Abstract

The present invention relates to an electrode mounting unit comprising: a mounting member comprising a horizontal plate, a vertical plate disposed on a top surface of the horizontal plate, and a shaft which is fixed to the vertical plate and into which an electrode roll is fitted to be mounted; and an unwinding prevention member disposed between the electrode wound around the electrode roll and the horizontal plate to support the electrode wound around the electrode roll so as to prevent the electrode wound around the electrode roll from being unwound.

First claim

The invention claimed is:

1. An electrode mounting unit comprising:
a mounting member comprising a horizontal plate, a vertical plate disposed on a top surface of the horizontal plate, and a shaft which is fixed to the vertical plate and into which an electrode roll is fitted to be mounted; and
an unwinding prevention member disposed between an electrode wound around the electrode roll and the horizontal plate to support the electrode wound around the electrode roll so as to prevent the electrode wound around the electrode roll from being unwound.

2. The electrode mounting unit of claim 1 , wherein a top surface of the unwinding prevention member on which the electrode is supported is formed as a curved surface having the same curvature radius as the electrode wound around the electrode roll.

3. The electrode mounting unit of claim 2 , wherein a hook protrusion on which the electrode wound around the electrode roll is hooked and supported is formed on one end of the curved surface.

4. The electrode mounting unit of claim 1 , wherein one side surface of the unwinding prevention member is formed as an inclined surface.

5. The electrode mounting unit of claim 4 , wherein a handle part is formed on the other side surface of the unwinding prevention member.

6. The electrode mounting unit of claim 1 , wherein a bottom surface of the unwinding prevention member is formed as a horizontal surface,
wherein an unevenness for preventing sliding is formed on the horizontal surface.

7. The electrode mounting unit of claim 1 , wherein the unwinding prevention member is made of a synthetic resin having elastic restoring force.

8. The electrode mounting unit of claim 2 , wherein an unevenness is formed on the curved surface.

9. An electrode drying device comprising:
a mounting unit on which an electrode roll around which an electrode is wound is mounted; and
a drying chamber accommodating the mounting unit to dry the electrode wound around the electrode roll,
wherein the mounting unit comprises:
a mounting member comprising a horizontal plate, a vertical plate disposed on a top surface of the horizontal plate, and a shaft which is fixed to the vertical plate and into which the electrode roll is fitted to be mounted; and
an unwinding prevention member disposed between the electrode wound around the electrode roll and the horizontal plate to support the electrode wound around the electrode roll so as to prevent the electrode wound around the electrode roll from being unwound.

10. The electrode drying device of claim 9 , wherein a top surface of the unwinding prevention member on which the electrode is supported is formed as a curved surface having the same curvature radius as the electrode wound around the electrode roll.
