[0038] Semiconductor lasers usually have fiber collimators, and the performance of fiber collimators plays a decisive role in the performance of the entire laser. Fiber collimators can collimate the divergent light beam emitted from the end face of the optical fiber into a parallel light beam through a self-focusing lens, or couple the parallel light beam into the optical fiber through a self-focusing lens. In order to ensure the output power, the fiber collimator requires a high coupling accuracy. In the traditional coupling process, most of the material loading and adjustment are required manually. Specifically, the multiple materials required in the coupling process are loaded and fixed separately, and then their positions are adjusted during coupling for production operations. This method not only has a more complicated process, but also is difficult to meet the efficient production needs of automatic optical fiber coupling.

[0039] The utility model proposes an optical fiber coupling tray 100 to solve the above problems. Please refer to Figures 1 to 5 .

[0040] See also Figure 1 to Figure 2 In one embodiment of the utility model, the materials needed in the optical fiber coupling process are fixed on the same base 1. Specifically, the base 1 is provided with a first fixing structure, a second fixing structure and a third fixing structure corresponding to the stripper, the collimator and the optical fiber to fix and install them. In the specific use process, the materials for coupling production are pre-installed on the corresponding fixing structures before production to form prefabricated assembly parts. In the process of automated production with the help of machines, it is only necessary to set the corresponding loading and unloading structures of the base 1 on the production machine, so as to realize the loading and unloading operations of multiple production materials through one loading structure, which can contribute to the compact and miniaturized design of the production machine to a certain extent. In addition, the production materials required for a coupling operation are fixed on the base 1 at one time. In a coupling production process, the process of supplementing and fixing the materials again is avoided, which is conducive to simplifying the production process and improving production efficiency.

[0041] like Figure 1 and Figure 4 As shown, in the first fixing structure, when fixing the stripper, first manually pull the first pressing head 21 to rotate so that the end of the first pressing head 21 located on the outside of the base 1 is fully separated from the base 1, and then place the stripper on the base 1 along the length direction of the base 1. After the placement is completed, the first driving member drives the first pressing head 21 to rotate around the axis extending along the length direction of the base 1, so that the upward end of the pressing head is pressed down and fixed to the stripper.

[0042] In order to make the overall structure of the first fixing structure simpler, the first driving member is configured as a torsion spring (not shown in the figure). Figure 1 and Figure 4 As shown, it can be imagined that in order to increase the fixing effect, a corresponding boss structure can be set on the base 1, and a placement groove corresponding to the arc-shaped side wall of the stripper is provided on the first pressure head 21 and the boss structure, thereby increasing the limiting and fixing effect of the stripper.

[0043] When fixing the collimator, Figure 2 and Figure 5As shown, first, the collimator is inserted inward from one end of the fixing groove 32 away from the third fixing structure. During this process, the collimator contacts the arc-shaped surfaces of the ends of the plurality of plungers 31 in turn, and applies force to them, so that the plurality of elastic members (not shown in the figure) are in a compressed state. After the fixation is completed, the plurality of elastic members respectively apply stable pressure to one end of the collimator through the plurality of plungers 31, so that the collimator is fixed in the fixing groove 32. When in use, one end of the collimator emits light from one end of the fixing groove 32, so as to meet the subsequent calibration operation. Among them, it can be imagined that in order to further reduce the friction between the collimator and the ends of the plurality of plungers 31 when the collimator is inserted into the fixing groove 32, a ball bearing can be provided on one end of the plurality of plungers 31. During the insertion of the collimator, the ball bearing rolls on one end of the plunger 31, thereby converting the sliding friction into rolling friction, and further protecting the collimator. The elastic member is preferably set as a spring.

[0044] In the design of the base 1, considering that the base 1 needs to meet the requirements of automatic loading to adapt to the production of the automatic machine, and in order to minimize the horizontal occupied area of ​​the machine, it is best to place multiple bases 1 in a stacked form. Figure 2 and Figure 3 As shown, in this embodiment, in order to enable each of the bases 1 to maintain a good positioning state when stacked and to perform fool-proofing, a plurality of support portions 15 are provided on an end face of the base 1 corresponding to the plurality of fixed structures, and the plurality of support portions 15 have a certain vertical height. When two bases 1 are stacked, a certain vertical distance can be maintained between the two adjacent bases 1, thereby avoiding affecting the materials fixed on the base 1, and when stacked, the positioning protrusion 16 cooperates with the positioning hole 17, thereby positioning the two superimposed bases 1, so that the plurality of bases 1 can be more stable after being stacked.

[0045] In order to further achieve the lightweight of the base 1, a first sunken portion 11 is provided at the end of the base 1 away from the first pressure head 21, and a fiber optic limiting groove 14 is provided on the base 1 along the extension direction of its length to connect the sunken portion with the outside of the base 1. During specific use, one end of the optical fiber is inserted into the fiber optic limiting groove 14 to ensure that the optical fiber is in a horizontal state as much as possible.

[0046] When fixing the optical fiber, the excess length of the optical fiber is coiled, and the pressing plate 42 at the first sinking part 11 is rotated to press down the coiled optical fiber, and the flexible contact of the flexible pressing block 43 protects the pipeline and prevents it from tilting. Specifically, multiple coiling fixtures can be provided to increase the fixing effect of the optical fiber coiling position. In addition, one end of the optical fiber extends outward from the optical fiber limiting groove 14, and a fixing part fixing is provided at the installation groove 13 to limit the end of the optical fiber. Specifically, the pressing part 45 is turned over so that the pressing part 45 is attached to the end surface of the base 1, thereby preventing the optical fiber end from tilting. It can be imagined that the pressing plate 42 and the pressing part 45 in this embodiment are both rotatably installed, and they must have a certain downward force, so the pressing plate 42 and the pressing part 45 have a certain weight, or a certain damping effect is provided at the position where they are rotatably installed.

[0047] In the subsequent coupling process, the exposed end of the optical fiber needs to have a certain length, so a fixed-length plate 5 is installed at one end of the base 1. During the pre-installation of the optical fiber, the fixed-length plate 5 can be used to determine the length of the exposed end of the optical fiber.

[0048] In addition, a plurality of optical fiber limiting rods 46 are provided on the base 1, and the plurality of pipeline limiting rods are arranged between the placement groove and the optical fiber limiting groove 14 along the length direction of the base 1. When fixing, the tail of the optical fiber can be limited by the plurality of optical fiber limiting rods 46, thereby preventing the tail of the optical fiber from warping up, and the tail of the optical fiber can also maintain a good straight state, which is beneficial to the subsequent coupling operation.

[0049] In order to ensure that the two ends of the optical fiber are kept at the same vertical height as much as possible after being fixed, a second sunken portion 12 is provided at one end of the base 1, and the corresponding first pressing head 21 is installed at the second sunken portion 12. After the stripper is fixedly installed, the tail end of the optical fiber can correspond to the end of the stripper.

[0050] In addition, in order to further reduce the weight of the base 1 , a plurality of hollow portions 18 are provided on the base 1 , thereby facilitating the need for lightweighting the base 1 .

[0051] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
