1. WO2020118070 - AUTOMATED HEAT SHRINKING FOR A TELECOMMUNICATIONS PRODUCT

Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters

[ EN ]

What is claimed is:

1. A method for sealing a telecommunications product, the telecommunications product defining an interior space and having at least one cable extending from the interior space to an exterior through an opening having a tubular body, the method comprising: securing the telecommunications product to an apparatus, the apparatus including heat blasters each configured to emit hot air;

positioning a shrink wrap tubing of a predetermined length over an outside surface of the cable and an outside surface of the tubular body of the opening; and

initiating a heat sealing operation that includes:

moving the heat blasters along a first plane toward the shrink wrap tubing until the heat blasters surround the shrink wrap tubing;

delivering hot air from each heat blaster; and moving the heat blasters along a second plane along a

predetermined length of the shrink wrap tubing, the second plane orthogonal to the first plane.

2. The method of claim 1, wherein the heat sealing operation includes delivering the hot air in a 360 degree direction around the shrink wrap tubing.

3. The method of claim 2, further comprising delivering the hot air from each heat blaster according to a heat profile that varies the time the hot air is delivered along the second plane.

4. The method of claim 3, wherein the heat profile delivers the hot air at a constant temperature along the predetermined length of the shrink wrap tubing

5. The method of claims 3 or 4, wherein the heat profile includes delivering the hot air at about 100° C to about 140°C for a variable amount of time along the second plane.

6. The method of claims 3 or 4, wherein the heat profile includes delivering the hot air to a first section of the shrink wrap tubing before delivering the hot air to a second section of the shrink wrap tubing, the second section being farther away from the interior space of the telecommunications product than the first section.

7. The method of claims 3 or 4, wherein the heat profile includes delivering the hot air to distal ends of the shrink wrap tubing for a first predetermined period of time, and delivering the hot air to central sections of the shrink wrap tubing for a second predetermined period of time, the first predetermined period of time being larger than the second predetermined period of time.

8. The method of claim 1, further comprising using a clamp to secure the telecommunications product to the apparatus.

9. The method of claim 1, further comprising using a clamp to secure the at least one cable to a frame of the apparatus.

10. The method of any one of the preceding claims, further comprising:

moving the heat blasters away from the shrink wrap tubing along the first plane; initiating a cooling operation; and

removing the telecommunications product from the apparatus.

11. An apparatus for sealing a telecommunications product that has a non-activated shrink wrap tubing positioned over a cable and an opening, the apparatus comprising: a frame;

heat blasters attached to the frame and movable with respect to the frame in both a first plane and a second plane, the second plane being orthogonal to the first plane, each heat blaster having a heat generator at a first end and an air deflector at a second end; and a controller having at least one processing unit and a system memory storing instructions that, when executed by the at least one processor, cause the heat blasters to:

move along the first plane relative to the telecommunications product; move along the second plane relative to the telecommunications product; and

deliver hot air from the heat generator and through the air deflector to activate the shrink wrap tubing and seal the cable and the opening.

12. The apparatus of claim 11, wherein the air deflectors each have a slit opening.

13. The apparatus of claim 12, wherein the slit opening has a center portion and terminal ends, the width of the terminal ends being wider than the center portion.

14. The apparatus of claims 12 or 13, wherein the air deflectors each have a flat bottom portion and a sloped top portion that direct the flow of hot air through a slit opening.

15. The apparatus of claims 12, 13, or 14, wherein the air deflectors each have a semi circular shape and a slit opening that delivers hot air in a 180 degree direction.

16. The apparatus of claim 11, wherein the heat blasters are positioned at opposite sides of the frame, such that when moved together along the first plane, the heat blasters deliver hot air in a 360 degree direction around the opening of the telecommunications product.

17. The apparatus of claim 11, wherein the instructions further cause the heat blasters to:

perform a heat profile that varies the amount of time that the hot air is delivered to sections of the shrink wrap tubing along the second plane.

18. The apparatus of claim 17, wherein the heat profile includes delivering the hot air to a first section of the shrink wrap tubing before delivering the hot air to a second section of the shrink wrap tubing, the second section being farther away from an interior space of the telecommunications product than the first section.

19. The apparatus of claims 17 or 18, wherein the heat profile includes delivering the hot air at a constant temperature of about 100° C to about 140°C for a variable amount of time along a predetermined length of the shrink wrap tubing.

20. The apparatus of claim 11, further comprising an attachment device having a back plate and side panels configured to at least partially surround the telecommunications product, and wherein the attachment device includes a clamp that secures the

telecommunications product to the back plate, and a heat shield that covers a top portion of the telecommunications product.
