[0033] In the embodiments of the present invention, the fiber fusion splicer primarily utilizes a high-voltage arc to fuse two optical fiber sections, while simultaneously using a high-precision motion mechanism to gently advance the two fibers into a single fiber, thereby coupling the fiber mode fields. Conventional fiber fusion splicers utilize dual-electrode discharge to fuse the fibers.
[0034] However, in the process of optical fiber fusion splicing using dual-electrode discharge, due to the uneven and unstable electrode discharge, the method of using dual-electrode discharge for optical fiber fusion splicing has the problems of large fusion loss and low fusion efficiency.
[0035] Therefore, it is necessary to design a new optical fiber fusion splicer to improve the optical fiber fusion splicing efficiency and reduce the loss during the optical fiber fusion splicing process.
[0036] In order to solve the above technical problems, an embodiment of the present invention provides a fiber fusion splicer 100 , which is described in detail below.

Figure 1 As shown, the optical fiber fusion splicer 100 includes: a base 110, a laser 120, a laser external optical path structure 130, and an optical fiber adjustment structure 140;
[0038] Among them, the optical fiber adjustment structure 140 is fixedly arranged on one side of the base 110, and an optical fiber fixing component 143 is provided on the optical fiber adjustment structure 140. The optical fiber fixing component 143 is used to place and fix the optical fiber 300 to be fused. The optical fiber adjustment structure 140 is used to adjust the position of the optical fiber fixing component 143 on the base 110 so that the optical fiber 300 to be fused is located at the optical fiber coupling point 200; the light outlet of the laser external optical path structure 130 is aligned with the optical fiber coupling point 200, and the light inlet of the laser external optical path structure 130 is connected to the laser emission port of the laser 120. The laser external optical path structure 130 is used to focus the laser emitted by the laser 120 on the optical fiber coupling point 200.
[0039] In this embodiment, by aligning the light outlet of the laser external optical path structure 130 with the optical fiber coupling point 200, the light inlet of the laser external optical path structure 130 is connected to the laser emission port of the laser 120, so that the laser external optical path structure 130 can be used to focus the laser emitted by the laser 120 on the optical fiber 300 to be fused fixed at the optical fiber coupling point 200, thereby realizing rapid fusion splicing of the optical fiber, avoiding the use of the traditional dual-electrode discharge method for optical fiber fusion, thereby solving the problems of large fusion loss and low fusion efficiency caused by uneven and unstable electrode discharge, effectively improving the fiber fusion efficiency, and reducing the loss during the fiber fusion process.

[0043] The X axis, the Y axis, and the Z axis are perpendicular to each other, 360°≥θ≥−360°, and the Z axis may be the direction in which the left and right optical fibers move toward the optical fiber coupling point 200 .
[0044] Optionally, the optical fiber adjustment structure 140 provided in this embodiment is not limited to a five-axis adjustment structure, that is, it is not limited to moving only in the X-axis, Y-axis, Z-axis, and θX and θY directions, but can also move in one or more arbitrary directions. That is, the optical fiber adjustment structure 140 provided in this embodiment can also be other single-axis or multi-axis adjustment structures, which is not specifically limited here.
[0045] In the embodiment of this utility model, please continue to refer to Figure 1 The optical fiber fusion splicer 100 provided in this embodiment may further include an imaging structure 150, which is arranged corresponding to the optical fiber adjustment structure 140, and the imaging structure 150 is used to guide the optical fiber adjustment structure 140 to adjust the position of the optical fiber fixing component 143.
[0046] Specifically, the imaging structure 150 provided in this embodiment is arranged above the optical fiber adjustment structure 140, and the image acquisition lens of the imaging structure 150 is aligned with the optical fiber fixing component 143 on the optical fiber adjustment structure 140 to display the real-time collected image, so that the staff can adjust the position of the optical fiber fixing component 143 through the optical fiber adjustment structure 140 to improve the accuracy and efficiency of optical fiber fusion splicing.
[0047] As an optional embodiment, in order to further improve the accuracy and efficiency of optical fiber fusion, please continue to refer to Figure 1The imaging structure 150 provided in this embodiment may include a first imaging structure 151 and a second imaging structure 152. The first imaging structure 151 is set corresponding to the first five-axis adjustment structure 141, and the second imaging structure 152 is set corresponding to the second five-axis adjustment structure 142. The first imaging structure 151 is used to guide the first five-axis adjustment structure 141 to adjust the position of the first fixed component 1431, and the second imaging structure 152 is used to guide the second five-axis adjustment structure 142 to adjust the position of the second fixed component 1432.
[0048] By using two imaging structures 150 (a first imaging structure 151 and a second imaging structure 152), adjustment images of the first fixing component 1431 on the first five-axis adjustment structure 141 and the second fixing component 1432 on the second five-axis adjustment structure 142 are respectively collected, which can effectively improve the efficiency and accuracy of the movement of the left and right optical fibers 300 to be fused toward the fiber fusion point, thereby further improving the accuracy and fusion efficiency of the fiber fusion.
[0049] In the embodiment of the present invention, in order to ensure the accuracy and efficiency of optical fiber fusion splicing of optical fibers with different diameters, please continue to refer to Figure 1 The imaging structure 150 provided in this embodiment may also include a first imaging focus adjustment structure 153 and a second imaging focus adjustment structure 154; the first imaging focus adjustment structure 153 is used to adjust the first focal length of the first imaging structure 151, and the second imaging focus adjustment structure 154 is used to adjust the second focal length of the second imaging structure 152.
[0050] Among them, the first imaging focus adjustment structure 153 and the second imaging focus adjustment structure 154 provided in this embodiment are respectively used to adjust the height of the first imaging structure 151 and the second imaging structure 152, so as to adjust the focal length of the first imaging structure 151 and the second imaging structure 152, so as to achieve the purpose of clear imaging of optical fibers of different diameters, so that when optical fibers of different diameters are welded, the accuracy and efficiency of optical fiber welding can be effectively guaranteed.
[0051] In the embodiment of the present invention, in order to further improve the accuracy and efficiency of optical fiber fusion, please continue to refer to Figure 1 The imaging structure 150 provided in this embodiment may further include an imaging alignment adjustment structure 155, which is arranged on the first imaging focus adjustment structure 153 or the second imaging focus adjustment structure 154. The imaging alignment adjustment structure 155 is used to adjust the image center of one of the connected imaging structures 150 to be consistent with the image center of the other imaging structure 150.
[0052] In this way, the imaging alignment adjustment structure 155 can be used to adjust the image centers of the first imaging structure 151 and the second imaging structure 152 to be consistent, thereby effectively ensuring the accuracy and efficiency of optical fiber fusion splicing.
[0053] As an optional embodiment, a shock-absorbing pad 111 may be provided under the base 110 provided in this embodiment. The shock-absorbing pad 111 can effectively prevent the vibration generated by the table on which the optical fiber fusion splicer 100 is placed from being transmitted to the optical fiber fusion splicer 100, thereby affecting the optical fiber coupling alignment.
[0054] In some embodiments, also to improve fiber fusion efficiency, the laser 120 provided in this embodiment can be a carbon dioxide laser. A carbon dioxide laser is a gas laser that uses CO2 gas as its working medium. The discharge tube is typically made of glass or quartz and filled with CO2 and other auxiliary gases (primarily helium and nitrogen, and often a small amount of hydrogen or xenon). The electrodes are typically hollow nickel cylinders. One end of the resonant cavity is a gold-plated full-reflection mirror, and the other end is a partial-reflection mirror ground from germanium or gallium arsenide. When a high voltage (typically direct current or low-frequency alternating current) is applied to the electrodes, a glow discharge is generated in the discharge tube, and laser output is emitted from one end of the germanium mirror.
[0055] In other embodiments, to protect the optical fiber fusion splicing process, the optical fiber fusion splicer 100 provided in this embodiment may further include a protective cover (not shown in the figure), which may be disposed at the outermost periphery of the optical fiber fusion splicer 100. In this way, by covering the outermost periphery of the optical fiber fusion splicer 100 with the protective cover, it can play a sealing and protective role during optical fiber fusion splicing, thereby protecting the optical fiber fusion splicing process and effectively improving the optical fiber fusion splicing efficiency.
[0056] In summary, an embodiment of the present invention provides a fiber fusion splicer, comprising a base, a laser, a laser external optical path structure, and a fiber adjustment structure. The fiber adjustment structure is fixedly arranged on one side of the base. A fiber fixing assembly is provided on the fiber adjustment structure. The fiber fixing assembly is used to place and fix the optical fiber to be fused.
