Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fine wire insertion device used for inserting an optical fiber into a ferrule when assembling an optical fiber connector.

[0002]

[Prior Art]

 FIG. 2 is a side view showing an example of a conventional fine wire insertion device.

A conventional thin wire insertion device used for inserting an optical fiber into a ferrule at the time of assembling an optical fiber connector has a structure as shown in FIG.

That is, a ferrule aligning portion 11 that positions and fixes the ferrule 1 having a small diameter hole that penetrates the thin wire 2, and a thin wire feeding portion that grips the thin wire 2 and transfers it to the small diameter hole of the ferrule 1. 12 and the thin wire feeding portion 13 for supplying the continuous thin wire 2 to the thin wire feeding portion 12, and the portion of the thin wire inserted into the small diameter hole of the ferrule 1 is cut from the portion gripped by the thin wire feeding portion 12. And a cutter unit 14 that separates them.

In the thin wire insertion device configured as described above, the ferrule 1 is positioned in the V groove 21 of the ferrule aligning section 11 based on its outer shape and aligned, and then the ferrule stage 22 of the ferrule aligning section 11 is driven. Move it to the specified position for inserting the thin wire 2 and fix it. Next, the continuous thin wire 2 is pulled out from the spool 24 in the thin wire supply unit 13, and a portion apart from the tip end by a predetermined length or more is held by the grip chuck 25 of the thin wire feeding unit 12. Then, the insertion stage 26 of the thin wire feeding section 12 is driven to transfer the tip portion of the thin wire 2 gripped by the gripping chuck 25 toward the ferrule 1 and insert it into the small diameter hole 27. When the insertion of the thin wire 2 into the ferrule 1 is completed, the actuator 28 of the cutter unit 14 is driven, the thin wire 2 is cut by the cutting blade 29, and the tip portion thereof is separated as the separated thin wire 3.

[0006]

[Problems to be solved by the device]

 In the conventional thin wire insertion device as described above, the portion of the continuous thin wire that is separated from the tip by a predetermined length or more is gripped by the gripping chuck of the thin wire feeding unit, and therefore, the thin wire by the gripping chuck is inserted each time the insertion operation is performed. The gripping and releasing of the thin wire is repeated.However, since the part to be gripped by the gripping chuck of the thin wire feeding part is the part that is more than a predetermined length away from the tip of the continuous thin wire, The gripping error is magnified at the tip of the thin wire, and there is a drawback that the position of the tip of the thin wire with respect to the ferrule increases and the probability of insertion decreases.

[0007]

[Means for Solving the Problems]

 The thin wire insertion device of the present invention comprises a ferrule aligning part for positioning and fixing a ferrule having a thin hole for penetrating the thin wire, and a thin wire feeding device for gripping the thin wire and transferring it to the thin hole of the ferrule. Section, a fine wire supplying section for supplying a continuous fine wire to the fine wire feeding section, and a portion of the fine wire inserted into the small diameter hole of the ferrule, cut from a portion gripped by the fine wire feeding section. In a thin wire insertion device comprising a cutter part for separating the thin wire, a thin wire guide part having a guide hole that penetrates the thin wire and fits into the small diameter hole of the ferrule is provided between the cutter part and the ferrule aligning part. It is provided.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a side view showing an embodiment of the present invention.

The thin wire insertion device of FIG. 1 holds the thin wire 2 and the ferrule aligning portion 11 for positioning and fixing the ferrule 1 having a small diameter hole for penetrating the thin wire 2 as in the conventional example of FIG. Of the fine wire inserted into the small hole of the ferrule 1, and the fine wire feeding section 12 for feeding the continuous fine wire 2 to the fine wire feeding section 12. The ferrule includes a cutter portion 14 that cuts and separates the portion from the portion gripped by the thin wire feeding portion 12, and further, the thin wire 2 is penetrated between the cutter portion 14 and the ferrule aligning portion 11. A thin wire guide portion 30 having a guide hole for guiding the small diameter hole 27 is provided. A taper is provided at the entrance of the guide hole so that the thin wire 2 can easily enter, and the exit is opposed to the small-diameter hole of the ferrule 1 positioned in the ferrule aligning portion 11.

The thin wire insertion device configured as described above drives the ferrule stage 22 of the ferrule aligning unit 11 after positioning and aligning the ferrule 1 in the V groove 21 of the ferrule aligning unit 11 based on the outer shape thereof. Move it to the specified position for inserting the thin wire 2 and fix it. Next, the continuous thin wire 2 is pulled out from the spool 24 in the thin wire supply unit 13, and a portion apart from the tip end by a predetermined length or more is held by the grip chuck 25 of the thin wire feeding unit 12. Then, the insertion stage 26 of the thin wire feeding section 12 is driven to transfer the tip portion of the thin wire 2 which is gripped by the gripping chuck 25 toward the ferrule 1. At this time, the tip portion of the thin wire 2 passes through the guide hole of the thin wire guide portion 30 and is sent to the ferrule 1, where it is accurately positioned and inserted into the thin hole 27 of the ferrule 1. When the insertion of the thin wire 2 into the ferrule 1 is completed, the actuator 28 of the cutter portion 14 is driven, the thin wire 2 is cut by the cutting blade 29, and the tip portion thereof is separated as the separated thin wire 3. When the insertion of the thin wire 2 into one ferrule is completed in this way, the ferrule stage 22 is driven to position the second ferrule, and the same operation is repeated.

[0012]

[Effect of the device]

 As described above, the thin wire insertion device of the present invention is provided with the thin wire guide portion having the guide hole that penetrates the thin wire and guides it into the small diameter hole of the ferrule between the cutter portion and the ferrule alignment portion. Since the position of the tip of the thin wire can be held accurately with respect to the small diameter hole of the ferrule, there is an effect that the probability of insertion can be improved, and therefore quality and productivity can be improved. The effect is that you can do it.
