Description

Technical Field

[0001] This utility model relates to the field of communication optical cable technology, and in particular to an adjustable servo cable laying device. Background Technology

[0002] With the rapid development of 5G base stations, industrial internet, smart cities, and other fields, the demand for communication optical cables has increased significantly. Increased internet penetration places higher demands on network transmission efficiency and coverage. This greater demand makes the automation and unmanned operation of optical cable manufacturing imperative. Optical cable laying is typically the final process in this process.

[0003] Currently, traditional cable laying systems are mostly manual or manually assisted, requiring personnel to continuously operate or make adjustments at this workstation.

[0004] Traditional cable laying systems have the following problems: 1. High degree of manual intervention: Traditional cable laying relies on manual experience for adjustment, which is inefficient and prone to errors; Second, the labor intensity of personnel is high: Traditional cable laying cannot be separated from manual labor, and the continuous nature of cable production means that cable laying personnel cannot leave their posts at all times, resulting in a high labor intensity. Third, due to the uncontrollable state of personnel, high-intensity work can lead to fatigue and negligence, making it easy for personnel to be caught in the wire reeling equipment, resulting in injury or death, posing a high risk.

[0005] IV. Insufficient real-time monitoring: The inability to monitor the status of optical cables in real time leads to delays in troubleshooting. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model discloses an adjustable servo cable management device.

[0007] The technical solution adopted in this utility model is as follows: An adjustable servo cable management device includes: Base plate; A set of concentric clamping wheels is fixedly mounted on one side of the base plate; A fixed plate is movably disposed on the other side of the base plate; A set of eccentric clamping wheels is installed on the fixed plate; a channel for optical cable to pass through is formed between the concentric clamping wheels and the eccentric clamping wheels; The adjustment module includes adjustment bolts that are elastically connected to the fixed plate; Specifically, by rotating the adjusting bolt, the fixed plate is displaced, thereby changing the distance between the eccentric clamping wheel and the concentric clamping wheel.

[0008] In one embodiment of this utility model, the adjustment module further includes a mounting plate, an adjustment plate, a fixed shaft, and an elastic element; the mounting plate is fixed to the base plate; the adjustment bolt passes axially through the mounting plate, and the end of the adjustment bolt faces the adjustment plate; one end of the fixed shaft is fixed to the adjustment plate, and the other end is fixed to the fixed plate; the elastic element is sleeved on the fixed shaft, and one end of the elastic element abuts against the adjustment plate, and the other end abuts against the mounting plate.

[0010] In one embodiment of this utility model, the drive source includes a servo motor and a reducer connected to the output end of the servo motor; the output end of the reducer is connected to the concentric clamping wheel.

[0011] In one embodiment of this utility model, an encoder connected to the concentric clamping wheel is also included.

[0012] In one embodiment of the present invention, at least one set of guide modules is further included; the guide modules are configured to guide the fixed plate to slide in the horizontal direction.

Independent adjustable eccentric clamping rollers ensure that each set of eccentric and concentric clamping rollers provides the same clamping force to the optical cable. Furthermore, any dimensional errors in the outer diameter of the rubber-coated rollers or wear on the rubber-coated parts of the clamping rollers after long-term use can be addressed by adjusting the eccentricity of the eccentric clamping rollers, ensuring the stability of the adjustable servo cable laying device and significantly increasing its service life, eliminating the need for frequent roller replacements.

[0018] The adjustable servo cable laying device described in this utility model adopts a servo-driven traction structure, which can apply a constant traction force to the optical cable. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0025] The foregoing and other technical contents, features, and effects of this utility model will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present utility model. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0026] In the current technology, the optical cable manufacturing industry has long relied on manual cable laying operations. Traditional cable laying systems require continuous human intervention to adjust the clamping roller spacing, resulting in limited production efficiency and safety hazards. With the surge in demand for communication optical cables, automated cable laying equipment has become an urgent need in the industry. However, existing technologies cannot achieve rapid adaptive adjustment of the clamping roller spacing, making it difficult to meet the continuous production needs of optical cables of different specifications.

[0027] To address the aforementioned issues, the inventors discovered that the fixed structure of traditional clamping wheel devices cannot adapt to changes in optical cable diameter, necessitating the design of a dynamically adjustable clamping mechanism. By analyzing the clamping wheel's motion trajectory, they proposed using an eccentric wheel structure to achieve asymmetrical clamping, combined with an elastic adjustment mechanism to maintain a constant clamping force. Further investigation revealed that simply moving the clamping wheel would cause instability in the transmission system; therefore, the driving end was designed as a fixed concentric wheel, while the driven end employed an adjustable eccentric wheel, forming a stable clamping channel.

[0028] Therefore, combining Figures 1 to 3 This embodiment proposes a device including a base plate 1, a concentric clamping wheel assembly on the fixed side, an eccentric clamping wheel assembly on the movable side, and an adjustment module 8. The base plate 1 serves as the load-bearing foundation. Concentric clamping wheels 6 are installed on the fixed side, and eccentric clamping wheels 7 are installed on the movable side via a fixed plate 4. An optical cable 9 channel is formed between the concentric clamping wheels 6 and the eccentric clamping wheels 7. The adjustment module 8 includes an adjustment bolt 82 elastically connected to the fixed plate 4. By turning the adjustment bolt 82, the fixed plate 4 is displaced, changing the distance between the eccentric clamping wheels 7 and the concentric clamping wheels 6.

[0029] Among them, the base plate 1 refers to the foundation platform supporting the entire device, which can be made of steel plate with mounting and positioning holes on its surface for fixing various components. The concentric clamping wheel 6 refers to a clamping wheel with a fixed axis, which can be a steel core wheel with keyways installed in conjunction with a bearing seat, and the wheel surface covered with polyurethane material to increase friction. The eccentric clamping wheel 7 refers to a clamping wheel whose mounting axis is offset from the geometric center, which can be an eccentric bushing structure, and the clamping point position can be changed by adjusting the installation angle. The adjusting module 8 refers to the mechanical device that controls the spacing between the clamping wheels.

[0030] This embodiment further proposes that the adjustment module 8 also includes a mounting plate clamping wheel 84, an adjusting plate clamping wheel 83, a fixed shaft, and an elastic element clamping wheel 81. The mounting plate clamping wheel 84 is fixed to the base plate clamping wheel 1. The adjusting bolt clamping wheel 82 passes axially through the mounting plate clamping wheel 84, and the end of the adjusting bolt clamping wheel 82 faces the adjusting plate clamping wheel 83. One end of the fixed shaft is fixed to the adjusting plate clamping wheel 83, and the other end is fixed to the fixed plate clamping wheel 4. The elastic element clamping wheel 81 is sleeved on the fixed shaft, and one end of the elastic element clamping wheel 81 abuts against the adjusting plate clamping wheel 83, and the other end abuts against the mounting plate clamping wheel 84.

[0031] The mounting plate 84 is a rigid structural component fixed on the base plate 1 to support the adjusting bolt 82. Specifically, it can be a steel plate fixed on the base plate 1 by bolt connection to provide axial movement constraints for the adjusting bolt 82.

[0032] Adjusting plate 83 refers to the force-bearing component that contacts the end of adjusting bolt 82, and is used to convert the axial displacement of adjusting bolt 82 into linear motion of fixed shaft.

[0033] The fixed shaft refers to the transmission component that connects the adjusting plate 83 and the fixed plate 4. Specifically, it can be a chrome-plated steel rod with threads connecting both ends, used to synchronously transmit the displacement of the adjusting plate 83 to the fixed plate 4.

[0034] The elastic element 81 refers to the energy storage component that provides the restoring force. Specifically, it can be a helical spring sleeved around the fixed shaft to maintain a constant pressure between the eccentric clamping wheel 7 and the optical cable 9 during the adjustment process.

[0035] Specifically, when the adjusting bolt 82 is rotated, its end pushes the adjusting plate 83 to move along the axis of the fixed shaft, causing the fixed plate 4 to move synchronously, thereby changing the distance between the eccentric clamping wheel 7 and the concentric clamping wheel 6. The elastic element 81 is compressed or released during the adjustment process, always maintaining elastic contact between the adjusting plate 83 and the mounting plate 84. After adjustment, the preload of the elastic element 81 can counteract gap changes caused by equipment vibration or deformation of the optical cable 9, ensuring that the distance between the eccentric clamping wheel 7 and the concentric clamping wheel 6 remains stable.

[0036] This embodiment further proposes a drive source clamping wheel 2 connected to the concentric clamping wheel 6. Specifically, the drive source 2 includes a servo motor and a reducer connected to the output end of the servo motor. The output end of the reducer is connected to the concentric clamping wheel 6.

[0037] The servo motor refers to a drive device whose speed and torque are controlled by electrical signals. It can adjust its output power in real time according to the transmission requirements of the optical cable 9. The reducer is a transmission mechanism that converts the high-speed, low-torque output of the servo motor into low-speed, high-torque output. Specifically, it can be implemented using a planetary gear reducer or a worm gear reducer. By reducing the speed and amplifying the torque, it ensures that the concentric clamping wheel 6 maintains stable rotation when pulling the optical cable 9.

[0038] Specifically, the output shaft of the servo motor is rigidly connected to the input end of the reducer via a coupling, and the output end of the reducer is fixed to the central shaft of the concentric clamping wheel 6 via a keyway. When the servo motor receives a control signal, its output speed is precisely adjusted, and the power is transmitted to the concentric clamping wheel 6 via the reducer, causing the concentric clamping wheel 6 to rotate at a set speed. The optical cable 9 is clamped in the channel formed by the concentric clamping wheel 6 and the eccentric clamping wheel 7, and is pulled and conveyed as the clamping wheels rotate.

[0039] This embodiment further proposes an encoder 3 that is connected to the concentric clamping wheel 6.

[0040] The encoder 3 refers to the detection device that converts the rotational motion of the concentric clamping wheel 6 into an electrical signal. Specifically, it can be implemented using a rotary encoder, such as a photoelectric encoder or a magnetic encoder. By monitoring the rotational speed and amount of rotation of the concentric clamping wheel 6 in real time, the transmission length of the optical cable 9 can be directly reflected, thereby replacing manual experience judgment and solving the technical problem that traditional cable laying systems cannot monitor the status of the optical cable 9 in real time.

[0041] Specifically, encoder 3 rotates synchronously with concentric clamping wheel 6 via a coupling or drive shaft, and its output is connected to the control system. When concentric clamping wheel 6 drives optical cable 9 to move, encoder 3 converts the rotation angle into a pulse signal, which is then processed to generate length data for optical cable 9. This data can be transmitted to the control terminal in real time to achieve automatic calibration of metering accuracy, and at the same time provide feedback for the synchronous control of cable laying speed and take-up equipment.

[0042] It should be noted that in this embodiment, each group of concentric clamping wheels 6 has three clamping wheels, and each group of eccentric clamping wheels 7 has three clamping wheels. For ease of description, the three concentric clamping wheels 6 are defined as the first concentric clamping wheel, the second concentric clamping wheel, and the third concentric clamping wheel, and the three eccentric clamping wheels 7 are defined as the first eccentric clamping wheel, the second eccentric clamping wheel, and the third eccentric clamping wheel. The first concentric clamping wheel is connected to the drive source 2, and the second concentric clamping wheel is connected to the encoder 3.

[0043] This embodiment further proposes that the adjustable servo cable management device also includes at least one set of guide module clamping wheels 5. The guide module clamping wheels 5 are configured to guide the fixed plate clamping wheels 4 to slide in the horizontal direction. Specifically, the guide module clamping wheels 5 include a guide rail arranged in the horizontal direction and a slider that slides along the guide rail. The slider and the fixed plate clamping wheels 4 are fixedly connected.

[0044] The guide rail refers to a linear track structure extending horizontally, which can be implemented using a straight metal track or a ball bearing guide rail. The slider is a sliding component that cooperates with the guide rail, which can be implemented using a sliding seat with balls or rollers, with lubricating material embedded inside to reduce frictional resistance. The cooperation between the guide rail and the slider provides a stable sliding path for the fixed plate 4, ensuring that the fixed plate 4 moves in the predetermined direction during adjustment and avoiding deviation or jamming.

[0045] Specifically, when the adjusting module 8 pushes or pulls the fixing plate 4 via the adjusting bolt 82, the slider moves horizontally along the sliding trajectory of the guide rail, precisely adjusting the distance between the eccentric clamping wheel 7 and the concentric clamping wheel 6. The linear constraint of the guide rail restricts the degree of freedom of the fixing plate 4 in the non-horizontal direction, ensuring that the eccentric clamping wheel 7 always remains parallel and aligned with the concentric clamping wheel 6, thereby maintaining a uniform clamping force in the optical cable 9 channel. For example, the guide rail can be fixed to the base plate 1 with bolts, and the bottom of the slider in contact with the guide rail is coated with polytetrafluoroethylene to reduce sliding resistance.

[0046] This embodiment further proposes that the number of concentric clamping wheels 6 and the number of eccentric clamping wheels 7 are the same. The positions of each concentric clamping wheel 6 and each eccentric clamping wheel 7 correspond.

[0047] The same quantity means that the number of concentric clamping wheels 6 and eccentric clamping wheels 7 are in a one-to-one correspondence in terms of their arrangement. Specifically, a symmetrical layout can be adopted to ensure that the clamping force of each contact point of the optical cable 9 is evenly distributed during transmission.

[0048] Positional correspondence means that each concentric clamping wheel and its corresponding eccentric clamping wheel are in the same vertical plane in the axial direction. Its function is to prevent the optical cable 9 from shifting laterally during the clamping process. It can be understood that the first concentric clamping wheel and the first eccentric clamping wheel, the second concentric clamping wheel and the second eccentric clamping wheel, and the third concentric clamping wheel and the third eccentric clamping wheel are symmetrically distributed about the axis of symmetry of the base plate 1.

[0049] Specifically, when the optical cable 9 enters the clamping channel formed by the concentric clamping rollers 6 and the eccentric clamping rollers 7, the paired clamping rollers apply clamping force synchronously at axially symmetrical positions. Through the matched set of clamping rollers, each contact point on the surface of the optical cable 9 receives balanced radial pressure, effectively eliminating localized stress concentration. The corresponding layout ensures that the optical cable 9 remains within the central axis region of the clamping roller set during transmission, preventing serpentine swaying caused by misalignment of the clamping rollers.

[0050] This embodiment further proposes that the concentric clamping wheel 6 and the eccentric clamping wheel 7 have the same diameter.

[0051] Among them, "same diameter" means that the maximum outer circumferential dimensions of the concentric clamping wheel 6 and the eccentric clamping wheel 7 are the same.

[0052] Specifically, when the optical cable 9 passes through the channel formed by the concentric clamping wheel 6 and the eccentric clamping wheel 7, the identical diameter of both creates a symmetrical contact surface during clamping. This symmetrical structure ensures a uniform radial pressure distribution on the optical cable 9 during traction, preventing localized stress concentration caused by diameter differences. When the adjusting module 8 drives the eccentric clamping wheel 7 closer to the concentric clamping wheel 6, the identical diameter design ensures that the adjustment of the clamping gap depends solely on the displacement of the eccentric clamping wheel 7, eliminating the need for additional compensation for clamping force deviations caused by diameter differences.

[0053] In some specific embodiments, the surfaces of the concentric clamping wheel 6 and the eccentric clamping wheel 7 may be provided with anti-slip textures, such as diamond grids or wavy groove structures, to enhance the friction against the surface of the optical cable 9.

[0054] This embodiment further proposes that the concentric clamping wheel 6 and the eccentric clamping wheel 7 are polyurethane-coated wheels.

[0055] Among them, polyurethane-coated wheels refer to composite structure wheels with a metal wheel body as the base and a polyurethane elastic layer wrapped on the surface. This material has high wear resistance, resistance to compression deformation and elastic recovery ability, and can form a buffer contact surface when clamping optical cable 9, avoiding surface damage caused by rigid friction.

[0056] Specifically, when the optical cable 9 passes through the channel formed by the concentric clamping rollers 6 and eccentric clamping rollers 7, the polyurethane coating layer generates a uniform clamping force through elastic deformation. Its surface friction coefficient can be controlled within the range of 0.6-0.8, providing sufficient traction to prevent slippage without causing deformation of the optical cable 9 sheath due to pressure concentration. During continuous operation, the unique tear resistance of the polyurethane material can withstand repeated friction from the metal reinforcements on the surface of the optical cable 9, while its oil resistance prevents lubricants in the production environment from penetrating and causing material expansion and failure.

[0057] The working principle of this utility model is as follows: When the clamping channel width needs to be adjusted, the operator rotates the adjusting bolt 82 to move the adjusting plate 83. The fixed shaft drives the fixed plate 4 to slide horizontally along the guide rail. At this time, the elastic element 81 is compressed, generating a reverse force. The eccentric clamping wheel 7 changes its relative position with the concentric clamping wheel 6 as the fixed plate 4 moves. Due to the eccentric structure, the clamping contact point produces a non-linear displacement change, which can achieve a large clamping range adjustment within a small adjustment stroke. When the optical cable 9 passes through the channel formed by the two sets of clamping wheels, namely the concentric clamping wheel 6 and the eccentric clamping wheel 7, the rotational motion of the eccentric clamping wheel 7 generates a uniform linear velocity, which, together with the active drive of the concentric clamping wheel 6, achieves stable cable laying.

[0058] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
