Layer insulation gummed paper.It is currently that individually patch insulation gummed paper is carried out after big volume pole piece is cut into small pieces.Because of pole piece after cutting
Dimensional problem pastes insulating paper in small on piece, it is easy to generate insulation gummed paper or be longer than small pieces battery core length and cause to waste, want
It is shorter than small pieces battery core length and generates safety issue.
Summary of the invention
In view of the deficiency of the prior art, the object of the present invention is to provide a kind of lithium battery sheets to paste insulation gummed paper
Method, with reduce insulation gummed paper waste and guarantee security performance.
To achieve the above object, the technical solution adopted by the present invention is that: the method for lithium battery sheet patch insulation gummed paper, it is special
Sign is, after pole piece is made on pelleter, directly carries out patch insulating cement in the front of manufactured large stretch of pole piece, reverse side
Paper guarantees that large stretch of pole piece corresponding surface is completely covered in insulating cement paper size, then will post large stretch of cutting established practice of insulation gummed paper again
The small pieces of set pattern lattice.
Preferably, the detailed process of above-mentioned patch insulation gummed paper are as follows: S1: the large stretch of pole piece come out from pelleter is first using pressure
Contracting inert gas carries out surface purging；S2: patch insulation gummed paper region, the row of the direction of travel for the gummed paper that insulate and large stretch of pole piece are sent into
It walks that direction is opposite and insulation gummed paper is located above large stretch of pole piece, has briquetting during fitting in insulation gummed paper and sheet pole piece
Pressing is on insulating paper and briquetting is followed by insulation gummed paper movement, exhausted on pole piece by being adhered under the action of briquetting
The leveling of edge paper compresses, until completing the patch insulation gummed paper work of one side；S3: overturning large stretch of pole piece, similarly, guarantees insulating cement
The direction of travel of paper is opposite with large stretch of direction of travel of pole piece, has briquetting during fitting in insulation gummed paper and sheet pole piece
Pressing is on insulating paper and briquetting is followed by insulation gummed paper movement, exhausted on pole piece by being adhered under the action of briquetting
The leveling of edge paper compresses, and completes the patch insulation gummed paper work of another side.
Preferably, above-mentioned sheet cuts into the detailed process of small pieces are as follows: completes the big of tow sides patch insulation gummed paper work
Piece, send to cutting area, is die cut with the die cutter being adapted with small pieces specification by vertical feed right above sheet, cross cutting it is suitable
Sequence send to hot pressing area the hot pressing shaping at 30-40 DEG C in the small pieces obtained by cross cutting according to from left to right, from front to back.
Preferably, the large stretch of pole piece surrounding size 1-3cm of insulation gummed paper surrounding size.
Compared with prior art, the beneficial effect that the present invention has is: by means of the present invention, compared to small pieces patch insulation
The mode of gummed paper, can effectively save insulation gummed paper dosage (about 5-8%), and insulate gummed paper be bonded with pole piece it is close, smooth, hold
Long, the security performance of product is improved.
