【発明の詳細な説明】 〔産業上の利用分野〕 本発明は光ファイバー接続端面研磨装置に関する。[Detailed description of the invention] [Industrial application field] The present invention relates to an optical fiber connection end face polishing device.

。BACKGROUND ART In recent years, optical communication systems using optical fibers have been rapidly progressing, but an important issue in this type of optical communication system is how to reduce the loss of light transmitted by the optical fibers. In order to reduce the loss of light at the connecting portion when optical fibers are connected, the end faces must be brought into accurate contact with each other so that optical axis deviation and optical axis tilt at the connecting portion are minimized as much as possible.

ァイバーの端面同士がより確実に当接するようにするた
めに、接続端面ば球面状に研磨される。For this purpose, conventionally, a male connector called a ferrule is attached to each connecting end of the optical fibers to be connected, and the tip of this ferrule is inserted and fixed into a female connector for connection from both sides, and one end of the optical fiber supported by the ferrule is mutually connected. In order to ensure that the end faces of the optical fibers come into contact with each other more reliably, the connecting end faces are polished into a spherical shape.

いる。Conventionally, as a polishing device for polishing the connection end surface of an optical fiber with a ferrule attached into a spherical shape, an elastic material such as rubber is spread on the surface of a rotating plate, and a polishing plate coated with an abrasive material such as diamond paste is used. The polishing plate used is configured to rotate and press the optical fiber connection end face held by the chuck against the surface of the rotating polishing plate, and perform polishing while rotating the chuck in reverse rotation.

めの良好な球状端面が得難いという問題もあった。[Problem to be Solved by the Invention] Normally, when connecting optical fibers, ferrules are attached to both ends and both ends are polished at the same time. However, in the conventional polishing device described above, both ends are polished at the same time. In this case, stress is applied to the optical fiber due to the reverse rotation of the chuck holding the connection end, which may cause problems such as damage to the optical fiber. In addition, with conventional equipment, the rotation of the chuck is distorted, and the polishing plate is easily distorted and rotated. As a result, the symmetry of the polished end face tends to be poor. There was also the problem that it was difficult to obtain.

動軸５に伝達される。The first drive shaft 4 transmits the power of the motor 12 to a second bevel gear 9 that meshes with a first bevel gear 8 attached to the tip of the shaft of the motor 12, and is coaxial with the second bevel gear 9. The first spur gear 10 to the second spur gear II are pivotally connected.
This is further transmitted to and rotated by a third spur gear 34 pivotally connected to the first drive shaft 4. Further, the power transmitted from the motor 12 to the second gear 11 is transmitted from a gear (not shown) coaxially connected to the second spur gear 11 to the fourth spur gear 15. The signal is transmitted from the fifth spur gear 16 coaxially connected to the sixth spur gear 17 pivotally connected to the second drive shaft 5, thereby causing the second drive shaft 5 to rotate. In this way, the power of the motor 12 is transmitted to the first drive shaft 4 and the second drive shaft 5 through separate paths, so that the re-drive shafts 4.5 rotate independently. The first drive shaft 4 and the second drive shaft 5 may rotate in the same direction or in different directions. Further, the ratio of the rotation speeds of the first drive shaft 4 and the second drive shaft 5 is preferably about 1:40 to 100, where the rotation speed of the first drive shaft: the rotation speed of the second drive shaft is about 1:40 to 100. The power from the motor 12 is transmitted to the first drive shaft 4 and the second drive shaft 5 by adjusting the gear ratio of the spur gear as appropriate.

The rotating body 19 is a gear, and is rotated by meshing with a seventh spur gear 21 pivotally attached to the upper end of the first drive shaft 4. On the other hand, a drive transmission shaft 22 is provided on the upper surface of the rotary body 19 in a protruding position eccentrically with respect to the rotation axis 20 of the rotary body 19, and the drive transmission shaft 22 is rotatably attached to the polishing plate 14. supported. still,

によって、研磨板１４は見掛は上、回転運動を行う。When the rotating body 19 is rotated by the energy transmitted from the motor 12 via the first drive shaft 4, the kinetic energy of the rotating body 19 causes the drive transmission shaft 22, which is provided at an eccentric position with respect to the rotating shaft 20, to rotate. Through the polishing plate 14
However, since the polishing plate 14 is configured to move only in the horizontal direction, the energy component of the energy transmitted by the drive transmission shaft 22 is divided in the direction of movement of the polishing plate 14. The polishing plate 14 is indicated by arrow A.
, are slid in the B direction. On the other hand, the polishing plate 14 is configured to be able to slide while being guided by the sliding plate 7, and the sliding plate 7 is configured to horizontally move in a direction perpendicular to the direction of movement of the polishing plate 14. Therefore, of the energy transmitted by the drive transmission shaft 22, the polishing plate 14
The sliding plate is caused to slide by the energy component divided in the direction of motion perpendicular to the direction of motion of . In this way, the polishing plate 14 and the sliding plate 7 move horizontally in directions perpendicular to each other due to the energy transmitted from the rotating body 19 to the polishing plate 14 and the sliding plate 7, but by combining the stomach movements, The polishing plate 14 appears to perform a rotational movement.

回転体１９の回転軸２０を中心として回転（自転）する
のみならず、第２駆動軸５を中心として回転（公転）す
る（第３図参照）。On the other hand, since the rotating shaft 20 of the rotating body 19 is supported eccentrically with respect to the second drive shaft 5, the rotating body 19 rotates (rotates) around the rotating shaft 20 of the rotating body 19. In addition, it rotates (revolutions) around the second drive shaft 5 (see FIG. 3).

磨板１４の回転運動とは回転の中心、回転半径が異なる
ため、研磨板１４は自転しながら公転する如き運動を行
う。The energy of the revolution of the rotating body 19 about the second drive shaft 5 is also transmitted to the polishing plate 14 and the sliding plate 7 in the same manner as described above, so that the polishing plate 14 and the sliding plate 7 slide, respectively. The polishing plate 14 apparently rotates upward due to the combination of both movements, but the apparent rotational movement of the polishing plate 14 due to the above-mentioned rotational movement of the rotating body 19 and the rotational movement of the rotating body 19 cause the polishing plate 14 to rotate upward. Since the center of rotation and radius of rotation are different from the rotational movement of polishing plate 14, polishing plate 14 performs a movement as if it revolves while rotating on its own axis.

Insert. A recessed notch 30 is provided on the periphery of the flange 29 of the ferrule 26, and on the other hand, the support base 24 has a protrusion 31 that fits into the recessed notch 30 provided in the flange 29 of the ferrule 26. Two ferrule fixing plates 32 are provided so that they can approach and separate from each other across the ferrule tip insertion hole 25, and after the tip 28 of the ferrule 26 is inserted into the ferrule tip insertion hole 25, the ferrule is fixed. Convex portion 3 of plate 32
1 is fitted into the recessed notch 30 of the flange 29 of the ferrule, thereby preventing rotation of the ferrule during polishing. In addition, in Figures 1 and 3, 33
is a weight, and the load of this weight ensures that the connecting end surface of the tip 28 of the ferrule 26 comes into contact with the polishing plate and is polished.

の効果を有する。As explained above, when the polishing device of the present invention polishes the connection end face of an optical fiber, the optical fiber side is polished while being fixed, so it is different from the conventional polishing device that polishes the optical fiber side while rotating it in reverse. Furthermore, there is no possibility of uneven polishing due to rotational distortion of the chuck. Further, since the polishing apparatus of the present invention is configured so that the polishing plate is rotated by a combination of the horizontal movement of the polishing plate and the horizontal movement of the sliding plate in a direction perpendicular to the polishing plate, the polishing plate is rotated. Since there is no risk of distorted rotation and the polishing plate and the connection end surface of the optical fiber can always be in contact at a constant angle, there is no risk of the connection end surface being polished unevenly. Furthermore, since the polishing plate is designed at the bottom so as to perform a compound rotational movement that is a combination of rotational movement and revolution movement, it has the effect that the connecting end face of the optical fiber can be polished into a good spherical shape.
