[0019] [The problem this disclosure aims to solve]

[0020] When removing the coating from fiber optic cores in a coating remover, the fiber optic cores are placed above a heater in the fiber mounting section. Furthermore, coating removal of fiber optic cores sometimes occurs in darkness. In darkness, it is sometimes difficult to visually identify the fiber optic cores placed in the fiber mounting section. When removing the coating from multiple fiber optic cores, such as intermittent bands, it is sometimes necessary to arrange the multiple fiber optic cores in the fiber mounting section to avoid breakage. Therefore, there is a need to improve the visual visibility of the fiber optic cores placed in the fiber mounting section.

[0021] [Effects of this disclosure]

[0022] According to this disclosure, the visual recognition of the optical fiber core wire placed in the optical fiber mounting section can be improved.

[0023] [Description of embodiments of this disclosure]

[0024] The following description will illustrate embodiments of the present disclosure. One embodiment of the coating removal device (1) includes: an optical fiber mounting section for mounting a coated optical fiber core, the optical fiber mounting section having a first cutting edge for cutting a notch in the coating; a cover section capable of being opened / closed relative to the optical fiber mounting section, having a second cutting edge opposing the first cutting edge when closed relative to the optical fiber mounting section; and a light diffusion section for irradiating diffused light onto the optical fiber core mounted in the optical fiber mounting section. The optical fiber mounting section has a mounting surface for mounting the optical fiber core, and the light diffusion section irradiates diffused light obliquely downward toward the mounting surface.

[0025] The coating remover has an optical fiber mounting section and a cover section. The optical fiber mounting section has a first blade that cuts a notch in the coating, and the cover section has a second blade opposite to the first blade. The optical fiber mounting section has a mounting surface for mounting a coated optical fiber core. The coating remover has a light diffusion section that irradiates diffused light onto the optical fiber core mounted on the mounting surface of the optical fiber mounting section. When the light diffusion section irradiates diffused light onto the optical fiber core, it can irradiate the optical fiber core without omission, compared to light with strong straightness, such as light from an LED. Therefore, the visual recognition of the optical fiber core mounted on the mounting surface can be improved. The light diffusion section irradiates diffused light obliquely downward toward the mounting surface of the optical fiber mounting section. When the diffused light is irradiated obliquely downward toward the mounting surface, the visual recognition of the optical fiber core mounted on the mounting surface can be improved compared to the case of horizontally irradiating diffused light.

[0026] (2) In (1) above, the light diffusion section may also be provided in a wall portion parallel to the optical fiber carrier, extending along the direction of the optical fiber core wire placed in the optical fiber carrier. The light diffusion section may also be disposed in a hole recessed in the wall portion in a direction away from the optical fiber carrier. In this case, the light diffusion section is disposed in a hole formed in the wall portion, thus preventing water or the like from entering the light diffusion section. Therefore, the diffusion section can be protected from the influence of moisture or the like.

[0027] (3) In (2) above, the light diffuser may also have a first protrusion protruding in the direction away from the optical fiber carrier and a second protrusion protruding downward, and the first and second protrusions may each enter the hole described above. In this case, the first and second protrusions of the light diffuser enter the holes of the wall, thereby making the light diffuser firmly fixed to the wall.

[0028] (4) In (2) or (3) above, the hole may also have a lower surface extending below the light diffuser, and the lower surface may extend obliquely downward as it leaves the light diffuser. In this case, even if water droplets or the like enter the hole, the water droplets or the like will flow obliquely downward along the lower surface as they leave the light diffuser and flow out of the hole. Therefore, the light diffuser can be protected from the influence of water droplets or the like.

[0029] [Details of the embodiments disclosed herein]

[0030] Hereinafter, specific examples of coating removers according to embodiments of the present disclosure will be described with reference to the accompanying drawings. The invention is not limited to these examples, but is shown in the claims and is intended to include all modifications within the scope of the claims. In the description of the drawings, the same or equivalent elements are labeled with the same reference numerals, and repeated descriptions are omitted where appropriate. For ease of understanding, parts of the drawings are sometimes simplified or exaggerated, and the scale, etc., are not limited to the description in the drawings.

[0031] Figure 1 This is a perspective view of a coating remover 1 according to one embodiment. Figure 2 This is a perspective view of a coating remover 1 equipped with an optical fiber holder H, wherein the optical fiber holder H holds the optical fiber core F to be coated by the coating remover 1. Figure 3 It means Figure 1 A perspective view of the internal structure of the coating remover 1 is shown. The optical fiber core F has, for example, a resin coating made of glass fiber and a coating of glass fiber.

[0032] The coating remover 1 is a device for removing the coating from optical fiber cores F. The diameter of the optical fiber core F (the outer diameter of the coating on the optical fiber core F) is, for example, 180 μm or more and 400 μm or less. The fiber holder H can hold multiple optical fiber cores F, and the coating remover 1 can remove the coating from multiple optical fiber cores F simultaneously. The multiple optical fiber cores F can be ribbon optical fiber cores such as intermittent band optical fibers.

[0033] For example, the coating removal device 1 includes a retainer holding portion 10 and a main body portion 20. The retainer holding portion 10 includes: a retainer mounting portion 11 for mounting an optical fiber retainer H that holds the optical fiber core F; and a cover portion 12 that can be opened / closed relative to the retainer mounting portion 11. The optical fiber retainer H holds the end of the optical fiber core F. The length of the portion of the optical fiber core F to be coated is adjusted by adjusting the position of the optical fiber retainer H holding the optical fiber core F. Hereinafter, the direction in which the cover portion 12 is closed to the retainer mounting portion 11 is defined as the first direction D1, and the direction in which the cover portion 12 is opened from the retainer mounting portion 11 is defined as the second direction D2. For example, the coating removal device 1 extends in the extension direction A, which is the direction in which the optical fiber core F extends, and has a width in a third direction D3, which is a direction that intersects both the first direction D1 and the second direction D2.

[0034] The retainer holding portion 10 and the main body portion 20 are arranged side by side along the extending direction A. The main body portion 20 is connected to the end of the retainer holding portion 10 along the extending direction A. The retainer holding portion 10 has a sliding shaft 13 extending to the main body portion 20. The retainer holding portion 10 has two sliding shafts 13, which are arranged side by side along the third direction D3. The main body portion 20 has a sliding hole for the retainer holding portion 10 to be inserted. The main body portion 20 has two sliding holes, which are arranged side by side along the third direction D3. The sliding shaft 13 is slidably inserted into the sliding hole formed in the main body portion 20. Thus, the retainer holding portion 10 can slide freely in the direction of approaching and leaving the main body portion 20. Hereinafter, the direction in which the retainer holding portion 10 leaves the main body portion 20 is sometimes referred to as front, forward, or front side, and the direction in which the retainer holding portion 10 approaches the main body portion 20 is sometimes referred to as rear, rearward, or rear side.

[0035] The retainer holding part 10 holds the fiber optic retainer H, which in turn holds the fiber optic core F. The retainer holding part 10 has a hinge 14 that allows the cover part 12 to be opened / closed relative to the retainer mounting part 11. The hinge 14 extends in the extension direction A at an end opposite to the third direction D3 of the retainer holding part 10. The cover part 12 rotates about the hinge 14, thereby opening / closing relative to the retainer mounting part 11. The retainer holding part 10 holds the fiber optic retainer H, which is mounted on the retainer mounting part 11, between the retainer mounting part 11 and the cover part 12.

[0036] The main body 20 has a coating removal section 22, which is the part where the coating of the optical fiber core F is to be removed, and an operation section 23, which operates the coating removal performed by the coating removal section 22. The coating removal section 22 and the operation section 23 are arranged side by side along the extending direction A. The coating removal section 22 is located between the operation section 23 and the retainer holding section 10. The coating removal section 22 has an optical fiber mounting section 24 for mounting the optical fiber core F and a cover section 25 that can be opened / closed relative to the optical fiber mounting section 24. The cover section 25 is closed toward the optical fiber mounting section 24 by moving in a first direction D1. The cover section 25 is opened from the optical fiber mounting section 24 by moving in a second direction D2.

[0037] The coating removal section 22 has a hinge 26 that allows the cover section 25 to be opened / closed relative to the optical fiber mounting section 24. The hinge 26 extends along the extension direction A at the end opposite to the third direction D3 of the main body section 20. The cover section 25 rotates about the hinge 26, thereby allowing the cover section 25 to be opened / closed relative to the optical fiber mounting section 24. The main body section 20 holds the optical fiber core F mounted in the optical fiber mounting section 24 between the optical fiber mounting section 24 and the cover section 25.

[0038] For example, the optical fiber mounting portion 24 has a side portion 24d facing a third direction D3 and a top portion 24c opposite to the closed cover portion 25. The optical fiber mounting portion 24 has a first blade 27 that cuts a notch in the coating of the optical fiber core F. The first blade 27 is disposed on the front side of the optical fiber mounting portion 24. The first blade 27 has, for example, a first blade portion 27b that cuts a notch in the coating and a support portion 27c that supports the first blade portion 27b. The first blade portion 27b and the support portion 27c are, for example, made of metal. The first blade portion 27b and the support portion 27c are integrally formed.

[0039] For example, the cover 25 has a side portion 25b facing the third direction D3 when closed, a top portion 25c facing the second direction D2 when closed, and an inner surface portion 25d opposite the top portion 24c of the fiber carrier portion 24 when closed. The cover 25 has a second blade 28 that cuts a notch in the coating of the fiber core F. The second blade 28 is disposed on the front side of the cover 25. When the cover 25 is closed to the fiber carrier portion 24, the second blade 28 is disposed at a position opposite to the first blade 27 along the first direction D1. The second blade 28 has a second blade portion 28b that cuts a notch in the coating and a support portion 28c that supports the second blade portion 28b. The second blade portion 28b and the support portion 28c are, for example, made of metal. The second blade portion 28b and the support portion 28c are integrally formed.

[0040] The first blade 27 and the second blade 28 are positioned opposite each other along the first direction D1 when the cover 25 is closed relative to the optical fiber mounting portion 24. A cut is made in the coating of the optical fiber core F located between the first blade 27b and the second blade 28b. The distance between the first blade 27b and the second blade 28b is set such that the first blade 27b and the second blade 28b will touch the coating of the optical fiber core F, but will not touch the glass fibers of the optical fiber core F.

[0041] The optical fiber mounting section 24 includes a heater 29. The heater 29 is positioned rearward of the first blade 27. For example, the heater 29 forms the mounting surface 24b of the optical fiber mounting section 24 on which the optical fiber core F is mounted. The heater 29 receives a power supply to heat the coating of the optical fiber core F. The power supply to the heater 29 is controlled by a heater energizing switch (not shown) that is turned on when the cover 25 is closed to the optical fiber mounting section 24 and turned off when the cover 25 is opened from the optical fiber mounting section 24. The heater 29 heats the optical fiber mounting section 24 when the cover 25 is closed to the optical fiber mounting section 24.

[0042] The operation unit 23 is located behind the coating removal unit 22. The operation unit 23 includes: a switch 23b for adjusting the power supply (on / off) or the temperature of the heater 29; and a display unit 23c showing the status of the heater 29 (e.g., the heating temperature of the heater 29 and its on / off state). The display unit 23c, for example, shows that the fiber optic core F has been heated by the heater 29, and the temperature of the fiber optic core F has reached the maximum temperature required for coating removal. For example, a battery (not shown) for supplying power to the heater 29 is built into the operation unit 23.

[0043] When removing the coating of optical fiber core F using the coating remover 1, the optical fiber core F is placed above the heater 29 of the optical fiber mounting section 24 (mounting surface 24b). Sometimes the removal of the coating of the optical fiber core F is performed in the dark, which may result in the optical fiber core F placed on the optical fiber mounting section 24 being difficult to see. When removing the coating of multiple optical fiber cores F, such as intermittent bands, it is sometimes necessary to arrange the multiple optical fiber cores F side-by-side along a third direction D3. The coating remover 1 of this embodiment improves the visual visibility of the optical fiber core F placed on the mounting surface 24b by having a light diffusion section 30. The light diffusion section 30 will be described in detail below.

[0044] Figure 4 This is a cross-sectional view of the light-diffusing portion 30 when cut along a plane extending in both the extending direction A and the first direction D1. (See figure) Figure 3 and Figure 4As shown, the light diffusion section 30 is provided on the wall section 40, which is parallel to the optical fiber mounting section 24 along the extension direction A. For example, the wall section 40 has a wall surface 41 opposite to the cover section 25 of the operation section 23. The wall surface 41 extends along a first direction D1 and a third direction D3.

[0045] The light diffuser 30 is disposed in a hole 42 recessed in the wall portion 40 in a direction away from the optical fiber carrier 24 (e.g., rearward). The hole 42 penetrates the wall portion 40, for example, in the extending direction A. The hole 42 has: an upper surface 42b extending from the wall surface 41 along the extending direction A and extending in both the extending direction A and the third direction D3; and a pair of inner surfaces 42c extending in both the first direction D1 and the extending direction A, and facing each other in the third direction D3. The hole 42 has: a lower surface 42d extending obliquely upward from the wall surface 41 and extending in the third direction D3; and an extending surface 42f extending from the end of the lower surface 42d opposite to the wall surface 41 along the extending direction A. The hole 42 is divided by the upper surface 42b, the pair of inner surfaces 42c, the lower surface 42d, and the extending surface 42f.

[0046] For example, the coating remover 1 includes a substrate 50 built into the operation unit 23. The substrate 50 is equipped with elements for processing electrical signals used to control various parts of the coating remover 1 in conjunction with operation of the operation unit 23. A light source 51 is mounted on the substrate 50. For example, the light source 51 is mounted on the upper surface 50b of the substrate 50. For example, the light source 51 is an LED light source that emits LED light. The operation unit 23 includes, for example, a light-on switch 23d for turning the light diffuser 30 on / off. As an example, the light-on switch 23d is a touch switch. For example, when the light-on switch 23d is turned on, the elements of the substrate 50 output a control signal to the light source 51. At this time, the light source 51 receives the control signal and emits light, illuminating the light diffuser 30 with light L1. As an example, light L1 is linear light.

[0047] For example, the light diffusion section 30 is made of acrylic acid or polycarbonate. As an example, the light diffusion section 30 contains diffusion particles that diffuse light L1. The light diffusion section 30 converts the light L1 from the light source 51 into diffused light L2, and illuminates the diffused light L2 onto the fiber core F mounted on the fiber carrier section 24. The light diffusion section 30 illuminates the diffused light L2 obliquely downward toward the mounting surface 24b of the fiber carrier section 24. The optical axis of the diffused light L2 extends obliquely downward from the light diffusion section 30 toward the mounting surface 24b.

[0048] For example, the optical axis of the diffused light L2 extends forward of the center of the extending direction A of the mounting surface 24b (the portion near the holder 10). In this case, the portion of the mounting surface 24b near the holder 10 can be brightened. As an example, the color of the diffused light L2 is milky white. For example, the light diffuser 30 is fixed to the upper surface 42b and contacts the extending surface 42f. For example, the light diffuser 30 is in close contact with the upper surface 42b and the extending surface 42f. In this case, water and the like can be prevented from entering the interior of the hole 42. As an example, the light diffuser 30 is fixed to the hole 42 via an adhesive member 33. The adhesive member 33 is, for example, double-sided tape. With the light diffuser 30 inside the hole 42, the lower surface 42d extends obliquely downward as it leaves the light diffuser 30.

[0049] Figure 5 This is a perspective view showing the light diffusion section 30 and the substrate 50. (Example) Figure 4 and Figure 5 As shown, the light diffusion section 30 has a first protrusion 31 protruding in a direction away from the optical fiber mounting section 24 and a second protrusion 32 protruding downward. The first protrusion 31 and the second protrusion 32 each enter a hole 42. The first protrusion 31 has: an upper surface 31b for mounting the adhesive member 33; an end face 31c extending from the end of the first protrusion 31 in the extending direction A in both the first direction D1 and the third direction D3; and a lower surface 31d facing the opposite direction to the upper surface 31b. The lower surface 31d faces the light source 51. The light source 51 is located below the lower surface 31d. The second protrusion 32 has: a first surface 32b facing the inner surface 43 of the wall section 40; an end face 32c extending from the lower end of the first surface 32b in both the extending direction A and the third direction D3; and a second surface 32d facing the opposite direction to the first surface 32b.

[0050] The substrate 50 has a recess 52 that is recessed in a direction away from the optical fiber mounting portion 24 (e.g., rearward). A portion of the light diffusion portion 30 enters the recess 52. For example, the light diffusion portion 30 has a stepped portion 34 mounted on the upper surface 50b of the substrate 50. The stepped portion 34 has: a first stepped surface 34b extending downward from the lower surface 31d of the first protrusion 31; and a second stepped surface 34c extending from the lower end of the first stepped surface 34b in both a direction close to the optical fiber mounting portion 24 (e.g., forward) and a third direction D3. The first stepped surface 34b is opposite to the light source 51 along the extending direction A. The first stepped surface 34b is the light incident surface into which light L1 enters from the light source 51. For example, the direction in which the optical axis of light L1 extends is consistent with the extending direction A. For example, the light diffusion portion 30 enters the recess 52 and is fixed to the substrate 50 with the second stepped surface 34c mounted on the upper surface 50b of the substrate 50.

[0051] Figure 6This is a front view of the light diffusion section 30 observed along the extension direction A. Figure 7 This is a rear view of the light diffuser 30. (As shown) Figure 5 , Figure 6 as well as Figure 7 As shown, when viewed along the extension direction A, the light diffusion section 30 is formed in a T-shape. For example, the light diffusion section 30 has an upper surface section 36 including a first protrusion 31, a side surface section 37 including a second protrusion 32, and a light emitting section 38 that emits diffused light L2. The upper surface section 36 extends in both the extension direction A and the third direction D3 and is formed into a plate shape with thickness in the first direction D1. The side surface section 37 extends downward from the end of the upper surface section 36 in the direction close to the optical fiber mounting section 24. The side surface section 37 extends in both the first direction D1 and the third direction D3 and is formed into a plate shape with thickness in the extension direction A.

[0052] The light emitting section 38 protrudes from the upper surface section 36 and the side surface section 37 toward the direction approaching the optical fiber carrier section 24. The light emitting section 38 extends along a third direction D3 and has an inclined surface 39 that slopes downwards relative to the first direction D1, exiting the optical fiber carrier section 24. The inclined surface 39 is the light emitting surface from which the diffused light L2 is emitted. Light L1, which enters the light diffuser section 30 from the first stepped surface 34b along the extending direction A, is transformed into diffused light L2 inside the light diffuser section 30, and the diffused light L2 is emitted obliquely downwards from the inclined surface 39 (see reference). Figure 4 As an example, inclined surface 39 is formed into a rectangular shape.

[0053] For example, the light emitting portion 38 has: an upper surface 38b extending from the upper surface portion 36 to the upper end of the inclined surface 39; a lower surface 38c extending from the side surface portion 37 to the lower end of the inclined surface 39; and a pair of side surfaces 38d connecting the upper surface 38b and the lower surface 38c. For example, the upper surface 38b and the lower surface 38c are formed into a rectangular shape. The pair of side surfaces 38d are arranged side by side along a third direction D3. For example, the side surfaces 38d are formed into a trapezoidal shape whose width narrows as they face downwards.

[0054] Next, the effects obtained from the coating remover 1 of this embodiment will be explained. The coating remover 1 has an optical fiber mounting section 24 and a cover section 25. The optical fiber mounting section 24 has a first blade 27 that cuts a notch in the coating, and the cover section 25 has a second blade 28 opposite to the first blade 27. The optical fiber mounting section 24 has a mounting surface 24b on which a coated optical fiber core wire F is mounted. The coating remover 1 has a light diffusion section 30 that irradiates diffused light L2 onto the optical fiber core wire F mounted on the mounting surface 24b of the optical fiber mounting section 24. When the light diffusion section 30 irradiates diffused light L2 onto the optical fiber core wire F, it can irradiate the optical fiber core wire F without omission, compared to light with strong straightness such as light from an LED. Therefore, the visual recognition of the optical fiber core wire F mounted on the mounting surface 24b can be improved. The light diffusion section 30 irradiates diffused light L2 obliquely downward toward the mounting surface 24b of the optical fiber mounting section 24. When diffused light L2 is irradiated obliquely downward toward the mounting surface 24b, the visual recognition of the optical fiber core F mounted on the mounting surface 24b can be improved compared with the case of horizontal irradiation of diffused light L2.

[0055] As described above, the light diffusion section 30 may also be provided in a wall portion 40 parallel to the optical fiber carrier 24 along an extending direction A that is the direction in which the optical fiber core F placed in the optical fiber carrier 24 extends. The light diffusion section 30 may also be disposed in a hole 42 recessed in the wall portion 40 in a direction away from the optical fiber carrier 24. In this case, the light diffusion section 30 is disposed in the hole 42 formed in the wall portion 40, thus preventing water and the like from entering the light diffusion section 30. Therefore, the light diffusion section 30 can be protected from moisture and other influences.

[0056] As described above, the light diffuser 30 may also have a first protrusion 31 protruding in the direction away from the optical fiber carrier 24 and a second protrusion 32 protruding downward, and the first protrusion 31 and the second protrusion 32 may each enter the hole 42. In this case, since the first protrusion 31 and the second protrusion 32 of the light diffuser 30 each enter the hole 42 of the wall portion 40, the light diffuser 30 can be firmly fixed to the wall portion 40.

[0057] As described above, the aperture 42 may also have a lower surface 42d extending below the light diffuser 30, and the lower surface 42d may extend obliquely downward as it leaves the light diffuser 30. In this case, even if water droplets or the like enter the aperture 42, the water droplets or the like will flow obliquely downward along the lower surface 42d and leave the light diffuser 30, and then flow out of the aperture 42. Therefore, the light diffuser 30 can be protected from the influence of water droplets or the like.

[0058] The embodiments of the coating remover disclosed herein have been described above. However, the present invention is not limited to the embodiments described above. Those skilled in the art will readily understand that the present invention can be modified and altered in various ways within the scope of the spirit of the claims. For example, the shape, size, quantity, material, and configuration of each part of the coating remover can be appropriately modified within the scope of the above spirit. For example, the shapes of the light diffusion part and the wall part are not limited to the shapes of the light diffusion part 30 and the wall part 40 described above, and can be appropriately modified.
