Description

Technical Field

[0001] The present application relates to the technical field of lasers, and in particular to an adjustable optical fiber winding reel. Background Art

[0002] Before laser products are produced, quality inspected or shipped, their optical fibers need to be coiled and fixed to facilitate turnover, inspection or packaging.

[0003] Traditional fiber optic winding is done manually. After winding N circles, the end of the wire is passed through the circle to keep it relatively fixed in a ring. However, due to the different sizes and strengths of human hands, it is easy to break the fiber and the circles are also of different sizes. Or winding is done by using a jig, such as the winding drum used for daily needlework. The diameter of the jig is fixed and can only be used for a single laser fiber with direct requirements, so the scope of application is small. Summary of the invention

[0004] In order to expand the scope of application, the present application provides an adjustable optical fiber winding reel.

[0005] The adjustable optical fiber winding reel provided in this application adopts the following technical solution: The adjustable optical fiber winding reel comprises a base, the base is provided with a plurality of radially arranged sliding grooves, a winding block is slidably connected in the sliding grooves, a control disk is rotatably connected in the base, a spiral groove is provided on the upper surface of the control disk, and a clamping groove connected to the spiral groove thread is provided at the lower end of the winding block.

[0006] By adopting the above technical solution, the operator rotates the control disk, and the control disk drives all the winding blocks to slide along the sliding groove through the spiral groove. All the winding blocks move synchronously, and the position of the winding block and the distance between the winding block and the center of the base can be changed. When the optical fiber is wound, the optical fiber is wound along the outside of all the winding blocks. The operator can change the position of the winding block by rotating the control disk, thereby changing the size of the optical fiber winding, thereby increasing the scope of application.

[0007] Preferably, the winding block comprises a winding surface facing the edge of the base, and an outwardly protruding support platform is provided below the winding surface, and the length of the support platform protruding from the winding surface is greater than the diameter of the optical fiber.

[0008] By adopting the above technical solution, when the optical fiber is wound in a loop, the optical fiber is wound on the top of the support table and contacts the winding surface, so that after the optical fiber is wound into a loop, there is a gap between the loop formed by the optical fiber and the base, which is convenient for the operator to remove the optical fiber loop from the base.

[0009] Preferably, a baffle is vertically slidably connected to the side of the support platform.

[0010] By adopting the above technical solution, the baffle can limit the position of the optical fiber. When the optical fiber is wound, if a small force is used, the inner wall of the optical fiber coil contacts the winding block, and the baffle slides upward to limit the outer wall of the optical fiber coil to prevent the optical fiber from loosening and falling off; if a large force is used, the inner wall of the optical fiber coil contacts the winding block, and the baffle slides downward to limit the outer wall of the optical fiber coil to prevent the optical fiber from being damaged due to excessive force. In this way, the optical fiber coil is formed, which can prevent the optical fiber from loosening and falling off, and prevent the optical fiber from being damaged due to excessive force.

[0011] Preferably, a transmission rack is provided below the side of the baffle facing the support platform, a transmission gear meshing with the transmission rack is rotatably connected in the support platform, a control rod is vertically rotatably connected in the winding block, a transmission rod located below the control rod and with an axis parallel to the axis of the transmission gear is rotatably connected in the winding block, the lower end of the control rod is connected to the transmission rod through a bevel gear pair, a control gear meshing with the transmission gear is coaxially fixed on the transmission rod, the winding surface is horizontally slidably connected to a plurality of control blocks along the height direction, the control blocks are all located above the support platform, a control rack is provided on the control block and extends into the winding block, and a plurality of connecting gears corresponding to the control rack are provided on the control rod along the height direction.

[0012] By adopting the above technical solution, before the optical fiber is wound, the baffle is in the initial state, and the upper end of the baffle is flush with the upper end of the support platform, which is convenient for the optical fiber to be wound. When the optical fiber is wound, the optical fiber is wound on the winding surface and contacts the control block. As the number of turns increases, the pressure between the optical fiber and the winding surface increases, exerting an extrusion force on the control block, and the control block drives the control rack to move in the direction of the control rod. The control rack contacts the connecting gear and drives the control rod to rotate through the connecting gear. The control rod drives the transmission rod to rotate through the bevel gear pair, and the transmission rod drives the transmission gear to rotate through the control gear. The transmission gear drives the baffle to slide upward through the transmission rack. As the optical fiber gradually winds, the baffle gradually moves up by itself to block the outside of the optical fiber coil to prevent the optical fiber from loosening and falling off, which is convenient to use.

[0013] Preferably, the diameter of the control gear is greater than the diameter of the transmission gear.

[0014] By adopting the above technical solution, the diameter of the control gear is larger, and the transmission ratio is increased, thereby ensuring the shielding effect of the baffle.

[0015] Preferably, a side of the baffle facing the support platform is provided with an elastic protective layer located above the transmission rack.

[0016] By adopting the above technical solution, the protective layer contacts the optical fiber, thereby protecting the optical fiber.

[0017] Preferably, a surface of the baffle away from the support platform is set as an inclined surface, and the thickness of the lower end of the baffle is the largest, and the thickness of the upper end of the baffle is the smallest.

[0018] By adopting the above technical solution, when the operator winds the optical fiber, if the optical fiber is wound on the outer surface of the baffle, since the outer surface of the baffle is an arc or an inclined surface, the optical fiber will slide upward along the outer surface of the baffle and be wound on the winding surface, thereby ensuring the winding effect of the optical fiber.

[0019] Preferably, an adjustment hole is provided on the base, an adjustment rod is rotatably connected in the adjustment hole, an adjustment gear is coaxially provided on the adjustment rod, and an adjustment tooth groove meshing with the adjustment gear is provided on a side of the control disk away from the spiral groove.

[0020] By adopting the above technical solution, the operator rotates the adjusting rod, and the adjusting rod drives the control disk to rotate through the adjusting gear, thereby adjusting the position of the winding block, which is easy to operate.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: Through the settings of the control panel, the operator can adjust the positions of all winding blocks synchronously, thereby changing the size of the optical fiber winding and expanding the scope of application; By setting the support platform and the baffle, when the operator is winding the optical fiber, the baffle can move up to cover the outer wall of the optical fiber loop to prevent the optical fiber from loosening and falling off.

[0024] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0025] Example

[0026] The present application embodiment discloses an adjustable optical fiber winding reel, referring to Figure 1 to Figure 2 , including a base 1, on which a plurality of winding blocks 2 are slidably connected, and the optical fiber is wound around the outer side of the winding block 2 to form an optical fiber loop.

[0027] Reference Figure 1 to Figure 2 The base 1 is provided with a plurality of radially arranged sliding grooves 11, which are evenly distributed on the base 1 in the circumferential direction. The winding block 2 is slidably connected in the sliding grooves 11, and the winding block 2 can slide along the sliding grooves 11, thereby changing the position of the winding block 2 and thus changing the size of the optical fiber loop. The axes of all the sliding grooves 11 pass through the center point of the base 1. The corners of the base 1 and the winding block 2 are both chamfered to protect the optical fiber.

[0028] Reference Figures 1 to 3 The base 1 is rotatably connected with a control disk 3, the upper surface of which is provided with a spiral groove 31, and the lower end of the winding block 2 is provided with a slot 21 threadedly connected with the spiral groove 31. The bottom of the base 1 is provided with an adjustment hole located below the control disk 3, and an adjustment rod 7 is rotatably connected in the adjustment hole, an adjustment gear 71 is coaxially fixed on the adjustment rod 7, and an adjustment tooth groove 32 meshing with the adjustment gear 71 is provided on the lower surface of the control disk 3. The operator rotates the adjustment rod 7 to drive the control disk 3 to rotate, thereby synchronously driving all the winding blocks 2 to slide linearly along the sliding groove 11, thereby changing the size of the optical fiber loop.

[0029] Reference Figures 1 to 3 The side of the winding block 2 that is away from the center point of the base 1, that is, toward the edge of the base 1, is a winding surface 22, which is used to contact the optical fiber. A support platform 4 that protrudes outward is fixed below the winding surface 22, and the length of the support platform 4 protruding from the winding surface 22 is greater than the diameter of the optical fiber. When the optical fiber is wound, the optical fiber coil is located above the support platform 4 and contacts the winding surface 22. The lower part of the optical fiber coil is located on the support platform 4 and there is a gap between it and the upper surface of the base 1, so that it is convenient for the operator to remove the optical fiber coil from the base 1.

[0030] Reference Figures 1 to 3 The side of the support platform 4 away from the center of the base 1 is vertically slidably connected with a baffle 5, and the side of the baffle 5 away from the support platform 4 is set as an inclined surface, and the thickness of the lower end of the baffle 5 is the largest, and the thickness of the upper end of the baffle 5 is the smallest. When the operator winds the optical fiber, if the optical fiber is not less than the side of the baffle 5, since the side of the baffle 5 is an inclined surface, when winding, the optical fiber will slide upward along the baffle 5 and fall on the winding surface 22, thereby ensuring the winding effect of the optical fiber.

[0031] Reference Figures 1 to 4 The support platform 4 is hollow, and an elastic protective layer is provided above one side of the baffle 5 facing the support platform 4. When the baffle 5 moves up to shield the optical fiber, the protective layer contacts the outer side of the optical fiber loop to protect the optical fiber.

[0032] Reference Figures 1 to 4 A transmission rack 51 is provided below the protective layer on the side of the baffle plate 5 facing the support platform 4, and a transmission gear 61 meshing with the transmission rack 51 is rotatably connected in the support platform 4. The transmission gear 61 rotates to drive the baffle plate 5 to slide up and down. The protective layer can be a soft rubber material, and the protective layer contacts the optical fiber to protect the optical fiber.

[0033] Reference Figures 1 to 4 A transmission rod 63 is rotatably connected in the winding block 2, and a control gear 64 meshing with the transmission gear 61 is coaxially fixed on the transmission rod 63, and the diameter of the control gear 64 is larger than the diameter of the transmission gear 61. When the transmission rod 63 rotates, the control gear 64 rotates more circles, thereby increasing the movement stroke of the baffle 5.

[0034] Reference Figures 1 to 4 , a control rod 62 located above the transmission rod 63 is vertically rotatably connected in the winding block 2, and the lower end of the control rod 62 is connected to the transmission rod 63 through a bevel gear pair and drives the transmission rod 63 to rotate. A plurality of connecting gears 67 are coaxially fixed above the control rod 62 along its own height direction. A plurality of control blocks 65 protruding from the winding surface 22 are horizontally slidably connected to the winding surface 22, and the plurality of control blocks 65 are arranged along the vertical direction of the winding surface 22, and the control blocks 65 correspond to the connecting gears 67 one by one. A control rack 66 matching the connecting gear 67 is fixed to one end of the control block 65 facing the connecting gear 67.

[0035] Reference Figures 1 to 4 When the operator winds the optical fiber, the optical fiber is wound on the winding surface 22 and contacts the control block 65. The optical fiber applies pressure to the control block 65, sliding the control block 65 toward the control rod 62. The control rack 66 drives the control rod 62 to rotate through the connecting gear 67. The control rod 62 drives the transmission rod 63 to rotate through the bevel gear pair. The transmission rod 63 drives the baffle 5 to move up through the transmission gear 61 to block the outside of the optical fiber loop. When the operator is winding the optical fiber, the baffle 5 automatically rises to block the outside of the optical fiber loop to prevent the optical fiber loop from loosening and falling off, which is convenient to use. The corners of the control block 65 are all chamfered to protect the optical fiber.

[0036] Reference Figures 1 to 4, the control block 65 is T-shaped, the end of the control block 65 with a larger diameter is located inside the winding block 2, and the control rack 66 is connected to the end of the control block 65 with a larger diameter. The part of the control block 65 with a smaller diameter protrudes from the winding surface 22, and the length of the control block 65 extending from the winding surface 22 is less than the length of the support platform 4. When the part of the control block 65 with a smaller diameter completely extends out of the winding surface 22, the control rack 66 is disengaged from the connecting gear 67. When the optical fiber is wound, it is wound from bottom to top in sequence, and the control block 65 located at the bottom first contacts the optical fiber and is pressed into the winding block 2. The control blocks 65 gradually slide from bottom to top in sequence, and one of the control blocks 65 slides toward the control rod 62, and the control rack 66 drives the control rod 62 to rotate through the link rack. When the control rod 62 rotates, since the control rack 66 of the upper control block 65 does not contact the connecting gear 67, the upper control block 65 will not be driven by the control rod 62 to shrink inward, so as not to affect the winding of the optical fiber.

[0037] Reference Figures 1 to 4 A control spring is provided between the control block 65 and the winding block 2. When the control spring is in a natural state, the smaller diameter portion of the control block 65 completely extends out of the winding surface 22 to ensure the initial state of the control block 65. The elastic force of the control spring is small so as not to affect the winding of the optical fiber. After the winding is completed, the optical fiber coil is removed from the base 1, and the baffle 5 is pressed downward, and the baffle 5 and the control block 65 are reset.

[0038] The implementation principle of the adjustable optical fiber winding reel of the embodiment of the present application is as follows: the operator rotates the adjustment lever 7 according to the demand to adjust the position of the winding block 2, thereby adjusting the size of the optical fiber winding. After the adjustment is completed, the operator winds the optical fiber on the winding block 2. After the winding is completed, the operator removes the optical fiber from the base 1 and presses the baffle 5 to reset it.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
