Embodiment
One of the present invention embodiment conceptually is shown in Fig. 2.Fig. 2 is the sectional view of camera lens installing mechanism of the use resilient material of one of the present invention embodiment.
Among Fig. 2, sensor 2 is fixed on the substrate 3 by welding or bonding etc.A circle rubber 4 in clamping between camera lens 1 and the substrate 3, passed by screw 5 and screw, fixing.Surface of contact between surface of contact between camera lens 1 and the rubber 4 and rubber 4 and the substrate 3 is in light tight ground and keeps tightlock status forever.
Secondly, in the camera lens installing mechanism of use resilient material of the present invention,, use embodiment to be illustrated for the sensor perturbations method of adjustment, to the method for adjustment of focal plane.
Fig. 3～Fig. 7 be the sensor perturbations of one of the present invention embodiment with to the adjustment figure of focal plane.
Among Fig. 3, screw by screw thread between camera lens fixed mount 6 and the camera lens 1, utilize rotating lens 1, can make camera lens 1 stretch out or retraction.In addition, sensor 2 is fixed on the substrate 3 by welding or bonding etc., makes it and causes tilting because of welding or bonding agent uneven thickness etc.
Among Fig. 4, at first, camera lens 1 is screwed out to the longest, slowly screw in then, make camera lens drop on the outstanding A point of inclination sensor 2 focal plane.
Secondly, as shown in Figure 5, again camera lens 1 is slowly screwed in, make camera lens drop on the back point B of inclination sensor 2 focal plane.At this moment, the focusing position that A is ordered can be lost, and becomes the position that is positioned at A point back.
Secondly, as shown in Figure 6, by the screw 5 that the most close B is ordered is screwed, whole base plate 3 will be that the center of circle begins the door leaf motion with the screw of top, make sensor fixed thereon 2 become to be parallel to while moving forward camera lens to focal plane, that is perpendicular to optical axis.At this moment, because sensor 2 whole reaches can make the focusing position that B is ordered also lose, and become the position that is positioned at B point back.Therefore but because the B point advances comparatively fast, 2 of A, B can become and be positioned on the same vertical plane in the near future, and at this moment, all fog-levels of image that drop on the sensor cover are uniform.Whether evenly can differentiate by naked eyes, or this image input computer be carried out image analysing computer detect by the captured image of sensor.Continue rotary screw, till the fog-level of above-mentioned image is all even.
At last, as shown in Figure 7, camera lens 1 back-out is focused, focal plane is all dropped on the surface of sensor 2 just, just finishing the focusing action up to whole.
Among the above embodiment, though be illustrated in the two-dimensional plane mode by sectional view, but in fact, for example when using 4 screws that camera lens is installed, only need be after focusing occurring on any point of sensor cover, the screw of ambiguous location is the most screwed, when becoming uniform state, all fog-levels of image frame stop to screw, and then rotate and stretch out camera lens, just can obtain comprehensive focusing.
By above-mentioned focusing method, owing to be to make the rubber compression,, needn't worry that also light or dust foreign material etc. invade in the camera lens even therefore do not use light-proofness bonding agent or extra shading member, only need just camera lens to be installed on the substrate by screw.Again,, only need can install by screw because the part number reduces, therefore more easy in the assembling.
