[0069] Reference Figures 1 to 17 As shown in the drawings, the method for mounting the optical fiber array isolator according to an embodiment of the present application is applied to a mounting device having a microscope platform 400 and a clamping assembly, and the clamping assembly has a clamping station 511. The method for mounting the optical fiber array isolator comprises the following steps:

[0070] In step S100, the optical fiber array 100 is fixed to the clamping station 511 of the clamping assembly, and the microscope platform 400 is controlled to obtain a marked image of the mounting end face 120 of the optical fiber array 100 located in the clamping station 511, and the marked image is magnified by a predetermined multiple;

[0071] Step S200: According to the marked image, mark the calibration center 370 corresponding to the fiber center 110 of the fiber array 100 in the microscope platform 400, and according to the mounting requirements of the isolator 200 relative to the fiber center 110, mark the mounting area of ​​the isolator 200 relative to the calibration center 370 in the microscope platform 400.

[0072] In step S300, align the fiber center 110 with the calibration center 370, mount the isolator 200 on the mounting end face 120, and place the isolator 200 into the mounting area to achieve alignment between the isolator 200 and the mounting area.

[0073] Reference Figure 1 , Figure 10 and Figure 11 As shown, in step S100, the user can fix the fiber array 100 onto the clamping station 511 of the clamping assembly to achieve positioning of the fiber array 100 at the clamping station 511. The microscope on the microscope platform 400 mounted above the clamping assembly can acquire a marking image of the mounting end face 120 of the fiber array 100 located at the clamping station 511. By attaching multiple end faces of the fiber array 100 to the various walls of the clamping station 511, the positioning of the fiber array 100 and the clamping station 511 is achieved, ensuring the positioning accuracy of the fiber array 100 and improving the accuracy of the images acquired by the microscope platform 400. The marking image is magnified by a preset magnification to improve the accuracy of subsequent marking.

[0074] Reference Figure 1 , Figure 10 and Figure 11 As shown, in step S200, the method for mounting isolators in the fiber array marks the calibration center 370 corresponding to the fiber center 110 of the fiber array 100 on the microscope platform 400 according to the marking image. Based on the mounting requirements of the isolator 200 relative to the fiber center 110, i.e., based on the product requirements of the isolator 200 relative to the fiber center 110, the mounting area of ​​the isolator 200 relative to the calibration center 370 after being magnified by a preset factor is marked on the microscope platform 400. The marking image is magnified by a preset factor by the microscope platform 400 to improve the accuracy of the marking. The relative positional relationship between the existing calibration center 370 and the mounting area can guide the subsequent mounting process.

[0075] Reference Figure 1 , Figure 10 and Figure 11As shown in step S300, in the subsequent mounting process, the user needs to align the magnified fiber center 110 of the fiber array 100 with the calibration center 370, and then mount the isolator 200 on the mounting end face 120, and adjust the position of the isolator 200 according to the mounting area, so that the isolator 200 is placed in the mounting area, so that the isolator 200 is aligned with the mounting area, thereby improving the mounting accuracy of the isolator 200 and the fiber center 110.

[0076] Referring to Figure 1 , Figure 15 and Figure 16 As shown, compared with the traditional mounting process, the fiber array mounting isolator method provided by the embodiment of the application is magnified and marked by the obtained mounting actual data to obtain accurate guidance data, and the subsequent mounting process is assisted according to the guidance data, thereby improving the mounting precision of the isolator 200 and the fiber array 100. The relative position relationship between the mounting area and the calibration center 370 is used to assist in mounting the isolator 200 and the fiber array 100, which helps to improve the mounting efficiency of the isolator 200 and the fiber array 100.

[0077] Referring to Figure 14 , Figure 15 and Figure 16 As shown, it can be understood that the fiber array 100 has a plurality of fiber centers 110, and the fiber array mounting isolator method can be used to mount the fiber array 100 and the array isolator 200, that is, a plurality of isolators 200 are mounted on one fiber array 100 respectively with a plurality of fiber centers 110. Specifically, the isolator 200 is mounted one by one with the fiber center 110.

[0078] Referring to Figure 10 , Figure 11 and Figure 13 As shown, specifically, the microscope platform 400 is a CCD microscope platform 400, which is an imaging system combining an optical microscope and a CCD (Charge Coupled Device) camera, mainly used for high-precision observation, recording and analysis of microstructure. The CCD microscope platform 400 has a line drawing function, that is, a function of superimposing virtual lines (such as cross lines, straight lines, grids, etc.) on the image.

[0079] Referring to Figure 2 , Figure 6 and Figure 17 As shown, in step S200, the fiber array mounting isolator method marks the calibration center 370 corresponding to the fiber center 110 of the fiber array 100 in the microscope platform 400 according to the marked image, comprising the following steps:

[0080] Step S210, draw a first marking line 310 at each fiber center 110 along the arrangement direction of the plurality of fiber centers 110;

[0081] Step S220, draw a second marking line 320 at each fiber center 110 perpendicular to the first marking line 310, and the intersection of the first marking line 310 and the second marking line 320 is the calibration center 370.

[0082] Referring to Figure 2 , Figure 6 and Figure 17 , in steps S210 and S220, the method of the fiber array mounting isolator can draw a first marking line 310 and a second marking line 320 perpendicular to the first marking line 310 on the fiber center 110 in the microscope platform 400 according to the marking image, and the intersection of the first marking line 310 and the second marking line 320 is the calibration center 370. That is, the method of the fiber array mounting isolator can draw a cross line on the fiber center 110 through the microscope platform 400, thereby realizing the marking of the fiber center 110. The following is an example of taking the direction of the first marking line 310 as the X-axis direction (left-right direction), the direction of the second marking line 320 as the Y-axis direction (front-back direction), and the up-down direction as the Z-axis direction.

[0083] Referring to Figure 2 , Figure 6 and Figure 17 , the method of the fiber array mounting isolator can be used to realize the precise integration of the multi-channel optical isolator 200 and the fiber array 100, that is, to realize the mounting of multiple isolators 200 and multiple fiber centers 110 on the same fiber array 100, so as to promote the development of 400G, 800G high-speed optical communication modules.

[0084] Referring to Figure 3 , Figure 7 and Figure 17 , it can be understood that, taking the mounting of the lower end of the isolator 200 and the mounting end face 120 of the fiber array 100 as an example, the upper end face of the isolator 200 has a first boundary 210 and a second boundary 220 arranged at intervals along the second marking line 320, that is, the first boundary 210 and the second boundary 220 are spaced apart along the second marking line 320, and the first boundary 210 and the second boundary 220 are both parallel to the first marking line 310.

[0085] Referring to Figure 3 , Figure 7 and Figure 17 , in step S200, the method of the fiber array mounting isolator marks the mounting area of the isolator 200 relative to the calibration center 370 in the microscope platform 400 according to the mounting requirements of the isolator 200 relative to the fiber center 110, including the following steps:

[0086] Step S230, calculating the first distance between the first boundary 210 and the calibration center 370 and the second distance between the second boundary 220 and the calibration center 370 according to the mounting requirement;

[0087] Step S240, drawing a first demarcation line 330 spaced apart from the first mark line 310 by the first distance and parallel to the first mark line 310 and a second demarcation line 340 spaced apart from the first mark line 310 by the second distance and parallel to the first mark line 310 on the microscope platform 400, the first demarcation line 330 and the second demarcation line 340 are both demarcation lines of the mounting area.

[0088] Referring to Figure 3 , Figure 7 and Figure 17 , in step S230, the first distance between the first boundary 210 and the calibration center 370 and the second distance between the second boundary 220 and the calibration center 370 are calculated according to the mounting requirement of the isolator 200 and the fiber center 110.

[0089] Referring to Figure 3 , Figure 7 and Figure 17 , taking the mark image obtained by the microscope platform 400 as an example, the preset magnification is 100 times. As in the actual product requirement, the distance between the first boundary 210 of the isolator 200 and the fiber center 110 is 0.3mm, then the distance between the first boundary 210 of the isolator 200 and the calibration center 370 in the mark image should be 30mm, that is, the first distance is 30mm. The calculation method of the second distance of the isolator 200 is the same as that of the first distance, which will not be repeated here.

[0090] Referring to Figure 3 , Figure 7 and Figure 17 , in step S240, the method of mounting the fiber array isolator can draw a first demarcation line 330 spaced apart from the first mark line 310 by the first distance and parallel to the first mark line 310 and a second demarcation line 340 spaced apart from the first mark line 310 by the second distance and parallel to the first mark line 310 on the microscope platform 400 according to the known first distance and second distance.

[0091] Referring to Figure 3 , Figure 7 and Figure 17As shown, the first boundary line 330 and the second boundary line 340 are both boundary lines of the mounting area. The method of mounting the isolator in this fiber array can be achieved by drawing the first boundary line 330 and the second boundary line 340 on the microscope platform 400, thereby guiding the mounting of the isolator 200 with the fiber center 110. The user can adjust the position of the isolator 200 so that the first boundary 210 and the second boundary 220 of the isolator 200 are aligned with the first boundary line 330 and the second boundary line 340 respectively, thereby improving the mounting accuracy of the isolator 200 with the fiber center 110.

[0092] Reference Figure 4 , Figure 8 and Figure 17 As shown, it can be understood that, taking the mounting of the lower end of the isolator 200 to the mounting end face 120 of the fiber array 100 as an example, the upper end face of the isolator 200 has a third boundary 230 and a fourth boundary 240 arranged at intervals along the first marking line 310, that is, the third boundary 230 and the fourth boundary 240 are spaced apart along the first marking line 310, and both the third boundary 230 and the fourth boundary 240 are parallel to the second marking line 320.

[0093] Reference Figure 3 , Figure 8 and Figure 17 As shown, the method for mounting isolators on a fiber optic array includes the following steps in step S200: Based on the mounting requirements of the isolator 200 relative to the fiber center 110, the mounting area of ​​the isolator 200 relative to the calibration center 370 is marked on the microscope platform 400.

[0094] Step S250: Calculate the third distance between the third boundary 230 and the calibration center 370, and the fourth distance between the fourth boundary 240 and the calibration center 370, according to the mounting requirements.

[0095] In step S260, a third dividing line 350, which is parallel to the second marking line 320 and spaced a third distance apart, and a fourth dividing line 360, which is parallel to the second marking line 320 and spaced a fourth distance apart, are drawn on the microscope platform 400. Both the third dividing line 350 and the fourth dividing line 360 ​​are dividing lines of the mounting area.

[0096] Reference Figure 3 , Figure 8 and Figure 17 As shown, in step S250, the first distance between the third boundary 230 and the calibration center 370, and the second distance between the fourth boundary 240 and the calibration center 370 are calculated according to the mounting requirements of the isolator 200 and the fiber center 110.

[0097] Reference Figure 3 , Figure 8 and Figure 17As shown in the marking image acquired by the microscope platform 400, the preset magnification is 100 times. As required in the actual product, the width of the isolator 200 is 0.5 mm, so the width of the isolator 200 in the marking image should be 50 mm, and the third distance and the fourth distance are both 25 mm.

[0098] Referring to Figure 3 , Figure 8 and Figure 17 , in step S260, the method of mounting the isolator to the fiber array can draw a third boundary line 350 spaced apart from the second marking line 320 by the third distance and parallel to the second marking line 320, and a fourth boundary line 360 spaced apart from the second marking line 320 by the fourth distance and parallel to the second marking line 320 on the microscope platform 400 according to the third distance and the fourth distance.

[0099] Referring to Figure 3 , Figure 8 and Figure 17 , if the X-axis coordinate of the fiber center 110 is 300, the third distance and the fourth distance are both 25 mm, the X-axis coordinate of the third boundary line 350 is 275, and the X-axis coordinate of the fourth boundary line 360 is 325.

[0100] Referring to Figure 3 , Figure 8 and Figure 17 , the third boundary line 350 and the fourth boundary line 360 are both boundary lines of the mounting area, and the method of mounting the isolator to the fiber array can guide the mounting of the isolator 200 to the fiber center 110 by drawing the third boundary line 350 and the fourth boundary line 360 on the microscope platform 400, so that the user can adjust the position of the isolator 200 to align the third boundary 230 and the fourth boundary 240 of the isolator 200 with the third boundary line 350 and the fourth boundary line 360 respectively, thereby improving the mounting accuracy of the isolator 200 to the fiber center 110.

[0101] Referring to Figure 3 , Figure 8 and Figure 17 , the first boundary line 330, the second boundary line 340, the third boundary line 350 and the fourth boundary line 360 together define the mounting area, so that guidance data about the mounting area relative to the target calibration center 370 is obtained, and the method of mounting the isolator to the fiber array can guide the mounting of the isolator 200 to the fiber array 100 through the guidance data, thereby improving the mounting accuracy of the isolator 200 to the fiber array 100.

[0102] Referring to Figure 4 , Figure 10 and Figure 13As shown, it can be understood that the method of the optical fiber array mounting isolator, in step S300, aligning the optical fiber center 110 with the calibration center 370, comprises the following steps:

[0103] Step S310, when mounting a plurality of optical fiber arrays 100 in sequence, fixing the optical fiber array 100 to be mounted on the clamping station 511;

[0104] Step S320, adjusting the relative position of the clamping assembly and the microscope platform 400 to align the optical fiber center 110 with the calibration center 370.

[0105] Referring to Figure 4 , Figure 10 and Figure 12 , the method of the optical fiber array mounting isolator amplifies and marks the actual mounting data obtained to obtain accurate guidance data, and assists the mounting process of this time and subsequent times according to the guidance data.

[0106] Referring to Figure 4 , Figure 10 and Figure 11 , it should be noted that when the isolator 200 is mounted to the mounting surface of the optical fiber array 100, the height of the end face of the isolator 200 is not consistent with the height of the mounting end face 120 of the optical fiber array 100. The user can adjust the focal length of the microscope platform 400 to ensure the clarity of the calibration image.

[0107] Referring to Figure 4 , Figure 10 and Figure 13 , in steps S310 and S320, when mounting a plurality of optical fiber arrays 100, the optical fiber array 100 to be mounted can be fixed on the clamping station 511. Considering that the relative position of the clamping assembly and the microscope platform 400 may deviate, therefore, before mounting, the method of the optical fiber array mounting isolator can adjust the relative position of the clamping assembly and the microscope platform 400, so that the optical fiber center 110 is aligned with the calibration center 370, so that the mounting area can be used to assist the mounting of the isolator 200.

[0108] Referring to Figure 5 , Figure 14 and Figure 15 , it can be understood that the clamping assembly includes a clamping seat 510 and a limiting plate 550, the clamping seat 510 has a clamping station 511; the limiting plate 550 is used to assist the positioning of the isolator 200 and the optical fiber center 110.

[0109] Referring to Figure 5 , Figure 14 and Figure 15As shown, specifically, the method of mounting the isolator to the fiber array in step S300 includes the following steps:

[0110] In step S330, glue is applied to the upper end of the clamping seat 510;

[0111] In step S340, the limiting plate 550 is mounted at the glued position of the upper end of the clamping seat 510, and the position of the limiting plate 550 is adjusted so that the edge of the limiting plate 550 close to the fiber center 110 coincides with the first boundary line 330.

[0112] In step S350, the isolator 200 is mounted to the mounting end face 120, and the position of the isolator 200 is adjusted so that the first boundary 210 of the isolator 200 abuts against the edge of the limiting plate 550 close to the fiber center 110.

[0113] Referring to Figure 5 , Figure 14 and Figure 15 , after the fiber array 100 to be mounted is fixed to the clamping station 511 in steps S330 and S340, the method of mounting the isolator to the fiber array realizes the positioning of the fiber array 100 by the fitting of the multiple end faces of the fiber array 100 to the multiple wall faces of the clamping station 511, then the glue is applied to the upper end of the clamping seat 510, then the limiting plate 550 is mounted at the glued position of the upper end of the clamping seat 510, and the position of the limiting plate 550 is adjusted so that the edge of the limiting plate 550 close to the fiber center 110 coincides with the first boundary line 330.

[0114] Referring to Figure 5 , Figure 14 and Figure 15 , in step S350, when the user mounts the isolator 200, the isolator 200 can be mounted to the mounting end face 120, and the position of the isolator 200 is adjusted so that the first boundary 210 of the isolator 200 abuts against the edge of the limiting plate 550 close to the fiber center 110, that is, the alignment of the first boundary 210 of the isolator 200 and the first boundary line 330 is realized.

[0115] Referring to Figure 5 , Figure 14 and Figure 15 , that is, the method of mounting the isolator to the fiber array can mount the limiting plate 550 at the upper end of the clamping seat 510 according to the first boundary line 330, so that the edge of the limiting plate 550 close to the fiber center 110 coincides with the first boundary line 330, and then the abutment of the isolator 200 and the edge of the limiting plate 550 close to the fiber center 110 is used to assist in realizing the alignment of the first boundary 210 of the isolator 200 and the first boundary line 330.

[0116] The traditional mounting process is limited by the machining precision. When guiding and mounting the isolator 200 through the slot or hole of the plate, although the mounting efficiency can be improved, the mounting precision is relatively low, and it is difficult to meet the mounting requirements of the isolator 200 with small size and high mounting precision.

[0117] Referring to Figure 5 , Figure 14 and Figure 15 , the method for mounting the isolator provided by the embodiment of the application can convert the virtual guidance of the first boundary line 330 into the entity limiting guidance of the limiting plate 550 by gluing and mounting the limiting plate 550. In the subsequent mounting process, only the first boundary 210 of the isolator 200 needs to be abutted against the edge of the limiting plate 550 close to the fiber center 110, so that the alignment of the first boundary 210 of the isolator 200 and the first boundary line 330 can be realized. By gluing and positioning under the assistance of the microscope platform 400, the mounting precision of the limiting plate 550 can be further improved, so as to improve the mounting precision of the isolator 200 and the fiber center 110.

[0118] Referring to Figure 6 , Figure 9 and Figure 15 , it can be understood that some mounting processes use the slot or hole of the plate for guidance to assist in mounting the isolator 200 and the fiber array 100. However, due to the limitation of machining precision, the mounting method using the slot or hole for guidance is difficult to be applied to the isolator 200 with small size (such as 0.5mm in length, width and height) and high mounting precision (±0.05mm).

[0119] Referring to Figure 6 , Figure 9 and Figure 15 , the method for mounting the isolator in the fiber array in step S300 mounts the isolator 200 on the mounting end face 120 and places the isolator 200 in the mounting area, including the following steps:

[0120] Step S360, gluing is performed at the position of the mounting end face 120 corresponding to the fiber center 110, and the isolator 200 is mounted at the gluing position of the mounting end face 120. The position of the isolator 200 is adjusted so that each boundary of the isolator 200 is aligned with each boundary line of the mounting area.

[0121] Step S370, the glue liquid on the mounting end face 120 is accelerated to solidify, so as to fix the relative position of the isolator 200 and the fiber array 100.

[0122] Referring to Figure 6 , Figure 9 and Figure 15As shown in step S360, the user can apply glue on the mounting end face 120 at a position corresponding to the fiber center 110, and mount the isolator 200 on the mounting end face 120 at a position corresponding to the fiber center 110, i.e., mount the isolator 200 on the glued area of the mounting end face 120, and then the user can adjust the position of the isolator 200 on the mounting end face 120 by using auxiliary tools such as tweezers, so that each boundary of the isolator 200 is aligned with each boundary of the mounting area.

[0123] Referring to Figure 6 , Figure 9 and Figure 17 , under the assistance of the limiting plate 550, the user can first abut the first boundary 210 of the isolator 200 against the edge of the limiting plate 550 close to the fiber center 110, so as to align the first boundary 210 of the isolator 200 with the first boundary line 330 and align the second boundary 220 of the isolator 200 with the second boundary line 340, and then adjust the position of the isolator 200 along the width direction thereof, so as to align the third boundary 230 of the isolator 200 with the third boundary line 350 and align the fourth boundary 240 of the isolator 200 with the fourth boundary line 360. The method for mounting the isolator on the fiber array by the glue positioning under the assistance of the microscope platform 400 is advantageous in further improving the mounting precision of the limiting plate 550, so as to improve the mounting precision of the isolator 200 and the fiber center 110.

[0124] Referring to Figure 6 , Figure 9 and Figure 17 , in step S370, after the user adjusts the position of the isolator 200 to the right position, i.e., after the isolator 200 is placed in the mounting area and each boundary of the isolator 200 is aligned with each boundary line of the mounting area, the method for mounting the isolator on the fiber array can be implemented by the ultraviolet curing method, so as to accelerate the curing of the liquid glue at the position of the fiber center 110, thereby realizing the relative fixation of the isolator 200 and the fiber array 100, and avoiding the contact with the isolator 200, so as to ensure the mounting accuracy of the isolator 200 and the fiber array 100.

[0125] Referring to Figures 10 to 17 , the mounting equipment of one embodiment of the present application can be used to implement the method for mounting the isolator on the fiber array as shown in any one of the above embodiments. The mounting equipment can implement step S100 to step S300 as shown in Figure 1 , step S210 to step S220 as shown in Figure 2 , step S230 to step S260 as shown in Figure 3 , step S310 to step S350 as shown in Figure 4 , and step S360 to step S370 as shown in Figure 5 .

[0126] Specifically, the mounting device comprises a clamping assembly, a microscope platform 400 and an adjusting assembly 560.

[0127] Referring to Figure 10 , Figure 15 and Figure 16 , the clamping assembly comprises a clamping seat 510 and a positioning member, the clamping seat 510 is provided with a clamping station 511 for accommodating the optical fiber array 100, and the optical fiber array 100 is positioned by respectively abutting each end face of the optical fiber array 100 with each wall face of the clamping station 511. When the optical fiber array 100 and the clamping seat 510 are positioned, the method for mounting the optical fiber array 100 and the isolator can fix the relative position relationship between the optical fiber array 100 and the clamping seat 510 through the positioning member.

[0128] Referring to Figure 10 , Figure 11 and Figure 13 , the microscope platform 400 comprises a base and a microscope assembly, the lower end of the clamping assembly is connected with the base, so that the microscope is arranged on the upper end of the clamping assembly, and the microscope platform 400 is configured to obtain a marking image of the mounting end face 120 of the optical fiber array 100 located in the clamping station 511. Through the positioning of the optical fiber array 100 in the clamping station 511, the positioning accuracy of the optical fiber array 100 is improved, and the accuracy of the marking image acquisition is also improved. According to the marking image, a calibration center 370 corresponding to the optical fiber center 110 of the optical fiber array 100 can be marked on the microscope platform 400, and according to the mounting requirements of the isolator 200 relative to the optical fiber center 110, that is, according to the product requirements of the isolator 200 relative to the optical fiber center 110, a mounting area of the isolator 200 relative to the calibration center 370 after being enlarged by a preset multiple can be marked in the microscope platform 400. The marking image is enlarged by a preset multiple through the microscope platform 400, so as to improve the accuracy of the marking. According to the relative position relationship between the existing calibration center 370 and the mounting area, the subsequent mounting process can be guided.

[0129] Referring to Figure 10 , Figure 11 and Figure 12As shown, the method of mounting the fiber array mounting isolator further comprises an adjusting assembly 560, which is configured to adjust the relative position of the clamping assembly and the microscope platform 400 to assist in achieving the alignment of the fiber center 110 of the fiber array 100 to be mounted and the calibration center 370. In the subsequent mounting process, the user can fix the fiber array 100 to be mounted on the clamping assembly, and adjust the relative position of the clamping assembly and the microscope platform 400 through the adjusting assembly 560, so that the fiber center 110 of the fiber array 100 after magnification is aligned with the calibration center 370, and then the isolator 200 is mounted on the mounting end face 120, and the position of the isolator 200 is adjusted according to the mounting area, so that the isolator 200 is placed in the mounting area, so that the isolator 200 is aligned with the mounting area, thereby improving the mounting accuracy of the isolator 200 and the fiber center 110.

[0130] Referring to Figure 10 , Figure 11 and Figure 13 As shown, the mounting device magnifies and marks the obtained mounting actual data to obtain accurate guidance data, and assists in the subsequent mounting process according to the guidance data, thereby improving the mounting precision of the isolator 200 and the fiber array 100.

[0131] Referring to Figure 14 , Figure 15 and Figure 16 As can be understood, specifically, the clamping seat 510 is provided with a positioning groove 512 with an upward opening, and the clamping seat 510 is provided with a baffle 540 at the opening of the positioning groove 512. The baffle 540 can partially close the upper end opening of the positioning groove 512, so that the lower wall surface of the baffle 540 and the multiple wall surfaces of the positioning groove 512 in the circumferential direction jointly define the clamping station 511. The width of the positioning groove 512 along the left-right direction is matched with the width of the fiber array 100 along the left-right direction, so as to facilitate the alignment and positioning of the fiber array 100 and the positioning groove 512.

[0132] Referring to Figure 14 , Figure 15 and Figure 16 Specifically, the positioning member comprises a fixed block 520 and a first threaded member 530, the fixed block 520 is fixed with the clamping seat 510, and the fixed block 520 is provided with a first screw hole opposite to the clamping station 511. Specifically, the positioning groove 512 is open rearward and is arranged opposite to the first screw hole. The first threaded member 530 is threadedly connected with the first screw hole on the fixed block 520, so that the first threaded member 530 can be close to or away from the clamping station 511.

[0133] Referring to Figure 14 , Figure 15 and Figure 16As shown, in use, the user can place the fiber array 100 into the positioning groove 512, with the fiber center 110 of the fiber array 100 facing upwards, and with the left end face of the fiber array 100 abutting the left wall face of the positioning groove 512 and the right end face of the fiber array 100 abutting the right wall face of the positioning groove 512, by applying pressure to the fiber array 100 from back to front, so that the front end face of the fiber array 100 abuts the front wall face of the positioning groove 512, and by applying pressure to the fiber array 100 from bottom to top, so that the upper end face of the fiber array 100 abuts the lower wall face of the baffle 540, to achieve the initial positioning of the fiber array 100 and the clamping station 511, and then the user can rotate the first threaded member 530, through the threaded connection between the first threaded member 530 and the first threaded hole of the fixed block 520, so that the first threaded member 530 approaches the positioning groove 512, and so that the first threaded member 530 abuts the rear end face of the fiber array 100, to achieve the relative fixation of the fiber array 100 and the clamping seat 510.

[0134] Referring to Figure 14 , Figure 15 and Figure 16 , the method for attaching the fiber array isolator improves the positioning accuracy of the fiber array 100 through the cooperation of the positioning groove 512, the baffle 540 and the positioning member, and thereby improves the accuracy of the mark image acquisition.

[0135] Referring to Figure 10 , Figure 11 and Figure 12 , it can be understood that the clamping seat 510 is inclined from back to front from bottom to top, so that the positioning groove 512 is inclined from back to front from bottom to top, to compensate for the surface slope of the fiber array 100 at the attachment end face 120. When the user positions and fixes the fiber array 100 in the clamping station 511, due to the inclined arrangement of the positioning groove 512, the attachment end face 120 is arranged horizontally, so as to facilitate the attachment of the isolator 200 on the attachment end face 120, and to more accurately adjust the position of the isolator 200, which is beneficial to eliminate the defect that the isolator 200 is not easy to position due to the inclination of the attachment end face 120.

The attachment device converts virtual guidance into physical limiting guidance of the limiting plate 550 by gluing and attaching the limiting plate 550, so that in the subsequent attachment process, the first boundary 210 of the isolator 200 can be aligned with the first boundary line 330 by abutting the edge of the limiting plate 550 close to the fiber center 110, and the gluing and positioning under the assistance of the microscope platform 400 can further improve the attachment precision of the limiting plate 550 and improve the attachment precision of the isolator 200 and the fiber center 110.
