A kind of intelligently cross cutting winding integrated machine and its workflow
Technical field
The invention belongs to lithium battery production equipment technical fields, and in particular to a kind of intelligently cross cutting winding integrated machine and its work
Make flow.
Background technology
Currently, in lithium-ion-power cell production field, the technique mainly used has lamination process and winding process, winding
Technique is divided into multipole ear winding and is wound with full lug.Lamination process is mainly used for soft pack cell, has energy density height, is manufactured into
This low advantage, but its lamination speed is slow, poor safety performance, and overall application is not yet received in power battery field;Winding process
Be mainly used for cylindrical electrical core and square electric cell, have winding speed fast, the features such as security performance is high, and monomer capacity is big, gradually at
For industry prevailing technology.Full lug winding process is mainly used for cylindrical electrical core and the few square electric cell of windings, has winding
Speed is fast, the advantage adaptable to material, but big to the battery core assembly difficulty more than windings;Multi pole ears winding process is main
For square electric cell, to the adaptable of the electric core winding number of turns, security performance is high, is increasingly becoming the mainstream in market.
In multi pole ears winding process, in the prior art, lug cross cutting and pole piece coiling separate machined first use hardware knife
Mould carries out lug cross cutting to the pole piece after cold pressing, then the pole piece after cross cutting is wound with isolation film.The way generally requires
Lug line space design is carried out according to roll circumference, then designed size is input to die-cutting machine and is die cut, is carried out after cross cutting
Paper.If paper is unsuccessful, need to adjust lug spacing according to lug magnitude of misalignment;If paper success, can the amount of progress
Production.This method major drawbacks are as follows:
1, hardware cutting die manufacture maintenance cost is high, there is certain limitation, and not easy-to-replaceable to the variation range of lug spacing, wastes
Foil;
2, lug is die cut using hardware cutting die, cross cutting quality is uncontrollable, and jagged, picking equivalent risk needs positioning maintenance, process
Sampling observation, wastes a large amount of manpower and materials;
3, material cycling is carried out in cross cutting and winding intermediate demand, increases manpower demand, multiple change of lap tape splicing causes material
Waste;
4, in process of production, since die cutting procedure is the front end of rolling step, the lug spacing dimension of pole piece is
It is die cut in advance.But be die cut size and do not account for pole piece thickness to winding the influence of lug degree of registration, therefore cause winding
Process, the perimeter that operator must not infrequently adjust volume needle misplace come the lug get well, reduce equipment utilization rate and
Product is caused largely to waste;Meanwhile intangibly improving competency profiling of the winding apparatus to personnel;
5, lug dislocation is big, high to material coherence request, even if paper success, during volume production, and the difference of material thickness
It can still result in lug dislocation(By taking 40 circle of winding as an example, as material thickness difference 1um, lug magnitude of misalignment is up to 4mm), influence naked
The assembly of battery core back segment process and welding conveyance capacity;
6, designer is required it is high, designer must very familiar lug spacing design a model;
The prior art is unfavorable for the long term growth of enterprise, and the relevant technologies urgently optimize.
