JPH0540211A - Fine line inserting device - Google Patents

Abstract

PURPOSE:To provide a fine line inserting device which can exactly position fine lines and a ferrule and can stably insert the fine lines. CONSTITUTION:The ferrule 1 is aligned in a V-groove 21 and positioned on a ferrule stage 22. The fine line 2 is pulled from a spool 24, the head is positioned by a fine line guide 30, and the fine line is clamped by a clamping chuck 25 and transferred in the inserting direction by an insertion stage 26. The fine line 2 is inserted to the fine diameter hole 27 of the ferrule 1 and cut off by driving an actuator 28. During this operation, the fine line 2 is always positioned by the fine line guide 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for inserting a thin wire, and more particularly to an apparatus for inserting an optical fiber into a ferrule in an optical fiber connector assembling process.

[0002]

2. Description of the Related Art As shown in FIG. 2, a conventional thin wire insertion device holds a ferrule aligning portion 11 for positioning and fixing a ferrule 1 and a continuous thin wire 2 for positioning to move the ferrule 1 in the direction of a small diameter hole of the ferrule 1. The moving thin wire feeding unit 12 and the thin wire feeding unit 13 that feeds the continuous thin wire 2 to the thin wire feeding unit 12.
And the thin wire 3 in which the ferrule 1 is inserted and the continuous thin wire 2
And a cutting and separating cutter unit 14.

Next, the operation of the conventional thin wire insertion device will be described.

The ferrule 1 is positioned and aligned by the V groove 21 provided in the ferrule aligning portion 11, and the ferrule stage 22 is driven to position the first ferrule 1 at the insertion position. Next, the continuous thin wire 2 in the thin wire supply unit 13
Is pulled out from the spool 24, and the gripping chuck 25 of the fine wire feeding section 12 grasps and positions a portion apart from the tip by an insertion length or more, and the insertion stage 26 is driven to move the continuous thin wire 2 through the gripping check 25 to the first position. The ferrule 1 is moved toward the small diameter hole 27 and inserted. Then, the actuator 28 of the cutter unit 14 is driven to cut the continuous thin wire 2 by the cutting blade 29, and the inserted thin wire 3 is separated.

[0005]

In this conventional thin wire inserting apparatus, since the gripping chuck grips a portion apart from the end of the continuous thin wire by the insertion length or more, positioning is performed simultaneously. The instability of the gripping accuracy of the gripping chuck that repeats gripping and opening for each insertion operation is magnified by the length from the gripping portion to the end of the thin wire,
The ferrule, the thin wire, and the positioning accuracy are lowered, and the insertion probability is lowered.

[0006]

According to the present invention, there is provided a ferrule aligning portion for positioning and fixing a ferrule having a small diameter hole for fitting with a fine wire, and grasping and positioning the wiring, and the small diameter hole of the ferrule. A fine wire insertion device that includes a fine wire feeding unit that moves in a direction, a fine wire feeding unit that supplies a continuous fine wire to the fine wire feeding unit, and a cutter unit that cuts and separates the fine wire inserted into the ferrule from the continuous fine wire. In, there is a thin wire guide portion which is arranged near the thin wire feeding portion and which guides and instructs the thin wire.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, 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 the present invention comprises a V groove 21 for positioning and aligning a plurality of ferrules 1, a ferrule stage 22 for sequentially positioning only one of the plurality of ferrules 1 to a thin wire insertion position, and a continuous thin wire. A grip check 25 for gripping a continuous thin wire 2 whose one end is pulled out from a spool 24 for supplying 2; an insertion stage 26 for moving the grip chuck 25 in the insertion direction; and a thin wire intermediate the V groove 21 and the grip check 25. The cutter portion 14 for cutting the blade is provided, and the thin wire guide 30 provided in the vicinity of the grip check 25 side of the cutter portion 14 and having a thin hole for fitting with a thin wire.

Next, the operation of this embodiment will be described.

First, the ferrule 1 is positioned and aligned by the V groove 21, and the ferrule stage 22 is driven to position the first ferrule 1 at the insertion position. Next, after pulling out the continuous thin wire 2 from the spool 24 and inserting it into the thin wire guide 30, a portion apart from the tip end by the insertion length or more is grasped by the grasp check 27, and the insertion stage 25 is driven to operate the grasp check 25. The continuous thin wire 2 is the first ferrule 1
Move to the direction of the small diameter hole 27 and insert. At this time, the continuous thin wire 2 is properly positioned by the gripping chuck 25 and the thin wire guide 30. Further, the actuator 28 of the cutter unit 14 is driven to cut the continuous thin wire 2 by the cutting blade 29, the inserted thin wire 3 is separated, and then the ferrule stage 22 is driven to position the second ferrule 1. The gripping chuck 25 grips the portion of the continuous thin wire 2 away from the cut end by the insertion length or more, and thereafter, the insertion operation is continuously performed in the same manner. During this time, the tip of the continuous thin wire 2 is always positioned by the thin wire guide 30.

[0012]

As described above, according to the present invention, since the fine wire guide is provided in the vicinity of the cutter portion, it is possible to always position the fine wire at a position closer to the ferrule than the gripping chuck, and the insertion operation can be performed. At this time, there is no influence of instability of the gripping accuracy of the gripping chuck which repeats gripping and opening. This has the effect of stabilizing the alignment accuracy between the ferrule and the thin wire and increasing the insertion probability.
