基于PLC的全自动浸渗设备控制系统设计

Control System Design for Automatic Impregnation Equipment Based on PLC

摘要: 汽车制造行业中，铸造件在铸造过程中容易产生内部微孔、细缝、气隙等缺陷，这些缺陷的存在将导致气密性测试过程中密封介质的渗漏，造成测试结果不稳定甚至泄漏量不合格等后果。本文介绍了一种全自动浸渗修补设备，详细描述了系统各部分组成及功能、操作工艺流程及软件设计思想、人机交互界面等内容，能够实现智能浸渗服务，具有较高的安全性、可靠性、精确性、可操作性、高效性等特点。

Abstract: In the automotive industry, defects such as internal micro-pore and air gaps will be produced during the process of casting. These defects will cause the leakage of sealing medium during air tightness test, which will lead to the instability of test result or even NG (no good) result. An automatic infiltration repair equipment will be introduced in this paper, which in detail describes hardware components and functions, operation process and software design flow charts, and HMI (Human-Machine Interface) contents. Intelligent infiltration service will be realized through using this equipment, which has higher security, reliability, accuracy, maneuverability, and efficiency.
