Description

Technical Field

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

[0002] Since a coating layer needs to be wrapped around the fiber core during optical fiber manufacturing to protect the fiber and maintain its optical performance, and this coating layer needs to be removed in subsequent processes such as splicing and testing, an optical fiber coating thermal stripping device is established. This device softens the coating layer by heating and then uses mechanical force to quickly and accurately strip the coating layer, avoiding damage to the fiber core and ensuring the efficiency and quality of subsequent optical fiber processing. This also meets the standardized requirements for optical fiber processing in fields such as optical fiber communication and sensing.

[0003] A search revealed Chinese patent publication number CN205880276U, which discloses a thermal stripping device for optical fiber coatings. The device includes a clamping cavity and a heating cavity installed side-by-side. The clamping cavity includes a clamping cavity base and a clamping cavity flap connected to the base and capable of opening upwards. The top surface of the clamping cavity base has N clamping slots. The heating cavity includes a heating cavity base and a heating cavity flap connected to the base and capable of opening upwards. The top surface of the heating cavity base and the bottom surface of the heating cavity flap are correspondingly provided with N optical fiber slots. N sets of blades are provided inside the heating cavity near one end of the clamping slots. This invention has multiple clamping slots, allowing simultaneous stripping of the coating from both ends of the optical fibers to be spliced. Multiple sets of blades are configured, and each set can be selected and replaced as needed. This allows for the simultaneous stripping of the coating from multiple optical fibers with the same cladding diameter, or from multiple optical fibers with different cladding diameters.

[0004] The aforementioned patent has the following shortcomings: When peeling off the fiber coating, the existing device requires manual pulling of the clamp to move the fiber. However, due to the difficulty in maintaining a stable force and speed applied by the operator, the fiber is subjected to uneven force, which can easily cause micro-bending or breakage of the fiber core, affecting the fiber transmission performance. At the same time, manual operation relies on the experience of the operator. Differences in operation between different operators, such as differences in force and speed, can cause inconsistencies in the peeling length and residual amount of the coating, affecting the consistency of processing and making it difficult to meet the requirements of standardized production.

[0005] To address this, a thermal stripping device for optical fiber coating is proposed. Utility Model Content

Therefore, the drawings and description are considered exemplary in nature and not restrictive.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] Example 1:

[0037] like Figures 1 to 5 As shown, a thermal stripping device for optical fiber coating includes a body 1, and further includes:

[0038] Heating cover 12 is rotatably connected to the top of the body 1. Electric heating plate 14 is fixed on one side of heating cover 12 and the top of the body 1. Blade 16 is fixed to the side of heating cover 12 and the side of body 1 by bolts.

[0039] The sliding structure 4 is set on one side of the top of the body 1. The sliding structure 4 includes a bottom cover 402 that is engaged with the bottom of the body 1. Guide rods 403 are fixed on both sides inside the body 1. A movable seat 405 is slidably connected to the outer side of the guide rods 403. A movable table 401 is fixed on the top of the movable seat 405. A transmission component is set inside the body 1.

[0040] A fixed platform 6 is fixed to the top of the movable platform 401. A fixed cover 10 is rotatably connected to one side of the top of the fixed platform 6. A limit sleeve 7 is fixed to the top of the fixed platform 6. A pressure sleeve 8 is provided inside one side of the fixed cover 10.

[0041] The pressing structure 9, used to adjust the distance between the limiting sleeve 7 and the pressure sleeve 8, is located inside one side of the fixed cover 10.

[0042] Separation structures 3, used to separate the optical fiber coating from the heating plate 14, are respectively installed inside the heating cover 12 and the body 1.

[0043] A first magnetic buckle 13 is fixed to the top of one side of the heating cover 12. A first magnetic groove 2 that is magnetically connected to the first magnetic buckle 13 is installed on the side of the top of the body 1. A second magnetic buckle 11 is fixed to the top of one side of the fixed cover 10. A second magnetic groove 5 that is magnetically connected to the second magnetic buckle 11 is installed on the side of the top of the fixed platform 6. A control panel 15 is fixed to the other side of the top of the body 1. A battery compartment 17 is installed at the bottom inside the body 1.

[0044] In this embodiment, the device is powered by the battery compartment 17 during use. Heating and movement parameters are set through the operation control panel 15. The heating cover 12 is rotated to separate the first magnetic buckle 13 from the first magnetic suction groove 2 and open it. The fixing cover 10 is rotated to separate the second magnetic buckle 11 from the second magnetic suction groove 5 and open it. The optical fiber to be processed is placed on the surface of the heating plate 14 and the optical fiber is located inside the limiting sleeve 7. The fixing cover 10 and the heating cover 12 are closed. The position of the optical fiber is fixed by the limiting sleeve 7 and the pressure sleeve 8. At the same time, the heating plate 14 adheres to the optical fiber coating layer and heats it, so that the optical fiber coating layer softens due to heat. The sliding structure 4 drives the fixing stage 6 to move, so that the optical fiber leaves the inside of the fixing cover 10. At the same time, the blade 16 peels off the softened coating layer on the surface of the optical fiber.

[0045] like Figures 1 to 3 As shown, the transmission assembly includes a lead screw 404 rotatably connected inside the machine body 1 and meshing with the movable seat 405. A drive motor 406 with its output shaft end connected to the lead screw 404 is fixed on one side inside the machine body 1. The movable seat 405 extends to the top of the machine body 1 and is connected to the movable platform 401. The guide rods 403 are symmetrically distributed on the vertical center line of the movable seat 405.

[0046] In this embodiment, when it is necessary to move the optical fiber to peel off the coating, the drive motor 406 is started through the control panel 15, which drives the lead screw 404 to rotate. Since the lead screw 404 meshes with the moving seat 405, the moving seat 405 slides along the guide rod 403 and drives the moving stage 401 to move. The moving stage 401 drives the fixed stage 6 and the optical fiber fixed above to move synchronously. During the movement of the optical fiber, the blade 16 cuts the softened coating, while the heating plate 14 continues to maintain a heating state to ensure that the coating is always in a softened state for easy peeling. Then the optical fiber continues to move until the coating is completely separated from the fiber core, thereby realizing the automatic peeling of the coating. This avoids the problem of uneven force caused by manually pulling the optical fiber to a certain extent and ensures the stability of the optical fiber movement speed and the peeling process.

[0047] Example 2:

[0048] A thermal stripping device for optical fiber coating is provided in this embodiment, which is improved upon embodiment 1 as follows: Figure 4 As shown, the pressing structure 9 includes a screw 902 threadedly connected to the inside of one side of the fixed cover 10. A knob 901 is fixed to one side of the screw 902. A pressure plate 904 connected to the pressure sleeve 8 is rotatably connected to the other side of the knob 901. A guide post 903 slidably connected to the fixed cover 10 is fixed to one side of the pressure plate 904. Four sets of guide posts 903 are provided, and the four sets of guide posts 903 are arranged in a rectangle on one side of the pressure plate 904.

[0049] In this embodiment, when it is necessary to adjust the gap between the limiting sleeve 7 and the pressure sleeve 8 according to the fiber size, the screw 902 is rotated by rotating the knob 901, so that the screw 902 moves to one side of the fixing cover 10 through the thread engagement. At the same time, the screw 902 pushes the pressure sleeve 8 closer to the limiting sleeve 7 through the pressure plate 904. The gap between the pressure sleeve 8 and the limiting sleeve 7 is adjusted according to the fiber diameter so that the gap is just adapted to the fiber size, thereby realizing the fixing of fibers of different specifications. To a certain extent, the adaptability of the device to fibers of different sizes is improved, and the fiber will not be deviated during the movement. The guide post 903 slides along the fixing cover 10 to ensure the stability of the movement direction of the pressure plate 904.

[0050] like Figure 5 As shown, the separation structure 3 includes a fixed frame 302 fixed inside the heating cover 12 and the body 1 respectively. A telescopic spring 303 is fixed at the bottom end of the fixed frame 302. A movable frame 304 is fixed at the bottom end of the telescopic spring 303. Push frames 301 are fixed on both sides of the bottom end of the movable frame 304. The movable frame 304 forms a sliding structure with the heating cover 12 and the body 1 respectively. The movable frame 304 forms a telescopic structure with the heating plate 14 through the telescopic spring 303.

[0051] In this embodiment, when the heating cover 12 rotates and closes towards the body 1, the pusher 301 is pushed during the closing process of the heating cover 12, pressing the pusher 301 into the body 1 or the interior of the heating cover 12. At this time, the pusher 301 compresses the telescopic spring 303, so that the telescopic spring 303 is in a compressed state. When the coating peeling operation is completed, the heating cover 12 is opened, the pressure of the heating cover 12 on the pusher 301 disappears, the telescopic spring 303 in the compressed state releases its elasticity, and pushes the moving frame 304 to slide along the interior of the body 1 or the heating cover 12. The moving frame 304 drives the pusher 301 to move synchronously, so that the pusher 301 contacts and lifts the coating layer remaining on the surface of the heating plate 14, thereby separating the coating layer from the surface of the heating plate 14. This avoids the coating layer from sticking and affecting the subsequent heating effect to a certain extent, and ensures the cleanliness of the surface of the heating plate 14.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
