5V20A 64 Channel Negative Pressure Formation Machine For Prismatic Battery Production
1. Device functions
1. Equipment function: the equipment is mainly used for lithium-ion prismatic batteries formation at high temperature(30-50ºC),negative pressure(-10--95),It can quickly activate the battery formation performance at high temperature, vacuum extract the air in the battery formation, shorten the formation time and shorten the battery production cycle.
2. The equipment consists of a set of chemical power cabinet (5V20A, 64 points), 8 sets of needle bed fixture groups (8 points / set) and a set of negative pressure vacuum system (4 layers, 2 pipes with a diameter of 32mm in each layer, divided into 64 points, each single pipe with a diameter of 8mm, fluororubber anti-corrosion sucker); (the power supply and fixture are placed separately).
3. Workflow description:
The rail lift car sends the fixture group → pushes the fixture group into the needle bed → starts the needle bed → starts the negative pressure process and charges the formation → the formation is completed → automatically opens the needle bed fixture → the rail lift car manually withdraws the fixture group → the next round of fixture group charging formation
