Description

Technical Field

[0001] This utility model relates to the technical field of optical fiber stripping devices, and specifically discloses a cutting tool adjustment mechanism for an optical fiber thermal stripping machine. Background Technology

[0002] In the laying and production of optical fibers, fusion splicing is often required between ordinary and special optical fibers. Before fusion splicing, the surface coating is first removed, then the fibers are cut, and finally, they are fused together.

[0003] Currently, optical fiber fusion splicing typically involves using a thermal stripper to remove the coating layer from the optical fiber. However, the blades in commercially available optical fiber thermal strippers are fixed and cannot be adjusted. This means that once the blade position is adjusted, it cannot be changed, limiting its application to only one type of fiber and restricting its functionality. For example, invention patent application number 201811533891.1 discloses an optical fiber thermal stripping clamp device, including a pressure cap, a base, two clamping covers, and a blade assembly. The pressure cap and the two clamping covers are hinged to the base, with the two clamping covers positioned on either side of the pressure cap. A stripping channel for placing the optical fiber is provided between the pressure cap, the two clamping covers, and the base. The blade assembly includes an upper blade and a lower blade. The upper blade is fixedly connected to the pressure cap and has a first V-groove. The lower blade is fixedly connected to the base and its position corresponds to that of the upper blade. The lower blade groove has a second V-groove. The first V-groove of the upper blade and the second V-groove of the lower blade together form a cutting hole that fits the optical fiber core. The fiber optic thermal stripping pliers disclosed in this patent use fixed upper and lower blades, which results in a limited range of applicability for the entire fiber optic thermal stripping machine, making it unable to effectively strip the coating layers of optical fibers with different thicknesses ranging from 50 to 1000 μm. Utility Model Content

[0004] The purpose of this invention is to provide a fiber optic thermal stripper blade adjustment mechanism to achieve precise adjustment of the blades in the thermal stripper, enabling it to be effectively applied to various types of optical coatings and thus having a wider range of applications.

[0005] This utility model is achieved through the following technical solution:

[0006] A fiber optic thermal stripping machine cutter adjustment mechanism includes a clamp base, a clamp cover plate, a lower cutter head, and an upper cutter head. The lower cutter head is fixedly mounted at the end of the clamp base, and the upper cutter head is mounted at the end of the clamp cover plate directly above the lower cutter head. An adjustment knob is rotatably mounted in the clamp cover plate above the upper cutter head. An indicator component is provided between the adjustment knob and the clamp cover plate. The upper cutter head is movably mounted up and down via a guide post on the clamp cover plate. A threaded cap is provided in the upper cutter head, and an adjustment threaded rod that interacts with the threaded cap is provided at the lower end of the adjustment knob.

[0007] As a further feature of the above solution, corresponding positioning grooves are provided on both the lower and upper cutting heads.

[0008] As a further feature of the above scheme, the marking component includes a pointer disposed on the adjustment knob and a scale disposed on the clamp cover plate surrounding the adjustment knob.

[0009] As a further feature of the above solution, the end of the clamp cover plate has an integrally formed semicircular portion protruding outward, the adjustment knob is concentrically rotated in the semicircular portion, and the guide post is disposed at both ends of the adjustment knob.

[0010] As a further feature of the above solution, one side of the fixture base is provided with a connecting part that is flexibly connected to the fixture cover plate.

[0011] The fiber optic thermal stripping machine blade adjustment mechanism disclosed in this patent allows for rapid adjustment of the upper blade position to accommodate different fiber types and thicknesses during use. Specifically, rotating the adjustment knob in the fixture cover causes the adjusting threaded rod to rotate. The thread engagement between the threaded rod and the threaded cap, combined with the guiding action of the guide post, causes the upper blade to move up and down. During adjustment, the marking component allows for quick identification of the upper blade's suitability for the corresponding fiber. Once adjusted, the coating removal operation can be performed on fibers of different types and thicknesses. Beneficial effects

[0012] 1. This patent allows the height of the upper blade to be adjusted by operating the adjustment knob, thereby enabling the effective removal of coatings on different optical fibers and making its application range wider.

[0013] 2. This patent, through the design of the marking component, can reflect the height of the blade adjustment in real time, making it easier for users to quickly adjust to the appropriate state according to the fiber model for use.

[0014] 3. This patent provides a guiding function by opening positioning grooves on both the upper and lower blades, which can better perform the stripping process during the coating removal process and ensure the stripping effect of the fiber coating. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-3 This application will be described in detail with reference to the embodiments. Example

[0021] Example 1 discloses a cutter adjustment mechanism for a fiber optic thermal stripper, which will be described below in conjunction with the entire fiber optic thermal stripper. The fiber optic thermal stripper includes a clamp base 1 and a clamp cover plate 2. One side of the clamp base 1 is provided with an upwardly protruding connecting part 101, and then the side end of the clamp cover plate 2 is rotatably connected to it by a pin.

[0022] A lower cutter head 3 is fixedly connected to one end face of the fixture base 1 by screws. An upper cutter head 4 is provided on the end face of the fixture cover plate 2 directly above the lower cutter head 3. A V-shaped positioning groove 5 is provided in the middle of both the lower cutter head 3 and the upper cutter head 4. When the fixture cover plate 2 is closed on the upper surface of the fixture base 1, the positioning groove 5 on the lower cutter head 3 and the upper cutter head 4 can clamp the optical fiber, and the cutting edge extends into the interior of the optical fiber coating layer.

[0023] To adjust the position of the upper cutter head 4, a semi-circular portion 201 is integrally formed protruding outward from the end of the clamping cover plate 2 above the upper cutter head 4. On the upper surfaces of the semi-circular portion 201 and the clamping cover plate 2, scales 202 suitable for corresponding coarseness sizes are arranged in a circular array centered on the center of the semi-circular portion 201. An adjustment knob 5 is rotatably mounted at the center of the semi-circular portion 201, and a pointer 501 pointing to the scale 202 is provided on the upper surface of the adjustment knob 5.

[0024] Vertically downward guide posts 6 are provided at both ends of the semicircular portion 201, and guide holes matching the guide posts 6 are provided at both ends of the upper cutter head 4. The guide posts 6 are then inserted into the corresponding guide holes, and springs connected to the upper cutter head 4 and the semicircular portion 201 are respectively sleeved around the guide posts 6. A threaded cap 7 is fixedly provided inside the upper cutter head 4, and an adjusting threaded rod 8 adapted to the threaded cap 7 is connected to the lower end of the adjusting knob 5. When the adjusting knob 5 is rotated, the upper cutter head 4 will move vertically up and down along the guide posts 6 due to the action between the adjusting threaded rod 8 and the threaded cap 7, thereby changing the distance between the upper cutter head 4 and the lower cutter head 3, thus enabling the thermal stripping of optical fibers of different thicknesses.

[0025] The specific usage method and working principle of the optical fiber thermal stripping machine disclosed in Embodiment 1 are as follows:

[0026] First, adjust the upper cutter head 3 to the highest position by adjusting the knob 5, then open the clamp cover plate 2, put the optical fiber into the clamp base 1 and close the clamp cover plate 2.

[0027] The second step is to rotate the adjustment knob 5 according to the type or thickness of the optical fiber. Then, under the action of the adjusting threaded rod 8 and the threaded cap 7, the upper cutter head 3 moves vertically downward. During the adjustment process of the adjustment knob 5, each time the pointer 501 rotates through a scale 202, it indicates that the upper cutter head 3 has moved down by 0.01mm, until the pointer 501 points to the corresponding scale 202 position. At this time, the height of the upper cutter head 3 is greater than the optical fiber cladding and less than the optical fiber coating (that is, the blade part at the positioning groove 5 extends into the inner bottom layer of the optical fiber coating, but does not contact the inner core of the optical fiber).

[0028] The third step is to heat the optical fiber through the heating element in the fixture base 1 to melt it, and then pull the optical fiber out from the inner and outer peripheries, so that the coating layer on the surface of the optical fiber can be peeled off.

[0029] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
