Study on laser flying marking systems based on DSP and CPLD

In order to achieve fast and high precision,a dynamic laser flying marking system equipped on product line was introduced based on digital signal processing(DSP) and complex programmable logic device(CPLD)'s dynamic tracing technology so that the problems in the course of laser process on product line,such as metamorphosis,dislocation,distortion was solved,and the labor degree of workers was decreased than the static marking system.Applying the software developed by ourselves,with the laser parameters'setting marking on the same object,it can be seen that the efficiency of laser marking was enhanced with a velocity up to 2000byte/s and the marking line and silhouette were very clear.To the same marking result was achieved on both the dynamic and the static marking systems.
