Description
Technical field
The utility model is related to field of battery production more particularly to a kind of benefit lithium devices.
Background technology
With the development of modern society, various intelligence equipments (mobile phone, laptop, tablet, electric vehicle etc.) there has been
It is widely applied.At the same time, demand of the client to heavy-duty battery is also increasingly stronger.Lithium ion battery is due to energy density
The advantages such as height, service life length, green non-pollution, security performance are widely used in consumer electronics product and electric vehicle neck
Domain.In terms of lithium battery energy density is improved, lithium technique is mended as one of key technology.
Existing benefit lithium technique generally includes two ways：The first is first to roll lithium band onto transfer membrane, Ran Houzai
Lithium band on transfer membrane is laminating to pole piece；Second is that releasing agent is directly coated on transferring roller, then arrives the calendering of lithium band
On transferring roller, transferring roller is laminating to pole piece by lithium band again.But in the first scheme, transfer membrane is typically only capable to be intended for single use,
The cost of consuming is high；Meanwhile transfer membrane needs to draw, is transferred to laminating equipment, occupies larger space, and causes to mend lithium work
Skill is complicated.In second scheme, (within 5 μm) high to releasing agent coating thickness coherence request, and transferring roller table itself
Just there is bounce (2 μm) in face, causes coating precision poor, easily influences lithium band rolling effect, often appearance calendering uneven thickness, pressure
It is difficult to control to prolong appearance, it is difficult to accomplish consecutive production.
Utility model content
In view of the problem of background technology, the purpose of this utility model is to provide a kind of benefit lithium devices, can drop
Low cost ensures rolling effect, realizes consecutive production.
To achieve these goals, the utility model provides a kind of benefit lithium device, is conveyed including roller press mechanism, lithium band
Mechanism, substrate conveying mechanism and coating mechanism.Roller press mechanism includes the first roller, the second roller and the third roller that are sequentially arranged
Wheel.Lithium band conveying mechanism is used to lithium band being sent between the first roller and the second roller；Substrate conveying mechanism is used to send base material
Enter between the second roller and third roller.
Coating mechanism includes the first applicator roll and first material slot；Releasing agent, and the first object are contained in first material slot
Releasing agent in hopper is transferred to the roll surface of the first applicator roll during the first applicator roll rotates；The roll surface of first applicator roll
It is contacted with the surface of lithium band towards the second roller, and the releasing agent on the roll surface of the first applicator roll is coated to lithium band at the time of contact
Surface.
First roller and the second roller are used to carry out the lithium band for being coated with releasing agent roll-in, and the lithium band attachment after roll-in
In the second roller；Second roller and third roller are used for lithium band and base material progress roll-in to being attached to the second roller, and roll-in
Lithium band is attached to base material afterwards.
The beneficial effects of the utility model are as follows：
When needing to carry out benefit lithium to base material, lithium band setting to lithium band conveying mechanism conveys base material setting to base material
Mechanism；Lithium band conveying mechanism drives lithium band to advance to and roll-in is carried out between the first roller and the second roller, substrate conveying mechanism band
Dynamic base material, which advances to, carries out roll-in between the second roller and third roller.
Lithium band can pass through the first applicator roll during tape transport, and have releasing agent on the roll surface of the first applicator roll, because
This, when lithium band contacts friction with the roll surface of the first applicator roll towards the surface of the second roller, on the roll surface of the first applicator roll
Releasing agent is transferred to lithium band towards the surface of the second roller.When lithium is brought between the first roller and the second roller, lithium band
By roll-in and it is attached on the second roller.With the rotation of the second roller, lithium band and the base material being attached on the second roller connect
It touches, and is attached on base material under the roll-in of the second roller and third roller.Since releasing agent can reduce lithium band and the second roller
Adhesion strength between wheel, therefore, when gap of the base material between the second roller and third roller is pierced by, lithium band can be in base material
It is removed from the second roller under traction, so as to fulfill the benefit lithium of base material.
Since the lithium band after calendering is directly attached to the second roller, and utilize releasing agent by the benefit lithium device of the utility model
It is laminating on base material directly by lithium band with the second roller, without transfer membrane of the prior art, so as to reduce production cost, simplify
Mend lithium technique.Simultaneously as lithium band, after the roll-in of the first roller and the second roller, thickness is rolled by grade to micron
Grade, therefore the weight of releasing agent is also easy to control, even if the weight of releasing agent coating is larger, releasing agent can also roll in lithium band
Small weight, small thickness are gradually become by high weight, high thickness automatically in the process, so as to be uniformly coated on lithium belt surface.Therefore,
Compared with releasing agent is coated to the scheme of transferring roller in the prior art, the benefit lithium device of the utility model can be controlled preferably
Appearance after lithium band and base material calendering processed, can realize consecutive production.
