摘要: 介绍了一种新型液压放大压电点胶系统的结构和原理,分析了该系统的喷射过程和喷射条件,结合AMESim仿真软件,搭建了该系统的开环仿真模型,仿真验证了系统结构的可行性。针对开环点胶系统的不足,重点引入PID(比例积分微分)控制算法,构成闭环控制点胶喷射系统,在仿真环境下,对开环和闭环系统的性能进行了对比,分析表明,PID闭环控制可以改进和提高压电喷射点胶系统的性能,在喷嘴直径为0.1 mm,胶体腔压强8 bar下,可以得到点胶速度为0.023 L/min、液滴直径为0.8 mm的稳定喷射液滴。

Abstract: A new type of piezostack-driven jetting dispenser was proposed which used hydraulic magnification, and analyzed its injection process and injection condition. The open loop model of dispensing system was built by AMESim software. The simulation proved the feasibility. The closed loop control system with PID (Proportion Integration Differentiation) algorithm was set up to improve performance of open loop dispensing system, and the open and closed loop control performance was compared under the simulation environment. Analysis shows that PID closed loop system can improve performance of piezostack-driven jetting dispensing system. When nozzle diameter is 0.1mm and syringe pressure is 8 bar, by closed loop control, the achieved average flow rate is 0.023L/min and the minimum diameter of stable droplets is 0.8 mm.

Key words: piezoelectric driven, AMESim simulation, jet dispensing, hydraulic magnification
