Ultrasonic welding assembly and method of attaching an anvil to a bracket of the assembly

摘要

An ultrasonic welding assembly having an ultrasonic horn and an anvil having first, second, and third plate portions is provided. The third plate portion is coupled between the first and second plate portions. The first plate portion has a first knurled region on a first side disposed proximate to the ultrasonic horn, and the second plate portion has a second knurled region on the first side. The third plate portion has a first aperture extending therethrough. The assembly further includes a bracket that receives the second side of the anvil for holding the anvil thereon. The bracket has a second aperture extending therethrough that aligns with the first aperture, such that a coupling member extending through the first and second apertures removably couples the anvil to the bracket.

1. A method for attaching an anvil to a bracket of an ultrasonic welding assembly, the anvil having first, second, and third plate portions, the first and second plate portions extending generally perpendicular to one another, the third plate portion being coupled between the first and second plate portions, the first, second, and third plate portions defining first and second sides, the first plate portion having a first knurled region on the first side, the second plate portion having a second knurled region on the first side, the third plate portion having a first aperture extending therethrough, the method comprising:
disposing the second side of the anvil against a portion of the bracket such that the first aperture in the third plate portion aligns with a second aperture in the bracket, and a portion of the second plate portion is received in a notch of the bracket, and the first knurled region is configured to be disposed proximate to an ultrasonic horn; disposing a coupling member through the first aperature in the third plate portion and the second aperture in the bracket to fixedly couple the anvil to the bracket when the portion of the second plate portion is received in the notch of the bracket; when the first knurled region has a degraded configuration, removing the coupling member from the first aperture in the third plate portion and the second aperture in the bracket to remove the anvil from the bracket including removing the portion of the second plate portion from the notch in the bracket; after removing the coupling member from the first aperture in the third plate portion and the second aperture in the bracket, then disposing the second side of the anvil against the portion of the bracket such that first aperture in the third plate portion aligns with the second aperture in the bracket, and a portion of the first plate portion is received in the notch of the bracket, and the second knurled region is configured to be disposed proximate to the ultrasonic horn; and disposing the coupling member through the first aperture in the third plate portion and the second aperture in the bracket to fixedly couple the anvil to the bracket when the portion of the first plate portion is received in the notch of the bracket.
