Abstract
The utility model relates to a camera lens automatic focusing module structure mainly comprising a camera lens group, a fixing seat and an image sensor circuit board, wherein the camera lens group is mounted at one end of the fixing seat, more than two guide poles are arranged at the other end of the fixing seat, movable regulating slide blocks capable of axially moving along the guide poles are mounted on the guide poles, and the image sensor circuit board is arranged on the movable regulate slide blocks; and a stepping motor is mounted on the fixing seat, and the front end of a stepping motor shaft is connected with a screw rod shaft, while the other end thereof is connected to the movable regulate slide blocks in a movable manner. Since the external control system controls the rotation of the stepping motor to drive the regulating slide blocks to axially move along the guide poles, the image sensor circuit board can move relatively to the camera lens group mounted at one end of the fixing seat, i.e. automatic focusing shooting can be realized through regulating and moving the image sensor. The scheme of the utility model has simple structure and convenient installation and regulation, and improves the focusing precision.
Description
Technical field the utility model relates to the optical focusing field, is specifically related to a kind of lens automatic focusing modular structure.
Background technology in the prior art, audio and video products video camera, recording instrument, camera, the employed camera lens focus control of scanning device generally are to rely on the multi-step thread of regulating on the focusing ring, lens combination is produced move axially the realization focusing, or the axial location by certain set of contact lenses in the moving lens, so that object distance can keep the constant realization focusing of image distance when changing.The defective of these two kinds focusing modes is to want the eyeglass in the mobile lens group many, and the camera lens volume is big, and complex structure is installed and adjusted inconvenience.
Summary of the invention the utility model provides a kind of lens automatic focusing modular structure, solves existing focusing lens modular structure complexity, the inconvenient problem of adjusting is installed.
The technical scheme that the utility model is taked is: the utility model mainly comprises lens group, holder, image sensor circuit plate, lens group is installed in holder one end, the other end of holder is provided with plural guide pillar, being equipped with on the guide pillar can be along the axially movable movable adjusting slider of guide pillar, and movable adjusting slider is provided with the image sensor circuit plate.
Adopt the utility model scheme, adjusting slider can drive the image sensor circuit plate and move axially along guide pillar smoothly, by the position of moving image transmitting sensor, makes the focal length of lens group concentrate on realization automatic focusing shooting on the imageing sensor.
Stepper motor also is installed on the described holder, and the step motor shaft front end connects screw axis, and the other end motion of screw axis is connected on the movable adjusting slider, adopts stepper motor and screw mandrel motion structure to realize accurate focusing automatically by control system control.
Described image sensor circuit plate links to each other with external control system by flexible PCB, make connecting line frivolous small and exquisite, be not easy to fracture.
Adopt the utility model scheme, rotating drive adjusting slider by external control system control step motor moves axially along guide pillar, the image sensor circuit plate can be moved with respect to the lens group that is installed in holder one end, promptly, realize the automatic focusing shooting by regulating the position of mobile image graph image-position sensor.The utility model scenario-frame is simple, installs easy to adjustly, has improved focusing accuracy.
Description of drawings now is further elaborated the utility model in conjunction with the accompanying drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment as shown in Figure 1, the utility model comprises lens group 1, holder 2, image sensor circuit plate 3, movable adjusting slider 4; The other end that one end of its holder 2 is equipped with lens group 1, holder 2 is provided with three guide pillars 21, movable adjusting slider 4 is enclosed within the guide pillar 21 of holder 2, and image sensor circuit plate 3 is installed on the movable adjusting slider 4; Stepper motor 5 is installed on the holder 2, and the front end of stepper motor 5 connects screw axis 6, and the other end motion of screw axis 6 is connected on the movable adjusting slider 4, and screw axis 6 can be selected STRTHD screw mandrel, trapezoidal screw or ball screw for use; Stepper motor 5, image sensor circuit plate 3 all pass through flexible PCB 7 and link to each other with external control system; Also being provided with three installation legs 22 on the holder 2 is installed in holder 2 on other equipment.Rotation by external control system control step motor 5 drives adjusting slider 4 and moves axially along guide pillar 21, image sensor circuit plate 3 can be moved with respect to the lens group 1 that is installed in holder 2 one ends, promptly, realize the automatic focusing shooting by regulating the position of moving image transmitting sensor circuit board 3.
