Description

Technical Field

[0001] The present invention relates to the technical field of optical cable processing, and particularly to a production method for AOC components. Background Art

[0002] An Active Optical Cable (AOC) refers to a communication cable that requires external energy during communication to convert electrical signals into optical signals or optical signals into electrical signals. The optical transceivers at both ends of the optical cable provide optical - electrical conversion and optical transmission functions.

[0003] When producing AOC component products, it is necessary to connect the ferrule and the optical cable with an optical fiber. In the prior art, the operator needs to first connect the ferrule and the optical fiber, and then connect the optical cable and the optical fiber, and then use an adhesive method for gluing. Due to the small size and thin thickness of the ferrule, it is very difficult to connect the optical fiber to the ferrule. Before the adhesive dries, the connection position between the ferrule and the optical fiber is likely to shift, resulting in the ferrule falling off or loosening and generating bubbles, which affects the product quality. Moreover, the optical cable is in a long - strip shape. To shorten the length of the optical cable for easy handling, the optical cable is usually wound up. However, the wound optical cable itself has a torsional force, which easily causes the position where the end of the optical cable is connected to the optical fiber to shift during the connection and dispensing processes, easily resulting in the fracture of the optical fiber, greatly increasing the production difficulty of AOC component products, and the product quality cannot be guaranteed. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. For this purpose, the present invention provides a production method for AOC components.

[0005] The solution of the present invention to solve its technical problems is as follows: A production method for AOC components uses an AOC component production tooling. The AOC component production tooling includes a positioning plate and an anti - springboard.

The front end of the optical fiber positioning groove communicates with the ferrule positioning groove, and the rear end of the optical fiber positioning groove communicates with the connector positioning groove. The anti - springboard is arranged above the connector positioning groove. The AOC component production method includes the following steps: Prepare the ferrule, optical fiber, and optical cable required for assembling the AOC component product. The front end of the optical cable has a connector; Place the connector into the connector positioning groove and press the connector tightly with the anti - springboard; Place the ferrule into the ferrule positioning groove; Place the optical fiber into the optical fiber positioning groove; Connecting the front end of the optical fiber to the ferrule by dispensing glue, and connecting the rear end of the optical fiber to the connector by dispensing glue; The positioning plate is heated until the glue at the optical fiber connection is cured.

[0006] The present invention has at least the following beneficial effects: the connector is positioned by the connector positioning groove of the AOC component production tooling, and the connector is pressed by the anti-jumping plate, which can prevent the connector from automatically jumping out of the connector positioning groove under the twisting force of the optical cable itself; the small and thin ferrule is positioned by the ferrule positioning groove, and the ferrule placed in the ferrule positioning groove cannot be shifted in the front and rear direction and the left and right direction under the restriction of the ferrule positioning groove, which is more convenient for the subsequent optical fiber connection and glue-pointing baking process; since the positions of the connector and the ferrule have been determined, the optical fiber is placed in the optical fiber positioning groove to achieve the fixed length of the optical fiber, and it can facilitate the connection between the optical fiber and the connector and the connection between the optical fiber and the ferrule; after the optical fiber, the ferrule and the connector are bonded by glue-pointing, the optical fiber, the ferrule and the optical cable form the required AOC component product, and then the glue is cured by heating and baking to obtain a product with good performance.

Each technical feature in the present invention can be combined interactively on the premise of not conflicting with each other.

[0024] An embodiment of the present invention provides a method for producing an AOC component. By using the production tooling for AOC components for production, the AOC component product 900 can be produced quickly and accurately, greatly reducing the production difficulty of the AOC component product 900 and improving the product quality.

[0025] Refer to Figure 5 and Figure 6 , the production tooling for AOC components used in the embodiments of the present invention includes a positioning plate 810 and an anti-jumping plate 820. Refer to Figure 7 , the positioning plate 810 is provided with a ferrule positioning groove 811, a connector positioning groove 812 and an optical fiber positioning groove. The front end of the optical fiber positioning groove communicates with the ferrule positioning groove 811, and the rear end of the optical fiber positioning groove communicates with the connector positioning groove 812. Among them, the ferrule positioning groove 811 is used to position the ferrule, the connector positioning groove 812 is used to position the connector 910 of the optical cable, and the optical fiber positioning groove is used to restrict the trend of the optical fiber. In this embodiment, the ferrule positioning groove 811, the connector positioning groove 812 and the optical fiber positioning groove are all arranged to open upward. The anti-jumping plate 820 is connected to the positioning plate 810 and is arranged above the connector positioning groove 812.

[0026] The method for producing an AOC component in the embodiment of the present invention includes step S100, step S200, step S300, step S400, step S500 and step S600. Refer to Figure 1 .

[0027] Step S100, prepare the ferrules, optical fibers and optical cables required for assembling the AOC component product 900. The front end of the optical cable has a connector 910. It can be understood that the AOC component product 900 assembled in this embodiment needs to connect the optical cable with the connector 910 through the optical fiber to the ferrule. The ferrule is small in volume and thin in thickness, and it is very difficult to connect the optical fiber to the ferrule. Moreover, due to the twisting force of the optical cable itself, it is easy for the optical cable connector to shift during the connection and dispensing processes, and it is easy to cause the optical fiber to break, greatly increasing the production difficulty of the AOC component product 900, and the quality of the product cannot be guaranteed.

[0028] Step S200: Place the connector 910 into the connector positioning groove 812 and press the anti-jumping plate 820 against the connector 910. Positioning the connector 910 through the connector positioning groove 812 of the AOC component production tooling and pressing the connector 910 with the anti-jumping plate 820 can prevent the connector 910 from automatically jumping out of the connector positioning groove 812 under the action of the twisting force of the optical cable itself.

[0029] It can be understood that the connector positioning groove 812 is set according to the shape and size of the connector 910. For the convenience of fiber access, the front end of the connector positioning groove 812 is open to achieve communication with the fiber positioning groove. For the convenience of the extension of the optical cable, the rear end of the connector positioning groove 812 is open, and the optical cable can extend from the rear end of the connector positioning groove 812.

[0030] In this embodiment, second card slots are respectively arranged on the left and right sides of the connector positioning groove 812, and second protrusions are respectively arranged on the left and right sides of the connector 910. The shape of the second protrusion matches the shape of the second card slot. When the connector 910 is placed into the connector positioning groove 812, the second protrusion is clamped in the second card slot, thereby realizing the positioning of the connector 910 in the front-rear direction. During the subsequent optical fiber connection process, the connector 910 cannot shift forward or backward.

[0031] Step S300: Place the ferrule into the ferrule positioning groove 811. Position the small-sized and thin-thickness ferrule through the ferrule positioning groove 811 of the AOC component production tooling in this embodiment. The ferrule placed in the ferrule positioning groove 811 cannot shift in the front-rear direction and the left-right direction under the restricting action of the ferrule positioning groove 811, which is more convenient for the subsequent optical fiber connection and glue dispensing and baking processes.

[0032] It can be understood that the shape and size of the ferrule positioning groove 811 are set according to the actually used ferrule. For the convenience of the connection between the optical fiber and the ferrule, the rear end of the ferrule positioning groove 811 is open to achieve communication between the ferrule positioning groove 811 and the fiber positioning groove.

[0033] The AOC component production tooling of this embodiment can perform high-precision length determination for AOC products with special-sized mini MT ferrules. It can be understood that the mini MT ferrule is an important core of a multi-channel data transmission device. Its volume is smaller than that of ordinary MT-type fiber connectors. Due to its small volume and thin wall thickness, the positioning and length determination are more difficult during optical fiber assembly.

[0034] In this embodiment, first card slots are respectively arranged on the left side and the right side of the ferrule positioning groove 811, first bumps are respectively arranged on the left side and the right side of the ferrule, and the shapes of the first bumps and the first card slots match each other. When the ferrule is placed into the ferrule positioning groove 811, the first bumps are clamped in the first card slots, which can prevent the ferrule from shifting in the front-back direction.

[0035] Step S400: Place the optical fiber into the optical fiber positioning groove. Since the positions of the connector 910 and the ferrule have been determined in step S200 and step S300, by placing the optical fiber into the optical fiber positioning groove in step S400, the fixed length of the optical fiber can be achieved, and moreover, the connection between the optical fiber and the connector 910 and the connection between the optical fiber and the ferrule can be facilitated.

[0036] Step S500: Connect the front end of the optical fiber to the ferrule by means of dispensing, and connect the rear end of the optical fiber to the connector 910 by means of dispensing. The front end of the optical fiber penetrates into the ferrule and is fixedly connected through an adhesive to achieve the connection between the optical fiber and the ferrule. The rear end of the optical fiber penetrates into the connector 910 and is fixedly connected through an adhesive to achieve the connection between the optical fiber and the connector 910.

[0037] Step S600: Heat the positioning plate 810 until the adhesive at the optical fiber connection is cured. It can be understood that the optical fiber can be well fixed through the cured adhesive, avoiding the situation of unstable connection between the optical fiber and the ferrule or the connector 910.

[0038] In some embodiments, referring to Figure 8 , the anti-jumping plate 820 includes a pressing plate 821 and a rotating shaft 823. The rotating shaft 823 is arranged on the left side or the right side of the joint positioning groove 812. The lower end of the rotating shaft 823 is connected to the positioning plate 810. The pressing plate 821 is rotatably connected to the rotating shaft 823, and the pressing plate 821 can rotate around the central axis of the rotating shaft 823. Among them, step S200 includes step S210, step S220 and step S230. Referring to Figure 2 .

[0039] Step S210: Toggle the pressing plate 821 and open the upper opening of the joint positioning groove 812. This step can be operated manually or by a manipulator, and no specific limitation is made here. When toggling the pressing plate 821, the pressing plate 821 rotates around the central axis of the rotating shaft 823. Referring to Figure 9 , the pressing plate 821 opens the joint positioning groove 812.

[0040] Step S220: Place the connector 910 into the joint positioning groove 812. This step can be operated manually or by a manipulator, and no specific limitation is made here.

[0041] Step S230, reverse the pressing plate 821 to press the upper surface of the connector 910. This step can be manually or robotically operated, and is not specifically limited here. When the pressing plate 821 is toggled, the pressing plate 821 rotates around the central axis of the rotating shaft 823. When the pressing plate 821 rotates above the joint positioning groove 812, the upper opening of the joint positioning groove 812 can be closed and the connector 910 can be pressed. Refer to Figure 10 .

[0042] The upper opening of the joint positioning groove 812 can be opened or closed by manually or robotically toggling the pressing plate 821. The operation is simple and fast. When the pressing plate 821 is rotated above the joint positioning groove 812, the pressing plate 821 can press the connector 910 located in the joint positioning groove 812, thereby avoiding the situation where the connector 910 jumps out of the joint positioning groove 812 and ensuring the fixed-length accuracy of the AOC component product 900.

[0043] In some embodiments, the anti-jumping plate 820 further includes a spring 825. The pressing plate 821 is provided with a rotating hole and a mounting groove. The rotating shaft 823 passes through the rotating hole and is detachably connected to the positioning plate 810. A blocking block 824 is provided at the upper end of the rotating shaft 823. The blocking block 824 is located above the rotating hole. The mounting groove is coaxially arranged with the rotating hole and is located at the upper end of the rotating hole. The spring 825 is sleeved on the outer periphery of the rotating shaft 823 and is arranged in the mounting groove. The lower end of the spring 825 abuts against the bottom of the mounting groove, and the upper end of the spring 825 abuts against the lower surface of the blocking block 824.

[0044] It can be understood that the blocking block 824 located at the upper end of the rotating shaft 823 can provide pressure to the spring 825. Under the elastic action of the spring 825, pressure can be provided to the pressing plate 821, so that the pressing plate 821 can further press the connector 910 and prevent the connector 910 from jumping out of the joint positioning groove 812. Moreover, since the spring 825 can stretch, there is a certain adjustment space for the distance between the lower end surface of the pressing plate 821 and the bottom of the joint positioning groove 812. The pressing plate 821 can press connectors 910 with different thicknesses, and the versatility is higher.

[0045] In addition, since the rotating shaft 823 is detachably connected to the positioning plate 810, after the rotating shaft 823 is detached from the positioning plate 810, it can be separated from the spring 825 and the pressing plate 821. The operator can replace the components of the positioning plate 810 and the anti-jumping plate 820 according to the actual situation, which is more convenient for the maintenance of the AOC component production tooling and ensures the fixed-length accuracy.

[0046] For the AOC component production tooling with a detachable rotating shaft 823 and positioning plate 810, when producing the AOC component product 900, before performing step S200, the AOC component production method further includes the steps of assembling the AOC component production tooling, specifically including step S710, step S720, and step S730. Refer to Figure 3 .

[0047] Step S710, place the spring 825 into the installation groove. It can be understood that by setting the installation groove, it can provide an installation space for the spring 825 and make the structure of the entire anti-skid plate 820 more reasonable.

[0048] Step S720, insert the rotating shaft 823 through the spring 825 and the rotation hole. It can be understood that a blocking block 824 is provided at the upper end of the rotating shaft 823. When installing the rotating shaft 823, insert the rotating shaft 823 downward from the upper end of the spring 825 so that the blocking block 824 abuts against the upper end of the spring 825.

[0049] Step S730, connect the lower end of the rotating shaft 823 to the positioning plate 810. In this embodiment, the rotating shaft 823 is a bolt, the bolt head at its upper end can be used as the blocking block 824, and a threaded structure is provided at its lower end, while a threaded hole is provided on the positioning plate 810. The threaded hole is located on the left or right side of the joint positioning groove 812. When installing the rotating shaft 823, connect the threaded structure at the lower end of the rotating shaft 823 to the hole wall of the threaded hole through thread fitting. The installation process is simple and fast.

[0050] It can be understood that when the spring 825 is installed in the installation groove, it can maintain a compressed state under the combined action of the blocking block 824 and the bottom of the installation groove.

[0051] It can be understood that when producing the AOC component product 900, the AOC component production tooling can be assembled once. After assembly, the AOC component production tooling can be left undismantled and used for assembling the next batch of products. Of course, the AOC component production tooling can also be dismantled after each production to overhaul each component.

[0052] Refer to Figure 8 , in some embodiments, a convex platform 822 is provided on the lower surface of the pressing plate 821. When performing step S230, the lower end surface of the convex platform 822 provided on the lower surface of the pressing plate 821 can abut against the upper surface of the connector 910, thereby realizing the pressing action of the pressing plate 821 on the connector 910.

[0053] The lower end surface of the pressing plate 821 is provided with a boss 822. When the pressing plate 821 rotates to the position closing the joint positioning groove 812, the boss 822 extends downward into the joint positioning groove 812, which can ensure the contact between the pressing plate 821 and the upper surface of the connector 910, so as to ensure the pressure provided to the connector 910 and prevent the connector 910 from jumping out of the joint positioning groove 812. It can be understood that, due to the boss 822 provided on the lower end surface of the pressing plate 821, for the connector 910 with a relatively thin thickness, the pressing plate 821 can also perform the pressing action.

[0054] In some embodiments, before performing step S710, first select a pressing plate 821 with a suitable height of the boss 822.

[0055] It can be understood that the height by which the boss 822 protrudes downward should be designed according to the thickness of the connector 910. When the pressing plate 821 rotates to the position closing the joint positioning groove 812, the distance between the lower end surface of the boss 822 and the bottom of the joint positioning groove 812 matches the thickness of the connector 910. In the embodiments provided with the spring 825, the distance between the lower end surface of the boss 822 and the bottom of the joint positioning groove 812 can be less than the thickness of the connector 910. When closing the joint positioning groove 812, the pressing plate 821 can move upward along the rotating shaft 823 by a certain distance, so that the spring 825 is further compressed, and the pressing of the boss 822 on the connector 910 can also be achieved. With such a setting, the anti-jumping plate 820 can be applicable to the pressing of connectors 910 with different thicknesses and is more universal.

[0056] In some embodiments, the production method of the AOC component is applied to the production and assembly of the multi-core AOC component product 900, such as a dual-core product, in which a single connector 910 is assembled corresponding to two ferrule cores. In the production tooling for producing the dual-core AOC component product 900, each joint positioning groove 812, two ferrule core positioning grooves 811, and two optical fiber positioning grooves together form a set of fixed-length structures. In the same set of fixed-length structures, the two ferrule core positioning grooves 811 are symmetrically arranged with respect to the central axis in the front-back direction of the joint positioning groove 812, and the two optical fiber positioning grooves are symmetrically arranged with respect to the central axis in the front-back direction of the joint positioning groove 812.

[0057] With such a setting, the ferrule cores are placed according to the positions of the ferrule core positioning grooves 811, and the optical fibers are placed according to the positions of the optical fiber positioning grooves, which can ensure that the two ferrule cores corresponding to the same connector 910 are symmetrically arranged with respect to the central axis of the connector 910, and the lengths of the optical fibers between the two ferrule cores and the connector 910 are equal. The two optical fibers used to connect the ferrule cores and the connector 910 are symmetrically arranged with respect to the central axis of the connector 910, improving the qualification rate of the product.

[0058] In some embodiments, referring to Figure 7 and Figure 11, the optical fiber positioning groove includes a first trend groove 813 and a second trend groove 814. The first trend groove 813 and the second trend groove 814 are respectively arranged to extend along the front-back direction. Among them, the first trend groove 813 is arranged on the front side of the second trend groove 814. The front end of the first trend groove 813 is communicatively connected with the ferrule positioning groove 811, and the rear end of the second trend groove 814 is communicatively connected with the connector positioning groove 812. Among the two optical fiber positioning grooves of the same set of fixed-length structures, the distance between the two first trend grooves 813 is greater than the distance between the two second trend grooves 814.

[0059] In some embodiments, step S400 includes step S410 and step S420. Refer to Figure 4 .

[0060] Step S410, place the front end of the optical fiber into the first trend groove 813 and connect the ferrule. With such a setting, a part of the optical fiber extending backward after being inserted into the ferrule is still in a state of extending along the front-back direction, avoiding the negative impact on the connection strength of the connection point caused by the bending and skewing of the optical fiber.

[0061] Step S420, place the rear end of the optical fiber into the second trend groove 814 and connect the connector 910. With such a setting, a part of the optical fiber extending forward after being inserted into the connector 910 is still in a state of extending along the front-back direction, avoiding the negative impact on the connection strength of the connection point caused by the bending and skewing of the optical fiber.

[0062] Since in the dual-core AOC component product 900, the two ferrules are respectively arranged on both sides of the connector 910, the two optical fibers for connecting the ferrule and the connector 910 need to gradually approach each other from one end of the ferrule to one end of the connector 910. By setting the first trend groove 813 and the second trend groove 814, the specific trend of the optical fiber can be restricted. In this embodiment, the first trend groove 813 and the second trend groove 814 are respectively arranged to extend along the front-back direction. At the position where the ferrule is connected to the optical fiber, by restricting through the first trend groove 813, the connection strength between the ferrule and the optical fiber can be improved, avoiding the situation where the connection between the ferrule and the optical fiber is unstable due to the twisting force of the optical fiber. At the position where the connector 910 is connected to the optical fiber, by restricting the trend of the optical fiber through the second trend groove 814, the connection strength between the optical fiber and the connector 910 can be improved, avoiding the situation where the connection between the connector 910 and the optical fiber is unstable due to the twisting force of the light.

[0063] It can be understood that the two optical fibers are arranged to approach each other from the first trend groove 813 to the second trend groove 814 at the position between the first trend groove 813 and the second trend groove 814.

[0064] In some embodiments, multiple sets of fixed-length structures are provided, and the multiple sets of fixed-length structures are arranged in the front-back direction. With the AOC component production tooling of this embodiment, multiple sets of AOC component products 900 can be placed simultaneously. Steps S100, S200, S300, S400, and S500 are repeated until the ferrule positioning grooves 811, connector positioning grooves 812, and optical fiber positioning grooves of the AOC component production tooling are filled, and then step S600 is performed. Multiple sets of AOC component products 900 can be baked and heated simultaneously, which is more conducive to mass-producing AOC component products 900 and reduces the energy consumption of multiple heating and baking processes.

[0065] In some embodiments, the AOC component production tooling further includes a placement plate 830. The front end of the placement plate 830 is connected to the rear end of the positioning plate 810. Before performing step S200, the cable portion of the optical cable is wound into a ring and placed on the placement plate 830.

[0066] It can be understood that the placement plate 830 is used to place the cable portion extending from the rear side of the connector 910, and can provide a supporting force for the cable portion of the optical cable, avoiding the tendency of the cable portion to sag downward, which causes the connector 910 to lift from the connector positioning groove 812. During actual use, the cable portion of the optical cable is wound into a ring and then placed on the optical cable placement plate 830, which can reduce the area occupied by the placement of the cable portion, and can also reduce the area of the placement plate 830, making the occupied space of the entire AOC component production tooling smaller, and more convenient for movement, transportation, packaging, and use.

[0067] In some embodiments, the AOC component production tooling further includes feet 840. The feet 840 are connected to the bottom surface of the placement plate 830 and are provided at the rear end of the placement plate 830, and can raise the rear end of the placement plate 830 to a certain height. Before performing step S600, the feet 840 are fixed below the placement plate 830, and the rear end of the placement plate 830 is raised, so that the placement plate 830 is in a state of being inclined upward from front to back.

[0068] It can be understood that during processing, when using glue to connect the optical fiber, ferrule, and connector 910, the position of the positioning plate 810 needs to be heated to bake and cure the glue. Raising the rear end of the placement plate 830 can keep the cable portion placed on the placement plate 830 away from the heat source, preventing problems such as shrinkage and damage of the cable portion due to heat.

[0069] It can be understood that the positioning plate 810 is made of a material with good thermal conductivity, while the placement plate 830 is made of a material with poor thermal conductivity. Moreover, feet 840 with a height that matches are required to ensure that the heat at the front and rear ends of the AOC component product 900 meets the requirements.

[0070] In this embodiment, the positioning plate 810 and the placement plate 830 are connected by screws, and the positioning plate 810 and the placement plate 830 are separable and detachable. With this arrangement, the operator can replace the positioning plate 810 or the placement plate 830 of different specifications according to the actual situation, making the AOC component production tooling more versatile. Moreover, the disassembled and separated AOC component production tooling is more conducive to storage and transportation.

[0071] In this embodiment, the foot pad 840 and the placement plate 830 are connected by screws, and the foot pad 840 and the placement plate 830 are separable and detachable. With this arrangement, the operator can replace the foot pads of different specifications according to the actual situation to achieve a better heating and baking effect.

[0072] In some embodiments, the AOC component production tooling further includes a heating plate 850. The heating plate 850 is disposed below the positioning plate 810 and is used to supply heat to the positioning plate 810. It can be understood that by providing the heating plate 850, the AOC component production tooling of this embodiment can achieve integrated production of high-precision fixed length and thermal curing, and can effectively, quickly and batch produce AOC component products.

[0073] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
