2、acture and AutomationOrientation: The production line automationHarbin ChinaMay 2016摘要随着科技的进步发展、生产力的不断提高，手工装配生产线已经满足不了市场的需 求，PLC的出现使工业自动化成为了可能，自动化生产线提高了生产效率，减轻了人的 工作负担。自动化生产线支持技术的不断发展，使得自动化程度提高，能够满足生产装 配中更高的工艺要求。本文根据生产线的设计原则，设计了发动机缸盖组装检查生产线的总体工艺布置设 计。根据生产中的实际情况设计生产线，使得发动机缸盖装配生产线占用生产面积最小生产线的布置使装配、检测效

3、率最高，成为经得住推敲的最优化方案设计。生产线采用三菱 PLC-FX2N -64MR机控制，同时根据发动机缸盖装配、检查生产线的各个工位的工艺要要求、按照生产节拍每件 60秒设计PLC控制系统。编程所用软件为GX Developer，编程方法为步进梯形图编写。步进梯形图编写使程序逻辑控制简化、 程序简单易懂、易于更改、程序设计简单、对于初学者更易上手。本设计中涉及到的工 艺要求较为复杂，所以采用步进梯形图。在本文设计的PLC控制系统中的驱动功能是气缸、电动机、机械手执行机构，通过这些执行部件来实现各个工位的工艺要求。关键词：生产线；自动化；PLC;梯形图Overall Process Of A
