Publication number: 20230048890Abstract: A coating applicator tool head configured for use with a robotic maintenance device includes a tool head body with a frame, a supply container, a drive for actuating delivery of flow of coating from the supply container, a feed tube, a nozzle receiving flow from the feed tube, and a spreading tool such as a roller brush or a spatula receiving flow from the nozzle. The coating applicator tool head is moved by an articulated arm of the maintenance device over surface of a wind turbine blade containing damage such that the roller brush or spatula can apply layers of the coating to cover and fill in the damage. The nozzle directly supplies coating continuously onto the roller brush or the spatula, and the drive can be configured to independently adjust supply of two or more different components in the supply container that may be mixed to form the coating.Type: ApplicationFiled: December 18, 2020Publication date: February 16, 2023Inventors: Ivar J.B.K.
