Description

Automatic change camouflage spraying robot Technical Field The invention relates to a spraying equipment technology, in particular to an automatic camouflage spraying robot. Background Camouflage paint layers often consist of complex irregular patches of multiple colors, the core difficulty of the spray process being the treatment of the different color interfaces. If the boundary is blurred, cross-colored or jagged, the integrity of the camouflage pattern will be compromised, the camouflage effect will be reduced, and even the target features will be exposed. Currently, multicolor camouflage spraying relies primarily on manual operation. Operators need to manually paste masking tapes on the surface of a workpiece, outline the boundaries of areas with different colors along a design pattern, form a physical barrier and then spray the physical barrier. After the first color is dried, the tape is torn off and re-applied to spray the second color. When the existing equipment is used, the complex three-dimensional curved surface outline is difficult to precisely attach by manual attachment, wavy edges, gaps or tilted edges are easy to generate, paint mist is permeated during subsequent spraying, serrated or fuzzy edges are formed, the integral spraying effect is affected, meanwhile, mechanical vibration generated by the spraying equipment can cause track drift at the edge of a workpiece, even if shielding is perfect, the spraying edge is feathered or fuzzy due to instability of a spray gun, and therefore an automatic camouflage spraying robot is developed.
