Description

Technical Field

[0001] The invention relates to the field of optical fiber coating, and in particular to an optical fiber rod coating mechanism. Background Art

[0002] The existing optical fiber rod coating process is mostly to evaporate or sputter the coating material under vacuum conditions by heating or ion bombardment to form gaseous atoms or molecules, and then deposit them on the substrate surface to form a thin film. However, the existing optical fiber coating technology generally has the disadvantage of not being comprehensive enough. This not only affects the optical performance of the optical fiber, but also may lead to low production efficiency and unstable product quality. Summary of the invention

[0003] In view of the above, the object of the present invention is to provide a coating mechanism for a brazing rod in order to address the problem that the existing coating may not be comprehensive enough.

[0004] A laser soldering rod coating mechanism in this scheme includes a rotating bracket capable of self-rotation, on which a plurality of support arms spaced apart around the rotating axis of the rotating bracket are mounted, on which a rotatable roller bracket is mounted, on which a plurality of laser soldering rod holders spaced apart around the rotating axis of the roller bracket are mounted, and the laser soldering rod holders are rotatably mounted on the roller bracket.

[0005] Furthermore, a fixed circular track is provided below the rotating bracket, and the drum bracket is provided with a roller, which forms a friction fit with the circular track. When the rotating bracket rotates, the roller rotates due to the friction force with the circular track, thereby driving the drum bracket to rotate.

[0006] Furthermore, the drum bracket is provided with an upper support frame and a lower support frame. The upper support frame is clamped on a support body arranged on the lower side of the top of the rotating bracket, and the lower support frame is clamped in a clamping groove arranged at the bottom of the support arm.

[0007] Furthermore, an installation shaft passes through the upper support frame, and the upper support frame is clamped on the support body through the installation shaft. A movable plate is installed under the support arm, and the card slot is formed on the movable plate. When the position of the movable plate is adjusted relative to the support arm, the roller bracket can rotate around the installation shaft to adjust its own angle.

[0008] Furthermore, the roller bracket is provided with a special-shaped shaft, the two ends of which are respectively mounted on the upper support frame and the lower support frame through bearings, and the lower end of the special-shaped shaft passes through the lower support frame and is mounted with the roller; An upper disc and a lower disc are also installed on the special-shaped shaft, and the optical soldering rod is inserted and fixed on the upper disc and the lower disc. The optical soldering rod holder is arranged on the upper disc around the special-shaped shaft. A bearing is arranged between the optical soldering rod holder and the upper disc, and a driven shaft is arranged on the optical soldering rod holder. The driven shaft passes through the upper disc and is provided with a moving gear at the end. A matching stationary gear is installed on the upper support frame, and the stationary gear is arranged at the center of all the moving gears and meshes with them.

[0009] Beneficial effects: The present invention discloses a coating mechanism for a three-stage public self-rotating optical fiber rod. The optical fiber rod is fixed on an optical fiber rod bracket, which is connected to a rotating bracket through a roller bracket to realize the self-rotation and revolution of the optical fiber rod, thereby achieving a three-stage self-rotation and self-rotation effect. By using this mechanism, the optical fiber rod can be more comprehensively coated, thereby improving the quality of the coating.

[0010] In addition, the angle of the roller support can be adjusted to cater to the evaporation angle, thereby improving the quality of the coating. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0012] 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.

[0013] Reference Figure 1 to Figure 2The optical soldering rod coating mechanism shown includes a rotating bracket 100 capable of self-rotation, on which a plurality of support arms 200 spaced apart around the rotation axis of the rotating bracket 100 are mounted, on which a rotatable roller bracket 300 is mounted, on which a plurality of optical soldering rod brackets 400 spaced apart around the rotation axis of the roller bracket 300 are mounted, and the optical soldering rod bracket 400 is rotatably mounted.

[0014] In this mechanism, the optical soldering rod 500 is fixed on the optical soldering rod support 400 and connected to the rotating support 100 through the roller support 300, so that the optical soldering rod 500 can complete the revolution motion while rotating, thereby achieving the effect of three-level revolution and rotation. The revolution refers to two levels of revolution, one is that the optical soldering rod 500 revolves around the rotation axis of the roller support 300, and the other is that the optical soldering rod 500 is connected to the rotating support 100 through the roller support 300, so that it can also revolve around the rotation axis of the rotating support 100.

[0015] Such a design is mainly aimed at the process of evaporation of coating materials. By utilizing the above mechanism, the optical soldering rod 500 can be more comprehensively coated, thereby improving the quality of the coating.

[0016] In this embodiment, a flange 101 is provided on the top of the rotating bracket 100 , and the flange 101 can be used to connect a driving structure such as a motor to drive the rotating bracket 100 to rotate.

[0017] In this embodiment, a fixed circular track 600 is provided below the rotating bracket 100, and the roller bracket 300 is provided with a roller 301, and the roller 301 forms a friction fit with the circular track 600. When the rotating bracket 100 rotates, the roller 301 rotates due to the friction force with the circular track 600, so that the roller 301 will rotate with the roller bracket 300, realizing the self-rotation of the roller bracket 300. This design is very clever, because it uses the power of rolling friction, so that the roller bracket 300 does not need to be provided with a separate power, which can reduce energy consumption.

[0018] In this embodiment, the roller bracket 300 is provided with an upper support frame 302 and a lower support frame 306. The upper support frame 302 is mounted on the support body 102 provided on the lower side of the top of the rotating bracket 100, and the lower support frame 306 is mounted in the card slot 201 provided at the bottom of the support arm 200. Such a design can facilitate the disassembly and assembly operation of the roller bracket 300, so as to realize the convenient loading and unloading of the optical soldering rod 500. Such a design can not only improve production efficiency, but also reduce the time and labor intensity of manual operation, and improve the level of automation of production. At the same time, such a design is also convenient for maintenance and cleaning, which can greatly reduce the cost caused by maintenance and cleaning.

[0019] In this embodiment, the upper support frame 302 is penetrated by a mounting shaft 302a, and the upper support frame 302 is clamped on the support body 102 through the mounting shaft 302a. A movable plate 202 is installed below the support arm 200, and the clamping groove 201 is formed on the movable plate 202. When the position of the movable plate 202 is adjusted relative to the support arm 200, the roller bracket 300 can rotate around the mounting shaft 302a to adjust its own angle. This structure is mainly considered to be able to adjust the angle with the evaporation source. For example, when the evaporation source is in the middle of the rotating bracket 100, adjusting the angle of the roller bracket 300 can cater to the evaporation angle, which can improve the quality of the coating. Specifically, a waist hole is provided on the movable plate 202, and the movable plate 202 is fixed to the support arm 200 by screws. When the screws are loosened, the position of the movable plate 202 can be adjusted through the waist hole. The advantage of this design is that the structure is simple and convenient.

[0020] In this embodiment, the roller bracket 300 is provided with a special-shaped shaft 303, and the two ends of the special-shaped shaft 303 are respectively installed on the upper support frame 302 and the lower support frame 306 through bearings 700. The lower end of the special-shaped shaft 303 passes through the lower support frame 306 and is installed with the above-mentioned roller 301. The upper disc 304 and the lower disc 305 are also installed on the special-shaped shaft 303. The optical soldering rod 500 is inserted and fixed on the upper disc 304 and the lower disc 305. The optical soldering rod bracket 400 The special-shaped shaft 303 is arranged on the upper disk 304, a bearing 700 is arranged between the optical soldering rod holder 400 and the upper disk 304, and a driven shaft 401 is arranged on the optical soldering rod holder 400, the driven shaft 401 passes through the upper disk 304 and is provided with a moving gear 402 at the end, and a matching stationary gear 403 is installed on the upper support frame 302, and the stationary gear 403 is arranged at the center of all the moving gears 402 and meshes with them. When the special-shaped shaft 303 rotates with the roller 301, it can drive the upper disc 304 and the lower disc 305 to rotate, and the light soldering rod 500 installed on the upper disc 304 and the lower disc 305 can also realize the revolution around the rotation axis of the roller bracket 300, that is, the special-shaped shaft 303; at the same time, when the upper disc 304 rotates, because the fixed gear 403 is fixedly installed on the upper support frame 302, the light soldering rod bracket 400 on the upper disc 304 can realize the self-rotation of the light soldering rod bracket 400 through the meshing of the moving gear 402 and the fixed gear 403. This design is mainly that the special-shaped shaft 303 can not only drive the roller bracket 300 to rotate, but also realize the self-rotation of the light soldering rod bracket 400 by gear transmission, further improving the energy utilization efficiency.

[0021] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
