Description

Apparatus for coupling spool and pad in optical fiber draving system

The present invention relates to an automatic fusion apparatus, and more particularly, to a spool pad automatic fusion apparatus capable of automatically fusion of a cushion pad on a spool radial circumferential surface.

The core part of the spool used to wind the optical fiber is composed of a spool 11 and a cushion pad 12 as shown in Figs. 1A and 1B.

Conventionally, this spool and pad assembly has been used a method of bonding the pad after manually attaching the double-sided tape to the spool, this method has a problem of low productivity.

In addition, it is possible to use an expensive spool when the pad is poorly bonded to the assembly, but since the pad bonding is performed using double-sided tape, it is almost impossible to remove the pad and thus has no after-sales service.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coupling device of a spool and a pad for winding an optical fiber which can fuse the spool and the pad quickly and with high quality.

1A is a schematic diagram of a spool used for winding an optical fiber.

1B is a schematic diagram of a cushion pad fused with the spool of FIG. 1A.

Figure 1c shows the cushion pad is coupled to the spool.

Figure 2 is a block diagram of a coupling device of the optical fiber winding spool and pad according to the present invention.

Coupling device of the optical fiber winding spool and pad according to the present invention for solving the above technical problem, in the optical fiber manufacturing apparatus, a pad for protecting the breakage of the optical fiber by tension and to prevent non-linearity on the outer peripheral surface of the spool winding the optical fiber An apparatus for wrapping and bonding close to each other, comprising: pad guide means for wrapping a pad on the spool outer circumferential surface and bringing the pad into close contact with the spool outer circumferential surface; Fusion means for fusion bonding both end surfaces of the pad adhered to the outer circumferential surface of the spool by the pad guide means; And planarization means for planarizing both end surfaces of the pad thermally fused by the fusion means.

Hereinafter, a pad fusion apparatus of a spool for optical fiber winding according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 schematically shows a coupling device of the optical fiber winding spool and pad according to the present invention, the first pad guide means 21, the second pad guide means 22, the third pad guide means 23, The first conveying means 24, the second conveying means 25, the first supporting means 26, the second supporting means 27, the heat-heating means 28 and the flattening means 29.

In order to attach the pad 12 to the spool 11 which winds the optical fiber, the first pad guide means 21 guides the pad 12 to the spool 11 in close contact with the left side. The second pad guide means 22 guides the pad 12 on the right side so as to be in close contact with the spool 11. The third pad guide means 23 guides the pad 12 in close contact with the spool 11 at the bottom of the spool 11.

The front structures of the first pad guide means 21, the second pad guide means 22, and the third pad guide means 23 are rounded to smoothly surround the pad 12. Here, the first pad guide means 21 and the second pad guide means 22 are equally spaced horizontally with respect to the center point of the outer circumferential surface of the spool, and a symmetrical structure is preferable.

The first conveying means 24 and the second conveying means 25 may include heat heating means 28 for heat-heating the welded portion of the cushion pad 12 in close contact with the spool 11. It is conveyed while fusion bonding both end surfaces of the pad 12 from one end to the other end.

The first transfer means 24 comprises a first support means 26 and the second transfer means 25 comprise a second support means 27. The first support means 26 and the second support means 27 support the heat-heating means 28 for heating the heat at the welded portion of the pad 12 in close contact with the spool 11.

The thermal heating means 28 installed on the first pad guide means 21 and the second pad guide means 22 is a system capable of controlling an appropriate temperature and an appropriate wind pressure. The second support means 27 determines the positions of both end faces of the pad 12 to chuck and fusion the end faces of the pads.

The planarization means 29 can eliminate the protrusion and interference of the optical fiber during the winding of the optical fiber by flattening the projecting portion of the interface of the pad end surface fusion portion.

ADVANTAGE OF THE INVENTION According to this invention, it becomes possible to perform a high precision and high quality pad fusion operation | work of a spool and a pad quickly and continuously.
