An image detector that can be cleaned quickly without damaging the measurement plane

Abstract

The invention discloses an image detector that can be quickly cleaned without damaging the measurement plane. Its structure includes a detection seat, a lens adjustment handwheel, a detection lens, a measurement plane cleaning device, a panel moving handwheel, a base, a slide rail panel assembly, and a workpiece The placement plate and the glass measurement plane are welded and fixed on the back of the base. Compared with the prior art, the cleaning box is moved to the left by dragging the drag bar. The wavy route allows the moving wheel to drive the supporting column to move left and right, and the elastic cleaning strip moves with it by means of the limiting block. The elastic cleaning strip can slide up and down in stages and rub against the glass measuring plane to clean up oil and dust while moving forward. , improve the cleaning efficiency, and at the same time avoid the phenomenon that manual cleaning is easy to cause accidental scratches on the measurement plane, reducing the probability of scratches on the measurement plane and causing errors in workpiece measurement.

Description

technical field [0001] The invention belongs to the technical field of image instruments, and in particular relates to an image detector that can be quickly cleaned without damaging a measurement plane. Background technique [0002] The imager is a high-precision measuring instrument that relies on computer screen measurement technology and powerful spatial geometry calculation software. After being illuminated by surface light or contour light, the image is captured by the zoom objective lens through the camera lens and then transmitted through the S terminal. to the computer screen, and then use the crosshair generator, the video crosshair generated on the display as a reference, to target and measure the measured object, but the lack of consideration in the prior art is: [0003] The imager has high requirements on the working environment. If there are scratches, oil stains or dust on the flat glass measuring surface, the imager will be inaccurate in measuring the workpie...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an image detector that does not damage the measuring plane and can be cleaned quickly, so as to solve the problem that the imager has high requirements on the working environment. Oil or dust will make the imager's measurement of the workpiece inaccurate, and the measured parts will inevitably have a little oil. After measuring these parts, the oil will remain on the flat glass measuring surface and absorb the dust in the air. Such small particles make it impossible for the next workpiece to stick to the plane, resulting in a large measurement error, which means that the plane glass measurement surface needs to be cleaned from time to time. It is easy to scratch the measuring surface of the flat glass, and the scratches will refract the contour light, so that the image obtained in the subsequent use will be deviated, and the gain outweighs the gain
