Automated identification and assembly of shoe parts
Manufacturing and assembly of a shoe or a portion of a shoe is enhanced by automated placement and assembly of shoe parts. For example, a part-recognition system analyzes an image of a shoe part to identify the part and determine a location of the part. Once the part is identified and located, the part can be manipulated by an automated manufacturing tool.
1. A method for positioning and assembling shoe parts in an automated manner during a shoe-manufacturing process, the method comprising:
receiving a first image depicting a two-dimensional representation of an attachment shoe part which is to be attached to a base shoe part;
determining a first geometric coordinate in a geometric coordinate system of the attachment shoe part by analyzing the first image;
receiving a second image depicting a two-dimensional representation of the base shoe part;
determining a second geometric coordinate in the geometric coordinate system of the base shoe part by analyzing the second image; and
transferring, by a pickup tool, the attachment shoe part from the first geometric coordinate to the second geometric coordinate.
2. The method of claim 1 , wherein the two-dimensional representation of the attachment shoe part is comprised of a two-dimensional shape having a perimeter, wherein one or more pixel coordinates of the first image are associated with the perimeter, and wherein the method further comprises converting, by a computer processor, the one or more pixel coordinates to the first geometric coordinate.
3. The method of claim 1 , further comprising determining the identity of the attachment shoe part by matching the first image to a reference image.
4. The method of claim 1 , wherein the pickup tool further comprises a vacuum-powered part holder, and wherein transferring the attachment shoe part to the second geometric coordinate comprises utilizing the vacuum-powered part holder to transfer the attachment shoe part.
5. The method of claim 1 , further comprising attaching the attachment shoe part to the base shoe part.
6. A method of positioning and joining a plurality of shoe parts using automated identification and a multi-functional manufacturing tool, the method comprising:
receiving a first image depicting a two-dimensional representation of an attachment shoe part which is to be attached to a base shoe part;
determining a first geometric coordinate of the attachment shoe part in a geometric coordinate system by analyzing the first image;
receiving a second image depicting a two-dimensional representation of the base shoe part;
determining a second geometric coordinate of the base shoe part in the geometric coordinate system by analyzing the second image; and
transferring, using the multi-functional manufacturing tool, the attachment shoe part from the first geometric coordinate to the second geometric coordinate.
7. The method of claim 6 , further comprising attaching the attachment shoe part to the base shoe part.
8. The method of claim 7 , wherein attaching the attachment shoe part to the base shoe part comprises using an ultrasonic welding horn attached to the multi-functional manufacturing tool to attach the attachment shoe part to the base shoe part.
9. The method of claim 6 , wherein determining the first geometric coordinate comprises determining pixel coordinates of the first image and converting the pixel coordinates to the first geometric coordinate.
10. The method of claim 6 , wherein transferring the attachment shoe part to the second geometric coordinate comprises utilizing a vacuum-powered part holder attached to the multi-functional manufacturing tool to transfer the attachment shoe part.
11. A system that positions and attaches shoe parts in an automated manner during a shoe-manufacturing process, the system comprising:
at least one image recorder configured to record:
a first image depicting a two-dimensional representation of an attachment shoe part; and
a second image depicting a two-dimensional representation of a base shoe part; and
one or more computer storage media having stored thereon computer-executable instructions that, when executed, cause a computing device to:
determine a first geometric coordinate of the attachment shoe part in a geometric coordinate system by analyzing the first image;
determine a second geometric coordinate of the base shoe part in the geometric coordinate system by analyzing the second image; and
instruct a manufacturing tool to transfer the attachment shoe part from the first geometric coordinate to the second geometric coordinate for attachment to the base shoe part.
12. The system of claim 11 , further comprising the manufacturing tool, the manufacturing tool adapted to transfer the attachment shoe part to the base shoe part for attachment.
13. The system of claim 11 , wherein the at least one image recorder comprises at least one first camera that records the first image and at least one second camera that records the second image.
14. The system of claim 11 , wherein the manufacturing tool comprises at least a vacuum-powered part holder having a bottom surface adapted for contacting the attachment shoe part.
15. The system of claim 14 , wherein the vacuum-powered part holder is comprised of a vacuum plate having a plurality of apertures extending through the vacuum plate.
16. The system of claim 14 , wherein the vacuum-powered part holder is comprised of a vacuum plate having a single aperture extending through the vacuum plate.
17. The system of claim 14 , wherein the manufacturing tool further comprises at least an ultrasonic-welding horn coupled to the vacuum-powered part holder.
18. The system of claim 17 , wherein the ultrasonic-welding horn comprises at least a distal end adapted for contacting the attachment shoe part such that the distal end extends at least to a plane defined by the bottom surface of the vacuum-powered part holder.
19. The system of claim 17 , wherein only one of the vacuum-powered part holder and the ultrasonic-welding horn is useable for a respective intended purpose at one time.
20. The system of claim 17 , wherein both the vacuum-powered part holder and the ultrasonic-welding horn are useable for a respective intended purpose at one time.
