[0049] like Figures 1 to 14 As shown, a coating device for improving the reflection efficiency of an optical fiber array includes a support base 1, an optical fiber fixing part 2 and a coating part 3. There is at least one optical fiber fixing part 2, which is connected to the support base 1. Each optical fiber fixing part 2 includes an optical fiber clamping part 21. There are two optical fiber clamping parts 21. The two optical fiber clamping parts 21 are rotatably connected to both sides of the support base 1. The two optical fiber clamping parts 21 are located at both ends of the optical fiber body and can drive the optical fiber body to rotate; the coating part 3 is slidably connected to the support base 1 and is located directly above the optical fiber body. It can move axially along the optical fiber body to coat the optical fiber body.

[0050] In the embodiment, the optical fiber fixing member 2 is connected to the support base 1 and symmetrically arranged on both sides of the optical fiber body to clamp and fix the optical fiber body. Therefore, the optical fiber body is stably fixed during rotation, effectively avoiding the sliding of the optical fiber body during rotation and ensuring that the coating member 3 uniformly coats the optical fiber body. The problem of poor coating effect caused by the sliding of the optical fiber during turning in the prior art is effectively solved.

[0051] In some embodiments, the optical fiber fixing member 2 includes optical fiber fixing bearings 22, two of which are fixedly connected to the support base 1 at the outer rings and fixedly connected to the optical fiber clamping members 21 at the inner rings.

[0052] In some embodiments, each of the optical fiber clamping members 21 includes an optical fiber clamping cylinder 211, three rod cylinders 212, an extension rod 213, and a clamping head 214. The optical fiber clamping cylinder 211 is connected to the inner ring of the optical fiber fixing bearing 22. The three rod cylinders 212 are arranged in a ring shape and connected to the outer side of the optical fiber clamping cylinder 211. The extension rod 213 is correspondingly arranged with the rod cylinder 212 and slidably connected to the optical fiber clamping cylinder 211. The clamping head 214 is correspondingly arranged with the extension rod 213 and connected to one end of the extension rod 213 close to the optical fiber body. The clamping head 214 abuts against the optical fiber body.

[0053] In some embodiments, each of the optical fiber clamping members 21 further includes a resilient member 215, one end of which abuts against the extension rod 213 and the other end of which abuts against the rod cylinder 212. When the optical fiber body abuts against the clamping head 214, the resilient member 215 pushes the extension rod 213 to make the clamping head 214 tightly clamp the optical fiber body.

[0054] In the embodiment, the outer ring of the optical fiber fixing bearing 22 is fixedly connected to the support base 1, and the inner ring of the optical fiber fixing bearing 22 is connected to the optical fiber clamping cylinder 211. Thus, the optical fiber clamping cylinder 211 can rotate on the support base 1. After the optical fiber body is inserted into the optical fiber clamping cylinder 211 at both ends, the resilient member 215 pushes the extension rod 213 to make the clamping head 214 tightly clamp the optical fiber body. Since the clamping head 214 is provided with three clamping heads 214 arranged at 0°, 120°, and 240° positions in the radial direction of the optical fiber body, the optical fiber body can be stably clamped during rotation. It should be noted that the number of clamping heads 214 can be adjusted according to actual conditions, such as two or more than three, as long as the optical fiber body can be clamped. In addition, if the optical fiber body is not clamped by the clamping head 214, the optical fiber body can be clamped by the clamping head 214. Figure 13As shown, a tension knob is arranged at the upper end of the elastic member 215, and the tension knob is threadedly connected with the rod barrel 212, so as to adjust the clamping force of the clamping head 214 in use.

[0055] In some embodiments, the clamping head 214 is made of elastic copper sheet.

[0056] In the embodiment, the clamping head 214 is made of elastic copper sheet, so as to ensure that the fiber body is clamped without damage.

[0057] In some embodiments, one of the two fiber clamping members 21 is a driving clamping member, and the other is a driven clamping member, and the device further comprises a clamping driving member 23, which comprises a first gear 231, a second gear 232 and a clamping driving motor 233, the first gear 231 is connected to one end of the fiber clamping barrel 211 of the driving clamping member; the second gear 232 is engaged with the first gear 231; the clamping driving motor 233 is provided with a fixed end and a rotating end, the fixed end of the clamping driving motor 233 is connected with the support base 1, and the rotating end of the clamping driving motor 233 is connected with the second gear 232.

[0058] In the embodiment, the driving clamping member is the driving end of the fiber clamping member 21, that is, the clamping driving motor 233 drives the second gear 232 to rotate, the second gear 232 drives the first gear 231 to rotate, and the first gear 231 drives the fiber clamping barrel 211 of the driving clamping member to rotate. The clamping driving motor 233 is a servo motor.

[0059] In some embodiments, the clamping driving member 23 further comprises a synchronous driving member 234, which comprises a third gear 2341, a transmission rod 2342, a fourth gear 2343, a fifth gear 2344 and a sixth gear 2345, the third gear 2341 is engaged with the second gear 232; the transmission rod 2342 is connected with the third gear 2341; the fourth gear 2343 is connected with the transmission rod 2342; the fifth gear 2344 is rotatably connected with the support base 1, and the fifth gear 2344 is engaged with the fourth gear 2343; the sixth gear 2345 is connected to one end of the fiber clamping barrel 211 of the driven clamping member, and the sixth gear 2345 is engaged with the fifth gear 2344.

[0060] In the embodiment, the two ends of the optical fiber body should keep the same motion state. Therefore, the second gear 232 drives the third gear 2341 to rotate. The third gear 2341 drives the transmission rod 2342 to rotate. The transmission rod 2342 drives the fourth gear 2343 to rotate. The fourth gear 2343 drives the fifth gear 2344 to rotate. The fifth gear 2344 drives the sixth gear 2345 to rotate. The sixth gear 2345 is fixed at one end of the optical fiber clamping cylinder 211 of the driven clamping member. Thus, it is ensured that the optical fiber clamping cylinder 211 of the driving clamping member keeps the same motion state with the optical fiber clamping cylinder 211 of the driven clamping member.

[0061] In some embodiments, the support base 1 is connected with guide rails 11 on both sides above the support base 1. The coating member 3 comprises a linear motor 31, a coating support 32, a coating moving member 33, a lifting cylinder 34, a coating part 35, a coating clamp 36 and a coating needle 37. The linear motor 31 is arranged corresponding to the guide rails 11 and is in sliding connection with the guide rails 11. The coating support 32 is connected to the linear motor 31. The coating moving member 33 is connected to the coating support 32. The lifting cylinder 34 is provided with a fixed end and an extension end.

[0062] In the embodiment, the linear motor 31 drives the coating support 32 to move on the guide rails 11. Since the optical fiber bodies are arranged in an array from one end of the support base 1 to the other end, the coating member 3 can coat each optical fiber body under the driving of the linear motor 31. When the lifting cylinder 34 extends, the coating needle 37 can be driven to approach the optical fiber body. When the lifting cylinder 34 retracts, the coating needle 37 can be driven to move away from the optical fiber body, so as to avoid interference between the coating needle 37 and the optical fiber body. In addition, the linear motor 31 adopts a FUYU30T type screw sliding table linear motor.

[0063] In some embodiments, the support base 1 is provided with guide grooves 12. The coating moving member 33 comprises a rotating screw 331, a sliding block 332, a guide piece 333 and a moving drive motor 334. The rotating screw 331 is rotatably connected to both ends of the coating support 32. The sliding block 332 is in threaded connection with the rotating screw 331. The guide piece 333 is connected to the upper end of the sliding block 332 and is in sliding connection with the guide grooves 12, so as to limit the sliding block 332. The moving drive motor 334 is provided with a fixed end and a rotating end. The fixed end of the moving drive motor 334 is connected to the coating support 32. The rotating end of the moving drive motor 334 is connected to the rotating screw 331.

[0064] In the embodiment, the moving driving motor 334 drives the rotating screw 331 to rotate, and the rotating screw 331 drives the sliding block 332 to move. Meanwhile, the guide vane 333 slides in the guide groove 12, so as to ensure the stable movement of the sliding block 332. In addition, the moving driving motor 334 is a servo motor.

[0065] In some embodiments, the positioning member 4 is further included, which comprises a position sensor emitting end 41 and a position sensor sensing end 42. The position sensor emitting end 41 is connected to the linear motor 31, and the position sensor sensing end 42 is connected to the support base 1 and is located in the same plane with the optical fiber body.

[0066] In the embodiment, when the position sensor emitting end 41 moves to the corresponding position sensor sensing end 42, the coating member 3 performs the coating operation on the corresponding optical fiber body. In addition, the position sensor emitting end 41 and the position sensor sensing end 42 are NPN normally open three-wire direct current sensors.
