Abstract

A supporting and transferring mechanism and a supporting and transferring device are provided. The supporting and transferring mechanism includes a gas supply portion, a supporting ball and an accommodating portion. An accommodating space is formed in the accommodating portion and the supporting ball is provided in the accommodating space. The gas supply portion is communicated with the accommodating portion to supply a gas of preset pressure into the accommodating space, so as to lift the supporting ball in the accommodating space such that a part of a surface of the supporting ball protrudes out of the accommodating portion. The part of the surface of the supporting ball protruding out of the accommodating portion supports and transfers the plate-like article.

First claim

What is claimed is:

1. A supporting and transferring mechanism for a plate-like article, comprising:
a gas supply portion;
an accommodating portion in which an accommodating space is formed;
a supporting ball in the accommodating space; and
a sealing sleeve,
wherein the gas supply portion is communicated with the accommodating portion and configured to supply a gas of preset pressure into the accommodating space, so as to lift the supporting ball in the accommodating space such that a part of a surface of the supporting ball protrudes out of the accommodating portion, and
wherein the part of the surface of the supporting ball protruding out of the accommodating portion supports the plate-like article so as to transfer the plate-like article,
wherein the gas supply portion comprises a gas supply passage configured to supply the gas of preset pressure into the accommodating space, and
wherein the accommodating space comprises a first opening which is communicated with an outlet of the gas supply passage and a second opening opposite to the first opening, and the gas supplied by the gas supply passage enters the accommodating space through the first opening, and the part of the surface of the supporting ball protrudes out of the accommodating portion through the second opening, and
wherein the sealing sleeve comprises a third opening that is the same as the second opening in size and shape and is configured to sleeve the accommodating portion and the gas supply portion therein and to align the third opening with the second opening, so as to prevent the gas from leaking out of the accommodating space.

2. The supporting and transferring mechanism according to claim 1 , wherein the accommodating portion comprises a first member and a second member that are opposite to each other, and the first member and the second member are assembled together to form the accommodating space.

3. The supporting and transferring mechanism according to claim 2 , wherein portions of both the first member and the second member that are located at the second opening are fitted with the surface of the supporting ball lifted by the gas.

4. The supporting and transferring mechanism according to claim 1 , wherein the supporting ball is made of glass or plastic.

5. The supporting and transferring mechanism according to claim 2 , wherein the first member and the second member are connected to the gas supply portion through a detachable connector.

6. A supporting and transferring device for driving a plate-like article, comprising:
at least one driving wheel configured to drive the plate-like article to move; and
at least one supporting and transferring mechanism according to claim 1 , configured to cooperate with the driving wheel so as to support and transfer the plate-like article.

7. The supporting and transferring device according to claim 6 , wherein the accommodating portion comprises a first member and a second member that are opposite to each other, and the first member and the second member are assembled together to form the accommodating space.

8. The supporting and transferring device according to claim 7 , wherein
portions of both the first member and the second member that are located at the second opening are fitted with the surface of the supporting ball lifted by the gas.

9. A supporting and transferring mechanism for a plate-like article, comprising:
a gas supply portion;
an accommodating portion in which an accommodating space is formed; and
a supporting ball in the accommodating space,
wherein the gas supply portion is communicated with the accommodating portion and configured to supply a gas of preset pressure into the accommodating space, so as to lift the supporting ball in the accommodating space such that a part of a surface of the supporting ball protrudes out of the accommodating portion, and
wherein the part of the surface of the supporting ball protruding out of the accommodating portion supports the plate-like article so as to transfer the plate-like article,
wherein the gas supply portion comprises a gas supply passage configured to supply the gas of preset pressure into the accommodating space, and
wherein the accommodating space comprises a first opening which is communicated with an outlet of the gas supply passage, and the gas supplied by the gas supply passage enters the accommodating space through the first opening, and
wherein the supporting and transferring mechanism, further comprises a magnetic member at the outlet of the gas supply passage;
wherein the supporting ball comprises a magnet ball which has the same polarity as the magnetic member so as to generate a repulsive force between the magnet ball and the magnetic member.

10. The supporting and transferring mechanism according to claim 9 , wherein the magnetic member is matched with the outlet of the gas supply passage in size and shape, and the magnetic member is provided with a plurality of through holes therein in a direction of gas entering through the first opening, the plurality of through holes being uniformly distributed in the magnetic member.

11. The supporting and transferring mechanism according to claim 9 , wherein the supporting ball further comprises a ball shell encapsulating the magnet ball, hardness of the ball shell being lower than hardness of the magnet ball; and
wherein the magnet ball is configured such that magnetic lines from the magnet ball pass through the ball shell.

12. The supporting and transferring mechanism according to claim 11 , wherein the ball shell is made of plastic or glass.

13. A supporting and transferring device for driving a plate-like article, comprising:
at least one driving wheel configured to drive the plate-like article to move; and
at least one supporting and transferring mechanism according to claim 9 , configured to cooperate with the driving wheel so as to support and transfer the plate-like article.

14. The supporting and transferring device according to claim 13 , wherein the magnetic member is matched with the outlet of the gas supply passage in size and shape, and the magnetic member is provided with a plurality of through holes therein in a direction of gas entering through the first opening, the plurality of through holes being uniformly distributed in the magnetic member.

15. The supporting and transferring device according to claim 13 , wherein the supporting ball further comprises a ball shell encapsulating the magnet ball, hardness of the ball shell being lower than hardness of the magnet ball; and
wherein the magnet ball is configured such that magnetic lines from the magnet ball pass through the ball shell.
