Description

Technical Field

[0001] This utility model relates to the field of fiber array coating technology, and in particular to a FA fiber array coating device. Background Technology

[0002] A fiber optic array is formed by mounting a bundle of optical fibers or a strip of optical fibers at specified intervals on a substrate. In optical communication, a fiber optic array mainly consists of a substrate, a pressure plate, and optical fibers. Typically, multiple grooves are cut into the surface of the substrate, and the pressure plate presses and secures the optical fibers inserted into these grooves.

[0003] In the manufacturing process of optical fibers, in order to protect the optical fibers and improve their performance, a layer of polymer material is often coated on the outside of the optical fiber cladding to provide additional mechanical strength protection for the optical fiber. Through coating treatment, the water resistance, aging resistance, flexibility and mechanical strength of the optical fiber can be significantly improved.

[0004] Based on the above, the inventors believe that currently, fiber arrays are often cleaned to avoid contamination of the fiber surface with impurities. However, there is often a certain gap between the cleaning and coating processes. Before coating, the fiber is easily contaminated with impurities due to external factors, making it difficult to perform a quick secondary cleaning and dust removal process before coating.

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] This utility model embodiment specifically provides an FA fiber array coating device, please refer to... Figures 1-6 It includes a coating machine 1, which is equipped with a feed port 11 for feeding optical fiber coating materials.

[0037] The coating machine 1 is an existing vacuum coating machine, which is equipped with a control panel 12 for operation. The specific working method and principle of the coating machine 1 are existing technologies and are relatively well known to those skilled in the art, so they will not be described in detail here.

[0038] The coating device also includes a dust removal component 2 installed outside the feed inlet 11. The dust removal component 2 includes a bracket 3 fixedly connected to the outside of the coating machine 1, a dust removal component 4 set on the bracket 3, a feed component 5 connected to the surface of the bracket 3, and an installation component 6 for placing the fiber array. During coating, the installation component 6 feeds the fiber array into the dust removal component 4 and the feed inlet 11 in sequence through the feed component 5 for dust removal treatment before coating.

[0039] Furthermore, the dust removal component 4 includes a support rod 41 connected to the bracket 3 on the outside and a dust removal frame 42 fixed on the support rod 41. The dust removal frame 42 is provided with a dust removal air duct for connecting to the air supply component. When the fiber array is to be fed into the feed port 11 for coating, the dust removal air force can be output through the dust removal air duct to remove the dust and ash from the surface of the fiber array.

[0040] Specifically, the dust removal frame 42 is a circular structure coaxially distributed with the feed inlet 11. The dust removal duct includes an annular groove 421 opened inside the dust removal frame 42. An air outlet 422 communicating with the inner side of the dust removal frame 42 is opened on the annular groove 421. The air outlet 422 has an angle of less than 90° with the feed direction of the fiber array, so that when the fiber array is fed, the dust removal air can remove dust from the surface of the fiber array in an inclined blowing manner.

[0041] The gas delivery component includes a delivery pipe 43 that is embedded in the dust removal frame 42 and communicates with the annular through groove 421, and an output component 44 that is connected to the other end of the delivery pipe 43. The delivery pipe 43 is a flexible hose, and the output component 44 is an air pump or an exhaust fan. The delivery component 44 is fixedly installed on the outside of the bracket 3.

[0042] In this embodiment, four air outlets 422 are arranged in an array along the circumferential direction of the dust removal frame 42. When the fiber array is fed in, the output component 44 will generate dust removal wind, and the dust removal wind will remove dust from the surface of the fiber array along the air outlets 422, so as to further improve the surface cleanliness of the fiber array.

[0043] The feeding component 5 includes a slide rail 51 whose bottom end is fixedly connected to the bracket 3. An electric slider 52 is provided on the slide rail 51 and slides along it. The surface of the electric slider 52 is fixedly connected to the support frame 53. The slide rail 51 and the electric slider 52 are commonly used electric sliding components on the market. They can be customized directly by professional manufacturers during implementation. The electric slider 52 can drive the support frame 53 to move back and forth in a straight line along the slide rail 51 to facilitate feeding the fiber array into the coating machine 1 and removing it after coating.

[0044] Furthermore, the mounting component 6 includes a mounting frame 61 mounted on the support frame 53 at one end and a mounting block 62 fixed at the other end of the mounting frame 61. The mounting block 62 is provided with a positioning component 63 for stabilizing the fiber array. During coating, the fiber array can be mounted on the positioning component 63, and then the fiber can be fed and coated. The automatic feeding method replaces the manual clamping and feeding, improving the convenience of operation.

[0045] Specifically, the mounting block 62 has a slot 621 for inserting the fiber array substrate. The structure of the fiber array is a prior art well known to those skilled in the art. Generally, the head of the fiber array is placed on the substrate, and then the pressure plate moves down to fix the fiber array on the substrate. The coating is applied to the array fiber bundle located behind the substrate, which will not be described in detail here.

[0046] The positioning component 63 includes a mounting base 631 fixedly connected to the outside of the mounting block 62 and a support rod 632 mounted on the mounting base 631 by sliding up and down. The upper and lower ends of the support rod 632 are respectively fixed with a pressure plate 633 and a counterweight block 634. The pressure plate 633 is used to press down the pressure plate of the fiber array. The counterweight block 634 is a solid structure, preferably made of metal, and has high mass, which can make the pressure plate 633 press down on the pressure plate, so that the substrate is stably inserted into the slot 621.

[0047] During implementation, when it is necessary to remove the fiber optic array, simply push the support rod 632 upward to move the pressure plate 633 upward, and then remove the substrate from the slot 621. The same applies during installation.

[0048] During implementation, a through groove 611 is provided on the mounting frame 61, which runs through the upper and lower surfaces of the mounting frame 61, so that the bottom side of the fiber bundle will not be blocked during vacuum coating.

[0049] It is worth noting that in the above embodiment, the bottom end of the support rod 41 is fixed to the bracket 3, and the outer side of the mounting bracket 61 is fixedly connected to the support frame 53.

[0050] As another feasible installation method for the support rod 41 and mounting bracket 61 in this technical solution, the support rod 41 is provided with threads on the outside, and the outside of the support rod 41 is threadedly connected to the nut 45 through the threads. The bottom end of the nut 45 abuts against the bracket 3, and the outside of the support rod 41 is slidably connected to the bracket 3, so that the support rod 41 can slide up and down on the bracket 3. The height of the nut 45 can be adjusted by rotating the nut 45 to control the exposed height of the support rod 41 on the bracket 3, thereby adjusting the height of the dust removal frame 42 to adapt to the different heights of the feed inlets 11 on different types of coating machines 1.

[0051] Similarly, a slide rail 531 is provided on the support frame 53. The mounting frame 61 is threadedly connected to the fixing bolt 64 through the slide rail 531. The screw of the fixing bolt 64 passes through the slide rail 531 and is threadedly connected to the mounting frame 61, so that the nut of the fixing bolt 64 can be tightly pressed against the outside of the support frame 53, thereby fixing the mounting frame 61. When it is necessary to move the mounting frame 64, simply loosen the fixing bolt 64 so that the screw of the fixing bolt 64 can slide up and down along the slide rail 531. Then, when positioning is required, tighten the fixing bolt 64 so that the height of the mounting frame 61 can match the dust removal frame 42.

[0052] The above describes the basic principles, main features, and advantages of this utility model. The standard parts used in this utility model can all be purchased from the market, and the irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art, which will not be described in detail here.

[0053] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0054] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
