Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fiber end face polishing, in particular to an end face synchronous processing device and method for multi-core fiber manufacturing. BACKGROUND

[0002] As a new type of optical communication transmission medium, multi-core fiber contains multiple independent optical signal transmission channels in its interior, has the advantages of large transmission capacity and high integration, and has wide application prospects in high-speed data centers and next-generation optical communication networks.

[0003] The end face processing quality of multi-core fiber directly affects the transmission efficiency and coupling loss of optical signals, so high requirements are put forward for the end face processing technology. Multi-core fiber end face processing mainly includes three key procedures of cutting, polishing and cleaning, and the polishing procedure has the most significant influence on the end face roughness and flatness.

[0004] The existing multi-core fiber end face polishing mainly uses a semi-automatic polishing device. An operator first fixes the multi-core fiber in a special connector so that the end face is kept on the same plane, and then uses abrasive discs of different grits to perform rough polishing and fine polishing in turn.

[0005] After polishing is completed, the impurities remaining on the connector and the fiber need to be cleaned by air blowing to prevent the impurities from scratching the fiber end face during fine polishing. However, direct treatment by air blowing will inevitably cause the impurities to splash, and the impurities are easy to fall into the polishing disc of the next fine polishing station, causing secondary damage to the fiber end face in the subsequent polishing process, seriously affecting the end face quality, and simple air blowing is also difficult to completely remove the impurities embedded in the gap between the fibers.

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0033] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0034] Please refer to Figures 1-11 In the embodiments of the present application, a synchronous processing device for the end face of a multi-core optical fiber manufacturing device comprises: A machine table 1 and a receiving disc 2 fixed on the machine table 1, the receiving disc 2 is fixed with symmetrical grinding machines 3, and the grinding machines 3 are rotatably installed with grinding discs 4; Further comprising: A rotating and lifting assembly is arranged on the receiving disc 2, and a suction disc 9 for adsorbing a connector with an optical fiber inserted is connected to the rotating and lifting assembly; A pump cylinder 10 is fixed on the receiving disc 2 and is symmetrically arranged, a slit adsorption mechanism is arranged in the pump cylinder 10, a sealing disc 13 is connected to the slit adsorption mechanism, and a through groove 1301 is formed on the sealing disc 13; The one-way rotating mechanism is arranged on the slit adsorption mechanism, and can adjust the position and the conducting state of the conducting groove 1301 through the sealing disc 13 when the slit adsorption mechanism moves.

[0035] Specifically, when the end face of the multi-core optical fiber is processed, the end face of the optical fiber needs to be polished to ensure smoothness. To this end, a plurality of optical fibers can be inserted into a connector for fixing the optical fibers and making the end faces of the optical fibers in the same plane. Under the action of the suction disc 9, the connector can be adsorbed and fixed. Then, two abrasive discs of corresponding particle sizes are installed on the corresponding two polishing discs 4, and the two abrasive discs are used for rough polishing and fine polishing, respectively. At this time, the rotary lifting assembly works, and the connector is controlled to cooperate with the polishing disc 4 at the rough polishing position under the action of the suction disc 9. The end face of the optical fiber is rough polished under the action of the polishing disc 4. When the rough polishing is completed, the rotary lifting assembly controls the suction disc 9 to separate from the polishing disc 4, and moves to a position directly above the adjacent air cylinder 10, and controls the connector to cooperate with the slit adsorption mechanism. Under the action of the slit adsorption mechanism, the one-way rotating mechanism is driven to move, and the conducting groove 1301 is driven to move through the sealing disc 13, so as to adsorb the impurities adhering to the connector and the end face of the optical fiber in the circumferential direction. When the adsorption treatment is completed, the rotary lifting assembly controls the connector to move to the fine polishing position through the suction disc 9, and cooperates with the polishing disc 4 to perform fine polishing treatment. After fine polishing treatment, the connector is controlled to move to the position of the adjacent air cylinder 10 again, and the residual impurities after fine polishing are cleaned under the action of the slit adsorption mechanism and the one-way rotating mechanism.

[0037] Please refer to Figure 4In detail, four working positions can be divided on the receiving disc 2, which are rough polishing position, first cleaning position, fine polishing position and second cleaning position. The receiving rod 5 is fixed with a key, and the inner wall of the rotating plate 6 is formed with a key groove matched with the key. Under the cooperation of the key and the key groove, the rotating plate 6 can rotate with the receiving rod 5. In the initial state, the connector to be processed can be connected with the suction disc 9 located at the rough polishing position. At this time, under the action of the first cylinder 8, the lifting disc 7 is driven to move, so as to drive the rotating plate 6 to move towards the polishing disc 4 located at the rough polishing position through the first circular arc sliding groove 601, until the fiber end face on the connector is in abutting cooperation with the polishing disc 4. At this time, under the action of the polishing disc 4, the multiple fiber end faces are synchronously polished; When the rough polishing is completed, the connector and the fiber end face will have impurities remaining. At this time, the first cylinder 8 controls the connector to separate from the polishing disc 4, and at the same time, the receiving rod 5 drives the rotating plate 6 to rotate, so that the connector moves above the first cleaning position. The first cylinder 8 controls the connector to move to the cooperation position of the slit adsorption mechanism. Under the action of the slit adsorption mechanism and the one-way rotation mechanism, the sealing disc 13 is controlled to rotate, so that the through groove 1301 is opened, and negative pressure is formed in the pump cylinder 10. Under the action of the through groove 1301, the slit adsorption is formed, and the connector is adsorbed and cleaned in the circumferential direction; When the cleaning is completed, the first cylinder 8 controls the connector to separate from the slit adsorption mechanism, and at the same time, the receiving rod 5 rotates, so that the connector moves to the rough polishing position. Under the action of the first cylinder 8, the fiber is controlled to abut against the polishing disc 4 at this position through the connector. The polishing disc 4 will perform fine polishing on the fiber end face; When the fine polishing is completed, the rotating lifting assembly controls the connector to move to the second cleaning position, and under the action of the slit adsorption mechanism and the one-way rotation mechanism, the connector and the fiber are adsorbed and cleaned again. When the cleaning is completed, the connector can be taken out from the suction disc 9; When the connector moves from the rough polishing position to the first cleaning position, a new connector can be installed on the suction disc 9 located at the rough polishing position. In this way, the effect of continuously processing the fiber in multiple positions can be ensured.

[0041] Please refer to Figure 7Further, the outer circumferential wall of the pump cylinder 10 is provided with a balance pipe 26 and a discharge pipe 27, the discharge pipe 27 is connected with a collector for collecting impurities, the balance pipe 26 is located below the discharge pipe 27, and the pump cylinder 10 is further provided with a one-way valve connected with the balance pipe 26 and the discharge pipe 27 respectively, under the action of the one-way valve, when the through hole 1101 and the guide-through groove 1301 are in a blocked state, the gas in the pump cylinder 10 can only enter through the balance pipe 26 and be discharged through the discharge pipe 27, the top of the support disc 11 is provided with a sealing ring 12, when the connector abuts against the sealing ring 12, a sealed chamber is formed between the connector and the support disc 11, and the conduction state with the pump cylinder 10 can only be adjusted through the through hole 1101 and the guide-through groove 1301, the end part of the follower ring 17 is provided with two guide rails, namely a spiral guide rail 1701 and a vertical guide rail 1702, and the first and last ends of the spiral guide rail 1701 and the vertical guide rail 1702 are connected with each other; Please refer to Figure 9 When the limiting block 1801 moves along the spiral groove 2501 towards the direction close to the vertical groove 2502, the direction of rotation of the rotating rod 18 is defined as clockwise rotation, and vice versa, the end part of the limiting column 15 is provided in an arc shape, in the initial state, under the action of the second cylinder 23, the piston disc 24 is located at the end of the stroke close to the support disc 11, and the piston disc 24 is located between the balance pipe 26 and the discharge pipe 27, in this state, the limiting block 1801 is located at the end of the stroke away from the vertical groove 2502 on one side of the spiral groove 2501, the support column 21 is located at the connected position of the vertical guide rail 1702 and the spiral guide rail 1701, at this time, the maximum distance between the movable sleeve 20 and the limiting ring 19, and the elongation of the second spring 22 in the natural state is greater than the maximum distance between the movable sleeve 20 and the limiting ring 19, for this, the second spring 22 is in a pre-compressed state, and always provides a pushing force to the movable sleeve 20 in the direction away from the limiting ring 19, under the action of the vertical guide rail 1702 and the spiral guide rail 1701, the movable sleeve 20 drives the support column 21 to rotate clockwise, so that the follower ring 17 can be driven to rotate synchronously, in this state, the guide-through groove 1301 and the through hole 1101 are in a misaligned state, that is, the sealed chamber is in a sealed state, the limiting column 15 is inserted into the groove 1103, so that the distance between the fixed ring 1501 and the end part of the support sleeve 14 is maximum, and the elongation of the first spring 16 in the natural state is greater than the maximum distance between the fixed ring 1501 and the end part of the support sleeve 14, for this, the first spring 16 is in a pre-compressed state, and always provides a pushing force to the limiting column 15 in the direction of the groove 1103, under the action of the limiting column 15 and the groove 1103, the sealing disc 13 will not rotate when it is not subjected to a force; When the connector is polished, the connector and the optical fiber need to be cleaned to prevent impurities from remaining and scratching the end face of the optical fiber. At this time, under the action of the rotary lifting assembly, the connector is controlled to abut against the sealing ring 12, the second cylinder 23 works, the piston disc 24 is driven to move away from the support disc 11, and a negative pressure is formed in the pump cylinder 10. The piston disc 24 drives the guide groove to move synchronously through the fixed sleeve 25. Since the limiting block 1801 is embedded in the end of the spiral groove 2501 at the initial moment, at the initial stage of the downward movement of the piston disc 24, the limiting block 1801 interacts with the inclined surface of the spiral groove 2501 to generate a torque that drives the rotating rod 18 to rotate clockwise. This torque overcomes the static friction between the limiting column 15 and the groove 1103, forcing the rotating rod 18 to start rotating clockwise, so that the limiting column 15 is separated from the groove 1103 and slides along the second circular arc sliding groove 1102. The limiting column 15 also compresses the first spring 16 through the fixed ring 1501. The rotating rod 18 is fixed with a key, and the inner wall of the movable sleeve 20 is formed with a key groove matched with the key, so that the movable sleeve 20 can slide axially along the rotating rod 18 and can rotate with the rotating rod 18. For this reason, the rotating rod 18 will drive the movable sleeve 20 to rotate synchronously, and the support column 21 and the vertical guide rail 1702 control the follower ring 17 to rotate synchronously clockwise. Under the action of the follower ring 17, the sealing disc 13 rotates synchronously clockwise. Subsequently, when the sealing disc 13 rotates, the through groove 1301 is driven to move, so that the through groove 1301 is in communication with the through hole 1101. Since the size of the through groove 1301 is much smaller than the size of the through hole 1101, under the action of the through groove 1301, a narrow flow path is formed between the sealing chamber and the pump cylinder 10. At the same time, the continuous downward movement of the piston disc 24 causes the volume of the chamber above the piston disc 24 in the pump cylinder 10 to increase continuously. Due to the small size of the newly opened flow path, the resistance is huge, so that a continuous and strong negative pressure environment is rapidly generated in the upper chamber of the pump cylinder 10 and the sealed chamber of the connector end face. This negative pressure is sprayed out through the slit-shaped through groove 1301 to form a high-speed local scanning airflow, which can effectively strip and remove the polishing impurities attached to the end face of the optical fiber; During this process, the sealing disc 13 is in a state of continuous rotation, so that the position of the through groove 1301 changes continuously, thereby ensuring that the negative pressure adsorption can act on the connector and the end face of the optical fiber comprehensively.

[0042] When the limiting block 1801 disengages from the spiral groove 2501 and enters the vertical groove 2502, the sealing disc 13 rotates exactly one revolution. In this state, the guide groove 1301 is blocked again, and the impurities on the connector and optical fiber are cleaned. The limiting post 15 returns to the position of engaging with the groove 1103, and under the action of the first spring 16, the limiting post 15 re-enters the groove 1103 to lock the position of the sealing disc 13. In this way, the air path can be automatically cut off after a full revolution of cleaning, thus perfectly avoiding the possible secondary backflow of impurities after cleaning. At this time, the rotating lifting mechanism can control the connector to separate from the sealing ring 12 through the suction cup 9 and perform subsequent fine polishing operations. After the adsorption action is completed, the piston disc 24 continues to move downward, the limiting block 1801 slides in the vertical groove 2502, the rotating rod 18 and the sealing disc 13 remain stationary. When the piston disc 24 moves to below the balance tube 26, since the pump cylinder 10 is under negative pressure, the cleaned air connected by the balance tube 26 will enter the pump cylinder 10, so that the air pressure in the pump cylinder 10 is balanced with the external air pressure. Subsequently, the second cylinder 23 pushes the piston disc 24 upward to reset. In the initial reset phase, the limiting block 1801 slides within the vertical groove 2502, while the rotating rod 18 and sealing disc 13 remain stationary. When the piston disc 24 passes the balance pipe 26, positive pressure is created within the pump cylinder 10, thereby discharging the gas carrying impurities into the collector through the discharge pipe 27. When the limiting block 1801 disengages from the vertical groove 2502 and enters the spiral groove 2501, the rotating rod 18 rotates counterclockwise, driving the support column 21 to move via the movable sleeve 20. The support column 21 will slide along the spiral guide rail 1701, causing the movable sleeve 20 to gradually move towards the limiting ring 19 and compress the second spring 22. In this way, the position of the sealing disc 13 will not change during the entire reset process of the piston disc 24, ensuring that impurities in the pump cylinder 10 will not leak. When the limiting block 1801 returns to the initial position, the support column 21 disengages from the spiral guide rail 1701 and returns to the vertical guide rail 1702. The above steps are repeated to achieve the effect of slit adsorption and sealed discharge of impurities.

[0043] A method for synchronous end-face processing in multi-core optical fiber manufacturing includes the following steps: Step 1: The connector with the optical fiber installed is attracted by the suction cup 9. Under the action of the rotating lifting assembly, the suction cup 9 drives the connector to engage with the polishing disc 4, and the polishing disc 4 performs rough polishing on the optical fiber. Step 2: After rough polishing is completed, the rotary lifting assembly separates from the polishing disc 4 via the suction cup 9 control connector and moves to a position that engages with the slit suction mechanism; Step three: under the action of the slit adsorption mechanism, the one-way rotating mechanism moves to suck the impurities adhered on the connector into the pump cylinder 10 by negative pressure; Step four: when the connector cleaning is completed, the rotating lifting assembly moves the connector to the cooperation position with the next polishing disc 4 for fine polishing through the suction cup 9, and after the fine polishing is completed, the slit adsorption mechanism is used again to treat the impurities on the connector.
