摘要
针对航空线束生产过程劳动强度大,自动化程度低的问题,研发了航空线束自动布线设备,以布线机器人为核心执行机构,能够自动完成整个布线过程,极大地提高了航空线束的生产效率,降低了劳动强度.针对自动布线机器人生产过程中的布放拐点柱和铺设导线2个关键环节,提出基于视觉反馈的拐点柱插入方法和象限判别布线轨迹规划方法,降低了拐点柱插入失败的风险,解决了机器人布线轨迹规划难题.开展的相关实验中,共布放1014根拐点柱,未出现插入失败的情况,可在13.1～13.6 s的时间内完成单根拐点柱的布放工作;共铺设导线1385根,总长度10909 m,简单结构线束平均布线速度可达0.875 m/s,复杂结构线束平均布线速度可达0.652 m/s.
Abstract
The production of aviation harness features high labor intensity and low automaticity.Against this backdrop,the aviation harness automatic wiring equipment has been developed,which takes the wiring robot as the core actuator and automatically completes the entire wiring process,substantially improving the production efficiency of aviation harness and reducing the labor intensity.This paper investigates the two key links of laying inflection joint columns and wires in the production process of automatic wiring robot.Then,it proposes an inflection joint column insertion method and quadrant judgment routing trajectory planning method based on vision feedback,aiming to reduce the risk of inflection joint column insertion failure and address the problem of robot wiring trajectory planning.In our experiments,a total number of 1014 inflection joint columns are deployed,and no insertion failure has occurred.The deployment of a single inflection joint column is completed in 13.1～13.6 seconds and a total number of 1385 wires with a total length of about 10909 m are laid.The average wiring speed of simple structure harnesses reaches 0.875 m/s,and that of complex structural harnesses 0.652 m/s.
