Title:

TAB SOLDERING APPARATUS AND TAB SOLDERING METHOD

Document Type and Number:

WIPO Patent Application WO/2021/098890

Kind Code:

A1

Abstract:

A tab soldering apparatus (20) and a tab soldering method. The tab soldering apparatus (20) comprises: a first foil material delivery mechanism (21) used for delivering a first foil material (14); a current collector delivery mechanism (22) used for delivering a composite current collector (10); a second foil material delivery mechanism (23) used for delivering a second foil material (15); and a soldering device (24). The soldering device (24) is configured to simultaneously clamp the first foil material (14) and the second foil material (15), such that the composite current collector (10) is clamped between the first foil material (14) and the second foil material (15) in a manner to allow the first foil material (14) and the second foil material (15) to be soldered separately onto two opposite surfaces of the composite current collector (10). Also provided is a winding mechanism (25) used for winding the composite current collector (10) of which the two opposite surfaces are separately soldered with the first foil material (14) and the second foil material (15).
