【摘要】 激光打标机是集激光、光学、机械、电子和计算机等技术于一体的机电一体化设备。它利用高能量密度的激光束在物件表面制作永久性标记。已经在很多领域取代传统的打标方式而成为常规的加工方式，甚至形成新的工业标准。 目前在线激光打标有着很大的市场前景，国内外激光打标行业在此领域竞争十分激烈。当前在中低速激光打标领域国内激光打标行业和国外同行业不相上下，而速度高于250字／s的高速激光打标领域一直被国外所垄断，国外采用的阵列式在线激光打标机标记速度最高可达2000字／秒，能够满足速度为7m／s以上的生产线的打标需要。为了打破高速激光在线打标机市场被国外垄断的局面，我们在河南省高校杰出人才创新工程“高速在线CO₂激光打标机”项目经费的支持下，开始研制我们自己的具有自主知识产权的阵列式在线激光打标机。 本文对阵列式在线激光打标系统的研制过程进行了全面的讨论，着重介绍了打标机系统的整体设计以及字符采集模块和输出模块具体实现。主要内容如下： 1、分析了国内外激光加工业特别是激光打标机及其市场现状、发展趋势和市场前景。 2、对阵列式激光打标机系统进行了整体设计。 （1） 控制系统的设计 （2） 集成化光路传输耦合系统的设计 3、针对阵列式激光打标机采用字符的点阵信息打标的特点，开发从矢量字库提取字符的点阵信息的软件系统。实现了对不同字体、字号打标字符点阵信息的提取。 4、解决了WINDOWS下微秒级的精确定时问题，实现了用微机通过软件对激光器阵列的精确调制。保证了阵列式在线激光打标机输出稳定的高频率激光脉冲。更多还原

【Abstract】 Laser marker is an electromechanical integrating equipment referring to laser, optics, mechanism, electricity, and computer, which makes permanent mark on the surface of the workpiece by high-density laser beam. Now it has been widely used in many fields of industry. Moreover, laser marking is required by the new industry standard.At present, on-line laser marking has the best prospect in the laser marking market and the rivalry between the domestic and the foreign is drastic in the laser marking business. For the moment, the domestic is all square with the foreign in the middle and low velocity laser marking field, but the high velocity field that the velocity is higher than 250 character per second is monopolized by the foreign . Now arrayed laser marker, the new product of the foreign , can mark 2000 character per second, which can satisfy the user whose velocity of the product line is higher than 7 meters per second. In order to break the situation that the foreign controls the high velocity field, we begin to research our own high-velocity laser marker under the support of the outlay of "Innovation Project of the outstanding talents in High Academy in Henan Province" .This article discusses the whole process of the research of the arrayed on-line laser marker. It mainly introduces the design of the whole system , the realization of the character collection module and the output module. The summary of this article is as follows:l.The development of laser industry , the prospect and technically advantages of laser marking are reviewed.2. The design of the whole system of the arrayed on-line laser maker.(l)The design of the control system .(2)The design of the integrating optical transport and coupling system.3. The software was designed used to gain the lattice information of any character from the Windows vector fontbase.4. Realized the high-precision timing up to 122 microsecond and realized the accurate control to the laser array, ensure the laser marker to output the steady-going high frequency impulses.更多还原
