[0005] When the welding machine and the fixture are used to weld the circuit breaker of the lithium-ion battery, since the upper and lower welding pins need to be butt-jointed during the butt welding process, the upper and lower welding pins will pass a high current, so after many times of welding, the tip of the welding pin The welding slag will be "accumulated" inside the welding slag. The existence of welding slag will lead to poor welding and affect the welding quality. Therefore, it is necessary to replace the accessories of the welding machine from time to time, and because it is manual operation, there are virtual welding and welding errors caused by manual operation errors. Missing soldering and other situations lead to low product quality and welding consistency cannot be guaranteed
In addition, the efficiency of manual welding is low, which is not conducive to the improvement of production efficiency

The invention belongs to the technical field of production devices of lithium ion batteries and particularly relates to a welding jig for a lithium ion battery breaker. The welding jig comprises a base plate and an upper cover which are movably connected with each other. Nickel sheet containing grooves and aluminum-nickel cladding strip containing grooves are arranged on the base plate. Each nickel sheet containing groove and each aluminum-nickel cladding strip containing groove are communicated with each other through a connecting groove. Welding pressing claws provided with welding holes are disposed on the upper cover. When the welding jig is used, each welding hole is located in each connecting groove. Compared with the prior art, the welding jig is convenient, fast, accurate in positioning, needs no manual welding during breaker welding, and accordingly welding efficiency is improved greatly, welding consistency is guaranteed, and product yield is improved. Unscheduled replacing of welder fittings is unnecessary so that cost is saved. In addition, the welding jig is simple in structure, easy to produce and convenient for industrialized application.
Description
Technical field [0001] The invention belongs to the technical field of lithium ion battery manufacturing equipment, and particularly relates to a welding fixture for a lithium ion battery circuit breaker. Background technique [0002] Lithium-ion battery is a kind of chemical energy storage device with high energy density. With the continuous development of electronic technology, portable electronic devices such as MP3, MP4, DVD, mobile phones and notebook computers and electric vehicles are mostly used with high energy density and use Lithium-ion batteries, which have the advantages of long life and high safety and reliability, are used as power sources, which makes lithium-ion batteries have been developed by leaps and bounds. [0003] In recent years, the safety performance of lithium-ion batteries has attracted more and more attention. In order to improve its safety performance, a circuit breaker is generally installed at the front end of the lithium-ion battery. When the inte...
