Abstract

A deburring apparatus includes (among other components) a frame and an elongated flat element connected to the frame. Rollers are adapted to support and rotate a vacuum belt around the apparatus. A perforation device is positioned and adapted to make perforations in the vacuum belt as the vacuum belt is rotated by the rollers. Making the perforations in the vacuum belt causes debris to remain in at least one of the perforations. The elongated flat element is positioned to contact the debris in the perforations.

First claim

What is claimed is:

1. An apparatus comprising:
a frame; and
an elongated flat element connected to the frame,
wherein a perforation device, separate from the elongated flat element, is positioned and adapted to make perforations in a continuous belt material that is supported and rotated around the perforation device by rollers that are connected to the frame,
wherein a vacuum device is positioned and adapted to draw debris from the perforations by applying negative pressure from the vacuum device to the perforations,
wherein the elongated flat element is positioned to contact remaining ones of debris in the perforations,
wherein the vacuum device is positioned, relative to the elongated flat element and the continuous belt material, to apply the negative pressure from the vacuum device to pull the continuous belt material against the elongated flat element,
wherein the elongated flat element comprises a knife edge,
wherein the elongated flat element is rotatable between a first position and a second position,
wherein the knife edge is positioned for the vacuum device to not pull the continuous belt material against the knife edge and for the knife edge to not contact the debris in the perforations when rotated to the first position, and
wherein the knife edge is positioned for the vacuum device to pull the continuous belt material against the knife edge and for the knife edge to contact the debris in the perforations when rotated to the second position.

2. The apparatus according to claim 1 , wherein the elongated flat element is rotatably connected to the frame.

3. The apparatus according to claim 1 , wherein the elongated flat element comprises the knife edge, and wherein the knife edge contacts the debris in the perforations.

4. The apparatus according to claim 1 , wherein the elongated flat element comprises metal, plastic, or ceramic.

5. The apparatus according to claim 1 , wherein the perforation device comprises a punch device or a laser cutting device.

6. The apparatus according to claim 1 , wherein the continuous belt material comprises a plastic substrate.

7. An apparatus comprising:
a frame;
a perforation device, wherein the perforation device is positioned and adapted to make perforations in a continuous belt material that is supported and rotated around the perforation device by rollers that are connected to the frame,
a vacuum device positioned and adapted to draw debris from the perforations by applying negative pressure from the vacuum device to the perforations; and
an elongated flat element connected to the frame separately from the perforation device, wherein the elongated flat element is positioned to contact remaining ones of the debris in the perforations,
wherein the vacuum device is positioned, relative to the elongated flat element and the continuous belt material, to apply the negative pressure from the vacuum device to pull the continuous belt material against the elongated flat element,
wherein the elongated flat element comprises a knife edge,
wherein the elongated flat element is rotatable between a first position and a second position,
wherein the knife edge is positioned for the vacuum device to not pull the continuous belt material against the knife edge and for the knife edge to not contact the debris in the perforations when rotated to the first position, and
wherein the knife edge is positioned for the vacuum device to pull the continuous belt material against the knife edge and for the knife edge to contact the debris in the perforations when rotated to the second position.

8. The apparatus according to claim 7 , wherein the elongated flat element is rotatably connected to the frame.

9. The apparatus according to claim 8 , wherein the elongated flat element comprises the knife edge, and wherein the knife edge contacts the debris in the perforations.

10. The apparatus according to claim 7 , wherein the elongated flat element comprises metal, plastic, or ceramic.

11. The apparatus according to claim 7 , wherein the perforation device comprises a punch device or a laser cutting device.

12. The apparatus according to claim 7 , wherein the continuous belt material comprises a plastic substrate.

13. A method comprising:
making perforations in a continuous belt material with a perforation device;
wherein the continuous belt material is supported by and rotated around the perforation device using rollers attached to a frame;
drawing debris from the perforations into a vacuum device by applying negative pressure from the vacuum device to the perforations; and
contacting remaining ones of the debris in the perforations using an elongated flat element connected to a frame separately from the perforation device,
wherein the applying the negative pressure from the vacuum device pulls the continuous belt material against the elongated flat element,
wherein the elongated flat element comprises a knife edge,
wherein the elongated flat element is rotatable between a first position and a second position,
wherein the knife edge is positioned for the vacuum device to not pull the continuous belt material against the knife edge and for the knife edge to not contact the debris in the perforations when rotated to the first position, and
wherein the knife edge is positioned for the vacuum device to pull the continuous belt material against the knife edge and for the knife edge to contact the debris in the perforations when rotated to the second position.

14. The method according to claim 13 , further comprising rotating the elongated flat element.

15. The method according to claim 13 , wherein the elongated flat element comprises the knife edge, and wherein the contacting of the debris is performed using the knife edge.

16. The method according to claim 13 , wherein the elongated flat element comprises metal, plastic, or ceramic.

17. The method according to claim 13 , wherein the perforation device comprises a punch device or a laser cutting device, and wherein the making of the perforations comprises using the punch device or the laser cutting device.
