Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to a moving track of a welding robot. Background Art

[0002] Effective welding quality control by welding robots requires describing the dynamic processes or models of welding. Because arc welding dynamics are complex and involve numerous uncertainties, obtaining an accurate mathematical model is extremely difficult. By utilizing direct and indirect experimental data from welding process sensors and applying a rough set knowledge acquisition algorithm, a knowledge model of the welding process is established. This model serves as a crucial basis for the design of an intelligent controller for the robotic welding process. The structure of the rough set knowledge processing system for the welding process, centered around the knowledge model M, is shown in the figure. It includes the knowledge model M, data expansion methods, discretization methods, methods for converting the model output format, and knowledge reasoning methods. It is primarily used to predict system output based on system input.

By adding corresponding mechanisms to the mobile track, the utility model reduces the possibility of displacement between the welding robot and the track during operation, making the welding robot more accurate in welding the workpiece, improving the yield rate of the welded workpiece, reducing the possibility of the welded workpiece being wasted, and at the same time reducing the probability of the welding robot being damaged by impact, thereby increasing the service life of the welding robot.
