Abstract

Systems and methods are provided for exchanging electrode tips, e.g., electrode tips used in resistance spot welding, and disposing of used/unusable electrode tips. Used/unusable electrode tips may be collected, e.g., while within an assembly line. Such used/unusable electrode tips may be routed to a receptacle(s) reside outside the assembly line. Accordingly, disposing or removing of the used/unusable electrode tips can be accomplished without stopping the assembly line, and decreasing any chance for safety events.

First claim

What is claimed is:

1. A system, comprising: a first receptacle adapted to receive a welding electrode tip for disposal, from an electrode tip changing unit; and a second receptacle adapted to receive the welding electrode tip from the first receptacle, wherein the second receptacle and the first receptacle are operatively connected via a connecting mechanism, the connecting mechanism comprises a route through which a propellant moves the welding electrode tip from the first receptacle to the second receptacle.

2. The system of claim 1 , wherein the first receptacle comprises an input chamber adapted to receive the welding electrode tip from an automated electrode tip changing unit adapted to remove and dispose of the welding electrode tip in the input chamber.

3. The system of claim 2 , wherein the first receptacle comprises an output chamber adapted to receive the welding electrode tip from the input chamber.

4. The system of claim 2 , wherein the automated welding electrode tip changing unit is operatively connected to a welding assembly from which the welding electrode tip is received.

5. The system of claim 2 , wherein the input chamber comprises a funneled receptacle.

6. The system of claim 1 , wherein the second receptacle comprises a removable container adapted to capture the welding electrode tip.

7. The system of claim 1 , wherein the electrode tip changing unit is part of an automated manufacturing line.

8. The system of claim 1 , wherein the first receptacle comprises an input chamber adapted to receive the welding electrode tip from an automated electrode tip changing unit adapted to remove and dispose of the welding electrode tip in the input chamber.

9. A system, comprising: a first receptacle adapted to receive a welding electrode tip for disposal, wherein the first receptacle comprises an input chamber adapted to receive the welding electrode tip from an automated electrode tip changing unit adapted to remove and dispose of the welding electrode tip in the input chamber, and an output chamber adapted to receive the welding electrode tip from the input chamber; and a second receptacle operatively connected to the first receptacle and adapted to receive the welding electrode tip from the first receptacle, wherein the second receptacle and the first receptacle are operatively connected via a hose through which a propellant moves the welding electrode tip from the output chamber of the first receptacle to the second receptacle.

10. The system of claim 9 , wherein the propellant comprises a compressed or pressurized gas.

11. The system of claim 8 , wherein the first receptacle comprises an output chamber adapted to receive the welding electrode tip from the input chamber, and wherein the propellant moves the welding electrode tip from the output chamber of the first receptacle to the second receptacle.

12. A system, comprising: a first receptacle adapted to receive a welding electrode tip for disposal from an electrode tip changing unit; and a second receptacle adapted to receive the welding electrode tip from the first receptacle, wherein the second receptacle and the first receptacle are operatively connected via a connecting mechanism, the connecting mechanism comprising a route configured to permit a propellant to move the welding electrode tip from the first receptacle to the second receptacle.
