Description

Technical Field

[0001] This utility model relates to the field of optical cable diameter detection technology, and in particular to a diameter detection device for optical cable processing. Background Technology

[0002] Optical fiber cables are communication cable assemblies that use one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. Optical fiber cables are mainly composed of optical fibers (glass filaments as thin as a hair), a plastic protective sheath, and a plastic outer sheath. The optical fiber cable industry has established a series of standards and specifications regarding optical fibers, including requirements for fiber diameter; therefore, diameter testing is necessary during the manufacturing process of optical fibers.

[0003] The advantages of diameter detection during optical cable processing are mainly reflected in the following aspects:

[0004] 1. Ensure the optical performance of the optical cable: The diameter of the optical cable affects the transmission mode and efficiency of the optical signal. If the diameter of the optical cable does not meet the specifications, it may lead to increased transmission loss of the optical signal, thereby affecting the communication quality. Moreover, changes in the diameter of the optical cable may cause attenuation of the optical signal. By detecting the diameter of the optical cable, it can be ensured that the diameter of the optical cable is within the allowable error range, thereby reducing the attenuation of the optical signal and improving the performance of the communication system.

[0005] 2. Ensuring the mechanical properties of optical cables: By testing the diameter of the optical cable, it can be ensured that the tensile strength of the cable meets the design requirements, thereby improving the safety and reliability of the optical cable during laying and use. Moreover, optical cables may be subjected to various external forces during use, such as pressure and bending. The diameter of the optical cable affects its compressive strength. By testing the diameter of the optical cable, it can be ensured that the optical cable can maintain its structural integrity when subjected to external forces, thereby extending the service life of the optical cable.

[0006] Currently, the diameter detection device with existing technology publication numbers CN218066240U and CN221925054U can be used to detect the diameter of optical cables. However, the existing technology requires the use of a clamping structure to fix the optical cable before detection. The clamping pressure applied to the optical cable can easily cause the optical cable to deform, affecting the accuracy of diameter measurement. Moreover, after detection, the clamping structure needs to be loosened, and the next batch of optical cables needs to be replaced and fixed before detection. The operation is cumbersome and the detection efficiency is low. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a diameter detection device for optical cable processing. The technical problem to be solved by this utility model is: how to improve the detection accuracy and efficiency of optical cables.

[0008] This utility model provides a diameter detection device for optical cable processing, including a frame. The frame is provided with an optical cable laying frame and an optical cable take-up frame distributed on the left and right. At least one optical cable reel is fitted on the optical cable laying frame, and the optical cable take-up frame is fitted with an empty cylinder of the same number as the optical cable reel. The optical cable from the optical cable reel is pulled out and wound around the empty cylinder. The optical cable between the optical cable reel and the empty cylinder becomes the optical cable segment to be tested.

[0009] The frame is equipped with a diameter detection component located at the top of the optical cable segment to be tested. The diameter detection component includes a laser rangefinder and a horizontal drive device. The horizontal drive device is used to drive the laser rangefinder to move back and forth to detect the diameter of the optical cable segment to be tested. The laser rangefinder is an instrument that uses laser technology to measure distance. It has the ability to measure distances with high precision, high speed and long distance. Its ranging principle is to shoot a beam or a sequence of short pulse laser beams toward the target, and the laser beam reflected by the target is received by a photoelectric element. A timer measures the time from the emission to the reception of the laser beam, and the distance from the observer to the target is calculated based on the speed of light.

[0010] In one embodiment, a horizontal platform is fixed on the frame between the optical cable laying frame and the optical cable take-up frame. The horizontal platform includes a horizontal plate and a lifting drive device fixed to the bottom of the horizontal plate. The lifting drive device is fixed on the frame, and the horizontal plate is located at the bottom of the optical cable segment to be tested.

[0011] In one embodiment, telescopic rods are fixed at the four corners of the bottom of the horizontal plate, and the four telescopic rods are fixed on the frame to guide the up and down movement of the horizontal plate.

[0012] In one embodiment, each optical cable segment to be tested is provided with two sets of optical cable guide assemblies distributed on the left and right sides at the top. The optical cable guide assembly includes a guide wheel and a connecting rod fixed to the top of the guide wheel. The connecting rod is fixed on the frame, and the guide wheel is in contact with the outer wall of the optical cable segment to be tested.

[0013] In one embodiment, the optical cable laying frame and the optical cable take-up frame have the same structure. The optical cable laying frame includes a base and a support plate fixed to the rear side of the top of the base. A support rod is fixed to the front end of the support plate, and at least one limiting ring is threaded onto the support rod.

[0014] In one embodiment, a control panel is fixed to the front side of the frame for receiving measurement data.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. Optical cable is wound and wound up using optical cable laying rack and optical cable take-up rack, so that the optical cable between the optical cable drum and the empty drum becomes the optical cable segment to be tested. The diameter detection component detects the diameter of the optical cable segment to be tested. After one optical cable segment is tested, the winding continues to replace the optical cable segment to be tested and continue the measurement, so as to provide more measurement data and improve the detection accuracy. Compared with the prior art, this utility model can conveniently and quickly replace the optical cable segment to be tested without making the optical cable messy, which greatly improves the detection efficiency.

[0017] 2. By installing multiple sets of optical cable reels and empty reels on the optical cable laying frame and optical cable take-up frame respectively, the diameter of optical cables on multiple optical cable reels can be detected simultaneously, thereby further improving the detection efficiency.

[0030] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0031] This utility model provides a diameter detection device for optical cable processing, such as... Figure 1-5 As shown, the device includes a frame, with a control panel 8 fixed to the front side of the frame for receiving measurement data. The frame is equipped with a fiber optic cable delivery rack 1 and a fiber optic cable take-up rack 2 distributed left and right. At least one fiber optic cable reel 3 is fitted onto the fiber optic cable delivery rack 1, and the same number of empty reels 9 as the fiber optic cable reels 3 are fitted onto the fiber optic cable take-up rack 2. The fiber optic cable delivery rack 1 and the fiber optic cable take-up rack 2 have the same structure. The fiber optic cable delivery rack 1 includes a base 11 and a support plate 12 fixed to the rear top of the base 11. A support rod 13 is fixed to the front end of the support plate 12. The fiber optic cable reels 3 are fitted onto the support rod 13, and at least one limiting ring 14 is threaded onto the support rod 13.

[0032] This embodiment takes the example of two optical cable reels 3 on the optical cable laying frame 1 and two empty reels 9 on the optical cable take-up frame 2: First, one optical cable reel 3 is placed on the support rod 13 of the optical cable laying frame 1. Then, a limiting ring 14 is screwed onto the support rod 13 to limit the first optical cable reel 3. Then, the second optical cable reel 3 is placed on the support rod 13 of the optical cable laying frame 1. Then, another limiting ring 14 is screwed onto the support rod 13 to limit the second optical cable reel 3. Figure 4 As shown.

[0033] Similar to the steps described above, two empty cylinders 9 are placed on the optical cable take-up frame 2. Then, the optical cable from the optical cable reel 3 is pulled out and wound around the empty cylinders 9. The optical cable between the optical cable reel 3 and the empty cylinders 9 becomes the optical cable segment 4 to be tested. That is, in this embodiment, there are two optical cable segments 4 to be tested. A motor or other driving device for driving the support rod 13 to rotate is installed on the optical cable pay-off frame 1 and the optical cable take-up frame 2, which can drive the optical cable reel 3 to perform pay-off operation and the empty cylinders 9 to perform take-up operation.

[0034] like Figure 1-3 As shown, a diameter detection component 5 is mounted on the frame at the top of the optical cable segment 4 to be tested. The diameter detection component 5 includes a laser rangefinder 51 and a horizontal drive device 52. The horizontal drive device 52 can be a linear module, an electric push rod, an electric cylinder, or other similar device. The horizontal drive device 52 drives the laser rangefinder 51 to move back and forth to detect the diameter of the optical cable segment 4 under test. The laser rangefinder 52 can be a Bosch GLM 100-25 C model, with a measuring range of 0.08-100 meters and an accuracy of ±1.5 mm.

[0035] like Figure 1-2 As shown, a horizontal platform 6 is fixed on the frame between the optical cable laying frame 1 and the optical cable take-up frame 2. The horizontal platform 6 includes a horizontal plate 61 and a lifting drive device 62 fixed to the bottom of the horizontal plate 61. The lifting drive device 62 is fixed on the frame. The horizontal plate 61 is located at the bottom of the optical cable segment 4 to be tested. The lifting drive device 62 can be an electric push rod, an electric cylinder or other device to adjust the height of the horizontal plate 61 so that the horizontal plate 61 and the optical cable segment 4 to be tested have a suitable distance.

[0036] The horizontal plate 61 is fixed with four telescopic rods 63 at its bottom corners. The four telescopic rods 63 are fixed on the frame and are used to guide the vertical movement of the horizontal plate 61. In order to further ensure the horizontality of the horizontal plate 61, a level can be installed on the horizontal plate 61. The principle of the level is: using the characteristic that the bubble is always at the highest point in the glass tube, when the level is tilted, the bubble will move to the higher end, thereby determining whether the horizontal plate 61 is horizontal.

[0037] To ensure that the optical cable segment 4 under test is horizontal, two sets of optical cable guide components 7 are provided on the top of each optical cable segment 4, distributed from left to right. The optical cable guide component 7 includes a guide wheel 71 and a connecting rod 72 fixed to the top of the guide wheel 71. The connecting rod 72 is fixed on the frame. The guide wheel 71 is in contact with the outer wall of the optical cable segment 4 under test. When the two guide wheels 71 on the optical cable segment 4 under test are at the same height, the optical cable segment 4 under test between the two guide wheels 71 is restricted to be horizontal.

[0038] The principle behind this device for detecting the diameter of optical cables is as follows:

[0039] First, the optical cable reel 3 to be tested is placed on the support rod 13 of the optical cable laying frame 1. Then, the upper limit ring 14 is screwed on the support rod 13 of the optical cable laying frame 1 to limit the optical cable reel 3 and prevent the optical cable reel 3 from falling. Then, the empty cylinder 9 is placed on the support rod 13 of the optical cable take-up frame 2. Then, the upper limit ring 14 is screwed on the support rod 13 of the optical cable take-up frame 2 to limit the empty cylinder 9 and prevent the empty cylinder 9 from falling. Then, the optical cable of the optical cable reel 3 is pulled out, passes around the bottom of the guide wheel 71, and is wound around the empty cylinder 9. Then, the optical cable laying frame 1 and the optical cable take-up frame 2 perform the cable laying and take-up operation. At this time, the optical cable between the optical cable reel 3 and the empty cylinder 9 becomes the optical cable segment 4 to be tested.

[0040] At this time, the laser rangefinder 51 is located at the front of the horizontal plate 61. Then, the laser emitted by the laser rangefinder 51 is activated and first shines on the horizontal plate 61, which can measure the distance C between the laser rangefinder 51 and the horizontal plate 61. Then, the horizontal drive device 52 is activated to drive the laser rangefinder 51 to move from front to back, so that the laser of the laser rangefinder 51 passes through the optical cable segment 4 to be measured. The shortest distance measured by the laser rangefinder 51 during the movement is B. The distance A between the horizontal plate 61 and the optical cable segment 4 to be measured can be measured in advance. Then, the diameter D of the optical cable segment 4 to be measured is CAB.

[0041] After the optical cable segment 4 under test is completed, the cable is wound up to replace the optical cable segment 4 under test and continue to measure, so as to provide more measurement data and improve the detection accuracy. This utility model can conveniently and quickly replace the optical cable segment 4 under test without making the optical cable messy, thus greatly improving the detection efficiency.

[0042] In addition, multiple sets of optical cable reels 3 and empty reels 9 can be installed on the optical cable laying frame 1 and the optical cable take-up frame 2 respectively, so as to realize the diameter detection of optical cables on multiple optical cable reels 3 at the same time, and further improve the detection efficiency.

[0043] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
