Description

Technical Field

[0001] The present application relates to the technical field of optical fiber clamps, and in particular to an optical fiber rotation mechanism. Background Art

[0002] As the main medium of optical waveguide, optical fiber has been widely used in various fields, such as optical fiber communication transmission, fiber laser manufacturing, semiconductor laser fiber coupling output and medical laser beauty industries. The optical fiber material is high-purity fused quartz, which is the same material as optical glass components. Various optical films can be plated on the surface of optical fiber glass. By depositing different film layers, the functional requirements of various fields can be met.

[0003] In the actual production process, the coating process of optical fiber is significantly different from that of glass components due to its round shape and length, which brings new difficulties and challenges to the coating industry. The existing vacuum coating machine is about 1.6 meters high and 0.7 meters in radius. It can only accommodate optical fiber about 1 meter long. One end of the optical fiber is clamped by the fixture inside the coating machine before vacuum coating.

[0004] The above technology has the following problems: Since the optical fiber is round, it is not easy to coat the outer diameter evenly; if the process is paused for manual flipping, the coating quality will be easily affected; if other flipping mechanisms on the market are used, they can only fix one end of the optical fiber, and the other end that is too long is not easy to flip or is easily broken due to constant twisting. Summary of the invention

[0005] The purpose of this application is to provide an optical fiber rotation mechanism to solve the problems existing in the prior art.

[0006] In order to solve the above technical problems, the present application provides the following technical solutions: an optical fiber rotation mechanism, comprising an optical fiber rotation bracket 1 and an optical fiber rotation bracket 2, the wall surface of the optical fiber rotation bracket 1 is provided with at least one through hole 1, and the wall surface of the optical fiber rotation bracket 2 is provided with at least one through hole 2; the center of the through hole 1 and the center of the through hole 2 are located on the same straight line; a pair of through holes 1 and 2 on either end side of the optical fiber rotation bracket 1 and the optical fiber rotation bracket 2 are suitable for allowing a connecting shaft to pass through, the connecting shaft is connected to a transmission shaft of a coating machine, and a driving gear is bonded to the outside of the connecting shaft; the remaining through holes 1 of the optical fiber rotation bracket 1 and the remaining through holes 2 of the optical fiber rotation bracket 2 are suitable for allowing a hollow tube to pass through, the interior of the hollow tube is suitable for allowing an optical fiber to pass through and be fixed to the optical fiber, and the exterior of the hollow tube is bonded to a driven gear; the gear of the driving gear is meshed with the gear of the driven gear, and the gears of adjacent driven gears are meshed with each other.

[0007] Through the above technical solution, the transmission shaft of the coating machine rotates to drive the connecting shaft to rotate, and the rotation of the connecting shaft drives the driving gear to rotate, thereby driving the driven gear to rotate, driving the hollow tube to rotate, and then driving the optical fiber to rotate. Therefore, the optical fiber can rotate with the rotating structure. During the coating process, the self-rotation of the optical fiber can make the outer diameter of the optical fiber uniformly coated, which can improve the coating quality. Since the rotating mechanism is only composed of a splint, a gear shaft, a hollow tube, etc., it has a simple structure and a small size, and is suitable for being placed inside the coating machine.

[0008] Furthermore, the opposing surfaces of the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2 are provided with grooves, bearings and gaskets: the bearing is provided in the groove, and the gasket is provided on the side of the bearing away from the groove; the two ends of the driven gear are respectively arranged on the gasket of the hollow tube, and the two ends of the driving gear are respectively arranged on the gasket of the connecting shaft.

[0009] Through the above technical solution, the bearing is used to isolate the movement force of the driven gear or the driving gear from being transmitted to the optical fiber rotating bracket 1 or the optical fiber rotating bracket 2. The gasket is used to isolate the rotation force of the driven gear from the bearing and protect the driven gear to reduce metal damage.

[0010] Furthermore, the hollow tube is suitable for fixing the middle position of the optical fiber.

[0011] Through the above technical solution, the middle section of the optical fiber is clamped and rotated, driving the two ends of the optical fiber to rotate, so that the optical fiber is evenly coated; because the force point of rotation is in the middle section of the optical fiber, it can be evenly transmitted to the two ends of the optical fiber, smoothly driving the two ends of the optical fiber to rotate, making the two ends of the optical fiber not easily broken.

[0012] Furthermore, the hollow tube and the optical fiber are fixedly connected by means of adhesive tape and a clamp.

[0013] Through the above technical solution, the hollow tube and the optical fiber are connected in a detachable manner, which facilitates the removal or replacement of the fixed position of the optical fiber.

[0014] Furthermore, a support ring 1 is provided between the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2, and the support ring 1 is located at four corners of the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2.

[0015] Through the above technical solution, the function of the support ring 1 is to connect the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2.

[0016] Furthermore, a second support ring is provided between the first optical fiber rotating bracket and the second optical fiber rotating bracket, and the second support ring is located in the middle section of the long sides of the first optical fiber rotating bracket and the second optical fiber rotating bracket.

[0017] Through the above technical solution, the function of the support ring 2 is to provide support for the middle section of the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2, and to protect the driven gear.

[0018] Furthermore, the bottoms of the optical fiber rotating bracket 1 and the optical fiber rotating bracket 2 are fixed on a bottom plate, and the bottom plate is suitable for connecting to a workpiece plate of a coating machine.

[0019] Through the above technical solution, the function of the bottom plate is to firmly mount the rotating mechanism as a whole on the coating machine.

[0020] Compared with the prior art, the beneficial effects achieved by this application are: The present application clamps the optical fiber through a rotating mechanism and drives the optical fiber to rotate, so that the outer diameter of the optical fiber can be evenly coated, thereby improving the coating quality of the optical fiber; The present application clamps the middle section of the optical fiber to drive the midpoint section to rotate, thereby driving the two ends of the optical fiber to rotate, thereby fundamentally preventing the optical fiber from breaking during the coating process; The present application can drive multiple optical fibers to rotate at one time for uniform coating, thereby improving coating efficiency and uniformity of the film layer.

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Example 1

[0025] like Figure 1-2As shown, an optical fiber rotating mechanism comprises an optical fiber rotating bracket 11, an optical fiber rotating bracket 2 12 and a bottom plate 13. The bottoms of the optical fiber rotating bracket 11 and the optical fiber rotating bracket 2 12 are fixed together on a bottom plate 13, and the bottom plate 13 is connected to the workpiece plate of the coating machine, so that the rotating mechanism 1 can be firmly installed in the coating machine.

[0026] Based on the above, a support ring 14 and a support ring 2 15 are provided between the optical fiber rotating bracket 1 11 and the optical fiber rotating bracket 2 12. One end of the support ring 14 is connected to the optical fiber rotating bracket 1 11 by bolts, and the other end is connected to the optical fiber rotating bracket 2 12 by bolts. The support ring 14 is installed on the four corners of the optical fiber rotating bracket 1 11 and the optical fiber rotating bracket 2 12 to play a connecting role. One end of the support ring 2 15 is connected to the middle section of the long side of the optical fiber rotating bracket 1 11 by bolts, and the other end is connected to the middle section of the long side of the optical fiber rotating bracket 2 12 by bolts. The support ring 2 15 plays a role of strengthening support.

[0027] Based on the above, the wall surface of the optical fiber rotating bracket 11 is provided with at least one through hole 111, and the wall surface of the optical fiber rotating bracket 2 12 is provided with at least one through hole 2 121. The center of the circle of through hole 111 and the center of the circle of through hole 2 121 are located on the same straight line. Specifically, there are eleven through holes 111 and eleven through holes 121. Among them, ten through holes 111 and through holes 2 121 are suitable for the passage of the hollow tube 16, and the outer sleeve of the hollow tube 16 is provided with a driven gear 19, and the driven gear 19 is bonded to the hollow tube 16, and the gears of adjacent driven gears 19 are meshed with each other, and the interior of the hollow tube 16 is for the optical fiber to pass through and be fixed with the optical fiber. The remaining pair of through holes 111 and through holes 2 121 are for the connection shaft 17 to pass through. For example, in this embodiment, the connection shaft 17 is installed at the end of the rotating mechanism 1. The connecting shaft 17 is connected to the transmission shaft of the coating machine, and a driving gear 18 is disposed outside the connecting shaft 17, and the gear of the driving gear 18 is meshed with the gear of the driven gear 19. When the transmission shaft of the coating machine rotates, the connecting shaft 17 is driven to rotate, thereby driving the driving gear 18 and the driven gear 19 to rotate.

[0028] Based on practical applications, the opposite surfaces of the optical fiber rotating bracket 11 and the optical fiber rotating bracket 2 12 are provided with grooves 112, bearings 113 and gaskets 114. A bearing 113 is provided in the groove 112, and a gasket 114 is provided on the side of the bearing 113 away from the groove 112. The diameter of the gasket 113 is smaller than the diameter of the bearing 113, thereby reducing the side friction. The two ends of the driven gear 19 are respectively arranged on the gasket 114 of the hollow tube 16. The two ends of the driving gear 18 are respectively arranged on the gasket 114 of the connecting shaft 17. The function of the bearing 113 is to isolate the movement force of the driven gear 19 or the driving gear 18 from being transmitted to the optical fiber rotating bracket 11 or the optical fiber rotating bracket 2 12. The function of the gasket 114 is to isolate the rotational force of the driven gear 19 from the bearing 113, thereby reducing the metal wear of the driven gear 19 and protecting the driven gear 19.

[0029] Based on practical applications, the hollow tube 16 is used to fix the middle section of the optical fiber. Specifically, an optical fiber is passed through the hollow tube 16, and when it reaches the middle section, it stops, and the hollow tube 16 and the optical fiber are fixedly connected by tape and clamps. In this way, when the hollow tube 16 rotates, the middle section of the optical fiber also rotates, driving the two ends of the optical fiber to rotate at the same time. When replacement is required, the tape and clamp can be removed. There are ten hollow tubes 16 in this embodiment, and ten optical fibers can be passed through at the same time.

[0030] The implementation process of this embodiment is as follows: during installation, the connecting shaft 17 of the rotating mechanism 1 is connected to the transmission shaft of the coating machine, and the bottom plate 13 of the rotating mechanism 1 is fixed to the workpiece plate of the coating machine by bolts, so that the rotating mechanism 1 is fixed inside the coating machine. When started, the coating machine works, the transmission shaft rotates to drive the connecting shaft 17 to rotate, thereby driving the driving gear 18 and the driven gear 19 to rotate, and then the middle section of all optical fibers is driven to rotate, and then the two ends of the optical fiber are also driven to rotate. The optical fiber is uniformly coated while rotating, avoiding the breakage of the optical fiber, reducing the material cost, and greatly improving the coating quality and uniformity of the film layer, and also improving the work efficiency.

[0031] For a coating machine of ordinary specifications, the method of this embodiment is used to fix the optical fiber, and an optical fiber of up to about 3 meters can be fixed for self-rotation coating.

[0032] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present application. Any mark in a claim should not be regarded as limiting the claim involved.
