Abstract

A conveyor, a developing system and a developing method are provided. The conveyor includes a conveying unit configured to convey a substrate and having a plurality of conveying portions. The plurality of conveying portions includes a first tilt conveying portion and a second tilt conveying portion. One of a conveying surface of the first tilt conveying portion and a conveying surface of the second tilt conveying portion is a rising surface configured to raise the substrate gradually, and the other one of the conveying surfaces is a falling surface configured to bring down the substrate gradually.

First claim

What is claimed is:

1. A conveyor, comprising a conveying unit configured to convey a substrate and having a plurality of conveying portions, the plurality of conveying portions comprising a first tilt conveying portion and a second tilt conveying portion, wherein
one of a conveying surface of the first tilt conveying portion and a conveying surface of the second tilt conveying portion is a rising surface configured to raise the substrate gradually, and the other one of the conveying surfaces is a falling surface configured to bring down the substrate gradually,
wherein each of the conveying portions comprises a plurality of roller groups, each roller group comprises a plurality of rollers spaced apart from each other along a length direction of the roller group, and axes of the roller groups of the conveying unit are all located in a same plane, said plane being a first plane, and
wherein the rollers in each roller group have a same diameter.

2. The conveyor according to claim 1 , wherein the plurality of conveying portions further comprises a third conveying portion between the first tilt conveying portion and the second tilt conveying portion, and the third conveying portion is configured to convey the substrate in a plane in parallel with the first plane.

3. The conveyor according to claim 2 , wherein the plurality of roller groups of the third conveying portion is a plurality of third roller groups, and diameters of the plurality of third roller groups are the same to each other in a conveying direction of the substrate.

4. The conveyor according to claim 1 , wherein the plurality of roller groups of the first tilt conveying portion are a plurality of first roller groups, and diameters of the plurality of first roller groups are gradually decreased one by one in a conveying direction of the substrate.

5. The conveyor according to claim 4 , wherein the plurality of roller groups of the second tilt conveying portion are a plurality of second roller groups, and diameters of the plurality of second roller groups are gradually increased one by one in the conveying direction of the substrate.

6. The conveyor according to claim 1 , wherein the plurality of roller groups of the first tilt conveying portion are a plurality of first roller groups, and diameters of the plurality of first roller groups are gradually increased one by one in a conveying direction of the substrate.

7. The conveyor according to claim 6 , wherein the plurality of roller groups of the second tilt conveying portion are a plurality of second roller groups, and diameters of the plurality of second roller groups are gradually decreased one by one in the conveying direction of the substrate.

8. The conveyor according to claim 1 , wherein a length of the first tilt conveying portion is substantially the same as a length of the second tilt conveying portion, in a conveying direction of the substrate.

9. The conveyor according to claim 1 , wherein the plurality of conveying portions further comprises a fourth buffer conveying portion disposed at a side of the first tilt conveying portion distal to the second tilt conveying portion and configured to convey the substrate on a surface in parallel with the first plane; and a fifth buffer conveying portion disposed at a side of the second tilt conveying portion distal to the first tilt conveying portion and configured to convey the substrate on a surface in parallel with the first plane.

10. The conveyor according to claim 1 , wherein an acute angle between the conveying surface of the first tilt conveying portion and the first plane is α, and an acute angle between the conveying surface of the second tilt conveying portion and the first plane is α.

11. The conveyor according to claim 10 , wherein the acute angle α ranges from approximately 1 degree to approximately 30 degrees.

12. The conveyor according to claim 11 , wherein the acute angle α ranges from approximately 4 degrees to approximately 6 degrees.

13. A developing system, comprising the conveyor of claim 1 and a spray unit disposed above the conveying unit, the spray unit being configured to spray developer on a substrate to be developed,
wherein the spray unit comprises a plurality of nozzles disposed at intervals in a conveying direction of the substrate, and
wherein the plurality of nozzles are arranged right above the plurality of conveying portions, respectively.

14. The developing system according to claim 13 , wherein the plurality of conveying portions further comprises a third conveying portion between the first tilt conveying portion and the second tilt conveying portion, and the third conveying portion is configured to convey the substrate in a plane in parallel with the first plane.

15. The developing system according to claim 13 , wherein the plurality of roller groups of the first tilt conveying portion are a plurality of first roller groups, the plurality of roller groups of the second tilt conveying portion are a plurality of second roller groups, and wherein
in a conveying direction of the substrate, diameters of the plurality of first roller group are gradually decreased one by one and diameters of the plurality of second roller groups are gradually increased one by one; or
in the conveying direction of the substrate, diameters of the plurality of first roller groups are gradually increased one by one and diameters of the plurality of second roller groups are gradually decreased one by one.

16. A developing method using the developing system of claim 13 , comprising a step of:
placing a substrate on the conveyor to convey the substrate; and
turning on respective nozzles arranged right above respective conveying portions to spray developer on the substrate when the substrate is conveyed through the respective conveying portions.
