[0004] Laser equipment that uses lasers as a medium to achieve processing or ranging purposes is becoming increasingly popular. Laser equipment such as laser engraving machines and laser marking machines can be used for laser processing. However, the laser processing environment usually has a lot of oil and dust. If dust adheres to the optical lens of the laser module's output port, it can easily affect the laser emission. If dust adheres to the processing position, it will also affect the laser processing process or the ranging accuracy. Utility Model Content

The heat dissipation fan is located in the accommodating cavity and above the laser module, and the air outlet of the heat dissipation fan is oriented towards the laser module.

[0022] And / or, the heat dissipation module includes a heat sink disposed on at least one side surface of the laser module, the heat sink being connected to the laser module, and the surface of the heat sink facing away from the laser module having a plurality of heat dissipation fins arranged side by side.

Furthermore, an air nozzle module is provided on the light-emitting mask. This air nozzle module forms a flow guide cavity and has an outlet communicating with the flow guide cavity. The outlet of the flow guide cavity is coaxially aligned with the light-emitting port of the laser module, allowing the laser to be emitted through the outlet. When processing with the laser of this application, the air nozzle module is connected to an air supply structure. The air supply structure supplies airflow to the air nozzle module, causing the airflow to sequentially pass through the air guide channel, the flow guide cavity, and the outlet before being blown outwards. This blows away dust and fumes outside the outlet, and the continuous airflow also prevents dust and other impurities from entering the flow guide cavity and then entering the light-emitting port of the laser module or adhering to the window mirror or focusing lens, thereby avoiding interference with laser emission. Furthermore, since the air nozzle module is fixed on the laser module, it can rise and fall together with the laser module, which ensures that the air nozzle module can always form an airflow at the front end of the laser module's air nozzle. It can also direct the airflow towards the processing position, preventing dust from sticking to the processing position, thus playing a good dustproof role and ensuring the processing effect.

[0032] By setting up an air guide channel in the air nozzle module to connect to the flow guide cavity, there is no need to set up an air pipe to connect to the light output position to supply air to the flow guide cavity. This reduces the use of air pipes and can hide the air path. There are no air pipes under the laser module, which can avoid the problem of air pipes easily interfering with other devices during laser processing, and makes the laser look neat and uniform.

[0070] This application proposes a laser 100.

[0071] Please refer to Figure 2 , Figure 8 as well as Figure 9In one embodiment of this application, the laser 100 includes a housing 10, a laser module 20, and a nozzle module 50. A receiving cavity 11 is formed inside the housing 10, and the bottom of the receiving cavity 11 has an opening. At least a portion of the laser module 20 is vertically and vertically disposed in the receiving cavity 11, and the light emission port 23 of the laser module 20 is disposed facing downward toward the opening. The nozzle module 50 is disposed below the laser module 20 and has a gas guiding channel 513, a flow guiding cavity 521, and an outlet 522. The flow guiding cavity 521 is connected to the gas guiding channel 522. The gas guiding channel 513 can be connected to a gas source and guide the airflow to the flow guiding cavity 521. After passing through the flow guiding cavity 521, the airflow is blown out from the outlet 522. The light emission port 23 of the laser module 20 is located inside the flow guiding cavity 521, and the center line of the outlet 522 coincides with that of the light emission port 23.

[0072] The laser 100 proposed in this application can be applied in laser equipment 1 such as laser marking machines, laser engraving machines, laser cutting machines, and laser welding machines to emit laser light for laser marking, laser engraving, laser cutting, and laser welding operations. The laser 100 includes a housing 10 serving as a support and mounting base. A receiving cavity 11 is formed within the housing 10, and an opening communicating with the receiving cavity 11 is provided at the bottom of the housing 10. At least a portion of the laser module 20 is disposed within the receiving cavity 11, and the laser module 20 is height-adjustable. Alternatively, the laser module 20 can be kept always within the receiving cavity 11, only moving within it, with the light output port 23 of the laser module 20 facing downwards from the opening of the receiving cavity to emit laser light. Or, the laser module 20 can be height-adjustable and enters and exits the receiving cavity 11 through the bottom opening of the housing 10. In either case, the height of the laser module 20 can be adjusted to adjust the height of the laser focal point, ensuring that the laser focal point falls on the processing position.

[0073] In addition, a nozzle module 50 is provided in the laser 100. The nozzle module 50 is located below the laser module 20. The nozzle module 50 has a gas guiding channel 513, a flow guiding cavity 521 and an outlet 522 connected in sequence. The light emission port 23 is located in the flow guiding cavity 521. The outlet 522 and the light emission port 23 are coaxially arranged so that the laser can be emitted through the outlet 522. When processing with the laser 100 in this embodiment, the nozzle module 50 can be connected to the air supply structure 300, which serves as the air source. The air supply structure 300 supplies airflow to the nozzle module 50, and the airflow provided by the air supply structure 300 is blown outward sequentially through the air guide channel 513, the guide cavity 521, and the outlet 522. This arrangement can blow away dust and smoke outside the outlet 522, and the continuous airflow can also prevent dust and other impurities from entering the guide cavity 521 and entering the light output port 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting laser emission. Furthermore, since the nozzle module 50 is fixed on the laser module 20, it can rise and fall together with the laser module 20, so that the nozzle module 50 can always form an airflow at the front end of the nozzle 52 of the laser module 20, and can also blow the airflow towards the processing position, preventing the processing position from being contaminated with dust, playing a good dustproof role and ensuring the processing effect.

[0074] In this embodiment, by setting an air guide channel 513 in the air nozzle module 50, it is not necessary to set an air pipe extending to the light output position and connecting it to the flow guide cavity 521. This can hide the air path, and there will be no air pipe under the laser module 20. This can avoid the problem of air pipes easily interfering with other devices during laser processing, and make the laser 100 look neat and uniform.

[0075] It should be noted that in this embodiment, the nozzle module 50 can be configured simply to cover the light outlet 23 and form a flow guide cavity 521, or it can be configured as a combination of the air guide 51 and the nozzle 52 in the following embodiment. Alternatively, the air guide tube 220 can be directly extended from the external air source into the accommodating cavity 11 and connected to the nozzle module 50, or in the following embodiment, an installation port 13 can be opened on the outer shell 10, an external air source can be connected through the installation port 13, and an air guide hose 55 can be provided in the accommodating cavity 11 to connect the installation port 13 and the nozzle module 50.

[0076] Optionally, the cross-section of the guide cavity 512 can be gradually narrowed along the air outlet direction to converge the airflow and concentrate the airflow to be blown out from the outlet 522, which helps to increase the blowing force.

[0077] In addition, the laser 100 is also equipped with a lifting module 30, which can be a screw drive structure, a cylinder or hydraulic cylinder push structure, a linear motor structure, a worm gear structure or a gear rack structure, etc., so that the lifting module 30 is connected to the laser module 20 for transmission, and thus the laser module 20 and the air nozzle module 50 can be driven to rise and fall through the lifting module 30.

[0078] Therefore, it is understood that in the technical solution of this application, the laser module 20 in the laser 100 can be raised and lowered in the housing 10 by the lifting module 30 to adjust the height position of the laser focus; and, a nozzle module 50 is provided over the light outlet 23, the nozzle module 50 has a flow guide cavity 521 and an outlet 522 communicating with the flow guide cavity 521, the outlet 522 of the flow guide cavity 521 is arranged opposite to the light outlet 23 of the laser module 20, so that the laser can be emitted through the outlet 522. When processing using the laser 100 of this application, the air nozzle module 50 can be connected to the air supply structure 300. The air supply structure 300 supplies airflow to the air nozzle module 50, and the airflow is blown outward through the guide cavity 521 and the outlet 522. This blows away dust and smoke outside the outlet 522, and the continuous airflow also prevents dust and other impurities from entering the guide cavity 521 and entering the light output port 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting laser emission. Furthermore, since the air nozzle module 50 is fixed on the laser module 20, it can rise and fall together with the laser module 20, so that the air nozzle module 50 can always form an airflow at the front end of the air nozzle 52 of the laser module 20. It can also direct the airflow to the processing position, preventing dust from adhering to the processing position, playing a good dustproof role and ensuring the processing effect.

[0079] By setting an air guide channel 513 in the air nozzle module 50, it is not necessary to set an air pipe extending to the light output position and connecting it to the flow guide cavity 521. This can hide the air path, and there will be no air pipe under the laser module 20. This can avoid the problem of air pipes easily interfering with other devices during laser processing, and make the laser 100 look neat and uniform.

[0080] In addition, in the laser 100 of this utility model, only the laser module 20 and the air nozzle module 50 are raised and lowered to adjust the height position of the laser focus and the blowing position. Therefore, it is not necessary to raise and lower the entire laser 100 in the laser device 1, making the process of adjusting the height of the laser module 20 and the air nozzle module 50 more convenient.

[0081] Please refer to Figures 9 to 11In some embodiments of this application, the air nozzle module 50 includes an air guide 51, an air nozzle 52, and an air pipe connector 56. The air guide 51 is located below the laser module 20. The air guide 51 has an air guide channel 513 inside. The end of the air guide channel 513 away from the light outlet 23 has an inlet for connecting to an air source. The end of the air guide 51 near the light outlet 23 has a first chamber 514 that extends through both ends along the center line of the light outlet 23. The first chamber 514 is connected to the air guide channel 513. The air nozzle 52 is covered on the side of the air guide 51 facing away from the laser module 20. The air nozzle 52 has a second chamber 523 and an outlet 522. The second chamber 523 is connected to the first chamber 514 to form a flow guide cavity 521.

[0082] In this embodiment, the air nozzle module 50 includes an air guide 51, an air nozzle 52, and an air pipe connector 56. Both the air nozzle 52 and the air guide 51 are covered below the laser module 20. The air guide 51 includes a connected air guide portion 511 and a connecting portion 512. An air guide channel 513 is formed in the air guide portion 511. The connecting portion 512 is covered at the light outlet 23 and has a first chamber 514. The air guide channel 513 and the first chamber 514 are interconnected through an air guide port. The air nozzle 52 is covered on the side of the air guide 51 facing away from the laser module 20 and is connected to the connecting portion 512 of the air guide 51. The air nozzle 52 and the air guide 51 can be integrally set to improve the overall structural stability of the air nozzle module 50. Alternatively, the air nozzle 52 and the air guide 51 can be detachably connected. The air nozzle 52 is provided with a second chamber 523, which is connected to the first chamber 514 to jointly form a guide cavity 521. The air guide 51 is provided with an inlet located away from the guide cavity 521. The inlet is connected to an air pipe connector to facilitate the connection of an air pipe. This eliminates the need for the air pipe 220 connected to the air source to extend directly to the position near the light output port 23 of the laser module 20, thereby avoiding the air pipe 220 from blocking the light output or causing other effects on the laser processing process.

[0083] Please refer to Figure 12 In some embodiments of this application, the air nozzle 52 and the air guide 51 are detachably connected. The detachable connection between the air nozzle 52 and the air guide 51 can be at least one of the following: threaded connection, bolt connection, magnetic connection, or snap-fit ​​connection. This configuration allows for direct cleaning and maintenance of the first chamber 514 and the second chamber 523 by removing the air nozzle 52. Furthermore, in some embodiments, the light-emitting structure includes optical elements such as a focusing lens; the focusing lens can also be maintained or replaced by removing the air nozzle 52, improving ease of use.

[0084] Please refer to Figure 12 In some embodiments of this application, the air nozzle 52 is magnetically connected to the air guide 51.

[0085] In this embodiment, the air nozzle 52 and the air guide 51 are detachably connected by magnetic attraction. This can be achieved by placing a magnet 53 on the air nozzle 52 and a magnet 53 or a magnetic guide 54 that can attract the magnet 53 on the air guide 51; alternatively, a magnet 53 can be placed on the air guide 51 and a magnetic guide 54 on the air nozzle 52. With this configuration, when installing the air nozzle 52, it only needs to be brought close to the air guide 51 to be attracted to it; when removing the air nozzle 52, it can be directly removed with force, making the installation and removal of the air nozzle 52 relatively simple.

[0086] Please refer to Figure 12 In some embodiments of this application, one of the air guide 51 and the air nozzle 52 is provided with a magnet 53, and the other of the air guide 51 and the air nozzle 52 is provided with a magnetic guide 54. The magnetic guide 54 is arranged around the circumference of the flow guide cavity 521 and magnetically engages with the magnet 53.

[0087] In this embodiment, a magnetic guide 54 can be fixed on the surface of the air guide 51 facing the air nozzle 52, and a magnet 53 can be provided on the surface of the air guide 51 facing the air nozzle 52. Alternatively, a magnet 53 can be provided on the surface of the air guide 51 facing the air nozzle 52, and a magnetic guide 54 can be provided on the surface of the air guide 51 facing the air nozzle 52. The magnetic guide 54 can be a metal part that can be attracted by the magnet 53, such as being made of iron, cobalt, nickel, etc. The magnetic guide 54 can also be a magnet, with the magnet on the air guide 51 and the magnet on the air nozzle 52 having opposite magnetic poles to generate a magnetic attraction force between them. Furthermore, the magnetic guide 54 is arranged around the circumference of the flow guide cavity 521, and the magnet 53 can also be arranged around the circumference of the flow guide cavity 521, or at least two magnets 53 can be spaced apart along the circumference of the flow guide cavity 521, so that the air nozzle 52 can be detachably connected to the air guide component 51 through the magnetic attraction between the magnet 53 and the magnetic guide 54, and the air nozzle 52 is subjected to uniform force along the circumference of the flow guide cavity 521, thereby improving installation stability.

[0088] Please refer to Figure 11 and Figure 12 In some embodiments of this application, a limiting step 515 is provided on the side of the air guide 51 away from the laser module 20, the first chamber 514 is provided on the limiting step 515, and part of the air nozzle 52 is embedded in the limiting step 515.

[0089] In this embodiment, a limiting step 515 is recessed on the surface of the air guide 51 facing the air nozzle 52, and at least part of the air nozzle 52 is embedded in the limiting step 515. This can not only play a positioning role when installing the air nozzle 52, improving the ease of installation, but also prevent the air nozzle 52 from shifting on the surface of the air guide 51, ensuring that the light outlet 23 of the laser module 20 is opposite to the outlet 522 of the air nozzle 52, thereby ensuring that the laser can be emitted from the outlet 522 of the air nozzle 52.

[0090] Please refer to Figure 12 In some embodiments of this application, the air nozzle module 50 further includes a sealing gasket 57, which is sandwiched between the air nozzle 52 and the air guide 51 and surrounds the flow guide cavity 521.

[0091] In this embodiment, a sealing gasket 57 is provided between the air guide 51 and the air nozzle 52, and the sealing gasket 57 is arranged around the flow guide cavity 521; and the sealing gasket 57 is generally elastic and can be elastically deformed by the compression of the air guide 51 and the air nozzle 52 to tightly adhere to the air guide 51 and the air nozzle 52, improve airtightness, and prevent gas from leaking out from between the air nozzle 52 and the air guide 51.

[0092] In one embodiment of this application, a slot 516 is provided on the surface of the air guide 51 facing the laser module 20. This design reduces the weight of the air guide 51, making the lifting and lowering process of the laser module 20 easier.

[0093] Please refer to Figure 9 and Figure 10 In some embodiments of this application, the outer casing 10 is provided with an installation port 13, and the laser 100 also includes an air inlet connector 90 and an air guide hose 55. The air inlet connector 90 is located in the accommodating cavity 11 and is located in the installation port 13. The air guide hose 55 bends and extends in the accommodating cavity 11. One end of the air guide hose 55 is connected to the air inlet connector 90, and the other end of the air guide hose 55 is connected to the air pipe connector 56. The air guide hose 55 is adaptively deformed as the laser module 20 is raised and lowered.

[0094] In this embodiment, the laser module 20 and other components in the laser 100 are height-adjustable while the outer casing 10 and some structures remain fixed, making the process of adjusting the laser focus height easier. In this embodiment, an installation port 13 is provided on the outer casing 10, and an air inlet connector 90 is installed at the installation port 13. A gas guide hose 55 is provided in the accommodating cavity 11. The gas guide hose 55 can be bent and deformed as needed, and the gas guide hose 55 can be made of materials such as plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), and PP (polypropylene). One end of the air guide hose 55 is connected to the air inlet connector 90, and the other end of the air guide hose 55 is connected to the air pipe connector 56, so that the length of the air guide hose 55 is greater than the straight-line distance between the air nozzle module 50 and the air inlet connector 90, and the air guide hose 55 has a partial bend; with this setting, when the air nozzle module 50 rises and falls with the laser module 20, the air guide hose 55 can undergo adaptive deformation to move with the air nozzle module 50, maintain the connection between the air nozzle module 50 and the air nozzle module 50, so that the airflow is more stable and the blowing dust removal effect is guaranteed.

[0095] In this embodiment, the external air source is connected to the air inlet connector 90 fixed to the outer casing 10, and the outer casing 10 does not move up or down in the laser device 1. This avoids the connection structure between the external air source and the laser 100 being stretched when the height of the laser module 20 and the air nozzle module 50 is adjusted. It also eliminates the need to reserve a long connection structure to accommodate the lifting and lowering of the laser module 20, thus avoiding interference and improving the stability and safety of the lifting and lowering process of the laser module 20.

[0096] Please refer to Figure 9 and Figure 12 In some embodiments of this application, the air guide hose 55 is located on the side of the laser module 20, and the air pipe connector 56 includes a first connector 561 and a second connector 562 arranged at an angle. The first connector 561 is inserted into the inlet, and the second connector 562 is arranged facing upwards and inserted into one end of the air guide hose 55.

[0097] In this embodiment, the air pipe connector 56 includes a first connector 561 inserted into the inlet of the air guide 51, and a second connector 562 communicating with the first connector 561. The second connector 562 extends upward along the lifting direction of the laser module 20, so that when the air guide hose 55 is connected to the air pipe connector 56, the air guide hose 55 extends along the height direction, so that the bending deformation direction of the air guide hose 55 is the same as the lifting direction of the laser module 20 and the air nozzle module 50, thereby reducing the interference of the air guide hose 55 on the lifting of the laser module 20 and making the airflow more stable.

[0098] Please refer to Figures 2 to 7 In some embodiments of this application, the laser 100 further includes a heat dissipation module 40, which is disposed in the accommodating cavity 11.

[0099] In this embodiment, the heat dissipation module 40 can be equipped with a cooling fan 41 to drive airflow to dissipate heat from the laser 100; it can also be equipped with a heat dissipation fin structure to increase the heat dissipation area; or it can be equipped with a water-cooled heat dissipation module 40. All of these can be used to improve the heat dissipation efficiency of the laser 100, prevent heat accumulation in the laser 100, and ensure the stable performance of the laser 100. In addition, the heat dissipation module 40 can be raised and lowered together with the laser module 20, or the heat dissipation module 40 can be fixed to the outer shell 10, or in the following embodiment, the cooling fan 41 can be fixed to the outer shell 10, and the heat dissipation fins can be fixed on the laser module 20 to improve the heat dissipation efficiency of the laser module 20.

[0100] Please refer to Figure 9In some embodiments of this application, the laser module 20 is provided with a mirror tube 22 inserted into the flow guide cavity 521. The end of the mirror tube 22 facing the outlet 522 forms a light outlet 23, so that the air inlet of the flow guide cavity 521 is arranged opposite to the side wall of the mirror tube 22. With this arrangement, the outer side wall of the mirror tube 22 can be used to guide the airflow, so that the airflow flows along the side wall of the mirror tube 22 to the side of the mirror tube 22 opposite to the heat dissipation port 12, and the airflow flows downward and blows out from the outlet 522.

[0101] In one embodiment of this application, the light outlet 23 is provided with a window mirror. This arrangement can prevent dust, smoke, and airflow from the nozzle module 50 from entering the laser module 20 through the light outlet 23.

[0102] In some embodiments, the laser module 20 may include a laser generator 21 and a lens barrel 22. The laser generator 21 is used to generate laser light, and the lens barrel 22 is located at the light-emitting position of the laser generator 21. The lens barrel 22 may only contain a window lens, while the focusing lens is located in the laser generator 21. Alternatively, the lens barrel 22 may include a focusing lens group 222 and a window lens group 221 connected to each other, that is, both the focusing lens and the window lens are located in the lens barrel 22, thereby facilitating the replacement of focusing lenses with different focal lengths to adapt to different processing requirements. In addition, when the lens barrel 22 includes a focusing lens group 222 and a window lens group 221, the window lens group 221 and the focusing lens group 222 may be detachably connected, for example, by sleeve or threaded connection between the window lens group 221 and the focusing lens group 222.

[0103] Please refer to Figures 3 to 7 In some embodiments of this application, the top of the housing 10 is provided with a heat dissipation port 12 communicating with the accommodating cavity 11. The laser 100 also includes a heat dissipation module 40, which includes a heat dissipation fan 41. The heat dissipation fan 41 is disposed in the accommodating cavity 11 and located above the laser module 20. The air outlet of the heat dissipation fan 41 is arranged facing the laser module 20.

[0104] In this embodiment, the heat dissipation module 40 includes a cooling fan 41, which is disposed on the top of the laser module 20. A heat dissipation vent 12 is formed in the bottom wall of the accommodating cavity 11. With this arrangement, the cooling fan 41 can drive external airflow into the accommodating cavity 11 and flow downwards to dissipate heat from the structure in the accommodating cavity 11. Furthermore, the cooling fan 41 is fixedly connected to the outer casing 10, eliminating the need for the cooling fan 41 to rise and fall with the laser module 20, making the process of controlling the rise and fall of the laser module 20 more convenient.

[0105] Combined with reference Figure 6 and Figure 10In some embodiments of this application, a mounting plate 14 is provided in the accommodating cavity 11, the mounting plate 14 has a ventilation opening 141, a cooling fan 41 is provided on the upper surface of the mounting plate 14 and is positioned towards the ventilation opening 141, and the laser module 20 is provided below the mounting plate 14.

[0106] In this embodiment, a mounting plate 14 is provided in the accommodating cavity 11. The mounting plate 14 is fixedly connected to the outer shell 10, and a ventilation port 141 is opened on the mounting plate 14. The cooling fan 41 is fixed on the upper surface of the mounting plate 14, and the air outlet of the cooling fan 41 is set towards the ventilation port 141. This arrangement can prevent the cooling fan 41 from being suspended in the air, improve the stability of the cooling fan 41 fixed in the accommodating cavity 11, and prevent the setting of the mounting plate 14 from affecting the airflow driven by the cooling fan 41 to dissipate heat from structures such as the laser module 20.

[0107] Please refer to Figures 5 to 7 In some embodiments of this application, the heat dissipation module 40 includes a heat sink disposed on at least one side surface of the laser module 20. The heat sink is connected to the laser module 20, and a plurality of heat dissipation fins are disposed on the surface of the heat sink away from the laser module 20. The plurality of heat dissipation fins are arranged side by side.

[0108] In this embodiment, a heat sink can be provided on only one side of the laser module 20, or a heat sink can be provided on both sides of the laser module 20 facing away from each other. The heat sink has several heat dissipation fins arranged side by side. The heat sink can be made of a material with good thermal conductivity and heat dissipation performance, such as aluminum, aluminum alloy, copper or copper alloy. This allows the heat on the laser module 20 to be quickly transferred to the heat sink, and the several heat dissipation fins on the heat sink form a large heat dissipation area 421, so that the heat transferred to the heat sink can be quickly dissipated.

[0109] Please refer to Figures 5 to 7 In some embodiments of this application, the heat dissipation module 40 includes a cooling fan 41 disposed above the laser module 20, and a plurality of heat dissipation fins arranged horizontally. This arrangement ensures that the heat dissipation fins extend approximately along the flow direction of the airflow driven by the cooling fan 41, forming airflow paths between adjacent fins. This allows airflow to pass through these paths as it passes over the radiator, ensuring sufficient contact with each fin and carrying away heat, thus improving the radiator's heat dissipation efficiency. Furthermore, arranging the fins horizontally avoids direct impact on the surface of the fins, preventing obstruction and ensuring normal airflow.

[0110] In some embodiments, the lifting module 30 in the laser 100 can be connected to a heat sink, thereby driving the laser module 20 to rise and fall by driving the heat sink to rise and fall. For ease of explanation, in the following embodiments, the heat sink connected to the lifting module 30 is defined as the first heat sink 42, and the heat dissipation fins on the first heat sink 42 are defined as the first heat dissipation fins 423; when the heat dissipation module 40 includes two heat sinks disposed on two sides opposite to the laser module 20, the other heat sink not connected to the lifting module 30 is defined as the second heat sink 43, and the heat dissipation fins on the second heat sink 43 are defined as the second heat dissipation fins 431.

[0111] Please refer to Figure 7 In some embodiments of this application, the lifting module 30 is connected to the first heat sink 42 to drive the first heat sink 42 to lift the laser module 20.

[0112] In this embodiment, the first heat sink 42 is fixed to one side surface of the laser module 20, and the lifting module 30 is connected to the first heat sink 42 so that the laser module 20 can be lifted by driving the first heat sink 42 to lift. This arrangement can avoid the lifting module 30 being blocked by the first heat sink 42 when it is disassembled from the laser module 20, thus improving the convenience of disassembly and assembly.

[0113] Please refer to Figure 7 In some embodiments of this application, the side of the first heat sink 42 away from the laser module 20 includes a heat dissipation area 421 and a clearance area 422 arranged side by side in a horizontal direction. The heat dissipation area 421 is provided with a plurality of first heat dissipation fins 423. The lifting module 30 is opposite to the clearance area 422 and connected to the clearance area 422.

[0114] In this embodiment, a heat dissipation area 421 and a clearance area 422 are provided on the surface of the first heat dissipation area 421 opposite to the laser module 20. The lifting module 30 is placed in the area of ​​the clearance area 422, opposite to and connected to the clearance area 422. Several first heat dissipation fins 423 are arranged side by side in the heat dissipation area 421. This arrangement can reduce the overall thickness of the lifting module 30 and the first heat sink 42 when they cooperate, and reduce the volume of the laser 100. It should be noted that the clearance area 422 may not have any first heat dissipation fins 423 at all, or it may have some first heat dissipation fins 423 that conform to the outer surface of the lifting module 30, thereby improving space utilization and the heat dissipation efficiency of the first heat sink 42.

[0115] Combined with reference Figure 6 and Figure 10 In some embodiments of this application, the laser 100 further includes an optical axis 15, which is disposed in the accommodating cavity 11 and extends along the lifting direction of the laser module 20. The first heat sink 42 is detachably mounted on the optical axis 15.

[0116] In this embodiment, an optical axis 15 extending along the height direction of the laser 100 is provided in the accommodating cavity 11, and the first heat sink 42 is sleeved on the optical axis 15. The optical axis 15 guides and limits the lifting and lowering of the first heat sink 42 and the laser module 20, improving the stability of the lifting and lowering process. Alternatively, only one optical axis 15 can be provided, or at least two optical axes 15 can be provided side-by-side to balance the forces and create multiple limiting points, further improving the stability of the lifting and lowering process of the first heat sink 42 and the laser module 20.

[0117] Combined with reference Figure 6 and Figure 10 In some embodiments of this application, the first heat sink 42 is provided with a sliding hole 424 extending in the lifting direction, and a linear bearing 425 is provided in the sliding hole 424, through which the optical axis 15 passes.

[0118] In this embodiment, a sliding hole 424 extending along the height direction of the laser 100 is provided on the first heat sink 42, and a linear bearing 425 is installed in the sliding hole 424 so that the linear bearing 425 cooperates with the optical axis 15, thereby reducing the sliding friction between the first heat sink 42 and the optical axis 15 and improving the smoothness and stability of the lifting process of the first heat sink 42 and the laser module 20.

[0119] Please refer to Figure 7 , Figure 13 as well as Figure 14 In some embodiments of this application, the lifting module 30 of the laser 100 is disposed in the accommodating cavity 11. The lifting module 30 includes a driving member 31 connected to the outer shell 10 and a lifting rod 32 connected to the laser module 20. The lifting rod 32 extends along the lifting direction of the laser module 20, and the driving member 31 is used to drive the lifting rod 32 to rise and fall.

[0120] In this embodiment, the lifting module 30 includes a drive component 31 and a lifting rod 32. The drive component 31 and the lifting rod 32 are connected in a transmission manner. The drive component 31 and the lifting rod 32 can be a pump body and a piston rod in a cylinder or hydraulic cylinder, respectively. The drive component 31 and the lifting rod 32 can also form a motor lead screw assembly; or a motor and a rack or worm gear, connected by a gear or worm transmission. All of these can form a drive structure in which the lifting rod 32 is driven to rise and fall by the drive component 31. When the lifting module 30 is applied to the laser 100, the drive component 31 can be connected to the housing 10 of the laser 100, and the lifting rod 32 can be connected to the laser module 20 of the laser 100, so that the drive component 31 can drive the lifting rod 32 to move the laser module 20 up and down.

[0121] Please refer to Figure 13 and Figure 14In some embodiments of this application, the lifting module 30 further includes a lower dust cover 33, which is sleeved on the portion of the lifting rod 32 located below the drive member 31. The lower dust cover 33 has a first end and a second end located below the first end. The first end is connected to the drive member 31, and the second end is connected to the bottom end of the lifting rod 32. The lower dust cover 33 can extend and retract as the lifting rod 32 rises and falls.

[0122] In this embodiment, a lower dust cover 33 is fitted on the outside of the lifting rod 32 extending from the driving member 31. The lower dust cover 33 is telescopic and can be made of elastic material, or in the following embodiment, the lower dust cover 33 is made of corrugated material, so that the lower dust cover 33 can contract and expand with the lifting rod 32. When the lifting module 30 is applied to the laser 100, the lower dust cover 33 is fitted onto the portion of the lifting rod 32 located below the drive member 31. For ease of explanation, the two ends of the lower dust cover 33 are a first end and a second end, with the first end located above the second end. The first end of the lower dust cover 33 is connected to the drive member 31, and the second end is connected to the bottom end of the lifting rod 32. A sealed dustproof space is formed in the lower dust cover 33, and the opening at the lower end of the drive member 31 through which the lifting rod 32 passes is covered. This prevents dust and oil from contaminating the lifting rod 32 and also prevents dust and oil from entering the drive member 31 through the opening at the lower end of the drive member 31. Thus, dust and oil are prevented from clogging between the drive member 31 and the lifting rod 32, ensuring that the drive member 31 will not be blocked by impurities when driving the lifting rod 32, thereby ensuring smooth and stable operation of the lifting module 30.

[0123] Please refer to Figure 13 In some embodiments of this application, at least part of the lower dust cover 33 is corrugated.

[0124] In this embodiment, at least a portion of the lower dust cover 33 is configured as a corrugated structure composed of several sequentially connected corrugated segments. Each corrugated segment can be folded over to shorten the length of the lower dust cover 33, and the corrugated segments of the lower dust cover 33 can also be extended relative to each other to lengthen the lower dust cover 33. Alternatively, the entire lower dust cover 33 can be configured as a retractable corrugated structure, which maximizes the range of length variation and broadens its applicability. Or, only a portion of the lower dust cover 33 can be configured as a retractable corrugated structure. This allows for setting the minimum contracted length of the lower dust cover 33 by adjusting the length of the non-corrugated segments, preventing excessive contraction and puncture by the lifting rod 32, thus avoiding compromised dustproof performance.

[0125] Please refer to Figure 13 and Figure 14In some embodiments of this application, the lifting module 30 further includes a fixed base 34, the fixed base 34 is provided with a through hole 341, the fixed base 34 is connected to the outer shell 10, the driving member 31 is provided on the fixed base 34, and the lifting rod 32 extends downward through the through hole 341 and can move up and down relative to the through hole 341.

[0126] In this embodiment, the lifting module 30 also includes a fixing base 34, which is used to fix the lifting module 30 to the installation position of the equipment. For example, when the lifting module 30 is applied to the laser 100, the fixing base 34 can be fixedly connected to the outer shell 10 of the laser 100. In the lifting module 30, the driving member 31 is fixed on the fixing base 34, and the lifting rod 32 passes through the through hole 341 on the fixing base 34. The lower dust cover 33 can extend and retract between the fixing base 34 and the bottom end of the lifting rod 32. The lower dust cover 33 can be connected to the fixing base 34, or one end of the lower dust cover 33 can pass through the through hole 341 and be connected to the driving member 31. The setting of the fixing base 34 can improve the installation stability of the lifting module 30 and facilitate the fixing of the lifting module 30 in the installation position, without the need to set up a special support structure in the equipment for fixing the lifting module 30.

[0127] Combined with reference Figure 13 and Figure 14 In some embodiments of this application, the first end of the lower dust cover 33 is provided with a clamping part 331, the lower dust cover 33 passes through the through hole 341, and the clamping part 331 is clamped between the fixed base 34 and the driving member 31.

[0128] In this embodiment, a clamping part 331 is provided at the first end of the lower dust cover 33 near the drive member 31, and the lower dust cover 33 passes through the through hole 341 of the fixing base 34, so that the clamping part 331 is located between the fixing base 34 and the drive member 31, and is clamped and fixed by the fixing base 34 and the drive member 31, thereby improving the connection strength and positional stability of the end of the lower dust cover 33 near the drive member 31, and preventing the end of the lower dust cover 33 near the drive member 31 from loosening and falling off. The clamping part 331 may be provided only at one position in the circumferential direction of the lower dust cover 33. In some embodiments, the clamping part 331 may be a sheet-like structure arranged circumferentially, or it may be two or more connecting ears distributed circumferentially.

[0129] Please refer to Figure 7 In some embodiments of this application, the lifting module 30 further includes a protective pad 35, which is located on the side of the lower dust cover 33 facing away from the drive member and is connected to the lifting rod 32. The cross-sectional dimension of the protective pad 35 is not smaller than the cross-sectional dimension of the lower dust cover 33.

[0130] In this embodiment, the lifting module 30 is further provided with a protective pad 35. The protective pad 35 can be made of materials such as vacuum board, glass wool, expanded perlite, fiberglass felt, and polystyrene foam board, among others, giving it at least one of the functions of fire resistance and heat insulation. The protective pad 35 is installed at the bottom end of the lifting rod 32, and the lower dust cover 33 is located above the protective pad 35, between the second end of the lower dust cover 33 and the bottom end of the lifting rod 32; furthermore, the cross-sectional dimension of the protective pad 35 is not smaller than the cross-sectional dimension of the lower dust cover 33. With this configuration, when the lifting module 30 is used in laser equipment, the lower dust cover 33 can be isolated from the processing position and the laser by the protective pad 35, preventing heat generated during laser or processing from being transferred to the lower dust cover 33, thereby preventing the lower dust cover 33 from catching fire or causing other forms of damage, and improving safety. In addition, the protective pad 35 can also play a certain role in blocking dust and oil stains, improving the dustproof performance of the lifting module 30.

[0131] In some embodiments, the cross-sectional profile of the position on the lifting rod 32 for fitting the protective pad 35 can be non-circular, and the shape of the socket on the protective pad 35 can be adapted to the cross-sectional shape of the lifting rod 32, thereby preventing the protective pad 35 from rotating on the lifting rod 32.

[0132] Please refer to Figure 13 and Figure 14 In some embodiments of this application, the driving component 31 is a motor, the lifting rod 32 is a lead screw, the motor has a mounting hole 311 that extends through the length of the lead screw, the lead screw is inserted into the mounting hole 311 and can extend outward along the openings at both ends of the mounting hole 311.

[0133] In this embodiment, the lifting module 30 is a through-type lead screw motor module, wherein the lifting rod 32 is a lead screw, the driving component 31 is a motor, and the motor has a mounting hole 311 that runs through the length of the lead screw. The lead screw is inserted into the mounting hole 311 and can extend above and below the driving component 31 from both ends of the mounting hole 311. The rotor in the motor is threadedly connected to the lead screw, so that when the rotor rotates, it can drive the lead screw to move along the length of the lead screw. By using a through-type lead screw motor module as the lifting module 30, the lifting module 30 occupies less space and can make full use of the space at both ends of the motor for the movement of the lead screw, thereby reducing the size of the devices and equipment using this lifting module 30.

[0134] Please refer to Figure 7 In some embodiments of this application, the lifting module 30 further includes an upper dust cover 36, which covers the opening at one end of the mounting hole 311 away from the lower dust cover 33. The upper dust cover 36 has a movable space with a lower opening inside, and the part of the lead screw extending above the motor is housed in the movable space and can move relative to the movable space.

[0135] In the aforementioned embodiments, a through-type lead screw motor module is used as the lifting module 30, in which case the lead screw can protrude from the upper end of the motor. In this embodiment, an upper dust cover 36 is provided at one end of the motor away from the lower dust cover 33, and the upper dust cover 36 covers the upper opening of the mounting hole 311; and an active space communicating with the mounting hole 311 is formed in the upper dust cover 36. At this time, the upper dust cover 36 can cover the lead screw and the mounting hole 311, preventing dust and oil stains and other impurities from adhering to the part of the lead screw protruding from the top of the motor, and preventing dust and oil stains and other impurities from entering the motor from the upper opening of the mounting hole 311. This can prevent dust and oil stains and other impurities from blocking between the drive component 31 and the lifting rod 32, ensuring that the drive component 31 will not be blocked by impurities when driving the lifting rod 32, and ensuring that the lifting module 30 operates smoothly and stably.

[0136] Please refer to Figure 13 and Figure 14 In some embodiments of this application, the upper dust cover 36 includes a dust cover 361 and a support 362. The support 362 covers the motor, and the dust cover 361 is connected to the end of the support 362 away from the motor and extends along the axial direction of the lifting rod 32. The radial dimension of the support 362 is larger than the radial dimension of the dust cover 361, and the dust cover 361 has an active space inside.

[0137] In this embodiment, the upper dust cover 36 includes a dust cover part 361 and a support part 362. The support part 362 abuts against the motor. The dust cover part 361 is connected to the end of the support part 362 away from the motor and has a generally cylindrical structure, forming an open space on the lower side. The radial dimension of the support part 362 is larger than the radial dimension of the dust cover part 361. By increasing the contact area with the motor using the support part 362, the connection strength between the upper dust cover 36 and the motor can be improved.

[0138] Please refer to Figure 6 In some embodiments of this application, the laser 100 further includes a position detection module 60, which is disposed in the accommodating cavity 11 and is used to detect the position of the laser module 20.

[0139] In this embodiment, the laser module 20 is height-adjustable relative to the outer casing 10, allowing adjustment of the height of the laser module 20's output port 23 according to different processing positions, thereby improving processing accuracy and effect. Furthermore, before each laser processing operation, the laser module 20 needs to be raised and reset to a preset origin position, facilitating control of the lifting module 30 to lower the laser module 20 to the desired position. In this embodiment, a position detection module 60 is provided in the laser 100 to detect the position of the laser module 20. The position detection module 60 can detect the height of the laser module 20, or it can detect whether the laser module 20 has been raised and reset to the preset origin position, thereby improving the accuracy of height adjustment of the laser module 20. The position detection module 60 can be at least one of a proximity switch, photoelectric detection switch, grating ruler detection module, Hall sensor, etc., and is not limited here.

[0140] Combined with reference Figure 6 , Figure 15 as well as Figure 16 In some embodiments of this application, the position detection module 60 is used to detect whether the laser module 20 has returned to a preset origin position. The position detection module 60 includes a mounting shell 61, a sensing module 63, and a first reset member 65. The mounting shell 61 has a mounting cavity 613 and a first through hole 614 communicating with the mounting cavity 613. The sensing module 63 includes a movable member 631, a first trigger member 633, and a first sensing member 635. The movable member 631 is movably disposed in the first through hole 614 and has a first position and a second position. The first trigger 633 and the first sensor 635 are both located in the mounting cavity 613. One of the first trigger 633 and the first sensor 635 is disposed on the movable member 631, and the other of the first trigger 633 and the first sensor 635 is connected to the mounting shell 61. When the movable member 631 is in the first position, the first trigger 633 triggers the first sensor 635. The first reset member 65 is disposed in the mounting cavity 613 and acts between the mounting shell 61 and the movable member 631 so that the movable member 631 tends to remain in the second position.

[0141] Specifically, the mounting shell 61 serves as the mounting base for the position detection module 60, and a mounting cavity 613 is formed within it. The outer contour of the mounting shell 61 can be a cuboid, cube, cylinder, prism, or other regular or irregular structure. The mounting cavity 613 formed within it can conform to the outer contour or be set into other shapes. The mounting shell 61 can include an upper shell 611 and a lower shell 612 that cover each other, or it can be set as a side-opening door structure so that the mounting cavity 613 can be opened to disassemble and assemble the internal structure. The movable component 631 of the sensing module 63 passes through the first through hole 614 opened on the mounting shell 61 and extends outward from the mounting cavity 613. The movable component 631 can slide relative to the mounting shell 61 along the direction of the central axis of the first through hole 614 and has a first position and a second position. In addition, a first reset component 65 is provided between the movable component 631 and the mounting shell 61. The first reset component 65 can be an elastic component such as a spring, gas spring, or elastic air bag. The elastic component can be provided on the top wall side opposite to the first through hole 614 and apply an elastic thrust to the movable component 631 toward the first through hole 614, so that the movable component 631 has a tendency to move from the first position to the second position and remain in the second position. Alternatively, the elastic component can be provided on the cavity wall where the first through hole 614 is opened and connected to the movable component 631 to apply an elastic pull to the movable component 631, which can also make the movable component 631 have a tendency to move from the first position to the second position and remain in the second position. The first reset member 65 can also be a magnetic structure. This magnetic structure may include a first magnetic element and a second magnetic element respectively disposed on the movable member 631 and the mounting shell 61. A magnetic attraction force can exist between the first and second magnetic elements, causing the movable member 631 to tend to move from the first position to the second position and remain there. Alternatively, a magnetic repulsion force can exist between the first and second magnetic elements, which can be used to push the movable member 631, causing it to tend to move from the first position to the second position and remain there. When the movable member 631 is moved into the mounting cavity 613 by an external force, it overcomes the force applied by the first reset member 65. When the external force on the movable member 631 is removed, the force applied by the first reset member 65 to the movable member 631 will cause the movable member 631 to move to the second position.

[0142] The sensing module 63 also includes a first trigger 633 and a first sensor 635 disposed in the mounting cavity 613. The first sensor 635 can be connected to the mounting shell 61, and the first trigger 633 can be disposed on the movable member 631, so that the first trigger 633 moves relative to the first sensor 635 with the movable member 631. When the movable member 631 moves from the second position to the first position, the first trigger 633 will trigger the first sensor 635 to emit a sensing signal. In this embodiment, the first trigger 633 can also be connected to the mounting shell 61, and the first sensor 635 can be disposed on the movable member 631 to move relative to the first trigger 633 with the movable member 631. When the movable member 631 moves from the second position to the first position, the first trigger 633 can also trigger the first sensor 635 to emit a sensing signal.

[0143] The first sensing element 635 can be configured as a Hall sensor, photoelectric switch, proximity switch, grating reading head, etc. For example, if the first sensing element 635 is a Hall sensor and the first trigger element 633 is a magnet 53, when the first trigger element 633 moves between a first position and a second position with the movable element 631, the magnetic field strength around the Hall sensor changes, for example, from weak to strong or from strong to weak. Using the magnetic field strength detected by the Hall sensor when the first trigger element 633 is in the first position as the trigger condition, the Hall sensor can emit a sensing signal when the first trigger element 633 reaches the first position. If a proximity switch is used as the first sensing element 635, the first trigger element 633 can touch the sensing surface of the proximity switch when the movable element 631 is in the first position, thereby causing the proximity switch to emit a sensing signal. If a grating reading head is used as the first sensing element 635, and the first trigger element 633 is a scale grating extending along the movement direction of the movable element 631, when the movable element 631 moves from the second position to the first position, the scale grating and the grating reading head move relative to each other. The grating reading head can read the displacement relative to the scale grating and convert the displacement into an electrical signal. This signal is then processed by a signal processing circuit to obtain displacement data, thereby generating a sensing signal when the first trigger element 633 moves the corresponding distance from the second position to the first position. The usage methods when other structures are used as the sensing module 63 are not described in detail here.

[0144] In this embodiment, the movable component 631 is positioned relative to at least a portion of the laser module 20 in the height direction. When the laser module 20 rises relative to the mounting housing 61 to reset to its origin, the laser module 20 can push the first trigger component 633 upward. When the laser module 20 moves to the preset origin position, the movable component 631 moves to the first position, causing the first trigger component 633 to trigger the first sensor component 635 to emit a sensing signal indicating that the laser module 20 has completed its reset. The sensing signal is then fed back to the controller to stop the laser module 20 from moving. This configuration allows for relatively precise control of the laser module 20's reset to its origin. Since both the first sensor component 635 and the first trigger component 633 of the position sensing module 63 are located within the mounting housing 61, external dust and oil will not affect this part of the structure, ensuring the stable performance of the position detection module 60. This ensures that the position detection module 60 can accurately detect the state information of the laser module 20 when it reaches the reset position and provide feedback.

[0145] Since both the first trigger element 633 and the first sensing element 635 are located in the mounting cavity 613, they will not be contaminated or interfered with by external dust, oil, or other debris. This reduces the risk of problems such as poor detection or false triggering, and ensures the stable performance and detection accuracy of the position detection module 60.

[0146] Please refer to Figure 15 and Figure 16 In some embodiments of this application, the first reset member 65 is an elastic member, which is disposed between the movable member 631 and the cavity wall of the mounting cavity 613 along the movement direction of the first trigger member 633.

[0147] In this embodiment, the first reset member 65 can be an elastic member such as a spring, gas spring, or elastic airbag. The elastic member can be disposed on the top wall side opposite to the first through hole 614 and located between the top wall and the movable member 631, so as to apply an elastic thrust toward the first through hole 614 side to the movable member 631, so that the movable member 631 has a tendency to move from the first position to the second position and remain in the second position.

[0148] The elastic element can also be disposed on the cavity wall with the first through hole 614 and connected to the movable element 631 to apply an elastic tension to the movable element 631, which can also make the movable element 631 have the tendency to move from the first position to the second position and remain in the second position.

[0149] Specifically, when the movable part 631 is not subjected to external force, it is in the second position under the elastic force of the elastic element; during the process of the movable part 631 moving into the mounting cavity 613 to the first position under the force of external force, the elastic element undergoes elastic deformation and generates an elastic force opposite to the direction of the external force. When the external force on the movable part 631 is removed, the elastic element will restore its shape and move the movable part 631 to the second position.

[0150] Please refer to Figure 16 and Figure 17 In some embodiments of this application, the mounting cavity 613 has a top wall opposite to the first through hole 614, and a limiting post 6315 is provided at one end of the movable member 631 facing the top wall, and an elastic member is sleeved on the limiting post 6315.

[0151] In this embodiment, the mounting cavity 613 has a top wall that is opposite to the first through hole 614, and an elastic member is disposed between the top wall of the mounting cavity 613 and the movable member 631. At this time, the elastic member applies an elastic thrust toward the movable member 631 toward the side of the first through hole 614.

[0152] Meanwhile, a limiting post 6315 protrudes from the end of the movable part 631 facing the top wall. The limiting post 6315 can be integrally formed with the movable part 631, or it can be detachably or non-detachably connected to the movable part 631. Furthermore, an elastic element is fitted onto the limiting post 6315. For example, a spring can be fitted onto the limiting post 6315, or the elastic airbag can be configured as an annular inflatable ring fitted onto the limiting post 6315; or the piston rod of the gas spring can be configured as a hollow rod fitted onto the limiting post 6315. This configuration improves the positional stability of the elastic element, prevents it from shifting, ensures that the elastic element can stably act on the movable part 631, and guarantees the overall structural and performance stability.

[0153] Please refer to Figure 16 and Figure 17 In some embodiments of this application, a limiting hole 6317 is provided at one end of the movable member 631 facing the top wall, and a portion of the limiting post 6315 is inserted into the limiting hole 6317; or, the limiting post 6315 is integrally formed with the movable member 631.

[0154] In this embodiment, the limiting post 6315 can be integrally formed with the movable member 631. This configuration provides a high connection strength between the limiting post 6315 and the movable member 631, resulting in a more stable relative position and improved overall structural stability. In some embodiments, the limiting post 6315 can also be detachably connected to the movable member 631. When this is done, a limiting hole 6317 can be formed at the end of the movable member 631 facing away from the first through hole 614. Part of the limiting post 6315 can be inserted into the limiting hole 6317, further enhancing the connection strength between the limiting post 6315 and the movable member 631. This prevents the limiting post 6315 from easily detaching from the movable member 631, ensuring the elastic element stably acts on the movable member 631 and improving overall structural stability. Alternatively, one end of the elastic member facing the movable member 631 can be inserted into the limiting hole 6317 to further limit the elastic member. Of course, a countersunk hole 6319 can be opened on the end face of the movable member 631, and a limiting hole 6317 can be opened on the bottom wall of the countersunk hole 6319, so that one end of the elastic member is inserted into the countersunk hole 6319 and abuts against the bottom wall of the countersunk hole 6319, and one end of the limiting post 6315 passes through the countersunk hole 6319 and is inserted into the limiting hole 6317.

[0155] In addition, in some embodiments, the limiting post 6315 can be inserted through the cavity wall of the mounting cavity 613 opposite to the first through hole 614, thereby providing auxiliary positioning and limiting function for the movable part 631 and preventing the movable part 631 from deflecting. In this case, by increasing the connection strength between the limiting post 6315 and the movable part 631 and ensuring the stability of the relative position between the limiting post 6315 and the movable part 631, the problem of interference between the limiting post 6315 and the movable part 631 caused by the deflection of the limiting post 6315 can be avoided.

[0156] Please refer to Figure 16 In some embodiments of this application, the mounting shell 61 has a second through hole 615 that is opposite to the first through hole 614, and one end of the movable member 631 located in the mounting cavity 613 is inserted into the second through hole 615.

[0157] In this embodiment, a second through hole 615 can be provided in the mounting shell 61, which is opposite to the first through hole 614. For example, the second through hole 615 can be provided on the top wall opposite to the first through hole 614, or a limiting plate can be provided in the mounting cavity 613, and the second through hole 615 can be provided in the limiting plate. At the same time, one end of the movable member 631 located in the mounting cavity 613 is inserted into the second through hole 615. With this configuration, the first through hole 614 and the second through hole 615, which are opposite to each other, provide positioning and limiting functions for the movable member 631 at different positions in the length direction of the movable member 631, so as to prevent the movable member 631 from deflecting and to make the movable member 631 move stably to the first position or the second position.

[0158] In one embodiment, as described above, a limiting post 6315 protrudes from one end of the movable member 631 facing the top wall, and a second through hole 615 is opened on the top wall opposite to the first through hole 614, so that the limiting post 6315 is inserted into the second through hole 615.

[0159] Please refer to Figure 16 and Figure 17 In some embodiments of this application, the movable member 631 includes a stop portion 6311 and a plug portion 6313 connected to each other. The plug portion 6313 passes through the first through hole 614. The stop portion 6311 is located in the mounting cavity 613. When the first trigger member 633 is in the second position, the stop portion 6311 abuts against the cavity wall with the first through hole 614. The first trigger member 633 or the first sensing member 635 is disposed on the stop portion 6311.

[0160] In this embodiment, the movable member 631 includes a stop portion 6311 and a plug portion 6313 connected to each other. The width of the stop portion 6311 in at least one direction perpendicular to the length direction of the movable member 631 is greater than the width of the plug portion 6313 and the first through hole 614 in that direction. This arrangement allows the plug portion 6313 to pass through the first through hole 614 and the stop portion 6311 to be disposed in the mounting cavity 613. When the movable member 631 is not subjected to other external forces, the first reset member 65 applies an outward moving force to the movable member 631. Since the stop portion 6311 cannot pass through the first through hole 614 and abut against the cavity wall where the first through hole 614 is provided, the movable member 631 can be limited to the second position, preventing the movable member 631 from falling completely out of the mounting cavity 613. At this time, by setting the first trigger 633 or the first sensor 635 of the sensing module 63 on the stop portion 6311, it can be ensured that the first sensor 635 or the first trigger 633 set on the movable part 631 is always kept in the mounting cavity 613, and the first sensor 635 or the first trigger 633 on the movable part 631 is prevented from being affected by foreign objects.

[0161] Please refer to Figure 18In some embodiments of this application, a positioning structure 616 is provided in the mounting cavity 613, and the positioning structure 616 forms a positioning area 6161 in the mounting cavity 613, and a portion of the movable part 631 is limited and installed in the positioning area 6161.

[0162] In this embodiment, a positioning structure 616 is provided in the mounting cavity 613. The positioning structure 616 can divide the mounting cavity 613 into a positioning area 6161 for mounting the movable part 631. The positioning area 6161 can be completely enclosed by the positioning structure 616. For example, the positioning structure 616 can be set as a perimeter surrounding the movable part 631 or at least two positioning parts arranged at intervals along the circumference of the movable part 631. The positioning area 6161 can also be formed by the positioning structure 616 and the cavity wall of the mounting cavity 613. Placing part of the movable part 631 in the positioning area 6161 can also prevent the movable part 631 from deflecting, so that the movable part 631 can move stably to the first position or the second position, thereby improving the detection accuracy of the position detection module 60.

[0163] Please refer to Figure 17 In some embodiments of this application, the first sensing element 635 has a transmitting part 6351 and a receiving part 6353 disposed opposite to each other, and the first triggering element 633 is a shielding structure; when the movable element 631 moves between the first position and the second position, the first triggering element 633 moves in and out between the transmitting part 6351 and the receiving part 6353.

[0164] In this embodiment, the sensing module 63 includes a transmitter 6351 and a receiver 6353 arranged opposite to each other. The first trigger member 633 is configured as a blocking structure and can move between the transmitter 6351 and the receiver 6353 when the movable member 631 moves between the first position and the second position, so as to block or prevent the receiver 6353 from receiving the signal emitted by the transmitter 6351. In this configuration, the receiver 6353 can normally receive the signal sent by the transmitter 6351, in which case the movable member 631 is in the second position and the first trigger member 633 is located outside the transmitter 6351 and the receiver 6353. In the trigger configuration, the receiver 6353 cannot receive the signal sent by the transmitter 6351, in which case the movable member 631 is in the first position and the first trigger member 633 is positioned between the transmitter 6351 and the receiver 6353. With this configuration, when the receiver 6353 cannot normally receive the signal sent by the transmitter 6351, the first sensor 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0165] Alternatively, the normal state can be that the receiving unit 6353 cannot receive the signal sent by the transmitting unit 6351. In this case, the movable member 631 is in the second position, and the first trigger member 633 is disposed between the transmitting unit 6351 and the receiving unit 6353. The trigger state can be that the receiving unit 6353 can normally receive the signal sent by the transmitting unit 6351. In this case, the movable member 631 is in the first position, and the first trigger member 633 is located outside the transmitting unit 6351 and the receiving unit 6353. With this configuration, when the receiving unit 6353 can normally receive the signal sent by the transmitting unit 6351, the first sensing member 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0166] The first sensing element 635 can be a photoelectric switch, and the transmitting part 6351 can emit light signals to the receiving part 6353. For example, the receiving part 6353 can receive the light signal as the normal state, and the receiving part 6353 cannot receive the light signal sent by the transmitting part 6351 as the trigger state. When the receiving part 6353 cannot receive the light signal sent by the transmitting part 6351 normally, the first sensing element 635 generates a sensing signal to indicate that the measured moving structure has moved a preset distance or moved to a preset position.

[0167] Alternatively, the receiver 6353 can also be a Hall sensor, with the transmitter 6351 configured as a magnet 53 and the first trigger 633 configured as a magnetic shield. When the first trigger 633 is positioned between the transmitter 6351 and the receiver 6353, the Hall sensor cannot sense the magnetic field or the sensed magnetic field strength weakens. The normal state can be defined as when the Hall sensor senses a strong magnetic field, i.e., when the first trigger 633 is located outside the transmitter 6351 and the receiver 6353. The trigger state can be defined as when the first trigger 633 is positioned between the transmitter 6351 and the receiver 6353, and the Hall sensor senses a weaker or no magnetic field. When the Hall sensor senses a weaker or no magnetic field, the first sensor 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or to a preset position.

[0168] Of course, the first sensing element 635 can also be of other structural types, such as microwave sensors, which will not be elaborated here.

[0169] Please refer to Figure 16 and Figure 17 In some embodiments of this application, the first trigger 633 is disposed on the movable member 631, and the first sensing member 635 is connected to the mounting shell 61.

[0170] Understandably, the first sensor 635 is an electronic device, which typically requires power and feedback sensing signals. In some embodiments, the first sensor 635 can be self-powered and can provide feedback sensing signals wirelessly. In other embodiments, the first sensor 635 needs to be connected to wires to receive power and provide feedback sensing signals, or, as in the following embodiments, the first sensor 635 is mounted on the circuit board 67. Therefore, in this embodiment, the first sensor 635 is fixed in the mounting cavity 613, and the first trigger 633 is located on the movable part 631 and moves with the movable part 631. This arrangement avoids the wires connected to the first sensor 635 being pulled due to the movement of the first sensor 635, thereby reducing the risk of wire breakage or damage, improving the stability of the electrical connection of the first sensor 635, and ensuring the stable performance of the position detection module 60.

[0171] Please refer to Figure 16 and Figure 17 In some embodiments of this application, the position detection module 60 further includes a circuit board 67, which is disposed in the mounting cavity 613, and the first sensing element 635 is disposed on the circuit board 67 and electrically connected to the circuit board 67.

[0172] In this embodiment, the position detection module 60 further includes a circuit board 67 disposed in the mounting cavity 613. The first sensor 635 is disposed on the circuit board 67 and electrically connected to the circuit board 67. The circuit board 67 can be used to provide power to the first sensor 635, and can also be used to process and forward the sensing signals generated by the first sensor 635. The circuit board 67 can be equipped with a power supply to provide the power required by the circuit board 67 and the first sensor 635, or it can be connected to an external power source. In addition, a wireless communication module can be disposed on the circuit board 67 for sending and receiving sensing signals, etc. The sensing signals can also be transmitted through wired communication, which is not limited here.

[0173] Please refer to Figure 15 and Figure 17 In some embodiments of this application, the mounting housing 61 has a connection port 617 that communicates with the mounting cavity 613, and the circuit board 67 has a connector 671 facing the connection port 617.

[0174] In this embodiment, a connection port 617 communicating with the mounting cavity 613 is provided on the mounting housing 61, and a connector 671 for plugging in power lines and signal lines is provided on the circuit board 67. The power lines and signal lines can be integrated into the same conductor. With this configuration, the conductor or the plug-in connector mating with the connector 671 can pass through the connection port 617 and connect to the connector 671, thereby providing power to the circuit board 67 and transmitting signals to the circuit board 67.

[0175] Please refer to Figure 19 In some embodiments of this application, the laser 100 further includes a ranging module 70, which is disposed on the laser module 20 and is used to detect the distance between the laser module 20 and the processing position.

[0176] In this embodiment, the laser module 20 is height-adjustable to allow processing at different heights. In this embodiment, a ranging module 70 is provided in the laser 100. The ranging module 70 can be used to detect the distance between the focal point of the laser module 20 and the surface of the object being processed. The ranging module 70 can be an ultrasonic ranging structure, a photoelectric ranging structure, a laser ranging structure, or a contact ranging structure, etc. Ultrasonic ranging, photoelectric ranging, and laser ranging can respectively calculate the distance using the propagation time of sound waves, infrared light, and laser light. The contact ranging structure can calculate the distance by measuring the descent distance of the ranging module 70 until it contacts the processing position.

[0177] Please refer to Figures 19 to 25 In some embodiments of this application, the ranging module 70 includes a housing 71, a circuit board 72, a pin 73, and a detection mechanism 74. The housing 71 has a receiving cavity 713 and a first opening and a second opening communicating with the receiving cavity 713. The circuit board 72 covers the first opening. The pin 73 is vertically and vertically inserted through the second opening and is partially located within the receiving cavity 713. The pin 73 has a starting position and a trigger position located above the starting position. The detection mechanism 74 is disposed in the receiving cavity 713. The detection mechanism 74 includes a second trigger 741 and a second sensor 742. The second trigger 741 is connected to the pin 73. The second sensor 742 is disposed on the surface of the circuit board 72 facing the receiving cavity 713 and is electrically connected to the circuit board 72. When the pin 73 is in the trigger position, the second trigger 741 triggers the second sensor 742.

[0178] In this embodiment, the ranging module 70 is located to the side of the laser module 20 and near the light output port 23, thereby enabling more accurate measurement of the distance between the processing position below the light output port 23 and the laser module 20. The ranging module 70 consists of a housing 71, a circuit board 72, a push pin 73, and a detection mechanism 74. The housing 71 has a receiving cavity 713, a first opening communicating with the receiving cavity 713 on the side wall of the housing 71, and a second opening communicating with the receiving cavity 713 on the bottom wall of the housing 71. The circuit board 72 is covered by the first opening, and a terminal block 721 can be installed on the surface of the circuit board 72 exposed in the receiving cavity 11 for connecting power supply and control system, etc. The push pin 73 extends along the lifting direction of the laser module 20 and passes through the second opening at the bottom of the receiving cavity 713, so that the push pin 73 can be lifted and lowered relative to the housing 71, and has a starting position and a trigger position above the starting position. The detection mechanism 74 is located in the receiving cavity 11. The second trigger 741 of the detection mechanism 74 is connected to the ejector pin 73, and the second sensor 742 of the detection mechanism 74 is located on the circuit board 72 and electrically connected to the circuit board 72; thus, the detection mechanism 74 is prevented from being contaminated by smoke and oil during processing. The second trigger 741 of the detection mechanism 74 is connected to a portion of the ejector pin 73 inserted into the receiving cavity 713, so as to switch between the starting position and the trigger position as the ejector pin 73 rises and falls. When the ejector pin 73 is not subjected to other external forces, the ejector pin 73 can fall to the starting position under its own weight or under the action of the second reset member in the following embodiment. When ranging is required, the laser module 20 is controlled to descend so that the ranging module 70 descends along with it. After the ejector pin 73 abuts against the position to be processed, the laser module 20 and the ranging module 70 continue to descend so that the ejector pin 73 retracts into the receiving cavity 713 until it rises to the trigger position. The second trigger 741 triggers the second sensor 742. After the second sensor 742 generates a sensing signal, it is transmitted to the control system via the circuit board 72. At this point, only the distance between the lower end face of the ejector pin 33 and the laser focus or the light outlet of the laser module 20 in this state needs to be known. By obtaining the descent distance of the laser module 20, the distance between the focus of the laser module 20 and the position to be processed can be calculated. After triggering the second sensor 742, the laser module 20 can be controlled to move upward a fixed distance. This distance is the distance between the lower end face of the ejector pin 73 of the ranging module 70 and the focus of the laser module 20 when the ejector pin 73 is in the triggered position, thereby ensuring that the focus of the laser module 20 falls on the position to be processed, improving processing accuracy. The descent distance of the laser 100 or the laser module 20 can be obtained based on the working distance of the driving components such as the motor or cylinder that drive the laser 100 or the laser module 20 to rise and fall.

[0179] The second sensing element 742 can be configured as a Hall sensor, photoelectric switch, proximity switch, grating reading head, etc. For example, if the second sensing element 742 is a Hall sensor and the second trigger element 741 is a magnet, when the second trigger element 741 moves between the trigger position and the starting position with the ejector pin 73, the magnetic field strength around the Hall sensor changes, for example, from weak to strong or from strong to weak. Using the magnetic field strength detected by the Hall sensor when the second trigger element 741 is in the trigger position as the trigger condition, the Hall sensor can emit a sensing signal when the second trigger element 741 reaches the trigger position. If a proximity switch is used as the second sensing element 742, the second trigger element 741 can touch the sensing surface of the proximity switch when the ejector pin 73 is in the trigger position, thereby causing the proximity switch to emit a sensing signal. If a grating reading head is used as the second sensing element 742, and the second trigger element 741 is a scale grating extending along the movement direction of the ejector pin 73, when the ejector pin 73 moves from the starting position to the trigger position, the scale grating and the grating reading head move relative to each other. The grating reading head can read the displacement relative to the scale grating and convert the displacement into an electrical signal. This signal is then processed by a signal processing circuit to obtain displacement data, thereby generating a sensing signal when the second trigger element 741 moves the corresponding distance from the starting position to the trigger position. The usage of other structures as the detection mechanism 74 will not be described in detail here.

[0180] Optionally, the housing 71 is provided with a limiting notch 719, and at least a portion of the structure of the circuit board 72 is disposed in the limiting notch 719 to limit the circuit board 72 and improve the installation stability of the circuit board 72.

[0181] Please refer to Figure 22 In some embodiments of this application, the ranging module 70 further includes a second reset member disposed in the receiving cavity 713 and acting between the housing 71 and the ejector pin 73, so that the ejector pin 73 tends to remain in the initial position.

[0182] In this embodiment, a second reset member is provided in the ranging module 70. The second reset member can be an elastic element such as a spring, gas spring, or elastic airbag. The elastic element can be disposed on the top wall side opposite to the second opening and apply an elastic thrust toward the ejector pin 73, causing the ejector pin 73 to tend to move from the trigger position to the response position and remain in the response position. Alternatively, the elastic element can be disposed on the cavity wall with the second opening and connected to the ejector pin 73 to apply an elastic pull to the ejector pin 73, which can also cause the ejector pin 73 to tend to move from the trigger position to the response position and remain in the response position. The second reset member can also be a magnetic structure, which can include a first magnetic element and a second magnetic element respectively disposed on the ejector pin 73 and the housing 71. There can be a magnetic attraction between the first magnetic element and the second magnetic element, which causes the ejector pin 73 to tend to move from the trigger position to the response position and remain in the response position. There can also be a magnetic repulsion between the first magnetic element and the second magnetic element, which can be used to push the ejector pin 73 to tend to move from the trigger position to the response position and remain in the response position. When the ejector pin 73 moves into the mounting cavity 613 under external force, it overcomes the force applied by the second reset member. When the external force on the ejector pin 73 is removed, the force applied by the second reset member to the ejector pin 73 will move the ejector pin 73 to the response position. This configuration ensures that the ejector pin 73 remains stably in the initial position when it does not need to be supported by the position to be processed, and allows a downward force to be applied to the ejector pin 73, preventing the ejector pin 73 from being subjected to a reaction force when it initially contacts the position to be processed, which could cause it to bounce upwards and falsely trigger the second sensor 742.

[0183] Please refer to Figure 22 and Figure 23 In some embodiments of this application, the second trigger 741 includes a fixing part 7411 and a trigger part 7412. The fixing part 7411 is sleeved on and fixed to the ejector pin 73, and the trigger part 7412 is connected to the end of the fixing part 7411 near the circuit board 72 and extends upward. This arrangement allows the mounting position of electronic components such as the circuit board 72 to be as far away as possible from the light outlet 23 of the laser module 20, thereby keeping them away from the processing position and the laser, preventing dust and other impurities from adhering to the electronic components such as the circuit board 72, and preventing the heat generated during processing from affecting the performance of the electronic components.

[0184] Please refer to Figure 23In some embodiments of this application, the second trigger 741 is provided with a screw hole 7413, and at least a portion of the outer surface of the ejector pin 73 is provided with external threads. The screw hole 7413 mates with the external threads to allow the second trigger 741 to be threadedly connected to the ejector pin 73. This arrangement facilitates the assembly and disassembly of the second trigger 741 and the ejector pin 73, and allows adjustment of the mounting height of the second trigger 741 on the ejector pin 73, thereby adjusting the distance between the starting position and the trigger position of the ejector pin 73 to suit different processing requirements.

[0185] Please refer to Figures 21 to 23 In some embodiments of this application, the housing 71 includes a base 711 and a dustproof seat 712. A first receiving space 7131 is formed inside the base 711. The side wall of the base 711 is provided with a communication port 714 communicating with the first receiving space 7131. The dustproof seat 712 covers the outer wall of the base 711 with the communication port 714. A second receiving space 7132 is formed inside the dustproof seat 712. The second receiving space 7132 communicates with the first receiving space 7131 to form a receiving cavity 713. The side of the dustproof seat 712 away from the base 711 is provided with a first opening, and the base 711 is provided with a second opening. A pin 73 is inserted into the first receiving space 7131. A second trigger 741 passes through the communication port 714 from the first receiving space 7131 and extends to the second receiving space 7132.

[0186] Please refer to Figure 20 and Figure 22 In some embodiments of this application, the dustproof seat 712 is provided with an extension 716 protruding from the top of the base 711. The extension 716 covers the side of the laser module 20. The extension 716 is provided with a dustproof cavity 717 and a clearance opening communicating with the dustproof cavity 717. The clearance opening and the first opening are located on the same side of the dustproof seat 712. The circuit board 72 is covered by the clearance opening. Some components on the circuit board 72 are located on the surface of the circuit board 72 facing the dustproof cavity 717.

[0187] In this embodiment, the dustproof base 712 includes a main body covering the side of the base 711 and an extension 716 protruding from the top of the base 711. The circuit board 72 is covered on the surface of the dustproof part 361 facing away from the base 711, and a portion of the circuit board 72 is covered on the extension 716. The extension 716 has a dustproof cavity 717 and a clearance opening communicating with the dustproof cavity 717. The clearance opening and the first opening are located on the same side. The circuit board 72 is covered on the clearance opening, so that some components on the circuit board 72 are placed in the dustproof cavity 717 to protect the components on the circuit board 72 and prevent the components from being contaminated with dust, oil, and other impurities, which would affect their performance stability.

[0188] Optionally, the dustproof cavity 717 and the second receiving space 7132 can be interconnected; optionally, the clearance opening and the first opening can be configured as an integral opening or as two independent openings.

[0189] In some embodiments, the side of the laser module 20 is provided with a first heat sink 42 or a second heat sink 43. In this case, the extension 716 can be covered on the surface of the first heat sink 42 or the second heat sink 43.

[0190] Please refer to Figure 19 and Figure 20 In some embodiments of this application, the extension 716 is provided with one of a limiting groove 432 and a limiting protrusion 718 on the surface facing the laser module 20, and the other of a limiting groove 432 and a limiting protrusion 718 is provided on the side of the laser module 20, with the limiting protrusion 718 inserted into the limiting groove 432.

[0191] In this embodiment, a limiting protrusion 718 can be provided on the extension 716, and a limiting groove 432 can be provided on the side of the laser module 20; alternatively, the limiting protrusion 718 can be provided on the side of the laser module 20, and the limiting groove 432 can be provided on the extension 716. When the ranging module 70 is installed, the limiting protrusion 718 is inserted into the limiting groove 432, thereby improving the connection strength between the ranging module 70 and the laser module 20, and limiting the ranging module 70 to prevent it from being misaligned by external forces, thus affecting the detection accuracy.

[0192] It should be noted that in this embodiment, the limiting protrusion 718 or the limiting groove 432 can be directly provided on the side wall of the laser module 20, or the limiting protrusion 718 or the limiting groove 432 can be provided on the first heat sink 42 or the second heat sink 43 installed on the side of the laser module 20. There is no limitation here.

[0193] Please refer to Figure 21 and Figure 22 In some embodiments of this application, the top wall of the receiving cavity 713 is provided with an insertion hole 715. The insertion hole 715 is positioned opposite to one end of the ejector pin 73 inserted into the receiving cavity 713, and the ejector pin 73 can be inserted into the insertion hole 715. This arrangement allows the insertion hole 715 in the top wall of the receiving cavity 713 to avoid obstructing the ejector pin 73, ensuring that the ejector pin 73 can be inserted into the insertion hole 715 at least during its ascent. This eliminates the need to adapt the height of the receiving cavity 713 to the ejector pin 73, reducing the volume of the ranging module 70. Furthermore, the insertion hole 715 also guides and limits the ejector pin 73, preventing it from being blocked during its ascent. Alternatively, the ejector pin 73 can be inserted into the insertion hole 715 only after reaching a certain height, or it can be always inserted into the insertion hole 715; this is not limited here.

[0194] Please refer to Figure 4 In some embodiments of this application, the sidewall of the housing 10 is provided with a conductive structure 17, and the laser module 20 is electrically connected to the conductive structure 17.

[0195] In this embodiment, when the laser 100 is applied to the laser device 1, it is electrically connected to the device body 200 through the conductive structure 17 provided on the side wall of the housing 10 to supply power to the laser module 20 inside the housing 10. With this configuration, there is no need to provide wires to connect the external power supply of the laser 100 and the laser module 20, avoiding the wires between the external power supply and the laser module 20 from affecting the lifting and lowering of the laser module 20. Furthermore, there is no need to provide wires between the laser 100 and the device body 200. The conductive structure 17 can be set as one of a male and a female connector, and the other of a male and a female connector can be set at the installation position of the laser 100 on the laser device 1. An electrical connection can be formed by mating the male and female connectors, reducing the use of wires and making the overall structure of the laser device 1 more organized.

[0196] Please refer to Figure 10 In some embodiments of this application, a converter plate 80 is provided in the accommodating cavity 11. The converter plate 80 may be a circuit board 72 or simply a conductive device. The conductive structure 17 passes through the side wall of the outer casing 10 and is electrically connected to the converter plate 80. The laser module 20 and other electronic devices in the accommodating cavity 11 can then be electrically connected to the converter plate 80, and power can be supplied to each electronic device through the converter plate 80. The converter plate 80 can also be used to receive, process, and transmit data signals and control signals, thereby enabling information interaction between the laser 100 and the main body of the device 200.

[0197] Additionally, a connecting structure 16 can be provided on the side wall of the outer casing 10 for fixing the laser 100 to the main body 200 of the laser device 1. The laser 100 can be installed via plug-in, snap-fit, bolt, magnetic connection, etc., and is not limited here. This allows the laser 100 to be electrically connected while installed on the main body 200, improving installation convenience. In some embodiments, the laser 100 includes an air nozzle module 50, and an installation port 13 is provided on the outer casing 10 of the laser 100 for connecting to an air source. In this case, an air outlet can be provided on the main body 200, so that when the laser 100 is installed on the main body 200, the air outlet and the installation port 13 are directly aligned and connected.

[0198] Please refer to Figure 1This application also proposes a laser device 1, which includes a device body 200 and a laser 100 as described in any of the foregoing embodiments. The laser device 1 can be a laser engraving machine, a laser marking machine, a laser cutting machine, etc. The device body 200 of the laser device 1 can be a frame, with the laser 100 fixed to the device body 200 via a housing 10, or a translation component 230 can be provided on the device body 200, with the laser 100 fixed to the translation component 230, thereby allowing the laser 100 to be translated to move to different processing positions.

[0199] Since the laser device 1 proposed in this application applies all the technical solutions of all the foregoing embodiments, it has at least all the beneficial effects brought by all the foregoing technical solutions, which will not be elaborated here.

[0200] Please refer to Figure 4 , Figure 26 as well as Figure 27 In some embodiments of this application, the housing 10 of the laser 100 is provided with a mounting port 13 communicating with the accommodating cavity 11. The laser 100 also includes an air inlet connector 90 communicating with the air guide channel 514. The air inlet connector 90 is provided at the mounting port 13. When the laser 100 is provided on the mounting surface, the air inlet connector 90 and the air path interface 21b are mutually connected.

[0201] In this embodiment, a nozzle module 50 is provided in the laser 100. The nozzle module 50 covers the outside of the light output port 23 of the laser module 20 and has a gas guide channel 513, a flow guide cavity 521, and an outlet 522 connected in sequence. The light output port 23 is located in the flow guide cavity 521, and the outlet 522 is coaxially arranged with the light output port 23, so that the laser can be emitted through the outlet 522. In addition, an installation port 13 is provided on the housing 10 of the laser 100. An air inlet connector 90 is installed in the installation port 13, and a gas guide hose 55 is provided in the accommodating cavity 11. The gas guide hose 55 can be bent and deformed as needed. The gas guide hose 55 can be made of materials such as plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), and PP (polypropylene). One end of the gas guide hose 55 is connected to the air inlet connector 90, and the other end of the gas guide hose 55 is connected to the gas guide channel 513 of the nozzle module 50.

[0202] On the main body 200 of the laser device 1, a back plate 210 for mounting the laser 100 is provided. One side of the back plate 210 is a mounting surface for mounting the laser 100. An air inlet channel 21a is provided in the back plate 210, and an air passage interface 21b communicating with the air inlet channel 21a is provided on the mounting surface of the back plate 210. The air inlet channel 21a can extend through both sides of the back plate 210, and the opening at the other end of the air inlet channel 21a away from the mounting surface can be used to connect to an air supply structure 300 such as an air pump. When the laser 100 is mounted on the mounting surface of the back plate 210, the mounting port 13 on the side wall of the laser 100 housing 10 is opposite to and communicates with the air passage interface 21b on the mounting surface, thereby allowing the laser 100 to communicate with the air supply structure 300 such as an air pump through the air inlet channel 21a. This configuration allows the installation of the laser 100 and the connection of the gas supply to the laser 100 to be performed simultaneously. The gas supply is already connected when the laser 100 is installed, eliminating the need to connect the gas supply before or after the installation of the laser 100, thus improving the ease of installation and removal of the laser 100.

[0203] During laser processing, the air supply structure 300, such as the air pump, drives the airflow from the air inlet channel 21a and the mounting port 13 into the air nozzle module 50. The airflow is blown out from the outlet 522 through the guide cavity 521. This arrangement can blow away the dust and smoke outside the outlet 522, and the continuous airflow can also prevent dust and other impurities from entering the guide cavity 521 and entering the light output port 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting the laser output.

[0204] Please refer to Figure 27 and Figure 28 In some embodiments of this application, a sealing ring 21d is sandwiched between the laser 100 and the back plate 210, and the sealing ring 21d is arranged circumferentially around the gas passage interface 21b.

[0205] In this embodiment, a sealing ring 21d is provided between the laser 100 and the back plate 210, and the sealing ring 21d is arranged circumferentially around the gas passage interface 21b. The sealing ring 21d can be made of elastic materials such as rubber, silicone, or silicone rubber. When the laser 100 and the back plate 210 clamp the sealing ring 21d, the sealing ring 21d can undergo elastic deformation and adhere tightly to the back plate 210 and the laser 100 respectively, so that the sealing ring 21d, the laser 100, and the back plate 210 form a sealed cavity, improving the sealing performance between the mounting port 13 and the gas passage interface 21b and avoiding air leakage. The sealing ring 21d can be fixed to the back plate 210 or to the outer shell 10 of the laser 100, which is not limited here.

[0206] Please refer to Figure 28In some embodiments of this application, the mounting surface is recessed with a fixing groove 21f, the mounting opening 13 is opened on the bottom wall of the fixing groove 21f, and the sealing ring 21d is provided in the fixing groove 21f and protrudes from the mounting surface.

[0207] In this embodiment, the sealing ring 21d is fixed to the back plate 210 of the main body 200 of the device. Therefore, when other lasers 100 need to be replaced, it is not necessary to install the sealing ring 21d on each laser 100, reducing the usage of the sealing ring 21d. The mounting surface of the back plate 210 has a recessed fixing groove 21f, with the gas passage interface 21b located on the bottom wall of the fixing groove 21f. The sealing ring 21d is installed in the fixing groove 21f, surrounding the gas passage interface 21b. The fixing groove 21f limits the sealing ring 21d, preventing it from shifting and failing to surround the gas passage interface 21b and the outer periphery of the mounting port 13. Furthermore, a portion of the sealing ring 21d protrudes from the fixing groove 21f, ensuring that the laser 100 can abut against the sealing ring 21d when mounted on the mounting surface, thus achieving better sealing performance.

[0208] Please refer to Figure 27 and Figure 28 In some embodiments of this application, the device body 200 further includes a locking member 21e, which fixes the sealing ring 21d to the back plate 210.

[0209] In this embodiment, a locking member 21e is provided on the device body 200. The locking member 21e acts between the back plate 210 and the sealing ring 21d to fix the sealing ring 21d to the back plate 210. The locking member 21e can be an adhesive structure, such as glue, double-sided tape, or Velcro; it can also be a screw or a detachable structure configured to press the outer or inner ring of the sealing ring 21d. Using the locking member 21e to fix the sealing ring 21d can improve the connection strength between the sealing ring 21d and the back plate 210 and reduce the risk of the sealing ring 21d falling off or shifting.

[0210] Please refer to Figure 28 In some embodiments of this application, the locking member 21e includes a locking part 211e and a pressing part 212e connected to each other. The cross-sectional dimension of the pressing part 212e is larger than that of the locking part 211e. The locking member 21e also has an air outlet 213e that passes through the locking part 211e and the pressing part 212e. The inner ring of the sealing ring 21d has a protruding abutting part 211d. The locking part 211e passes through the sealing ring 21d and is inserted into the air passage interface 21b and fixedly connected to the back plate 210. The pressing part 212e presses the abutting part 211d against the back plate 210.

[0211] In this embodiment, the locking member 21e is used to press the sealing ring 21d onto the back plate 210. Specifically, the locking member 21e includes a locking part 211e and a pressing part connected together. The locking part 211e can pass through the sealing ring 21d and be inserted into the air passage interface 21b, and be connected and fixed to the back plate 210. The pressing part 212e is provided on the outside of the air passage interface 21b. An abutment part 211d is provided on the inner ring of the sealing ring 21d. The abutment part 211d can be arranged around the inner ring of the sealing ring 21d, or it can be provided at a part of the inner ring. For example, at least two abutment parts 211d are arranged at intervals along the inner ring. When the locking part 211e of the locking member 21e is inserted into the air passage interface 21b, the pressing part 212e of the locking member 21e presses against the abutment part 211d of the sealing ring 21d, thereby pressing and fixing the sealing ring 21d onto the back plate 210. Meanwhile, the locking part 21e needs to have an air outlet 213e that passes through the locking part 211e and the pressing part 212e to avoid blocking the air passage interface 21b. The locking part 211e of the locking part 21e and the air passage interface 21b can be an interference fit, or they can be bonded or threaded, etc., which is not limited here.

[0212] In this embodiment, the locking member 21e is used to fix the sealing ring 21d. The locking member 21e can be hidden inside the sealing ring 21d, thereby avoiding the laser 100 from being scratched by the locking member 21e or the laser 100 from being unable to stick tightly to the sealing ring 21d when the laser 100 is fixed to the back plate 210.

[0213] Please refer to Figure 27 In some embodiments of this application, the other end of the air intake channel 21a away from the air passage interface 21b is opened on the top surface of the back plate 210.

[0214] In this embodiment, the opening of the air intake channel 21a for connecting the air supply structure 300 is made on the top surface of the back plate 210. With this arrangement, the air pipe 220 connecting the air supply structure 300 and the air intake channel 21a can be connected to the top of the back plate 210, which is away from the processing position and the laser, and facilitates the connection of the air pipe 220.

[0215] Please refer to Figure 26 and Figure 29In some embodiments of this application, the device body 200 is provided with a translation component 230. The translation component 230 can be used to drive the back plate 210 to translate the laser 100 in one direction, or it can be used to drive the laser 100 to translate in different directions. For example, if we define an X direction and a Y direction that are perpendicular to each other, the translation component 230 can be used to drive the back plate 210 and the laser 100 to translate in the X direction or the Y direction. Alternatively, the translation component 230 can include an intersecting first slide rail 2301 and a second slide rail 2302. The second slide rail 2302 is slidably disposed on the first slide rail 2301, and the back plate 210 and the laser 100 are disposed on the second slide rail 2302. The back plate 210 can translate along the second slide rail 2302 in the X direction, and the second slide rail 2302 also drives the back plate 210 and the laser 100 to translate along the first slide rail 2301 in the Y direction.

[0216] The translation component 230 allows the laser 100 to be moved to different positions for processing. Additionally, a first cable chain 240 and a second cable chain 250 are provided in the main body 200. One end of the first cable chain 240 is fixed to the first slide rail 2301, and the other end is connected to the second slide rail 2302. The second cable chain 250 is located on the second slide rail 2302, with one end connected to the second slide rail 2302 and the other end connected to the back plate 210. The air pipe 220, connecting the air supply structure 300 and the air inlet channel 21a, is threaded through the first cable chain 240 and the second cable chain 250.
