摘要
以工业机器人为研究对象,提出工业机器人完成一道工序的标准工时模型。针对工业机器人工作特点,得出工业机器人完成一道工序的标准工时构成要素;分别讨论单台工业机器人、多台工业机器人串联、多台工业机器人并联组成一道工序的工作特征,基于可靠性等相关理论,推导这3种情况下该工序的正常工时(t)、平均故障修复时间(MTTR)、平均预防性维修时间(MPMT)的数学模型;其中从工序能力出发,将并联工业机器人转化成串联形式进行模型推导。以某条智能生产线上各工业机器人为例,与正常工时相比,基于新的标准工时得出的标准产能与实际产能的误差由4.29%下降到1.72%。
Taking industrial robots as the research object,the standard operation time model for industrial robots to complete a process is proposed.According to the characteristics of industrial robot production,the components of standard operation time are obtained for industrial robots to complete a process.The characteristics of a single industrial robot,multiple industrial robots in series,and multiple industrial robots in parallel are discussed.Based on reliability and other related theories,the mathematical model of the normal operation time(t),mean time to repair(MTTR),and mean preventive maintenance time(MPMT)of the process in these three conditions is derived.Among them,based on process capability,the parallel industrial robot is transformed into a series form for deducing the standard operation time model.Taking the industrial robots of an intelligent production line as an example,compared with normal operation time,the error rate between the standard production capacity based on the new standard operation time and the actual production capacity drops from 4.29%to 1.72%.
