Description

Technical Field

[0001] The invention relates to the field of optical fiber communication, and in particular to an adaptive mechanism used on an automatic optical fiber thermal stripping machine. Background Art

[0002] A heat stripping machine is a device used for optical fiber processing. Its main function is to remove the coating layer on the surface of the optical fiber by heating so as to carry out subsequent optical fiber connection, fusion splicing and other operations. In the fields of optical fiber communication and optical fiber sensing, a heat stripping machine is one of the indispensable tools. The working principle of a heat stripping machine is usually to soften the optical fiber coating by high temperature heating, and then to strip the coating layer mechanically. Specifically, the heating element inside the heat stripping machine will heat the optical fiber to a certain temperature, making the coating layer soft, and then strip the coating layer from the surface of the optical fiber by tools such as clamps or cutters. The heat stripping machine is widely used in optical fiber processing. During the optical fiber connection process, the coating layer of the optical fiber needs to be removed so that the core wires of the optical fiber can be aligned and fusion spliced. During the optical fiber fusion splicing process, the heat stripping machine can help remove the optical fiber coating layer so that the optical fiber core wires can be better fusion spliced ​​together. In optical fiber sensing applications, the heat stripping machine can be used to prepare the probe part of the optical fiber sensor and remove the coating layer to facilitate the coupling of external signals.

[0003] However, the existing hot stripping machines often encounter the following problems during use:

[0004] (1) In the working scene of the traditional optical fiber thermal stripping machine, there are considerable safety hazards due to the limitations of its structural design. When the optical fiber thermal stripping machine performs operations such as stripping the coating layer on the optical fiber, it is necessary to fix and position the optical fiber through components such as clamps. However, these clamps are often opened and clamped according to a fixed procedure and lack the ability to perceive the surrounding environment. For example, when the operator places the optical fiber into the thermal stripping machine or adjusts the equipment during operation, it is easy to accidentally put the finger close to the operating clamp part. At this time, the clamp does not recognize the difference between the finger and the optical fiber. Once the clamping action is started, it will clamp the finger with a greater force. This clamping force is usually set to ensure the stability of the optical fiber during operation. For the soft fingers of the human body, it often causes serious pinching injuries, such as bruises, fractures, or even more serious injuries.

[0005] (2) There are various models and structural types of optical fiber thermal stripping machines on the market. Different manufacturers will design optical fiber thermal stripping machines with great differences based on their own technical concepts, production processes, cost control and other factors. For example, some optical fiber thermal stripping machines use a vertical clamp structure, while others are horizontal; some devices are driven by electricity, while others are pneumatic. This structural diversity makes it a huge challenge to uniformly equip them with safety protection and efficient optical fiber processing structures. From the perspective of safety protection, an anti-pinch device suitable for a vertical clamp structure cannot be directly applied to a thermal stripping machine with a horizontal clamp structure. Because of the differences in their spatial layout, movement mode, etc., this structural difference makes it difficult to develop a universal safety protection and efficient optical fiber processing structure that can simultaneously meet the needs of different optical fiber thermal stripping machines, increasing the R&D cost of the entire industry and the difficulty of equipment upgrades.

[0006] (3) Due to its small size, optical fibers often become tangled and warped during the preparation for laying and the early placement in equipment (such as optical fiber thermal stripping machines). During the storage or transportation of optical fibers, even a slight shake or external force interference may cause the optical fibers to become tangled. Once the optical fibers are tangled together, it is very difficult to untangle them, which requires a lot of time and effort. Summary of the invention

[0007] The main purpose of the present invention is to provide an adaptive mechanism for an automatic optical fiber thermal stripping machine, which at least solves one of the above problems to a certain extent.

[0008] To achieve the above object, the technical solution adopted by the present invention is:

[0009] An adaptive mechanism for an automatic optical fiber thermal stripping machine, comprising:

[0010] Base;

[0011] A guide rail, the guide rail being laid transversely on the base;

[0017] A clamping groove, the clamping groove is provided on one side of the optical fiber clamp;

[0018] A fiber pressing cover, the fiber pressing cover is hinged to one side of the optical fiber clamp;

[0019] A clamping plate, the clamping plate being hinged to one end of the fiber pressing cover;

[0020] A fixing block is located in an extending direction of one side of the optical fiber clamp.

[0021] The adaptive mechanism further comprises:

[0022] displacement grooves, at least two of which are arranged side by side at the bottom of the optical fiber clamp;

[0023] A limit block, which is fixedly arranged on the integrated sliding platform and embedded in the displacement groove;

These parts can be laid, improve the efficiency of the early optical fiber preparation work, and facilitate accurate optical fiber coating stripping and other operations.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "configuration", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0051] like Figure 1-3 As shown, an adaptive mechanism for an automatic optical fiber thermal stripping machine includes: a base 1, a guide rail 2, an integrated sliding platform 3, an optical fiber clamp 4, an adaptive mechanism 5, a slide rail 6, an optical fiber slot 7, a snap-in slot 8, a fiber pressing cover 9, and a snap-in plate 10; the guide rail 2 is laid horizontally on the base 1, the integrated sliding platform 3 is slidably connected to the guide rail 2, and the integrated sliding platform 3 will slide linearly along the guide rail 2. The optical fiber clamp 4 is located above the integrated sliding platform 3, the slide rail 6 is installed on the top surface of the integrated sliding platform 3, and the slide rail 6 is slidably connected to the integrated sliding platform 3. In actual working scenarios, the smoothness and accuracy of this sliding are very important because it is directly related to the accuracy of subsequent optical fiber operations. The integrated sliding platform 3 is like a train carriage running on a track, which can move stably on the guide rail 2 and carry other important components to work together.

[0052] Preferably, the optical fiber clamp 4 will slide along the guide of the slide rail 6. The optical fiber card slot 7 is provided on the top surface of the optical fiber clamp 4, and the clamping slot 8 is provided on one side of the optical fiber clamp 4. The shape and size of the card slot are designed according to the characteristics of the optical fiber to ensure that the optical fiber can be stably placed therein and will not be easily displaced. The fiber compression cover 9 is hinged to one side of the optical fiber clamp 4, and the clamping plate 10 is hinged to one end of the fiber compression cover 9. The clamping plate 10 is made of metal, and the fixing block 11 is located in the extension direction of one side of the optical fiber clamp 4. When the optical fibers are placed side by side in the optical fiber card slot 7, the fiber compression cover 9 will press on the optical fiber card slot 7 to fix and limit it, ensuring that it will not fall off due to the movement of the optical fiber clamp 4.

[0053] In this embodiment, in order to prevent the displacement of the optical fiber clamp 4 from clamping to the bottom, an adaptive mechanism 5 is provided, including: at least two displacement grooves 51 are arranged side by side at the bottom of the optical fiber clamp 4, a limit block 52 is fixedly provided on the integrated sliding platform 3, and the limit block 52 is embedded in the displacement groove 51, the limit block 52 is slidably connected to the displacement groove 51, one end of the spring 53 is connected to the limit block 52, and the other end of the spring 53 is connected to the inner wall of the displacement groove 51. The setting of the spring 53 provides a rebound condition for the optical fiber clamp 4, and the setting of the displacement groove 51 ensures that the spring 53 will not bend when being squeezed. The optical fiber clamp 4 that can rebound adds an adaptive function to the heat stripping machine. In a high-speed factory, once a worker accidentally puts his hand or other foreign objects between the optical fiber clamp 4 and the fixed block 11, the optical fiber clamp 4 will move toward the fixed block 11. The optical fiber clamp 4 will reduce the clamping force due to the setting of the reset spring 53. At the same time, it will be pushed in the opposite direction by the obstacle due to the squeezing of the spring 53, and will not cause damage to the obstacle. Although the method is simple, it has a wide range of applications. It can be installed in optical fiber heat stripping machines of any form and is easy to mass produce.

[0054] Preferably, the first card slot 12 is provided on the bottom surface of the integrated sliding platform 3, and the guide rail 2 is embedded in the first card slot 12, the second card slot 13 is provided on the bottom surface of the optical fiber clamp 4, and the slide rail 6 is embedded in the second card slot 13, and the arrangement of the card slot and the slide rail 6 can ensure the stability of the integrated sliding platform 3 and the optical fiber clamp 4, so that the side-by-side optical fibers remain flat when they are displaced. The pressure cover card slot 14 is provided on the fiber pressing cover 9, and the pressure cover card slot 14 extends all the way to the extension plate 16, and the lower pressing plate 15 is clamped inside the pressure cover card slot 14. After being pressed down, the lower pressing plate 15 will press on the side-by-side optical fibers to prevent the optical fibers from warping and ensure that each optical fiber is flush. The extension plate 16 is connected to one side of the fiber pressing cover 9, and the oblique slope 17 is provided at the top edge of the clamping slot 8, and the magnet 18 is arranged in the clamping slot 8. The oblique slope 17 can provide buffer and guidance for the connection between the clamping plate 10 and the clamping groove 8, making each opening and closing extremely convenient and reducing the wear of the clamping plate 10 during clamping. The boosting groove 19 is opened on the top surface of the optical fiber clamp 4, and the boosting groove 19 is connected to the clamping groove 8. The roller piece 20 is movably installed inside the boosting groove 19. The roller piece 20 is annular. When the side-by-side optical fibers are initially placed in the optical fiber clamping groove 7, they will be relatively messy. The rolling of the roller piece 20 will help the edge optical fibers to facilitate their adjustment. After the fiber pressing cover 9 is pressed down, it will press the roller piece 20 so that it cannot roll.

[0055] It should be noted that the adaptive mechanism designed by the present invention for an automatic optical fiber thermal stripping machine, when in use, the optical fiber is placed in the optical fiber card slot 7, covered with a fiber pressing cover 9, and the clamping plate 10 will be adsorbed on the magnet 18 in the clamping slot 8 for fixation. When the base 1 drives the integrated sliding platform 3 to move toward the fixed block 11, the optical fiber clamp 4 will simultaneously move toward the fixed block 11. If there is no obstacle between the optical fiber clamp 4 and the fixed block 11, as the integrated sliding platform 3 moves, the right end of the optical fiber clamp 4 will eventually contact the left end of the fixed block 11. At this time, if the structure is installed on the automatic thermal stripping machine, the thermal stripping device can be started to fix one end of the optical fiber, and then the integrated sliding platform 3 can be controlled to move away from the fixed block 11 to strip the coating layer at one end of the optical fiber. However, when there is an obstacle between the optical fiber clamp 4 and the fixed block 11, as the integrated sliding platform 3 moves, the optical fiber clamp 4 will first contact the obstacle, and then move toward the fixed block 11 together with the obstacle, until the obstacle contacts the fixed block 11 to generate a resistance force, and the integrated sliding platform 3 continues to move toward the fixed block 11 in the original direction. At this time, due to the obstruction of the obstacle, the optical fiber clamp 4 cannot continue to move toward the fixed block 11, and the spring 53 inside the optical fiber clamp 4 begins to be squeezed by the obstacle and moves in the opposite direction of the fixed block 11, thus avoiding the obstacle from being squeezed and damaged. When the integrated sliding platform 3 moves away from the fixed block 11 again, the optical fiber clamp 4 will also move away together, the squeezing of the spring 53 disappears, the spring 53 rebounds, and the optical fiber clamp 4 is reset. In this way, it can be reused.

[0056] Although embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations may be made to these embodiments without departing from the principles and spirit of the invention, and the scope of the invention is defined by the appended claims and their equivalents.
