The U-shaped angle iron is used for fixing and is characterized in that: the distance between the two wing plates on the U-shaped angle iron is relatively fixed, uncertainty in the lens welding process is reduced, but the distance between the wing plates of the U-shaped angle iron needs to be matched with the lens, otherwise, the angle iron and the lens are easily subjected to cold welding or the lens cannot be installed on the angle iron, so that the angle iron and the lens are often fixed by friction force, namely, the lens is clamped by the angle iron and is integrally coupled, and then the lens is welded. However, this method requires high tolerances on the angle iron and also places high demands on the roughness of the lens-to-angle iron interface.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
Referring to fig. 1 to 3, a fixing assembly for fixing an optical coupling lens according to the present invention will now be described. The fixing assembly for fixing the optical coupling lens comprises a metal shell 1 and an angle iron assembly 2, wherein the optical coupling lens 3 is arranged on the metal shell 1, special-shaped grooves 4 are formed in two opposite outer side surfaces of the metal shell 1, and the arrangement positions of the special-shaped grooves 4 are away from the optical coupling lens 3; the angle iron assembly 2 is provided with two groups of protruding structures 5 which are respectively matched and slidably connected with the two groups of special-shaped grooves 4, the two groups of protruding structures 5 form a supporting unit suitable for supporting the metal shell 1, and the metal shell 1 can slide on the supporting unit and can be slidably adjusted relative to the assembly position of the angle iron assembly 2.
Compared with the prior art, the fixing component for fixing the optical coupling lens comprises a metal shell 1 and an angle iron component 2, the optical coupling lens 3 is arranged on the metal shell 1, the metal shell 1 is provided with a special-shaped groove 4, the angle iron component 2 is provided with two groups of protruding structures 5 which are respectively matched and slidably connected with the two groups of special-shaped grooves 4, and the assembling position of the metal shell 1 relative to the angle iron component 2 can be slidably adjusted, so that the technical problems that the requirement on the tolerance of the angle iron is high when the lens is fixedly connected with the angle iron in the prior art, the requirement on the roughness of the joint surface of the lens and the angle iron is high, and the fixing of the lens is relatively troublesome are solved.
By using the fixing assembly of the present invention, the optical coupling lens 3 is mounted on the front surface of the metal housing 1, and the arrangement of the shaped groove 4 does not affect the light transmission characteristics of the optical coupling lens 3. The pitch of the protruding structures 5 on the angle-iron assembly 2 is the same as the length of the optical coupling lens 3 with a tolerance of 0.01mm, and the metal housing 1 is made slidable on the protruding structures 5.
In some embodiments, referring to fig. 1 to 3, the shaped groove 4 is L-shaped, and includes a long side 41 and a short side 42, the length of the short side 42 is less than the length of the long side 41, one end of the short side 42 is through to the front or the rear of the metal shell 1, defining the through end of the short side 42 as a through end, and the protrusion 5 slides into or out of the shaped groove 4 from the through end. The protruding structure 5 slides in and slides out from the through end, so that the metal shell 1 and the angle iron assembly 2 are installed and connected in a matched mode, and the metal shell 1 and the optical coupling lens 3 can be adjusted in a sliding mode in the length direction of the long edge 41 of the special-shaped groove 4. The long side 41 and the short side 42 are arranged perpendicularly.
Specifically, when the metal shell 1 needs to be disassembled, the protruding structure 5 can be slid out from the through end. In general, the adjustment of the optical coupling lens 3 is performed in the length direction of the long side 41 of the shaped groove 4, i.e. the shaped groove 4 is configured to meet the requirement of adjusting the position of the optical coupling lens 3. The short edge 42 merely serves to provide a "slide gate" for sliding between the metal shell 1 and the angle iron assembly 2 and ensures that the metal shell 1 does not slide out of the "slide gate" during sliding in the vertical direction.
In some embodiments, referring to fig. 1 to 3, the metal housing 1 is rectangular, the shaped groove 4 is disposed on two opposite sides of the metal housing 1, the long side 41 is disposed along the height direction of the metal housing 1, the short side 42 is disposed along the width direction of the metal housing 1, and the penetrating end is located on the end of the metal housing 1 close to the optical coupling lens 3.
In the present embodiment, it can also be considered that the optical coupling lens 3 and the metal housing 1 are an integral structure, and the shaped groove 4 is disposed on the side portion of the optical coupling lens 3, and can realize the functions of mutual assembling and relative position adjustment of the optical coupling lens 3 and the angle iron assembly 2.

During assembly, the through end of the short edge 42 of the special-shaped groove 4 is contacted with the protrusion structure 5, the protrusion structure 5 can slide into the special-shaped groove 4 by pushing the metal shell 1, and then the metal shell 1 and the angle iron assembly 2 are integrally coupled. When the clamping jaws used in coupling clamp the metal shell 1 or the optical coupling lens 3, the angle iron assembly 2 moves along with the metal shell 1 or the optical coupling lens 3, and when the combined body of the metal shell 1, the optical coupling lens 3 and the angle iron assembly 2 is placed on the tube shell, the relative assembly position of the angle iron assembly 2 and the optical coupling lens 3 can be kept adjustable due to the fact that the angle iron assembly 2 can slide. The optical coupling lens 3 is clamped during welding, the action force of welding laser is mainly in the height direction of the angle iron assembly 2, the relative position of the angle iron assembly 2 and the optical coupling lens 3 cannot be influenced, and meanwhile, the movement speed of a clamping jaw (used for clamping the optical coupling lens 3) is limited, so that the optical coupling lens 3 cannot be twisted left and right or back and front and back to influence welding. That is, when the metal shell 1 is assembled with the angle iron assembly 2, the metal shell 1 has only freedom of movement in the vertical direction of the angle iron assembly 2.
In some embodiments, referring to fig. 1 to 3, the two sets of protrusion structures 5 are disposed on the inner side surface of the angle iron assembly 2 and are respectively adapted to be slidably connected with the two sets of special-shaped grooves 4, defining a connection line of the two sets of protrusion structures 5 as a rotation axis, the metal housing 1 can rotate around the rotation axis, and the protrusion structures 5 are hemispherical protrusions. The rotation axis is a virtual rotation axis, and is not an actual rotation axis, but may be considered as a rotation axis for the purpose of understanding, and the metal housing 1 and the optical coupling lens 3 together may rotate around the rotation axis.
The beneficial effects obtained by adopting the scheme are as follows:
1) The angle iron assembly 2 is integrally coupled with the metal shell 1 or the optical coupling lens 3, so that the degree of freedom of the optical coupling lens 3 in welding with the angle iron assembly 2 and the angle iron assembly 2 with a tube shell is effectively reduced, and the coupling positions before and after welding are easier to maintain;
2) Compared with the prior art, the manufacturing process of the angle iron assembly 2 is not complex, and the cost is lower;
3) The angle iron assembly 2 can effectively avoid the adsorption of magnetic elements such as isolators and the like on the angle iron assembly 2;
4) The angle iron assembly 2 is easier to remove from the optical coupling lens 3 before and after welding with relatively less damage to the side walls of the metal housing 1 than conventional L-or U-shaped angle irons.
In some embodiments, referring to fig. 1 to 3, the metal shell 1 can be limited on the angle iron assembly 2 by friction with the angle iron assembly 2; the metal shell 1 is provided with a containing groove suitable for containing the optical coupling lens 3, and the optical coupling lens 3 is arranged in the containing groove to realize fixed connection.
In the specific arrangement, the height of the two sets of protruding structures 5 is ensured to be consistent. The angle iron assembly 2 can clamp or assemble and couple the metal housings 1 or the optical coupling lenses 3 with different sizes (especially, lengths), and in some embodiments, referring to fig. 1 to 3, the angle iron assembly 2 includes a bottom plate 21 and two parallel support plates 22 vertically disposed, bottom ends of the two support plates 22 are connected to the bottom plate 21, and two sets of protruding structures 5 are respectively disposed on inner side surfaces of the two support plates 22. The bottom plate 21 is arranged perpendicular to the support plate 22, and the projection structure 5 is located at a position higher than the support plate 22. The length of the bottom plate 21 is greater than the height or length of the support plate 22, and the support plate 22 is disposed at a middle position of the bottom plate 21.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
