Description

technical field [0001] The invention belongs to the field of die-cutting, and relates to a circular die-cutting machine, in particular to a non-stop roll-changing die-cutting machine used for feeding and receiving lithium battery positive and negative base materials. Background technique [0002] The research and development and application of lithium batteries have become the leading products in the field of new energy, with wider application fields and huge demand. They are mainly used in mobile phones, miniaturized mobile power supplies, passenger cars (electric vehicles), and various types of non-polluting tractors , multi-purpose robots and other equipment. [0003] The existing lithium battery base material positive electrode (aluminum-based film lithium iron phosphonate) and negative electrode (copper-based film graphite) material "tab" forming and cutting process is generally produced by traditional intermittent punch-type metal molds. There are disadvantages such a...
