[0036] like Figure 1 and Figure 2As shown, the utility model provides an optical fiber dispensing and curing device 1, comprising: a base 11 and a first cover plate 12; a receiving groove 111 is provided on the base 11, and the receiving groove 111 is used to accommodate the non-dispensing part of the optical fiber 2; a first mounting groove 112 is respectively provided at both ends of the receiving groove 111, and the first mounting groove 112 is used to accommodate a film 3; when the film 3 is accommodated in the first mounting groove 112, the central axis of the film 3 is aligned with the central axis of the receiving groove 111; the first cover plate 12 is movably arranged on the base 11, and the first cover plate 12 can move between a first position and a second position; in the first position, the first cover plate 12 is used to press the optical fiber 2 against the two ends of the receiving groove 111; in the second position, the first cover plate 12 is away from the receiving groove 111 to loosen the optical fiber 2.

[0037] In this embodiment, the base 11 is used to hold the optical fiber 2 and the film 3 when preparing samples. Specifically, the base 11 is provided with a receiving groove 111 adapted to the optical fiber 2, and the non-glue-dispensing part of the optical fiber 2 can be placed in the receiving groove 111, and is limited by the receiving groove 111 to remain straight; by providing first installation grooves 112 at both ends of the receiving groove 111 to accommodate the film 3, the first installation grooves 112 can limit the film 3, so that the central axis on the film 3 can be aligned with the central axis of the receiving groove 111, so that the two ends of the optical fiber 2 in the receiving groove 111 can extend on the film 3 while remaining straight, And it is aligned with the central axis of the glue holding sheet 3 so as to be fixed with the glue holding sheet 3; at the same time, by arranging a movable first cover plate 12 on the base 11, the first cover plate 12 can be moved to the first position, pressing the optical fiber 2 against the two ends of the receiving groove 111, so that the optical fiber 2 is straightened, and cooperating with the receiving groove 111 to limit the optical fiber 2 so as to perform glue curing; when the first cover plate 12 moves to the second position, the first cover plate 12 is away from the receiving groove 111 so as to load the optical fiber 2 into the receiving groove 111 or take the optical fiber 2 out of the receiving groove 111.

[0038] The optical fiber dispensing and curing device 1 of the utility model, by arranging a receiving groove 111 on the base 11 to limit the non-dispensing part of the optical fiber 2, so that the non-dispensing part of the optical fiber 2 is limited, so that the optical fiber 2 can remain straight; at the same time, by respectively arranging first installation grooves 112 at both ends of the receiving groove 111 to accommodate the film 3 and limit the film 3, the central axis of the film 3 can be aligned with the central axis of the receiving groove 111, so that the optical fiber 2 in the receiving groove 111 is also aligned with the central axis of the film 3, so that the two ends of the optical fiber 2 can be fixed at the central axis position of the film 3, thereby improving the consistency of sample preparation; in addition, by arranging a movable first cover plate 12 on the base 11, the first cover plate 12 can be movable to fix the optical fiber 2 at the two ends of the receiving groove 111, so as to straighten the entire optical fiber 2, further ensuring that the optical fiber 2 can be aligned with the film 3 during the entire sample preparation process, improving the consistency of sample preparation, and effectively solving the problem that the optical fiber samples made in the prior art lack consistency and affect the reliability of the test results.

[0039] Optionally, the first cover plate 12 can be raised, lowered, rotated or slidably disposed on the base 11 so as to move between the first position and the second position. Figure 1 and Figure 2 As shown, the first cover plate 12 is rotatably disposed on the base 11 .

[0040] Optionally, in some embodiments, Figures 1 to 3 As shown, the base 11 includes a bottom plate 113 and an optical fiber stopper 114 . The optical fiber stopper 114 is detachably disposed on the bottom plate 113 , and an accommodating groove 111 is disposed on the optical fiber stopper 114 .

[0041] In this embodiment, the receiving groove 111 is set on the optical fiber stopper 114, and the optical fiber stopper 114 is detachably set on the bottom plate 113, so that the optical fiber stopper 114 can be replaced at any time. It is easy to understand that for optical fibers 2 of different sizes, in order to enable the optical fiber 2 to better fit with the plastic sheets 3 at both ends for glue fixation during sample preparation, optical fiber stoppers 114 of different specifications need to be set. Specifically, it is necessary to reasonably set the thickness of the optical fiber stopper 114 and the size (shape, width and depth, etc.) of the receiving groove 111, so that when the optical fiber 2 is located in the receiving groove 111, the part of the optical fiber 2 extending from the two ends of the receiving groove 111 is tangent to the surface of the plastic sheet 3. By setting a replaceable optical fiber stopper 114, the optical fiber glue curing device 1 of this embodiment can be applicable to the sample preparation process of optical fibers 2 of different sizes.

[0042] Specifically, Figure 4 and Figure 5 As shown, the receiving groove 111 may be a V-shaped groove, so as to cooperate with the first cover plate 12 to clamp and fix the optical fiber 2.

[0043] Optionally, in some embodiments, Figures 1 to 3 As shown, a second installation groove 115 adapted to the optical fiber stopper 114 is provided on the bottom plate 113 , and the optical fiber stopper 114 is disposed in the second installation groove 115 .

[0044] In this embodiment, a second mounting groove 115 is provided on the base plate 113 for mounting the optical fiber limiting member 114. The second mounting groove 115 can limit the optical fiber limiting member 114 so that the receiving groove 111 on the optical fiber limiting member 114 can be aligned with the film holding sheets 3 at both ends. At the same time, the optical fiber limiting member 114 can also be quickly disassembled and assembled on the base plate 113 so as to replace the optical fiber limiting member 114, thereby improving the efficiency of sample preparation.

[0045] like Figure 2 As shown, in some embodiments, a first slot body 116 is provided on the bottom plate 113 , and the first slot body 116 passes through the second installation slot 115 .

[0046] In this embodiment, by providing the first slot body 116 intersecting the second mounting slot 115, it is possible to ensure that the inner wall of the second mounting slot 115 is in close contact with the optical fiber stopper 114, and it is convenient to remove the optical fiber stopper 114 from the second mounting slot 115 when replacing the optical fiber stopper 114. For example, the optical fiber stopper 114 can be removed from the second mounting slot 115 by clamping the two sides of the optical fiber stopper 114 from the first slot body 116 by hand or with a clamping tool.

[0047] In a specific embodiment, Figure 2 As shown, the first slot body 116 is vertically arranged with the second mounting slot 115, the depth of the first slot body 116 is greater than the depth of the second mounting slot 115, and the depth of the overlapping portion of the first slot body 116 and the second mounting slot 115 is the same as the depth of the first slot body 116. When the optical fiber stopper 114 is placed in the second mounting slot 115, there is a gap below the optical fiber stopper 114 corresponding to the intersecting position of the two slots, which makes it easier to remove the optical fiber stopper 114 from the second mounting slot 115.

[0048] In some embodiments, Figure 2 and Figure 3 As shown, a first magnetic attraction portion 1141 is disposed on the optical fiber stopper 114 , and a second magnetic attraction portion 1151 is disposed in the second installation groove 115 at a position corresponding to the first magnetic attraction portion 1141 .

[0049] In this embodiment, by respectively arranging the corresponding first magnetic attraction portion 1141 and the second magnetic attraction portion 1151 in the optical fiber limiting member 114 and the accommodating groove 111, the first magnetic attraction portion 1141 and the second magnetic attraction portion 1151 can attract each other to fix the relative position of the optical fiber limiting member 114 and the second mounting groove 115, thereby avoiding relative displacement between the optical fiber limiting member 114 and the second mounting groove 115, which is beneficial to improving the stability of the sample preparation process, thereby further improving the consistency of the sample.

[0050] In some embodiments, Figure 2 As shown, a second slot body 117 is provided on the base 11 , and the second slot body 117 passes through the first installation slot 112 .

[0051] In this embodiment, by providing the second slot body 117 intersecting the first installation slot 112, it is possible to ensure that the inner wall of the first installation slot 112 is in close contact with the film sheet 3, and it is convenient to take the film sheet 3 out of the first installation slot 112 when replacing the film sheet 3. For example, the two sides of the film sheet 3 can be clamped from the second slot body 117 by hand or a clamping tool, so as to take the film sheet 3 out of the first installation slot 112.

[0052] In a specific embodiment, Figure 2 As shown, the second slot 117 is vertically arranged with the first mounting slot 112, the depth of the second slot 117 is greater than the depth of the first mounting slot 112, and the depth of the overlapping portion of the second slot 117 and the first mounting slot 112 is the same as the depth of the second slot 117. When the film 3 is placed in the first mounting slot 112, there is a gap below the film 3 corresponding to the intersecting position of the two slots, which makes it easier to take the film 3 out of the first mounting slot 112.

[0053] In some embodiments, Figure 2 As shown, the first installation groove 112 is provided with adjacent first inner wall 1121 and second inner wall 1122 , and the first inner wall 1121 and the second inner wall 1122 are respectively used to abut against adjacent two side edges of the film holding sheet 3 .

[0054] In this embodiment, the first inner wall 1121 and the second inner wall 1122 are provided so as to abut the adjacent side edges of the film receiving sheet 3 when installing the film receiving sheet 3, thereby positioning the film receiving sheet 3 so that the central axis of the film receiving sheet 3 and the central axis of the accommodating groove 111 can be aligned. The structure is simple, convenient and practical.

[0055] In a specific embodiment, Figure 2 As shown, an opening at one end of the accommodating groove 111 is located at the first inner wall 1121 , and the second inner wall 1122 is perpendicular to the first inner wall 1121 .

[0056] In some embodiments, Figure 1 and Figure 2 As shown, the optical fiber dispensing and curing device 1 also includes a second cover plate 13, which is movably arranged on the base 11, and the second cover plate 13 can move between a third position and a fourth position; in the third position, the second cover plate 13 is used to press the glue sheet 3 against the first mounting groove 112; in the fourth position, the second cover plate 13 is away from the first mounting groove 112 to loosen the glue sheet 3.

[0057] In this embodiment, a second cover plate 13 is provided on the base 11. When the second cover plate 13 moves to the third position, it can cooperate with the bottom of the first mounting groove 112 to clamp the film sheet 3 to fix the film sheet 3, thereby avoiding relative movement between the film sheet 3 and the first mounting groove 112 during the sample preparation process, so as to improve the stability of the film sheet 3 during the entire sample preparation process, thereby improving the consistency of the final sample.

[0058] Optionally, the second cover plate 13 can be raised, lowered, rotated or slidably disposed on the base 11 so as to move between the third position and the fourth position. Figure 1 and Figure 2 As shown, the second cover plate 13 is rotatably disposed on the base 11 .

[0059] Optionally, in some embodiments, Figure 2 As shown, a flexible gasket 121 is provided on one side of the first cover plate 12 facing the receiving groove 111 . When the first cover plate 12 is in the first position, the flexible gasket 121 is used to abut against the optical fiber 2 .

[0060] In this embodiment, a flexible gasket 121 is provided on the first cover plate 12. When the first cover plate 12 moves to the first position to press the optical fiber 2, the flexible gasket 121 abuts against the optical fiber 2. The flexible gasket 121 can deform itself while squeezing the optical fiber 2, thereby reducing the wear on the optical fiber 2 while fitting the optical fiber 2.

[0061] It is easy to understand that in some embodiments, Figure 2 As shown, a flexible gasket 121 is provided on one side of the second cover plate 13 facing the first installation slot 112. When the second cover plate 13 is in the third position, the flexible gasket 121 is used to abut against the film 3. In this embodiment, the technical effect of the flexible gasket 121 is similar to that of the previous embodiment, which will not be repeated here.

[0062] In some embodiments, Figure 2 As shown, the first cover plate 12 is provided with a third magnetic attraction portion 122 , and a fourth magnetic attraction portion 118 is provided on the base 11 at a position corresponding to the third magnetic attraction portion 122 .

[0063] In this embodiment, by respectively providing a third magnetic portion 122 and a fourth magnetic portion 118 on the first cover plate 12 and the base 11, when the first cover plate 12 moves to the first position, the third magnetic portion 122 can be attracted to the fourth magnetic portion 118 to fix the first cover plate 12 in the first position, thereby pressing the optical fiber 2 into the accommodating groove 111 for glue curing.

[0064] It is easy to understand that the second cover plate 13 is also provided with a third magnetic attraction portion 122, and correspondingly, the base 11 is also provided with a fourth magnetic attraction portion 118 at a position corresponding to the third magnetic attraction portion 122. When the second cover plate 13 moves to the third position, the third magnetic attraction portion 122 can be attracted to the fourth magnetic attraction portion 118 to fix the second cover plate 13 in the third position, thereby pressing the film 3 in the receiving groove 111 for dispensing and curing.
