Description
Technical field
The present invention relates to a kind of manufacture method of lens barrel and adopt the camera lens module of this lens barrel.
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 combines with various portable electron devices such as mobile phone, computing machine etc., more obtains numerous consumers' favor.
The camera lens module generally includes the camera lens module and is contained in optical element in the camera lens module.Described optical element comprises eyeglass, optical filter, and in order to the distance member of interval eyeglass and optical filter, as spaced ring etc.
Please refer to Fig. 1, typical camera lens module 10, it comprises a lens barrel 11; The eyeglass of a plurality of different sizes is as one first eyeglass 141, one second eyeglass 142 and a prismatic glasses 143; A plurality of spaced rings that are set in turn between eyeglass are as one first spaced ring 131, one second spaced ring 132 and one the 3rd spaced ring 133; And cutoff filter 12.Described lens barrel 11 comprises a plurality of running through mutually and one first accepting hole 151, one second accepting hole 152 and one the 3rd accepting hole 153 that size is arranged in order, to hold described first spaced ring 131, second spaced ring 132, the 3rd spaced ring 133, described first eyeglass 141, second eyeglass 142, prismatic glasses 143 and a cutoff filter 12.Described first accepting hole 151, second accepting hole 152 and one the 3rd accepting hole 153 are cylindrical hole, and its aperture (figure does not show) size is corresponding with diameter (figure does not show) size of described first eyeglass 141, second eyeglass 142 and prismatic glasses 143 respectively.During assembling, described first eyeglass 141, second eyeglass 142 and the prismatic glasses 143, and described first spaced ring 131, second spaced ring 132 and the 3rd spaced ring 133 successively interval group be loaded in described first accepting hole 151, second accepting hole 152 and the 3rd accepting hole 153, described first spaced ring 131, second spaced ring 132 and the 3rd spaced ring 133 between this first eyeglass 141, second eyeglass 142 and prismatic glasses 143 with at interval first eyeglass 141, second eyeglass 142 and the prismatic glasses 143.Cutoff filter 12 is arranged on the rear end of lens barrel 11.
The center line of described first accepting hole 151, second accepting hole 152 and the 3rd accepting hole 153 and center line M (as shown in Figure 1) conllinear of lens barrel 11.Define described first eyeglass 141, the optical axis of second eyeglass 142 and prismatic glasses is respectively primary optic axis a, the second optical axis b and the 3rd optical axis c, when described first eyeglass 141, second eyeglass 142 and prismatic glasses 143 are that desirable eyeglass (also is first eyeglass 141, the geometric center lines of second eyeglass 142 and prismatic glasses 143 (indicate) respectively with corresponding primary optic axis a, the second optical axis b and the 3rd optical axis c conllinear) time, with described first eyeglass 141, second eyeglass 142 and the prismatic glasses 143, and described first spaced ring 131, second spaced ring 132 and the 3rd spaced ring 133 are assembled into camera lens module 10, at this moment, the center line M of described lens barrel 11 and described primary optic axis a, the second optical axis b and the 3rd optical axis c overlap, and also are described primary optic axis a, there is not position deviation between the center line M of the second optical axis b and the 3rd optical axis c and lens barrel 11.
Yet, because mismachining tolerance, make the influence of the factors such as shrinkage character of the not enough and lens materials of the precision of mould of eyeglass, be easy to occur deviation between the geometric center lines of eyeglass and its optical axis, as shown in Figure 2, the optical axis a of described first eyeglass, the optical axis b of second eyeglass and the optical axis c of prismatic glasses respectively with the geometric center lines A of this first eyeglass 141, position deviation amount α appears between the geometric center lines B of second eyeglass 142 and the geometric center lines C of prismatic glasses 143, β and γ, this will cause assembling the optical axis a of first eyeglass 141 of rear lens module 10, occur different position deviations between the center line M of the optical axis b of second eyeglass 142 and the optical axis c of prismatic glasses 143 and lens barrel 11, thereby have influence on the whole optical property of assembling rear lens module 10.
Common method of adjustment is by adjusting the precision of the mould of making eyeglass, make first eyeglass of making 141, the geometric center lines A of second eyeglass 142 and prismatic glasses 143, B and C respectively with its optical axis a, b and c overlap, reach the optical axis a of first eyeglass 141 of revising camera lens module 10, the effect of the position deviation between the center line M of the optical axis b of second eyeglass 142 and the optical axis c of prismatic glasses 143 and lens barrel 11, but because the accuracy requirement of the mould of making eyeglass is higher, use this method will spend long time and higher cost, be unfavorable for enhancing productivity.
