SYSTEMS AND METHODS FOR IMPROVED ULTRASONIC WELDING USING A MULTI-HEIGHT ENERGY-DIRECTING DEVICE

摘要

A multi-height energy-directing device, for facilitating staged welding together of workpieces. The device includes multiple elements extending from a body, wherein the elements do not all have a same height. Each element of a first group of the elements has a first height while each element of a second group of the elements has a second height differing from the first height. The elements are configured to channel welding energy through the device in a pre-determined manner. The predetermine manner includes channeling the energy through taller, primary, elements, of said elements, in an initial stage of the welding process, while passing none through shorter, secondary, elements, of said elements, in the initial stage.

1. A multi-height energy-directing device, for facilitating staged welding together of workpieces, comprising:
multiple elements extending from a body, wherein the elements do not all have a same height; wherein each element of a first group of the elements has a first height while each element of a second group of the elements has a second height differing from the first height; wherein the elements are configured to channel welding energy through the device in a pre-determined manner; and wherein the predetermine manner includes channeling the energy through taller, primary, elements, of said elements, in an initial stage of the welding process, while passing none through shorter, secondary, elements, of said elements, in the initial stage.
