Study on laser flying marking systems based on DSP and CPLD

为了达到快速、精确标刻的目的,提出了一种应用于生产线上运动工件的激光实时飞动标刻系统。该系统采用了数字信号处理和复杂可编程逻辑器件的动态跟踪技术的方法,解决了流水生产线上诸如标刻图形变形、错位、失真等激光加工问题,降低了由静止标刻加工给加工者所带来的劳动强度。以自行开发的激光标刻软件为应用实例,对同一图案在参数设定相同的情况下进行加工。结果表明,该系统能提高激光加工的生产效率,标刻速度达到2000byte/s;所标刻图案线条清晰,轮廓分明,达到了静止标刻的效果。

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.
