Horizontal image online meter

Abstract

The invention discloses a horizontal image online meter, belongs to the field of measuring instruments and is used for metering and detecting workpiece products. The horizontal image online meter comprises a charge couple device (CCD) camera, a zoom lens, image components of a surface light source and a transmission light source, a computer system and a workbench, wherein the CCD camera, the zoom lens and the surface light source are assembled integrally and the CCD camera, the zoom lens and the surface light source and the transmission light source are arranged opposite on the front and rear sides of the workbench; the transmission light source is arranged on an upright bracket which can deflect at a certain angle around a Y-axis; the image components and the workbench form a horizontal measuring platform for measuring the end face of a large workpiece or a long workpiece; and an object stage of the workbench can deflect at a certain angle around a Z-axis and can be used for performing multi-angle measurement, so that measuring precision is improved.

Description

technical field [0001] The invention relates to the technical field of measuring instruments, in particular to a horizontal image on-line instrument. Background technique [0002] In the field of measurement, the image measuring instrument is widely used in colleges, research and development institutions, measurement rooms and other places because it uses optical contrast to generate image data and is assisted by computer analysis. Parts are measured with high precision. The traditional image measuring instrument is a vertical structure, that is, the lens shoots and scans the object from top to bottom, and the shooting distance is adjusted by lifting the instrument. It is very important for teaching, research and development, and small batch testing. It can meet the measurement requirements; however, as the requirements for industrial production automation become higher and higher, image measuring instruments for precision measurement will be more and more widely used in ind...

[0002] In the field of measurement, the image measuring instrument is widely used in colleges, research and development institutions, measurement rooms and other places because it uses optical contrast to generate image data and is assisted by computer analysis. Parts are measured with high precision. The traditional image measuring instrument is a vertical structure, that is, the lens shoots and scans the object from top to bottom, and the shooting distance is adjusted by lifting the instrument. It is very important for teaching, research and development, and small batch testing. It can meet the measurement requirements; however, as the requirements for industrial production automation become higher and higher, image measuring instruments for precision measurement will be more and more widely used in industrial fields such as machinery, molds, instruments, electronics, and light industry. Introduced into fully automatic streamlined production operations, it is no longer only used for the measurement of small and complex precision components, but also involves the measurement and even verification of large workpieces. The limitations of traditional image measuring instruments have become very obvious. One On the one hand, the vertical image measuring instrument has a small loading space and cannot measure the end face of large-volume workpieces or long workpieces. On the other hand, the measurement accuracy and automation of traditional image measuring instruments cannot fully meet the requirements of automated production.
