Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber winding, in particular to a glue brushing device used for winding optical fiber ring tape glue. Background Art

[0002] A fiber-optic gyroscope (FOG), also known as a fiber-optic angular velocity sensor or ring interferometer, is an innovative optical gyroscope based on optical fiber technology and the Sagnac effect. It is used to accurately measure the angular velocity or rotation angle of an object in inertial space. This gyroscope is unique in its zero-rotating mass design, specifically its lack of a high-speed rotor, earning it the name solid-state gyroscope. FOGs have broad application prospects in a variety of cutting-edge fields, including aerospace, navigation, and inertial measurement.

[0003] In fiber optic gyroscopes and fiber optic sensing applications, fiber optic rings are key optically sensitive components, and their manufacturing process is crucial for ensuring the performance and precision of fiber optic gyroscopes. Fiber optic ring production typically involves key steps such as fiber winding, ring impregnation, and curing. The choice and implementation of the ring impregnation process directly impact the final quality of the fiber optic ring. Depending on the timing of ring gluing, two main fiber optic ring winding methods exist: dipped-in-glue winding and tape-in-glue winding. The dipped-in-glue winding method first winds the fiber optic ring and then fills the ring with glue through a specialized process. While a mature process, this method suffers from long production cycles, high material consumption, and difficulty in precisely controlling the glue distribution. In contrast, the tape-in-glue winding method, in which the fiber is first coated with glue before winding, offers significant advantages, such as simplified production processes, shorter production cycles, and material savings. Products using this method even outperform dipped-in-glue winding in certain performance aspects. However, the current tape-in-glue winding method still faces several technical challenges in its implementation. First, the fluidity and viscosity of glue are extremely sensitive to temperature. Improper temperatures can lead to excessively high viscosity or poor fluidity, which in turn affects the glue application and the quality of the fiber optic ring. Second, precisely controlling the amount of glue applied is crucial for achieving high-quality fiber optic rings. However, existing devices often struggle to achieve this precise control, resulting in uneven glue distribution or waste within the ring. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the existing technology, and its main purpose is to provide a glue brushing device for optical fiber ring tape winding, which solves the technical problems of improper glue temperature control in the existing tape winding method, affecting the fluidity and viscosity of the glue, and uneven glue distribution during the glue brushing process, which ultimately leads to poor quality of optical fiber ring products, glue waste, and increased costs.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a glue brushing device for winding an optical fiber ring belt glue, comprising:

[0007] Glue brushing device body;

[0008] A glue dispensing syringe is mounted on the main body of the glue-brushing device and is used to store and quantitatively output glue. A glue-brushing groove and a fiber-guiding groove passing through the glue-brushing groove are provided on the side of the main body of the glue-brushing device away from the glue-brushing syringe. The fiber-guiding groove is used to pass optical fibers. The glue-dispensing end of the glue-dispensing syringe is arranged directly above the glue-brushing groove. The glue-brushing groove is used to receive the glue output by the glue-dispensing syringe.

[0009] A heating element is provided beside the glue discharging syringe and installed on the main body of the glue brushing device, and is used to heat the main body of the glue brushing device;

[0010] A temperature probe is mounted on the main body of the glue brushing device and is used to monitor and transmit the heat conduction temperature of the main body of the glue brushing device;

[0011] A pneumatic device is provided on the side of the main body of the glue brushing device and is used to control the glue output of the glue dispensing syringe;

[0012] The control unit is electrically connected to the heating element, the temperature probe and the pneumatic device.

[0013] As a preferred solution, the glue dispensing syringe includes a cylinder, a pneumatic push rod and a glue dispensing needle. The main body of the glue brushing device is provided with a mounting groove adapted to the cylinder. The cylinder is installed on the mounting groove and is fixedly connected to the main body of the glue brushing device by a set screw. The pneumatic push rod is installed on the cylinder. The glue is stored in the cylinder. The pneumatic push rod is used to extrude the glue stored in the cylinder. The transmission end of the pneumatic device is connected to the pneumatic push rod. The glue dispensing needle is installed at one end of the cylinder close to the fiber groove and is located directly above the glue brushing groove.

[0014] As a preferred solution, the fiber routing groove passes through the middle of the glue brushing groove, the glue discharge needle is in the shape of an elbow, the glue outlet of the glue discharge needle points vertically downward to the center of the glue brushing groove, and a threaded fixing hole adapted to the set screw is provided on one side of the glue brushing device body.

[0015] As a preferred solution, the fiber-guiding trough is further provided with inclined guide surfaces on two opposite sides of one end close to the glue-discharging needle.

[0016] As a preferred solution, a mounting through hole adapted to the heating element is provided on the main body of the glue brushing device, the mounting through hole passes through the main body of the glue brushing device, and the temperature probe is installed on the side of the main body of the glue brushing device away from the fiber trough.

[0017] As a preferred solution, the depth of the glue brushing groove is greater than the depth of the fiber running groove.

[0018] As a preferred solution, the liquid level of the glue in the glue brushing groove is not higher than 0.5 mm from the bottom of the fiber trough, and the height of the glue submerged above the optical fiber is 0.1 to 0.2 mm.

[0019] As a preferred solution, the width of the fiber trough is no more than 0.25 mm.

[0020] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it mainly provides constant temperature conditions for the entire glue brushing device by introducing a heating element and a temperature probe to ensure that the fluidity and viscosity of the glue are moderate. At the same time, the use of a pneumatic device and a control unit can realize the precise adjustment of the glue output of the glue syringe. Combined with the glue brushing groove and the fiber duct groove, it ensures that the optical fiber can be evenly coated with glue when passing through, and avoids the formation of an excessively thick glue layer on the surface of the optical fiber due to excessive glue, which affects the subsequent production process, reduces the loss and waste of glue, and reduces costs.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0034] See also Figures 1 to 4 The present invention provides a glue brushing device for winding an optical fiber ring belt adhesive, comprising:

[0035] The glue brushing device body 10 serves as the basic supporting structure of the entire device, ensuring that all components are firmly installed and work in coordination.

[0036] The glue dispensing syringe 20 is mounted on the glue dispensing device body 10 and is used to store and quantitatively dispense glue. It cooperates with a pneumatic device to ensure the appropriate amount of glue is used during the fiber optic ring tape adhesive winding process. A glue dispensing groove 11 and a fiber routing groove 12 extending through the glue dispensing groove 11 are provided on the side of the glue dispensing device body 10 away from the glue dispensing syringe 20. The fiber routing groove 12 is used to thread the optical fiber 30. The dispensing end of the glue dispensing syringe 20 is positioned directly above the glue dispensing groove 11, ensuring that the glue falls directly and evenly into the glue dispensing groove 11. The glue dispensing groove 11 is used to receive the glue dispensed by the glue dispensing syringe 20.

[0037] The heating element 40 is arranged beside the glue dispensing syringe 20 and installed on the glue brushing device body 10, and is used to heat the glue brushing device body 10, provide a constant temperature condition for the entire device, ensure the fluidity and viscosity of the glue, and promote the uniform distribution of the glue on the surface of the optical fiber 30.

[0038] The temperature probe 50 is installed on the main body 10 of the glue brushing device and is used to monitor and transmit the heat conduction temperature of the main body 10 of the glue brushing device in real time, so as to know the temperature of the glue and ensure that the heating process is carried out within a safe and stable temperature range, thereby ensuring that the fluidity and viscosity of the glue are moderate, while avoiding damage to production materials or equipment, and providing a data basis for the regulation of the heating element 40, so that the entire device can be continuously in a stable constant temperature environment.

[0039] The pneumatic device is arranged beside the glue brushing device body 10 and is used to control the glue output of the glue dispensing syringe 20 to ensure the continuity and accuracy of the glue output.

[0040] The control unit is the core of the entire device. The heater 40, temperature probe 50, and pneumatic device are all electrically connected to the control unit, enabling precise control of heating temperature and adhesive output, ensuring efficient, stable, and high-quality fiber optic tape adhesive winding. The temperature probe 50 transmits heat conduction temperature information to the control unit, allowing manual operation to adjust the heating temperature of the heater 40.

[0041] It should be noted that the heating element 40 is preheated first, and the entire device is preheated by heat transfer, and monitored by the temperature probe 50. After the temperature of the entire device reaches the process requirements and stabilizes, the optical fiber 30 is brushed with glue, and then the optical fiber ring is wound on the optical fiber 30 that has been brushed with a layer of glue.

[0042] In a preferred embodiment, the heating element 40 is a heating rod.

[0043] In this embodiment, the glue dispensing syringe 20 serves as the core component for glue output, and includes a barrel 21, a pneumatic push rod 22, and a glue dispensing needle 23. The main body 10 of the glue brushing device is provided with a mounting groove 14 that is compatible with the barrel 21. The barrel 21 is mounted on the mounting groove 14 and is fixedly connected to the main body 10 of the glue brushing device by a set screw, ensuring the stable installation of the barrel 21 and providing a solid foundation for the entire glue dispensing system. The pneumatic push rod 22 is mounted on the barrel 21, and glue is stored in the barrel 21. The pneumatic push rod 22 is used to extrude the glue stored in the barrel 21 at a stable speed and dosage. This process not only ensures the continuity of glue delivery, but also avoids the problem of uneven glue coating caused by excessive or insufficient glue. The transmission end of the pneumatic device is connected to the pneumatic push rod 22, which is controlled by the control unit to drive the pneumatic push rod 22 to work, thereby indirectly controlling the extrusion speed and dosage of the glue, ensuring the consistency of the glue extrusion operation. The glue discharge needle 23 serves as the final port for glue output. It is installed at one end of the cylinder 21 close to the fiber groove 12 and is precisely positioned just above the glue brushing groove 11.

[0044] Furthermore, the fiber trough 12 passes through the middle of the glue brushing groove 11, effectively ensuring that the optical fiber 30 can evenly contact the glue during the process of traveling, improving the consistency and uniformity of the glue coating, and avoiding the glue from forming uneven dripping or accumulation on the surface of the optical fiber 30. The glue discharge needle 23 is in the shape of an elbow, and the glue outlet of the glue discharge needle 23 points vertically downward to the center of the glue brushing groove 11. This design accurately controls the extrusion direction and flow of the glue, so that the glue can accurately fall into the predetermined position in the glue brushing groove 11, reducing glue waste and improving glue coating efficiency. A threaded fixing hole 16 compatible with the set screw is provided on one side of the glue brushing device body 10, and the cylinder 21 is fixed in the glue brushing device body 10 by abutment.

[0045] The fiber trough 12 is provided with guide bevels 13 on opposite sides near one end of the glue discharge needle 23. The design of the guide bevels 13 helps the optical fiber 30 to smoothly transition into the fiber trough 12, reducing friction and damage to the optical fiber 30 and improving the threading efficiency of the optical fiber 30.

[0046] The glue dispensing device body 10 is provided with a mounting hole 15 adapted for the heater 40. This hole 15 extends through the body 10, ensuring that the heater 40 uniformly heats the entire device, resulting in more even heating of the glue. A temperature probe 50 is mounted on the side of the body 10 away from the fiber trough 12, optimizing the space layout and facilitating maintenance.

[0047] Furthermore, the depth of the glue brushing groove 11 is greater than the depth of the fiber running groove 12, so that the glue brushing groove 11 can carry a certain amount of glue, ensuring full contact between the optical fiber 30 and the glue, so that the glue can fully wrap the optical fiber 30, ensuring the quality of the glue coating.

[0048] The liquid level of the glue held in the glue brushing groove 11 is no higher than 0.5 mm from the bottom of the fiber trough 12, and the height of the glue submerged above the optical fiber 30 is 0.1 to 0.2 mm. Such liquid level control ensures that the optical fiber 30 can fully contact the glue, while avoiding excessive glue forming an excessively thick glue layer on the surface of the optical fiber 30, which affects subsequent process processing and causes waste.

[0049] According to the diameter of the optical fiber 30 commonly used in the industry, the width of the fiber trough 12 is generally not more than 0.25 mm, which not only accurately limits the travel space of the optical fiber 30, but also effectively prevents the optical fiber 30 from deflecting and shaking during the glue coating process, ensuring the accuracy and stability of the glue coating, and preventing the glue in the glue brushing groove 11 from overflowing to both sides through the fiber trough 12.

[0050] Specific working process:

[0051] First, the glue-dispensing syringe 20, which contains glue, is mounted on the main body 10 of the glue-applying device and then heated by the heating element 40. The optical fiber 30 is then placed on the fiber trough 12 and passed through the glue-applying trough 11. A preset amount of glue is then injected into the trough 11, ensuring that the glue completely submerges the optical fiber 30. As the optical fiber 30 is pulled to perform the fiber-winding process, the glue-dispensing syringe 20, driven by the pneumatic push rod 22, causes the glue inside to drip onto the optical fiber 30 at a preset rate. A looping device is also installed on the side of the glue-applying device used for fiber-winding loop tape adhesive. This device operates to force the optical fiber 30 through the glue-applying trough 11 at a preset rate, coating it with glue.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the principles of the present invention should be included in the scope of protection of the present invention.
