| 中文摘要: |
| 蠕动泵在流体点胶领域有着良好的应用前景，为提高蠕动式自动点胶的质量，深入分析了蠕动泵的工作特性和定量点胶要求，提出了一种蠕动式点胶控制策略。将打点、画线变换为运动控制问题，采用插补实现针头和蠕动泵的协调运动控制。在此基础上，开发了一种基于SMC6480运动控制器的数控点胶系统，重点介绍了系统软件结构、自动点胶过程及其软件实现。研究表明：提出的点胶控制策略可以实现点胶动作的精确控制，有利于提高点胶精度。开发的点胶系统实现了蠕动式自动点胶，且结构开放性好，模块化程度高。 |

| Peristaltic pump possesses a good application prospect in the dispensing field. To improve the quality of peristaltic dispensing, the characteristics of peristaltic pump and the dispensing requirements were studied, and then a control strategy for peristaltic dispensing was proposed, in which the control of dotting and drawing was transformed into the motion control of syringe needle and peristaltic pump，and the coordinated control of syringe needle and peristaltic pump was realized by interpolation. On this basis，a NC dispensing system was developed based on SMC6480 motion controller, software structure and automatic dispensing program were mainly introduced in this paper. Research showed that the proposed control strategy realized accurate control of the motions of automatic dispensing, and could improve dispensing accuracy, the developed system not only realized automatic peristaltic dispensing, but also had favorable openness and high degree of modularization. |
