工业机器人光学加工中边缘问题的解决方法

现代光学系统发展到了自由曲面时代,也对其加工提出了更高要求.在镜面尺寸越来越大的背景下,工业机器人被逐步利用,但加工中的“边缘问题”依旧是难点之一.以进动气囊抛光头为原型设计并制作的柔性旋转抛光轮结构简单,能方便地搭载于工业机器人上,实现镜面边缘区域的加工,解决“边缘问题”.介绍了其原理、模型以及运动方式、下压距离、实物验证三个有关实验,展示了实验结果,并得到结论:合适的控制参数为下压距离小于1.5 mm,转速小于240 r/min.

The Solution to the Edge Figuring of Optical Fabrication Based on Industrial Robots

Modern optical systems now have stepped into the freeform age.Higher demands have been made on its fabrication.Industrial robots have been put to use under the background of the more and more large diameter of the lens.However the edge figuring is still a difficult problem.The soft polishing wheel which is based on the bonnet polishing tool can easily installed on the robot to process the edge part of the lens and solve the edge figuring problem.The principle,model and three experiments(movement,pressure and verification) were described.The results are shown and concluded which are the proper parameters: pressing distance is less than 1.5 mm;rotating speed is lower than 240 r/min.
