郑巧装配流水线的PLC控制设计

1、郑巧装酉己流水线的PLC控制设计航空制造工程学院学科科技前沿题目：装配流水线设计班级学号：11031534学生姓名：钟理指导教师：高延峰二O 一四年六月 摘要本设计以当今自动化水平越来越高的现状。装配流水线 在生产过程中代替人力发挥出越来越重要的作用。以此为背 景从它的概念和特点出发，提出了装配流水线生产上的问题 和不足，如：生产不平衡、效率低、现场管理混乱等。各企 业经过调整装配作业指导、运用工序同期化和加强现场管理 等方法来改进这些问题。对装配生产流水线进行改进，最终 达到使整个装配线趋于平衡、装配效率有效提高和提高现场 管理的目的。PLC是现代通用的工业控制计算机。其接口容易，同时 PL

2、C的编程语言简单易懂很容易被不论是否有电路基础的用户 都能很快上手和掌握。在各个领域都得到广泛的应用，特别 是工业自动化领域。装配流水线是现在企业批量生产和扩大发展中不可或缺 的的生产方式。当前，PLC在装配流水线上应用广泛。而本设 计是在电脑上模拟控制整个装配流水线的流程，以现在较为 流行的PLC（可编程控制器）为基础来实现装配流水线的控制功 能。本次设计我以饮料装瓶为例。其程序是经过PLC控制8 盏LD灯的闪烁来模拟饮料装配流水线的传送、装瓶、盖盖、 贴签和成品入库。在程序设计中，我使用了大量的置位与复 位指令，并运用比较指令来选择不同的操作工位，结合传感 器使饮料瓶到达装配工位时停止传送

3、。经过多次的程序设计和模拟仿真，程序已能实现移位、三工位装配和单工位入库 等操作。关键词：装配流水线;关键词：装配流水线;PLC；控制系统AbstractNowadays, this design occupies important position in automation level.
