The terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated, that is, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In addition, unless otherwise specified, "multiple" means two or more.

[0029] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] like Figure 1-6 As shown, in the optical fiber stripping device provided by the embodiment of the present invention, the optical fiber includes a sheath and a fiber core arranged in the sheath, and the optical fiber stripping device includes a body 1, a wire clamping assembly 2 and a wire cutting assembly 3. The wire clamping assembly 2 is used to clamp or loosen one end of the optical fiber, and the wire cutting assembly 3 is used to cut the sheath of the optical fiber.

[0031] In this embodiment, the wire clamping assembly 2 includes a positioning block 21, a movable block 22 and a first driving body 23. The positioning block 21 is installed on the body 1. The first driving body 23 is configured to drive the movable block 22 so that the movable block 22 and the positioning block 21 switch between a snap-fit ​​state and a separated state. When in the snap-fit ​​state, the positioning block 21 and the movable block 22 snap together to form a wire clamping hole 24, and the wire clamping hole 24 is used to clamp the optical fiber. When in the separated state, the movable block 22 and the positioning block 21 are separated from each other.

[0032] In this embodiment, the cutting assembly 3 is arranged on the machine body 1, and is configured to be able to move in the direction away from or close to the clamping assembly 2 along the axial direction of the clamping hole 24, and the cutting assembly 3 includes a second driving body 32 and two groups of cutters 31 with cutting grooves 311 at the blades, and the second driving body 32 is configured to drive the two groups of cutters 31 to switch between the abutting state and the separated state. When in the abutting state, the cutting grooves 311 of the two groups of cutters 31 are combined into a cutting hole for cutting the sheath of the optical fiber passing therethrough, and when in the separated state, the two groups of cutters 31 are separated from each other.

[0033] In this embodiment, the axis of the optical fiber, the axis of the clamping hole 24 and the axis of the cutting hole coincide with each other, which is conducive to clamping the optical fiber in a straight line and cutting off and removing the sheath.

[0034] During operation, the first driving body 23 is started to drive the positioning block 21 to move, so that the movable block 22 is in a separated state from the positioning block 21. At this time, the optical fiber is placed between the movable block 22 and the positioning block 21, and the second driving body 23 is started to clamp the optical fiber through the clamping hole 24 between the movable block 22 and the positioning block 21; one end of the optical fiber is passed through the two groups of cutters 31 of the cutting assembly 3, and the second driving body 32 is started to make the two groups of cutters 31 approach each other and be in abutment. At this time, the cutting grooves 311 of the two cutters 31 are combined into a cutting hole to surround the sheath of the cut optical fiber to avoid damaging the fiber core; the cutting assembly 3 is moved in a direction away from the clamping assembly 2. Since the two cutters 31 are in abutment, they can clamp the cut sheath, and when the cutter 31 moves along the axial direction of the optical fiber, the sheath of the optical fiber can be stripped from the fiber core.

[0035] Based on the above structural setting, the optical fiber stripping device can avoid damaging the fiber core during operation and has high stripping efficiency.

[0036] In one embodiment, the diameter of the cut hole is larger than the inner diameter of the sheath and smaller than the outer diameter of the sheath. By limiting the size of the cut hole, only a portion of the sheath thickness can be cut during the stripping operation, so that the blade of the cutter 31 will not directly contact the fiber core in the sheath, thereby avoiding damage to the fiber core in the sheath. In addition, the blade of the cutter 31 will hold the partially cut sheath, and the cutter 31 can strip the sheath of the optical fiber from the fiber core during the axial movement of the optical fiber.

[0037] like Figure 3 As shown, in one embodiment, the clamping assembly 2 further includes a transmission block 25 and two transmission rods 26, the movable block 22, the positioning block 21, the transmission block 25 and the first driving body 23 are arranged from top to bottom in sequence, the positioning block 21 is fixed on the machine body 1, the first driving body 23 is installed in the machine body, the power output end of the first driving body 23 is connected to the first end of the transmission rod 26 through the transmission block 25, and the second end of the transmission rod 26 moves upward through the positioning block 21 and is fixedly connected to the movable block 22. When working, the first driving body 23 is started to drive the transmission rod 26 to move downward through the transmission block 25, and further makes the movable block 22 approach or move away from the positioning block 21, so as to clamp or loosen the optical fiber, so that the transmission block 25 cooperates with the two transmission rods 26 to transmit, so that the movable block 22 can move smoothly.

[0038] Furthermore, the clamping assembly 2 further includes two linear bearings 27, which are arranged on the side of the positioning block 21 away from the movable block 22, and the linear bearings 27 are detachably connected to the positioning block 21, and the two transmission rods 26 pass through the two linear bearings 27 in a one-to-one correspondence. The linear bearings 27 can keep the transmission rods 26 moving smoothly.

[0039] like Figure 1 and 2As shown, the machine body 1 includes a housing 11, a first slide rail 12 installed in the housing 11, and a mounting frame 13. The mounting frame 13 includes a bottom plate 131 and a frame 132 vertically arranged on the bottom plate 131. The bottom plate 131 is slidably mounted on the first slide rail 12. Figure 4 As shown, two groups of second driving bodies 32 are provided, and the two groups of second driving bodies 32 are correspondingly arranged at the upper and lower ends of the frame 132, and the power output ends of the two groups of second driving bodies 32 are connected to the two groups of cutters 31 in a one-to-one correspondence. When working, the two groups of second driving bodies 32 drive the two groups of cutters 31 to abut against each other or move away from each other, so as to achieve precise control of the position between the two groups of cutters 31.

[0040] Specifically, the body 1 further includes a third driving body 14, which is installed in the housing 11, and a power output end of the third driving body 14 is connected to the bottom plate 131. The third driving body 14 drives the mounting frame 13 to move on the first slide rail 12, so that the sheath of the optical fiber can be further stripped when the sheath is cut by the cutter 31.

[0041] Exemplarily, the first driving body 23 , the second driving body 32 and the third driving body 14 are all cylinders.

[0042] like Figure 2 and 6 As shown, the machine body 1 also includes a threading block 15 with a threading hole 151. The threading block 15 is arranged on the bottom plate 131, and the threading block 15 is located on the side of the cutter 31 away from the clamping assembly 2. The axis of the threading hole 151 coincides with the axis of the cutting hole. The threading block 15 is configured to allow one end of the optical fiber to pass through the threading hole 151. During operation, the threading hole 151 is used to allow one end of the optical fiber to pass through, and ensure that the optical fiber has friction in the threading hole 151. When the third driving body 14 drives the threading block 15 on the mounting frame 13 to move in a direction away from the clamping assembly 2, the sheath of the optical fiber is stripped from the fiber core. At this time, it is not necessary to make the two cutters 31 in abutment state to ensure that the sheath of the optical fiber is stripped from the fiber core, further avoiding damage to the fiber core.

[0043] Specifically, the threading hole 151 includes a tapered hole section 151a and a round hole section 151b connected to an end of the tapered hole section 151a with a smaller inner diameter, and the optical fiber passes through the tapered hole section 151a and the round hole section 151b in sequence. The above structure facilitates the optical fiber to pass through the threading hole 151, and a thin steel wire can be tied to one end of the optical fiber to drive the optical fiber to pass through the threading hole 151 together with the thin steel wire.

[0044] like Figure 4As shown, in one embodiment, it also includes two sets of second slide rails 33 distributed longitudinally and two sets of tool holders 34 distributed transversely, the two sets of second slide rails 33 are respectively arranged on the left and right sides of the frame 132, one set of tool holders 34 are slidably installed on the upper part of the two sets of second slide rails 33, and the other set of tool holders 34 are slidably installed on the lower part of the two sets of second slide rails 33, and the two sets of cutters 31 are installed in the middle part of the two sets of tool holders 34 in a one-to-one correspondence, and the power output ends of the two sets of second driving bodies 32 are connected to the two sets of tool holders 34 in a one-to-one correspondence. When in use, the second driving body 32 is started to drive the tool holder 34 to move smoothly on the second slide rail 33, and further the cutter 31 runs smoothly during the movement.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
