Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber welding auxiliary equipment, in particular to an optical cable calibration device for an optical fiber fusion splicer. Background Art

[0002] Fiber fusion splicer is an important equipment or tool used in the production of fiber optic communication, fiber optic sensor and fiber optic laser equipment. It is mainly used for the construction and maintenance of optical cables in optical communication. The general working principle is to use high-voltage arc to melt the two fiber sections and use high-precision motion mechanism to smoothly push the two optical fibers into one to achieve the coupling of fiber mode field.

[0003] When using traditional welding equipment, the optical fiber needs to be manually clamped during the welding process. Once the clamping device is not placed properly, or the optical fiber is not placed properly, the two optical fibers will not be accurately connected. In addition, if the optical fiber outside the optical fiber fusion splicer is accidentally touched and pulled during the welding process, the optical fiber will move outward, causing the fusion splice to break and dislocate, affecting the normal welding operation.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-5 A cable calibration device for an optical fiber fusion splicer comprises a welding base plate 1, a V-shaped groove 2 is provided on the top of the welding base plate 1, a support rod 3 is rotatably connected to the top of the welding base plate 1, an optical fiber line 4 is placed on the top of the welding base plate 1, a limiting rod 5 is movably sleeved in the inner cavity of the support rod 3, a sliding rod 6 is fixedly mounted on the outer wall of the support rod 3, a driving spring 7 is movably sleeved on the outer wall of the sliding rod 6, a moving platform 8 is movably sleeved on the outer wall of the sliding rod 6, a load-bearing wheel 9 is fixedly mounted on the outer wall of the moving platform 8, a rotating plate 10 is rotatably connected to the inner wall of the load-bearing wheel 9, a supporting spring 11 is fixedly mounted on the outer wall of the rotating plate 10, a roller 12 is movably sleeved on the outer wall of the load-bearing wheel 9, and a limiting groove 13 is provided on the inner wall of the roller 12.

[0022] By setting a slide bar 6 on the outer wall of the support rod 3 and a drive spring 7 on the outer wall of the slide bar 6, the roller 12 can better fit the outer wall of the optical fiber line 4 under the action of the drive spring 7, so that the optical fiber line 4 can have better stability during welding under the action of the roller 12.

[0023] In a preferred embodiment, the static length of the driving spring 7 matches the length of the sliding rod 6 , and the outer wall diameter of the limiting rod 5 matches the inner wall diameter of the supporting rod 3 .

[0024] By setting the driving spring 7 on the outer wall of the slide bar 6, the moving platform 8 will descend along the outer wall of the slide bar 6 under the action of the driving spring 7. In the process of the moving platform 8 moving downward, the outer wall of the roller 12 can better contact the outer wall of the optical fiber line 4, so that the outer wall of the optical fiber line 4 is more stable when moving on the top of the V-groove 2.

[0025] In a preferred embodiment: a slide groove is formed on the outer wall of the support rod 3, a fixing rod is fixedly mounted on the outer wall of the limiting rod 5, and the distance between the outer wall diameter of the fixing rod and the inner wall of the slide groove is equal.

[0026] By opening a slide groove on the outer wall of the support rod 3, the fixing rod slides along the slide groove, so that the limiting rod 5 can be better extended and retracted in the inner cavity of the support rod 3, so that when the limiting rod 5 is pulled out from the top of the welding base plate 1, it can be retracted into the inner cavity of the support rod 3.

[0027] In a preferred embodiment: a limiting hole is opened on the top of the welding base plate 1 , and the inner wall diameter of the limiting hole is equal to the outer wall diameter of the limiting rod 5 .

[0028] By setting a limiting hole on the top of the welding base plate 1, when the top of the support rod 3 is directly above the optical fiber line 4, the outer wall of the limiting rod 5 can enter the inner cavity of the limiting hole, thereby locking the support rod 3 and preventing the support rod 3 from moving during use.

[0029] In a preferred embodiment, one end of the support spring 11 away from the rotating plate 10 is connected to the inner wall of the load-bearing wheel 9 , and the inner wall diameter of the roller 12 matches the outer wall diameter of the load-bearing wheel 9 .

[0030] By arranging the rotating plate 10 and the supporting spring 11 in the inner cavity of the load-bearing wheel 9, the rotating plate 10 will enter the inner cavity of the limiting groove 13 under the action of the supporting spring 11. At this time, the roller 12 can only move along the direction of compressing the supporting spring 11 and can only move in one direction, so that the optical fiber line 4 can only move inward and cannot move outward.

[0031] In a preferred embodiment: the outer wall of the roller 12 is fixedly equipped with an anti-skid pad, and the support rod 3 and the limit rod 5 are made of stainless steel.

[0032] By setting the anti-slip pad on the outer wall of the roller 12, the optical fiber line 4 needs to move along the V-groove 2 during the welding process. At this time, under the action of the roller 12, the optical fiber line 4 can only move inward along the outer wall of the V-groove 2 and cannot move outward, thereby better ensuring the stability of the optical fiber line 4 during the welding process.

[0033] Working principle: During the use of the above-mentioned equipment, when the equipment is needed to assist in the welding of the optical fiber line 4, the limit rod 5 is first lifted upward, and then the support rod 3 can be rotated to make the support rod 3 move away from the top of the V-shaped groove 2, and then the optical fiber line 4 can be placed on the top of the V-shaped groove 2, and the support rod 3 is rotated again to make the support rod 3 move as a whole to just above the V-shaped groove 2, and the limit rod 5 is inserted into the limit hole on the top of the welding base plate 1, and then the roller 12 can contact the outer wall of the optical fiber line 4 under the action of the driving spring 7, and play a certain fixing role on the optical fiber line 4 in the vertical direction. As the welding proceeds, the optical fiber line 4 needs to move inward. At this time, the optical fiber line 4 is pulled, and the roller 12 can move unidirectionally and can rotate unidirectionally under the action of pulling the optical fiber line 4 inward, but the optical fiber line 4 cannot be pulled outward. Under the action of the rotating plate 10, the roller 12 will be stuck in the reverse rotation, thereby better realizing the accuracy of the optical fiber line 4 during the welding process.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
