Automated scanning system and method
View Patent ↗A system and method for mass, automated scanning of objects, including dental study casts, housing parts, and other objects. The system and method are able to function with little or no human operator intervention, thereby facilitating high volume scanning and reducing scanning costs. The system includes a scanner having a scanning table, a conveyor mechanism adjacent the scanner for delivering objects to be scanned to the scanner, and a pick and place mechanism for taking an object from the conveyor mechanism and mounting it onto the scanning table of the scanner.
1. A scanning system for scanning a plurality of dental study casts, comprising:
a laser scanner, said scanner arranged and configured to collect data relating to the shape of the dental study casts;
a plurality of cassettes upon which the dental study casts to be scanned are mounted, wherein the dental study casts include both maxilla and mandible study casts mounted on each of said cassettes;
a conveyor mechanism adjacent said scanner for delivering said cassettes to said scanner, whereby the dental study casts are delivered to said scanner; and
a pick and place mechanism for taking said cassettes from said conveyor mechanism and mounting it on said scanner.
2. The system of claim 1 , wherein said laser scanner is mounted for movement along at least two mutually perpendicular axes.
3. The system of claim 2 , wherein said scanner includes a scanning table that is mounted for movement along an axis perpendicular to said two mutually perpendicular axes, and wherein said scanning table is rotatable.
4. The system of claim 1 , wherein said conveyor mechanism includes an infeed conveyor and an outfeed conveyor.
5. The system of claim 1 , further including an operator input station adjacent said scanner.
6. The system of claim 1 , further including an identification tag fixed to each of said cassettes.
7. The system of claim 6 , wherein each of said identification tags includes information relating to the dental study casts.
8. A method of scanning of objects by a scanner having a scanning table, comprising:
a) conveying objects to be scanned to the scanner using a conveyor mechanism, wherein the objects are dental study casts, and further including mounting maxilla and mandible study casts patient on one cassette;
b) picking an object from the conveyor mechanism and mounting the object on the scanning table of the scanner;
c) scanning the object without intermediate steps and collecting data on the physical shape of the object; and
d) removing the scanned object from the scanning table and delivering the scanned object to a discharge location.
9. The method of claim 8 , further including:
picking an additional object to be scanned from the conveyor mechanism, and mounting the additional object on the scanning table, and repeating steps c) and d).
10. the method of claim 8 , wherein mounting the object on the scanning table comprises mounting the cassette on the scanning table whereby the maxilla and mandible study casts are scanned together.
11. The method of claim 8 , further including mounting the maxilla and mandible study casts on the cassette in known positions relative to one another.
12. The method claim 8 , further including reading an identification tag fixed to said cassette.
13. A system for mass, automated scanning of dental study casts, comprising:
a scanner having a scanning table;
a plurality of cassettes, each said cassette having a maxilla and mandible study cast for a single patient mounted thereon in known positions relative to each another;
a conveyor adjacent the scanner for delivering the cassettes to the scanner; and
a pick and place mechanism engageable with said cassettes for picking one of said cassettes from said conveyor and mounting the picked cassette on said scanning table.
14. The system of claim 13 , wherein said scanner is a laser scanner.
