These terms are only used to distinguish one element from another. For example, a first element could also be termed a second element, and, similarly, a second element could also be termed a first element, without departing from the scope of the present disclosure.

[0040] Referring to Figures 1 to 9 In some embodiments, a temperature-adjustable optical fiber heating device is provided according to an embodiment of the present application, which comprises a base 100, a V-shaped groove seat 200, an adjusting seat 300, an electrode rod 400, and an adjusting mechanism.

[0041] The V-shaped groove seat 200 is fixedly installed on the upper surface of the base 100, and the V-shaped groove seat 200 is provided with a heating position 210 at the center thereof. The V-shaped groove seat 200 is provided with V-shaped grooves 220 on the left and right sides of the heating position 210. The optical fiber is embedded in the V-shaped grooves 220 and is heated at the heating position 210.

[0042] The adjusting seat 300 is rotatably installed on the upper surface of the base 100 along a vertical axis. The electrode rod 400 is installed on the adjusting seat 300, and the electrode rod 400 has a sharp end facing the heating position 210, which is used for heating the optical fiber at the heating position 210. The adjusting mechanism is used to drive the adjusting seat 300 to rotate to adjust the rotation angle of the electrode rod 400. The materials of the V-shaped groove seat and the base can be bakelite, which has a high mechanical strength, good insulation, heat resistance, and corrosion resistance.

[0043] This invention provides an adjustable temperature zone fiber heating device. A V-groove 220 is used for fiber embedding and positioning, improving processing accuracy. A heating clearance 210 provides sufficient space for the fiber heating position. An adjusting seat 300 is rotatably mounted on the upper surface of the base 100 along a vertical axis, providing the electrode rod 400 mounted on the adjusting seat 300 with rotational adjustment freedom. An adjusting mechanism drives the adjusting seat 300 to rotate, adjusting the rotation angle of the electrode rod 400, thereby achieving angle adjustment of the electrode rod 400. This adjusts the temperature zone and heating position, enabling the device to meet various fiber heating requirements and expanding its applicability.

[0044] Reference Figures 1 to 3 In some embodiments of the present invention, the adjusting mechanism includes a screw 500, and a base 100 is provided with a threaded seat 110 for threaded connection of the screw 500. The threaded seat 110 is provided with a threaded hole adapted to the screw 500. The screw 500 and the adjusting seat 300 are connected by a connecting rope 510, so that when the screw 500 is turned away from the adjusting seat 300, the adjusting seat 300 can be pulled to rotate by the connecting rope 510. The adjusting seat 300 is connected to the V-groove seat 200 or the base 100 by an elastic element 600. Specifically, in this embodiment, both ends of the elastic element 600 are connected to the adjusting seat 300 and the V-groove seat 200. Since the V-groove seat 200 is fixedly connected to the base 100, in some other embodiments, both ends of the elastic element 600 can also be connected to the adjusting seat 300 and the base 100. The rotation direction of the adjusting seat 300 pulled by the connecting rope 510 is opposite to the rotation direction of the adjusting seat 300 driven by the elastic force of the elastic element 600. The adjusting seat 300 is tightened by the tension in two opposite directions from the connecting rope 510 and the elastic element 600, with the connecting rope 510 always in a taut state. When the screw 500 moves away from the adjusting seat 300, the connecting rope 510 pulls the adjusting seat 300 to rotate toward the screw 500. When the screw 500 moves closer to the adjusting seat 300, the elastic element 600 pulls the adjusting seat 300 to rotate away from the screw 500. This achieves the rotational adjustment and position fixation of the adjusting seat 300 without the need for fasteners, making it convenient to adjust the position at any time.

[0045] It is understandable that the elastic element 600 can be a tension spring, with its two ends fixed or hooked onto the adjusting seat 300 and the V-groove seat 200, respectively. Figure 6 As shown, the adjusting seat 300 is provided with a hook hole 313 for the tension spring to hook onto, and the V-groove seat 200 can also be provided with a corresponding structure to facilitate the connection of the tension spring.

[0046] Specifically, the screw 500 has a hollow structure with a central hole 520. The connecting rope 510 enters the screw 500 from the end near the adjusting seat 300 and exits from the end away from the adjusting seat 300, with a limiting structure at the exit end. The limiting structure can be a knot formed at the end of the connecting rope 510, with the knot larger than the central hole 520. Alternatively, the limiting structure can be a structure where the outline of the connecting rope is larger than the central hole 520, preventing the end of the connecting rope 510 from passing through the central hole 520. Similarly, the adjusting seat 300 can also have holes for the connecting rope 510 to pass through. After the connecting rope 510 passes through the corresponding hole, a limiting structure is set up to pull the adjusting seat 300.

[0047] Of course, in some other embodiments, both the screw 500 and the adjusting seat 300 can be provided with an annular structure for the connecting rope 510 to be tied, so as to realize the connection between the connecting rope and the screw 500 and the adjusting seat 300.

[0048] Reference Figures 5 to 7 In some embodiments of the present invention, the adjusting seat 300 includes a base 310 and an electrode seat 320. The base 310 is rotatably mounted on the upper surface of the base 100, and the electrode seat 320 is fixedly connected to the base 310. The electrode seat 320 has an insertion hole 321 for inserting an electrode rod 400. The electrode rod 400 is inserted into the insertion hole 321 and can slide along the insertion hole 321 to adjust its position, thereby adjusting the distance of the electrode rod 400 extending out of the electrode seat 320, that is, adjusting the distance between the electrode rod 400 and the optical fiber, thereby adjusting the heating effect. Specifically, the electrode seat is a good conductor with a certain hardness, such as copper.

[0049] In a further embodiment of the present invention, the electrode holder 320 is provided with a first threaded hole 322 extending into the insertion hole 321. A forward screw 340 is threadedly connected to one end of the insertion hole 321 facing away from the heating clearance 210 to adjust the length of the electrode rod 400 extending out of the electrode holder 320. A fixing screw 330 is threadedly connected to the first threaded hole 322, and the fixing screw 330 is used to abut against the electrode rod 400 to fix the position of the electrode rod 400. By tightening the forward screw 340, the position of the rear end of the electrode rod 400 abuts against the electrode holder 320 changes, thereby facilitating the adjustment of the length of the electrode rod 400 extending out of the electrode holder 320, i.e., adjusting the distance between the electrode rod 400 and the optical fiber. After adjustment, tightening the fixing screw 330 fixes the position of the electrode rod 400. If the electrode rod 400 needs to be moved backward, first loosen the fixing screw 330, then tighten the forward screw 340 to move it backward, then push the electrode rod 400 backward until it abuts against the adjusted forward screw 340, and finally tighten the fixing screw 330.

[0050] Specifically, in order to enable the insertion hole 321 to be threadedly connected to the forward screw 340 and to serve as a centering device for the electrode rod 400, the upper half of the insertion hole 321 is a threaded half-hole, and the lower half is a V-shaped groove with the opening facing upward. The electrode rod 400 is centered by abutting against the V-shaped groove, and the threaded half-hole in the upper half can be used for threaded connection of the forward screw 340.

[0051] Of course, in some other embodiments, the electrode rod 400 can be fixed in position by an electrode pressure plate.

[0052] In a further embodiment of the present invention, the base 310 is provided with a rotating hole 311, and a bearing 350 is embedded in the lower end of the rotating hole 311. The bearing 350 is mounted on the upper surface of the base 100, and the base 310 can rotate around the center of the bearing 350. Specifically, the rotating hole 311 is a through hole, and its lower end is provided with a groove 312 adapted to the outer ring of the bearing 350. The outer ring of the bearing 350 is embedded in the groove 312. The upper surface of the base 100 is provided with a second threaded hole 130 corresponding to the rotating hole 311 and the bearing 350. The inner ring of the bearing 350 is aligned with the threaded hole and threaded with a screw. The screw fixes the inner ring of the bearing 350 to the base 100, thereby realizing the rotational movement of the base 310 and reducing the rotational resistance of the bearing 350. The diameter of the rotating hole 311 and the inner ring of the bearing 350 is slightly larger than the screw thread diameter, thereby allowing for fine adjustment of the position of the base 310 on the surface of the base 100.

[0053] In a further embodiment of the present invention, a first adjusting shim is provided between the base 310 and the electrode holder 320 to adjust the height of the electrode rod 400. Specifically, the base 310 is provided with a first connecting hole 314, and the electrode holder 320 is provided with a second connecting hole 323 corresponding to the first connecting hole 314. The second connecting hole 323 is a threaded hole, and the first connecting hole 314 is a stepped through hole. The first connecting hole 314 and the second connecting hole 323 are aligned and a connecting screw is inserted through them. The connecting screw is adapted to the second connecting hole 323, and the screw head is hidden in the first connecting hole 314, thereby achieving the connection and fixation of the base 310 and the electrode holder 320. The first adjusting shim is aligned with the first connecting hole 314 and the second connecting hole 323 and allows the connecting screw to pass through. The height of the electrode rod 400 is adjusted by changing the thickness of the first adjusting shim.

[0054] Reference Figure 3 and Figure 4 In some embodiments of the present invention, the V-groove seat 200 is provided with a first through hole 230, and the upper surface of the base 100 is provided with a first mounting hole 120 corresponding to the first through hole 230. The first through hole 230 is aligned with the first mounting hole 120 and a fastener is installed thereon. The first mounting hole 120 is a threaded hole, and the fastener can be a screw adapted to the first mounting hole 120. The diameter of the first through hole 230 is larger than the screw thread diameter, thereby allowing for fine adjustment of the position of the V-groove seat 200 on the surface of the base 100.

[0055] In some embodiments of the present invention, a second adjusting shim is provided between the bottom of the V-groove seat 200 and the upper surface of the base 100. The height of the V-groove seat 200 is adjusted by adjusting the second adjusting shim, thereby adjusting the height of the optical fiber.

[0056] In some embodiments of the present invention, four sets of adjusting seats 300 and electrode rods 400 are provided and symmetrically arranged on the front and rear sides of the V-groove seat 200. This enables four-electrode arc discharge heating, increases the number of adjustable components, and widens the temperature field.

[0057] In some embodiments of the present invention, a pressure plate 700 is hinged to the rear side of the base 100. The surface of the pressure plate 700 pressing against the V-groove seat 200 is provided with two optical fiber pressing feet 710. When it is necessary to heat the optical fiber, the pressure plate 700 is rotated toward the V-groove seat 200, and the two optical fiber pressing feet 710 press the optical fiber on the V-groove 220 on the left and right sides of the heating clearance 210, thereby improving the stability of optical fiber processing.

[0058] It is understandable that, such as Figure 8 As shown, to prevent external factors from interfering with heating, a windbreak plate 800 can be installed around the base 100, and a windbreak cover 900 can be installed on the upper end of the windbreak plate 800. The windbreak plate 800 is provided with fiber optic through holes 810 for optical fibers to pass through. For easy observation, the windbreak cover 900 and the windbreak plate 800 should be made of materials with high transparency and a certain degree of hardness, such as glass.

[0059] The fiber optic heating device also includes an AC high-voltage power supply module 102 and a microscope 101 located above the heating clearance 210. The AC high-voltage power supply module 102 is connected to the electrode rod 400 via a connecting cable to provide power, and the windproof enclosure 800 is provided with a cable passage hole 820 for the connecting cable to pass through. The microscope 101 is used to observe the position of the fiber optic cable and the electrode rod 400 to facilitate position adjustment. The microscope 101 has a built-in annular reticle with crosshairs and angle scales for adjustment reference. The reticle can be made of thin quartz sheet and etched with a femtosecond laser to improve adjustment accuracy.

[0060] The control section for the electrode rod 400 switches in the AC high-voltage power supply module can be any controller capable of implementing combinations of electrode rod 400 switches. Different temperature fields can be obtained by combining the electrode rod 400 switches in different ways. To obtain the desired temperature field gradient, the frequency of the AC power supply needs to be converted. This can be achieved by adding an AC frequency conversion device, such as a frequency converter, to the AC high-voltage power supply module with logic switches.

[0061] In this invention, the height, angle, and distance from the optical fiber of the electrode rod 400 are all adjustable, as are the height of the V-groove seat 200 and the height of the optical fiber, thereby achieving multi-dimensional adjustment to provide different temperature zones for heating the optical fiber. Figure 10 The figure shown is a simulation diagram of the temperature field distribution in one embodiment.

[0062] The above description is merely a preferred embodiment of the present invention. The present invention is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effects, should be included within the scope of protection of this disclosure and fall under the protection scope of the present invention. Within the protection scope of the present invention, the technical solutions and / or implementation methods can have various modifications and variations.
