Description

Cylindrical glass stick vision inspection apparatus

Technical field

The utility model relates to cylindrical component testing equipment fields, and in particular to a kind of cylindrical glass stick vision-based detection dress It sets.

Background technique

Many kinds of, the small glass bar to stirring of daily middle cylindrical component, arrives automobile shafts etc. greatly, is all in cylinder Shape.Camshaft, crankshaft especially in automobile etc., are all particularly important components, and geometric tolerance and overall size are shadows The principal element of automotive performance is rung, therefore is typically necessary after manufacture and the cylindricity of cylindrical component is detected.

Cylindricity measurement is the measurement in length metering technology to cylindricity error.When measurement, the gauge head of linear transducer Several cross sections that tested cylindrical body is measured along precise linear guide, can also be along measured cylinder surface sampling for the helical movement.In recent years Come, cylindricity can also be detected by several industrial cameras.

With the rapid development of machine vision imaging sensor, industrial camera is divided into line-scan digital camera substantially from scanning theory And area array cameras, and scanning speed is higher and higher, and line-scan digital camera is up to 120Kline/s, and area array cameras acquisition speed also reaches 500FPS (refresh rate).In current detection application, line-scan digital camera is mainly used for printing checking, planar disfigurement detection；Face battle array Camera is detected for overall size, and image procossing compares, the demands such as positioning.
