Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of optical fiber cutting, and specifically relates to a sliding type optical fiber jumper pre-cutting device. Background Art
[0002] In the current rapid development of digital information, optical fiber communication technology has become a key support for information transmission. With the continuous expansion of 5G and cloud computing data centers, and the research and development progress of 6G communication technology, the demand for high-speed, large-capacity, and low-loss optical fiber communication systems has increased sharply. As a core component of the optical fiber communication system, the performance of single-mode optical fiber jumpers directly affects the quality of communication links.
[0003] In actual production and manufacturing, although optical fiber manufacturing technology has made progress and can produce high-precision single-mode optical fibers, there are technical bottlenecks in the jumper cutting link. Manual cutting uses scissors, with low efficiency and it is difficult to ensure standardization. Traditional mechanical cutting is to use a diamond blade to scratch the surface of the optical fiber and then make it break. The operation is simple and the cost is low, but it is difficult to control the force and angle, which easily causes uneven end faces and poor length accuracy, increasing signal loss and reflection; flame cutting is to use a high-temperature flame to fuse the optical fiber. Although it can ensure the integrity of the cross-section, the thermal stress affects the optical performance and the cutting length error is large. None of them can meet the high-precision requirements. Existing automated equipment lacks flexibility and precision when facing diverse production demands and cannot meet personalized orders. In addition, large-scale industrial production requires cost reduction and efficiency improvement. The existing cutting technologies have low material utilization rate and long production cycles, and are difficult to adapt to market competition. Summary of the Invention

[0021] As a preferred embodiment of the present invention, as Figure 2 shown, the cutter assembly (8) includes a cutter groove top cover (801), a sliding cutter groove (802), a moving blade (803), and a fixed blade (804). The fixed blade (804) is installed in the sliding cutter groove (802), and the cutter groove top cover (801) is installed on the top of the sliding cutter groove (802); the lower surface of the moving blade (803) contacts the upper surface of the fixed blade (804); the upper surface of the moving blade (803) contacts the inner side of the cutter groove top cover (801), so that the moving blade (803) can slide in the space formed by the sliding cutter groove (802), the cutter groove top cover (801), and the fixed blade (804).
[0022] The pre-cutting device of the present invention adopts a blade sliding type cutting technology. As Figure 2 shown, during the cutting process, first, the holding claw assemblies (3) at the top and bottom of the cutter assembly (8) clamp the optical fiber cable. The slide cylinder (5) is connected to one side of the moving blade (803) through a floating connection to transmit power to the moving blade (803), so that the moving blade (803) moves in the fixed space formed by the sliding cutter groove (802), the cutter groove top cover (801), and the moving blade (803) to complete the cutting.
[0023] As a specific embodiment of the present invention, the moving blade (803) and the fixed blade (804) are provided with 90-degree notches on the cutting side, and the non-opening sides always hold and overlap; the sliding knife groove (802) and the knife groove top cover (801) are correspondingly opened at the cutting position. An opening is made on the side of the moving blade (803) away from the cutting edge, and the size of the opening is slightly larger than the diameter of the pin shaft (10), so that the pin shaft (10) and the moving blade (803) are kept in a floating connection to eliminate the phenomenon of over-positioning and jamming.

[0025] As a specific embodiment of the present invention, the holding jaw assembly (3) is adopted in a detachable manner, and different jaw heads (302) are replaced according to different diameters of the cable. The jaw head (302) is made of a flexible material, the opening is an obtuse angle, the left and right jaws are layered and partially overlap each other, providing a larger jaw opening, which is beneficial to accurately clamping the cable; the holding jaw assembly (3) is distributed directly above and below the cutting position, and provides a tensioning force for the cable through the jaws, ensuring that the cable is perpendicular to the blade. Providing a certain tensioning force helps to improve the cutting accuracy.
[0026] The following combines Figure 2 with Figure 4 to describe the working process of the present invention.
[0027] As Figure 4 shown, in the preparation stage, the slide table cylinder (5) and the pneumatic finger (1) are opened. After the cable enters the cutting area vertically, the upper and lower jaw assemblies (3) are closed first. After the cable is stable, the slide table cylinder (5) drives the cutting assembly (8) to cut. During the cutting process, first, the holding jaw assemblies (3) at the top and bottom of the cutting tool assembly (8) clamp the optical fiber cable. The slide table cylinder (5) is connected to one side of the moving blade (803) through a floating connection to transmit power to the moving blade (803), so that the moving blade (803) moves within the fixed space formed by the sliding knife groove (802), the knife groove top cover (801), and the moving blade (803) to complete the cutting.
[0028] As Figure 2As shown, between the blades, it is necessary to make the end face of the blade flush with the end face of the tool by means of surface grinding and matching of the sliding tool groove (802) and the tool groove top cover (801), so as to minimize the cutting gap between the blades. The smaller the cutting gap of the blade, the higher the cutting accuracy of the cable, which is beneficial to subsequent jumper processing. And one side of the blade is provided with a notch, and the shape of the notch is a right angle. The notch is beneficial to the stability of the cable during the cutting process without slipping, ensuring a flat cut. At the same time, openings need to be made at the corresponding positions of the sliding tool groove (802) and the tool groove top cover (801) to provide a cutting space.
[0029] The above description of the present invention and its implementation manners is not intended to limit the present invention. For those skilled in the art, any design, modification, replacement, etc. made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
