Description

Technical Field

[0001] This utility model relates to the field of optical fiber sheathing technology, and in particular to an optical fiber sheathing crack detection device. Background Technology

[0002] Fiber optic sleeve crack detection equipment is an important tool for detecting cracks or damage in fiber optic sleeves. Fiber optic sleeves are tubular materials used to protect optical fibers and play a crucial role in fields such as fiber optic communication, fiber optic sensing, and fiber optic transmission. Fiber optic sleeves can be divided into various types, such as stainless steel loose sleeves, polyimide sleeves, polyurethane sleeves, fluoroplastic sleeves, as well as three-proof corrugated tubes and plastic corrugated tubes.

[0003] To ensure communication quality and prevent safety hazards, fiber optic sleeves must be inspected using crack detection equipment before leaving the factory. Crack detection allows for the timely discovery and repair of damaged fiber optic sleeves, ensuring stable optical signal transmission. Currently, some equipment inspects fiber optic sleeves by moving them from a shelf downwards, using a combination of visual imaging and inspection equipment to continuously monitor their surface. In other cases, the fiber optic sleeve is directly transported downwards from one end of the shelf to the inspection area. Factors such as excessively fast or slow transport speeds and vibrations can cause the fiber optic sleeve to become unstable during movement, easily leading to deviation. This deviation can prevent the fiber optic sleeve from accurately entering the inspection area, thus affecting the imaging effect and the accuracy of crack identification by the inspection equipment. Therefore, a fiber optic sleeve crack detection device is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a fiber optic sleeve crack detection device to address the aforementioned technical problems.

[0005] In order to solve the above-mentioned technical problems, the present invention solves the problems mentioned in the background art through the following technical solution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fiber optic sleeve crack detection device, comprising:

[0008] The equipment box has a stand fixedly connected to its top, a detection seat is installed in the middle of the top of the equipment box, and a visual imaging device is installed on one side of the top of the equipment box. The detection seat and the visual imaging device are used to detect cracks in the sleeve.

[0009] The sleeve guide and adjusting component are located on one side of the upright. The sleeve guide includes a mounting plate. A front frame is fixedly connected to the front of the mounting plate. Multiple limiting rollers are installed on the front of the front frame. A sleeve buffer is provided on the top of the upright.

[0010] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, two connecting frames are fixedly connected to the bottom of one side wall of the mounting plate, and the two connecting frames are fixedly connected to the surface of the upright.

[0011] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, the adjusting component includes a movable plate placed between the stand and the mounting plate, and multiple pairs of hollow plates are fixedly connected through the surface of the mounting plate, and multiple pairs of through plates are fixedly connected to the front side of the movable plate.

[0012] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, multiple through plates movably penetrate the inner cavity of multiple hollow plates, and a limit roller is installed between two adjacent through plates.

[0013] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, a threaded rod is threaded through the middle of the surface of the moving plate, and one end of the threaded rod is rotatably connected to the surface of the mounting plate.

[0014] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, the other end of the threaded rod movably penetrates the surface of the stand and is fixedly connected to a knob.

[0015] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, the sleeve buffer includes a rotating plate rotatably connected to the top of the support frame, and a guide wheel is installed at the top of the rotating plate.

[0016] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, a fixing plate is fixedly connected to one side of the rotating plate surface, and the fixing plate is L-shaped.

[0017] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, a spring sheet is fixedly connected to one side of the top of the support frame.

[0018] In a preferred embodiment of the fiber optic sleeve crack detection device provided by this utility model, one end of the spring sheet is fixedly connected to one end of the fixing plate.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This utility model provides a fiber optic sleeve crack detection device. When one end of the fiber optic sleeve is conveyed downward through the sleeve buffer, it passes between multiple limiting rollers (second and first). The rotation of the threaded rod causes the moving plate, under the action of the through plate and the hollow plate, to move the multiple limiting rollers (second) to one side, cooperating with the limiting roller (first) to form a confined space. This ensures that the outer wall of the fiber optic sleeve is tightly fitted to the limiting rollers (first and second) during the conveying process, thus constraining it and achieving a limiting operation on the fiber optic sleeve. This prevents it from deviating when conveying to the detection seat, ensuring that it can accurately enter the detection seat and undergo crack detection. This will help improve the accuracy and stability of the detection, and guarantee the quality and safety of the fiber optic sleeve.

[0021] This utility model provides a fiber optic sleeve crack detection device. When the fiber optic sleeve moves downwards on the guide wheel, the rotating plate is rotatable and cooperates with the spring plate to move the part of the guide wheel supporting the fiber optic sleeve to the highest point, keeping the end of the fiber optic sleeve being detected taut. This helps to ensure the accuracy and stability of the detection. The taut fiber optic sleeve makes it easier for the crack detection sensor to capture any tiny cracks or defects, thereby improving the reliability of the detection. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example

[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A fiber optic sleeve crack detection device includes a device box 1, which serves as the main support structure for the entire detection device. The device box 1 has a structure for pulling in the fiber optic sleeve. After the fiber optic sleeve passes through the detection seat 3 into the device, the device box 1 performs operations such as processing and removing the cracked parts of the fiber optic sleeve. These are existing technologies and will not be described in detail here. A stand 2 is fixedly connected to the top of the device box 1, and a detection seat 3 is installed in the middle of the top of the device box 1. When the fiber optic sleeve passes through the detection seat 3 and enters the device box 1, the surface of the fiber optic sleeve is detected. A visual imaging device 4 is installed on one side of the top of the device box 1 to capture crack information on the surface of the fiber optic sleeve by taking pictures or videos. The detection seat 3 and the visual imaging device 4 are used to detect cracks in the sleeve.

[0033] The sleeve guide 5 and the adjusting component 6 are located on one side of the support frame 2. The sleeve guide 5 includes a mounting plate 51. A front frame 53 is fixedly connected to the front of the mounting plate 51. Multiple limiting rollers 54 are installed on the front of the front frame 53 to limit the movement direction of the optical fiber sleeve and prevent it from deviating from the predetermined path. A sleeve buffer 7 is provided on the top of the support frame 2.

[0034] In the embodiments of this application, two connecting frames 52 are fixedly connected to the bottom of one side wall of the mounting plate 51. The two connecting frames 52 are fixedly connected to the surface of the upright frame 2. The adjusting member 6 includes a movable plate 61 placed between the upright frame 2 and the mounting plate 51. It moves under the guidance of hollow plates 62 and through plates 63 by the rotation of the threaded rod 65. Multiple pairs of hollow plates 62 are fixedly connected to the surface of the mounting plate 51. Multiple pairs of through plates 63 are fixedly connected to the front of the movable plate 61. Multiple through plates 63 respectively move through the inner cavity of multiple hollow plates 62. Limiting roller 64 is installed between two adjacent through plates 63. It cooperates with limiting roller 54 to further limit the movement direction of the optical fiber sleeve and ensure that it accurately enters the detection area. A threaded rod 65 is threaded through the middle of the surface of the movable plate 61. One end of the threaded rod 65 is rotatably connected to the surface of the mounting plate 51. The other end of the threaded rod 65 moves through the surface of the upright frame 2 and is fixedly connected to a knob 66.

[0035] In the embodiments of this application, the sleeve buffer 7 includes a rotating plate 71 rotatably connected to the top of the support 2. A guide wheel 72 is installed at the top of the rotating plate 71 to support and guide the optical fiber sleeve into the detection area. A fixing plate 73 is fixedly connected to one side of the surface of the rotating plate 71. The fixing plate 73 is L-shaped. A spring plate 74 is fixedly connected to one side of the top of the support 2 to provide restoring force to the rotating plate 71, ensuring that the guide wheel 72 can always maintain contact with the optical fiber sleeve and rotate as it moves. One end of the spring plate 74 is fixedly connected to one end of the fixing plate 73.

[0036] The operation of the fiber optic sleeve crack detection device provided by this utility model is as follows: During detection, one end of the fiber optic sleeve rests on the guide wheel 72, then passes between the second limiting roller 64 and the first limiting roller 54, corresponding to the position of the detection seat 3. Then, the operator turns the knob 66 ​​to rotate the threaded rod 65, which in turn causes the moving plate 61 to move the second limiting roller 64 towards the first limiting roller 54 under the limiting action of the through plate 63 and the hollow plate 62. This cooperates with the first limiting roller 54 to limit the passing fiber optic sleeve, preventing it from deviating too much and ensuring that one end is aligned with the detection seat 3 for detection. Furthermore, during the transport of the fiber optic sleeve, the guide wheel 72, which supports the fiber optic sleeve, moves to its highest position under the action of the spring plate 74. This cooperates with the pull-in structure inside the equipment box 1 to keep the end of the fiber optic sleeve being detected taut.
