Abstract:
1. An ultrasonic welding machine, comprising: a base portion having a first aperture extending therein that defines first internal threads of the base portion; an electrically non-conductive member having first and second plate portions disposed on the base portion, the second plate portion being coupled to the first plate portion and extending substantially perpendicular to the first plate portion, the first plate portion having a second aperture extending therethrough that is aligned with the first aperture; an anvil portion having a third plate portion and a welding head directly coupled to the third plate portion, the welding head extending downwardly from the third plate portion, the third plate portion disposed on the first plate portion of the electrically non-conductive member, the third plate portion having a third aperture extending therethrough that is aligned with the second aperture; a first electrically non-conductive tubular portion configured to be received in the third aperture; a first bolt configured to be received through the third aperture and the first electrically non-conductive tubular portion and the second aperture, and a portion of the first bolt being threadably received in the first internal threads of the base portion; a first electrically non-conductive washer being disposed on the first bolt such that the first electrically non-conductive washer is disposed between and contacts a head of the first bolt and the third plate portion of the anvil portion; the first bolt and the anvil portion being electrically isolated from the base portion utilizing both the first electrically non-conductive tubular portion and the first electrically non-conductive washer; and an ultrasonic welding horn disposed proximate to the anvil portion and spaced apart from the anvil portion.
