Description

Technical Field

[0001] The present invention relates to the technical field of devices for cutting optical fibers, and more particularly to an optical fiber cutting device with an observation system. Background Art

[0002] Before fiber fusion splicing, the fibers need to be cleaved to maintain the required smoothness and angle of the end faces on both sides of the splice. A fiber cleaver is a tool used for pre-splicing fiber fusion splices. A fiber cleaver cuts through high-strength steel to create a slit in the fiber, then breaks it with force.

[0003] Existing fiber cleavers simply perform a cutting operation and lack the ability to monitor the cutting quality and status. If placed directly on a splicer for inspection, if the cutting quality is poor, the fiber needs to be removed and re-cleaved, resulting in very low fiber splicing efficiency. Summary of the Invention

[0004] Features and advantages of the invention are set forth in part in the following description, or may be obvious from the description, or may be learned through practice of the invention.

[0005] The purpose of the present invention is to provide an optical fiber cutting device. By setting an imaging device and a display device, the side of the cut optical fiber can be observed, so as to evaluate the cutting effect, thereby avoiding the problem of optical fiber with poor cutting quality being placed in a fusion splicer for fusion splicing and then needing to be removed and re-cut, thereby increasing the efficiency of optical fiber fusion splicing.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an optical fiber cutting device, comprising a base and a cutting knife arranged on the base, and also comprising an imaging device and a display device, wherein the imaging device is used to photograph the blade of the cutting knife, and the display device is connected to the imaging device, and the display device is used to display the image captured by the imaging device.

[0007] The imaging device is directly opposite to the cutting edge of the cutting knife.

A mounting seat is provided on the base, and the mounting seat is arranged between the pair of second mounting plates. The mounting seat and the pair of second mounting plates are connected by a rotating shaft.

[0011] The imaging device includes a lens barrel, a lens, and a camera. The lens barrel is mounted on the cover body, the lens is mounted on one end of the lens barrel, and the camera is mounted on the other end of the lens barrel.

[0012] The imaging device further includes a light source mounted on the lens barrel, and light emitted by the light source enters the lens barrel.

[0013] The lens barrel comprises a lens barrel body and a connecting plate arranged on the lens barrel body, and the connecting plate is installed on the base.

[0014] The imaging device comprises a lens, and the central axis of the lens and the cutting edge of the cutting knife are in the same plane.

[0015] The central axis of the imaging device and the cutting edge of the cutting knife are in the same plane.

[0016] The present invention arranges an imaging device and a display device on the optical fiber cutting device. The imaging device is used to photograph the blade of the cutting knife. The imaging device can photograph the side of the cut optical fiber, and then output it to the display device for observation, so as to evaluate the cutting effect.

BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be described in detail below with reference to the accompanying drawings and in combination with examples, and the advantages and implementation modes of the present invention will become more apparent. The contents shown in the accompanying drawings are only used to illustrate the present invention and do not constitute any limitation to the present invention. In the accompanying drawings:

[0018] Figure 1 This is a schematic diagram of a fiber cutting device according to an embodiment of the present invention;

[0019] Figure 2 2 is a structural diagram of an optical fiber cutting device in an embodiment of the present invention. DETAILED DESCRIPTION

[0020] like Figure 1 and Figure 2As shown, the optical fiber cutting device with an observation system proposed in an embodiment of the present invention includes a base 1 and a cleaver 2, and the cleaver 2 is mounted on the base 1. The observation system includes an imaging device and a display device. The imaging device is used to photograph the blade of the cleaver, and the imaging device is used to photograph the side of the cut optical fiber. The display device is connected to the imaging device, and the display device is used to display the image captured by the imaging device. In this way, the imaging device can photograph the side of the cross-section of the cut optical fiber, and then output it to the display device for observation, so as to evaluate the cutting effect, avoiding the problem of having to remove the optical fiber for re-cleaving after the optical fiber with poor cutting quality is placed in the fusion splicer for fusion splicing, thereby increasing the efficiency of optical fiber fusion splicing.

[0021] In the present invention, the central axis of the imaging device and the blade 21 of the cutting knife 2 are in the same plane, so that the focus of the imaging device is the side of the cross section after the optical fiber is cut, so as to ensure clearer observation.

[0022] In the present invention, the blade of the cutting knife cuts the optical fiber. After the optical fiber is cut, the cross section of the optical fiber will be located at the blade edge. Therefore, by setting the central axis of the imaging device and the blade edge of the cutting knife in the same plane, the side of the cross section of the optical fiber after cutting can be clearly photographed, thereby judging whether the cut surface is flat, that is, the cut surface must be perpendicular to the central axis of the optical fiber.

[0023] refer to Figure 1 The solid circle in the figure is the cut surface on the optical fiber 3. When the optical fiber cutting device is working, the cutting knife cuts the optical fiber 3 at the solid circle. After cutting, since the central axis of the imaging device and the cutting edge of the cutting knife are in the same plane, the focus of the imaging device is the solid circle. Then the imaging device takes a picture of the solid circle and outputs it to the display device for display, so as to observe the side of the cross section of the cut optical fiber and evaluate the cutting effect.

[0024] In this embodiment, the display device is a display screen, and the display screen is connected to the imaging device via a data line.

[0025] In this embodiment, the imaging device is located directly above the cleaver during filming, enabling a clear and complete capture of the side surface of the cut optical fiber. Of course, the imaging device can also be located to the left or right of the cleaver, enabling the capture of the side surface of the cut optical fiber.

[0026] The imaging device is rotatably mounted on the base. In this embodiment, the optical fiber cutting device further includes a cover, which is rotatably mounted on the base, and the imaging device is mounted on the cover. The cover is an existing structure of the optical fiber cutting device, and its function is to press on the optical fiber to facilitate cutting of the optical fiber, otherwise the optical fiber cannot be cut. In the present invention, the imaging device is mounted on the cover, directly utilizing the existing structural components of the optical fiber cutting device to install the imaging device, eliminating the need for additional structural components and avoiding structural complexity. The imaging device can also be mounted directly on the base.

[0027] When cutting an optical fiber, the cover is rotated to cover the optical fiber, thereby severing the fiber. The imaging device is now located to the left or right of the cleaver, allowing for direct video and observation after severing the fiber. Alternatively, the cover can be rotated again to open it, with the imaging device now located directly above the cleaver, allowing for video and observation.

[0028] The cover body includes a cover plate 4, a first mounting plate 5, and a pair of second mounting plates 6. The first mounting plate 5 is located on one side of the cover plate 4, and the pair of second mounting plates 6 are spaced apart on the other side of the cover plate 4. A mounting seat 7 is provided on the base 1. The mounting seat 7 is located between the pair of second mounting plates 6 and is connected to the pair of second mounting plates 6 by a rotating shaft to facilitate the rotation of the cover body.

[0029] The imaging device includes a lens barrel 8, a lens 9, and a camera 10. The lens barrel 8 is mounted on the cover, the lens 9 is mounted on one end of the lens barrel 8, and the camera 10 is mounted on the other end of the lens barrel 8, with the lens 9 facing the cutting blade 2. The lens barrel 8 includes a lens barrel body 81 and a connecting plate 82. The connecting plate 82 is provided on the lens barrel body 81 and mounted on the first mounting plate 5. The connecting plate 82 and the first mounting plate 5 are connected by screws. In this way, when the cover rotates, it will drive the imaging device to rotate.

[0030] In this embodiment, the central axis of the lens 9 and the blade of the cutting knife 2 are in the same plane, and the blade is used to cut the optical fiber. In this way, the focus of the lens is the side of the cross-section after the optical fiber is cut, so the camera can capture the side of the cross-section of the cut optical fiber, and then display the image on the display screen connected to the camera for observation, so as to evaluate the cutting effect, avoiding the problem of optical fiber with poor cutting quality being placed in the fusion splicer for fusion splicing and then needing to be removed and re-cut, thereby increasing the efficiency of optical fiber fusion splicing.

[0031] The imaging device further includes a light source 11 mounted on the lens barrel body 81 of the lens barrel. Light emitted by the light source 11 enters the lens barrel 8, thereby achieving a better imaging effect.

For example, a feature shown or described as part of one embodiment may be used in another embodiment to yield yet another embodiment.
