[0070] This application proposes a laser 100.

[0071] Please refer to Figure 2 、 Figure 8 and Figure 9, in an embodiment of the present application, the laser 100 includes a housing 10, a laser module 20, and a nozzle module 50. An accommodation cavity 11 is formed in the housing 10, and the bottom of the accommodation cavity 11 has an opening; at least a part of the laser module 20 is disposed in the accommodation cavity 11 in a liftable manner, and the light-emitting port 23 of the laser module 20 is arranged downwardly facing the opening; the nozzle module 50 is disposed below the laser module 20 and has a gas guide channel 513, a diversion cavity 521, and an outlet 522. The diversion cavity 521 is communicated with the gas guide channel 522. The gas guide channel 513 can be connected to a gas source and guide the air flow to the diversion cavity 521, and then blow out from the outlet 522 after passing through the diversion cavity 521. The light-emitting port 23 of the laser module 20 is located in the diversion cavity 521, and the center line of the outlet 522 coincides with that of the light-emitting port 23.

[0072] The laser 100 proposed in the present application can be applied to laser devices 1 such as laser marking machines, laser engraving machines, laser cutting machines, and laser welding machines, and is used to emit laser light for processing operations such as laser marking, laser engraving, laser cutting, and laser welding. Among them, the laser 100 includes a housing 10 as a bearing and installation base. An accommodation cavity 11 is formed in the housing 10, and an opening communicating with the accommodation cavity 11 is provided at the bottom of the housing 10. At least a part of the laser module 20 is arranged in the accommodation cavity 11, and the laser module 20 can be lifted; it can be that the laser module 20 is always located in the accommodation cavity 11 and only lifts in the accommodation cavity 11, and the light-emitting port 23 of the laser module 20 is arranged downwardly facing the opening of the accommodation cavity to emit laser light outward; it can also be that the laser module 20 can be lifted and enter and exit the accommodation cavity 11 from the opening at the bottom of the housing 10. In both cases, the height of the laser module 20 can be adjusted to adjust the height of the laser focus, so that the laser focus can fall on the processing position.

[0073] In addition, a nozzle module 50 is provided in the laser 100. The nozzle module 50 is disposed below the laser module 20. The nozzle module 50 is formed with an air guide channel 513, a diversion cavity 521, and an outlet 522 that are connected in sequence. The light outlet 23 is located in the diversion cavity 521, and the outlet 522 is coaxially arranged with the light outlet 23, so that the laser can be emitted through the outlet 522. When the laser 100 in the embodiment of the present application is used for processing, the nozzle module 50 can be connected to a gas supply structure 300 serving as a gas source. The gas supply structure 300 supplies air flow to the nozzle module 50, and makes the air flow provided by the gas supply structure 300 blow outwards through the air guide channel 513, the diversion cavity 521, and the outlet 522 in sequence. Such an arrangement can blow away the dust and fumes outside the outlet 522, and the continuous air flow can also prevent dust and other impurities from entering the diversion cavity 521, entering the light outlet 23 of the laser module 20, or adhering to the window mirror or the focusing mirror, thereby avoiding affecting the laser emission. And since the nozzle module 50 is fixed on the laser module 20, it can be lifted and lowered together with the laser module 20, so that the nozzle module 50 can always preferably form an air flow at the front end of the nozzle 52 of the laser module 20, and can also make the air flow blow towards the position to be processed, preventing the position to be processed from being contaminated with dust, playing a good dust-proof role, and ensuring the processing effect.

[0074] In this embodiment, by providing the air guide channel 513 in the nozzle module 50, it is not necessary to provide an air pipe extending to the light-emitting position to communicate with the diversion cavity 521, which can play a role in hiding the air path. There will be no air pipe below the laser module 20, thus avoiding the problem that the air pipe is prone to interference with other devices during laser processing, and making the appearance of the laser 100 neat and unified.

[0075] It should be noted that in this embodiment, the nozzle module 50 can be only provided to cover the light outlet 23 and form the diversion cavity 521, or can be a combined structure of a gas guide member 51 and a nozzle 52 in the following embodiment. In addition, the air guide pipe 220 can be directly extended from an external gas source to the accommodation cavity 11 to be connected to the nozzle module 50, or as in the following embodiment, an installation port 13 is opened on the housing 10, an external gas source is connected through the installation port 13, and a gas guide hose 55 is provided in the accommodation cavity 11 to connect the installation port 13 and the nozzle module 50.

[0076] Optionally, the cross-section of the diversion cavity 512 can be tapered along the air outlet direction to play a role in converging the air flow, so that the air flow is concentrated and blown out from the outlet 522, which is beneficial to increasing the blowing force.

[0077] In addition, a lifting module 30 is also provided in the laser 100. The lifting module 30 can be a lead screw drive structure, a cylinder or a hydraulic cylinder pushing structure, a linear motor structure, a worm and gear structure, or a rack and pinion structure, etc., so that the lifting module 30 is in transmission connection with the laser module 20, and thus the laser module 20 and the nozzle module 50 can be driven to lift by the lifting module 30.

[0078] Therefore, it can be understood that in the technical solution of the present application, the laser module 20 in the laser 100 can be lifted under the drive of the lifting module 30 in the housing 10 to adjust the height position of the laser focus; and, a nozzle module 50 is provided to cover the light outlet 23. The nozzle module 50 forms a diversion cavity 521 and is provided with an outlet 522 communicating with the diversion cavity 521. The outlet 522 of the diversion 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 the laser 100 of the present application is used for processing, the nozzle module 50 can be connected to the air supply structure 300. The air supply structure 300 supplies air flow to the nozzle module 50, and the air flow is blown out through the diversion cavity 521 and the outlet 522, so that the dust and fumes outside the outlet 522 can be blown away, and the continuous air flow can also prevent dust and other impurities from entering the diversion cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to the window mirror or the focusing mirror, thereby avoiding affecting the laser emission. And since the nozzle module 50 is fixed on the laser module 20, it can be lifted together with the laser module 20, so that the nozzle module 50 can always form an air flow well at the front end of the nozzle 52 of the laser module 20, and the air flow can also be blown to the position to be processed, preventing the position to be processed from being contaminated with dust, playing a good dust-proof role, and ensuring the processing effect.

[0079] By providing an air guide channel 513 in the nozzle module 50, it is not necessary to provide an air pipe extending to the light-emitting position to communicate with the diversion cavity 521, which can play a role in hiding the air path. There will be no air pipe below the laser module 20, so that the problem that the air pipe is easily interfered with other devices during laser processing can be avoided, and the appearance of the laser 100 is clean and unified.

[0080] In addition, in the laser 100 of the present invention, only some structures such as the laser module 20 and the nozzle module 50 are lifted to adjust the height position of the laser focus and the blowing position, so it is not necessary to lift the entire laser 100 in the laser device 1, making the lifting process of adjusting the heights of the laser module 20 and the nozzle module 50 more convenient.

[0081] Please refer to Figures 9 to 11, in some embodiments of the present application, the nozzle module 50 includes a gas guide member 51, a nozzle 52, and a tracheal connector 56. The gas guide member 51 is disposed below the laser module 20. A gas guide channel 513 is provided in the gas guide member 51. One end of the gas guide channel 513 away from the light exit 23 is provided with an access port for connecting to a gas source. One end of the gas guide member 51 close to the light exit 23 is provided with a first chamber 514 that penetrates through both ends along the center line direction of the light exit 23. The first chamber 514 is communicated with the gas guide channel 513. The nozzle 52 is covered on the side of the gas guide member 51 facing away from the laser module 20. The nozzle 52 is provided with a second chamber 523 and an outlet 522. The second chamber 523 is communicated with the first chamber 514 to form a diversion chamber 521 in combination.

[0082] In this embodiment, the nozzle module 50 includes a gas guide member 51, a nozzle 52, and a tracheal connector 56. Both the nozzle 52 and the gas guide member 51 are covered below the laser module 20. Among them, the gas guide member 51 includes a gas guide portion 511 and a connection portion 512 connected to each other. A gas guide channel 513 is formed in the gas guide portion 511. The connection portion 512 is covered at the position of the light exit 23 and is provided with a first chamber 514. The gas guide channel 513 and the first chamber 514 are communicated with each other through a gas guide port. The nozzle 52 is covered on the side of the gas guide member 51 facing away from the laser module 20 and is connected to the connection portion 512 of the gas guide member 51. It can be that the nozzle 52 and the gas guide member 51 are integrally provided, so as to improve the overall structural stability of the nozzle module 50. Of course, it can also be that the nozzle 52 and the gas guide member 51 are detachably connected. The nozzle 52 is provided with a second chamber 523. The second chamber 523 is communicated with the first chamber 514 to jointly form a diversion chamber 521. An access port is provided at a position of the gas guide member 51 away from the diversion chamber 521. The access port is connected with a tracheal connector, so as to facilitate connecting a trachea, and it is not necessary to directly extend the trachea 220 connecting the gas source to a position close to the light exit 23 of the laser module 20, thereby avoiding the trachea 220 from blocking the light output or causing other influences on the laser processing process.

[0083] Please refer to Figure 12 , in some embodiments of the present application, the nozzle 52 and the gas guide member 51 are detachably connected.

The magnetic conductive member 54 can be arranged as a metal member that can be attracted by the magnet 53, for example, made of iron, cobalt, nickel or the like. The magnetic conductive member 54 can also be arranged as a magnet, and the magnet arranged on the air guide member 51 and the magnet arranged on the air nozzle 52 have opposite magnetic poles to generate magnetic attraction to each other. In addition, the magnetic conductive member 54 is arranged around the circumference of the guide cavity 521, and the magnet 53 can also be arranged around the circumference of the guide cavity 521, or at least two magnets 53 are arranged at intervals along the circumference of the guide cavity 521, so that the air nozzle 52 can be detachably connected to the air guide member 51 through the magnetic attraction between the magnet 53 and the magnetic conductive member 54, and the air nozzle 52 is evenly stressed along the circumference of the guide cavity 521, thereby improving the installation stability.

[0089] In the present embodiment, a limiting step 515 is formed on the surface of the air guide 51 facing the air nozzle 52, and at least a portion of the air nozzle 52 is embedded in the limiting step 515, which can not only play a positioning role when installing the air nozzle 52 and improve the convenience of installation; but also prevent the air nozzle 52 from shifting on the surface of the air guide 51, and ensure that the light outlet 23 of the laser module 20 is arranged relative 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 the present application, the nozzle module 50 further includes a gasket 57, and the gasket 57 is clamped between the nozzle 52 and the air guiding member 51 and is disposed around the air guiding cavity 521.

[0091] In this embodiment, a gasket 57 is disposed between the air guiding member 51 and the nozzle 52, and the gasket 57 is disposed around the air guiding cavity 521; and the gasket 57 generally has elasticity and can be elastically deformed by the extrusion of the air guiding member 51 and the nozzle 52 to closely adhere to the air guiding member 51 and the nozzle 52, improving airtightness and preventing gas from leaking between the nozzle 52 and the air guiding member 51.

[0092] In an embodiment of the present application, a slot 516 is formed on the surface of the air guiding member 51 facing the laser module 20. By setting it in this way, the weight of the air guiding member 51 can be reduced, making the lifting process of the laser module 20 relatively light.

[0093] Please refer to Figure 9 and Figure 10 In some embodiments of the present application, the housing 10 is provided with an installation opening 13, and the laser 100 further includes an air inlet joint 90 and an air guiding hose 55. The air inlet joint 90 is disposed in the accommodation cavity 11 and at the installation opening 13; the air guiding hose 55 extends in a bent manner in the accommodation cavity 11. One end of the air guiding hose 55 is communicated with the air inlet joint 90, and the other end of the air guiding hose 55 is communicated with the air pipe joint 56; wherein, the air guiding hose 55 is adaptively deformed as the laser module 20 moves up and down.

[0094] In the embodiment of the present application, the components such as the laser module 20 in the laser 100 can be moved up and down while maintaining the housing 10 and some structures fixed, so that the process of adjusting the laser focus height can be relatively light. In this embodiment, an installation opening 13 is formed on the housing 10, the air inlet joint 90 is installed at the position of the installation opening 13, and the air guiding hose 55 is disposed in the accommodation cavity 11. The air guiding hose 55 can be bent and deformed according to requirements. The air guiding hose 55 can be made of materials such as plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), and PP (polypropylene). One end of the air guiding hose 55 is connected to the air inlet joint 90, the other end of the air guiding hose 55 is communicated with the air pipe joint 56, and the length of the air guiding hose 55 is greater than the straight-line distance between the nozzle module 50 and the air inlet joint 90, and there is a part of the air guiding hose 55 that is bent; by setting it in this way, when the nozzle module 50 moves up and down with the laser module 20, the air guiding hose 55 can be adaptively deformed to follow the movement of the nozzle module 50, maintaining the connection with the nozzle module 50, making the air flow relatively stable, and ensuring the blowing and dust removal effect.

[0095] In this embodiment, an external air source is connected to the air inlet joint 90 fixed to the housing 10, and the housing 10 does not move up and down in the laser device 1, thereby avoiding the connection structure between the external air source and the laser 100 being pulled as the laser module 20 and the nozzle module 50 move up and down. Moreover, there is no need to reserve a long connection structure to adapt to the lifting of the laser module 20, avoiding interference and improving the stability and safety during the lifting process of the laser module 20.

[0096] Please refer to Figure 9 and Figure 12 , in some embodiments of the present application, the air guiding hose 55 is located on the side of the laser module 20. The air pipe joint 56 includes a first joint 561 and a second joint 562 arranged at an angle. The first joint 561 is inserted into the access port, the second joint 562 is arranged upward, and the second joint 562 is inserted into one end of the air guiding hose 55.

[0097] In this embodiment, the air pipe joint 56 includes a first joint 561 inserted into the access port of the air guiding member 51 and a second joint 562 communicating with the first joint 561. The second joint 562 extends upward along the lifting direction of the laser module 20. Thus, when the air guiding hose 55 is connected to the air pipe joint 56, the air guiding hose 55 extends along the height direction, making the bending deformation direction of the air guiding hose 55 the same as the lifting direction of the laser module 20 and the nozzle module 50. Thereby, interference of the air guiding hose 55 on the lifting of the laser module 20 can be reduced, and the air flow is relatively stable.

[0098] Please refer to Figures 2 to 7 , in some embodiments of the present application, the laser 100 further includes a heat dissipation module 40, and the heat dissipation module 40 is arranged in the accommodation cavity 11.

In addition, the heat dissipation module 40 can move up and down together with the laser module 20, or the heat dissipation module 40 can be fixed to the housing 10, or as in the following embodiment, the heat dissipation fan 41 is fixed to the housing 10, and the heat dissipation fins, etc. are fixed on the laser module 20 to improve the heat dissipation efficiency of the laser module 20.

[0100] Please refer to Figure 9, in some embodiments of the present application, the laser module 20 is provided with a lens barrel 22 inserted into the air guide cavity 521. One end of the lens barrel 22 facing the outlet 522 forms a light outlet 23, and the air guide port for introducing air into the air guide cavity 521 is arranged opposite to the side wall of the lens barrel 22. With this arrangement, the outer side wall of the lens barrel 22 can be used to guide the airflow, so that the airflow flows along the side wall of the lens barrel 22 to the side of the lens barrel 22 facing away from the heat dissipation port 12, and the airflow flows downward and is blown out from the outlet 522.

[0101] In an embodiment of the present application, a window lens is provided at the light outlet 23. With this arrangement, it is possible to prevent dust, smoke, the airflow of the nozzle module 50, etc. from entering the laser module 20 through the light outlet 23.

[0102] In some embodiments, the laser module 20 can include a laser generator 21 and a lens barrel 22. The laser generator 21 is used to generate laser, and the lens barrel 22 is arranged at the light output position of the laser generator 21. Only a window lens can be arranged in the lens barrel 22, and the focusing lens can be arranged in the laser generator 21; alternatively, the lens barrel 22 can include a connected focusing lens group 222 and a window lens group 221, that is, both the focusing lens and the window lens are arranged in the lens barrel 22, so as to facilitate 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 can be detachably connected. For example, the window lens group 221 is sleeved or threadedly connected to the focusing lens group 222.

[0103] Please refer to Figures 3 to 7 , in some embodiments of the present application, a heat dissipation port 12 communicating with the accommodation cavity 11 is provided at the top of the housing 10. The laser device 100 further includes a heat dissipation module 40. The heat dissipation module 40 includes a heat dissipation fan 41. The heat dissipation fan 41 is arranged in the accommodation cavity 11 and is 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 heat dissipation fan 41. The heat dissipation fan 41 is arranged on the top of the laser module 20, and a heat dissipation port 12 is opened on the bottom wall of the accommodation cavity 11. With this arrangement, the heat dissipation fan 41 can drive the outside air to flow into the accommodation cavity 11 and flow downward to dissipate heat from the structures in the accommodation cavity 11. Moreover, the heat dissipation fan 41 is fixedly connected to the housing 10, so that it is not necessary to make the heat dissipation fan 41 move up and down with the laser module 20, making the process of controlling the up and down movement of the laser module 20 more convenient.

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

[0106] In this embodiment, the mounting plate 14 is disposed in the accommodating cavity 11. The mounting plate 14 is fixedly connected to the housing 10, and a ventilation opening 141 is formed in 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 oriented towards the ventilation opening 141. With such a setting, it can not only prevent the cooling fan 41 from being suspended, improving the stability of the cooling fan 41 fixed in the accommodating cavity 11, but also avoid the influence of the setting of the mounting plate 14 on the cooling fan 41 driving the air flow to dissipate heat for structures such as the laser module 20.

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

[0108] In this embodiment, the radiator can be disposed only on one side surface of the laser module 20, or radiators can be disposed on both opposite side surfaces of the laser module 20. A plurality of heat dissipation fins are arranged side by side on the radiator. The radiator can be made of a material with good heat conduction and heat dissipation performance, such as aluminum, aluminum alloy, copper or copper alloy, etc. So that the heat on the laser module 20 can be quickly transferred to the radiator, and the plurality of heat dissipation fins on the radiator form a relatively large heat dissipation area 421, enabling the heat transferred to the radiator to be quickly dissipated.

[0109] Please refer to Figures 5 to 7 , in some embodiments of the present application, the heat dissipation module 40 includes a cooling fan 41 disposed above the laser module 20, and a plurality of heat dissipation fins are arranged horizontally. With such a setting, that is, the heat dissipation fins generally extend along the flow direction of the air flow driven by the cooling fan 41, forming an air flow path between two adjacent heat dissipation fins, so that when the air flow passes through the radiator, it can pass through each air flow path to fully contact each heat dissipation fin and take away the heat on each heat dissipation fin, improving the heat dissipation efficiency of the radiator. Moreover, arranging each heat dissipation fin horizontally also avoids the air flow directly impacting on the surface of the heat dissipation fin and being blocked, affecting the normal flow of the air flow.

[0110] In some embodiments, the lifting module 30 in the laser 100 can be connected to the radiator, and then the laser module 20 can be driven to lift by driving the radiator to lift. For the convenience of description, in the following embodiments, the radiator connected to the lifting module 30 is defined as the first radiator 42, and the heat dissipation fins on the first radiator 42 are the first heat dissipation fins 423; when the heat dissipation module 40 includes two radiators arranged on the two opposite side surfaces of the laser module 20, the other radiator not connected to the lifting module 30 is defined as the second radiator 43, and the heat dissipation fins on the second radiator 43 are the second heat dissipation fins 431.

With such a setting, it can be avoided that the first radiator 42 blocks the disassembly and assembly of the lifting module 30 and the laser module 20, improving the convenience of disassembly and assembly.

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

[0114] In this embodiment, the heat dissipation area 421 and the avoidance area 422 are arranged on the surface of the first heat dissipation area 421 facing away from the laser module 20. The lifting module 30 is arranged in the area where the avoidance area 422 is located to be opposite to and connected to the avoidance area 422, and a plurality of first heat dissipation fins 423 arranged side by side are arranged in the heat dissipation area 421. With such a setting, the overall thickness when the lifting module 30 and the first radiator 42 cooperate with each other can be reduced, and the volume of the laser 100 can be reduced. It should be noted that the avoidance area 422 may not be provided with any first heat dissipation fins 423 at all, or may be provided with some first heat dissipation fins 423 that are shaped like the outer surface of the lifting module 30, improving the space utilization rate and the heat dissipation efficiency of the first radiator 42.

[0115] Combined with reference to Figure 6 and Figure 10 , in some embodiments of the present application, the laser 100 further includes an optical axis 15. The optical axis 15 is arranged in the accommodation cavity 11 and extends along the lifting direction of the laser module 20.

[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, so that the optical axis 15 is used to guide and limit the lifting and lowering of the first heat sink 42 and the laser module 20, thereby improving the stability of the lifting and lowering process of the first heat sink 42 and the laser module 20. Among them, only one optical axis 15 can be provided, and at least two optical axes 15 arranged side by side can also be provided, so that the force can be balanced and multiple limits can be formed, further improving the stability of the lifting and lowering process of the first heat sink 42 and the laser module 20.

[0118] In this embodiment, a sliding hole 424 extending along the height direction of the laser 100 is opened 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 and lowering 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 the present application, a lifting module 30 of the laser 100 is disposed in the accommodating cavity 11, and 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 move up and down.

When the lifting module 30 is applied to the laser 100, the driving member 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 driving member 31 can drive the lifting rod 32 to drive the laser module 20 to rise and fall.

[0121] Please refer to Figure 13 and Figure 14, in some embodiments of the present application, the lifting module 30 further includes a lower dust cover 33. The lower dust cover 33 is sleeved on the part of the lifting rod 32 below the driving member 31. The lower dust cover 33 has a first end and a second end below the first end. The first end is connected to the driving member 31, and the second end is connected to the bottom end of the lifting rod 32. The lower dust cover 33 can expand and contract as the lifting rod 32 moves up and down.

[0122] In this embodiment, a lower dust cover 33 is sleeved on the outside of the lifting rod 32 of the driving member 31. The lower dust cover 33 is telescopically arranged. The lower dust cover 33 can be made of an elastic material, or the lower dust cover 33 can be arranged as a corrugated sleeve in the following embodiment, so that the lower dust cover 33 can contract and expand as the lifting rod 32 moves up and down. Among them, when the lifting module 30 is applied to the laser 100, the lower dust cover 33 is sleeved on the part of the lifting rod 32 below the driving member 31; for the convenience of description, the two ends of the lower dust cover 33 are respectively the first end and the second end, the first end is above the second end, the first end of the lower dust cover 33 is connected to the driving member 31, and the second end is connected to the bottom end of the lifting rod 32. A sealed dust-proof space is formed in the lower dust cover 33, and the opening at the lower end of the driving member 31 for passing through the lifting rod 32 is covered; it can not only prevent dust and oil stains from adhering to the lifting rod 32, but also prevent dust and oil stain impurities from entering the driving member 31 through the opening at the lower end of the driving member 31 for passing through the lifting rod 32; thus, it can prevent dust and oil stain impurities from blocking between the driving member 31 and the lifting rod 32, ensuring that the driving member 31 can drive the lifting rod 32 to move without being blocked by impurities, so as to ensure the smooth and stable operation of the lifting module 30.

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

[0124] In this embodiment, at least part of the lower dust cover 33 is arranged as a corrugated structure composed of a plurality of corrugated segments connected in sequence. Each corrugated segment can be folded relative to each other to shorten the length of the lower dust cover 33, and each corrugated segment of the lower dust cover 33 can also be stretched relative to each other to elongate the length of the lower dust cover 33. Among them, the lower dust cover 33 can be integrally arranged as a telescopable corrugated structure. In this way, the length telescopic change range of the lower dust cover 33 is the largest and the applicable range is wide; it can also be that part of the lower dust cover 33 is arranged as a telescopable corrugated structure. In this way, the shortest contraction length of the lower dust cover 33 can be set by setting the length of the non-corrugated section, avoiding the lower dust cover 33 being punctured by the lifting rod 32 due to excessive contraction and affecting the dust-proof effect.

[0125] Please refer to Figure 13 and Figure 14, in some embodiments of the present application, the lifting module 30 further includes a fixing base 34. The fixing base 34 is provided with a through hole 341. The fixing base 34 is connected to the housing 10. The driving member 31 is disposed on the fixing base 34. The lifting rod 32 passes through the through hole 341 and extends downward, and can move up and down relative to the through hole 341.

[0126] In this embodiment, the lifting module 30 further includes a fixing base 34. The fixing base 34 is used to fix the lifting module 30 at the installation position to be installed on the device. For example, when the lifting module 30 is applied to the laser 100, the fixing base 34 can be fixedly connected to the housing 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 then expand and contract between the fixing base 34 and the bottom end of the lifting rod 32. Among them, 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 at the installation position to be installed, without specially setting a support structure in the device for fixing the lifting module 30.

Among them, the clamping portion 331 can be provided only at one circumferential position of the lower dust cover 33. In some embodiments, the clamping portion 331 can be a sheet-like structure circumferentially surrounded or two or more connecting ears circumferentially distributed.

The protective pad 35 is located on the side of the lower dust cover 33 facing away from the driving member and is connected to the lifting rod 32. The cross-sectional dimension of the protective pad 35 is not less than the cross-sectional dimension of the lower dust cover 33.

[0130] In this embodiment, a protective pad 35 is further provided in the lifting module 30. The protective pad 35 can be made of, but not limited to, materials such as vacuum plates, glass wool, expanded perlite, glass fiber felts, and polystyrene foam boards, etc., so that the protective pad 35 has at least one of the functions of fire prevention, heat insulation, etc. 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; and, the cross-sectional dimension of the protective pad 35 is not less than the cross-sectional dimension of the lower dust cover 33. With such a setting, when the lifting module 30 is applied to a laser device, the lower dust cover 33 can be isolated from the processing position and the laser by the protective pad 35, avoiding the transmission of laser or heat generated during processing to the lower dust cover 33, thereby preventing the lower dust cover 33 from catching fire or being damaged in other forms and improving the use safety. In addition, the setting of the protective pad 35 can also play a certain role in blocking dust and oil, improving the dust-proof performance of the lifting module 30.

[0131] In some embodiments, the cross-sectional profile of the position on the lifting rod 32 for sleeving the protective pad 35 can be made non-circular, and the shape of the socket hole on the protective pad 35 is adapted to the cross-sectional shape of the lifting rod 32, so as to prevent the protective pad 35 from rotating on the lifting rod 32.

[0132] Please refer to Figure 13 and Figure 14 , in some embodiments of the present application, the driving member 31 is a motor, the lifting rod 32 is a lead screw, the motor has a mounting hole 311 penetrating along the length direction of the lead screw, and the lead screw is inserted into the mounting hole 311 and can extend outward from the two 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 member 31 is a motor, and the motor is provided with a mounting hole 311 penetrating along the length direction of the lead screw. The lead screw is inserted into the mounting hole 311 and can extend above and below the driving member 31 from the two ends of the mounting hole 311; the rotor in the motor is threadedly connected to the lead screw, so that the lead screw can be driven to move along the length direction of the lead screw when the rotor rotates. Using the through-type lead screw motor module as the lifting module 30, the space occupied by the lifting module 30 is smaller, and the space above and below the motor can be fully utilized for the movement of the lead screw, thereby reducing the volume of the devices and equipment applying the lifting module 30.

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

[0135] In the foregoing embodiment, the through-type lead screw motor module is used as the lifting module 30. At this time, 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 activity space communicating with the mounting hole 311 is formed in the upper dust cover 36. At this time, the upper dust cover 36 can shield the lead screw and the mounting hole 311, preventing impurities such as dust and oil from adhering to the part of the lead screw protruding from above the motor, and preventing impurities such as dust and oil from entering the motor from the upper opening of the mounting hole 311, so as to avoid blockage of impurities between the driving member 31 and the lifting rod 32, ensuring that the driving member 31 can drive the lifting rod 32 to move without being blocked by impurities and ensuring the smooth and stable operation of the lifting module 30.

[0136] Please refer to Figure 13 and Figure 14 , in some embodiments of the present application, the upper dust cover 36 includes a dust-proof portion 361 and a support portion 362. The support portion 362 covers the motor, the dust-proof portion 361 is connected to one end of the support portion 362 away from the motor and extends along the axial direction of the lifting rod 32. The radial dimension of the support portion 362 is larger than the radial dimension of the dust-proof portion 361, and an activity space is provided in the dust-proof portion 361.

[0137] In this embodiment, the upper dust cover 36 includes a dust-proof portion 361 and a support portion 362. The support portion 362 abuts against the motor, the dust-proof portion 361 is connected to one end of the support portion 362 away from the motor, and is generally in a cylindrical structure and forms an activity space with an opening at the lower side. The radial dimension of the support portion 362 is larger than the radial dimension of the dust-proof portion 361. With such a setting, the contact area with the motor is increased by using the support portion 362, and 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 the present application, the laser 100 further includes a position detection module 60. The position detection module 60 is disposed in the accommodation cavity 11 and is used to detect the position of the laser module 20.

[0139] In the embodiment of the present application, the laser module 20 is arranged to be liftable relative to the housing 10, so that the height of the light outlet 23 of the laser module 20 can be adjusted according to the height of different processing positions, thereby improving the processing accuracy and processing effect. In addition, before each laser processing, the laser module 20 needs to be lifted back to the preset origin position, so as to facilitate controlling the operation of the lifting module 30 to lower the laser module 20 to the required position. In this embodiment, a position detection module 60 is arranged in the laser 100 to detect the position of the laser module 20. Among them, the position detection module 60 can detect the height of the laser module 20, or can be used to detect whether the laser module 20 has been lifted back to the preset origin position, thereby improving the accuracy of adjusting the height of the laser module 20. The position detection module 60 can be at least one of a proximity switch, a photoelectric detection switch, a grating scale detection module, a Hall sensor, etc., and is not limited herein.

[0140] With reference to Figure 6 、 Figure 15 and Figure 16 , in some embodiments of the present application, the position detection module 60 is used to detect whether the laser module 20 has been lifted back to the preset origin position. The position detection module 60 includes a mounting shell 61, an induction module 63 and a first reset member 65. The mounting shell 61 is provided with a mounting cavity 613 and is provided with a first through hole 614 communicating with the mounting cavity 613. The induction module 63 includes a movable member 631, a first trigger member 633 and a first induction member 635. The movable member 631 is movably inserted through the first through hole 614 and has a first position and a second position. One of the first trigger member 633 and the first induction member 635 is arranged on the movable member 631, and the other of the first trigger member 633 and the first induction member 635 is connected to the mounting shell 61. When the movable member 631 is in the first position, the first trigger member 633 triggers the first induction member 635. The first reset member 65 is arranged in the mounting cavity 613 and acts between the mounting shell 61 and the movable member 631 to make the movable member 631 tend to remain in the second position.

[0141] Specifically, the installation shell 61 serves as the installation base of the position detection module 60, and an installation cavity 613 is formed therein. The outer contour of the installation shell 61 can be a cuboid, cube, cylinder, prism, or other regular or irregular structures. The installation cavity 613 formed therein can be shaped to conform to the outer contour or can be set to other shapes. The installation shell 61 can include an upper shell 611 and a lower shell 612 that cover each other, or can be set to a side-opening structure to facilitate opening the installation cavity 613 for disassembly and assembly of the internal structure. The movable member 631 of the induction module 63 passes through the first through hole 614 opened on the installation shell 61 and extends outward from the installation cavity 613. The movable member 631 can slide relative to the installation shell 61 along the central axis direction of the first through hole 614 and has a first position and a second position. Additionally, a first reset member 65 is provided between the movable member 631 and the installation shell 61. The first reset member 65 can be an elastic member such as a spring, gas spring, elastic airbag, etc. The elastic member can be disposed on the top wall side opposite to the first through hole 614 and 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 stay at the second position. The elastic member can also be disposed on the cavity wall where the first through hole 614 is opened and connected to the movable member 631 to apply an elastic pulling force to the movable member 631, which can also make the movable member 631 have a tendency to move from the first position to the second position and stay at the second position. The first reset member 65 can also be a magnetic structure. The magnetic structure can include a first magnetic member and a second magnetic member respectively disposed on the movable member 631 and the installation shell 61. There can be a magnetic attraction force between the first magnetic member and the second magnetic member, and the magnetic attraction force makes the movable member 631 have a tendency to move from the first position to the second position and stay at the second position. There can also be a magnetic repulsion force between the first magnetic member and the second magnetic member, and the magnetic repulsion force can be used to push the movable member 631 so that the movable member 631 has a tendency to move from the first position to the second position and stay at the second position. When the movable member 631 is moved into the installation cavity 613 by an external force, the acting force applied by the first reset member 65 will be overcome. When the external force applied to the movable member 631 is withdrawn, the acting 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 induction module 63 further includes a first trigger 633 and a first sensor 635 disposed in the installation cavity 613. The first sensor 635 can be connected to the installation housing 61, and the first trigger 633 can be arranged on the movable member 631 so that the first trigger 633 moves relative to the first sensor 635 along with the movable member 631. When the movable member 631 moves from the second position to the first position, the first trigger 633 triggers the first sensor 635 to cause the first sensor 635 to emit an induction signal. In the embodiment of the present application, the first trigger 633 can also be connected to the installation housing 61, and the first sensor 635 can be arranged on the movable member 631 to move relative to the first trigger 633 along with the movable member 631. When the movable member 631 moves from the second position to the first position, it can also be the first trigger 633 that triggers the first sensor 635 to cause the first sensor 635 to emit an induction signal.

[0143] Among them, the first sensor 635 can be set as a Hall sensor, an optoelectronic switch, a proximity switch, a grating reader head, etc. For example, the first sensor 635 is a Hall sensor, and the first trigger 633 is set as a magnet 53. When the first trigger 633 moves between the first position and the second position along with the movable member 631, the magnetic field intensity around the Hall sensor changes, such as from weak to strong or from strong to weak. Taking the magnetic field intensity detected by the Hall sensor when the first trigger 633 is in the first position as the trigger condition, the Hall sensor can emit an induction signal when the first trigger 633 reaches the first position. If a proximity switch is used as the first sensor 635, the first trigger 633 can touch the induction surface of the proximity switch when the movable member 631 is in the first position, so that the proximity switch emits an induction signal. If a grating reader head is used as the first sensor 635, the first trigger 633 is a scale grating extending along the moving direction of the movable member 631. When the movable member 631 moves from the second position to the first position, the scale grating and the grating reader head move relative to each other. The grating reader head can read the displacement relative to the scale grating and convert the displacement into an electrical signal, which is processed by a signal processing circuit to obtain displacement data. Thus, an induction signal can be generated when the first trigger 633 moves a corresponding distance from the second position to reach the first position. The usage methods when other structures are used as the induction module 63 are not elaborated here.

[0144] In this embodiment, the movable member 631 is disposed opposite to at least a part of the laser module 20 in the height direction. When the laser module 20 moves upward relative to the mounting case 61 to reset to the origin, the laser module 20 can push the first trigger member 633 upward, and when the laser module 20 moves to the preset origin position, the movable member 631 just moves to the first position to make the first trigger member 633 trigger the first sensing member 635 to emit a sensing signal indicating that the laser module 20 has completed the reset, and the sensing signal is fed back to the controller to control the laser module 20 to stop moving. With such a setting, the laser module 20 can be more precisely controlled to reset to the origin. Since both the first sensing member 635 and the first trigger member 633 of the position sensing module 63 are located in the mounting case 61, dust and oil in the outside world will not affect this part of the structure, which can ensure the stable performance of the position detection module 60, so as to ensure that the position detection module 60 can accurately detect the state information when the laser module 20 reaches the reset position and make a feedback.

[0145] Moreover, since both the first trigger member 633 and the first sensing member 635 are disposed in the mounting cavity 613, they will not be contaminated and interfered by other sundries such as dust and oil in the outside world, thereby reducing the risk of problems such as poor detection or false triggering, and ensuring 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 the present application, the first reset member 65 is an elastic member, and the elastic member is disposed between the movable member 631 and the cavity wall of the mounting cavity 613 along the moving 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, a gas spring, an elastic airbag, etc. The elastic member can be disposed on one side of the top wall opposite to the first through hole 614 and between the top wall and the movable member 631 to apply an elastic thrust toward the first through hole 614 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 stay at the second position.

[0148] The elastic member can also be disposed on the cavity wall provided with the first through hole 614 and connected to the movable member 631 to apply an elastic pulling force to the movable member 631, which can also make the movable member 631 have a tendency to move from the first position to the second position and stay at the second position.

[0149] Specifically, when the movable member 631 is not affected by an external force, the movable member 631 is in the second position under the elastic force of the elastic member. When the movable member 631 is moved into the installation cavity 613 under an external force to reach the first position, the elastic member is deformed elastically under the force and generates an elastic force in the direction opposite to the external force. When the external force applied to the movable member 631 is removed, the elastic member will recover its shape and move the movable member 631 to the second position.

[0150] Please refer to Figure 16 and Figure 17 , in some embodiments of the present application, the installation cavity 613 has a top wall disposed opposite to the first through hole 614. One end of the movable member 631 facing the top wall is provided with a limiting post 6315, and the elastic member is sleeved on the limiting post 6315.

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

[0152] At the same time, a limiting post 6315 protrudes from one end of the movable member 631 facing the top wall. The limiting post 6315 can be integrally formed with the movable member 631, or can be detachably or non-detachably connected to the movable member 631. In addition, the elastic member is sleeved on the limiting post 6315. For example, a spring is sleeved on the limiting post 6315, or the elastic airbag is set as an annular inflatable ring to be sleeved on the limiting post 6315; or the piston rod of the gas spring is set as a hollow rod to be sleeved on the limiting post 6315. With such a setting, the position stability of the elastic member can be improved, the deviation of the elastic member can be avoided, and it is ensured that the elastic member can act on the movable member 631 stably, thus ensuring the stability of the overall structure and performance.

[0153] Please refer to Figure 16 and Figure 17 , in some embodiments of the present application, a limiting hole 6317 is formed at one end of the movable member 631 facing the top wall, and a part 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 limit post 6315 can be integrally formed with the movable member 631. With this arrangement, there is a high connection strength between the limit post 6315 and the movable member 631, and the relative position between the limit post 6315 and the movable member 631 is relatively stable, improving the overall structural stability. In some embodiments, the limit post 6315 can also be detachably connected to the movable member 631. When the limit post 6315 is detachably connected to the movable member 631, a limit hole 6317 can be opened at one end of the movable member 631 facing away from the first through hole 614, and a part of the limit post 6315 can be inserted into the limit hole 6317, thereby also improving the connection strength between the limit post 6315 and the movable member 631, making it difficult for the limit post 6315 to disengage from the movable member 631, thus ensuring that the elastic member acts stably on the movable member 631 and improving the overall structural stability. Additionally, one end of the elastic member facing the movable member 631 can be inserted into the limit hole 6317 to further limit the elastic member. Of course, a counterbore 6319 can also be opened on the end face of the movable member 631, and a limit hole 6317 is opened on the bottom wall of the counterbore 6319, so that one end of the elastic member is inserted into the counterbore 6319 and abuts against the bottom wall of the counterbore 6319, and one end of the limit post 6315 passes through the counterbore 6319 and is inserted into the limit hole 6317.

[0155] In addition, in some embodiments, the limit post 6315 can pass through the cavity wall of the installation cavity 613 opposite to the first through hole 614, thereby providing auxiliary positioning and limiting functions for the movable member 631 to prevent the movable member 631 from skewing; at this time, by improving the connection strength between the limit post 6315 and the movable member 631 and ensuring the relative position stability between the limit post 6315 and the movable member 631, the problem that the limit post 6315 interferes with the movement of the movable member 631 due to the deviation of the limit post 6315 can be avoided.

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

[0157] In this embodiment, a second through hole 615 opposite to the first through hole 614 can be provided in the mounting shell 61. For example, the second through hole 615 is provided in the top wall opposite to the first through hole 614, or a limiting plate is provided in the mounting cavity 613, and the second through hole 615 is 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 such a setting, the first through hole 614 and the second through hole 615 which are oppositely arranged provide positioning and limiting effects for the movable member 631 at different positions in the length direction of the movable member 631, avoiding the deflection of the movable member 631 and enabling the movable member 631 to stably move to the first position or the second position.

[0158] Among them, in the above embodiment, a limiting post 6315 can protrude from one end of the movable member 631 facing the top wall, the second through hole 615 is provided in the top wall opposite to the first through hole 614, and 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 the present application, the movable member 631 includes a stop portion 6311 and a plugging portion 6313 which are connected. The plugging portion 6313 passes through the first through hole 614, the stop portion 6311 is located in the mounting cavity 613, and when the first trigger member 633 is in the second position, the stop portion 6311 abuts against the cavity wall provided with the first through hole 614, and the first trigger member 633 or the first sensing member 635 is provided on the stop portion 6311.

[0160] In this embodiment, the movable member 631 includes a stop portion 6311 and a plugging portion 6313 which are connected. 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 widths of the plugging portion 6313 and the first through hole 614 in this direction; with such a setting, the plugging portion 6313 passes through the first through hole 614, and the stop portion 6311 is arranged in the mounting cavity 613. When the movable member 631 is not affected by 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 abuts against the cavity wall provided with the first through hole 614, the movable member 631 can be limited to the second position, avoiding the complete drop of the movable member 631 from the mounting cavity 613. At this time, by arranging the first trigger member 633 or the first sensing member 635 of the sensing module 63 on the stop portion 6311, it can be ensured that the first sensing member 635 or the first trigger member 633 provided on the movable member 631 is always kept in the mounting cavity 613, avoiding the influence of external foreign objects on the first sensing member 635 or the first trigger member 633 on the movable member 631.

[0161] Please refer to Figure 18, in some embodiments of the present application, a positioning structure 616 is provided in the installation cavity 613. The positioning structure 616 forms a positioning area 6161 in the installation cavity 613, and part of the movable member 631 is limitedly installed in the positioning area 6161.

[0162] In this embodiment, the positioning structure 616 is provided in the installation cavity 613. The positioning structure 616 can divide a positioning area 6161 for installing the movable member 631 in the installation cavity 613. Among them, the positioning area 6161 can be completely surrounded by the positioning structure 616. For example, the positioning structure 616 is set as a surrounding edge arranged along the circumference of the movable member 631 or at least two positioning members arranged at intervals along the circumference of the movable member 631. The positioning area 6161 can also be formed by jointly surrounding the positioning structure 616 and the cavity wall of the installation cavity 613. Setting part of the movable member 631 in the positioning area 6161 can also play a role in preventing the movable member 631 from deflecting, enabling the movable member 631 to stably move to the first position or the second position, and improving the detection accuracy of the position detection module 60.

[0163] Please refer to Figure 17 , in some embodiments of the present application, the first sensing member 635 has a relatively arranged transmitting portion 6351 and receiving portion 6353, and the first triggering member 633 is an occlusion structure. When the movable member 631 moves between the first position and the second position, the first triggering member 633 enters and exits between the transmitting portion 6351 and the receiving portion 6353.

[0164] In this embodiment, the sensing module 63 includes a relatively arranged transmitting portion 6351 and receiving portion 6353. The first triggering member 633 is set as an occlusion structure and can enter and exit between the transmitting portion 6351 and the receiving portion 6353 when the movable member 631 moves between the first position and the second position to occlude or hinder the receiving portion 6353 from receiving the signal emitted by the transmitting portion 6351. Among them, it can be that the normal state is that the receiving portion 6353 normally receives the signal sent by the transmitting portion 6351. At this time, the movable member 631 is in the second position, and the first triggering member 633 is located outside the transmitting portion 6351 and the receiving portion 6353. The triggering state is that the receiving portion 6353 cannot receive the signal sent by the transmitting portion 6351. At this time, the movable member 631 is in the first position, and the first triggering member 633 is disposed between the transmitting portion 6351 and the receiving portion 6353. With such a setting, when the receiving portion 6353 cannot normally receive the signal sent by the transmitting portion 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.

[0165] Alternatively, it can be the normal state that the receiving part 6353 cannot receive the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the second position, and the first trigger part 633 is disposed between the transmitting part 6351 and the receiving part 6353; it is the trigger state that the receiving part 6353 normally receives the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the first position, and the first trigger part 633 is located outside the transmitting part 6351 and the receiving part 6353; thus arranged, when the receiving part 6353 can normally receive the signal sent by the transmitting part 6351, the first sensing part 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0166] Among them, the first sensing part 635 can be an optoelectronic switch, and the transmitting part 6351 can emit an optical signal to the receiving part 6353. For example, it is the normal state that the receiving part 6353 can receive the optical signal, and it is the trigger state that the receiving part 6353 cannot receive the optical signal sent by the transmitting part 6351; when the receiving part 6353 cannot normally receive the optical signal sent by the transmitting part 6351, the first sensing part 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0167] Alternatively, the receiving part 6353 can also be a Hall sensor. The transmitting part 6351 is set as a magnet 53, and the first trigger part 633 is set as a magnetic isolation part. When the first trigger part 633 is disposed between the transmitting part 6351 and the receiving part 6353, the Hall sensor cannot sense the magnetic field or the sensed magnetic field intensity becomes weak. It can be the normal state when the Hall sensor senses a strong magnetic field, that is, when the first trigger part 633 is located outside the transmitting part 6351 and the receiving part 6353, and it is the trigger state when the first trigger part 633 is disposed between the transmitting part 6351 and the receiving part 6353 and the magnetic field intensity sensed by the Hall sensor becomes weak or the magnetic field cannot be sensed; when the magnetic field intensity sensed by the Hall sensor becomes weak or the magnetic field cannot be sensed, the first sensing part 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

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

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

[0170] It can be understood that the first sensing element 635 is an electronic device that usually requires power supply and feedback of sensing signals. In some embodiments, the first sensing element 635 can be self-powered and feedback sensing signals through wireless transmission. In some embodiments, the first sensing element 635 needs to be connected to a wire for receiving electrical energy and feedbacking sensing signals, or the first sensing element 635 is arranged on the circuit board 67 in the following embodiments. Therefore, in this embodiment, the first sensing element 635 is fixed in the installation cavity 613, and the first triggering element 633 is arranged on the movable element 631 to move along with the movable element 631; with such an arrangement, it is avoided that the wire connected to the first sensing element 635 is pulled when the first sensing element 635 moves, thereby reducing the risk of wire breakage or damage, improving the stability of the electrical connection of the first sensing element 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 the present application, the position detection module 60 further includes a circuit board 67. The circuit board 67 is arranged in the installation cavity 613, and the first sensing element 635 is arranged 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 arranged in the installation cavity 613. The first sensing element 635 is arranged on the circuit board 67 and electrically connected to the circuit board 67. The circuit board 67 can be used to provide electrical energy for the first sensing element 635, and can also be used to process and forward the sensing signals generated by the first sensing element 635; among them, a power supply can be arranged on the circuit board 67 to provide the electrical energy required by the circuit board 67 and the first sensing element 635, or the circuit board 67 can be connected to an external power supply; in addition, a wireless communication module can be arranged on the circuit board 67 for sending and receiving sensing signals, etc.; it can also be to transmit sensing signals through wired communication, which is not limited here.

With such an arrangement, the wire or the plug-in seat paired with the connection seat 671 can pass through the connection port 617 to be connected to the connection seat 671, so as to supply power to the circuit board 67 and conduct signal transmission with the circuit board 67.

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

[0176] In the embodiments of the present application, the laser module 20 is made to be liftable so as to adjust the height of the laser module 20 to process processing positions at different heights. In this embodiment, a ranging module 70 is provided in the laser 100, and 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 processed object. Among them, the ranging module 70 can be an ultrasonic ranging structure, an optoelectronic ranging structure, a laser ranging structure or a contact ranging structure, etc. Ultrasonic ranging, optoelectronic ranging and laser ranging can respectively use the propagation time of sound waves, infrared light and lasers for conversion ranging, and the contact ranging structure can measure the descending distance when the ranging module 70 descends until it abuts against the processing position for conversion ranging.

[0177] Please refer to Figures 19 to 25 , in some embodiments of the present application, the ranging module 70 includes a housing 71, a circuit board 72, a thimble 73 and a detection mechanism 74. An accommodation cavity 713, a first opening and a second opening communicating with the accommodation cavity 713 are provided in the housing 71; the circuit board 72 covers the first opening; the thimble 73 is slidably disposed through the second opening and partially located in the accommodation cavity 713. The thimble 73 has a starting position and a trigger position above the starting position; the detection mechanism 74 is disposed in the accommodation cavity 713. The detection mechanism 74 includes a second trigger member 741 and a second sensing member 742. The second trigger member 741 is connected to the thimble 73, and the second sensing member 742 is disposed on the surface of the circuit board 72 facing the accommodation cavity 713 and is electrically connected to the circuit board 72; wherein, when the thimble 73 is in the trigger position, the second trigger member 741 triggers the second sensing member 742.

[0178] In this embodiment, the distance measurement module 70 is located on the side of the laser module 20 and is disposed adjacent to the light exit 23, so that the distance between the processing position to be processed below the light exit 23 and the laser module 20 can be measured more accurately. The distance measurement module 70 is composed of a housing 71, a circuit board 72, a thimble 73, and a detection mechanism 74. The housing 71 is provided with a receiving cavity 713. The side wall of the housing 71 is provided with a first opening communicating with the receiving cavity 713, and the bottom wall of the housing 71 is provided with a second opening communicating with the receiving cavity 713. The circuit board 72 is covered on the first opening. A terminal block 721 can be provided on the surface of the circuit board 72 exposed in the receiving cavity 11 for connecting a power supply, a control system, etc. The thimble 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 thimble 73 is arranged to be liftable relative to the housing 71 and has a starting position and a trigger position above the starting position. The detection mechanism 74 is disposed in the receiving cavity 11. The second trigger member 741 of the detection mechanism 74 is connected to the thimble 73, and the second sensing member 742 of the detection mechanism 74 is disposed on the circuit board 72 and electrically connected to the circuit board 72, thereby preventing the detection mechanism 74 from being contaminated by soot and oil during the processing. The second trigger member 741 of the detection mechanism 74 is connected to the part of the thimble 73 inserted into the receiving cavity 713, so as to switch between the starting position and the trigger position as the thimble 73 moves up and down. When the thimble 73 is not affected by other external forces, the thimble 73 can fall to the starting position under its own gravity or the action of the second reset member in the following embodiment. When distance measurement is required, the laser module 20 is controlled to descend so that the distance measurement module 70 descends accordingly. After the thimble 73 abuts against the processing position to be processed, the laser module 20 and the distance measurement module 70 are continuously lowered so that the thimble 73 retracts into the receiving cavity 713 until it rises to the trigger position. The second trigger member 741 triggers the second sensing member 742. After the second sensing member 742 generates an induction signal, it can be transmitted to the control system through the circuit board 72. At this time, it is only necessary to know the distance between the lower end surface of the thimble 33 and the laser focus or the light exit of the laser module 20 in this state, and the distance between the focus of the laser module 20 and the processing position to be processed can be calculated by obtaining the descending distance of the laser module 20. After triggering the second sensing member 742, the laser module 20 can be controlled to move upward by a fixed distance, and this distance is the distance between the lower end surface of the thimble 73 of the distance measurement module 70 in the trigger position and the focus of the laser module 20, so as to ensure that the focus of the laser module 20 falls on the processing position to be processed and improve the processing accuracy. Among them, the descending distance of the laser 100 or the laser module 20 can be obtained according to the working distance of a driving member such as a motor or a cylinder that drives the laser 100 or the laser module 20 to move up and down.

[0179] Among them, the second sensing element 742 can be set as a Hall sensor, an optoelectronic switch, a proximity switch, a grating reader head, etc. For example, the second sensing element 742 is a Hall sensor, and the second triggering element 741 is set as a magnet. When the second triggering element 741 moves between the triggering position and the starting position along with the thimble 73, the magnetic field intensity around the Hall sensor changes, for example, from weak to strong or from strong to weak. Taking the magnetic field intensity detected by the Hall sensor when the second triggering element 741 is at the triggering position as the triggering condition, an induction signal can be sent out by the Hall sensor when the second triggering element 741 reaches the triggering position. If a proximity switch is used as the second sensing element 742, the second triggering element 741 can touch the sensing surface of the proximity switch when the thimble 73 is at the triggering position, so that the proximity switch sends out an induction signal. If a grating reader head is used as the second sensing element 742, the second triggering element 741 is a scale grating extending along the moving direction of the thimble 73. When the thimble 73 moves from the starting position to the triggering position, the scale grating and the grating reader head move relative to each other. The grating reader head can read the displacement of the relative movement with the scale grating, and convert the displacement into an electrical signal to obtain displacement data through signal processing by a signal processing circuit. Thus, an induction signal can be generated when the second triggering element 741 moves a corresponding distance from the starting position to reach the triggering position. The usage methods of using other structures as the detection mechanism 74 will not be elaborated here.

[0180] Optionally, the housing 71 is provided with a limiting notch 719, and at least part of the structure of the circuit board 72 is arranged 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 the present application, the ranging module 70 further includes a second resetting member, which is arranged in the accommodating cavity 713 and acts between the housing 71 and the thimble 73 to make the thimble 73 tend to stay at the starting position.

[0182] In this embodiment, a second reset member is provided in the distance measuring module 70. The second reset member may be an elastic member such as a spring, a gas spring, an elastic airbag, etc. The elastic member may be provided on one side of the top wall opposite to the second opening and apply an elastic thrust toward the second opening to the ejector pin 73, so that the ejector pin 73 has a tendency to move from the trigger position to the response position and stay at the response position; the elastic member may also be provided on the cavity wall provided with the second opening and connected to the ejector pin 73 to apply an elastic pulling force to the ejector pin 73, which can also make the ejector pin 73 have a tendency to move from the trigger position to the response position and stay at the response position. The second reset member may also be a magnetic structure. The magnetic structure may include a first magnetic member and a second magnetic member respectively provided on the ejector pin 73 and the housing 71. There may be a magnetic attraction force between the first magnetic member and the second magnetic member, and the magnetic attraction force makes the ejector pin 73 have a tendency to move from the trigger position to the response position and stay at the response position; there may also be a magnetic repulsion force between the first magnetic member and the second magnetic member, and the magnetic repulsion force can be used to push the ejector pin 73 so that the ejector pin 73 has a tendency to move from the trigger position to the response position and stay at the response position. When the ejector pin 73 moves into the installation cavity 613 under an external force, the acting force applied by the second reset member will be overcome. When the external force applied to the ejector pin 73 is withdrawn, the acting force applied by the second reset member to the ejector pin 73 will make the ejector pin 73 move to the response position. With such a setting, it can be ensured that the ejector pin 73 stably stays at the starting position when there is no need to abut against the position to be processed, and a downward acting force can be applied to the ejector pin 73 to prevent the ejector pin 73 from bouncing upward due to a reaction force when initially contacting the position to be processed, resulting in mis-triggering of the second sensing member 742.

[0183] Please refer to Figure 22 and Figure 23 , in some embodiments of the present application, the second trigger member 741 includes a fixing portion 7411 and a triggering portion 7412. The fixing portion 7411 is sleeved on and fixed to the ejector pin 73, and the triggering portion 7412 is connected to one end of the fixing portion 7411 close to the circuit board 72 and extends upward. With such a setting, the installation positions of electronic devices such as the circuit board 72 can be as far away as possible from the light outlet 23 of the laser module 20, so as to be far away from the processing position and the laser, avoid adhesion of impurities such as dust to the electronic devices such as the circuit board 72, and avoid the influence of the heat generated during the processing on the performance of the electronic devices.

With such a setting, it is convenient for the disassembly and assembly between the second trigger member 741 and the ejector pin 73, and the installation height of the second trigger member 741 on the ejector pin 73 can be adjusted, so as to adjust the distance between the starting position and the triggering position of the ejector pin 73 to suit different processing requirements.

The extension portion 716 covers the side portion of the laser module 20. A dust-proof cavity 717 and an avoidance port communicating with the dust-proof cavity 717 are provided in the extension portion 716.

[0187] In this embodiment, the dust-proof seat 712 includes a main body covering the side portion of the base 711 and an extension portion 716 protruding from the top of the base 711. The circuit board 72 covers the surface of the dust-proof portion 361 facing away from the base 711, and part of the circuit board 72 is covered on the extension portion 716. A dust-proof cavity 717 and an avoidance port communicating with the dust-proof cavity 717 are provided in the extension portion 716.

[0188] Optionally, the dust-proof cavity 717 and the second accommodation space 7132 can communicate with each other; optionally, the avoidance opening and the first opening can be set as an integrated opening or two independent openings.

With such a setting, that is, a plugging hole 715 is opened on the top wall of the accommodation cavity 713 to avoid the thimble 73, so that the thimble 73 can be inserted into the plugging hole 715 at least when rising, thus there is no need to set the height of the accommodation cavity 713 to match the thimble 73, reducing the volume of the ranging module 70; and the setting of the plugging hole 715 can also play a guiding and limiting role for the thimble 73, avoiding the thimble 73 from being limited during the rising process.

[0196] Please refer to Figure 10 , in some embodiments of the present application, an adapter board 80 is provided in the accommodation cavity 11. The adapter board 80 can be a circuit board 72 or only a device with a conductive function. The conductive structure 17 is passed through the side wall of the housing 10 and electrically connected to the adapter board 80. The laser module 20 and other electronic devices in the accommodation cavity 11 can be electrically connected to the adapter board 80, and then power is supplied to each electronic device through the adapter board 80.

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

[0200] Please refer to Figure 4 , Figure 26 and Figure 27 , in some embodiments of the present application, the housing 10 of the laser 100 is provided with an installation port 13 communicating with the accommodation cavity 11. The laser 100 further includes an air inlet joint 90 communicating with the air guide channel 514. The air inlet joint 90 is provided at the installation port 13. When the laser 100 is disposed on the installation surface, the air inlet joint 90 is in communication with the air path interface 21b.

[0201] In this embodiment, an air nozzle module 50 is provided in the laser 100. The air nozzle module 50 covers the outside of the light exit 23 of the laser module 20 and is provided with a sequentially connected air guide channel 513, a diversion cavity 521, and an outlet 522. The light exit 23 is located in the diversion cavity 521, and the outlet 522 is coaxially arranged with the light exit 23, so that the laser can be emitted through the outlet 522. In addition, an installation port 13 is opened on the housing 10 of the laser 100, and an air inlet joint 90 is installed at the installation port 13. An air guide hose 55 is provided in the accommodation cavity 11. The air guide hose 55 can be bent and deformed according to requirements. The air 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 joint 90, and the other end of the air guide hose 55 is communicated with the air guide channel 513 of the air nozzle module 50.

[0202] On the device main body 200 of the laser device 1, a backplane 210 for installing the laser 100 is provided. One side plate surface of the backplane 210 is an installation surface for installing the laser 100. An air intake channel 21a is provided in the backplane 210, and an air path interface 21b communicating with the air intake channel 21a is opened on the installation surface of the backplane 210. Among them, the air intake channel 21a can penetrate through both side plate surfaces of the backplane 210, and the other end opening of the air intake channel 21a facing away from the installation surface can be used to connect to a gas supply structure 300 such as an air pump. When the laser 100 is installed on the installation surface of the backplane 210, the installation opening 13 opened on the side wall of the housing 10 of the laser 100 is arranged opposite to and communicated with the air path interface 21b on the installation surface, so that the laser 100 is communicated with the gas supply structure 300 such as an air pump through the air intake channel 21a. With such a setting, the operation of installing the laser 100 and connecting gas to the laser 100 is carried out simultaneously, and the air path is already connected when the laser 100 is installed, without the need to perform gas connection operations before or after installing the laser 100, improving the disassembly and assembly convenience of the laser 100.

[0203] During laser processing, a gas supply structure 300 such as an air pump drives air flow to flow into the air nozzle module 50 from the air intake channel 21a and the installation opening 13, and the air flow blows outwards from the outlet 522 through the diversion cavity 521. With such a setting, the dust and fumes outside the outlet 522 can be blown away, and the continuous air flow can also prevent impurities such as dust from entering the diversion cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to the window mirror or the focusing mirror, thereby avoiding affecting the laser emission.

[0204] Please refer to Figure 27 and Figure 28 , in some embodiments of the present application, a sealing ring 21d is clamped between the laser 100 and the backplane 210, and the sealing ring 21d is arranged to surround the circumference of the air path interface 21b.

[0205] In this embodiment, a sealing ring 21d is provided between the laser 100 and the backplane 210, and the sealing ring 21d is arranged to surround the circumference of the air path interface 21b. The sealing ring 21d can be made of elastic materials such as rubber, silica gel, and silicone rubber. Thus, when the laser 100 and the backplane 210 clamp the sealing ring 21d, the sealing ring 21d can undergo elastic deformation and respectively adhere tightly to the backplane 210 and the laser 100, so as to form a sealed cavity between the sealing ring 21d, the laser 100, and the backplane 210, improving the sealing performance between the installation opening 13 and the air path interface 21b and avoiding air leakage problems. Among them, the sealing ring 21d can be fixed on the backplane 210 or can also be fixed on the housing 10 of the laser 100, and no limitation is made here.

[0206] Please refer to Figure 28, in some embodiments of the present 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 arranged in the fixing groove 21f and protrudes from the mounting surface.

[0207] In this embodiment, the sealing ring 21d is fixed on the back plate 210 of the device main body 200. Thus, when other lasers 100 need to be replaced, it is not necessary to provide a sealing ring 21d on each laser 100, reducing the use of the sealing ring 21d. Among them, the mounting surface of the back plate 210 is recessed with a fixing groove 21f, so that the gas path interface 21b is opened on the bottom wall of the fixing groove 21f, and the sealing ring 21d is installed in the fixing groove 21f and arranged around the gas path interface 21b. Thus, the fixing groove 21f is used to limit the position of the sealing ring 21d, avoiding the sealing ring 21d being displaced and unable to surround the outer periphery of the gas path interface 21b and the mounting opening 13; in addition, part of the sealing ring 21d protrudes from the fixing groove 21f, so as to ensure that when the laser 100 is installed on the mounting surface, the laser 100 can be in contact with the sealing ring 21d, thus having good sealing performance.

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

[0209] In this embodiment, a locking member 21e is provided on the device main 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 magic tape, etc.; it can also be a screw or a detachable structure such as a pressing member used to press the outer ring 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 and being displaced.

[0210] Please refer to Figure 28 , in some embodiments of the present application, the locking member 21e includes a locking portion 211e and a pressing portion 212e connected to each other. The cross-sectional dimension of the pressing portion 212e is larger than that of the locking portion 211e. The locking member 21e is also provided with an air outlet hole 213e penetrating through the locking portion 211e and the pressing portion 212e; a contact portion 211d protrudes from the inner ring of the sealing ring 21d. The locking portion 211e passes through the sealing ring 21d and is inserted into the gas path interface 21b and fixedly connected to the back plate 210, and the pressing portion 212e presses the contact portion 211d against the back plate 210.

[0211] In this embodiment, the sealing ring 21d is pressed tightly against the backplane 210 by the locking member 21e.
