Due to the influence of gravity, the existence torque of the guide wheel assembly relative to the rotating assembly enables the gravity center of the guide wheel assembly to move when the winding rotates, and further leads to unstable optical fiber tension. When the tension required by winding is large, the influence of gravity center movement on the tension of the optical fiber can be ignored when the guide wheel assembly rotates in a winding mode. However, when the tension required for winding is small, the gravity center of the guide wheel assembly moves when the winding rotates, and a force is generated on the optical fiber wound around the guide wheel assembly, so that the tension of the optical fiber cannot reach the small tension, and therefore, the winding requirement of low tension cannot be met.
Referring to fig. 1 to 3, an embodiment of the present application provides a winding device for online tension adjustment of an optical fiber, including:
a rotating assembly 1;
the pneumatic control assembly 2 comprises a cylinder 21, a piston assembly 22 connected with the cylinder 21 and a pressure regulating valve 23, the piston assembly 22 is movably connected with the rotating assembly 1, and the pressure regulating valve 23 is used for regulating the air pressure in the cylinder 21 so as to regulate the torque applied to the rotating assembly 1 by the piston assembly 22;
the guide wheel assembly 3 is fixedly connected with the rotating assembly 1; the rotating assembly 1 is used for driving the guide wheel assembly 3 to move;
and the counterweight component 4 is fixedly connected with the rotating component 1 and is used for balancing the torque of the guide wheel component 3 relative to the rotating component 1.
In this embodiment, before the air is introduced into the air cylinder 21, the position and the weight of the counterweight assembly 4 are adjusted, so that the rotating assembly 1 can stay at any angle position in the process that the rotating assembly 1 rotates along the axis thereof, and at this time, the counterweight assembly 4 completely balances the torque of the guide wheel assembly 3 relative to the rotating assembly 1.
After the torque is balanced, gas with preset air pressure is introduced into the air cylinder 21, the piston assembly 22 drives the rotating assembly 1 to rotate, and the guide wheel assembly 3 and the counterweight assembly 4 are driven to move together. For example, referring to FIG. 2, the guide wheel assembly 3 is angularly deflected to the left, and the guide wheel assembly 3 is pulled to the right around the optical fiber 5 passing through the guide wheel assembly 3, wherein the torque applied to the rotary member 1 by the pneumatic control assembly 2 and the torque applied to the rotary member 1 by the optical fiber 5 are balanced. The preset air pressure is adjusted by the pressure adjusting valve 23 to drive the piston assembly 22 to reciprocate in the cylinder 21, thereby changing the force applied by the piston assembly 22 to the rotating assembly 1. It will be appreciated that the torque is equal to the product of the force and the moment arm. Since the rotating assembly 1 and the guide wheel assembly 3 are both kept stationary, the torque applied to the rotating assembly 1 by the air control assembly 2 and the torque applied to the rotating assembly 1 by the optical fiber 5 are always balanced with each other. As the force applied to rotating assembly 1 by piston assembly 22 varies, the force applied to guide wheel assembly 3 by fiber 5 also varies accordingly. It will be appreciated that the force applied to the guide-wheel assembly 3 by the optical fibre 5 and the force applied to the optical fibre 5 by the guide-wheel assembly 3 are a pair of interacting forces, and that the tension in the optical fibre 5 is proportional to the force applied to the guide-wheel assembly 3 by the optical fibre 5. When the force exerted by the optical fiber 5 on the guide-wheel assembly 3 changes, the tension of the optical fiber 5 will also change accordingly. In this way, the tension of the optical fiber 5 wound around the guide wheel assembly 3 can be adjusted by adjusting the air pressure in the air cylinder 21 by the pressure adjusting valve 23, thereby realizing stepless adjustment of the tension of the optical fiber. The torque of the guide wheel assembly 3 relative to the rotating assembly 1 is balanced, so that the center of gravity of the guide wheel assembly 3 cannot shift when the winding rotates, the stability of optical fiber tension is guaranteed, and the accuracy of the optical fiber tension is improved. Because the torque of the guide wheel assembly 3 relative to the rotating assembly 1 is completely balanced, the force applied to the optical fiber by the gravity center movement of the guide wheel assembly 3 is eliminated, the winding device for adjusting the optical fiber tension on line can provide more accurate and larger stable tension (for example, more than 15 g), meet the requirement of high tension of a common optical fiber, realize smaller stable tension (for example, less than 15 g), and meet the requirement of low tension of a special optical fiber.
The cylinder 21 may be provided with an intake port 24, and the pressure regulating valve 23 may be provided at the intake port 24 of the cylinder 21, and the gas pressure in the cylinder 21 may be controlled by directly controlling the gas at the intake port 24. The pneumatic control assembly can control the pressure regulating valve 23 to regulate the air pressure in the air cylinder 21 according to set parameters, so as to realize automatic regulation; the operator can also manually control the pressure regulating valve 23 to adjust the air pressure in the air cylinder 21 according to the results of empirical observation or instrumental detection. Further, the pressure regulating valve 23 may be a proportional control valve.
This application is through the moment of torsion in 1 axle center of counter weight component 4 balanced guide pulley subassembly 3 edge rotating assembly, has reduced the gravity of guide pulley subassembly and to the tensile interference of optic fibre, has guaranteed the tensile stability of light, and makes optic fibre tension can reach stable less tension under the control of gas accuse subassembly, satisfies the low tension demand of special type optic fibre. The online stepless adjustment of the optical fiber tension is realized by adjusting the gas pressure.
In one embodiment, the pneumatic control assembly 2 further comprises a tension detection device 25;
the tension detection device 25 is electrically connected with the pressure regulating valve 23; the tension detection device 25 is used for detecting the tension of the optical fiber 5;
the pressure regulating valve 23 is used for regulating the air pressure in the air cylinder 21 to reduce the torque applied to the rotating assembly 1 by the piston assembly 22 when the tension detected by the tension detecting device 25 is greater than the preset tension; and adjusting the air pressure in the air cylinder 21 to increase the torque applied to the rotating assembly 1 by the piston assembly 22 when the tension detected by the tension detecting device 25 is less than the preset tension.
In this embodiment, the tension detection device 25 may be provided in the guide wheel assembly 3, so that the guide wheel assembly 3 rotates around the tension detection device 25, and the tension of the optical fiber 5 can be obtained by detecting the pressure of the guide wheel assembly 3 on the tension detection device. Alternatively, the tension detecting device 25 may be provided at a wire inlet or a wire outlet of the guide wheel assembly 3, and the tension of the optical fiber 5 may be directly obtained by detecting the pressure of the optical fiber 5 on the tension detecting device 25. The pressure regulating valve 23 adjusts the air pressure in the air cylinder 21 according to the tension detected by the tension detecting device 25, drives the rotating assembly 1 to drive the guide wheel assembly 3 to move, and further adjusts the tension of the optical fiber 5, thereby ensuring the stability of the optical fiber tension. Wherein, the tension detecting device 25 can be a tension sensor.
For example, referring to fig. 2 and 3, the rotating assembly 1 is located at one side of the guide wheel assembly 3, and air pressure is supplied into the air cylinder 21 through the pressure regulating valve 23 to push the piston assembly 22 to move up and down in the air cylinder 21, so as to drive the rotating assembly 1 to rotate clockwise or counterclockwise, thereby driving the guide wheel assembly 3 to shift left or right. The idler assembly 3 is biased into position such that the torque applied to the rotating assembly 1 by the air control assembly 2 is balanced with the torque applied to the rotating assembly 1 about the optical fiber 5 passing through the idler assembly 3. At this time, the pressure in the cylinder 21 is adjusted by controlling the pressure regulating valve 23, thereby changing the magnitude of the force applied to the rotating unit 1 by the piston unit 22. Since the guide wheel assembly 3 remains stationary, the force applied by the optical fiber to the guide wheel assembly will change accordingly. It will be appreciated that the force applied to the guide-wheel assembly 3 by the optical fibre 5 and the force applied to the optical fibre 5 by the guide-wheel assembly 3 are a pair of interacting forces, and that the tension in the optical fibre 5 is proportional to the force applied to the guide-wheel assembly 3 by the optical fibre 5. When the force exerted by the optical fiber 5 on the guide wheel assembly 3 changes, the tension of the optical fiber 5 will also change accordingly.
When the tension of the optical fiber 5 detected by the tension detecting device 25 is greater than the preset tension, the air pressure in the air cylinder 21 is reduced by the pressure regulating valve 23, the force applied by the piston rod 222 to the rotating assembly 1 is reduced, the force applied by the optical fiber 5 to the guide wheel assembly 3 is also reduced due to the torque balance, and the tension of the optical fiber 5 is reduced. When the tension of the optical fiber 5 detected by the tension detecting device 25 is less than the predetermined tension, the air pressure in the air cylinder 21 is increased by the pressure regulating valve 23, the force applied by the piston rod 222 to the rotating assembly 1 is increased, the force applied by the optical fiber 5 to the guide wheel assembly 3 is also increased due to the torque balance, and the tension of the optical fiber 5 is increased.
In the embodiment, the tension of the optical fiber 5 is detected in real time by the tension detection device 25, the pressure regulating valve 23 regulates the air pressure in the air cylinder 21 according to the tension of the optical fiber 5, and further regulates the tension of the optical fiber 5, so that the tension of the optical fiber 5 is kept at the preset tension, and the online closed-loop control of the tension of the optical fiber 5 is realized.
In one embodiment, the pneumatic control assembly 2 further comprises:
the air pressure detection device 26, the said air pressure detection device 26 is connected electrically with said pressure regulating valve 23; the air pressure detection device 26 is used for detecting the air pressure in the air cylinder 21;
the pressure regulating valve 23 is used for reducing the air pressure in the air cylinder 21 when the air pressure detected by the air pressure detecting device 26 is greater than a preset air pressure; and, when the pressure detected by the air pressure detecting device 26 is less than the preset air pressure, increasing the air pressure in the air cylinder 21; wherein the preset air pressure is in direct proportion to the preset tension.
In the present embodiment, the pressure regulating valve 23 may also regulate the air pressure in the air cylinder 21 in accordance with the pressure detected by the air pressure detecting device 26. For example, referring to fig. 2, the greater the air pressure in the air cylinder 21, the greater the force the piston rod 222 applies to the rotating assembly 1, and the greater the tension in the optical fiber 5. In order to ensure the tension stability of the optical fiber 5, it is necessary to ensure the air pressure in the air cylinder 21 to be stable. When the air pressure in the air cylinder 21 changes, the air pressure can be rapidly detected by the air pressure detection device 26, and the air pressure in the air cylinder 21 is kept at the preset air pressure through the adjustment of the pressure regulating valve 23, so that the tension of the optical fiber 5 is ensured to be stable.
In one embodiment, the piston assembly 22 includes a piston 221 and a piston rod 222;
the piston 221 is disposed in the cylinder 21, one end of the piston rod 222 is movably connected to the piston 221, and the other end of the piston rod 222 is movably connected to the rotating assembly 1.
In this embodiment, when the piston rod 222 drives the rotating assembly 1 to rotate, the action track of the connecting point between the piston rod 222 and the rotating assembly 1 is an arc with the axis of the rotating assembly 1 as the center of the circle. During the process of driving the rotation assembly 1 to rotate, the angle between the piston rod 222 and the rotation assembly 1 changes continuously, i.e. the angle between the piston rod 222 and the piston 221 also changes continuously. If the piston rod 222 and the piston 221 are fixedly connected, the piston rod 222 can only move linearly up and down, and cannot drive the rotation assembly 1 to rotate. Therefore, in the present embodiment, the piston rod 222 is movably connected to the piston 221, so that the piston rod 222 can realize displacement in multiple directions, and further drive the rotation assembly 1 to rotate.
Specifically, the piston rod 222 and the piston 221 may be movably connected by a ball joint. The angular change of the piston rod 222 is achieved by absorbing or compensating for the lateral displacement of the piston rod 222 in one or more directions by the angular displacement of the sphere.
In the present embodiment, the piston 221 and the piston rod 222 are movably connected to each other, so that the piston rod 222 can be displaced in multiple directions to drive the rotation shaft 11 to rotate.
In an embodiment, the rotating assembly 1 comprises:
one end of the rotating shaft 11 is fixedly connected with the guide wheel assembly 3, and the other end of the rotating shaft 11 is fixedly connected with the counterweight assembly 4;
the driving rod 12, the driving rod 12 is located the intermediate position of rotation axis 11, and with rotation axis 11 is the contained angle setting, the one end of driving rod 12 with rotation axis 11 fixed connection, the other end of driving rod 12 with piston rod 222 swing joint.
In this embodiment, the driving rod 12 is disposed in the middle of the rotating shaft 11, so that the force applied to the rotating shaft 11 by the pneumatic control assembly 2 through the driving rod 12 is equal to the distance between the two ends of the rotating shaft 11, thereby preventing the moment imbalance of the rotating shaft 11 to the guide wheel assembly 3 and the counterweight assembly 4 from affecting the tension of the optical fiber 5. The driving rod 12 is disposed at an angle to the rotation shaft 11 so as to drive the rotation shaft 11 to rotate when the piston rod 222 moves up and down. The angle between the driving lever 12 and the rotation axis 11 may be set to 30 °, 60 °, 90 °, etc., without limitation. Further, an included angle between the driving rod 12 and the rotating shaft 11 may be set to 90 °, so that the force of the piston rod 222 on the driving rod 12 may be fully applied to the rotating shaft 11, and the energy utilization efficiency is improved. The driving rod 12 and the rotating shaft 11 may be movably connected by a ball joint, so that an angle between the driving rod 12 and the piston rod 222 may be changed, thereby implementing the rotation of the driving rod 12 along the axis of the rotating shaft 11.
In one embodiment, the rotating assembly 1 further includes a limiting module 13;
the limiting module 13 is fixedly arranged on the rotating shaft 11; the limit module 13 is provided with a limit opening 133, and the driving rod 12 is fixedly connected with the rotating shaft 11 through the limit opening 133.
In this embodiment, the limiting opening 133 is disposed on the limiting module 13, so that the driving rod 12 can move within the angle range provided by the limiting opening 133. When the piston rod 222 drives the driving rod 12 to move to the limit positions at both sides of the limit opening 133, the piston 221 still has a moving space in the cylinder 21. Meanwhile, in the process, the piston rod 222 is in non-contact collision with the cylinder 21, so that the friction collision loss of the pneumatic control assembly 2 is reduced, and the service life of the pneumatic control assembly 2 is prolonged.
In one embodiment, the limiting module 13 includes:
a mount 131;
a rotating body 132, the rotating body 132 being fixed in the mounting seat 131, the rotating shaft 11 being provided in the rotating body 132, the rotating body 132 being rotatable with respect to the rotating shaft 11;
the mounting seat 131 is provided with a limit opening 133, and the driving rod 12 is fixedly connected with the rotating shaft 11 through the limit opening 133.
In this embodiment, the mounting seat 131 is fixedly mounted on the equipment rack to fixedly support the rotating assembly 1. The mounting seat 131 has rotating bodies 132 at both ends thereof, and the rotary shaft 11 is provided in the rotating bodies 132 and movably connected to the rotating bodies 132 such that the rotary shaft 11 can rotate relative to the rotating bodies 132. The mounting seat 131 is provided with a limit opening 133 to limit the rotation angle of the driving rod 12, so as to avoid the loss caused by collision and contact between the piston 221 and the piston rod 222 and the cylinder 21.
In one embodiment, the rotating body 132 may be a bearing. As shown in fig. 3, bearings are mounted at both ends of the mounting seat 131, and the rotary shaft 11 is mounted in the bearings. The driving rod 12 crosses the center of the rotating shaft 11 and is fixedly connected with the rotating shaft 11 by a fixing device 14 (e.g., a screw nut). The pneumatic control assembly 2 is positioned on the left lower side of the bearing seat.
When the pressure regulating valve 23 increases the air pressure in the air cylinder 21, the piston 221 drives the piston rod 222 to move upward, and the driving rod 12 is driven to rotate clockwise around the rotating shaft 11. After the driving rod 12 rotates to a certain angle, it touches the rightmost side of the limit opening 133 and stops rotating. At this time, the piston 221 is spaced apart from the top of the cylinder 21, and the piston rod 222 is spaced apart from the side of the cylinder 21.
When the pressure regulating valve 23 reduces the air pressure in the air cylinder 21, the piston 221 moves the piston rod 222 downward, which rotates the driving rod 12 in the counterclockwise direction about the rotating shaft 11. After the driving rod 12 rotates to a certain angle, it touches the leftmost side of the limit opening 133 and stops rotating. At this time, the piston 221 is still at a distance from the bottom of the cylinder 21, and the piston rod 222 is still at a distance from the side of the cylinder 21.
The present embodiment can fixedly support the rotating assembly 1 by providing the mounting seat 131, and can rotate the rotating shaft 11 while fixedly supporting the rotating shaft 11 by providing the bearing seat. The limit opening 133 arranged on the mounting seat 131 limits the rotation angle of the driving rod 12, so that the piston 221 and the piston rod 222 are prevented from colliding with the cylinder 21 to generate loss.
In an embodiment, the guide wheel assembly 3 comprises:
the guide wheel fixing piece 31, one end of the guide wheel fixing piece 31 is fixedly connected with the rotating assembly 1;
and a guide wheel 32, wherein the guide wheel 32 is mounted to the other end of the guide wheel fixing member 31 such that the guide wheel 32 can rotate around the other end of the guide wheel fixing member 31.
In this embodiment, the guide wheel 32 is fixedly connected to the rotating assembly 1 through the guide wheel fixing member 31, so that the rotating assembly 1 can drive the guide wheel 32 to shift when rotating. The guide wheel 32 is suspended at the other end of the guide wheel fixing member 31 to buffer the speed difference between the fiber feeding and the fiber collecting, so as to prevent the optical fiber 5 from being too loose or too tight and keep the tension stable.
In one embodiment, idler mount 31 includes an idler connection rod 311 and an idler mounting rod 312. Referring to fig. 2, the rotation shaft 11 is parallel to the z-axis, the guide wheel connecting rod 311 is perpendicular to the rotation shaft 11 in the x-axis direction, and one end of the guide wheel connecting rod 311 is fixedly connected to one end of the rotation shaft 11. Guide wheel mounting rod 312 is perpendicular to guide wheel connecting rod 311 in the y-axis direction and is fixedly connected to the other end of guide wheel connecting rod 311. Idler 32 is mounted on idler mounting bar 312. Thus, when rotating, the rotating shaft 11 can drive the guide wheel 32 to shift left or right through the guide wheel connecting rod 311 and the guide wheel mounting rod 312, thereby adjusting the tension of the optical fiber 5. It is understood that the x-axis, y-axis and z-axis are mutually perpendicular directional axes in space.
In one embodiment, the weight assembly 4 includes:
one end of the counterweight fixing piece 41 is fixedly connected with the rotating assembly 1, and the other end of the counterweight fixing piece 41 extends in a direction far away from the guide wheel assembly 3;
and the counterweight block 42 is arranged on the counterweight fixing member 41, and the counterweight block 42 can move along the counterweight fixing member 41.
In this embodiment, a counterweight 42 with a suitable weight is selected, and the position of the counterweight 42 on the counterweight fixing member 41 is adjusted, so that the torque of the counterweight 42 relative to the rotating assembly 1 is equal to the torque of the guide wheel 32 relative to the rotating assembly 1, so as to balance the torque generated by the self-gravity of the guide wheel 32.
For example, the weight of the weight block 42 may be selected to be consistent with the weight of the guide wheel 32, and in order to avoid the torque difference caused by the machining or assembly error, when the pneumatic control assembly 2 is not ventilated, the position of the weight block 42 on the weight fixing member 41 is adjusted, so that the distance L1 from the center of gravity of the weight block 42 to the axis of the rotating shaft 11 is equal to the distance L2 from the center of gravity of the guide wheel 32 to the axis of the rotating shaft 11. It will be appreciated that the torque is equal to the product of the force and the moment arm. When the weights 42 and the guide wheels 32 have the same weight and the center of gravity of the weights 42 and the center of gravity of the guide wheels 32 are the same as the center of the rotating shaft 11, the torques of the weights 42 and the guide wheels 32 relative to the rotating shaft 11 are equal and opposite. In this way, the weight block 42 balances the torque of the guide wheel 32 relative to the rotating shaft 11, and the rotating shaft 11 can stay at any one angular position without displacement due to its own weight in the process of rotating the rotating shaft 11, thereby avoiding the fluctuation of the tension of the optical fiber 5.
In one embodiment, the weight fixing member 41 includes a weight connecting rod 411 and a weight adjusting rod 412. Referring to fig. 2, the rotation axis 11 is parallel to the z-axis, the weight connecting rod 411 is perpendicular to the rotation axis 11 in the x-axis direction, and one end of the weight connecting rod 411 is fixedly connected to the other end of the rotation axis 11. The counterweight adjusting rod 412 is perpendicular to the counterweight connecting rod 411 in the y-axis direction, and is fixedly connected to the other end of the counterweight connecting rod 411, and the extension direction of the counterweight adjusting rod 412 is opposite to the extension direction of the guide wheel mounting rod 312. The weight block 42 is mounted on the weight adjustment rod 412 and is movable along the weight adjustment rod 412. Thus, the rotating shaft 11 can drive the counterweight block 42 and the guide wheel 32 to move simultaneously through the counterweight connecting rod 411 and the counterweight adjusting rod 412 when rotating, so that the counterweight block 42 can always balance the torque of the guide wheel 32 relative to the rotating shaft 11. It is understood that the x-axis, y-axis and z-axis are mutually perpendicular directional axes in space.
Further, the weight 42 may be disposed in an axial structure or an eccentric structure. When the counterweight block 42 is an eccentric structure, the counterweight adjusting rod 412 and the counterweight connecting rod 411 can be rotatably connected, so that the counterweight adjusting rod 412 can rotate along the axis of the counterweight adjusting rod to change the position of the center of gravity of the counterweight block 42; alternatively, the weight block 42 and the weight-adjusting rod 412 may be rotatably connected, such that the weight block 42 can rotate along the axis of the weight-adjusting rod 412 to change the position of the center of gravity of the weight block 42.
Hereinbefore, specific embodiments of the present application are described with reference to the drawings. However, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present application without departing from the spirit and scope of the application. Such modifications and substitutions are intended to be within the scope of the present application.
