Abstract
The present invention discloses a rotating and twisting device of an optical fiber image inverter which is a device with braking function, simplicity and practical utility, thus realizing rotational heating and twisting of the optical fiber composite silk rod from beginning to end, overcoming the defects of uneven heating, easy cracking and severe distortion due to falling deviation of a workpiece in an ordinary twisting method of an optical fiber image inverter, and dramatically enhancing the qualified rate of the product quality. The device has the advantages of simplicity, practical utility, low cost of manufacture and easy operation.
Description
Technical field
The present invention relates to fiberoptic a kind of biography as the device manufacturing technology, say so more specifically about the system of the turning round device of optical fiber image inverter.
Background technology
Optical fiber image inverter is to turn round the biography that forms of system as device by the tens million of optical glass fibres that are less than or equal to 6 microns through regularly arranged fusion pressure, and it can be with the image of input around its axis Rotate 180 ° output, thereby becomes the picture of handstand.It is particularly one of the core parts of gleam image intensifier of new generation of photoelectric instrument, is widely used in fields such as medical treatment, night vision.
The manufacture method of optical fiber image inverter, general elder generation becomes an Optical Fiber Composite silk rod with optical fiber through regularly arranged, fusion pressure, heats the system turned round again and form on isolated plant.After turning round system, an end of every optical fiber in the composite filament rod all must be around the accurate Rotate 180 of composite filament rod central axis ° (removing one at center), and can not misplace and burst.
For making optical fiber image inverter, usually the twisting method and the device of design or use mainly contain two kinds: the one, and the horizontal clamping of Optical Fiber Composite silk rod is on the diaxon of turning round the system machine, and remain static from start to finish and in heating furnace, heat, when treating that composite filament rod middle part begins to soften, then rotate one with weight pulling mode, other one maintains static or rotates by reverse direction, till windup-degree reaches requirement.This twisting method and device are simple, angle control is easier, but because furnace temp is difficult to accomplish uniformity all around, the composite filament rod that causes horizontal stationary the to be placed inequality of being heated, local because of being subjected to gravity effect to be easy to generate " tenesmus skew " in the thermoplastic process, these two kinds of shortcomings often make that composite filament rod stress in turning round system or temperature-fall period is excessive to burst or make optical fiber to produce dislocation, distort; The 2nd, install a motor on the system machine additional aforementioned turning round, allow its drive shaft drive composite filament rod and before heat temperature raising is not softening, rotate and be heated, this helps to improve the composite filament rod uneven phenomenon of being heated.But this mode begins at composite filament rod middle part when softening, stop motor and rotate to use instead and hang weight and increase torsion the composite filament rod is twisted under the temperature of not destroying fiber.The composite filament rod has to stop the rotation and static being heated beginning to turn round to make in the long-time pyroprocess that the system turned round finishes like this, and the composite filament rod is heated uneven and " tenesmus skew " phenomenon still may take place, and product quality is difficult to guarantee.
Summary of the invention
The present invention is intended to overcome the deficiency and the defective of above-mentioned optical fiber image inverter twisting method and device, provides a kind of simple and effective optical fiber image inverter to rotate and turns round the system device, and optical fiber image inverter product quality qualification rate is improved.
The present invention is realized by the following technical programs:
A kind of optical fiber image inverter rotates and turns round the system device, comprises frame, motor, main shaft, driven axle, heating furnace, clamping device and angle scale.The central axis that is installed on main shaft on the frame and driven axle is on same horizontal line, and motor links to each other with main shaft.Clamping device is made up of support, belt and weight, and belt is wound on the driven axle, and belt one end hangs weight, and the other end is right after with the support that is fixed on the frame.Described angle scale is two disks, and they are set with is fixed on main drive shaft and the driven axle, is carved with 0 °～360 ° angle line on the disk.When turning round the system optical fiber image inverter, at first Optical Fiber Composite silk rod is between the main shaft and driven axle that horizontality is clamped in this device, and be placed in the heating furnace, actuating motor and heating furnace then, make Optical Fiber Composite silk rod ceaselessly rotate heating around the central axis of self, driven axle all keeps in various degree rigidity from start to finish owing to be clamped in Optical Fiber Composite silk rod between main drive shaft and the driven axle, so during the rotation of driven by motor main shaft, also will be followed rotation.When treating that composite filament rod middle part reaches transition temperature, the belt of clamping device is wound on the driven axle, at this moment belt and driven axle produce friction force, and damping driven axle rotation leniently makes the driven axle rotating speed lag behind main shaft gradually, thereby affects the composite filament rod to reverse.When going to its start index, staggers mutually 180 ° the time angle scale that is set in main shaft and driven axle, then disable motor stall and to the Optical Fiber Composite silk rod that has reversed the cooling of slowly lowering the temperature, Optical Fiber Composite silk rod is made the optical fiber image inverter of 180 ° of image transfer reversings the most at last.
The present invention is in rotary state when having realized the heating of composite filament rod and having turned round system from start to finish, has therefore avoided workpiece to be heated inhomogeneous and " tenesmus skew " phenomenon, has greatly improved the qualification rate of quality such as product windup-degree, snakelike distortion.
Apparatus of the present invention are simple and practical, low cost of manufacture, operation easily.

Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
According to optical fiber image inverter principle illustrated in Figure 1, for making optical fiber image inverter, at first thousands of optical fiber multifilament are become an Optical Fiber Composite silk rod through regularly arranged, fusion pressure, be placed on then and heat the system of turning round on the isolated plant.Isolated plant is with reference to Fig. 3 and the described assembling of front summary of the invention, and wherein the support 9 of clamping device is fixed on the twin columns of frame 3, and motor 1 drives main shaft 4 rotations by belt.As Fig. 2, Fig. 3, Φ 20mm * 30mm Optical Fiber Composite silk rod 6 horizontalitys are clamped between main shaft 4 and the driven axle 7, be placed on then in the heating furnace 5, and two angle scales, 2 corresponding start index about adjusting and write down well.
Actuating motor 1 and heating furnace, motor then drive main axis rotation, and before Optical Fiber Composite silk rod does not reach transition temperature, Optical Fiber Composite silk rod and driven axle will be followed main shaft and be rotated synchronously, and the composite filament rod of rotation obtains sufficient thermally equivalent in heating furnace.When composite filament rod middle part reaches 620 ℃ of transition temperatures; then the belt 8 with clamping device is wound in a circle on the driven axle; and hang up 2kg weight 10; friction produces a kind of gentleness damping force stably by belt and driven axle, makes the rotating speed of driven axle lag behind the rotating speed of main shaft gradually, and at this moment Optical Fiber Composite silk rod begins generation and reverses; when about the start index of two angle scales stagger 180 ° the time; then shut down stall, and the composite filament rod cooling of having reversed is cooled off, finish the system of turning round of optical fiber image inverter.
