Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] To achieve the above objectives, the technical solution of this utility model is as follows:

[0030] See Figures 1-5 As shown, this embodiment provides a circumferential cutting mechanism, including:

[0031] Rack 1;

[0032] Positioning module 2 for fixing optical fiber 7;

[0033] Guiding module 3 is used to guide optical fiber 7;

[0034] Ring-cutting module 4 for cutting the outer sheath of optical fiber 7;

[0035] Linear moving module 5 used to drive the ring cutting module 4 to move;

[0036] Positioning module 2, guide module 3, and linear motion module 5 are all mounted on frame 1, and circumferential cutting module 4 is mounted on linear motion module 5. Positioning module 2, guide module 3, and circumferential cutting module 4 are arranged opposite to each other.

[0037] Furthermore, the positioning module 2 includes a turntable 21, which is mounted on the frame 1 and has several positioning grippers 22 for holding and fixing the optical fiber 7.

[0038] Furthermore, several positioning grippers 22 are set at equal intervals.

[0039] Furthermore, the guide module 3 includes a guide support frame 31, a guide mounting plate 32, a guide cylinder 33, a first guide gripper 34, and a second guide gripper 35. The guide support frame 31 is fixed on the frame 1, the guide mounting plate 32 is fixed on the guide support frame 31, the guide cylinder 33 and the second guide gripper 35 are fixed on the guide mounting plate 32, the second guide gripper 35 is connected to the output end of the guide cylinder 33, and the first guide gripper 34 and the second guide gripper 35 surround each other to form a guide groove 36.

[0040] In this application, the guide cylinder 33 can drive the second guide gripper 35 to approach or move away from the first guide gripper 34, thereby opening and closing the guide groove 36. When the guide groove 36 is open, it is convenient to put the optical fiber 7 into the guide groove 36. When it is closed, it is convenient to take out the optical fiber 7.

[0041] Furthermore, the circumferential cutting module 4 includes a circumferential cutting cylinder 41, a first circumferential cutting gripper 42, and a second circumferential cutting gripper 43. The circumferential cutting cylinder 41 is mounted on the linear motion module 5. The first circumferential cutting gripper 42 and the second circumferential cutting gripper 43 are both mounted on the output end of the circumferential cutting cylinder 41 and can move horizontally towards each other or away from each other under the drive of the circumferential cutting cylinder 41. A first circumferential cutting blade 44 is mounted on the first circumferential cutting gripper 42, and a second circumferential cutting blade 45 is mounted on the second circumferential cutting gripper 43. A circumferential cutting groove 46 is formed between the first circumferential cutting blade 44 and the second circumferential cutting blade 45. In this application, when the worker places the fiber 7 onto the positioning module 2 and the guide module 3, the front end of the fiber 7 extends into the circumferential cutting groove 46. After the circumferential cutting module 4 moves back and forth to adjust the cutting length, the circumferential cutting cylinder 41 drives the first circumferential cutting claw 42 and the second circumferential cutting claw 43 to move slowly towards each other. The first circumferential cutting blade 44 and the second circumferential cutting blade 45 clamp the fiber 7, reducing the circumferential cutting groove 46 and cutting the outer sheath of the fiber 7. After cutting to a certain depth, the linear motion module 5 drives the circumferential cutting module 4 to move, breaking the outer sheath of the fiber 7. Then, the circumferential cutting cylinder 41 drives the first circumferential cutting claw 42 and the second circumferential cutting claw 43 to move in opposite directions, dropping the stripped outer sheath of the fiber 7 into the waste collection trough 6 below. At the same time, since the first circumferential cutting claw 42 and the second circumferential cutting claw 43 can move slowly back and forth under the drive of the circumferential cutting cylinder 41, the outer sheath of the fiber 7 is slowly circumferentially cut, thereby avoiding damage to the fiber 7.

[0042] Furthermore, the circumferential cutting module 4 also includes a first guide rod 47 and a second guide rod 48. The first guide rod 47 is fixed to the first circumferential cutting gripper 42, and the second guide rod 48 is fixed to the second circumferential cutting gripper 43. Both the first guide rod 47 and the second guide rod 48 are provided with opposing semicircular grooves 49. During the circumferential cutting of the optical fiber 7, the first guide rod 47 and the second guide rod 48 can move towards each other along with the first circumferential cutting gripper 42 and the second circumferential cutting gripper 43, so that the two semicircular grooves 49 close into a complete circular groove, guiding and limiting the optical fiber 7, and improving the stability of the circumferential cutting.

[0043] Furthermore, an air pipe mounting plate 8 is also installed on the circumferential cutting cylinder 41, and an air blowing pipe 9 is mounted on the air pipe mounting plate 8. The air blowing pipe 9 is positioned directly above the first circumferential cutting jaw 42 and the second circumferential cutting jaw 43. An external air source can be connected to the air pipe. When the outer sheath of the optical fiber 7 is cut, air is blown downwards through the air pipe to blow the outer sheath waste into the waste collection tank 6 below.

[0044] Furthermore, the linear motion module 5 includes a lead screw motor 51, a lead screw nut seat 52, a connecting plate 53, a slider 54, and a slide rail 55. The lead screw motor 51 and the slide rail 55 are both mounted on the frame 1. The lead screw nut seat 52 is connected to the lead screw of the lead screw motor 51. One end of the connecting plate 53 is connected to the lead screw nut seat 52, and the other end is connected to the ring cutting cylinder 41. The lead screw nut seat 52 is slidably connected to the slide rail 55 through the slider 54.

[0045] Furthermore, a waste collection trough 6 is also installed on the frame 1, which is located below the first ring cutting jaw 42 and the second ring cutting jaw 43.

[0046] The process of stripping the outer sheath of optical fiber 7 in the ring-cutting mechanism of this application is as follows:

[0047] 1. The staff manually fixes the optical fiber 7 onto the positioning module 2 and guides and fixes it through the guide module 3. The end of the optical fiber 7 enters the ring cutting module 4.

[0048] 2. The linear moving module 5 drives the ring cutting module 4 to move, adjusting the peeling length;

[0049] 3. The ring-cutting module 4 operates to cut the outer sheath of the optical fiber 7;

[0050] 4. The linear moving module 5 drives the ring cutting module 4 to move backward, tearing off the outer sheath of the optical fiber 7.

[0051] 5. The air blowing pipe 9 blows air to blow the stripped outer sheath of the optical fiber 7 into the outer sheath waste collection tank 6 below.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
