Abstract

The present invention relates to an apparatus and a method for manufacturing a channel plate, and according to one aspect of the present invention, there is provided an apparatus for manufacturing a channel plate, which is a manufacturing apparatus for forming a channel for transferring a substance to a plate, comprising a slitting unit provided to have a predetermined pattern for forming a plurality of openings on the plate in a transport process of the plate and a pressing unit provided to form a channel on the plate by pressurizing the opening region of the plate passing through the punching unit to bend it in a predetermined angle and direction.

First claim

The invention claimed is:

1. An apparatus for manufacturing a channel plate, which is a manufacturing apparatus for forming a channel for transferring a substance to a plate, comprising:
a pair of first rollers disposed to allow passage of the plate, and provided with a raised pattern on an outer circumferential surface of each roller of the pair of first rollers to form a plurality of openings on the plate in a transport process of said plate; and
a pair of second rollers disposed to allow passage of the plate and provided to form a channel on the plate by pressurizing a region of the plate having the plurality of openings passing through the pair of second rollers to bend the plate in a predetermined angle and direction,
wherein at least one roller of the second pair of rollers has a raised pattern on an outer circumferential surface.

2. The apparatus for manufacturing a channel plate according to claim 1 , wherein the raised patterns of the pair of first rollers are provided so as to have a same length, width, and thickness.

3. The apparatus for manufacturing a channel plate according to claim 1 , wherein the raised patterns of the pair of first rollers are provided so that at least one of a length, width, and thickness of the raised patterns is different from each other.

4. The apparatus for manufacturing a channel plate according to claim 1 , wherein the pair of first rollers has a same structure, and
wherein the raised pattern of an upper roller of the pair of first rollers and the raised pattern of a lower roller of the pair of first rollers, which contact a specific point of the plate, are provided to be the same.

5. The apparatus for manufacturing a channel plate according to claim 1 , wherein the pair of second rollers has a same raised pattern as the first pair of rollers, and
wherein the raised pattern of an upper roller of the pair of second rollers and the raised pattern of a lower roller of the pair of second rollers, which contact a specific point of the plate, are the same.

6. The apparatus for manufacturing a channel plate according to claim 1 , wherein rollers of the pair of second rollers have different raised patterns from each other, and
wherein the raised pattern of an upper roller of the pair of second rollers and the raised pattern of a lower roller of the pair of second rollers, which contact a specific point of the plate, are different.

7. The apparatus for manufacturing a channel plate according to claim 1 , wherein a first roller of the pair of second rollers has a plurality of raised patterns on the outer circumferential surface, and
wherein a second roller of the pair of second rollers has no raised pattern on the outer circumferential surface.

8. The apparatus for manufacturing a channel plate according to claim 1 , wherein the channel plate is a separating plate for a fuel cell.

9. The apparatus for manufacturing a channel plate according to claim 1 , further comprising a plurality of transport rolls for transporting the plate.

10. The apparatus for manufacturing a channel plate according to claim 1 , further comprising a pair of third rollers pressurizing the region of the plate having the plurality of openings,
wherein the pair of third rollers has one or more stepped portions along the direction of the rotational axis.

11. The apparatus for manufacturing a channel plate according to claim 10 , further comprising a rolling unit for rolling the plate passing through the second pair of rollers.

12. The apparatus for manufacturing a channel plate according to claim 11 , wherein the rolling unit comprises a fourth pair of rollers.

13. The apparatus for manufacturing a channel plate according to claim 10 , wherein the pair of third rollers is provided so that a diameter of an upper roller of the pair of third rollers and a diameter of a lower roller of the pair of third rollers, which contact a specific point of the plate, are different.

14. A method for manufacturing a channel plate for forming a channel for transferring a substance to a plate, comprising:
a punching step for forming a plurality of openings on the plate using a pair of first rollers provided to have a predetermined pattern in a transport process of the plate; and
a pressurizing step for forming a channel on the plate by pressurizing a region having the plurality of openings of the punched plate with a pair of second rollers and bending the plate in a predetermined angle and direction, wherein at least one roller of the second pair of rollers has a raised pattern on an outer circumferential surface.

15. The method for manufacturing a channel plate according to claim 14 , further comprising a rolling step for rolling the plate in the transport process of the plate after the pressurizing step is completed.

16. The method for manufacturing a channel plate according to claim 15 , further comprising a spreading step for at least partially expanding the bent region of said plate in the transport process of the plate after the pressurizing step is completed.
