Description

Technical Field

[0001] This utility model relates to the field of laser beam combiner technology, and in particular to a laser beam combiner twisting and pulling tapering device. Background Technology

[0002] Fiber lasers possess advantages such as high conversion efficiency, small size, high flexibility, good heat dissipation, high output beam quality, high stability, and suitability for high-power applications, making them promising candidates for use in manufacturing, medicine, and military fields. Fiber combiners are one of the key components in fiber laser development. As passive devices, they enable directional power transmission and play a crucial role in high-power all-fiber lasers. Because they are made using optical fibers, they can be connected to other devices through fusion splicing, forming the all-fiber laser structure that is currently receiving significant research attention.

[0003] In the production process of fiber optic combiners, the fused tapering process is crucial, directly determining the product quality. Existing tapering and knotting methods typically involve manual fiber arrangement followed by manual cutting of the taper using a cleaver. This method demands a high level of employee skill and is inefficient, knotting only one side at a time, requiring manual straightening of the fiber before knotting. The inconsistent tension applied to each fiber during manual straightening poses a risk of high temperatures and abnormalities in the knotting area. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a laser beam combiner twisting and tapering device, which improves production efficiency.

[0005] The technical solution of this utility model is as follows: a laser beam combiner twisting and tapering device, including a limiting platform, on which a clamping module, a left rotation module, a right rotation module, and a pendant module are sequentially arranged. A twisting area is provided between the left rotation module and the right rotation module. A melting mechanism and a cutting module are respectively arranged on both sides of the twisting area. The left rotation module and the right rotation module are arranged facing each other. Both the left rotation module and the right rotation module have a rotation drive component and a disk connected to the output end of the rotation drive component. The disk is provided with a plurality of through holes for optical fibers to pass through. The through holes on the two sets of disks are arranged correspondingly. After the clamping module clamps one end of the optical fiber, the optical fiber passes through the left rotation module and the right rotation module in sequence and is then held by the pendant module. The left rotation module and the right rotation module drive the optical fiber to rotate in opposite directions. The melting mechanism heats and melts a plurality of optical fibers into a tapered bundle, which is then cut by the cutting module.

[0006] As described above, the clamping module holds the head end of the optical fiber, while the left and right rotation modules drive the optical fibers on the disk to rotate in opposite directions. A twisted area is formed between the two sets of disks. The disks have several through-holes for the optical fibers to pass through, ensuring that the fibers remain parallel after insertion and preventing interference or twisting. The fusion splicing mechanism heats and melts the twisted optical fibers, and the pendant module holds the tail end of the optical fiber to facilitate tapering during melting. This invention uses a double-sided honeycomb disk for fiber arrangement, resulting in fast, efficient, and consistent arrangement. The simultaneous automatic rotation and knotting of the optical fibers on both sides by the left and right rotation modules improves production efficiency.

[0007] The clamping module includes a mounting base, a cable tray mounted on the mounting base, and a plurality of first clamping members wound around the cable tray. Each first clamping member includes a fixing block, a clamping block, and a spring. The mounting base has a clamping groove, and the fixing block has a fastener. One end of the spring is sleeved on the fastener, and the other end is connected to the clamping block. The clamping block is rotatably connected to the fixing block via a rotating pin, and the bottom of the clamping block contacts the bottom wall of the clamping groove. Therefore, the cable tray clamps and limits the movement of several optical fibers using the plurality of first clamping members. The clamping groove is used to rotatably connect the clamping block to the fixing block, and the spring is used to drive the clamping block to elastically clamp the optical fibers.

[0008] The melting mechanism includes a furnace drive module and a furnace disposed at the output end of the furnace drive module. The moving direction of the furnace drive module is perpendicular to the axis of the optical fiber, and a melting tank is provided on the furnace. Therefore, the melting mechanism uses the furnace drive module to move the furnace closer to the twisting area, thereby tapering the twisted optical fiber.

[0009] The pendant module includes a fixing plate, a plurality of pendant seats disposed on the fixing plate, and a second clamping member hanging on the pendant seats, the second clamping member corresponding to each optical fiber. Thus, the pendant module uses the weights to maintain the tension of individual optical fibers, thereby straightening the optical fibers.

[0010] The rotary drive assembly includes a drive base, a rotary motor mounted on the drive base, a first gear connected to the output end of the rotary motor, and a second gear meshing with the first gear. The disk is coaxially connected to the output shaft of the second gear. Therefore, the rotary motor drives the first gear to rotate, the first gear meshes with the second gear, and the second gear drives the optical fiber on the disk to rotate.

[0011] The disk is connected to the output shaft of the second gear via a connecting sleeve, and the connecting sleeve is provided with a communicating groove corresponding to the through hole.

[0012] The cutting module includes a cutting blade moving drive and a cutting blade connected to the output end of the cutting blade drive, with the blade tip facing the twisted area. Therefore, the cutting blade moving drive moves the cutting blade towards the twisted area to cut the fiber cone bundle. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6 As shown, this utility model is a laser beam combiner twisting and tapering device, including a limiting platform 1. A clamping module 2, a left rotation module 3, a right rotation module 4, and a pendant module 5 are sequentially arranged on the limiting platform 1. A twisting area is provided between the left rotation module 3 and the right rotation module 4. A melting mechanism 6 and a cutting blade module are respectively arranged on both sides of the twisting area. The left rotation module 3 and the right rotation module 4 are arranged facing each other. Both the left rotation module 3 and the right rotation module 4 have rotation drive components and are connected to the rotating... The drive assembly output has a disk 41 with several through holes 411 for optical fibers to pass through. Two sets of through holes 411 on the disks 41 are correspondingly arranged. After the clamping module 2 clamps one end of the optical fiber, the fiber passes sequentially through the left rotation module 3 and the right rotation module 4, and is then held by the pendant module 5. The left rotation module 3 and the right rotation module 4 rotate the optical fiber in opposite directions. The melting mechanism 6 heats and melts several optical fibers into a tapered bundle, which is then cut by the cutting blade module. In this embodiment, the optical fiber is denoted by 100.

[0021] The clamping module 2 includes a mounting base 21, a cable tray 22 disposed on the mounting base 21, and a plurality of first clamping members 23 wound around the cable tray 22. Each first clamping member 23 includes a fixing block 231, a clamping block 232, and a spring 233. The fixing block 231 is provided with a limiting part, and a clamping groove 234 adapted to the clamping block 232 is provided above the limiting part. The fixing block 231 is provided with a fastener 235. One end of the spring 233 is sleeved on the fastener 235, and the other end is connected to the clamping block 232. The clamping block 232 is rotatably connected to the fixing block 231 by a rotating pin, and the bottom of the clamping block 232 contacts the surface wall of the limiting part of the fixing block 231. In this embodiment, the bottom of the clamping block 232 is provided with a rubber pad 237 to avoid damage to the optical fiber during clamping. The cable tray 22 has a polyhedral structure, and the outer surface of the cable tray 22 is evenly distributed with mounting surfaces 221. The first clamping member 23 is disposed on the mounting surface 221. The inner side of the movable end of the clamping block 232 is provided with an inclined surface for gripping and swinging.

[0022] The melting mechanism 6 includes a furnace drive module 61 and a furnace 62 disposed on the output end of the furnace drive module 61. The moving direction of the furnace drive module 61 is perpendicular to the axis of the optical fiber, and the furnace 62 is provided with a melting tank. In this embodiment, the furnace 62 is a graphite heat source furnace, and the melting tank corresponds to the optical fiber.

[0023] The pendant module 5 includes a fixing plate 51, a plurality of pendant seats 52 disposed on the fixing plate 51, and a second clamping member 53 suspended on the pendant seats 52. The second clamping member 53 corresponds one-to-one with the optical fiber. In this embodiment, the optical fiber is wound from the surface of the pendant seat 52 to the second clamping member 53 for clamping. Since the weight of the second clamping member 53 itself is equivalent to a weight, the corresponding optical fiber is under tension after being clamped, so that the optical fiber has a certain tension, allowing multiple optical fibers in the knotted area to be arranged in parallel, then knotted, and then placed in a graphite furnace for melting.

[0024] The rotary drive assembly includes a drive base 40, a rotary motor 42 mounted on the drive base 40, a first gear connected to the output end of the rotary motor 42, and a second gear 43 meshing with the first gear. The disk 41 is coaxially connected to the output shaft of the second gear 43. The disk 41 is connected to the output shaft of the second gear 43 via a connecting sleeve 44, which has a communicating groove 441 corresponding to the through hole 411. In this embodiment, the first gear is disposed within the drive base 40, and the diameter of the first gear is smaller than the diameter of the second gear 43. The connecting sleeve 44 has an opening communicating with the communicating groove 441, and the second gear 43 has an opening groove communicating with the communicating groove 441.

[0025] The cutting blade module includes a cutting blade moving drive and a cutting blade 7 connected to the output end of the cutting blade drive. The tip of the cutting blade 7 is positioned facing the knotting area. In this embodiment, the moving direction of the cutting blade moving drive is opposite to the moving direction of the furnace drive module 61. After the optical fiber is knotted, the furnace moves back and forth controlled by the cutting blade moving drive, allowing the knotted optical fiber to enter the furnace for melting and tapering.

[0026] The workflow of this utility model is as follows: Multiple optical fibers are stripped, a certain length is stripped at the window, and the fibers are wiped clean until the stripping preparation is complete. The optical fibers 100 are respectively threaded through the disks 41 of the rotating module 3 and the right rotating module 4. The threading holes 411 on both disks 41 must correspond to ensure that the optical fibers 100 remain parallel after threading. The stripping window area is located between the two disks 41. The left side of the optical fiber is fixed to the clamping module 2. After threading, the left ends of the multiple optical fibers 100 are fixed using the first clamping member 23, while the right end of each optical fiber 100 is clamped by the second clamping member 53, ensuring that each optical fiber has a certain tension. The two sets of disks 41... Several optical fibers 100 in the twisted region remain parallel, without interfering with or twisting each other. Two sets of rotating motors 42 in the left rotating module 3 and the right rotating module 4 rotate the fiber disks on both sides in opposite directions, for example, the left disk rotates at -180° and the right disk rotates at +180°. A twisted region is formed between the two sets of disks 41. After twisting is complete, the furnace 62 is moved forward, heating and melting the twisted region in the graphite furnace 62. After a period of time, the knotted area of ​​multiple optical fibers melts into a cone bundle. Subsequently, a cleaver is controlled to cut the cone bundle from top to bottom, obtaining 2 half-cones.

[0027] The advantages of this utility model are: 1. The fiber arrangement is fast, efficient and consistent through the double-sided honeycomb disk arrangement.

[0028] 2. The optical fiber is automatically rotated and knotted by two sets of rotary motors, and the tension of each single optical fiber on both sides is uniform, resulting in stable and reliable quality in the knotted area.

[0029] 3. Double-sided knotting - 2 pieces of cones are pulled at a time, doubling efficiency and production capacity compared to single-sided knotting.

[0030] 4. Automatic cutting - smaller cutting angle (<3℃), higher yield of finished products in one cut (≥80%).

[0031] Finally, it should be emphasized that the above description is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
