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.
