Description

Technical Field

[0001] The utility model belongs to the field of lasers, and specifically relates to a coiling device for a laser fiber optic cable. Background Art

[0002] A laser refers to a laser using rare earth element-doped glass optical fiber as a gain medium. The fiber laser has a very wide range of applications, including laser fiber communication, laser space long-distance communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing roller making, metal and non-metal drilling / cutting / welding (brazing, quenching, cladding, and deep welding), military national defense security, medical device and equipment, large infrastructure construction, and as a pump source for other lasers.

[0003] When in use, a laser is interconnected with an optical fiber. The optical fiber is flexible. After being bent to a certain degree, although the optical fiber can conduct light, it will change the light transmission path, converting from a transmission mode to a radiation mode, causing a part of the light energy to penetrate into the cladding or pass through the cladding to become a radiation mode and leak outwards, thus generating losses.

[0004] Generally, before and after use, the optical fiber of the laser is mostly coiled into a circular shape and then tied together. However, if the diameter of the coiled circle is too large, it will cause too large a curvature and the optical signal cannot be refracted to reach the opposite end. Moreover, there is also a risk of folding when the tied optical fiber is directly placed on the laser.

[0005] In summary, the utility model provides a coiling device for a laser fiber optic cable to solve the above problems. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A coiling device for a laser fiber optic cable includes a main body, which includes a laser, an optical fiber cable, and a laser isolator. The two ends of the optical fiber cable are respectively connected to the interfaces of the laser and the laser isolator. A tightening mechanism is provided on the top of the laser. The tightening mechanism includes a coiling box. The bottom of the coiling box is fixedly connected to the top of the laser. A slideway is opened at the bottom of the inner cavity of the coiling box. A servo motor is fixedly connected to the center of the inner cavity of the slideway. Both output ends of the servo motor are drivingly connected with threaded rods. Both ends of the threaded rods are movably connected to the inner wall of the slideway through bearings. A slider is threadedly connected to the surface of the threaded rod. The slider is slidably connected to the inner cavity of the slideway. A semi-circular plate is fixedly connected to the top of the slider. The optical fiber cable is cross-wound around the surfaces of the two semi-circular plates.

[0008] Furthermore, in the utility model, holes for the optical fiber cable to pass through are opened on both sides of the coiling box.

[0009] Furthermore, in the present utility model, convex edges are provided at both the top and bottom of the semi-circular plate, and a guiding ring is fixedly connected to one side of the semi-circular plate, and the optical fiber line passes through its inner cavity.

[0010] Furthermore, in the present utility model, limiting blocks are provided on both sides of the slider, and limiting grooves are respectively formed on both sides of the inner cavity of the slideway. One end of the limiting block away from the slider extends into the inner cavity of the limiting groove and is slidably connected thereto.

[0011] Furthermore, in the present utility model, a transparent cover plate is connected to the top of the winding box by bolts.

[0012] Beneficial effects: The present utility model has the following beneficial effects:

[0013] By providing a tightening mechanism in the present utility model for winding and protecting the optical fiber line, the output end of the servo motor drives the threaded rod to rotate, and the slider will move accordingly, so that the two semi-circular plates make an opening movement. The optical fiber line is cross-wound around the surfaces of the two semi-circular plates. Therefore, when the two semi-circular plates open, they will expand and support the optical fiber line, so as to pull both ends of the optical fiber line towards the inner cavity of the winding box.

[0021] To better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows. In the present disclosure, aspects of the present utility model are described with reference to the drawings, and many illustrative embodiments are shown in the drawings. The embodiments of the present disclosure do not necessarily define all aspects of the present utility model. It should be understood that the various concepts and embodiments introduced above, as well as those concepts and embodiments described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the present utility model are not limited to any implementation manner. In addition, some aspects disclosed in the present utility model can be used alone, or in any suitable combination with other aspects disclosed in the present utility model.

[0022] Embodiment 1

[0023] As Figures 1-5 shown, this is the first embodiment of the present utility model. This embodiment provides a coiling device for a laser fiber optic cable, which includes a main body 1. The main body 1 includes a laser 101, a fiber optic cable 102, and a laser isolator 103. Both ends of the fiber optic cable 102 are connected to the interfaces of the laser 101 and the laser isolator 103 respectively. A tightening mechanism 2 is provided on the top of the laser 101. The tightening mechanism 2 includes a coiling box 201. The bottom of the coiling box 201 is fixedly connected to the top of the laser 101. A slideway 202 is opened at the bottom of the inner cavity of the coiling box 201. A servo motor 203 is fixedly connected to the center of the inner cavity of the slideway 202. Both output ends of the servo motor 203 are drivingly connected with threaded rods 204. Both ends of the threaded rods 204 are movably connected to the inner wall of the slideway 202 through bearings. A slider 205 is threadedly connected to the surface of the threaded rods 204. The slider 205 is slidably connected to the inner cavity of the slideway 202. A semi-circular plate 206 is fixedly connected to the top of the slider 205. The fiber optic cable 102 is cross-wound around the surfaces of the two semi-circular plates 206.

[0024] As Figures 1-5 shown, by setting the tightening mechanism 2, it is used to coil and protect the fiber optic cable 102. Among them, the output end of the servo motor 203 drives the threaded rod 204 to rotate, and the slider 205 will move accordingly. Thus, the two semi-circular plates 206 make an opening movement. The fiber optic cable 102 is cross-wound around the surfaces of the two semi-circular plates 206. Therefore, when the two semi-circular plates 206 open, they will form an expansion support for the fiber optic cable 102. Thus, both ends of the fiber optic cable 102 are pulled towards the inner cavity of the coiling box 201.

[0025] Embodiment 2

[0026] Referring to Figures 1-5 , this is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0027] In this embodiment, holes for the fiber optic cable 102 to pass through are opened on both sides of the coiling box 201.

[0028] Both the top and bottom of the semi-circular plate 206 are provided with convex edges. One side of the semi-circular plate 206 is fixedly connected with a guide ring 206-1, and the optical fiber line 102 passes through its inner cavity.

[0029] Limit blocks are provided on both sides of the slider 205, and limit grooves are opened on both sides of the inner cavity of the slideway 202. One end of the limit block away from the slider 205 extends into the inner cavity of the limit groove and is slidably connected thereto.

[0030] The top of the winding box 201 is bolted with a transparent cover plate for observing the optical fiber line 102 and facilitating the maintenance and replacement of the optical fiber line 102.

[0031] As Figures 1-5 shown, after the optical fiber line 102 is connected to the laser 101, the other end enters the inner cavity of the winding box 201 through a hole, crosses and winds around the surfaces of the two semi-circular plates 206, and then passes through another hole and is connected to the laser isolator 103. The guide ring 206-1 provided on the semi-circular plate 206 can prevent the optical fiber line 102 from slipping off its surface during the opening and closing of the semi-circular plate 206. The limit groove and the limit block are used to limit the movement of the semi-circular plate 206.

[0032] During use, after the optical fiber line 102 is connected to the laser 101, the other end enters the inner cavity of the winding box 201 through a hole. Then the optical fiber line 102 passes through the guide rings 206-1 on the left and right in sequence, crosses and winds around the surfaces of the two semi-circular plates 206, and then passes through another hole and is connected to the laser isolator 103. When it is necessary to tighten the optical fiber line 102, the output end of the servo motor 203 drives the threaded rod 204 to rotate, and the slider 205 will move accordingly. Thus, the two semi-circular plates 206 move in an opening state. The optical fiber line 102 is cross-wound around the surfaces of the two semi-circular plates 206. Therefore, when the two semi-circular plates 206 open, they will expand and support the optical fiber line 102. Therefore, the two ends of the optical fiber line 102 are pulled towards the inner cavity of the winding box 201 to tighten, realizing the winding of the optical fiber line 102. On the contrary, when the output shaft of the servo motor 203 rotates in the reverse direction and the semi-circular plate 206 moves in a closing state while pulling the optical fiber line 102, the extension of the optical fiber line 102 can be realized.
