[0050] Example 1

[0051] like Figures 1 to 2 As shown, it is the rotating clamp 100 for optical fiber cables according to the present invention.

[0052] like Figures 1 to 2 As shown, the optical fiber rotary clamp 100 includes a fixed base 10, a wire-carrying mechanism 20, and a driving mechanism 30. The fixed base 10 has a marking position 11. Multiple wire-carrying mechanisms 20 are arranged opposite each other on the marking position 11. Each wire-carrying mechanism 20 includes a wire-carrying roller 21 and a wire-pressing component 22. The wire-carrying roller 21 is rotatably connected to the fixed base 10 and has a notch 211 and a wire-placement groove 212 communicating with the notch 211. The wire-placement groove 212 is coaxially arranged with the rotation axis of the wire-carrying roller 21. The wire-pressing component 22 is detachably connected to the wire-carrying roller 21 and cooperates with the wire-carrying roller 21 to press the optical fiber wire in the wire-placement groove 212. The driving mechanism 30 drives the wire-carrying rollers of each wire-carrying mechanism 20. The optical fiber is rotated synchronously in the marking position 11. Each of the wire-carrying mechanisms 20 includes a wire-carrying roller 21 and a wire-pressing component 22. The wire-carrying roller 21 has a notch 211 and a wire-placement groove 212 that connects to the notch 211, and is rotatably connected to the fixed base 10. The wire-pressing component 22 is detachably connected to the wire-carrying roller 21 and cooperates with the wire-carrying roller 21 to press the optical fiber in the wire-placement groove 212. Multiple wire-carrying mechanisms 20 are arranged opposite each other on opposite sides of the marking position 11. The wire-carrying roller 21 of each wire-carrying mechanism 20 is driven to rotate synchronously by the driving mechanism 30. This facilitates the placement of the optical fiber in the wire-placement groove 212 through the notch 211 and fixation by the wire-pressing component 22. This can effectively reduce the installation time of the optical fiber and improve the processing efficiency of optical fiber rotation marking.

[0053] The following text, combined with Figures 1 to 7 The rotating clamp 100 for the optical fiber cable described above will be further explained.

[0054] like Figure 3As shown, the carrier roller 21 comprises a roller body 213 and a transmission wheel 214, the roller body 213 is detachably connected with the wire pressing member 22, and the transmission wheel 214 is in transmission connection with the driving mechanism 30. Through the transmission wheel 214 in transmission connection with the driving mechanism 30, the power of the driving mechanism 30 can be stably transmitted to the roller body 213, so that the roller body 213 can accurately rotate at a preset speed, and the stability of the marking process is ensured.

[0055] In order to improve the rotation accuracy of the optical fiber wire, in the embodiment, as shown in the figure, Figure 3 the transmission wheel 214 is a gear and is engaged with the driving mechanism 30. The gear is used as the transmission wheel 214, which is beneficial to effectively improve the synchronous rotation accuracy of the carrier roller 21 on both sides of the marking position 11, so as to improve the rotation accuracy of the optical fiber wire.

[0056] Further, in order to improve the installation accuracy of the optical fiber wire, as shown in the figure, Figures 4 to 5 the carrier roller 21 further comprises a non-slip pad 215, the non-slip pad 215 is connected with the roller body 213 and is attached with the wire pressing member 22. The roller body 213 is provided with a receiving groove 216 for accommodating the non-slip pad 215. The non-slip pad 215 increases the friction between the wire pressing member 22 and the carrier roller 21, which can more effectively prevent the displacement of the optical fiber wire during the marking process, so as to improve the marking accuracy. In addition, the arrangement of the receiving groove 216 ensures the accurate installation position of the non-slip pad 215, thereby improving the installation accuracy of the optical fiber wire.

[0057] In order to further improve the installation and dismounting efficiency of the optical fiber wire, please refer to Figure 5 the figure, Figure 6 the wire pressing member 22 comprises a pressing plate 221, a first magnetic member 222 and a second magnetic member 223. The pressing plate 221 is connected with the first magnetic member 222, and the first magnetic member 222 is magnetically attracted to the second magnetic member 223. The second magnetic member 223 is connected with the carrier roller 21. The first magnetic member 222 and the second magnetic member 223 are both magnets, or one of the first magnetic member 222 and the second magnetic member 223 is a magnet and the other is a metal. The first magnetic member 222 and the second magnetic member 223 are magnetically attracted to each other to quickly and easily connect the pressing plate 221 and the carrier roller 21, thereby further improving the installation and dismounting efficiency of the optical fiber wire.

[0058] In order to improve the fixing stability of the clamped optical fiber wire during movement, please refer to Figure 5 the figure, Figure 6The pressing piece 22 further comprises a plug rod 224 connected with the pressing plate 221, the carrier roller 21 is provided with a plug hole 217 matched with the plug rod 224, the matching of the plug rod 224 and the plug hole 217 further improves the stability of the connection between the pressing plate 221 and the carrier roller 21, prevents the pressing plate 221 from shaking or shifting relative to the carrier roller 21 during the rotation of the carrier roller 21, thereby ensuring the fixing effect of the optical fiber cable and improving the fixing stability of the clamped optical fiber cable during the movement.

[0059] Further, in order to improve the fixing effect of the pressing piece 22, as shown in Figure 6 the pressing piece 22 further comprises a flexible pad 225 connected with the side of the pressing plate 221 close to the carrier roller 21 and adhered to the carrier roller 21, the pressing plate 221 is provided with a mounting groove 226 for mounting the flexible pad 225, the flexible pad 225 avoids the hard contact between the pressing plate 221 and the optical fiber cable, and the contact between the flexible pad 225 and the optical fiber cable can not only avoid the bruising of the optical fiber cable, but also can wrap the optical fiber cable to improve the contact area and pressure of the flexible pad 225 on the optical fiber cable, thereby increasing the friction between the pressing piece 22 and the optical fiber cable and improving the fixing effect of the pressing piece 22.

[0060] Further, in order to improve the fixing effect of the pressing piece 22, as shown in Figure 6 the pressing piece 22 further comprises a handle 227 connected with the side of the pressing plate 221 away from the carrier roller 21, the handle 227 facilitates the operator to hold, making the disassembly and installation of the pressing plate 221 more convenient and labor-saving, thereby improving the disassembly and installation efficiency of the pressing piece 22.

[0061] In order to improve the marking quality of the optical fiber cable, as shown in Figure 7 the driving mechanism 30 comprises a driving assembly 31 in driving connection with each carrier roller 21 to drive the rotation of each carrier roller 21, wherein the driving assembly 31 comprises two synchronous belts 311, a transmission member 312 and a rotary driving member 313, each synchronous belt 311 is in driving connection with each carrier roller 21 arranged on the opposite side of the marking position 11, the transmission member 312 is in driving connection with each synchronous belt 311, and the rotary driving member 313 drives each synchronous belt 311 to drive each carrier roller 21 to rotate through the transmission member 312, wherein the synchronous belt 311 is engaged with the carrier roller 21, the synchronous rotation of each carrier roller 21 is realized through the transmission of the synchronous belt 311, the transmission is stable, the rotation speed of each carrier roller 21 is consistent, thereby ensuring the uniform rotation of the optical fiber cable during the marking process, and the marking quality of the optical fiber cable is improved.

[0062] In order to improve the marking precision, as shown in Figure 7As shown, the drive assembly 31 also includes a support block 314. The support block 314 is connected to the fixed base 10 and contacts the side of the synchronous belt 311 away from the wire roller 21. The support block 314 supports the synchronous belt 311, preventing the synchronous belt 311 from becoming loose or shaking during transmission, ensuring the stability and accuracy of transmission, and thus achieving the purpose of improving marking accuracy.

[0063] like Figure 2 As shown, in this embodiment, the rotating clamp 100 for optical fiber is used as follows: the optical fiber is controlled to be placed in the placement groove 212 through the notch 211 of the wire carrier roller 21. The handle 227 of the wire pressing member 22 is held, so that the insertion rod 224 of the wire pressing member 22 is inserted into the insertion hole 217 of the wire carrier roller 21 until the first magnetic suction member 222 and the second magnetic suction member 223 are attracted to each other. Using the attraction of the first magnetic suction member 222 and the second magnetic suction member 223, the optical fiber is loaded onto the wire carrier mechanism 20 through the cooperation of the flexible pad 225 of the wire pressing member 22 and the anti-slip pad 215 of the wire carrier roller 21. The optical fiber is installed by controlling the optical fiber to be loaded onto the wire carrier mechanism 20 on the opposite side of the marking position 11. The drive component 31 is started, and the drive component 31 drives the transmission wheel 214 of each wire carrier roller 21 to rotate synchronously, thereby controlling the rotation of the optical fiber.

[0064] Example 2

[0065] The difference from Embodiment 1 is that, in order to improve the loading or unloading efficiency of optical fiber cables, please combine... Figure 2 refer to Figures 8 to 9 The drive mechanism 30 also includes a limiting component 32, which is used to contact each wire carrier roller 21 so that the notch 211 faces the side of the wire carrier roller 21 away from the fixed base 10. The setting of the limiting component 32 can ensure that the notch 211 always faces the side of the wire carrier roller 21 away from the fixed base 10 when the optical fiber is installed and removed, which makes it easier for the operator to put the optical fiber into or take it out of the wire placement groove 212, thereby improving the loading or unloading efficiency of the optical fiber.

[0066] Specifically, such as Figure 9As shown, the limiting assembly 32 comprises limiting blocks 321 and limiting driving members 322. The limiting blocks 321 have avoiding positions 323 and limiting surfaces 324. The limiting driving members 322 drive the avoiding positions 323 or the limiting surfaces 324 of the limiting blocks 321 to move to the wire carrier roller 21. When the avoiding positions 323 move to the wire carrier roller 21, the wire carrier roller 21 is free to rotate. When the limiting surfaces 324 move to the wire carrier roller 21, the wire carrier roller 21 is in contact with the limiting surfaces 324. The wire carrier roller 21 is provided with a positioning surface 218 which is in contact with the limiting surfaces 324 at one end away from the gap 211. The cooperation between the limiting blocks 321 and the positioning surface 218 can accurately control the rotating angle of the wire carrier roller 21, ensure the accurate position of the gap 211, facilitate the installation and dismounting of the optical fiber wire, and also ensure the accuracy of the marking position 11.

[0067] Further, as shown in Figure 9 , the number of limiting blocks 321 is two groups. Each limiting block 321 is arranged at the corresponding wire carrier roller 21 on the opposite side of the marking position 11. The limiting assembly 32 further comprises a switching block connecting the limiting blocks 321. The switching block is connected with the limiting driving member 322. The limiting driving member 322 is a pneumatic cylinder. The two groups of limiting blocks 321 are arranged at the corresponding wire carrier rollers 21 on the opposite sides of the marking position 11. The two ends of the optical fiber wire at the marking position 11 can be effectively limited at the same time, so as to ensure the stability of the optical fiber wire during rotation.

[0068] In order to improve the displacement accuracy of the limiting block 321, as shown in Figure 9 , the fixed seat 10 is provided with a guide groove 12. The limiting block 321 is slidingly arranged in the guide groove 12. The guide groove 12 guides the movement of the limiting block 321, so as to ensure that the limiting block 321 can move along the predetermined track, and improve the displacement accuracy of the limiting block 321.

[0069] Further, please refer to Figure 7 for reference Figure 2 . The driving assembly 31 further comprises a sensing sheet 325 and a sensor 326. The sensing sheet 325 is connected with the transmission member 312. The sensor 326 is installed on the fixed seat 10 and is signal connected with the rotating driving member 313. When the sensor 326 senses the sensing sheet 325, the positioning surface 218 of the wire carrier roller 21 faces the limiting block 321.

[0075] Embodiment Four

[0076] Different from the first embodiment, in order to make the optical fiber line rotate in a tensioned state and improve the position accuracy of the optical fiber line during rotation, in the present embodiment, as shown in Figures 11 to 12 The fixed base 10 comprises a base body 13 and a guide assembly 14. The base body 13 is provided with a wire port 131. The guide assembly 14 is inserted with the base body 13 and surrounds the wire port 131 to form a guide space 15. The guide assembly 14 is provided with a limiting port 141 which gradually expands towards the side close to the base body 13. The gradually expanding limiting port 141 towards the side close to the base body 13 facilitates the entry of the optical fiber line into the limiting port 141. The guide assembly 14 and the wire port 131 of the base body 13 surround the guide space 15, which can guide the optical fiber line and enable the optical fiber line to rotate under the limitation of the guide space 15, achieving the purpose of improving the position accuracy of the optical fiber line during rotation.

[0077] In order to improve the assembly accuracy of the guide assembly 14, as shown in Figure 12As shown, the guide assembly 14 includes a pressure cap 142, a limiting rod 143, an elastic element 144, and a positioning rod 145. The pressure cap 142 is slidably connected to the limiting rod 143. The limiting rod 143 is provided with a limiting port 141. The elastic element 144 is used to provide elastic force for the limiting rod 143 to abut against the seat 13. The positioning rod 145 is connected to the pressure cap 142. The seat 13 is provided with a positioning hole that cooperates with the positioning rod 145. The elastic element 144 is a spring. The elastic force provided by the elastic element 144 makes the limiting rod 143 and the seat 13 tightly abut against each other. This can effectively ensure the positional accuracy of the guide space 15 and prevent the optical fiber from shifting during the guidance process. It can also avoid hard contact between the guide assembly 14 and the optical fiber, which would cause damage to the optical fiber. At the same time, the cooperation between the positioning rod 145 and the positioning hole ensures the accuracy of the connection between the guide assembly 14 and the seat 13, thereby improving the assembly accuracy of the guide assembly 14.

[0078] To improve the limiting accuracy of the limiting rod 143, such as Figure 12 As shown, the guide assembly 14 also includes a guide rod 146 connected to the limiting rod 143. The cover 142 is provided with a slide groove 147 for the guide rod 146 to slide. By guiding the guide rod 146 through the slide groove 147, the guide rod 146 can be effectively prevented from rotating relative to the optical fiber, so as to improve the limiting accuracy of the limiting rod 143.

[0079] To improve the convenience and reliability of fiber optic cable positioning, please combine... Figure 11 refer to Figure 12 The guide assembly 14 also includes a third magnetic 148 and a fourth magnetic 149. The third magnetic 148 is connected to the positioning rod 145 and is correspondingly attracted to the fourth magnetic 149. The fourth magnetic 149 is connected to the base 13. Both the third magnetic 148 and the fourth magnetic 149 are magnets, or one of the third magnetic 148 and the fourth magnetic 149 is a magnet and the other is metal. The magnetic attraction between the third magnetic 148 and the fourth magnetic 149 further enhances the connection stability and convenience between the guide assembly 14 and the base 13, and can effectively prevent the guide assembly 14 from loosening during use, thereby improving the convenience and reliability of the fiber optic cable's positioning.

[0080] In this embodiment, when the guide assembly 14 of the rotating clamp 100 for optical fiber is in use: the positioning rod 145 of the guide assembly 14 is inserted into the positioning hole of the base 13 until the third magnetic suction member 148 and the fourth magnetic suction member 149 are attracted to each other. At the same time, the limiting rod 143 is inserted into the wire port 131 of the base 13. The limiting port 141 of the limiting rod 143 is used to limit the optical fiber, so as to improve the positional accuracy of the optical fiber.
