Aluminum soft connection welder and welding process

Abstract

The invention discloses an aluminum soft connection welder which comprises a rack, a welding mechanism, pressurizing equipment and a control cabinet. The welding mechanism is mounted on the rack, the pressurizing equipment is arranged above the welding mechanism, the control cabinet is arranged on one side of the rack, the welding mechanism comprises a lower seat, a lower supporting platform and an upper supporting platform, the lower supporting platform is arranged on the lower seat, the upper supporting platform and the lower supporting platform are in up-down arrangement, the upper supporting platform is connected with the pressurizing equipment through an insulating plate, the lower supporting platform is a cell body, a disc-type induction coil is arranged in the lower supporting platform, the lower end of the upper supporting platform is connected with an upper graphite platform while the upper end of the same is connected with a lower graphite platform, two graphite electric agglomerates are arranged between the upper graphite platform and the lower graphite platform, and a connecting member is put between the graphite electric agglomerates. The aluminum soft connection welder can realize uniform heating and is more accurate in temperature control.

Description

technical field [0001] The invention relates to the technical field of battery production equipment, in particular to an aluminum soft connection welding machine and a welding process. Background technique [0002] In recent years, as people pay more attention to issues such as air quality and the earth's oil resource crisis, pure electric vehicles, plug-in hybrid vehicles and other new energy vehicles that can achieve energy saving and emission reduction have developed rapidly, and power batteries have become hybrid vehicles. The performance of the key components on the car will directly affect the performance of the whole vehicle. From new energy cells to battery components, it is necessary to connect single-chip batteries to form a whole, which involves battery connectors, and then The welding of battery connectors has become a very important process. At present, in the welding and heating process of battery connectors, due to the slow heating speed and unstable temperatu...

[0002] In recent years, as people pay more attention to issues such as air quality and the earth's oil resource crisis, pure electric vehicles, plug-in hybrid vehicles and other new energy vehicles that can achieve energy saving and emission reduction have developed rapidly, and power batteries have become hybrid vehicles. The performance of the key components on the car will directly affect the performance of the whole vehicle. From new energy cells to battery components, it is necessary to connect single-chip batteries to form a whole, which involves battery connectors, and then The welding of battery connectors has become a very important process. At present, in the welding and heating process of battery connectors, due to the slow heating speed and unstable temperature, the materials in the later stage cannot be used up, the operation is inconvenient, the heating is uneven, and the graphite wears seriously. , and high cost
