Abstract

A wire inspection system is provided. The wire inspection system includes a mirror assembly including an odd number of sides arranged to form a pyramid structure configured to surround a wire segment, wherein a plurality of the sides include a mirror, a light source configured to illuminate the wire segment, and at least one camera configured to acquire a plurality of images of the wire segment that are reflected by the plurality of mirrors, wherein each image of the plurality of images shows a different side of the wire segment.

First claim

What is claimed:

1. A wire inspection system comprising:
a mirror assembly comprising an odd number of sides greater than two arranged to form a pyramid structure configured to surround a wire segment, wherein a plurality of said sides comprise a mirror;
wherein each mirror is sized to occupy less than half of a surface of an associated side;
a light source configured to illuminate the wire segment; and
at least one camera configured to acquire a plurality of images of the wire segment that are reflected by said plurality of mirrors, wherein each image of the plurality of images shows a different side of the wire segment.

2. A wire inspection system in accordance with claim 1 , further comprising a computer communicatively coupled to said at least one camera and configured to assess a crimp quality of the wire segment based on the plurality of images.

3. A wire inspection system in accordance with claim 1 , further comprising a computer communicatively coupled to said at least one camera and configured to assess a strip quality of the wire segment based on the plurality of images.

4. A wire inspection system in accordance with claim 1 , wherein at least one of said light source and said at least one camera comprises a pair of polarizing filters.

5. A wire inspection system in accordance with claim 1 , wherein each side of said mirror assembly comprises a mirror.

6. A wire inspection system in accordance with claim 1 , further comprising a positive air pressure system configured to cool said at least one camera and configured to substantially prevent dust and dirt from entering an enclosure housing said plurality of mirrors.

7. A wire inspection system in accordance with claim 1 , wherein said at least one camera comprises a single high-resolution camera.

8. A wire inspection system in accordance with claim 1 , wherein said at least one camera comprises a plurality of digital microscopes.

9. An automated wire segment processing system comprising:
at least one of a strip station configured to strip a wire segment and a crimp station configured to crimp the wire segment;
a controller configured to control operation of said strip station and said crimp station; and
a wire inspection system configured to assess at least one of a strip quality of a stripping operation performed on the wire segment by said strip station and a crimp quality of a crimping operation performed on the wire segment by said crimp station, said wire inspection system comprising:
a mirror assembly comprising an odd number of sides greater than two arranged to form a pyramid structure configured to surround the wire segment, wherein a plurality of said sides comprise a mirror;
wherein each mirror is sized to occupy less than half of a surface of an associated side;
a light source configured to illuminate the wire segment; and
at least one camera configured to acquire a plurality of images of the wire segment that are reflected by said plurality of mirrors, wherein each image of the plurality of images shows a different side of the wire segment.

10. An automated wire segment processing system in accordance with claim 9 , wherein said controller is configured to transmit, to said wire inspection system, data indicative of characteristics of the wire segment.

11. An automated wire segment processing system in accordance with claim 9 , wherein said mirror assembly comprises five sides.

12. An automated wire segment processing system in accordance with claim 9 , wherein each side of said mirror assembly comprises a mirror.

13. An automated wire segment processing system in accordance with claim 9 , further comprising a positive air pressure system configured to cool said at least one camera and configured to substantially prevent dust and dirt from entering an enclosure housing at least one of said at least one camera and said plurality of mirrors.

14. A method for inspecting a wire segment, the method comprising:
inserting the wire segment into a mirror assembly, the mirror assembly including an odd number of sides greater than two arranged to form a pyramid structure that surrounds the wire segment, wherein a plurality of the sides include a mirror;
wherein each mirror is sized to occupy less than half of a surface of an associated side;
illuminating the wire segment using a light source; and
acquiring a plurality of images of the wire segment that are reflected by the plurality of mirrors, wherein each image of the plurality of images shows a different side of the wire segment.

15. A method for inspecting a wire segment in accordance with claim 14 , wherein inserting the wire segment into a mirror assembly comprises inserting the wire assembly into a mirror assembly having five sides.

16. A method for inspecting a wire segment in accordance with claim 14 , wherein acquiring a plurality of images comprises acquiring a plurality of images using a single high-resolution camera.

17. A method for inspecting a wire segment in accordance with claim 14 , wherein acquiring a plurality of images comprises acquiring a plurality of images using a plurality of digital microscopes.

18. A wire inspection system in accordance with claim 1 , wherein each mirror is positioned to avoid viewing any other mirror of the mirror assembly.
