Description

Technical Field

[0001] The utility model relates to the technical field of synchronous laser welding equipment, in particular to a synchronous laser welding optical fiber locking structure. Background Art

[0002] The optical fiber involved in synchronous laser welding is different from the conventional optical fiber structure. The optical fiber of synchronous laser is arranged more densely on the mold.

[0003] In this regard, the patent with announcement number CN220427195U discloses an end locking structure for synchronous laser welding of combined beam branched optical fibers, which includes an optical fiber fixing plate, a welding optical fiber, an expansion rubber ring and a fastening component. The main principle is to squeeze the rubber ring through the fastening component to expand it, so that the rubber ring and the optical fiber are in an interference fit state. By increasing the friction on the side of the optical fiber structure, the optical fiber can be maintained at a height and relative position in the mold cavity, forming a stable locking structure, and can effectively save fixed space to meet the synchronous laser welding needs of dense optical fiber arrangement structures. However, actual research and use have found that although it can lock the optical fiber by squeezing the expansion of the rubber ring, due to the dense arrangement of the optical fibers, two optical fibers will be locked at the same time during locking, and one-to-one locking cannot be achieved. In addition, relying on the extrusion, deformation and expansion of the elastic rubber ring to fix the optical fiber cannot ensure the size and consistency of the locking force of each optical fiber.

[0004] For another example, the patent with publication number CN220207947U discloses a structure for fixing and installing PCR optical fibers, including a mounting plate, a pressure plate, an elastic ring, and a locking member. The pressure plate is provided with a first through hole for the optical fiber to pass through, the mounting plate is provided with a second through hole for the optical fiber to pass through, the elastic ring is sleeved on the outer periphery of the optical fiber, and the elastic ring is located between the pressure plate and the mounting plate. When installing the optical fiber, it first passes through the first through hole of the pressure plate, the elastic ring, and the second through hole of the mounting plate in sequence, and then the pressure plate is locked on the mounting plate. The pressure plate applies an extrusion force to the elastic ring. After the elastic ring is deformed by pressure, the inner ring becomes smaller and is tightly clamped to the outer periphery of the optical fiber, effectively preventing the optical fiber from falling out of the second through hole of the mounting plate; there is no need to use AB glue, and the optical fiber is fixed by pure physical action, which is convenient to install and can be repeatedly disassembled and assembled later, saving installation time and reducing manufacturing costs. However, actual research and use have found that it also relies on the pressure plate to squeeze the elastic ring, and uses the elastic ring to become smaller when it is compressed and deformed to lock the optical fiber. However, for densely arranged optical fibers, for example, when the optical fiber spacing is 1-2mm, there is not enough space to put the elastic ring around the outer periphery of the optical fiber.

[0005] Therefore, in view of some problems existing in the synchronous laser welding optical fiber locking structure conventionally used in the prior art, it is necessary to further optimize its structure. Utility Model Content

[0016] In an optional implementation manner of the utility model, the fixing hole is a circular hole; and

[0017] The locking hole is a waist-shaped hole, and the long axis direction of the waist-shaped hole is perpendicular to the axis of the optical fiber arranged in the corresponding optical fiber fixing hole.

[0018] In an optional implementation manner of the utility model, the locking hole and the locking threaded hole are fastened together by a locking screw;

Moreover, since the locking structure adopting this structure is a one-to-one locking method, even for multiple densely arranged optical fibers, it only needs to adjust the width of each locking spring piece accordingly to make the locking spring pieces corresponding to adjacent optical fibers not interfere with each other.

[0033] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 5 As shown, this embodiment provides a synchronous laser welding optical fiber locking structure, including: a practical optical fiber 2 fixing component and a locking component.

[0035] Next, specifically, the optical fiber 2 fixing assembly includes a fixing seat 1, a recessed cavity 1-5 body formed on the fixing seat 1, and a plurality of optical fiber fixing holes 5-11-3 arranged side by side on a side wall of the recessed cavity 1-5 body; each optical fiber fixing hole 5-11-3 is formed with an arc-shaped notch on the side end facing the recessed cavity 1-5 body. The fixing seat 1 here can optionally adopt a regular shape structure, such as but not limited to a rectangular parallelepiped structure, for which the cross-section of the recessed cavity 1-5 body can be selected to be rectangular, and the length direction of the rectangular recessed cavity 1-5 body is consistent with the length direction of the rectangular fixing seat 1, thereby improving the effective utilization rate of the space of the fixing seat 1.

[0036] Based on the above situation, it should be noted that the arc-shaped notch here can occupy 1 / 4 to 1 / 2 of the circle, and the arc-shaped notch is designed to cooperate with the locking component to achieve locking of the optical fiber 2.

[0037] Based on the above structure, each optical fiber 2 can be vertically inserted into the optical fiber fixing hole 5-11-3, and part of the outer wall of the optical fiber 2 is exposed at the arc-shaped notch.

[0038] What is to be described next is the locking assembly, which includes a group of locking holes 5-2 arranged on the bottom wall of the recessed cavity 1-5 body, which correspond one-to-one to a plurality of optical fiber fixing holes 5-11-3, and a plurality of locking spring pieces 5 used for one-to-one fastening cooperation with the group of locking holes 5-2; each locking spring piece 5 is formed with an abutting portion suitable for abutting the outer surface of the optical fiber 2 in the optical fiber fixing hole 5-11-3.

[0039] In more detail, the locking spring 5 is made of metal material, such as copper, iron, steel, etc.

[0040] Furthermore, in order to effectively ensure the locking effect of the locking spring piece 5 on the optical fiber 2, an optional implementation is given as an example in conjunction with the attached drawings. The locking spring piece 5 includes a connecting piece for being fastened to the locking hole 5-2 group, and a fin connected to the connecting piece by bending; the abutment portion is formed on the fin.

[0041] It should be noted that each locking hole 5-2 group includes two locking holes 5-2 that are spaced apart, one of which is a fixed threaded hole 1-1, and the other is a locking threaded hole 1-2. Correspondingly, the connecting piece is provided with a fixing hole 5-1 for matching with the fixing threaded hole 1-1 and a locking hole 5-2 for matching with the locking threaded hole 1-2. Specifically, the fixing hole 5-1 is a circular hole; and the locking hole 5-2 is a waist-shaped hole, and the long axis direction of the waist-shaped hole is perpendicular to the axis of the optical fiber 2 provided in the corresponding optical fiber fixing hole 5-11-3.

[0042] On the basis of the above structure, the locking hole 5 - 2 and the locking threaded hole 1 - 2 are fastened together by a locking screw 4 ; the fixing hole 5 - 1 and the fixing threaded hole 1 - 1 are fastened together by a fixing screw 3 .

[0043] Based on the above situation, the structure of the locking spring 5 can also be deformed as follows:

[0044] The connecting piece includes a first substrate with a fixing hole 5-1 and a second substrate with a waist-shaped hole; the first substrate and the second substrate are bent to form an obtuse angle, and the obtuse angle faces away from the bottom wall of the concave cavity 1-5; and the fin is bent and connected to the second substrate. The connecting piece under this structure has better elasticity, so that it can better achieve the locking effect on the optical fiber 2.

[0045] In addition, in order to prevent the locking spring 5 from abutting against the optical fiber 2 and causing damage to the surface of the optical fiber 2, the present embodiment also has the following design:

[0046] Firstly, an end of the fin away from the connecting piece is provided with an extension piece bent toward one side of the connecting piece; an arc-shaped corner is formed between the extension piece and the fin, and secondly, an arc-shaped corner is formed between the fin and the connecting piece.

[0047] In summary, regarding the synchronous laser welding optical fiber locking structure of this embodiment, its specific implementation principle is as follows:

[0048] When locking the optical fiber 2, firstly, pass the fixing screw 3 through the fixing hole 5-1 on the locking spring piece 5, lock it into the fixing threaded hole 1-1, and fix one end of the locking spring piece 5 on the fixing seat 1. Secondly, insert the optical fiber 2 into the optical fiber fixing hole 5-11-3, and after determining the position of the optical fiber 2, pass the locking screw 4 through the locking hole 5-2 on the locking spring piece 5, and lock it into the locking threaded hole 1-2, so that the locking spring piece 5 is deformed by the downward pressure of the locking screw 4, and one end of the fin connecting the extension piece of the locking spring piece 5 generates elastic force due to deformation, and the optical fiber 2 is pressed by the elastic force to fix the optical fiber 2. If the upper and lower positions of the optical fiber 2 are to be adjusted, just loosen the locking threaded hole 1-2, and the locking spring piece 5 restores its shape, and the position of the optical fiber 2 can be adjusted.
