Abstract

The invention provides a detection and recognition device for sprayed codes on the cylindrical surfaces of copper rings. The detection and recognition device comprises an industrial display screen, a left conveying belt mechanism, a servo sliding table mechanism, a right conveying belt mechanism, an industrial computer, an article grasping clamping air cylinder, an image collecting mechanism, light source equipment, a rejected product receiving box, a qualified product receiving box, a removing mechanism and a rotating mechanism. According to the detection and recognition device for sprayed codes on the cylindrical surfaces of copper rings, the machine vision technology is adopted to detect and recognize sprayed code character information on the cylindrical surfaces of copper rings, and the defects of low precision, high subjectivity, low judgment efficiency, high missed detection rate and false detection rate and the like of traditional manual detection are overcome; the automation degree is high, and automatic recognition and automatic sorting of sprayed codes on the cylindrical surfaces of copper rings can be completed. The invention further provides a detection and recognition method for sprayed codes on the cylindrical surfaces of copper rings. By means of the detection and recognition method, irregular sprayed code information on the cylindrical surfaces of copper rings on a production line can be continuously and automatically collected and distinguished, and the detection and recognition method is especially suitable for handling recognition of fuzzy and irregularly-shaped characters on the cylindrical surfaces and is high in detection and recognition rate.

Description

technical field [0001] The invention belongs to the technical field of detection equipment, and in particular relates to a coding detection and recognition device and method for a cylindrical surface of a copper ring. Background technique [0002] In industrial production, a lot of product-related information is recorded on many products, such as product quality accuracy, batch number, production place, manufacturer, etc. Some of this information is directly engraved on the product surface by die-casting or printing inkjet code It turns out that different products, different technological processes and manufacturing will result in different printed text information, so the identification methods adopted are also different, such as QR code scanning, bar code scanning, character recognition, etc. [0003] At present, the detection of coded character information of copper ring manufacturers is realized by manual observation and independent judgment. The labor cost is high and t...
