Digital Twin System of Welding Table for Rear Assembly of the Left Inner Plate of Automobile
The welding robot table was designed for the rear assembly joint of the left inner panel of automobile.First-ly,based on Visual Components,the digital twin system of the welding robot,welding tongs and welding fixtures was constructed.Then TCP protocol was developed through Python script for communication to complete the virtual and real linkage of the digital twin system.Finally,the welding quality prediction model was constructed based on BP neural network,and the prediction effect was verified through orthogonal experiments.The results of experiment show that its prediction accuracy reaches 94.81%,which is able to meet the requirements of actual production.
