摘　　要：为了解决波分复用器生产过程中光纤准直器耦合装配耗时长、自动化程度低等问题,设计了基于霍夫圆检测的五轴光纤准直器自动耦合装置。利用具有X、Y、Z 3个移动自由度和R、J 2个转动自由度的五轴调节平台带动U型真空吸嘴实现准直器稳定吸取和位姿调整;采用半透式红外光卡和相机模组构成视觉系统,利用霍夫圆检测获取光卡上光斑的中心坐标,通过五轴调节平台将准直器移动至与光斑中心相同的轴线上实现准直器位姿粗调;采用光功率计测量耦合光功率,由R、J自由度微调准直器获取最佳耦合位姿,实现准直器精准耦合。结果表明,自动耦合装置效率比人工提高6倍,光纤准直器耦合效率高于75%,满足产品质量要求。该研究为光纤准直器高效自动耦合提供了参考。In order to solve the problems of long time and low automation for the coupling assemble of optical fiber collimator in production of wavelength division multiplexer,an optical fiber collimator automatic coupling device with five-axis based on Hough circle detection was designed.The five-axis adjusting platform has X,Y and Z moving three degrees of freedom and R and J two rotating degrees of freedom,which was used to drive the U-shaped vacuum suction nozzle for stable suction and pose adjustment of collimator.A vision system was constructed by using semi-transparent infrared light card and camera module.The center coordinates of the spot on the optical card were obtained through Hough circle detection.Furthermore,the collimator was moved to the same axis of the center of the light spot through five-axis adjustment platform to achieve coarse alignment of collimator pose.The collimator was accurately tuned in R and J degrees of freedom to obtain the optimal coupling pose according to the coupled optical power measured by optical power meter for achieving precise coupling of the fiber collimator.The prototype test demonstrate that the efficiency of the automatic coupling device is 6 times higher than that of manual assemble,and the coupling efficiency of optical fiber collimator is larger 75%,which meets the quality requirements of the product.The research provides a reference for efficient automatic coupling of optical fiber collimator.
