Clamp for welding small size batteries

Abstract

The utility model discloses a kind of small size battery welding clamps, it is related to battery welding technical field, including positive electrode clamp and negative electrode clamp, the boss is fixedly connected in the inside left and right sides of positive electrode clamp, the negative electrode clamp is set between left and right sides boss, the positive electrode clamp bottom left front is provided with foolproof mark, the positive electrode clamp is recessed groove shape with two sides high and middle low.Advantages are that: the utility model can carry out multiple diameter 6mm small battery laser welding operation once, compared with traditional single welding piece placement mode production efficiency is improved about 3 times, saves artificial cost, and can improve production yield, the design of positive and negative electrode clamp welding piece positioning pin plus welding piece groove can effectively control the position and tolerance of multiple welding pieces, protect product in laser welding process welding piece from having displacement, air welding, finished product size tolerance too large problem.
