Device for judging screw tightening abnormality, learning model generating apparatus, method for judging screw tightening abnormality, learning model generation method, and program for judging screw tightening abnormality
Problem to be solved: to provide a screw tightening abnormality determining apparatus, a learning model generating apparatus, a method of determining a screw tightening abnormality, a learning model generating method and a program for determining a screw tightening abnormality, which can improve the accuracy of judgment of the tightening abnormality.Solution: a data processing section 12 for generating inversion time series data by inverting a time axis of time series data representing a series of measured values of the clamping torque from the start of the screw tightening operation to the end of the screw clamping operation by an automatic screw tightening apparatus, andThe generated time series data andAn operation part 13 and an abnormality determining part 17 for determining the screw tightening abnormality are determined based on the coincidence between the time series data obtained from a series of tightening torque during the normal screw tightening operation and the coincidence time series dataWithout being affected by variations in torque measurements occurring during a period of time from the beginning of a screwEasily identify start position of inversion time series dataDetermination of coincidence is made.Diagram
