Abstract
The invention discloses an on-line adaptive optical fiber coupling device, which comprises a fixed bent block and a movable bent block. The fixed bent block and the movable bent block are matched with each other to form an optical fiber clamping port. When the movable bent block moves towards the fixed bent block, an optical fiber is bent. A drive unit drives the movable bent block to move. A position sensor acquires the location of the movable bent block. A control module acquires and sends out processing signals. According to the invention, the device can be applied to all kinds of optical fibers. In this way, not only optical fibers are prevented from being pinched off, but also required optical signals can be coupled. Meanwhile, the device is convenient to use.

Embodiment
Embodiment:
Consult Fig. 1, a kind of online adaptive optic fiber coupling device, comprises fixed bend knee-piece 1 and active bending block 2; Fixed bend knee-piece 1 matches with active bending block 2 formation optical fiber clamping mouth 10, and fixed bend knee-piece 1 has protuberance 11, and active bending block 2 has the depressed part 12 suitable with this protuberance 11.Its vertical cross-section of protuberance 11 is arc towards the side of active bending block 2, and the optical fiber curvature radius of this arc is greater than 30mm.Optical fiber is placed in clamp port 10, when the moving towards fixed bend knee-piece 1 of active bending block 2, makes fibre-optical bending;
Driver element 3, orders about active bending block 2 and moves; Driver element 3 is preferably stepper motor.Stepper motor is opened loop control unit stepper motor part electric impulse signal being changed into angular displacement or displacement of the lines.When non-overload, the rotating speed of motor, the position of stopping only depending on frequency and the umber of pulse of pulse signal, and not by the impact of load change, when step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction of setting, be called " step angle ", its rotation runs step by step with fixing angle.Pilot angle displacement can be carried out by gating pulse number, thus reach the object of accurately location; Speed and the acceleration of electric machine rotation can be controlled simultaneously by gating pulse frequency, thus reach the object of speed governing.Because it is because the precision often walked is three to percent five percent, and thus the accumulation of error of a step can not there be is the repeatability of good positional precision and motion to next step; Therefore be used in the displacement that the present invention accurately can control active bending block 2, and make the extruding force of active bending block 2 optical fiber just right, both can fibre-optical bending, but be unlikely to by pinch off.
Position transducer 4, preferred linear displacement transducer, the function of linear displacement transducer is that a straight line mechanical displacement converts electric signal to.In order to reach this effect, usually by the fixed position of variable resistor slide rail fixation at sensor, measure different resistances by the displacement of slide plate on slide rail.Sensor slide rail connects steady-state DC voltage, allows the small area analysis flowing through micromicroampere, the voltage between slide plate and top, is directly proportional to the length of slide plate movement.Sensor is used as voltage divider and can reduces requirement to the total resistance accuracy of slide rail to greatest extent, because the change in resistance caused by temperature variation can not have influence on measurement result.Position transducer 4 is for obtaining the position of active bending block 2; Record protuberance 11 and depressed part 21 air line distance bottom in advance, position transducer 4 can be directly arranged on active bending block 2, obtain the advance displacement of active bending block 2, then can judge the distance between protuberance 11 and depressed part 12, thus judge that whether fixed bend knee-piece 11 and active bending block 12 are by fiber gripper; Another kind of design attitude sensor 4 is located on driver element 3, by measuring the rotating speed of driver element 3, thus indirectly obtain the displacement of active bending block 2, thus judge active bending block 2 and fixed bend knee-piece 1 whether grip optical fibers, thus under active bending block 2 with the state of fixed bend knee-piece 1 grip optical fibers, be coupled out the light signal of needs.
Control module 5, is connected with stepper motor 3 and position transducer 4, and control module 5 first sends certain umber of pulse, Driving Stepping Motor 3 rotates, and drives active bending module 2 to move, position sensing, the physical location of 4 acquisition active bending modules 2, by change in location information feed back to control module 5; Control module 5, according to the change in location information of the umber of pulse sent and feedback, judges whether optical fiber clamps, to realize self-adaptation, guarantees optical fiber not by pinch off, and be coupled out the light signal of needs.
Adopt an application process for above-mentioned online adaptive optic fiber coupling device, comprise the steps:
S1: optical fiber is placed in optical fiber clamping mouth;
S2: control module sends the umber of pulse of predetermined number, makes driver element drive active bending module to move towards fixed bend knee-piece; Position transducer obtains the physical location of active bending module, and by change in location information feed back to control module;
The feedback signal of S3: control module S2 sends the change in location information of corresponding umber of pulse and feedback, judge optical fiber whether be fixed curved block and active bending block clamping, if be judged to be clamping, be then coupled out the light signal of needs.
