Research on automatic winding system of thermal battery insulation cotton based on digital twin
In order to improve the efficiency and quality of thermal battery insulation cotton winding process,an automatic insulation cotton winding system based on digital twin technology was developed.Firstly,the digital twin mapping structure model of the automatic winding device of insulation cotton was created by NX MCD software,and the information interaction and state detection between the model and the actual physical device and control device were realized through TIA Portal software,so as to reflect the winding action and state more accurately.Then,the mechanical model of automatic winding process of insulation cotton was established to analyze the winding mechanism.Nextly,the influence of winding tension and stack rotation speed on the winding effect of insulation cotton was studied by finite element dynamics simulation,and the simulation results were imported into the digital twin system to optimize the digital twin structure layer and control layer program.Finally,the automatic winding of insulation cotton was realized successfully through joint debugging and the thermal battery stack with good coating effect was produced.The research method can effectively improve the research efficiency,accelerate the design process and reduce the trial-and-error cost,which can provide a reference for the research of automatic assembly of winding packaging.
