Description

Technical Field

[0001] This utility model relates to the field of optical fiber disks, and more particularly to an optical fiber disk structure. Background Technology

[0002] With technological advancements and increasingly stringent quality control requirements for end products, the application of lasers is receiving growing attention and emphasis. This ranges from low-power lasers used in medical applications (skin repair, nerve repair, etc.), consumer electronics (facial recognition, etc.), and automotive LiDAR, to medium- and high-power lasers used in industrial processing (welding, cutting, marking, etc.) and military / scientific research applications.

[0003] Whether for low-power or medium-to-high-power laser products, ensuring the quality of the output laser requires specific technical specifications regarding the active fiber length and resonant cavity. This is especially true for medium-to-high-power laser products, where length requirements range from a few meters to tens or even hundreds of meters. This necessitates addressing the need for protection and neat, standardized coiling of hundreds of meters of fiber, leading to the development of "fiber optic tray structures." Currently, most fiber optic tray structures on the market have uneven fiber placement grooves, and the sharp edges of these steps pose a high probability of fiber damage during handling, requiring operators with a high level of skill in coiling the fiber. Utility Model Content

[0004] The main objective of this invention is to provide an optical fiber disk structure that addresses the aforementioned technical problems.

[0005] To achieve the above objectives, the present invention proposes an optical fiber disk structure comprising an optical fiber disk body, wherein an optical fiber placement groove is provided on the optical fiber disk body, the optical fiber placement groove comprising an inlet guide groove, an outlet guide groove, and multiple loops of optical fiber grooves connecting the inlet guide groove and the outlet guide groove.

[0006] In one embodiment, the depth of the fiber guide groove extends from high to low along the direction of entering the fiber groove, and the depth of the fiber guide groove extends from low to high along the direction of exiting the fiber groove.

[0007] In one embodiment, the optical fiber disk body is further provided with grating placement slots located on the left and right sides of the optical fiber placement slot.

[0008] In one embodiment, the two ends of the grating placement slot transition from the bottom of the slot towards the middle to the main plane of the optical fiber disk.

[0009] In one embodiment, the fiber optic disk body is provided with two cladding stripper placement slots located on one of the left and right sides and one of the top and bottom sides.

[0010] In one embodiment, the two ends of the cladding stripper placement slot transition from the bottom of the slot towards the middle to the main plane of the optical fiber disk.

[0011] In one embodiment, the fiber optic disk body is provided with a pump fiber entry path guide groove.

[0012] In the technical solution of this utility model, the fiber optic tray structure includes a fiber optic tray body, on which a fiber placement groove is formed. The fiber placement groove includes an input fiber guide groove, an output fiber guide groove, and multiple loops of fiber grooves connecting the input fiber guide groove and the output fiber guide groove. In this application, by setting the input fiber guide groove and the output fiber guide groove, the difficulty of fiber optic tray operation can be reduced, thereby optimizing production yield and reducing rework costs caused by damage.

[0029] This utility model provides an optical fiber disk structure.

[0030] like Figure 1-3As shown, the fiber optic disk structure provided in this embodiment of the present invention includes a fiber optic disk body 10, on which a fiber optic placement groove 20 is provided. The fiber optic placement groove 20 includes an inlet fiber guide groove 21, an outlet fiber guide groove 22, and a multi-turn fiber optic groove 23 connecting the inlet fiber guide groove 21 and the outlet fiber guide groove 22.

[0031] In this embodiment, by setting the fiber inlet guide groove 21 and the fiber outlet guide groove 22, the difficulty of fiber coiling can be reduced, thereby optimizing the production yield and the repair cost caused by damage.

[0032] For details, please refer to Figure 2 and Figure 3 The depth of the fiber inlet guide groove 21 extends from high to low along the direction of entering the fiber groove 23, and the depth of the fiber guide groove extends from low to high along the direction of exiting the fiber groove 23. The orientation of the fiber inlet guide groove 21 and the fiber outlet guide groove 22 can be adjusted in angle and orientation according to the optical scheme and fiber winding specifications, but a smooth transition (from high to low and / or from low to high) must be ensured, so as to protect the YB fusion splice and provide the operator with a clear fiber winding path, reducing the difficulty of operation.

[0033] Please refer to Figure 4-5 The fiber optic disk body 10 is also provided with grating placement slots 30 located on the left and right sides of the fiber placement slot 20. The grating devices are mostly cylindrical and generate heat during operation. Therefore, the grating placement slots 30 with appropriate length, width, and depth can be designed according to the diameter and size of the grating, which can both pre-fix the devices and optimize the heat conduction performance. The two ends of the grating placement slots 30 transition evenly from the lowest recessed position to the reference plane of the fiber optic disk, avoiding stress-induced warping or damage to the optical fiber.

[0034] Similarly, please refer to Figure 6-8 The two ends of the grating placement slot 30 transition from the bottom of the slot towards the middle to the plane of the fiber optic disk body 10. The fiber optic disk body 10 has two cladding stripper placement slots 40 located on one of the left and right sides and one of the top and bottom sides. The cladding strippers 60 are mostly cylindrical and generate significant heat during operation. The cladding stripper placement slots 40 are designed with appropriate length, width, and depth based on the diameter and size of the device, serving both as pre-fixing devices and optimizing thermal conductivity. The lowest point of the cladding stripper placement slots 40 should evenly transition to the fiber optic disk reference plane to prevent the fiber from warping or being damaged due to stress.

[0035] In other embodiments, the opening position and orientation of the grating placement slot 30 and the cladding stripper placement slot 40 can be adjusted according to the optical scheme. In this application, the optical devices are pre-fixed by the grating placement slot 30 and the cladding stripper placement slot 40, which saves the material cost of auxiliary fixing and avoids damage to the optical fiber caused by the rolling of the device before auxiliary fixing.

[0036] Additionally, please refer to Figure 9 The fiber optic disk body 10 is provided with a pump fiber entry path guide groove 50. The pump fiber entry path guide groove 50 can protect the pump fiber, thereby eliminating the need for fiber optic protective sleeves and reducing costs. It also provides operators with a clear fiber path, reducing the difficulty of operation, and the angle and direction can be adjusted according to the pump position and fiber winding specifications.

[0037] Furthermore, if the fiber optic disk body 10 needs to be sealed, the sealing performance of the fiber optic disk body 10 can be optimized by pumping the fiber optic cable into the fiber optic disk path guide groove 50.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
