摘　　要：分析一种适用于丝网印刷涂胶技术的压力式供胶法,介绍供胶设备组成;基于流体力学理论建立了供胶设备的出口速度和流量模型,分析了入口压强、供胶设备结构对出口流量的影响。采用Fluent软件对供胶设备进行了仿真分析,仿真结果验证了出口速度及流量模型的有效性。A pressure-based glue supply method and equipment for screen printing technology were proposed. Based on fluid me- chanics theory, the model of average velocity and flow rate on outlet was established, which provided relations between inlet pressure, equipment structure and outputs. A CFD simulation was also implemented to verify the theoretical results.
