[0054] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0057] 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, and the coupling position needs to be precisely adjusted in all directions. The traditional coupling method is to manually intervene to adjust the collimating lens, which is difficult and the quality of the finished product is uneven. Therefore, how to achieve automatic fiber coupling, reduce the difficulty of manual technology, and achieve high-quality automated coupling production has become an urgent problem to be solved.

[0058] The utility model proposes a fiber coupling device 100 for solving the above problems. Figures 1 to 10 .

[0059] See also Figure 1 to Figure 2In one embodiment of the utility model, the material storage station 12 is arranged on the same side of the coupling station 11. Specifically, the material storage component on the material storage station 12 includes a stacking structure 13 of an unprocessed coupling material tray 15 and a stacking structure 13 of a processed coupling material tray 15. The above two stacking structures 13 are arranged on the same side of the coupling station 11. When the conveying component 8 transports the coupled coupling material tray 15 to the corresponding stacking structure 13 for unloading, it can move a small distance at the current position and grab and load the unprocessed coupling material tray 15 at the same time. Therefore, the structure of arranging the material storage station 12 on the same side of the coupling station 11 can effectively reduce the movement stroke of the conveying component 8. When the entire device is running at full load, it can also effectively shorten the loading and unloading cycle, thereby improving production efficiency. It should be noted that the coupling tray 15 is fixed with materials for coupling processing, specifically including optical fiber, stripper and collimator, wherein the tail end of the optical fiber is inserted in the stripper, and the collimator and the stripper are fixed on the coupling tray 15 along the length direction of the coupling tray 15, and the assembly of the above materials is pre-installed before specific processing. The specific setting of the coupling structure includes positioning tooling, bare fiber adapter 9 and adjustment part 3, and the above components are all installed at the coupling station 11. Among them, the positioning fixture is used to fix the coupling tray 15 to facilitate the positioning and placement of materials during the coupling operation. After the coupling tray 15 is fixed on the positioning fixture, one end of the optical fiber on the coupling tray 15 is fixed by the bare fiber adapter 9, and the light source is output to the optical fiber and the stripper. At the same time, the horizontal and vertical positions of the optical fiber and the stripper are adjusted by the adjustment part 3, so that the light spot output by the optical fiber and the stripper is coupled with the output light spot of the collimator, and then the relevant materials are physically coupled according to the current position relationship, so that the coupling position of the above three materials reaches the optimal state, thereby improving the coupling accuracy and ensuring the output power after the optical fiber coupling.

[0060] Wherein, the positioning fixture includes a positioning structure, and the positioning structure specifically includes a first positioning portion 2 .

[0061] Specifically, Figure 3As shown, when fixing the coupling tray 15, firstly, the coupling tray 15 is placed on the receiving plate 22 through the conveying assembly 8, and then the output end of the second cylinder 224 retracts and drives the T-shaped mounting plate 225 to move, thereby fixing the length direction of the coupling tray 15 between the second limit block 222 and the multiple bearings 226 on the T-shaped mounting plate 225, and then the first cylinder 223 starts to work, and one end thereof pushes the coupling tray 15 to slide on the receiving plate 22, and finally the coupling tray 15 is fixed between the first cylinder 223 and the first limit block 221. In this process, the width end of the coupling tray 15 drives the multiple bearings 226 to rotate during the sliding process, thereby effectively reducing the friction force of the coupling tray 15 during the movement. By fixing the coupling material tray 15 on the receiving plate 22 in the above manner, the positioning effect of the coupling material tray 15 in the X direction and the Y direction can be effectively guaranteed, and the material on the coupling material tray 15 also has a relatively fixed initial position coordinate, which is convenient for the subsequent removal of related materials. In this embodiment, the second cylinder 224 is installed under the receiving plate 22, which can effectively reduce the space occupied by the second cylinder 224 along the length direction of the receiving plate 22, making the entire first positioning part 2 more compact in structure.

[0062] like Figure 4 and Figure 5As shown, the bare fiber adapter 9 mainly includes a third cylinder 92 and a clamping member, wherein the third cylinder 92 is installed on the second mounting frame 91, and a mounting portion 93 is provided on the output end of the third cylinder 92, and the mounting portion 93 has a certain installation adjustment capability. Specifically, the mounting portion 93 includes a first slide 931 and a second slide 932, wherein the first slide 931 is arranged horizontally and is connected to the output end of the third cylinder 92 by bolts, and has the ability to adjust in the horizontal direction after the bolts are removed, and the second slide 932 is arranged in a vertical direction, and its downward end is connected to the first slide 931, and the second slide 932 is also detachably connected to the first slide 931 by bolts, and in the specific use process, the fixed position of the second slide 932 on the first slide 931 can be adjusted, and then the second slide 932 is fixed to the current position of the first slide 931 by bolts. The position of the clamping member on the second slide 932 is adjusted in the above manner. Specifically, when the entire structure is working, the fourth cylinder 94 first moves downward, and its output end presses down one end of the pressure head 95, the first spring 96 is compressed, and at the same time, the other end of the pressure head 95 is separated from the optical fiber guide plate 97. At this time, the third cylinder 92 moves, driving the clamping member to move toward the end of the optical fiber on the coupling tray 15 that is exposed, and inserts the end of the optical fiber into the bare fiber adapter 98 after passing through the pressure head 95 and the optical fiber guide plate 97. Then the third cylinder 92 moves upward, and the first spring 96 is reset to drive the pressure head 95 to press down and fix the end of the optical fiber. In this process, a flexible material is provided on the end surface of the optical fiber guide plate 97 and the pressure head 95 that are in contact to protect the end of the optical fiber. After the end of the optical fiber is fixed, a light source can be introduced into the optical fiber and the stripper through the bare fiber adapter 98.

[0063] After one end of the pipeline is inserted into the bare fiber adapter 98, the bare fiber adapter 98 can output light. At this time, to determine the best coupling angle position between the materials on the coupling material 15 plate, the relative positions between the materials need to be adjusted. Specifically, Figure 1 and Figure 3As shown, the three-axis adjustment member 31 located at the bottom is installed on the base 1, and has a movement range in the three directions of X, Y, and Z, so it has the ability to adjust the position in these three directions. When working, the first suction nozzle 331 and the first clamping claw 332 respectively take out the stripper and the optical fiber on the coupling material tray 15, and move them to the position directly above the coupling material tray 15. The first rotating member 321 can drive the first suction nozzle 331 and the first clamping claw 332 to rotate simultaneously through the first mounting seat 323, so as to adjust their positions in the side view direction. At the same time, the second rotating member 322 can drive the first suction nozzle 331 to rotate, so as to adjust the relative position of the stripper and the optical fiber in the top view direction. After the position of the optical fiber and the stripper is pre-coupled through the above structure, the optical fiber and the stripper are transplanted to the specified position in the coupling groove inside the collimator through the corresponding three-axis adjustment member 31. Specifically, the three-axis adjustment member 31 is installed on the third mounting frame 14, and the three-axis adjustment member 31 includes a first linear guide rail 311, and the first linear guide rail 311 is provided with a first sliding mounting frame 312, and the first sliding mounting frame 312 is connected to the first linear motor 313 on the first linear guide rail 311, and the first sliding mounting frame 312 is provided with a first adjusting cylinder 314 which is horizontally installed and perpendicular to the first linear motor 313, and the output end of the first adjusting cylinder 314 is provided with a second adjusting cylinder 315 which is vertically installed, and the first rotating member 321 is connected to the second adjusting cylinder 315. In actual use, the linear motor, the first adjusting cylinder 314 and the second adjusting cylinder 315 cooperate with each other to move, so that the optical fiber and the stripper have movement effects in three directions of X, Y and Z, so that their positions can be adjusted in real time according to actual conditions.

[0064] When judging the positions of the optical fiber, the stripper and the collimator, a corresponding visual analysis structure is required, so in this embodiment, the adjusting member in the previous embodiment is provided with a corresponding visual sensor component and a light spot detection structure 43. The visual sensor component includes a lateral detection component 41 and a vertical detection component 42, which are both installed on the base 1 and are used to detect the vertical and horizontal positions of the optical fiber and the stripper, respectively. Specifically, the lateral detection component 41 includes a first camera 412 and a reflector 413. A camera mounting frame 414 is provided on the base 1. The first camera 412 is installed on the camera mounting frame 414. A first lens 415 is provided on the end of the first camera 412. The reflector 413 is arranged corresponding to the first lens 415. It should be noted that in order to make the structure of the entire device more compact and reduce its overall occupied area, the first camera 412 mounting frame is arranged on one side of the material receiving plate 22 along the length direction of the material receiving plate 22. At this time, the first camera 412 is located on one side of the length direction of the coupling material tray 15 on the material receiving plate 22. When detecting the side view position of the optical fiber and the stripper, it is necessary to arrange the reflector 413 as follows Figure 7The tilt angle shown can guide the parallel light in the length direction of the coupling material tray 15 to its width direction. At the same time, a first backlight source 416 is provided on the first mounting seat 323 corresponding to the reflected light from the reflector 413. The lateral detection component 41 formed by the first camera 412, the first lens 415, the reflector 413 and the first backlight source 416 can monitor and feedback the side relative positions of the optical fiber and the stripper in real time. The vertical detection member 42 is arranged above the material receiving plate 22, and includes a second camera 421 and a second backlight source 422. The second camera 421 is arranged vertically and a second lens 423 is arranged on its output end. The second backlight source 422 is mounted on the first mounting frame 21 corresponding to the second lens 423. The vertical detection member 42 formed by the second camera 421, the second lens 423 and the second backlight source 422 can obtain the relative relationship between the optical fiber and the stripper in the top view direction, and cooperate with the adjustment member in the above embodiment to adjust the coupling position of the optical fiber and the stripper in real time. In addition, the light spot detection structure 43 includes a light spot analyzer 431 and a detection adjustment member 432. Specifically, a third lens is arranged on the output end of the light spot analyzer 431, and the end of the third lens is arranged corresponding to the end of the collimator on the coupling material tray 15. In actual use, the detection adjustment member 432 has a three-axis adjustment capability and can adjust the end position of the light spot analyzer 431 in real time. In specific operation, the bare fiber adapter 98 tooling is used to output light sources to the optical fiber in the collimator and the stripper, and the spot shape parameters of the output end of the collimator are obtained through the spot analyzer 431. The position of the spot analyzer 431 is continuously adjusted through the detection adjustment member 432, so that the output end spot parameters meet the preset spot image shape parameters, and then the spot angle parameters can be determined according to the extracted spot image, and the spot angle coupling is completed. It can be imagined that the structure of the detection adjustment member 432 can be set with reference to the three-axis adjustment member 31 in the above embodiment.

[0065] After the above-mentioned spot angle coupling is completed, it is necessary to first glue and solidify the stripper and the collimator through the glue dispensing component 5. Specifically, mainly as follows Figure 8 and Fig. 9As shown, the horizontal adjustment member 511 includes a second linear motor 5111 and a first glue dispensing cylinder 5112, wherein the second linear motor 5111 is installed on the third mounting frame 14, and the first glue dispensing cylinder 5112 is perpendicular to the movement direction of the second linear motor 5111 and horizontally installed on the slider of the second linear motor 5111, thereby forming a horizontal plane adjustment structure, and a vertical adjustment member 512 is vertically installed on the output end of the first glue dispensing cylinder 5112, and the second linear motor 5111, the first glue dispensing cylinder 5112 and the vertical adjustment member 512 work together to cooperate with the vertical detection member 42 to couple the material tray. 15, the output end of the glue dispensing device 522 can be adjusted to the top of the corresponding glue dispensing position, and then the vertical driving element 521 on the mounting plate 513 drives the glue dispensing device 522 downward to complete the glue dispensing operation. In addition, in order to speed up the curing of the glue, during this process, the glue dispensing device 522 is first moved to the designated area of ​​the collimator for glue dispensing. After the glue dispensing action is completed, the stripper is moved to the position where the coupling is completed before through the above-mentioned three-axis adjustment member 31 and the rotating adjustment member 32. At this time, there is glue attached between the stripper and the collimator. After the glue is cured, it can be ensured that the stripper will not loosen in the collimator.

[0066] After the stripper is coupled, it is necessary to adjust the position of the optical fiber in the collimator through the optical fiber positioning member 7, and then fix the optical fiber by glue. The glue fixing operation of this process is performed on the second positioning part 6. The structure of the second positioning part 6 is the same as that of the first positioning part 2, and the above two positioning parts are arranged adjacent to each other. At the same time, in order to make the coupling material tray 15 on the receiving plate 22, the corresponding fixing cylinder can automatically clamp and fix the coupling material tray 15. Figure 3 As shown, sensors are provided on the receiving plate 22 .

[0067] Specifically, Figure 3 , Figure 8 and Fig.10As shown, the conveying assembly 8 moves the coupled material tray 15 after the stripper is coupled to the second positioning part 6. At this time, after the sensor on the material receiving plate 22 in the second positioning part 6 detects the material, the corresponding cylinder parts clamp and position the coupled material tray 15 in the X and Y directions respectively. The first air claw part 753 clamps the optical fiber at the tail of the collimator, and then the horizontal displacement part 71 drives the vertical frame 72 to move along the extension of the optical fiber to straighten the optical fiber to ensure that the optical fiber is completely placed in the optical fiber groove of the collimator. Then the fifth cylinder 73 cooperates with the sixth cylinder 751 to drive the pressing head 752 to press down and fix the optical fiber placed in the optical fiber groove, and then moves to the designated area of ​​the collimator through the glue dispensing device 522 in the above embodiment to dispense glue. After the glue is cured, it can be ensured that the optical fiber in the optical fiber groove of the collimator will not loosen.
