intro
Label printers are a kind ofCarbon tape heat transferMeans of, A device that continuously prints the entire volume of labels, The carbon belt belongs to consumables. The principle of carbon tape heat transfer is determined, If the carbon belt quality problem, Or print head wear and other reasons, May cause label printing quality problems.
Traditional detection idea: Area array camera (Intelligent area array camera) , Linear array camera, Code reader. The disadvantages of these methods are also obvious. Such as,
Limited field of view, Not compatible with long labels (Area array) ;
Need to design a larger camera platform (Area array) ;
Read only, Print quality cannot be detected (Code reader) ;
A winding mechanism is required, The label is kept flat by winding tension;
Light source required, But the lights are blinding, Not a good place to work together;
Occupy a large space, Not suitable for compact desktop environments;
The online error detection systemIt is designed for all kinds of label printersLabel detection system.
Print while detecting, With printer "Blend together" ;
It is a kind of "Machine vision algorithm" As the core of the hardware and software combined comprehensive detection system;
Substituted labor, Detect label print quality defects, OCR recognize, Bar code readability;
100%Check the print quality of the label.
