In this paper,the research status of spraying equipment in the field of coating industry is reviewed.It is pointed out that the main way of coating in China is manual spraying,which is difficult to control the thickness and uniformity of coating accurately.Moreover,the coating contains a lot of organic solvents,which is harmful to the health of spraying workers.The automatic robot spraying can avoid the above problems,and has the advantages of good coating quality and high efficiency.It has been gradually applied in various fields of the coating industry,so the automatic spraying equipment is the development direction and trend of the coating equipment in the future.
