Micropore rapid detection method based on luminous flux and device

Abstract

The invention discloses a micropore rapid detection method based on luminous flux and a device; according to the method, a current measured value corresponding to luminous flux passing through a micropore to be measured is compared with a current standard value corresponding to luminous flux passing through a standard micropore to determine the quality of the micropore to be measured; high-efficient and accurate measurement of geometrical parameters of the micropore is realized, and actual demand for micropore rapid detection in the industrial field is effectively solved. The disadvantage is solved that when traditional micropore measurement is performed based on microscopic image technology, measurement results can not comprehensively reflect the geometrical morphologic characteristics of a long and thin micropore within an action length range due to the limitation of the depth of field of the optical system. The method and the device of the invention can effectively determine whether dirt or burr exists on the micropore inner wall, whether the micropore dimension is out of tolerance, whether the micropore is worn, and the like.

Description

technical field [0001] The present invention uses modern advanced optoelectronic technology to measure the geometric characteristics of microholes, and is specifically a method and device for rapid detection of microholes based on luminous flux. Background technique [0002] With the rapid development of industrial technology and modern science and technology, the level of mechanical manufacturing has been continuously improved and the development trend of miniaturization has appeared. Microporous devices are more and more widely used in machinery, instrumentation, aviation, electronics, biomedical and textile industries. . In the aviation industry, the small-thrust rocket engine injector diameter of the geosynchronous satellite attitude and orbit control is below 400 μm. The quality of the micro-holes in these micro-porous devices directly affects the performance of the whole machine. While the precision or ultra-precision machining of parts is proposed, higher requirement...
