Title:
ULTRASONIC WELDING TIP, ULTRASONIC WELDING MACHINE, AND METHOD FOR PRODUCING BATTERY
Document Type and Number:
WIPO Patent Application WO/2013/105361
Kind Code:
A1
Abstract:
In the present invention a plurality of protrusions are formed at a machined surface (11) of a tip (10) contacted to a member to be welded during ultrasonic welding. When the machined surface is seen head-on, at least one of the protrusions disposed at the outermost periphery of the plurality of protrusions is a chamfered protrusion (120) that has been chamfered in a manner so as to have, on the peripheral contour line (121), an arc (121r) of radius R satisfying R ≥ A/6, where A is the outer dimension in one direction thereof. As a result, it is possible to reduce the occurrence as a result of ultrasonic welding of breakage of a foil that is the member to be welded.
