Abstract: A brush (200) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (102) is disclosed. The brush (200) comprises a body (202), having a rotational axis (238) and comprising a first channel (208) that comprises an inlet (209) and a first outlet (280). The inlet (209) is coaxial with the rotational axis (238) and the first outlet (280) is offset from the rotational axis (238). The brush (200) also comprises tufts (222), extending from the body (202) and each comprising at least one bristle (220) and a tip (227). The brush (200) further comprises a first tube (210), communicatively coupled with the first outlet (280) of the first channel (208) of the body (202).

Abstract: A method of manipulating a brush relative to a brush-arm assembly of an end-effector comprises locating a carriage in one of a first position or a second position relative to a stationary component. The method also comprises, with the carriage in one of the first position or the second position, different from the first position, relative to the stationary component, locating the brush-arm assembly of the end-effector with respect to the stationary component so that the brush-arm assembly is in contact with the stationary component. The method further comprises moving the carriage in a second direction toward the stationary component, from the first position to a third position, to load the brush onto the brush-arm assembly, or moving the carriage in a first direction away from the stationary component from the second position to the first position to unload the brush from the brush-arm assembly.

Abstract: A method of delivering a glutinous substance from a cartridge to an applicator comprises receiving the cartridge inside a sleeve through an inlet of the sleeve when a pressure cap, coupled to the sleeve proximate the inlet, is in an open position.

Abstract: Provided are methods and systems for applying materials at interface areas formed by fasteners and parts. Specifically, a material is delivered to an interface area such that at least a portion of a fastener remains free from this material. The interface area may be sealed such that the material is contained within that area. As such, a controlled amount of the material is dispensed in a precise location. An applicator used for this process may include a housing and inner guide slidably disposed within this housing. The material may be delivered through an annular flow channel between the housing and inner guide. The inner guide may be sealed against and, in some embodiments, centered with respect to the fastener. The housing may be sealed with respect to the part and, in some embodiments, may be rotated with respect to the part to redistribute the material at the interface area.
