Description

Technical Field

[0001] This invention relates to the field of optical fiber testing equipment technology, and more particularly to a cable routing device and an optical fiber sorting machine. Background Technology

[0002] Strength screening is an essential step in the optical fiber production process. An optical fiber screening machine is used to test and screen optical fibers. On the take-up side of the machine, a winding wheel guides the optical fiber to be neatly wound onto a take-up reel.

[0003] Currently, some fiber optic screening machines have rigidly fixed winding wheels on the take-up side, which lack the ability to adjust dynamically. This makes it difficult to effectively absorb tension fluctuations generated during fiber transmission, leading to wheel shaking and unstable fiber tension when fiber winding is poor. Consequently, the fiber may detach from the groove of the winding wheel, and "fiber throwing" or "fiber clamping" may occur during fiber winding, resulting in poor winding, affecting production efficiency and fiber quality.

[0004] Therefore, there is an urgent need for a cable routing device and an optical fiber sorting machine to solve the above problems. Summary of the Invention

[0005] One object of the present invention is to provide a fiber winding device that improves the quality and neatness of fiber winding, reduces rework and rewinding, and improves the production efficiency of fiber screening machines.

[0006] To achieve this objective, the present invention adopts the following technical solution: Cable routing device, including: The mounting frame has two guide rods spaced apart and parallel to each other. One end of each guide rod is connected to the mounting frame, and the other end is provided with a limiting component. The cable tray comprises a sliding seat, a connecting shaft, and a cable guide wheel. The two ends of the connecting shaft are respectively provided with the sliding seats, and the two sliding seats are respectively slidably engaged with the two guide rods. The cable guide wheel is rotatably mounted on the connecting shaft. The buffer assembly includes a first buffer and a second buffer. The first buffer is disposed between the sliding seat and the mounting bracket, and the second buffer is disposed between the sliding seat and the limiting member. Along the axial direction of the guide rod, the first buffer and the second buffer act on both ends of the sliding seat to provide bidirectional elastic support for the sliding seat.

[0007] Optionally, the first buffer and the second buffer are respectively a first compression spring and a second compression spring. The first compression spring and the second compression spring are both sleeved on the guide rod. One end of the first compression spring abuts against the mounting bracket and the other end abuts against the first end of the sliding seat. One end of the second compression spring abuts against the limiting member and the other end abuts against the second end of the sliding seat.

[0008] Optionally, the cable routing device further includes a fixing plate, which is fixed to the end of the guide rod away from the mounting bracket; The first buffer and the second buffer are respectively a first buffer and a second buffer. The first buffer is disposed on the mounting bracket, and the piston rod of the first buffer abuts against the first end of the sliding seat. The second buffer is disposed on the fixed plate, and the piston rod of the second buffer abuts against the second end of the sliding seat.

[0009] Optionally, both the first buffer and the second buffer are pneumatic buffers; Alternatively, both the first and second buffers may be hydraulic buffers.

[0010] Optionally, of the first buffer and the second buffer, one is a third compression spring and the other is a shock absorber. Along the axial direction of the guide rod, the piston rods of the third compression spring and the shock absorber elastically support the two ends of the sliding seat, respectively.

[0011] Optionally, the sliding seat is provided with a linear bearing, and the sliding seat is slidably connected to the guide rod through the linear bearing.

[0012] Optionally, the cable guide wheel has a groove in its circumference, and the sidewall of the groove gradually slopes outward from the bottom of the groove to the opening of the groove.

[0013] Optionally, the center of the cable guide wheel is provided with a mounting hole, and a first bearing is provided in the mounting hole. The inner ring of the first bearing is fixed to the connecting shaft, and the outer ring of the first bearing is fixed to the inner wall of the mounting hole.

[0014] Optionally, the cable routing device further includes a first fastener and a second fastener, the two guide rods are respectively a first guide rod and a second guide rod, the mounting bracket is provided with a first hole and a second hole, the first fastener passes through the first hole and is threadedly connected to the first guide rod, and the second fastener passes through the second hole and is threadedly connected to the second guide rod.

[0015] Another objective of this invention is to provide an optical fiber screening machine that improves the quality of optical fiber winding and the neatness of the wiring, reduces rework and rewinding, and improves the production efficiency of the optical fiber screening machine.

[0016] To achieve this objective, the present invention adopts the following technical solution: The optical fiber sorting machine includes a wire feeding device, a wire take-up device, and the aforementioned wire laying device. The optical fiber is led out by the wire feeding device, passes through the wire laying device, and is wound up by the wire take-up device.

[0017] Beneficial effects: The cable laying device provided by this invention has a first buffer and a second buffer respectively set at both ends of the sliding seat, so that the sliding seat is subjected to bidirectional elastic support in the axial direction of the guide rod. During the optical fiber transmission process, the optical fiber is wound around the cable laying wheel. When the tension of the optical fiber fluctuates, the sliding seat can generate displacement on the guide rod, and the tension fluctuation of the optical fiber is absorbed and buffered by the first buffer and the second buffer, preventing the optical fiber from falling off the cable laying wheel, thereby improving the optical fiber winding quality and cable laying neatness, reducing rework and rewinding work, and improving the production efficiency of the optical fiber screening machine.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0022] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0024] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0025] Example 1 This embodiment provides a cable routing device, such as... Figure 1As shown, the cable routing device includes a mounting frame 100, two guide rods 210, two sliding seats 220, a connecting shaft 310, a cable routing wheel 320, and a buffer assembly. The mounting frame 100 has two guide rods 210 spaced apart and parallel to each other. One end of each guide rod 210 is connected to the mounting frame 100, and the other end has a limiting member 211. The connecting shaft 310 has sliding seats 220 at both ends, and the two sliding seats 220 are slidably engaged with the two guide rods 210. The cable routing wheel 320 is rotatably mounted on the connecting shaft 310. The buffer assembly includes a first buffer member 410 and a second buffer member 420. The first buffer member 410 is disposed between the sliding seat 220 and the mounting frame 100, and the second buffer member 420 is disposed between the sliding seat 220 and the limiting member 211. Along the axial direction of the guide rods 210, the first buffer member 410 and the second buffer member 420 act on both ends of the sliding seat 220 to provide bidirectional elastic support for the sliding seat 220. During the transmission of optical fiber 10, optical fiber 10 is wound around the winding wheel 320. When the tension of optical fiber 10 fluctuates, the sliding seat 220 can generate displacement on the guide rod 210, and the tension fluctuation of optical fiber 10 is buffered by the first buffer 410 and the second buffer 420, preventing optical fiber 10 from falling off the winding wheel 320. This improves the winding quality and neatness of optical fiber 10, reduces rework and rewinding work, significantly reduces the incidence of "fiber throwing and fiber clamping" phenomena, and improves the production efficiency of the optical fiber screening machine and the quality of optical fiber 10.

[0026] Optionally, the limiting member 211 is a limiting screw, which includes a screw section and a head. The screw section is threadedly connected to the guide rod 210, and the end of the second elastic member away from the sliding seat 220 abuts against the head. In other embodiments, a washer can be provided at the limiting member 211, and the second compression spring abuts against the flat washer, thereby increasing the contact area with the second compression spring and preventing the second compression spring from dislodging from the guide rod 210.

[0027] In this embodiment, the bidirectional elastic support provided by the first buffer 410 and the second buffer 420 to the sliding seat 220 refers to two opposite directions along the axial direction of the guide rod 210.

[0028] like Figure 1As shown, the first buffer 410 and the second buffer 420 are respectively a first compression spring and a second compression spring. Both the first and second compression springs are sleeved on the guide rod 210. One end of the first compression spring abuts against the mounting bracket 100, and the other end abuts against the first end of the sliding seat 220. One end of the second compression spring abuts against the limiting member 211, and the other end abuts against the second end of the sliding seat 220. When the tension of the optical fiber 10 fluctuates, the first and second compression springs can buffer and adjust the displacement of the sliding seat 220 through their own compression and rebound, thereby effectively absorbing tension impact and improving the stability of the cabling process. In addition, the first and second compression springs have simple structures, are easy to install and maintain, effectively save production costs, and improve the convenience of later maintenance.

[0029] Optionally, the sliding seat 220 is equipped with a linear bearing. The sliding seat 220 is slidably connected to the guide rod 210 through the linear bearing, which can reduce the friction between the sliding seat 220 and the guide rod 210, avoid the sliding seat 220 from getting stuck during sliding, and allow the sliding seat 220 to work in conjunction with the first compression spring and the second compression spring, thereby responding more sensitively and accurately to the tension fluctuations of the optical fiber 10 and improving the cabling effect.

[0030] like Figure 1 As shown, the cable tray 320 has a circumferential groove 321. Along the direction from the bottom to the opening of the groove 321, the sidewall of the groove 321 gradually slopes outward. The sloped sidewall helps to guide the optical fiber 10 when it deviates, allowing the optical fiber 10 to automatically return to the bottom of the groove, thereby reducing the risk of the optical fiber 10 detaching from the groove 321, avoiding fiber breakage, and improving the cable tray quality.

[0031] Optionally, the cable guide wheel 320 has a mounting hole at its center, and a first bearing is installed in the mounting hole. The inner ring of the first bearing is fixed to the connecting shaft 310, and the outer ring of the first bearing is fixed to the inner wall of the mounting hole. By setting the first bearing, the cable guide wheel 320 is rolled relative to the connecting shaft 310, which can effectively reduce the frictional resistance during rotation and improve the rotational flexibility and smoothness of the cable guide wheel 320. Furthermore, by setting the first bearing, the rotational resistance of the cable guide wheel 320 is reduced, allowing the optical fiber 10 to smoothly drive the cable guide wheel 320 to rotate during transmission, further improving the cable quality.

[0032] Optionally, the connecting shaft 310 has a shoulder in the middle. When the cable guide wheel 320 is assembled onto the connecting shaft 310, one side of the inner ring of the first bearing abuts against the shoulder, and the other side of the inner ring of the first bearing is limited and fixed by a locking member, thereby achieving a fixed connection between the inner ring of the first bearing and the connecting shaft 310. It should be noted that the fixed connection method between the inner ring of the first bearing and the connecting shaft 310 is not limited to the above structure, and other fixing methods in the prior art can also be used, which will not be elaborated here.

[0033] Optionally, the cable routing device further includes a first fastener and a second fastener. The two guide rods 210 are respectively the first guide rod 210 and the second guide rod 210. The mounting bracket 100 has a first hole and a second hole. The first fastener passes through the first hole and is threadedly connected to the first guide rod 210, and the second fastener passes through the second hole and is threadedly connected to the second guide rod 210. This ensures that the first guide rod 210 and the second guide rod 210 are stably connected to the mounting bracket 100, and facilitates disassembly and assembly, improving efficiency. In this embodiment, the first fastener and the second fastener are respectively a first fastening screw and a second fastening screw.

[0034] Optionally, the sliding seat 220 is provided with an assembly groove, and the end of the connecting shaft 310 is inserted into the assembly groove, which helps to improve assembly efficiency and ease of assembly. Furthermore, the assembly groove is a D-shaped groove, and the cross-section of the end of the connecting shaft 310 is a D-shaped cross-section that is adapted to it, thereby forming a circumferential limit between the connecting shaft 310 and the sliding seat 220, preventing relative rotation between the two and improving the stability of the connection.

[0035] In other embodiments, the assembly groove can also be a rectangular groove, and the cross-section of the end of the connecting shaft 310 is a rectangular cross-section that is adapted to it. This can also achieve circumferential positioning between the connecting shaft 310 and the sliding seat 220, while taking into account the convenience of assembly.

[0036] Optionally, the second hole is an oblong hole, which facilitates adjusting the distance between the two first guide rods 210 and the second guide rod 210, thereby facilitating the assembly of the connecting shaft 310 between the first guide rod 210 and the second guide rod 210.

[0037] Optionally, the mounting bracket 100 includes a first support arm 110 and a second support arm 120. Both the first guide rod 210 and the second guide rod 210 are fixed to the first support arm 110. The second support arm 120 can be fixed to the cable tray arm on the take-up side of the fiber optic screening machine, improving the stability of the cable tray device. Specifically, the mounting bracket 100 can be fixed to the cable tray arm on the take-up side of the fiber optic screening machine using a third fastener, improving the stability of the mounting bracket 100 and facilitating assembly and disassembly. The third fastener is a third fastening screw, which has a simple structure, strong fastening force, and can improve the stability of the connection between the mounting bracket 100 and the cable tray wall.

[0038] The working process of the cable routing device provided in this embodiment is roughly as follows: When the tension of the optical fiber 10 increases, the tension of the optical fiber 10 will push the winding wheel 320 and the sliding seat 220 to move to one side along the guide rod 210, compressing the compression spring on that side and absorbing the tension energy; when the tension decreases, the compression spring on that side will push the sliding seat 220 to reset, so that the winding wheel 320 always maintains appropriate constraint on the optical fiber 10, preventing the optical fiber 10 from derailing or jumping, ensuring the winding quality of the optical fiber 10, reducing rework and rewinding, and improving production efficiency.

[0039] It should be noted that by selecting the stiffness of the compression spring, screening processes with different tension ranges can be adapted, thereby improving the adaptability of the wiring device.

[0040] Example 2 This embodiment provides a cable laying device, which is basically the same as that in Embodiment 1, except that the cable laying device further includes a fixing plate, which is fixed to the end of the guide rod 210 away from the mounting frame 100. The first buffer 410 and the second buffer 420 are respectively the first buffer and the second buffer. The first buffer is disposed on the mounting frame 100, and the piston rod of the first buffer abuts against the first end of the sliding seat 220. The second buffer is disposed on the fixing plate, and the piston rod of the second buffer abuts against the second end of the sliding seat 220. With the above design, during the transmission of the optical fiber 10, the optical fiber 10 winds around the cable laying wheel 320. When the tension of the optical fiber 10 fluctuates, the sliding seat 220 can be displaced on the guide rod 210, and the tension fluctuation is buffered by the first buffer and the second buffer, preventing the optical fiber 10 from detaching from the cable laying wheel 320. This improves the winding quality and neatness of the optical fiber 10, reduces rework and rewinding work, and improves the production efficiency of the optical fiber screening machine.

[0041] Optionally, both the first and second buffers are pneumatic buffers, which have a faster response speed and a relatively simple structure. In other embodiments, both the first and second buffers are hydraulic buffers, which have better damping stability and can better reduce the jitter caused by tension fluctuations in the optical fiber 10, thereby improving the quality of the wound optical fiber 10.

[0042] Example 3 This embodiment provides a cable laying device, which is basically the same as that of Embodiment 1, except that: of the first buffer 410 and the second buffer 420, one is a third compression spring and the other is a vibration damper. Along the axial direction of the guide rod 210, the piston rods of the third compression spring and the vibration damper elastically support the two ends of the sliding seat 220, respectively. During the transmission of the optical fiber 10, the optical fiber 10 winds around the cable laying wheel 320. When the tension of the optical fiber 10 fluctuates, the sliding seat 220 can generate displacement on the guide rod 210, and absorb and buffer the tension fluctuation of the optical fiber 10 through the third compression spring and the vibration damper, preventing the optical fiber 10 from detaching from the cable laying wheel 320. This improves the winding quality and neatness of the optical fiber 10, reduces rework and rewinding work, and improves the production efficiency of the optical fiber screening machine and the quality of the optical fiber 10.

[0043] It should be noted that the structure of the vibration damper in this embodiment is existing technology, and the specific structure of the vibration damper will not be described in detail.

[0044] Example 4 This embodiment provides an optical fiber sorting machine, including a wire feeding device, a wire take-up device, and a wire winding device as described in any of the above embodiments. The optical fiber 10 is led out by the wire feeding device, wound around the wire winding device, and then wound up by the wire take-up device. By applying the above-mentioned wire winding device, rework and rewinding are reduced, improving the production efficiency of the optical fiber sorting machine and the winding quality of the optical fiber 10. At the same time, the wire winding device has a simple structure and is easy to install, which helps to improve the convenience of maintenance of the optical fiber sorting machine.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
