摘要
在全面了解了国内外多针头打标机的应用现状、发展趋势及存在问题的基础上,
详细介绍了打标机的工作原理,并根据用户对现有打标机的改革期望,采用 32 位
单片机实现扩展功能,使整套系统具有激光测距、控制电机高速运动、快速标记等
功能,以满足用户需要。根据步进电机启动原理及指数形升降速曲线,设计了一种
便于实现的“台阶式”指数形升降曲线。该算法扩展性强且使用简单,将老系统中
用气阀控制打标头伸缩的方式改换成用步进电机带动打标头快速移动的方式,不仅
在速度上有较大提升,而且更有利于钢厂生产线装配。采用多针头标记算法进行标
记,相比于传统单针头标记效率更高,在用户最为关心的标记速度上达到了要求,
为缩短整条钢板生产流水线运作时间作出了贡献。
本文对七针头气动打标机的硬件架构和软件系统分别作了详细介绍,在控制板
和扩展板的制作和调试方面有丰富的实践体会,曾赴江西等地参与设备的安装和调
试。所研究的多针头打标机,多项指标达到了速度、打标
深度等均已向国家科技部门申请了成果,且已送往钢板厂正式使用。所研究的多针
头标记算法不仅适用于单排针头标记,还可以推广到多排针头标记。论文所做工作
对标记行业产品更新具有重要参考价值,对其他工业自动化产品的升级也具有推广
意义。

Abstract
.Based on prehensive understanding of the domestic and overseas
multi-needle marker of the status quo and development trends and problems, this paper
describes the principle of marker, according to the existing mark expectation of users, the
system used 32 MCU for expansion functions. It makes the whole system has a laser
rangefinder, high-speed motor control, quick markers, and other functions to meet the
user needs. Under the principle of step motor start and the index-down curve, the author
designed achievement of a "ladder" index-shaped curve movements which is easy to
realize. The arithmetic has a good expansibility and is simple to be used, it change the
way of controlling of an, the old system used telescopic valve to control the
an and the new system used step motor to control the an, it not
only took a greater speed upgrade to the new system, but also took advantages to the
production line of assembly for steel factory. It is more efficient by using multiple
needles marking pared with the traditional single-needle marking, and it
achieves the request of marking time which the users most care about, and contributes to
shorten the operating time of the entire production lines.
