With the rapid development of consumer electronics industry, the demand for 3D curved screen in industry is also growing. At present, 3D curved screen is mass produced through glass molding process. However, due to the complex rheological properties of glass melt and the intricate deformation mechanism of glass molding process, the final geometry of the screen is difficult to predict. In this paper, the glass molding process for 3D curved screen is analyzed by finite element transient analysis. The trend of screen shape change is obtained and the final geometry of the screen is predicted. The results show that geometric fillet and rheological parameters have great influence on the flow of glass melt in glass molding process. This study is helpful for the selection of parameters of glass molding process and the design of 3D curved screen.
随着消费电子行业的快速发展，工业领域对3D曲面屏的需求也在不断增长。目前，3D曲面屏通过玻璃模压工艺进行大规模生产。然而，由于玻璃熔体复杂的流变特性以及玻璃模压工艺复杂的变形机制，屏幕的最终几何形状难以预测。本文通过有限元瞬态分析对3D曲面屏的玻璃模压工艺进行了分析。得到了屏幕形状变化趋势并预测了屏幕的最终几何形状。结果表明，几何圆角和流变参数对玻璃模压过程中玻璃熔体的流动有很大影响。该研究有助于玻璃模压工艺参数的选择以及3D曲面屏的设计。
