[0037] Traditional optical processing devices often have complex structures and low integration. They typically use different housings depending on the welding process, and due to variations in processes and product requirements, multiple different specifications and structures are needed, making flexible adjustment and adaptation difficult. Taking laser processing as an example, in precision laser processing scenarios, especially for welding small electronic components and micro / nano structures, existing housing architectures are difficult to adapt to the changing and highly integrated market demands.

[0038] Based on this, the present invention proposes an optical product housing 100.

[0039] Please see Figures 1 to 6 In one embodiment of this utility model, the optical product housing 100 includes at least one splicing part a, at least one beam splitter 2, and at least one reflector 3; each splicing part a includes multiple splicing blocks 1, each splicing block 1 having an adjacent first side surface 11 and a second side surface 12, and the first side surface 11 and the second side surface 12 are perpendicular to each other. The splicing block 1 also has a first inclined surface 14, which is adjacent to both the first side surface 11 and the second side surface 12, and is set at an angle to both sides. The splicing block 1 also has a first passage 15 and a light-refractive through-hole 16, the first passage 15 penetrating through the first side surface 11 and the second side surface 12, and the light-refractive through-hole 16. The light-permeable aperture 16 penetrates the first inclined surface 14 and is connected to the first passage 15; each beam splitter 2 has a second inclined surface 21 and a second passage 24. The second inclined surface 21 abuts against a portion of the first inclined surface 14 to press the beam splitter onto the first inclined surface 14. The second passage 24 penetrates the beam splitter 2 and passes through the second inclined surface 21. The second passage 24 of a portion of the beam splitter 2 is connected to the first passage 15 to connect two adjacent splicing parts a. The second passage 24 of the remaining beam splitter 2 is connected to the optical element; each reflector 3 has an abutting surface 31, which abuts against the remaining first inclined surface 14 to press the reflector onto the first inclined surface 14.

[0040] Please refer to the following: Figure 7 , Figure 8 as well as Figure 10The technical solution of this utility model uses multiple splicing blocks 1 to form a splicing part a. In two adjacent splicing blocks 1, the first side 11 of one splicing block 1 abuts and connects with the second side 12 of the other splicing block 1. Multiple first channels 15 are sequentially connected to form the main channel of the beam. The first inclined surface 14 of one of the splicing blocks 1 in the splicing part a fits against the second inclined surface 21 of a beam splitter 2 to form a first mating group. The refractive through-hole 16 in the first mating group is connected to the second channel 24 to form a beam splitting channel or a beam combining channel. By placing a beam splitter at the first inclined surface 14 and the second inclined surface 21, the function of beam splitting or beam combining can be achieved. Yes; the first inclined surface 14 of another splicing block 1 of splicing part a is attached to the abutting surface 31 of a reflector 3 to form a second mating group. By placing a reflector on the first inclined surface 14 and the abutting surface 31, the light path can be reflected, so that the light beam can propagate along the first path 15. Furthermore, by using splicing blocks 1 with different sizes of first path 15 and lenses, the size of the light path cross section can be changed. Thus, by using splicing blocks, beam splitters and reflectors in conjunction with lenses, multiple functions such as light path channel extension, reflection, beam splitting, beam combining and diameter changing can be achieved. Moreover, the integration difficulty is lower due to the three components of the same specification.

[0041] It should be noted that in some embodiments, "the first passage 15 penetrates the first side 11 and the second side 12" means that the first passage 15 is arranged in a tortuous manner, having a first segment and a second segment that are interconnected. The first segment penetrates the first side 11 perpendicularly, and the second segment penetrates the second side 12 perpendicularly. Obviously, the length directions of the first segment and the second segment are arranged at a certain angle. In a preferred embodiment, the first segment and the second segment are arranged perpendicularly, and the light-refractive through-hole 16 is opened at the connection between the first segment and the second segment. In other embodiments, the extension direction of the first segment is at a certain angle to the first side 11, and the extension direction of the second segment is at a certain angle to the second side 12. The first segment and the second segment are symmetrically arranged along the central axis of the light-refractive through-hole 16. This utility model does not limit the specific shape of the first passage 15, the second passage 24, and the light-refractive through-hole 16. The shape can be elliptical or circular, as long as it can realize the passage of light beam and lens installation.

[0042] Furthermore, the "connection" described in this utility model means that the light beam can pass through, and does not mean that the space is connected. Adding a sealing lens or other lens in its path is still considered as connection.

[0043] The splicing block 1 has various shapes. In one embodiment, the splicing block 1 is set as a triangular block shape, and in another embodiment, the splicing block 1 is set as a shape similar to a bent pipe.

[0044] When the splicing block 1 is set to a triangular block shape, the first side 11 and the second side 12 are perpendicular to each other. The surface adjacent to both the first side 11 and the second side 12 has three surfaces, two of which are perpendicular to the first side 11 and the second side 12, forming the third side 13. The remaining surface is inclined to the first side 11 and the second side 12, forming the first inclined surface 14. When the splicing block 1 is set to the shape of a bent pipe, the first side 11 and the second side 12 are the inlet or outlet of the bent pipe, respectively, and the first inclined surface 14 is the inclined surface formed by cutting at the bend.

[0045] Furthermore, "the second path 24 of some of the beam splitters 2 is connected to the first path 15 to connect two adjacent splicing parts a, and the second path 24 of the remaining beam splitters 2 is connected to the optical elements" means that in the beam splitters 2 of the multiple first matching groups, two adjacent splicing parts a are connected through beam splitters 2, while the remaining beam splitters 2 are used to connect optical elements such as light sources, imaging lenses, infrared temperature sensors, or splicing parts a.

[0046] Furthermore, "adjacent" means that the first side 11 and the second side 12 are close in position, and is not limited to the edges of the first side 11 and the second side 12 being in complete contact. A chamfered surface or a rounded corner surface may be formed between the first side 11 and the second side 12, or a surface such as... Figure 2 The groove shown.

[0047] Please see Figure 2 and Figure 3 To facilitate the installation of the splicing block 1, in one embodiment of this utility model, each splicing block 1 has two third side surfaces 13. Each third side surface 13 is adjacent to the first side surface 11, the second side surface 12, and the first inclined surface 14. The third side surface 13 is provided with a first clearance groove 131. The inner wall of the first clearance groove 131 is provided with a first connecting hole 132 and a second connecting hole 133. The first connecting hole 132 extends to the first side surface 11, and the second connecting hole 133 extends to the second side surface 12. The first side surface 11 is provided with a plurality of first mating holes 111 for connecting with the second connecting holes 133 of other splicing blocks 1 through screws. The second side surface 12 is provided with a plurality of first mating holes 111 for connecting with the first connecting holes 132 of other splicing blocks 1 through screws. Thus, by setting the first clearance groove 131 to allow the screw to be inserted from the first connection hole 132 or the second connection hole 133, the screw passes through the first connection hole 132 or the second connection hole 133 and is screwed into the first mating hole 111 on the first side 11 or the second side 12 of the adjacent splicing block 1. The installation is convenient and the installation method is simple, and the influence of the screw is avoided, minimizing the installation error of the two splicing blocks 1.

[0048] Furthermore, a through hole 143 is provided on the first inclined surface 14, and the through hole 143 extends to the first side surface 12 or the second side surface 11, so as to connect with the first mating hole 111 of other splicing blocks 1 through a screw connector. The through hole 143, the second connecting hole 133 and the first mating hole 111 together fix two adjacent connecting blocks.

[0049] Please refer to the following: Figure 4 and Figure 5 In one embodiment of this utility model, each beam splitter 2 also has a connecting surface 22. The connecting surface 22 is located on the side of the second inclined surface 21 away from a splicing part a, through which the second passage 24 passes. The connecting surface 22 is provided with a plurality of second mating holes 221 for connecting with the first connecting hole 132 or the second connecting hole 133 of the splicing block 1 by means of screws. In this way, by setting the connecting surface 22 to connect with one of the optical elements or the first side surface 11 or the second side surface 12 of the splicing part a, the connection between the splicing part a and the optical element, and between one splicing part a and another splicing part a, is realized.

[0050] Please refer to the following: Figure 8 , Figure 9 In one embodiment of the present invention, the first inclined surface 14 of one of the splicing blocks 1 of the splicing part a is fitted with the second inclined surface 21 of a beam splitter 2 to form a first mating group; the first inclined surface 14 is provided with a plurality of third mating holes 141; the beam splitter 2 also has a connecting surface 22 and a beam splitting side surface 23, the connecting surface 22 is located on the side of the second inclined surface 21 away from the splicing part a, for the second passage 24 to pass through, the beam splitting side surface 23 is adjacent to the second inclined surface 21 and the connecting surface 22, wherein: the beam splitting side surface 23 is provided with a plurality of second clearance grooves 231, the inner wall of each second clearance groove 231 is provided with a third connecting hole 232, the third connecting hole 232 extends to the second inclined surface 21, in the first mating group, the third connecting hole 232 is connected to at least a portion of the third mating holes 141 by a screw connector. Thus, by setting a second clearance groove 231 for the screw to be inserted from the third connecting hole 232, the screw passes through the second connecting hole 133 and is screwed into the third mating hole 141 of the splicing block 1 in the first mating group. The installation is convenient and the installation method is simple, avoiding the influence of the screw and minimizing the installation error of the two splicing blocks 1.

[0051] To reinforce the connection, a fourth connecting hole 222 is provided on the connecting surface 22, extending to the second inclined surface 21. The third connecting hole 232, the fourth connecting hole 222, and the second passage 24 are radially offset. In the first mating group, the fourth connecting hole 222 is connected to at least part of the third mating hole 141 by a screw connector. Thus, the screw connector passes through the fourth connecting hole 222 and is screwed into the third mating hole 141 of the splicing block 1 in the first mating group. The fourth connecting hole 222, the third connecting hole 232, and the third mating hole 141 together reinforce the connection of the first mating group.

[0052] Please see Figure 10 In one embodiment of this utility model, the first inclined surface 14 of another splicing block 1 in the splicing part a is attached to the abutting surface 31 of a reflector 3 to form a second mating group; the reflector 3 is provided with a plurality of fifth connecting holes 311. In the second mating group, the fifth connecting holes 311 and the third mating holes 141 are connected by screws. Thus, the screws pass through the fifth connecting holes 311 and are screwed into the third mating holes 141 of the splicing block 1 in the second mating group. The third mating holes 141 can be connected to the third connecting holes 232, the fourth connecting holes 222, and the fifth connecting holes 311 by screws. Each splicing block 1 can be adapted to the beam splitter 2 and the reflector 3, further improving the flexibility of the optical product housing 100.

[0053] In one embodiment of the present invention, the cross-sectional size of the second channel is gradually increased at least partially along the direction of the first inclined surface 14 near the splicing part a, in order to fix the beam splitter.

[0054] Please refer to the following: Figure 9 In one embodiment of this utility model, the abutting surface 31 of the reflector 3 is provided with a mounting groove. The cross-sectional size of the mounting groove gradually increases along the direction from the bottom of the groove to the opening of the groove, in order to fix the reflector.

[0055] Among them, "gradually increasing setting" includes various implementation methods such as increasing setting step by step and gradually increasing cross-sectional size, with the aim of being able to stably fix the beam splitter or reflector.

[0056] Please see Figure 3 and Figure 5 In one embodiment of this utility model, the first inclined surface 14 and the second inclined surface 21 are provided with pin holes 142 for installing pins to limit the beam splitter. In this way, the beam splitter or reflector can be stably fixed in the radial direction of the refractive through-hole 16.

[0057] Please see Figure 7 In one embodiment of this invention, each splicing part a is integrally formed. This reduces the assembly steps between splicing parts, thereby increasing installation speed.

[0058] In one embodiment of the present invention, the optical product housing 100 is further provided with a plurality of blind holes for fixing the optical product housing 100 to the installation position or fixing some optical components to the optical product housing 100.

Each beam splitter 2 has a first... Two inclined surfaces 21 and a second passage 24 are present. The second inclined surface 21 abuts against a portion of the first inclined surface 14 to hold the beam splitter against the first inclined surface 14. The second passage 24 passes through the beam splitter 2 and through the second inclined surface 21. The second passage 24 of a portion of the beam splitter 2 is connected to the first passage 15 to connect two adjacent splicing portions a. The second passage 24 of the remaining beam splitter 2 is connected to the optical element.

Each beam splitter 2 also has a connecting surface 22 located on the side of the second inclined surface 21 away from a splicing portion a, through which the second passage 24 passes. Multiple optical elements are respectively installed on at least one of the exposed first side surface 11, second side surface 12, and second inclined surface 21 of the optical product housing 100. Since the welding device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
