An applicator (102) for delivering a glutinous substance (168) to a workpiece (170) from an end-effector (101) is disclosed. The applicator (102) comprises a body (110) and a plunger (186). The plunger (186) comprises a gate (118), movable within an outlet portion (182) of a first channel (115) of the body (110) between, inclusively, an open position, allowing the glutinous substance (168) to flow from an inlet (116) of the first channel (115) to an outlet (117) of the first channel (115) and a closed position, preventing the glutinous substance (168) from flowing from the inlet (116) of the first channel (115) to the outlet (117) of the first channel (115). The applicator (102) further comprises an actuator (131), selectively operable to move the plunger (186) such that the gate (118) moves between, inclusively, the open position and the closed position.

A method and apparatus for applying resin to a cut edge of a composite structure, the cut edge having exposed carbon fibers. The method comprises scanning the cut edge of the composite structure with a vision system to form scanned data. The method further determines an application path for the cut edge of the composite structure using the scanned data. The method also applies the resin to the cut edge of the composite structure by controlling movement of an application tip along the application path using a controller.

Disclosed is an apparatus (10) for the application of a liquid to viscous medium (42) onto an application surface (53), comprising a port (14) for providing a connection between the apparatus (10) and a supply of said liquid to viscous medium (42) upstream of the apparatus (10), at least two volumetric delivery pumps (23) for metering volumes of said medium, said volumetric delivery pumps (23) being located downstream of said port (14), each volumetric delivery pump (23) being in fluid connection with an application valve (25) of the apparatus (10), located downstream of the volumetric delivery pump (23) for passing a metered volume of the medium (42) from the delivery pump (23) to said application valve (25). It is characteristic that the apparatus (10) comprises a flow meter (13) in fluid connection with said volumetric delivery pumps (23), which flow meter (13) is located upstream of said volumetric delivery pumps (23).

A fastener sealing tool that utilizes curable material to seal the area around a fastener connected to a surface. In one embodiment of the invention the fastener sealing tool is a manually operated tool, hand operated by a user who visually identifies the fastener to be sealed and then operates the fastener sealing tool to seal the desired fastener. In a second embodiment of the invention the fastener sealing tool is an end of arm tool for a robot that automatically identifies or is programmed to move to the location of the fastener, and then seal the fastener using the fastener sealing tool. The fastener sealing tool utilizes a load cell to control the flow of material and to detect certain unwanted conditions.

The present invention discloses an automatic adhesive spraying control system for a progressive die of a motor lamination core of a new energy vehicle. During stamping of the progressive die, a nozzle is moved downward under the effect of downward movement of a steel strip, such that a gap is defined between a side wall of a conical head of the nozzle and an inner side wall of a first conical hole of the nozzle. An ejecting hole ejects an adhesive subjected to air pressure regulation, such that different gas pressures can be used for adhesive spots and adhesive channels at different positions.
