Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical fiber ring winding, in particular to a pressure controllable guide wire pressure foot rod device for optical fiber ring winding. BACKGROUND

[0002] The current multi-pole ring winding machine cannot arrange the optical fiber well during the actual winding process because the guide wheel is far away from the optical fiber ring and the winding tension is small during the winding process. A guide wire pressure foot rod is used to assist the fiber arrangement during winding. The existing pressure foot rod adjusts the fiber arrangement pressure by the experience of the winding personnel. If the pressure is too small, the fiber arrangement effect is not good, and if the pressure is too large, the performance of the optical fiber ring will be affected.

[0003] One theoretical way is to correspond the fiber arrangement position and the pressing force one by one according to pre-trial, to control the position accurately through a servo linear module, and to install a pressure sensor at the pressure foot rod to feedback the actual force and correct the position. This way has high requirements for servo control and is difficult to be applied in practice. SUMMARY

DETAILED DESCRIPTION

[0032] Example 1:

[0033] As Figures 1-14 In the present application, a pressure controllable fiber guiding device for fiber ring winding includes a first linear guide rail module 1, the first linear guide rail module 1 is provided with a movable first sliding table 101, the first sliding table 101 is provided with a second linear guide rail module 2, the second linear guide rail module 2 is provided with a movable second sliding table 201, the moving directions of the first sliding table 101 and the second sliding table 201 are perpendicular, the second sliding table 201 is provided with a cross arm 3, the end of the cross arm 3 is provided with a fiber guiding assembly 6 with a pressure regulating mechanism 5, the fiber guiding assembly 6 is provided with a fiber rod 601, the fiber rod 601 is tightly attached to the outer wall of the fiber.

[0034] The first linear guide rail module 1 and the second linear guide rail module 2 are screw guide rail modules, the sliding tables are slidably connected with the guide rails through sliding blocks, one end of the screw rod is provided with a servo motor to drive the sliding table to move.

[0035] The first linear guide module 1 and the second linear guide module 2 mainly function to drive the optical fiber pushing rod 601 to move horizontally and vertically with the increase of the number of turns and layers of the optical fiber on the optical fiber coil 7 during fiber arranging.

[0036] The fiber guiding assembly 6 is connected with the horizontal arm 3 through the pressure adjusting mechanism 5, and the pressure adjusting mechanism 5 can adjust and monitor the normal pressure and side pressure of the optical fiber pushing rod 601 pressing against the side wall of the optical fiber.

[0037] The conventional way is to install a vertical spring device at the optical fiber guiding pressure foot rod, and a horizontal spring is installed between the mounting plate of the optical fiber guiding pressure foot rod and the driving mechanism, but such a way can only be used for optical fibers with specific diameters, and when the elastic force exceeds the force required by the optical fiber arranging process, the spring needs to be manually replaced, which is time-consuming and laborious.

[0038] Therefore, in the preferred scheme, the pressure adjusting mechanism 5 comprises a base frame, a first electromagnetic repulsion assembly and a second electromagnetic repulsion assembly arranged perpendicularly on the base frame, the fiber guiding assembly 6 comprises a sliding block 602, the sliding block 602 is in sliding connection with the base frame, the sliding block 602 is provided with a guide sleeve 603, the optical fiber pushing rod 601 is in sliding sleeve connection with the guide sleeve 603, the sliding direction of the sliding block 602 is perpendicular to the optical fiber pushing rod 601, one end of the optical fiber pushing rod 601 close to the first floating magnetic core 503 is connected with a first magnet 509, the first electromagnetic repulsion assembly is aligned with the first magnet 509, and the second electromagnetic repulsion assembly is aligned with a second magnet 510.

[0039] In the preferred scheme, the base frame is provided with a first limiting sleeve 501 and a second limiting sleeve 505, the first electromagnetic repulsion assembly comprises a hollow frame-shaped first coil 502, the first coil 502 is arranged in the first limiting sleeve 501, the first coil 502 is provided with the first floating magnetic core 503, the second electromagnetic repulsion assembly comprises a hollow frame-shaped second coil 506, the second coil 506 is arranged in the second limiting sleeve 505, the second coil 506 is provided with the second floating magnetic core 507, the moving direction of the first floating magnetic core 503 is perpendicular to the moving direction of the second floating magnetic core 507, one side of the first floating magnetic core 503 is provided with a first pressure sensor 504, the first pressure sensor 504 is tightly attached to the first floating magnetic core 503, the optical fiber pushing rod 601 is arranged on the other side of the first floating magnetic core 503, one side of the second floating magnetic core 507 is provided with a second pressure sensor 508, the second pressure sensor 508 is tightly attached to the second floating magnetic core 507, the sliding block 602 is arranged on the other side of the second floating magnetic core 507, and one end of the sliding block 602 close to the second floating magnetic core 507 is provided with the second magnet 510.

[0040] The first coil 502 and the second coil 506 are rectangular frames or cylindrical frames with multiple turns of coils, wrapping but not pressing the outer wall of the first floating magnetic core 503 and the second floating magnetic core 507, which are made of soft magnetic material. When the first coil 502 and the second coil 506 are energized, each coil and magnetic core generates repulsion force on the first magnet 509 and the second magnet 510. Since the other end of each magnetic core is pressed by the first pressure sensor 504 and the second pressure sensor 508, the value of the repulsion force transmitted can be detected.

[0041] The base frame is used to connect with the cross arm 3, and limiting blocks are arranged near both ends of the first floating magnetic core 503 and the second floating magnetic core 507, so that the first floating magnetic core 503 and the second floating magnetic core 507 can move slightly but will not fall out. The base frame is provided with double guide rods, and the sliding block 602 is provided with a guide sleeve and can slide along the guide rods.

[0042] The first electromagnetic repulsion assembly and the second electromagnetic repulsion assembly can control the forward and lateral pressure during fiber arranging, respectively. Compared with the traditional spring device for maintaining the fiber arranging pressure, the current scheme can change the current at any time to adjust the pressure. When producing different fiber rings, the spring does not need to be disassembled, and the current intensity can be directly adjusted to match the fiber arranging pressure to the current fiber process.

[0043] In the preferred scheme, the rotating table 4 is further provided with a fixed plate 401 connected with the cross arm 3, and the base frame of the pressure regulating mechanism 5 is further provided with a first limiting sleeve 501 in sleeved connection with the fixed plate 401.

[0044] The fixed plate 401 is provided with a steering drive motor 402, and a synchronous belt speed reduction mechanism 403 is sleeved between the shaft end of the steering drive motor 402 and the base frame rotating shaft 511. The steering drive motor 402 drives the pressure regulating mechanism 5 to rotate around the base frame rotating shaft 511, and the central shaft of the fiber poking rod 601 is coaxial with the central shaft of the base frame rotating shaft 511.

[0045] The rotating table 4 mainly changes the fiber arranging posture adaptively according to the different placing postures of the fiber ring 7. Since there are tensioning mechanisms, driving devices and the like installed at the position of the fiber ring 7 in actual use, the components of the pressure regulating mechanism 5 may interfere with each other in position, and therefore the angle of the pressure regulating mechanism 5 and the orientation of the fiber poking rod 601 may need to be adjusted.

[0046] In the preferred scheme, the fiber guiding assembly 6 further includes a clamping block 605, one end of which is provided with a guide rod 606 in sleeved connection with the sliding block 602.

[0047] In the preferred scheme, the fiber poking rod 601 is provided with a poking rod head 604 at the end thereof, which is detachably connected with the fiber poking rod 601.

[0048] The sliding block 602 is provided with a copper or ceramic bushing, and the optical fiber pushing rod 601 and the guide rod 606 are sleeved with the bushing.

[0049] The upper end of the pushing rod head 604 is inserted into or screwed with the lower end of the optical fiber pushing rod 601, and the joint is tightly screwed with a jack screw.

[0050] In the preferred embodiment, the end of the optical fiber pushing rod 601 is provided with a plurality of optical fiber pushing grooves with different sizes.

[0051] The width and depth of the same groove are the same, and the optical fiber pushing grooves of the optical fiber pushing rod 601 include a first pushing groove 609, a second pushing groove 610, a third pushing groove 611 and a fourth pushing groove 612, which are arranged at 90 degrees and the sizes of the grooves decrease in turn. Under the premise that the pressure regulating mechanism 5 does not interfere with other mechanisms, when the pressure regulating mechanism 5 rotates as a whole, different grooves can be matched with optical fibers of different diameters, and automatic switching can be realized without replacing the pushing rod head.

[0052] In the preferred embodiment, the optical fiber pushing rod 601 is sleeved with an expansion sleeve 607, and the expansion sleeve 607 is provided with optical fiber pushing grooves at the end thereof, and the optical fiber pushing rod 601 can be retracted into the expansion sleeve 607.

[0053] After the optical fiber pushing grooves at the end of the optical fiber pushing rod 601 are retracted into the expansion sleeve 607, the optical fiber pushing grooves at the end of the expansion sleeve 607 are in working condition for fiber arranging operation.

[0054] In the preferred embodiment, the optical fiber pushing grooves of the expansion sleeve 607 are at least two, the optical fiber pushing rod 601 is provided with a first threaded section 615, the first threaded section 615 is screwed with the expansion sleeve 607, the expansion sleeve 607 is provided with a second threaded section 617, the guide sleeve 603 is provided with a slidable sliding sleeve 608, the first magnet 509 is arranged at the end of the sliding sleeve 608, the expansion sleeve 607 is screwed with the inner wall of the sliding sleeve 608 through the second threaded section 617, the end of the sliding sleeve 608 away from the first magnet 509 is provided with a second lug 619, the outer wall of the expansion sleeve 607 is provided with a first lug 618, and a tension spring 620 is further arranged, the first lug 618 and the second lug 619 are connected through the tension spring 620, one end of the expansion sleeve 607 is provided with an end stop sleeve 616, and the first threaded section 615 is inserted into or screwed with the end stop sleeve 616 to make the expansion sleeve 607 rotate.

[0055] The optical fiber pushing grooves of the expansion sleeve 607 can be provided with a fifth pushing groove 613 and a sixth pushing groove 614, which are arranged back to back.

[0056] The outer wall of the sliding sleeve 608 is provided with a guide groove along the length direction, and the inner wall of the guide sleeve 603 is provided with a guide protrusion matched with the guide groove, so that the sliding sleeve 608 can slide but cannot rotate.

[0057] In a preferred solution, the sliding sleeve 608 is provided with an open half cutaway 622, the sliding block 602 is provided with a transmission assembly base plate 804, one end of the transmission assembly base plate 804 is provided with a C-shaped hole 806 and extends into the open half cutaway 622, a sliding bushing 805 is arranged at the C-shaped hole 806, a rotatable first transmission wheel 802 is sleeved on the sliding bushing 805, the optical fiber shifting rod 601 is further provided with a driving rod portion 621, the driving rod portion 621 is sleeved with the first transmission wheel 802 in a sliding manner, the sliding block 602 is further provided with a shifting rod driving motor 8, a second transmission wheel 803 is arranged at the shaft end of the shifting rod driving motor 8, and a transmission belt 801 is further arranged, and the first transmission wheel 802 is in transmission with the second transmission wheel 803 through the transmission belt 801.

[0058] The first transmission wheel 802 and the second transmission wheel 803 adopt a synchronous belt or a chain wheel. The outer wall of the driving rod portion 621 is provided with a guide groove in the length direction, and the inner wall of the first transmission wheel 802 is provided with a guide protrusion matched with the guide groove, so that the driving rod portion 621 can slide relative to the first transmission wheel 802 but cannot rotate relative to the first transmission wheel 802, thereby achieving dynamic transmission.

[0059] When the device is relatively compact as a whole, part of the mechanism interferes with other existing mechanisms when the pressure regulating mechanism 5 rotates. At this time, the second transmission wheel 803 is driven to rotate by the operation of the shifting rod driving motor 8, the second transmission wheel 803 drives the first transmission wheel 802 to rotate, and the second transmission wheel 803 drives the driving rod portion 621 to rotate. Since the tension spring 620 is tensioned to make the expansion sleeve rod 607 unable to rotate freely, only the driving rod portion 621 drives the optical fiber shifting rod 601 at the lower end to rotate and stretch and contract. Since the pitch interval is small, even if the optical fiber shifting rod 601 rotates through four shifting grooves, the optical fiber shifting rod 601 will not stretch and contract too much, and the overall length will not affect the fiber arrangement. If the driving rod portion 621 continues to rotate, the optical fiber shifting rod 601 gradually retracts into the expansion sleeve rod 607, and at this time, one of the fifth shifting groove 613 and the sixth shifting groove 614 serves as the shifting groove position for fiber arrangement. Continue to rotate the driving rod portion 621, when the second threaded section 617 reaches the limit position and abuts against the end stop sleeve 616, the expansion sleeve rod 607 is driven to rotate and helically ascend, and the expansion sleeve rod 607 rotates by half a circle to make the other one of the fifth shifting groove 613 and the sixth shifting groove 614 serve as the shifting groove for fiber arrangement, and at this time, the tension spring 620 is stretched.

[0060] A single shifting rod driving motor 8 can drive two shifting rods to automatically switch six groove positions, which can adapt to six types of optical fiber diameters, and greatly improves the adaptability of the shifting rod to the diameter of the optical fiber.

[0061] When the shifting rod driving motor 8 reversely rotates, the expansion sleeve rod 607 is reversely rotated and reset under the elastic force of the tension spring 620. After the expansion sleeve rod 607 is reset, the shifting rod driving motor 8 continues to rotate, and the optical fiber shifting rod 601 extends from the expansion sleeve rod 607.

[0065] The replaceable presser is adjusted to the appropriate position of the optical fiber ring by the servo motor driving the linear guide rail module and the servo motor driving the linear guide rail module through the speed reducer, so that the presser is pressed to the tangent point of the optical fiber entering the optical fiber ring. When the presser support does not trigger the proximity sensor, the upper limit light point sensor and the lower limit photoelectric sensor, the position of the fiber arranging presser is in the adjustable area. At this time, the coil and the coil are energized. By monitoring the value of the pressure sensor, the current of the coil is adjusted to change the acting force between the soft magnetic material magnetic core and the strong magnet to control the downward pressure of the replaceable presser. By monitoring the value of the pressure sensor, the current of the coil is adjusted to change the acting force between the soft magnetic material magnetic core and the strong magnet to control the lateral pressure of the replaceable presser. The direction of the fiber arranging can be changed by the stepping motor driving the rotating platform, and the direction of the fiber arranging is detected by the proximity switch.
