Description

Technical Field

[0001] This utility model relates to the field of optical fiber coating stripping technology, specifically to a general-purpose optical fiber coating thermal stripping device. Background Technology

[0002] In the field of fiber laser manufacturing, such as fiber performance testing, fiber device manufacturing, and laser system assembly, it is usually necessary to remove the coating layer on the surface of the fiber. The quality of the fiber coating stripping and the effect of coating removal have a significant impact on subsequent fiber splicing or testing.

[0003] In related technologies, fiber optic coating removal methods include cold stripping, hot stripping, laser stripping, and chemical stripping. Cold stripping typically uses Miller clamps or manual stripping with blades. Miller clamp stripping lacks versatility and is unsuitable for removing coatings from large-size fibers, and the stripped edge is uneven, easily damaging the fiber. While manual stripping with blades has greater versatility, it suffers from low stripping efficiency, poor stripping quality, and easy scratching of the fiber. In existing hot stripping devices, the upper and lower blades are usually designed with V-grooves. During fiber coating removal, improper adjustment of the V-groove size or inappropriate pressure of the cover plate often leads to unsatisfactory stripping results and coating removal. Furthermore, when stripping coatings from octagonal cladding fibers, the cladding is easily damaged. Additionally, when switching between different fiber sizes for coating removal, it is impossible to accurately adjust the appropriate blade position in a short time, requiring repeated calibration, which is time-consuming and labor-intensive. Laser stripping equipment is expensive, and large-size optical fibers produce a lot of burn residue during coating removal. Chemical stripping uses an immersion etching method, which cannot precisely control the etching depth of the coating and generates waste liquid. Utility Model Content

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this utility model based on the specific circumstances.

[0030] In this embodiment of the utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The following is combined with Figures 1-4This invention describes a general-purpose optical fiber coating thermal stripping device, comprising a base 1, a clamping assembly 3, a heating assembly 4, and a cutting assembly 2. The clamping assembly 3 is slidably disposed on the base 1 and is used to clamp the optical fiber and drive it to move. The heating assembly 4 is fixedly disposed on the base 1 and is used to heat the optical fiber coating. Located at one end of the heating assembly 4 and between the clamping assembly 3 and the cutting assembly 2, the cutting assembly 2 is used to cut the coating on the outside of the optical fiber, so that the coating is stripped off during the fiber's movement. In some scenarios, it is necessary to remove the coating on the outside of the optical fiber. In this embodiment, the cutting assembly 2 processes a cut in the coating on the outside of the optical fiber, the heating assembly 4 heats the coating, and the clamping assembly 3 clamps and drives the optical fiber. During the fiber's movement, the coating is stripped off at the cut. The overall device structure is simple and easy to manufacture.

[0033] Understandably, the heating component 4 is used to heat the coating segment at the location to be removed. After heating, the coating layer becomes loose. When the optical fiber is pulled by the clamping component 3, the segment to be stripped is quickly stripped by the limiting of the cutting component 2, which improves the stripping efficiency and stripping quality.

[0034] Furthermore, the cutting component 2 is located between the heating component 4 and the clamping component 3. The clamping component 3 is movable. The cutting component 2 cuts a notch on the coating layer outside the optical fiber, that is, the notch is located between the heating component 4 and the clamping component 3, which facilitates the peeling of the coating layer from the notch position.

[0035] According to one embodiment provided by this utility model, such as Figure 2 , Figure 3 As shown, the heating assembly 4 includes a heating base and a heating cover plate. The heating base has a heating block 40 with a limiting groove. The heating cover plate is hinged to one side of the heating base via a hinge. A flexible pressure strip 44 is provided on the heating cover plate so that when the heating cover plate is closed, the flexible pressure strip 44 is located within the limiting groove to limit the optical fiber. During heating, uniform and effective heating of the area to be heated is required. In this embodiment, the limiting groove formed on the heating block 40 allows the optical fiber body to be located within the limiting groove, achieving uniform heating of the coating layer and facilitating subsequent stripping operations.

[0036] It is understandable that the heating block 40 forms a limiting groove, which enables it to heat multiple surfaces of the optical fiber body, thereby improving the uniformity of heating and achieving uniform heating of the optical fiber body, thus improving heating efficiency.

[0037] In a specific configuration, the heating block 40 includes a first heating part 41, a second heating part 42, and a third heating part 43. The first heating part 41 is located in a groove on the upper surface of the heating base. The second heating part 42 and the third heating part 43 are located on both sides of the first heating part 41 to form a "U"-shaped limiting groove structure, in which the optical fiber body can be placed.

[0038] Furthermore, the first heating unit 41, the second heating unit 42, and the third heating unit 43 are electrically heated components, and the heating of each heating unit is controlled electronically. Of course, the first heating unit 41, the second heating unit 42, and the third heating unit 43 can also be heated by other methods. For example, heating can also be achieved through a heating liquid.

[0039] In practical applications, the flexible pressure strip 44 is a rubber pressure strip, and the length of the rubber pressure strip is the same as the length of the limiting groove, so that the flexible pressure strip 44 matches the limiting groove, thereby limiting the optical fiber in the limiting groove.

[0040] like Figure 2 As shown, the heating cover plate is connected to one side of the heating base via a hinge shaft, allowing the heating cover plate to rotate around the hinge shaft to close and open the upper limit groove of the heating base. The size of the flexible pressure strip 44 matches the size of the limit groove, so that when the heating cover plate is closed, the flexible pressure strip 44 is located in the limit groove and can prevent the optical fiber from shaking significantly.

[0041] In a specific configuration, the heating cover has a protruding edge on the side away from the hinge position. The protruding edge protrudes from the outer wall of the heating base and serves as a gripping area for manual opening and closing, making it easy to hold and open / close the heating cover.

[0042] In a specific embodiment, the heating cover plate is provided with a locking part, which is used to lock the heating cover plate when it is closed. The locking part facilitates the closing of the heating cover plate and facilitates subsequent heating of the optical fiber body and stripping of the coating layer.

[0043] Understandably, the locking mechanism enables the heating cover to be locked when closed, improving the stability of the device and making the entire device more stable when peeling off the coating on the outside of the optical fiber.

[0044] In a specific configuration, the locking mechanism includes a first magnet 253 and a second magnet 242. The first magnet 253 is mounted on the heating base, and the second magnet 242 is mounted on the heating cover. When the heating cover is closed, the first magnet 253 and the second magnet 242 can adhere to each other and attract to lock together, thus locking the heating cover. The locking mechanism facilitates the opening and closing of the heating cover, improving its convenience. Alternatively, the locking mechanism can be a snap-fit ​​structure.

[0045] In a specific embodiment, the heating base is further provided with a heating control module (not shown in the figure), a temperature adjustment unit 45, and a temperature indicator light 46. The heating control module is electrically connected to the heating block 40, and both the temperature adjustment unit 45 and the temperature indicator light 46 are electrically connected to the heating control module. The temperature adjustment unit 45 is used to adjust the temperature of the heating block 40, and the temperature indicator light 46 is used to indicate whether the temperature has reached the preset temperature. During heating, since the optical fiber is entirely located inside the heating assembly 4, it is difficult to make a direct judgment. In this embodiment, the temperature adjustment unit 45 can be used to adjust the heating temperature, and the temperature indicator light 46 can be used to indicate whether the preset temperature has been reached.

[0046] Understandably, the temperature indicator light 46 can switch colors to indicate whether a predetermined stable temperature has been reached. Specifically, once the heating temperature rises to the set temperature, the temperature indicator light 46 will change from red to green.

[0047] In a specific configuration, the heating block 40 is an electrically driven heating component, such as a resistance temperature detector (RTD) component. The heating control module is located inside the heating base. The heating control module is used to control the input current or directly adjust the resistance value of the heating block 40 to control the heating amount.

[0048] In practical applications, the temperature adjustment unit 45 and the temperature indicator light 46 are located on the same outer wall surface of the heating base. This arrangement facilitates the installation of the components and reduces the difficulty of device fabrication.

[0049] According to one embodiment of the present invention, the cutting assembly 2 includes a first fixture 25, a second fixture 24, a first cutter head 23, a second cutter head 22, and a positioning tube 21. The first fixture 25 is fixedly disposed at one end of the heating base. A first mounting groove 251 is provided at one end of the first fixture 25 near the heating base, and a positioning hole 252 is provided at the other end of the first fixture 25 away from the heating base. The second fixture 24 is fixedly disposed at one end of the heating cover plate. A second mounting groove 241 is provided on one side of the second fixture 24. When the heating cover plate is closed, the mounting groove is located directly above the second mounting groove 241. The first cutter head 23 is installed in the first mounting groove 251. The second cutter head 22 is installed in the second mounting groove 241 so that when the heating cover plate is closed, the first cutter head 23 and the second cutter head 22 cooperate to cut the fiber coating layer. The positioning tube 21 is installed in the positioning hole 252, and the positioning hole 252 is coaxially arranged with the limiting groove. By connecting the first fixture 25 to the heating base and the second fixture 24 to the heating cover, the coating can be cut simultaneously when the heating cover is closed, thus improving the overall compactness of the device.

[0050] In a specific configuration, the first fixture 25 is provided with a first mounting groove 251 for mounting the first cutter head 23, and the second fixture 24 is provided with a second mounting groove 241 for mounting the second cutter head 22. When the heating cover is closed, the first cutter head 23 and the second cutter head 22 cooperate to cut the outer coating layer of the optical fiber, so that a cut is formed on the cut layer on the outer side of the optical fiber, which facilitates the peeling of the coating layer at the predetermined position.

[0051] In a specific embodiment, the first cutter head 23 and the second cutter head 22 are equipped with blades 231, each blade having a semi-circular cutting edge 233. The cutting edge has a cutting edge for cutting, and the overall structure of the cutting edge is semi-circular. This allows the first cutter head 23 and the second cutter head 22 to form a circular cutting edge when they are engaged, which cuts the coating layer to create a slit. Specifically, the cutting edge is set to the inner diameter of the coating layer, so that the coating layer can be precisely cut under the pressure of the first cutter head 23 and the second cutter head 22, avoiding damage to other coating layers and improving the quality of peeling.

[0052] In specific settings, such as Figure 5 , Figure 6 As shown, the first cutter head 23 and the second cutter head 22 are both L-shaped main body structures 232. The blade 231 is located at the bottom of the main body structure 232. Semi-circular grooves are opened on the first cutter head 23 and the second cutter head 22 at the cutting edge position. The semi-circular grooves 234 are conducive to the peeling of the coating layer.

[0053] According to one embodiment of this utility model, the positioning tube 21 is a metal tube, and the optical fiber inlet end of the positioning tube 21 has a horn-shaped inlet structure. The horn-shaped inlet structure facilitates the insertion of the optical fiber and improves the efficiency of optical fiber installation.

[0054] It is understandable that the positioning tube 21 is coaxially set with the limiting groove, and the horn-shaped structure facilitates the insertion of optical fibers, giving them a guiding function.

[0055] In a specific embodiment, the first fixture 25 is provided with a first positioning groove, which extends from the positioning hole 252 to a position close to the first mounting groove 251. The second fixture 24 is provided with a second positioning groove on the side that contacts the first fixture 25. The second positioning groove is used to cooperate with at least a portion of the first positioning groove to form a positioning cavity, and one end of the positioning tube 21 is located inside the positioning cavity. The positioning tube 21 is used for the optical fiber body 5 to pass through and to stabilize the optical fiber body 5 when pulled. In this embodiment, the formation of the positioning cavity makes the positioning tube 21 more stable during stripping, thereby improving the overall stability of the device.

[0056] In a specific configuration, one end of the positioning tube 21 is located inside the positioning hole 252, and the other end of the positioning tube 21 is located inside the positioning cavity, so as to achieve positioning of the positioning tube 21, thereby ensuring the stability of the installation of the positioning tube 21 and avoiding shaking during the movement of the optical fiber body 5.

[0057] According to one embodiment provided by this utility model, such as Figure 1 , Figure 4 As shown, a guide rail 31 is provided on the base 1, and the clamping assembly 3 slides in cooperation with the guide rail 31. The clamping assembly 3 includes a slider 32, a connecting block 33, and a clamping cover plate 35. The slider 32 is slidably connected to the guide rail 31. The connecting block 33 is provided on the slider 32, and a clamping block 34 is provided on the connecting block 33. A clamping groove is formed along the axial direction of the clamping block 34. The clamping cover plate 35 is hinged to one side of the connecting block 33 by a hinge. A flexible pressing block 36 is provided on the clamping cover plate 35 so that when the clamping cover plate 35 is closed, the flexible pressing block 36 is located in the clamping groove to clamp the optical fiber. The slider 32 can slide along the guide rail 31, thereby driving the connecting block 33 to move. The clamping groove on the connecting block 33 is used to clamp the optical fiber, so that when the connecting block 33 moves, it can drive the clamped optical fiber to move, thereby realizing the removal of the coating layer.

[0058] In the specific configuration, the base 1 has a T-shaped structure, and the guide rail 31 is located on the extension section of the base 1. The flexible clamping block 36 on the clamping cover plate 35 can cooperate with the clamping groove to clamp the optical fiber body 5. After the optical fiber body 5 is clamped, the drive slider 32 moves along the guide rail 31, thereby realizing the movement of the optical fiber body 5. Specifically, a magnet is provided on the clamping cover plate 35, and a corresponding magnet is provided on the connecting block, so that the clamping cover plate and the connecting block are locked together by the mutual attraction between the magnets.

[0059] In a further example, the clamping block 34 is slightly higher than the upper surface of the connecting block 33, which allows the flexible clamping block 36 to fill the entire clamping groove when pressed down, thereby clamping the optical fiber body 5. Specifically, the flexible clamping block 36 is a rubber clamping block, which is arranged along the extension direction of the clamping groove, so that the flexible clamping block 36 can fill the entire clamping groove.

[0060] In a specific embodiment, the clamping block 34 is a polygonal cylindrical structure. Each side of the clamping block 34 along its axial direction is provided with a V-shaped clamping groove, and each clamping groove on each side has a different groove size. Different groove sizes can achieve the clamping of optical fiber bodies 5 of different specifications, so as to be suitable for the stripping of coating layers of optical fibers of different specifications.

[0061] In a specific embodiment, the clamping block 34 is a hexagonal cylindrical structure, which is fixedly connected to the connecting block 33 by bolts. Each of the six cylindrical surfaces is machined with a V-shaped clamping groove, and the groove opening size on each surface is different, thus enabling the stripping of optical fibers of different thicknesses. The bolt connection facilitates the disassembly and replacement of the clamping block 34, and is beneficial for pressing the optical fiber bodies 5 of different thicknesses.

[0062] like Figure 8 As shown, the specific stripping method of the general-purpose optical fiber coating thermal stripping device provided above is described below. The specific steps are as follows:

[0063] S100. Based on the required dimensions of the optical fiber body 5 to be processed, select a suitable size positioning tube 21, a first cutting head 23, a second cutting head 22, and a V-groove of suitable depth on the clamping block 34, and install them accordingly; then insert the octagonal clad optical fiber to be stripped into the positioning tube 21 and place the optical fiber inside the lower cutting edge. Ideally, the optical fiber should extend 5-6 cm beyond the cutting edge.

[0064] S200, cover with the heating cover and manually press to apply appropriate pressure to the optical fiber body 5 inside the blade, so as to cut the optical fiber coating layer and form a cut at the cutting position.

[0065] S300, the temperature adjustment unit 45 selects a suitable heating temperature to heat the optical fiber coating. After the temperature indicator light 46 changes from red to green, the clamping assembly 3 pulls the optical fiber body 5 to move it along the guide rail 31, thus performing the stripping operation on the optical fiber coating. Figure 7 This is a schematic diagram of the stripping of the optical fiber coating.

[0066] As can be seen from the above embodiments, the universal optical fiber coating thermal stripping device provided by this utility model can completely cut the optical fiber coating without damaging the optical fiber cladding, has good stripping quality and a more thorough coating removal effect, can strip the coating of optical fibers of different sizes, and the components are easy to replace and have strong versatility. Furthermore, the upper and lower cutting heads have semi-circular cutting edges 233, which can completely cut the optical fiber coating without damaging the optical fiber cladding.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
