Abstract
The invention relates to a cutting method of pole pieces of a lithium-ion power battery, which is characterized in that the pole pieces of the lithium-ion power battery are cut by lasers. The laser cutting method comprises the following steps: the pole pieces to be cut are transported to a cutting workpiece workbench by a feeding servo mechanism, the laser beams in a cantilever type laser system are aligned with the cutting positions of the pole pieces to be cut, the cantilever type laser system is controlled by industrial control computer software in a computer to cut the pole pieces in a non-contact manner and then the cut pole pieces pass through a material receiving machine of a piece brushing machine to enter the next piece brushing process. The pole pieces cut by the method of the invention have narrow cutting seams and smooth cut, and are uniform. Besides, because of cutting by fusing and gasifying, the pole pieces are free of burrs, cracks and stripping, and the powder on the pole pieces can not fall off. The cutting method of the invention features quick cutting speed, low cost and good pole piece quality, and ensures the yield to reach 100%, therefore, the performance of the lithium-ion power battery is improved and the life is prolonged.
Description
Technical field
The present invention relates to a kind of cutting method of lithium ion power cell pole flakes, it is the various hybrid automobiles of power source and pure electric automobile etc. that the lithium-ion-power cell that the present invention relates to is mainly used in the lithium-ion-power cell, belongs to the electrokinetic cell field.
Background technology
Lithium-ion-power cell mainly contains two kinds, and a kind of is the coiled lithium ion electrokinetic cell, and a kind of is the laminated Li-ion electrokinetic cell.Conventional method to the lithium ion power cell pole flakes cutting is at present: the cutting method of coiled lithium ion pole piece of power battery is to adopt banding machine by kerf cutter cutting pole piece, the cutting method of laminated Li-ion pole piece of power battery is to adopt the precision die punching press, suppresses or rolls the mould rolling and cut pole piece with cutting die.The cutting method of above-mentioned these traditional lithium ion power cell pole flakes all is to adopt the machine cuts method, utilize sharp blade that pole piece is cut off by force, so the pole piece that said method cuts out has following defective: the pole piece that cuts out is inhomogeneous, have burr on the pole piece, and the powder on the pole piece drops easily, simultaneously because blade makes pole piece edge generation slight crack with the mechanical stress that pole piece cuts off generation by force, the part area of pole piece produces slurry and warps and fractures, even peel off, this has seriously influenced the electrical property of lithium-ion-power cell, can cause battery drain, the generation of phenomenons such as self discharge, sometimes the burr at pole piece edge can puncture barrier film and make the positive/negative plate short circuit cause the damage of entire cell, even hidden short circuit leaky in manufacture process, temporarily do not occur, but after lithium-ion-power cell recycles a period of time, the reaction capacity of lithium-ion-power cell diminishes, make each cell capacity of tandem compound inconsistent, thereby make the one-tenth Battery pack matched because cell capacity serious discrete and unbalance, make into Battery pack because of the damaging the service life that shortens into Battery pack ahead of time of cell, cause the significant wastage of the energy and the increase of cost.And the yield rate of the cutting method of existing lithium ion power cell pole flakes cutting pole piece is very low, has caused the increase of cutting pole piece cost, has also increased the waste of labor intensity of operating personnel and pole piece greatly.
Summary of the invention
The cutting method that the purpose of this invention is to provide a kind of lithium ion power cell pole flakes, the pole piece quality that this method is simple, cutting speed is fast, efficient is high, cut out is good, cost is low.
The technical scheme that realizes above-mentioned purpose is: a kind of cutting method of lithium ion power cell pole flakes, lithium ion power cell pole flakes is cut by laser cutting method.
Described in the present invention laser cutting method step is: pole piece to be cut is delivered on the cut workpiece workbench by the feeding servounit, laser beam in the cantilevered laser system is aimed at the cutting position of pole piece to be cut, by the industrial control computer software control cantilevered laser system in the computer, with the untouchable cut-out of pole piece, the pole piece that cuts then enters down by brushing machine rewinding machinery and brushes the sheet operation together.
After adopting technique scheme, have a lot of benefits: the present invention changes the machine cuts method of traditional lithium ion power cell pole flakes, adopt the method for laser cutting pole piece, cutting appliance is contactless cutting with the pole piece that is cut during cutting, the damage that traditional machine cuts method is brought to pole piece can not appear, the joint-cutting of cutting pole piece is narrow, otch is smooth, the pole piece that cuts out is even, and owing to be fusing gasification cutting, thereby not having burr on the pole piece, the powder on the pole piece can not drop, slight crack can not appear, peeling phenomenon, cutting speed of the present invention is fast, and cost is low, and the pole piece quality is good, and the clinkerings such as lithium powder that can make the pole piece edge when adopting the inventive method cutting are on positive/negative plate materials such as the aluminium foil of positive/negative plate and Copper Foil, the yield rate height that makes the pole piece cutting, yield rate reaches 100%, and the performance of lithium-ion-power cell is improved greatly, prolong the service life of lithium-ion-power cell greatly, and use cost reduces widely.The inventive method cutting pole piece labor intensity of operating staff is low.
The specific embodiment
The present invention is further detailed explanation below in conjunction with embodiment.
Process equipment: feeding servounit, cantilevered laser system, industrial control computer software, brushing machine rewinding machinery etc.
A kind of cutting method of lithium ion power cell pole flakes, pole piece to be cut is delivered on the cut workpiece workbench by the feeding servounit, laser beam in the cantilevered laser system is aimed at the cutting position of pole piece to be cut, by the industrial control computer software control cantilevered laser system in the computer, with the untouchable cut-out of pole piece, the pole piece that cuts then enters down by brushing machine rewinding machinery and brushes the sheet operation together.
Claims (2)
1, a kind of cutting method of lithium ion power cell pole flakes is characterized in that: lithium ion power cell pole flakes is cut by laser cutting method.
2, the cutting method of lithium ion power cell pole flakes according to claim 1, it is characterized in that: described laser cutting method step is: pole piece to be cut is delivered on the cut workpiece workbench by the feeding servounit, laser beam in the cantilevered laser system is aimed at the cutting position of pole piece to be cut, by the industrial control computer software control cantilevered laser system in the computer, with the untouchable cut-out of pole piece, the pole piece that cuts then enters down by brushing machine rewinding machinery and brushes the sheet operation together.
