With.Meanwhile to promote production capacity, most battery producers are during pole piece coats, using the technique of several continuous stripe-coatings
Mode.
The pole piece of more stripe-coatings is left white area due to existing between dressing area, in higher roll-in compacted density,
Pole piece dressing area from be left white area since elongation percentage is different, centre, which is left white area, can generate buckling phenomena.One is cut in traditional roll-in
Most of machine is only concerned the variation of the pole piece tension in production process, and this equipment is small for material compacted density and without the pole being left white
Piece coating processes applicability is preferable, but is difficult the technique for meeting high-pressure solid, the material of high-energy density and more stripe-coatings.Separately
Outside, since there are a certain distance, traditional tension and correction controls to be difficult to ensure pole piece between roll-in system and splitting system
Region is left white in production process will not generate secondary buckling phenomena.
Utility model content
To solve technical problem present in background technique, the utility model proposes a kind of lithium battery rollers of anti-pole piece fold
Press cutting integrated machine.

Between setting, the first tension roller mechanism is connected in the first driving mechanism, and the first tension roller mechanism acts on the tension direction of pole piece
Towards unwinding device；Second tension roller mechanism is arranged between home roll device and splitting winding device, and the second tension roller mechanism connects
It connects in the second driving mechanism, the second tension roller mechanism acts on the tension direction of pole piece towards splitting winding device.
It preferably, further include deflector roll driving device, deflector roll driving device is located at the second tension roller mechanism and splitting winding dress
Between setting.
Preferably, deflector roll driving device includes guide roller and third driving mechanism, and guide roller is connected to third driving mechanism
On.
In the utility model, the lithium battery roll-in cutting integrated machine of the anti-pole piece fold proposed, in home roll device to pole
During piece carries out roll-in, pole piece is carried out biaxial tension by the first tension roller mechanism and the second tension roller mechanism, so that in roller
Pole piece during pressure is in tight state, avoid pole piece material area and pole piece be left white area because elongation percentage difference due to make pole piece roll-in after
Generate fold.
Detailed description of the invention
