Abstract
It the utility model is related to a kind of cleaning device for electrodes of lithium-ion batteries.Including the support on base, described support is provided with crosses roller and the gas tank being arranged on above roller for what pole piece passed through, and the bottom of the gas tank is provided with multiple injection holes symmetrically arranged, the gas that the injection hole sprays points to pole piece.As shown from the above technical solution, the utility model is cleaned by injection hole to pollutants such as the dust of pole piece, while avoids pole piece from being crumpled caused by injection, farthest ensure that the cleannes of pole piece.
Description
Technical field
It the utility model is related to a kind of cleaning device for electrodes of lithium-ion batteries of lithium ion battery.
Background technology
The both positive and negative polarity pole piece of lithium ion battery is by positive and negative pole material by way of coating, uniformly coated in collector
On, and pass through the compacted density of pole piece roll-in raising battery.Pole piece is likely to occur after coating baking process and roll-in
The pollutants such as dust.The dust of pole piece, which may cause barrier film to pierce through, causes battery short circuit, reduces the yields of battery manufacture,
Increase production cost, while there is also larger potential safety hazard for product.
Utility model content
The purpose of this utility model is to provide a kind of cleaning device for electrodes of lithium-ion batteries, and the cleaning device can
Farthest to ensure the cleannes of pole piece.
To achieve the above object, the utility model employs following technical scheme：Including the support on base, institute
The support stated is provided with crosses roller and the gas tank being arranged on above roller for what pole piece passed through, and the bottom of the gas tank is provided with multiple
The injection hole symmetrically arranged, the gas that the injection hole sprays point to pole piece.
The direction that the injection hole sprays gas is opposite with the direction of motion of pole piece.
Described gas tank is connected with the supply air line of outside, and described supply air line is provided with pressure regulator valve and pressure gauge.
The gas that the injection hole sprays is compressed air, and the pressure of compressed air is 0.1~0.2MPa.
The angle of described injection hole and gas tank horizontal plane is 60 °~75 °.
The angle of described injection hole and gas tank vertical plane is 45 °~60 °.
As shown from the above technical solution, the utility model is carried out clear by injection hole to pollutants such as the dust of pole piece
It is clean, while avoid pole piece from being crumpled caused by injection, it farthest ensure that the cleannes of pole piece.
Brief description of the drawings
Fig. 1 is front view of the present utility model；
Fig. 2 is Fig. 1 left view.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings：
A kind of cleaning device for electrodes of lithium-ion batteries as shown in Figure 1, including the support 2 on base 1,
Support 2 is provided with the gas tank 5 crossed roller 4 and be arranged on the top of roller 4 passed through for pole piece 3, and the bottom of gas tank 5 is provided with multiple equal
The even injection hole 6 being arranged symmetrically, the gas that injection hole 6 sprays point to the surface of pole piece 3.Preferably, injection hole 6 is in left and right directions mirror
As arrangement.
Further, gas tank 5 is connected with the supply air line of outside, and supply air line is provided with pressure regulator valve 7 and pressure gauge 8.
Further, injection hole 6 sprays the direction of gas with the direction of motion of pole piece 3 on the contrary, further, injection hole
6 gases sprayed are compressed air, and the pressure of compressed air is 0.1~0.2MPa.
Further, the angle theta of injection hole 6 and the horizontal plane of gas tank 5 is 60 °~75 °.
Further, the angle α of injection hole 6 and the vertical plane of gas tank 5 is 45 °~60 °.
The direction of motion of pole piece 3 and the blowing direction of injection hole 6 are on the contrary, jetting pressure is adjusted in 0.1~0.2 MPa scopes
It is interior, the pollutant on the surface of pole piece 3 can be not only cleaned, phenomena such as also avoiding causing pole piece 3 to be crumpled because jetting pressure is excessive.Injection
Hole 6 causes pollutant not to be re-attached to the surface of pole piece 3 with the angle theta of the horizontal plane of gas tank 5 and the angle α of vertical plane, maximum
The cleannes on the surface of guarantee pole piece 3.
Operation principle of the present utility model is as follows：
For pole piece 3 before coating baking or roll-in winding, pole piece controls compressed air by cleaning device, regulation pressure regulator valve 7
Pressure in 0.1 ~ 0.2mpa, ensure that the pollutants such as the dust of pole piece are effectively cleaned, while avoid pole piece because of injection
Cause to crumple, the angle of injection hole and gas tank and pole piece winding are in opposite direction, ensure that the pollutants such as dust will not adhere to again.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to this practicality
New scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are to this
The various modifications and improvement that the technical scheme of utility model is made, the protection of the utility model claims book determination all should be fallen into
In the range of.
