Description
Technical Field
[0001] The invention relates to the technical field of optical fiber testing equipment, in particular to an optical fiber testing equipment with uniform force. Background Art
[0002] Optical fiber is the abbreviation of optical fiber, which is a fiber made of glass or plastic that can be used as a light transmission tool. The principle of light propagation in optical fiber is total internal reflection. In daily life, since the conduction loss of light in optical fiber is much lower than the conduction loss of electricity in wires, optical fiber is used for long-distance information transmission. After the optical fiber is produced, it needs to be sampled and tested for various properties to ensure that its performance meets the standards.
[0003] When existing detection devices fix optical fibers, most of them are fixed by tightening bolts at the connection points. Generally, the bolts need to pass through the inside of the optical fiber. However, this connection method may cause the optical fiber to break or detach due to stress concentration due to uneven force when performing tension or torque tests.

[0009] Furthermore, a telescopic rod is connected to one side of the chassis, and one end of the telescopic rod is connected to a push plate. A connecting spring is connected to the middle of the push plate, and one end of the connecting spring is connected to a force-applying component.
[0010] Furthermore, the force-applying component includes a bottom shell, a cavity, a clamping cavity and an electromagnetic block, one end of the connecting spring is connected to the bottom shell, and a cavity is opened in the middle of the bottom shell, a clamping cavity is arranged on the side of the cavity, and the electromagnetic block is connected in the cavity.
[0011] Furthermore, the force-applying assembly also includes a reset spring and a card block. The reset spring is symmetrically connected in the card cavity, and the other end of the reset spring is connected to the card block. The card block is I-shaped, and one end of the card block is located in the cavity. The card block is elastically connected to the card cavity through the reset spring.
[0012] Furthermore, the force-applying assembly also includes a pushing block, a connecting rod, a socket and an arc groove. A pushing block is provided on one side of the bottom shell, and connecting rods are rotatably connected to both sides of the pushing block. The other end of the connecting rod is rotatably connected to the socket, and an arc groove is provided on one side of the socket.
[0013] Furthermore, the clamping block is slidably connected to the holder through the arc block and the arc groove, and the holder is slidably connected to the slide frame, the limit plate is fitted with the side of the holder, the pushing block is an inverted concave shape, and a pressure sensor is arranged in the pushing block.

[0015] Furthermore, a light strip is connected to the surface of the other side of the chassis, and a crossbeam is arranged above the light strip, and a high-definition probe is arranged on one side of the crossbeam.
[0016] The present invention provides an optical fiber testing device with uniform force, which has the following beneficial effects: when in use, the optical fiber end can be stably clamped and force can be applied to it evenly during tensile testing, thereby avoiding stress concentration that causes optical fiber breakage and affects the test results; after the tensile test is passed, the optical fiber can continue to be subjected to torsion testing and bending testing without transferring the optical fiber to other testing equipment, thereby avoiding damage to the optical fiber during the transfer process that causes inaccurate test results.
[0017] 1. When the present invention is in use, firstly, the two ends of the optical fiber to be detected are placed in the clamp seat, and then the telescopic rod drives the pushing plate to move on the chassis, and then the bottom shell can be driven to move through the connecting spring, so that the bottom shell drives the pushing block to drive the connecting rod to move through the clamping block, and then drives the clamping block to approach the clamping seat through the clamping seat until the clamping block and the clamping seat are clamped, and the limit plate can limit the clamping seat, so that it can only move toward the clamping seat before the clamping block and the clamping seat are clamped, so as to avoid lateral displacement. After the clamping block and the clamping seat are clamped, the limit plate no longer limits the moving direction of the clamping seat. At the same time, the clamping block and the soft pad inside the clamping seat can firmly clamp the end of the optical fiber, and the flexible material of the soft pad can avoid the end of the optical fiber from being broken during clamping. After the clamping is firm, the telescopic rod drives the pushing plate to continue to move, and the connecting spring, the bottom shell, the pushing block and the connecting rod can continue to apply force to the clamping seat. After the restriction of the limit plate is lost, the clamping seat can pass through the clamping seat after being subjected to force. The block and the clamp seat apply axial tensile force to the optical fiber, thereby performing a tensile test on it. Before the optical fiber is broken by the force, the clamp seat continues to apply force to it through the clamp block and the clamp seat without displacement. The connecting spring is compressed as the push plate moves, and the bottom shell continues to apply force to the push block through the clamp block, and the pressure sensor arranged in the push block can detect the magnitude of the force. If the optical fiber is still not broken after the preset value of the force is reached, it means that the optical fiber has passed the tensile test. If the optical fiber breaks before the preset value is reached, it means that the tensile test has not been passed. At this time, the device can be restored to its original state to test the next optical fiber. In summary, during the test, the two ends of the optical fiber can be flexibly clamped to prevent the optical fiber end from being broken by force when fixed, and a tensile test can be performed on it after the clamping is completed. The force is evenly applied to it through the symmetry of the device to prevent the optical fiber from breaking due to concentrated force, resulting in inaccurate test results.
[0018] 2. When the card holder moves, the present invention can drive the slide frame to move synchronously, and the slider can limit the slide frame through the slide rail to prevent the slide frame from deflecting when moving. After the clamp block is engaged with the clamp seat, the slider moves to the end of the slide rail, and the slide frame is restricted and cannot continue to move, so that the slide frame can limit the card holder. After the optical fiber passes the tensile test, the electromagnetic block is energized to suck the card block into the card cavity and compress the reset spring, so that the bottom shell can no longer apply force to the push block through the card block, thereby relieving the axial force of the optical fiber. At this time, the bottom shell is connected to the card holder under the action of the connecting spring. It can pass through the pushing block, and after all tests are completed, the electromagnetic block is powered off, and the card block can rebound and pop out of the card cavity under the action of the reset spring. When the telescopic rod drives the pushing plate to reset, the bottom shell can move together with the pushing plate through the connecting spring, and when the card block contacts the pushing block, it drives the pushing block to move synchronously through the card block, so that the pushing block drives the card seat to move and reset through the connecting rod, and drives the sliding frame to reset, so as to facilitate the next test. In summary, when in use, the device can be adjusted according to the test situation, so as to successfully complete various tests.
[0019] 3. In the present invention, after the bottom shell passes through the pushing block, the telescopic rod continues to drive the pushing plate to move, which can drive the gear rod and the rack to move. When the rack contacts the torsion wheel, the rack can drive the turntable to rotate. When the clamping block is engaged with the clamping seat, the clamping block is also clamped into the turntable through the clamping groove, so that when the turntable drives the soft pad on the inner side of the clamping seat to move, it can also drive the soft pad on the inner side of the clamping block to move through the clamping groove and the clamping block, so that the soft pad on the inner side of the clamping block and the clamping seat moves synchronously inside the clamping block and the clamping seat and drives the optical fiber end to rotate. The racks on both sides of the pushing plate are distributed on its upper and lower sides, so that the racks can drive the torsion wheels on both sides to rotate in opposite directions. The optical fiber is moved to perform an initial torsion test on the optical fiber. If the optical fiber passes the initial torsion test, the optical fiber can be restored after the rack is separated from the torsion wheel, and the turntable and the torsion wheel are reset through the soft pad. Then the telescopic rod continues to drive the push plate to move, so that the toothed rod contacts the toothed ring. The toothed rod drives the base to rotate in the slide groove through the toothed ring, so that the clamp seat and the clamp block can apply force to the optical fiber end to bend the optical fiber, thereby performing a bending test on it. When the optical fiber is bent, because its end is fixed between the clamp seat and the clamp block, the optical fiber will drive the base to slide in the slide groove during the bending process, and drive the clamp seat to slide on the inside of the slide frame. When the base rotates, The clamping block will also drive the arc block to slide in the arc groove, and the holder can limit the clamping block through the arc groove and the arc block to avoid damage caused by excessive bending angle of the optical fiber. When the base moves, the toothed ring can be used to drive the gear rod to move through, and the slot can limit the gear rod to avoid deflection of the gear rod when it moves. If the optical fiber passes the bending test, the telescopic rod drives the push plate to move back, and the gear rod and the rack move synchronously with the push plate. When the gear rod moves back, it can drive the gear ring to reverse, thereby restoring the optical fiber, and the magnetic adsorption between the gear rod and the gear ring can ensure the meshing connection between the gear rod and the gear ring, avoiding the gear rod from being bent and restored during the bending and restoration process of the optical fiber. The rod is separated from the gear ring, making it impossible to bend and restore the optical fiber. After the rack contacts the torsion wheel again, the optical fiber can be reversely twisted by the torsion wheel for a secondary torsion test. During the movement of the cushion, the swivel can limit the cushion through the ring groove to prevent the cushion from deflecting when moving. During the test, the light board illuminates the optical fiber, and the high-definition probe shoots the optical fiber to observe whether the optical fiber will break or have cracks inside during the test. If the optical fiber is intact, it means the test has passed, otherwise it means the test has failed. In summary, after the tensile test is completed, the optical fiber can be torsionally and bent without transferring it. BRIEF DESCRIPTION OF THE DRAWINGS

The engaging block 308 is engaged with the rotating disk 309 through the engaging groove 310. The surface of the chassis 1 is symmetrically provided with slide rails 4, and the slide rails 4 are engaged and slidably connected with the slider 5. One side of the slider 5 is connected to the slide frame 6, and the inner side of the slide frame 6 is provided with a limit plate 7, which is fixed on the chassis 1. A telescopic rod 8 is connected to one side of the chassis 1, and one end of the telescopic rod 8 is connected to a push plate 9, a connecting spring 10 is connected to the middle of the push plate 9, and one end of the connecting spring 10 is connected to a force-applying component 11;
[0030] The specific operation is as follows. When in use, first place the two ends of the optical fiber to be tested into the clamp seat 303, and then the telescopic rod 8 drives the pushing plate 9 to move on the chassis 1, and then the bottom shell 1101 can be driven to move through the connecting spring 10, so that the bottom shell 1101 drives the pushing block 1107 to drive the connecting rod 1108 to move through the clamping block 1106, and then drives the clamping block 304 to approach the clamping seat 303 through the clamping seat 1109, until the clamping block 304 is engaged with the clamping seat 303, the limiting plate 7 can limit the clamping seat 1109, so that it can only move toward the clamping seat 303 before the clamping block 304 is engaged with the clamping seat 303, to prevent it from lateral displacement, and after the clamping block 304 is engaged with the clamping seat 303, the limiting plate 7 no longer limits the moving direction of the clamping seat 1109, and at the same time, the clamping block 304 and The soft pad 307 on the inner side of the clamp seat 303 can firmly clamp the end of the optical fiber, and the flexible material of the soft pad 307 can prevent the end of the optical fiber from breaking when clamping.

After the restriction of the limit plate 7 is lost, the clamp seat 1109 can apply axial tensile force to the optical fiber through the clamp block 304 and the clamp seat 303 after being subjected to force, so as to perform a tensile test on it. Before the optical fiber is broken due to the force, the clamp seat 1109 continues to apply force to it through the clamp block 304 and the clamp seat 303 without displacement, and the connecting spring 10 is compressed as the push plate 9 moves. , and the bottom shell 1101 continuously applies force to the push block 1107 through the clamping block 1106, and the pressure sensor arranged in the push block 1107 can detect the magnitude of the applied force.

[0032] The specific operation is as follows. After the bottom shell 1101 passes through the pushing block 1107, the telescopic rod 8 continues to drive the pushing plate 9 to move, which can drive the toothed rod 13 and the rack 14 to move. When the rack 14 contacts the torsion wheel 311, the rack 14 can drive the turntable 309 to rotate.

During the detection process, the light board illuminates the optical fiber, and the high-definition probe 17 shoots the optical fiber to observe whether the optical fiber will break or have cracks inside during the detection.If the optical fiber is intact, it means the test has passed, otherwise it means the test has failed. In summary, after the tensile test is completed, the torsion and bending tests can be performed on the optical fiber without transferring it.
[0033] In summary, when using this optical fiber testing equipment with uniform force, first place the two ends of the optical fiber to be tested into the clamp seat 303, and then the telescopic rod 8 drives the pushing plate 9 to move on the chassis 1, and then the bottom shell 1101 can be driven to move through the connecting spring 10, so that the bottom shell 1101 drives the pushing block 1107 to drive the connecting rod 1108 to move through the clamping block 1106, and then drives the clamping block 304 to approach the clamping seat 303 through the clamping seat 1109, until the clamping block 304 is engaged with the clamping seat 303, and the limit plate 7 can limit the clamping seat 1109, so that it can only move toward the clamping seat 303 before the clamping block 304 is engaged with the clamping seat 303, to avoid lateral displacement, and after the clamping block 304 is engaged with the clamping seat 303, the limit plate 7 no longer limits the movement of the clamping seat 1109 In the same time, the clamp block 304 and the soft pad 307 inside the clamp seat 303 can firmly clamp the end of the optical fiber, and the flexible material of the soft pad 307 can prevent the end of the optical fiber from breaking when clamping. After the clamping is firm, the telescopic rod 8 drives the push plate 9 to continue to move, and the clamp seat 1109 can continue to be forced through the connecting spring 10, the bottom shell 1101, the push block 1107, and the connecting rod 1108. After the restriction of the limit plate 7 is lost, the clamp seat 1109 can apply axial tensile force to the optical fiber through the clamp block 304 and the clamp seat 303 after being stressed, so as to perform a tensile test on it. Before the optical fiber is broken by the force, the clamp seat 1109 continues to apply force to it through the clamp block 304 and the clamp seat 303 without displacement. The connecting spring 1 As the push plate 9 moves, it is compressed, and the bottom shell 1101 continuously applies force to the push block 1107 through the clamping block 1106, and the pressure sensor provided in the push block 1107 can detect the magnitude of the applied force. If the optical fiber is still not broken after reaching the preset value of the applied force, it means that the optical fiber has passed the tensile test. If the optical fiber breaks before reaching the preset value, it means that it has not passed the tensile test. At this time, the device can be restored to its original state to test the next optical fiber. When the clamping seat 1109 moves, it can drive the slide frame 6 to move synchronously, and the slider 5 can limit the slide frame 6 through the slide rail 4 to prevent the slide frame 6 from deflecting when moving. After the clamping block 304 is engaged with the clamping seat 303, the slider 5 moves to the end of the slide rail 4, and the slide frame 6 is restricted and cannot continue to move. The sliding frame 6 can move so that the card seat 1109 can be restricted. After the optical fiber passes the tensile test, the electromagnetic block 1104 is energized, and the card block 1106 can be sucked into the card cavity 1103 and the reset spring 1105 can be compressed, so that the bottom shell 1101 can no longer apply force to the push block 1107 through the card block 1106, thereby relieving the axial force of the optical fiber. At this time, the bottom shell 1101 can pass through the push block 1107 under the action of the connecting spring 10. After the bottom shell 1101 passes through the push block 1107, the telescopic rod 8 continues to drive the push plate 9 to move, which can drive the gear rod 13 and the rack 14 to move. When the rack 14 contacts the torsion wheel 311, the rack 14 can drive the turntable 309 to rotate, and when the clamping block 304 is engaged with the clamping seat 303,The engaging block 308 is also engaged with the turntable 309 through the engaging groove 310, so that when the turntable 309 drives the soft pad 307 on the inner side of the clamp seat 303 to move, the soft pad 307 on the inner side of the clamp block 304 can also be driven to move through the engaging groove 310 and the engaging block 308, so that the clamp block 304 and the soft pad 307 on the inner side of the clamp seat 303 move synchronously inside the clamp block 304 and the clamp seat 303 and drive the optical fiber end to rotate, and the racks 14 on both sides of the push plate 9 are distributed on its upper and lower sides, so that the racks 14 can drive the torsion wheels 311 on both sides to rotate in opposite directions, thereby performing an initial torsion test on the optical fiber. If the optical fiber passes the initial torsion test, the optical fiber can be restored after the rack 14 is separated from the torsion wheel 311, and the turntable 304 can be driven by the soft pad 307. 9 and the twisting wheel 311 are reset, and then the telescopic rod 8 continues to drive the pushing plate 9 to move, so that the gear rod 13 contacts the gear ring 302, and the gear rod 13 drives the base 301 to rotate in the slide groove 2 through the gear ring 302, so that the clamp seat 303 and the clamp block 304 can apply force to the optical fiber end to bend the optical fiber, so as to perform bending detection on it. When the optical fiber is bent, because its end is fixed between the clamp seat 303 and the clamp block 304, the optical fiber will drive the base 301 to slide in the slide groove 2 during the bending process, and drive the clamp seat 1109 to slide on the inner side of the slide frame 6. When the base 301 rotates, the clamp block 304 will also drive the arc block 312 to slide in the arc groove 1110, and the clamp seat 1109 can pass through the arc groove 1110 and the arc block 312 to slide. 12 limits the clamping block 304 to prevent the optical fiber from being damaged due to excessive bending angle. When the base 301 moves, the toothed ring 302 can drive the toothed rod 13 to move through. The card slot 12 can limit the toothed rod 13 to prevent the toothed rod 13 from being deflected when moving. If the optical fiber passes the bending detection, the telescopic rod 8 drives the push plate 9 to move back, and the toothed rod 13 and the rack 14 move synchronously with the push plate 9. When the toothed rod 13 moves back, it can drive the toothed ring 302 to reverse, so that the optical fiber can be restored. The magnetic adsorption between the toothed rod 13 and the toothed ring 302 can ensure the meshing connection between the toothed rod 13 and the toothed ring 302, so as to avoid the toothed rod 13 and the toothed ring 302 being separated during the bending and restoration process of the optical fiber, resulting in the inability to bend and restore the optical fiber. After the rack 14 contacts the twisting wheel 311 again, the twisting wheel 311 can be used to reversely twist the optical fiber for secondary twisting detection. During the movement of the cushion 307, the swivel 306 can limit the cushion 307 through the annular groove 305 to prevent the cushion 307 from deflecting during movement. During the detection process, the light board illuminates the optical fiber, and the high-definition probe 17 shoots the optical fiber to observe whether the optical fiber will break or have cracks inside during the detection. If the optical fiber is intact, it means that the detection has passed, otherwise it means that the detection has failed. After all the tests are completed, the electromagnetic block 1104 is powered off, and the card block 1106 can rebound and pop out of the card cavity 1103 under the action of the reset spring 1105. When the telescopic rod 8 drives the push plate 9 to reset,The bottom shell 1101 can move together with the push plate 9 through the connecting spring 10, and when the clamping block 1106 contacts the push block 1107, the clamping block 1106 drives the push block 1107 to move synchronously, so that the push block 1107 drives the clamping seat 1109 to move and reset through the connecting rod 1108, and drives the slide frame 6 to reset, so as to facilitate the next detection.
