[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0042] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides a 3D printing-based optical cable sheath rotation repair device, comprising:

[0043] Base 100;

[0044] and, a 3D printing nozzle 200 disposed on the base 100;

[0045] Also included is a rotating mechanism 300 for rotating the optical cable.

[0046] In this embodiment, the optical cable to be repaired is placed on the rotating mechanism 300, the portion to be repaired is printed and repaired by the 3D printing nozzle 200, and the portion of the optical cable to be repaired is changed by the rotating mechanism 300 to complete the repair of the optical cable.

[0047] Specifically, a fixing clamp 301 for clamping the optical cable is provided in the rotating mechanism 300. In the present embodiment, the setting of the fixing clamp 301 facilitates the operator to fix the optical cable on the rotating mechanism 300. The design of the clamp can adapt to optical cables of different diameters, ensuring that the optical cable is firmly fixed on the equipment without movement or shaking.

[0048] Furthermore, a limiting clamp 101 for limiting and supporting the surface of the optical cable is provided on the base 100. In the present embodiment, the limiting clamp 101 may be a U-shaped structure, which is convenient for limiting the position of the optical cable, and can provide support for the surface of the optical cable to improve the repair effect.

[0049] Among them, a transmission device 201 is provided on the 3D printing nozzle 200, and the transmission device 201 can control the 3D printing nozzle 200 to move in all directions such as up, down, left, right, front and back. In this embodiment, the setting of the transmission device 201 can enable the 3D printing nozzle 200 to move and displace, thereby facilitating the change of the printing location.

[0050] Preferably, a position sensor 202 for detecting the position of the 3D printing nozzle 200 is further included. In this embodiment, the arrangement of the position sensor 202 facilitates precise control of the position of the 3D printing nozzle 200 .

[0051] It should be noted that the rotatable angle of the rotating mechanism 300 is at least 120°. In the present embodiment, the rotation of the rotating mechanism 300 can facilitate printing and repairing of different parts, and its rotation angle is greater than 120°. During repair, the optical cable only needs to be rotated three times to complete the repair of all positions on the surface. In addition, the 120° setting will not affect printing due to the setting of the limit clamp 101 during printing.

[0052] Further explanation of the problems existing in the existing optical cable sheath repair technology:

[0053] 1. Repair accuracy problem: The traditional glue injection repair process is difficult to control accurately, and the fluidity of the glue will cause it to be unevenly distributed on the outer sheath of the optical cable. For example, when injecting glue, the glue may accumulate too much in certain parts of the optical cable due to gravity, forming a glue layer with inconsistent thickness. Moreover, for some small damaged parts, the glue may not be accurately filled, resulting in the repaired outer sheath not fitting tightly with the optical cable and gaps. 3D printing repair can accurately control the deposition position and thickness of the repair material according to the preset program and model. It can achieve high-precision repair of the outer sheath of the optical cable, so that the repair material is evenly covered on the damaged part and fits the shape of the optical cable closely. Whether it is a tiny scratch or a large area of ​​damage, 3D printing can accurately deposit the material where it needs to be repaired, ensuring that the surface of the repaired outer sheath is flat and the thickness is uniform.

[0054] 2. Material performance issues: The glue material properties used in traditional glue injection repair are relatively single. General glue may have limited performance in terms of high temperature resistance, corrosion resistance, and wear resistance, and it is difficult to meet the requirements of the optical cable sheath in different use environments. For example, in a high temperature environment, the glue may soften, causing the repaired sheath to lose its protective effect; in an environment with chemical corrosion, the glue may be corroded, thereby affecting the performance of the optical cable. 3D printing repair can choose a variety of suitable materials for repair. It can select materials with corresponding properties according to the specific environment in which the optical cable is located, such as severe outdoor weather, industrial chemical environment, underground humid environment, etc. For example, high temperature resistant, high-strength engineering plastics or composite materials with good corrosion resistance can be used to enhance the performance of the repaired sheath and extend the service life of the optical cable.

[0055] 3. Operational complexity: Traditional glue injection repair operations are relatively complicated, and the optical cable needs to be pre-processed, such as cleaning and polishing, to ensure that the glue can adhere well. During the glue injection process, the injection speed and amount of glue need to be controlled, which places high technical requirements on the operator. Moreover, after the injection, it is necessary to wait for the glue to solidify, which takes a long time, and the entire repair process is time-consuming and laborious. The 3D printing repair operation is relatively simple. You only need to fix the optical cable on the equipment and set the printing parameters, such as printing speed, nozzle rotation speed, material type, etc., and the equipment can be repaired according to the preset program. The operator does not need to have superb manual skills, and the printing process is relatively fast, which reduces the repair time and improves work efficiency.

[0056] Repair quality stability issues: The quality stability of traditional glue injection repairs is poor. Since the curing process of glue is greatly affected by environmental factors such as temperature and humidity, the curing effect of glue may be different under different environmental conditions, resulting in uneven quality of the outer skin after repair. Moreover, the bonding strength between the glue and the outer skin of the optical cable may not be ideal, and debonding is prone to occur during long-term use. 3D printing repairs can ensure the stability of repair quality through precise material deposition and good material fusion. The printing material and the outer skin of the optical cable can be well combined through appropriate processes, and the curing process is not interfered with by environmental factors. During long-term use, the outer skin repaired by 3D printing can maintain good integrity and stability, providing reliable protection for the optical cable.

[0057] Example 2, reference Figure 1 to Figure 3 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a 3D printing-based optical cable sheath rotation repair method, which is applied to a 3D printing-based optical cable sheath rotation repair device, including:

[0058] Select printing materials according to the material of the optical cable;

[0059] Pre-treat the repair area;

[0060] Place the optical cable on the 3D-printed optical cable sheath rotation repair device;

[0061] Set printing parameters;

[0062] Print in stages according to printing parameters;

[0063] Repair completed.

[0064] Specifically, the phased printing includes:

[0065] Print the first 120° range;

[0066] Print the second 120° range;

[0067] Print a third 120° range.

[0068] Furthermore, the printing parameters include,

[0069] Choice of printing materials;

[0070] Choice of printing speed;

[0071] Selection of nozzle movement speed;

[0072] Selection of print layer thickness.

[0073] Pretreatment of the repair site includes:

[0074] Polish the repaired area;

[0075] Clean the repaired area.

[0076] The rest of the structure is the same as that of Example 1.

[0077] Reference Figure 3 , the repair process is as follows:

[0078] Preparation stage: Check whether all parts of the equipment are operating normally, including the rotating mechanism 300, the 3D printing nozzle 200, the control system, etc. Ensure that the power supply, gas source, water source, etc. of the equipment are normal, and the connection between the parts is firm and reliable. According to the damage of the cable sheath and the repair requirements, select suitable printing materials, such as high temperature resistant, corrosion resistant, high strength engineering plastics or composite materials. Pre-treat the optical cable, such as cleaning and polishing, to ensure that the surface of the cable sheath is clean and flat, which is conducive to the adhesion of the printing material.

[0079] Fixing the optical cable: Place the optical cable to be repaired on the base 100, clamp and fix it with the fixing clamp 301, and adjust the position and angle of the optical cable so that the fixing clamp 301 can firmly fix the optical cable and is in the limiting clamp 101. Ensure that the optical cable does not move or shake during the repair process to ensure the quality of the repair.

[0080] Set parameters: Set repair parameters through the human-machine interface, such as printing material, printing speed, nozzle movement speed, printing layer thickness, etc. According to the damage of the cable sheath and the repair requirements, reasonably set the printing parameters to ensure the quality and efficiency of the repair. Parameters can be optimized according to actual conditions, such as adjusting the printing parameters through trial printing to obtain the best repair effect.

[0081] Printing in stages:

[0082] a. Print the first 120° range: Driven by the transmission device 201, the 3D printing nozzle 200 moves to the starting position above the optical cable and starts printing and repairing the 120° range above the optical cable. The control system monitors the position, status and printing progress of the nozzle in real time, and adjusts the printing parameters according to the information fed back by the sensor to ensure the printing quality and accuracy;

[0083] b. Print the second 120° range: When the first 120° range is printed, stop the movement of the 3D printing nozzle 200. Use the rotating mechanism 300 to rotate the device 120° clockwise to align the 3D printing nozzle 200 with the next 120° range to be printed. The 3D printing nozzle 200 is started again to print and repair the new 120° range. The printing process is similar to the first 120° range. The control system adjusts the printing parameters according to the actual situation to ensure consistent repair effects;

[0084] c. Print the third 120° range: When the second 120° range is printed, stop the movement of the 3D printing nozzle 200. Continue to rotate the device 240° counterclockwise through the rotating mechanism 300 to position the nozzle to the last 120° range to be printed. The 3D printing nozzle 200 starts to print the cable sheath of the last 120° range. The control system continues to precisely control to ensure the repair quality of the entire cable sheath.

[0085] Complete the repair: When the third 120° range is printed, turn off the device and wait for the printed material to cool and solidify. The curing time of the printed material should be determined according to factors such as the material characteristics and ambient temperature. Ensure that the material is completely cured before proceeding to the next step. Take out the repaired optical cable and check whether the repair effect meets the requirements. The repaired optical cable sheath can be evaluated by appearance inspection, performance testing, etc. to ensure that the repair quality meets the expected requirements.

[0086] Beneficial effects compared with previous technologies:

[0087] 1. Precise size control: The traditional glue injection method makes it difficult to control the uniformity of glue thickness. 3D printing deposits glue layer by layer with high precision according to the preset model, achieving micron-level size accuracy, ensuring that the repaired outer skin perfectly matches the original optical cable and avoiding signal transmission problems.

[0088] 2. Adapt to complex shapes: The shapes of optical cable damage are diverse, and traditional glue injection methods are difficult to repair special shapes. 3D printing can customize repairs according to actual shapes, flexibly adjust the nozzle to fill complex areas, achieve seamless fitting, and improve repair quality and reliability.

[0089] 3. Excellent material performance: Traditional injection glue has limited performance and is difficult to meet the requirements of use in harsh environments. 3D printing can use high-performance materials such as high-temperature resistant plastics, corrosion-resistant composite materials, etc. The materials are selected according to the environment and requirements to ensure the performance of the outer skin after repair and improve the quality and reliability of the optical cable.

[0090] 4. Improve repair efficiency: Traditional glue injection repair steps are cumbersome, including pretreatment, material mixing and manual operation, which is time-consuming and relies on manual experience. The 3D printing repair process is simplified. After checking the equipment, loading and fixing the optical cable in the preparation stage, the parameters are set and the equipment prints automatically. There is no need for complex manual operation and material mixing, which greatly shortens the repair time and improves work efficiency.
