Abstract
Description
[0001] This case is a divisional application of application number 202310160926.6. Technical Field
[0002] This invention relates to the field of laser technology, and more particularly to a laser fiber winding device. Background Technology
[0003] Fiber lasers are lasers that use rare-earth-doped glass fibers as the gain medium. They can be developed based on fiber amplifiers: under the action of pump light, high power density is easily formed within the fiber, causing population inversion of the laser energy levels in the laser gain medium. When a positive feedback loop is appropriately added (forming a resonant cavity), laser oscillation output can be generated. Fiber lasers have a wide range of applications, including laser fiber communication, laser long-distance space communication, industrial shipbuilding, automobile manufacturing, laser engraving, laser marking, laser cutting, printing roller manufacturing, metal and non-metal drilling / cutting / welding (brazing, quenching, cladding, and deep welding), medical devices and equipment, large-scale infrastructure construction, and as a pump source for other lasers, etc.
[0004] The winding of optical fibers in fiber lasers is primarily done manually. The fibers are positioned on the active fiber roller through fiber slots and then manually wound. Since the quality and efficiency of winding depend entirely on the operator's skill, this method is not only inefficient but also inconsistent, resulting in unreliable quality. In typical methods, the fibers often unravel during the fixing process, leading to poor fixation and rework.
[0005] To address this problem, a device capable of coiling optical fibers is proposed. Summary of the Invention

[0063] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with respect to... Figure 1 The orientation is used as a reference.
[0064] While exemplary embodiments of the invention are shown in the accompanying drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention can be understood more clearly and thoroughly, and that the full scope of the invention can be conveyed to those skilled in the art.
[0065] like Figure 1 As shown, this invention provides a laser fiber winding device for winding optical fibers from an active fiber roller 2 onto a fiber optic disk. The laser fiber winding device includes a driving mechanism 1, a cleaning mechanism, a fiber feeding mechanism, and a winding mechanism arranged sequentially along the x-axis, where the x-axis is the direction of fiber transport. Figure 1The optical fiber is fed from left to right. The drive mechanism 1 is used to mount the active optical fiber roller 2, and the rotation axis of the active optical fiber roller 2 is parallel to the y-axis, which is perpendicular to the x-axis. The drive mechanism 1 is a geared motor, and the active optical fiber roller 2 is mounted on the shaft of the geared motor. The geared motor drives the active optical fiber roller 2 to rotate at a constant speed, causing the optical fiber to unwind. Due to the winding pattern of the optical fiber on the active optical fiber roller 2, the optical fiber will move up and down along the y-axis during unwinding. The cleaning mechanism includes a first cleaning wheel group 4 and a second cleaning wheel group 5 arranged sequentially along the x-axis. The optical fiber that comes off the surface of the active optical fiber roller 2 passes through the first cleaning wheel group 4 and the second cleaning wheel group 5 sequentially before being inserted into the fiber feeding mechanism. The rotation axes of both the first cleaning wheel group 4 and the second cleaning wheel group 5 are parallel to the y-axis. The first cleaning wheel group 4 is used to clean the optical fiber, and the second cleaning wheel group 5 is used to wipe the cleaned optical fiber, ensuring that there is no residue of cleaning fluid or dirt on the optical fiber, thus achieving online cleaning and improving the cleanliness of the optical fiber. The fiber feeding mechanism includes multiple fiber feeding platforms arranged sequentially along the x-axis. Preferably, this invention uses two fiber feeding platforms to drive the unwound optical fiber to move along the x-axis. Each fiber feeding platform includes a fiber feeding pulley group 11 and a reciprocating assembly. The fiber feeding pulley group 11 is mounted on the reciprocating assembly, and its axis of rotation is parallel to the z-axis. The fiber feeding pulley group 11 clamps the optical fiber and drives its movement through friction. The reciprocating assembly drives the fiber feeding pulley group 11 to reciprocate along the y-axis, matching the reciprocating movement of the optical fiber along the y-axis during unwinding. This ensures that the center of the fiber feeding pulley group 11 is always coaxial with the optical fiber, thereby maintaining the optical fiber parallel to the x-axis and preventing bending. The x-axis is perpendicular to the y-axis, and both the x-axis and y-axis are perpendicular to the z-axis. The optical fiber exiting the second cleaning wheel group 5 passes sequentially through multiple fiber feeding pulley groups 11. The movement of the optical fiber is driven by these synchronously rotating pulley groups 11, ensuring stable fiber delivery. The winding mechanism is used to effectively wind the optical fiber exiting the fiber feed pulley assembly 11 into the fiber slot on the fiber optic disc, improving the fiber fixation effect and preventing the fiber from unraveling and causing rework. The laser fiber winding device of this invention reduces the impact of human operation on the laser, improves product consistency, and effectively reduces labor intensity and increases work efficiency.
[0066] like Figure 2As shown, the winding mechanism includes a base plate 121, a mounting frame 122, a guide frame 14, and a speed control assembly. The base plate 121 is horizontally positioned, and the mounting frame 122 is vertically mounted on the base plate 121. The fiber optic disc is rotatably mounted on the base plate 121 and can rotate in the horizontal plane. The guide frame 14 slides on the mounting frame 122 and is used to guide the optical fiber into the fiber slot on the fiber optic disc. The guide frame 14 is driven by a servo motor and moves radially along the fiber optic disc. The guide frame 14 has a triangular structure with guide rods at the top and bottom to ensure that the lowermost end of the guide frame 14 is always above the fiber winding point. The optical fiber extends downwards along the left guide rod of the guide frame 14 until it enters the fiber slot. A through hole for the optical fiber is opened on the left guide rod, and the optical fiber slides in the through hole. The optical fiber enters from the top of the left guide rod and exits from the bottom of the left guide rod, guiding the optical fiber into the fiber slot engraved on the fiber optic disc. Since the fiber feeding pulley group 11 moves at a constant speed, the shape of the fiber slot on the fiber disk gradually increases. The speed regulating component can be connected to the fiber disk to drive the fiber disk to rotate, thereby adjusting the rotation speed of the fiber disk so that the linear velocity of the fiber insertion point on the fiber disk is equal to the linear velocity of the source fiber roller surface, and the fiber is inserted into the fiber slot at a constant speed.
[0067] Specifically, such as Figure 3 As shown, the speed regulating assembly includes a driving pulley 15, a driven speed regulating pulley 16, a belt, a tensioner, a first hydraulic cylinder 17, and a speed regulating cam 18. The piston rod of the first hydraulic cylinder 17 abuts against the speed regulating cam 18, and the cam's structure is as follows... Figure 4As shown, the diameter gradually increases. The speed-regulating driven wheel 16 includes multiple pulleys and multiple second hydraulic cylinders. The ends of the cylinder barrels of the multiple second hydraulic cylinders are connected to the same rotating shaft, which is a hollow tube. The rodless chambers of the multiple second hydraulic cylinders are all connected to the rotating shaft. The rodless chamber of the first hydraulic cylinder 17 is connected to the first end of the hydraulic pipe, and the second end of the hydraulic pipe is rotatably connected to the rotating shaft, thereby connecting the rodless chambers of the first hydraulic cylinder 17 and the second hydraulic cylinder in series. The speed-regulating cam 18 is driven by a servo motor, which is controlled by a controller to rotate, thereby driving the speed-regulating cam 18 to rotate. Alternatively, it can be driven by a fiber optic disc drive wheel 15 with a reduction ratio of n:1, where n is the same as the number of turns of the fiber optic cable wound on the fiber optic disc. The rotation of the speed-regulating cam 18 compresses the first hydraulic cylinder 17, and the hydraulic oil is conducted to the inside of the second hydraulic cylinder through the hydraulic pipe, causing the piston rod of the second hydraulic cylinder to extend. The piston rods of the multiple second hydraulic cylinders are evenly arranged radially along the rotating shaft of the speed-regulating driven wheel 16, and the multiple pulleys are rotatably connected to the top ends of the piston rods of the multiple second hydraulic cylinders one by one. The belt is wound around the drive pulley 15 and some of the pulleys, and is supported by these pulleys. The tension pulley's shaft is mounted via a connecting arm and a spring, and the tension pulley abuts against the belt to tension it. The rotation of the speed-regulating cam 18 compresses the first hydraulic cylinder 17, and hydraulic oil is transmitted through hydraulic pipes to the interiors of multiple second hydraulic cylinders, causing the piston rods of the multiple second hydraulic cylinders to extend synchronously. This increases the diameter of the speed-regulating driven pulley 16, increases the reduction ratio between the drive pulley 15 and the speed-regulating driven pulley 16, and reduces the rotational speed of the fiber optic disc, thereby maintaining a constant linear velocity at the fiber insertion point on the fiber optic disc.
[0068] like Figure 4 and Figure 5 As shown, if the fiber optic disc is a 15-turn spiral, with 24 division points evenly distributed in each turn, the first turn of the spiral is denoted as A1-X1, and the second to fifteenth turns are denoted as A2-X2, A3-X3, ..., A15-X15. The speed-regulating cam 18 is divided into 15 regions along its outer circumference, also denoted as A1-X1, A2-X2, A3-X3, ..., A15-X15. Each region on the speed-regulating cam 18 has 24 evenly distributed division points, each corresponding to a division point on the fiber optic disc. The length from each division point to the center of the fiber optic disc is the same as the length from each division point to the center of the speed-regulating cam 18. The fiber optic disc and the speed-regulating cam 18 rotate simultaneously, with a rotation speed ratio equal to the number of spiral turns in the fiber optic disc, i.e., 15:1. The speed-regulating cam 18 achieves stepless speed regulation of the fiber optic disc by adjusting the length of its centerline.
[0069] like Figure 2As shown, the winding mechanism also includes a mounting post 123, a sleeve, and multiple anti-detachment rollers 13. The mounting post 123 is vertically fixed on the mounting frame 122, with its first end close to the fiber optic disc. The sleeve is fitted onto the first end of the mounting post 123, and a spring is vertically arranged between the sleeve and the first end of the mounting post 123. The spring is compressed between the sleeve and the first end of the mounting post 123, with its upper end abutting against the first end of the mounting post 123 and its lower end abutting against the inner wall of the sleeve, thus ensuring that the spring always provides a downward thrust to the sleeve. The first end of the rotating shaft of the anti-detachment roller 13 is connected to the sleeve, and the rotating shafts of the multiple anti-detachment rollers 13 are evenly arranged radially along the sleeve. The anti-detachment rollers 13 are rotatably fitted onto the rotating shafts. The outer surface of the anti-detachment roller 13 abuts against the side of the fiber optic disc with the fiber slot. Through elasticity, the anti-detachment roller 13 is pressed against the upper surface of the fiber optic disc, preventing the sleeve from contacting the fiber optic disc. After the optical fiber enters the fiber groove engraved on the optical fiber disk, the anti-detachment roller 13 rolls over the optical fiber due to the rotation of the optical fiber disk, making the optical fiber fit firmly against the fiber groove and preventing it from coming out. This further ensures that the optical fiber exiting the fiber feed pulley assembly 11 is effectively coiled and placed into the fiber groove on the optical fiber disk, improving the fixation effect of the optical fiber. The roller is covered with polyurethane material to prevent scratching the optical fiber.
[0070] like Figure 6 and Figure 7 As shown, the first cleaning roller assembly 4 includes a cleaning frame 3, a fixed roller 27, and a movable roller 25. The fixed roller 27 is mounted on the cleaning frame 3 and has a hollow cylindrical structure. It is filled with anhydrous alcohol, and multiple outlet holes are provided on its sidewalls, allowing the anhydrous alcohol to flow through these holes to the outer surface of the roller. The movable roller 25 is rotatably mounted on the cleaning frame 3, with the central axes of both the fixed roller 27 and the movable roller 25 parallel to the y-axis. The outer surfaces of both the fixed roller 27 and the movable roller 25 are covered with a porous elastic material layer 28, preferably sponge. The outer surfaces of the fixed roller 27 and the movable roller 25 abut against each other to hold the optical fiber. The sponge on the fixed roller 27 absorbs the anhydrous alcohol, and the sponge on the movable roller 25 draws anhydrous alcohol from the sponge on the fixed roller 27. After the optical fiber passes through the fixed roller 27 and the movable roller 25, the alcohol is applied to the surface of the optical fiber to dissolve contaminants. The second cleaning wheel set 5 includes two rollers rotatably mounted on the cleaning frame 3. The rotation axes of the two rollers are parallel to the y-axis direction, and their outer surfaces are covered with dust-free paper to hold optical fibers and remove contaminants from the surface of the optical fibers.
[0071] Further, see Figure 7The first cleaning wheel assembly 4 also includes a cleaning drive assembly and a reciprocating piston 22. The reciprocating piston 22 is disposed within the fixed roller 27, dividing the fixed roller 27 into a first chamber and a second chamber. The cleaning drive assembly is disposed on the cleaning frame 3, and the cleaning drive assembly can drive the reciprocating piston 22 to reciprocate in the y-axis direction. When the reciprocating piston 22 moves to the left, it compresses the first chamber, and when the reciprocating piston 22 moves to the right, it compresses the second chamber. Multiple liquid outlets are designated as a first liquid outlet 23 and a second liquid outlet. The first liquid outlet 23 is located near the first end of the fixed roller 27, and the second liquid outlet is located near the second end of the fixed roller 27. The first liquid outlet 23 connects to the first chamber, and the second liquid outlet connects to the second chamber. The side wall of the fixed roller 27 is also provided with a first inlet hole and a second inlet hole 24. The first inlet hole is close to the first end of the fixed roller 27, and the second inlet hole 24 is close to the second end of the fixed roller 27. The first inlet hole connects to the first chamber, which is connected to a container for storing anhydrous alcohol through the first inlet hole. The second inlet hole 24 connects to the second chamber, which is connected to a container for storing anhydrous alcohol through the second inlet hole 24. One-way valves 26 are provided in the first outlet hole 23, the second outlet hole, the first outlet hole 23, and the second outlet hole. When the reciprocating piston 22 moves to the left, the first chamber is compressed, the first inlet hole is closed by the one-way valve 26, and the first outlet hole 23 is opened, allowing anhydrous alcohol to enter the outer surface of the fixed roller 27 through the first outlet hole 23. Simultaneously, the space in the first chamber of the fixed roller 27 increases, the internal pressure decreases, the second outlet hole is closed by the one-way valve 26, and the second inlet hole 24 is opened, allowing anhydrous alcohol to enter the second chamber through the second inlet hole 24. The outer surface of the movable roller 25 is provided with multiple evenly distributed small holes, connecting its surface and inner cavity. This also allows alcohol absorbed by the sponge on the movable roller 25 to be squeezed into the inner cavity for storage. Anhydrous alcohol is continuously applied to the optical fiber via the fixed roller 27 and the movable roller 25 to dissolve contaminants on the fiber surface.
[0072] like Figure 6 and Figure 7 As shown, the cleaning drive assembly includes a first geared motor 19, a connecting rod, a bracket 21, and a swing linkage 20. The connecting rod is slidably sleeved in the fixed roller 27 along the y-axis, and the reciprocating piston 22 is sleeved on the connecting rod. Both ends of the connecting rod extend from both ends of the fixed roller 27, and there is a rotational seal between the connecting rod and the fixed roller 27. The part of the connecting rod extending out of the fixed roller 27 is connected to the bracket 21. The first geared motor 19 is mounted on the cleaning frame 3. The rotating shaft of the first geared motor 19 is connected to the bracket 21 through the swing linkage 20. The first geared motor 19 rotates, and the swing linkage 20 and the bracket 21 convert the rotational motion into reciprocating motion, which is then transmitted to the reciprocating piston 22 through the connecting rod, thereby realizing the reciprocating motion of the reciprocating piston 22 within the fixed roller 27.
[0073] See Figure 1The reciprocating assembly includes a reciprocating lead screw 8, a lead screw wedge 9, a linear guide rail 7, and a sliding plate 6. The reciprocating lead screw 8 is rotatably arranged along the y-axis. The drive mechanism 1 is connected to the reciprocating lead screw 8 to drive its rotation. The lead screw wedge 9 is sleeved on the reciprocating lead screw 8. The linear guide rail 7 is arranged along the y-axis. The sliding plate 6 is slidably connected to the linear guide rail 7 and is also connected to the lead screw wedge 9. The fiber feed pulley assembly 11 is arranged on the sliding plate 6. The speed ratio between the active fiber roller 2 and the reciprocating lead screw 8 is 5:1, and the pitch of the thread on the reciprocating lead screw 8 is 5 times the fiber diameter. Specifically, multiple reciprocating lead screws 8 are connected to each other and to the drive mechanism 1 via synchronous pulleys 10. The speed ratio between the active fiber roller 2 and the reciprocating lead screw 8 is 5:1, and the pitch of the reciprocating lead screw 8 is 5 times the fiber diameter. By setting the pitch and reduction ratio, the center of the fiber feed pulley assembly 11 can be made coaxial with the fiber. When the fiber feed pulley assembly 11 moves to its limit position, the slider inside the lead screw wedge 9 will be reversed via the reciprocating lead screw 8, causing the fiber feed pulley assembly 11 to move in the opposite direction to synchronously match the movement of the optical fiber in the y-axis direction during unwinding. The fiber feed pulley assembly 11 includes a second geared motor, a first pulley, and a second pulley. The second geared motor is mounted on the slide plate 6. The first and second pulleys are both rotatably mounted on the slide plate 6 via shafts. The shafts of the first and second pulleys are parallel to the z-axis direction. The outer surfaces of the first and second pulleys abut against each other to clamp the optical fiber, ensuring sufficient friction to drive the optical fiber and preventing slippage. The shafts of the first and second pulleys are both connected to the shaft of the second geared motor, which drives the first and second pulleys to rotate. The first and second pulleys rotate at the same speed and in opposite directions, and multiple fiber feed pulley assemblies 11 rotate synchronously. The linear velocity of the first pulley surface is equal to the linear velocity of the active optical fiber roller 2 surface, thus completing the uniform speed transport of the optical fiber.
[0074] During operation, the optical fiber, driven by the drive mechanism 1, is released through the active fiber roller 2, clamped by multiple fiber feeding pulley sets 11, and fed to the right. It then enters the fiber slot engraved on the fiber optic tray via the guide frame 14, completing the fiber feeding action. The rotation of the reciprocating screw 8 and the reversing action of the screw wedge block 9 drive the fiber feeding pulley sets 11, ensuring that the center of the fiber feeding pulley sets 11 remains coaxial with the optical fiber, thus ensuring stable fiber feeding. The speed-regulating cam 18 continuously adjusts the speed of the fiber optic tray, ensuring that the linear velocity of the fiber insertion point around the rotation center remains constant. The rolling and pressing action of the fiber anti-detachment roller 13 prevents the optical fiber from detaching from the fiber slot again.
