Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding machine technology, specifically to a synchronous pressure welding head device for a multi-electrode ultrasonic welding machine. Background Technology

[0002] Currently, in the manufacturing process of lithium-ion battery cells, the cell is composed of multiple layers of cell foil stacked together. Each layer of cell foil extends out a tab foil. After the cell foils are aligned, the tab foils are also attached and aligned together. The cell foils need to be welded together to form the cell, and the tab foils need to be welded together to form the tabs. Since the tab foils are very thin, they are traditionally welded using ultrasonic welding. During welding, a bottom mold is placed under the stacked tab foils as a support. The welding head of the ultrasonic welding device is pressed onto the stacked tab foils and a certain pressure is applied to the tab foils through the welding head. The welding head directly outputs ultrasonic waves, and the resonance of atoms on adjacent tab foils is achieved under high-frequency vibration, thereby joining the tab foils together.
