Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a separator cutter brushing apparatus for a secondary battery winding system,

In order to prevent the material coated on the surface of the separator from being scattered and accumulated on the cutter blade when the separator is cut and wound in a certain length in the process of winding the secondary battery, And more particularly, to a separator cutter brushing apparatus for a secondary battery winding system for removing a separation coating material from a separation membrane cutting process of a secondary battery winding system.

Generally, lithium ion batteries have many advantages over other batteries. However, since the reactivity of lithium is so high that it is difficult to solve the stability problem, it has not been commercialized, and it has been commercialized recently.

Advantages of lithium ion batteries include:

First, lithium metal is much lighter than any other metal, so its energy density is very high. Secondly, its electromotive force is great. Third, there is no memory effect (battery has to be completely discharged before charging) And the power loss due to the fourth self discharge is very small.

The lithium ion secondary battery having such advantages is a high voltage battery having stability because it can be rapidly charged due to the intercalation reaction of lithium ions, in which the charging reaction of the negative electrode is comparatively fast, and is present in the state of lithium ion. Is widely used in portable electronic devices such as mobile phones and notebook computers because of its large size and miniaturization, and is being used in batteries of electric vehicles in recent years.

Lithium-ion secondary batteries used in batteries for electric vehicles are manufactured by applying a cathode and an anode active material to a metal foil (Al or Cu foil) to manufacture an anode and a cathode, (JELLY ROLL), which is manufactured by inserting and winding the jelly roll into a cylindrical or rectangular metal container, filling the jelly roll with the electrolyte, and sealing the jelly roll.

The manufacturing process of the lithium ion secondary battery can be divided into an electrode manufacturing process and an assembling process. Here, the electrode manufacturing process is divided into stirring, coating, drying, and compression cutting (slitting) Insertion, electrolyte injection, and encapsulation.

The characteristics of the lithium ion secondary battery are very different depending on the state of the positive electrode and the negative electrode, the lamination method, and the winding method. The applicant of the present invention, through Korean Patent Registration No. 10-1359430, A jelly roll production system and a jelly roll production method in which a jelly roll is manufactured by winding.

As described above, in the system including the electrode winding process of the secondary battery as in the jellyroll production system,

The separator is cut using a cutting blade in accordance with the winding length.

Here, the surface of the separator is coated with a ceramic. When the cutting blade cuts through the ceramic-coated separator, the ceramic powder is blown.

More specifically, in the winding process of the jelly roll, the electrodes are firstly supplied in a predetermined length, and then the separator is supplied and then completed with a jelly roll. In the cutting process of the separator, the coating material and foreign matter scattered in the electrode are scattered, When cutting is performed, ceramic powder is blown as described above, so that when a cutting process is repeatedly performed, a large amount of ceramic powder is accumulated in the peripheral machine parts.

Particularly, it is difficult to form a pedestal by the back side of the separator due to the winding structure of a winding machine in which a positive electrode plate and a negative electrode plate are inserted and a separator is inserted. Thus, the separator is cut by a blade in the space, Foreign matters and ceramic powders may be scattered more severely.

In this way, ceramic powder and foreign matter are continuously accumulated on the cutter, and as a result, the membrane cutting is not smoothly performed.

Particularly, the cutter blade of the separation membrane is formed in a sawtooth shape in order to more effectively cut the separation membrane. When the ceramic foreign matter is piled up as shown in FIG. 1, the separation membrane is not cut.

1 is a photograph showing a state in which a ceramic coating material is fixed to a cutter blade.

Therefore, since the separation of the membrane is not smoothly performed, there is a high probability that a malfunction of the winding device occurs, and it is necessary to disassemble and clean the relevant part frequently, thereby causing a deterioration in productivity.

In the present invention, in a secondary battery manufacturing system for manufacturing a battery roll by winding a separator of a secondary battery coated with a separate material such as ceramic on a surface thereof, the coating material separated from the separator during the cutting process is not fixed to the cutter blade To a brushing device for removing the brush.

The present invention can cut a separator when a separator is cut to have a predetermined length for winding an electrode roll so that the separator can be removed when the separator is cut and the coating material on the separator surface is buried in the cutter blade. And the cutter blade can be wiped off after the cut is made.

According to the present invention, there is provided a separation cutter brushing apparatus for a secondary battery winding system,

A separator cutter brushing device for a secondary battery winding system comprising a battery roll winding device for supplying a positive electrode and a negative electrode cut to a predetermined length and cutting the separator to a predetermined length to manufacture a battery roll,

And a brush module moving means for moving the brush module to contact the blade portion and rotating the brush to wipe the blade portion.

According to the present invention, since the cutter blade is wiped off each time the separator is cut, the problem caused by the ceramic powder as the coating material can be solved, and productivity can be improved and it is advantageous for maintenance of equipment.
