Description
Technical field
Instrument surveyed in a kind of accent that the utility model relates in the scanner process for making, is specifically related to a kind of adjustment instrument of scanner lens focal length.
Background technology
In scanner, camera lens is the vitals of optical scanning device for image, and its optical effect quality is not only relevant with the quality and the performance of camera lens itself, and relevant with technologies such as assembling, accent surveys.Say to a certain extent, not only the adjustment of lens focus is indispensable in the scanner assembling process, and seems quite important, because the most direct effect of this adjustment is the high optical property of performance camera lens.
In the prior art, scanner head mainly is made up of bare headed frame, camera lens and CCD/B photoelectrical coupler etc., and camera lens is inserted in the camera aperture of bare headed frame during assembling, and the CCD/B photoelectrical coupler is installed on the lens imaging position, thereby constitutes scanhead unit.After the scanhead unit assembling is finished, need its mtf value to be detected, adjust the accent survey ring (or draw-in groove) that then adopts circular camera lens accent to survey on the direct effect of the rod camera lens outer rim if desired and adjust with OMA-optical facilities adjustment utensil.Transferring and surveying rod is that a kind of clavate camera lens mtf value is adjusted instrument, its head is provided with an eccentric lobe structure, and projection stretches in the accent survey ring of camera lens during adjustment, rotates barred body then, projection moves forward and backward along camera aperture by transferring the survey ring to stir camera lens, thereby adjusts lens focus.Though it is simple in structure that rod surveyed in existing accent, but the shortcoming that exists is: when 1, adjusting MTF because of the point of application not in the optical center, and acting force produces component on the direction of Vertical camera lens center line, the result causes the camera lens deflection easily, be unfavorable for the adjustment of MTF, 2, adopt the amount of feeding that camera lens advances, retreats when transferring the survey rod to adjust accurately to control, phenomenon more or less often appears, especially to the optical device of this class precision of lens focus, it is very accurate that focal length requires, such adjustment instrument obviously is inappropriate for producing in batches.For this reason, the utility model has designed a kind of effectively regulating and controlling amount of feeding from the angle of policy adjustment instrument, avoids the camera lens deflection, and OMA operation camera lens adjustment easily instrument, to overcome above-mentioned deficiency.
Summary of the invention
For achieving the above object, the technical solution adopted in the utility model is: a kind of scanner lens focal length is adjusted instrument, comprise pedestal, slide block, spring, adjusting screw(rod) and inclined-plane, pedestal is provided with the supporting structure that is connected with bare headed frame or OMA frame, the two ends of slide block are connected by slide mechanism with pedestal, the slide mechanism front portion is provided with spring, spring action is between slide block and pedestal, stretch out a pair of camera lens that snaps on the slide block downwards and transfer the jaw of surveying ring, adjusting screw(rod) is threaded with pedestal from side direction, its top by ramp effect on slide block.
Related content in the technique scheme is explained as follows:
1, described " bare headed frame " is meant the scanner head skeleton that camera lens is installed, and also claims the scanner head monomer.Described " OMA frame " is meant that being specifically designed to a kind of optical facilities of adjusting the scanner lens mtf value adjusts the utensil frame structure.Described " supporting structure " is to point to pedestal fixed supported syndeton is provided, because this instrument needs supporting-point when the effect camera lens, provides supporting by being connected with bare headed frame or OMA frame positioning and fixing generally speaking.Described " jaw " is a kind of structure that camera lens transfer to be surveyed ring that directly acts on, and keeps balance in order to make acting force, and general jaw is the sheet clamp structure, and jaw is inserted in the camera lens outer rim ring groove during work, and two over against locating simultaneously effect forward or backward.
2, in the technique scheme, described " adjusting screw(rod) is threaded with pedestal from side direction, its top by ramp effect on slide block " has following three kinds of concrete conditions:
(1), the slide block rear portion is provided with the inclined-plane, is provided with wedge between this inclined-plane and the pedestal, adjusting screw(rod) acts on wedge from side direction.
(2), the slide block rear portion be provided with the projection application point, application point to and pedestal between be provided with wedge, adjusting screw(rod) acts on wedge from side direction.
(3), the slide block rear portion is provided with the inclined-plane, adjusting screw(rod) directly acts on the inclined-plane from side direction.
What described wedge was commonly used is corner block, and wedge also can adopt other shape certainly, but its condition is that the pitch angle must be arranged, and also the effect at this pitch angle just makes wedge shoe member have work efficiency at work just.In order to reduce the amount of feeding, no matter the inclined-plane still is its hypotenuse of wedge can be designed to 2:1 with the adjacent side ratio, even bigger, and effect is better like this.
3, in the technique scheme, the outer end of the more laborsaving adjusting screw(rod) of turn can be provided with vernier adjustment knob when regulating in order to make, and vernier adjustment knob is fixedlyed connected with adjusting screw(rod).The outer rim of vernier adjustment knob can adopt annular knurl to handle.
4, in the technique scheme, the supporting structure that is connected with bare headed frame on the pedestal can be two angles, and the shape of two angles and size cooperate with the bare headed frame cavity that camera lens is adjusted the position, and the side of angle is provided with the elastic steel ball bulge-structure.
5, in the technique scheme, pedestal is overlooked and is that U-shaped structure, slide block are located at during the U-shaped structure dehisces, and its two ends adopt the chute structure to be connected with U-shaped structure both sides respectively.
6, in the technique scheme,, be provided with roller or steel ball between the inclined-plane of slide block and the inclined-plane of wedge in order to reduce the friction between two inclined-planes.
The utility model principle of work is: during use, utilize pedestal upper support structure that this instrument is fixed on earlier on bare headed frame or the OMA frame, the bipod with jaw is stuck in the camera lens accent survey ring simultaneously; During adjustment, utilize the screw mechanism adjusting screw(rod) that turns clockwise, the front end of screw rod by ramp effect in being fixed on the slide block upper gripper jaw, thereby camera lens is moved forward; When retreating, be rotated counterclockwise adjusting screw(rod) simultaneously, utilizing the spring thrust between slide block and pedestal slip front portion that camera lens is moved backward.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
Forward and backward mobile amount of feeding when 1, the utility model can controls lens be adjusted, two draw-in groove structures can avoid the camera lens lateral force to cause deflection, thus the MTF numerical value accurately during rapid adjustment camera lens OMA operation makes MTF numerical value reach optimum condition.
2, the utility model adopts the inclined-plane to carry out switch transition and finally acts on jaw on the screw mechanism basis, and wherein the effect on inclined-plane can reduce the amount of feeding on the one hand, on the other hand the more reasonable stress of slide block.
3, the utility model is designed to two angles with supporting structure, the shape of two angles and size cooperate with the bare headed frame cavity that camera lens is adjusted the position, the side of angle is provided with the elastic steel ball bulge-structure, can carry out the quick plug-in location in order to bare headed frame upper cavity shape like this, the MTF that has improved scanner head greatly adjusts work efficiency.
