Abstract

PURPOSE:To easily execute the suction work of an adhesive by inserting an optical fiber through a ferrule, and thereafter setting a coated optical fiber inserting tool to a suction base on a stage as it is, and setting automatically the tip of the ferrule to a suction port of a sucking unit. CONSTITUTION:On a stage 1a on the upper face of casing of a main body, a coated optical fiber inserting jig 2 and a suction port setting base 3 are provided. When the tip of an optical fiber 4 is fixed by pushing down a soft clamper 7a in the prescribed direction, and thereafter, moved along a slide surface 2a, a coated optical fiber of the tip of the optical fiber 4 can be inserted into a fine hole of a ferrule 5. Subsequently, in this state, the optical fiber 4 is fixed to the coated optical fiber inserting jig 2 and allowed to be slid to the left, and set to the inserting port set base 3. Consequently, by this slide operation, the tip of the ferrule 5 is set automatically to the suction port of the suction port set base 3, the adhesive 9 is sucked together with air and filled in the fine hole in the ferrule 5. In such a manner, the workability is improved.

Description

[Detailed Description of the Invention] [Industrial Application Field] This invention provides an adhesive suction system that can insert an optical fiber into a ferrule and adhere the optical fiber to the ferrule when manufacturing an optical connector. It concerns R.

E. Prior Art] Optical connectors have been developed to allow optical fibers to be freely connected to each other.

For example, this optical connector connects the tip end core wire of an optical fiber to 7
After the optical fiber is inserted into the microscopic hole of the ferrule, an adhesive is injected to fix the optical fiber core wire inserted into the microscopic hole to the ferrule.

Therefore, the following method has been used to inject this adhesive into the narrow micropores of the ferrule.

That is, first, an optical fiber is set in this ferrule in a predetermined state, the tip of the ferrule is fixed to the suction port of an inhaler connected to a predetermined suction means, and the air in the micropores on the ferrule side is sucked by the suction means. The adhesive is removed by suction and the negative pressure generated at this time is used to effectively inject the adhesive into the narrow fine hole through which the optical fiber core wire is inserted.

[Problem to be solved]

However, when inhaling adhesive using negative pressure using such an inhaler, a special jig with an insertion port is required to ensure that the tip of the ferrule is inserted into the tip of the inhaler's inlet. This is done by preparing one and attaching it to the inlet. Therefore, when using this jig, the tip of the 7-ferrule is inserted into the insertion opening of the jig, and the adhesive is sucked while holding the ferrule with one hand.

Therefore, such a suction operation inevitably has poor workability, which poses a problem.

Moreover, the work of inserting the optical fiber core into the ferrule, which is performed prior to such an adhesive suction operation, is particularly difficult due to the fact that the optical fiber core wire must be inserted visually into an extremely narrow hole. This is also a problem.

Therefore, in view of the above-mentioned conventional problems, the present invention provides an adhesive inhaler that can extremely easily perform the work of inserting an optical fiber core wire into a ferrule and the work of sucking adhesive into a ferrule after the optical fiber has been inserted. The purpose is to provide the following.

[Means to solve the problem]

That is, the adhesive inhaler of the present invention has a clamp part that holds the end of the optical fiber and moves on the sliding surface, and a fixing part that fixes the ferrule in a predetermined position, which is provided in front of the clamp part in the direction of movement. , a core wire insertion jig for inserting the core wire of the optical fiber into the fine hole of the ferrule, an inlet for moving the core wire insertion jig forward and inserting the tip of the ferrule fixed thereto, and a main body side A suction port set table is provided on the stage at the top of the main body, and has a communication path through which the suction means is communicated, and a suction port set table for sucking the adhesive for bonding the optical fiber into the fine hole of the ferrule inserted into the suction hole. .

[Effect]

The adhesive inhaler of this invention holds one end of the optical fiber in the clamp part of the core wire insertion jig provided on the stage surface of the adhesive inhaler, and fixes the ferrule to the fixing part,
By simply sliding the clamp part toward the fixing part to a predetermined position, the core wire of the optical fiber can be inserted into the fine hole of the ferrule extremely easily.

In addition, in this pharyngeal adhesive inhaler, after inserting the optical fiber into the ferrule, the core wire insertion jig is advanced toward the suction port set table on the stage where the adhesive is inhaled. When placed on the inhaler stand, the tip of the ferrule is automatically placed in the inhaler's inlet.

Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an adhesive inhaler according to the present invention, and this adhesive inhaler has a core wire insertion jig 2 and an inlet set stand 3 on a stage la on the upper surface of the casing of the main body 1.

The core wire insertion jig 2, as shown in FIGS. 2 and 3,
The core wire 4a of the optical fiber 4 in the form of a tape wire is connected to the ferrule 5.
The optical fiber 4 is inserted into the fine hole (not shown), and the tip of the 7 errule 5 after the optical fiber 4 has been inserted is set in the suction port of the suction port set table 3. It is attached in a slidable state and includes a clamp part 7 and a fixing part 8.

The clamp section 7 includes a soft clamper 7a that moves leftward along the slide shaft 2b on the slide surface 2a while holding one end of the optical fiber 4, as shown in FIG. The soft clamper 7a moves forward to a predetermined position, and the optical fiber 4
After the tip of the core wire 4a is inserted into the fine hole of the ferrule 5, it is held by a node clamper 7b which fixes the optical fiber 4 in this restrained state. The soft clamper 7a is attached to the core wire insertion jig 2 with a hinge or the like so that it can be rotated freely so that it can be placed over the optical fiber 4 from above. In order to securely hold the optical fiber 4 as it is, magnetic force such as a magnet is used. In addition, the hard clamper 7b is also rotatably mounted on a hinge or the like so that it can be placed over the optical fiber 4 from above on the sliding surface 2a, and similarly, the optical fiber is securely fixed and held by the magnetic force of the magnet. It is now possible to do so.

The fixed part 8 has a sliding surface 2a on which the soft clamper 7a slides forward. In order to fix the ferrule 5 in a correctly positioned state using the pin hole provided in advance for joining the ferrule 5,

■． Next, hold one end of the optical fiber 4 with one hand and set the optical fiber 4 at a predetermined position on the slide surface 2a (see FIG. 4).

■． After that, the soft clamper 7a is pushed down in a predetermined direction to fix the tip of the optical fiber 4, and then the soft clamper 7 is moved along the sliding surface 2a to the left fixing part as shown in FIG. (See Figure 5). In this way, the core wire at the tip of the optical fiber 4 can be inserted into the fine hole of the ferrule 5.

■． Next, in this state, the hard clamper 7a is pushed down in a predetermined direction to fix the optical fiber 4 to the core wire insertion jig 2 (see FIG. 5).

■． Then, the entire core wire insertion jig 2 is slid to the left in FIG. 5 on the stage Ia, and set on the insertion port setting table 3.

■． Then, by the sliding movement of the core wire insertion jig 2, the tip of the ferrule 5 is automatically set in the suction port of the suction port setting table 3 (see FIG. 6).

■． When the adhesive 9 is dripped into the hole of the ferrule 5 in this state, the adhesive that has not been dripped inside the ferrule 5 is passed through the communication pipe 3a on the suction port set table 3 side from the suction means in the main body. Since the adhesive 9 is sucked together with air, the fine holes in the ferrule 5 are filled with the adhesive 9.
