[Prior art]

 The automatic polishing machine for an optical connector of this type that has been proposed has the structure shown in FIGS. 4 to 7.

That is, in FIGS. 4 to 7, a pillar 2 is vertically installed at the center of a flat base 1 having a box shape, and a disc-shaped upper portion 2 a of the pillar 2 is provided. The fixed plate 3 is horizontally mounted. A plurality of cylinder devices 4 are provided upside down on the outer peripheral edge portion 3a of the fixed plate 3 with a constant pitch interval, and each output shaft 4a of each cylinder device 4 is provided. The disk-shaped contact plates 5 are horizontally attached to the fixed plate 3 so as to penetrate therethrough. Further, a disc-shaped intermittent rotating body 6 is rotatably loosely fitted to the support column 2 below the fixed plate 3, and the intermittent rotating body 6 is, for example, a pulse motor. An output shaft 7a of the drive motor 7 is coaxially connected to the support 2, and the drive motor 7 is attached to the back surface of the base 1. Further, as shown in FIGS. 5 and 7, the drive motor 7 intermittently rotates the intermittent rotating body 6 by an angle α over each polishing device 15 and each cleaning device 16 described later. At the same time, the drive motor 7 is used to reciprocate the optical connector W attached to the intermittent rotating body 6 by reciprocating for a certain period of time at an angle β slightly smaller than the diameter of the polishing disk 15a of each polishing device 15 for polishing. Is controlled by a program operation by a control circuit (not shown).

On the other hand, as shown in FIG. 6, each floating rod 8 is attached to each coil spring 9 in each through hole 6 a of the intermittent rotary body 6 just below each contact plate 5 in each cylinder device 4. The contact rollers 10 are attached to the upper portions of the floating rods 8 so as to contact the contact plates 5. Further, each flange 8a is formed in the middle of each floating rod 8, and each floating rod 8 at which this flange 8a is located is provided with an angled movable gripping member 11 for each floating rod 8. It is loosely fitted so as to regulate the levitation of the. Further, each sliding guide portion 11a is vertically formed inside the lower end portion of each movable gripping member 11, and each sliding guide portion 11a is attached to each of the intermittent rotating bodies 6. The linear bearing 12 is provided so as to abut and slide. Furthermore, a load adjusting spring 13 is provided between the intermittent rotating body 6 and each movable gripping member 11 beside each linear bearing 12 so as to adjust the load by an adjusting screw rod 14. The adjusting spring 13 urges each movable gripping member 11 to be adjusted to a weak force due to its own weight and to be pushed down when the cylinder device 4 is actuated to push down the floating rod 8. Further, on the outside of the lower end portion of each movable gripping member 11, each gripping portion 11b having an L-shape is attached so as to insert and fix an optical connector W as an object to be polished. As shown in FIGS. 4 and 5, each polishing device 15 and each cleaning device 16 provided with each rotary polishing plate 15a are alternately installed on the base 1 on the rotary passage of the connector W, The cleaning device 16 is preferably a cleaning means such as an ultrasonic cleaning device. Further, as shown in FIG. 4, in the vicinity of each rotary polishing plate 15a of each polishing device 15, an injection nozzle 17 of abrasive having a different particle size is attached. The rotating polishing plate 15a is sprayed with a certain amount of abrasives having different particle sizes.

On the other hand, as shown in FIG. 4, a pair of supporting rods 18 are planted on both sides of the base 1, and horizontal holding rods 19 are mounted on the upper portions of both supporting rods 18. It is equipped. A plurality of fishing fittings 20 are attached to the horizontal holding rod 19 so as to temporarily hold the optical fibers W1 of the optical connectors W. In the middle of the horizontal holding rod 19, A cable connector 21 is provided so as to pass through the optical connectors W so as to bundle them.

As shown in FIG. 5, on the base 1 on the rotation path of the optical connector W, the polishing devices 15 having the rotary polishing plates 15 a and the cleaning devices 16 are alternately installed. However, the first polishing device 15 (I) uses a coarse-grained abrasive, the second polishing device 15 (II) uses an intermediate coarse-grained abrasive, and the third polishing device 15 (I) (III) uses a fine-grained abrasive, fourth abrasive 15 (IV) uses an even finer abrasive, and fifth abrasive 15 (V) uses a finished abrasive. It is designed to be used.

Therefore, the above-mentioned optical connector automatic polishing machine preliminarily inserts and fixes each ferrule W2 of each optical connector W from the cable connector 21 into each gripping portion 11b of each movable gripping member 11. .

Next, when the drive motor 7 is driven by a program operation by a control circuit (not shown), as shown in FIGS. 5 and 7, the intermittent rotating body 6 is applied to each polishing device 15 and each cleaning device 16. The optical connector W attached to the intermittent rotating body 6 is reciprocally rotated on the polishing disk 15a of each polishing device 15 at the angle β for a certain period of time while rotating and moving intermittently by the angle α. While moving so as to perform polishing, when the intermittent rotating body 6 is intermittently rotated by an angle α across each polishing device 15 and each cleaning device 16, each cylinder device 4 of the fixed plate 3 is individually moved. The contact plates 5 actuate to push down the floating rods 8 integrated with the contact rollers 10 against the elastic force of the coil springs 9. The movable gripping member 11 is above Since the elastic force of each load adjusting spring 13 adjusts to a weak force by the self-weight of each movable gripping member 11 and presses it down, each ferrule W2 of each optical connector W of each gripping part 11b is The optical fiber W1 is abutted on the rotary polishing plate 15a of each of the above polishing devices 15 with a predetermined load while polishing from the rough polishing to the medium polishing and the finish polishing of the mirror surface by reciprocatingly rotating for a predetermined time. Continuously polishing while cleaning and polishing without mixing with other polishing agents.

[0009]

However, in the above-described polishing and pressure bonding device in the automatic polishing machine for an optical connector, each cylinder device 4 of the fixed plate 3 is actuated to cause each contact plate 5 to contact each contact roller. Each of the floating rods 8 integrated with 10 is pushed down against the elastic force of each coil spring 9, and each movable gripping member 11 fitted on each floating rod 8 is pushed by the elastic force of each load adjusting spring 13 Since the movable gripping member 11 is biased so as to be pressed down after being adjusted to a weak force by its own weight, the end face of the optical connector is brought into contact with the rotary polishing plate 15a of each polishing device 15 and rough polishing to medium polishing and Although the finish polishing of the mirror surface is theoretically effective, in actuality, not only the sufficient polishing force cannot be obtained simply by adjusting the movable gripping member 11 to a weak force due to its own weight and pressing it down, but Connector The end face of the chromatography is difficult to abut perpendicularly to said rotating polishing plate 15a.

The present invention has been made in view of the above-mentioned circumstances, and holds the end face of the optical connector with an effective and appropriate polishing force, and makes the end face of the optical connector vertically contact the rotary polishing plate, It is an object of the present invention to provide a polishing and pressure bonding device for an optical connector, which is capable of highly accurate polishing.
