Abstract

Abstract: Spraying aluminum on the surface of composite parts with flame is one of the most commonly used conductive treatment methods for surface layer, and it is usually necessary to spray the sealing glue on the surface of the aluminum layer to protect it. At present, sealing glue is commonly used by hand brushing and manual spraying, which is inefficient and easy to produce hanging, and requires a lot of polishing work in the later stage. Automatic spraying of sealing glue robot has become a development trend, and this paper conducts a process parameter study on vertical automatic spraying of sealing glue robot. The results show that the automatic spraying of the robot can effectively improve the hanging phenomenon of the sealing glue, the thickness of the sealing adhesive layer is uniform, the surface quality is good, and the bonding strength between the sealing glue and the aluminum layer is as high as 30.28 MPa, far exceeding the industry standard.

Key words: flame spray aluminum, robot spraying, sealing glue, bonding strength, composites
