As the main medium for light transmission, the quality of optical fiber directly affects the quality of optical fiber communication. The coating is mainly used to protect the fiber core, and the protection of the coating on the fiber core mainly depends on the stripping force between the coating and the fiber core. Therefore, effective monitoring of the coating stripping force can effectively evaluate the quality of the optical fiber, so an optical fiber coating stripping force tester is needed.

[0003] For example, the utility model application number CN202223445903.X discloses a fiber coating stripping force testing device. However, the testing machine similar to the above application currently has the following shortcomings: by fixing one end of the optical fiber, clamping the other end of the optical fiber with two opposing blades, and moving the two blades at the same time to strip the coating, since the relative positions of the two blades cannot be uniformly determined, the measured data is not accurate enough, and it is not convenient to fully tighten and clamp optical fibers of different thicknesses.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a limited clamping optical fiber coating stripping force testing machine is proposed. Utility Model Content

[0023] The specific operation is as follows: the driving motor 5 is used to drive the rotation of the screw rod 601, which in turn can drive the movement of the movable sleeve 602, the connecting block 603, and the fixed plate 604, so that the optical fiber clamp assembly 7 on one side of the fixed plate 604 can drive the clamped optical fiber to move, so that a certain peeling force is generated between the optical fiber core and the surface coating, thereby realizing the optical fiber coating peeling force test.

A limiting slide 702 is provided on the inner side of the mounting plate 701, and two upper and lower arc-shaped slides 703 are slidably installed on one side of the limiting slide 702 through a slider. The outer wall of the arc-shaped slide 703 is fixed with a tooth block 704, and a clamp 705 is fixed on one side of the arc-shaped slide 703. The inner side of one end of the clamp 705 A jaw 706 is provided, and the inner ring of the jaw 706 is adhered with an anti-slip layer. Active gears 708 are installed on the upper and lower sides of the mounting plate 701 via a motor shaft 707, and the active gears 708 are meshed with the tooth blocks 704 of the arc-shaped slide 703. The optical fiber clamp assembly 7 also includes a rotating shaft 709, which is provided at the junction of the upper and lower clamps 705.

[0025] The specific operation is as follows: the built-in motor of the mounting plate 701 is used to drive the rotation of the motor shaft 707 and the driving gear 708, and the driving gear 708 is meshed with the tooth block 704 of the arc-shaped slide 703, so that the arc-shaped slide 703 can slide in the limiting slide groove 702 of the mounting plate 701 with the rotating shaft 709 as a circle, thereby driving the rotation of the upper and lower clamps 705, so that the jaws 706 of the clamps 705 can clamp one end of the optical fiber, which is suitable for optical fibers of different thicknesses, and the inner circle of the jaws 706 is pasted with an anti-slip layer to increase friction and play an anti-slip role, so as to cooperate with the mobile stripping component 6 to perform optical fiber coating stripping force testing.

[0026] Figure 1 、 Figure 3-Figure 4 As shown, a fiber core clamp assembly 8 is installed above the lifting plate 2, and the fiber core clamp assembly 8 has the same structure as the optical fiber clamp assembly 7. One side of the fiber core clamp assembly 8 is connected to a limited reinforcement assembly 9; the limited reinforcement assembly 9 includes a connecting rod 901, a bottom frame 902 and an upper plate 903. The bottom frame 902 is fixed to one side of the connecting rod 901, and the bottom surface of the bottom frame 902 is an arc-shaped structure, and the upper plate 903 is fixed above the bottom frame 902; the limited reinforcement assembly 9 also includes a micro telescopic rod 904, a positioning splint 905 and a rubber layer 906. The micro telescopic rod 904 is installed on the lower middle side of the upper plate 903, and a positioning splint 905 is fixed to the bottom of the micro telescopic rod 904. The positioning splint 905 is an arc-shaped structure, and the inner side of the positioning splint 905 is bonded with a rubber layer 906;

[0027] The specific operation is as follows: the fiber core clamp assembly 8 is used to clamp the exposed core of the optical fiber with part of the coating stripped off. The position of the positioning clamp 905 is easily adjusted by telescopic means through the micro telescopic rod 904. The rubber layer 906 on the inner side of the positioning clamp 905 can increase the friction force, so that the arc-shaped positioning clamp 905 cooperates with the bottom frame 902 below to further limit and clamp one end of the fiber core, thereby improving the clamping stability.

[0028] In summary, if Figures 1-4As shown, the optical fiber coating stripping force tester with limited clamping, when in use, can first clamp the coated end of the optical fiber in the position of the optical fiber clamp assembly 7, first make the optical fiber pass through the jaws 706 of the two clamps 705, and then drive the motor shaft 707 and the driving gear 708 to rotate through the built-in motor of the mounting plate 701, thereby driving the arc-shaped slide plate 703 to slide in the limited sliding groove 702 of the mounting plate 701 with the rotating shaft 709 as a circle, and then drive the rotation of the upper and lower clamps 705, so that the jaws 706 of the clamp 705 can clamp one end of the optical fiber. At this time, the inner circle of the jaws 706 is pasted with an anti-slip layer to increase the friction and play an anti-slip role. Then, similarly, the bare core of the other end of the optical fiber with part of the coating stripped off is clamped through the fiber core clamp assembly 8. The micro telescopic rod 904 can be used to adjust the position of the positioning clamp 905. At this time, the rubber layer 906 on the inner side of the positioning clamp 905 can increase the friction force, so that the arc-shaped positioning clamp 905 cooperates with the bottom frame 902 below to further limit and clamp one end of the fiber core, thereby improving the clamping stability. During the test, the driving motor 5 drives the rotation of the screw rod 601, which can then drive the movement of the movable sleeve 602, the connecting block 603, and the fixed plate 604, so that the optical fiber clamp assembly 7 on one side of the fixed plate 604 can drive the clamped optical fiber to move, so that a certain peeling force is generated between the optical fiber core and the surface coating, thereby realizing the optical fiber coating peeling force test, thus completing the use process of the optical fiber coating peeling force testing machine with limited clamping.
