Technical field
The present invention relates to battery pole piece technical field, especially a kind of online shaping equipment of electrodes of lithium-ion batteries.
Background technology
In the rolling production of electrodes of lithium-ion batteries, pole piece is rolled down to design thickness, the pole piece quilt after battery assembling
Electrolyte immersion produces expansion, so as to cause pole piece cumulative volume to increase, ties up electrolysis liquid space, influences battery performance.Solves this
Individual problem has following scheme, first scheme, and pole piece does not expand after being soaked by electrolyte.Alternative plan, pole piece rolling thickness are small by one
Point, design size is expanded into by electrolyte immersion.Third program, pole piece rolling thickness is a little bit smaller, is allowed by heating, cooling procedure
Pole piece expands, and reaches design thickness, then is not just expanded by electrolyte immersion.
The first string is difficult to realize in actual production.Second scheme can solve expansion issues, but pole piece immersion is swollen
It is swollen to need the time, while reservoir quantity is also controlled, actual production control is complicated, difficulty is big.Third program it is workable, it is necessary to
Refrigerating work procedure is heated in increase together.The third scheme has two kinds of implementations, after (1) rolling winding, puts entire volume material into baking
In case, heating and thermal insulation.(2) pole piece directly will be sent into firing equipment after roll-in, and controls heating-up temperature and soaking time, afterwards
Winding.
The content of the invention
It is an object of the invention to provide a kind of online shaping equipment of electrodes of lithium-ion batteries, using after roll-in that pole piece is straight
Pick into firing equipment, by heating, being incubated, wind afterwards.Referred to as " the online setting process of battery pole piece ", it is above-mentioned to solve
The problem of being proposed in background technology.
To achieve the above object, the present invention provides following technical scheme：
A kind of online shaping equipment of electrodes of lithium-ion batteries, including battery pole piece rolling mill, sizing heater box, tension force isolation

Unreeling machine introduces proximally by battery pole piece, is entered through unreeling machine and buffer roll in sizing heater box, the sizing
Deflector roll is provided with inside heater box, deflector roll is driven by servomotor, sets tension force to isolate machine and winding in the left side of sizing heater box
Machine, deflector roll of the battery pole piece out of sizing heater box, which is drawn, to be passed on tension force isolation machine and winder.
As the further scheme of the present invention：The linear velocity of the battery milling train is equal with the linear velocity of servomotor.
As the further scheme of the present invention：Temperature sensor and temperature control are also equipped with inside the sizing heater box
System, temperature sensor are electrically connected in the control board in temperature control system.
Compared with prior art, beneficial effect of the present invention：
The online shaping equipment of this electrodes of lithium-ion batteries, the pole piece after roll-in, by heating, cooling down, size is steady after fluid injection
Set；Pole piece is directly sent into firing equipment after roll-in, heating and roll-in are completed simultaneously, and productivity ratio is high；Cooling procedure is in pole piece
Completed in winding, saved the investment of cooling device；Pole piece two sides is directly heated, and expansion is uniform, the uniformity of product is guaranteed；
Reduce material and carry required personnel, equipment, time.
