Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber stripping equipment, and more particularly to an optical fiber fixed-length stripping equipment. Background Art

[0002] The optical fiber sheath wraps the multiple branch lines inside to form a whole line. When in use, the end needs to be stripped to form a bare optical fiber segment, or it needs to be stripped and recycled after recycling.

[0003] The prior art document CN213182114U provides a fixed-length fiber stripping device. The optical fiber is manually fixed to a fiber positioning fixture. An electron microscope is adjusted to a suitable position for visual observation via a three-axis fine-tuning slide. The electric slide is simultaneously adjusted to a specified position to precisely control the stripping length. Upon activation of a foot switch, the dual cutters close and sever the fiber end skin. Driven by the electric slide, the cutters then retreat, completing the automatic stripping operation. This device not only achieves semi-automatic stripping but also allows for precise adjustment of the stripping length. This device places one end of the optical fiber in a fixed position before stripping it with the cutter. Because the dual cutters are positioned relative to each other, they can only cut from opposite sides of the optical fiber, resulting in incomplete cutting. Furthermore, cutting from opposite sides can damage the internal branch lines, rendering the fiber unusable later. In view of this, we propose a fixed-length fiber stripping device.

[0042] The present invention will be further described in detail below with reference to the accompanying drawings, with reference to preferred embodiments of the present invention.

[0043] See also Figure 1-6 ,An optical fiber fixed-length stripping device, comprising:

[0044] Work box 1;

[0045] A fixed block 2 is fixedly arranged on the upper outer wall of the working box 1;

[0046] The stripping mechanism 3 includes a stripping block 4, a cutting knife is fixedly provided inside the stripping block 4, and the stripping block 4 is driven by rotation to perform circular cutting on the optical fiber;

[0047] The conveying assembly 5 includes a conveying block 6 and a conveying drive. The optical fiber is arranged inside the conveying block 6 and is conveyed in a fixed length by the conveying drive.

[0048] In this technical solution, the optical fiber is surrounded by the stripping block 4 and the opening and closing block 13. At this time, the stripping block 4 can perform a circular cutting action on the outer wall of the optical fiber, which not only achieves a thorough cutting of the optical fiber, but also avoids the occurrence of damage to the internal branch line of the optical fiber by the cutter, thereby ensuring the subsequent use of the optical fiber.

[0049] Specifically, the rotation drive includes a connecting shell 7 fixedly mounted on the rear outer wall of the fixed block 2. The rear end of the connecting shell 7 is provided with a mounting port, and a gear A8 is rotatably mounted on the front inner wall of the connecting shell 7. The side wall of the connecting shell 7 is provided with a central hole connected to the mounting port, and an arc-shaped shaft 11 is rotatably mounted on the inner wall of the central hole. The center of the peeling block 4 is provided with an arc-shaped slot, and the arc-shaped shaft 11 is fixedly sleeved on the inner wall of the arc-shaped slot. The arc-shaped shaft 11 coincides with the axis of the peeling block 4. The peeling block 4 is arranged in an arc-shaped structure, with the notch of the peeling block 4 connected to the circular slot. The side wall of the peeling block 4 is provided with evenly distributed gear teeth A9, which mesh with the gear A8.

[0050] In this technical solution, the rotation drive can drive the opening and closing block 13 to perform an opening and closing action relative to the peeling block 4.

[0051] Furthermore, a first motor 10 is fixedly installed inside the connecting shell 7, and an output shaft of the first motor 10 is coaxially connected and fixed to the gear A8.

[0052] Connecting grooves 12 are provided on the inner walls on both sides of the notch of the peeling block 4. An opening and closing block 13 with an arc-shaped structure is provided on the inner wall of one side of the connecting groove 12 through a pin shaft. The outer wall of the opening and closing block 13 is fixed with gear teeth B14, which are engaged with the gear A8.

[0053] Furthermore, when the opening and closing block 13 and the peeling block 4 form a closed cutting state, the peeling block 4 and the opening and closing block 13 are combined into a circular column structure, that is: the side wall of the peeling block 4 and the side wall of the opening and closing block 13 form a circular structure, and the inner wall of the arc shaft 11 and the inner wall of the opening and closing block 13 are also combined into a complete circular structure.

[0054] It is worth noting that a hinge seat 15 is fixedly provided on the inner wall of one side of the connecting groove 12 , and a telescopic rod 16 is rotatably provided on the hinge seat 15 , and the output end of the telescopic rod 16 is rotatably connected to the outer wall of the opening and closing block 13 .

[0055] In this technical solution, under the push of the telescopic rod 16, the opening and closing block 13 rotates around the pin shaft connected to the stripping block 4. When the optical fiber needs to be stripped, first, the telescopic rod 16 is used to control the opening and closing block 13 to open outward and place the optical fiber into the inner wall of the arc shaft 11. Then, the telescopic rod 16 is controlled to make the opening and closing block 13 and the stripping block 4 form a closed cutting state. At this time, the opening and closing block 13 and the stripping block 4 form a circular structure, and the first motor 10 is started. Driven by the gear A8, the opening and closing block 13 and the stripping block 4 rotate in the connecting shell 7 and complete the annular cutting of the optical fiber.

[0056] It is worth noting that two vertical blocks 17 are fixedly provided on the upper outer wall of the working box 1. The two vertical blocks 17 are symmetrically arranged on the left and right sides of the fixed block 2. A driving cavity is opened on the rear outer wall of each vertical block 17. Two worm gears 19 symmetrically arranged up and down are rotatably connected between the left and right inner walls of the driving cavity through a rotating shaft. The two worm gears 19 are meshed with a same worm 18. The front end of the worm 18 rotates forward and passes through the vertical block 17 to extend to the front side of the vertical block 17 and is fixedly connected to a handwheel 21.

[0057] The conveying block 6 includes two upper and lower parts with the same structure, which are combined to form a circular column structure. Swing rods 20 are fixed on the left and right sides of the worm gear 19 through a rotating shaft. The swing rod 20 on the upper side is fixedly connected to the upper structure of the conveying block 6, and the swing rod 20 on the lower side is fixedly connected to the lower structure of the conveying block 6.

[0058] In this technical solution, when the worm 19 is rotated by the handwheel 21, the upper and lower side swing rods 20 and the upper and lower structures of the conveying block 6 will be driven to rotate synchronously, thereby realizing the opening and closing of the upper and lower structures of the conveying block 6 to facilitate the placement and clamping of the optical fiber; in addition, by adjusting the opening and closing angles of the upper and lower structures of the conveying block 6, the clamping force of the optical fiber can be adjusted.

[0059] In addition, two symmetrically arranged cavities 22 are opened on the inner walls of the upper and lower structures of the conveying block 6. The conveying drive includes a conveying gear 23 that is rotatably arranged inside the cavity 22. The middle cross-section of the conveying gear 23 is a V-shaped structure. The conveying gear 23 is coaxially connected and fixed to a stepper motor 24 fixed inside the conveying block 6.

[0060] It should be noted that the midpoints of the two corresponding conveying gears 23 are located at the two ends of the vertical diameter of the inner hole of the conveying block 6 .

[0061] In this technical solution, the upper and lower conveying gears 23 clamp the optical fiber through the V-shaped structure in the middle. The teeth on the conveying gear 23 are in frictional contact with the outer surface of the optical fiber. Four stepper motors 24 respectively control the four conveying gears 23 to rotate synchronously to realize the conveyance of the optical fiber; at the same time, the fixed-length conveyance of the optical fiber can be achieved through the precise control of the four stepper motors 24.

[0062] In addition, an installation cavity is opened inside the working box 1, and a third motor 29 is fixedly installed on the inner wall of the installation cavity. A rotating block 25 is fixedly installed on the output shaft of the third motor 29. The outer wall of the rotating block 25 is rotatably connected to a connecting rod 26 near the edge through a pin shaft. A sliding groove is opened in the middle of the rear end of the working box 1, which passes through its upper side wall and rear side wall at the same time. A rocker rod 27 is rotatably connected inside the bottom of the sliding groove. The other end of the connecting rod 26 is rotatably connected to the middle and lower part of the rocker rod 27 through a pin shaft. The upper end of the rocker rod 27 extends through the sliding groove to the upper side of the working box 1 and is fixedly connected to a fixed column. The front end of the fixed column is connected to two symmetrically arranged L-shaped connecting columns, and the lower ends of the L-shaped connecting columns are fixedly connected to a guide cylinder 28.

[0063] In this technical solution, driven by the third motor 29, the guide cylinder 28 can drive the optical fiber to enter or exit the stripping mechanism.

[0064] It should be noted that when the guide cylinder 28 drives the optical fiber to enter the stripping mechanism, the axes of the inner hole of the guide cylinder 28, the arc-shaped through groove and the inner hole of the conveying block 6 coincide with each other.

[0065] When the optical fiber fixed-length stripping device is needed, first, the opening and closing block 13 is controlled to open outward by the telescopic rod 16, and the upper and lower structures of the conveying block 6 are controlled to be in the open state by rotating the hand wheel 21. Then, the optical fiber is placed in the guide cylinder 28 on the rocker 27, and the guide cylinder 28 is sent between the two conveying blocks 6 by the third motor 29. At this time, the inner hole of the guide cylinder 28, the arc-shaped through groove and the axis of the inner hole of the conveying block 6 coincide with each other, and the optical fiber is positioned inside the two conveying blocks 6 and inside the stripping block 4 in turn. Then, the conveying block 6 and the opening and closing block 13 are closed respectively, wherein the corresponding two conveying gears 23 will form a centering clamp for the optical fiber, and the opening and closing block 13 and the stripping block 4 are in a closed cutting state.

[0066] At this time, the output shaft of the first motor 10 is driven to rotate, driving the gear A8 to rotate, thereby driving the stripping block 4 and the opening and closing block 13 in the closed cutting state to rotate, thereby performing an annular cutting on the outer wall of the optical fiber;

[0067] At this time, by driving the stepper motor 24 to rotate, the conveying gear 23 is driven to rotate, and the optical fiber is conveyed to a fixed length, so that the cutting knife in the stripping block 4 spirally cuts the outer wall of the optical fiber; after reaching the set length, a circular cut is performed to complete the cutting and peeling. At this time, the conveying block 6 and the opening and closing block 13 are opened in turn, and the rocker 27 is swung backward to pull out the optical fiber.

[0068] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art will appreciate that modifications may be made to the technical solutions described in the above embodiments, or that some of the technical features may be replaced with equivalents; such modifications or replacements do not deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
