摘　　要：针对机器人焊接关键工艺参数的选取依赖人工经验的问题,通过响应面法建立了自动化焊锡机器人THT组装工艺参数经验模型,并验证了该模型的可靠性。在此基础上,利用蒙特卡罗模拟分析关键焊接工艺参数的多参数相对敏感度,并绘制了单工艺参数区间敏感度曲线。基于敏感度原理设计了工艺参数稳定域划分方法,获得了面向焊接质量综合分的工艺参数稳定域,并将该稳定域进行压缩得到机器人焊接工艺参数优选区间为:加热温度350~368℃,焊接时间1.31~1.48 s,送锡体积1.5~2.0 mm^(3),在工艺参数优选区间内焊接质量综合分平均值为90.2分。In order to solve the problem that the selection of key process parameters of a flexible soldering robot depends on manual experience,the empirical model of its THT assembly process parameters is established with the response surface method and the reliability of the model is verified.On this basis,the multi-parameter relative sensitivity of the key process parameters is analyzed through the Monte-Carlo simulation,and their single-parameter sensitivity curve is drawn.Then,based on the sensitivity analysis,the stability region division method is designed,and the stability region of process parameters for soldering quality comprehensive score is obtained.The optimal region of process parameters of the soldering robot are acquired by compressing the stability region:soldering temperature from 350-368℃,soldering time from 1.31-1.48 s and solder feeding volume from 1.5-2.0 mm^(3).The average value of the soldering quality comprehensive score within the optimal region of process parameters is 90.2 points.
