Abstract
Description
Technical Field
[0001] This invention relates to the field of optical fiber technology, and specifically to an optical fiber slitting and cutting device and method. Background Technology
[0002] Optical fiber is a commonly used component in optical communication equipment. The process of handling optical fiber involves first slitting the rolled fiber into sections for transport and subsequent steps. Traditionally, this is done manually by pulling the fiber and cutting it with a cleaver. This fully manual operation easily damages the fiber, and the finished fiber length cannot be guaranteed, leading to scrap and low efficiency.
[0003] To solve the above problems, especially for cutting longer optical fibers, it is necessary to straighten the fibers before cutting them. To achieve the required precision, a fully automated mechanism is needed to cut the optical fibers, which will facilitate transportation and subsequent processing. Existing manual operations or mechanisms cannot achieve this. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an optical fiber slitting and cutting device and method to automatically cut optical fibers into structures of specified lengths.
[0005] To achieve the above objectives, the technical solution of this invention is as follows:
[0006] An optical fiber slitting and unloading device includes a vertical plate and a frame. The vertical plate is mounted on a workbench, and the frame is mounted on the side of the workbench. Along the optical fiber conveying direction, the vertical plate is equipped with an optical fiber storage mechanism, an optical fiber positioning and guiding mechanism, an optical fiber conveying mechanism, and an optical fiber cutting mechanism. An automatic fiber pulling mechanism is mounted on the frame. The optical fiber positioning and guiding mechanism is used to adjust the height of the optical fiber and limit its horizontal position. The optical fiber conveying mechanism is used to push the optical fiber forward. The optical fiber cutting mechanism is used to cut the optical fiber. The automatic fiber pulling mechanism includes an optical fiber clamping assembly and an optical fiber moving assembly, with the clamping assembly connected to the moving assembly.
[0007] Furthermore, the optical fiber storage mechanism includes an optical fiber disk, which is connected to a first motor via a rotating shaft. One end of the first motor includes a motor base, which is fixed to a vertical plate by bolts. The other end of the first motor is connected to one end of the rotating shaft, and the other end of the rotating shaft is fixedly connected to the optical fiber disk. The first motor drives the rotating shaft to rotate, and the optical fiber disk rotates together with the rotating shaft.
[0008] Furthermore, an adaptive tensioning guide mechanism, a second guide wheel, and a first guide wheel are sequentially arranged between the optical fiber storage mechanism and the optical fiber positioning guide mechanism along the optical fiber transmission direction. The adaptive tensioning guide mechanism, the second guide wheel, and the first guide wheel are mounted on the upright plate to receive the optical fiber.
[0009] Furthermore, the adaptive tensioning guide mechanism includes a bracket fixed to the upright plate, one end of the swing arm shaft is hinged to the bracket, the other end of the swing arm shaft is fixedly connected to one end of the swing arm, the other end of the swing arm is fixedly connected to the idler wheel bracket, the idler wheel bracket is connected to the idler wheel, the idler wheel is used to support the optical fiber, one end of the spring is connected to the middle of the swing arm, the other end of the spring is connected to the tension sensor, and the tension sensor is fixed to the bracket by a mounting base.
[0010] Furthermore, the fiber optic positioning and guiding mechanism includes a fiber optic positioning and guiding mechanism base mounted on the upright plate. A centering cylinder and a roller fixing block are fixedly mounted on the surface of the fiber optic positioning and guiding mechanism base. The centering cylinder is vertically mounted on the surface of the vertical lifting mechanism, and the roller fixing block is horizontally mounted at the lower part of the surface of the fiber optic positioning and guiding mechanism base, perpendicular to the mounting base surface. The centering cylinder is located above the roller fixing block. The drive end of the centering cylinder is connected to two vertically arranged pneumatic claws, each connected to a roller, namely a first positioning roller and a second positioning roller, which are vertically arranged. A first fixing roller and a second fixing roller are vertically mounted on the upper surface of the roller fixing block, which are horizontally arranged.
[0011] Furthermore, the optical fiber transmission mechanism includes a second motor, the drive end of which is connected to an active pulley. The active pulley is connected to a driven pulley via a first transmission belt. The driven pulley is coaxially connected to a first transmission roller. The first and second transmission rollers are respectively fixed on the two drive ends of the roller gripper. The optical fiber is located between the first and second transmission rollers. The movement of the first and second transmission rollers rubs against the optical fiber, causing it to be transmitted forward.
[0012] Furthermore, the optical fiber cutting mechanism includes a cutting gripper, the drive end of which is connected to a front cutter and a rear cutter arranged in a front-to-back manner. The cutting gripper is used to drive the front cutter and the rear cutter to move. When the optical fiber is located between the front cutter and the rear cutter, the front cutter and the rear cutter move relative to each other to cut the optical fiber.
[0013] Furthermore, the automatic fiber pulling mechanism includes an optical fiber clamping assembly and an optical fiber moving assembly. The optical fiber clamping assembly includes a cam elastic pressure head assembly and a multi-link clamping assembly. The cam elastic pressure head assembly includes a cam rod assembly and an elastic push rod mechanism.
[0014] The cam rod assembly includes a cam rod and a first rotating shaft. The first rotating shaft is connected between two side plates. The bottom ends of the two side plates are connected to a back plate, which is set vertically downward and is connected to the fiber optic moving assembly.
[0015] The cam rod is hinged to the first rotating shaft;
[0016] The elastic push rod mechanism includes a top plate, a spring, and a guide mechanism. Both the top plate and the guide mechanism are horizontal plates, arranged vertically. The top end of the vertical connecting rod is connected to the lower surface of the top plate, and the lower end of the connecting rod passes through the guide mechanism. After the lower end of the connecting rod extends out from the guide mechanism, the bottom end of the connecting rod is connected to the first horizontal connecting rod. The end of the cam rod is connected to the upper surface of the top plate. The spring is wound around the upper part of the connecting rod and is located between the top plate and the guide mechanism. The top end of the spring is connected to the bottom surface of the top plate. The upper part of the connecting rod is in clearance fit with the top plate, allowing the top plate to slide up and down along the upper part of the connecting rod. The connecting rod is in clearance fit with the guide mechanism, allowing the lower part of the connecting rod to slide up and down along the guide mechanism.
[0017] A second link is connected to the upper surface of each side of the first link. One end of the second link is hinged to the upper surface of the two sides of the first link, and the other end is hinged to the top of the third link. The third link is hinged to the second rotation shaft. A clamp is connected to the lower part of each of the two third links. The end of the clamp is connected to the lower part of the inner side of one of the third links, and the top of the clamp faces the other third link. The optical fiber can be clamped between the tops of the two clamps.
[0018] Furthermore, the fiber optic moving assembly includes a third motor and a mounting block, with the third motor mounted on the frame;
[0019] A material trough is provided on the frame, the length of which is longer than the length of the frame. One end of the material trough extends above the bottom plate. A limit block is fixedly provided on the upper surface of the side of the material trough located above the bottom plate. There is a notch at the lower part of the side of the material trough located above the bottom plate. A third motor is provided at the notch. The third motor is located on the material trough, which is a groove. The third motor is supported by the bottom surface of the groove. The third motor is connected to the driving wheel, and the driving wheel is connected to the driven wheel through a second transmission belt.
[0020] The mounting block is installed on the second transmission belt. The third motor rotates forward or reverse to drive the mounting block to move back and forth with the second transmission belt. The mounting block is connected to the mounting base. The back plate of the fiber optic clamping assembly is fixed on the mounting base. When the third motor rotates, the fiber optic clamping assembly moves back and forth with the mounting block. When the mounting block moves toward the storage cabinet, the cam rod collides with the limiting block, and the top of the cam rod is pressed down by the limiting block.
[0021] A method for slitting and cutting optical fibers using the aforementioned optical fiber slitting and cutting device:
[0022] The optical fiber is wound on the optical fiber reel of the optical fiber storage mechanism. The end of the optical fiber on the optical fiber storage mechanism passes sequentially around the idler wheel, the second guide wheel and the first guide wheel. Then the end of the optical fiber extends from the first guide wheel to the optical fiber adjustment guide mechanism. The end of the optical fiber passes sequentially between the first fixed roller and the second fixed roller and between the first adjustment roller and the second adjustment roller. The optical fiber then passes between the first transfer roller and the second transfer roller. With the cleaver gripper not working, the optical fiber passes sequentially between the front cleaver and the rear cleaver and between the two clamps. The two clamps hold the optical fiber. The first motor and the second motor work to drive the end of the optical fiber to extend forward in the material groove. The third motor works to drive the mounting block to move away from the limit block, so that the automatic fiber pulling mechanism holds the end of the optical fiber and drives the optical fiber to move forward along the material groove.
[0023] When the fiber reaches the set length, the first, second, and third motors stop working, and the cutting gripper cuts the fiber. After the fiber is cut, the third motor drives the mounting block to move closer to the limit block. When the cam rod hits the limit block, the two clamps open, and the fiber falls into the trough.
[0024] The beneficial effects of this invention are:
[0025] The optical fiber unloading method of this invention uses an adaptive tensioning and guiding mechanism to adaptively tension and guide the optical fiber conveyed from the optical fiber storage mechanism. The horizontal position and height of the optical fiber are adjusted by the optical fiber positioning and guiding mechanism to align the optical fiber with the optical fiber transmission mechanism. The optical fiber transmission mechanism conveys the optical fiber, and the automatic fiber pulling mechanism clamps the optical fiber head and transmits it synchronously, so that the optical fiber does not rub against other guiding devices and ensures that the surface of the optical fiber is free of scratches. The optical fiber clamping component in the automatic fiber pulling mechanism is a non-powered, purely mechanical clamping mechanism, which avoids the drawbacks of long-distance use of cables or air tubes. It is particularly suitable for unloading long and thick optical fibers. Except for the manual operation when the optical fiber is led out from the optical fiber storage mechanism to the automatic fiber pulling mechanism, all other processes can be completed automatically, which greatly improves production efficiency.

[0038] To make the purpose, technical solution, and advantages of the invention clearer, the invention will be further described below with reference to the accompanying drawings.
[0039] like Figure 1 As shown, an optical fiber slitting and unloading device includes a workbench 12, with a storage cabinet 12-1 at the bottom. The top surface of the storage cabinet is a bottom plate 10. The workbench 12 includes a top plate 12-2, which is parallel to the bottom plate 10. A side plate 12-3 is located between the top plate 12-2 and the bottom plate 10, and is perpendicular to both the top plate 12-2 and the bottom plate 10. The top end of the side plate 12-3 is connected to the end of the top plate 12-2, and the bottom end of the side plate 12-3 is connected to the bottom end of the top plate 12-2. At the end of the connecting base plate 10, the bottom surface of the top plate 12-2 opposite to the side plate 12-3 is provided with a control panel 12-4. The control panel 12-4 is electrically connected to the first motor 11-3, the centering cylinder 5-8, the second motor 4-1, the cutting gripper 3-1, and the third motor 2-19. The control panel 12-4 is used to control the operation of the first motor 11-3, the centering cylinder 5-8, the second motor 4-1, the cutting gripper 3-1, and the third motor 2-19.
[0040] A vertical plate 1 is vertically arranged on the surface of the base plate 10. Along the fiber conveying direction, the vertical plate 1 is respectively provided with a fiber storage mechanism 11, an adaptive tensioning guide mechanism 8, a second guide wheel 7, a first guide wheel 6, a fiber positioning guide mechanism 5, a fiber transmission mechanism 4, and a fiber cutting mechanism 3. The right side of the storage cabinet 12-1 is fixedly connected to the side of the frame 9. The frame 9 is a square body and is provided with an automatic fiber pulling mechanism 2.
[0041] like Figure 2 As shown, the optical fiber storage mechanism 11 includes an optical fiber disk 11-1, which is connected to a first motor 11-3 via a rotating shaft 11-2. The optical fiber is wound on the optical fiber disk 11-1. One end of the first motor 11-3 includes a motor base, which is fixed to the upright plate 1 by bolts to fix the optical fiber storage mechanism 11 on the upright plate 1. The other end of the first motor 11-3 is connected to one end of the rotating shaft 11-2, which is splined to the motor. The other end of the rotating shaft 11-2 is fixedly connected to the optical fiber disk 11-1. The first motor 11-3 drives the rotating shaft 11-2 to rotate, and the optical fiber disk 11-1 rotates together with the rotating shaft 11-2.
[0042] like Figure 1 and Figure 3 As shown, the upright plate 1 is also equipped with an adaptive tensioning and guiding mechanism 8, which is used to adaptively tension and guide the optical fiber delivered from the optical fiber storage mechanism 11, such as... Figure 3As shown, the adaptive tensioning guide mechanism 8 includes a bracket 8-1 fixed on the upright plate 1. The bracket 8-1 is fixed to the upright plate 1 by bolts. A swing arm shaft 8-7 is hinged to the bracket 8-1. The swing arm shaft 8-7 can rotate around the bracket 8-1. One end of the swing arm shaft 8-7 is hinged to the bracket 8-1, and the other end of the swing arm shaft 8-7 is fixedly connected to one end of the swing arm 8-4. The other end of the swing arm 8-4 is fixedly connected to the idler wheel bracket 8-2. The idler wheel bracket 8-2 is rectangular in shape. An idler wheel 8-3 is connected to the idler wheel bracket 8-2. The idler wheel 8-3 is fitted on the top edge of the rectangle. The idler wheel 8-3 is similar to the structure of the fiber optic disc 11-1. The idler wheel 8-3 is used to support the optical fiber. One end of the spring 8-6 is connected to the middle of the swing arm 8-4. The other end of the spring is connected to the tension sensor 8-5. The tension sensor 8-5 is fixed to the bracket 8-1 by a mounting base.
[0043] A second guide wheel 7 and a first guide wheel 6 are also provided between the adaptive tensioning guide mechanism 8 and the optical fiber positioning guide mechanism 5. The second guide wheel 7 and the first guide wheel 6 are similar to the structure of the optical fiber disk 11-1. The second guide wheel 7 and the first guide wheel 6 are used to receive optical fibers.
[0044] like Figure 4As shown, the fiber optic positioning guide mechanism 5 is used to adjust the height of the fiber optic cable and limit its horizontal position. The fiber optic positioning guide mechanism 5 includes a fiber optic positioning guide mechanism base 5-1, the bottom of which is fixed to the vertical plate 1 by bolts. A centering cylinder 5-8 and a roller fixing block 5-7 are fixedly mounted on the surface of the fiber optic positioning guide mechanism base 5-1. The centering cylinder 5-8 is vertically mounted on the surface of the vertical lifting mechanism 5-1, and the roller fixing block 5-7 is horizontally mounted at the lower part of the surface of the fiber optic positioning guide mechanism base 5-1. The roller fixing block 5-7 is a horizontal plate and is perpendicular to the surface of the mounting base 5-1. The centering cylinder 5-8 is located above the roller fixing block 5-7. The drive end of the centering cylinder 5-8 is connected to two vertically arranged pneumatic claws 5-2, each connected to a roller, namely the first positioning roller 5-3 and the second positioning roller 5-4. -4. The first adjusting roller 5-3 and the second adjusting roller 5-4 are arranged vertically. The pneumatic gripper 5-2 can drive the first adjusting roller 5-3 or the second adjusting roller to move. Under the drive of the two pneumatic grippers 5-2 of the centering cylinder 5-8, the first adjusting roller 5-3 and the second adjusting roller 5-4 can move upward at the same time, or move downward at the same time, or one adjusting roller moves upward and the other adjusting roller moves downward, so that the distance between the first adjusting roller 5-3 and the second adjusting roller 5-4 can be adjusted. The adjustable distance between the first adjusting roller 5-3 and the second adjusting roller 5-4 makes it easy to place the optical fiber between the two adjusting rollers or remove the optical fiber from between the two adjusting rollers. The first fixing roller 5-5 and the second fixing roller 5-6 are vertically arranged on the upper surface of the roller fixing block 5-7, and the first fixing roller 5-5 and the second fixing roller 5-6 are arranged horizontally. The optical fiber passes sequentially between the first fixed roller 5-5 and the second fixed roller 5-6, and between the first adjusting roller 5-3 and the second adjusting roller 5-4. The horizontal and vertical positions of the optical fiber are defined and adjusted by the first adjusting roller 5-3 and the second adjusting roller 5-4 arranged vertically and the first fixed roller 5-5 and the second fixed roller 5-6 arranged horizontally, so that the end of the optical fiber is aligned with the guide part of the optical fiber transmission mechanism. The vertical movement of the first adjusting roller 5-3 and the second adjusting roller 5-4 can better adapt to the height of the optical fiber position.
[0045] like Figure 5As shown, the fiber optic transmission mechanism 4 includes a second motor 4-1. The drive end of the second motor 4-1 is connected to a drive pulley 4-2. The drive pulley 4-2 is connected to a driven pulley 4-4 via a first transmission belt 4-3. The driven pulley 4-4 is coaxially connected to a first transmission roller 4-5. The first transmission roller 4-5 and the second transmission roller 4-6 are respectively fixed on the two drive ends of a roller gripper 4-7. The roller gripper 4-7 is used to drive the first transmission roller 4-5 and the second transmission roller 4-6 to move. One end of the connecting shaft shared by the driven pulley 4-4 and the first transmission roller 4-5 is connected to one drive end of the roller gripper 4-7. The optical fiber is located between the first conveying roller 4-5 and the second conveying roller 4-6. The first conveying roller 4-5 and the second conveying roller 4-6 clamp the optical fiber. The second motor 4-1 drives the first conveying roller 4-5 to rotate through the synchronous belt pulley. The first conveying roller 4-5 rotates clockwise. One of the drive ends of the roller gripper 4-7 drives the second conveying roller 4-6 to rotate counterclockwise. The rotation speeds of the two rollers can be different. The movement of the first conveying roller 4-5 and the second conveying roller 4-6 rubs against the optical fiber, causing the optical fiber to be conveyed forward. The reason why the first conveying roller 4-5 is driven to rotate by the drive pulley 4-2 through the first transmission belt 4-3 and also driven by the other drive end of the roller gripper 4-7 is that the optical fiber passes through the gap between the first conveying roller 4-5 and the second conveying roller 4-6. The first conveying roller 4-5 and the second conveying roller 4-6 need to be clamped together to transmit power. The first conveying roller 4-5 needs to be able to move up and down and also rotate in order to achieve the friction between the first conveying roller 4-5 and the second conveying roller 4-6 to transmit the optical fiber forward. The other drive end of the roller gripper 4-7 can drive the first conveying roller 4-5 to achieve a small up and down movement of 1-2 mm. The first transmission belt 4-3 can achieve a small up and down movement of the first conveying roller 4-5 with a gap of 1-2 mm. Alternatively, the other drive end of the roller gripper 4-7 can drive the first conveying roller 4-5 to rotate clockwise, and the drive pulley 4-2 can drive the first conveying roller 4-5 to move up and down with a small up and down movement of 1-2 mm through the first transmission belt 4-3. The optical fiber transmission mechanism 4 includes an optical fiber transmission mechanism base 4-8, which is fixed to the upright plate 1 by bolts to fix the optical fiber transmission mechanism 4 on the upright plate 1. The bottom of the second motor 4-1 can be placed on the base plate 10, and the base plate 10 supports the second motor 4-1.
[0046] like Figure 6As shown, the fiber optic cutting mechanism 3 includes a cutting gripper 3-1. The cutting gripper 3-1 has two drive ends, each connected to a cutter. The two cutters are arranged opposite to each other, namely a front cutter 3-2 and a rear cutter 3-3. The cutting gripper 3-1 is used to drive the front cutter 3-2 and the rear cutter 3-3 to move. When the optical fiber is between the front cutter 3-2 and the rear cutter 3-3, the front cutter 3-2 moves towards the rear cutter 3-3, and the rear cutter 3-3 moves towards the front cutter 3-2. The relative movement of the two cutters cuts the optical fiber. The fiber optic cutting mechanism 3 includes a fiber optic cutting mechanism base 3-4. The fiber optic cutting mechanism base 3-4 is fixed to the upright plate 1 by bolts to fix the fiber optic cutting mechanism 3 on the upright plate 1. The fiber optic cutting mechanism 3 is installed on the upright plate 1 near the frame 9.
[0047] like Figure 7 and Figure 8 As shown, the automatic fiber pulling mechanism 2 includes an optical fiber clamping assembly and an optical fiber moving assembly. The optical fiber clamping assembly includes a cam elastic pressure head assembly and a multi-link clamping assembly. The cam elastic pressure head assembly includes a cam rod assembly and an elastic push rod mechanism. The cam rod assembly includes a cam rod 2-1 and a first rotating shaft 2-2. The first rotating shaft 2-2 is connected between two side plates 2-16, and a back plate 2-18 is connected to the bottom of the two side plates. The back plate 2-18 is vertically downward. The first rotating shaft 2-2 passes through one side of the cam rod 2-1 to the other side of the cam rod 2-1. The cam rod 2-1 and the first rotating shaft 2-2 are hinged together, and the cam rod 2-1 can rotate around the first rotating shaft 2-2.
[0048] The elastic push rod mechanism includes a top plate 2-3, a spring 2-4, and a guide mechanism 2-5. Both the top plate 2-3 and the guide mechanism 2-5 are horizontal plates, and the top plate 2-3 and the guide mechanism 2-5 are arranged vertically. The top end of the vertical connecting rod 2-17 is connected to the lower surface of the top plate 2-3, and the lower end of the connecting rod 2-17 passes through the guide mechanism 2-5. After the lower end of the connecting rod 2-17 extends out from the guide mechanism 2-5, the bottom end of the connecting rod 2-17 is connected to the horizontal first connecting rod 2-6.
[0049] The end of the cam rod 2-1 is connected to the upper surface of the top plate 2-3 by bolts or welding. A spring 2-4 is wound around the upper part of the connecting rod 2-17, and is located between the top plate 2-3 and the guide mechanism 2-5. The top end of the spring 2-4 is connected to the bottom surface of the top plate 2-3. The upper part of the connecting rod 2-17 is in clearance fit with the top plate 2-3, allowing the top plate 2-3 to slide up and down along the upper part of the connecting rod 2-17. The connecting rod 2-17 is in clearance fit with the guide mechanism 2-5, allowing the lower part of the connecting rod 2-17 to slide up and down along the guide mechanism 2-5.
[0050] The bottom end of connecting rod 2-17 is connected to the middle of the upper surface of the transverse first connecting rod 2-6. A second connecting rod 2-7 is connected to the upper surface of each side of the first connecting rod 2-6. One end of the second connecting rod 2-7 is hinged to the upper surface of each side of the first connecting rod 2-6, and the other end of the second connecting rod 2-7 is hinged to the top of the third connecting rod 2-8. Each of the two second connecting rods 2-7 is connected to one of the third connecting rods 2-8. Each of the two third connecting rods 2-8 is connected to a second rotating shaft 2-10. The second rotating shaft 2-10 extends from the third connecting rod 2-17... One side of the 8-link passes through to the other side of the third link 2-8. The third link 2-8 is hinged to the second rotating shaft 2-10. The third link 2-8 can rotate around the second rotating shaft 2-10. The lower part of each of the two third links 2-8 is connected to a clamp 2-9. The two clamps 2-9 are located between the two third links 2-8. The end of the clamp 2-9 is connected to the lower part of the inner side of one of the third links 2-8. The top of the clamp 2-9 faces the other third link 2-8. The optical fiber can be clamped between the tops of the two clamps 2-9.
[0051] like Figure 1 , Figure 9 , Figure 10 and Figure 11 As shown, the right side of the storage cabinet 12-1 is fixedly connected to the side of the frame 9. The frame 9 is a square body. The height of the frame 9 is higher than the height of the base plate 10 but lower than the height of the bottom surface of the control panel 12-4. A material groove 2-14 is provided on the upper surface of the frame 9. The material groove 2-14 is in the shape of a groove. The length of the material groove 2-14 is longer than the length of the frame 9. One end of the material groove 2-14 extends to the top of the base plate 10.
[0052] A limit block 2-15 is fixedly installed on the upper surface of the side of the material trough 2-14 located above the bottom plate 10. Figure 8 and Figure 9 The limit block 2-15 is only used to indicate that during the process of the automatic fiber pulling mechanism 2 sliding left and right on the material trough 2-14, the cam rod 2-1 will hit the limit block 2-15.
[0053] A limiting block 2-15 is disposed on the upper surface of the side of the material trough 2-14 located above the base plate 10. The lower part of the side of the material trough 2-14 located above the base plate 10 has a notch, at which a third motor 2-19 is disposed. The third motor 2-19 is mounted on the material trough 2-14, which is a groove-shaped groove. The third motor 2-19 is supported by the bottom surface of the groove. The third motor 2-19 is connected to a driving wheel 2-20, which is connected to a driven wheel via a second transmission belt 2-11. The driven wheel is located at the far end of the material trough 2-14. Figures 9 to 11 The driven wheel is not shown in the diagram.
[0054] As shown in the figure, the mounting block 2-12 is fixedly mounted on the second transmission belt 2-11 by bolts. The third motor 2-19 is controlled to rotate forward or reverse by the control panel 12-4, which drives the mounting block 2-12 to move back and forth with the second transmission belt 2-11. The mounting base 2-13 is connected to the mounting block 2-12. The back plate 2-18 of the fiber optic clamping assembly is fixed on the mounting base 2-13. When the third motor 2-19 rotates, the fiber optic clamping assembly moves back and forth with the mounting block 2-12. When the mounting block 2-12 moves toward the storage cabinet 12-1, the cam rod 2-1 will collide with the limiting block 2-15, and the top of the cam rod 2-1 will be pressed down by the limiting block 2-15.
[0055] The end of cam rod 2-1 is connected to the upper surface of top plate 2-3. When the top of cam rod 2-1 is pressed down by limit block 2-15, the end of cam rod 2-1 rises, causing top plate 2-3 to rise along connecting rod 2-17. The top of spring 2-4 is connected to the bottom surface of top plate 2-3, causing spring 2-4 to be stretched. When top plate 2-3 rises to the top of connecting rod 2-17 and can no longer rise, the top of cam rod 2-1 continues to be pressed down, causing connecting rod 2-17 to move upward along guide mechanism 2-5. The upward movement of link 7 causes the first link 2-6 to move upward. One end of the second link 2-7 is hinged to the upper surfaces of both sides of the first link 2-6. The upward movement of the first link 2-6 causes the second link 2-7 to rotate counterclockwise. The other end of the second link 2-7 is hinged to the top of the third link 2-8, and the third link 2-8 can rotate around the second rotation axis 2-10. The counterclockwise rotation of the second link 2-7 causes the third link 2-8 to rotate counterclockwise around the second rotation axis 2-10. Both third links 2-8 rotate counterclockwise. Rotation causes the two clamps 2-9 to open. Through multi-link transmission, the optical fiber clamped between the tops of the two clamps 2-9 falls between them and into the feed trough 2-14. At this time, the top of the cam rod 2-1 is released, and the end of the cam rod 2-1 presses downward while the spring 2-4 contracts, causing the top plate 2-3 to move downward. The connecting rod 2-17 is in clearance fit with the guide mechanism 2-5. The downward movement of the top plate 2-3 continuously compresses the spring 2-4, causing the connecting rod 2-17 to move along the guide mechanism 2-5. The downward movement of the connecting rod 2-17 causes the first connecting rod 2-6 to move downward. The downward movement of the first connecting rod 2-6 causes the second connecting rod 2-7 to rotate clockwise. The other end of the second connecting rod 2-7 is hinged to the top of the third connecting rod 2-8, and the third connecting rod 2-8 can rotate around the second rotating axis 2-10. The clockwise rotation of the second connecting rod 2-7 causes the third connecting rod 2-8 to rotate clockwise around the second rotating axis 2-10. The clockwise rotation of the two third connecting rods 2-8 causes the tops of the two clamps 2-9 to contact and clamp together.
[0056] In this invention, the third motor 2-19 and the mounting block 2-12 can also be configured as a linear movement mechanism in the form of a lead screw and slider. A lead screw is provided on one side of the frame 9, and the mounting block 2-12 is sleeved on the lead screw. The rotation of the third motor 2-19 can drive the mounting block 2-12 to move on the lead screw.
[0057] In this invention, the optical fiber transmission mechanism 4 is used to transport optical fibers; the optical fiber cutting mechanism 3 is used to cut optical fibers; the automatic fiber pulling mechanism 2 includes an optical fiber clamping assembly and an optical fiber moving assembly, the optical fiber clamping assembly is fixed to the moving end of the optical fiber moving assembly, and the optical fiber moving assembly is used to drive the optical fiber clamping assembly to move the optical fiber to a set position.
[0058] Along the fiber transmission direction, the fiber passes through the fiber transmission mechanism 4, the fiber cutting mechanism 3 and the automatic fiber pulling mechanism 2 in sequence. This is because when the fiber is transmitted, the front end needs to be suspended and dragged, and after being pulled out to a specified length, it will be cut by the fiber cutting mechanism.
[0059] In this way, the fiber end on the fiber storage mechanism 11 first passes around the idler wheel 8-3, and then passes around the second guide wheel 7 and the first guide wheel 6 in sequence for tensioning and guidance. During the process of the first motor 11-3 driving the fiber disk 11-1 to transport the fiber, if the fiber movement speed is too fast or too slow, it may cause the fiber tension to be too large, which may easily lead to breakage. When the fiber tension exceeds the threshold, the deformation of the tension spring 8-6 will also exceed the threshold. Therefore, by reading the reading of the tension sensor 8-5, it is possible to automatically obtain whether the fiber tension exceeds the threshold, thereby adjusting the speed of the first motor 11-3.
[0060] This invention also relates to a method for slitting and cutting optical fibers using the aforementioned optical fiber slitting and cutting device: The optical fiber is wound onto the optical fiber reel 11-1 of the optical fiber storage mechanism 11. The end of the optical fiber on the optical fiber storage mechanism 11 is manually wound around the idler wheel 8-3, the second guide wheel 7, and the first guide wheel 6 in sequence. Then, the end of the optical fiber extends from the first guide wheel 6 towards the optical fiber positioning guide mechanism 5. The end of the optical fiber passes sequentially between the first fixed roller 5-5 and the second fixed roller 5-6, and between the first positioning roller 5-3 and the second positioning roller 5-4. The optical fiber passes through the first fixed roller 5-5, the second fixed roller 5-6, the first positioning roller 5-3, and the first guide wheel 6. The second positioning roller 5-4 defines the horizontal and vertical positions of the optical fiber. The optical fiber then passes between the first conveying roller 4-5 and the second conveying roller 4-6. With the cutter gripper 3-1 not in operation, the end of the optical fiber passes between the front cutter 3-2 and the rear cutter 3-3. Then, the end of the optical fiber extends from the cutter gripper 3-1 to between the two clamps 2-9, which hold the optical fiber. The optical fiber passes sequentially between the front cutter 3-2 and the rear cutter 3-3 and between the two clamps 2-9. The control panel 12-4 controls the operation of the first motor 11-3 and the second motor 4-1. The first motor 11-3 drives the optical fiber. The rotating disc 11-1 conveys the optical fiber. The second motor 4-1 operates, causing the optical fiber to move forward. The first motor 11-3 and the second motor 4-1 drive the end of the optical fiber to extend forward in the feed trough 2-14. The third motor 2-19 operates, driving the mounting block 2-12 to move away from the limiting block 2-15. This causes the automatic fiber pulling mechanism 2 to clamp the end of the optical fiber and move the optical fiber forward synchronously along the feed trough 2-14. When the set length of optical fiber is obtained, the first motor 11-3, the second motor 4-1, and the third motor 2-19 are stopped or stopped by the control panel 12-4. Machine 2-19 stops working according to the preset program. At this time, the cutting gripper 3-1 is controlled to work through the control panel 12-4, or the cutting gripper 3-1 works according to the preset program to cut the optical fiber. After the optical fiber is cut, the third motor 2-19 is controlled to work through the control panel 12-4, or the third motor 2-19 works according to the preset program. The third motor 2-19 drives the mounting block 2-12 to move closer to the limit block 2-15. When the cam rod 2-1 hits the limit block 2-15, the two clamps 2-9 open, and the optical fiber falls into the material trough 2-14. The operator takes out the optical fiber from the material trough 2-14 for use.
