Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0043] This application provides a laser system, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0044] See Figure 1 In one embodiment, the laser system includes: a laser 1; an optical path housing 2 connected to the laser 1 via a first sealing connection component 5; a plurality of optical components 200 disposed inside the optical path housing 2; a galvanometer 3 connected to the optical path housing 2 via a second sealing connection component 6; and an air cleaning device 4 for supplying clean air to the optical path housing 2.

[0045] In this embodiment, by sealing the laser 1, the optical path housing 2, and the galvanometer 3 together, the airtightness of the housing can be ensured. By supplying clean air into the optical path housing 2 through the air cleaning device 4, the air inside the housing can be kept clean and dry, preventing contamination of optical components such as lenses and improving the stability of the laser system.

[0046] Optionally, the air cleaning device 4 includes: an air inlet connector 41, an oil mist separator 42, a micro-mist separator 43, a pressure reducing valve 44, an air dryer 45, a speed regulating valve 46, and an air outlet connector 47 connected in sequence; the optical path housing 2 is provided with an air inlet 21 for connecting to the air outlet connector 47, and a one-way valve 22 for air outlet.

The air inside the optical path housing 2 can be discharged through the one-way valve 22.

[0048] Furthermore, a temperature and humidity transmitter 29 can be installed on the optical path enclosure 2, which can be used to monitor the temperature and humidity inside the optical path enclosure in real time and trigger an alarm when the temperature and humidity are lower than the set value.

[0049] Furthermore, a desiccant pack is provided inside the optical path housing 2.

[0050] Optionally, the surfaces of the optical path housing 2 and the mounting parts of the internal optical components 200 can be anodized in their natural color to avoid the influence of material volatilization.

[0051] See Figure 2 Optionally, the optical path housing 2 includes: a bottom plate 23, several side plates 24 and a top plate 25; sealing strips 28 are provided at the connection points between the bottom plate 23 and each side plate 24, between the side plates 24 and adjacent side plates 24, and between the top plate 25 and each side plate 24.

[0052] In this embodiment, the optical path housing 2 can be sealed by slotting the corresponding plate material, pressing the silicone sealing strip 28, and then fixing it with screws.

[0053] See Figure 2 and Figure 3 In some application scenarios, the optical path housing 2 is connected to the tabletop using screws. Optionally, the base plate 23 is provided with several countersunk holes 26 for screw fixing; a sealing ring 27 is provided in each countersunk hole 26.

[0054] Optionally, to facilitate the assembly and disassembly of the housings, both the first sealing connection assembly 5 and the second sealing connection assembly 6 are detachable connection assemblies.

[0055] See Figures 4 to 6Preferably, the first sealing connection assembly 5 includes: a first fixing tube 51, installed on the side wall of the laser 1; a first receiving groove 511 is provided on the outer end face of the first fixing tube 51; a plug tube 52, the front end of which is used to insert into the first receiving groove 511, and the outer wall of the rear end is provided with an external thread 521; a first pressing tube 53, which is sleeved on the external thread 521 of the plug tube 52, and has an internal thread 531 inside, and the rear end of which is used to insert into the second receiving groove 241 on the side plate of the optical path housing 2; wherein, during installation, the first pressing tube 53 is screwed in the first direction, and the first pressing tube 53 and the plug tube 52 move in opposite directions through the cooperation of the internal thread 531 and the external thread 521, so that the front end of the plug tube 52 presses against the bottom surface of the first receiving groove 511 and the rear end of the first pressing tube 53 presses against the bottom surface of the second receiving groove 241.

[0056] Furthermore, both the front end face of the insertion tube 52 and the rear end face of the first pressure tube 53 are provided with sealing rings 100; the first receiving groove 511 is provided with an anti-rotation protrusion 5111 for preventing the insertion tube 52 from rotating, and the front end of the insertion tube 52 is provided with an anti-rotation notch 522 that matches the anti-rotation protrusion 5111.

[0057] Furthermore, the front end of the insertion tube 52 is a small-diameter end, and the rear end is a large-diameter end; the external thread is provided on the outer wall of the large-diameter end; the diameter of the hole at the front end of the first pressure tube 53 is larger than the diameter of the small-diameter end and smaller than the diameter of the large-diameter end; a sealing ring 100 that fits with the inner hole of the front end of the first pressure tube 53 is provided on the outer wall of the small-diameter end.

[0058] In this embodiment, the insertion tube 52 and the first pressure tube 53 constitute a telescopic connection assembly, which can be extended and retracted by rotating the first pressure tube 53. When extended, it can connect the laser 1 and the optical path housing 2. When shortened, it can be disassembled between the laser 1 and the optical path housing 2, so as to facilitate the separate disassembly and maintenance of the laser 1 and the optical path housing 2.

[0059] In one application scenario, after fixing both the laser 1 and the optical path housing 2 onto the table, the front end of the connector 52 is inserted from the rear end of the first pressure tube 53 and protrudes from the front end of the first pressure tube 53. The front end of the connector 52 is then inserted into the first receiving groove 511, and the anti-rotation protrusion 5111 is inserted into the anti-rotation notch 522. The first pressure tube 53 is rotated in the first direction, causing it to gradually push into the second receiving groove 241 until the front end of the connector 52 presses against the bottom surface of the first receiving groove 511 and the rear end of the first pressure tube 53 presses against the bottom surface of the second receiving groove 241, thus completing the installation. Disassembly can be performed in the opposite direction to the first direction (e.g., clockwise) (e.g., counterclockwise).

[0060] Further, see Figure 7The second sealing connection assembly 6 includes: a second fixing tube 61, the front end of which is mounted on the galvanometer seat 31 of the galvanometer 3, and a convex ring 611 is provided in the middle; a second pressing tube 62, the front end of which is sleeved on the convex ring 611 and threadedly engaged with the convex ring 611, and a sealing ring 100 that engages with the rear end of the second fixing tube 61 is provided inside the rear end; and a sealing ring 100 that engages with the side plate of the optical path housing 2 is provided on the rear end surface of the second pressing tube 62.

[0061] In one application scenario, during installation, the second pressure tube 62 is first fitted onto the protruding ring 611 of the second fixing tube 61. Then, the front end of the second fixing tube 61 is fixedly installed on the galvanometer mount 31 of the galvanometer 3. The second pressure tube 62 is rotated until it is pressed tightly against the side plate of the optical path housing 2, thus completing the installation. During disassembly, the second pressure tube 62 only needs to be twisted in the reverse direction.

[0062] In summary, the laser system of this invention improves the working environment of the optical path through the combination of multiple sealing structures and an air cleaning device, thereby enhancing the stability of laser processing. It reduces the risk of personnel needing to readjust the optical path, saves time spent on-site cleaning, and increases production capacity.
