中文摘要:
采用热弹性模型,对光学薄片点胶过程进行了有限元分析。对点胶后影响工件面形变化(Deltap)的工艺参数进行了优化。研究结果表明,对于光学薄片(直径为100mm,厚度为2mm),宜选择具有高弹性模量和低热膨胀系数的薄底板材料,且胶点的半径、个数及弹性模量越小,Deltap越小;胶点位置应该避开高Deltap区域;胶点的热膨胀系数对 Deltap的影响较小。

英文摘要:
By using the thermoelastic model,the finite element analysis of dispensing process of optical slices is performed.The process parameters which influence the surface deformation of workpieces(Deltap)after dispensing are optimized.For an optical slice with a diameter of 100mm and a thickness of 2mm,a thin base plate with high elastic modulus and low thermal expansion coefficient is the optimal selection.Deltapdecreases with the decreases of radius,number and elastic modulus of glue dots.The glue dot position should avoid the highDeltapzones.The thermal expansion coefficient of glue dots has little influence onDeltap.
