Description

Technical Field

[0001] The invention belongs to the technical field of optical cable preparation, and in particular relates to an optical fiber high-speed unwinding and arranging device and an arranging method. Background Art

[0002] Optical cables are manufactured to meet optical, mechanical or environmental performance specifications. They are communications cable assemblies that use one or more optical fibers encased in a protective sheath as a transmission medium, used individually or in groups. Optical cables usually include an optical fiber and an outer sheath structure sheathed on the outside of the optical fiber. Due to the difference in the optical fiber preparation and outer sheath sheathing processes, the preparation of the optical fiber and the sheathing of the optical fiber are usually carried out separately. In order to facilitate the transportation and arrangement of the optical fiber after production, the optical fiber is usually wound and rolled on a reel, and then the rolled optical fiber is transported to the outer sheath preparation site, where the optical fiber is laid out and an outer sheath is prepared around the outer periphery of the optical fiber.

[0003] The process from preparing optical fiber to forming optical cable involves the winding and unwinding of optical fiber. The unwinding of optical fiber involves the production of outer sheath. If the optical fiber fluctuates during the unwinding process, it is easy to make the excess length of optical fiber in the outer sheath difficult to control, affecting the overall production quality of optical cable. The winding in the optical fiber preparation process is difficult to meet the unwinding requirements. Therefore, it is necessary to rewind and rearrange the prepared optical fiber to avoid problems such as unevenness and wire pressing during the optical fiber winding process.

[0004] Existing high-speed optical fiber unwinding and arranging devices mostly use a swing bar or limit sensor to detect the deviation of the optical fiber winding, and adjust the reel position accordingly to achieve high-speed and stable optical fiber unwinding, so as to achieve tight arrangement of the optical fiber. The swing bar sensor mainly limits the position of the optical fiber through the swing bar structure, but in order to ensure that the swing bar can sense the deviation of the optical fiber position, it usually uses a lightweight plastic rod, resulting in poor anti-interference ability, and the swing bar frequently shakes with the vibration of the optical fiber, and the reel cannot be accurately adjusted. The installation method of the limit sensor is relatively cumbersome, and when the optical fiber swings over the limit position, the optical fiber will frequently shake due to the large deviation angle of the optical fiber position, resulting in the limit sensor being unable to effectively identify the deviation direction of the optical fiber and unable to effectively correct the position of the optical fiber, which ultimately affects the tightness of the optical fiber winding.

[0027] Example: See also Figures 1 to 5The high-speed unwinding and arranging device for optical fiber 11 in the preferred embodiment of the present invention includes a base 1, a guide rail 2 arranged on the base 1, an unwinding mechanism is arranged on the guide rail 2, and a displacement motor 3 is arranged on one side of the unwinding mechanism along the direction of the guide rail 2; at the same time, the unwinding mechanism includes a reel placement mechanism and an unwinding motor 6 connected to the reel placement mechanism; a guide wheel 7 is also arranged on one side of the unwinding mechanism, and the wheel surface of the guide wheel 7 is arranged perpendicular to the axial direction of the reel placement mechanism, and a displacement detection mechanism is also arranged between the guide wheel 7 and the reel placement mechanism, and the displacement detection mechanism is used to form a surface light source between the guide wheel 7 and the reel placement mechanism, and the surface light source can generate a position signal of the cable when a cable passes through.

[0028] Specifically, the present application sets a displacement detection mechanism between the guide wheel 7 and the reel placement mechanism, and forms a surface light source between the two through the displacement detection mechanism. By obtaining the position of the optical fiber 11 passing through the surface light source, it is determined whether the optical fiber 11 is offset, jittered, pressed, and the winding thickness, etc., and through non-contact detection of the position of the optical fiber 11, it is ensured that the high-speed unwinding and arranging device of the optical fiber 11 accurately adjusts the position of the optical fiber 11, realizes the stable arrangement of the rewinding of the optical fiber 11, and improves the compactness of the arrangement of the optical fiber 11.

[0029] Specifically, the displacement motor 3 in the present application is used to push the reel 10 to move axially, so that the optical fiber 11 led out from the reel 10 is pulled to the guide wheel 7 in a direction perpendicular to the axial direction of the reel 10, so as to avoid an oblique angle between the optical fiber 11 and the wheel surface of the guide wheel 7, which causes transmission jitter of the optical fiber 11 and affects the accuracy of rewinding the optical fiber 11. The reel placement mechanism is used to place the reel 10 and fix the two ends of the reel 10; it is driven by the displacement motor 3 to reciprocate on the guide rail 2 to achieve the unwinding of the optical fiber 11 on the reel 10. The guide wheel 7 is used to lead out the unwound optical fiber 11, which then passes through the dancing wheel and is finally rewound onto the reel 10 to achieve the rewinding of the optical fiber 11. At the same time, the displacement detection mechanism is used to form a surface light source. When the optical fiber 11 passes through the surface light source, the position of the optical fiber 11 can be fed back. When the unwinding motor 6 and the displacement motor 3 are displaced at the set rate, the optical fiber 11 just passes through the wheel surface of the guide wheel 7 in a straight line; when the optical fiber 11 is not tightly wound, tilted or pressed, the optical fiber 11 will be arranged at an angle to the wheel surface of the guide wheel 7 after passing through the surface light source, thereby causing jitter in the transmission of the optical fiber 11, which not only affects the attenuation loss of the optical fiber 11, but also causes the rewinding arrangement of the optical fiber 11 to be uneven, affecting the subsequent coloring of the optical fiber 11 and the preparation of the optical cable.

[0030] Further, as a preferred embodiment of the present invention, the plate placing mechanism in the present application includes a first bearing seat 4 and a second bearing seat 5 which are arranged opposite to each other, and the first bearing seat 4 and the second bearing seat 5 both extend the support shaft in the direction of the guide rail 2, and the first bearing seat 4 and the second bearing seat 5 are both slidably arranged on the guide rail 2. The support shaft is used to pass the plate 10 to fix the plate 10 on the plate placing mechanism, and the plate 10 is fixed by the plate placing mechanism, and then the unwinding motor 6 drives the plate 10 to rotate, and the displacement motor 3 drives the plate 10 to move along its axial direction.

[0031] Further, as a preferred embodiment of the present invention, the guide rails 2 in the present application are arranged in pairs and spaced side by side, and the above-mentioned plate placing mechanism is slidably arranged on the two guide rails 2, the output shaft of the displacement motor 3 abuts against the plate placing mechanism, and the displacement motor 3 is arranged in the middle position of the gap between the two guide rails 2. The setting of the double guide rails 2 allows the plate placing mechanism to slide smoothly on the guide rails 2, ensuring the precise controllability of the position of the plate 10. Correspondingly, in order to avoid unbalanced force on the plate placing mechanism when the unilateral motor is pushed, the present application correspondingly sets the displacement motor 3 between the two guide rails 2 to ensure that the plate 10 moves stably along the guide rail 2.

[0032] Furthermore, the displacement detection mechanism in the present application includes a light source transmitter 8 and a light source receiver 9. The light source transmitter 8 is used to emit a surface light source and is received by the light source receiver 9. Through the surface light source generated between the light source transmitter 8 and the light source receiver 9, when a cable passes through, the position of the optical fiber 11 is determined by the light source signal and light source intensity received by the light source receiver 9. Specifically, the optical fiber 11 in the present application is a bare optical fiber 11, which is a transparent structure. When the optical fiber 11 passes through the surface light source, the light source irradiates the surface of the optical fiber 11 and diffuse reflection occurs, thereby affecting the light intensity received at the corresponding position of the light source receiver 9. The specific position of the optical fiber 11 can be obtained by the light intensity obtained at the corresponding position. Further, based on the optical fiber 11 high-speed unwinding and arranging device in the present application, the present application also includes a method for high-speed unwinding and arranging the optical fiber 11, which includes the following steps: The reel 10 wound with the optical fiber 11 is placed on the reel placement mechanism, the optical fiber 11 is led out from the reel 10 through the surface light source and pulled to the guide wheel 7, and the optical fiber 11 is led out from the guide wheel 7 and pulled to another reel 10 for rearrangement; The rotation speed of the unwinding motor 6 and the displacement rate of the displacement motor 3 are set respectively; The displacement detection mechanism obtains the position where the optical fiber 11 passes through the surface light source, and controls the rotation of the unwinding and the movement of the displacement motor 3 according to the signal received by the displacement detection mechanism, so that the optical fiber 11 is continuously led out in a direction perpendicular to the axis of the reel 10.

[0033] Specifically, when the optical fiber 11 in the present application is wound relatively neatly, the reciprocating unwinding of the optical fiber 11 on the reel 10 can be achieved by following the set rotation speed of the unwinding motor 6 and the moving speed of the displacement motor 3, and then the optical fiber 11 is led out from the guide wheel 7, passes through the dancing wheel, and finally is wound again on another reel 10, so as to achieve the rewinding of the optical fiber 11. Correspondingly, when the optical fiber 11 is wound loosely, pressed, or tilted seriously on the reel 10, the optical fiber 11 will enter the guide wheel 7 at an oblique angle after passing through the surface light source, and the position of the optical fiber 11 on the surface light source will also change accordingly. By capturing the position of the optical fiber 11 on the surface light source, the rotation speed of the unwinding motor 6 and the displacement speed of the displacement motor 3 are adjusted accordingly to achieve the position adjustment of the reel 10, so as to ensure that the optical fiber 11 on the reel 10 is continuously led out in a direction perpendicular to the axis of the reel 10.

[0034] Further, as a preferred embodiment of the present invention, the displacement motor 3 in the present application controls the movement of the displacement motor 3 according to the signal received by the displacement detection mechanism, specifically including: The displacement detection mechanism forms a rectangular surface light source between the guide wheel 7 and the plate 10, the axial direction of the plate 10 is set as the first direction, and the direction of the rectangular surface light source perpendicular to the first direction is set as the second direction; Acquire the position of the optical fiber 11 in the first direction; A first limit point and a second limit point are set in the first direction, and when the optical fiber 11 is located between the first limit point and the second limit point in the first direction, the displacement motor 3 is displaced at a set rate; When the optical fiber 11 is located at the side of the first limit point away from the second limit point in the first direction, the displacement motor 3 moves from the first limit point to the direction of the second limit point; when the optical fiber 11 is located at the side of the second limit point away from the first limit point in the first direction, the displacement motor 3 moves from the second limit point to the direction of the first limit point until the optical fiber 11 is located between the first limit point and the second limit point. In addition, when the position of the optical fiber 11 is offset to outside the first limit point and the second limit point, the displacement motor 3 performs displacement adjustment at the first displacement rate, and the first displacement rate is greater than the set rate of the displacement motor 3. When the optical fibers 11 are closely arranged, the optical fibers 11 are wound on the reel 10. When the reel 10 rotates one circle, the optical fibers 11 are released one circle, and the optical fibers 11 correspondingly move along the axial direction of the reel 10 by a displacement of one optical fiber 11 diameter. By matching the rotation speed of the unwinding motor 6 and the displacement rate of the displacement motor 3, the optical fiber 11 is led out perpendicular to the axial direction of the reel 10.

[0035] When the optical fiber 11 is not arranged tightly on the reel 10 or is tilted too seriously, the optical fiber 11 will have a large offset along the axial direction of the reel 10 after unwinding one circle. When the offset of the optical fiber 11 is serious, it is easy to cause the transmission jitter of the optical fiber 11, affecting the subsequent rewinding of the optical fiber 11. At this time, it is necessary to quickly adjust the displacement of the reel 10 along the axial direction to reduce the offset of the optical fiber 11 and ensure the stable unwinding of the optical fiber 11. Based on this, the present application sets the first limit point and the second limit point. When the displacement of the optical fiber 11 is between the first limit point and the second limit point, it proves that the offset angle of the optical fiber 11 is small, which can ensure the stable traction of the optical fiber 11. At this time, the unwinding output can be performed according to the set program; when the optical fiber 11 falls outside the first limit point and the second limit point, it proves that the offset of the optical fiber 11 is serious, and it is necessary to adjust the position of the reel 10 in the opposite direction to reduce the lead-out inclination angle of the optical fiber 11 and ensure the stable lead-out of the optical fiber 11. Correspondingly, when the optical fiber 11 has a large displacement, the position adjustment of the tray 10 needs to be quickly intervened, so it is necessary to quickly adjust at the first displacement rate to quickly pull the optical fiber 11 into the position between the first limit point and the second limit point.

[0036] It is worth noting that the first limiting point and the second limiting point in the present application can be adjusted according to the actual arrangement rate of the optical fiber 11, so as to ensure the normal arrangement of the optical fiber 11.

[0037] Further preferably, the displacement motor 3 in the present application controls the movement of the displacement motor 3 according to the signal received by the displacement detection mechanism, and further includes: The position of the optical fiber 11 in the first direction is obtained. When the optical fiber 11 moves back and forth in the first direction, the center position of the reciprocating movement of the optical fiber 11 in the first direction is obtained. When the center position is close to the first limit point, the displacement motor 3 moves from the first limit point toward the direction of the second limit point; when the center position is close to the second limit point, the displacement motor 3 moves from the second limit point toward the direction of the first limit point; wherein, the displacement motor 3 performs displacement adjustment at a second displacement rate, and the second displacement rate is greater than the first displacement rate.

[0038] When the offset of the optical fiber 11 is too large, the optical fiber 11 will interfere with the disk surface of the guide wheel 7, and the high-speed unwinding of the optical fiber 11 will cause high-frequency vibration of the optical fiber 11. At this time, the optical fiber 11 will frequently move left and right, that is, high-frequency reciprocating movement in the first direction, making it difficult to determine which side the optical fiber 11 is offset to. At this time, the center position of the optical fiber 11 that moves back and forth in the first direction can be obtained. When the center position is close to the first limit point, it proves that the optical fiber 11 is offset to one side of the first limit point. At this time, the reel 10 is moved to the second limit point; when the center position is close to the second limit point, it proves that the optical fiber 11 is offset to one side of the second limit point. At this time, the reel 10 is moved to the first limit point to correct the output position of the optical fiber 11. Correspondingly, when the optical fiber 11 frequently shakes, it proves that the offset of the optical fiber 11 is large. At this time, it is necessary to quickly adjust the position of the reel 10 at the second displacement rate to achieve normal unwinding output of the optical fiber 11.

[0039] Specifically, the acquisition of the position of the optical fiber 11 in the first direction in the present application specifically includes: the light source receiver 9 receives the light source emitted by the transmitter of the optical fiber 11, and obtains the weak point of the light source in the first direction, and the weak point of the light source in the first direction is the position of the optical fiber 11 in the first direction. As shown above, the optical fiber 11 in the present application is a bare optical fiber 11. When the optical fiber 11 is blocked at the surface light source, the light source emitted by the transmitter of the optical fiber 11 hits the surface of the optical fiber 11, and the light source is diffusely reflected on the surface of the optical fiber 11, resulting in a decrease in the intensity of the light source received by the light source receiver 9 (the weak point of the light source). By obtaining the position where the intensity of the light source received by the light source receiver 9 is reduced, the position of the optical fiber 11 in the first direction can be obtained, and by comparing the positional relationship between the position of the optical fiber 11 and the first limit point and the second limit point, the offset of the optical fiber 11 can be obtained.

[0040] Furthermore, in the present application, the unwinding motor 6 controls the speed of the unwinding motor 6 according to the signal received by the displacement detection mechanism, specifically including: The displacement of the optical fiber 11 in the second direction is obtained, and the winding thickness of the optical fiber 11 on the reel 10 is obtained according to the displacement of the optical fiber 11 in the second direction, and the speed of the unwinding motor 6 is adjusted according to the pay-off rate of the optical fiber 11. Specifically, since the thickness of the optical fiber 11 wound on the reel 10 is relatively high, when the winding thickness of the optical fiber 11 on the reel 10 is different, the speed of the unwinding motor 6 needs to be adjusted accordingly to achieve the output of the optical fiber 11 at a constant linear speed. When the output point of the optical fiber 11 is at different thicknesses, the height of the optical fiber 11 is also different accordingly. By obtaining the height of the optical fiber 11 in the second direction, the winding thickness of the optical fiber 11 can be obtained accordingly, and the speed of the unwinding motor 6 is adjusted accordingly to achieve the output of the optical fiber 11 at a constant linear speed.

[0041] Further, as a preferred embodiment of the present invention, in the present application, obtaining the position of the optical fiber 11 in the second direction specifically includes: The light source receiver 9 receives the light source emitted by the light source transmitter 8, and obtains the light intensity of the light source receiver 9; the position of the optical fiber 11 in the second direction is obtained according to the light intensity received by the light source receiver 9. As shown above, the optical fiber 11 in the present application is a bare optical fiber 11. When the light source is irradiated on the optical fiber 11, diffuse reflection will occur. At this time, the light intensity received by the light source receiver 9 will be correspondingly weakened. When the position of the optical fiber 11 is different, the distance of diffuse reflection of the light at the optical fiber 11 is correspondingly different, and the light intensity received by the light source receiver 9 is also correspondingly different, so that the position of the optical fiber 11 in the second direction can be obtained. By obtaining the light intensity of the optical fiber 11 from the innermost to the outermost side when it is wound on the reel 10, the light intensity received by the light source receiver 9 can be matched to correspond to the winding thickness of the optical fiber 11 on the reel 10 at this time.

[0042] Further, as a preferred embodiment of the present invention, the detection of the position of the optical fiber 11 by the displacement detection mechanism in the present application also includes: The displacement of the optical fiber 11 in the second direction is obtained. When the optical fiber 11 moves back and forth in the second direction, the maximum amplitude of the reciprocating displacement of the optical fiber 11 in the second direction is obtained. When the maximum amplitude is not greater than the set amplitude, the rotation speed of the unwinding motor 6 and the displacement rate of the displacement motor 3 are controlled at the set rate; when the maximum amplitude is greater than the set amplitude, the optical fiber 11 attenuates and the high-speed unwinding of the optical fiber 11 is stopped. In the unwinding process of the optical fiber 11, in addition to the conventional offset and jitter, there is also line pressing. When the optical fiber 11 is pressed by the outer optical fiber 11, pulling the optical fiber 11 off the reel 10 will cause the optical fiber 11 to jitter along the second direction. Even when the optical fiber 11 is pressed by multiple layers of optical fibers 11, forcibly pulling the optical fiber 11 off the reel 10 will cause fiber breakage or optical fiber 11 attenuation and loss. Therefore, the present application sets the jitter amplitude in the second direction, that is, the maximum amplitude of the reciprocating displacement in the second direction. When the jitter of the optical fiber 11 exceeds the maximum amplitude of the reciprocating displacement in the second direction, it proves that the optical fiber 11 has an attenuation loss problem, and the winding of the optical fiber 11 is relatively disordered. At this time, it is necessary to stop the high-speed unwinding of the optical fiber 11, manually judge the winding condition of the optical fiber 11, and avoid continuous attenuation loss of the optical fiber 11 by reducing the unwinding rate or manually unwinding part of the optical fiber 11.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
