Description

Technical Field

[0001] This utility model relates to the field of online coating of optical fibers, and in particular to an integrated coating and coloring device for drawing towers. Background Technology

[0002] The basic structure and functions of optical fiber include: core layer, mainly used for optical signal transmission; cladding layer, which creates the conditions for total internal reflection; inner coating layer, which is a buffer layer and has the function of resisting micro-bending loss; and outer coating layer, which is beneficial to the wear resistance, low-temperature performance and bending resistance of the optical fiber. Coloring involves uniformly coating a layer of ink on the surface of the optical fiber for distinguishing the fibers in a bundle.

[0003] In the field of optical fiber manufacturing, traditional optical fiber coating and coloring are carried out in two steps. First, optical fibers with inner and outer coatings are drawn using a drawing tower. The fibers then pass through a screening machine and testing equipment to verify their strength, geometry, and optical properties. Once they meet the product specifications, they are transferred to a coloring machine to coat with an ink layer, ultimately forming the desired ink-coated optical fiber. During the screening, testing, and transfer processes, airborne particles can adhere to the fiber surface and become trapped in the ink layer, affecting fiber performance. Furthermore, coloring the screened fiber not only wastes manpower and time but also results in secondary scrap, reducing the yield length of finished optical fibers. Utility Model Content

Detailed Implementation

[0023] Example 1:

[0024] like Figure 1-8 In the present invention, a coating and coloring integrated device for a wire drawing tower includes an inner coating device 5, an outer coating device 6, and a coloring device 7 arranged sequentially from high to low on a wire drawing tower 4. A curing oven 8 is provided below each of the inner coating device 5, the outer coating device 6, and the coloring device 7. Each of the inner coating device 5, the outer coating device 6, and the coloring device 7 includes an adjustment platform 2 and a coater 1 disposed on the adjustment platform 2. The coater 1 includes a mold body 101 with a cavity. An opening 109 is provided at the upper end of the mold body 101, and a through hole 102 is provided at the lower end of the mold body 101. A positive pressure protective cover 3 is also provided at the upper end of the coater 1. An optical fiber inlet 301 is provided at the upper end of the positive pressure protective cover 3, and a positive pressure gas inlet 302 is provided on the side wall of the positive pressure protective cover 3.

[0025] The opening 109, the through hole 102, and the fiber optic inlet 301 of the mold body 101 are coaxially aligned.

[0026] The optical fiber passes through the optical fiber inlet 301, passes through the upper opening 109 of the mold body 101 and the inner cavity of the mold body 101, and then exits through the through hole 102.

[0027] After the pressure-set coating or ink enters the inner cavity of the mold body 101, it adheres to the outer wall of the optical fiber. The inner diameter of the through hole 102 is slightly larger than the diameter of the optical fiber. Since the coating or ink has a large viscosity, it is difficult to overflow from the cavity between the through hole 102 and the optical fiber. The coating or ink can be continuously stored in the inner cavity of the mold body 101, so that the outer wall of the optical fiber can contact the coating.

[0028] The drawing tower 4 is generally located in a Class 100 cleanroom and is equipped with a downward laminar flow air supply device 10 at the top, which can ensure unidirectional airflow, avoid eddies that cause particle deposition, and improve the cleanliness of the coating and coloring environment.

[0029] Clean gas is introduced through the positive pressure gas inlet 302. Since the coating at the end near the coating device 1 blocks the cavity between the through hole 102 and the optical fiber, it is a closed end. The gas overflows upward from the mold body 101, preventing dust and other impurities from entering.

[0030] The coating or ink contains adhesive. After the optical fiber passes through the coating or coloring device, it needs to go through a curing oven 8, where the coating layer is solidified by heating and ultraviolet light irradiation. Each curing oven 8 is also equipped with a diameter gauge 9, which measures the diameter of the optical fiber in two orthogonal directions online using laser detection.

[0031] In a preferred embodiment, the coating device 1 includes a housing 103, a base sleeve 104 is fitted inside the housing 103, an annular groove 105 is provided on the outer wall of the base sleeve 104, a feed hole 106 is provided on the outer wall of the housing 103, the feed hole 106 communicates with the annular groove 105, an upper cavity 108 is provided inside the base sleeve 104, the inner cavity of the mold body 101 communicates with the upper cavity 108, and a first through hole 107 is provided on the side wall of the upper cavity 108, which communicates with the annular groove 105.

[0032] Multiple first through holes 107 can be provided along the circumference.

[0033] In a preferred embodiment, the mold body 101 is provided with a stop cap 114 at its lower end, and the base sleeve 104 is also provided with a recessed cavity 113. A positioning hole 116 is provided between the upper recessed cavity 108 and the lower recessed cavity 113. The upper and lower ends of the base sleeve 104 are respectively provided with an upper core 110 and a lower core 111. An avoidance through hole 112 is provided in the center of the upper core 110 and the lower core 111. The mold body 101 is inserted into the recessed cavity 113 and passes through the positioning hole 116 so that the opening 109 is placed in the upper recessed cavity 108. The lower core 111 abuts against the lower end of the stop cap 114, and the lower end of the upper core 110 is inserted into the opening 109. The inner cavity sidewall of the mold body 101 is provided with a plurality of second through holes 115, and the second through holes 115 communicate with the upper recessed cavity 108.

[0034] The clearance through hole 112 of the upper core 110 is coaxially aligned with the opening 109 of the mold body 101, and the clearance through hole 112 of the lower core 111 is coaxially aligned with the through hole 102. The clearance through hole 112 is used for optical fiber to pass through.

[0035] The lower top core 111 is threadedly connected to the side wall of the lower recessed cavity 113, and the upper top core 110 is threadedly connected to the inner wall of the upper recessed cavity 108.

[0036] The clamping wall between the upper cavity 108 and the lower cavity 113 is provided with a through positioning hole 116 for inserting and installing the mold body 101.

[0037] A flange structure can be installed on the outer wall of the casing 103 for easy installation.

[0038] When not in operation, the lower core 111 can be rotated from below and quickly removed to extract and replace the mold body 101, and the internal flow channels can be cleaned. The remaining liquid can be discharged from the sinking cavity 113.

[0039] Since the diameter of the through hole 102 is close to the diameter of the optical fiber, and there is a certain height difference between the fiber inlet at the top and the fiber outlet at the bottom of the coater 1, the horizontal position and pitch angle of the coater 1 must be adjusted to prevent the optical fiber from forming an angle or interfering with the hole wall, which would result in uneven coating.

[0040] In a preferred embodiment, the adjustment platform 2 includes a bidirectional displacement stage 201, on which a horizontal adjustment stage 202 is provided. The bidirectional displacement stage 201 and the horizontal adjustment stage 202 have a central cutout, and the horizontal adjustment stage 202 is used to connect the coating device 1.

[0041] The opening of the U-shaped groove structure 207 does not face the wire drawing tower 4, which facilitates the installation of the coating device 1.

[0042] In a preferred embodiment, the bidirectional displacement stage 201 includes a base connecting seat 203 and a first translation plate 204. The lower end of the first translation plate 204 is provided with a first sliding groove 206, which is slidably connected to the base connecting seat 203. The first translation plate 204 is provided with a second sliding groove 208, in which a slidable second translation plate 205 is disposed. The moving directions of the first translation plate 204 and the second translation plate 205 are perpendicular. The horizontal adjustment stage 202 includes a first swing stage. The first swing table 209 and the second swing table 210 are connected to the coating device 1. One end of the first swing table 209 is hinged to the second translation plate 205. The second swing table 210 is hinged to the first swing table 209. The hinge axis of the first swing table 209 is perpendicular to the hinge axis of the second swing table 210. The bidirectional displacement table 201, the first translation plate 204, the second translation plate 205, the first swing table 209 and the second swing table 210 are all provided with a U-shaped groove structure 207 with the opening facing the same side.

[0043] To prevent interference, the width and depth of the U-shaped groove structure 207 at the lower end are larger, while the U-shaped groove structure 207 of the second swing table 210 is the smallest. The shell 103 of the coating device 1 is inserted into the U-shaped groove structure 207, and the flange structure is fixed at the fixing hole on the second swing table 210.

[0044] In a preferred embodiment, the first swing platform 209 is provided with a first stop screw 218 at the end away from the hinge axis. The first stop screw 218 is threadedly connected to the first swing platform 209 and its end passes through the first swing platform 209 to abut against the second translation plate 205. The second swing platform 210 is provided with a second stop screw 219 at the end away from the hinge axis. The second stop screw 219 is threadedly connected to the second swing platform 210 and its end passes through the second swing platform 210 to abut against the first swing platform 209.

[0045] The first stop screw 218 and the second stop screw 219 must not be located on the axis of their respective hinge shafts.

[0046] Rotating the first stop screw 218 can adjust the front-to-back angle of the first swing table 209, and rotating the second stop screw 219 can adjust the left-to-right angle of the second swing table 210. Therefore, the coating device 1 installed on the second swing table 210 can be adjusted to a horizontal angle.

[0047] In a preferred embodiment, the second translation plate 205 is provided with a hinge ear 211, and the first swing table 209 is provided with a rotating sleeve 212. The rotating sleeve 212 includes a first sliding groove 206 and a threaded section 217, and is also provided with a tightening screw 213. The hinge ear 211 and the rotating sleeve 212 are provided with a light hole 214. The bottom end of the light hole 214 of the rotating sleeve 212 is provided with a threaded hole 215. The optical axis section 216 of the tightening screw 213 is inserted into the light hole 214 of the hinge ear 211 and the rotating sleeve 212, and the threaded section 217 of the tightening screw 213 is sleeved with the threaded hole 215 of the rotating sleeve 212.

[0048] Tightening screw 213 serves both a positioning function and increases the pressure and friction between the hinge lug 211 and the rotating sleeve 212, thereby locking the angle of the first swing table 209.

[0049] The hinge shaft structure of the second swing stage 210 is similar to that of the first swing stage 209, and its position is located at the bottom end of its U-shaped groove structure 207.

[0050] The side walls of the first sliding groove 206 and the second sliding groove 208 are also provided with threaded locking screws 220. One end of the locking screw 220 abuts against the respective sliding surface, which can lock the horizontal position of the first translation plate 204 and the second translation plate 205.
