Abstract

An O-ring and a conveyance apparatus are provided. The O-ring includes an O-ring body having an annular shape. The O-ring further includes a plurality of protrusions arranged at intervals on an outer annular surface of the O-ring body and configured to support a glass substrate and convey the glass substrate as the O-ring body rotates, so that a total area of contact between the glass substrate and the O-ring is reduced, thereby reducing a print area. In addition, after the protrusions and the glass substrate come into contact, contact marks are in a discontinuous state or, in other words, are in a spaced state, and prints are also discontinuous or spaced prints, thereby mitigating visual effects of the prints, and eliminating the prints at low costs.

First claim

What is claimed is:

1. An O-ring, comprising:
an O-ring body, having an annular shape; and
a plurality of protrusions, arranged at intervals on an outer annular surface of the O-ring body, and configured to support a glass substrate and convey the glass substrate as the O-ring body rotates, wherein
each protrusion is a cylindrical protrusion, and a lateral surface in a radial direction of the cylindrical protrusion is fixedly connected to the O-ring body;
a first central line in an axial direction of the cylindrical protrusion is parallel to a tangent surface in a corresponding position on the O-ring body and is set at an angle from a second central line in an axial direction of the O-ring body, and the angle ranges from 50 to 20°;
a cross section of the O-ring body has a circular shape or has a rectangular shape; and
the O-ring body and the cylindrical protrusions are integrally formed.

2. A conveyance apparatus, comprising:
a plurality of roller shafts, disposed in a conveyance direction, each roller shaft being sheathed with a plurality of O-rings, wherein
the O-ring comprises an O-ring body having an annular shape; and
the O-ring further comprises a plurality of protrusions arranged at intervals on an outer annular surface of the O-ring body and configured to support a glass substrate and convey the glass substrate as the O-ring body rotates.

3. The conveyance apparatus according to claim 2 , wherein a plurality of rollers is disposed on each roller shaft, an annular groove is provided on an outer circumferential surface of each roller, the O-rings correspond one-to-one to the rollers, and each O-ring is sleeved over the annular groove of the corresponding roller.

4. The O-ring according to claim 1 , wherein a first central line in an axial direction of the cylindrical protrusion is parallel to a second central line in an axial direction of the O-ring body.

5. The O-ring according to claim 1 , wherein a first central line in an axial direction of the cylindrical protrusion is parallel to a tangent surface in a corresponding position on the O-ring body and is set at an angle from a second central line in an axial direction of the O-ring body.

6. The O-ring according to claim 1 , wherein the angle ranges from 100 to 150.

7. The O-ring according to claim 1 , wherein the protrusion is a hemispheric protrusion.

8. The O-ring according to claim 7 , wherein the protrusions are disposed along the outer annular surface of the O-ring body, and the protrusions are arranged into at least one circle.

9. The O-ring according to claim 8 , wherein the protrusions are arranged into two or more circles, and the protrusions in the circles are disposed in parallel.

10. The O-ring according to claim 9 , wherein the protrusions are arranged into two or more circles, and the protrusions in the circles are disposed in a staggered manner.

11. The O-ring according to claim 1 , wherein a cross section of the O-ring body has a circular shape or has a rectangular shape.

12. The O-ring according to claim 1 , wherein the O-ring body and the protrusions are integrally formed.

13. The O-ring according to claim 12 , wherein the O-ring body and the protrusions are integrally formed in an injection molding manner.

14. The O-ring according to claim 1 , wherein a plurality of grooves that correspond one-to-one to the protrusions are arranged at intervals on the outer annular surface of the O-ring body, and the protrusions are inserted in the corresponding grooves.

15. The O-ring according to claim 1 , wherein the O-ring body is made of a rubber material.

16. The O-ring according to claim 1 , wherein each protrusion is made of a rubber material.
