[0058] This application proposes a laser device 1 .

[0059] Please refer to Figures 1 and 3 to 7. In some embodiments of the present application, the laser device 1 includes a device body 200 and a laser 100. The device body 200 is provided with a back plate 210, in which an air inlet channel is formed. The mounting surface of the back plate 210 is provided with an air path interface 21b connected to the air inlet channel; the laser 100 includes a housing 10, a laser module 20 and a nozzle module 50. The housing 10 is provided on the mounting surface, and a receiving cavity is formed in the housing 10. The bottom of the receiving cavity is open, at least part of the laser module 20 is provided in the receiving cavity, and the light outlet 23 of the laser module 20 faces the bottom of the housing 10; the housing 10 is provided with a mounting port 13, and the mounting port 13 and the air path interface 21b are arranged opposite to each other and are connected to each other. The nozzle module 50 is connected to the mounting port 13 to guide the airflow to blow in front of the light outlet 23.

[0060] The laser device 1 proposed in this application can be a laser engraving machine, a laser marking machine, a laser cutting machine, etc. The laser device 1 includes a device body 200 and a laser 100. The device body 200 of the laser device 1 is provided with a back plate 210 for mounting the laser 100. One side surface of the back plate 210 is a mounting surface, and the laser 100 is arranged on the mounting surface. Usually, in the laser device 1, the processing platform for placing the processing material is located below the laser 100, so that the light outlet 23 of the laser 100 is set downward. In this case, the mounting surface of the back plate 210 can be a vertical plane, so that the side wall of the laser 100 is fixed to the mounting surface; or the mounting surface of the back plate 210 can be set horizontally downward, so that the top wall of the laser 100 is fixed to the mounting surface. The connection method between the laser 100 and the back panel 210 can be to set a dovetail groove on the back panel 210 and set a corresponding plug-in structure on the shell 10 so that the shell 10 and the back panel 210 are plugged together. In addition, the connection method between the laser 100 and the back panel 210 can also be at least one of a snap connection, a bolt connection, a magnetic connection, etc., which is not limited here.

[0061] The laser 100 includes a housing 10, a laser module 20, and a nozzle module 50. The housing 10 serves as a support and mounting base. A housing cavity is formed within the housing 10, and an opening is provided at the bottom of the housing 10 to communicate with the cavity. At least a portion of the laser module 20 is disposed within the cavity, and the laser module 20's light outlet 23 opens toward the bottom of the housing 10 to emit laser light downward. The nozzle module 50 can be fixed to the housing 10, to the laser module 20, or to other structures within the laser 100, such as a heat sink module. Among them, the air nozzle module 50 can be provided with an air blowing head facing the front of the light outlet 23 of the laser module 20, or it can be a guide cavity 521 provided with a cover on the light outlet 23 as in the following embodiment, or an air flow inlet is opened on the side wall of the light outlet channel 221 of the laser module 20, and the air nozzle module 50 is connected to the air flow inlet, both of which can achieve the purpose of guiding the air flow to blow toward the front of the light outlet 23 for dust removal, and can blow away the dust and smoke in front of the light outlet 23 to prevent dust and other impurities from adhering to optical lenses 222 such as window mirrors or focusing mirrors, thereby avoiding affecting the laser emission; at the same time, the air flow can be blown toward the position to be processed to prevent the position to be processed from being contaminated by dust, thereby playing a better dust removal and dust prevention role, and ensuring the processing effect.

[0062] Furthermore, in the embodiment of the present application, an air inlet channel is provided in the back panel 210 of the device body 200, and an air path interface 21b communicating with the air inlet channel is provided on the mounting surface of the back panel 210. The air inlet channel can be provided through both sides of the back panel 210, or the other end of the air inlet channel away from the air path interface 21b can be provided on any side between the two sides. The other end of the air inlet channel away from the air path interface 21b can be used to connect to an air supply structure 300, such as an air pump. When the laser 100 is mounted on the mounting surface of the back panel 210, the mounting opening 13 provided on the side wall of the laser 100 housing 10 is disposed opposite and connected to the air path interface 21b on the mounting surface, thereby enabling the laser 100 to communicate with the air supply structure 300, such as an air pump, through the air inlet channel. With this arrangement, the laser 100 can be installed and the gas connection operation can be performed simultaneously. When the laser 100 is installed, the gas path is connected at the same time. There is no need to connect the gas before or after installing the laser 100, thereby improving the convenience of disassembly and assembly of the laser 100.

[0063] During laser processing, the air supply structure 300 such as an air pump drives air flow from the air inlet channel and the mounting port 13 into the air nozzle module 50 , and then blows the air toward the front of the air nozzle 52 of the laser module 20 for dust removal.

[0064] Therefore, it can be understood that the laser equipment 1 of the present application includes an equipment body 200 and a laser 100 installed on the equipment body 200. The laser 100 is provided with an air nozzle module 50, which can be connected to the air supply structure 300 to guide the airflow to the front of the light outlet 23 of the laser 100, thereby preventing dust and other debris from adhering to the optical lens 222 of the laser module 20 during the processing process; it can also blow away the dust on the processing position in front of the light outlet 23, thereby reducing the impact of dust on the laser processing process and ensuring the laser processing effect.

[0065] Furthermore, within the main body 200 of the laser device 1, an air inlet channel is formed within the back plate 210 for mounting the laser 100. The air inlet channel can communicate with the air supply structure 300, and an air path interface 21b connected to the air inlet channel is provided on the mounting surface of the back plate 210. Simultaneously, a mounting opening 13 connected to the air nozzle module 50 is provided on the housing 10 of the laser 100. When the laser 100 is mounted on the mounting surface of the back plate 210, the mounting opening 13 and the air path interface 21b are arranged opposite each other and communicate with each other. With this arrangement, the airflow driven by the air supply structure 300 can flow through the air inlet channel, the air path interface 21b, the mounting opening 13, and the air nozzle module 50 to blow toward the front of the light outlet 23 of the laser module 20. That is, the present application allows the installation of the laser 100 and the connection of gas to the laser 100 to be performed simultaneously. The gas path is already connected when the laser 100 is installed, and there is no need to perform the gas connection operation before or after the installation of the laser 100, thereby improving the convenience of disassembly and assembly of the laser 100.

[0066] Referring to FIG. 5 , in some embodiments of the present application, a sealing ring 21 d is sandwiched between the housing 10 and the back plate 210 , and the sealing ring 21 d is disposed around the circumference of the gas path interface.

[0067] In this embodiment, a sealing ring 21d is provided between the laser 100 and the back plate 210. The sealing ring 21d is disposed around the circumference of the gas path interface 21b. The sealing ring 21d can be made of an elastic material such as rubber, silicone, or silicone rubber. When the laser 100 and the back plate 210 clamp the sealing ring 21d, the sealing ring 21d can be elastically deformed and pressed against the back plate 210 and the laser 100, respectively. This allows the sealing ring 21d, the laser 100, and the back plate 210 to enclose a sealed cavity, thereby improving the sealing between the mounting port 13 and the gas path interface 21b and preventing air leakage.

[0068] The sealing ring 21d may be fixed on the back plate 210 or on the housing 10 of the laser 100, which is not limited here.

[0069] 5 , in some embodiments of the present application, a fixing groove 21 f is recessed on the mounting surface, the mounting opening 13 is opened on the bottom wall of the fixing groove 21 f , and a sealing ring 21 d is disposed in the fixing groove 21 f and protrudes from the mounting surface.

[0070] In this embodiment, the sealing ring 21d is fixed to the back plate 210 of the device body 200. Therefore, when other lasers 100 need to be replaced, it is not necessary to set the sealing ring 21d on each laser 100, thereby reducing the use of the sealing ring 21d. Among them, the mounting surface of the back plate 210 is concavely provided with a fixing groove 21f, so that the gas path interface 21b is opened on the bottom wall of the fixing groove 21f, and the sealing ring 21d is installed in the fixing groove 21f and arranged around the gas path interface 21b. The fixing groove 21f is used to limit the sealing ring 21d, thereby preventing the sealing ring 21d from being offset and unable to surround the gas path interface 21b and the outer periphery of the mounting opening 13. In addition, a portion of the sealing ring 21d protrudes from the fixing groove 21f, thereby ensuring that when the laser 100 is mounted on the mounting surface, the laser 100 can abut against the sealing ring 21d, thereby achieving better sealing performance.

[0071] Referring to FIG. 5 , in some embodiments of the present application, the device body 200 further includes a locking member 21 e , which fixes the sealing ring 21 d to the back plate 210 .

[0072] In this embodiment, a locking member 21e is provided on the device body 200. This locking member 21e acts between the back plate 210 and the sealing ring 21d to secure the sealing ring 21d to the back plate 210. The locking member 21e can be an adhesive structure, such as glue, double-sided tape, or Velcro; it can also be a removable structure, such as a screw or a pressing member configured to press against the outer or inner ring of the sealing ring 21d. Using the locking member 21e to secure the sealing ring 21d improves the connection strength between the sealing ring 21d and the back plate 210 and reduces the risk of the sealing ring 21d falling off or becoming misaligned.

[0073] 5 , in some embodiments of the present application, the locking member 21e is provided with an air outlet 213e with both ends extending therethrough. The locking member 21e is passed through the sealing ring 21d and connected to the back plate 210 , and the air outlet 213e is communicated with the air path interface 21b .

[0074] In this embodiment, the locking member 21e can be hidden inside the sealing ring 21d to prevent the laser 100 from contacting the locking member 21e when the laser 100 is fixed to the backplate 210, thereby preventing the laser 100 from being scratched by the locking member 21e or preventing the laser 100 from being firmly attached to the sealing ring 21d. Furthermore, the locking member 21e needs to have air outlet holes 213e extending through both ends to prevent blockage of the air path interface 21b. The locking member 21e and the air path interface 21b can be connected by an interference fit, adhesive bonding, or threaded connection, etc., without limitation herein.

[0075] Please refer to Figure 5. In some embodiments of the present application, the locking member 21e includes a locking portion 211e and a crimping portion 212e that are connected to each other. The crimping portion 212e is located at one end of the locking portion 211e. The cross-sectional size of the crimping portion 212e is larger than the cross-sectional size of the locking portion 211e. The air outlet 213e passes through the locking portion 211e and the crimping portion 212e; the locking portion 211e is inserted into the sealing ring 21d and inserted into the air path interface 21b and fixedly connected to the back plate 210. The crimping portion 212e presses the sealing ring 21d to fix the sealing ring 21d to the back plate 210.

[0076] In this embodiment, the locking member 21e is used to press the sealing ring 21d onto the back plate 210; specifically, the locking member 21e includes a locking portion 211e and a crimping portion 212e connected to each other, and the air outlet 213e passes through the locking portion 211e and the crimping portion 212e. The locking portion 211e is provided through the sealing ring 21d and inserted into the air path interface 21b, and is fixedly connected to the back plate 210; and the crimping portion 212e is provided on the outside of the air path interface 21b; An abutment portion 211d is provided on the inner ring, and the abutment portion 211d can be arranged around the inner ring of the sealing ring 21d, or can be arranged at a partial position of the inner ring, for example, at least two abutment portions 211d are arranged at intervals along the inner ring; when the locking portion 211e of the locking member 21e is inserted into the air path interface 21b, the crimping portion 212e of the locking member 21e is pressed onto the abutment portion 211d of the sealing ring 21d, so that the sealing ring 21d can be pressed and fixed on the back plate 210.

[0077] Referring to FIG. 4 , in some embodiments of the present application, the air inlet 117 of the air inlet channel 21 a is opened on the top surface of the back plate 210 .

[0078] In this embodiment, the air inlet 117 of the air inlet channel for connecting to the air supply structure 300 is opened on the top surface of the back plate 210. In this way, the air pipe 220 connecting the air supply structure 300 and the air inlet channel can be connected to the top of the back plate 210, which can be away from the processing position and the laser and facilitate the connection of the air pipe 220.

[0079] Please refer to Figure 4. In some embodiments of the present application, the device body 200 also includes an air intake connector 90. The air intake connector 90 is installed at the air inlet 117 of the air intake channel 21a and is connected to the air intake channel 21a. The air intake connector 90 is used to connect the air pipe 220.

[0080] In this embodiment, the air inlet connector 90 and the air inlet 117 can be plug-fitted or threaded; for example, a threaded connector is used as the air inlet connector 90. The air inlet connector 90 facilitates the connection between the air pipe 220 and the air inlet passage 21a.

[0081] Please refer to Figure 7. In some embodiments of the present application, the laser module 20 can be raised and lowered relative to the housing 10, and the air nozzle module 50 is arranged on the laser module 20; the laser 100 also includes an air guide hose 55, which connects the installation port 13 and the air nozzle module 50, and the air guide hose 55 adaptively deforms as the laser module 20 is raised and lowered.

[0082] In this embodiment, the laser module 20 in the laser 100 can be raised and lowered within the housing 10 by the lifting module to adjust the height of the laser focus. In the laser device 1, the laser 100 is fixed at a constant height by the housing 10. Only the lifting module in the laser 100 drives the laser module 20, or a portion thereof, to be raised and lowered to adjust the height of the laser focus. This eliminates the need to raise and lower the entire laser 100 within the laser device 1, making the raising and lowering process for adjusting the height of the laser focus much simpler.

[0083] In addition, in this embodiment, the air nozzle module 50 is fixed to the laser module 20, and an air hose 55 is disposed within the accommodating cavity. The air hose 55 can be bent and deformed as needed and can be made of plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), or other materials. One end of the air hose 55 is connected to the mounting port 13, and the other end of the air hose 55 is connected to the air nozzle module 50. The length of the air hose 55 is greater than the straight-line distance between the air nozzle module 50 and the mounting port 13, and the air hose 55 is partially bent. This arrangement allows the air nozzle module 50 to rise and fall with the laser module 20, and the air hose 55 can adaptively deform to follow the movement of the air nozzle module 50, maintaining its connection with the air nozzle module 50. This allows the air nozzle module 50 to consistently form a relatively stable airflow at the front end of the air nozzle 52 of the laser module 20, ensuring a good air blowing and dust removal effect.

[0084] 8 to 10 , in some embodiments of the present application, the air nozzle module 50 is covered outside the light outlet 23 , and the air nozzle module 50 is provided with a guide cavity 521 and an outlet 522 communicating with the guide cavity 521 .

[0085] In this embodiment, the air nozzle module 50 is covered on the outside of the light outlet 23 of the laser module 20 and forms a guide cavity 521. The light outlet 23 is located in the guide cavity 521, and the air nozzle module 50 is provided with an outlet 522 connected to the guide cavity 521. The outlet 522 of the guide cavity 521 is arranged opposite to the light outlet 23 of the laser module 20, so that the laser can be emitted through the outlet 522. During laser processing, the air supply structure 300 supplies air flow to the air nozzle module 50 via the air inlet channel, and the air flow is blown outward through the guide cavity 521 and the outlet 522. With such a configuration, an air flow flowing around the light outlet 23 can be formed in the guide cavity 521, thereby preventing dust and other impurities from entering the guide cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to optical lenses 222 such as window mirrors or focusing mirrors. When the air flow is blown out from the outlet 522, the dust and smoke outside the outlet 522 can also be blown away, thereby avoiding affecting the laser emission.

[0086] It should be noted that, in this embodiment, the air nozzle module 50 may be configured to simply cover the light outlet 23 and form a flow guide cavity 521 , or it may be configured as a combined structure of an air guide member 51 and an air nozzle 52 in the following embodiment.

[0087] Please refer to Figures 9 and 10. In some embodiments of the present application, the air nozzle module 50 includes an air guide part 51 and an air nozzle 52. The air guide part 51 is arranged below the laser module 20. An air guide channel 513 connected to the mounting port 13 is provided in the air guide part 51. The air guide channel 513 is connected to the mounting port 13. A first chamber 514 is provided at one end of the air guide part 51 close to the light outlet 23. The hole wall enclosing the first chamber 514 is provided with an air guide port connected to the air guide channel 513; the air nozzle 52 cover is arranged in the avoidance hole and encloses the avoidance hole to form a guide cavity 521, and the air nozzle 52 is opened. An outlet 522 is opened.

[0088] In this embodiment, the air nozzle module 50 includes an air guide part 51 and an air nozzle 52, and the air nozzle 52 and the air guide part 51 are both covered below the laser module 20, wherein the air guide part 51 includes an air guide portion 511 and a connecting portion 512 connected to each other, and an air guide channel 513 is formed in the air guide portion 511, and the connecting portion 512 is covered at the position of the light outlet 23, and is provided with an avoidance hole for avoiding the light outlet 23 of the laser module 20, and the air guide channel 513 and the avoidance hole are interconnected through the air guide port on the wall of the avoidance hole; the air nozzle 52 is covered on the avoidance hole and is interconnected with the connecting portion 512 of the air guide part 51, so that the air nozzle 52 and the air guide part 51 are arranged as one body, thereby improving the overall structural stability of the air nozzle module 50; of course, the air nozzle 52 and the air guide part 51 can also be detachably connected. With this arrangement, the gas source can be connected to the access port of the gas guide 51 away from the light outlet 23, which can prevent the gas pipe 220 connected to the gas source from directly extending to a position adjacent to the light outlet 23 of the laser module 20, thereby preventing the gas pipe 220 from blocking the light outlet 23 or causing other effects on the laser processing process.

[0089] Referring to Figures 8 and 9 , in some embodiments of the present application, an air pipe connector 56 is inserted into the end of the air guide channel 513 away from the diversion cavity 521. The end of the air pipe connector 56 connected to the air guide hose 55 extends upward along the direction of the laser module 20. This configuration allows the portion of the air guide hose 55 connected to the nozzle module 50 to extend along the direction of the laser module 20. This can reduce interference with the air guide hose 55 during the lifting and lowering of the laser module 20 and the nozzle module 50, and prevent the air guide hose 55 from bending at excessive angles, thereby ensuring a more stable airflow to the nozzle module 50.

[0090] Please refer to Figures 11 and 12. In some embodiments of the present application, the laser module 20 is provided with a light output channel 221, an optical lens 222 is provided in the light output channel 221, the light outlet 23 is located at one end of the light output channel 221, and an air flow inlet is provided on the side wall between the light output port 23 and the optical lens 222, and the air nozzle module 50 is connected to the air flow inlet.

[0091] In this embodiment, a light outlet channel 221 is provided in the laser module 20, and an optical lens 222 is provided in the light outlet channel 221. The optical lens 222 can be a focusing lens, which is used to reduce the laser spot size, increase the energy density of the laser spot, and improve the processing accuracy and processing efficiency. In addition, the optical lens 222 can also include a window lens provided on the side of the focusing lens facing the light outlet 23. The window lens can be used to protect the focusing lens and other structures to prevent dust and other debris from entering the laser module 20 along the light outlet channel 221. In this embodiment, the light outlet 23 of the light outlet channel 221 is spaced apart from the optical lens 222, and an air flow inlet is opened on the side wall of the light outlet channel 221 between the optical lens 222 and the light outlet 23. In this case, the air nozzle module 50 is an air pipe joint 56, which is connected to the air flow inlet to connect the air flow inlet and the mounting port 13. In this arrangement, when the air supply structure 300 supplies air to the laser 100 via the air inlet channel, the air flow can enter the light output channel 221 via the air nozzle module 50, and due to the arrangement of the optical lens 222, the air flow can only flow outward from the light output port 23, thereby blowing away dust and other debris in front of the light output port 23, and blowing away dust at the processing position, so as to improve the laser processing effect.

[0092] Please refer to Figures 1 to 3. In some embodiments of the present application, the device body 200 includes a translation assembly 230, the translation assembly 230 includes an intersecting first slide rail 2301 and a second slide rail 2302, the second slide rail 2302 is slidably disposed on the first slide rail 2301, and the back panel 210 is slidably disposed on the second slide rail 2302.

[0093] In this embodiment, a translation assembly 230 is provided within the device body 200, defining a first direction and a second direction perpendicular to each other. The translation assembly 230 includes a first slide rail 2301 and a second slide rail 2302 intersecting each other. The first slide rail 2301 extends along the first direction, and the second slide rail 2302 extends along the second direction. The second slide rail 2302 is slidably mounted on the first slide rail 2301, allowing the second slide rail 2302 to slide along the length of the first slide rail 2301. The back plate 210 is slidably mounted on the second slide rail 2302, allowing the back plate 132 to drive the laser 100 to slide along the length of the second slide rail 2302. The translation assembly 230 also includes a first drive member for driving the second slide rail 2302 to slide along the first slide rail 2301, and a second drive member for driving the back plate 210 to slide along the second slide rail 2302. The configuration of the translation assembly 230 enables the laser 100 to be moved to different positions for processing.

[0094] Please refer to Figures 1 to 3. In one embodiment of the present application, the device body 200 also includes a first drag chain 240 and a second drag chain 250. The first drag chain 240 is arranged on the first slide rail 2301, one end of the first drag chain 240 is connected to the first slide rail 2301, and the other end of the first drag chain 240 is connected to the second slide rail 2302; the second drag chain 250 is arranged on the second slide rail 2302, 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 panel 210; the laser device 1 also includes an air pipe 220, the air pipe 220 is passed through the first drag chain 240 and the second drag chain 250, one end of the air pipe 220 is connected to the air inlet 117 of the air inlet channel 21a, and the other end of the air pipe 220 is used to connect to the air supply structure 300.

[0095] In this embodiment, a first drag chain 240 and a second drag chain 250 are provided in the device body 200, and the air pipe 220 connecting the air supply structure 300 and the air inlet channel is passed through the first drag chain 240 and the second drag chain 250, thereby limiting and protecting the air pipe 220, preventing the air pipe 220 from being scattered and affecting the movement of the laser 100, and preventing the air pipe 220 from being damaged.

[0096] 4 , 6 and 7 , in one embodiment of the present application, the back panel 210 is provided with a first connecting portion 115 , and the outer shell 10 is provided with a connecting structure 16 . The first connecting portion 115 and the connecting structure 16 are engaged with each other through a card hole structure or plugged into each other through a slot structure.

[0097] It is understood that there are various ways to connect the first connection portion 115 and the connection structure 16, such as, but not limited to: when one of the first connection portion 115 and the connection structure 16 is a hook and the other is a hole, the hook and the hole are engaged with each other; when one of the first connection portion 115 and the connection structure 16 is a plug connector and the other is a slot 1151, the plug connector is engaged with the slot 1151. The first connection portion 115 and the connection structure 16 facilitate detachable connection between the laser 100 and the backplane 210.

[0098] 4 , 6 , and 7 , in one embodiment of the present application, the first connection portion 115 is configured as a slot 1151, and the connection structure 16 is configured as a plug connector, which plugs into and mates with the slot 1151. The plug connector and slot 1151 are plugged into and mate with each other, thereby facilitating assembly and disassembly of the laser 100 and improving the convenience of assembly and disassembly of the laser device 1.

[0099] Please refer to Figure 6. In one embodiment of the present application, the laser device 1 also includes a locking and releasing structure 16 movably provided on the back plate 210. The locking and releasing structure 16 has a locked state and an unlocked state. In the locked state, the locking and releasing structure 16 limits the plug connector to the slot 1151. In the unlocked state, the locking and releasing structure 16 is separated from the plug connector, and the plug connector can be removed from the slot 1151.

[0100] It can be understood that the lock-release structure 16 can be switched between the locked state and the unlocked state by rotation, or by movement, or by a combination of rotation and movement, and the specific details are not limited here.

[0101] When the plug connector is inserted into slot 1151, there is a gap between the plug connector and the slot wall of slot 1151, which affects the stability of the laser 100 installed on the back plate 210. To avoid this, in the locked state, the lock release structure 16 of this embodiment is inserted into slot 1151 and abuts against the plug connector. The abutment direction of the lock release structure 16 and the plug connector is arranged at an angle with the direction in which the plug connector is inserted into slot 1151, thereby restricting the plug connector within slot 1151. At this time, the plug connector cannot move within slot 1151, thereby ensuring that the plug connector is stably installed in slot 1151. In other words, the connecting structure 16 on the laser 100 can be stably installed on the first connecting portion 115. When the laser 100 needs to be removed from the back plate 210, the lock release structure 16 is separated from the connecting structure 16 in the unlocked state to release the restriction on the plug connector, allowing the plug connector to be removed from slot 1151, and the laser 100 can now be replaced.

[0102] Please refer to Figure 6. In one embodiment of the present application, the lock-release structure 16 includes a toggle member 161 and a locking accessory 162. The toggle member 161 is rotatably disposed on the back panel 210 and has a locking position and an unlocking position. The locking accessory 162 can enter and exit the slot 1151. During the process of rotating the toggle member 161 from the unlocking position to the locking position, the locking accessory 162 can be driven to enter the slot 1151 and abut against the plug connector, so that the plug connector is limited in the slot 1151.

[0103] It is understood that the back plate 210 is provided with a slot 1151, and the laser 100 is provided with a plug connector. By aligning the plug connector with the slot 1151 and inserting it, the laser 100 can be installed on the back plate 210. The lock release structure 16 includes a toggle member 161 and a locking attachment 162. The toggle member 161 is rotatably provided on the back plate 210, and the locking attachment 162 is movably provided on the back plate 210. The locking attachment 162 can be moved by driving the toggle member 161 to rotate. When the locking attachment 162 moves toward the side close to the plug connector, it can abut against the plug connector, and the locking attachment 162 can restrict the plug connector within the slot 1151. When the locking attachment 162 moves toward the side away from the plug connector, the locking attachment 162 separates from the plug connector, and the locking attachment 162 releases the restriction on the plug connector, allowing the plug connector to be removed from the slot 1151. The locking member 162 can be driven by the toggle member 161 to move away from the plug connector, or, as in the following embodiment, can be driven by the reset member 13 to move away from the plug connector. The toggle member 161 and locking member 162 of this embodiment simplify the method for locking and unlocking the plug connector, thereby simplifying the structure of the lock-release mechanism 16.

[0104] In one embodiment, the toggle member 161 includes a handle 1611 and a cam 1612 connected to each other. The hub surface of the cam 1612 abuts against the locking accessory 162. When the handle 161 is rotated, the cam 1612 is driven to rotate, so that the cam 1612 drives the locking accessory 162 to move.

[0105] Referring to FIG. 6 , in one embodiment of the present application, the lock-release structure 16 further includes a reset member 163 . The reset member 163 acts between the back plate 210 and the lock member 162 to drive the lock member 162 out of the slot 1151 .

[0106] In this embodiment, the toggle member 161 can drive the locking attachment 162 to move the locking attachment 162 toward the side of the plug connector. After the toggle member 161 is released, the locking attachment 16 can be moved away from the plug connector under the action of the reset member 163 to release the lock on the plug connector, so that the plug connector can enter and exit the slot 1151, thereby realizing the disassembly and assembly of the laser 100. The reset member 163 can be set as an elastic member such as a spring, or as a magnetic attraction structure or a magnetic repulsion structure. For example, the reset member 163 includes a first magnetic member and a second magnetic member that are relatively arranged. The first magnetic member is arranged on the locking attachment 162, and the second magnetic member is arranged on the back plate 210 and is located on the side of the locking attachment 163 away from the plug connector. The magnetic poles of the first magnetic member and the second magnetic member are opposite. When the toggle member 161 is released, the magnetic attraction between the first magnetic member and the second magnetic member drives the locking attachment 162 to move away from the plug connector to release the lock. In addition to locking the plug connector; or, the second magnetic member is provided on the back plate 210 and is located on the side of the lock accessory 163 facing the plug connector, and the first magnetic member and the second magnetic member have the same magnetic poles that are relatively arranged. When the toggle member 161 is released, the magnetic repulsion between the first magnetic member and the second magnetic member drives the lock accessory 162 to move away from the plug connector to release the lock on the plug connector; with this arrangement, the reset member 163 can provide a force for separating the limiting portion 3322 from the plug connector, so as to improve the smoothness of the separation of the lock accessory 162 from the plug connector.

[0107] In one embodiment, a plurality of restoring members 163 may be provided along the length direction of the locking member 162 , which is beneficial for improving the stability of the locking member 162 abutting against the restoring members 163 .

[0108] This application proposes a laser 100 .

[0109] 14 , 20 , and 21 , in one embodiment of the present application, the laser 100 includes a housing 10, a laser module 20, and a nozzle module 50. The housing 10 includes a housing 11 having an opening at the bottom thereof. At least a portion of the laser module 20 is movably disposed in the housing 11, with a light outlet 23 of the laser module 20 facing downward from the opening. The nozzle module 50 is disposed on the lower side of the laser module 20 and includes an air guide channel 513, a flow guide chamber 521, and an outlet 522. The flow guide chamber 521 is connected to the air guide channel 522. The air guide channel 513 can be connected to a gas source and guide the air flow to the flow guide chamber 521. The air flow is then blown out from the outlet 522 after passing through the flow guide chamber 521. The light outlet 23 of the laser module 20 is located in the flow guide chamber 521, and the outlet 522 coincides with the center line of the light outlet 23.

[0110] The laser 100 proposed in this application can be used in laser equipment 1 such as laser marking machines, laser engraving machines, laser cutting machines, and laser welding machines, and is used to emit laser light for processing operations such as laser marking, laser engraving, laser cutting, and laser welding. The laser 100 includes a housing 10 that serves as a support and mounting base. A housing 11 is formed within the housing 10, and an opening is provided at the bottom of the housing 10 to communicate with the housing 11. At least a portion of a laser module 20 is disposed within the housing 11, and the laser module 20 is capable of being raised and lowered. Alternatively, the laser module 20 may be positioned always within the housing 11 and only raised and lowered within the housing 11, with the light outlet 23 of the laser module 20 facing downwardly from the opening of the housing 11 to emit laser light outward. Alternatively, the laser module 20 may be capable of being raised and lowered and may enter and exit the housing 11 from the bottom opening of the housing 10. The height of the laser module 20 can be adjusted, thereby adjusting the height of the laser focus, so that the laser focus can be positioned at the processing position.

[0111] In addition, an air nozzle module 50 is provided in the laser 100. The air nozzle module 50 is provided on the lower side of the laser module 20. The air nozzle module 50 is formed with an air guide channel 513, a flow guide cavity 521 and an outlet 522 which are connected in sequence. The light outlet 23 is located in the flow guide cavity 521. 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 of the embodiment of the present application is used for processing, the nozzle module 50 can be connected to the air supply structure 300 as an air source. The air supply structure 300 supplies air to the nozzle module 50, and the air flow provided by the air supply structure 300 is blown outward through the air guide channel 513, the guide cavity 521, and the outlet 522 in sequence. This arrangement can blow away dust and smoke outside the outlet 522, and the continuous air flow can also prevent dust and other impurities from entering the guide cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to the window mirror or focusing lens, thereby avoiding affecting the laser emission. In addition, because the nozzle module 50 is fixed to the laser module 20, it can be raised and lowered with the laser module 20, so that the nozzle module 50 can always form an airflow at the front end of the nozzle 52 of the laser module 20. It can also blow the airflow toward the processing location, preventing the processing location from being contaminated by dust, playing a good dust-proof role, and ensuring the processing effect.

[0112] In this embodiment, an air guide channel 513 is provided in the air nozzle module 50, so there is no need to provide an air pipe extending to the light output position to communicate with the guide cavity 521, which can play the role of hiding the air path. There will be no air pipe under the laser module 20, thereby avoiding the problem of the air pipe easily interfering with other devices during laser processing, and making the appearance of the laser 100 neat and uniform.

[0113] It should be noted that in this embodiment, the air nozzle module 50 can be configured as a simple cover mounted on the light outlet 23 to form the air guide cavity 521, or it can be configured as a combined structure of the air guide member 51 and the air nozzle 52 as in the following embodiment. Furthermore, the air guide tube 220 can be directly extended from the external air source into the accommodating cavity 11 to connect to the air nozzle module 50. Alternatively, as in the following embodiment, a mounting port 13 can be provided on the housing 10 to connect to the external air source through the mounting port 13, and an air guide hose 55 can be provided in the accommodating cavity 11 to connect the mounting port 13 and the air nozzle module 50.

[0114] Optionally, the cross section of the guide cavity 512 may be configured to be tapered along the air outlet direction to converge the airflow so that the airflow is concentrated and blown out from the outlet 522 , thereby increasing the blowing force.

[0115] In addition, the laser 100 is also provided with a lifting module 30, which can be a screw transmission structure, a cylinder or liquid cylinder pushing structure, a linear motor structure, a turbine worm structure or a gear rack structure, so that the lifting module 30 is connected to the laser module 20 in a transmission manner, so that the laser module 20 and the air nozzle module 50 can be driven to rise and fall through the lifting module 30.

[0116] Therefore, it can be understood that in the technical solution of the present application, the laser module 20 in the laser 100 can be raised and lowered in the housing 10 by the lifting module 30 to adjust the height position of the laser focus; and, an air nozzle module 50 is provided to cover the light outlet 23, and the air nozzle module 50 is formed with a guide cavity 521, and is provided with an outlet 522 connected to the guide cavity 521, and the outlet 522 of the guide cavity 521 is arranged opposite to the light outlet 23 of the laser module 20, so that the laser can be emitted through the outlet 522. When the laser 100 of the present application is used for processing, the nozzle module 50 can be connected to the air supply structure 300. The air supply structure 300 supplies air to the nozzle module 50 and blows the air outward through the guide cavity 521 and the outlet 522, thereby blowing away dust and smoke outside the outlet 522. The continuous air flow can also prevent dust and other impurities from entering the guide cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting the laser emission. In addition, since the nozzle module 50 is fixed to the laser module 20, it can be raised and lowered together with the laser module 20, so that the nozzle module 50 can always form an airflow at the front end of the nozzle 52 of the laser module 20. The airflow can also be blown toward the position to be processed, preventing the position to be processed from being contaminated by dust, playing a good dust-proof role, and ensuring the processing effect.

[0117] By providing an air guide channel 513 in the air nozzle module 50, there is no need to provide an air pipe extending to the light output position to communicate with the guide cavity 521, which can play the role of hiding the air path. There will be no air pipe under the laser module 20, thereby avoiding the problem of the air pipe easily interfering with other devices during laser processing, and making the appearance of the laser 100 neat and uniform.

[0118] In addition, in the laser 100 of the present application, only partial structures such as the laser module 20 and the air nozzle module 50 are raised and lowered to adjust the height position of the laser focus and the blowing position. There is no need to raise and lower the laser 100 as a whole in the laser equipment 1, making the raising and lowering process of adjusting the height of the laser module 20 and the air nozzle module 50 easier.

[0119] Please refer to Figures 21 to 23. 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 below the laser module 20. An air guide channel 513 is provided in the air guide member 51. An end of the air guide channel 513 away from the light outlet 23 is provided with an access port for connecting to the air source. An end of the air guide member 51 close to the light outlet 23 is provided with a first chamber 514 that passes through both ends along the center line direction of the light outlet 23. The first chamber 514 is connected to the air guide channel 513; the air nozzle 52 cover is arranged on 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 is connected to the first chamber 514 to form a guide chamber 521 in combination.

[0120] In this embodiment, the air nozzle module 50 includes an air guide member 51, an air nozzle 52 and an air pipe joint 56, and the air nozzle 52 and the air guide member 51 are both covered below the laser module 20, wherein the air guide member 51 includes an air guide portion 511 and a connecting portion 512 connected to each other, and an air guide channel 513 is formed in the air guide portion 511, and the connecting portion 512 is covered at the position of the light outlet 23, and a first chamber 514 is opened, and the air guide channel 513 and the first chamber 514 are interconnected through the air guide port; the air nozzle 52 is covered on the side of the air guide member 51 facing away from the laser module 20, and is interconnected with the connecting portion 512 of the air guide member 51, so that the air nozzle 52 and the air guide member 51 are integrated, thereby improving the overall structural stability of the air nozzle module 50; of course, the air nozzle 52 and the air guide member 51 can also be detachably connected. The air nozzle 52 is provided with a second chamber 523, which communicates with the first chamber 514 to form a guide chamber 521. The air guide 51 is provided with an access port at a position away from the guide chamber 521. The access port is connected to an air pipe connector to facilitate connection of the air pipe. This eliminates the need to extend the air pipe 220 connected to the air source directly to a position adjacent to the light outlet 23 of the laser module 20, thereby preventing the air pipe 220 from blocking the light or otherwise affecting the laser processing process.

[0121] Referring to Figure 24 , in some embodiments of the present application, the air nozzle 52 is detachably connected to the air guide 51. The detachable connection between the air nozzle 52 and the air guide 51 can be achieved by at least one of threaded, bolted, magnetic, and snap-fit ​​connections.

[0124] Please refer to Figure 24. In some embodiments of the present application, one of the air guide part 51 and the air nozzle 52 is provided with a magnet 53, and the other of the air guide part 51 and the air nozzle 52 is provided with a magnetic conductive part 54. The magnetic conductive part 54 is arranged around the circumference of the guide cavity 521 and is magnetically attracted to the magnet 53.

In addition, the magnetic conductive member 54 is arranged around the circumference of the guide cavity 521, and the magnet 53 can also be arranged around the circumference of the guide cavity 521, or at least two magnets 53 are arranged at intervals along the circumference of the guide cavity 521, so that the air nozzle 52 can be detachably connected to the air guide member 51 through the magnetic attraction between the magnet 53 and the magnetic conductive member 54, and the air nozzle 52 is evenly stressed along the circumference of the guide cavity 521, thereby improving the installation stability.

[0126] Please refer to Figures 23 and 24. In some embodiments of the present application, a limiting step 515 is provided on the side of the air guide 51 facing away from the laser module 20. The first chamber 514 is provided on the limiting step 515, and part of the air nozzle 52 is embedded in the limiting step 515.

[0127] In this embodiment, a limiting step 515 is formed on the surface of the air guide 51 facing the air nozzle 52, and at least a portion of the air nozzle 52 is embedded in the limiting step 515, which can not only play a positioning role when installing the air nozzle 52 and improve the convenience of installation; but also prevent the air nozzle 52 from shifting on the surface of the air guide 51, ensuring that the light outlet 23 of the laser module 20 is arranged relative to the outlet 522 of the air nozzle 52, thereby ensuring that the laser can be emitted from the outlet 522 of the air nozzle 52.

[0128] Referring to FIG. 24 , in some embodiments of the present application, the air nozzle module 50 further includes a sealing gasket 57 . The sealing gasket 57 is sandwiched between the air nozzle 52 and the air guide member 51 and is disposed around the guide cavity 521 .

[0129] In this embodiment, a sealing gasket 57 is arranged between the air guide member 51 and the air nozzle 52, and the sealing gasket 57 is arranged around the guide cavity 521; and the sealing gasket 57 is usually elastic and can be elastically deformed by the squeezing of the air guide member 51 and the air nozzle 52 to fit tightly against the air guide member 51 and the air nozzle 52, thereby improving air tightness and preventing gas from leaking from between the air nozzle 52 and the air guide member 51.

[0130] In one embodiment of the present application, a groove 516 is formed on the surface of the air guide 51 facing the laser module 20. This configuration can reduce the weight of the air guide 51, making the laser module 20 easier to lift.

[0131] Please refer to Figures 21 and 22. In some embodiments of the present application, the housing 10 is provided with a mounting port 13, and the laser 100 further includes an air inlet connector 90 and an air hose 55. The air inlet connector 90 is provided in the accommodating cavity 11 and is provided at the mounting port 13; the air hose 55 is bent and extended in the accommodating cavity 11, one end of the air hose 55 is connected to the air inlet connector 90, and the other end of the air hose 55 is connected to the air pipe connector 56; wherein, the air hose 55 adaptively deforms as the laser module 20 rises and falls.

[0132] In the embodiment of the present application, the laser module 20 and other components of the laser 100 are movable while the housing 10 and some structures are kept fixed, thereby making it easier to adjust the laser focus height. In this embodiment, a mounting port 13 is provided on the housing 10, an air inlet connector 90 is mounted at the mounting port 13, and an air hose 55 is disposed in the accommodating chamber 11. The air hose 55 can be bent and deformed as needed. The air hose 55 can be made of plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), or other materials. One end of the air guide hose 55 is connected to the air inlet connector 90, and the other end of the air guide hose 55 is connected to the air pipe connector 56, 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 connector 90, and the air guide hose 55 is partially bent; with this arrangement, when the air nozzle module 50 rises and falls with the laser module 20, the air guide hose 55 can produce adaptive deformation to move with the air nozzle module 50, maintain connection with the air nozzle module 50, make the air flow more stable, and ensure the air blowing and dust removal effect.

[0133] In this embodiment, the external gas source is connected to the air inlet connector 90 fixed to the outer shell 10, and the outer shell 10 does not move up and down in the laser device 1, thereby avoiding that the connecting structure between the external gas source and the laser 100 is pulled as the laser module 20 and the air nozzle module 50 are raised and lowered when the height of the laser module 20 and the air nozzle module 50 are adjusted, and there is no need to reserve a longer connecting structure to adapt to the raising and lowering of the laser module 20, thereby avoiding interference and improving the stability and safety of the raising and lowering process of the laser module 20.

[0135] In this embodiment, the air pipe connector 56 includes a first connector 561 inserted into the access port of the air guide member 51, and a second connector 562 connected to the first connector 561. The second connector 562 extends upward along the lifting direction of the laser module 20, so that when the air guide hose 55 is connected to the air pipe connector 56, the air guide hose 55 extends along the height direction, so that the bending 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, thereby reducing the interference of the air guide hose 55 on the lifting and lowering of the laser module 20, making the airflow more stable.

[0136] Referring to FIG. 14 to FIG. 19 , in some embodiments of the present application, the laser 100 further includes a heat dissipation module 40 , which is disposed in the accommodating cavity 11 .

In addition, the heat dissipation module 40 can be raised and lowered along with the laser module 20, or the heat dissipation module 40 can be fixed to the housing 10. Alternatively, in the following embodiment, the heat dissipation fan 41 can be fixed to the housing 10, and the heat dissipation fins and the like can be fixed to the laser module 20 to improve the heat dissipation efficiency of the laser module 20.

[0138] Referring to Figure 21 , in some embodiments of the present application, the laser module 20 is provided with a lens barrel 22 inserted into a flow guiding cavity 521. A light outlet 23 is formed at one end of the lens barrel 22 facing the outlet 522, so that the air inlet of the flow guiding cavity 521 is disposed opposite the sidewall of the lens barrel 22. With this arrangement, the outer wall of the lens barrel 22 can be utilized to guide the airflow, causing the airflow to flow along the sidewall of the lens barrel 22 toward the side of the lens barrel 22 facing away from the heat dissipation outlet 12, and then to flow downward and be blown out from the outlet 522.

[0139] In one embodiment of the present application, a window mirror is provided at the light outlet 23 , so as to prevent dust, smoke, and airflow from the nozzle module 50 from entering the laser module 20 through the light outlet 23 .

[0140] In some embodiments, the laser module 20 can include a laser generator 21 and a lens barrel 22, the laser generator 21 is used to generate laser, and the lens barrel 22 is set at the light output position of the laser generator 21. Only a window mirror can be set in the lens barrel 22, and the focusing mirror is set in the laser generator 21; the lens barrel 22 can also include a connected focusing lens group 222 and a window lens group 221, that is, the focusing mirror and the window lens are both set 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 the focusing lens group 222 and the 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 and the focusing lens group 222 are socketed or threaded.

[0141] Please refer to Figures 15 to 19. In some embodiments of the present application, a heat dissipation port 12 communicating with the accommodating cavity 11 is provided at 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 provided in the accommodating cavity 11 and is located above the laser module 20. The air outlet of the heat dissipation fan 41 is set toward the laser module 20.

[0142] In this embodiment, the heat dissipation module 40 includes a cooling fan 41, which is mounted on top of the laser module 20 and has a heat dissipation port 12 formed on the bottom wall of the accommodating chamber 11. This arrangement allows the cooling fan 41 to direct external airflow into the accommodating chamber 11 and downward, dissipating heat from the structures within the accommodating chamber 11. Furthermore, since the cooling fan 41 is fixedly connected to the housing 10, there is no need to raise or lower the cooling fan 41 with the laser module 20, making the process of controlling the raising and lowering of the laser module 20 much simpler.

[0143] 18 and 22 , 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.

[0144] In this embodiment, a mounting plate 14 is provided in the accommodating cavity 11, the mounting plate 14 is fixedly connected to the outer shell 10, and a vent 141 is provided 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 arrangement 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.

[0145] Please refer to Figures 17 to 19. In some embodiments of the present application, the heat dissipation module 40 includes a heat sink provided on at least one side surface of the laser module 20. The heat sink is connected to the laser module 20. The surface of the heat sink facing away from the laser module 20 has a plurality of heat dissipation fins, and the plurality of heat dissipation fins are arranged side by side.

[0146] In this embodiment, a heat sink can be set only on one side surface of the laser module 20, or a heat sink can be set on both sides of the laser module 20 facing away from each other. The heat sink is provided with a plurality of heat dissipation fins arranged side by side. The heat sink can be made of a material with good thermal conductivity and heat dissipation performance, such as aluminum, aluminum alloy, copper or copper alloy, so that the heat on the laser module 20 can be quickly transferred to the heat sink, and the plurality of heat dissipation fins on the heat sink form a larger heat dissipation area 421, so that the heat transferred to the heat sink can be quickly dissipated.

[0147] Referring to Figures 17 to 19 , in some embodiments of the present application, the heat dissipation module 40 includes a heat dissipation fan 41 disposed above the laser module 20, with a plurality of heat dissipation fins arranged horizontally. This arrangement allows the heat dissipation fins to extend generally along the direction of the airflow driven by the heat dissipation fan 41, forming airflow paths between adjacent heat dissipation fins. This allows airflow through the radiator to pass through each airflow path, fully contacting each heat dissipation fin and removing heat from each heat dissipation fin, thereby improving the heat dissipation efficiency of the radiator. Furthermore, arranging the heat dissipation fins horizontally prevents airflow from directly impacting the surface of the heat dissipation fins and being obstructed, thereby affecting the normal flow of airflow.

[0148] In some embodiments, the lifting module 30 in the laser 100 can be connected to a heat sink, and the laser module 20 can be lifted and lowered by driving the heat sink up and down. For ease of explanation, in the following embodiments, the heat sink connected to the lifting module 30 is defined as the first heat sink 42, and the heat dissipation fins on the first heat sink 42 are first heat dissipation fins 423. When the heat dissipation module 40 includes two heat sinks disposed on opposite sides of the laser module 20, the other heat sink not connected to the lifting module 30 is defined as the second heat sink 43, and the heat dissipation fins on the second heat sink 43 are second heat dissipation fins 431.

[0149] Referring to FIG. 19 , in some embodiments of the present application, the lifting module 30 is connected to the first heat sink 42 to drive the first heat sink 42 to move the laser module 20 up and down.

[0150] In this embodiment of the present application, a first heat sink 42 is fixed to a side surface of the laser module 20, and the lifting module 30 is connected to the first heat sink 42. By driving the first heat sink 42 up and down, the laser module 20 is also lifted up and down. This arrangement prevents the lifting module 30 and the laser module 20 from being blocked by the first heat sink 42 during assembly and disassembly, thereby improving assembly and disassembly convenience.

[0151] Please refer to Figure 19. In some embodiments of the present application, the side of the first heat sink 42 facing away from the laser module 20 includes a heat dissipation area 421 and an avoidance area 422 arranged side by side in a horizontal direction. The heat dissipation area 421 is provided with a plurality of first heat dissipation fins 423. The lifting module 30 is opposite to the avoidance area 422 and is connected to the avoidance area 422.

[0152] In this embodiment, a heat dissipation zone 421 and an avoidance zone 422 are provided on the surface of the first heat dissipation zone 421 facing away from the laser module 20. The lifting module 30 is provided in the area where the avoidance zone 422 is located, so as to be opposite to and connected to the avoidance zone 422. A plurality of first heat dissipation fins 423 are provided in parallel in the heat dissipation zone 421. This arrangement can reduce the overall thickness of the lifting module 30 and the first heat sink 42 when they cooperate with each other, thereby reducing the volume of the laser 100. It should be noted that the avoidance zone 422 may not have any first heat dissipation fins 423, or may have first heat dissipation fins 423 partially conforming to the outer surface of the lifting module 30, thereby improving space utilization and the heat dissipation efficiency of the first heat sink 42.

[0153] 18 and 22 , in some embodiments of the present application, the laser 100 further includes an optical axis 15 , which is disposed in the accommodating cavity 11 and extends along the lifting direction of the laser module 20 , and the first heat sink 42 is liftably mounted on the optical axis 15 .

[0154] In this embodiment, an optical axis 15 extending along the height of the laser 100 is provided in the accommodating cavity 11, and the first heat sink 42 is sleeved on the optical axis 15. Thus, the optical axis 15 guides and limits the lifting and lowering of the first heat sink 42 and the laser module 20, thereby improving the stability of the first heat sink 42 and the laser module 20 during the lifting and lowering process. A single optical axis 15 can be provided, or at least two optical axes 15 can be provided side by side, thereby balancing the forces and forming multiple limits, further improving the stability of the first heat sink 42 and the laser module 20 during the lifting and lowering process.

[0155] 18 and 22 , in some embodiments of the present application, a sliding hole 424 extending along the lifting direction is opened on 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 .

[0156] In this embodiment, a sliding hole 424 extending along the height direction of the laser 100 is opened on the first heat sink 42, and a linear bearing 425 is installed in the sliding hole 424, so that the linear bearing 425 cooperates with the optical axis 15, thereby reducing the sliding friction between the first heat sink 42 and the optical axis 15, and improving the smoothness and stability of the lifting process of the first heat sink 42 and the laser module 20.

[0157] Please refer to Figures 19, 25 and 26. In some embodiments of the present application, the lifting module 30 of the laser 100 is arranged in the accommodating cavity 11. The lifting module 30 includes a driving member 31 connected to the outer shell 10 and a lifting rod 32 connected to the laser module 20. The lifting rod 32 extends along the lifting direction of the laser module 20, and the driving member 31 is used to drive the lifting rod 32 to rise and fall.

[0158] In this embodiment, the lifting module 30 includes a driving member 31 and a lifting rod 32; wherein the driving member 31 is in transmission connection with the lifting rod 32, and the driving member 31 and the lifting rod 32 can be the pump body and piston rod of an air cylinder or a liquid cylinder, respectively; the driving member 31 and the lifting rod 32 can also form a motor screw assembly; or a motor and a rack or worm, connected by a gear or turbine transmission; all of which can form a drive structure in which the driving member 31 drives the lifting rod 32 to rise and fall. 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 move the laser module 20 up and down.

[0159] Please refer to Figures 25 and 26. In some embodiments of the present application, the lifting module 30 also includes a lower dust cover 33, which is mounted 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 be extended and retracted as the lifting rod 32 is raised and lowered.

[0160] In this embodiment, a lower dust cover 33 is sleeved on the outer side of the lifting rod 32 of the extended driving member 31. The lower dust cover 33 can be retracted and made of elastic material, or the lower dust cover 33 can be set as a corrugated cover in the following embodiment, so that the lower dust cover 33 can shrink and stretch as the lifting rod 32 rises and falls. The lower end of the 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 closed dustproof space is formed in the lower dust cover 33, and the opening at the lower end of the driving member 31 for passing the lifting rod 32 is covered. It can prevent dust, oil and other impurities from being contaminated on the lifting rod 32, and can also prevent dust, oil and other impurities from entering the driving member 31 from the opening at the lower end of the driving member 31 for passing the lifting rod 32. In this way, dust, oil and other impurities can be prevented from being blocked between the driving member 31 and the lifting rod 32, ensuring that the driving member 31 will not be blocked by impurities when driving the lifting rod 32 to move, thereby ensuring that the operation process of the lifting module 30 is smooth and stable.

[0161] Referring to FIG. 25 , in some embodiments of the present application, at least a portion of the lower dust cover 33 is corrugated.

[0162] In this embodiment, at least a portion of the lower dust cover 33 is configured as a corrugated structure composed of a plurality of sequentially connected corrugated segments. The corrugated segments can be folded relative to each other to shorten the length of the lower dust cover 33, or can be stretched relative to each other to lengthen the lower dust cover 33. Alternatively, the entire lower dust cover 33 can be configured as a retractable corrugated structure, which maximizes the range of length extension and contraction of the lower dust cover 33 and provides a wide range of applications. Alternatively, a portion of the lower dust cover 33 can be configured as a retractable corrugated structure, which allows the minimum retracted length of the lower dust cover 33 to be set by adjusting the length of the non-corrugated segments, thereby preventing the lower dust cover 33 from being punctured by the lifting rod 32 due to excessive contraction and thus affecting the dustproof effect.

[0163] Please refer to Figures 25 and 26. In some embodiments of the present application, the lifting module 30 also includes a fixed base 34, the fixed base 34 is provided with a through hole 341, the fixed base 34 is connected to the shell 10, the driving member 31 is provided on the fixed base 34, and the lifting rod 32 is provided through the through hole 341 and extends downward, and can move up and down relative to the through hole 341.

[0164] In this embodiment, the lifting module 30 further includes a fixing base 34, which is used to secure the lifting module 30 to the device at the location to be installed. For example, when the lifting module 30 is used in the laser 100, the fixing base 34 can be fixedly connected to the housing 10 of the laser 100. In the lifting module 30, the driving member 31 is fixed to the fixing base 34, and the lifting rod 32 is inserted through a through hole 341 provided in the fixing base 34. The lower dust cover 33 can be extended and retracted between the fixing base 34 and the bottom end of the lifting rod 32. The lower dust cover 33 can be connected to the fixing base 34, or one end of the lower dust cover 33 can be inserted through the through hole 341 and connected to the driving member 31. The provision of the fixing base 34 can improve the installation stability of the lifting module 30 and facilitate the fixing of the lifting module 30 at the location to be installed, without requiring a dedicated support structure in the device to secure the lifting module 30.

[0165] 25 and 26 , in some embodiments of the present application, a clamping portion 331 is provided at the first end of the lower dust cover 33 , the lower dust cover 33 is passed through the through hole 341 , and the clamping portion 331 is clamped between the fixing seat 34 and the driving member 31 .

[0166] In this embodiment, a clamping portion 331 is provided at the first end of the lower dust cover 33 near the driver 31, and the lower dust cover 33 is inserted into the through hole 341 of the fixing seat 34, so that the clamping portion 331 is located between the fixing seat 34 and the driver 31 and is clamped and fixed by the fixing seat 34 and the driver 31, thereby improving the connection strength and position stability of the end of the lower dust cover 33 near the driver 31 and preventing the end of the lower dust cover 33 near the driver 31 from loosening and falling. The clamping portion 331 can be provided at only one position along the circumference of the lower dust cover 33. In some embodiments, the clamping portion 331 can be a sheet-like structure arranged along the circumference, or can be two or more connecting ears distributed along the circumference.

[0167] Please refer to Figure 19. In some embodiments of the present application, the lifting module 30 also includes a protective pad 35, which 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 size of the protective pad 35 is not smaller than the cross-sectional size of the lower dust cover 33.

[0168] In this embodiment, the lifting module 30 is also equipped with a protective pad 35. The protective pad 35 can be made of, but is not limited to, vacuum panels, glass wool, expanded perlite, glass fiber mats, or materials such as polystyrene foam. The pad 35 provides at least one of fireproofing and heat insulation. The pad 35 is mounted on the bottom end of the lifting rod 32, with the lower dust cover 33 positioned above the pad 35, between the second end of the lower dust cover 33 and the bottom end of the lifting rod 32. Furthermore, the cross-sectional dimensions of the pad 35 are not smaller than those of the lower dust cover 33. This arrangement allows the lifting module 30 to be used in laser equipment, isolating the lower dust cover 33 from the processing position and the laser beam. This prevents heat generated by the laser beam or during processing from being transferred to the lower dust cover 33, thereby preventing the lower dust cover 33 from catching fire or otherwise damaging it, and improving operational safety. Furthermore, the pad 35 also provides a certain degree of dustproofing, blocking dust and oil stains, thereby enhancing the dustproof performance of the lifting module 30.

[0169] In some embodiments, the cross-sectional profile of the position on the lifting rod 32 for mounting the protective pad 35 can be made non-circular, and the shape of the sleeve hole on the protective pad 35 can be adapted to the cross-sectional shape of the lifting rod 32, thereby preventing the protective pad 35 from rotating on the lifting rod 32.

[0170] Please refer to Figures 25 and 26. In some embodiments of the present application, the driving member 31 is a motor, the lifting rod 32 is a screw rod, the motor has a mounting hole 311 that passes through along the length direction of the screw rod, and the screw rod is inserted into the mounting hole 311 and can extend outward along the openings at both ends of the mounting hole 311.

[0171] In this embodiment, the lifting module 30 is a through-type screw motor module, wherein the lifting rod 32 is a screw, the driving member 31 is a motor, and the motor is provided with a mounting hole 311 extending along the length of the screw. The screw is inserted into the mounting hole 311 and can extend from the openings at both ends of the mounting hole 311 to the top and bottom of the driving member 31. The rotor in the motor is threadedly connected to the screw, so that when the rotor rotates, the screw can be driven to move along the length of the screw. By using a through-type screw motor module as the lifting module 30, the lifting module 30 occupies a smaller space, and the space at the upper and lower ends of the motor can be fully utilized for the screw movement, thereby reducing the size of the devices and equipment using the lifting module 30.

[0172] Please refer to Figure 19. In some embodiments of the present application, the lifting module 30 also includes an upper dust cover 36. The upper dust cover 36 covers the opening at one end of the mounting hole 311 away from the lower dust cover 33. A movable space with a lower opening is provided in the upper dust cover 36. The part of the screw rod extending above the motor is accommodated in the movable space and can move relative to the movable space.

[0173] In the aforementioned embodiment, a through-type screw motor module is used as the lifting module 30. In this case, the screw can protrude from the upper end of the motor. In this embodiment, an upper dust cover 36 is provided at the end of the motor that is away from the lower dust cover 33. The upper dust cover 36 covers the upper opening of the mounting hole 311. A movable space connected to the mounting hole 311 is formed in the upper dust cover 36. At this time, the upper dust cover 36 can shield the screw and the mounting hole 311, preventing impurities such as dust and oil from adhering to the part of the screw protruding from the top of the motor, and preventing impurities such as dust and oil from entering the motor through the upper opening of the mounting hole 311. This can prevent impurities such as dust and oil from being blocked between the driving member 31 and the lifting rod 32, ensuring that the driving member 31 will not be blocked by impurities when driving the lifting rod 32 to move, thereby ensuring smooth and stable operation of the lifting module 30.

[0174] Please refer to Figures 25 and 26. In some embodiments of the present application, the upper dustproof cover 36 includes a dustproof portion 361 and a support portion 362. The support portion 362 is covered on the motor. The dustproof portion 361 is connected to an end of the support portion 362 away from the motor and extends along the axial direction of the lifting rod 32. The radial dimension of the support portion 362 is larger than the radial dimension of the dustproof portion 361, and a movable space is provided in the dustproof portion 361.

[0175] In this embodiment, the upper dustproof sleeve 36 includes a dustproof portion 361 and a support portion 362. The support portion 362 abuts against the motor. The dustproof portion 361 is connected to the end of the support portion 362 away from the motor, and has a roughly cylindrical structure, forming an activity space with an opening on the lower side. The radial dimension of the support portion 362 is larger than the radial dimension of the dustproof portion 361. With this arrangement, the support portion 362 is used to increase the contact area with the motor, thereby improving the connection strength between the upper dustproof sleeve 36 and the motor.

[0176] Referring to FIG. 18 , in some embodiments of the present application, the laser 100 further includes a position detection module 60 . The position detection module 60 is disposed in the accommodating cavity 11 and is used to detect the position of the laser module 20 .

[0177] In the embodiment of the present application, the laser module 20 can be raised and lowered relative to the housing 10, so that the height of the light outlet 23 of the laser module 20 can be adjusted according to the height of different processing positions to improve the processing accuracy and processing effect. In addition, before each laser processing, the laser module 20 needs to be raised and reset to a preset origin position, so as to facilitate the control of the lifting module 30 to operate and lower the laser module 20 to the desired position. In this embodiment, a position detection module 60 is set in the laser 100 to detect the position of the laser module 20, wherein the position detection module 60 can detect the height of the laser module 20, and can also be used to detect whether the laser module 20 is raised and reset to a preset origin position, thereby improving the accuracy of height adjustment of the laser module 20. The position detection module 60 can be at least one of a proximity switch, a photoelectric detection switch, a grating scale detection module, a Hall sensor, etc., which is not limited here.

[0178] With reference to Figures 18, 27, and 28, in some embodiments of the present application, the position detection module 60 is used to detect whether the laser module 20 has returned to a preset origin position. The position detection module 60 includes a mounting shell 61, a sensing module 63, and a first resetting 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 sensing module 63 includes a movable member 631, a first trigger member 633, and a first sensing member 635. The movable member 631 can be movably inserted into the first through hole 614 and has The first position and the second position; the first trigger member 633 and the first sensing member 635 are both located in the mounting cavity 613, one of the first trigger member 633 and the first sensing member 635 is provided 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 provided in the mounting cavity 613, and acts between the mounting shell 61 and the movable member 631, so that the movable member 631 has a tendency to remain in the second position.

[0179] Specifically, the mounting housing 61 serves as the mounting base for the position detection module 60 and defines a mounting cavity 613 therein. The outer contour of the mounting housing 61 can be a rectangular parallelepiped, cube, cylinder, prism, or other regular or irregular structures. The mounting cavity 613 therein can conform to the outer contour or be configured in other shapes. The mounting housing 61 can include an upper housing 611 and a lower housing 612 that cover each other, or it can be configured with a side-opening door to allow access to the mounting cavity 613 for assembly and disassembly of the internal components. The movable part 631 of the sensing module 63 is passed through the first through hole 614 opened on the mounting shell 61 and extends out of the mounting cavity 613. The movable part 631 can slide relative to the mounting shell 61 along the direction of the central axis of the first through hole 614 and has a first position and a second position; in addition, a first reset member 65 is provided between the movable part 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 provided on the side of the top wall opposite to the first through hole 614, and apply an elastic thrust toward the side of the first through hole 614 to the movable part 631, so that the movable part 631 has a tendency to move from the first position to the second position and maintain the second position; the elastic member can also be provided on the cavity wall with the first through hole 614, and connected to the movable part 631 to apply an elastic pulling force to the movable part 631, which can also make the movable part 631 have a tendency to move from the first position to the second position and maintain the second position. The first reset member 65 may also be a magnetic structure, which may include a first magnetic member and a second magnetic member respectively provided on the movable member 631 and the mounting shell 61. A magnetic attraction may exist between the first magnetic member and the second magnetic member, and the magnetic attraction force causes the movable member 631 to have a tendency to move from the first position to the second position and remain in the second position. A magnetic repulsion force may also exist between the first magnetic member and the second magnetic member, and the magnetic repulsion force may 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 moved into the mounting cavity 613 by an external force, it will overcome the force applied by the first reset member 65. When the external force applied to the movable member 631 is removed, the force applied to the movable member 631 by the first reset member 65 will cause the movable member 631 to move to the second position.

[0180] The sensing module 63 also includes a first triggering member 633 and a first sensing member 635 disposed in the mounting cavity 613. The first sensing member 635 can be connected to the mounting housing 61, and the first triggering member 633 can be disposed on the movable member 631 so that the first triggering member 633 moves with the movable member 631 relative to the first sensing member 635. When the movable member 631 moves from the second position to the first position, the first triggering member 633 triggers the first sensing member 635, causing the first sensing member 635 to emit a sensing signal. In this embodiment of the present application, the first triggering member 633 can also be connected to the mounting housing 61, and the first sensing member 635 can be disposed on the movable member 631 so that it moves with the movable member 631 relative to the first triggering member 633. When the movable member 631 moves from the second position to the first position, the first triggering member 633 can also trigger the first sensing member 635, causing the first sensing member 635 to emit a sensing signal.

[0181] The first sensing element 635 can be configured as a Hall effect sensor, a photoelectric switch, a proximity switch, a grating readout head, or the like. For example, if the first sensing element 635 is a Hall effect sensor and the first triggering element 633 is configured as a magnet 53, when the first triggering element 633 moves with the movable element 631 between the first and second positions, the magnetic field strength surrounding the Hall effect sensor changes, for example, from weak to strong or from strong to weak. Using the magnetic field strength detected by the Hall effect sensor when the first triggering element 633 is in the first position as a trigger condition, the Hall effect sensor can emit a sensing signal when the first triggering element 633 reaches the first position. If a proximity switch is used as the first sensing element 635, the first triggering element 633 can contact the sensing surface of the proximity switch when the movable element 631 is in the first position, thereby causing the proximity switch to emit a sensing signal. If a grating reading head is used as the first sensing element 635, and the first triggering element 633 is a scale grating extending along the movable direction of the movable element 631, when the movable element 631 moves from the second position to the first position, the scale grating and the grating reading head move relative to each other. The grating reading head can read the displacement relative to the scale grating and convert the displacement into an electrical signal. The signal processing circuit processes the displacement data, thereby generating a sensing signal when the first triggering element 633 moves a corresponding distance from the second position to the first position. The use of other structures as the sensing module 63 is not detailed here.

[0182] In this embodiment, the movable member 631 is positioned relative to at least a portion of the laser module 20 in the height direction. When the laser module 20 rises relative to the mounting housing 61 to reset to the origin, the laser module 20 pushes the first trigger member 633 upward. When the laser module 20 reaches the preset origin, the movable member 631 moves to the first position, causing the first trigger member 633 to trigger the first sensing member 635 to emit a sensing signal indicating that the laser module 20 has reset. This sensing signal is then fed back to the controller to control the laser module 20 to stop moving. This arrangement allows for relatively precise control of the laser module 20's reset to the origin. Because both the first sensing member 635 and the first trigger member 633 of the position sensing module 63 are located within the mounting housing 61, external dust and oil contamination are not present, ensuring the stable performance of the position detection module 60. This ensures that the position detection module 60 can accurately detect and provide feedback on the status of the laser module 20 when it reaches the reset position.

[0183] The first trigger member 633 and the first sensing member 635 are both arranged in the installation cavity 613, and will not be contaminated or interfered by external dust, oil and other debris, thereby reducing the risk of problems such as poor detection or false triggering, and ensuring the performance stability and detection accuracy of the position detection module 60.

[0184] 27 and 28 , in some embodiments of the present application, the first restoring member 65 is an elastic member, which is disposed between the movable member 631 and the cavity wall of the installation cavity 613 along the movable direction of the first trigger member 633 .

[0185] In this embodiment, the first reset member 65 can be an elastic member such as a spring, a gas spring, or an elastic airbag. The elastic member can be arranged on the side of the top wall opposite to the first through hole 614, and located between the top wall and the movable member 631 to apply an elastic thrust toward the side of 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.

[0186] The elastic member can also be arranged on the cavity wall with the first through hole 614 and connected to the movable member 631 to apply 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 maintain the second position.

[0187] Specifically, when the movable part 631 is not affected by external force, the movable part 631 is in the second position due to the elastic force of the elastic part; in the process of the movable part 631 being moved into the installation cavity 613 by the external force to move to the first position, the elastic part is elastically deformed by the force and generates an elastic force in the opposite direction of the external force. When the external force acting on the movable part 631 is cancelled, the elastic part will restore its shape and move the movable part 631 to the second position.

[0188] Please refer to Figures 28 and 29. In some embodiments of the present application, the installation cavity 613 has a top wall arranged opposite to the first through hole 614, and a limiting column 6315 is provided at one end of the movable part 631 facing the top wall, and the elastic part is sleeved on the limiting column 6315.

[0189] In this embodiment, the mounting cavity 613 has a top wall arranged opposite to the first through hole 614, and the elastic member is arranged between the top wall of the mounting 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.

[0190] At the same time, a stop post 6315 is protruded from one end of the movable member 631 that faces the top wall. The stop post 6315 can be integrally formed with the movable member 631, or can be detachably or non-detachably connected to the movable member 631. Furthermore, the elastic member is sleeved onto the stop post 6315, for example, by having a spring sleeved onto the stop post 6315, or by having the elastic airbag be configured as an annular inflatable ring sleeved onto the stop post 6315; or by having the piston rod of the gas spring be configured as a hollow rod sleeved onto the stop post 6315. This configuration improves the positional stability of the elastic member, prevents displacement of the elastic member, ensures that the elastic member can stably act on the movable member 631, and guarantees overall structural stability and performance stability.

[0191] 28 and 29 , in some embodiments of the present application, a limiting hole 6317 is provided at one end of the movable part 631 facing the top wall, and part of the limiting column 6315 is inserted into the limiting hole 6317 ; or, the limiting column 6315 and the movable part 631 are integrally formed.

[0192] In this embodiment, the limiting post 6315 can be integrally formed with the movable member 631. With this arrangement, the limiting post 6315 and the movable member 631 have a high connection strength, and the relative position between the limiting post 6315 and the movable member 631 is relatively stable, thereby improving the stability of the overall structure. In some embodiments, the limiting post 6315 can also be detachably connected to the movable member 631. When the limiting post 6315 and the movable member 631 are detachably connected, a limiting hole 6317 can be provided at the end of the movable member 631 away from the first through hole 614, and a portion 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 detach from the movable member 631, thereby ensuring that the elastic member stably acts on the movable member 631, thereby improving the stability of the overall structure. In addition, one end of the elastic member facing the movable member 631 can also be inserted into the limiting hole 6317 to further limit the elastic member. Of course, a countersunk hole 6319 can be opened on the end face of the movable member 631, and a limiting hole 6317 can be opened on the bottom wall of the countersunk hole 6319, so that one end of the elastic member is inserted into the countersunk hole 6319 and abuts against the bottom wall of the countersunk hole 6319, and one end of the limiting column 6315 is passed through the countersunk hole 6319 and inserted into the limiting hole 6317.

[0193] In addition, in some embodiments, the limiting column 6315 can be passed through the cavity wall of the installation cavity 613 and arranged opposite to the first through hole 614, so as to provide auxiliary positioning and limiting functions for the movable part 631 and prevent the movable part 631 from deflecting; at this time, the connection strength between the limiting column 6315 and the movable part 631 is improved and the relative position between the limiting column 6315 and the movable part 631 is ensured to be stable, so as to avoid the problem that the limiting column 6315 interferes with the movement of the movable part 631 due to the deviation of the limiting column 6315.

[0194] 28 , in some embodiments of the present application, the mounting shell 61 defines a second through hole 615 opposite to the first through hole 614 , and one end of the movable member 631 located in the mounting cavity 613 is inserted into the second through hole 615 .

[0195] In this embodiment, a second through hole 615 can be provided in the mounting housing 61, opposite to the first through hole 614. For example, the second through hole 615 can be provided on a top wall opposite to the first through hole 614, or a limiting plate can be provided in the mounting cavity 613, with the second through hole 615 provided in the limiting plate. Simultaneously, one end of the movable member 631 located in the mounting cavity 613 is inserted into the second through hole 615. This arrangement provides positioning and limiting functions for the movable member 631 at different positions along its length, preventing the movable member 631 from deflecting and allowing the movable member 631 to stably move to the first position or the second position.

[0196] Among them, as in the above embodiment, a limiting column 6315 is protruded from one end of the movable part 631 facing the top wall, a second through hole 615 is opened on the top wall opposite to the first through hole 614, and the limiting column 6315 is inserted into the second through hole 615.

[0197] Please refer to Figures 28 and 29. In some embodiments of the present application, the movable part 631 includes a stop portion 6311 and a plug-in portion 6313 that are connected to each other. The plug-in portion 6313 is passed through the first through hole 614, and the stop portion 6311 is located in the installation 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 opened, and the first trigger member 633 or the first sensing member 635 is provided on the stop portion 6311.

[0198] In this embodiment, the movable part 631 includes a stop portion 6311 and a plug-in portion 6313 connected to each other, and the width of the stop portion 6311 in at least one direction perpendicular to the length direction of the movable part 631 is greater than the width of the plug-in portion 6313 and the first through hole 614 in that direction; it is arranged in this way so that the plug-in portion 6313 is passed through the first through hole 614, and the stop portion 6311 is arranged in the installation cavity 613. When the movable part 631 is not subjected to other external forces, the first reset member 65 applies an outward moving force to the movable part 631, and since the stop portion 6311 cannot pass through the first through hole 614, it abuts against the cavity wall where the first through hole 614 is opened, so that the movable part 631 can be limited to the second position, thereby preventing the movable part 631 from falling out of the installation cavity 613 completely. At this time, by setting the first trigger member 633 or the first sensing member 635 of the sensing module 63 on the stop portion 6311, it can be ensured that the first sensing member 635 or the first trigger member 633 provided on the movable member 631 always remains in the installation cavity 613, preventing the first sensing member 635 or the first trigger member 633 on the movable member 631 from being affected by external foreign objects.

[0199] Referring to FIG. 30 , 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 .

[0200] In this embodiment, a positioning structure 616 is provided in the mounting cavity 613. The positioning structure 616 can demarcate a positioning area 6161 in the mounting cavity 613 for mounting the movable member 631. The positioning area 6161 can be completely enclosed by the positioning structure 616, for example, by providing the positioning structure 616 as a peripheral edge surrounding the movable member 631 or by providing at least two positioning members spaced apart along the circumference of the movable member 631. The positioning area 6161 can also be formed by the positioning structure 616 and the cavity wall of the mounting cavity 613. Placing a portion of the movable member 631 in the positioning area 6161 can also prevent the movable member 631 from deflecting, allowing the movable member 631 to stably move to the first position or the second position, thereby improving the detection accuracy of the position detection module 60.

[0201] Please refer to Figure 29. In some embodiments of the present application, the first sensing member 635 has a transmitting portion 6351 and a receiving portion 6353 arranged opposite to each other, and the first trigger member 633 is a shielding structure; when the movable member 631 moves between the first position and the second position, the first trigger member 633 moves in and out between the transmitting portion 6351 and the receiving portion 6353.

[0202] In this embodiment, the sensing module 63 includes a transmitting part 6351 and a receiving part 6353 arranged opposite to each other. The first trigger part 633 is configured as a shielding structure and can move in and out between the transmitting part 6351 and the receiving part 6353 when the movable part 631 moves between the first position and the second position, so as to shield or hinder the receiving part 6353 from receiving the signal sent by the transmitting part 6351. Among them, the normal state can be that the receiving part 6353 normally receives the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the second position, and the first trigger part 633 is located outside the transmitting part 6351 and the receiving part 6353; the trigger state can be that the receiving part 6353 cannot receive the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the first position, and the first trigger part 633 is separated between the transmitting part 6351 and the receiving part 6353; with such a setting, when the receiving part 6353 cannot 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.

[0203] In addition, the normal state may be that the receiving part 6353 cannot receive the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the second position, and the first trigger part 633 is arranged between the transmitting part 6351 and the receiving part 6353; the trigger state may be that the receiving part 6353 normally receives the signal sent by the transmitting part 6351. At this time, the movable part 631 is in the first position, and the first trigger part 633 is located outside the transmitting part 6351 and the receiving part 6353; with such a setting, 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.

[0204] Among them, the first sensing element 635 can be a photoelectric switch, and the transmitting part 6351 can emit a light signal to the receiving part 6353. For example, the normal state is when the receiving part 6353 can receive the light signal, and the trigger state is when the receiving part 6353 cannot receive the light signal sent by the transmitting part 6351; when the receiving part 6353 cannot normally receive the light signal sent by the transmitting part 6351, the first sensing element 635 generates a sensing signal, indicating that the measured moving structure has moved a preset distance or moved to a preset position.

[0205] In addition, the receiving portion 6353 can also be a Hall sensor, with the transmitting portion 6351 configured as a magnet 53 and the first triggering member 633 configured as a magnetic isolation member. When the first triggering member 633 is positioned between the transmitting portion 6351 and the receiving portion 6353, the Hall sensor cannot sense the magnetic field or the intensity of the sensed magnetic field becomes weaker. A normal state can be defined as when the Hall sensor senses a stronger magnetic field, i.e., when the first triggering member 633 is positioned outside the transmitting portion 6351 and the receiving portion 6353. A triggered state can be defined as when the first triggering member 633 is positioned between the transmitting portion 6351 and the receiving portion 6353 and the intensity of the magnetic field sensed by the Hall sensor becomes weaker or the Hall sensor cannot sense the magnetic field. When the intensity of the magnetic field sensed by the Hall sensor becomes weaker or the Hall sensor cannot sense the magnetic field, the first sensing member 635 generates a sensing signal, indicating that the moving structure under test has moved a preset distance or to a preset position.

[0206] Of course, the first sensing element 635 may also be of other structural types, such as a microwave sensor, etc., which will not be elaborated here.

[0207] 28 and 29 , in some embodiments of the present application, the first triggering member 633 is disposed on the movable member 631 , and the first sensing member 635 is connected to the mounting shell 61 .

[0208] It is understandable that the first sensing element 635 is an electronic device, which usually requires power supply and feedback sensing signals. In some embodiments, the first sensing element 635 can have its own power supply and feedback sensing signals through wireless transmission. In some embodiments, the first sensing element 635 needs to be connected to a wire for receiving electrical energy and feedback sensing signals, or the first sensing element 635 is set on the circuit board 67 in the following embodiment. Therefore, in this embodiment, the first sensing element 635 is fixed in the installation cavity 613, so that the first triggering element 633 is set on the movable element 631 and moves with the movable element 631; such a setting avoids the wire connected to the first sensing element 635 being pulled due to the movement of the first sensing element 635, thereby reducing the risk of wire breakage or damage, improving the stability of the electrical connection of the first sensing element 635, and ensuring the stable performance of the position detection module 60.

[0209] 28 and 29 , in some embodiments of the present application, the position detection module 60 further includes a circuit board 67 . The circuit board 67 is disposed in the mounting cavity 613 . The first sensing element 635 is disposed on the circuit board 67 and electrically connected to the circuit board 67 .

[0210] In this embodiment, the position detection module 60 also includes a circuit board 67 arranged in the installation cavity 613, and the first sensing element 635 is arranged on the circuit board 67 and electrically connected to the circuit board 67. The circuit board 67 can be used to provide electrical energy to the first sensing element 635, and can also be used to process and forward the sensing signal generated by the first sensing element 635; wherein, a power supply can be set on the circuit board 67 to provide the electrical energy required by the circuit board 67 and the first sensing element 635, or the circuit board 67 can be connected to an external power supply; in addition, a wireless communication module can be set on the circuit board 67 for sending and receiving sensing signals, etc.; or the sensing signal can be transmitted by wired communication, which is not limited here.

[0211] 27 and 29 , in some embodiments of the present application, the mounting shell 61 defines a connection port 617 communicating with the mounting cavity 613 , and the circuit board 67 defines a connection seat 671 facing the connection port 617 .

[0212] In this embodiment, a connection port 617 is provided on the mounting housing 61, communicating with the mounting cavity 613. A connector 671 for connecting a power cord and a signal cord is provided on the circuit board 67. The power cord and the signal cord can be integrated into a single conductor. This arrangement allows a conductor or a plug socket paired with the connector 671 to pass through the connection port 617 and connect to the connector 671, thereby providing power to the circuit board 67 and transmitting signals to the circuit board 67.

[0213] Please refer to Figure 31. In some embodiments of the present application, the laser 100 further includes a distance measuring module 70. The distance measuring module 70 is provided on the laser module 20. The distance measuring module 70 is used to detect the distance between the laser module 20 and the processing position.

[0214] In an embodiment of the present application, the laser module 20 is capable of being raised and lowered so that the height of the laser module 20 can be adjusted to process processing positions at different heights. In this embodiment, a distance measuring module 70 is provided in the laser 100. The distance measuring module 70 can be used to detect the distance between the focus of the laser module 20 and the surface of the processing object. Among them, the distance measuring module 70 can be an ultrasonic distance measuring structure, a photoelectric distance measuring structure, a laser distance measuring structure, or a contact distance measuring structure. Ultrasonic distance measuring, photoelectric distance measuring, and laser distance measuring can respectively use the propagation time of sound waves, infrared light, and laser to convert the distance. The contact distance measuring structure can measure the descending distance of the distance measuring module 70 until it contacts the processing position to convert the distance.

[0215] Please refer to Figures 31 to 37. In some embodiments of the present application, the ranging module 70 includes a shell 71, a circuit board 72, a ejector pin 73 and a detection mechanism 74. The shell 71 is provided with a accommodating cavity 713 and a first opening and a second opening connected to the accommodating cavity 713; the circuit board 72 is covered by the first opening; the ejector pin 73 is lifted and passed through the second opening and is partially located in the accommodating cavity 713. The ejector pin 73 has a starting position and a trigger position located above the starting position; the detection mechanism 74 is provided in the accommodating cavity 713, and the detection mechanism 74 includes a second triggering member 741 and a second sensing member 742. The second triggering member 741 is connected to the ejector pin 73. The second sensing member 742 is provided on the surface of the circuit board 72 facing the accommodating cavity 713 and is electrically connected to the circuit board 72; wherein, when the ejector pin 73 is in the triggering position, the second triggering member 741 triggers the second sensing member 742.

[0216] In this embodiment, the distance measuring module 70 is located to the side of the laser module 20 and is arranged near the light outlet 23, so that the distance between the position to be processed below the light outlet 23 and the laser module 20 can be measured more accurately. The distance measuring module 70 is composed of a shell 71, a circuit board 72, a pin 73 and a detection mechanism 74. The shell 71 is provided with a accommodating cavity 713. The side wall of the shell 71 is provided with a first opening connected to the accommodating cavity 713, and the bottom wall of the shell 71 is provided with a second opening connected to the accommodating cavity 713; the circuit board 72 is covered in the first opening, and the surface of the circuit board 72 exposed in the accommodating cavity 11 can be provided with a terminal block 721 for connecting to a power supply and a control system, etc.; the pin 73 extends along the lifting direction of the laser module 20 and passes through the second opening at the bottom of the accommodating cavity 713, so that the pin 73 can be raised and lowered relative to the shell 71, and has a starting position and a trigger position located above the starting position. The detection mechanism 74 is disposed within the accommodating chamber 11. A second triggering member 741 of the detection mechanism 74 is connected to the ejector pin 73. A second sensing member 742 of the detection mechanism 74 is disposed on the circuit board 72 and electrically connected thereto, thereby preventing contamination of the detection mechanism 74 by smoke and oil during the machining process. The second triggering member 741 of the detection mechanism 74 is connected to a portion of the ejector pin 73 inserted within the accommodating chamber 713, allowing the ejector pin 73 to switch between a starting position and a triggering position as the ejector pin 73 rises and falls. Without being subject to any external forces, the ejector pin 73 can droop to its starting position under its own gravity or under the action of a second return member (described below). When distance measurement is required, the laser module 20 is controlled to descend, causing the distance measurement module 70 to descend with it. After the ejector pin 73 contacts the location to be machined, the laser module 20 and the distance measurement module 70 are further lowered, causing the ejector pin 73 to retract into the accommodating chamber 713 until it reaches the triggering position. The second triggering member 741 triggers the second sensing member 742. After the second sensing member 742 generates a sensing signal, it can be transmitted to the control system through the circuit board 72. At this time, it is only necessary to know the distance between the lower end face of the ejector pin 33 and the laser focus or the light outlet of the laser module 20 in this state, and by obtaining the descending distance of the laser module 20, the distance between the focus of the laser module 20 and the position to be processed can be calculated. After triggering the second sensing member 742, the laser module 20 can be controlled to move upward for a fixed distance. This distance is the distance between the lower end face of the ejector pin 73 of the ranging module 70 and the focus of the laser module 20 when the ejector pin 73 is in the trigger position, thereby ensuring that the focus of the laser module 20 falls on the position to be processed and improving the processing accuracy. Among them, the descending distance of the laser 100 or the laser module 20 can be obtained according to the working distance of the driving parts such as the motor or cylinder that drives the laser 100 or the laser module 20 to rise and fall.

[0217] The second sensing element 742 can be configured as a Hall effect sensor, a photoelectric switch, a proximity switch, a grating readout head, or the like. For example, if the second sensing element 742 is a Hall effect sensor and the second triggering element 741 is configured as a magnet, as the second triggering element 741 moves with the ejector pin 73 between the trigger position and the starting position, the magnetic field strength surrounding the Hall effect sensor changes, for example, from weak to strong or from strong to weak. Using the magnetic field strength detected by the Hall effect sensor when the second triggering element 741 is in the trigger position as the trigger condition, the Hall effect sensor can emit a sensing signal when the second triggering element 741 reaches the trigger position. If a proximity switch is used as the second sensing element 742, the second triggering element 741 can contact the sensing surface of the proximity switch when the ejector pin 73 is in the trigger position, causing the proximity switch to emit a sensing signal. If a grating reading head is used as the second sensing element 742, and the second triggering element 741 is a scale grating extending along the movable direction of the ejector pin 73, when the ejector pin 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 relative to the scale grating and convert the displacement into an electrical signal. The signal processing circuit processes the displacement data, thereby generating a sensing signal when the second triggering element 741 moves a corresponding distance from the starting position to the triggering position. The use of other structures as the detection mechanism 74 is not detailed here.

[0218] Optionally, the housing 71 is provided with a limiting notch 719 , and at least a portion of the structure of the circuit board 72 is provided in the limiting notch 719 to limit the circuit board 72 and improve the installation stability of the circuit board 72 .

[0219] Please refer to Figure 34. In some embodiments of the present application, the ranging module 70 further includes a second reset member, which is disposed in the accommodating cavity 713 and acts between the shell 71 and the ejector pin 73 to cause the ejector pin 73 to tend to remain in the starting position.

[0220] In this embodiment, a second reset element is provided in the distance measurement module 70. The second reset element can be an elastic element such as a spring, a gas spring, or an elastic airbag. The elastic element can be provided on the side of the top wall opposite the second opening and apply an elastic thrust toward the second opening to the ejector pin 73, causing the ejector pin 73 to have a tendency to move from the trigger position to the response position and remain in the response position. The elastic element can 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, similarly causing the ejector pin 73 to have a tendency to move from the trigger position to the response position and remain in the response position. The second reset element can also be a magnetic structure, which can include a first magnetic element and a second magnetic element provided on the ejector pin 73 and the housing 71, respectively. A magnetic attraction can exist between the first magnetic element and the second magnetic element, causing the ejector pin 73 to have a tendency to move from the trigger position to the response position and remain in the response position. A magnetic repulsion can also exist between the first magnetic element and the second magnetic element, causing the ejector pin 73 to have a tendency to move from the trigger position to the response position and remain in the response position. When ejector pin 73 is moved into mounting cavity 613 by an external force, the force applied by the second return member is overcome. When the external force on ejector pin 73 is removed, the force applied by the second return member to ejector pin 73 causes ejector pin 73 to move to the response position. This arrangement ensures that ejector pin 73 remains stably in its starting position when it is not needed to support the workpiece. It also applies a downward force to ejector pin 73, preventing it from bouncing upward due to the reaction force upon initial contact with the workpiece, potentially triggering second sensing element 742.

[0221] Referring to Figures 34 and 35 , 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 and fixed to the ejector pin 73, and the trigger portion 7412 is connected to the end of the fixing portion 7411 near the circuit board 72 and extends upward. This arrangement allows the installation location of electronic components such as the circuit board 72 to be as far away as possible from the light outlet 23 of the laser module 20, and thus away from the processing location and the laser. This prevents dust and other impurities from adhering to the electronic components such as the circuit board 72, and also prevents heat generated during the processing from affecting the performance of the electronic components.

[0222] Referring to Figure 35 , in some embodiments of the present application, the second trigger member 741 is provided with a screw hole 7413, and at least a portion of the outer surface of the ejector pin 73 is provided with external threads. The screw hole 7413 cooperates with the external threads to threadably connect the second trigger member 741 to the ejector pin 73. This arrangement facilitates assembly and disassembly between the second trigger member 741 and the ejector pin 73, and allows adjustment of the installation height of the second trigger member 741 on the ejector pin 73, thereby adjusting the distance between the starting position and the trigger position of the ejector pin 73 to meet different processing requirements.

[0223] Please refer to Figures 33 to 35. In some embodiments of the present application, the shell 71 includes a base 711 and a dust seat 712. A first accommodating space 7131 is formed in the base 711. The side wall of the base 711 is provided with a connecting port 714 connected to the first accommodating space 7131. The dust seat 712 is covered on the outer wall of the base 711 provided with the connecting port 714. A second accommodating space 7132 is formed in the dust seat 712. The second accommodating space 7132 is connected with the first accommodating space 7131 to form an accommodating cavity 713. The dust seat 712 is provided with a first opening on the side facing away from the base 711, and the base 711 is provided with a second opening; the ejector pin 73 is inserted into the first accommodating space 7131, and the second trigger member 741 passes through the connecting port 714 from the first accommodating space 7131 and extends to the second accommodating space 7132.

[0224] Please refer to Figures 32 and 34. In some embodiments of the present application, the dust seat 712 is provided with an extension portion 716 protruding from the top of the base 711. The extension portion 716 is covered on the side of the laser module 20. A dust cavity 717 and a avoidance port connected to the dust cavity 717 are provided in the extension portion 716. The avoidance port and the first opening are located on the same side of the dust seat 712. The circuit board 72 is covered in the avoidance port. Some components on the circuit board 72 are located on the surface of the circuit board 72 facing the dust cavity 717.

[0225] In this embodiment, the dustproof base 712 includes a main body mounted on the side of the base 711 and an extension 716 protruding from the top of the base 711. The circuit board 72 is mounted on the surface of the dustproof portion 361 facing away from the base 711, with a portion of the circuit board 72 mounted on the extension 716. A dustproof cavity 717 and a relief opening communicating with the dustproof cavity 717 are defined within the extension 716. The relief opening and the first opening are located on the same side. The circuit board 72 is mounted on the relief opening, so that some components mounted on the circuit board 72 are disposed within the dustproof cavity 717. This protects the components and prevents them from being contaminated by impurities such as dust and oil, which could affect their performance.

[0226] Optionally, the dustproof cavity 717 and the second accommodating space 7132 may be communicated with each other; optionally, the avoidance port and the first opening may be configured as an integrated opening, or may be two independent openings.

[0227] In some embodiments, a first heat sink 42 or a second heat sink 43 is disposed on a side of the laser module 20 . In this case, the extension portion 716 may cover a surface of the first heat sink 42 or the second heat sink 43 .

[0228] Please refer to Figures 31 and 32. In some embodiments of the present application, the surface of the extension portion 716 facing the laser module 20 is provided with one of the limiting groove 432 and the limiting protrusion 718, and the side of the laser module 20 is provided with the other of the limiting groove 432 and the limiting protrusion 718, and the limiting protrusion 718 is inserted into the limiting groove 432.

[0229] In this embodiment, a limiting protrusion 718 can be provided on the extension portion 716, and a limiting groove 432 can be provided on the side of the laser module 20. Alternatively, the limiting protrusion 718 can be provided on the side of the laser module 20, and the limiting groove 432 can be provided on the extension portion 716. When the ranging module 70 is installed, the limiting protrusion 718 is inserted into the limiting groove 432, thereby improving the connection strength between the ranging module 70 and the laser module 20 and limiting the ranging module 70, preventing the ranging module 70 from being displaced by external forces and affecting detection accuracy.

[0230] It should be noted that, in this embodiment, the limiting protrusion 718 or the limiting groove 432 can be directly set on the side wall of the laser module 20, or the limiting protrusion 718 or the limiting groove 432 can be set on the first heat sink 42 or the second heat sink 43 installed on the side of the laser module 20, which is not limited here.

[0231] Referring to Figures 33 and 34 , in some embodiments of the present application, a receiving hole 715 is defined in the top wall of the accommodating cavity 713. This receiving hole 715 is positioned opposite one end of a pin 73 inserted into the accommodating cavity 713, and the pin 73 can be inserted into the receiving hole 715. This arrangement allows the pin 73 to be inserted into the receiving hole 715 at least during its ascent. This eliminates the need to adjust the height of the accommodating cavity 713 to match the pin 73, thus reducing the size of the ranging module 70. Furthermore, the provision of the receiving hole 715 serves as a guide and position limiter for the pin 73, preventing it from being trapped during its ascent. Alternatively, the pin 73 can be inserted into the receiving hole 715 only after it has risen to a certain height, or it can be permanently inserted into the receiving hole 715, without limitation.

[0232] Referring to FIG. 16 , in some embodiments of the present application, a conductive structure 17 is provided on the side wall of the housing 10 , and the laser module 20 is electrically connected to the conductive structure 17 .

[0233] In this embodiment, when the laser 100 is applied to the laser device 1, it is electrically connected to the device body 200 through the conductive structure 17 provided on the side wall of the shell 10 to supply power to the laser module 20 inside the shell 10; with this arrangement, there is no need to set a wire to connect the external power supply of the laser 100 and the laser module 20, so as to avoid the wire between the external power supply and the laser module 20 affecting the lifting and lowering of the laser module 20, and there is no need to set a wire connection between the laser 100 and the device body 200. The conductive structure 17 is set as one of the male and female sockets, and the other of the male and female sockets is set at the installation position of the laser 100 on the laser device 1. An electrical connection relationship can be formed by docking the male and female sockets, thereby reducing the use of wires and making the overall structure of the laser device 1 neater.

[0234] Referring to FIG. 22 , in some embodiments of the present application, an adapter plate 80 is provided in the accommodating cavity 11 . The adapter plate 80 may be a circuit board 72 or simply a conductive device. The conductive structure 17 is provided through the side wall of the housing 10 and electrically connected to the adapter plate 80 . The laser module 20 and other electronic components in the accommodating cavity 11 can then be electrically connected to the adapter plate 80 , which then supplies power to the various electronic components. The adapter plate 80 can also be used to receive, process, and transmit data signals and control signals, thereby enabling information exchange between the laser 100 and the device body 200 .

[0235] In addition, a connecting structure 16 can be provided on the side wall of the housing 10 for fixing the laser 100 to the device body 200 of the laser device 1. The installation method of the laser 100 can be plug-in, snap-on connection, bolt connection, magnetic connection, etc., which is not limited here. At this time, the laser 100 can be electrically connected at the same time when it is installed on the device body 200, thereby improving the convenience of installation. In some embodiments, a gas nozzle module 50 is provided in the laser 100, and a mounting port 13 is opened on the housing 10 of the laser 100 for connecting to the gas source. At this time, an air outlet can be provided on the device body 200, so that when the laser 100 is installed on the device body 200, the air outlet and the mounting port 13 are directly arranged relative to each other and connected.

[0236] Referring to FIG. 1 , the present application further provides a laser device 1 comprising a device body 200 and a laser 100 as in any of the aforementioned embodiments. The laser device 1 may be a laser engraver, a laser marking machine, a laser cutting machine, or the like. The device body 200 of the laser device 1 may be a frame, with the laser 100 being fixed to the device body 200 via a housing 10. Alternatively, a translation assembly 230 may be provided on the device body 200, with the laser 100 being fixed to the translation assembly 230, thereby enabling the laser 100 to be translated to different processing positions.

[0237] Since the laser device 1 proposed in this application applies all the technical solutions of all the aforementioned embodiments, it at least has all the beneficial effects brought about by all the aforementioned technical solutions, which will not be described one by one here.

[0238] Please refer to Figures 16, 38 and 39. In some embodiments of the present application, the housing 10 of the laser 100 is provided with a mounting port 13 connected to the accommodating cavity 11. The laser 100 also includes an air inlet connector 90 connected to the air guide channel 514. The air inlet connector 90 is provided at the mounting port 13. When the laser 100 is provided on the mounting surface, the air inlet connector 90 and the air path interface 21b are connected to each other.

[0239] In this embodiment, a nozzle module 50 is provided in the laser 100. The nozzle module 50 is housed outside the light outlet 23 of the laser module 20 and is provided with an air guide channel 513, a flow guide cavity 521, and an outlet 522, which are sequentially connected. The light outlet 23 is located in the flow guide 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. In addition, a mounting port 13 is provided on the housing 10 of the laser 100. The mounting port 13 is installed with an air inlet connector 90, and an air guide hose 55 is provided in the accommodating cavity 11. The air guide hose 55 can be bent and deformed as needed. The air guide hose 55 can be made of plastic, rubber, PVC (polyvinyl chloride), PE (polyethylene), PP (polypropylene), etc. One end of the air guide hose 55 is connected to the air inlet connector 90, and the other end of the air guide hose 55 is connected to the air guide channel 513 of the nozzle module 50.

[0240] The laser device 1 has a main body 200, a back plate 210 for mounting the laser 100. One side of the back plate 210 serves as a mounting surface for mounting 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 mounting surface of the back plate 210. The air inlet channel 21a can extend through both sides of the back plate 210, and the opening at the other end of the air inlet channel 21a, facing away from the mounting surface, can be connected to an air supply structure 300, such as an air pump. When the laser 100 is mounted on the mounting surface of the back plate 210, the mounting opening 13 provided on the side wall of the laser 100 housing 10 and the air path interface 21b on the mounting surface are arranged opposite each other and communicate with each other, thereby allowing the laser 100 to communicate with the air supply structure 300, such as an air pump, through the air inlet channel 21a. Such an arrangement allows the installation of the laser 100 and the operation of connecting the gas to the laser 100 to be carried out simultaneously. The gas path is connected when the laser 100 is installed, and there is no need to connect the gas before or after the installation of the laser 100, thereby improving the convenience of disassembly and assembly of the laser 100.

[0241] During laser processing, the air supply structure 300 such as the air pump drives the air flow from the air inlet channel 21a and the mounting port 13 into the air nozzle module 50, and the air flow is blown out from the outlet 522 through the guide cavity 521; in this way, the dust and smoke outside the outlet 522 can be blown away, and the continuous air flow can also prevent dust and other impurities from entering the guide cavity 521 and entering the light outlet 23 of the laser module 20 or adhering to the window mirror or focusing mirror, thereby avoiding affecting the laser emission.

[0242] 39 and 40 , in some embodiments of the present application, a sealing ring 21 d is sandwiched between the laser 100 and the back plate 210 , and the sealing ring 21 d is disposed around the circumference of the gas path interface 21 b .

[0243] In this embodiment, a sealing ring 21d is provided between the laser 100 and the back plate 210, and the sealing ring 21d is arranged around the circumference of the gas path interface 21b. The sealing ring 21d can be made of an elastic material such as rubber, silicone, or silicon rubber, so that when the laser 100 and the back plate 210 clamp the sealing ring 21d, the sealing ring 21d can be elastically deformed and respectively adhered to the back plate 210 and the laser 100, so that a sealed cavity is formed between the sealing ring 21d, the laser 100, and the back plate 210, thereby improving the sealing between the mounting port 13 and the gas path interface 21b and avoiding the problem of air leakage. Among them, the sealing ring 21d can be fixed on the back plate 210, or it can be fixed on the housing 10 of the laser 100, which is not limited here.

[0244] Please refer to Figure 40. In some embodiments of the present application, a fixing groove 21f is recessed on the mounting surface, the mounting opening 13 is opened on the bottom wall of the fixing groove 21f, and the sealing ring 21d is arranged in the fixing groove 21f and protrudes from the mounting surface.

[0245] In this embodiment, the sealing ring 21d is fixed to the back plate 210 of the device body 200. Therefore, when other lasers 100 need to be replaced, it is not necessary to set the sealing ring 21d on each laser 100, thereby reducing the use of the sealing ring 21d. Among them, the mounting surface of the back plate 210 is concavely provided with a fixing groove 21f, so that the gas path interface 21b is opened on the bottom wall of the fixing groove 21f, and the sealing ring 21d is installed in the fixing groove 21f and arranged around the gas path interface 21b. The fixing groove 21f is used to limit the sealing ring 21d, thereby preventing the sealing ring 21d from being offset and unable to surround the gas path interface 21b and the outer periphery of the mounting opening 13. In addition, a portion of the sealing ring 21d protrudes from the fixing groove 21f, thereby ensuring that when the laser 100 is mounted on the mounting surface, the laser 100 can abut against the sealing ring 21d, thereby achieving better sealing performance.

[0246] Please refer to Figures 39 and 40. In some embodiments of the present application, the device body 200 further includes a locking member 21e, which fixes the sealing ring 21d to the back plate 210.

[0247] In this embodiment, a locking member 21e is provided on the device body 200. This locking member 21e acts between the back plate 210 and the sealing ring 21d to secure the sealing ring 21d to the back plate 210. The locking member 21e can be an adhesive structure, such as glue, double-sided tape, or Velcro; it can also be a removable structure, such as a screw or a pressing member configured to press against the outer or inner ring of the sealing ring 21d. Using the locking member 21e to secure the sealing ring 21d improves the connection strength between the sealing ring 21d and the back plate 210 and reduces the risk of the sealing ring 21d falling off or becoming misaligned.

[0248] Please refer to Figure 40. In some embodiments of the present application, the locking member 21e includes a locking portion 211e and a crimping portion 212e that are connected to each other. The cross-sectional size of the crimping portion 212e is larger than the cross-sectional size of the locking portion 211e. The locking member 21e is also provided with an air outlet 213e that passes through the locking portion 211e and the crimping portion 212e; the inner ring of the sealing ring 21d is convexly provided with a buttress 211d, the locking portion 211e is passed through the sealing ring 21d and inserted into the air path interface 21b and fixedly connected to the back plate 210, and the crimping portion 212e presses the buttress 211d onto the back plate 210.

[0249] In this embodiment, the locking member 21e is used to press the sealing ring 21d onto the back plate 210; specifically, the locking member 21e includes a locking portion 211e and a pressing portion that are connected to each other. The locking portion 211e can be passed through the sealing ring 21d and inserted into the air path interface 21b, and is connected and fixed to the back plate 210; and the crimping portion 212e is arranged on the outside of the air path interface 21b; an abutment portion 211d is provided on the inner ring of the sealing ring 21d, and the abutment portion 211d can be arranged around the inner ring of the sealing ring 21d, or can be arranged at a partial position of the inner ring, for example, at least two abutment portions 211d arranged at intervals are provided along the inner ring; when the locking portion 211e of the locking member 21e is inserted into the air path interface 21b, the crimping portion 212e of the locking member 21e is pressed on the abutment portion 211d of the sealing ring 21d, so that the sealing ring 21d can be pressed and fixed to the back plate 210. At the same time, the locking member 21e needs to have an air outlet 213e that passes through the locking portion 211e and the crimping portion 212e to avoid blocking the air path interface 21b. The locking portion 211e of the locking member 21e and the air path interface 21b can be an interference fit, or can be bonded or threaded, etc., which is not limited here.

[0250] The locking member 21e of the present embodiment is used to fix the sealing ring 21d, and the locking member 21e can be hidden inside the sealing ring 21d, thereby preventing the laser 100 from abutting against the locking member 21e when the laser 100 is fixed to the back plate 210, thereby preventing the laser 100 from being scratched by the locking member 21e or preventing the laser 100 from being able to stick tightly to the sealing ring 21d.

[0251] Please refer to FIG. 39 . In some embodiments of the present application, the other end of the air inlet channel 21 a away from the air path interface 21 b opens on the top surface of the back plate 210 .

[0252] In this embodiment, the opening of one end of the air inlet channel 21a for connecting to the air supply structure 300 is opened on the top surface of the back plate 210. In this way, the air pipe 220 connecting the air supply structure 300 and the air inlet channel 21a can be connected to the top of the back plate 210, which can be away from the processing position and the laser and facilitate the connection of the air pipe 220.
