Description

Technical Field

[0001] This invention relates to the field of optical component technology, and in particular to a fiber optic integrated product processing fixture, method, and fiber optic integrated product. Background Technology

[0002] In the relevant technical field, fiber optic integrated products are used to connect two sets of optical devices. The product includes multiple polarization-maintaining fibers and multiple standard fibers. One end of each of the multiple polarization-maintaining fibers and multiple standard fibers is connected to a ferrule, the other end of the multiple polarization-maintaining fibers is connected to a polarization-maintaining fiber plug, and the other end of the multiple standard fibers is connected to a standard fiber plug.

[0003] To reduce the installation space required for the two sets of optical components, the ferrule must be arranged perpendicularly to the polarization-maintaining fiber plug and the standard fiber plug. This arrangement puts the polarization-maintaining fiber and the standard fiber in a twisted state. However, the stress bar of the polarization-maintaining fiber must be kept on the same plane at both ends, and the length accuracy requirements of the polarization-maintaining fiber and the standard fiber are high. The traditional processing method is to twist each polarization-maintaining fiber and each standard fiber individually and then fix them with adhesive. However, the length of such fiber optic integrated products is small, and there are no gaps between multiple polarization-maintaining fibers, making it impossible to adjust each fiber individually. This not only makes it difficult to determine the position of the stress bar of multiple polarization-maintaining fibers, but also results in low length accuracy of each polarization-maintaining fiber and each standard fiber after twisting, making it difficult to meet design requirements. This leads to low yield and low production efficiency of fiber optic integrated products. Summary of the Invention

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a processing fixture for optical fiber integrated products, which can simplify the processing method and improve processing accuracy and efficiency.

[0005] This invention also proposes a method for processing optical fiber integrated products using the aforementioned optical fiber integrated product processing fixture.

[0006] The present invention also proposes an optical fiber integrated product manufactured by the above-described optical fiber integrated product processing method.

[0007] According to a first aspect of the present invention, a fiber optic integrated product processing fixture includes a ferrule positioning seat and a plug positioning seat. The ferrule positioning seat has a first positioning groove in a vertical direction, the first positioning groove extending to one side of the ferrule positioning seat. A ferrule is vertically inserted into the first positioning groove, and the ferrule protrudes from the side wall of the ferrule positioning seat. The plug positioning seat is fixedly connected to the ferrule positioning seat. The plug positioning seat has a second positioning groove and a third positioning groove. The second positioning groove is aligned with the first positioning groove, and the second positioning groove extends in a vertical direction with its depth gradually increasing or decreasing in a direction away from the first positioning groove. A polarization-maintaining fiber optic plug is vertically inserted into the second positioning groove. The third positioning groove is arranged adjacent to the second positioning groove, and a standard fiber optic plug is inserted into the third positioning groove.

[0008] The fiber optic integrated product processing fixture according to embodiments of the present invention has at least the following beneficial effects: one end of multiple polarization-maintaining optical fibers is fixedly connected to a polarization-maintaining optical fiber plug, and one end of multiple standard optical fibers is fixedly connected to a standard optical fiber plug. The ferrule positioning seat and the plug positioning seat are fixedly connected, with a first positioning groove and a second positioning groove mating. The ferrule is vertically inserted into the first positioning groove, and the polarization-maintaining optical fiber plug is vertically inserted into the second positioning groove, so that both ends of the multiple polarization-maintaining optical fibers can be located between the ferrule and the polarization-maintaining optical fiber plug, and the multiple polarization-maintaining optical fibers are arranged vertically. By setting the second positioning groove to extend vertically and the groove depth to gradually increase or decrease in the direction away from the first positioning groove, the multiple polarization-maintaining optical fibers can be bent upwards or downwards, thereby quickly determining that the length of each polarization-maintaining optical fiber meets the length requirement after twisting. Moreover, the length of the polarization-maintaining optical fiber is determined without twisting, ensuring that the stress bars at both ends of the polarization-maintaining optical fiber are on the same plane, so that the positioning of multiple polarization-maintaining optical fibers in one operation can simultaneously meet the length and stress bar position requirements. In addition, the second and third positioning slots are arranged adjacent to each other. The standard fiber optic plug is inserted into the third positioning slot, which can quickly locate the distance between the ferrule and the standard fiber optic plug to determine the length of the standard fiber optic cable to improve the processing accuracy and efficiency.

[0009] According to some embodiments of the present invention, the third positioning slot is arranged in a horizontal direction, and the standard optical fiber plug is horizontally inserted into the third positioning slot.

[0010] According to some embodiments of the present invention, the third positioning groove is arranged at an angle from the end away from the first positioning groove toward the end closer to the first positioning groove, and the third positioning groove is arranged at an angle away from the second positioning groove.

[0011] According to some embodiments of the present invention, chamfers are provided between the sidewall of the second positioning groove and the sidewall of the plug positioning seat, and between the sidewall of the third positioning groove and the sidewall of the plug positioning seat.

[0012] According to some embodiments of the present invention, the number of the first positioning slot, the second positioning slot and the third positioning slot are all set to be multiple, and each first positioning slot corresponds to one second positioning slot and one third positioning slot.

[0013] According to some embodiments of the present invention, the ferrule positioning seat and the plug positioning seat are fixedly connected by a support rod.

[0016] One end of multiple polarization-maintaining fibers is assembled into the polarization-maintaining fiber plug, and the stress bars of the multiple polarization-maintaining fibers are located on the same plane. Then, the other end of the multiple polarization-maintaining fibers is passed through the ferrule.

[0017] One end of multiple standard optical fibers is assembled in the standard optical fiber plug, and the other end of the multiple standard optical fibers is passed through the ferrule.

[0018] The ferrule and the polarization-maintaining fiber plug are vertically inserted into the first positioning slot and the second positioning slot, respectively, and the standard fiber plug is inserted into the third positioning slot.

[0019] A thermosetting adhesive is applied to the end of the ferrule, and the ferrule is heated so that the thermosetting adhesive fixes the polarization-maintaining fiber and the standard fiber in the ferrule;

[0020] Trim the portion of the polarization-maintaining fiber and the standard fiber that protrudes from the ferrule.

[0021] The fiber optic integrated product processing method according to the embodiments of the present invention has at least the following beneficial effects: the fiber optic integrated product processing fixture of the first aspect of the present invention can replace the traditional processing method of twisting optical fibers one by one, which can not only adapt to fiber optic integrated products with shorter lengths, but also improve processing accuracy and efficiency, and increase yield.

[0022] According to some embodiments of the present invention, photosensitive adhesive is disposed between the polarization-maintaining fiber and the polarization-maintaining fiber plug, and between the standard fiber and the standard fiber plug, and is irradiated with ultraviolet light to fix the polarization-maintaining fiber and the standard fiber.

[0023] The fiber optic integrated product according to a third aspect of the present invention is manufactured by the fiber optic integrated product processing method according to a second aspect of the present invention.

[0024] The fiber optic integrated product according to the embodiments of the present invention has at least the following beneficial effects: the fiber optic integrated product processing method of the second aspect of the present invention can improve the processing accuracy of the fiber optic integrated product, so that the stress bars at both ends of the polarization-maintaining fiber can be located on the same plane, so that the lengths of the polarization-maintaining fiber and the standard fiber meet the design requirements, and improve the reliability of the fiber optic integrated product.

[0044] Understandably, referring to Figures 1 to 4The fiber optic integrated product processing fixture of the first aspect of the present invention includes a ferrule positioning seat 100 and a plug positioning seat 200. The ferrule positioning seat 100 has a first positioning groove 110 in the vertical direction, which extends to one side of the ferrule positioning seat 100. A ferrule 410 is vertically inserted into the first positioning groove 110 and protrudes from the side wall of the ferrule positioning seat 100. The plug positioning seat 200 is fixedly connected to the ferrule positioning seat 100. The plug positioning seat 200 has a second positioning groove 210 and a third positioning groove 220. The second positioning groove 210 is connected to the first positioning groove 110 and extends in the vertical direction. The groove depth gradually increases or decreases in the direction away from the first positioning groove 110. A polarization-maintaining fiber optic plug 420 is vertically inserted into the second positioning groove 210. The third positioning groove 220 is arranged adjacent to the second positioning groove 210. A standard fiber optic plug 430 is inserted into the third positioning groove 220.

[0045] One end of each of the multiple polarization-maintaining optical fibers 421 is fixedly connected to a polarization-maintaining optical fiber plug 420, and one end of each of the multiple standard optical fibers 431 is fixedly connected to a standard optical fiber plug 430. The ferrule positioning seat 100 and the plug positioning seat 200 are fixedly connected. The first positioning slot 110 and the second positioning slot 210 are aligned. The ferrule 410 is vertically inserted into the first positioning slot 110, the polarization-maintaining optical fiber plug 420 is vertically inserted into the second positioning slot 210, and the standard optical fiber plug 430 is inserted into the third positioning slot 220. Then, the ends of the polarization-maintaining optical fibers 421 furthest from the polarization-maintaining optical fiber plug 420 and the ends of the standard optical fibers 431 furthest from the standard optical fiber plug 430 are inserted into the ferrule 410, ensuring that the two ends of the multiple polarization-maintaining optical fibers 421 are positioned between the ferrule 410 and the polarization-maintaining optical fiber plug 420, and the two ends of the standard optical fibers 431 are positioned between the ferrule 410 and the standard optical fiber plug 430, with the multiple polarization-maintaining optical fibers 421 arranged vertically.

[0046] By setting the second positioning groove 210 to extend vertically and the groove depth to gradually increase or decrease in the direction away from the first positioning groove 110, multiple polarization-maintaining optical fibers 421 can be bent upward or downward, thereby quickly determining that the length of each polarization-maintaining optical fiber 421 meets the length requirements after twisting. Moreover, the length of the polarization-maintaining optical fiber 421 can be determined without twisting, ensuring that the stress bars 422 at both ends of the polarization-maintaining optical fiber 421 are on the same plane, so that the positioning of multiple polarization-maintaining optical fibers 421 can simultaneously meet the length and position requirements of the stress bars 422.

[0047] In addition, the second positioning slot 210 and the third positioning slot 220 are arranged adjacent to each other. The standard fiber optic plug 430 is inserted into the third positioning slot 220, which can quickly locate the distance between the ferrule 410 and the standard fiber optic plug 430, so as to determine the length of the processed standard fiber optic 431, thereby improving the processing accuracy and processing efficiency.

[0048] The ferrule 410 has a slot for accommodating the polarization-maintaining fiber 421 and the standard fiber 431. By setting the ferrule 410 to protrude from the side wall of the ferrule positioning seat 100, the protruding parts of the polarization-maintaining fiber 421 and the standard fiber 431 can be easily trimmed, thereby accurately determining the length of the polarization-maintaining fiber 421 and the standard fiber 431.

[0049] Reference Figure 5 , Figure 7 and Figure 8 The polarization-maintaining fiber 421 includes two stress bars 422, which extend to both ends of the polarization-maintaining fiber 421, so that when the polarization-maintaining fiber 421 is in a free state, the stress bars 422 at both ends are located on the same plane.

[0050] It should be noted that by vertically inserting the ferrule 410 into the first positioning groove 110 and the polarization-maintaining fiber plug 420 into the second positioning groove 210, the projections of the multiple polarization-maintaining fibers 421 on the horizontal plane coincide. By extending the second positioning groove 210 vertically and gradually increasing its depth away from the first positioning groove 110, the multiple polarization-maintaining fibers 421 can be bent and deformed vertically. This allows the length of the polarization-maintaining fiber 421 to be determined without flipping the polarization-maintaining fiber plug 420. On the one hand, this allows the length to be determined without twisting the polarization-maintaining fiber 421, improving the processing convenience of the polarization-maintaining fiber 421 and avoiding the torque affecting the processing accuracy. On the other hand, it replaces the traditional method of twisting the polarization-maintaining fiber 421 one by one, allowing multiple polarization-maintaining fibers 421 to be processed in one step, simplifying the processing and improving processing accuracy and efficiency.

[0051] Understandably, referring to Figure 3 and Figure 4 The third positioning slot 220 is arranged horizontally, and the standard fiber optic plug 430 is horizontally inserted into the third positioning slot 220. By setting the standard fiber optic plug 430 to be horizontally inserted into the third positioning slot 220, the ferrule 410 and the standard fiber optic plug 430 are arranged perpendicularly, which allows the standard fiber 431 to be in a twisted state. This ensures that the processing state of the standard fiber 431 is the same as the actual installation state, and thus the length of the standard fiber 431 can be determined more intuitively and accurately, which helps to reduce the length error of the standard fiber 431 and improve the processing accuracy of the standard fiber 431.

[0052] It should be noted that the standard optical fiber 431 does not have a stress bar 422, meaning that both ends of the standard optical fiber 431 can be twisted at any angle, as long as the length of the standard optical fiber 431 after twisting meets the design requirements. By setting the first positioning groove 110 to be arranged vertically and the third positioning groove 220 to be arranged horizontally, the ferrule 410 and the standard optical fiber plug 430 are arranged perpendicularly, making the processing state of the standard optical fiber 431 the same as the actual installation state. This allows for the rapid determination of the length of the standard optical fiber 431 and reduces the stress formed at the ferrule 410 and the standard optical fiber plug 430, thereby improving the connection reliability of the standard optical fiber 431.

[0053] Specifically, refer to Figure 3 and Figure 4 The third positioning groove 220 is arranged at an angle away from the first positioning groove 110 and towards the end closer to the first positioning groove 110. By setting the third positioning groove 220 at an angle away from the second positioning groove 210, after the standard fiber optic plug 430 is inserted into the third positioning groove 220, the standard fiber optic cable 431 can be kept away from the polarization-maintaining fiber 421. This avoids contact between the standard fiber optic cable 431 and the polarization-maintaining fiber 421, prevents the polarization-maintaining fiber 421 from bending in the horizontal direction, and ensures that the projection of the polarization-maintaining fiber 421 on the horizontal plane is a straight line. This facilitates the determination of the length of the polarization-maintaining fiber 421, helps reduce the length error of the polarization-maintaining fiber 421, and improves the product yield.

[0054] In addition, by setting the third positioning slot 220 to be inclined, it can adapt to the spatial layout of the fiber optic integrated product, optimize the relative positional relationship between the standard fiber optic plug 430, the polarization-maintaining fiber optic plug 420 and the ferrule 410, improve the structural compactness of the fiber optic integrated product processing fixture, and enhance the ease of use.

[0055] Understandably, referring to Figure 1 , Figure 2 and Figure 4 Chamfers 230 are provided between the sidewall of the second positioning groove 210 and the sidewall of the plug positioning seat 200, and between the sidewall of the third positioning groove 220 and the sidewall of the plug positioning seat 200. When the polarization-maintaining fiber optic plug 420 is vertically inserted into the second positioning groove 210 and the standard fiber optic plug 430 is inserted into the third positioning groove 220, the chamfers 230 guide the polarization-maintaining fiber optic plug 420 and the standard fiber optic plug 430 to smoothly insert into the second positioning groove 210 and the third positioning groove 220 respectively. This reduces the possibility of collision damage between the polarization-maintaining fiber optic plug 420 or the standard fiber optic plug 430 and the plug positioning seat 200, and reduces the possibility of damage to the ends of the polarization-maintaining fiber 421 or the standard fiber 431, thus helping to improve the processing quality of the polarization-maintaining fiber 421 and the standard fiber 431.

[0056] The chamfer 230 can be a rounded corner or a beveled corner, so that the first ends of the second positioning groove 210 and the third positioning groove 220 can form a tapered guide space to guide the polarization-maintaining fiber optic plug 420 or the standard fiber optic plug 430 to be inserted smoothly.

[0057] Understandably, referring to Figure 1 and Figure 4 The number of first positioning slots 110, second positioning slots 210, and third positioning slots 220 is set to multiple, with each first positioning slot 110 corresponding to one second positioning slot 210 and one third positioning slot 220. By setting the number of first positioning slots 110, second positioning slots 210, and third positioning slots 220 to multiple, the fiber optic integrated product processing fixture can process multiple fiber optic integrated products at once, improving the batch processing capacity of the fiber optic integrated product processing fixture, increasing production efficiency, and shortening the production cycle.

[0058] Understandably, referring to Figure 1 and Figure 3 The ferrule positioning seat 100 and the plug positioning seat 200 are fixedly connected by a support rod 300. The support rod 300 secures the ferrule positioning seat 100 and the plug positioning seat 200, increasing their connection strength and ensuring a stable relative position. This allows for accurate positioning of the ferrule 410, the polarization-maintaining fiber optic plug 420, and the standard fiber optic plug 430, improving processing precision.

[0059] It should be noted that the support rod 300 can be fixed between the ferrule positioning seat 100 and the plug positioning seat 200 by means of fastener connection, welding, adhesive, etc., which is not limited here.

[0060] Specifically, refer to Figure 1 and Figure 3 The ferrule positioning seat 100, plug positioning seat 200, and support rod 300 are integrally formed. By making the ferrule positioning seat 100, plug positioning seat 200, and support rod 300 integrally formed, the overall structural strength and stability of the fiber optic integrated product processing fixture are enhanced. This effectively avoids positioning deviations caused by fixture instability, thereby improving the positioning accuracy of fiber optic integrated products, ensuring product quality consistency, extending the service life of the fixture, and improving reliability.

[0061] Understandably, referring to Figure 6 The fiber optic integrated product processing method of the second aspect of the present invention is applied to the fiber optic integrated product processing fixture of the first aspect of the present invention. The fiber optic integrated product processing method includes:

[0062] S100 assembles one end of multiple polarization-maintaining optical fibers 421 into the polarization-maintaining optical fiber plug 420, and makes the stress bars 422 of the multiple polarization-maintaining optical fibers 421 lie on the same plane, and then passes the other end of the multiple polarization-maintaining optical fibers 421 through the ferrule 410.

[0063] S200 assembles one end of multiple standard optical fibers 431 into a standard optical fiber plug 430, and passes the other end of the multiple standard optical fibers 431 through a ferrule 410.

[0064] S300 vertically inserts the ferrule 410 and the polarization-maintaining fiber optic plug 420 into the first positioning slot 110 and the second positioning slot 210 respectively, and inserts the standard fiber optic plug 430 into the third positioning slot 220.

[0065] S400 applies thermosetting adhesive to the end of ferrule 410 and heats ferrule 410 so that the thermosetting adhesive fixes polarization maintaining fiber 421 and standard fiber 431 in ferrule 410.

[0066] The S500 trims the portion of polarization-maintaining fiber 421 and standard fiber 431 that protrudes from the ferrule 410.

[0067] By assembling one end of multiple polarization-maintaining fibers 421 into the polarization-maintaining fiber plug 420 and rotating each polarization-maintaining fiber 421 so that the stress bars 422 of the multiple polarization-maintaining fibers 421 are located on the same plane, the other ends of the multiple polarization-maintaining fibers 421 are then passed through the ferrule 410. Subsequently, one end of multiple standard fibers 431 is assembled into the standard fiber plug 430, and the other ends of the multiple standard fibers 431 are then passed through the ferrule 410 to initially position the polarization-maintaining fibers 421 and the standard fibers 431.

[0068] The ferrule 410 and the polarization-maintaining fiber plug 420 are vertically inserted into the first positioning slot 110 and the second positioning slot 210, respectively, so that the polarization-maintaining fiber 421 can be bent and deformed in the vertical direction. On the one hand, the length of each polarization-maintaining fiber 421 protruding from the ferrule 410 can be quickly determined, so that the length required for the actual installation state can be accurately determined without twisting multiple polarization-maintaining fibers 421. On the other hand, multiple polarization-maintaining fibers 421 can be lengthened at one time. This not only replaces the traditional method of twisting each polarization-maintaining fiber 421 individually, which is suitable for processing short fiber optic integrated products, but also accurately positions the stress bar 422 of the polarization-maintaining fiber 421, improving the yield rate of processing.

[0069] Inserting the standard fiber optic plug 430 into the third positioning slot 220 allows for quick determination of the length of the standard fiber optic cable 431 extending out of the ferrule 410, thereby accurately determining the length of the standard fiber optic cable 431 and improving processing efficiency.

[0070] Subsequently, thermosetting adhesive is applied to the end of the ferrule 410, and the ferrule 410 is heated so that the thermosetting adhesive can solidify on the ferrule 410, thereby fixing the polarization-maintaining fiber 421 and the standard fiber 431 in the ferrule 410. Then, the parts of the polarization-maintaining fiber 421 and the standard fiber 431 that protrude from the ferrule 410 are trimmed, thereby completing the processing of the fiber optic integrated product, which can improve processing efficiency and processing accuracy, and reduce processing costs.

[0071] It should be noted that the fiber optic integrated product processing fixture and the fiber optic integrated product can be placed together in the oven for heating, which can make the ferrule 410, polarization-maintaining fiber plug 420, polarization-maintaining fiber 421, standard fiber plug 430, and standard fiber 431 bear uniform force, so as to improve the length fixation accuracy of polarization-maintaining fiber 421 and standard fiber 431.

[0072] Understandably, referring to Figure 7 and Figure 8 Photosensitive adhesive is applied between the polarization-maintaining fiber 421 and the polarization-maintaining fiber plug 420, and between the standard fiber 431 and the standard fiber plug 430. This adhesive is then irradiated with ultraviolet light to fix the polarization-maintaining fiber 421 and the standard fiber 431 in place. By applying the photosensitive adhesive between the polarization-maintaining fiber 421 and the polarization-maintaining fiber plug 420, and between the standard fiber 431 and the standard fiber plug 430, multiple polarization-maintaining fibers 421 are positioned after being placed in the polarization-maintaining fiber plug 420, and multiple standard fibers 431 are positioned after being placed in the standard fiber plug 430. The photosensitive adhesive is then cured by ultraviolet light, facilitating the fixation of the polarization-maintaining fiber 421 and the standard fiber 431 and improving operational convenience.

[0073] Understandably, referring to Figure 7 The fiber optic integrated product of the third aspect of the present invention is manufactured by the fiber optic integrated product processing method of the second aspect of the present invention. By processing the fiber optic integrated product using the method of the second aspect of the present invention, the lengths of the polarization-maintaining fiber 421 and the standard fiber 431 meet the design requirements, and the stress bars 422 at both ends of the polarization-maintaining fiber 421 are located on the same plane, thereby improving the reliability of the fiber optic integrated product and meeting the design requirements.

[0074] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
