Compared with ordinary coatings, the coating method has higher requirements. It is necessary to ensure the coating uniformity and the formation of superhydrophobic micro-nano structures. Therefore, the coating thickness needs to be precisely controlled. Too thick or too thin will affect the hydrophobicity and anti-icing performance.

[0003] Chinese Patent with the authorization announcement number CN221335081U discloses a coating device for hydrophobic materials, including a protective cover. Above the protective cover, there is a hydrophobic material box. At the discharge port of the hydrophobic material box, there is a material pump.

[0062] S6. By moving the moving seat 501 in the conveying direction, the moving plate 505 is lifted and rotated, and the position adjustment structure 5 drives the three coating assemblies 401 to lift, move and rotate synchronously; then, by horizontally moving the coating assembly 401 in the middle, the positions of the coating roller 410 and the aggregate curing member 411 are adjusted, and by rotating the coating assemblies 401 on both sides, the radius lengths of the rotation of the coating roller 410 and the aggregate curing member 411 are adjusted; continuously adjust the coating position and range;
