Abstract
Based on the requirements of automated product lines for marking on work pieces， an automatic marking system with computer control has been designed .Numatic marker is an important assistant tool widely used in the fields of auto，motor，achine and aero industry， and it can make products be effectively managed an didentified in manufacturing and utilization.At present，foreign pneumatic marker technology is more maturebut very expensive，while the domestic pneumatic marker system is not strong，easy to lose accuracy and operation inconvenience。Therefore，developing a pneumatic marker control system that is affordable，reliable and easy to operate has some theoretical significance and more ractical value.he marking device features agile character selection， compact volume， easy installation and excellent cost performance ratio.This study also shown the developing of a pneumatic marker with USB nterface based on Windows platform.These automatic markers have obtained good marking effect in productivity ,which have a broader perspective .

气动打标机的原理及打标系统的设计的研究
摘 要
为适应全自动生产线上对产品打标记的要求， 设计了一种可由计算机控制的自动打 标机。其中气动打标机是广泛应用于汽车、摩托车、机械、航空等领域中的重要辅助工 具，能够对产品的生产、使用等过程进行有效的管理和识别。目前，国外自动打标技术 较为成熟，但价格昂贵，国内气动打标系统抗干扰性不强，精度容易丢失，操作不便。 因此，研制一种经济适用、运行可靠、操作方便的气动打标机控制系统，该机具有选字 灵活、体积小、安装方便、性能价格比高等优点。既具有一定的理论意义，又具有较大 的实用价值。本文主要介绍了一套基于 USB 接口的气动打标机控制系统。这些自动打 标机在实际生产中都取得较好的良好的打标效果，拥有广阔的发展前景。
