8. The automatic paint spraying method of the composite main blade according to claim 7, wherein the set paint spraying parameters for the 1# track to the 11# track are:
9. The automatic paint spraying method of the composite main blade according to any one of claims 1 to 8, wherein a process flow of automatic paint spraying is implemented by adopting the automatic paint spraying method, comprising:
s1, cleaning, polishing and cleaning the surface of a main blade made of a composite material;
s2, spraying primer on the surface of the main blade of the composite material by using a robot according to a preset automatic spraying track and a preset path node, and drying to display defects;
s3, polishing, cleaning, scraping putty and drying the surface of the main blade made of the composite material;
s4, polishing and cleaning the surface of the main blade made of the composite material;
s5, spraying primer on the surface of the main blade of the composite material by using a robot according to a preset automatic spraying track and a preset path node, and drying;
and S6, polishing and cleaning the surface of the main blade of the composite material after drying, spraying finishing paint by a robot according to a preset automatic spraying track and path nodes, and drying.
