摘要
复合材料表面火焰喷铝是最常用的表面层导电处理方法之一,喷铝后通常需要在铝层表面进行封孔胶喷涂,达到保护铝层的作用。目前封孔胶常用手工刷涂、手工喷涂的方式,效率低,容易产生流挂,后期需要进行大量打磨修补。封孔胶机器人自动喷涂成为发展趋势,本文针对封孔胶机器人立式自动喷涂进行了工艺参数研究。结果表明,机器人自动喷涂能有效改善封孔胶流挂现象,喷涂的封孔胶层厚度均匀,表面质量好,封孔胶与铝层间的粘接强度高达30.28 MPa,远超行业标准。
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.
