Description

Technical Field

[0001] The utility model relates to the field of optical fiber cutting, in particular to a staggered electric cutter device and a welding machine thereof. Background Art

[0002] In the field of optical fiber communication, optical fiber cleavers are one of the indispensable tools in the process of optical fiber connection and maintenance. Traditional optical fiber cleavers are usually designed with the rotating surface of the cover parallel to the moving direction of the cleaver. Although this design can achieve effective optical fiber cutting, it also brings some significant problems.

[0003] First, due to the design that the rotating surface of the gland is parallel to the moving direction of the cutter, a large space needs to be reserved inside the equipment to accommodate the gland. This not only leads to an increase in the overall volume of the welding machine, but also makes the equipment take up more space during the integration process. This design is large in size, which is not conducive to carrying and on-site operation, especially in application scenarios where space is limited or frequent movement is required. Secondly, the larger structural design directly leads to an increase in manufacturing costs. The larger volume requires more materials and more complex manufacturing processes, which increases production costs. Utility Model Content

[0051] Furthermore, the cover plate 4 is arranged on the opposite side of the optical fiber clamping part 2, and one end of the cover plate 4 is hinged to the body 1, so that the cover plate 4 can rotate relative to the body 1, and the movement trajectory of the cover plate 4 forms an arc surface, and the cutting part 3 is provided with an electric cutter 31, the electric cutter 31 can perform linear motion on the body 1 (that is, the movement trajectory of the electric cutter 31 is a straight line), the straight line formed by the movement trajectory of the electric cutter 31 is perpendicular to the arc surface formed by the movement trajectory of the cover plate 4, the movement trajectory of the electric cutter 31 is set to be perpendicular to the movement trajectory of the cover plate 4, and the movement trajectory of the electric cutter 31 is perpendicular to the axial direction of the optical fiber 21. When the optical fiber 21 is cut, its axial direction is parallel to the width direction of the fusion splicer. In this way, the cover plate 4 is opened from the side to avoid the situation that the rotating surface of the cover plate 4 is parallel to the moving direction of the electric cutter 31, resulting in the electric cutter device occupying too much space when in use;

[0052] Furthermore, a transmission part 13 is provided on the body 1, and the transmission part 13 includes a transmission shaft 131. The body 1 is connected to the cutting part 3 through the transmission shaft 131, and a rotating shaft 16 is also provided on the body 1.

[0054] Furthermore, a pawl 12 is provided on the body 1, and the pawl 12 is arranged on the displacement path of the cutting part 3. The cutting part 3 is provided with an electric cutter 31 and a ratchet 32 ​​rigidly connected to the electric cutter 31. The ratchet 32 ​​is configured to be matched with the pawl 12.

At this time, the pawl 12 cooperates with the ratchet 32 ​​to drive the ratchet 32 ​​to rotate. At the same time, since the ratchet 32 ​​is rigidly connected to the electric cutter 31, when the ratchet 32 ​​rotates, it drives the electric cutter 31 to rotate, thereby completing the surface change of the electric cutter 31.

[0055] In an optional embodiment, a transmission part 13 is provided on the body 1, and the transmission part 13 can ensure that the driving device 11 controls the cutting part 3, and a rack is provided at one end of the transmission part 13 connected to the driving device 11, and the driving device 11 is provided with an output part 111, and the output part 111 is engaged with the rack, thereby driving the entire transmission part 13 to move;

[0059] This embodiment is a fusion splicer, where a staggered electric cutter device is installed on the fusion splicer, specifically near a side line of the fusion splicer, and the long side of the device is parallel to the side line of the fusion splicer. The staggered electric cutter device is installed near the side line of the fusion splicer, and its long side is parallel to the side line, which effectively utilizes the space of the fusion splicer. Such a layout reduces the occupation of the rest of the area of ​​the fusion splicer, making the overall structure more compact. A control device 5 is provided on the fusion splicer, and the control device 5 is connected in communication with the drive device 11, so that the control device 5 can be used to control the cutting part 3.
