Description

Technical Field

[0001] This application relates to the field of optical fiber processing technology, specifically to cutting components, optical fiber cutting devices, and cutting methods. Background Technology

[0002] In the manufacturing process of fiber optic imaging components, the secondary multifiring process is one of the core technological steps. The specific process of the secondary multifiring process is as follows: first, single fiber filaments are drawn into fiber multifiring through multiple regular arrangements; then, multiple fiber multifirings are arranged, cut, and assembled. This process requires cutting and separating the drawn fiber multifirings to a fixed length according to process requirements, providing multifiring segments that meet dimensional requirements for subsequent board layout and assembly processes. Cutting is a critical step in the secondary multifiring process; the continuously drawn fiber multifirings must be cut to a preset length. The cutting quality directly determines the flatness of the fiber multifiring end face, thus affecting the optical performance of the final fiber optic imaging component.

[0003] Traditional cutting methods rely heavily on manual cutting. During manual cutting, it is difficult to precisely control process parameters such as force, angle, and speed, resulting in poor consistency of the cut end face quality and defects such as tilting, burrs, cracks, and chipping.

[0010] According to one embodiment of this application, it is used to make grooves on the surface of an optical fiber.

[0011] According to another embodiment of this application, an optical fiber cleaving apparatus includes: the cleaving component described above; a fixing component including a first pressing block and a first bearing block, the first bearing block being used to carry an optical fiber and the first pressing block being used to press down and fix the optical fiber; and a moving component including a second pressing block, a second bearing block, and a first driving member, the second bearing block being used to carry an optical fiber and the second pressing block being used to press down and fix the optical fiber, and the first driving member being used to drive the moving component away from or towards the fixing component; wherein the position where the first bearing block contacts and carries the optical fiber is on the same horizontal plane as the position where the second bearing block contacts and carries the optical fiber, and there is a gap between the fixing component and the moving component to allow the cleaving blade to enter and cut the optical fiber.

[0012] According to another embodiment of this application, the bearing surface on the first bearing block and the bearing surface on the second bearing block for carrying optical fibers are both arranged with a plurality of grooves formed by two intersecting inclined surfaces.

[0013] According to another embodiment of this application, the fixing component further includes a first pressure sensor for measuring the pressure exerted by the first pressure block on the optical fiber; the moving component further includes a second pressure sensor for measuring the pressure exerted by the second pressure block on the optical fiber.

[0014] According to another embodiment of this application, the fixed component further includes a second driving member for driving the first pressure block to press down the optical fiber; the moving component further includes a third driving member for driving the second pressure block to press down the optical fiber.

[0015] According to another embodiment of this application, the fiber optic cleaving device includes the following steps: placing one end of the fiber to be cleaved on a first support block; placing the other end of the fiber to be cleaved on a second support block; driving a first pressure block to press down and fix the fiber, and driving a second pressure block to press down and fix the fiber; adjusting a telescopic member so that its telescopic end extends or retracts axially to limit the minimum limit position when the cutter head rotates; activating a cleaving blade drive to drive the cleaving blade to move to the gap to cut the fiber and form a groove on the fiber surface; activating the first drive to drive a motion assembly to move horizontally away from the fixed assembly so that the motion assembly applies a horizontal tensile force to the fiber and pulls the fiber apart along the groove; releasing the first and second pressure blocks from fixing the fiber; and removing the fiber.

Conversely, upon encountering a convex area, the cutting blade, along with the mounting component, adaptively rotates a certain angle away from the object, thereby causing the cutting head to rise relative to the previously traversed cutting path to accommodate the convex section of the cutting path. The telescopic component limits the lowest position of the cutting head's rotation, ensuring it is flush with the lowest point of the object's cutting surface when it varies, thus ensuring the cutting head always conforms to the contour of the cutting surface. Therefore, the cutting head can adapt to uneven cutting surfaces on different objects, and the cutting assembly of this application is suitable for various cutting fields, particularly for scoring and marking optical fiber multifilaments.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0026] One embodiment of this application discloses a cutting component; please refer to [link / reference needed]. Figure 1 The cutting assembly includes a cutting blade 100, a mounting member 300, and a cutting blade drive member 200. The cutting blade 100 has a cutting head 110 for cutting objects. The cutting blade 100 is mounted on the cutting blade drive member 200 via the mounting member 300. When the cutting blade drive member 200 is activated, it can drive the mounting member 300 and the cutting blade 100 to move, thereby cutting the object.

[0027] Understandably, in Figure 1 In a specific embodiment, the cutting blade drive unit 200 includes a first drive base 210, on which a first guide rail 240 is arranged in a horizontal direction. Specifically, the first guide rail 240 is arranged in the X-axis direction. Correspondingly, a first slider 230 is arranged on the first guide rail 240, which cooperates with the first guide rail 240 and can slide along the first guide rail 240. The cutting blade 100 is mounted on the first slider 230 through a mounting member 300. In order to drive the first slider 230 to move along the first guide rail 240, the first slider 230 is provided with a threaded through hole in a horizontal direction. The cutting blade drive unit 200 also includes a first motor 250 and a first stud. The first stud extends into the threaded through hole to be threadedly connected to the first slider 230. The first stud is arranged in a horizontal direction and parallel to the first guide rail 240. One end of the first stud is coaxially arranged with the output end of the first motor 250, and the other end is rotatably connected to the first drive base 210. Therefore, by starting the first motor 250, the first stud is driven to rotate around the axis, and the first slider 230 slides along the first guide rail 240 under the rotation drive of the first stud, so that the mounting part 300 and the cutting blade 100 can move along the first guide rail 240, so that the cutting head 110 of the cutting blade 100 can cut the objects along the way.

[0028] It should be noted that the structure by which the cutting blade drive unit 200 drives the cutting blade 100 to move horizontally is not limited to the aforementioned lead screw and guide rail combination structure. For example, the cutting blade drive unit 200 can also be a gear and rack combination structure, in which the cutting blade 100 is mounted on the rack via a mounting base, the rack is embedded in a guide groove, and the output end of the motor is coaxially connected to the gear via a coupling. The gear meshes with the rack, and thus, by starting the motor, the gear is driven to rotate, thereby causing the rack to move along the guide groove, thus realizing the movement of the cutting blade 100. Of course, the cutting blade drive unit 200 can also have other structures, which will not be elaborated here.

[0029] Understandably, in traditional structures, the cutting blade 100 is either a mechanical cutting blade 100 or an ultrasonic cutting blade 100. The cutting blade 100 needs to contact the surface of the object to cut it. If the surface of the object to be cut is uneven, the cutting blade 100, cutting along a predetermined path, is easily affected by the unevenness of the surface. This can result in incomplete cutting of concave areas and breakage of convex areas due to excessive pressure from the cutting blade head 110, leading to defects such as cracks and burrs. Therefore, the cutting quality is difficult to guarantee. Thus, as... Figure 2 As shown, the mounting component 300 also includes a rotating component 330, which is formed as a bearing. The first slider 230 is correspondingly provided with a bearing rod. The mounting component 300 is connected to the bearing rod of the first slider 230 through the bearing, so that the mounting component 300 can rotate relative to the first slider 230. It is worth noting that the axes of the bearing rod and the bearing are both located in the horizontal plane and perpendicular to the first screw 220 and the first guide rail 240. Therefore, during the process of the cutting blade 100 driving assembly driving the cutting blade 100 to cut the object, the cutting blade 100 can rotate around the axis in the vertical plane.

[0030] By adopting the design that allows the cutting blade 100 to rotate around the axis of the rotating component 330, the cutting head 110 of the cutting blade 100 can adapt to the shape of the cutting surface when cutting along the cutting path. When encountering a concave area, the cutting blade 100 adapts to the direction closer to the object with the mounting component 300, thereby causing the cutting head 110 of the cutting blade 100 to sink relative to the previously passed cutting path to adapt to the concave section in the cutting path. When encountering a convex area, the cutting blade 100 adapts to the direction away from the object with the mounting component 300, thereby causing the cutting head 110 of the cutting blade 100 to rise relative to the previously passed cutting path to adapt to the convex section in the cutting path. Thus, the cutting head 110 of the cutting blade 100 can adapt to the uneven cutting surface on the object.

[0031] Furthermore, such as Figure 1 and Figure 2As shown, the cutting assembly also includes a telescopic member 400, which is fixed to the first slider 230. The telescopic member 400 includes a telescopic end 411, which abuts against the mounting member 300. The telescopic end 411 can extend and retract along its axial direction to limit the lowest limit position of the cutter head 110 when it rotates with the mounting member 300.

[0032] In other words, the telescopic member 400 is used to limit the angle of rotation of the mounting member 300 about the axis. Specifically, in this application... Figure 1 In a specific embodiment, the telescopic end 411 of the telescopic member 400 abuts against one side of the mounting member 300 in a vertical direction. It can be understood that the position where the telescopic end 411 abuts against the mounting member 300 is offset from the axis of rotation of the rotating member 330 on the mounting member 300. The telescopic end 411 can thus control the rotation of the mounting member 300 around the axis by extending or shortening, thereby controlling the posture of the cutting blade 100 fixedly connected to the mounting member 300.

[0033] by Figure 1 and Figure 2 For example, the cutting blade 100 can rotate with the mounting component 300 on the first slider 230. This means the cutting blade 100 rotates in the XZ plane. The cutting head 110 of the cutting blade 100 is located at its lower end. Specifically, it rotates clockwise and counterclockwise. The X-axis arrow points in the direction in which the cutting blade 100 moves to cut the object. The telescopic end 411 of the telescopic component 400 abuts against the rear end of the mounting component 300 on the X-axis from top to bottom. When the telescopic component 400 extends, it causes the cutting head 110 of the cutting blade 100 to rotate in the direction of the cutting path, i.e., the cutting head 110 rotates clockwise. When the cutting blade 100 is shortened by 400, the cutting head 110 of the cutting blade 100 rotates backward in the opposite direction to the cutting path, that is, the cutting head 110 rotates counterclockwise. In this embodiment, the height of the cutting head 110 increases when it rotates clockwise and decreases when it rotates counterclockwise. Since the telescopic end 411 of the telescopic member 400 is above and behind the mounting member 300, the counterclockwise rotation of the mounting member 300 and the cutting blade 100 is restricted by the telescopic member 400. Thus, the telescopic member 400 limits the lowest position of the rotation of the cutting head 110 of the cutting blade 100 and aligns it with the lowest point when the object cutting surface undulates, thereby ensuring that the cutting head 110 always conforms to the contour of the cutting surface.

[0034] It is understandable that, such as Figure 2As shown, the aforementioned telescopic component 400 is formed as a differential head, which includes a differential cylinder 420, a sleeve, and a telescopic rod 410. The telescopic component 400 is fixedly connected to the first slider 230 through the sleeve. One end of the telescopic rod 410 is fixedly connected to the differential cylinder 420, and the other end serves as the telescopic end 411 of the telescopic component 400, abutting against the mounting component 300. The telescopic rod 410 is formed as a lead screw, and the inner hole of the sleeve has a thread matching the lead screw. The telescopic rod 410 is threaded into the inner hole of the sleeve. The differential cylinder 420, the sleeve, and the telescopic rod 410 are coaxially arranged. Thus, by rotating the differential cylinder 420, the telescopic rod 410 is driven to move axially along the sleeve, thereby controlling the extension length of the telescopic end 411 to achieve adjustment of the minimum limit position of the cutter head 110. Of course, the telescopic component 400 can also adopt other linearly telescopic actuators such as pneumatic push rods or electric push rods, as long as it can ensure that the mechanical displacement is converted into adjustment of the attitude of the cutter head 110.

[0035] In some embodiments, see Figure 1 and Figure 2 The mounting component 300 includes a first mounting block 310 and a second mounting block 320. A rotating component 330 is disposed on the first mounting block 310. The first mounting block 310 and the second mounting block 320 are close to each other and can clamp the cutting blade 100. The first mounting block 310 and the second mounting block 320 are connected by bolts. The first mounting block 310 and the second mounting block 320 can clamp the cutting blade 100 at different positions along the length direction of the cutting blade 100.

[0036] In other words, the position of the cutting blade 100 fixed to the mounting member 300 can be changed as needed. The first mounting block 310 and the second mounting block 320 clamp the cutting blade 100 at different positions along the length of the cutting blade 100, so that the mounting reference point of the cutting blade 100 can be changed along the length of the cutting blade 100. Since the cutting blade 100 is rotatably connected to the first slider 230 through the mounting member 300, as the position of the cutting blade 100 installed on the mounting member 300 changes, the contact pressure that one end of the cutting head 110 on the object cutting surface can be applied changes accordingly. When the mounting member 300 clamps the end of the cutting blade 100 away from the cutting head 110, the distance from the cutting head 110 to the mounting member 300 is longer, that is, the lever arm is longer, and the contact pressure of the cutting head 110 on the object cutting surface is also greater. Conversely, when the clamping position of the mounting member 300 is closer to the cutting head 110, the lever arm is shortened and the contact pressure is reduced. Therefore, based on the structure where the cutting blade 100 is rotatably connected to the first slider 230 via the mounting component 300, the cutting pressure of the blade head 110 can be adjusted by adjusting the clamping positions of the first mounting block 310 and the second mounting block 320 in the length direction of the cutting blade 100, so as to adapt to the cutting requirements of different materials and thicknesses and improve the processing accuracy and surface quality.

[0037] In some embodiments, the cutting assembly of this application is used to score the surface of an optical fiber. It is understood that when cutting optical fibers using contact cutting methods such as mechanical or ultrasonic cutting, the cutting force and angle are difficult to control precisely, resulting in poor consistency of the fiber end face quality and defects such as tilting, burrs, cracks, and edge chipping. This application, by introducing the aforementioned rotatable mounting component 300 and cutting blade 100, enables the blade head 110 to adapt to the undulations of the fiber's outer surface when in contact with it, adaptively adjusting the blade head 110's tilt angle and height to cut the fiber in close contact with its surface. By changing the position of the mounting component 300 holding the cutting blade 100, the cutting pressure that the blade head 110 can apply to the fiber surface is further adjusted. Therefore, by cutting the optical fiber using the cutting assembly of this application, the fiber surface can be precisely and closely cut with appropriate cutting pressure, avoiding rigid collisions between the cutting blade 100 and the fiber surface, reducing end face defects such as burrs and cracks, and improving the consistency and stability of the cutting quality.

[0038] Another embodiment of this application discloses an optical fiber cleaving device; please refer to [link to relevant documentation]. Figure 1 It includes the aforementioned cutting assembly and base 700. The base 700 is provided with a mounting post 710, which extends vertically. The cutting blade drive 200 of the cutting assembly is fixedly installed on the top of the mounting post 710. Specifically, the cutting blade drive 200 is installed on the mounting post 710 horizontally via a first drive seat 210.

[0039] like Figure 1 As shown, the fiber optic cleaving device also includes a fixing component 500 and a moving component 600. The fixing component 500 includes a first support block 520, and the moving component 600 includes a second support block 620. The two are disposed opposite each other on the base 700. There is a gap between the first support block 520 and the second support block 620 to allow the cleaving blade 100 of the cleaving component to be driven and enter. Both the first support block 520 and the second support block 620 are used to support the fiber multifilament 10, which is composed of multiple fiber monofilaments. The two ends of the fiber multifilament 10 are respectively placed on the first support block 520 and the second support block 620. On the carrier block 620; the fixing component 500 also includes a first pressing block 510, and the moving component 600 also includes a second pressing block 610. The first pressing block 510 and the second pressing block 610 are respectively raised and lowered above the first carrier block 520 and the second carrier block 620, and are respectively used to press the two ends of the optical fiber multifilament 10; the moving component 600 also includes a second driving member 540 that drives the moving component 600 to translate along the direction close to or away from the fixing component 500. It is worth noting that the translation path is perpendicular to the cutting path to ensure that the optical fiber multifilament 10 maintains stable tension during the cutting process.

[0040] Understandably, multiple fiber optic multifilaments 10 are placed at both ends on the first support block 520 and the second support block 620, respectively. The multiple fiber optic multifilaments 10 are arranged side by side along the cutting path to form a fiber optic group. Then, the first pressure block 510 and the second pressure block 610 are pressed down to stabilize the position of the fiber optic multifilaments 10. Subsequently, the first motor 250 in the cutting blade drive unit 200 is started so that the cutting blade 100 enters the gap along the cutting path and makes a groove on the surface of the fiber optic multifilament group 10. Then, the second drive unit 540 of the motion component 600 drives the second support block 620 to move away from the fixed component 500, so that the fiber optic multifilament group 10 breaks neatly at the groove under constant tension, thus completing the entire fiber optic multifilament 10 cutting process.

[0041] Further, please see Figure 3 and Figure 4 The bearing surfaces of the first bearing block 520 and the second bearing block 620, which are used to support the optical fiber multifilament 10, are both arranged with multiple grooves formed by two intersecting inclined surfaces. It can be understood that... Figure 3 The first carrier block 520 and Figure 4 The second carrier block 620 in the same structure has multiple grooves formed by two intersecting inclined surfaces on its carrier surface for carrying the optical fiber multifilament 10, so as to place the optical fiber multifilament 10.

[0042] It is worth noting that the radial cross-section of the fiber multifilament 10 is a regular hexagon, and the angle between the two intersecting inclined surfaces of the grooves in the first support block 520 and the second support block 620 is 120°. When the fiber multifilament 10 is placed on the groove, the side edges of the fiber multifilament 10 are positioned at the top of the fiber multifilament 10. Therefore, please refer to... Figure 1 It is understood that when the cleaver 100 makes scratches on the optical fiber multifilament 10, the contact area between the cleaver tip 110 and the optical fiber multifilament 10 will be reduced, thereby minimizing the wear of the optical fiber multifilament 10.

[0043] In some embodiments, such as Figure 1As shown, the fixing component 500 also includes a first pressure sensor 530 and a second drive member 540. The first pressure sensor 530 is used to measure the pressure applied by the first pressure block 510 to the optical fiber, and the second drive member 540 is used to drive the first pressure block 510 to press down on the optical fiber. The moving component 600 also includes a second pressure sensor 630 and a third drive member 650. The second pressure sensor 630 is used to measure the pressure applied by the second pressure block 610 to the optical fiber, and the third drive member 650 is used to drive the second pressure block 610 to press down on the optical fiber. Understandably, the first pressure sensor 530 is disposed between the first pressure block 510 and the second driving member 540. When the second driving member 540 presses down on the first pressure block 510, the first pressure sensor 530 senses the clamping pressure of the first pressure block 510 on the optical fiber in real time. The second pressure sensor 630 is disposed between the second pressure block 610 and the third driving member 650. When the third driving member 650 presses down on the second pressure block 610, the second pressure sensor 630 senses the clamping pressure of the second pressure block 610 on the optical fiber in real time. Each pressure sensor and each driving member is electrically connected to the controller (not shown in the figure) of the optical fiber cutting device.

[0044] In other words, the required pressure varies depending on the specifications of the fiber multifilament 10. For example, when cutting a fiber multifilament 10 with an opposite side diameter of 1mm, a pressure of 200N is required. When the first pressure sensor 530 and the second pressure sensor 630 detect that the pressure exceeds 200N, they will send an overpressure signal to the controller. The controller will then control the second drive unit 540 and the third drive unit 650 to stop pressing down and retract appropriately to adjust the clamping pressure to a preset reasonable range. This prevents deformation of the fiber multifilament 10 or micro-cracks on its surface due to excessive compression, ensuring the stability of the subsequent cutting process and the quality of the fiber end face. In addition, the controller can dynamically adjust the output force of the drive unit based on the real-time data from the pressure sensors to improve the cutting consistency of the cutter 100.

[0045] In some embodiments, such as Figure 1As shown, the fiber optic cutting device also includes a first driving member 640, which drives the motion component 600 to move closer to or away from the fixed component 500. The motion component 600 includes a second slider 643 and a second guide rail 642. The second guide rail 642 is disposed on the base 700, with one end close to the fixed component 500 and the other end away from the fixed component 500. The second slider 643 is disposed below the second support block 620 of the motion component 600. Thus, the support block can slide along the second guide rail 642 under the action of the second slider 643 to move closer to or away from the fixed component 500. Specifically, the first driving component 640 also includes a second motor (not shown in the figure) and a second screw 641. One end of the second screw 641 is fixedly connected to the output end of the second motor, and the other end is threadedly connected to the second bearing block 620. Driving the output end of the second motor to rotate can drive the second bearing block 620 to slide along the second guide rail 642 to move away from or closer to the fixed component 500. It can be understood that by adjusting the forward and reverse rotation of the output end of the second motor, it is possible to adjust whether the moving component 600 is away from or closer to the fixed component 500.

[0046] This application also discloses a fiber optic cleaving device and cleaving method. Please refer to [link to relevant documentation]. Figures 1 to 4 Using the aforementioned fiber optic cleaving device, the following steps are included: placing one end of the fiber to be cleaved in the groove on the first support block 520; placing the other end of the fiber to be cleaved in the groove on the second support block 620; setting the pressing pressure of the first pressure block 510 and the second pressure block 610 according to the specifications of the fiber to be cleaved; driving the first pressure block 510 to press down and fix the fiber, and driving the second pressure block 610 to press down and fix the fiber; adjusting the telescopic member 400 so that its telescopic end 411 extends or retracts axially to limit the lowest limit position when the cutter head 110 rotates; starting the cleaving blade drive member 200 to drive the cleaving blade 100 to move to the gap to cut the fiber and form a groove on the fiber surface; starting the first drive member 640 to drive the motion component 600 to move horizontally away from the fixing component 500 so that the motion component 600 applies a horizontal tensile force to the fiber and pulls the fiber apart along the groove; driving the first pressure block 510 and the second pressure block 610 to move upward to release the first pressure block 510 and the second pressure block 610 from fixing the fiber; and removing the fiber.

[0047] In some embodiments, after the first pressure block 510 and the second pressure block 610 are driven to press down and fix the optical fiber, the first driving member 640 is activated to drive the motion component 600 away from the fixing component 500 so that the optical fiber maintains a stable tension state, thereby ensuring that the tension of all parallel optical fiber multifilaments 10 is uniform and consistent, providing a stable foundation for subsequent scoring and breakage steps, and further improving the flatness and consistency of the cut end face.
