Embodiment Construction

[0020] When observing the flatness of the measured workpiece, install the measured workpiece 10 on the horizontal device, place the standard sample 8 on the top of the measured workpiece, and separate it with a thin paper sheet 9 so that there is an appropriate air angle between the two. ; Turn on the laser light source system 1 to make it emit a laser beam. The laser beam is shaped into collimated parallel light through the diaphragm and the convex lens, and the adjustment device makes the beam shaping reach the best state; The light reflected from the upper and lower surfaces of the air wedge formed by the measured workpiece and the standard workpiece forms interference fringes; the interference fringes are reflected by the semi-mirror and irradiated on the CCD; the sensing system is turned on, and the change of the interference light intensity is collected by the CCD, and then passed through the computer. displayed, so that the flatness of the measured workpiece can be visua...

Abstract

The invention provides a detection system and a method for detecting scraper planeness by using a wedge interfere principle. The scraper planeness detection system comprises a light source (laser) system, a beam shaping system and a sensing system, wherein the light source system is a monochrome He-Ne laser, the beam shaping system is composed of an aperture and a half transparent and half reflecting mirror, and the sensing system consists of a standard template and a CCD detection device. The detection system can detect the planeness of the scraper working surface in a rapid, accurate and non-wear manner.

Description

technical field [0001] The invention relates to a system and a method for detecting the flatness of a working surface of a scraper in a toner cartridge for a printer. Background technique [0002] The flatness of the working surface of the squeegee is an important factor to measure the quality of the squeegee. The poor flatness of the working surface of the squeegee seriously affects the printing quality, so it is necessary to accurately detect the flatness of the working surface of the squeegee. The existing methods for measuring the flatness of the working surface of the scraper generally use a magnifying glass to observe with human eyes. This measurement method has a large error and a slow detection speed. At the same time, the scraper needs to be moved continuously during detection, which may easily cause wear on the working surface of the scraper. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides an accura...
