工业网版印刷的数学模型研究

Research on the Mathematical Model for Industrial Screen Printing

在刮刀与丝网直接接触的假定下,研究了工业网版印刷过程中浆料压强随刮刀刃口的距离的变化规律,建立了浆料压强变化的数学模型。用此模型预测浆料压强的变化,同时与现有实验进行了比较。结果表明:浆料压强随距离的增大先急剧下降,后慢慢趋于平缓,最后接近于某一常数。为工业网版印刷质量控制提供了数学模型。

Based on the assumption of direct contact between squeegee and screen mesh,the author researched the pressure evolution of stock with the distance from the squeegee tip during the industrial screen printing process,and established a mathematical model for change in the pressure of stock.This model was used for predicting the evolution of stock pressure,and it was compared with existing experimental data.The results show that firstly the stock pressure decreases sharply with the increase of the distance,then the decrease tends to become gentle,and it is finally close to a constant.A mathematical model is provided for the quality control of industrial screen printing.
