Description

Technical Field

[0001] This invention relates to the field of fiber optic array assembly equipment technology, and in particular to a two-dimensional hybrid fiber optic array assembly equipment. Background Technology

[0002] Two-dimensional hybrid fiber arrays (2D-FAs) are core coupling components for high-speed coherent optical modules, fiber optic gyroscopes, planar waveguides (PLCs), and integrated photonic chips. They achieve high-precision integrated positioning of multiple fiber optic channels through array vias on the substrate and are compatible with both conventional and polarization-maintaining fiber assemblies. The manufacturing process of 2D-FAs involves inserting multiple fibers into array vias on the substrate and injecting curing adhesive to rigidly fix the fibers to the substrate. The polarization-maintaining fibers require uniform calibration of the horizontal polarization angle of the cat's-eye stress bar to ensure that key optical indicators such as extinction ratio and coupling loss meet standards. This process is achieved using a 2D-FA assembly device.

[0003] In related technologies, the two-dimensional hybrid fiber array assembly device lacks a layered support and limiting structure. When assembling multiple layers of fibers in a two-dimensional hybrid fiber array, the upper polarization-maintaining fiber tail is prone to drooping and twisting due to its own gravity, causing random shifts in the polarization angle of the polarization-maintaining fiber. Furthermore, there is no physical isolation structure during the synchronous core-alignment of multiple polarization-maintaining fibers. When rotating and aligning a single polarization-maintaining fiber, it is easy to cause adjacent polarization-maintaining fibers that have already been calibrated to deflect at an angle. Ultimately, this results in the dispersion of the polarization angle of the polarization-maintaining fiber in the finished fiber array, which seriously reduces the product yield of the two-dimensional hybrid fiber array. Summary of the Invention

[0004] The main objective of this invention is to propose a two-dimensional hybrid fiber array assembly device, which aims to solve the technical problem of poor polarization angle consistency of polarization-maintaining fibers during the assembly of two-dimensional hybrid fiber arrays in the prior art, and improve the product yield of two-dimensional hybrid fiber arrays.

[0005] To achieve the above objectives, the two-dimensional hybrid fiber array assembly device proposed in this invention includes: The base, wherein the base is provided with a first bearing portion; A limiting mechanism is provided opposite to the first bearing part; A layered component, the layered component having a first receiving channel and a second supporting portion distributed along a first direction, the first receiving channel penetrating the layered component along a second direction and being disposed opposite to the first supporting portion; A partition assembly includes a partition body and a plurality of partition members. The partition body forms a second receiving channel and a third supporting portion distributed along a first direction. The second receiving channel passes through the partition body along a second direction and is disposed opposite to the first receiving channel. The plurality of partition members are distributed along a third direction in the third supporting portion. The separating component, the layering component, and the limiting mechanism are sequentially disposed on one side of the base along the second direction.

[0006] In one embodiment, the layered assembly includes a plurality of layered components stacked along a first direction. The layered component has a first receiving channel on the side near the base and a second bearing portion on the side away from the base. The layered component is detachably connected to the base.

[0007] In one embodiment, the layered assembly further includes a fastener that sequentially connects a plurality of the layered components and is connected to the base.

[0008] In one embodiment, the fixing member is fixedly connected to the base, the layered member is provided with positioning holes, and the fixing member is inserted into the positioning holes.

[0009] In one embodiment, the partition body is detachably connected to the base, the partition assembly has a second receiving channel on the side near the base, and the partition assembly has a third bearing portion on the side away from the base.

[0010] In one embodiment, the partition body further has a connecting surface that connects the third support portion and the second support portion, and the connecting surface is gradually disposed closer to the base along the direction from the third support portion to the second support portion.

[0011] In one embodiment, the base is further provided with an optical fiber positioning element, which is located on the side of the first bearing portion near the layered assembly. The positioning element is provided with a plurality of optical fiber positioning slots distributed along a third direction, and the optical fiber positioning slots extend along a second direction.

[0012] In one embodiment, the limiting mechanism includes a clamping component and a pressing component; The clamping assembly forms a clamping space, which is disposed opposite to the first bearing portion, and the clamping assembly is configured to move along a third direction to expand or shrink the clamping space; The pressing component is disposed opposite to the first bearing portion, and the pressing component is configured to move along a first direction to approach or move away from the first bearing portion.

[0013] In one embodiment, the base is provided with a clearance groove, and a slide bar extending in a third direction is provided in the clearance groove. The clamping assembly includes a fixed part, a movable part, and a first elastic element. The fixed part is fixedly connected to the base, the movable part extends into the clearance groove and forms a sliding hole, the slide rod slides through the sliding hole, and the first elastic member connects the movable part and the base and is configured to drive the movable part closer to the fixed part.

[0014] In one embodiment, the pressing assembly includes: A guide rod is screwed to the base and extends along a first direction, and the guide rod is provided with a limiting part that is spaced apart from the base; A movable component, which is slidably sleeved on the guide rod and at least partially limited between the limiting portion and the base, wherein the movable component is provided with a groove extending in a third direction; A holding member, the holding member including a holding portion and a sliding portion, the sliding portion extending at least partially along a third direction and slidingly engaging with the slide groove, the holding portion being rotatably connected to the sliding portion and disposed opposite to the first bearing portion; A second elastic element connects the limiting portion and the movable element, and is configured to drive the movable element closer to the base.

[0015] The technical solution of this invention achieves physical isolation between the ordinary fiber layer and the polarization-maintaining fiber layer in a two-dimensional hybrid fiber array, as well as physical isolation between multiple polarization-maintaining fibers within the same layer, through the coordinated cooperation of layered components and separator components. Specifically, the limiting mechanism cooperates with the first carrier part to limit the substrate in the fiber array. The first and second receiving channels provide a through path for the ordinary fiber, while the first and second carrier parts provide stable support for the polarization-maintaining fiber. Multiple separators are distributed along a third direction, forming an independent core-aligning station between each pair of separators. This ensures that when a single polarization-maintaining fiber is rotated and aligned to adjust the cat's-eye polarization angle, adjacent fibers are physically blocked, avoiding the problem of adjacent fibers being deflected during core alignment of a single fiber. Furthermore, the second and third carrier parts jointly support the polarization-maintaining fiber, increasing the support points for the polarization-maintaining fiber in its extension direction, avoiding random polarization angle shifts caused by the drooping and twisting of the upper polarization-maintaining fiber. Therefore, the consistency of the polarization angle of the polarization-maintaining fiber is improved, increasing the product yield of the two-dimensional hybrid fiber array.

[0023] This invention proposes a two-dimensional hybrid fiber array assembly device 100.

[0024] Please see Figures 1 to 3 In one embodiment of the present invention, the two-dimensional hybrid fiber array assembly device 100 includes a base 1, a limiting mechanism 2, a layering component 3, and a separating component 4. The separating component 4, the layering component 3, and the limiting mechanism 2 are sequentially disposed on one side of the base 1 along a second direction. The base 1 is provided with a first bearing portion 11. The limiting mechanism 2 is disposed opposite to the first bearing portion 11. The layering component 3 forms a first receiving channel 31a and a second bearing portion 311 distributed along a first direction. The first receiving channel 31a passes through the layering component 3 along the second direction and is disposed opposite to the first bearing portion 11. The separating component 4 includes a separating body 41 and a plurality of separating elements 42. The separating body 41 forms a second receiving channel 41a and a third bearing portion 411 distributed along the first direction. The second receiving channel 41a passes through the separating body 41 along the second direction and is disposed opposite to the first receiving channel 31a. The plurality of separating elements 42 are distributed along a third direction on the third bearing portion 411.

[0025] It should be noted that the first direction, the second direction, and the third direction intersect each other. Optionally, the first direction, the second direction, and the third direction can be perpendicular to each other. Alternatively, the first direction can be a vertical direction, and the second direction and the third direction can both be parallel to the horizontal plane. The second direction can be the length direction of the base 1, and the third direction can be the width direction of the base 1.

[0026] In this embodiment, the base 1 provides the foundation for installation and support of the entire device. The first support part 11 can be set as the support area on the surface of the base 1 to support the glass substrate 210 of the two-dimensional hybrid fiber array 200. The surface of the first support part 11 can be a horizontal plane to ensure that the glass substrate 210 is placed stably and to avoid the substrate 210 tilting and affecting the accuracy of fiber polarization angle calibration.

[0027] The limiting mechanism 2 is arranged opposite to the first support part 11 and is used to cooperate with the first support part 11 to limit the position of the glass substrate 210 placed on the first support part 11, preventing the substrate 210 from shifting during assembly. The limiting mechanism 2 can adopt an adjustable clamping structure to adapt to glass substrates 210 of different specifications, or it can adopt a fixed structure to achieve rapid positioning of glass substrates 210 of a specific size to adapt to a single specification of glass substrate 210. This embodiment does not limit the specific structure of the limiting mechanism 2. Through the cooperation of the limiting mechanism 2 and the first support part 11, the substrate 210 of the two-dimensional hybrid fiber array 200 can be ensured to maintain a stable position during assembly, providing a position reference for subsequent fiber insertion, core alignment and curing operations.

[0028] The layering component 3 is used for layered support and guidance of ordinary optical fiber 220 and polarization-maintaining optical fiber 230. The second support part 311 and the first receiving channel 31a are distributed along the first direction to support the optical fiber of the corresponding layer. Specifically, the first receiving channel 31a is through-passed along the second direction, allowing ordinary single-mode optical fiber to pass through, thus achieving routing avoidance for the ordinary optical fiber 220 layer; the second support part 311 can provide support points for the polarization-maintaining optical fiber 230 along the extension direction. The layering component 3 can adopt a block-shaped or plate-shaped structure. It should be noted that in the two-dimensional hybrid optical fiber array 200, when there are multiple layers of ordinary optical fiber 220, the number of first receiving channels 31a can be increased accordingly. As shown in Figure n, when the two-dimensional hybrid optical fiber array 200 contains two layers of ordinary optical fiber 220, the layering component 3 can be provided with two first receiving channels 31a distributed along the first direction. It can be understood that when the two-dimensional hybrid optical fiber array 200 contains two or more layers of ordinary optical fiber 220, the number of first receiving channels 31a can be increased accordingly, and this embodiment does not limit this. It should also be noted that when the layered component 3 has two or more first receiving channels 31a, the layered component 3 can adopt an integrated structure or a split structure. When adopting an integrated structure, the layered component 3 has multiple first receiving channels 31a at the same time. When adopting a split structure, each split structure can have one first receiving channel 31a.

[0029] In the separator assembly 4, the separator body 41 provides the mounting base for the separator 42. The second receiving channel 41a is connected to the first receiving channel 31a, allowing ordinary single-mode optical fibers to pass through continuously. The third bearing part 411 is used to support the extension section of the polarization-maintaining optical fiber 230. Multiple separators 42 are arranged at intervals along the third direction, forming independent optical fiber receiving spaces between adjacent separators 42. The separators 42 can take the form of sheet structure, column structure, etc., and this embodiment does not limit this. The arrangement spacing of the separators 42 can be adapted to the outer diameter of the optical fiber to ensure that an effective physical barrier is formed between adjacent optical fibers.

[0030] Based on the above description, the limiting mechanism 2, in conjunction with the first carrier part 11, limits the substrate in the fiber array. The first receiving channel 31a and the second receiving channel 41a provide a through path for the ordinary optical fiber 220, while the first carrier part 11 and the second carrier part 311 provide stable support for the polarization-maintaining fiber 230. Multiple separators 42 are distributed along the third direction, forming an independent core-aligning station between every two separators 42. This ensures that when a single polarization-maintaining fiber 230 is rotated and calibrated to adjust the cat's-eye polarization angle, adjacent fibers are physically blocked, avoiding the problem of adjacent fibers being deflected during core alignment of a single fiber. Furthermore, the second carrier part 311 and the third carrier part 411 jointly support the polarization-maintaining fiber 230, increasing the support points for the polarization-maintaining fiber 230 in its extension direction, preventing random polarization angle shifts caused by the drooping and twisting of the upper polarization-maintaining fiber 230. Therefore, the consistency of the polarization angle of the polarization-maintaining fiber 230 is improved, increasing the product yield of the two-dimensional hybrid fiber array 200.

[0031] Please see Figure 3 In one embodiment of the present invention, the layered component 3 includes a plurality of layered members 31 stacked along a first direction. The layered member 31 is provided with a first receiving channel 31a on the side near the base 1 and a second bearing portion 311 on the side away from the base 1. The layered member 31 is detachably connected to the base 1.

[0032] In this embodiment, the layering member 31 can be a plate-like or block-like structure, with each layering member 31 corresponding to a layer of optical fiber. The first receiving channel 31a can be configured as a through-slot structure on the side of the layering member 31 facing the base 1, used to avoid and guide the ordinary single-mode optical fiber of the corresponding layer, so that the ordinary optical fiber 220 can pass through the layering member 31 along the second direction without interfering with the polarization-maintaining optical fiber 230. The second supporting part 311 can be configured as a supporting area on the surface of the layering member 31, used to support the polarization-maintaining optical fiber 230 of the corresponding layer, providing support for the polarization-maintaining optical fiber 230 in the layer along the extension direction. The second supporting part 311 can be planar.

[0033] Multiple layered components 31 are stacked sequentially along the first direction, and the polarization-maintaining fiber 230 layers can be placed in the second support portion 311 of the layered component 31 furthest from the base 1. The shape and size of each layered component 31 can be kept consistent, so the positions of any two layered components 31 can be interchanged, and there is no need to distinguish the order during assembly, which simplifies the assembly process.

[0034] The detachable connection between the layer component 31 and the base 1 can be achieved through a plug-in engagement or a bolt-locking method; this embodiment does not limit this. The detachable connection between the layer component 31 and the base 1 can be adjusted according to the actual number of layers in the two-dimensional hybrid fiber array 200, adapting to the assembly requirements of two-dimensional hybrid fiber arrays 200 with different layer counts and improving the adaptability of the layer component 3 to fiber arrays with different layer counts. For example, a socket can be provided on the side of the base 1 and each layer component 31 away from the base 1, and a plug-in protrusion can be provided on the side of each layer component 31 close to the base 1. The engagement of the plug-in protrusion with the socket enables rapid positioning and connection between the layer component 31 and the base 1, as well as between adjacent layer components 31.

[0035] Please see Figure 1 and Figure 3 In one embodiment of the present invention, the layered component 3 further includes a fixing member 32, which is connected to a plurality of layered components 31 in sequence and connected to the base 1.

[0036] In this embodiment, the fixing member 32 can be a rod-shaped or strip-shaped structure, used for overall positioning and fastening of multiple stacked layered components 31. The fixing member 32 extends along the first direction and sequentially passes through multiple stacked layered components 31, connecting each layered component 31 in series into a whole. The end of the fixing member 32 is connected to the base 1, so that the series-connected layered assembly 3 is fixed to the base 1 as a whole. The fixing member 32 can be plugged into, threadedly connected to, or fixedly connected to the base 1; this embodiment does not limit this.

[0037] By connecting multiple layered components 31 in series with the fixing member 32, the interlayer spacing between each layered component 31 can be kept stable, preventing relative displacement of the layered components 31 during assembly or core alignment, and ensuring the coaxiality of the first receiving channel 31a and the parallelism of the second bearing part 311 of each layer. Simultaneously, the fixing member 32 fixes the layered assembly 3 as a whole to the base 1, which can improve the overall structural rigidity of the layered assembly 3 and reduce deformation and swaying of the layered assembly 3 during fiber insertion and rotational core alignment. Therefore, this embodiment, through the setting of the fixing member 32, strengthens the connection reliability and overall positioning accuracy between the multiple layered components 31, and improves the structural stability of the layered assembly 3.

[0038] Please see Figure 3 In one embodiment of the present invention, the fixing member 32 is fixedly connected to the base 1, the layered member 31 is provided with a positioning hole 31b, and the fixing member 32 is inserted into the positioning hole 31b.

[0039] In this embodiment, the fastener 32 and the base 1 can be fixedly connected by interference fit, welding or screwing, or integrally formed with the base 1, etc., and this embodiment does not limit the specific method. The extension direction of the fastener 32 is consistent with the first direction to adapt to the layout of the layered components 31 stacked along the first direction.

[0040] The positioning hole 31b can be formed in the area near the edge of the layered member 31 to avoid obstructing the first receiving channel 31a. The positioning hole 31b penetrates the layered member 31 along the first direction. The cross-sectional profile of the positioning hole 31b can be adapted to the cross-sectional profile of the fixing member 32 so that the fixing member 32 can be smoothly inserted and form a stable fit. The layered member 31 can be provided with one or more positioning holes 31b. When one positioning hole 31b is provided, the shapes of the positioning hole 31b and the fixing member 32 can be square, regular polygonal, elliptical, etc., to prevent the layered member 31 from rotating around the fixing member 32. When two or more positioning holes 31b are provided, the shapes of the positioning hole 31b and the fixing member 32 can be circular.

[0041] The insertion and engagement of the positioning holes 31b with the fixing members 32 facilitates the increase or decrease of the number of layered components 31, thereby flexibly adapting to two-dimensional hybrid fiber arrays 200 with different layer counts. During assembly, the operator only needs to align the positioning holes 31b of each layered component 31 with the fixing members 32 and then stack them sequentially on the base 1 to quickly complete the assembly and positioning of the layered components 3, improving the assembly efficiency of the layered components 31.

[0042] Please see Figure 1 and Figure 3 In one embodiment of the present invention, the separating body 41 is detachably connected to the base 1, the separating component 4 is provided with a second receiving channel 41a on the side near the base 1, and a third bearing part 411 is provided on the side of the separating component 4 away from the base 1.

[0043] In this embodiment, the separator body 41 can be a block or plate structure, serving as the supporting base 210 for the separator component 4, providing an installation foundation for the separator 42, and simultaneously forming a space for accommodating and routing optical fibers. The separator body 41 and the base 1 can be detachably connected via a plug-in connection or by bolt locking; this embodiment does not limit this. Because the separator body 41 and the base 1 are detachably connected, the separator component 4 of the corresponding size can be replaced according to the specifications of the optical fiber array, adapting to the assembly requirements of two-dimensional hybrid optical fiber arrays 200 with different channel numbers and different optical fiber outer diameters.

[0044] Specifically, the second receiving channel 41a is located on the side of the separator 4 near the base 1, extending along the second direction and penetrating the separator body 41. It is aligned with the first receiving channel 31a of the layering component 3, allowing ordinary single-mode optical fiber to pass through the separator 4 along the second direction, thus enabling continuous routing of the ordinary optical fiber 220 and preventing interference between the ordinary optical fiber 220 and the polarization-maintaining optical fiber 230. The cross-sectional dimensions of the second receiving channel 41a can be adapted to the arrangement dimensions of the corresponding layer of ordinary optical fiber 220, ensuring smooth fiber insertion while allowing for reasonable allowance for movement.

[0045] The third support portion 411 is located in the support area on the side of the separator assembly 4 away from the base 1, and is used to support the polarization-maintaining fiber 230 extending from the layered assembly 3, providing support points for the polarization-maintaining fiber 230. The third support portion 411 can be horizontal. The third support portion 411 and the second support portion 311 are distributed sequentially along the second direction, forming multi-point support for the polarization-maintaining fiber 230. Multiple separators 42 are arranged on the third support portion 411 along the third direction, dividing the third support portion 411 into multiple independent placement positions for the polarization-maintaining fiber 230.

[0046] Please see Figure 1 and Figure 8 In one embodiment of the present invention, the separating body 41 is further provided with a connecting surface 412, which connects the third bearing portion 411 and the second bearing portion 311. The connecting surface 412 is disposed closer to the base 1 along the direction from the third bearing portion 411 to the second bearing portion 311.

[0047] In this embodiment, the connecting surface 412 can be a sloping structure or an arc structure, used to achieve a smooth connection between the second support portion 311 and the third support portion 411. The second support portion 311 is located closer to the base 1, which matches the arrangement of the array through holes on the glass substrate 210. Therefore, the polarization-maintaining fiber 230 and the ordinary fiber 220 in the area of ​​the layered component 3 are close together, and the arrangement of the polarization-maintaining fiber 230 in the same layer is also relatively compact. The ordinary fiber 220 passes through the first receiving channel 31a and the second receiving channel 41a, and the routing is always parallel to the top wall of the base 1, maintaining a stable routing height. The polarization-maintaining fiber 230 is supported and extended by the second support portion 311, smoothly transitions to the third support portion 411 through the connecting surface 412, gradually moves away from the base 1 along the direction of the connecting surface 412, and is finally supported on the third support portion 411.

[0048] The third carrier section 411 is farther from the base 1 than the second carrier section 311, allowing the polarization angle calibration of the polarization-maintaining fiber 230 to be performed on the side of the third carrier section 411 away from the second carrier section 311. In this region, the spacing along the first direction between the polarization-maintaining fiber 230 and the underlying ordinary fiber 220 is larger. During the rotation and core adjustment of a single polarization-maintaining fiber 230, the polarization-maintaining fiber 230 will not interfere with the underlying ordinary fiber 220. Simultaneously, the ample operating space also prevents accidental contact with adjacent fibers during core adjustment.

[0049] Based on the above description, this embodiment achieves the transition between the second carrier part 311 and the third carrier part 411 through the inclined connection surface 412. This not only matches the high-density arrangement requirements of the optical fiber on the glass substrate 210 side, but also increases the interlayer distance between the polarization-maintaining fiber 230 and the ordinary fiber 220 in the core-aligning operation area, eliminating the risk of interlayer interference, improving the convenience and calibration accuracy of the core-aligning operation, and further ensuring the consistency of the polarization angle of the polarization-maintaining fiber 230 in the batch of finished products.

[0050] It should be noted that in the relevant technologies, the assembly device does not have a pre-positioning structure and only supports the insertion of single optical fibers one by one. The alignment of the two-dimensional array of micro-through holes is difficult and the optical fibers are prone to bending, breakage, and misalignment, resulting in serious optical fiber material loss.

[0051] Please see Figure 4 To solve the above problems, in one embodiment of the present invention, the base 1 is further provided with an optical fiber positioning component 13. The optical fiber positioning component 13 is located on the side of the first bearing part 11 close to the layered component 3. The positioning component is provided with a plurality of optical fiber positioning grooves 13a distributed along a third direction. The optical fiber positioning grooves 13a are extended along a second direction.

[0052] In this embodiment, the fiber positioning component 13 can be fixed to the surface of the base 1 and is located between the glass substrate 210 placement area and the layering component 3, and is used to straighten and pre-position at least a portion of the optical fiber extending from the layering component 3 to the glass substrate 210.

[0053] Specifically, the fiber positioning groove 13a extends through the second direction, and the cross-sectional size of the groove can be adapted to the outer diameter of the fiber. This not only restricts the offset of the fiber along the third direction but also allows the fiber to pass smoothly through the second direction and rotate along its own axis. The cross-sectional size of the fiber positioning groove 13a can be V-shaped, U-shaped, semi-circular, etc., and this embodiment does not limit this. Multiple fiber positioning grooves 13a are arranged at intervals along the third direction, and the arrangement spacing can be adapted to the array through-hole spacing of the glass substrate 210. After the fiber extending from the layered component 3 is correspondingly embedded in a fiber positioning groove 13a, it can pass through a corresponding through-hole on the glass substrate 210. That is, the fiber positioning component 13 can pre-position and guide at least a portion of the fiber that passes through the layered component 3, reducing the alignment difficulty when the fiber passes through the array through-hole of the glass substrate 210, improving the efficiency and yield of the fiber threading operation, and reducing fiber material loss.

[0054] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the limiting mechanism 2 includes a clamping component 21 and a pressing component 22. The clamping component 21 forms a clamping space 21a, which is disposed opposite to the first bearing portion 11. The clamping component 21 is configured to move along a third direction to expand or shrink the clamping space 21a. The pressing component 22 is disposed opposite to the first bearing portion 11 and is configured to move along a first direction to move closer to or away from the first bearing portion 11.

[0055] In this embodiment, the clamping assembly 21 is used to clamp and limit the glass substrate 210 placed on the first support part 11, and the clamping space 21a is used to accommodate the glass substrate 210. The size of the clamping space 21a can be adjusted by the movement of the clamping assembly 21 in a third direction to adapt to glass substrates 210 of different specifications of two-dimensional hybrid fiber array 200. The clamping assembly 21 can adopt a structure with one side movable and one side fixed, or it can adopt a structure with both sides moving synchronously. This embodiment does not limit this.

[0056] The pressing component 22 is used to press and limit the glass substrate 210 placed on the first support part 11. When the pressing component 22 approaches the first support part 11 in the first direction, it can press the side of the glass substrate 210 away from the base 1, and together with the supporting effect of the first support part 11, it can limit the glass substrate 210 in the first direction. When the pressing component 22 moves away from the first support part 11 in the first direction, it can release the pressing, which facilitates the loading and unloading of the glass substrate 210.

[0057] The clamping assembly 21 and the pressing assembly 22 cooperate to form a multi-directional limiting effect on the glass substrate 210 on the first support portion 11. The clamping assembly 21 limits the position of the glass substrate 210 along a third direction, and the pressing assembly 22 limits the position of the glass substrate 210 along a first direction. Combined with the bottom support of the first support portion 11, the glass substrate 210 remains in a fixed position during assembly and will not shift or move.

[0058] It should be noted that in the relevant technology, the clamping of the glass substrate 210 relies on manual adjustment of the clamping strip for positioning, making it difficult to guarantee the consistency of clamping force. Furthermore, it can only be adapted to a single fixed width glass substrate 210 and cannot be compatible with glass substrates 210 of various specifications.

[0059] Please see Figure 4 , Figure 6 and Figure 7 To solve the above problems, in one embodiment of the present invention, the base 1 is provided with a clearance groove 1a, and a slide rod 12 extending in a third direction is provided in the clearance groove 1a. The clamping assembly 21 includes a fixed part 211, a movable part 212 and a first elastic member 213. The fixed part 211 is fixedly connected to the base 1. The movable part 212 extends into the clearance groove 1a and forms a sliding hole 212a. The slide rod 12 slides through the sliding hole 212a. The first elastic member 213 connects the movable part 212 and the base 1 and is configured to drive the movable part 212 to approach the fixed part 211.

[0060] In this embodiment, the clearance groove 1a can be formed on the side of the first supporting part 11, extending along a third direction, to accommodate a part of the structure of the movable part 212 and provide clearance space for the sliding of the movable part 212. The slide rod 12 is mounted inside the clearance groove 1a along a third direction, and both ends of the slide rod 12 can be fixedly connected to the side wall of the clearance groove 1a to provide guide support for the reciprocating sliding of the movable part 212. The slide rod 12 can be a cylindrical rod or a rod with other cross-sectional shapes, as long as it fits the sliding hole 212a of the movable part 212. This embodiment does not limit this.

[0061] The fixing part 211 is fixedly connected to the base 1. The fixing part 211 and the base 1 can be an integrally formed structure or fixedly connected by welding, detachable connection, or other methods. A portion of the movable part 212 extends out of the surface of the base 1 to form a clamping end, and the other portion extends into the clearance groove 1a and has a sliding hole 212a. The sliding hole 212a is provided through in a third direction, and the sliding rod 12 passes through the sliding hole 212a, so that the movable part 212 can slide back and forth in the extension direction of the sliding rod 12, thereby moving closer to or away from the fixing part 211. Optionally, the sliding hole 212a and the sliding rod 12 can be fitted with a clearance to ensure smooth sliding while limiting the offset of the movable part 212 in other directions and maintaining the accuracy of the clamping direction.

[0062] The first elastic element 213 can be an elastic structure such as a helical spring or a leaf spring. For example, when using a helical spring, the first elastic element 213 can be a compression spring, which can be sleeved on the slide rod 12, with one end abutting against the movable part 212 and the other end abutting against the side wall of the recess 1a. The first elastic element 213 can also be a tension spring, in which case both ends of the first elastic element 213 are respectively connected to the corresponding positions of the movable part 212 and the base 1. When the first elastic element 213 is in a compressed or stretched state, it continuously applies an elastic force toward the fixed part 211 to the movable part 212, driving the movable part 212 to move closer to the fixed part 211, thereby forming a clamping force on the glass substrate 210 placed between the fixed part 211 and the movable part 212.

[0063] When the glass substrate 210 needs to be placed, the movable part 212 can be moved along a third direction, causing it to slide away from the fixed part 211 along the slide bar 12. This expands the clamping space 21a. After the glass substrate 210 is placed on the first support part 11, the movable part 212 is released. The elastic force of the first elastic member 213 drives the movable part 212 to return to its original position and approach the fixed part 211, thereby clamping the glass substrate 210 between the fixed part 211 and the movable part 212. The elastic deformation of the first elastic member 213 can adaptively adjust the position of the movable part 212 according to the actual width of the glass substrate 210, achieving adaptive clamping of glass substrates 210 of different widths, with uniform and stable clamping force.

[0064] Based on the above description, the elastic clamping force provided by the first elastic element 213 automatically adapts to glass substrates 210 of different widths through elastic deformation, eliminating the need for manual adjustment of the clamping position and improving the efficiency of substrate 210 loading and the consistency of clamping force. Simultaneously, it avoids edge chipping of the glass substrate 210 caused by rigid clamping, ensuring the assembly quality and operational efficiency of the two-dimensional hybrid fiber array 200.

[0065] It should be noted that in the relevant technologies, the pressing structure uses a micrometer and a threaded screw to achieve lifting and adjustment. When loading and unloading workpieces, repeated rotation and adjustment are required, resulting in a long loading and unloading time for single products and a low overall production capacity for large-scale continuous production.

[0066] Please see Figure 5 , Figure 6 and Figure 8In one embodiment of the present invention, the pressing assembly 22 includes a guide rod 221, a movable member 222, a pressing member 223, and a second elastic member 224. The guide rod 221 is screwed to the base 1 and extends along a first direction. The guide rod 221 is provided with a limiting portion 2211 spaced apart from the base 1. The movable member 222 is slidably sleeved on the guide rod 221 and at least partially limited between the limiting portion 2211 and the base 1. The movable member 222 is provided with a sliding groove 222a extending along a third direction. The pressing member 223 includes a pressing portion 2231 and a sliding portion 2232. The sliding portion 2232 extends at least partially along a third direction and slides in cooperation with the sliding groove 222a. The pressing portion 2231 and the sliding portion 2232 are rotatably connected and are disposed opposite to the first bearing portion 11. The second elastic member 224 connects the limiting portion 2211 and the movable member 222 and is configured to drive the movable member 222 closer to the base 1.

[0067] In this embodiment, the guide rod 221 may be provided with external threads on its outer periphery, which cooperate with the corresponding threaded holes on the base 1 to realize the connection between the guide rod 221 and the base 1. The guide rod 221 extends along the first direction, and the limiting part 2211 may be provided at the end of the guide rod 221 away from the base 1, or it may be provided in the middle part of the guide rod 221. The limiting part 2211 and the base 1 form a sliding space for the movable member 222. The threaded connection between the guide rod 221 and the base 1 can be adjusted by rotating the guide rod 221 to adjust the distance between the limiting part 2211 and the base 1, thereby adjusting the sliding stroke of the movable member 222 and the initial preload of the second elastic member 224, adapting to glass substrates 210 of different thicknesses.

[0068] The movable component 222 can be a block structure with a guide hole extending along a first direction. A guide rod 221 passes through the guide hole, allowing the movable component 222 to slide back and forth along the extension direction of the guide rod 221. The sliding stroke of the movable component 222 is limited by the limiting part 2211 and the base 1 to prevent the movable component 222 from slipping. The movable component 222 has a sliding groove 222a extending along a third direction. The cross-sectional profile of the sliding groove 222a can be adapted to the cross-sectional profile of the sliding part 2232, providing sliding guidance for the lateral adjustment of the holding member 223.

[0069] The sliding portion 2232 of the holding member 223 extends along a third direction and at least partially extends into the groove 222a. It can slide back and forth along the extension direction of the groove 222a, driving the holding portion 2231 to adjust its position synchronously along the third direction. The sliding portion 2232 slides along the groove 222a, which can adjust the lateral position of the holding portion 2231 so that the holding portion 2231 corresponds to the geometric center position of glass substrates 210 of different widths. The holding portion 2231 and the sliding portion 2232 are rotatably connected. The holding portion 2231 can rotate relative to the sliding portion 2232 about an axis parallel to the second direction. This allows the holding portion 2231 to automatically adapt to the angle of the top surface of the substrate 210 when it presses down to contact the glass substrate 210, automatically level and fit the surface of the substrate 210, eliminate the influence of process errors, and avoid stress concentration that could damage the glass substrate 210.

[0070] The second elastic element 224 can be an elastic structure such as a helical spring or a spring sheet. For example, when a helical spring is used, the second elastic element 224 can be sleeved on the outer periphery of the guide rod 221, with one end abutting against the limiting part 2211 and the other end abutting against the movable part 222. The second elastic element 224 is in a compressed state and continuously applies an elastic force toward the base 1 to the movable part 222, driving the movable part 222 to slide along the guide rod 221 toward the base 1, thereby causing the pressing part 2231 to press against the glass substrate 210 placed on the first bearing part 11.

[0071] When loading the glass substrate 210, the movable member 222 can be moved away from the base 1, allowing it to slide along the guide rod 221 towards the limiting part 2211, compressing the second elastic member 224. The holding member 223 rises synchronously with the movable member 222, forming sufficient loading space between itself and the first bearing part 11. After placing the glass substrate 210 on the first bearing part 11 and completing the side clamping, the movable member 222 is released. The elastic restoring force of the second elastic member 224 drives the movable member 222 to reset, and the holding part 2231 presses against the top surface of the glass substrate 210, completing the top surface clamping and fixing of the substrate 210. When unloading, simply lift the movable member 222 to release the clamping; there is no need to repeatedly rotate and adjust the clamping height.

[0072] This embodiment utilizes the sliding engagement of the guide rod 221 and the movable part 222, combined with the elastic drive of the second elastic part 224, to replace the traditional lead screw and micrometer lifting and adjusting structure. This allows for rapid pressing and releasing of the glass substrate 210 through lifting and lowering actions, significantly reducing the loading and unloading time and improving the efficiency of large-scale continuous production. The pressing part 223 can be adjusted laterally along the slide groove 222a to accommodate glass substrates 210 of different widths, ensuring that the downward pressure load always acts on the geometric center of the substrate 210. The rotating leveling design of the pressing part 2231 automatically conforms to the surface of the substrate 210, eliminating localized stress concentration and preventing the thin glass substrate 210 from cracking under pressure. Stable pressing and fixing ensures the glass substrate 210 remains stable during fiber threading and core alignment, providing a stable reference for subsequent polarization angle calibration of the polarization-maintaining fiber 230.
