Technical Field

[0001] The utility model relates to the technical field of optical fiber detection, in particular to a device for testing the stripping force of an optical fiber coating. Background Art

[0002] An optical fiber is the abbreviation of an optical waveguide fiber, which is a fiber made of glass or plastic and can be used as an optical conduction tool. During the production of optical fibers, in order to provide effective protection, a coating is wrapped around the outside of the optical fiber, and a buffer layer of the optical waveguide fiber is formed after curing. Currently, common optical fiber coatings mainly include molybdenum and silicon nitride, etc.

[0003] After the optical fiber coating is wrapped, a series of tests need to be carried out on the optical fiber coating, including the test item of the stripping force of the optical fiber coating. However, during the current stripping force test, the optical fiber cannot be kept straight during the clamping of the optical fiber, and only the coating is peeled off in a single direction. During the process of pulling the coating by an external force, the optical fiber is prone to bending, and the external force applied by the device cannot be completely used for the separation effect between the coating and the fiber core, resulting in deviation of the test result. At the same time, most of the current coating stripping methods are to cut a section of the coating at one end of the optical fiber, and then use the device to clamp the protruding corner of the coating and pull it. In this way, the coating is unevenly stressed, and the coating is more torn at the edge, making it easier for the coating to separate from the fiber core, and the endurance of the entire coating cannot be accurately detected.

[0004] Therefore, it is necessary to provide a new device for testing the stripping force of an optical fiber coating to solve the above technical problems. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a device for testing the stripping force of an optical fiber coating with convenient operation and improved detection accuracy.

[0006] To solve the above technical problems, the device for testing the stripping force of an optical fiber coating provided by the utility model includes: an operation table and two support frames fixedly installed on the top of the operation table. Two sliding frames are slidably installed on the top of the operation table, and fixing frames are fixedly installed on the tops of the two sliding frames. Stripping mechanisms are arranged on the two fixing frames.

[0007] Preferably, a placement groove is formed on any one of the support frames. A threaded cylinder is rotatably installed on the top of the support frame. A threaded rod is threadedly installed on the inner wall of the threaded cylinder. A lifting plate is slidably installed in the support frame.

[0012] Compared with the related art, the optical fiber coating peeling force testing device provided by the present utility model has the following beneficial effects:

[0013] The present utility model provides an optical fiber coating peeling force testing device. During the process of detecting the peeling force of the optical fiber, in this application, by clamping and fixing both ends of the optical fiber simultaneously, the optical fiber is always in a straightened state during the detection process.

[0026] A chamber 12 is formed in the operating table 1. Both of the sliding frames 15 are slidably installed in the chamber 12. A strip-shaped hole connecting the chamber 12 is formed at the top of the operating table 1. The tops of both of the sliding frames 15 extend above the operating table 1 through the strip-shaped hole. A cylinder 13 is fixedly installed on the outer wall of one side of the operating table 1. The output shaft of the cylinder 13 extends into the chamber 12. The cylinder 13 is equipped with a pressure regulating system. A push plate 14 is fixedly installed on the output shaft of the cylinder 13. Hinge plates 16 are respectively connected between the push plate 14 and both of the sliding frames 15. Two sliding rods are fixedly installed on the inner walls of both sides of the chamber 12. Both of the sliding rods penetrate through both of the sliding frames 15 and are slidably connected thereto.

[0027] Any one of the peeling mechanisms includes an elastic plate 18. The elastic plate 18 is slidably installed on the inner walls of both sides of the fixed frame 17.

[0029] The working principle of the optical fiber coating stripping force testing device provided by the utility model is as follows:

[0030] During the stripping force test of the optical fiber, the staff can first place the two ends of the optical fiber in the placement grooves 3 on the two support frames 2 respectively, and the optical fiber is located between the two conflicting blades 20 and the two conflicting blades 22, and the coating of the optical fiber is cut by the conflicting blades 20 and 22, so that the conflicting blades 20 and 22 are attached to the fiber core under the effect of the spring 19 and the compression spring, and the semicircular conflicting blades 20 and 22 are embedded in the cut coating, and the excess two ends of the optical fiber can extend to the outside through the avoidance grooves on the two support frames 2.

[0031] After the optical fiber is pulled to a straight state, the connecting rod 10 can be rotated. The rotation of the connecting rod 10 will drive the two active bevel teeth 11 to rotate, thereby driving the two driven bevel teeth 9 and the two threaded barrels 7 to rotate. During the rotation of the threaded barrel 7, since the two lifting plates 5 are both limited, the two lifting plates 5 and the two threaded rods 8 cannot rotate with the threaded barrel 7, and can only keep moving downward under the side effect of the thread, and finally press the optical fiber in place, so that the optical fiber is always in a straight state.

[0032] Subsequently, the staff can start the cylinder 13 and make the cylinder 13 move horizontally with a certain pressure. After the cylinder 13 is started, the horizontal movement of the output shaft will drive the push pressing plate 14 to move horizontally, so that the two hinge plates 16 respectively prop against the sliding frames 15 on both sides. At this time, the pressure of the cylinder 13 directly acts on the coating layer of the optical fiber through the two contact blades one 20 and the two contact blades two 22. By increasing the pressure of the cylinder 13, the coating layer is finally separated from the glass on the fiber core to detect the peeling force of the optical fiber.

[0033] Compared with the related technologies, the optical fiber coating peeling force testing device provided by the present utility model has the following beneficial effects:

[0034] The present utility model provides an optical fiber coating peeling force testing device. During the detection of the peeling force of the optical fiber, the application simultaneously clamps and fixes both ends of the optical fiber, so that the optical fiber is always in a straightened state during the detection. At the same time, the two contact blades one 20 and the two contact blades two 22 cut into the coating layer of the optical fiber and abut against the fiber core. After the cylinder 13 operates, the pressure of the push pressing plate 14 directly acts on the coating layer. By adjusting the pressure of the cylinder 13, the peeling force of the optical fiber coating is finally detected. The whole process is not only simple and convenient, but also compared with the traditional method, it avoids the bending of the optical fiber during the detection and reduces the tearing of the coating during the peeling. By adopting the direct contact method, the acting force directly acts on the stress points of the entire optical fiber coating, which improves the detection accuracy to a certain extent.
