远程激光焊接(RLW)由于其加工速度快、投资少、单针成本低和工艺灵活性等优点，近年来受到越来越多的关注。然而，它在汽车装配方面的潜力仍然没有得到充分开发，主要是因为涉及系统、工艺和夹具设计的挑战，以及部件变化的挑战。提出了一种集成的RLW过程快速部署框架，以提高RLW在装配系统中的“首次正确”实现。它实现了系统布局、任务分配、夹具布局、工艺参数、机器人路径规划和编程的闭环优化，作为一种相互关联的迭代方法。结果在汽车车门总成的中试研究中得到了验证。(C)2015年CIRP。
Remote laser welding (RLW) has received increased attention in the recent years due to its benefits in terms of processing speed, lower investment, cost per stitch, and process flexibility. However, its potential in automotive assembly remains under exploited, mainly due to challenges involving system, process and fixture design, and part variation challenges. In this paper, an integrated rapid deployment framework for RLW process is proposed to improve 'right-first-time' implementation of RLW in assembly systems. It enables closed-loop optimization of system layout, task assignment, fixture layout, process parameters, robot path planning and programming as an interlinked iterative approach. The results are demonstrated in an automotive door assembly pilot study. (c) 2015 CIRP.
