DETAILED DESCRIPTION

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0034] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0035] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] See also Figures 1 to 6 The optical fiber end face cutting device provided in the embodiment of the present application is now described. The optical fiber end face cutting device is used for end face cutting of an optical fiber bundle, specifically, end face cutting of a melt-drawn optical fiber bundle, end face cutting of a melt-cone optical fiber bundle, or end face cutting of an ordinary optical fiber bundle.

[0038] The optical fiber end face cutting device includes a frame 100, a cutter 300 installed on the frame 100, and a positioning seat 200 installed on the frame 100. The positioning seat 200 and the cutter 300 are distributed along the first direction X; the positioning seat 200 has a positioning groove 230 that penetrates along the first direction X and is used to limit the optical fiber bundle. The positioning seat 200 also has an adsorption hole 221 connected to the positioning groove 230, and the adsorption hole 221 is configured to be connected to an external vacuum device.

[0039] Before cutting, the optical fiber bundle is first passed through the positioning groove 230 of the positioning seat 200 along the first direction X, and the portion of the optical fiber bundle to be cut corresponds to the cutter 300; then, the adsorption hole 221 is evacuated by a vacuum device to adsorb and position the optical fiber bundle in the positioning groove 230; after the optical fiber bundle is positioned, the negative pressure can be increased to fix the optical fiber bundle in the positioning groove 230, or the optical fiber bundle can be fixed by adhesive; finally, the optical fiber bundle is cut by the cutter 300.

[0040] The optical fiber end face cutting device in the embodiment of the present application, by providing a positioning groove 230 penetrating along the first direction X in the positioning seat 200, and providing an adsorption hole 221 in the positioning seat 200 that is connected to the positioning groove 230 and connected to the vacuum equipment, so that the position of the optical fiber bundle corresponding to the positioning groove 230 can be adsorbed and fixed in the positioning groove 230 by vacuum adsorption, which not only ensures firm positioning, but also does not require additional clamps, thereby avoiding damage to the optical fiber bundle due to the setting of the clamp and preventing contamination of the optical fiber bundle.

[0041] In some embodiments, see Figure 4 and Figure 5The positioning seat 200 has a plurality of adsorption holes 221, each of which is evenly spaced along the first direction X, and each of which is connected to the positioning groove 230. By equidistantly distributing the adsorption holes 221 along the first direction X, the negative pressure in each of the adsorption holes 221 can be used to adsorb different positions of the optical fiber bundle along the first direction X, thereby ensuring that the adsorption force distribution of each part of the optical fiber bundle is uniform. In addition, by providing a plurality of adsorption holes 221, the effect of throttling and controlling pressure can be achieved, thereby ensuring that the adsorption force is stable.

[0042] In some embodiments, see Figures 4 to 6 The central axis of each adsorption hole 221 is located at the central plane of the positioning groove 230 along the second direction Y. The second direction Y is perpendicular to the first direction X, and the second direction Y is perpendicular to the central axis of the adsorption hole 221.

[0043] Specifically, the structures and sizes of the adsorption holes 221 are the same, and the adsorption holes 221 are distributed at equal intervals in sequence along the first direction X. The central axes of the adsorption holes 221 are located in the same plane, which is called the first plane. When the central axes of the adsorption holes 221 are located at the central plane of the positioning groove 230 along the second direction Y, that is, the central axes of the adsorption holes 221 are all located at the central plane of the positioning groove 230 along the second direction Y.

[0044] When assembling the optical fiber bundle, the user manually installs the corresponding position of the optical fiber bundle into the positioning groove 230. At this time, the vacuum equipment can be controlled so that each adsorption hole 221 has a slight adsorption force to adsorb the optical fiber bundle to the first plane of each adsorption hole 221, that is, the optical fiber bundle is adsorbed and positioned to the center plane of the positioning groove 230, thereby realizing the precise positioning of the optical fiber bundle; after the optical fiber bundle is positioned, the vacuum equipment is controlled again so that each adsorption hole 221 has a greater adsorption force to produce a clamping effect on the optical fiber bundle, thereby ensuring the installation reliability of the optical fiber bundle.

[0045] In this embodiment, the above structural design can reduce the difficulty of positioning the optical fiber bundle by the user. It can be understood that in other embodiments of the present application, the user can also manually position the optical fiber bundle completely in the positioning groove 230 without specially setting the position of the adsorption hole 221.

[0046] In some embodiments, see Figure 4The positioning groove 230 passes through the side of the positioning seat 200 away from the adsorption hole 221. When the positioning seat 200 is placed vertically, the central axis of the adsorption hole 221 extends in the vertical direction, and the positioning groove 230 passes through the top side of the positioning seat 200. The above arrangement allows the optical fiber bundle to be installed into the positioning groove 230 from the top opening of the positioning groove 230 in the vertical direction when assembling the optical fiber bundle, and the optical fiber bundle is positioned at the center of the positioning groove 230 through the adsorption effect of the adsorption hole 221, without inserting the optical fiber bundle into the positioning groove 230 along the axial direction of the positioning groove 230, thereby reducing the difficulty of assembly and positioning of the optical fiber bundle.

[0047] In some embodiments, see Figure 6 The positioning groove 230 includes an introduction portion 231 and a positioning portion 232 that are interconnected. The longitudinal cross-section of the positioning portion 232 is semicircular. The inner diameter of the positioning portion 232 is set to match the outer diameter of the optical fiber bundle. Each adsorption hole 221 is connected to the positioning portion 232. The longitudinal cross-section of the introduction portion 231 is rectangular. The width of the introduction portion 231 along the second direction Y is the same as the inner diameter of the positioning portion 232. The optical fiber bundle is loaded from the introduction portion 231 away from the top opening of the positioning portion 232, and is adsorbed and fixed in the positioning portion 232 under the adsorption action of the adsorption hole 221. It can be understood that in other embodiments of the present application, the introduction portion 231 can also be designed to be a shape in which the width along the second direction Y gradually increases from the top opening to the positioning portion 232, and this is not the only limitation here.

[0048] In some embodiments, see Figure 4 The positioning seat 200 has a connecting hole 211 and a connecting groove 212 connected along the central axis direction of the adsorption hole 221. The connecting hole 211 is used to install a joint, and the joint is connected to the vacuum device. The connecting groove 212 is located between the adsorption hole 221 and the connecting hole 211. The connecting groove 212 is connected to each adsorption hole 221 respectively. The opposite ends of the connecting groove 212 along the first direction X extend to the outside of the opposite ends of each adsorption hole 221 along the first direction X. The setting of the connecting groove 212 can evenly transfer the negative pressure of the vacuum device to each adsorption hole 221, so that the negative pressure at each adsorption hole 221 is evenly distributed.

[0049] In some embodiments, see Figure 4The positioning seat 200 includes a seat body 210 and an adsorption block 220. The seat body 210 has a connecting hole 211, a connecting groove 212 and a mounting groove 213 that are sequentially connected along the central axis direction of the adsorption hole 221. The adsorption block 220 is installed in the mounting groove 213. Each adsorption hole 221 is formed in the adsorption block 220, and the positioning groove 230 passes through the seat body 210 and the adsorption block 220. In this embodiment, the adsorption block 220 having multiple adsorption holes 221 is separately provided with the seat body 210, so as to reduce the processing accuracy requirements of the seat body 210, reduce the manufacturing cost of the seat body 210, and also facilitate the molding of the connecting groove 212. It can be understood that in other embodiments of the present application, the seat body 210 and the adsorption block 220 can also be connected as one body, which is not the only limitation here.

[0050] Optionally, the adsorption block 220 can be fixed to the base body 210 by screw locking, clamping or bonding.

[0051] In some embodiments, see Figures 1 to 3 The optical fiber end face cutting device includes two positioning seats 200 respectively arranged on opposite sides of the cutter 300 along the first direction X; the optical fiber end face cutting device also includes a first driving mechanism 400 and a second driving mechanism 500, the first driving mechanism 400 is used to drive the two positioning seats 200 to rotate to drive the optical fiber bundle to rotate relative to the cutter 300, so that the cutter 300 cuts the optical fiber bundle; the second driving mechanism 500 is used to drive the two positioning seats 200 to move in opposite directions along the first direction X to pull the optical fiber bundle.

[0052] During the specific operation, different parts of the optical fiber bundle are first positioned in the two positioning seats 200 respectively, and the part of the optical fiber bundle to be cut just abuts the cutter 300; then, the two positioning seats 200 are driven to rotate around the center line of the cutter 300 by the first driving mechanism 400, so that the optical fiber bundle slides along the cutting edge 310 of the cutter 300, so that the cutter 300 can cut a break in the optical fiber bundle; then, the two positioning seats 200 are driven by the second driving mechanism 500 to move in opposite directions along the first direction X, so that a single optical fiber of the fused optical fiber bundle is pulled off to obtain a flat end face.

[0053] In the embodiment of the present application, the fiber bundle is driven to rotate to cut the fiber bundle, and the end face of the fiber bundle is formed by breaking the fiber bundle, which can effectively improve the efficiency of smooth cutting of the fused cone fiber bundle in the production process of the end pump combiner. It can be understood that in other embodiments of the present application, the number of the positioning seat 200 can also be one, three, or more than three. In addition, in other embodiments, the fiber bundle can also be cut by driving the cutter 300 to rotate.

[0054] In some embodiments, see Figure 2 and Figure 3, a connecting assembly 600 is connected between the two positioning seats 200, and the connecting assembly 600 is used to form a synchronous rotation connection between the two positioning seats 200, and the connecting assembly 600 is also used to form a sliding connection between the two positioning seats 200 along the first direction X. In this embodiment, through the setting of the connecting assembly 600, the synchronous rotation connection of the two positioning seats 200 can be achieved, that is, the first driving mechanism 400 only needs to drive one positioning seat 200 to rotate, and can drive the two positioning seats 200 to rotate synchronously, so that the parts of the optical fiber bundle located on the opposite sides of the cutter 300 can be driven to rotate synchronously, so that the part of the optical fiber bundle corresponding to the cutter 300 slides circumferentially on the cutter 300. In addition, the connecting assembly 600 can also enable the two positioning seats 200 to slide relatively along the first direction X, so that after cutting, the optical fiber bundle can be pulled apart by driving the two positioning seats 200 to form an end face. It can be understood that in other embodiments of the present application, the connecting component 600 may not be provided, and the first driving mechanism 400 includes two groups of driving components, and the two groups of driving components respectively drive the two positioning seats 200 to rotate. At this time, the two groups of driving components can be controlled by the circuit to work synchronously. In addition, one motor can be used through multiple transmission structures to achieve the synchronous rotation of the two positioning seats 200. This is not a sole limitation here.

[0055] In some embodiments, see Figure 3 , Figures 7 to 10 The connection assembly 600 includes a first connection member 610 and a second connection member 620. The first connection member 610 and the second connection member 620 are connected to two positioning seats 200 respectively. The first connection member 610 has a receiving groove 611 with an opening toward the second connection member 620. The inner peripheral wall of the receiving groove 611 is provided with a first plug-in portion 612 extending along its axial direction. The outer peripheral wall of the second connection member 620 is provided with a second plug-in portion 621 extending along its axial direction. The second connection member 620 can be plugged into the receiving groove 611. The first plug-in portion 612 and the second plug-in portion 621 are correspondingly plugged and matched. When the first connection member 610 and the second connection member 620 are plugged and matched, the first plug-in portion 612 and the second plug-in portion 621 can be abutted and limited along the circumferential direction so that the first connection member 610 and the second connection member 620 can rotate synchronously, thereby enabling the two positioning seats 200 to rotate synchronously. In addition, since the first plug-in portion 612 and the second plug-in portion 621 are axially slidably connected, the first connecting member 610 and the second connecting member 620 are axially slidably connected, and further the two positioning seats 200 are axially slidably connected.

[0056] Optionally, the inner peripheral wall of the receiving groove 611 is distributed with a plurality of first plug-in portions 612 distributed in sequence and at equal intervals along the circumferential direction, and the outer peripheral wall of the second connecting member 620 is distributed with a plurality of second plug-in portions 621 distributed in sequence and at equal intervals along the circumferential direction, and each first plug-in portion 612 is plugged and matched with each second plug-in portion 621 in a one-to-one correspondence. It can be understood that in other embodiments, the number of the first plug-in portion 612 and the second plug-in portion 621 can also be one, which is not limited here.

[0057] In some embodiments, the first plug-in portion 612 is a groove, and the second plug-in portion 621 is a convex strip. Optionally, the opening of the first plug-in portion 612 gradually increases from the bottom to the top, so that the second plug-in portion 621 can be inserted into the first plug-in portion 612. In other embodiments of the present application, the first plug-in portion 612 can also be a convex strip, and the second plug-in portion 621 can be a groove.

[0058] In some embodiments, see Figure 3 and Figure 7 The optical fiber end face cutting device further includes two third connecting members 630, one of which is connected between one of the positioning seats 200 and the first connecting member 610, and the other is connected between the other positioning seat 200 and the second connecting member 620. The two third connecting members 630 extend in the vertical direction, and the two third connecting members 630 are respectively arranged on opposite sides of the cutter 300 along the first direction X, and the first connecting member 610 and the second connecting member 620 are arranged below the cutter 300. In this embodiment, by setting the two third connecting members 630, the two positioning seats 200 can be connected through the first connecting member 610 and the second connecting member 620 located below the cutter 300. It can be understood that in other embodiments of the present application, the first connecting member 610 and the second connecting member 620 can also be arranged above the cutter 300 or on opposite sides of the cutter 300 along the second direction Y.

[0059] In some embodiments, see Figure 1 , Figure 2 and Figure 7, the first driving mechanism 400 is arranged on the side of one of the positioning seats 200 away from the cutter 300 and connected to the positioning seat 200 to drive the two positioning seats 200 to rotate. Specifically, the first driving mechanism 400 includes a first driving member 410, a driving wheel 420 and a driven wheel 430. The first driving member 410 is installed on the frame 100. The first driving member 410 is used to output rotational motion. The driving wheel 420 is connected to the output end of the first driving member 410. The driven wheel 430 is meshed with the driving wheel 420 for transmission. One of the positioning seats 200 is coaxially connected to the driven wheel 430. The first driving member 410 can drive the positioning seat 200 to rotate via the driving wheel 420 and the driven wheel 430. It can be understood that in other embodiments of the present application, one of the first connecting member 610 and the second connecting member 620 can also be connected to the first driving mechanism 400, which is not limited here.

[0060] Optionally, the first driving member 410 is a rotary motor or a rotary cylinder.

[0061] In some embodiments, see Figure 4 The positions of the frame 100 corresponding to the two positioning seats 200 are each provided with a mounting seat 900 , and the mounting seat 900 has a circular assembly groove, the positioning seat 200 is rotatably mounted in the assembly groove, and the positioning seat 200 can slide along the first direction X relative to the assembly groove.

[0062] In some embodiments, see Figure 3 and Figure 7 The second driving mechanism 500 is connected to the first connecting member 610 or the third connecting member 630, and the second driving mechanism 500 is used to drive the first connecting member 610 or the third connecting member 630 to slide in a direction away from the second connecting member 620, so that the two positioning seats 200 slide in opposite directions. It can be understood that in other embodiments of the present application, the first driving mechanism 400 and the second driving mechanism 500 can also be connected to the two positioning seats 200 respectively.

[0063] In some embodiments, see Figure 3 and Figure 7, the second driving mechanism 500 is arranged below the connecting assembly 600, and the second driving mechanism 500 includes a second driving member 510, a first screw rod 520 and a first nut 530. The second driving member 510 is installed on the frame 100, and the second driving member 510 is used to output rotational motion. The first screw rod 520 is rotatably arranged on the frame 100, and the first nut 530 is slidably sleeved on the first screw rod 520, and the first nut 530 is connected to the first connecting member 610 or the third connecting member 630. When the second driving member 510 drives the first screw rod 520 to rotate, the first connecting member 610 can be driven to slide along the first direction X through the first nut 530. Specifically, the second driving member 510 is a rotating motor or a rotating cylinder, and a first coupling is connected between the second driving member 510 and the first screw rod 520. It can be understood that in other embodiments of the present application, the second driving mechanism 500 can also be a ball screw mechanism, a gear rack mechanism or a synchronous belt mechanism.

[0064] In some embodiments, see Figure 8 and Fig. 9 A fourth connecting member 640 is connected between the second driving mechanism 500 and the first connecting member 610. The fourth connecting member 640 is installed at the output end of the second driving mechanism 500. An arc groove 641 is formed on the fourth connecting member 640. A connecting shaft 613 is formed on the first connecting member 610. The connecting shaft 613 is slidably arranged in the arc groove 641. The fourth connecting member 640 abuts against the left side of the third connecting member 630 on the right side, so that when the first connecting member 610 rotates, the fourth connecting member 640 will not rotate. When the fourth connecting member 640 slides, it can push the third connecting member 630 on the right side to slide, thereby pushing the positioning seat 200 to slide. It should be noted here that for the convenience of description, the two third connecting members 630 are referred to as the left or right third connecting members 630. In fact, according to the different assembly directions of the entire device, the relative orientations of the two third connecting members 630 are also different.

[0065] In some embodiments, see Fig.11 , the cutter 300 is circular, and the thickness of the cutter 300 along the first direction X gradually decreases from the center to the periphery to form a circular cutting blade 310 at the periphery. In this embodiment, by setting the cutter 300 to be circular and forming the cutting blade 310 at the periphery of the cutter 300, when the optical fiber bundle rotates around the center of the cutter 300, the optical fiber bundle can slide on the circular cutting blade 310, so that the cutting blade 310 can cut a circle of openings in the optical fiber bundle along the circumferential direction, so that when the two positioning seats 200 pull the optical fiber bundle in opposite directions, the optical fiber bundle can be broken. In other embodiments of the present application, the cutter 300 can also be semicircular or three-quarter circular, etc., which is not limited here.

[0066] In some embodiments, see Fig.11The optical fiber end face cutting device further comprises a knife holder 700, on which the cutter 300 is mounted, the knife holder 700 having a through slot penetrating along the first direction X, the cutter 300 being mounted in the through slot, and an annular groove 710 is formed between the outer circumferential wall of the cutter 300 and the inner circumferential wall of the through slot. The setting of the annular groove 710 can limit the optical fiber bundle in the annular groove 710, prevent the optical fiber bundle from being separated from the cutting blade 310, ensure that the optical fiber bundle can be pressed against the cutting blade 310, and ensure the cutting effect of the cutting blade 310 on the optical fiber bundle.

[0067] For details, please refer to Fig.11 The top of the tool holder 700 has a notch 720 connected to the annular groove 710 , and the optical fiber bundle can be loaded into the annular groove 710 through the notch 720 .

[0068] See also Fig.11 The knife holder 700 includes a connecting portion 730 and a mounting portion 740. The mounting portion 740 is in a circular ring shape. The cutter 300 is installed in the through groove of the mounting portion 740. The connecting portion 730 is connected to the mounting portion 740. One end of the connecting portion 730 extends to the center position of the mounting portion 740 to install the cutter 300. The cutter 300 can be locked to one end of the connecting portion 730 by fasteners such as screws, and the other end of the connecting portion 730 extends out of the mounting portion 740 to be connected to the frame 100.

[0069] In some embodiments, see Figure 4 The optical fiber end face cutting device further includes an adjustment structure 800, which is mounted on the frame 100 and is used to adjust the position of the cutter 300 along the first direction X, the second direction Y and the vertical direction. Specifically, during structural assembly, the position of the cutter 300 can be adjusted by the adjustment structure 800, so that when the optical fiber bundle is positioned at the two positioning seats 200, the optical fiber bundle just abuts against the cutting edge 310 of the cutter 300, thereby ensuring the cutting effect of the cutter 300 on the optical fiber bundle.

[0070] In some embodiments, see Fig.12 The adjustment structure 800 includes a first adjustment component 810, a second adjustment component 820 and a third adjustment component 830; the first adjustment component 810 is installed on the frame 100, and is used to output linear motion along the first direction X; the second adjustment component 820 is installed at the output end of the first adjustment component 810, and is used to output linear motion along the vertical direction; the third adjustment component 830 is installed at the output end of the second adjustment component 820 and is used to output linear motion along the second direction Y, and the cutter 300 is installed at the output end of the third adjustment component 830.

[0071] When the position of the cutter 300 needs to be adjusted along the second direction Y, it needs to be adjusted through the third adjustment component 830; when the position of the cutter 300 needs to be adjusted along the vertical direction, the third adjustment component 830 and the cutter 300 need to be driven by the second adjustment component 820 to move together along the vertical direction; when the position of the cutter 300 needs to be adjusted along the first direction X, the second adjustment component 820, the third adjustment component 830 and the cutter 300 need to be driven by the first adjustment component 810 to move together along the first direction X. The arrangement of the first adjustment component 810, the second adjustment component 820 and the third adjustment component 830 connected in sequence not only enables the position of the cutter 300 to be automatically adjusted, but also makes the adjustment structure 800 occupy a small space. It can be understood that in other embodiments of the present application, the position of the cutter 300 can also be adjusted individually through three groups of adjustment components, for example, by setting strip grooves extending along the first direction X, the second direction Y and the vertical direction, and locking different positions of the strip grooves through fasteners, thereby adjusting the position of the cutter 300 along the first direction X, the second direction Y and the vertical direction.

[0072] In some embodiments, see Fig.12 , the first adjustment component 810, the second adjustment component 820 and the third adjustment component 830 are all screw-nut structures, for example, the first adjustment component 810 includes a third driving member 811, a second screw 812 and a second nut 813, the second screw 812 is connected to the output shaft of the third driving member 811 through a second coupling, the second nut 813 is threadedly sleeved on the second screw 812, the second adjustment component 820 is installed on the second nut 813, and so on. It can be understood that in other embodiments of the present application, the first adjustment component 810, the second adjustment component 820 and the third adjustment component 830 can also be a ball screw mechanism, a gear rack mechanism, etc.

[0073] Optionally, the third driving member 811 is a motor.

[0074] Optionally, the optical fiber end face cutting device also includes a control board, and the first driving member 410, the second driving member 510 and the third driving member 811 are all electrically connected to the control board, which controls the start and stop and working sequence of the first driving member 410, the second driving member 510 and the third driving member 811.

[0075] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
