AI Technical Summary

Technical Problem

Existing multi-station flexible collaborative welding positioning systems for aluminum-magnesium alloys are unable to identify and respond to dynamic offsets caused by workpiece thermal deformation. The direction of weld heat diffusion lacks dynamic tracking of the actual shape of the workpiece, resulting in fluctuations in welding accuracy and instability in the connection state of structural components.

Method used

The weld seam thermal field acquisition module analyzes the infrared temperature sensor signal to identify the main characteristic parameters of thermal diffusion. The thermal deformation trajectory recognition module determines the workpiece surface displacement. Combined with the reference drift judgment module and the fixture compensation control module, the station drift compensation is realized. The multi-station synchronous execution module adjusts the signal sending order to realize station collaborative control.

Benefits of technology

It improves the operational continuity of the welding process and the welding consistency of the overall structural components, enhances the reliability of multi-station collaboration, and ensures the stability of welding quality.
