The utility model discloses a lithium ion cell tab welding device which comprises a base, and a limiting plate and a protection part are arranged at the upper end of the base. The limiting part comprises a first limiting plate and a second limiting plate, a containing space used for clamping a battery cell is formed between the first limiting plate and the second limiting plate, one side of the base extends outwards to form a supporting plate, and the second limiting plate is located at the upper end of the supporting plate; according to the welding tool, the naked battery cell can be rapidly placed and positioned before welding, so that the naked battery cell pole piece and the tab are accurately welded with the flexible connector, the welding efficiency and the welding qualification rate are improved, meanwhile, the naked battery cell main body and the welding area can be isolated in the tab welding process, and the welding quality is improved. And metal chips are prevented from splashing into or falling in
