Description

Technical Field

[0001] This invention relates to the field of optical fiber color stripe coating equipment technology, and more specifically, to an optical fiber color stripe coating apparatus. Background Technology

[0002] The color of optical fiber is mainly used to distinguish the fiber type, core order, and application. Yellow represents single-mode fiber (long-distance high-speed transmission), orange represents multimode fiber (short-distance high-bandwidth), and other colors such as blue, green, and brown are used to identify the core order or special scenarios. The above-mentioned optical fibers are single-color. With the market demand for high-density, high-core-count optical cables and special-purpose optical cables, single-color optical fibers can no longer meet the distribution needs. Therefore, it is necessary to coat the existing single-color optical fibers with different colored stripes for further classification.

[0003] Existing fiber optic color stripe coating devices have the following problems: First, existing fiber optic color stripe coating devices can only coat a single color stripe at a time. When multiple color stripes need to be coated, the fiber needs to be put back into the coating chamber for a second coating, which is inefficient. At the same time, repeated coating results in large dimensional deviations in the coating of each color stripe. Second, the existing coating chamber vibrates significantly during the rotation coating process, resulting in uneven coating of the color stripe and large deviations in the position and size of the color stripe from the target coated color stripe. Summary of the Invention

[0004] In view of the prior art, the present invention provides an optical fiber color stripe coating device. This optical fiber color stripe coating device can replace coating chambers with different numbers of feed inlets to achieve coating of multiple color stripes at one time, thereby improving coating efficiency and reducing the dimensional deviation of the color stripe coating in one-time coating. At the same time, the coating chamber can be rotated to prevent shaking, thereby improving the stability of the coated color stripe and ensuring that the position and size of the coated color stripe meet the target requirements.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An optical fiber color stripe coating device includes a base. From left to right, the upper surface of the base is provided with an inverted concave bracket, two parallel support plates, and a tension spring rod. The tension spring rod is connected downwards at the center of the lower surface of the transverse section of the inverted concave bracket. A tension wheel is connected to the top of the tension spring rod via a rotating shaft. Rotary bearings are embedded in the upper ends of the two parallel support plates. The central rotating part of the rotary bearing closer to the inverted concave bracket passes through a connecting rod, while the central rotating part of the rotary bearing farther from the inverted concave bracket passes through a telescopic connecting rod. The telescopic connecting rod is limited by tightening bolts on the outer side of the non-telescopic section. The inner ends of the connecting rod and the telescopic connecting rod are fixedly connected to cylindrical brackets. A detachable coating chamber is installed between the cylindrical brackets. The coating chamber, the connecting rod, and the telescopic connecting rod are all machined with through holes, and optical fibers pass through the through holes. The two ends of the optical fibers pass through tensioning wheels on the corresponding sides for tensioning. The coating chamber has several vertically aligned ink and paint inlet holes and ink and paint extrusion holes. The ink and paint inlet holes and ink and paint extrusion holes are connected by an annular through groove. A sleeve with external threads is screwed into the ink and paint inlet hole, and an ink and paint injection cylinder is screwed onto the sleeve.

[0006] As a further optimization of this solution, the inner side center area of ​​the cylindrical card holder is provided with an inward protrusion that extends into the blind grooves on both sides of the coating chamber. The outer side of the protrusion is provided with several sealing rings, which are aligned and embedded in the recessed grooves on the inner side of the blind grooves on both sides of the coating chamber. The inner side of the cylindrical card holder is provided with several locking blocks with triangular cross-sections around its perimeter, which are aligned and embedded in the locking grooves on the outer side of both sides of the coating chamber.

[0007] As a further optimization of this solution, stabilizing components are provided on both the telescopic section of the telescopic linkage and the connecting rod. These stabilizing components include a collar and a connecting ring. The collar is fitted onto both the telescopic section of the telescopic linkage and the connecting rod. Magnetic push rods are provided outwards at the top, bottom, left, and right positions on the outer side of the collar. The outer end of each magnetic push rod enters a circular blind groove at the corresponding position on the connecting ring. The diameter of the circular blind groove is larger than the diameter of the magnetic push rod. An electromagnetic coil is connected to the bottom surface of the circular blind groove via a stud. A controller with a built-in battery is provided on the outer side of the connecting ring. A gyroscope sensor is fixed to the outer cross-section of the collar. Both the gyroscope sensor and the electromagnetic coil are connected to the controller via wiring. The lower end of the connecting ring is fixedly connected to the upper surface of the base via a support column.

[0008] As a further optimization of this solution, the central rotating part of the rotating bearing of the telescopic connecting rod installed in the two parallel support plates is connected to the output shaft of the drive motor through a transmission chain. The drive motor is fixed on the upper surface of the base, and the transmission chain is located in the hollow area inside the support plate.

[0009] As a further optimization of this solution, the telescopic link is provided with two limiting plates on the left and right sides of the telescopic section, which are located on both sides of the collar on the telescopic link.

[0010] As a further optimization of this solution, the number of ink / coating feed holes and ink / coating extrusion holes is the same as the number of color strips coated in one go.

[0011] Compared with existing technologies, the beneficial effects of the present invention are as follows: In this invention, by designing structures such as telescopic connecting rods, connecting rods and cylindrical brackets on both sides, the telescopic connecting rods can be retracted inwards, so that the cylindrical bracket on that side is moved away from the coating chamber. This allows the coating chamber with different numbers of ink coating inlet holes and ink coating extrusion holes to be removed and replaced from the middle, catering to the color stripe coating requirements of different optical fibers. This enables the coating of multiple color stripes at one time, improving coating efficiency and reducing the dimensional deviation of color stripe coating in one-time coating. In this invention, a stable component structure is designed on the telescopic link and the link itself. The collar vibrates together with the telescopic link, the link, and the coating chamber. When an up-down or left-right offset occurs, the corresponding magnetic push rod will move. This movement signal is detected by the gyroscope sensor on the outside of the collar and transmitted to the controller. The controller controls the electromagnetic coil on each side to generate a magnetic field, which uses magnetic force to reset the magnetic push rod to its initial position, reducing the vibration of the coating chamber and performing a rotational anti-shake operation on the coating chamber. This improves the stability of the coated color strip and ensures that the position and size of the coated color strip meet the target requirements. Attached Figure Description

[0014] To address the issues that existing fiber optic color stripe coating devices can only coat a single color stripe at a time, and when multiple color stripes need to be coated, the fiber needs to be put back into the coating chamber for a second coating, which is inefficient. In addition, repeated coatings result in large dimensional deviations in the coating of each color stripe, and the existing coating chamber vibrates significantly during the rotation coating process, leading to uneven color stripe coating and large deviations in the position and size of the color stripe from the target color stripe. like Figure 1 and Figure 2As shown, this application includes a base 1. From left to right, the upper surface of the base 1 is provided with an inverted concave bracket 3, two parallel support plates 2, and a tension spring rod 4. The tension spring rod 4 is connected downward at the center of the lower surface of the horizontal section of the inverted concave bracket 3. The top of the tension spring rod 4 is connected to a tension wheel 5 through a rotating shaft. Rotary bearings 15 are embedded in the upper ends of the two parallel support plates 2. The central rotating part of the rotary bearing 15 on the side closer to the inverted concave bracket 3 passes through the connecting rod 14, and the central rotating part of the rotary bearing 15 on the other side away from the inverted concave bracket 3 passes through the telescopic connecting rod 7. The telescopic connecting rod 7 is tightened and limited by bolts on the outside of the non-telescopic section. The inner ends of the connecting rod 14 and the telescopic connecting rod 7 are fixedly connected to cylindrical brackets 12. A detachable coating chamber 10 is installed between the cylindrical brackets 12. Through holes 17 are machined at the center of the coating chamber 10, the connecting rod 14, and the telescopic connecting rod 7, and optical fibers 6 pass through the through holes 17. The two ends of the optical fibers 6 pass through the tension wheels 5 on the corresponding sides for tensioning. like Figure 3 As shown, the coating chamber 10 has several vertically aligned ink and paint inlet holes 20 and ink and paint extrusion holes 18. The ink and paint inlet holes 20 and ink and paint extrusion holes 18 are connected by an annular groove 19. A sleeve 22 with external threads is screwed into the upper part of the ink and paint inlet hole 20, and an ink and paint injection cylinder 21 is screwed tightly onto the sleeve 22. like Figure 2 As shown, the inner side of the cylindrical card holder 12 has an inward protrusion in the central area, and the protrusion extends into the blind grooves on both sides of the coating chamber 10. The outer side of the protrusion has several sealing rings, and several sealing rings are aligned and embedded in the recessed grooves on the inner side of the blind grooves on both sides of the coating chamber 10. The inner side of the cylindrical card holder 12 has several card blocks 13 with triangular cross-sections around its perimeter, and the card blocks 13 are aligned and embedded in the card grooves 16 on the outer side of both sides of the coating chamber 10. like Figure 4 and Figure 5 As shown, stabilizing components are provided on the telescopic section of the telescopic link 7 and the link 14. The stabilizing components include a collar 24 and a connecting ring 8. The collar 24 is fitted onto the telescopic section of the telescopic link 7 and the link 14. Magnetic push rods 25 are provided outward at the top, bottom, left, and right positions on the outer side of the collar 24. The outer end of the magnetic push rod 25 enters the corresponding position of the connecting ring 8 and has a circular blind groove 23. The diameter of the circular blind groove 23 is larger than the diameter of the magnetic push rod 25. An electromagnetic coil 29 is connected to the bottom surface of the circular blind groove 23 through a stud 30. A controller 27 with a built-in battery is provided on the outer side of the connecting ring 8. A gyroscope sensor 26 is fixed on the outer cross section of the collar 24. The gyroscope sensor 26 and the electromagnetic coil 29 are both connected to the controller 27 through a line 28. The lower end of the connecting ring 8 is fixedly connected to the upper surface of the base 1 through a support column 9. Specifically, the central rotating part of the rotating bearing 15 of the telescopic link 7 installed in the two parallel support plates 2 is connected to the output shaft of the drive motor through the transmission chain. The drive motor is fixed on the upper surface of the base 1. The transmission chain is located in the hollow area inside the support plate 2. The telescopic section of the telescopic link 7 is provided with two left and right limiting plates 11. The two left and right limiting plates 11 are located on both sides of the collar 24 on the telescopic section of the telescopic link 7. During operation, depending on the number of color stripes to be coated, a coating chamber 10 with the same number of ink coating inlet holes 20 and ink coating extrusion holes 18 is selected to meet the color strip coating requirements of different optical fibers, so as to achieve coating of multiple color stripes at one time, improve coating efficiency, and reduce the dimensional deviation of color strip coating in one coating. The telescopic connecting rod 7 on one side is retracted, aligning the slot 16 and the locking block 13 on one side of the coating chamber 10 and embedding them into the outer side of the cylindrical locking seat 12 on one side of the connecting rod 14. Then, the telescopic section of the telescopic connecting rod 7 is extended inward, aligning and locking the cylindrical locking seat 12 on the other side into the coating chamber 10, thus fixing the coating chamber 10. The telescopic connecting rod 7 is limited by bolts, and the optical fiber 6, which has been coated with the base color, is passed through the through hole 17. Both ends are tensioned by tensioning wheels 5. The UV ink coating is injected from the ink coating injection cylinder 21 into the ink coating inlet hole 20, and flows into the ink coating extrusion hole 18 through the annular through groove 19. The drive motor is started by the external control panel and power supply, which drives the coating chamber 10 to rotate, and the ink coating is extruded from the ink coating extrusion hole 18. The coating is extruded from point 8 and applied to the surface of optical fiber 6 at different transverse positions to form color stripes. The color stripes are then UV cured and molded. During the process, the collar 24, telescopic connecting rod 7, connecting rod 14, and coating chamber 10 vibrate together. When the coating chamber 10 shifts up, down, left, or right, the corresponding magnetic push rod 25 will move. This movement signal is detected by the gyroscope sensor 26 on the outside of the collar 24 and transmitted to the controller 27. The controller 27 controls the electromagnetic coil 29 on each side to generate a magnetic field, which resets the magnetic push rod 25 to its initial position through magnetic force, reducing the vibration of the coating chamber 10 and performing a rotation anti-shake operation on the coating chamber 10 to improve the stability of the coated color strips and ensure that the position and size of the coated color strips meet the target requirements.
