Ceramic inspection system
View Patent ↗A system for inspecting a ceramic component. The ceramic component is positioned on a first rotary table. The first rotary table rotates the ceramic component. Light is directed toward the first rotary table and the rotating ceramic component. A detector is located on a second rotary table. The second rotary table is operably connected to the first rotary table and the rotating ceramic component. The second rotary table is used to move the detector at an angle to the first rotary table and the rotating ceramic component.
1. An apparatus for inspecting a ceramic component having a concave inner surface and a convex outer surface, comprising:
a light table,
a rotary table operably connected to said light table,
a light source operably connected to said rotary table, said light source positioned to direct light to the concave inner surface of the ceramic component,
a detector, said detector positioned so that said detector receives light from the convex outer surface of the ceramic component to detect light that passes through the ceramic component from the concave inner surface to the convex outer surface, and
a robot arm operably connected to said rotary table that moves said detector in an arc along the convex outer surface of the ceramic component.
2. The apparatus for inspecting a ceramic component of claim 1 wherein said light source is a high intensity light source.
3. The apparatus for inspecting a ceramic component of claim 1 wherein said light source is a high intensity broad band light source.
4. The apparatus for inspecting a ceramic component of claim 1 wherein said detector includes a camera head.
5. The apparatus for inspecting a ceramic component of claim 1 wherein said rotary table and said robot arm are positioned at an angle to each other.
6. The apparatus for inspecting a ceramic component of claim 1 wherein said rotary table and said robot arm are positioned perpendicular to each other.
7. An apparatus for inspecting a ceramic component having a concave inner surface and a convex outer surface, comprising:
a support means,
rotary table means operably connected to said support means for rotating the ceramic component,
light source means operably connected to said rotary table for directing light toward said rotary table and the rotating ceramic component, said light source means positioned to direct light to the concave inner surface of the ceramic component,
detector means for producing a scan of the rotating ceramic component, and
robot means operably connected to said rotary table for moving said detector in an arc along the convex outer surface of the ceramic component.
8. The apparatus for inspecting a ceramic component of claim 7 wherein said detector means is a camera detector that produces a scan of the rotating ceramic component.
9. The apparatus for inspecting a ceramic component of claim 8 including means for using said scan to produce a visual image of the ceramic component.
10. A method for inspecting a ceramic component having a concave inner surface and a convex outer surface, comprising the steps of:
positioning the ceramic component on a rotary table and rotating the ceramic component,
directing light toward said first rotary table and the rotating ceramic component and onto the concave inner surface of the ceramic component,
positioning a detector on a robot that is operably connected to said rotary table and the rotating ceramic component, said detector positioned so that said detector receives light from the convex outer surface of the ceramic component to detect light that passes through the ceramic component from the concave inner surface to the convex outer surface, and
using said robot to move said detector at an angle to said rotary table and the rotating ceramic component, said robot moving said detector in an arc along the convex outer surface of the ceramic component to produce a scan of the rotating ceramic component.
11. The method for inspecting a ceramic component of claim 10 wherein said step of directing light toward said rotary table and the rotating ceramic component comprises directing high intensity light toward said first rotary table and the rotating ceramic component.
12. The method for inspecting a ceramic component of claim 11 wherein said step of directing light toward said rotary table and the rotating ceramic component comprises directing high intensity broad band light toward said first rotary table and the rotating ceramic component.
13. The method for inspecting a ceramic component of claim 11 wherein said step of using said robot to move said detector at an angle to said rotary table and the rotating ceramic component comprises moving said detector in an arc generally perpendicular to said rotary table.
14. The method for inspecting a ceramic component of claim 11 wherein said step of using said robot to move said detector at an angle to said rotary table comprises using a camera detector to scan the rotating ceramic component.
15. The method for inspecting a ceramic component of claim 14 wherein said camera detector produces a scan of the rotating ceramic component.
16. The method for inspecting a ceramic component of claim 15 wherein said scan of the rotating ceramic component is used to produce a visual image of the ceramic component.
