refinement day by day of production Labor Division System etc. is all multifactor, when assembling manufacturer assembles each optical element, if directly each element is assembled into one by common engineering, last often the discovery is difficult to guarantee that the position that concerns of camera lens and imaging device can be very accurate.
For example, wherein contain lens group, reach image sensor at the alike precision optics imaging product of numeral.How its image sensor such as CCD, CMOS etc. can transfer to other specialized vendor after being finished by the production of wafer factory encapsulates, but it is inaccurate that image sensor the time is often located in encapsulation, thereby can cause the axle center of lens group can't accurately be in vertical alignment with the video sensing district center of image sensor.
See also Fig. 1, be a kind of cut-open view of prior art lens lock fixing structure.The practice of this technology is that the fixed base frame 1a of fixed lens is locked by bolt 2a and circuit board 3a, makes this fixed base frame 1a develop this circuit board 3a.Yet because the deflection tolerance of image sensor 4a in the assembling process that utilizes SMT (surface mount technology) piece causes the monolateral fuzzy existing picture of image easily.
See also Fig. 2, be the cut-open view of another kind of prior art lens lock fixing structure.This technology be improve the verticality of the optical axis and the image sensor 4a of camera lens, its practice is that the inboard root edge with fixed base frame 1a contacts interference with image sensor 4a, makes it guarantee verticality.Yet shortcoming is that the piece height tolerance of image sensor 4a itself and SMT (surface mount technology) thereof is big, when amount of interference is big, easily image sensor 4a is damaged by pressure.
As from the foregoing, above-mentioned existing lens lock fixing structure in practical application, obviously has inconvenience and exists with disappearance, and can wait to be improved.
