Abstract

The invention aims to provide a waveform recognition method and device for a servo welding system. The waveform recognition method comprises the steps that: a reference program is determined accordingto motion control of a servo welding system and program starting information; the waveform recognition model of the servo welding system is established according to a reference program; the current waveform information of motion control of the servo welding system is recognized when the reference program runs by utilizing the waveform recognition model; and it is determined whether the servo welding system is driven abnormally or not according to the current waveform information. Therefore, consistency with industrial logic is achieved, the abnormal state of the servo welding system is accurately recognized and reflected through deviation of the position, the number of needed input parameters is small, and communication resources can be saved.

Description

technical field

[0001] The present application relates to the field of data analysis of mechanical equipment, in particular to a waveform recognition method and equipment for a servo welding system. Background technique

[0002] As a joining process, resistance spot welding is widely used in the manufacturing process. The resistance spot welding process usually needs a servo welding system to realize, and the servo drive system is the core component of the servo welding system, which has a great influence on the stability and reliability of the process. Therefore, the development of an abnormal diagnosis method for the servo drive system can effectively avoid welding quality defects of products, reduce unplanned downtime, reduce costs, and improve economic benefits.

[0003] Some existing technologies that add additional sensors, such as vibration and temperature sensors, can realize abnormality diagnosis function to a certain extent, but the cost of installing sensors, the...
