[0084] The present invention provides a laser 100.

[0085] Please refer to Figures 2 to 4, in some embodiments of the present application, the laser 100 includes a housing 10, a laser module 20, and a lifting module 30. Among them, a receiving cavity 11 is formed inside the housing 10, and the bottom of the receiving cavity 11 has an opening; at least part of the laser module 20 is disposed in the receiving cavity 11, and the laser module 20 is vertically movable relative to the housing 10, and the light-emitting port 23 of the laser module 20 is disposed downward facing the opening; the lifting module 30 is disposed in the receiving cavity 11 and is in transmission connection with the laser module 20 for driving the laser module 20 to move up and down.

[0086] The laser 100 proposed in the present application can be applied to laser processing equipment 1 such as laser marking machines, laser engraving machines, and laser cutting machines for emitting laser light. Among them, the laser 100 includes a housing 10 as a carrier and mounting base, a receiving cavity 11 is formed inside the housing 10, and an opening communicating with the receiving cavity 11 is provided at the bottom of the housing 10. At least part of the laser module 20 is disposed in the receiving cavity 11, and the laser module 20 is vertically movable relative to the housing 10; it can be that the laser module 20 is always located in the receiving cavity 11 and only moves up and down in the receiving cavity 11, and the light-emitting port 23 of the laser module 20 faces the opening at the bottom of the housing 10 to emit laser light outward; it can also be that the laser module 20 is vertically movable and enters and exits the receiving cavity 11 from the opening at the bottom of the housing 10, and 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.

[0087] 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 can be driven to move up and down by the lifting module 30.

[0088] Therefore, it can be understood that in the technical solution of the present application, the laser module 20 in the laser 100 can be driven by the lifting module 30 to move up and down in the housing 10 to adjust the height position of the laser focus. With such a setting, when the laser 100 is applied to the laser processing equipment 1, the laser 100 is fixed at the same height position through the housing 10, and the lifting module 30 in the laser 100 drives the laser module 20 or a part of the structure including the laser module 20 to move up and down to adjust the height position of the laser focus, so that it is not necessary to move the entire laser 100 up and down in the laser processing equipment 1, making the lifting process of adjusting the laser focus height more convenient.

[0089] With reference to Figures 3 to 6In some embodiments of the present application, a heat dissipation port 12 connected to the accommodating cavity is provided on the top of the housing 10. The laser 100 also includes a heat dissipation module 40. The heat dissipation module 40 includes a heat dissipation fan 41. The heat dissipation fan 41 is disposed in the accommodating cavity 11 and is located above the laser module 20. The air outlet of the heat dissipation fan 41 is arranged toward the laser module 20.

[0090] In this embodiment, the laser 100 further includes a heat dissipation module 40, which is disposed in the accommodating chamber 11 and is used to dissipate heat for the structure in the accommodating chamber 11. Specifically, the heat dissipation module 40 includes a heat dissipation fan 41, which is disposed on the top of the laser module 20 and has a heat dissipation port 12 on the bottom wall of the accommodating chamber 11. With such an arrangement, the heat dissipation fan 41 can drive the external airflow to flow into the accommodating chamber 11 and flow downward to dissipate heat for the structure in the accommodating chamber 11. In addition, the heat dissipation fan 41 is fixedly connected to the housing 10, and there is no need to make the heat dissipation fan 41 rise and fall with the laser module 20, making the process of controlling the rise and fall of the laser module 20 more convenient.

[0091] Combined with reference Figure 6 and Figure 10 In some embodiments of the present application, a mounting plate 14 is provided in the accommodating cavity 11, a vent 141 is provided in the mounting plate 14, a cooling fan 41 is provided on the upper surface of the mounting plate 14 and is arranged toward the vent 141, and the laser module 20 is provided below the mounting plate 14.

[0092] In this embodiment, a mounting plate 14 is arranged in the accommodating cavity 11, the mounting plate 14 is fixedly connected to the outer shell 10, and a vent 141 is opened on the mounting plate 14, a cooling fan 41 is fixed on the upper surface of the mounting plate 14, and an air outlet of the cooling fan 41 is arranged toward the vent 141; such an arrangement can prevent the cooling fan 41 from being suspended in the air and improve the stability of the cooling fan 41 fixed in the accommodating cavity 11; and the setting of the mounting plate 14 will not affect the cooling fan 41 from driving the airflow to dissipate heat for structures such as the laser module 20.

[0093] Please refer to Figure 7 In some embodiments of the present application, the heat dissipation module 40 also includes a first heat sink 42, which is connected to the side of the laser module 20, and a plurality of first heat dissipation fins 423 are provided on the side of the first heat sink 42 facing away from the laser module 20, and the plurality of first heat dissipation fins 423 are arranged side by side in the horizontal direction.

[0094] In this embodiment, the heat dissipation module 40 further includes a first radiator 42 disposed on the side wall of the laser module 20. The first radiator 42 includes a plurality of first heat dissipation fins 423 arranged side by side. The first radiator 42 can be made of a material with good heat conduction and heat dissipation performance, such as aluminum, aluminum alloy, copper or copper alloy, etc. The heat on the laser module 20 can be quickly transferred to the first radiator 42, and the plurality of first heat dissipation fins 423 on the first radiator 42 form a large heat dissipation area, so that the heat transferred to the first radiator 42 can be quickly dissipated.

[0095] Please refer to Figure 7 , in some embodiments of the present application, the plurality of first heat dissipation fins 423 are arranged in the horizontal direction. Such a setting is to make the first heat dissipation fins 423 extend substantially along the flow direction of the air flow driven by the heat dissipation fan 41, and an air flow path is formed between two adjacent first heat dissipation fins 423, so that when the air flow passes through the first radiator 42, it can pass through each air flow path to fully contact each first heat dissipation fin 423 and take away the heat on each first heat dissipation fin 423, thereby improving the heat dissipation efficiency of the first radiator 42. Moreover, arranging each first heat dissipation fin 423 in the horizontal direction also avoids the air flow being directly impacted on the surface of the first heat dissipation fin 423 and being blocked, which affects the normal flow of the air flow.

[0096] Please refer to Figure 6 , in some embodiments of the present application, the heat dissipation module 40 further includes a second radiator 43. The second radiator 43 is connected to the side of the laser module 20 facing away from the first radiator 42. A plurality of second heat dissipation fins 431 are provided on the side of the second radiator 43 facing away from the laser module 20. The plurality of second heat dissipation fins 431 are arranged side by side in the horizontal direction.

[0097] In this embodiment, the heat dissipation module 40 includes a first radiator 42 and a second radiator 43. The first radiator 42 and the second radiator 43 are respectively disposed on two opposite sides of the laser module 20, and both the first radiator 42 and the second radiator 43 are connected to the laser module 20 for absorbing the heat of the laser module 20 and accelerating the heat dissipation of the laser module 20. The structure of the first radiator 42 refers to the foregoing embodiment and will not be elaborated here. A plurality of second heat dissipation fins 431 are provided on the surface of the second radiator 43 facing away from the laser module 20. The plurality of second heat dissipation fins 431 increase the heat dissipation area, thereby increasing the contact area and heat exchange efficiency between the air flow and the second radiator 43, so that the heat transferred from the laser module 20 to the second radiator 43 can be quickly dissipated, improving the heat dissipation efficiency.

[0098] Please refer to Figure 6, in some embodiments of the present application, several second heat dissipation fins 431 are arranged in the horizontal direction. With such an arrangement, it is to make the second heat dissipation fins 431 extend substantially along the flowing direction of the air flow driven by the heat dissipation fan 41, and an air flow path is formed between two adjacent second heat dissipation fins 431, so that when the air flow passes through the second radiator 43, it can pass through each air flow path, fully contact each second heat dissipation fin 431 to take away the heat on each second heat dissipation fin 431, and improve the heat dissipation efficiency of the second radiator 43. Moreover, arranging each second heat dissipation fin 431 in the horizontal direction also avoids the air flow being directly impacted on the surface of the second heat dissipation fin 431 and being blocked, affecting the normal flow of the air flow.

[0099] Please refer to Figure 7 , in some embodiments of the present application, the lifting module 30 is connected to the first radiator 42 to drive the first radiator 42 to lift and drive the laser module 20 to lift.

[0100] In the embodiments of the present application, the first radiator 42 is fixed to one side surface of the laser module 20, and the lifting module 30 is connected to the first radiator 42 to drive the laser module 20 to lift by driving the first radiator 42 to lift. With such an arrangement, it can be avoided that the lifting module 30 is blocked by the first radiator 42 when being disassembled and assembled with the laser module 20, and the disassembly and assembly convenience is improved.

[0101] Please refer to Figure 7 , in some embodiments of the present application, one 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. A number of first heat dissipation fins 423 are provided in the heat dissipation area 421, and the lifting module 30 faces the avoidance area 422 and is connected to the avoidance area 422.

[0102] 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 avoidance area 422, and a number of first heat dissipation fins 423 arranged side by side are arranged in the heat dissipation area 421. With such an arrangement, 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, in the avoidance area 422, no first heat dissipation fins 423 can be completely provided, or some first heat dissipation fins 423 conforming to the outer surface of the lifting module 30 can be provided to improve the space utilization rate and the heat dissipation efficiency of the first radiator 42.

[0103] 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 disposed in the accommodation cavity 11 and extends along the lifting direction of the laser module 20. The first heat sink 42 is slidably sleeved on the optical axis 15.

[0104] In this embodiment, an optical axis 15 extending along the height direction of the laser 100 is provided in the accommodation cavity 11, and the first heat sink 42 is sleeved on the optical axis 15. Thus, the optical axis 15 plays a guiding and limiting role in the lifting of the first heat sink 42 and the laser module 20, improving the stability of the lifting process of the first heat sink 42 and the laser module 20. Among them, only one optical axis 15 can be provided, or at least two optical axes 15 arranged side by side can be provided, so as to balance the force and form multiple limits, further improving the stability of the lifting process of the first heat sink 42 and the laser module 20.

[0105] With reference to Figure 6 and Figure 10 , in some embodiments of the present application, a sliding hole 424 extending along the lifting direction is formed in the first heat sink 42. A linear bearing 425 is provided in the sliding hole 424, and the optical axis 15 passes through the linear bearing 425.

[0106] In this embodiment, a sliding hole 424 extending along the height direction of the laser 100 is formed in the first heat sink 42, and a linear bearing 425 is installed in the sliding hole 424, so that the linear bearing 425 cooperates with the optical axis 15, thereby reducing the sliding friction between the first heat sink 42 and the optical axis 15 and improving the smoothness and stability of the lifting process of the first heat sink 42 and the laser module 20.

[0107] Please refer to Figure 7 , Figure 13 and Figure 14 , in some embodiments of the present application, the lifting module 30 includes a driving member 31 connected to the housing 10 and a lifting rod 32 connected to the laser module 20. The lifting rod 32 is drivingly connected to the driving member 31 and extends along the lifting direction of the laser module 30. The driving member 31 is used to drive the lifting rod 32 to lift.

[0108] In this embodiment, the lifting module 30 includes a driving member 31 and a lifting rod 32. Among them, the driving member 31 is in transmission connection with the lifting rod 32. The driving member 31 and the lifting rod 32 can be respectively the pump body and the piston rod in a cylinder or a hydraulic cylinder. The driving member 31 and the lifting rod 32 can also form a motor screw assembly, or a motor and a rack or a worm, and are in transmission connection through a gear or a turbine, all of which can form a driving structure for driving the lifting rod 32 to lift by the driving member 31. 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 lift and lower.

[0109] 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 with the lifting and lowering of the lifting rod 32.

[0110] In this embodiment, a lower dust cover 33 is sleeved outside 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 is arranged as a corrugated sleeve in the following embodiment, both of which can make the lower dust cover 33 contract and expand with the lifting and lowering of the lifting rod 32. 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 a first end and a 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.

[0111] Please refer to Figure 13 , in some embodiments of the present application, at least part of the lower dust cover 33 is corrugated.

[0112] In this embodiment, at least a 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 whole of the lower dust cover 33 can be arranged as a retractable corrugated structure. In this way, the length change range of the lower dust cover 33 is the largest and it has a wide application range. It is also possible to arrange a part of the structure of the lower dust cover 33 as a retractable 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 segment, so as to prevent the lower dust cover 33 from being punctured by the lifting rod 32 due to excessive contraction and avoid affecting the dust-proof effect.

[0113] Please refer to Figure 13 and Figure 14 , in some embodiments of the present application, the lifting module 30 further includes a fixing seat 34. The fixing seat 34 is connected to the housing 10. The fixing seat 34 is provided with a through hole 341. The driving member 31 is arranged on the fixing seat 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.

[0114] In this embodiment, the lifting module 30 further includes a fixing seat 34. The fixing seat 34 is used to fix the lifting module 30 at the position to be installed on the device. For example, when the lifting module 30 is applied to the laser 100, the fixing seat 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 seat 34, and the lifting rod 32 passes through the through hole 341 on the fixing seat 34. The lower dust cover 33 can then be telescoped between the fixing seat 34 and the bottom end of the lifting rod 32. Among them, the lower dust cover 33 can be connected to the fixing seat 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 seat 34 can improve the installation stability of the lifting module 30 and facilitate the fixing of the lifting module 30 at the position to be installed, without specially setting a support structure in the device for fixing the lifting module 30.

[0115] With reference to Figure 13 and Figure 14 , in some embodiments of the present application, the first end of the lower dust cover 33 is provided with a clamping portion 331. The lower dust cover 33 passes through the through hole 341, and the clamping portion 331 is clamped between the fixing seat 34 and the driving member 31.

[0116] In this embodiment, a clamping portion 331 is provided at one end of the lower dust cover 33 close to the driving member 31, and the lower dust cover 33 is inserted through the through hole 341 of the fixed seat 34, so that the clamping portion 331 is located between the fixed seat 34 and the driving member 31 and is clamped and fixed by the fixed seat 34 and the driving member 31, thereby improving the connection strength and position stability of one end of the lower dust cover 33 close to the driving member 31 and preventing the end of the lower dust cover 33 close to the driving member 31 from loosening and falling off. Among them, the clamping portion 331 can be provided only at one circumferential position of the lower dust cover 33. In some embodiments, the connecting portion 331 can be a sheet-like structure arranged circumferentially or two or more connecting ears distributed circumferentially.

[0117] Please refer to Figure 7 , in some embodiments of the present application, the lifting module 30 further includes a protective pad 35. 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.

[0118] In this embodiment, a protective pad 35 is also provided in the lifting module 30. The protective pad 35 can be made of, but not limited to, vacuum plates, glass wool, expanded perlite, glass fiber felts, and materials such as polystyrene foam boards, so that the protective pad 35 can have 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, with the lower dust cover 33 located above the protective pad 35 and 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 the laser processing device 1, the lower dust cover 33 can be isolated from the processing position and the laser by the protective pad 35, preventing the laser or heat generated during processing from being transmitted to the lower dust cover 33, thereby avoiding 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.

[0119] In some embodiments, the cross-sectional profile of the position on the lifting rod 32 for sleeving the protective pad 35 can be 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.

[0120] 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 an installation hole 311 penetrating along the length direction of the lead screw, and the lead screw is inserted into the installation hole 311 and can extend upward and downward along the two open ends of the installation hole 311.

[0121] In this embodiment, the lifting module 30 is a through-type lead screw motor module. Among them, 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 that penetrates along the length direction of the lead screw. The lead screw is inserted into the mounting hole 311 and can extend outward from both 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. By using a through-type lead screw motor module as the lifting module 30, the space occupied by the lifting module 30 is relatively small, 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 using this lifting module 30.

[0122] 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.

[0123] In the foregoing embodiment, a 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 facing 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 stains from adhering to the part of the lead screw protruding above the motor, and preventing dust and oil stains and other impurities from entering the motor from the upper opening of the mounting hole 311, thereby avoiding 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 smoothly and stably without being blocked by impurities during the operation of the lifting module 30.

[0124] Please refer to Figure 13 and Figure 14 , in some embodiments of the present application, the upper dust cover 36 includes a dust-proof part 361 and a support part 362. The support part 362 covers the motor, the dust-proof part 361 is connected to one end of the support part 362 away from the motor and extends along the axial direction of the lifting rod 32. The radial dimension of the support part 362 is larger than the radial dimension of the dust-proof part 361, and an activity space is provided in the dust-proof part 361.

[0125] 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, forming an activity space with an opening at the lower side. The radial dimension of the support portion 362 is larger than that of the dust-proof portion 361. With such a setting, the contact area with the motor is increased by the support portion 362, and the connection strength between the upper dust cover 36 and the motor can be improved.

[0126] Please refer to Figure 8 and Figure 9 , in some embodiments of the present application, the laser 100 further includes a gas nozzle module 50. The gas nozzle module 50 is disposed below the laser module 20 and has a gas guiding channel 513, a diversion cavity 521 and an outlet 522. The diversion cavity 521 is communicated with the gas guiding channel 522. The gas guiding 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 outlet 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 outlet 23.

[0127] It can be understood that during the laser processing, dust and fumes are usually generated. If dust adheres to the optical lens of the light outlet 23 of the laser module 20, it is likely to affect the laser emission; if dust and the like adhere to the position to be processed, it will also affect the laser processing process. In this embodiment, the gas nozzle module 50 is provided in the laser 100. The gas nozzle module 50 is disposed below the laser module 20. The gas nozzle module 50 is formed with a gas guiding channel 513, a diversion cavity 521 and an outlet 522 that are sequentially communicated. 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 gas 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 gas nozzle module 50, and makes the air flow provided by the gas supply structure 300 blow outwards through the gas guiding channel 513, the diversion cavity 521 and the outlet 522 in sequence; with such a setting, 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 gas 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 gas nozzle module 50 can always form an air flow at the front end of the gas nozzle 52 of the laser module 20 better, and can also make the air flow blow towards the position to be processed, avoiding the position to be processed from being contaminated with dust, playing a good dust-proof role and ensuring the processing effect.

[0128] In this embodiment, by providing an air guide channel 513 in the air nozzle module 50, it is not necessary to provide an air pipe extending to the light output position to communicate with the diversion cavity 521, which can play a role in hiding the air path. There will be no air pipe under the laser module 20, thereby 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 uniform.

[0129] It should be noted that in this embodiment, the air nozzle module 50 can be only arranged to cover the light output port 23 to form a diversion cavity 521, or can be a combined structure of an air guide member 51 and an air nozzle 52 as in the following embodiment. In addition, the air guide pipe 220 can be directly extended from an external air source to the accommodation cavity 11 to be connected to the air nozzle module 50, or as in the following embodiment, an installation port 13 is opened on the housing 10, an air inlet joint 90 installed in the installation port 13 is connected to an external air source, and an air guide hose 55 is arranged in the accommodation cavity 11 to connect the air inlet joint 90 and the air nozzle module 50.

[0130] Please refer to Figures 9 to 11 , in some embodiments of the present application, the air nozzle module 50 includes an air guide member 51, an air nozzle 52, and an air pipe joint 56. The air guide member 51 is arranged under the laser module 20. An air guide channel 513 is provided in the air guide member 51. An access port for communicating with an air source is opened at one end of the air guide channel 513 away from the light output port 23. One end of the air guide member 51 close to the light output port 23 is provided with a first chamber 514 that penetrates through both ends along the center line direction of the light output port 23. The first chamber 514 communicates with the air guide channel 513; the air nozzle 52 covers the side of the air guide member 51 facing away from the laser module 20. The air nozzle 52 is provided with a second chamber 523 and an outlet 522. The second chamber 523 communicates with the first chamber 514 to form a diversion cavity 521 in combination.

[0131] In this embodiment, the nozzle module 50 includes a gas guide member 51, a nozzle 52, and a tracheal connector 56. The nozzle 52 and the gas guide member 51 are both disposed below the laser module 20. Among them, the gas guide member 51 includes a connected gas guide portion 511 and a connecting portion 512. A gas guide channel 513 is formed in the gas guide portion 511. The connecting portion 512 is disposed at the position of the light exit 23 and is provided with a first chamber 514 for avoiding the light exit 23 of the laser module 20. The gas guide channel 513 and the first chamber 514 are communicated with each other through a gas guide port on the pore wall of the first chamber 514. The nozzle 52 is disposed on the side of the gas guide member 51 facing away from the laser module 20 and is connected to the connecting 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, and the second chamber 523 is communicated with the first chamber 514 to jointly form a diversion chamber 521. A connection port is provided at a position of the gas guide member 51 away from the diversion chamber 521, and the connection port is connected with a tracheal connector, so as to be convenient for 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 exit 23 or causing other influences on the laser processing process.

[0132] Please refer to Figure 12 , in some embodiments of the present application, the nozzle 52 and the gas guide member 51 are detachably connected. Among them, the detachable connection method between the nozzle 52 and the gas guide member 51 can be at least one of screw connection, bolt connection, magnetic attraction connection, snap connection, etc. With such a setting, the first chamber 514, the second chamber 523, etc. can be directly cleaned and maintained by removing the nozzle 52. In addition, in some embodiments, optical elements such as a focusing lens are provided in the light exit structure, and the focusing lens can also be maintained or replaced by removing the nozzle 52, improving the use convenience.

[0133] Please refer to Figure 12 , in some embodiments of the present application, the nozzle 52 and the gas guide member 51 are magnetically attracted and connected.

[0134] In this embodiment, the nozzle 52 and the gas guide member 51 are detachably connected by a magnetic attraction connection method. Among them, a magnet 53 can be provided on the nozzle 52, and a magnet 53 or a magnetic conductive member 54 capable of adsorbing the magnet 53 can be provided on the gas guide member 51; it can also be that a magnet 53 is provided on the gas guide member 51 and a magnetic conductive member 54 is provided on the nozzle 52. With such a setting, when installing the nozzle 52, only the nozzle 52 needs to be close to the gas guide member 51 to be adsorbed on the gas guide member 51; when removing the nozzle 52, only force is needed to directly remove the nozzle 52, and the disassembly and assembly of the nozzle 52 are relatively simple.

[0135] Please refer to Figure 12, in some embodiments of the present application, one of the air guiding member 51 and the air nozzle 52 is provided with a magnet 53, and the other one of the air guiding member 51 and the air nozzle 52 is provided with a magnetic member 54. The magnetic member 54 is arranged to surround the circumferential direction of the diversion cavity 521 and is magnetically coupled with the magnet 53.

[0136] In this embodiment, the magnetic member 54 can be fixed on the surface of the air guiding member 51 facing the air nozzle 52, and correspondingly, the magnet 53 is arranged on the surface of the air nozzle 52 facing the air guiding member 51; alternatively, the magnet 53 can be arranged on the surface of the air guiding member 51 facing the air nozzle 52, and correspondingly, the magnetic member 54 is arranged on the surface of the air nozzle 52 facing the air guiding member 51. The magnetic member 54 can be set as a metal member that can be attracted by the magnet 53, such as being made of materials such as iron, cobalt, nickel, etc. The magnetic member 54 can also be set as a magnet, and the magnetic poles of the magnet arranged on the air guiding member 51 and the magnet arranged on the air nozzle 52 are oppositely arranged to generate magnetic attraction force with each other. Moreover, the magnetic member 54 is arranged to surround the circumferential direction of the diversion cavity 521, and the magnet 53 can also be arranged to surround the circumferential direction of the diversion cavity 521, or at least two magnets 53 are arranged at intervals along the circumferential direction of the diversion cavity 521, so that the air nozzle 52 can be detachably connected to the air guiding member 51 through the magnetic coupling between the magnet 53 and the magnetic member 54, and the air nozzle 52 is uniformly stressed along the circumferential direction of the diversion cavity 521, improving the installation stability.

[0137] Please refer to Figure 11 and Figure 12 , in some embodiments of the present application, a limiting step 515 is formed on the surface of the air guiding member 51 facing the air nozzle 52. The first chamber 514 is opened in the limiting step 515, and part of the air nozzle 52 is embedded in the limiting step 515.

[0138] In this embodiment, the limiting step 515 is recessed on the surface of the air guiding member 51 facing the air nozzle 52, and at least part 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, improving the installation convenience; but also can prevent the air nozzle 52 from shifting on the surface of the air guiding member 51, ensuring that the light outlet 23 of the laser module 20 is oppositely arranged with the outlet 522 of the air nozzle 52, so as to ensure that the laser can be emitted from the outlet 522 of the air nozzle 52.

[0139] Please refer to Figure 12 , in some embodiments of the present application, the air nozzle module 50 further includes a sealing gasket 57. The sealing gasket 57 is clamped between the air nozzle 52 and the air guiding member 51 and is arranged to surround the diversion cavity 521.

[0140] In this embodiment, a gasket 57 is provided between the air guiding member 51 and the air nozzle 52. The gasket 57 is arranged around the diversion cavity 521. And the gasket 57 usually has elasticity and can be elastically deformed by the extrusion of the air guiding member 51 and the air nozzle 52 to closely adhere to the air guiding member 51 and the air nozzle 52, improving the airtightness and preventing gas from leaking between the air nozzle 52 and the air guiding member 51.

[0141] 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 diversion cavity 521. One end of the lens barrel 22 facing the outlet 522 forms a light outlet 23, and the air guiding port for allowing air to enter the diversion cavity 521 is arranged opposite to the side wall of the lens barrel 22. With such an arrangement, the outer side wall of the lens barrel 22 can be used to guide the air flow, so that the air flow 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 air flow flows downward and is blown out from the outlet 522.

[0142] In an embodiment of the present application, a window lens is provided at the light outlet 23. With such an arrangement, it can prevent dust, smoke, the air flow of the air nozzle module 50, etc. from entering the laser module 20 through the light outlet 23.

[0143] 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. 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 is arranged in the laser generator 21. Or 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.

[0144] 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. With such an arrangement, the weight of the air guiding member 51 can be reduced, making the lifting process of the laser module 20 relatively light.

[0145] Please refer to Figure 9 and Figure 10 , in some embodiments of the present application, the housing 10 is provided with an installation port 13. The laser 100 further includes an air inlet joint 90 and an air guiding hose 55. The air inlet joint 90 is arranged in the accommodation cavity 11 and at the installation port 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 installation port 13, and the other end of the air guiding hose 55 is communicated with the air nozzle module 50. Wherein, the air guiding hose 55 deforms adaptively with the lifting of the laser module 20.

[0146] In the embodiment of the present application, components such as the laser module 20 in the laser 100 can be lifted and lowered, while the housing 10 and part of the structure are maintained fixed, so that the process of adjusting the height of the laser focus can be relatively easy. In this embodiment, an installation port 13 is opened on the housing 10, an air inlet joint 90 is installed at the position of the installation port 13, and an air guide hose 55 is arranged 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 nozzle module 50, and the length of the air guide hose 55 is greater than the straight-line distance between the air nozzle module 50 and the air inlet joint 90, and there is a part of the air guide hose 55 bent; thus arranged, when the air nozzle module 50 moves up and down with the laser module 20, the air guide hose 55 can generate adaptive deformation to follow the movement of the air nozzle module 50, maintain the connection with the air nozzle module 50, make the air flow relatively stable, and ensure the air blowing and dust removal effect.

[0147] In this embodiment, the external air source is connected to the air inlet joint 90 fixed on the housing 10, and the housing 10 does not move up and down in the laser processing device 1, so as to avoid the connection structure between the external air source and the laser 100 being pulled as the laser module 20 and the air nozzle module 50 move up and down when adjusting the height of the laser module 20 and the air nozzle module 50, and 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 of the lifting process of the laser module 20.

[0148] Please refer to Figure 9 and Figure 12 , in some embodiments of the present application, the air guide hose 55 is located on the side of the laser module 20. The tracheal 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 guide hose 55.

[0149] In this embodiment, the tracheal joint 56 includes a first joint 561 inserted into the access port of the air guide member 51, and a second joint 562 communicated with the first joint 561. The second joint 562 extends upward along the lifting direction of the laser module 20, so that when the air guide hose 55 is connected to the tracheal joint 56, the air guide hose 55 extends along the height direction, and the bending and deformation direction of the air guide hose 55 is the same as the lifting direction of the laser module 20 and the air nozzle module 50, thus avoiding interference of the air guide hose 55 on the lifting of the laser module 20 and making the air flow relatively stable.

[0150] Please refer to Figure 6, in some embodiments of the present application, the laser 100 further includes a position detection module 60 disposed in the accommodation cavity 11 for detecting the position of the laser module 20.

[0151] In the embodiments of the present application, the laser module 20 is arranged to be vertically movable relative to the housing 10, so that the height of the light exit 23 of the laser module 20 can be adjusted according to the height of different processing positions, thereby improving the processing accuracy and 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 provided in the laser 100 for detecting 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 the height adjustment 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., which is not limited herein.

[0152] 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 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 sensing member 635. The movable member 631 is movably disposed through the first through hole 614 and has a first position and a second position. Both the first trigger member 633 and the first sensing member 635 are located in the mounting cavity 613. One of the first trigger member 633 and the first sensing member 635 is disposed on the movable member 631, and the other of the first trigger member 633 and the first sensing 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 sensing member 635. The first reset member 65 is disposed in the mounting cavity 613 and acts on the movable member 631 so that the movable member 631 can have a tendency to stay in the second position.

[0153] Specifically, the mounting shell 61 serves as the mounting base of the position detection module 60, and an installation cavity 613 is formed therein. The outer contour of the mounting shell 61 can be a cuboid, a cube, a cylinder, a 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 mounting shell 61 can include an upper shell 611 and a lower shell 612 that are mutually covered, 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 a first through hole 614 opened on the mounting shell 61 and extends outside the installation cavity 613. The movable member 631 can slide relative to the mounting shell 61 along the central axis direction of the first through hole 614 and has a first position and a second position. In addition, a first reset member 65 is provided between the movable member 631 and the mounting shell 61. 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 the top wall side opposite to the first through hole 614 and apply an elastic thrust force 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 remain in 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 remain in 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 mounting 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 remain in 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 remain in the second position. When the movable member 631 is forced to move into the installation cavity 613, 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.

[0154] The induction module 63 further includes a first trigger 633 and a first inductor 635 disposed in the installation cavity 613. The first inductor 635 can be connected to the installation shell 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 inductor 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 will trigger the first inductor 635 to make the first inductor 635 emit an induction signal. In the embodiment of the present application, the first trigger 633 can also be connected to the installation shell 61, and the first inductor 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 inductor 635 to make the first inductor 635 emit an induction signal.

[0155] Among them, the first inductor 635 can be set as a Hall sensor, an optoelectronic switch, a proximity switch, a grating reader head, etc. For example, the first inductor 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 inductor 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 inductor 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 will not be elaborated here.

[0156] 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 housing 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 feedback the sensing signal 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 housing 61, dust and oil in the outside world will not affect this part of the structure, so that the performance of the position detection module 60 can be ensured to be stable, and thus it can be ensured 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.

[0157] 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 dust, oil and other sundries in the outside world, so that the risk of problems such as poor detection or false triggering can be reduced, and the performance stability and detection accuracy of the position detection module 60 can be ensured.

[0158] 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. When the movable member 131 is in the second position, the elastic member is in a compressed state.

[0159] 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. When the movable member 631 is in the second position, the elastic member is in a compressed state 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.

[0160] In some embodiments, 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. When the movable member 631 is in the second position, the elastic member is in a stretched state and applies an elastic tension 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.

[0161] 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; during the process that the movable member 631 is moved into the installation cavity 613 by an external force to reach the first position, the elastic member is elastically deformed under the force and generates an elastic force opposite to the direction of the external force. When the external force applied to the movable member 631 is withdrawn, the elastic member will restore its shape and move the movable member 631 to the second position.

[0162] Please refer to Figure 16 and Figure 17 , in some embodiments of the present application, the mounting shell 61 has a top wall disposed opposite to the first through hole 614. A limiting post 6315 is provided at one end of the movable member 631 facing the top wall, and the elastic member is sleeved on the limiting post 6315.

[0163] In this embodiment, the mounting shell 61 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.

[0164] Meanwhile, 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, so as to ensure the overall structural stability and performance stability of the position sensor.

[0165] Please refer to Figure 16 and Figure 17 , in some embodiments of the present application, a limiting hole 6317 is opened 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.

[0166] In this embodiment, the limiting post 6315 can be integrally formed with the movable member 631. With this arrangement, the connection strength between the limiting post 6315 and the movable member 631 is relatively high, and the relative position between the limiting post 6315 and the movable member 631 is relatively stable, improving the overall structural stability. In some embodiments, the limiting post 6315 can also be detachably connected to the movable member 631. When the limiting post 6315 is detachably connected to the movable member 631, a limiting hole 6317 can be formed at one end of the movable member 631 facing away from the first through hole 614, and a part of the limiting post 6315 can be inserted into the limiting hole 6317, thereby also improving the connection strength between the limiting post 6315 and the movable member 631, making it difficult for the limiting post 6315 to disengage from the movable member 631, 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 limiting hole 6317 to further limit the elastic member. Of course, a counterbore 6319 can also be formed on the end face of the movable member 631, and a limiting hole 6317 can be formed 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 limiting post 6315 passes through the counterbore 6319 and is inserted into the limiting hole 6317.

[0167] In addition, in some embodiments, the limiting 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, improving the connection strength between the limiting post 6315 and the movable member 631 and ensuring the relative position stability between the limiting post 6315 and the movable member 631 can avoid the problem that the movement of the movable member 631 is interfered by the limiting post 6315 due to the deviation of the limiting post 6315.

[0168] 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 both ends of the movable member 631 are respectively movably inserted into the second through hole 615 and the first through hole 614.

[0169] In this embodiment, a second through hole 615 opposite to the first through hole 614 may be formed in the mounting shell 61. For example, the second through hole 615 is formed 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 formed 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.

[0170] Among them, as in the above embodiment, a limiting post 6315 may protrude from one end of the movable member 631 facing the top wall, the second through hole 615 is formed in the top wall opposite to the first through hole 614, and the limiting post 6315 is inserted into the second through hole 615.

[0171] 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 plug-in portion 6313 which are connected. The plug-in portion 6313 passes through the first through hole 614, the stop portion 6311 is located in the mounting cavity 613, when the first trigger member 633 is in the second position, the stop portion 6311 abuts against the cavity wall where the first through hole 614 is formed, the first trigger member 633 or the first sensing member 635 is arranged on the stop portion 6311, and the first reset member 65 is connected between the stop portion 6311 and the mounting shell 61.

[0172] In this embodiment, the movable member 631 includes a stop portion 6311 and a plug-in 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 plug-in portion 6313 and the first through hole 614 in this direction; with such a setting, the plug-in 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 where the first through hole 614 is formed, 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 arranged 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.

[0173] 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.

[0174] 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 enclosed 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 enclosing 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 prevent 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.

[0175] 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 is in the first position, the first triggering member 633 is located between the transmitting portion 6351 and the receiving portion 6353, so that the first triggering member 633 blocks the signal path between the transmitting portion 6351 and the receiving portion 6353.

[0176] 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 move in and out between the transmitting portion 6351 and the receiving portion 6353 when the movable member 631 moves between the first position and the second position, so as to block the signal path between the transmitting portion 6351 and the receiving portion 6353 and prevent 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 an induction signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0177] Alternatively, it can be set that the receiving part 6353 cannot receive the signal sent by the transmitting part 6351 as the normal state. 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; the state where the receiving part 6353 can normally receive the signal sent by the transmitting part 6351 is set as the trigger state. 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 configured, 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.

[0178] Among them, the first sensing part 635 can be an optoelectronic switch. The transmitting part 6351 can emit an optical signal to the receiving part 6353. For example, the state where the receiving part 6353 can receive the optical signal is set as the normal state, and the state where the receiving part 6353 cannot receive the optical signal sent by the transmitting part 6351 is set as the trigger state; 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.

[0179] 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. The state where 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, can be set as the normal state, and the state where 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 Hall sensor cannot sense the magnetic field is set as the trigger state; when the magnetic field intensity sensed by the Hall sensor becomes weak or the Hall sensor cannot sense the magnetic field, 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.

[0180] 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.

[0181] 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.

[0182] In this embodiment, the first trigger member 633 may be connected to the movable member 631 or integrally provided with the movable member 631. It can be understood that the first sensing member 635 is an electronic device and usually requires power supply and feedback of sensing signals. In some embodiments, the first sensing member 635 may be self-powered and feedback sensing signals in a wireless transmission manner. In some embodiments, the first sensing member 635 needs to be connected to a wire for receiving electrical energy and feedbacking sensing signals, or as in the following embodiment, the first sensing member 635 is arranged on the circuit board 67. Therefore, in this embodiment, the first sensing member 635 is fixed in the installation cavity 613, and the first trigger member 633 is arranged on the movable member 631 to move with the movable member 631; with such an arrangement, it is avoided that the movement of the first sensing member 635 causes the wire connected to the first sensing member 635 to be pulled, thereby reducing the risk of wire breakage or damage, improving the stability of the electrical connection of the first sensing member 635, and ensuring the stable performance of the position detection module 60.

[0183] 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. The first sensing member 635 is arranged on the circuit board 67 and electrically connected to the circuit board 67. The first trigger member 633 is arranged on the movable member 631.

[0184] In this embodiment, the position detection module 60 further includes a circuit board 67 arranged in the installation cavity 613. The first sensing member 635 is arranged on the circuit board 67 and electrically connected to the circuit board 67. The circuit board 67 can be used to supply electrical energy to the first sensing member 635 and can also be used to process and forward the sensing signals generated by the first sensing member 635; among them, a power supply can be arranged on the circuit board 67 to provide the electrical energy required for the circuit board 67 and the first sensing member 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.; or the sensing signals can be transmitted by means of wired communication, which is not limited herein.

[0185] Please refer to Figure 15 and Figure 17 , in some embodiments of the present application, the installation shell 61 is provided with a connection port 617 communicating with the installation cavity 613. A connection seat 671 is arranged on the circuit board 67, and the connection seat 671 faces the connection port 617.

[0186] In this embodiment, a connection port 617 communicating with the installation cavity 613 is formed on the installation shell 61, and a connection seat 671 for plugging in a power line and a signal line is arranged on the circuit board 67. The power line and the signal line can be integrated into the same wire. With such an arrangement, the wire or the plug 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 perform signal transmission with the circuit board 67.

[0187] Please refer to Figure 19 , in some embodiments of the present application, the laser 100 further includes a ranging module 70. The ranging module 70 is arranged 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.

[0188] In the embodiment of the present application, the laser module 20 is made 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 arranged in the laser 100, and the ranging module 70 can be used to detect the distance between the focus 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 laser 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.

[0189] 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 arranged in the housing 71; the circuit board 72 covers the first opening; the thimble 73 extends downward through the bottom wall of the accommodation cavity 713 from the accommodation cavity 713, and the thimble 73 is liftably arranged 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 arranged in the accommodation cavity 713. The detection mechanism 74 includes a second trigger 741 and a second sensor 742. The second trigger 741 is connected to the thimble 73, and the second sensor 742 is arranged 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 741 triggers the second sensor 742.

[0190] In this embodiment, the distance measuring module 70 is located on the side of the laser module 20 and is arranged near 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 measuring module 70 is composed of a housing 71, a circuit board 72, a thimble 73 and a detection mechanism 74. The housing 71 and the circuit board 72 enclose a sealed accommodation cavity 713. A wiring base 721 can be arranged on the surface of the circuit board 72 exposed in the accommodation 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 one end of the thimble 73 penetrates out of the bottom of the accommodation cavity 713, so that the thimble 73 can be lifted and lowered and has a starting position and a trigger position above the starting position. The detection mechanism 74 is arranged in the accommodation cavity 11. The second trigger 741 of the detection mechanism 74 is connected to the thimble 73, and the second sensor 742 of the detection mechanism 74 is arranged on the circuit board 72 and electrically connected to the circuit board 72; thus, the detection mechanism 74 is prevented from being contaminated by soot and oil during the processing. The second trigger 741 of the detection mechanism 74 is connected to the part of the thimble 73 inserted into the accommodation cavity 713, so as to switch between the starting position and the trigger position as the thimble 73 is lifted and lowered. 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 75 in the following embodiment. When distance measurement is required, the laser module 20 is controlled to descend so that the distance measuring module 70 descends accordingly. After the thimble 73 abuts against the processing position to be processed, the laser module 20 and the distance measuring module 70 are continuously lowered so that the thimble 73 retracts into the accommodation cavity 713 until it rises to the trigger position. The second trigger 741 triggers the second sensor 742, and after the second sensor 742 generates an induction signal, it can be transmitted to the control system through the circuit board 72. At this time, by obtaining the descending distance of the laser module 20, the distance between the focus or the light exit of the laser module 20 and the processing position to be processed can be calculated. Among them, the descending distance of 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 lift and lower. After the second sensor 742 is triggered, 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 measuring 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.

[0191] Among them, the second sensing element 742 can be set as a Hall sensor, an optoelectronic switch, a proximity switch, a grating reading 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, such as 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 as to make the proximity switch send out an induction signal. If a grating reading 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 reading head move relative to each other. The grating reading 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 are not elaborated herein.

[0192] 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.

[0193] Please refer to Figure 22 , in some embodiments of the present application, the distance measuring module 70 further includes a second resetting member 75. The second resetting member 75 is arranged in the accommodating cavity 713 and acts between the housing 71 and the thimble 73, so that the thimble 73 has a tendency to stay at the starting position.

[0194] In this embodiment, a second reset member 75 is provided in the distance measuring module 70. The second reset member 75 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 side 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 remain 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 remain at the response position. The second reset member 75 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 remain 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 remain at the response position. When the ejector pin 73 moves into the installation cavity 613 under an external force, it will overcome the acting force applied by the second reset member 75. When the external force applied to the ejector pin 73 is withdrawn, the acting force applied by the second reset member 75 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 is stably held 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.

[0195] 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 trigger portion 7412. The fixing portion 7411 is sleeved on and fixed to the ejector pin 73, and the trigger 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 dust and other impurities from adhering to the electronic devices such as the circuit board 72, and avoid the heat generated during the processing from affecting the performance of the electronic devices.

[0196] Please refer to Figure 23, in some embodiments of the present application, the second trigger member 741 is provided with a threaded hole 7413, and at least a part of the outer surface of the ejector pin 73 is provided with an external thread, and the threaded hole 7413 is engaged with the external thread so that the trigger member 741 is threadedly connected to the ejector pin 73. 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 meet different processing requirements.

[0197] Please refer to Figures 21 to 23 , in some embodiments of the present application, the housing 71 includes a base 711 and a dust-proof seat 712. A first accommodation space 7131 is formed in the base 711, and a communication port 714 is provided on the side wall of the base 711 and communicates with the first accommodation space 7131. The dust-proof seat 712 covers the outer wall of the base 711 where the communication port 714 is located. A second accommodation space 7132 is formed in the dust-proof seat 712, and the second accommodation space 7132 communicates with the first accommodation space 7131 to form an accommodation cavity 713.

The circuit board 72 covers the avoidance port, and some components on the circuit board 72 are located on the surface of the circuit board 72 facing the dust-proof cavity 717.

[0199] 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 a part of the circuit board 72 is covered on the extension portion 716. The extension portion 716 is provided with a dust-proof cavity 717 and an avoidance port communicating with the dust-proof cavity 717. The avoidance port and the first opening are located on the same side. The circuit board 72 covers the avoidance port, so that some components provided on the circuit board 72 are arranged in the dust-proof cavity 717 to protect the components on the circuit board 72 and prevent the components from being contaminated by impurities such as dust and oil, which may affect the performance stability.

[0200] Optionally, the dust-proof cavity 717 and the second accommodation space 7131 can communicate with each other; optionally, the avoidance port and the first opening can be set as an integral opening or two independent openings.

[0201] In some embodiments, a first heat sink 42 or a second heat sink 43 is provided on the side of the laser module 20. At this time, the extension portion 716 can cover the surface of the first heat sink 42 or the second heat sink 43.

[0202] Please refer to Figure 19 and Figure 20 In some embodiments of the present application, one of a limiting groove 432 and a limiting protrusion 718 is provided on the surface of the extension portion 716 facing the laser module 20, and the other of the limiting groove 432 and the limiting protrusion 718 is provided on the side of the laser module 20.

With such a setting, that is, a plugging hole 715 is opened on the top wall of the accommodating cavity 713 for avoiding the ejector pin 73, so that the ejector pin 73 can be inserted into the plugging hole 715 at least when rising, thereby eliminating the need to set the height of the accommodating cavity 713 to match the ejector pin 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 ejector pin 73, avoiding the limiting of the ejector pin 73 during the rising process. In addition, it can be that the ejector pin 73 is inserted into the plugging hole 715 only when rising to a certain height, or it can be that the ejector pin 73 is always inserted into the plugging hole 715, which is not limited herein.

[0214] Please refer to Figure 4 、 Figure 26 and Figure 27 , in some embodiments of this application, the device main body 200 is provided with a back plate 210, and an air intake channel 21a is formed in the back plate 210. The air path interface 21b of the air intake channel 21a is located on the installation surface of the back plate 210. An air nozzle module 50 and an air intake joint 90 communicated with the air nozzle module 50 are arranged in the laser device 100. The air nozzle module 50 is used to blow air below the light output port 23. An installation opening 13 is formed in the housing 10 of the laser device 100, and the air intake joint 90 is arranged in the installation opening 13. When the laser device 100 is arranged on the installation surface, the air intake joint 90 and the air path interface 21b are mutually communicated.

[0215] 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 forms a diversion cavity 521, so that the light exit 23 is located in the diversion cavity 521. The air nozzle module 50 is provided with an outlet 522 communicating with the diversion cavity 521, and the outlet 522 of the diversion cavity 521 is disposed opposite to the light exit 23 of the laser module 20. In addition, an installation opening 13 is provided on the housing 10 of the laser 100. An air inlet joint 90 is installed at the position of the installation opening 13, and an air guide hose 55 is provided in the accommodation cavity 11.

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 communicates with the air nozzle module 50.

[0216] On the equipment main body 200 of the laser processing equipment 1, a back plate 210 for installing the laser 100 is provided. One side plate surface of the back plate 210 is an installation surface for installing the laser 100. An air inlet channel 21a is provided in the back plate 210, and an air path interface 21b communicating with the air inlet channel 21a is provided on the installation surface of the back plate 210.

[0217] 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 inlet channel 21a and the air inlet joint 90, and the air flow blows outwards from the outlet 522 through the diversion cavity 521. With such a setting, 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 exit 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting the laser emission.

[0218] 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 back plate 210, and the sealing ring 21d is arranged to surround the circumference of the air path structure.

[0219] In this embodiment, a sealing ring 21d is provided between the laser 100 and the backplane 210, and the sealing ring 21d is arranged circumferentially around the gas path interface 21b. The sealing ring 21d can be made of elastic materials such as rubber, silica gel, and silicone rubber. When the laser 100 and the backplane 210 clamp the sealing ring 21d, the sealing ring 21d can be elastically deformed to closely adhere to the backplane 210 and the laser 100 respectively, 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 mounting port 13 and the gas path interface 21b and avoiding air leakage problems. Among them, the sealing ring 21d can be fixed on the backplane 210 or on the housing 10 of the laser 100, which is not limited herein.

[0220] Please refer to Figure 28 , in some embodiments of the present application, the mounting surface is recessed with a fixing groove 21f, the mounting port 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.

[0221] In this embodiment, the sealing ring 21d is fixed on the backplane 210 of the device main body 200. When it is necessary to replace other lasers 100, 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 backplane 210 is recessed with a fixing groove 21f, 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, preventing the sealing ring 21d from being displaced and unable to surround the outer periphery of the gas path interface 21b and the mounting port 13. In addition, part of the sealing ring 21d protrudes from the fixing groove 21f, ensuring 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 better sealing performance.

[0222] Please refer to 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 backplane 210.

[0223] In this embodiment, a locking member 21e is provided on the device main body 200, and the locking member 21e acts between the backplane 210 and the sealing ring 21d to fix the sealing ring 21d to the backplane 210. The locking member 21e can be an adhesive structure, such as glue, double-sided tape, or Velcro, etc.; or it can be a screw or a pressing member used to press the outer or inner ring of the sealing ring 21d and other detachable structures. Using the locking member 21e to fix the sealing ring 21d can improve the connection strength between the sealing ring 21d and the backplane 210 and reduce the risk of the sealing ring 21d falling off and being displaced.

[0224] Please refer to Figure 28 In some embodiments of the present application, the locking member 21e includes a connected locking portion 211e and a crimping portion 212e. The cross-sectional dimension of the crimping portion 212e is larger than that of the locking portion 211e. The locking member 21e is further provided with an air vent 213e penetrating through the locking portion 211e and the crimping portion 212e.

[0225] The inner ring of the sealing ring 21d is convexly provided with an abutting portion 211d. The locking portion 211e is inserted through the sealing ring 21d and inserted into the gas path interface 21b to be fixedly connected to the back plate 210. The crimping portion 212e presses the abutting portion 211d against the back plate 210.

[0226] In this embodiment, the locking member 21e is used to press the sealing ring 21d tightly against the back plate 210. Specifically, the locking member 21e includes a connected locking portion 211e and a pressing portion. The locking portion 211e can be inserted through the sealing ring 21d and inserted into the gas path interface 21b and connected and fixed to the back plate 210. The crimping portion 212e is disposed outside the gas path interface 21b. An abutting portion 211d is provided on the inner ring of the sealing ring 21d. The abutting portion 211d can be disposed around the inner ring of the sealing ring 21d or can be disposed at a partial position on the inner ring. For example, at least two spaced abutting portions 211d are disposed along the inner ring. When the locking portion 211e of the locking member 21e is inserted into the gas path interface 21b, the crimping portion 212e of the locking member 21e presses against the abutting portion 211d of the sealing ring 21d, so that the sealing ring 21d can be tightly fixed on the back plate 210. At the same time, an air vent 213e penetrating through the locking portion 211e and the crimping portion 212e needs to be opened on the locking member 21e to avoid blocking the gas path interface 21b. The connection between the locking portion 211e of the locking member 21e and the gas path interface 21b can be an interference fit, or can be bonding or threaded connection, etc., which is not limited herein.

[0227] When the locking member 21e of this embodiment is used to fix the sealing ring 21d, the locking member 21e can be hidden inside the sealing ring 21d, so as to avoid the laser 100 being scratched by the locking member 21e or the laser 100 not being able to be closely attached to the sealing ring 21d when the laser 100 is fixed to the back plate 210.

[0228] Please refer to Figure 27 In some embodiments of the present application, the other end opening of the intake passage 21a away from the gas path interface 21b is opened on the top surface of the back plate 210.

[0229] In this embodiment, the end of the intake passage 21a for connecting the air supply structure 300 is opened on the top surface of the back plate 210. With this arrangement, the air pipe 220 connecting the air supply structure 300 and the intake passage 21a can be connected to the top of the back plate 210, which can not only be far away from the processing position and the laser, but also facilitate the connection of the air pipe 220.

[0230] Please refer to Figure 26 and Figure 29 , in some embodiments of the present application, the device body 200 is provided with a translation assembly 230. The translation assembly 230 can be used to drive the back plate 210 to drive the laser 100 to translate in one direction, or can also be used to drive the laser 100 to translate in different directions. For example, defining the X direction and the Y direction that are perpendicular to each other, the translation assembly 230 can be used to drive the back plate 210 and the laser 100 to translate in the X direction or the Y direction, or the translation assembly 230 can include the intersecting first slide rail 2301 and the second slide rail 2302. The second slide rail 2302 is slidably arranged on the first slide rail 2301. The back plate 210 and the laser 100 are arranged on the second slide rail 2302. The back plate 210 can translate in the X direction along the second slide rail 2302, and the second slide rail 2302 can also drive the back plate 210 and the laser 100 to translate in the Y direction along the first slide rail 2301.

[0231] The arrangement of the translation assembly 230 enables the laser 100 to move to different positions for processing. In addition, a first drag chain 240 and a second drag chain 250 are arranged in the device body 200. One end of the first drag chain 240 is fixed on the first slide rail 2301, and the other end is connected to the second slide rail 2302. The second drag chain 250 is arranged on the second slide rail 2302, and one end of the second drag chain 250 is connected to the second slide rail 2302, and the other end of the second drag chain 250 is connected to the back plate 210. The air pipe 220 connecting the air supply structure 300 and the intake passage 21a is passed through the first drag chain 240 and the second drag chain 250, so as to protect and limit the air pipe 220, avoid the air pipe 220 from being scattered and affecting the movement of the laser 100, and avoid the air pipe 220 from being damaged.

[0232] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
