Design and Process Planning of Non-Structured Surface Spray Equipment for Ultra-Large Spaces in Ship Section Manufacturing

2023

Sandblasting and coating constitute a critical phase in ship manufacturing, a process currently predominantly reliant on manual labor. To enhance the efficiency and quality of the coating process for shipbuilding segments, to address the challenges shipbuilding companies face in labor recruitment and shortage, and to simultaneously elevate the level of intelligent manufacturing for ship segment coating, this research investigates equipment suitable for large-scale, non-structural surface coating in shipbuilding segments, considering the unique features of ship segments and the customary techniques employed by shipbuilding companies. The structure, size parameters, and principal components of the coating equipment are determined. Regular workspace with high performance is designated and the coating process is planned based on the working environment and the curvature characteristics of the surface to be coated. The results demonstrate that the proposed coating equipment improved efficiency by 300% compared to manual painting, providing a novel automated solution for the coating of ship segments.
