Abstract

The present disclosure provides an apparatus for discharging powder for a secondary battery, the apparatus comprising: a hopper having an accommodating space in which powder is accommodated and a discharge port through which the powder is discharged, a mesh plate disposed inside the hopper, and a vibration transmission unit transmitting vibrations to the mesh plate.

First claim

What is claimed is:

1 . An apparatus for discharging powder for a secondary battery, the apparatus comprising:
a hopper having an accommodating space in which powder is accommodated and a discharge port through which the powder is discharged; a mesh plate disposed inside the hopper; and a vibration transmission unit transmitting vibrations to the mesh plate.

2 . The apparatus of claim 1 , further comprising:
at least one guide member disposed in the accommodating space and guiding a moving direction of the powder, wherein the at least one guide member is in contact with the mesh plate to receive vibrations from the mesh plate.

3 . The apparatus of claim 2 , wherein the at least one guide member is disposed on both sides of the mesh plate.

4 . The apparatus of claim 2 , wherein the at least one guide member is fixed to the mesh plate.

5 . The apparatus of claim 2 , wherein the at least one guide member includes an inclined portion formed on an external surface thereof to allow the powder to slide.

6 . The apparatus of claim 2 , wherein the at least one guide member has a cone or truncated cone shape.

7 . The apparatus of claim 2 , wherein the at least one guide member includes stainless steel.

8 . The apparatus of claim 1 , wherein
the hopper includes a tapered portion having an inner diameter that gradually narrows, and the discharge port is disposed in a lower portion of the tapered portion.

9 . The apparatus of claim 8 , wherein the mesh plate is disposed inside the tapered portion.

10 . The apparatus of claim 8 , wherein the tapered portion is in contact with the vibration transmission unit.

11 . The apparatus of claim 10 , wherein
the tapered portion contacts the mesh plate, and the vibration transmission unit is disposed outside the hopper opposite to a position in which the mesh plate is disposed.

12 . The apparatus of claim 9 , wherein
the vibration transmission unit and the mesh plate are connected through a connection member, and the connection member penetrates through a portion of the hopper.

13 . The apparatus of claim 1 , further comprising a controller controlling driving of the vibration transmission unit.

14 . The apparatus of claim 13 , wherein the controller receives a measurement value from a measurement sensor measuring a weight of the powder accommodated in the hopper and operates the vibration transmission unit according to the measurement value.

15 . The apparatus of claim 1 , wherein a valve opened and closed is connected to the discharge port.

16 . The apparatus of claim 1 , wherein the mesh plate includes stainless steel.
