Shutdown reel-changing type round-press-round die cutting machine for lithium battery positive and negative substrate unwinding and winding

Abstract

The invention relates to a shutdown reel-changing type round-press-round die cutting machine for lithium battery positive and negative substrate unwinding and winding. The shutdown reel-changing typeround-press-round die cutting machine is characterized by comprising a rack, an unwinding shaft, a receiving mechanism, a tension adjuster, an advancing deviation correction device, traction mechanisms, die cutting mechanisms, a split dust removing mechanism, a combined dust removing mechanism, a winding shaft and a central control box; the rack is sequentially provided with the unwinding shaft, the receiving mechanism, the tension adjuster, the advancing deviation correction device, the traction mechanism, the die cutting mechanism, the traction mechanism, the tension adjuster and the windingshaft from left to right; and the split dust removing mechanism is arranged on the receiving mechanism, the combined dust removing mechanism is arranged on the traction mechanism behind the die cutting mechanism and the die cutting mechanism, and the central control box is hoisted at the front end of the rack through an installing frame. The shutdown reel-changing type round-press-round die cutting machine has the advantages of improving the machining efficiency, being convenient to operate, reducing the cost, ensuring the product quality, meeting the client requirement and being easy to achieve.

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 shut-down roll-changing circular die-cutting machine used for charging and rewinding lithium battery positive and negative substrates. Background technique [0002] The research and development and application of lithium batteries have become the leading products in the field of new energy. The application fields are more extensive and the demand is huge. They are mainly used in mobile phones, miniaturized mobile power supplies, passenger vehicles (electric vehicles), and various pollution-free tractors. , Multi-purpose robots and other equipment. [0003] Existing lithium battery substrate positive electrode (aluminum-based film lithium iron phosphate) and negative electrode (copper-based film graphite) material "tab" forming and cutting processes are generally produced by traditional intermittent punch-type hardware molds. There are disadvan...

AI Technical Summary

Problems solved by technology

There are disadvantages such as slow running speed, low production efficiency, cumbersome adjustment and maintenance of abrasive tools, long production cycle, and high cost of a single mold. At the same time, the intermittent buffer feeding method also has a certain degree of influence on the coating density and surface quality of the substrate. It has a bottleneck effect on the improvement of lithium battery production efficiency, potential hidden dangers to the stability of energy storage index parameters, and serious constraints on product specification expansion, capacity improvement, and realization of comprehensive benefits.
