However, the complexity of the spray pattern of the ESRB and the automobile surface geometric makes the spray process planning a more challenging problem. This paper aims to provide a new parameterized model of the ESRB to facilitate the thickness calculation and trajectory planning in the off-line painting programming. Firstly, according to the distribution characteristics of paint particles and the force analysis of adhesion process, a new static deposition rate model—offset asymmetric Gaussian model is proposed on the plane. The parameters in the new model have intuitive practical significance and can fully reflect the characteristics of ESRB coating deposition rate. Then based on the analysis of the relationship between the static model and uniform linear spraying deposition, the static model is established by measuring the layer data of corresponding uniform linear spraying. In order to further simulate the paint thickness on curved surfaces, the projection model with variable spraying distance and deposition point normal deflection is also deduced. Finally, a parameterized static model and sampling points library are established which provide efficient and accurate prediction of static deposition result, and is more suitable for off-line programming. Three different groups of simulation proved that the proposed static deposition rate model has high calculation accuracy for different working conditions and fast simulation speed for different spraying parameters.

A parametric distribution model of electrostatic spray rotating bell and application for automobile painting / Peilun Zhang in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 20, N° 5 (09/2023)

However, the complexity of the automobile surface geometry and the spray pattern produced by ESRB painting makes the trajectory planning and the determination of spraying parameters challenging. This research presents a coating thickness distribution model for ESRB atomizer with uniform motion and establishes a parametric model to express the functional relationship between the thickness distribution model and atomizer parameters. The proposed parametric model aims to provide a guideline for the determination of spraying parameters in the process of off-line programming in the painting industry. Firstly, a novel feature points fitting distribution model was established based on the characteristics of ESRB uniform linear spraying coating. The model can fully visualize the cumulative profile characteristics of coatings. Secondly, the orthogonal experiment, multilevel and multifactor, was designed to analyze the variation of feature points with the painting parameters. Then, based on the requirements of the spraying process, an objective function is established for the coating thickness and other indicators of each area, and a genetic algorithm is used to solve it, so as to determine the ESRB spraying parameters. Finally, three simulation experiments show that the new model is effective and has high prediction accuracy, which can be effectively applied to the ESRB spraying system.
