There are two main methods for adjusting the pins: automatic and manual. Products with automatic pin adjustment are expensive, have high maintenance costs, are complex to operate, and have low cutting efficiency. Manual pin adjustment suffers from poor compatibility with different fibers, requires frequent adjustments, demands a high level of expertise from the operator, and results in poor cutting stability and a low success rate. Utility Model Content

[0003] The main purpose of this invention is to provide a polarization-maintaining fiber cleaving device and equipment, which aims to improve the efficiency of polarization-maintaining fiber cleaving.

[0004] To achieve the above objectives, the present invention proposes a polarization-maintaining fiber cleaving device, comprising: Base; A pin module, comprising a pin and a drive unit, wherein the pin is disposed on one side of the polarization-maintaining fiber axis, and the drive unit is connected to the pin and can drive the pin to move closer to or away from the polarization-maintaining fiber. A tension measurement module is provided on the base and is used to detect the tension when the polarization-maintaining fiber is fixed. The driving component drives the pin to abut against the polarization-maintaining fiber to achieve the pin being in position.

[0005] In one embodiment, the tension measurement module includes a tension sensor and a controller. The tension sensor is connected to the pin to detect the tension of the polarization-maintaining fiber, and the tension sensor is electrically connected to the controller.

[0006] In one embodiment, the ejector module further includes an ejector mounting base and a guide rail assembly. The ejector is connected to the ejector mounting base. The guide rail assembly includes a first slide rail and a second slide rail extending along the ejector movement direction. The first slide rail is fixed to the base. The second slide rail is connected to the first slide rail and can slide relative to the first slide rail. The ejector mounting base is connected to the second slide rail. The output end of the drive unit is connected to the ejector mounting base.

[0007] In one embodiment, the ejector pin module further includes a tension spring assembly, which includes a tension spring, a first fixing member, and a second fixing member. The two ends of the tension spring in the extension direction are respectively connected to the first fixing member and the second fixing member. The first fixing member is connected to the ejector pin mounting seat, and the second fixing member is connected to the base.

[0008] In one embodiment, the polarization-maintaining fiber cleaving device further includes a cleaving module, which includes a cleaving blade and a blade holder. The blade holder is movably connected to the base, and the cleaving blade is connected to the blade holder and located on the opposite side of the pin module relative to the polarization-maintaining fiber.

[0009] In one embodiment, the cutting module further includes an adjustment seat rotatably connected to the base, and the blade holder is detachably connected to the adjustment seat to adjust the pitch angle of the blade holder.

[0010] In one embodiment, the cutting module further includes an angle sensor connected to the adjustment seat to detect the pitch angle of the adjustment seat relative to the base.

[0011] In one embodiment, the blade holder has an opening on the side facing the polarization-maintaining fiber, a snap-fit ​​groove is formed in the opening, the cleaver is snapped into the snap-fit ​​groove, and fixing holes are formed on opposite sides of the opening. The fixing holes are used to insert fasteners to adjust the size of the opening so as to fix the cleaver on the blade holder.

[0012] This utility model also proposes a polarization-maintaining fiber cleaving device, which includes the polarization-maintaining fiber cleaving apparatus described above, and A fixing device for fixing the polarization-maintaining optical fiber.

[0013] This utility model proposes a polarization-maintaining fiber cleaving device, belonging to the field of fiber optic processing equipment. It is suitable for precision cleaving of polarization-maintaining fibers in optical communication, fiber optic sensing, and other fields. Through the cooperation of a pin module and a tension measurement module, it ensures that the polarization-maintaining fiber is accurately cut under a preset tension, guaranteeing the flatness of the cut end and the fiber performance. The device mainly consists of a base, a pin module, and a tension measurement module. The base has high structural rigidity and stability, and its upper surface is ground to form a flat mounting reference surface for mounting components such as the pin module and the tension measurement module. A leveling bolt is provided at the bottom of the base, allowing the base to be kept level by adjusting the bolt height, preventing tilting from affecting cutting accuracy. The pins of the pin module have high hardness and wear resistance, allowing for precise contact with the side of the polarization-maintaining fiber. The driving component is a linear motor, fixed to the base by bolts. Its output shaft is coaxially connected to the pin, driving the pin to move linearly along the radial direction of the polarization-maintaining fiber, enabling the pin to move closer to or away from the fiber. The tension measurement module is installed on one side of the base and connected to the fixed end of the polarization-maintaining fiber. It can detect the tension value of the polarization-maintaining fiber in real time when it is fixed. During the cutting process, after the fixing device applies tension to the polarization-maintaining fiber to a predetermined value, it releases the motor that applied the tension, allowing the tension of the polarization-maintaining fiber to be maintained by friction. The tension measurement value of the polarization-maintaining fiber measured by the tension measurement module will only decrease slightly and will not increase. At this time, the drive component pushes the ejector pin closer to the polarization-maintaining fiber. When the ejector pin touches the polarization-maintaining fiber, the deformation of the fiber will cause the tension measured by the tension measurement module to increase. This indicates that the ejector pin has found the position of the polarization-maintaining fiber, and then the ejector pin moves to the designated position, thus achieving automatic positioning of the ejector pin. This improves the convenience of subsequent cutting. Attached Figure Description

[0021] Currently, the market standard for polarization-maintaining fiber, large-diameter fiber (500µm and above), and fiber optic bundle splitting techniques all utilize adjusting pins. There are two main methods for adjusting the pins: automatic and manual. Products with automatic pin adjustment are expensive, have high maintenance costs, are complex to operate, and have low cutting efficiency. Manual pin adjustment suffers from poor compatibility with different fibers, requires frequent adjustments, demands a high level of expertise from the operator, and results in poor cutting stability and a low success rate.

[0022] To solve the above problems, please refer to... Figures 1 to 4 This utility model proposes a polarization-maintaining fiber cutting device 100, including a base 1, a pin module 2, and a tension measuring module. The pin module 2 includes a pin 21 and a driving member 22. The pin 21 is located on one side of the axial direction of the polarization-maintaining fiber 200. The driving member 22 is connected to the pin 21 and can drive the pin 21 to move closer to or away from the polarization-maintaining fiber 200. The tension measuring module is located on the base 1 and is used to detect the tension when the polarization-maintaining fiber 200 is fixed. The driving member 22 drives the pin 21 to abut against the polarization-maintaining fiber 200 to realize the pin 21 in place.

[0023] This utility model proposes a polarization-maintaining fiber cleaving device 100, belonging to the field of fiber optic processing equipment. It is suitable for precision cleaving of polarization-maintaining fibers 200 in fields such as optical communication and fiber optic sensing. Through the cooperation of the ejector module 2 and the tension measurement module, it ensures that the polarization-maintaining fiber 200 is accurately cut under a preset tension, guaranteeing the flatness of the cut end face and the fiber performance. The device mainly consists of a base 1, an ejector module 2, and a tension measurement module. The base 1 has high structural rigidity and stability, and its upper surface is ground to form a flat mounting reference surface for mounting components such as the ejector module 2 and the tension measurement module. The bottom of the base 1 is equipped with leveling bolts, which can be adjusted to keep the base 1 level, avoiding the impact of tilting on cutting accuracy. The ejector pins 21 of the ejector module 2 have high hardness and wear resistance, allowing for precise contact with the side of the polarization-maintaining fiber 200. The drive unit 22 is a linear motor, fixed to the base 1 by bolts. Its output shaft is coaxially connected to the ejector pin 21, driving the ejector pin 21 to move linearly along the radial direction of the polarization-maintaining fiber 200, thus moving the ejector pin 21 closer to or further away from the polarization-maintaining fiber 200. A tension measurement module is installed on one side of the base 1 and connected to the fixed end of the polarization-maintaining fiber 200, allowing real-time detection of the tension value of the polarization-maintaining fiber 200 when it is fixed. During the cutting process, after the fixing device applies tension to the polarization-maintaining fiber 200 to a predetermined value, it releases the motor that applied the tension, allowing the tension of the polarization-maintaining fiber 200 to be maintained by friction. Therefore, the tension measurement value of the polarization-maintaining fiber 200 by the tension measurement module will only decrease slightly and will not increase. At this time, the drive unit 22 pushes the ejector pin 21 closer to the polarization-maintaining fiber 200. When the ejector pin 21 touches the polarization-maintaining fiber 200, the deformation of the fiber will cause the tension measured by the tension measurement module to increase. This indicates that the ejector pin 21 has found the position of the polarization-maintaining fiber 200, and then the ejector pin 21 moves to the designated position, thereby achieving automatic positioning of the ejector pin 21. This improves the convenience of subsequent cutting.

[0024] Furthermore, in one embodiment, the tension measurement module includes a tension sensor and a controller. The tension sensor is connected to the pin 21 to detect the tension of the polarization-maintaining fiber 200, and the tension sensor is electrically connected to the controller.

[0025] The tension measurement module includes a tension sensor and a controller. The controller can be an embedded microprocessor, electrically connected to the tension sensor and the drive unit 22 via wires. It has a preset target tension value for the positioning of the ejector pin 21. When the polarization-maintaining fiber 200 is fixed solely by friction between itself and the fixing device, the tension of the fiber gradually increases when the ejector pin 21 abuts against it. The tension sensor transmits the detected tension signal to the controller, which processes the signal and compares it with the preset value. When the actual tension reaches the target value, the controller sends a stop signal to the drive unit 22, causing the drive unit 22 to stop moving, and the ejector pin 21 maintains its current position, completing the positioning.

[0026] In one embodiment, the ejector module 2 further includes an ejector mounting base 23 and a guide rail assembly 24. The ejector 21 is connected to the ejector mounting base 23. The guide rail assembly 24 includes a first slide rail 241 and a second slide rail 242 extending along the moving direction of the ejector 21. The first slide rail 241 is fixed to the base 1. The second slide rail 242 is connected to the first slide rail 241 and can slide relative to the first slide rail 241. The ejector mounting base 23 is connected to the second slide rail 242. The output end of the drive unit 22 is connected to the ejector mounting base 23.

[0027] The ejector pin module 2 also includes an ejector pin mounting base 23 and a guide rail assembly 24. The ejector pin mounting base 23 is a block structure made of aluminum alloy. The ejector pin 21 is fixed to the front end of the mounting base by a threaded connection, ensuring that the axis of the ejector pin 21 is aligned with the radial direction of the polarization-maintaining fiber 200. The first slide rail 241 of the guide rail assembly 24 is a linear guide rail, which is fixed to the mounting reference surface of the base 1 by bolts and extends along the moving direction of the ejector pin 21. The second slide rail 242 is a slider that matches the first slide rail 241 and can slide along the length direction of the first slide rail 241 to ensure smooth movement. The ejector pin mounting base 23 is bolted to the upper surface of the second slide rail 242, and the output end of the drive unit 22 is connected to the rear end of the ejector pin mounting base 23 through a coupling. When the drive unit 22 is working, the output end pushes the ejector pin mounting base 23 to move along the mating direction of the first slide rail 241 and the second slide rail 242, causing the ejector pin 21 to move linearly. The guide rail assembly 24 provides precise guidance for the movement of the ejector pin 21, preventing the ejector pin 21 from deviating or tilting during movement, ensuring that the ejector pin 21 always applies pressure along the radial direction of the optical fiber, reducing the problem of uneven force on the optical fiber caused by the deviation of the ejector pin 21. At the same time, the low-gap slide rail ensures the movement accuracy of the ejector pin 21, further improving the accuracy of tension control and measurement.

[0028] In one embodiment, the ejector pin module 2 further includes a tension spring assembly 25, which includes a tension spring 251, a first fixing member 252 and a second fixing member 253. The two ends of the extension direction of the tension spring 251 are respectively connected to the first fixing member 252 and the second fixing member 253. The first fixing member 252 is connected to the ejector pin mounting seat 23, and the second fixing member 253 is connected to the base 1.

[0029] The ejector pin module 2 also includes a tension spring assembly 25. The tension spring 251 of the tension spring assembly 25 is a cylindrical helical spring made of stainless steel with a stable elastic coefficient. Its two ends in the extension direction are connected to the first fixing member 252 and the second fixing member 253 respectively through hooks. The first fixing member 252 and the second fixing member 253 are both metal pins. The first fixing member 252 is vertically fixed to the top of the ejector pin mounting base 23; the second fixing member 253 is fixed to the base 1 and aligned with the first fixing member 252 in the moving direction of the ejector pin 21. When the driving member 22 drives the ejector pin mounting base 23 to move closer to the polarization-maintaining fiber 200, the tension spring 251 is stretched and stores elastic potential energy. After the cutting is completed, the driving member 22 reverses its action, the tension spring 251 releases the elastic potential energy, assists the ejector pin mounting base 23 to reset, and makes the ejector pin 21 quickly move away from the optical fiber. The tension spring assembly 25 reduces the reset load on the drive component 22 and extends its service life. At the same time, the elastic force of the tension spring 251 keeps the ejector pin 21 stable during movement, avoiding impact caused by the drive component 22 moving too fast and protecting the polarization-maintaining fiber 200 from damage. In addition, the tension spring 251 can also reset the ejector pin 21 by elastic force in the event of a sudden failure of the drive component 22, thereby improving the safety of the polarization-maintaining fiber cutting device 100.

[0030] In one embodiment, the polarization-maintaining fiber cleaving device 100 further includes a cleaving module 3, which includes a cleaving blade 31 and a blade holder 32. The blade holder 32 is movably connected to the base 1, and the cleaving blade 31 is connected to the blade holder 32 and located on the opposite side of the pin module 2 relative to the polarization-maintaining fiber 200.

[0031] The polarization-maintaining fiber cleaving device 100 also includes a cleaving module 3. The cleaving blade 31 of the cleaving module 3 is a diamond blade with extremely high hardness and sharpness. The blade holder 32 is a metal frame structure, movably connected to the base 1 via a sliding mechanism, and can move in a direction perpendicular to the axis of the polarization-maintaining fiber 200. The cleaving blade 31 is fixed to the front end of the blade holder 32 by bolts and is located on the opposite side of the ejector module 2 relative to the polarization-maintaining fiber 200. That is, the ejector 21 and the cleaving blade 31 are respectively located on the upper and lower sides or the left and right sides of the polarization-maintaining fiber 200, forming a counterforce structure. In this embodiment, the ejector 21 and the cleaving blade 31 are respectively located on the left and right sides of the polarization-maintaining fiber 200. When the ejector 21 is in position, an initial scratch is formed on the surface of the polarization-maintaining fiber 200 to ensure that the subsequent polarization-maintaining fiber 200 is broken in a controlled manner at the initial scratch. The blade holder 32 drives the cleaving blade 31 to move towards the fiber. The blade contacts the surface of the fiber and applies pressure. Then, under tension, the fiber breaks along the initial scratch, completing the cleaving. The opposing arrangement of the cutting module 3 and the ejector module 2 ensures that the optical fiber is subjected to symmetrical forces during cutting, avoiding deviation in the cutting angle caused by force offset. The high hardness of the diamond blade ensures uniform scratch depth, reduces end face burrs, and improves cutting quality.

[0032] In one embodiment, the cutting module 3 further includes an adjustment seat 33, which is rotatably connected to the base 1, and the blade holder 32 is detachably connected to the adjustment seat 33 to adjust the pitch angle of the blade holder 32.

[0033] The cutting module 3 also includes an adjustment seat 33, which is rotatably connected to the base 1 via a rotating shaft and can rotate in a vertical plane around the shaft. The blade holder 32 is detachably connected to the adjustment seat 33 by bolts, thereby adjusting the pitch angle of the blade holder 32, i.e., adjusting the angle between the cutting blade 31 and the axis of the polarization-maintaining fiber 200. When fine-tuning of the cutting angle is required, simply rotate the adjustment seat 33 to achieve the fine-tuning of the cutting angle. The setting of the adjustment seat 33 enables the device to adapt to the needs of different cutting angles. The angle adjustment can be precisely achieved through the adjustment seat 33, improving the versatility of the polarization-maintaining fiber cutting device 100. At the same time, the detachable connection method facilitates the maintenance and replacement of the blade holder 32, reducing the operating cost.

[0034] In one embodiment, the cutting module 3 further includes an angle sensor 34 connected to the adjustment seat 33 to detect the pitch angle of the adjustment seat 33 relative to the base 1.

[0035] The cutting module 3 also includes an angle sensor 34, which is a photoelectric encoder. Its rotating shaft is connected to the rotating shaft of the adjusting seat 33 via a coupling, allowing real-time detection of the rotation angle of the adjusting seat 33 relative to the base 1, i.e., the pitch angle of the tool holder 32. The angle sensor 34 is electrically connected to the controller via wires, transmitting the detected angle signal to the controller, which displays the angle value on the display screen for the operator to view. When adjusting the pitch angle of the tool holder 32, the operator can read the current angle value in real time through the display screen. The angle sensor 34 enables digital monitoring of the cutting angle, avoiding the errors caused by traditional angle estimation using a dial, improving the accuracy of angle adjustment, and facilitating the operator to record and reproduce cutting angle parameters, ensuring consistency between different batches of fiber optic cutting.

[0036] In one embodiment, the blade holder 32 has an opening on the side facing the polarization-maintaining fiber 200, and a snap-fit ​​groove is formed in the opening. The cutting blade 31 is snapped into the snap-fit ​​groove. Fixing holes are formed on opposite sides of the opening. The fixing holes are used to insert fasteners to adjust the size of the opening so as to fix the cutting blade 31 on the blade holder 32.

[0037] The blade holder 32 has a rectangular opening on the side facing the polarization-maintaining fiber 200. The width of the opening is slightly larger than the thickness of the cleaver 31. A locking groove is formed along the length of the inner sidewall of the opening, matching the blade body of the cleaver 31. The blade body of the cleaver 31 is secured in the locking groove, with the cutting edge extending from the opening. Coaxial fixing holes are formed on the opposite sidewalls of the opening in the horizontal direction. These fixing holes are threaded holes for inserting fastening bolts. When the cleaver 31 is engaged in the locking groove, tightening the fastening bolt causes the bolt end to press against the sidewall of the opening, reducing the opening width. The friction between the sidewall and the cleaver 31 secures the cleaver 31 to the blade holder 32. When the bolt is loosened, the opening returns to its original state, allowing the cleaver 31 to be removed for replacement or grinding. This fixing structure makes the installation and replacement of the cutting blade 31 more convenient, without the need for special tools. At the same time, the position of the cutting blade 31 can be finely adjusted by adjusting the tightness of the bolts to ensure the alignment accuracy between the blade and the optical fiber. The locking groove prevents the cutting blade 31 from shifting during the cutting process, ensuring cutting stability.

[0038] This utility model also proposes a polarization-maintaining fiber cleaving device, which includes a polarization-maintaining fiber cleaving device 100 and a fixing device for fixing the polarization-maintaining fiber 200. The specific structure of the polarization-maintaining fiber cleaving device 100 is as described in the above embodiments. Since this polarization-maintaining fiber cleaving device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The fixing device is used to fix both ends of the polarization-maintaining fiber 200 and cooperate with the cleaving device to complete the fiber cleaving operation. It is suitable for the processing of polarization-maintaining fiber 200 in factory production lines or laboratories. The fixing device includes two fiber clamps, which are respectively installed on the base 1 and distributed along the axial direction of the polarization-maintaining fiber 200. The pin module 2 and the cleaving module 3 of the cleaving device are located between the two clamps. Each fiber clamp includes a clamping block and a drive motor. The inner side of the clamping block forms a receiving groove that matches the diameter of the polarization-maintaining fiber 200. The drive motor can drive the two clamping blocks to close or open. When closed, the arc-shaped groove clamps the fiber to ensure that the fiber does not move axially during the cleaving process. The fixing device provides stable support and positioning for the optical fiber, ensuring that the optical fiber remains straight during the cutting process and avoiding cutting errors caused by optical fiber bending. At the same time, the clamping force of the pneumatic clamp is adjustable, which is suitable for polarization-maintaining optical fibers of different diameters, thus improving the adaptability of the polarization-maintaining optical fiber cutting equipment.

[0039] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model.
