[0001] The utility model relates to the technical field of optical fibers, in particular to an optical fiber single-filament clamp. Background Art

[0002] In some detection tests, it is necessary to use optical fiber monofilaments to stick to the workpiece to be detected. When sticking the optical fiber monofilament to the workpiece, since the outer wall surface of the optical fiber monofilament is coated, it is necessary to first remove part of the coating on the outer wall surface of the optical fiber monofilament by laser to expose the main body of the optical fiber monofilament, and then stick the exposed part of the optical fiber monofilament to the workpiece to be detected.

[0003] At present, the above operation is usually performed by an operator who manually cuts a certain length of optical fiber from a roll of optical fiber, places the optical fiber under a magnifying glass, and manually operates a laser to remove the outer coating of the optical fiber, and then adheres the optical fiber to the workpiece. However, during the above operation, since the optical fiber is extremely thin, it is difficult to fix it with a common clamp, and the optical fiber needs to be pressed and fixed on the operating table manually. However, when the optical fiber is manually operated by laser to remove part of the coating on the optical fiber, the optical fiber may rotate or roll on the operating table, making it difficult to ensure that the removed part of the coating remains in a straight line, which in turn causes the optical fiber to be unable to be effectively adhered to the workpiece through the exposed surface.

[0028] The following will be combined with the implementation of the utility model to clearly and completely describe the technical solutions in the implementation of the utility model. Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figure 1 As shown, combined Figure 4 , Figure 5 and Figure 6 The utility model discloses an optical fiber single-filament clamp, which comprises a base 1, a clamping part 2, a limiting member 3 and a movable platform 4.

[0030] The base 1 is a horizontal platform with a support column arranged thereon.

[0031] The clamping part 2 is arranged on the support column of the base 1, and the bottom end of the clamping part 2 has a smaller block-shaped end, and the side of the block-shaped end of the clamping part 2 is provided with an air suction port 201. The clamping part 2 is used to adsorb the optical fiber monofilament 10 on the side of the clamping part 2 through the air suction port 201, and make the optical fiber monofilament 10 horizontally arranged with the outer peripheral wall close to the side of the clamping part 2.

[0032] The limiting member 3 is disposed on the clamping portion 2 , and is used to limit the optical fiber monofilament 10 from being separated from the side of the clamping portion 2 .

[0033] The movable table 4 is disposed on the base 1 and moves relative to the base 1 toward or away from the clamping portion 2 . A workpiece 20 is disposed on the movable table 4 and is made to be in close contact with or detached from the outer peripheral wall of the optical fiber monofilament 10 .

[0034] When the above technical solution is adopted, a section of optical fiber filament 10 is pulled out from the rolled optical fiber filament 10, and the section of optical fiber filament 10 is adsorbed on the side of the clamping part 2 through the suction port 201; then the movable table 4 is pushed to drive the workpiece 20 to approach the clamping part 2. During this process, the workpiece 20 or the movable table 4 will resist and push the limit member 3 to move, so that the limit member 3 clamps the end of the optical fiber filament 10, thereby fixing the optical fiber filament 10; at the same time, the workpiece 20 will also contact the outer peripheral wall of the optical fiber filament 10, so that the operator can mark the area on the optical fiber filament 10 where the coating needs to be removed; push the movable table 4 backward to separate the workpiece 20 from the optical fiber filament 10, and then use a laser to remove the coating from the marked area, and then push the movable table 4 forward to bond the workpiece 20 to the exposed area on the optical fiber filament 10; finally, open the limit member 3, and remove the optical fiber filament 10 and the workpiece 20 from the fixture.

[0035] exist Figure 3 In a preferred embodiment shown, although the optical fiber filament 10 is adsorbed on the clamping part 2 by the suction cup of the suction port 201, the suction force of the suction port 201 is actually small, and it is difficult to avoid the optical fiber filament 10 from moving or rolling when the surface coating is removed by laser. Therefore, a first groove 202 is provided on the side of the clamping part 2, and both ends of the first groove 202 extend horizontally and are arranged through; the suction port 201 is provided on the bottom surface of the groove and is connected to the groove, so that the optical fiber filament 10 is adsorbed on the side of the clamping part 2 and arranged in the first groove 202. The suction port 201 adsorbs the optical fiber filament 10 in the first groove 202, and the first groove 202 limits the movement of the optical fiber filament 10 so that it does not shift in position.

[0036] exist Figure 3 In a preferred embodiment shown, it is necessary to push the movable table 4 to drive the workpiece 20 to approach the clamping portion 2, so that the workpiece 20 or the movable table 4 can be pressed against and push the limiting member 3 to move and clamp the optical fiber monofilament 10 during this process. Specifically, the limiting member 3 includes a fixing portion 31 and a clamping portion 32.

[0037] The two stoppers 3 are spaced apart at the two ends of the first groove 202 and are used to clamp the two ends of the optical fiber filament 10 .

[0038] The fixing part 31 is disposed on the clamping part 2, and a second groove 301 is provided on the side of the fixing part 31 contacting the optical fiber monofilament 10. The second groove 301 extends horizontally along both ends and is arranged through. The end of the second groove 301 facing the first groove 202 is connected to one end of the first groove 202, so that the optical fiber monofilament 10 is adsorbed on the side of the clamping part 2 and is simultaneously arranged in the first groove 202 and the second groove 301. The first groove 202 and the second groove 301 limit the position deviation of the optical fiber monofilament 10.

[0039] However, at this time, it is still impossible to avoid the possibility that the optical fiber filament 10 may rotate. One end of the clamping portion 32 is arranged on the fixing portion 31 and is located on one side of the extension direction of the second groove 301. The other end of the clamping portion 32 rotates around the fixing end and crosses the second groove 301 to be detachably connected to the fixing portion 31. The free end of the clamping portion 32 is detachably connected to the fixing portion 31, so that the end of the optical fiber filament 10 is clamped between the clamping portion 32 and the fixing portion 31.

[0040] Therefore, when the above technical solution is adopted, the movable table 4 drives the workpiece 20 to approach the clamping part 2, so that the workpiece 20 abuts and pushes the free end of the clamping part 32 to rotate, and the free end of the clamping part 32 is connected to the fixing part 31, and the clamping part 32 presses the optical fiber monofilament 10 into the second groove 301.

[0041] exist Figure 3 In a preferred embodiment shown, specifically, since the optical fiber filament 10 is a round filament, the radial cross-sectional shape of the first groove 202 is semi-elliptical, preferably semi-circular, so that the optical fiber filament 10 can be in close contact with the bottom surface of the first groove 202, and the suction port 201 can tightly absorb the optical fiber filament 10; and the radial cross-sectional shape of the second groove 301 is an isosceles triangle, which can make the outer peripheral wall of the end of the optical fiber filament 10 form three point contacts with the inner wall of the second groove 301 and the inner wall surface of the clamping portion 32, thereby clamping the optical fiber filament 10.

[0042] Therefore, when the above technical solution is adopted, the optical fiber filament 10 is adsorbed on the side of the clamping portion 2 and the outer peripheral wall of the optical fiber filament 10 is in close contact with the inner wall of the first groove 202 and the inner wall of the second groove 301 at the same time.

[0043] exist Figure 7 In a preferred embodiment shown, after the optical fiber filament 10 has completed the operation of removing the surface coating and sticking it to the workpiece 20, it is necessary to pry open the clamping portion 32 from the fixing portion 31 to release the end of the optical fiber filament 10. However, manually prying open the clamping portion 32 may cause the optical fiber filament 10 to bend and be damaged. Therefore, the limiting member 3 also includes a socket 33 and a pin 34.

[0044] At least one of the fixing portions 31 is spaced apart from the clamping portion 2 .

[0045] The socket 33 and the pin 34 are arranged between the fixing portion 31 and the clamping portion 2; the socket 33 is arranged on the clamping portion 2 and is located at one end of the first groove 202; the pin 34 is arranged on the fixing portion 31, and the pin 34 is detachably inserted into the socket 33, so there is no need to pry the clamping portion 32 apart from the fixing portion 31, and the optical fiber filament 10 pasted on the workpiece 20 can be more conveniently detached from the clamp by directly removing the limiting member 3, thereby avoiding the problem that the extremely fine optical fiber filament 10 may be damaged by manually prying the clamping portion 32 apart.

[0046] exist Figure 7 In a preferred embodiment shown in the figure, in order to prevent the limiting member 3 from axially rotating, the portion where the plug 34 is inserted into the socket 33 is square or triangular, and the plug 34 limits the fixing portion 31 from rotating relative to the socket 33 .

[0047] exist Figure 3 In a preferred embodiment shown, specifically, the free end of the clamping portion 32 is connected to the fixing portion 31 via a buckle structure. In addition, the clamping portion 32 may also adopt a wedge-shaped matching structure or other locking structures.

[0048] exist Figure 8 In a preferred embodiment shown, at least two suction ports 201 are provided on the side of the clamping portion 2 along the extension direction of the optical fiber filament 10, and each suction port 201 simultaneously sucks the optical fiber filament 10 and causes the optical fiber filament 10 to extend horizontally. The two suction ports 201 can form a more stable adsorption and fixation for the optical fiber filament 10, and enable the optical fiber filament 10 to be set horizontally.

[0049] exist Figure 8 In a preferred embodiment shown, during specific implementation, an air channel 203 is opened in the clamping portion 2, one end of the air channel 203 is connected to each suction port 201 at the same time, and the other end of the air channel 203 is connected to a vacuum pumping mechanism, so that the two suction ports 201 maintain the same adsorption force.

[0050] exist Figure 2 In a preferred embodiment shown, in order to facilitate the movement of the movable platform 4, a slide rail 5 is also included.

[0051] The slide rail 5 is horizontally arranged on the base 1, and the extending direction of the slide rail 5 is perpendicular to the extending direction of the optical fiber monofilament 10; the movable platform 4 is movably arranged on the slide rail 5 and moves along the slide rail 5. The slide rail 5 may be a T-shaped rail.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
