A kind of coaxiality adjustment structure of ccd camera

Abstract

The invention provides a coaxiality adjusting structure of a CCD (Charge Coupled Device) camera, comprising a cylindrical dark box, wherein upper and lower ends of a box body are opening ends; upper and lower box covers are respectively configured at the two ends of the box body; a hole is formed in the center of the bottom of the lower box cover; a reaction plate is located rightly below the hole; a plate-shaped CCD fixing frame is distributed below the upper box cover and a hole is formed in the center of the upper box cover; a CCD piece is embedded in the hole; the lower end of the CCD piece is arranged towards the center of the reaction plate; a step vertically and downwards protrudes from a cover plate of the upper box cover; vertical unthreaded holes are formed in the step; a threaded hole is formed in a corresponding position of an annular plate edge of the CCD fixing frame; adjusting bolts are downwards inserted into each pair of the unthreaded holes and the threaded hole from the upper side of the upper box cover; and the CCD fixing frame is fixedly arranged on the upper cover box. According to the structure disclosed by the invention, the upper box cover does not need to be opened and the coaxiality of the CCD piece and the reaction plate can be finely adjusted, so that the operation is convenient and the time is saved; and the adjustment can be directly and conveniently conducted and the best image imaging effect can be obtained.

Description

technical field [0001] The invention relates to the field of CCD cameras, in particular to a structure for adjusting the coaxiality of a CCD and an object to be photographed. Background technique [0002] CCD is the abbreviation of Charge Coupled Device (Charge Coupled Device). It is a semiconductor imaging device, so it has the advantages of high sensitivity, anti-glare, small distortion, small size, long life, and anti-vibration. When the CCD camera is working, the image of the subject is focused on the CCD chip through the lens, and the CCD accumulates a corresponding proportion of charge according to the intensity of the light, and the charge accumulated by each pixel moves outward point by point under the control of the video sequence. , after filtering and amplification processing, a video signal output is formed. Connect the video signal to the video input of a monitor or TV, and you can see the same video image as the original image. [0003] In a commonly used CCD...

Problems solved by technology

During the adjustment process, it is impossible to determine whether the adjustment bolts correspond to each other and whether the adjustment amount of the bolts is appropriate. It often takes more than ten or even dozens of times to repeatedly remove the upper box cover, adjust the tightness of the bolts, and install the upper box cover for observation. The set of actions of coaxiality is not only cumbersome and inefficient, but often the final adjustment result cannot guarantee the best graphic imaging effect
