Spot weld robot incorporating rechargeable docking port
First Claim
1. A system for performing a welding operation using a robot, the robot having an articulated and movable arm terminating in a weld gun, said system comprising:
- a portable and rechargeable electrical supply unit adapted to being secured to the robot arm in communicable fashion with the weld gun, said electrical supply unit including a charging component and a delivery component; and
a docking unit positioned at a remote and accessible location relative the robot arm and associated supply unit, a primary voltage supply communicating with said docking unit;
the electrical supply unit associated with the robot arm being electrically communicated with said docking unit in a first charging condition, the robot subsequently being actuated to a second operating condition in which the weld gun is engaged in a welding operation and in which said delivery component supplies a low voltage, high current amperage welding current.

Abstract
A system for performing a welding operation, such as a spot weld, using a robot incorporating an articulated and movable arm terminating in a weld gun. The system includes a portable and rechargeable electrical supply unit adapted to being secured to the robot arm in communicable fashion with the weld gun. The electrical supply unit includes a charging component, such as a battery, and a delivery (high capacitance/low voltage) component. A docking unit is positioned at a remote and accessible location relative the robot arm and associated supply unit, a primary voltage supply communicating with the docking unit. The electrical supply unit associated with the robot arm is electrically communicated with primary voltage input of the docking unit in a first charging condition. The robot arm is subsequently actuated to a second operating condition in which the weld gun is engaged in a welding operation and in which the delivery component supplies a low voltage, high current amperage welding current to the weld gun during a determined welding dwell time.

7. A spot weld robot having an articulated and movable arm terminating in a weld gun, said robot comprising:
-
a weld unit incorporated into the arm and including a current storage and delivery unit in operative communication with the weld gun; and
a docking unit positioned at a remote and accessible location relative the robot arm and associated storage and delivery unit, a primary voltage supply communicating with said docking unit;
the storage and delivery unit being electrically communicated with said docking unit in a first charging condition, the robot arm subsequently being actuated to a second operating condition in which the weld gun is engaged in a welding operation and in which said delivery unit supplies a low voltage, high current amperage welding current to the weld gun, the robot arm subsequently returning to said first charging condition in repeating and iterative fashion during each of succeeding weld cycles. - View Dependent Claims (8, 9, 10)

11. A weld current delivery system incorporating a weld gun, said system comprising:
-
a portable and rechargeable electrical supply unit adapted to being secured to the delivery system in communicable fashion with the weld gun, said electrical supply unit including a charging component and a delivery component; and
a docking unit positioned at a remote and accessible location relative the delivery system and associated supply unit, a primary voltage supply communicating with said docking unit;
the electrical supply unit associated with the delivery system being electrically communicated with said docking unit in a first charging condition, the system subsequently actuating the weld gun to a second operating condition in which the gun is engaged in a welding operation and in which said delivery component supplies a low voltage, high current amperage welding current.
