Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber processing and manufacturing, and particularly relates to a method for processing an optical fiber and an optical fiber processing device. Background Art

[0002] In the existing optical fiber manufacturing technology, it is mostly necessary to sleave an adapter sleeve at the end of an optical fiber harness so that the optical fiber can be connected to a signal transmission device through the adapter sleeve.

[0003] In the existing optical fiber processing and manufacturing process, it is usually adopted to apply a connecting colloid to the end of the optical fiber core exposed from the insulating sleeve, and then sleave the adapter sleeve on the end of the optical fiber core, and use the connecting colloid to bond the end of the optical fiber core and the adapter sleeve to realize the fixed connection between the optical fiber harness and the adapter sleeve. However, due to the existence of gaps inside the optical fiber core, the connecting colloid easily enters the internal gaps of the entire optical fiber core along the optical fiber core, resulting in the hardening of the optical fiber harness due to the curing of the connecting colloid inside the optical fiber harness, affecting the bending radius of the optical fiber harness, being not convenient for the layout of the optical fiber harness inside the signal transmission device, and affecting the use of the optical fiber harness.

[0004] At present, it is mostly adopted to manually control the glue application length at the end of the optical fiber harness and control the glue application amount at the end of the optical fiber harness by scraping the glue to reduce the entry of the connecting colloid into the internal gaps of the optical fiber core. However, the processing procedures of manually controlling the glue application and scraping the glue have high technical requirements for production personnel, are difficult to process and have numerous procedures, and easily result in low production efficiency and low qualified product rate of the optical fiber.

[0018] After a first preset time, moving the fixing bracket out of the cleaning device.

[0019] Optionally, the fixing bracket is provided with a fixing plate. It is defined that the fixing plate has an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface. A plurality of fixing grooves are arranged at intervals along the length direction of the upper surface of the fixing plate, and the fixing grooves penetrate through the side surface of the fixing plate;

[0020] In the step of fixing the insulating sleeves sleeved with optical fiber cores to a fixing bracket, exposing the ends of the plurality of optical fiber cores on one side of the fixing bracket, and making the end faces of the plurality of insulating sleeves flush on one side of the fixing bracket, it includes:

[0021] Respectively threading the insulating sleeves sleeved with optical fiber cores through the plurality of fixing grooves and abutting against the inner wall of the groove of the fixing grooves, so that the ends of the optical fiber cores pass through the side surface of the fixing plate and are exposed on one side of the fixing plate;

Furthermore, when applying a connecting colloid to the end of the optical fiber core to bond the adapter sleeve, since the internal gap of the optical fiber core is blocked by the filling reagent, it can effectively prevent the connecting colloid from entering the optical fiber core through the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve, avoiding the hardening of the optical fiber harness caused by the connecting colloid curing on parts of the optical fiber harness other than the end, and ensuring that the optical fiber can be bent better in the signal transmission device. Furthermore, it effectively reduces the processing procedures such as scraping the colloid and controlling the colloid application amount at the end of the optical fiber core during the optical fiber processing, avoids damage to the optical fiber during the scraping process, reduces the processing difficulty of the optical fiber, and effectively improves the processing production efficiency and qualification rate of the optical fiber.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0051] Currently, manual control is mostly used to control the glue application length at the end of the optical fiber harness and to control the glue application amount at the end of the optical fiber harness by scraping the glue, so as to reduce the connection glue from entering the internal gap of the optical fiber core. However, the processing procedures of manual control of glue application and scraping require relatively high skills for production personnel, with large processing difficulties and numerous procedures, which easily lead to low production efficiency and qualified product rate of optical fibers. In view of the above problems, the present invention proposes a processing method for optical fibers.

[0052] An embodiment of the present invention provides a control method for a gene amplification instrument, referring to Figure 1 , Figure 1 is a schematic flow chart of the first embodiment of the processing method of the optical fiber of the present invention. The embodiments of the processing method of the optical fiber provided by the embodiments of the present application need to be noted that although the logical order is shown in the flow chart, in some cases, the steps shown or described may be executed in a different order from here. In this embodiment, the processing method of the optical fiber includes:

[0053] Step S10: Thread the optical fiber core through the insulating sleeve, and expose the end of the optical fiber core outside the end of the insulating sleeve;

[0054] It can be understood that the optical fiber core can be composed of a bundle of multiple optical fibers. Since the shape of the optical fiber is mostly circular, there is still a certain gap between the multiple optical fibers when they are bundled. At this time, when the optical fiber core is threaded into the insulating sleeve to form an optical fiber harness, there is still a certain internal gap in the optical fiber core. Under the action of the insulating sleeve, the insulating sleeve can be used to protect the optical fiber core. The insulating sleeve can be a glass fiber insulating tube or a heat shrinkable insulating tube, etc., so that the overall structure of the optical fiber harness is more stable and reliable. The optical fiber core can be directly threaded into the insulating sleeve from one end manually, or a threading tool can be used to more conveniently thread the optical fiber core into the insulating sleeve; and the length of the optical fiber core is greater than the length of the insulating sleeve, so that the end of the optical fiber core can be exposed outside the end of the insulating sleeve.

[0055] Step S30: Inject a filling reagent between the optical fiber core and the insulating sleeve, and make the filling reagent soak into the internal gap of the optical fiber core;

[0056] Among them, after the optical fiber core is threaded into the insulating sleeve, by injecting a filling reagent between the optical fiber core and the insulating sleeve, the filling reagent can soak into the internal gap of the optical fiber core, and then the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve can be effectively blocked by the filling reagent. Among them, the filling reagent can be glycerol or invisible glue, etc., and the filling reagent can be injected between the optical fiber core and the insulating sleeve through a small pinhole.

[0057] Step S50: Apply a connecting colloid to the end of the optical fiber core, and sleeved the adapter sleeve on the end of the optical fiber core so that the connecting colloid adheres to the end of the optical fiber core and the adapter sleeve.

[0058] It can be understood that the connecting colloid can be epoxy resin glue or thermosetting acrylic glue, etc. Since the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve are filled with a filling reagent, and the filling reagent cannot be miscible with the connecting colloid, the connecting colloid cannot enter the interior of the optical fiber bundle through the internal gap of the optical fiber core and the gap between the fiber core and the insulating sleeve. Therefore, the connecting colloid can only bond the adapter sleeve at the end of the optical fiber core, thus preventing the connecting colloid from curing inside the optical fiber bundle and hardening the optical fiber bundle, which affects the bending radius of the optical fiber bundle. Therefore, injecting the filling reagent between the optical fiber core and the insulating sleeve effectively reduces the processing procedures such as scraping glue in the optical fiber processing and production, prevents the optical fiber from being damaged during scraping glue, reduces the processing difficulty of the optical fiber, and improves the processing and production efficiency of the optical fiber.

[0059] The technical solution of the present invention passes through the optical fiber core through the insulating sleeve and injects a filling reagent between the optical fiber core and the insulating sleeve, and can use the filling reagent to fill the internal gap of the optical fiber core. Furthermore, when applying a connecting colloid to the end of the optical fiber core to bond the adapter sleeve, since the internal gap of the optical fiber core is blocked by the filling reagent, it can effectively prevent the connecting colloid from entering the optical fiber core through the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve, and avoid the part of the optical fiber bundle other than the end being cured with the connecting colloid and causing the optical fiber bundle to harden, ensuring that the optical fiber can be better bent in the signal transmission device. Furthermore, it effectively reduces the processing procedures such as scraping glue control and glue application amount at the end of the optical fiber core during the optical fiber processing, avoids damage to the optical fiber during the scraping glue process, reduces the processing difficulty of the optical fiber, and effectively improves the processing and production efficiency and qualification rate of the optical fiber.

[0060] Refer to Figure 2 , Figure 2 is a schematic flow chart of batch cleaning of the insulating sleeve tightly wrapping the optical fiber core and assembling it on the fixed bracket in an embodiment of the processing method of the optical fiber of the present invention. In this embodiment, after the step of injecting the filling reagent between the optical fiber core and the insulating sleeve and allowing the filling reagent to penetrate into the internal gap of the optical fiber core, and before the step of applying the connecting colloid to the end of the optical fiber core and sleeving the adapter sleeve on the end of the optical fiber core so that the connecting colloid adheres to the end of the optical fiber core and the adapter sleeve, it further includes:

[0061] Step S41: Heat the insulating sleeve to tightly wrap the optical fiber core.

[0062] It can be understood that when the insulating sleeve adopts a heat-shrinkable sleeve with functions of high-temperature shrinkage, soft flame retardancy, insulation and corrosion prevention, after injecting a filling reagent between the optical fiber core and the insulating sleeve, it is also necessary to perform treatments such as baking and heating on the insulating sleeve so that the insulating sleeve can tightly wrap the optical fiber core, and then the filling reagent can be better wrapped in the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve, so as to better isolate the connection colloid from entering the internal gap of the optical fiber core and the gap between the optical fiber core and the insulating sleeve, and prevent the connection colloid from solidifying inside the optical fiber bundle and hardening the optical fiber bundle.

[0063] Further, in this embodiment, after the step of heating the insulating sleeve to wrap the optical fiber core tightly, and before the steps of applying the connection colloid to the end of the optical fiber core and sleeving the adapter sleeve on the end of the optical fiber core to make the connection colloid adhere to the end of the optical fiber core and the adapter sleeve, it further includes:

[0064] Step S43: Fix the insulating sleeves sleeved with optical fiber cores to the fixing bracket, expose the ends of the multiple optical fiber cores on one side of the fixing bracket, and make the end faces of the multiple insulating sleeves flush with each other on one side of the fixing bracket;

[0065] It can be understood that under the action of the filling reagent, it can effectively prevent the connection colloid from entering the inside of the optical fiber bundle and reduce the processing procedures of the optical fiber. Since there is no need to manually perform operations such as scraping glue on each single optical fiber in sequence, multiple insulating sleeves sleeved with optical fiber cores can be fixed by the fixing bracket and processed simultaneously, which is beneficial to better realizing the batch processing of multiple insulating sleeves and further improving the processing and production efficiency of the optical fiber. Among them, the ends of the multiple optical fiber cores can be exposed on one side of the fixing bracket to facilitate processing the ends of the multiple optical fiber cores on one side of the fixing bracket. At the same time, making the end faces of the multiple insulating sleeves flush with each other on one side of the fixing bracket can also make the processing positions of the multiple optical fibers consistent, better control the consistency of the processed optical fiber products, and ensure a higher qualification rate of the processed optical fiber.

[0066] Step S45: Clean the filling reagent on the surface of the end of the optical fiber core.

[0067] It can be understood that after injecting a filling reagent between the optical fiber core and the insulating sleeve, there is a certain probability that the filling reagent will flow along the optical fiber core to the surface of the end of the optical fiber core. Since the filling reagent is immiscible with the connecting colloid, the filling reagent exposed on the surface of the end of the optical fiber core has a certain probability of affecting the bonding of the connecting colloid to the optical fiber core and the adapter sleeve. By cleaning the end of the optical fiber core after the insulating sleeve tightly wraps the optical fiber core, the filling reagent on the surface of the end of the optical fiber core can be effectively cleaned with anhydrous ethanol, so that the connecting colloid can more stably bond the end of the optical fiber core and the adapter sleeve, making the structure of the processed optical fiber more stable and reliable, and ensuring the normal use of the optical fiber.

[0068] Referring to Figure 3 , Figure 3 FIG. is a schematic flow chart of cleaning the filling reagent at the end of the optical fiber core in an embodiment of the processing method of the optical fiber of the present invention. In this embodiment, the steps of cleaning the filling reagent at the end of the optical fiber core include:

[0069] Step S451: Move the fixing bracket to the cleaning device and insert the ends of multiple optical fiber cores into the cleaning pool of the cleaning device;

[0070] It can be understood that under the action of the fixing bracket, multiple optical fibers can be placed in the cleaning device for cleaning by using the fixing bracket. At this time, under the action of the end faces of multiple insulating sleeves being flush with one side of the fixing bracket, the depths of the ends of multiple optical fiber cores in the cleaning pool can be kept consistent, effectively reducing the cleaning of the filling reagent between the optical fiber core and the insulating sleeve in the cleaning pool, ensuring that the filling reagent isolates the connecting colloid from entering the interior of the optical fiber bundle, better realizing the batch processing of optical fibers, and further improving the processing efficiency of optical fibers.

[0071] Step S453: Start the cleaning device to enable the cleaning device to clean the filling reagent on the surfaces of the ends of multiple optical fiber cores to be cleaned;

[0072] The cleaning device can be an ultrasonic cleaning device. At this time, by starting the cleaning device, the filling reagent on the surface of the end of the optical fiber core can be cleaned by ultrasonic waves in the cleaning pool, so that the surface of the end of the optical fiber core can achieve a better cleaning effect, facilitating the bonding of the connecting colloid.

[0073] Step S455: After a first preset time, move the fixing bracket out of the cleaning device.

[0074] It can be understood that the first preset time can be the preset cleaning time inside the cleaning device. By cleaning the end of the optical fiber core in the cleaning pool and then cleaning the end of the optical fiber core at the fixed bracket after the first preset time, the cleaning device can ensure that the end of the optical fiber core has sufficient cleaning time, so that the end of the optical fiber core can be cleaned more thoroughly, further ensuring the processing reliability of the optical fiber.

[0075] Refer to Figure 4 , Figure 4 FIG. is a schematic flow chart of a fixed bracket for fixing an optical fiber harness according to an embodiment of the method for processing an optical fiber of the present invention. In this embodiment, the fixed bracket is provided with a fixing plate, and it is defined that the fixing plate has an upper surface, a lower surface, and side surfaces connecting the upper surface and the lower surface. A plurality of fixing grooves are arranged at intervals along the length direction of the upper surface of the fixing plate, and the fixing grooves penetrate through the side surfaces of the fixing plate. In the step of fixing a plurality of insulating sleeves sleeved with optical fiber cores to the fixed bracket, exposing the ends of the plurality of optical fiber cores on one side of the fixed bracket, and making the end faces of the plurality of insulating sleeves flush with one side of the fixed bracket, it includes:

[0076] Step S431: Respectively pass a plurality of insulating sleeves sleeved with optical fiber cores through the plurality of fixing grooves and abut against the inner wall of the groove of the fixing groove, so that the ends of the optical fiber cores pass through the side surface of the fixing plate and are exposed on one side of the fixing plate;

[0077] It can be understood that by arranging a plurality of fixing grooves on the fixing plate to limit and fix the insulating sleeves sleeved with optical fiber cores, the optical fiber harness can be fixed on the fixing plate more stably and reliably for processing, ensuring the reliability of processing a plurality of optical fiber harnesses by using the fixing plate, and further improving the reliability and qualification rate of optical fiber processing. At this time, since the fixing groove penetrates through the side surface of the fixing plate, the end of the optical fiber core can pass through the side surface of the fixing plate and be exposed on one side of the fixing plate, so as to facilitate better cleaning, gluing, and sleeving of the transfer sleeve and other processes on the end of the optical fiber core, improving the convenience of optical fiber processing and further improving the production efficiency of optical fibers.

[0078] Step S433: Control the length of the insulating sleeve passing through the fixing groove so that the end faces of the plurality of insulating sleeves are flush with one side of the fixed bracket.

[0079] It can be understood that since the fixing groove only plays a role in limiting and fixing the optical fiber harness, by pulling the insulating sleeve to control the length of each insulating sleeve passing through the fixing groove at this time, the end faces of the plurality of insulating sleeves can be kept flush on one side of the fixed bracket, so that the processing positions of the plurality of optical fiber harnesses are kept consistent, ensuring the batch processing qualification rate and finished product consistency of the optical fiber.

[0080] Further, referring to Figure 5 , Figure 5 which is a schematic flow chart of applying glue to the end of the optical fiber core and sleeving a transition sleeve in an embodiment of the processing method of the optical fiber of the present invention. In this embodiment, the bottom wall of the fixing groove is inclined towards the lower surface of the fixing plate, so that the end of the optical fiber core inclines downward and passes through the side surface of the fixing plate. In the steps of applying a connecting colloid to the end of the optical fiber core and sleeving a transition sleeve on the end of the optical fiber core, it includes:

[0081] Step S51: Fill the connecting colloid into the glue mixing tray;

[0082] Step S53: Connect the glue mixing tray to the side surface of the fixing plate and place it below the end of the optical fiber core, so that the end of the optical fiber core inclines downward and inserts into the glue mixing tray;

[0083] Step S55: Use a glue brushing tool to apply the connecting colloid to the surface of the end of the optical fiber core;

[0084] It can be understood that since the optical fiber bundle abuts against the bottom wall of the fixing groove in the fixing groove, at this time, the end of the optical fiber core can incline downward along the inclination of the bottom wall of the fixing groove and pass through the side surface of the fixing plate. At this time, placing the glue mixing tray carrying the connecting colloid on the side surface of the fixing plate can make the end of the optical fiber core incline downward and insert into the glue mixing tray. Then, using a brush or a glue applicator stick to apply the connecting colloid in the glue mixing tray to the end of the optical fiber core can make the connecting colloid slide obliquely downward along the end of the optical fiber core due to the action of gravity, effectively preventing the connecting colloid from flowing back into the interior of the optical fiber bundle. At the same time, due to gravity, the connecting colloid flows and is applied to the end of the optical fiber core, so that the connecting colloid can flow more evenly over the entire end of the optical fiber core and prevent over-application of glue on the surface of the end of the optical fiber core, further reducing the optical fiber processing difficulty and processing procedures, and better improving the optical fiber processing production efficiency.

[0085] Step S57: Successively sleeved transition sleeves on the ends of multiple optical fiber cores exposed on one side of the fixing bracket.

[0086] After applying glue to the optical fiber bundle, the glue mixing tray can be removed from the side surface of the fixing plate. At this time, the transition sleeves can be successively sleeved on the ends of multiple optical fiber cores, so that the connecting colloid smeared on the surface of the optical fiber core can be placed between the end of the optical fiber core and the inner tube wall of the transition sleeve, so that the connecting colloid can bond the end of the optical fiber core and the transition sleeve.

[0087] Further, in this embodiment, after the step of applying the connecting colloid to the end surface of the optical fiber core using a glue application tool and before the step of successively sleeving the end portions of multiple optical fiber cores exposed on one side of the fixing bracket with adapter sleeves, the following steps are further included:

[0088] Step S56: Apply the connecting colloid to the outer peripheral side of the end of the insulating sleeve.

[0089] It can be understood that when the adapter sleeve is sleeved on the end of the optical fiber core, one end of the adapter sleeve can be sleeved on the insulating sleeve, so that the adapter sleeve can be more stably connected to the end of the optical fiber core wrapped by the optical fiber bundle, realizing a more stable and reliable connection. Therefore, while applying glue to the end of the optical fiber core, the connecting colloid can be applied to the outer peripheral side of the end of the insulating sleeve, so that the connecting colloid can bond the end of the insulating sleeve and the adapter sleeve, further improving the processing reliability of the optical fiber, reducing the phenomenon of the adapter sleeve falling off during the use of the optical fiber, and ensuring the normal use of the optical fiber.

[0090] Further, in this embodiment, after the step of successively sleeving the end portions of multiple optical fiber cores exposed on one side of the fixing bracket with adapter sleeves and before the step of moving the fixing bracket to the curing device, the following steps are further included:

[0091] Step S59: Wipe the outer surface of the adapter sleeve with a cleaning reagent to remove the connecting colloid attached to the outer surface of the adapter sleeve.

[0092] It can be understood that the adapter sleeve can be connected to the optical fiber core by directly sleeving the end of the optical fiber core. At this time, the connecting colloid is applied to the end surface of the optical fiber core, which easily causes the connecting colloid to overflow to the outer surface of the adapter sleeve during the sleeving process of the adapter sleeve. Therefore, after the adapter sleeve is sleeved on the end of the optical fiber core, the outer surface of the adapter sleeve can be wiped with a cotton cloth or cotton ball adsorbed with ethanol to wipe off the connecting colloid on the outer surface of the adapter sleeve, preventing the connecting colloid from curing on the outer surface of the adapter sleeve and affecting the connection of the optical fiber, further ensuring the structural reliability of the processed optical fiber and improving the qualified rate of the optical fiber products.

[0093] Refer to Figure 6 , Figure 6 which is a schematic flow chart of curing the connecting colloid in the optical fiber bundle using a curing device in an embodiment of the processing method of the optical fiber of the present invention. In this embodiment, after the step of successively sleeving the end portions of multiple optical fiber cores exposed on one side of the fixing bracket with adapter sleeves, the following steps are further included:

[0094] Step S61: Move the fixing bracket to the curing device;

[0095] Step S63: Start the curing device to cure the connecting colloid between the end of the optical fiber core and the adapter sleeve;

[0096] It can be understood that the curing device can be a hot oven or a heating device, etc., and the connecting colloid can adopt a thermosetting colloid structure. After applying glue to the end of the optical fiber core and combining it with the adapter sleeve, move the fixing bracket into the curing device and start the fixing device to raise the temperature inside the fixing device to the curing temperature of the connecting colloid. The curing device can be used to heat multiple optical fiber bundles fixed on the fixing bracket, so that the connecting colloid bonded between the end of the optical fiber core and the adapter sleeve can be cured faster under the action of high temperature, thereby further improving the processing and production efficiency of the optical fiber. Among them, under the action of the fixing bracket, batch processing of multiple optical fibers can be effectively realized, further reducing the processing procedures of the optical fiber and improving the processing efficiency of the optical fiber.
