Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the utility model comprises plate body, plate body is provided with multiple laser passing hole, the setting position of laser passing hole and the welding position one_to_one corresponding of power brick bus-bar, the left side of plate body, right side are respectively provided with row's upper plate fixing hole.During use, by being screwed into screw in upper plate fixing hole plate body of the present utility model covered the back side of nitrogen upper plate, the air channel of back on nitrogen is made to form venting channels, nitrogen upper plate there is the laser passing hole corresponding with the utility model plate body, form the train wheel bridge of bus-bar weld jig, the below of train wheel bridge is the welding pallet as lower plate.During welding, the copper bar in parallel placing nickel sheet is put on welding pallet, again train wheel bridge is pressed in copper bar in parallel and nickel sheet, laser weld is carried out successively by the welding position of laser passing hole to copper bar in parallel and nickel sheet one by one, complete multi-point welding, while welding, nitrogen flows into from the passage nitrogen upper plate, the welding position on bus-bar is flowed to again through venting channels, laser passing hole, thus the oxygen in air-isolation, make solder joint can not oxidizing blackening, improve firm welding degree, guarantee both quality and quantity, increase work efficiency.
As preferably, described plate body is provided with a copper bar emptiness avoiding hole in parallel, and copper bar emptiness avoiding hole in parallel is strip and is positioned at the side of plate body.Copper bar in parallel has individual flanging, and when holder copper bar in parallel and nickel sheet, the flanging on copper bar in parallel just in time snaps in copper bar emptiness avoiding hole in parallel.
As preferably, the middle part of described plate body is provided with multiple upper plate fixing hole, and the upper plate fixing hole being positioned at plate body middle part to be distributed on plate body and dispersedly near corresponding laser passing hole.The connectivity robustness of further raising nitrogen lower plate and nitrogen upper plate and tight ness rating, guarantee that the nitrogen flowed into from nitrogen upper plate passage only flows out laser passing hole from venting channels, from other local outflow of plate body, can not reach the effect of better isolation oxygen.
As preferably, described laser passing hole is from left to right scattered in four row on described plate body; First row and the leftmost side one row laser passing hole have 9, every 3 compositions one group, and 3 laser passing hole in a group are scattered in isosceles three and separate shape, and three groups of laser passing hole are arranged in three row; In its excess-three row laser passing hole, often row laser passing hole has 6, and every 2 compositions one group are also arranged in three row, and 2 laser passing hole in a group are interspersed.Laser passing hole on plate body on the magnitude setting of laser passing hole and setting position and nitrogen upper plate is consistent, also consistent with the welding position on power brick bus-bar.
As preferably, described plate body adopts aluminium material.Easy to make, heat-proof corrosion resistant loses, and can not affect Laser Welding welding operation.
The beneficial effects of the utility model are: cover back on the nitrogen matched with it, form fixture train wheel bridge, after once clamping bus-bar and multiple nickel sheet, laser welding operation can be carried out to all welding positions on bus-bar, realize multi-point welding, nitrogen can be passed to welding position again while welding, isolated metal contacts with the oxygen in air, effectively prevents solder joint oxidizing blackening, guarantees that welding is more firm, guarantee both quality and quantity, increase work efficiency.
