Swivel link for mounting end of arm tooling
A robotic end of arm tooling system including a robotic arm having an end, and at least one swivel link assembly attached to the robotic arm. The swivel link assembly includes a flexible ball base connected to the end of the robotic arm, and a knuckle joint defining at least one adjustable axis. The flexible ball base is able to swivel relative to the adjustable axis. An adapter has a proximal end and a distal end, with the proximal end connected to the flexible ball base, and an end-effector connected to the distal end.
1. A robotic end of arm tooling system, comprising:
a robotic arm having an end;
at least one swivel link assembly attached to said robotic arm, including:
a flexible ball base connected to said end of said robotic arm, and including a knuckle joint defining at least one adjustable axis, said flexible ball base being able to swivel relative to said adjustable axis; and
an adapter including:
a proximal end and a distal end, said proximal end connected to said flexible ball base; and
a spring sleeve having said proximal end, said spring sleeve having a bore which houses a compression spring and partially houses a spring pin, the spring pin being adjacent to said compression spring and extending outwardly from the spring sleeve to said distal end; and
an end-effector connected to said distal end;
wherein said spring pin is moveable in an axial direction relative to said spring sleeve by actuating said compression spring, thereby using a spring force for damping translational forces acting on said end-effector.
2. The robotic end of arm tooling system of claim 1 , wherein said compression spring includes at least one of a coil spring, a gas spring and a disc spring.
3. The robotic end of arm tooling system of claim 1 , wherein said flexible ball base has a hollow central opening which is in communication with said bore.
4. The robotic end of arm tooling system of claim 3 , wherein said end-effector includes a vacuum cup system for applying a suction to a target part, said vacuum cup system including a suction tube, and a suction gripper for applying said suction to said target part via said suction tube.
5. The robotic end of arm tooling system of claim 4 , wherein said spring pin has a chamber with a first end positioned inside said spring sleeve and a second end, said suction tube passes through the hollow central opening in said flexible ball base and through said compression spring inside said spring sleeve, said suction tube fluidly connected to the first end of said chamber for creating a vacuum inside said chamber in communication with said suction gripper connected to the second end of said chamber.
6. The robotic end of arm tooling system of claim 1 , wherein said end-effector includes at least one of a grabber, a servo-electric gripper, a pneumatic gripper, a hydraulic gripper, and a vacuum gripper.
7. A robotic end of arm tooling system, comprising:
a robotic arm having an end;
at least one swivel link assembly attached to said robotic arm, including:
a flexible ball base connected to said end of said robotic arm, and including a knuckle joint defining at least one adjustable axis, said flexible ball base being able to swivel relative to said adjustable axis; and
an adapter including:
a proximal end and a distal end, said proximal end connected to said flexible ball base; and
a spring sleeve having said proximal end, said spring sleeve having a bore which houses a compression spring and partially houses a spring pin, the spring pin being adjacent to said compression spring and extending outwardly from the spring sleeve to said distal end; and
an end-effector connected to said distal end;
wherein said flexible ball base has a hollow central opening which is in communication with said bore;
wherein said end-effector includes a vacuum cup system for applying a suction to a target part, said vacuum cup system including a suction tube, and a suction gripper for applying said suction to said target part via said suction tube; and
wherein said spring pin has a chamber with a first end positioned inside said spring sleeve and a second end, said suction tube passes through the hollow central opening in said flexible ball base and through said compression spring inside said spring sleeve, said suction tube fluidly connected to the first end of said chamber for creating a vacuum inside said chamber in communication with said suction gripper connected to the second end of said chamber.
