Abstract

The invention discloses a die cutting and folding integrated machine, and relates to the technical field of lithium battery lamination. The integrated machine comprises a positive plate die cutting assembly, a negative plate die cutting assembly, an automatic roll changing and tape splicing assembly, a composite rolling assembly and a battery cell folding assembly; the positive plate die cutting assembly and the negative plate die cutting assembly are oppositely arranged at the two sides of the automatic roll changing and tape splicing assembly; the positive plate die cutting assembly is usedfor providing a positive plate formed through die cutting; the negative plate die cutting assembly is used for providing a negative plate formed through die cutting; the automatic roll changing and tape splicing assembly is used for providing a diaphragm; the composite rolling assembly is positioned between the positive plate die cutting assembly and the negative plate die cutting assembly, and isused for rolling the positive plate, the negative plate and the diaphragm; and the battery cell folding assembly is positioned under the composite rolling assembly. The die cutting and folding integrated machine has the beneficial effects of being ingenious in structure and high in lamination speed, and the production efficiency of lithium batteries is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery stacks, and more specifically, the invention relates to a die-cutting and folding machine. Background technique [0002] Lithium-ion battery is a new generation of green high-energy battery with excellent performance, and has become one of the focuses of high-tech development. Lithium-ion batteries have the following characteristics: high voltage, high capacity, low consumption, no memory effect, no pollution, small size, small internal resistance, less self-discharge, and more cycles. Because of the above-mentioned characteristics, lithium-ion batteries have been applied to many civilian and military fields such as mobile phones, notebook computers, video cameras, and digital cameras. [0003] The existing lamination equipment adopts the Z-type lamination method. The structure of the equipment is complex, the volume is large, and it is not convenient to place and transport. In addition, ...
