Description

Tool for cleaning optical fiber end face

Technical Field

The utility model belongs to the technical field of optical fiber cleaning, and particularly relates to a tool for cleaning an end face of an optical fiber.

Background

With the continuous progress of science and technology, the application of laser technology in the medical field is increasingly wide, including the application scenes in the aspects of laser diagnosis, laser treatment, laser surgery and the like. The optical fiber is used as an energy transmission channel of medical laser equipment and is used for carrying out accurate burning treatment on a focus part of a patient. As a convenient laser fiber connection mode, the fiber connector has been widely used in medical laser equipment. Generally, optical fiber connectors are all present in medical laser equipment in the form of optical fiber jumpers and the like, and these optical fiber jumpers often undergo multiple plugging and unplugging processes in the transportation, installation, debugging and maintenance processes. In this process, the fiber-optic endface is often contaminated due to an operator's lack of awareness of the endface of the connector or due to environmental factors. The foreign matters attached to the end face of the optical fiber not only can cause the failure of effective transmission of laser and influence the treatment effect, but also can absorb a large amount of laser energy to form a heat island and damage the optical fiber or the laser. And even serious medical accidents.

The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form a part hereof, and which together with the embodiments of the utility model serve to explain the principles of the utility model and not to limit its scope.

Example one

In one embodiment of the present invention, a tool for cleaning an endface of an optical fiber is disclosed, comprising: the optical fiber fixing interface 1 is used for fixing an optical fiber 3; the cleaning interface 2 is detachably arranged at the upper part of the optical fiber fixing interface 1, an optical fiber outlet 2-1 is arranged on the cleaning interface 2, and the optical fiber end face 3-2 of the optical fiber 3 is flush with the upper surface of the optical fiber outlet 2-1.

Specifically, the cleaning interface 2 and the optical fiber fixing interface 1 are in snap fit to realize connection and fixation. Snap-fit is a common connection means to facilitate connection and removal (not shown).

The end part of the optical fiber 3 is provided with an optical fiber interface 3-1, and the optical fiber interface 3-1 can be connected with a light source. When the optical fiber fixing connector is used, the optical fiber fixing connector 1 is sleeved on the optical fiber connector 3-1, and the optical fiber end face 3-2 of the optical fiber 3 extends out of the upper surface of the optical fiber fixing connector 1.

Specifically, the optical fiber 3 is connected with the optical fiber fixing interface 1 through the optical fiber interface 3-1, when the optical fiber interface 3-1 is an SMA905 interface, the outer side of the optical fiber interface 3-1 is provided with a fixing ring, the inner side surface of the fixing ring is provided with internal threads, correspondingly, the optical fiber fixing part 1-2 is arranged below the optical fiber fixing interface 1, and external threads are arranged outside the optical fiber fixing part 1-2, so that the optical fiber interface 3-1 is in threaded connection with the optical fiber fixing part 1-2.

Further, after the optical fiber 3 and the optical fiber fixing interface 1 are fastened and installed, the optical fiber end face 3-2 is higher than the upper surface of the optical fiber fixing interface 1; specifically, the end face 3-2 of the optical fiber is just 0.5mm-2mm higher than the upper end face of the optical fiber fixing interface 1.

Further, as shown in fig. 6, an air blowing pipe positioning groove 1-1 is formed on the upper end surface of the optical fiber fixing interface 1.

Further, the tool for cleaning the end face of the optical fiber also comprises an air tank 4, wherein the air tank 4 is a high-pressure air tank and can blow high-speed airflow through an air pipe 4-1.

The tool for cleaning the end face of the optical fiber has at least two use modes:

first, the optical fiber fixing interface 1 is used independently.

Secondly, the optical fiber fixing interface 1 is matched with the cleaning interface 2 for use.

Two modes of use are described below:

in a specific embodiment of the utility model, the optical fiber fixing interface 1 can be used independently, and is matched with the air pipe 4-1 of the air tank 4 to blow out high-speed air flow to blow and clean the optical fiber end face 3-2.

As shown in fig. 1 and 2, in the implementation:

an air pipe 4-1 of the air tank 4 is erected in an air blowing pipe positioning groove 1-1 of the optical fiber fixing interface 1, an air outlet of the air pipe 4-1 is flush with an optical fiber end face 3-2 of the optical fiber 3, and high-speed air flow blown out from the air pipe 4-1 can blow air to clean the optical fiber end face 3-2. That is, the air tube 4-1 on the air tank 4 (blowing device) is clamped on the blowing tube positioning groove 1-1 on the optical fiber fixing interface 1, and the air port position of the air tube 4-1 is just flush with the optical fiber end surface 3-2. At this time, when the air pipe 4-1 blows out the air with strong flow velocity, the easily cleaned pollutants such as dust on the optical fiber end face 3-2 can be taken away.

In another embodiment of the present invention, the gas tank 4 is preferably used for removing the foreign matter on the fiber end face 3-2, but a powerful air suction device may be used instead of the gas tank 4 to provide high-speed air flow by air suction to remove the foreign matter on the surface of the fiber end face 3-2.

Furthermore, when the foreign matter at the optical fiber port 3-2 has a certain viscosity and cannot be taken away by the gas with a strong flow velocity blown out by the air pipe 4-1, the special cleaning agent for the optical fiber can be used.

As shown in fig. 3, the optical fiber end face 3-2 is coated with an optical fiber cleaning agent 5 to clean foreign matter.

Further, after the optical fiber end face 3-2 is coated with the optical fiber cleaning agent 5, after a period of time of foreign matter dissolution, the dissolved foreign matter and the optical fiber cleaning agent 5 are removed together by the strong air pressure in the air pipe 4-1. In this usage, the optical fiber cleaning agent 5 and the foreign matter can be removed by wiping using a dust-free cloth or a dust-free paper.

Further, if relatively tough foreign matter remains, the foreign matter is removed by the film-forming type cleaning agent 6 and the cleaning interface 2.

Specifically, as shown in fig. 5, the cleaning interface 2 is a bottle cap type structure and can be sleeved on the upper end of the optical fiber fixing interface 1, an optical fiber outlet 2-1 is arranged in the middle of the cleaning interface 2, and a portion of the optical fiber interface 3-1 protruding out of the optical fiber fixing interface 1 is clamped in the optical fiber outlet 2-1. When the optical fiber fixing connector is used, the cleaning connector 2 is sleeved outside the optical fiber fixing connector 1, after the optical fiber 3 is fixed on the optical fiber fixing connector 1, the cleaning connector 2 is installed at the top end of the optical fiber fixing connector 1, and the upper surface of the cleaning connector 2 is flush with the optical fiber end surface 3-2 after installation is completed.

As shown in fig. 4, when cleaning with the film-forming type cleaning agent:

the optical fiber fixing connector 1 can be matched with the cleaning connector 2, a part of or the whole end face of the cleaning connector 2 is coated with the film-forming type cleaning agent 6, the film-forming type cleaning agent 6 is adopted to remove foreign matters on the surface of the optical fiber end face 3-2, and the film-forming type cleaning agent 6 is quickly separated from the optical fiber end face 3-2 by separating the cleaning connector 2 from the optical fiber fixing connector 1, as shown in fig. 7.

When the film-forming type cleaning agent is used, the polymer solution is brushed or sprayed on part of or the whole end face of the cleaning interface 2, a strong and tough film layer can be formed after the polymer solution is completely dried, and the film layer is easy to tear off and takes away pollutants such as dust, fingerprints and the like. In the utility model, after the film-forming type cleaning agent 6 is dried to form a film, the cleaning interface 2 is taken down so as to separate the film body of the film-forming type cleaning agent 6 from the optical fiber end face 3-2, thereby achieving the effect of removing foreign matters.

Specifically, after the film-forming type cleaning agent 6 is dried to form a film, the cleaning interface 2 needs to be peeled off from the optical fiber fixing interface, and at this time, because the contact area between the film-forming type cleaning agent 6 and the optical fiber end face 3-2 is small, the film-forming type cleaning agent 6 can peel off the surface of the optical fiber end face 3-2 along with the cleaning interface 2, and meanwhile, foreign matters on the optical fiber end face 3-2 are taken away.

Further, the film-forming type cleaning agent on the upper surface of the cleaning interface 2 is lifted up by the ejector pin to be peeled off from the cleaning interface 2. Compared with a cleaning mode of directly coating the film-forming type cleaning agent 6 on the end face 3-2 of the optical fiber, the time for manually stripping the cleaning agent film is saved, and difficult operations such as difficult tilting of the adhesive film and the like are avoided.

Note: the optical fiber cleaning agent 5 and the film-forming type cleaning agent 6 are both existing products, and can be selected by the skilled person according to the needs. In the above-described air-blowing cleaning, cleaning agent cleaning and film-forming type cleaning agent cleaning, they may be used alone or in any combination. Preferably, non-contact cleaning may be performed first, followed by contact cleaning.

Example 2

Based on the tool for cleaning an optical fiber end face according to embodiment 1, in order to facilitate cleaning of the film-forming cleaning agent 6 on the cleaning interface 2, a thimble 7 is disposed on the cleaning interface 2, and the thimble 7 is disposed in a thimble mounting hole 2-2 of the cleaning interface 2 and can move up and down relative to the cleaning interface 2, as shown in fig. 8. Preferred embodiments are described below.

Specifically, as shown in fig. 8, the thimble 7 includes: a disc portion, a cylindrical portion, and a hexagonal tightening portion. The disc portion is arranged at the upper end of the cylindrical portion, the hexagonal screwing portion is arranged at the lower end of the cylindrical portion, the diameter of the disc portion is larger than that of the cylindrical portion, and the width of the hexagonal screwing portion is larger than that of the cylindrical portion.

Further, the cylindrical part is an optical axis cylinder, or the outer surface of the cylindrical part is provided with an external thread.

Referring to fig. 8 again, the thimble mounting hole 2-2 is a stepped hole, and the stepped hole includes an upper smooth surface hole and a lower threaded hole; the smooth surface hole can be fitted with the disk portion.

When the cylindrical portion is an optical axis cylinder, the ejector pin 7 can freely move up and down relative to the cleaning interface 2. When the cylindrical part is a threaded column, the cylindrical part is installed in a threaded hole of the thimble installation hole 2-2 through an external thread, and the thimble 7 can be rotated to move up and down relative to the cleaning interface 2.

When in use: the thimble can move up and down relative to the cleaning interface 2 by rotating the hexagonal screwing part at the lower end of the thimble 7, and when the film-forming type cleaning agent needs to be smeared, the thimble 7 moves down to enable the upper end surface of the thimble 7 to be flush with the upper end surface of the cleaning interface 2; when the film-forming type cleaning agent 6 which is dried to form a film is required to be separated from the cleaning interface 2, the ejector pin 7 rotates upwards to enable the disc part of the ejector pin 7 to protrude out of the upper surface of the cleaning interface 2, so that one side of the film-forming type cleaning agent 6 which is dried to form a film is jacked up, a tearing opening is increased, and the film-forming type cleaning agent 6 is conveniently torn off from the upper surface of the cleaning interface 2.
