Abstract
The utility model relates to an improved high precision positioning device for the focal planes of linear array CCD cameras, which comprises a pressing sheet, a CCD seat, a sloping spacer, a flat spacer, a pedestal, a CCD chip, screws and an adjusting rack. The utility model adopts mechanical adjustment that is combined with adhesive technology, so that the focal plane assembly of the CCD camera can achieve small size, light weight, simple structure, easy high precision adjustment, and high stability and reliability of the systems, which lowers manufacturing difficulty and cost, and emitting cost as well. The utility model can be used for the field of spaceflight and other focal plane adjusting mechanisms of various CCD cameras, and can also be used for thehigh precision adjustment of a plurality of CCD focal planes.
Description
The invention belongs to the optical instrument technical field, relate to a kind of improvement that CCD camera focal plane is realized high-precision positioner.
At present domestic on camera the mounting means of CCD focal plane mainly be the suspension structure that adopts the Titanium silk.Be characterized in the optimum position being adjusted in the CCD focal plane by adjusting the Titanium silk, make the titanium silk simultaneously in its elastic range, to keep image planes stable, but this system is structurally too complicated, for realizing that high-precision adjustment brings very big difficulty, stability and the reliability for total system impacts simultaneously.
The objective of the invention is to solve problems such as complex structure, precision and the reliability of adjusting the CCD focal plane low in the past, provide a kind of and debug simple in structurely, reduce weight simultaneously, reduce cost, improve the CCD focal plane of system stability and reliability and debug device.
The present invention as shown in Figure 1, include: compressing tablet 1, CCD seat 2, inclination pad 3, flat shim 4, pedestal 5, CCD chip 6, special spiral shell order 7, adjustment rack 8, CCD chip 6 places between compressing tablet 1 and the CCD seat 2, place inclination pad 3 and flat shim 4 between the end face of the bottom surface of CCD seat 2 and pedestal 5, after placing special screw 7 adjustment on the adjustment rack 8, be fastened on the pedestal 5 with screw, adjustment rack 8 by screw retention on pedestal 5.
Principle of work: at first, detection calibration facility by special high-accuracy, CCD chip 6 is installed on pedestal 5 reference planes, make the precision of the three degree of freedom of CCD chip 6 on this reference plane be guaranteed, by special screw 7 and adjustment rack 8, finish of the adjustment of CCD image planes again in two other degree of freedom.Simultaneously,, on optical axis direction, adopt mechanical fasteners, and in the personal module of image planes, inject RTV glue, guarantee image planes highly stable on each degree of freedom really for improving the stability of image planes.
For the adjustment configuration aspects of CCD on five degree of freedom.Can realize by following steps according to the concrete accuracy requirement of camera the CCD focal plane component:
A. by refine inclination pad 3 and flat shim 4, make the CCD assembly controlled on two different degree of freedom directions, so as to make its elsewhere three degree of freedom be in the same reference plane.
B. by adjusting the special screw 7 in the reference plane, make the CCD assembly on the direction of degree, obtain adjusting at three.
Good effect of the present invention: owing to adopted mechanical adjustment in conjunction with bonding technique, realized that camera focal plane component volume is little, in light weight, simple in structure, the high precision adjustment easily realizes, has improved the stability and the reliability of system.Reduce manufacture difficulty and cost, also reduced launch cost simultaneously.In addition, this technology also can be used for also can be used for the high precision adjustment of a plurality of CCD focal plane simultaneously in other various CCD camera focal plane adjusting mechanism except that space industry.
Most preferred embodiment: compressing tablet 1, CCD seat 2, inclination pad 3, flat shim 4, pedestal 5 adopt titanium alloy material to manufacture.CCD chip 6 is the outsourcing series of products, and metal materials such as special screw 7 and adjustment rack 8 usefulness A3 steel are made.
For improving stability of structure, in installation process, adopted the fastening means of pad and screw, solidified with RTV glue at last.For making its lightweight, after adjusting, install and demarcating end, the whole foldings of adjusting mechanism are fallen.Assembly, pedestal symmetrical structure have been adopted in shape in structure.
