Fiber optic cutting clamping fixtures and laser cutting equipment

Abstract

This application discloses a fiber optic cleaving clamping fixture and a laser cleaving device. The fiber optic cleaving clamping fixture includes a fiber optic positioning base plate, a flip-locking cover, and a buffer clamping mechanism. The flip-locking cover is rotatably connected to the fiber optic positioning base plate. The buffer clamping mechanism is disposed on the flip-locking cover and corresponds to the slot structure. The buffer clamping mechanism includes a pressing block, a mounting block, and an elastic element. When a fiber optic product is placed on the fiber optic positioning base plate, the flip-locking cover separates from the fiber optic positioning base plate by a first angle, rotating the flip-locking cover relative to the fiber optic positioning base plate. The pressing block abuts and clamps against the fiber optic ferrule located in the slot structure. The mounting block buffers the rotational stress by squeezing or stretching the elastic element to keep the position of the pressing block relative to the fiber optic ferrule unchanged, preventing the fiber optic ferrule from being misaligned due to the rotational stress.

Description

Technical Field

[0001] This application relates to the field of fiber laser cutting technology, specifically to a fiber laser cutting clamping fixture and laser cutting equipment. Background Technology

[0002] In the fiber optic communication industry, the end face of optical fibers typically requires grinding and polishing, a relatively cumbersome and costly process. Laser cutting of optical fibers has emerged to meet optical requirements while improving efficiency and reducing costs. However, laser cutting is highly sensitive to focal length. Inconsistent fiber placement or pitch angles can lead to unstable end face angles and inconsistent lengths after cutting. Therefore, the fiber needs to be mounted on a fixture before cutting, and then the fixture is placed on the laser cutting machine. The operability and stability of the cutting fixture are therefore crucial. Current fiber clamping fixtures often fail to securely clamp and fix the fiber, easily causing misalignment and ultimately resulting in unstable laser cutting. Summary of the Invention

[0037] For details, please refer to Figures 1 to 4 This application provides an optical fiber cleaving clamping fixture 10 for clamping an optical fiber product 20. The optical fiber product 20 includes a main body shell 201 and an optical fiber ferrule 202. The optical fiber cleaving clamping fixture 10 includes an optical fiber limiting and placing base plate 1, a flip-locking cover 2, and a buffer clamping mechanism 3. The optical fiber limiting and placing base plate 1 has a contoured groove 11 in the middle for placing the main body shell 201, and a slot structure 12 at the first end for clamping the optical fiber ferrule 202. The flip-fitting cover 2 is aligned with the contoured groove 11; the flip-fitting cover 2 is rotatably connected to the first end of the fiber optic positioning base plate 1, and the flip-fitting cover 2 can be fastened and locked with the fiber optic positioning base plate 1; the buffer pressing mechanism 3 is provided on the flip-fitting cover 2 and is provided corresponding to the slot structure 12. The buffer pressing mechanism 3 includes a pressing block 31, a mounting block 32 and an elastic element 33. The pressing block 31 is provided on the mounting block 32, and the mounting block 32 is connected to the flip-fitting cover 2 through the elastic element 33.

[0038] When the optical fiber product 20 is placed on the optical fiber limiting placement base plate 1, the flip-locking cover 2 separates from the optical fiber limiting placement base plate 1 and opens to a first angle, which is 90° to 180°. The top surface of the main body shell 201 is flush with the upper surface of the optical fiber limiting placement base plate 1, and the top surface of the optical fiber ferrule 202 is flush with the upper surface of the slot structure 12. The flip-locking cover 2 is rotated relative to the optical fiber limiting placement base plate 1, and the pressure block 31 abuts and presses against the optical fiber ferrule 202 located in the slot structure 12. The mounting block 32 buffers the rotational stress by squeezing or stretching the elastic element 33 so that the position of the pressure block 31 relative to the optical fiber ferrule 202 remains unchanged, thus preventing the optical fiber ferrule 202 from being misaligned due to the rotational stress.

[0039] When the optical fiber product 20 is clamped between the optical fiber limiting placement base plate 1 and the flip-locking cover 2, the flip-locking cover 2 is locked to the optical fiber limiting placement base plate 1. This allows the flip-locking cover 2 to apply greater pressure to the optical fiber ferrule 202 to clamp the optical fiber ferrule 202, facilitating the laser cutting of the optical fiber cable 203 on the optical fiber ferrule 202.

[0040] The elastic element 33 is preferably a compression spring 123, a coil spring, or an elastic column. The pressure block 31 is made of an elastic buffer material, which can buffer stress deformation when the optical fiber ferrule 202 is compressed, thereby achieving tight clamping with the optical fiber ferrule 202. The optical fiber ferrule 202 is preferably a carrier for fiber insertion such as a jump, MT, or Mini MT.

[0041] Please see Figure 4 The flip-fitting cover 2 has a groove 21, and the buffer clamping mechanism 3 is located in the groove 21. This keeps the flip-fitting cover 2 flush with the side surface of the optical fiber limiting placement base plate 1, preventing interference with the optical fiber product 20.

[0042] Please see Figure 4 The flip-fitting cover 2 is rotatably connected to the first end of the fiber optic positioning base plate 1 via a rotating shaft 22. The pressure block 31, the mounting block 32, and the elastic element 33 are arranged sequentially, with the pressure block 31 located adjacent to the rotating shaft 22. At least two elastic elements 33 are provided in the groove 21, and the elastic elements 33 maintain the mounting block 32 in contact with the inner wall of the groove 21 through elastic force. When the flip-fitting cover 2 rotates relative to the fiber optic positioning base plate 1, the flip-fitting cover 2 will drive the pressure block 31 to rotate. The pressure block 31 is fixed on the mounting block 32. The mounting block 32 buffers the rotational stress by squeezing or stretching the elastic element 33 to keep the position of the pressure block 31 relative to the fiber optic ferrule 202 unchanged, preventing the fiber optic ferrule 202 from being misaligned due to rotational stress.

[0043] Understandably, the groove 21 is also provided with at least two guide posts, and the mounting block 32 is provided with through holes on both sides. The guide posts pass through the through holes, and the elastic element 33 is sleeved on the guide posts to realize that the mounting block 32 slides along the guide posts and avoids positional displacement.

[0044] Please see Figure 6A sliding limiting hole is provided at the bottom of the groove 21, and a limiting post 321 extends from the bottom of the mounting block 32. The limiting post 321 is slidably connected within the sliding limiting hole along the direction of the elastic member 33 to prevent positional displacement. When the elastic member 33 is stuck, the limiting post 321 can be manually moved to unlock it.

[0045] Please see Figure 3 The slot structure 12 includes an end limiting protrusion 121, a front spring placement block 122, a spring 123, and a rear spring placement block 124. A support plate 13 is provided at the first end of the fiber optic limiting placement base plate 1. The end limiting protrusion 121 is located on the first side of the support plate 13, the front spring placement block 122 is located on the second side of the support plate 13, and the rear spring placement block 124 is fixed on the fiber optic limiting placement base plate 1. The spring 123 is located between the front spring placement block 122 and the rear spring placement block 124. The end limiting protrusion 121 is higher than the top surface of the support plate 13, and the front spring placement block 122 is higher than the top surface of the support plate 13. The end limiting protrusion 121 and the front spring placement block 122 are used to clamp the fiber optic ferrule 202. That is, the area enclosed by the top surface of the support plate 13, the end limiting protrusion 121 and the front spring placement block 122 is used to clamp the optical fiber ferrule 202, and the end limiting protrusion 121 and the front spring placement block 122 clamp the two side edges of the optical fiber ferrule 202.

[0046] Please see Figure 2 The optical fiber product 20 includes an optical fiber cable 203, please refer to [link / reference]. Figure 3 The front spring placement block 122 and the rear spring placement block 124 are provided with cable slots 125 at positions corresponding to the contour groove 11. In this way, the optical fiber cable 203 is accommodated in the cable slots 125, so that the upper surfaces of the front spring placement block 122 and the rear spring placement block 124 are flush with the upper surface of the optical fiber limiting placement base plate 1.

[0047] Please see Figure 3 , Figure 6 , Figure 7 The slot structure 12 includes an end plate 126, and an end limiting protrusion 121 is provided on the end plate 126. The end plate 126 is detachably connected to the first side of the support plate 13. This detachable connection of the end plate 126 allows for replacement of only the end plate 126 if the end limiting protrusion 121 breaks or deforms due to prolonged stress, without requiring replacement of the entire fiber optic limiting base plate 1.

[0048] Please see Figure 7The end limiting protrusion 121 has a first placement slope 127 facing the front spring placement block 122, and the front spring placement block 122 has a second placement slope 128 facing the end limiting protrusion 121. The first placement slope 127 and the second placement slope 128 form a guide groove for installing the optical fiber ferrule 202. It is understood that the guide groove facilitates pressing the optical fiber ferrule 202 onto the slot structure 12. Preferably, the distance from the first placement slope 127 to the top surface of the support plate 13 is greater than or equal to the thickness of the optical fiber ferrule 202, and the distance from the second placement slope 128 to the top surface of the support plate 13 is greater than or equal to the thickness of the optical fiber ferrule 202.

[0049] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 The fiber optic limiting base plate 1 has lower hook blocks 14 on both sides, and the flip-fitting cover 2 has upper hook clamping blocks 23 extending from both sides. The upper hook clamping blocks 23 are hinged to the lower hook blocks 14 at the corresponding positions. The upper hook blocks 24 can be locked or unlocked by rotating the upper hook blocks 24. The upper hook blocks 24 abut against the end of the upper hook clamping blocks 23 through a return spring 25. The lower hook blocks 14 are C-shaped, and the upper hook blocks 24 are inverted C-shaped. The upper hook blocks 24 can be flipped and elastically reset. Thus, pressing the upper hook blocks 24 and rotating the upper hook blocks 24 can lock or unlock the lower hook blocks 14. The upper hook block 24 and the lower hook block 14 lock together to lock the flip-fitting cover 2 and the fiber optic positioning base plate 1 together. This presses the fiber optic ferrule 202 between the flip-fitting cover 2 and the fiber optic positioning base plate 1, increasing the pressing pressure between the pressure block 31 and the fiber optic ferrule 202 located in the slot structure 12. Furthermore, the pressing pressure on both sides of the fiber optic positioning base plate 1 is the same, allowing the flip-fitting cover 2 to apply greater pressure to the fiber optic ferrule 202 to clamp it. This facilitates laser cutting of the fiber optic ferrule 202 without misalignment during laser cutting.

[0050] Please see Figure 4 , Figure 6 The flip-fitting cover 2 is also provided with a flip handle protrusion 26 on the side opposite to the optical fiber limiting placement base plate 1. Preferably, the flip handle protrusion 26 is L-shaped, and the flip handle protrusion 26 is easy to flick or grasp with fingers, making it convenient to rotate and press or open the flip-fitting cover 2 relative to the optical fiber limiting placement base plate 1.

[0051] Please see Figure 2 The optical fiber product 20 includes a cable protection layer 204, please refer to [link / reference]. Figure 3 , Figure 6 An embedded protective plate 15 is provided at the second end of the optical fiber limiting placement base plate 1. The embedded protective plate 15 is provided with a wire groove 151 for placing the cable protection layer 204. The wire groove 151 and the contour groove 11 are arranged on a straight line.

[0052] The fiber optic cleaving clamping fixture 10 provided in this embodiment includes a fiber optic limiting and placing base plate 1, a flip-locking cover 2, and a buffer clamping mechanism 3. The fiber optic limiting and placing base plate 1 has a contoured groove 11 in the middle for placing the main body shell 201. The flip-locking cover 2 is rotatably connected to the fiber optic limiting and placing base plate 1. The buffer clamping mechanism 3 is disposed on the flip-locking cover 2 and corresponds to the slot structure 12. The buffer clamping mechanism 3 includes a pressing block 31, a mounting block 32, and an elastic element 33. When the flip-locking cover 2... When the fiber optic limiting base plate 1 rotates, the pressure block 31 abuts against and presses against the fiber optic ferrule 202 located in the slot structure 12. The mounting block 32 buffers the rotational stress by squeezing or stretching the elastic element 33 to keep the position of the pressure block 31 relative to the fiber optic ferrule 202 unchanged, thus preventing the fiber optic ferrule 202 from being misaligned due to the rotational stress. In this way, the flip-locking cover 2 can apply greater pressure to the fiber optic ferrule 202 to clamp it, which facilitates laser cutting of the fiber on the fiber optic ferrule 202.

[0054] Please see Figure 8 , Figure 9The laser cutting equipment 100 further includes a fixture fixing base 30 and a laser cutting head 40; the fixture fixing base 30 is provided with a first front and rear sliding seat 31 and a second front and rear sliding seat 32, the fiber optic cutting clamping fixture 10 is fixed on the upper surface of the fixture fixing base 30, the laser cutting head 40 is disposed above the fiber optic cutting clamping fixture, and a gap is provided between the laser cutting head 40 and the fiber optic cutting clamping fixture 10; the laser cutting head 40 includes a laser generating module 41, a beam reflecting mechanism 42, a transverse laser head 43, a transverse driving mechanism 44, and a focusing mechanism 45, the laser beam generated by the laser generating module 41 is transmitted into the transverse laser head 43 through the beam reflecting mechanism 42, the transverse driving mechanism 44 drives the transverse laser head 43 to move along the width direction of the fiber optic limiting placement base plate 1, and the focusing mechanism 45 focuses the laser beam emitted by the transverse laser head 43 to cut the fiber optic cable 203 fixed on the fiber optic cutting clamping fixture 10 at the fiber optic ferrule 202.
