Description

Technical Field

[0001] This utility model belongs to the field of optical fiber fusion splicing technology, specifically relating to a vertical electrode quartz rod fusion splicer. Background Technology

[0002] Fiber optic and quartz rod fusion splicing is a process in which optical fibers and / or quartz rods are placed on a fusion splicer and brought to a molten state for butt joint connection. Existing fusion splicer equipment is all horizontal, splicing the fiber and quartz rod horizontally. However, during high-temperature fusion splicing, due to gravity, the molten quartz rod's splice point will sag radially, causing a radial offset in the splice point position and affecting the beam output quality of the quartz rod. Especially in the production of high-power fiber optic devices, the existing horizontal fusion splicing method is insufficient to meet the quality requirements of high-power fiber optic devices. Utility Model Content

[0022] Due to the adoption of the above technical solution, this utility model has the following advantages and effects:

[0023] (1) The present invention provides a vertical electrode quartz rod fusion splicer. The fusion splicer is designed as a vertical layout. The optical fiber and the quartz rod are vertically clamped and moved up and down to fused. In the molten state, since the quartz rod is vertically upward, the direction of gravity is perpendicular to the radial direction of the fusion point. This effectively avoids the radial displacement of the fusion point caused by gravity in the molten state, so that the core and cladding of the fused quartz rod can maintain better concentricity, thereby improving the stability and quality of beam transmission.

[0024] (2) The vertical electrode quartz rod welding machine provided by this utility model avoids the stress concentration that easily occurs near the welding point during horizontal welding due to the weight of the quartz rod itself and possible external forces, which would affect the transmission characteristics of the beam. Vertical welding can reduce this stress concentration, making the stress distribution of the quartz rod during the welding process more uniform, reducing stress concentration, and making the internal structure of the quartz rod after welding more stable, which is conducive to the high-quality output of the beam.

[0025] (3) The vertical electrode quartz rod welding machine provided by this utility model can optimize the arc welding temperature field. Vertical welding helps to form a more uniform arc welding temperature field. In horizontal welding, heat may be unevenly distributed in the welding area due to factors such as gravity or thermal convection, resulting in uneven glass state at the welding point, which in turn affects the beam quality. When vertical welding is performed, the heat conduction in the horizontal radial direction is relatively more uniform, which can make the glass state at the welding point more uniform and consistent, reduce the difference in optical performance caused by temperature unevenness, and thus improve the beam quality.

The Z-axis power main body assembly 25 drives the upper optical fiber clamping motion assembly 21 and the mid-section electrode heating motion assembly 22 to move up and down, so that the ends of the optical fiber and the ends of the quartz rod are vertically aligned at the center of the electric arc's temperature field and fused together by the electric arc.

[0039] Before fusion splicing, the Z-axis power main body assembly 25 first drives the upper fiber clamping motion assembly 21 and the middle electrode heating motion assembly 22 to move so that the lower end of the fiber is aligned with the temperature field center of the electric arc. Then, the lower quartz rod clamping motion assembly 23 drives the quartz rod to move so that the upper end of the quartz rod is aligned with the lower end of the fiber and fused through the electric arc.

The Y-axis camera adjustment platform 246 is located at the rear end of the Z-axis support frame 2517. Z-axis fixing blocks 2516 are provided on both sides of the lower end of the Z-axis support frame 2517. These blocks are embedded and fixed within the power main component mounting slot 273, achieving a vertical fixed connection between the Z-axis support frame 2517 and the main unit base 27. A pair of linear guide rails 2515 are vertically positioned on the front end face of the H-shaped bracket, opposite to the lower quartz rod clamping motion component 23. A pair of upper platform drive sliders 255 are horizontally spaced opposite each other, and a pair of middle platform drive sliders 2512 are horizontally spaced opposite each other.

[0063] like Figure 9 As shown. Furthermore, the welding host 2 also includes an external protective cover 26, which includes a bottom housing 261, an upper protective housing 262, and an upper movable cover 263.

The upper protective housing 262 is disposed on the bottom housing 261 and wraps around the rear periphery of the Z-axis power main body assembly 25. The upper movable cover 263 is hinged to the upper end of the upper protective housing 262 and wraps around the front periphery of the Z-axis power main body assembly 25.

[0064] Specifically, the bottom housing 261 is fixed to the main unit base 27 and encloses the camera light source assembly 24. The bottom housing 261 has an opening in the middle, and one side of the opening is connected to and fixed to the lower end of the upper protective housing 262. The upper end of the upper movable cover 263 is hinged to the upper frame of the upper protective housing 262 via piano hinges. The upper movable cover 263 can be flipped open and closed to provide wind protection and light shielding, thereby protecting the normal operation of the fusion splicing host. After the upper movable cover 263 is fastened, the Z-axis power main body assembly 25, the upper fiber optic clamping motion assembly 21, the middle electrode heating motion assembly 22, the lower quartz rod clamping motion assembly 23, and the camera light source assembly 24 are all located inside the outer protective cover 26.

[0065] This utility model discloses a vertical electrode quartz rod fusion splicing machine. The motion layout is vertical, with an optical fiber at the upper end and a quartz rod at the lower end. The optical fiber is mounted on the optical fiber adsorption fixture of the upper optical fiber clamping motion component by vacuum adsorption and clamping. The optical fiber adsorption fixture has a Z-axis layout, with the downward-extending end of the optical fiber (fusion end) hanging down naturally. The quartz rod is adsorbed and fixed on the quartz rod vacuum adsorption fixture of the lower quartz rod clamping motion component. Between the optical fiber and the quartz rod is a middle section electrode heating motion component. The lower end of the extended optical fiber and the end face of the lower quartz rod to be fused are automatically aligned and fused at the center of the three electrodes of the middle section electrode heating motion component.

[0066] During automatic alignment, the optical fiber is first aligned with the center of the arc temperature field at the front end of the three electrodes to ensure that the Z-axis of the optical fiber is coaxial with the array center of the three electrodes. Then, the optical fiber remains stationary, and the quartz rod is automatically aligned with the optical fiber by clamping the motion component at the lower end of the quartz rod in conjunction with the camera light source component and through the image algorithm.

[0067] This invention transforms the undesirable factor of radial drooping of the quartz rod during the original horizontal fusion splicing into an advantageous factor, ensuring that the fusion point between the optical fiber and the quartz rod always maintains axial drooping and stacking along the Z-axis in the molten state. This not only directly eliminates the problem of radial drooping of the fusion point caused by horizontal fusion splicing in horizontal fusion splicing machines, but also results in high beam quality output from the quartz rod after fusion splicing.

[0068] 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.
