摘要: 团队前期提出了无需高分子材料的熔石英元件室温模压成形方法,虽然证明了此方法的可行性,但工艺参数影响规律尚不明确。针对上述问题,基于控压控速的模压装置,进行了熔石英成形质量的工艺参数研究。设计的模压装置可提供的最大压制力为15 kN,压制速率可精确至0.01 mm/s,并针对模压过程提出力位协同控制策略。通过模压工艺参数影响规律试验,发现压制力过大或过小时,均会显著增大熔石英透镜表面粗糙度,而压制速率的提升,使得熔石英透镜表面粗糙度和轮廓最大翘曲均呈现上升趋势。基于优化后的模压工艺参数开展微透镜阵列模压试验,通过点光源成像,验证了模压工艺参数优化对于提升微透镜阵列的光学性能具有重要意义。

Abstract: In the early stage, the team proposed a room-temperature molding method for fused silica components that do not need polymer materials. Although the feasibility of this method had been proven, the influence of process parameters was still unclear. In response to the above issues, a study was conducted on the process parameters of fused silica forming quality based on a pressure controlled and speed controlled molding device. The designed molding device is capable of providing a maximum compression force of 15 kN, with a compression rate controllable to an accuracy of 0.01 mm/s. Additionally, a force-position coordinated control strategy is proposed for the molding process. Through experiments on the influence of molding process parameters, it is found that both excessive high or low pressing forces significantly increase the surface roughness of fused silica lenses. Moreover, the increasing pressing rate led to a rise in both the surface roughness and the maximum contour curvature of the fused silica lenses. Based on the optimized molding process parameters, the miniature lens array experiment is conducted. Through point light source imaging, it is verified that the optimization of molding process parameters plays a crucial role in enhancing the optical performance of the miniature lens arrays.
