Abstract

Abstract: 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%.

Key words: industrial robot, standard operation time, series, parallel
