[0003] Fiber combiners are a crucial optical device in laser structures, primarily used to combine optical beams and increase output power.

Furthermore, an air pressure sensor is used to detect the air pressure in the adsorption hole. When the optical fiber is clamped between the two clamping components, the air suction component can apply negative pressure to the adsorption hole, causing the adsorption hole to adsorb the optical fiber between the two clamping components to the inner surface of the positioning groove. Furthermore, the air pressure sensor is used to detect the air pressure in the adsorption hole, and thus accurately determine whether the optical fiber is stably adsorbed in the positioning groove based on the detected air pressure value, thereby achieving the positioning of the optical fiber between the two clamping components, keeping the optical fiber straight, and preventing the optical fiber from being deformed during the etching process of the optical fiber by the etching assembly, thereby further improving the etching accuracy of the optical fiber.

[0052] The embodiments of the present application provide a fiber etching device, which is described in detail below.

[0053] Figure 1 is a schematic diagram of the structure of an embodiment of an optical fiber etching device provided in an embodiment of the present application. As shown in Figure 1, optical fiber etching device 100 includes a base (not shown), a clamping assembly 110, and an etching assembly (not shown). Clamping assembly 110 includes two clamping components 111 spaced apart from each other along a first direction X on the base. These two clamping components 111 are respectively used to clamp an optical fiber 200 to achieve positioning of the optical fiber 200. The etching assembly is used to etch the surface of the optical fiber 200 to form a bonding surface or other structure on the surface of the optical fiber 200.

[0054] The etching assembly includes a laser and a moving mechanism. The laser is used to generate laser light. The moving mechanism is connected to the laser and is used to drive the laser to move so that the laser can etch the optical fiber 200 along the length direction of the optical fiber 200 .

[0055] Specifically, the moving mechanism is used to drive the laser to move along the length of the optical fiber 200. The laser includes a galvanometer assembly located in the optical path of the laser. The galvanometer assembly is used to convert the laser light into a scanning laser light. The scanning laser light has a scanning direction that forms an angle with the length of the optical fiber 200. In other words, the laser light generated by the laser moves along the length of the optical fiber 200 while also oscillating in a direction that forms an angle with the length of the optical fiber 200.

[0056] Alternatively, the moving mechanism can be used to drive the laser to move along the length direction of the optical fiber 200, and drive the laser to move or swing in a direction at an angle to the length direction of the optical fiber 200, so that the laser light of the laser etches the optical fiber 200 along the length direction of the optical fiber 200.

[0057] Of course, the laser light can also be irradiated onto the optical fiber 200 , and the moving mechanism is used to drive the laser light to move along the length direction of the optical fiber 200 , so that the laser light can etch the optical fiber 200 along the length direction of the optical fiber 200 .

[0058] In some embodiments, the optical fiber etching apparatus 100 further includes a tension measuring component (not shown) for measuring the tension applied to the optical fiber 200. Therefore, before etching the optical fiber 200 using the optical fiber etching apparatus 100, the clamping assembly 110 can first clamp the optical fiber 200 and adjust the tension applied to the optical fiber 200. The tension applied to the optical fiber 200 is then measured using the tension measuring component. When the tension applied to the optical fiber 200 is within a predetermined tension range, it indicates that the optical fiber 200 is straightened. The etching assembly can then be used to etch the optical fiber 200, thereby ensuring that the optical fiber 200 remains straight during etching, thereby improving the etching accuracy of the etching assembly on the optical fiber 200 and forming a highly precise bonding surface on the surface of the optical fiber 200.

[0059] In some embodiments, at least one clamping component 111 is slidably connected to the base along the first direction X. The tension measuring component is disposed on the base and connected to the clamping component 111 slidably disposed on the base to detect the tension exerted on the clamping component 111 .

[0060] It can be understood that by making the clamping component 111 slidingly connected to the base along the first direction X and connecting the tension measuring component to the clamping component 111, the tension exerted on the optical fiber 200 will be fed back to the tension measuring component through the clamping component 111 slidingly connected to the base, thereby realizing the measurement of the tension exerted on the optical fiber 200.

[0061] Of course, the tension measuring component can also be set between the optical fiber 200 and the clamping component 111, and the tension measuring component is directly connected to the optical fiber 200. When the optical fiber 200 is subjected to tension, the tension measuring component can directly detect the tension exerted on the optical fiber 200.

[0062] It should be noted that, in the embodiment of the present application, the two clamping components 111 can be respectively connected to the base in a sliding manner along the first direction X, or only one of the clamping components 111 can be connected to the base in a sliding manner along the first direction X. When the two clamping components 111 are respectively connected to the base in a sliding manner along the first direction X, the optical fiber etching device 100 can include two tension measuring components, the two tension measuring components are respectively provided on the base and are connected to the two clamping components 111 in a one-to-one correspondence. Alternatively, the optical fiber etching device 100 can also include one tension measuring component, which is connected to one of the clamping components 111. Of course, the former can further accurately detect the magnitude of the tension applied to the optical fiber 200.

[0063] As shown in Figure 1, the clamping component 111 includes a connecting seat 1111 provided on the base, and a clamping member 1113 movably connected to the connecting seat 1111. The clamping member 1113 has a clamping position (as shown in Figure 1) and a release position. When the clamping member 1113 is in the clamping position, a clamping space 1115 for clamping the optical fiber 200 is formed between the clamping member 1113 and the connecting seat 1111. When the clamping member 1113 is in the release position, the optical fiber 200 is released.

[0064] In some embodiments, the clamping spaces 1115 of the two clamping members 111 extend respectively along the first direction X. Thus, the portion of the optical fiber 200 clamped between the two clamping members 111 can be made straighter. Specifically, a first groove 1114 is provided on the side of the clamping member 1113 facing the connecting seat 1111, and the first groove 1114 passes through the clamping member 1113 along the first direction X. A second groove 1112 is provided on the side of the connecting seat 1111 facing the clamping member 1113, and the second groove 1112 passes through the connecting seat 1111 along the first direction X. When the clamping member 1113 is in the clamping position, the first groove 1114 of the clamping member 1113 and the second groove 1112 of the connecting seat 1111 enclose and form a clamping space 1115. In the first direction X, the clamping spaces 1115 of the two clamping members 111 overlap.

[0065] In some embodiments, the connection base 1111 of the clamping component 111 can be slidably connected to the base along the first direction X, thereby making the clamping component 111 slidably connected to the base along the first direction X. The tension measuring component can be connected to the connection base 1111 of the clamping component 111 or to the clamping piece 1113 of the clamping component 111, and only needs to be able to detect the tension exerted on the optical fiber 200.

[0066] In some embodiments, the optical fiber etching device 100 further includes a torque measurement component (not shown in the figures), which is used to measure the torsional force applied to the optical fiber 200 .

[0067] It is understandable that if the optical fiber 200 is twisted when the clamping assembly 110 clamps the optical fiber 200, when the optical fiber 200 is etched by the etching assembly and then the optical fiber 200 is removed from the clamping assembly 110, the optical fiber 200 will automatically return to a non-twisted state. At this time, the bonding surface or other structures formed by etching on the surface of the optical fiber 200 will be distorted, thereby affecting the accuracy of the bonding surface or other structures of the optical fiber 200.

[0068] The optical fiber etching device 100 provided in the embodiment of the present application measures the torsional force applied to the optical fiber 200 through a torque measuring component. Before etching the optical fiber 200 through the optical fiber etching device 100, the optical fiber 200 can be clamped by the clamping assembly 110 and the torsional force applied to the optical fiber 200 can be adjusted. Then, the torsional force applied to the optical fiber 200 can be measured by the tension measuring component. When the torsional force applied to the optical fiber 200 is within a predetermined torque range, it indicates that the optical fiber 200 is straightened. Then, the optical fiber 200 is etched by the etching assembly, thereby ensuring that the optical fiber 200 remains straight during the etching process, thereby improving the etching accuracy of the optical fiber 200 by the etching assembly, and further forming a high-precision bonding surface or other structure on the surface of the optical fiber 200.

[0069] In some embodiments, the torque measurement component includes a torque sensor, which is disposed on the side of the clamping member 1113 or the connecting seat 1111 facing the clamping space 1115. Thus, when the clamping member 1113 and the connecting seat 1111 clamp the optical fiber 200, the torque sensor can directly detect the torsional force applied to the optical fiber 200. Of course, the torque measurement component can also measure the torsional force applied to the optical fiber 200 using other methods, as long as the torsional force applied to the optical fiber 200 can be accurately measured.

[0070] In some embodiments, as shown in Figures 1 to 3, the optical fiber etching device 100 also includes a positioning member 112, which is arranged between the two clamping parts 111 of the clamping assembly 110 and abuts against the portion of the optical fiber 200 located between the two clamping parts 111 to position the portion of the optical fiber 200 located between the two clamping parts 111, so that the portion of the optical fiber 200 located between the two clamping parts 111 remains in a straighter state, thereby further improving the etching accuracy of the optical fiber 200 by the optical fiber etching device 100.

[0071] The positioning member 112 includes a positioning groove 1121 extending along the first direction X and penetrating the positioning member 112. The positioning groove 1121 is used to accommodate the optical fiber 200, and the inner surface of the positioning groove 1121 is used to abut against the outer peripheral surface of the optical fiber 200 to position the optical fiber 200 and keep the optical fiber 200 straight. This prevents the optical fiber 200 from being deformed or completely damaged due to vibration during the laser etching process, thereby affecting the etching accuracy of the optical fiber 200.

[0072] In some embodiments, as shown in Figures 2 and 3 , a suction hole 1122 is defined within the inner surface of the positioning groove 1121 of the positioning member 112. This suction hole 1122 communicates with an air suction component (not shown). When the optical fiber 200 is placed within the positioning groove 1121 of the positioning member 112, the air suction component applies negative pressure to the suction hole 1122, causing the suction hole 1122 to adsorb the optical fiber 200 to the inner surface of the positioning groove 1121. This further enhances the positioning efficiency of the positioning groove 1121 of the positioning member 112 for the optical fiber 200, resulting in higher precision in the processing of the optical fiber 200.

[0073] There are multiple adsorption holes 1122 , and the multiple adsorption holes 1122 are sequentially spaced apart along the first direction X to further improve the adsorption effect on the optical fiber 200 .

[0074] Specifically, as shown in Figure 3, the positioning member 112 is provided with a cavity 1123 extending along the first direction X. The first ends of the plurality of suction holes 1122 are connected to the positioning groove 1121, and the other ends of the plurality of suction holes 1122 are connected to the cavity 1123. A connector 1124 is provided on the outer surface of the positioning member 112, which is connected to the cavity 1123. The connector 1124 is used to connect to the suction component, thereby connecting the plurality of suction holes 1122 to the suction component. The connector 1124 protrudes from the surface of the positioning member 112 on one side along the first direction X.

[0075] In some embodiments, the optical fiber etching apparatus 100 further includes an air pressure sensor (not shown), which is in communication with the adsorption hole 1122 to detect the air pressure within the adsorption hole 1122. It is understood that after the optical fiber 200 is placed within the positioning groove 1121 of the positioning member 112, the air pressure sensor detects the air pressure within the adsorption hole 1122 to confirm whether the adsorption hole 1122 has adsorbed the optical fiber 200 within the positioning groove 1121 of the positioning member 112. Furthermore, during the process of etching the optical fiber 200 with a laser, by detecting the air pressure within the adsorption hole 1122, it is possible to determine whether the optical fiber 200 has been deformed.

[0076] The air pressure sensor can be connected to the connector 1124 on the positioning member 112 to detect the air pressure in the cavity to indirectly detect the air pressure in the adsorption hole 1122. Alternatively, the air pressure sensor can be set in the cavity to directly detect the air pressure in the cavity, thereby indirectly detecting the air pressure in the adsorption hole 1122.

[0077] In some embodiments, the positioning member 112 is made of metal. The laser includes a carbon dioxide laser. Since metal has a very low absorption rate for laser light generated by a carbon dioxide laser, making the positioning member 112 of metal can prevent the positioning member 112 from absorbing excessive laser light when etching the optical fiber 200, thereby causing the positioning member 112 to heat up or even be damaged.

[0078] In some embodiments, the laser can be positioned opposite the opening of the positioning groove 1121. Alternatively, the laser can be positioned on one side of the positioning member 112.
