Abstract
The utility model, which essentially discloses one kind, prevents the corrugated winding mechanism of pole piece, including positive plate, membrane one, negative plate, the membrane two arranged successively, is synchronously wound after four layer materials overlapping；It is provided with every roller one, is provided between negative plate, membrane two every roller two between positive plate, membrane one.The utility model can increase the tension force of membrane, and membrane is paved support and is put down, prevents membrane from wrinkling, improves product quality.
Description
Technical field
Dynamic lithium battery production technical field is the utility model is related to, the corrugated winding mechanism of pole piece is especially prevented with one kind
It is related.
Background technology
In the production process of lithium ion battery, one of equipment often having is up- coiler, at present lithium ionic cell winding machine
All it is full automatic winding, using AC servo machinery driving, pole piece is sent in take-up roll by some rollers being laid on wallboard
Winding.
Lithium ion battery includes positive plate, negative plate, and positive/negative plate centre and both sides are both provided with membrane, and multilayer material exists
Overlapping one on final wireline reel, since membrane is macromolecule material film, quality is softer, during membranaceous sheet material winding, holds
Fold easily is played near the contact point of winding, causes to eventually form water ripples, makes film covering uneven, directly affects battery matter
Amount.
Therefore the present inventor is directed to this present situation, local improvement has been carried out in equipment, thus this case produces.
Utility model content
The purpose of this utility model, which is to provide one kind, prevents the corrugated winding mechanism of pole piece, can increase the tension force of membrane,
Membrane is paved support to put down, prevents membrane from wrinkling, improves product quality.
To achieve the above object, the technical solution adopted in the utility model is as follows：
One kind prevents the corrugated winding mechanism of pole piece, including positive plate, membrane one, negative plate, the membrane two arranged successively,
Synchronously wound after four layer materials overlapping；It is provided between positive plate, membrane one every roller one, is set between negative plate, membrane two
It is equipped with every roller two.
The positive plate and membrane one is distributed on one side, and negative plate and membrane two are distributed in other side.
The positive plate and one winding point opening degree of membrane are 40 ~ 60 °.
The negative plate and two winding point opening degree of membrane are 40 ~ 60 °.
The winding point every roller one or every two shaft core spacing of roller with being no more than 8cm.
The positive plate and negative plate winding point opening degree are not less than 90 °.
Described includes axis body and axle sleeve every roller one and every roller two, and axle sleeve is coated on axis body surface, is offered inside shaft core
Radial direction elongated slot, is cased with shaft core in elongated slot, and spring support is provided with shaft core and long poor gap between two ends.
After using the above scheme, the utility model positive/negative plate respectively every roller forced by one membrane winding of fitting, when winding
Distraction angle so that soft membrane at the last winding point near generate a larger tension force so that membrane flattens, whole
Neat is layered on pole piece, no setback corrugation.
Being set inside roller in the utility model has certain elasticity at the same time, can be with the flexible trim locations of dynamics.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model preferred embodiment；
Fig. 2 is the schematic cross-section of the utility model preferred embodiment interval roller.
Embodiment
Referring to Fig. 1 and Fig. 2, the utility model preferred embodiment is further elaborated.
The component being mainly concerned with the present embodiment has positive plate 1, membrane 1, negative plate 3, membrane 24.1 He of positive plate
Side, negative plate 3 and membrane 24 are distributed in opposite side to the distribution of membrane 1 wherein.Four layer materials are superimposed together during winding,
Wound on wind-up roll 5.Most important innovative point is in positive plate 1, membrane on winding point position in the present embodiment
Set between one 2 every roller 1, be provided with winding point position between negative plate 3 and membrane 24 every roller 27.Every roller
1 and every roller 27 setting so that membrane 1, the membrane 24 of soft material adds tension force, make its tiling neat, Ke Yijun
Even is attached on corresponding pole piece.
In order to reach relatively good effect, every roller 1 and after the setting of roller 27 so that positive plate and membrane one are wound
Point opening degree, and negative plate and two winding point opening degree of membrane are almost maintained at 40 ~ 60 °, and the distance away from winding point
It must not be too far away, be usually no more than 8cm.After can so causing membrane opening to pave, horse back docile is on pole piece.And this implementation
Angle in example between positive plate 1 and negative plate 3 also keeps being not less than 90 °
In order to allow every roller 1 and have certain elasticity and automatic adjustment property, this reality contacting pole piece and when membrane every roller 24
Apply in example includes axis body 81 and axle sleeve 82 every roller 1 and every roller 24, and axle sleeve 82 is elastomeric material, is tightly wrapped in axis body 81
Outer surface.The elongated slot 83 of radial direction is opened up in the centre of axis body 81, is interted among elongated slot 83 into shaft core 84, shaft core 84 is in long grain
Spring 85 is installed in 83 gap between two ends.
When being contacted every the positive plates 1 of one 6 both sides of roller, membrane 1 every roller 1, axis body 81 by spring 85 elastic force from
It is dynamic to be fine-tuning to suitable position.
Above is the utility model preferred embodiment, make that some other are simple under the utility model concept thereof
Replace and change, should all be considered as belonging to the protection category of the utility model.
