Title:
ULTRASONIC WELDING METHOD OF A LARGE NUMBER OF LAMINATED METALLIC FOILS
Document Type and Number:
Japanese Patent JP3209133
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide excellent welding without breaking a metallic foil by arranging a protective metallic sheet on an upper side on a horn abutting side of a large number of laminated metallic foils, and performing the ultrasonic welding.
SOLUTION: Metallic foils which are works to be joined are laminated on a working surface of an anvil, and an ultrasonic oscillation horn to be moved parallel to the anvil is pressed thereon to weld the metallic foils to each other. A protective metallic sheet is arranged on an upper side of a large number of laminated metallic foils on the horn abutting side to perform the ultrasonic welding. Excellent welding can be obtained without breaking the metallic foils which are works to be joined irrespective of the magnitude of ruggedness of the abutting surfaces of the ultrasonic oscillation horn and the anvil even when a large number of metallic foils are laminated and welded. The protective metallic sheet is of the same material as that of a large number of laminated metallic foils to be welded, and the material is preferably annealed. In addition, the thickness of the protective metallic sheet is preferably 50-200μm.
