Description

Technical Field

[0001] This invention relates to the field of optical fiber end-of-line processing technology, specifically to an end-of-line processing device for optical fibers. Background Technology

[0002] The fiber optic cable ends need to be installed onto the surface of the network equipment via a mating connector. Before mating with the connector, the coating on the fiber optic cable surface usually needs to be stripped.

[0003] Patent publication number CN114114541B relates to an optical fiber stripper that prevents the fiber core from breaking, belonging to the field of optical fibers. The optical fiber stripper includes an upper base, a lower base, a cutting unit, a support unit, and a limiting unit. The rear ends of the upper and lower bases are rotatably connected by a torsion spring. It also includes a moving unit. The cutting unit includes a fixed blade and a moving blade. In a free state, the fixed blade and the moving blade abut against each other and form a triangular cutting blade. The fixed blade is fixedly connected to the upper base. The moving blade is fixedly connected to the moving unit, and the moving unit is slidably connected to the upper base. The moving unit can move along the length of the upper base. It can achieve parallel cutting of the optical fiber by the upper and lower bases, and then the sliding moving unit causes the excess outer sheath covering the inner core to be torn off along a straight line, effectively avoiding the problem of the inner core being broken due to manually unscrewing the excess outer sheath. It can also be operated with one hand, making it simple and convenient.

[0004] In the aforementioned patent, the cutting blade is divided into a fixed blade and a moving blade. When the upper substrate and the lower substrate are parallel, the lower end of the moving blade is higher than the upper edge of the inner core and lower than the upper edge of the outer sheath. The moving blade is fixedly connected to the moving unit, which can move along the length of the upper substrate. When the upper substrate rotates towards the lower substrate, after cutting the optical fiber, the finger can press the resistance block and move it to the rear, so that the moving blade pulls the residual sheath in a straight line, causing the residual sheath to break under stress in a straight line. There is no need to twist or break the optical fiber, which effectively ensures that the inner core is not bent at an angle and effectively avoids the risk of the inner core being bent and broken. However, it is difficult to align the optical fiber when it is put into the cutting blade. Manual alignment is prone to uneven force, which can cause the optical fiber to bend and affect the stripping effect. Moreover, the hand-held working method is prone to shaking during the stripping process, which affects the stability of the work. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an end-of-optical fiber processing device that solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an end-of-fiber processing device, comprising a base and a cover, the cover being rotatably mounted on the surface of the base, a heating seat being mounted on the surface of the base, a pressure cover being rotatably mounted on the surface of the heating seat, a slide seat being slidably mounted on the surface of the base, a clamping cover being slidably mounted on the top of the slide seat, a control console being provided on the surface of the base, and a plurality of connecting rods being rotatably mounted on the bottom of the clamping cover, a first torsion spring being provided between the connecting rods and the clamping cover, and a push bar being provided at the bottom of the connecting rods. When the clamping cover moves downward, it drives the push bar to move. When the push bar contacts the optical fiber, it is blocked by the optical fiber. If the clamping cover continues to move, it will squeeze the connecting rod to deflect. When the connecting rod rotates, it pushes the push bar to move, and the push bar drives the optical fiber to move towards the baffle. When the optical fiber contacts the surface of the baffle... The movement will stop, and the alignment of the optical fibers will be completed after all the optical fibers have contacted the baffle, ensuring that each optical fiber is the same length when it enters the heating seat, and that the exposed core length is uniform after stripping, which facilitates the subsequent connection of optical fibers and connectors. A first elastic telescopic rod is slidably installed on the right side of the slide, and a baffle is fixedly installed on the free end of the first elastic telescopic rod. The baffle needs to be able to slide up and down and slide left and right at the same time. The baffle and the slide are connected by the first elastic telescopic rod, and the elastic force of the first elastic telescopic rod will cause the baffle to return to its original position. A sliding rod is provided on the top of the baffle, and a second elastic telescopic rod is provided on the side of the heating seat near the slide. A first spring is provided between the sliding rod and the baffle. A pressure plate is fixedly installed on the right side of the clamp cover. The clamp cover moves downward, causing the pressure plate to press down and push the baffle downward.

[0007] According to the above technical solution, a sleeve frame is provided between the connecting rod and the push bar. A guide rail is provided on the surface of the sleeve frame. One end of the guide rail is bent. The sleeve frame is hinged to the bottom of the connecting rod. The push bar is slidably installed in the guide rail. When all the optical fibers are aligned, the push bar no longer pushes the optical fibers to move. The reaction force of the optical fibers on the push bar causes the push bar to move in the guide rail and be lifted upward under the guidance of the bend in the guide rail, so that the sleeve frame contacts the surface of the optical fiber. As the connecting rod continues to push the sleeve frame to move, the inner wall of the sleeve frame slides along the surface of the optical fiber to straighten the optical fiber, so as to avoid the bending of the optical fiber surface during the core stripping process from affecting the core stripping effect. An elastic element is provided between the push bar and the guide rail.

[0008] According to the above technical solution, the connecting rod is inclined and a second torsion spring is provided between it and the clamp. The connecting rod is initially inclined and will deflect in the inclined direction when squeezed by the clamp. The elastic force of the second torsion spring will reset the connecting rod.

[0009] According to the above technical solution, a backing plate is sleeved inside the baffle, and a slider is provided at the bottom of the backing plate. An inclined surface is provided on the side of the slider near the heating seat. An extension plate is fixedly installed on the side of the heating seat near the slider. A push plate is fixedly installed on the surface of the extension plate. The push plate presses the inclined surface at the bottom of the slider, causing the slider to move upward and lift the backing plate. After the slider moves upward, it lifts the backing plate from inside the baffle, so that the top of the backing plate is pressed against the edge of the fiber stripping area. When the coating layer on the surface of the stripping area melts, it guides the melted coating layer to collapse in the opposite direction of the stress on the backing plate, ensuring the flatness of the coating layer cut surface and facilitating the subsequent splicing of optical fibers.

[0010] According to the above technical solution, the slider is set to a straight surface on the side near the slide block. A limiting plate is fixedly installed inside the baffle on the straight surface of the slider. The limiting plate limits the slider on one side, ensuring that the slider can move upward in a straight line under the push of the push plate to lift the abutment. A rotating plate is rotatably installed on the surface of the extension plate. A second torsion spring is provided between the rotating plate and the extension plate. The elastic force of the second torsion spring causes the rotating plate to return to its original position. A fixing plate is installed between the rotating plate and the extension plate. The fixing plate limits the rotating plate on one side, so that the rotating plate can only rotate in one direction.

[0011] According to the above technical solution, a second spring is provided between the slider and the abutment. The slider is connected to the abutment through the second spring, and the abutment is indirectly connected to the slider through the second spring, so that the slider can not only push the abutment to lift upward, but also push the abutment to deflect.

[0012] According to the above technical solution, suction cups are provided on both sides of the base, and a piston rod is slidably installed inside the suction cup. A lifting rod is fixedly installed on the surface of the cover. When the cover is opened, it drives the lifting rod to move and push the piston rod to lift, extracting the gas in the suction cup and creating a negative pressure between the suction cup and the outside to adhere to the work surface, ensuring that the base is stably placed on the work surface and avoiding shaking that would affect the core stripping effect. A rotating rod is rotatably installed on the piston rod near the lifting rod. A third torsion spring is provided between the rotating rod and the piston rod. The elastic force of the third torsion spring causes the rotating rod to return to its original position. A stop rod is fixedly installed on the surface of the piston rod near the rotating rod. The stop rod limits the rotating rod from above, so that the rotating rod can only rotate downwards in one direction and will not obstruct the return of the lifting rod. A support rod is rotatably installed on the surface of the piston rod. When the piston rod is lifted, it drives the support rod to rotate and press against the surface of the base, providing support for the piston rod and allowing the dryer to continuously extract gas from the inside of the suction cup.

[0013] According to the above technical solution, a flow valve is slidably installed on the surface of the base near the suction cup. A third spring is provided between the flow valve and the base. The flow valve is connected to the suction cup. A roller is rotatably installed on the support rod near the cover. A pressure rod is fixedly installed on the surface of the cover. When the cover is closed, the pressure rod is driven to squeeze the roller, causing the support rod to reset and rotate to release the support on the piston rod. After the piston rod resets, it releases the suction cup from the worktable, making it easier for the operator to pick up the equipment.

[0014] This invention provides an end-cap processing device for optical fibers. It has the following advantages:

[0015] (1) In this invention, the optical fiber is pushed against the baffle by the push bar to achieve alignment of all optical fibers, ensuring that the length of the exposed core part of the optical fiber is uniform after core stripping, and ensuring the fit between the end of the optical fiber and the connector. At the same time, after the push bar aligns the optical fiber, it will be lifted up, so that the inner wall of the sleeve slides along the surface of the optical fiber to straighten the surface of the optical fiber, avoiding the bending of the optical fiber during the core stripping process and affecting the core stripping effect.

[0016] (2) In this invention, by setting a stop plate inside the baffle, the stop plate automatically extends and abuts against the edge of the stripping area on the fiber surface during the stripping process, so that the melted coating layer collapses in the opposite direction of the stress of the stop plate, ensuring the flatness of the coating layer cut surface, which facilitates the subsequent fiber splicing. After the stripping is completed, the stop plate will also deflect to shape and quickly solidify the cut surface of the just melted coating layer, avoiding the coating layer after stripping from failing to solidify in time and collapsing randomly, which would affect the flatness of the fiber surface.

[0017] (3) When the equipment is not in use, the cover can be closed to protect the surface of the equipment and prevent dust and other debris from falling onto the surface of the equipment. When the equipment is in use, the cover can be opened to make the suction cup stick firmly to the workbench, ensuring the stability of the base and preventing the base from shaking during the operation and affecting the core stripping effect. When the equipment needs to be recycled and the cover is closed again, the suction cup will detach from the workbench, making it easy for the staff to pick up and carry the equipment.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1-10One embodiment of the present invention is as follows: an end-of-fiber processing device, comprising a base 1 and a cover 2, the cover 2 being rotatably mounted on the surface of the base 1, a heating seat 5 being mounted on the surface of the base 1, a pressure cover 6 being rotatably mounted on the surface of the heating seat 5, a sliding seat 3 being slidably mounted on the surface of the base 1, a clamping cover 4 being slidably mounted on the top of the sliding seat 3, a control console 7 being provided on the surface of the base 1, and a plurality of connecting rods 13 being rotatably mounted on the bottom of the clamping cover 4, a first torsion spring being provided between the connecting rods 13 and the clamping cover 4, and a push bar 8 being provided at the bottom of the connecting rods 13. When the clamping cover 4 moves downward, it will drive the push bar 8 to move. When the push bar 8 contacts the optical fiber, it is blocked by the optical fiber. When the clamping cover 4 continues to move, it will squeeze the connecting rods 13 to deflect. When the connecting rods 13 rotate, they push the push bar 8 to move. The push bar 8 drives the optical fiber to move towards the baffle 11. When the optical fiber contacts the surface of the baffle 11, it will stop moving. When all the optical fibers contact the baffle 11, the alignment of the optical fibers is completed. A first elastic telescopic rod 9 is slidably installed on the right side of the slide block 3. The baffle 11 is fixedly installed on the free end of the first elastic telescopic rod 9. The baffle 11 needs to be able to slide up and down and slide left and right at the same time. The baffle 11 and the slide block 3 are connected by the first elastic telescopic rod 9. At the same time, the elastic force of the first elastic telescopic rod 9 will cause the baffle 11 to return to its original position. A slide rod 10 is provided on the top of the baffle 11. A second elastic telescopic rod 20 is provided on the side of the heating seat 5 near the slide block 3. A first spring is provided between the slide rod 10 and the baffle 11. A pressure plate 12 is fixedly installed on the right side of the clamp cover 4. The clamp cover 4 moves downward to drive the pressure plate 12 to press down and push the baffle 11 downward.

[0031] A sleeve 14 is provided between the connecting rod 13 and the push bar 8. A guide rail 15 is provided on the surface of the sleeve 14. One end of the guide rail 15 is bent. The sleeve 14 is hinged to the bottom of the connecting rod 13. The push bar 8 is slidably installed in the guide rail 15. When all the optical fibers are aligned, the push bar 8 no longer pushes the optical fibers to move. The reaction force of the optical fibers on the push bar 8 causes the push bar 8 to move in the guide rail 15 and be lifted upward under the guidance of the bend of the guide rail 15, so that the sleeve 14 contacts the surface of the optical fibers. As the connecting rod 13 continues to push the sleeve 14 to move, an elastic element is provided between the push bar 8 and the guide rail 15. The elastic force of the elastic element causes the push bar 8 to return to its original position.

[0032] The connecting rod 13 is tilted and a second torsion spring is provided between it and the clamp 4. The connecting rod 13 is initially tilted and will deflect in the tilt direction when it is squeezed by the clamp 4. The elastic force of the second torsion spring will reset the connecting rod 13.

[0033] In this embodiment, before assembling the optical fiber, it is usually necessary to peel off the cladding layer at the very tip of the optical fiber to expose the inner core, which facilitates the assembly of the optical fiber with the connector. The installation of the optical fiber is completed by inserting the connector into the network equipment. However, in the prior art, the core is usually stripped by workers using hand-held stripping pliers or by heating, but it is difficult to align the optical fiber, resulting in uneven stripped lengths, which affects the connection effect between the optical fiber and the connector.

[0034] After opening cover 2, move cover 4 upwards to open it. Place the end of the fiber to be stripped flat on the surface of slide 3. Press cover 4 downwards. As cover 4 moves downwards, it drives push bar 8 to move towards the fiber surface. Because the initial position of connecting rod 13 is inclined, push bar 8 is blocked by the fiber surface after contacting the fiber. With the continued downward pressure of cover 4 and the blockage of the fiber, connecting rod 13 rotates and deflects. During the deflection process, it pushes the fiber towards the baffle 11. The fiber stops moving when it touches the surface of baffle 11. When all fibers have moved to contact baffle 11, the alignment between fibers is completed. The fiber is stripped in the aligned state to make the length of the exposed core uniform after stripping, which improves the fit with the connector and enhances the connection effect. After the optical fiber reaches the surface of the baffle 11, it will be fixed. At the same time, as the pusher 8 continues to apply force, the surface of the optical fiber generates a reaction force on the pusher 8, pushing the pusher 8 to move along the guide rail 15. When the pusher 8 passes the bend of the guide rail 15, it will enter the straight part of the guide rail 15 and be lifted. After being lifted, the pusher 8 releases the internal space of the sleeve 14, so that the inner wall edge of the sleeve 14 contacts the surface of the optical fiber. The connecting rod 13 continues to deflect, driving the sleeve 14 to move along the surface of the optical fiber. Through the guidance of the inner wall of the sleeve 14, the surface of the optical fiber is straightened, avoiding bending of the optical fiber during the core stripping process, which would affect the core stripping effect. After the clamp 4 completes the alignment of the optical fiber, it continues to move downward until it closes and fixes the optical fiber. At the same time, during the downward pressing of the clamp 4, the baffle 11 is pushed downward by the contact slide rod 10, so that the baffle 11 will not block the optical fiber from entering the heating seat 5. After the optical fiber is fixed, the slide 3 is pushed towards the heating seat 5 to move the optical fiber, so that the part of the optical fiber to be stripped enters the heating seat 5. At the same time, before the optical fiber enters the heating seat 5, the second elastic telescopic rod 20 will push the baffle 11 to the edge of the stripping area. The optical fiber in the stripping area smoothly enters the heating seat 5. The heating seat 5 heats and melts the coating layer on the surface of the optical fiber. With the pressure of the pressure cap 6, the melted coating layer is removed from the surface of the optical fiber, and the stripping is completed.

[0035] Please see Figures 1-10 Based on the above embodiments, in another embodiment of the present invention, a backing plate 16 is sleeved inside the baffle 11, a slider 18 is provided at the bottom of the backing plate 16, a slope is provided on the side of the slider 18 near the heating seat 5, an extension plate 19 is fixedly installed on the side of the heating seat 5 near the slide seat 3, and a push plate 21 is fixedly installed on the surface of the extension plate 19. The push plate 21 presses the slope at the bottom of the slider 18 to make the slider 18 move upward and lift the backing plate 16. After the slider 18 moves upward, it lifts the backing plate 16 from inside the baffle 11, so that the top of the backing plate 16 is pressed against the edge of the fiber stripping area.

[0036] The slider 18 is set to a straight surface on the side near the slide block 3. A limiting plate 17 is fixedly installed inside the baffle 11 on the straight surface of the slider 18. The limiting plate 17 limits the slider 18 on one side, ensuring that the slider 18 can move upward in a straight line under the push of the push plate 21 to lift the abutment plate 16. A rotating plate 22 is rotatably installed on the surface of the extension plate 19. A second torsion spring is provided between the rotating plate 22 and the extension plate 19. The elastic force of the second torsion spring causes the rotating plate 22 to return to its original position. A fixing plate 23 is installed between the rotating plate 22 and the extension plate 19. The fixing plate 23 limits the rotating plate 22 on one side, so that the rotating plate 22 can only rotate in one direction.

[0037] A second spring is provided between the slider 18 and the abutment 16. The slider 18 is connected to the abutment 16 through the second spring, and the abutment 16 is indirectly connected to the slider 18 through the second spring.

[0038] In this embodiment, during operation: While the second elastic telescopic rod 20 pushes the baffle 11, the extension plate 19 also gradually approaches the baffle 11. When the second elastic telescopic rod 20 pushes the baffle 11 to its maximum extent, the baffle 11 stops moving. At this point, the extension plate 19 has reached below the baffle 11 and drives the push plate 21 to press the bottom slope of the slider 18, pushing the slider 18 upward. After the slider 18 moves upward, it lifts the abutment plate 16 from inside the baffle 11, causing the top of the abutment plate 16 to press against the edge of the fiber stripping area. At the instant the coating on the surface of the stripping area melts, the abutment plate 16, driven by its upward movement, applies upward force. The melting coating layer is guided to collapse in the opposite direction of the stress on the abutment plate 16, ensuring the flatness of the coating layer's cross-section and facilitating subsequent fiber splicing. When the core stripping is completed and the slide block 3 is removed, the extension plate 19 moves away from the baffle plate 11, and at the same time, the rotating plate 22 pushes the flat surface of the slider 18 to move the slider 18. When the slider 18 moves, it drags the second spring, causing the second spring to pull the abutment plate 16 to deflect. The top of the deflected second spring will press against the coating layer's cross-section, shaping and quickly solidifying the newly melted coating layer's cross-section, preventing the melted coating layer from failing to solidify in time after core stripping and collapsing randomly, thus affecting the flatness of the fiber surface.

[0039] Please see Figures 1-10In another embodiment of the present invention, based on the above embodiments, suction cups 24 are provided on both sides of the base 1, and a piston rod 25 is slidably installed inside the suction cups 24. A lifting rod 26 is fixedly installed on the surface of the cover 2. When the cover 2 is opened, it drives the lifting rod 26 to move and push the piston rod 25 to lift, extracting the gas in the suction cups 24 so that the suction cups 24 and the outside form a negative pressure to adhere to the work surface. A rotating rod 28 is rotatably installed on the side of the piston rod 25 near the lifting rod 26. A third torsion spring is provided between the rotating rod 28 and the piston rod 25. The elastic force of the third torsion spring causes the rotating rod 28 to return to its original position. A stop rod 27 is fixedly installed on the surface of the piston rod 25 near the rotating rod 28. The stop rod 27 limits the rotating rod 28 from above, so that the rotating rod 28 can only rotate downward in one direction and will not block the return of the lifting rod 26. A support rod 30 is rotatably installed on the surface of the piston rod 25. When the piston rod 25 is lifted, it drives the support rod 30 to rotate and press against the surface of the base 1.

[0040] A flow valve 29 is slidably installed on the surface of the base 1 near the suction cup 24. A third spring is provided between the flow valve 29 and the base 1. The flow valve 29 is connected to the suction cup 24. A roller 32 is rotatably installed on the support rod 30 near the cover 2. A pressure rod 31 is fixedly installed on the surface of the cover 2. When the cover 2 is closed, the pressure rod 31 drives the roller 32 to squeeze, so that the support rod 30 returns to its original position and rotates to release the support of the piston rod 25.

[0041] In this embodiment, when the equipment is not in use, closing the cover 2 can shield the surface of the base 1, preventing dust from adhering. Each time the equipment is used, opening the cover 2 causes the lifting rod 26 to rotate. As the lifting rod 26 rotates, it presses against the rotating rod 28, causing the piston rod 25 to move upwards. When the piston rod 25 moves upwards, it draws in the gas inside the suction cup 24, causing the suction cup 24 to adhere to the worktable, thus stabilizing the base 1 and preventing it from shaking during operation, which could affect the core stripping effect. When the piston rod 25 is lifted upwards, it also lifts the support rod 3. Lift the support rod 30 so that its bottom is pressed against the surface of the base 1, supporting the piston rod 25 and keeping it in a stable position. The suction cup 24 is under negative pressure from the outside to prevent it from falling off. After the equipment is used, close the cover 2. The cover 2 drives the pressure rod 31 to squeeze the roller 32 to roll and push the support rod 30 to move away, releasing the support for the piston rod 25. The piston rod 25 returns to its original position. At the same time, the lifting rod 26 returns to its original position and squeezes the flow valve 29 to move downward, allowing the suction cup 24 to connect with the outside and release pressure. The suction cup 24 is removed from the workbench, making it easier for the staff to pick up and carry the equipment.
