Description
technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a winding machine for producing paired bare cells. Background technique [0002] With the rapid increase of my country's car ownership, it has caused a serious burden on oil consumption, and the large-scale use of oil is the root cause of greenhouse gas emissions, global warming, serious environmental pollution, and air smog. Since 2010, the Chinese government has begun to support the new energy vehicle industry. The development of new energy vehicles is inseparable from power batteries. As one of the core components, the cost of power batteries accounts for 30% to 50% of the cost of a complete vehicle. The high price of electric vehicles is significantly higher than that of fuel vehicles of the same level, and further reducing battery costs is the direction of the industry's efforts. [0003] Power battery hard shell cells are usually paired and welded togeth...
