DETAILED DESCRIPTION

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

[0034] It should be noted that when an element is referred to as being "fixed to" or "set 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", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only used to facilitate the description of the present application and simplify the description, and therefore cannot be understood as indicating or implying that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0036] In addition, the terms "first", "second", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined as "first", "second", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly and specifically limited.

[0037] Referring to Figures 1 to 6 The optical fiber end face cutting device provided by the embodiment of the present application will be described. The optical fiber end face cutting device is used for end face cutting of an optical fiber bundle, and can be specifically used for end face cutting of a fusion-spun optical fiber bundle, end face cutting of a fusion taper optical fiber bundle, or end face cutting of a common optical fiber bundle.

[0038] The optical fiber end face cutting device comprises a rack 100, a cutting knife 300 mounted on the rack 100, and a positioning seat 200 mounted on the rack 100, the positioning seat 200 and the cutting knife 300 being distributed along a first direction X; the positioning seat 200 has a positioning groove 230 penetrating along the first direction X and used for limiting an optical fiber bundle, and the positioning seat 200 further has a suction hole 221 communicating with the positioning groove 230, the suction hole 221 being configured to communicate with an external vacuum equipment.

[0039] Before cutting, the optical fiber bundle is first penetrated through the positioning groove 230 of the positioning seat 200 along the first direction X, and the part of the optical fiber bundle to be cut corresponds to the cutting knife 300; then, the vacuum equipment is used to perform vacuum suction on the suction hole 221 to position the optical fiber bundle in the positioning groove 230; after the optical fiber bundle is positioned, the optical fiber bundle can be fixed in the positioning groove 230 by increasing the negative pressure, or the optical fiber bundle can be fixed by pasting glue; finally, the cutting knife 300 is used to cut the optical fiber bundle.

[0040] The optical fiber end face cutting device in the embodiment of the present application has the positioning groove 230 penetrating along the first direction X in the positioning seat 200, and the suction hole 221 communicating with the positioning groove 230 and communicating with the vacuum equipment in the positioning seat 200, so that the optical fiber bundle can be fixed in the positioning groove 230 by vacuum suction at the position corresponding to the positioning groove 230. The positioning is firm, and no additional clamp is needed, so that damage to the optical fiber bundle caused by the clamp can be avoided, and the optical fiber bundle is not polluted.

[0041] In some embodiments, referring to Figure 4 and Figure 5The positioning seat 200 has a plurality of adsorption holes 221, each of which is distributed along the first direction X at equal intervals, and each of which is in communication with the positioning groove 230. By distributing the adsorption holes 221 along the first direction X at equal intervals, the negative pressure in each adsorption hole 221 can be used to adsorb the optical fiber bundle at different positions along the first direction X, thereby ensuring that the adsorption force is uniformly distributed at different positions of the optical fiber bundle. In addition, the plurality of adsorption holes 221 can achieve the effect of throttling the pressure, thereby ensuring the stability of the adsorption force.

[0042] In some embodiments, referring to Figures 4 to 6 The center axis of each adsorption hole 221 is located on the center surface of the positioning groove 230 along the second direction Y, which is perpendicular to the first direction X and perpendicular to the center axis of the adsorption hole 221.

[0043] Specifically, each adsorption hole 221 has the same structure and size, and is distributed along the first direction X at equal intervals. The center axis of each adsorption hole 221 is located on the same plane, which is referred to as the first plane. When the center axis of each adsorption hole 221 is located on the center surface of the positioning groove 230 along the second direction Y, the center axis of each adsorption hole 221 is located on the center surface of the positioning groove 230 along the second direction Y.

[0044] When assembling the optical fiber bundle, the user manually inserts the corresponding position of the optical fiber bundle into the positioning groove 230. At this time, the vacuum equipment can be controlled to make each adsorption hole 221 have a slight adsorption force to adsorb the optical fiber bundle to the first plane of each adsorption hole 221, that is, to adsorb and position the optical fiber bundle to the center surface of the positioning groove 230, thereby achieving precise positioning of the optical fiber bundle. After the optical fiber bundle is positioned, the vacuum equipment is controlled again to make each adsorption hole 221 have a greater adsorption force to produce a clamping effect on the optical fiber bundle, thereby ensuring the installation stability of the optical fiber bundle.

[0045] In the present embodiment, the above structure design can reduce the difficulty of the user positioning the optical fiber bundle. 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 special positioning of the adsorption holes 221.

[0046] In some embodiments, referring to Figure 4The positioning groove 230 penetrates through the positioning base 200 from the side away from the adsorption hole 221. When the positioning base 200 is vertically placed, the central axis of the adsorption hole 221 extends in the vertical direction, and the positioning groove 230 penetrates through the top side of the positioning base 200. The above arrangement makes it only necessary to insert the optical fiber bundle into the positioning groove 230 from the top opening of the positioning groove 230 in the vertical direction and position the optical fiber bundle in the center of the positioning groove 230 through the adsorption of the adsorption hole 221 when assembling the optical fiber bundle, without the need to insert the optical fiber bundle into the positioning groove 230 in the axial direction of the positioning groove 230, thereby reducing the difficulty of assembling and positioning the optical fiber bundle.

[0047] In some embodiments, referring to Figure 6 The positioning groove 230 includes an introduction part 231 and a positioning part 232 that are in communication with each other. The longitudinal section of the positioning part 232 is semicircular, and the inner diameter of the positioning part 232 is designed to be matched with the outer diameter of the optical fiber bundle. Each adsorption hole 221 is in communication with the positioning part 232. The longitudinal section of the introduction part 231 is rectangular, and the width of the introduction part 231 in the second direction Y is the same as the inner diameter of the positioning part 232. The optical fiber bundle is inserted from the top opening of the introduction part 231 away from the positioning part 232 and is adsorbed and fixed in the positioning part 232 under the adsorption of the adsorption hole 221. It can be understood that in other embodiments of the present application, the introduction part 231 can also be designed to gradually increase in width from the top opening to the positioning part 232 in the second direction Y, which is not limited here.

[0048] In some embodiments, referring to Figure 4 The positioning base 200 has a connecting hole 211 and a connecting groove 212 that are in communication along the central axis direction of the adsorption hole 221. The connecting hole 211 is used to install a connector that is connected to a vacuum device. The connecting groove 212 is located between the adsorption hole 221 and the connecting hole 211 and is in communication with each adsorption hole 221, respectively. The connecting groove 212 extends to the outside of the opposite ends of each adsorption hole 221 in the first direction X, respectively. The connecting groove 212 can uniformly transmit the negative pressure of the vacuum device to each adsorption hole 221, so that the negative pressure distribution at each adsorption hole 221 is uniform.

[0049] In some embodiments, referring to 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 which are sequentially communicated along the central axis direction of the adsorption hole 221. The adsorption block 220 is mounted in the mounting groove 213. Each adsorption hole 221 is formed in the adsorption block 220. The positioning groove 230 penetrates the seat body 210 and the adsorption block 220. In the embodiment, the adsorption block 220 with multiple adsorption holes 221 is separately arranged with the seat body 210, so that the machining precision requirement of the seat body 210 is reduced, the manufacturing cost of the seat body 210 is reduced, and the forming of the connecting groove 212 is facilitated. It can be understood that in other embodiments of the application, the seat body 210 and the adsorption block 220 can be integrally connected, which is not limited herein.

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

[0051] In some embodiments, referring to Figures 1 to 3 The fiber end face cutting device includes two positioning seats 200 which are respectively arranged on the opposite sides of the cutter 300 along the first direction X. The fiber end face cutting device further 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 away from each other along the first direction X to break the optical fiber bundle.

[0052] In specific operation, different parts of the optical fiber bundle are positioned in the two positioning seats 200, and the part to be cut of the optical fiber bundle abuts against the cutter 300. Then, the first driving mechanism 400 drives the two positioning seats 200 to rotate around the center line of the cutter 300, so that the optical fiber bundle slides along the cutting edge 310 of the cutter 300, and the cutter 300 can cut the optical fiber bundle to form a break. Then, the second driving mechanism 500 drives the two positioning seats 200 to move away from each other along the first direction X, so that the single optical fiber of the fusion-spun optical fiber bundle is broken to obtain a flat end face.

[0053] In the embodiment, the end face of the optical fiber bundle is formed by driving the rotation of the optical fiber bundle to cut the optical fiber bundle and break the optical fiber bundle, which can effectively improve the efficiency of the flat cutting of the fusion-spun optical fiber bundle in the production process of the end-pumped beam combiner. It can be understood that in other embodiments of the application, the number of the positioning seats 200 can be one, three or more than three. In addition, in other embodiments, the optical fiber bundle can be cut by driving the rotation direction of the cutter 300.

[0054] In some embodiments, referring to Figure 2 and Figure 3The two positioning seats 200 are connected with a connecting assembly 600, the connecting assembly 600 is used for forming synchronous rotation connection of the two positioning seats 200, and the connecting assembly 600 is also used for forming sliding connection of the two positioning seats 200 along the first direction X. In the embodiment, through the arrangement of the connecting assembly 600, synchronous rotation connection of the two positioning seats 200 can be realized, that is, the first driving mechanism 400 only needs to drive one positioning seat 200 to rotate, and the two positioning seats 200 can be driven to rotate synchronously, so that the part 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 can slide on the cutter 300 in the circumferential direction. In addition, the connecting assembly 600 can also enable the two positioning seats 200 to slide relative to each other along the first direction X, so that the optical fiber bundle can be pulled off to form an end face by driving the two positioning seats 200 after cutting. It can be understood that in other embodiments of the application, the connecting assembly 600 can also not be arranged, the first driving mechanism 400 includes two groups of driving assemblies, and the two groups of driving assemblies drive the two positioning seats 200 to rotate respectively, at this time, the two groups of driving assemblies can be controlled to work synchronously through a circuit, and in addition, a motor can also be used to realize synchronous rotation of the two positioning seats 200 through a plurality of transmission structures, which is not limited here.

When the first connecting piece 610 and the second connecting piece 620 are plugged and matched, the first plug-in part 612 and the second plug-in part 621 can be limited in position in the circumferential direction, so that the first connecting piece 610 and the second connecting piece 620 can rotate synchronously, thereby enabling the two positioning seats 200 to rotate synchronously. In addition, since the first plug-in part 612 and the second plug-in part 621 are connected in the axial direction, the first connecting piece 610 and the second connecting piece 620 are connected in the axial direction, and the two positioning seats 200 are connected in the axial direction.

[0056] Optionally, the inner circumferential wall of the accommodating groove 611 is provided with a plurality of first plug-in parts 612 which are equally spaced along the circumferential direction, and the outer circumferential wall of the second connecting member 620 is provided with a plurality of second plug-in parts 621 which are equally spaced along the circumferential direction, each first plug-in part 612 is in plug-in cooperation with each second plug-in part 621. It can be understood that in other embodiments, the number of the first plug-in parts 612 and the second plug-in parts 621 can also be one, which is not limited herein.

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

[0058] In some embodiments, referring to Figure 3 and Figure 7 , the fiber end face cutting device further comprises 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 of which is connected between the other positioning seat 200 and the second connecting member 620. The two third connecting members 630 extend along the vertical direction, and the two third connecting members 630 are respectively arranged on the 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, the two positioning seats 200 are connected through the first connecting member 610 and the second connecting member 620 which are arranged below the cutter 300 by the arrangement of the two third connecting members 630. 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 the opposite sides of the cutter 300 along the second direction Y.

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 with the first driving mechanism 400, which is not limited herein.

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

[0061] In some embodiments, referring to Figure 4 The frame 100 is provided with a mounting seat 900 corresponding to the positions of the two positioning seats 200.

[0062] In some embodiments, referring to Figure 3 and Figure 7 The second driving mechanism 500 is connected with the first connecting member 610 or the third connecting member 630. 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 as to make the two positioning seats 200 slide away from each other. It can be understood that in other embodiments of the present application, the first driving mechanism 400 and the second driving mechanism 500 can be respectively connected with the two positioning seats 200.
