Environment-protection vacuum electrostatic coating technology have gradually developed, which combining of vacuum and electrostatic action principle. While technology was applied to the actual equipment manufacturing, the researches of important subsystem have taken much progress. As a way of communication between the vacuum chamber and the external environment, pipeline system, affects the equipment efficiency and product quality at a great extent. Simplified and efficient system provides reliable air supply and exhaust for production of coating equipment. Structure design of pipeline system, automation control and parameter combination is the keys to the overall development.This paper mainly researches and designs the pipe system of environment-protection vacuum electrostatic coating equipment, including the construction and optimization of system analysis, system automation control and advantage parameter design of the combination system. Based on the research of the former pipe system, a new system has been designed to meet the equipment requirements and provide reference for subsequent development. This subject comes from Guangdong province production project "high efficiency and energy-saving environment-protection vacuum coating technology research". This paper mainly completed the following works:First of all, the air inlet system and extraction system in pipe system has been researched and designed. Analysis about pipe system requirements has been done. And modularization design idea is putted forward to pipeline system in view of the series vacuum coating equipment. Rapid design and combination of pipe system was achieved when using different equipments. That system model and pipeline feasibility as well as internal medium flow can be analyzed according to the equipment parameters and the external environment. Analysis results show that the structure of the system can meet the design requirements. And it shows that this way of design is feasible.Secondly, pipeline system automation control system has been designed. According to the automatic control equipment, control system is designed for pipeline system with the combination of sensors, PLC, touch screen. In order to make the operation of the system have independent ability, the PLC control program and touch screen is edited. The system can operate combined with equipment. At the same time, adding PLC combined with Matlab signal collection to system can be useful to debugging and monitoring of system and control the system operation.Finally, the orthogonal experiment optimizes the system parameters. With many adjustable parameters, designing parameters of L933orthogonal test plan to screen advantage parameter combination according to the running status with different parameters of the system that have been collected in debug link. Those results can be use as reference when setting parameters for a combination run time of the whole system and equipment.
