An end effector and associated systems and methods for printing ink on a surface is disclosed. The end effector comprises a main block including a back plate. The end effector also includes a plurality of slice assemblies slidably coupled to the back plate. Each one of the plurality of slice assemblies includes a printhead and a y-actuator. The y-actuator is selectively operable to extend and retract the printhead, parallel to a y-axis in first directions, and relative to the back plate. The end effector further includes a plurality of z-actuators coupled to the back plate. Each one of the plurality of z-actuators is selectively operable to extend and retract a corresponding one of the plurality of slice assemblies, parallel to a z-axis in second directions, which is perpendicular to the y-axis and relative to the back plate.

Multi-printhead end effector and associated system and method

An end effector for printing ink on a surface is disclosed. The end effector comprises a primary block comprises a primary-block body. A plurality of primary-printing modules are coupled to the primary-block body and translationally moveable, via a corresponding first actuator. Each one of the primary-printing modules includes at least one printhead which is adjustable, relative to the primary-block body. The printhead may be adjusted by at least one of a second actuator, configured to rotate the printhead about a first axis, or a third actuator, configured to rotate the printhead about a second axis. In some examples, a fourth actuator is configured to rotate at least one printhead, relative to at least one other printhead, about a third axis. Additionally, at least one trailing block can be coupled to the primary block so that the at least one trailing block is movable relative to the primary block.

A system for fabricating a composite structure includes a ply carrier including a ply support surface configured to support at least one composite ply. The system includes a carrier transfer device configured to convey the ply carrier. The system includes a lamination system configured to selectively apply the at least one composite ply to the ply support surface of the ply carrier. The system includes a transfer system configured to remove the ply carrier from the carrier transfer device and to apply the at least one composite ply to at least a portion of a forming surface of a forming tool. The system includes a forming system configured to form the at least one composite ply over the at least a portion of the forming surface of the forming tool.

System and method for fabricating a composite structure

A system for placing a composite ply includes a transfer end effector that is movable relative to a carrier transfer device, configured to convey a ply carrier that supports the composite ply, and a placement end effector that is movable relative to the transfer end effector and to a forming tool. The transfer end effector is configured to remove the ply carrier, supporting the composite ply, from the carrier transfer device and to position the ply carrier for removal by the placement end effector. The placement end effector is configured to remove the ply carrier from the transfer end effector and to apply the composite ply to the forming tool.

Composite ply placement system and method

An apparatus for forming a material layer onto a form tool may include at least one nosepiece configured to laterally sweep a ply carrier onto a form tool contour. The apparatus may include a pair of tension arms configured to support opposing lateral sides of a ply carrier having a material layer mounted to a lower surface thereof. The apparatus may include one or more actuators configured to position the tension arms during forming of the ply carrier to the form tool contour. The one or more actuators may be configured to sense and control lateral tension in the ply carrier during forming of the ply carrier to the form tool contour.

Apparatus and method for automated layup of composite structures

An apparatus for supplying one or more strands of a relatively wide tape to a high-speed graphite tape laminating machine may include a tape supply reel and a backing paper take-up reel rotatably mounted on the machine, a dancer roller mounted on the machine for lateral movement thereon, and a mechanism for actively controlling the rotation of the tape supply and backing paper take-up reels and the lateral movement of the dancer roller relative to the support frame such that the respective tensions in the tapes are maintained substantially constant during both an on-the-fly tape add operation and an on-the-fly tape cut operation of the laminating machine.
