Manufacturing device for electrode lug made of non-aluminum metal instead of aluminum metal

Abstract

The invention discloses a manufacturing device for an electrode lug made of non-aluminum metal instead of aluminum metal. The manufacturing device comprises a first feeding mechanism, a first shearing mechanism, a conveying mechanism, a second feeding mechanism, a second shearing mechanism, a welding mechanism, a material receiving rack, a front welding plate and a rear welding plate, wherein the front welding plate is arranged between the rear welding plate and the first shearing mechanism; the first feeding mechanism is used for feeding a first metal belt onto the front welding plate; the conveying mechanism is used for enabling two ends of a second sheared metal sheet to be in lap joint with first metal at the tail end of an electrode lug metal belt on the rear welding plate and a first metal sheet on the front welding plate respectively; the welding mechanism is used for enabling two ends of a second metal belt to be welded with the first metal on the rear welding plate and the first metal sheet on the front welding plate respectively; and the material receiving rack is used for rolling the electrode lug metal belt, so that the first metal sheet on the front welding plate moves onto the rear welding plate. The welding device for the electrode lug made of non-aluminum metal instead of aluminum metal provided by the invention is high in precision degree, high in welding quality and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a manufacturing device for aluminum-to-non-aluminum metal tabs. Background technique [0002] The material of the positive tab of the soft-packed lithium-ion battery is usually pure aluminum. When the battery is processed and assembled, the positive and negative electrodes of the battery need to be connected to other electronic components by welding. However, the positive tab made of pure aluminum cannot be directly connected. solder. The existing process is usually to weld a section of nickel strip on the leading end of the positive tab of the battery, and then solder through the nickel strip. This process is called the aluminum-to-nickel process of the positive tab of the flexible packaging lithium-ion battery. [0003] Traditional welding uses manual welding, which has low production efficiency, high labor intensity, and difficult to guarantee welding qu...

[0003] Traditional welding adopts manual welding, which has low production efficiency, high labor intensity, and difficult to guarantee welding quality

In order to improve work efficiency, the Chinese patent document CN103659282A discloses an automatic welding tab device, which automatically cuts the tabs and welds them on the pole pieces, which improves the efficiency of welding tabs and reduces the labor intensity of workers, but is not conducive to storage

For the convenience of storage, the aluminum strip is generally interrupted and welded with both ends of the nickel sheet to form an aluminum-to-nickel metal strip for storage. When in use, a section is cut from the aluminum-to-nickel metal strip. Based on this, someone has introduced an aluminum-to-nickel metal strip. The aluminum metal tab welding device welds the cut nickel sheet to the aluminum strip, and cuts the aluminum strip under the nickel sheet to form an aluminum-nickel metal strip, which is wound and stored, with high production efficiency and convenient storage. would waste a lot of aluminum
