1、 摘要玻璃清洗机是玻璃生产中必不可少的设备，清洗大面积曲面玻璃是目前玻璃清洗技术的难题。本文所述的研究工作，是对清洗大面积曲面玻璃的清洗机电气控制系统进行设计。目的在于通过电气控制系统设计，实现大面积曲面玻璃自动或手动完成清洗、吹干、旋转等工作过程的自动控制，并能通过人机界面动态显示现场数据，实现操作人员对设备的控制。 本文的主要工作包括以下几方面: 首先，介绍玻璃清洗机的组成和结构，分析清洗机的工作过程，从而制定各工作过程的控制要求。 其次，根据上述控制要求，设计清洗机电气控制系统总体方案。包括电气控制系统原理图设计、驱动系统和检测系统设计、PLC与人机界面的连接、交流调速系统的设计等。 再
2、次，进行了电气控制系统的硬件设计和软件设计。硬件设计主要包括主要电气元件的计算和选型、变频器的选型和参数设计、软启动器的选型、PLC的选型、触摸屏的选型等。软件设计主要包括PLC的程序结构设计和触摸屏软件设计。 最后，进行了电气系统的安装和调试。通过电气控制系统的调试和运行，验证了本文所设计的电气控制系统能满足清洗机的工作要求。 本文采用PLC完成数据采集和生产工艺过程的控制，采用触摸屏实现监控，达到了让玻璃清洗机按照生产工艺要求清洗大曲面玻璃的目的，提高了玻璃清洗质量和生产效率，降低了能耗。实际运行表明，所设计的系统具有自动化程度高、可靠性高和人机交互友好等特点。关键词:清洗机，电气控制系统
3、，PLC，触摸屏 Abstract The glasses cleaning machine is necessary equipment in glasses production.Washing large一area glasses with curved face is one of the unresolved problems in thecurrent glasses一cleaning technologies. This research work is the design on electricalcontrol system of the glasses cleaning
4、machine which washes large一area glasses withcurved face. The purpose of the design is to realize the automatic and manual processcontrols of cleaning, blow一drying and rotating, display measured data real-timely andcontrol the equipment by means of HMI (Human Machine Interface).The mainresearch works
5、 of this paper are as follows: First, the components and configuration of the glasses cleaning machine wereintroduced. The work processes of the machine were analyzed. The controlrequirements for those processes were decided. Secondly, the general project of electrical control system of the machine
6、wasdesigned according to the requirements mentioned above. It include the design ofelectrical principle scheme, the design of driving and measuring systems, connectionsbetween PLC and HMI, and the design of AC timing system etc. Thirdly, the hardware and software of the electrical control system wer
7、edesigned. The hardware design mainly include the calculation and selection ofelectrical components, the selection and parameter design of frequency changer, andthe selection of soft一starter, PLC and touch screen.
