摘要:
微透镜阵列由于具有质量轻、结构小、视场大、分辨率高等优点,被广泛应用于光学领域.微注塑成型是实现其低成本批量生产的主要方法.如何高效、高精度、低成本加工模芯一直是研究的重点与难点.本文在传统微透镜阵列加工路径基础上,提出了一种正弦过渡加工路径,并对其过渡正弦的振幅和波长进行了分析,该方法有效避免了传统加工路径的不连续与突变问题.进行了正弦过渡路径优化设计和实际对比加工实验,实验结果表明该路径优化方法能有效地消除加工表面纹理,提高表面质量和加工效率.
Abstract:
Microlens array enjoys such advantages as light weight, small structure, large field of view, and high resolution, and has been widely applied in optical fields. The micro injection molding is the main method to realize batch production and reduce cost. How to machine mold core with high precision and low cost effectively has always been the focus in research. This paper proposes a new sinetransition machining path of microlens array based on the traditional machining path, and analyzes the amplitude and wavelength of the transitional sine. The proposed method avoids problems of discontinuousness and sudden change in traditional machining path. In addition, experimental results indicate that the proposed path optimization method can effectively eliminate surface texture and improve surface precision and machining efficiency.
