For above-mentioned purpose of the present invention, feature and advantage can be become apparent, preferred embodiment cited below particularly and conjunction with figs. elaborate.
Now conjunction with figs. illustrates preferred embodiment of the present invention.
See also Fig. 1 and Fig. 2, optical axis adjustable device 100 mainly includes a holder 110, a framework 120, is adjusted piece 130, one first driving mechanism 140, one second driving mechanism 150 and a projector mechanism 160.
Still as shown in Figures 1 and 2, holder 110 has one second open-work 111, and framework 120 is to be connected in holder 110, is to be arranged in a movable manner among the framework 120 and adjust piece 130.First driving mechanism 140 and second driving mechanism 150 all are to be arranged at outside the framework 120, and all are to be connected in to adjust piece 130, adjust piece 130 and are displaced among the framework 120 according to a first direction A and a second direction B to order about respectively.Specifically, second direction B is perpendicular to first direction A.In addition, as shown in Figure 2, adjust piece 130 and also have one first recess 131 and one second recess 132, and optical axis adjustable device 100 also includes one first flexible member 170, one second flexible member 175, one first keeps out element 180 and one second keeps out element 185, first flexible member 170 and second flexible member 175 are to be arranged at respectively among first recess 131 and second recess 132 of adjusting piece 130, and first keep out element 180 and second to keep out element 185 be to be arranged between first flexible member 170 and the framework 120 respectively and between second flexible member 175 and the framework 120.It should be noted that, the position of first flexible member 170 is the positions with respect to first driving mechanism 140, and first flexible member 170 can be done telescopic moving according to first direction A, and the position of second flexible member 175 is the positions with respect to second driving mechanism 150, and second flexible member 175 can be done telescopic moving according to second direction B.In the present embodiment, first flexible member 170 and second flexible member 175 can be to adopt element such as spring, and first keep out element 180 and second to keep out element 185 can be to adopt element such as steel ball.
In addition, adjust piece 130 and also have an Access Division 133 (as shown in Figure 1) and one first open-work 134 (as shown in Figure 2), Access Division 133 is to form on the edge of first open-work 134.In the present embodiment, because first open-work 134 has circular shape, so the Access Division 133 that forms on first open-work, 134 edges promptly can have annular shape, that is Access Division 133 is annular grooves.
As shown in Figure 1, projector mechanism 160 is to be arranged at outside the holder 110, and is second open-work 111 that is adjacent on the holder 110.More specifically, projector mechanism 160 includes a projector 161 and an image plate 162, and image plate 162 is to be arranged between projector 161 and the holder 110.
In addition, optical axis adjustable device 100 also includes one first tie rod 190 and one second tie rod 195, first tie rod 190 is to be connected between first driving mechanism 140 and the adjustment piece 130, and second tie rod 195 is to be connected between second driving mechanism 150 and the adjustment piece 130.As mentioned above, when forcing first tie rod 190 to advance (moving down) when operation first driving mechanism 140, first tie rod 190 promptly can promote to adjust piece 130 and move to framework 120 inner edges according to first direction A, at this moment, first flexible member 170 that is arranged in first recess 131 is to be in compressed state, and, adjust piece 130 and promptly can move in the other direction because of the elastic restoring force that first flexible member 170 is provided when forcing first tie rod 190 to retreat (moving up) when operation first driving mechanism 140.Similarly, second driving mechanism 150, second tie rod 195 and the function mode of adjusting 130 of pieces are also identical with the function mode of 130 of adjustment pieces with first driving mechanism 140, first tie rod 190.
In addition, in the present embodiment, first driving mechanism 140 and second driving mechanism 150 can be that (but being not limited to) is made of accurate helical structure (the accurate helical structure that for example Mitutoyo produced).Certainly, first driving mechanism 140 and second driving mechanism 150 can also be the driving mechanisms that includes device such as motor.
Below the mode of adjusting the optical axis of a camera lens with optical axis adjustable device 100 will be described.
At first, as shown in Figure 1, one camera lens 200 that will have one first mirror group 210 and one second mirror group 220 is fixed in the holder 110, at this, the first mirror group 210 is connected in earlier the second mirror group 220 in a movable manner, that is the first mirror group 210 can come to combine with the second mirror group 220 a little with elements such as screws earlier.More specifically, the first mirror group 210 is among second open-work 111 that is fixed on the holder 110, the second mirror group 220 is fixed among the Access Division of adjusting on the piece 130 133, and the second mirror group 220 protrudes in first open-work of adjusting on the piece 130 134.It should be noted that, because the optical axis L of camera lens 200 is made of the first mirror group's 210 optical axis and the second mirror group's 220 optical axis, with the second mirror group's 220 optical axis whether the phenomenon that does not overlap is arranged so whether the optical axis L of camera lens 200 is offset the optical axis that will see the first mirror group 210, in other words, if the first mirror group's 210 the optical axis and the second mirror group's 220 optical axis coincidence together, represent that promptly the optical axis L of camera lens 200 is not offset.Then, detect the side-play amount of the optical axis L of camera lens 200 with projector mechanism 160.More specifically, come image plate 162 is penetrated light with projector 161, at this moment, the image on the image plate 162 can pass through the first mirror group 210 and the second mirror group 220 in regular turn, and is incident upon on the second mirror group 220 screen (not shown) outward.Whether overlap by the image on the view screen, can learn whether the first mirror group's 210 optical axis and the second mirror group's 220 optical axis coincide together.When the image on the screen does not overlap, order about with first driving mechanism 140 and second driving mechanism 150 and to adjust piece 130 and be displaced among the framework 120 according to first direction A and second direction B, that is adjust the position of the second mirror group 220 with respect to the first mirror group 210, picture registration on screen together, mean promptly that the first mirror group's 210 optical axis and the second mirror group's 220 optical axis coincide together this moment, or the optical axis L of camera lens 200 has not had the phenomenon of skew.Then, 220 of the first mirror group 210 and the second mirror groups' screw is locked, or the first mirror group 210 and the second mirror group 220 used the UV glue bond, can finish the optical axis adjustment of camera lens 200.
In addition, in the above-described embodiment, first direction A and second direction B all are haply perpendicular to the optical axis L of camera lens 200.
In sum, adjust the optical axis of a camera lens, can improve the light shaft offset phenomenon that camera lens is taken place in processing or assembling back, and then can promote camera lens and produce yield with the optical axis adjustable device 100 of present embodiment.
Though the present invention by the preferred embodiment explanation as above, this preferred embodiment is not in order to limit the present invention.Those skilled in the art without departing from the spirit and scope of the present invention, should have the ability this preferred embodiment is made various changes and replenished, so protection scope of the present invention is as the criterion with the scope of claims.
