摘要

通过利用PLC强大的控制功能,实现利用可编程控制器控制装配工序的功能,可以提高自动化行业的发展,提高劳动效率。本文针对PLC控制的自动装配系统,对系统的控制要求、设计步骤、控制方案、主要控制元件、编程思路进行深入的剖析。在PLC基础上,系统还增加了组态软件WINCC对系统运行过程进行监控,本文亦介绍了组态软件WINCC对控制系统的组态及运行方法。

通俗地讲,装配是指将产品的若干个零部件通过紧配、卡扣、螺纹连接、粘合、铆合、焊接等方式组合到一起得到符合预定的尺寸精度及功能的成品(半成品)。由人工处理(接触、整理、抓取、移动、放置、施力等)每一个零部件而实现的装配,严格的讲,只能称为人工装配。不需要由人工处理零部件而完成的装配,可称为自动装配。介于两者之间的为半自动装配。

当前,PLC因其强大的功能,被广泛应用于工业应用中,而随着管理信息系统和计算机集成制造系统的普及,生成现场数据的应用已不仅仅局限于数据采集和监控。在生产制造过程中,需要现场的大量数据进行流程分析和过程控制,以实现对生成流程的调整和优化。这就需要组态软件wincc来实现。本文针对PLC控制的自动装配系统,对系统的控制要求、设计步骤、控制方案、主要控制元件、编程思路进行深入的剖析。在PLC基础上,本文亦介绍了组态软件WINCC对控制系统的组态及运行方法。实验证明,通过利用PLC强大的控制功能,实现利用可编程控制器控制装配工序的功能,可以提高自动化行业的发展,提高劳动效率。关键词:可编程控制器, 自动装配, 控制系统

Abstract

Using the Powerful control function of PLC, realizing the function of controlling assembly processes by using the programmable controller, it can improve labor efficiency and the development of automation industry. Base on the automatic assembly system controlled by PLC, this paper gives a thorough analysis on the controlling requirement of the system, the design procedure, the control scheme, the main control components and the programming ideas. In base on PLC, the system also increase the configuration software for system operation process WINCC monitoring, this paper also introduces the configuration software WINCC of control system configuration and operation method.

Generally speaking, assembly refers to get the several parts of the product together with combination with accuracy and functionality in line with a predetermined size of the finished(semi) by tight with clasps,threaded connection,bonding,riveting,welding,ect. Assembly by manual processing (contact, organize, capture, motion, position, force, etc.) of each component, strictly speaking, only be described as manual assembly.The assembly which do not need to complete the assembly of the parts of the manual processing can be referred to as automated assembly. In between is semi-automatic assembly.

At present,because of PLC’s powerful features,it is widely used in industrial applications,along with the popularity of the management information systems and computer integrated manufacturing systems,the application of generated field data is not limited to data collection and monitoring. In the manufacturing process,we need the scene of large amounts of data flow analysis and process control,in order to achieve the adjustment and optimization of the generation.this requires the configuration software WinCC to achieve.Base on the automatic assembly system controlled by PLC, this paper gives a thorough analysis on the
