Design and Implementation of Color-changing Laser Marking Controlling System
TIAN Hui-feng (Department of Computer,Zhangjiagang Campus,Jiangsu University of Science and Technology,Zhangjiagang 215600,China) Abstract:The traditional laser marked controlling system adopts only two stepper motors to control two dimensional laser scanning mirror, thus it can only mark two colors, black and white, which could not print out colorful figures. This paper presents a new types of laser marking controlling system, that is, to control the rotation of grating by another servo motor while the two dimensional scanning mirror rotates so as to change the strip direction of interfering light point to mark different colors. Finally gives an experiment result to convince this technology, which is top ranking in the domestic color changing laser marking system field.
