Abstract

A number of variations may include a weld gun and a method of operating the weld gun including a motor operably coupled to a converter. The converter may be operably coupled to a booster. A horn may be operably coupled to the booster. An anvil may be operably coupled to the horn wherein vibration of the horn may be caused by the motor. Moreover, the vibration of the horn may produce heat in order to weld a piece which may be disposed adjacent to the horn. The weld gun may not require separate or additional tooling.

First claim

What is claimed is:

1. A weld gun consisting essentially of:
a motor operably coupled to a converter;
a horn operably coupled to the converter, the horn being constructed and arranged to vibrate at about 250 vibrations per second to about 60,000 vibrations per second; and
an anvil disposed inline and opposite the horn and integrated with an arm; the horn, the arm, and the anvil forming a single integral weld gun absent additional structural connection elements, wherein the horn is constructed and arranged to vibrate and wherein the vibration of the horn produces heat to weld a piece disposed between the horn and the anvil.

2. The weld gun of claim 1 , wherein the vibrations are caused by mechanical energy.

3. The weld gun of claim 1 , wherein the weld gun is operably coupled to a robot or a robotic system.

4. The weld gun of claim 1 , wherein no additional tooling is used to weld the piece disposed between the horn and the anvil.

5. The weld gun of claim 2 , wherein the mechanical energy is produced by the converter.

6. The weld gun of claim 5 , wherein the horn fine tunes the amplitude coming from the booster and applies the appropriate amplitude to the piece.

7. The weld gun of claim 1 , wherein the weld gun is an ultrasonic weld gun.

8. An ultrasonic weld gun consisting essentially of:
a motor operably coupled to a converter;
a booster operably coupled to the converter;
a horn operably coupled to the booster; and
an anvil integrated with an arm and the horn to form a single integral weld gun absent additional structural connection elements, wherein the horn is constructed and arranged to vibrate; and
wherein the horn vibrates at about 250 vibrations per second to about 60,000 vibrations per second to produce heat to weld a piece disposed adjacent to the horn and wherein the horn is constructed and arranged to apply a force of about 40 pounds-force to about 250 pounds-force to the piece.

9. The ultrasonic weld gun of claim 8 , wherein the vibrations are caused by mechanical energy produced by the converter.

10. The ultrasonic weld gun of claim 8 , wherein the weld gun is operably coupled to a robot or a robotic system.

11. The ultrasonic weld gun of claim 8 , wherein no additional tooling is used to weld the piece disposed adjacent to the horn.

12. The ultrasonic weld gun of claim 8 , wherein the mechanical energy is moved through the booster and the converter before causing the vibrations of the horn.

13. The ultrasonic weld gun of claim 12 , herein the horn fine tunes the amplitude coming from the booster and applies the appropriate amplitude to the piece.

14. A welding method consisting of:
operating a motor wherein the motor is operably coupled to a converter;
transferring energy from the converter into a horn, wherein the horn is operably coupled to the converter;
producing heat by vibrating the horn at about 250 vibrations per second to about 60,000 vibrations per second in order to weld a piece disposed adjacent to the horn;
and wherein the horn is constructed and arranged to apply a force of about 40 pounds-force to about 250 pounds-force to the piece; and
wherein the anvil is integrally formed with an arm and the horn as part of a single integral weld gun absent additional structural connection elements.

15. The welding method of claim 14 , wherein no additional tooling is used to weld the piece disposed adjacent to the horn.

16. The welding method of claim 14 , wherein the mechanical energy is moved through a booster and the converter before causing the vibrations of the horn.

17. The welding method of claim 16 , wherein the horn fine tunes the amplitude coming from the booster and applies the appropriate amplitude to the piece.

18. The welding method of claim 14 , wherein the welding method is an ultrasonic welding method.

19. The welding method of claim 14 , wherein the anvil is operably coupled to an arm.

20. The welding method of claim 14 , wherein the arm is operably coupled to a robot or a robotic system.
