Description

Technical Field

[0001] The invention belongs to the technical field of optical fiber processing, and in particular relates to a fiber stripping device with cleaning function. Background Art

[0002] Fiber coating stripping is an important step in fiber processing, involving a variety of technical means. The main methods for stripping fiber coating are:

[0003] Manual stripping method: Manual stripping is a traditional stripping method, which usually uses a blade or special tools to manually strip the coating of the optical fiber. This method is simple to operate, but it is easy to damage the optical fiber, and the stripping effect is not consistent, and it is not easy to accurately control the stripping length.

[0004] Automatic stripping method: Automatic stripping method uses mechanical equipment for stripping, which can accurately control the stripping length and reduce the error and damage caused by manual operation. However, this method also has the risk of cutting edge damage to the optical fiber, and the equipment operation is relatively complex and the maintenance frequency is high.

[0005] Chemical stripping method: Chemical stripping method uses chemical solvents to dissolve the coating of optical fiber. This method can quickly remove the coating, but it is easy to cause environmental pollution and has certain risks. In addition, chemical stripping method may damage the surface of optical fiber, affecting the service life and performance of optical fiber.

[0006] Laser stripping: Laser stripping is an emerging stripping technology that uses a laser beam to irradiate the optical fiber coating, causing it to evaporate or decompose instantly, thereby achieving the purpose of stripping. Laser stripping has the advantages of being non-contact, fast, and precise, and in theory it can avoid damaging the optical fiber. However, laser stripping technology is not yet fully mature and still faces some challenges in practical applications.

[0007] Therefore, various methods have great limitations. For mechanical stripping, a common solution is that the optical fiber coating stripping device fixes the optical fiber through an optical fiber fixing device, and drives the optical fiber to rotate around the rotation axis and move along the extension direction of the rotation axis to strip the coating in a spiral manner. However, this stripping method is difficult to strip completely, especially for the continuous stripping of the coating of rolled optical fibers. This method is difficult to complete the operation quickly and efficiently, and the generated shavings are difficult to clean up. Summary of the invention

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In order to illustrate the technical solution of the present invention, a specific embodiment is provided below for illustration.

[0027] like Figure 1 , 2 As shown, this embodiment provides a fiber stripping device with cleaning, including a liquid-chip recovery box 1, in which a left cutter head assembly 2 is fixed, a driving cylinder 3 is installed on the liquid-chip recovery box 1, a right cutter head assembly 4 is arranged on the output shaft of the driving cylinder 3, and the right cutter head assembly 4 is located in the liquid-chip recovery box 1, and the two cutter head assemblies are arranged opposite to each other. Both cutter head assemblies include a seat body 51, a sink 52 is provided at the front end of the seat body 51, and a cutter head module 6 is locked in the sink 52, wherein at least one seat body 51 is provided with a gas interface 53 and an alcohol pumping interface 54, and both interfaces are connected to the corresponding cutter head module 6 through an internal channel. In addition, the side wall of the driving cylinder 3 also has a guide rail 31, and an L-shaped plate 32 is installed on the guide rail 31, wherein the seat body of one cutter head assembly is fixedly connected to the L-shaped plate 32, and the driving cylinder drives the left cutter head assembly to move more stably.

[0028] This device is installed on a linear module. Specifically, the bottom of one side of the liquid-chip recovery box is fixed on the linear module to realize the reciprocating movement of the driving device. After the optical fiber is released from the reel, it is led out from between the two cutter head assemblies, wherein the left cutter head assembly is fixed in position, and the right cutter head assembly is closed with the left cutter head assembly under the drive of the driving cylinder. The cutter head module of the cutter head assembly contacts the surface of the optical fiber, and the optical fiber coating is stripped by reciprocating movement. Before stripping, the gas interface is connected to the nitrogen source, and the pumping alcohol interface is connected to the alcohol barrel. During stripping, alcohol is injected into the pumping alcohol interface, and under the pneumatic drive of the high-pressure nitrogen source, the alcohol and gas are sprayed toward the optical fiber position together. Therefore, the stripping surface can be cleaned while stripping the coating layer, and the stripping scraps are flushed into the liquid-chip recovery box. With alcohol wetting the optical fiber surface, the stripping process is smoother.

[0029] In this structure, there are two cutter head assemblies on the left, and at least one of the cutter head assemblies has a gas interface and an alcohol pumping interface on the base body. As a specific example, in this embodiment, the base body on the left cutter head assembly has two interfaces, and the base body on the right cutter head assembly has only a gas interface. By spraying alcohol and gas on one side and only spraying gas on the other side, a better effect can also be achieved.

[0030] In this embodiment, a pair of blade modules 6 are used to strip the coating of the optical fiber. Figure 4-7 As shown, the cutter head module 6 is composed of a front plate 61, a front blade 62, a rear blade 63, an overhead plate 64 and a rear plate 65 from front to back, wherein the sides of the front and rear blades are symmetrically provided with cutting edges 66, and the front and rear blades are provided with guide grooves 67 transversely along the cutting edges, the ends of the two guide grooves are connected, the guide groove on the rear blade 63 is connected with the overhead plate 64, the overhead plate 64 and the rear plate 65 are provided with air holes 68 and alcohol holes 69, and the gas interface 53 and the pumping alcohol interface 54 are correspondingly connected with the air holes 68 and the alcohol holes 69 through corresponding internal channels. In addition, the ends of the guide grooves of the front and rear blades are provided with circular holes 610, the two circular holes 610 are connected, and the alcohol hole 69 corresponds to the circular hole 610.

[0031] During operation, alcohol passes through the alcohol holes on the rear plate and the overhead plate, then enters the end of the guide groove of the rear blade and the front blade, and then follows the guide groove to the blade position. At the same time, nitrogen passes through the air holes on the rear plate and the overhead plate, and then also passes through the guide groove, and is sprayed toward the blade position along the guide groove. Therefore, the alcohol in the guide groove can be quickly taken out and sprayed out, so as to clean the optical fiber cladding and blow off the stripping debris. The liquid debris recovery box 1 is provided with a bottom opening 11 directly below the blade, and a bottom box 12 is provided at the bottom of the bottom opening 11. The bottom of the bottom box 12 is connected to a drainage port 13, and the liquid debris is discharged from the drainage port for easy collection.

[0032] In addition, in the present structure, a protrusion 611 is formed on the side of the front and rear blades of one of the cutter head modules, and a groove 612 is formed on the side of the front and rear blades of the other cutter head module. The protrusion 611 matches the shape of the groove 612 and is of the same height. When the two cutter head modules are closed, the protrusion can be aligned with the groove to form a limit, thereby ensuring the alignment accuracy. Moreover, an upper stop 613 is formed inwardly on the upper part of the front and rear plates of one of the cutter head modules, and a lower stop 614 is formed inwardly on the lower part of the front and rear plates of the other cutter head module. When the upper stop and the lower stop are close to each other and staggered, the blade edge position is left in the middle. The optical fiber is supported between the upper stop and the lower stop.

[0033] In summary, the fiber stripping device with cleaning function provided by the present invention realizes the stripping of the optical fiber coating by reciprocating the device on a linear module, which is better than the spiral stripping method. In addition, the fiber stripping device is provided with a gas interface and an alcohol pumping interface. Through the action of gas, alcohol is sprayed toward the blade position of the blade module. The stripping surface can be cleaned while stripping the coating, and the stripping debris is flushed into the liquid debris recovery box. The surface of the optical fiber is moistened with alcohol, and the stripping process is smoother.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
