Description
Technical field
The present invention relates to a kind of shutter.
Background technology
Shutter has just been invented multiple shutter in white light camera technology, from the lens cap shutter, and the plug-in strip shutter, center vane shutter between mirror, the tipping bucket shutter, focal plane shutter is to digital electronic shutter or the like.Only the electronic shutter of digital camera is not absorbing output place of photosensitive part, other all be the lighting quantity that controls to photosensitive part between at a time in the section with the shading mode, thereby the decision exposure value.Different with white light is, infrared shutter maximum effect is not the control exposure value, but assistant images is handled.Because the structural property of infrared eye own, its can be along with change of time, and image quality can variation, becomes fineless and smooth, and shelter from detector front with the consistent plane body of a temperature difference this moment, proofread and correct temperature difference processing after, image just can become original level again.This processing means of infrared eye are Nonuniformity Correction.Shutter is being taken on the important usefulness of doing in Nonuniformity Correction.
Even when current each bright red outer producer competition picture quality, perhaps the good job of shutter is determining last victory or defeat.So in the performance history of thermal infrared imager, producer pays much attention to the design and the production of shutter.Thermal infrared imager carries out timing, and general only need the closing of shutter blocked 0.3s, opens rapidly after electronic processing has been proofreaied and correct, and lets light again through aiming at focal plane, so just accomplishes once and proofreaies and correct.So shutter does not need very fast, takes into account cost, generally all be to be main with the guillotine type shutter.Because some application occasion; Like unattended district or automatic search system, during search or shutdown back thermal imaging system may be aimed at the sun, sunlight easy direct irradiation focal plane and fault localization device; Shutter prevents to burn out instrument in order to close shutter, so need have sunshade function, have two phasic properties.Existing shutter great majority all are single-phase; Promptly close the working method that the back relies on spring force to draw back; And mostly adopt the processing of independent metallic aluminium or steel disc, the processing back itself is prone to deformation, and the aluminium flake temperature that works long hours also can rise by straight line; Influence image rectification, spring also can lose efficacy along with long-time use.
Summary of the invention
The present invention is directed to the stable inadequately deficiency of prior art, a kind of simple in structure, cost is low, failure rate is low shutter is provided.
The technical scheme that the present invention solves the problems of the technologies described above is following: a kind of shutter comprises motor, motor cover, axle sleeve and shutter baffle;
Said motor one end is connected with the outside, and the other end is connected with axle sleeve, and said motor is located in the motor cover and power is provided for shutter baffle;
Said motor cover is set in the motor outside, is used to control the angle of the surface of contact of motor and camera;
Said axle sleeve one end is connected with motor, and the other end is connected with shutter baffle and carries out spacing to shutter baffle;
Said shutter baffle is fixedly set on the axle sleeve, and said shutter baffle comprises heat insulation layer and metal level, and said heat insulation layer is towards a side that is connected with motor, and said heat insulation layer is the isolated heat radiation of shutter baffle; Said metal level is used to dispel the heat reflective.
The invention has the beneficial effects as follows: simplified structure of the present invention, reduced volume reduces cost; Magnet manufacture the high high conformity of qualification rate, failure rate is low, bonding assembly technology is simple, volume is little; Shutter baffle back side plastics thermal insulation is good, and front metal dispels the heat reflective good, not with temperature variation, deformation does not take place, and is in light weight, and processing is simple, and the old shutter design that adds steel disc than spring will be optimized many.
On the basis of technique scheme, the present invention can also do following improvement.
Further, said motor cover inboard is provided with two fan-shaped locating slots, is separately installed with a magnet in said two grooves, and said magnet is used to limit axle sleeve and in the motor cover, rotates.
Further, said motor comprises motor shaft and motor main body, and said axle sleeve is fixedly connected with motor shaft.
Further, said heat insulation layer and metal laminate lump together and process shutter baffle.
Further, said heat insulation layer adopts plastics to process, and said metal level adopts thin silver film to process.
Description of drawings
Fig. 1 is the decomposition chart of the specific embodiment of the invention 1 described a kind of shutter;
Fig. 2 is the user mode figure of the specific embodiment of the invention 1 described a kind of shutter.
Embodiment
Below in conjunction with accompanying drawing principle of the present invention and characteristic are described, institute gives an actual example and only is used to explain the present invention, is not to be used to limit scope of the present invention.
As shown in Figure 1, the specific embodiment of the invention 1 described a kind of shutter comprises motor 4, motor cover 1, axle sleeve 5 and shutter baffle 3; Said motor 4 one ends are connected with the outside, and the other end is connected with axle sleeve 5, and said motor 4 is located in the motor cover 1 and for shutter baffle 3 power is provided; Said motor cover 1 is set in motor 4 outsides, is used to control the angle of motor 4 and the surface of contact of camera; Said axle sleeve 5 one ends are connected with motor 4, and the other end is connected with shutter baffle 3 and carries out spacing to shutter baffle 3; Said shutter baffle 3 is fixedly set on the axle sleeve 5, and said shutter baffle 3 comprises heat insulation layer and metal level, and said heat insulation layer is towards a side that is connected with motor 4, and said heat insulation layer is shutter baffle 3 isolated heat radiations; Said metal level is used to dispel the heat reflective.
