Description

Technical Field

[0001] This utility model relates to the field of optical fiber processing technology, and in particular to an automatic fiber stripping device. Background Technology

[0002] As optical fiber communication networks continue to develop towards higher speeds and higher densities, increasingly stringent requirements are being placed on the efficiency and accuracy of operations such as optical fiber splicing and termination. Fiber stripping is a crucial and easily damaged basic process in these operations.

[0003] In the industry's common fiber stripping solutions, manual mechanical stripping is often used. Operators use simple mechanical wire strippers, relying on feel and experience to scrape the fiber. However, due to the lack of precise force and depth control during the stripping process, manual operation or mechanical stripping with mismatched parameters can easily scratch or abrade the fragile quartz fiber core, leading to fiber strength degradation and increased transmission loss, thereby reducing product yield. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic fiber stripping device, which solves the problem that manual mechanical fiber stripping methods in the prior art are prone to scratching or abrading the fragile quartz fiber core, thereby reducing the yield of optical fiber products.

The fiber stripping unit includes a mounting base, a blade, and a drive assembly disposed between the mounting base and the blade. The drive assembly is used to drive the blade to move toward or away from the base. The moving unit is located between the base plate and the mounting base and is used to drive the fiber stripping unit to move along the fiber axis to strip the cladding of the fiber.

[0006] Preferably, the pressing unit includes: The first transmission rod is located at the top of the support frame; The pressing plate is located at the telescopic end of the first transmission rod and corresponds one-to-one with the base.

[0008] Preferably, the driving component includes: The second transmission rod is located on the side of the mounting base; The mounting plate is located at the telescopic end of the second transmission rod, and the blade is located at the bottom of the mounting plate.

[0009] Preferably, the bottom of the mounting plate is also provided with a heating unit for heating the blade.

[0010] Preferably, the moving unit includes: A fixing plate is installed on the base plate; The support seat is slidably mounted on the fixed plate, and the mounting seat is fixedly mounted on the support seat; A lead screw is mounted on a base plate, and a bearing seat is connected to the lead screw via a transmission. A transmission device is located on the side of the base plate, and the output shaft of the transmission device is connected to the end of the lead screw.

[0011] Preferably, the fixed plate is provided with a slide rail, and the bottom of the bearing seat is provided with a slider, which slides along the slide rail.

[0012] Preferably, the base has several limiting grooves for installing optical fibers.

[0013] Compared with the prior art, the present invention has the following beneficial effects: With the cooperation of the pressing unit and the base, stable and non-destructive fixation of optical fibers is achieved, avoiding the shaking caused by manual handling.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] This utility model embodiment proposes an automatic fiber stripping device, comprising: Base plate 1; The support frame 4 has a base 401 for installing optical fibers at its bottom and a pressing unit at its top for fixing the optical fibers to the base 401. The fiber stripping unit includes a mounting base 3, a blade 702, and a drive assembly disposed between the mounting base 3 and the blade 702. The drive assembly is used to drive the blade 702 to move toward or away from the base 401. The moving unit is located between the base plate 1 and the mounting base 3 and is used to drive the fiber stripping unit to move along the fiber axis to strip the cladding of the fiber.

[0020] In this embodiment, as Figure 1 As shown, the support frame 4 is located in the middle of the base plate 1. When processing optical fibers, the optical fibers are directly placed on the base 401 located at the bottom of the support frame 4. Since the base 401 has a certain length, several optical fibers can be distributed on the base 401 at intervals to achieve batch processing in subsequent operations. Specifically, the base 401 is provided with several limiting grooves 402 for installing optical fibers. Under the action of the limiting grooves 402, a self-positioning function is achieved, which simplifies the operation steps during placement and saves time.

[0021] Once the optical fiber is placed on the base 401, it can be pressed by the pressing unit to fix it on the base 401, achieving stable and non-destructive fixation of the optical fiber and avoiding shaking caused by manual handling.

[0022] like Figure 1 The enlarged schematic diagram shows that after the optical fiber is fixed, the end of the optical fiber is placed on the moving unit. The driving component can precisely control the downward stroke and force of the blade 702 to ensure that the blade 702 only cuts the cladding and does not scratch the fragile quartz fiber core. After the blade 702 presses and cuts the optical fiber, the moving unit drives the entire fiber stripping unit to move along the optical fiber axis, so as to realize the synchronous cutting of batch optical fibers.

[0023] Specifically, depending on the different processing operations of the optical fiber, a fiber stripping unit and a moving unit can be set on the same side of the base plate 1, or a fiber stripping unit and a moving unit can be set on both sides of the base plate 1. The entire operation process can be automated by connecting the pressing unit, the fiber stripping unit and the moving unit to a programmable logic controller (PLC). The controller can be used to adjust the pressing pressure, the length of fiber stripped and the sequential operation of each unit.

[0024] Based on the above solution, the structure of the pressing unit is optimized, such as... Figure 3 As shown, the pressing unit includes: The first transmission rod 6 is located at the top of the support frame 4; Press plate 601 is located at the telescopic end of the first transmission rod 6 and corresponds one-to-one with the base 401.

[0025] The first transmission rod 6 is a cylinder. The fixed end of the first transmission rod 6 is fixedly installed on the top of the support frame 4, and its telescopic end is installed downward. When the telescopic end extends, it drives the pressing plate 601 to move towards the base 401, thereby fixing the optical fiber on the base 401. This prevents the optical fiber from shifting or shaking during the axial movement and stripping process, ensuring the straightness of the movement trajectory of the blade 702 and the neatness of the stripping edge.

[0026] Because the surface of quartz optical fiber is smooth and fragile, specifically, a flexible pressing layer 602 is provided at the bottom of the pressing plate 601. The flexible pressing layer 602 is made of flexible materials such as rubber and silicone, which has high compliance and buffering capacity. When the pressing plate 601 is pressed down, the flexible pressing layer 602 can adaptively conform to the surface of the optical fiber, avoiding the indentations and scratches that may be caused by the rigid pressing plate 601.

[0027] Based on the above scheme, the structure of the driving component is optimized, such as... Figure 3 As shown, the driving component includes: The second transmission rod 7 is located on the side of the mounting base 3; Mounting plate 701 is located at the telescopic end of the second transmission rod 7, and blade 702 is located at the bottom of mounting plate 701.

[0028] The second transmission rod 7 is a cylinder. By controlling the stroke of the second transmission rod 7, the extension and retraction of its telescopic end can directly control the up and down movement of the mounting plate 701. The entire transmission process has a short transmission chain, which can achieve high-precision positioning. In the frequent fiber stripping process, it can ensure that the depth of the blade 702 cutting into the sheath is consistent each time the fiber is stripped. At the same time, the blade 702 can be fixed to the mounting plate 701 by screws, making the installation, disassembly and replacement of the blade 702 more convenient.

[0029] Because the fiber cladding has a certain degree of hardness and toughness at room temperature, the blade 702 needs to apply considerable force to cut and peel off the cladding during cold stripping. This process is prone to vibration and stress concentration. Specifically, the bottom of the mounting plate 701 is equipped with a heating unit 703 for heating the blade 702. The heating unit 703 heats the blade 702, and when the blade 702 contacts the fiber cladding, the heat is rapidly conducted, locally softening or even slightly melting the cladding material. This allows the blade 702 to separate the cladding with minimal cutting force. At the same time, heat-assisted stripping allows the cladding material to undergo controllable melting and shrinkage during separation, resulting in a smoother and neater stripping edge, thus improving the quality of the optical fiber. The heating unit 703 is a heating plate in the prior art, and the heating method includes heating wires and heating tubes.

[0030] Based on the above scheme, the structure of the mobile unit is optimized, such as... Figure 1 As shown, the moving unit includes: Fixing plate 5, the fixing plate 5 is set on the base plate 1; The bearing seat 2 is slidably mounted on the fixed plate 5, and the mounting seat 3 is fixedly mounted on the bearing seat 2; A lead screw 502 is rotatably mounted on a base plate 1, and a bearing seat 2 is connected to the lead screw 502 in a transmission manner. A transmission device 501 is provided on the side of the base plate 1, and the output shaft of the transmission device 501 is connected to the end of the lead screw 502.

[0031] After the blade 702 cuts the optical fiber, the actuator 501 is activated, causing the lead screw 502 to rotate. This causes the lead screw 502 to move the carrier 2 on the fixed plate 5, which in turn causes the blade 702 to separate the optical fiber cladding. The actuator 501 is a forward and reverse motor that can control the lead screw 502 to rotate in both directions, thereby driving the carrier 2 to complete the cycle of forward alignment, stopping at the end position, and backward stripping.

[0032] Specifically, such as Figure 2 As shown, the fixed plate 5 is provided with a slide rail 504, and the bottom of the support seat 2 is provided with a slider 503. The slider 503 is slidably disposed on the slide rail 504. With the cooperation of the slide rail 504 and the slider 503, it can be ensured that the support seat 2 always moves linearly along the length direction of the slide rail 504, avoiding deviation or shaking of the peeling path.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
