Lithium battery welding equipment

The invention discloses lithium battery welding equipment. The lithium battery welding equipment comprises a welding table, a battery feeding mechanism, a nickel belt feeding mechanism, a double-facewelding mechanism and an unloading mechanism. The lithium battery welding equipment is characterized in that a rotary disc is arranged on the welding table, and multiple battery grooves are evenly distributed in the peripheral wall of the rotary disc; the rotary disc is sleeved with an annular sleeve, and the double-face welding mechanism comprises a substrate and an upper welding plate located onthe upper side face of the rotary disc; an upper spot-welder located above the upper welding plate and a lower spot-welder located below the welding table are slidably arranged on the substrate, andthe upper spot-welder and the lower spot-welder do synchronous movement; an upper channel is formed in the upper welding plate, and an upper cutter for cutting off a nickel belt in the upper channel is arranged on the upper wel
