Study on process of marking two-dimensional codes on air circuit breakers by UV laser
摘要
Abstract
The quality of two-dimensional codes on air circuit breakers depends on laser parameters such as scanning speed, Q frequency, line spacing, electric current and defocusing distance. The experiment changed laser parameters according to the orthogonal table L16(4S). Color difference was measured by a spectrophotometer and code success ratio was tested by a bar code scanner. Orthogonal analysis and range analysis were carried out to study the influence of laser parameters on marking effect. The experiment shows that, there is a threshold color difference and the linear relationship between color difference and code success ratio is good. Perfect two-dimensional codes are obtained with optimum laser parameters, which are 1 000 mm/s scanning speed, 20-30 kHz Q frequency, 0.04 mm line spacing, 28 A electric current and -1 mm defocusing distance.关键词
