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 a shoe part in an automated manner during a shoe-manufacturing process, the method comprising:
receiving an image depicting a two-dimensional representation of an attachment shoe part which is to be attached to a base shoe part;
determining one or more pixel coordinates of the image;
converting, by a computer processor, the one or more pixel coordinates of the image to a geometric coordinate of a geometric coordinate system which maps a three-dimensional space within which the attachment shoe part is positioned and a pick-up tool operates;
determining another geometric coordinate of the geometric coordinate system by analyzing a different image depicting a two-dimensional representation of the base shoe part to which the attachment shoe part will be attached; and
transferring, by the pick-up tool, the attachment shoe part to the other geometric coordinate, thereby moving the attachment shoe part to a location in the three-dimensional space at which the attachment shoe part is to be attached to the base shoe part.
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 and wherein the one or more pixel coordinates of the image are associated with the perimeter.
3. The method of claim 1 , further comprising determining the identity of the image by substantially matching the image to a reference image.
4. The method of claim 1 , wherein transferring the attachment shoe part to the other geometric coordinate comprises utilizing a vacuum-powered part holder of the pick-up tool 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 utilizing automated identification of the shoe parts and a multi-functional manufacturing tool, the method comprising:
receiving an image depicting a two-dimensional representation of an attachment shoe part which is to be attached to a base shoe part;
determining a geometric coordinate of a geometric coordinate system by analyzing the image, wherein the geometric coordinate system maps a three-dimensional space within which the attachment shoe part is positioned and the multi-functional manufacturing tool operates;
determining another geometric coordinate of the geometric coordinate system by analyzing a different image depicting a two-dimensional representation of the base shoe part to which the attachment shoe part will be attached;
transferring, by the a multi-functional manufacturing tool, the attachment shoe part to the other geometric coordinate, thereby moving the attachment shoe part to a location in the three-dimensional space at which the attachment shoe part is to be attached to the base shoe part; and
attaching, by the multi-functional manufacturing tool, the attachment shoe part to the base shoe part.
7. The method of claim 6 , wherein determining the geometric coordinate of the geometric coordinate system by analyzing the image comprises determining pixel coordinates of the image and converting the pixel coordinates of the image to the geometric coordinate of the geometric coordinate system.
8. The method of claim 7 , wherein transferring the attachment shoe part to the other geometric coordinate comprises utilizing a vacuum-powered part holder of the multi-functional manufacturing tool to transfer the attachment shoe part.
9. The method of claim 6 , wherein attaching the attachment shoe part to the base shoe part comprises utilizing an ultrasonic welding horn of the multi-functional manufacturing tool to attach the attachment shoe part to the base shoe part.
10. A system that positions and attaches a shoe part in an automated manner during a shoe-manufacturing process, the system comprising:
an image recorder that records an image depicting a two-dimensional representation of an attachment shoe part, which is to be attached to a base shoe part; and
computer storage media having stored thereon computer-executable instructions that, when executed, cause a computing device to:
(1) determine pixel coordinates of the image,
(2) convert the pixel coordinates of the image to a geometric coordinate in a geometric coordinate system, which maps a three-dimensional space within which the attachment shoe part is positioned and a manufacturing tool operates,
(3) determine another geometric coordinate in the geometric coordinate system by analyzing a different image of the base shoe part, and
(4) instruct a manufacturing tool to transfer the attachment shoe part to the other geometric coordinate, thereby moving the attachment shoe part to a location in the three-dimensional space at which the attachment shoe part is to be attached to the base shoe part.
11. The system of claim 10 further comprising another image recorder, wherein the different image of the base shoe part is recorded by the other image recorder.
12. The system of claim 10 further comprising a light-emitting device that provides a backlight to the attachment shoe part when the image is recorded.
13. The system of claim 10 , wherein the manufacturing tool comprises at least a vacuum-powered part holder having a bottom surface adapted for contacting the attachment shoe part.
14. The system of claim 13 , wherein the vacuum-powered part holder is comprised of a vacuum plate having a plurality of apertures extending through an interior plate surface and the bottom surface.
15. The system of claim 13 , wherein the vacuum-powered part holder is comprised of a single aperture extending through the bottom surface.
16. The system of claim 13 wherein the manufacturing tool further comprises at least an ultrasonic-welding horn coupled to the vacuum-powered part holder.
17. The system of claim 16 , wherein the ultrasonic-welding horn comprises at least a distal end adapted for contacting the attachment part such that the distal end extends at least to a plane defined by the vacuum-powered part holder bottom surface.
18. The system of claim 17 , wherein only one of the vacuum-powered part holder or the ultrasonic-welding horn are useable for a respective intended purpose at one time.
19. The system of claim 17 , wherein both of the vacuum-powered part holder and the ultrasonic-welding horn are useable for their respective intended purpose at one time.
