Abstract
The present application relates to a roll replacing device and a tab welding apparatus. The roll replacing device includes an unwinding mechanism, a first fixing mechanism, a second fixing mechanism, a cutting mechanism, and a strip connection mechanism; wherein the first fixing mechanism is capable of following a sliding bracket to move along a first direction until a spare material strip fixed by the first fixing mechanism and a working material strip fixed by the second fixing mechanism are aligned at a strip connection station, and allows the strip connection mechanism to connect the working material strip and the spare material strip which are aligned at the strip connection station.
