[0045] In the production of semiconductor lasers, fiber coupling is required. Currently, fiber coupling operations are generally carried out using automated equipment to improve production efficiency. However, traditional coupling tray structures are typically designed for coupling single fibers. In actual production, the coupling trays need to be frequently switched, which is not conducive to optimizing and reducing working hours, and production efficiency needs further improvement.

[0046] This invention proposes an optical fiber coupling disk 100 to solve the above problems.

[0047] Please see Figures 1 to 2 In one embodiment of this utility model, the optical fiber coupling disk 100 includes a plate 1, a fixing member, and a coiling fixing assembly 5. The plate 1 includes a fixing surface 11 disposed in its thickness direction. The fixing member includes a first fixing part 2 and a second fixing part 4. The first fixing part 2 and the second fixing part 4 are respectively disposed at both ends of the plate 1 and are both used to fix one end of multiple optical fibers at the same time. The first fixing part 2 is rotatably mounted on the plate 1 about an axis perpendicular to the fixing surface 11 for automatic switching of coupling optical fibers. The coiling fixing assembly 5 is disposed on the fixing surface 11 for auxiliary fixing of excessively long optical fibers.

[0048] The fiber optic coupling disk 100 is mainly used for feeding and fixing optical fibers during the fiber coupling process. Existing fiber coupling operations generally rely on automated equipment to improve production efficiency. However, traditional coupling disk structures are typically designed for coupling single optical fibers. In actual production, the coupling disk needs frequent switching, which is not conducive to optimizing and reducing working hours, and production efficiency needs further improvement. In this embodiment, the fiber optic coupling disk 100 is not a single-fiber fixing structure 22. In actual use, multiple optical fibers to be processed can be simultaneously fixed on the fixing surface 11 of the plate 1. Specifically, in the actual operation, that is, in the material preparation stage, one end of multiple optical fiber materials can be fixed simultaneously to the first fixing part 2, and then the other end of multiple optical fiber materials can be fixed simultaneously to the second fixing part. Ideally, after the optical fiber is fixed in the above manner, the optical fiber should be in contact with the fixing surface 11 or the distance between the two should be very small. This is because in actual material preparation, multiple optical fiber coupling discs 100 need to be stacked vertically. Therefore, if the middle position of the optical fiber is raised too high or protrudes from the periphery of the plate 1, it is very likely to interfere with the external structural components during the automatic feeding process, which will lead to production instability. Therefore, in this embodiment, the coiling fixing component 5 is provided near the middle position of the plate 1. In the actual fixing process, the excessively long optical fiber can be coiled and then placed on the fixing surface 11. The coiling fixing component 5 fixes the coiled optical fiber, thereby ensuring that the excessively long optical fiber does not protrude from the periphery of the plate 1 or show a raised state in the vertical direction. At this point, the multiple optical fibers are in a relatively stable fixed state on the plate 1, further improving stability during loading, unloading, and coupling in actual production. It should also be noted that the first fixing component in this embodiment is a movable fixing component, capable of rotating at a certain angle on the fixing surface 11, allowing the ends of the multiple optical fibers to switch at the coupling position. Compared to the traditional single fixing method, this method of directly switching optical fibers for coupling on the plate 1 is much faster, avoiding the current situation of frequently switching material trays for loading and unloading, and greatly improving production efficiency.

[0049] The first fixing part 2 includes a rotating mounting part and a plurality of fixing structures 22. The rotating mounting part is rotatably mounted on the plate 1 with an axis perpendicular to the fixing surface 11. The plurality of fixing structures 22 are all mounted on the rotating mounting part around the rotation axis of the rotating mounting part to fix the end of the optical fiber.

[0050] The above implementation example Figure 1As shown, when fixing the ends of multiple optical fibers, the ends of multiple optical fibers need to be fixed to multiple fixing structures 22 respectively. The multiple fixing structures 22 are installed on the rotating mounting part around the rotation axis of the rotating mounting part. In actual design, it is preferable to set the multiple fixing structures 22 at equal intervals on the same arc. After such setting, in the actual processing and production process, it is only necessary to control the rotating mounting part to rotate a specific angle each time it switches to complete the processing and switching between multiple optical fibers, which is more conducive to simplifying the control process.

[0051] like Figures 1 to 3 To achieve efficient fiber coupling production, the rotation drive of the rotating mounting part is electrically driven. A corresponding connection structure is provided on the fiber coupling disk 100, which can be connected to the electrically driven structure on the production equipment. Specifically, the fiber coupling disk 100 has multiple reference holes, which can cooperate with positioning pins and other structures on the processing equipment. This ensures the accuracy of the coupling disk structure position each time it is replaced, and further guarantees the consistency of the fiber end positions on the first fixing part 2 and the second fixing part 4.

[0052] The plate 1 is provided with a rotating shaft 12, which is arranged through the plate 1 in the thickness direction. The rotating mounting part is provided at one end of the rotating shaft 12 corresponding to the fixed surface 11. The end of the rotating shaft 12 away from the fixed surface 11 is provided with an adapter for connecting with an external driving component.

[0053] In actual production, the fiber optic coupling disk 100 is placed on the processing station. At this time, the multiple reference holes and the positioning structure on the processing station are matched, thereby limiting the entire plate 1 to its accurate position on the processing station. In this state, the adapter on one end of the rotating shaft 12 connects to the output end of the drive structure on the processing station. The drive structure operates intermittently; upon receiving a start signal, it drives the rotating shaft 12 to rotate by a specific angle, thereby switching the processing fiber at the coupling structure.

[0054] It is conceivable that the adapter part is not difficult to implement. To facilitate the connection between the rotating shaft 12 and the output end of the drive structure, the adapter part can be set as an equilateral hole structure on the end of the rotating shaft 12, such as a hexagonal hole or a triangular hole. Correspondingly, the drive structure can be set as a motor component, and a rhombus-shaped shaft structure corresponding to the hole structure can be set on the output shaft of the motor component. During the adaptation process, the rhombus-shaped shaft structure is directly inserted into the corresponding equilateral hole structure. When the electrode component is working, it can simultaneously drive the rotating shaft 12 to rotate.

[0055] In addition to the above embodiments, the adapter can also be configured as an electromagnetic structure, with a magnet at one end of the rotating shaft 12 and an electromagnetic structure at the output end of the drive unit on the processing station of the production equipment. When energized, the electromagnetic structure can form a good connection with one end of the rotating shaft 12, thereby driving the rotating shaft 12 to rotate. Many structures are possible for the adapter, and no limitation is made here. In actual processing and production, the appropriate structure can be selected based on the availability and requirements of the actual production materials.

[0056] In one embodiment of this utility model, preferably, the rotating mounting part is configured as a sector plate 21 structure, the center of the sector plate 21 is rotatably mounted on one end of the rotating shaft part 12 corresponding to the fixed surface 11, and a plurality of the fixed structures 22 are evenly arranged on the sector plate 21 around the center of the sector plate 21.

[0057] The rotating mounting part is configured as a fan-shaped structure, and multiple fixing structures 22 are evenly spaced around the center of the fan-shaped plate 21. This arrangement allows for the relatively concentrated fixing of one end of each optical fiber within the same area of ​​the fan-shaped plate 21. During actual processing, the external drive structure can rotate the rotating shaft 12 by a small angle to achieve the switching operation. Simultaneously, with the smaller rotation angle during switching, the overall rotation angle of the entire fan-shaped plate 21 will not be too large when the two outermost optical fiber ends are coupled. This significantly reduces the bending deformation of the multiple optical fiber structures. For the optical fiber structure, this ensures the best possible coupling quality and the accuracy of the coupling data during production.

[0058] Among them, such as Figure 1 , Figure 3 and Figure 4 As shown, the fixing structure 22 includes a mounting base 221 and a fixing base 222. The mounting base 221 is disposed on the sector plate 21, and the mounting base 221 is provided with a receiving groove 2211 arranged in the radial direction of the sector plate 21. The fixing base 222 has a mounting end corresponding to the mounting base 221. The mounting end is provided with a retaining block 2221. The retaining block 2221 has a movement stroke perpendicular to the mounting end. The end of the retaining block 2221 away from the mounting end is provided with a retaining groove 2222 corresponding to the receiving groove 2211. The end of the retaining block 2221 away from the retaining groove 2222 is connected to the mounting end through a first elastic member 2223.

[0059] In actual fiber optic cable fixing, one end of the fiber is first placed in the receiving groove 2211. Then, the end of the fixing base 222 with the retaining block 2221 facing downwards is positioned so that the retaining groove 2222 on the retaining block 2221 corresponds to the receiving groove 2211. The fixing base 222 is then placed on the mounting base 221, allowing the retaining block 2221 to press down on the fiber. The receiving groove 2211 and the retaining groove 2222 limit and fix the fiber. It should be noted that the downward-facing end of the retaining block 2221 protrudes from the mounting end face. Therefore, when the mounting end contacts the upper surface of the mounting base 221, the first elastic element 2223 provides a certain downward pressure, thereby stably fixing the fiber between the receiving groove 2211 and the retaining groove 2222.

[0060] It is conceivable that, in order to enable the receiving groove 2211 and the retaining groove 2222 to fix optical fibers with different circumferences, the shapes of the receiving groove 2211 and the retaining groove 2222 can be optimized. Preferably, the receiving groove 2211 and the retaining groove 2222 can be set as V-shaped grooves. When actually fixing the optical fiber, the two inclined walls of the V-shaped groove limit and fix the optical fiber, thereby fixing optical fibers with different circumferences and further improving the applicability of the entire optical fiber coupling disk 100.

[0061] To ensure the stability of the mounting base 221 and the fixing base 222 after they are engaged, a connector 3 is provided between them to allow for a detachable connection. Specifically, the connector 3 includes a first magnetic attraction part 31 and a second magnetic attraction part 32. The first magnetic attraction part 31 is located on the upward-facing end face of the mounting base 221, and the second magnetic attraction part 32 is located on the mounting end corresponding to the first magnetic attraction part 31. In the above embodiment, the mounting base 221 and the fixing base 222 are engaged through the first magnetic attraction part 31 and the second magnetic attraction part 32, which is very convenient in actual operation.

[0062] Of course, in addition to the structure described in the above embodiment, the connector 3 can also be configured as a snap-fit ​​structure, etc. Alternatively, the mass of the fixing base 222 can be set to be relatively large, and then downward protrusions can be provided at the two side ends of the fixing base 222 corresponding to the optical fiber extension direction. The downward end of the two protrusions protrudes from the mounting end. When the fixing base 222 and the mounting base 221 are actually engaged, the two protrusions can be held at the two side ends of the mounting base 221, thereby ensuring that the mounting base 221 and the fixing base 222 are not prone to relative movement during coupling, and further improving the stability of the engagement between the mounting base 221 and the fixing base 222.

[0063] like Figure 1 , Figure 5 and Figure 6 As shown, the second fixing part 4 is disposed on the end of the plate 1 away from the first fixing part 2. Specifically, the second fixing part 4 includes a plurality of elastic support members 41 and a rotating plate 42. The plurality of elastic support members 41 are disposed on one end of the plate 1. Each elastic support member 41 includes a movable support part, which has a travel distance perpendicular to the fixing surface 11. A fixing groove 4111 along the length direction of the plate 1 is provided on the upward end of the movable support part. The rotating plate 42 is rotatably mounted on the plate 1 with an axis perpendicular to the fixing surface 11, and the rotating plate 42 is disposed corresponding to the upward end of the plurality of movable support members.

[0064] When actually fixing the other end of the optical fiber, multiple optical fiber ends can be placed in multiple fixing slots 4111 respectively. The rotating plate 42 is arranged parallel to the fixing surface 11 and can rotate above multiple elastic support members 41. When the fixing plate rotates above the multiple elastic support members 41, the rotating plate 42 can limit the upward peripheral position of multiple optical fibers. At this time, it can drive the multiple elastic support members 41 to move inward towards the plate body 1 in the direction perpendicular to the fixing surface 11. The restoring force of the elastic support member 41 and the combined action of the rotating plate 42 can fix one end of the optical fiber well in the fixing slot 4111.

[0065] To secure optical fibers with varying circumferences, the fixing groove 4111 can also be configured as a V-groove. And as... Figure 5As shown, the rotating plate 42 is installed in a concealed manner. A recessed groove 13 is provided on one end of the plate body 1. Two rotating mounting grooves (not shown in the figure) are provided on the two vertical side walls of the recessed groove 13. One end of the rotating plate 42 is rotatably installed in one of the rotating mounting grooves. When multiple optical fibers are fixed, the other end of the rotating plate 42 is rotated into the other rotating mounting groove. Thus, the rotating plate 42 is kept in a relatively horizontal state as much as possible through the rotating mounting groove, thereby improving its fixing effect.

[0066] The bottom of the sinking trough 13 is provided with a plurality of mounting slots 131. The elastic support member 41 includes a slider part 411 and a second elastic member 412. The slider part 411 is slidably installed in the mounting slot 131. The fixed slot 4111 is provided at the upward end of the slider part 411. The second elastic member 412 is provided in the mounting slot 131, and its upward end is connected to the slider part 411. The slider part 411 includes the movable support part.

[0067] During actual fixing, the optical fiber is initially limited within the fixing groove 4111 at the end of the slider 411. By adjusting the rotation of the rotating plate 42, pressure is applied to the upward peripheral wall of the optical fiber, thereby causing the slider 411 to slide towards the bottom of the mounting groove 131. The combined force of the second elastic element 412 and the rotating plate 42 effectively fixes the end of the optical fiber.

[0068] The fixing surface 11 sinks downward toward the plate 1 to form a limiting groove 14. The coiling fixing assembly 5 includes a rotating pressure plate 51 and a flexible pressure pad 52. The rotating pressure plate 51 is rotatably mounted on the plate 1, and at least one end of the rotating pressure plate 51 corresponds to the limiting groove 14. The flexible pressure pad 52 is disposed on the end face of the rotating pressure plate 51 corresponding to the limiting groove 14. In actual production, there are many types of optical fibers, and the actual length of the optical fiber needs to be changed according to production requirements. The length of the plate 1 is fixed. When fixing, the two ends of the optical fiber are fixed at the two ends of the plate 1. If the optical fiber is long, the optical fiber located in the middle of the plate 1 will deform above the plate 1, which will affect the stability during the production process. Considering the above problems, in this embodiment, the excess optical fiber can be manually coiled first, and then the rotating pressure plate 51 can be rotated to press it down and fix it inside the limiting groove 14. At this time, all the optical fiber in the process is stored inside the plane of the plate 1, so that it will not affect the external structure of the production equipment during the actual feeding process.

[0069] It should be noted that, in order to maintain good transmission performance of the optical fiber on the fixing surface 11 and avoid unnecessary bending, the bottoms of the limiting groove 14 and the recessed groove 13 are kept flush, and the upper surface of the sector plate 21 is also kept flush with the bottom surface of the limiting groove 14. With the optical fiber fixed in this way, both ends are at the same horizontal level, which can also prevent damage to the outer wall of the optical fiber to a certain extent during actual coupling.

[0070] Furthermore, this solution is a feeding and fixing structure 22 in the fiber optic coupling process, adapted to the feeding process in actual automated production. Therefore, in actual production, multiple fiber optic coupling disks 100 need to be stacked at the material hopper location to maintain production efficiency at a high level. Specifically, the fixing surface 11 is provided with multiple upwardly protruding support shafts 15, and the plate body 1 and the fixing surface 11 opposite each other are provided with multiple adapter holes 16 corresponding to the multiple support shafts 15. When two adjacent fiber optic coupling disks 100 are stacked vertically, the upward end of the support shaft 15 on the lower coupling disk structure is inserted into the adapter hole 16 of the upper coupling disk structure, thereby allowing the stacked coupling disks to be positioned vertically and defining a certain vertical space between the two coupling disks, thus protecting the fiber optic material.

[0071] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
