Abstract
The end-effector includes an articulating frame mounted on an indexable boom. Tool modules mount on the end-effector and connect to a workpiece. Each tool module includes a flexible dress package including a cable carrier. A channel rail is supported by the end-effector frame and guides the cable carrier. A setup tool and associated process can reconfigure the positions of the tool modules and the frame and boom of the end-effector.
Claims17
An end-effector attachable to a robotic arm for interacting with a workpiece, comprising:
- an articulating frame mechanically coupled to a master boom, the master boom including a straight boom coupled to an offset boom;
- the articulating frame comprising a fixed pane hingedly coupled to a rotating pane, the rotating pane adjustable to and lockable at an angular position relative to the fixed pane;
- the fixed pane mechanically coupled to the straight boom;
- the articulating frame and the straight boom rotatable around a longitudinal axis of the straight boom and relative to the offset boom;
- a tool module mounted on the articulating frame and including an end element interacting with the workpiece;
- a flexible conductor coupled to the tool module;
- a flexible dress package including a flexible cable carrier routing the flexible conductor to the tool module;
- and
- the end element operatively connected to a controllable power source via the flexible conductor.
An end-effector attachable to a robotic arm for interacting with a workpiece, comprising:
- an articulating frame mechanically coupled to a master boom;
- the articulating frame comprising a fixed pane hingedly coupled to a rotating pane, and a lockable clutch assembly;
- the rotating pane adjustable to a preferred angular position relative to the fixed pane;
- the lockable clutch assembly lockable at the preferred angular position;
- the fixed pane mechanically coupled to the master boom;
- the articulating frame rotatable around a longitudinal axis of the master boom;
- a tool module mounted on a tubing element of the articulating frame and including a configurable end element for interacting with the workpiece;
- and
- a flexible dress package routing a flexible conductor to the tool module.
Method to set up an end-effector attachable to a robotic arm, the end-effector including a tool module comprising an end element configurable to interact with a workpiece, the end-effector including an articulating frame coupled to a master boom device including a straight boom coupled to an offset boom, the articulating frame comprising a rotating pane hingedly rotatably coupled to a fixed pane, the method comprising:
- placing the end-effector on a setup stand;
- connecting a setup tool to the robotic arm;
- manipulating the tool module with the setup tool, including sliding and swinging the tool module to a preferred XY position relative to the articulating frame with the setup tool and pressing the end element of the tool module to a preferred Z position;
- engaging an input lever of the articulating frame with the setup tool and hingedly rotating the rotating pane relative to the fixed pane to a preferred articulation angle;
- and
- indexably rotating the straight boom relative to the offset boom.
