Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a refrigerated dryer, a gas supply system, and a laser processing system. Background Technology

[0002] During laser processing operations such as laser cutting, auxiliary gas is typically supplied to the cutting position to blow away waste and cool the cutting surface. Laser processing systems usually use compressed air from an air compressor as the auxiliary gas for laser cutting. However, the temperature of the compressed air is relatively high. In related technologies, a refrigerated dryer is usually installed to cool the compressed air discharged from the air compressor and filter impurities. However, after the air compressor has been running for a long time, the temperature of the discharged gas becomes too high. If this high-temperature gas enters the refrigerated dryer, it can easily overload the cooling components in the dryer, affecting the cooling effect on the gas. Utility Model Content

[0009] In one embodiment, the inlet of the refrigerant flow path is connected to the airflow outlet of the third flow channel;

[0010] And / or, the refrigerant flow path and the first flow channel are arranged in a double helix structure in the first cooling assembly.

[0013] In one embodiment, the filtration assembly includes a first filter, a second filter, and a third filter connected in sequence. The first filter is configured to remove oil, dust, and moisture from the airflow, and at least one of the second filter and the third filter is configured to remove oil and dust from the airflow.

[0015] And / or, the filter element of the second filter comprises at least one of glass fiber and activated carbon;

[0016] And / or, the filter element of the third filter comprises at least one of glass fiber and activated carbon.

[0017] In one embodiment, the filtration accuracy of at least two of the filters increases along the flow direction of the airflow in the third flow channel;

[0018] And / or, the filter assembly may also include a drain pipe.

[0019] In one embodiment, the refrigerated dryer further includes a mounting housing with a mounting cavity, in which the first cooling component, the second cooling component, and the filter component are all disposed.

[0020] In one embodiment, the mounting housing is provided with a vent hole that connects the mounting cavity to the external environment;

[0024] This application also proposes an air supply system for use in a laser processing system. The air supply system includes an air compressor and a refrigerated dryer as described in any of the foregoing embodiments, wherein the air outlet of the air compressor is connected to the airflow inlet of the refrigerated dryer.

[0025] This application also proposes a laser processing system, including a gas supply system as described in any of the foregoing embodiments.

[0026] In one embodiment, the laser processing system further includes:

[0029] The technical solution of this utility model includes a first cooling component, a second cooling component, and a filter component connected in sequence in a refrigerated dryer. Airflow passes sequentially through the first channel of the first cooling component, the second channel of the second cooling component, and the third channel of the filter component. Airflow is pre-cooled in the first cooling component and then undergoes secondary cooling in the second cooling component. The use of two sets of cooling components increases the number of cooling cycles and the cooling time of the airflow in the refrigerated dryer, achieving stepped cooling and effectively cooling the airflow. Furthermore, the first cooling component does not need to cool the airflow to the final required temperature, resulting in relatively low refrigeration pressure. In the second cooling component, since the airflow has already been pre-cooled by the first cooling component, the refrigeration pressure of the second cooling component is also relatively low, preventing overload and ensuring the normal operation of the second cooling component.

[0030] The airflow from the second cooling component then flows through the filter component to remove oil, dust, and moisture. After two cooling cycles, the airflow is cooled to a lower temperature, which allows the moisture in the airflow to condense and be fully absorbed by the filter component. This ensures that the temperature, dryness, and cleanliness of the airflow discharged from the refrigerated dryer meet the usage requirements. Attached Figure Description

[0046] During laser processing operations such as laser cutting, auxiliary gas is typically supplied to the cutting position to blow away molten slag and cool the cutting surface. Laser processing systems usually use compressed air from an air compressor as the auxiliary gas for laser cutting. However, the temperature of the compressed air is relatively high. In related technologies, a refrigerated dryer is usually installed to cool the compressed air discharged from the air compressor and filter impurities. However, after the air compressor has been running for a long time, the temperature of the discharged gas becomes too high. If this high-temperature gas enters the refrigerated dryer, it can easily overload the cooling components in the dryer, affecting the cooling effect on the gas.

[0047] Based on the above considerations, this application proposes a refrigerated dryer 100, which can effectively cool the gas discharged from the air compressor.

[0048] Please see Figure 1 In some embodiments of this application, the refrigerated dryer 100 includes a first cooling component 10, a second cooling component 20, and a filter component 30. The first cooling component 10 has a first flow channel 11; the second cooling component 20 has a second flow channel 21, which is connected to the first flow channel 11; the filter component 30 has a third flow channel 31, which is connected to the second flow channel 21. The filter component 30 is used to filter out at least one of oil, dust, and moisture in the airflow.

[0049] The refrigerated air dryer 100 proposed in this application includes a first cooling component 10, a second cooling component 20, and a filter component 30 connected in sequence. After the airflow enters the refrigerated air dryer 100, it flows through the first flow channel 11 of the first cooling component 10, the second flow channel 21 of the second cooling component 20, and the third flow channel 31 of the filter component 30 in sequence. It can be used to cool and filter the airflow so that the temperature and cleanliness of the airflow discharged from the refrigerated air dryer 100 meet the usage requirements.

[0050] The first cooling component 10 can be configured as a heat exchange module as described in the following embodiment. The heat exchange module includes a first flow channel 11 and a refrigerant flow channel. The refrigerant flowing through the refrigerant flow channel can be either a liquid or a gas. When the refrigerant passes through the refrigerant flow channel, it can exchange heat with the airflow flowing through the first flow channel 11 via the heat exchange module, thereby cooling the airflow in the first flow channel 11. Optionally, the refrigerant flowing through the refrigerant flow channel can also be a gas that has undergone secondary cooling by the second cooling component 20; this is not limited to this. Of course, the first cooling component 10 can also be configured as, but is not limited to, an air-cooled heat dissipation refrigeration component, a semiconductor refrigeration component, etc.

[0051] The second cooling component 20 can be configured as a semiconductor refrigeration component, a compressor refrigeration component, an evaporator, etc. When the airflow flows through the second flow channel 21, it can be subjected to secondary cooling by the second cooling component 20. Since the airflow has been pre-cooled by the first cooling component 10, the refrigeration pressure of the second cooling component 20 is relatively small, which can avoid overload of the second cooling component 20 and ensure its normal operation. At this time, the airflow temperature is relatively low, which can also cause the moisture in the airflow to condense, thereby removing the moisture in the airflow initially and also facilitating the subsequent filtration component 30 to better filter the moisture in the airflow.

[0052] The filter assembly 30 is used to filter the airflow, removing at least one of the following impurities: oil, dust, and moisture. In some embodiments, some moisture can also be removed from the airflow as it passes through the filter assembly 30. The filter assembly 30 may include only one filter, which simultaneously achieves dust removal, oil removal, and water removal. Alternatively, the filter assembly 30 may include two or more filters, such as an oil mist filter, a dust filter, and a dryer. At least one filter may simultaneously achieve at least two of the three filtration effects: dust removal, oil removal, and water removal. For example, the first-stage filter may be used for dust removal, oil removal, and water removal, and may be a porous membrane. The second-stage filter may be used for dust removal and oil removal, and may be a fiberglass filter, an activated carbon filter, or a combination of fiberglass and activated carbon. Optionally, the filter assembly 30 may also include filters such as screens, electrostatic precipitators, and cyclone separators; these are not limited here.

[0053] In other words, the technical solution of this application sets up a first cooling component 10, a second cooling component 20, and a filter component 30 connected in sequence in the refrigerated dryer 100. The airflow flows through the first flow channel 11 of the first cooling component 10, the second flow channel 21 of the second cooling component 20, and the third flow channel 31 of the filter component 30 in the refrigerated dryer 100. It can be pre-cooled in the first cooling component 10 and then undergo a second cooling process in the second cooling component 20. By setting up two sets of cooling components, the number of cooling times and the cooling time of the airflow in the refrigerated dryer 100 are increased, realizing stepped cooling and effectively cooling the airflow. Moreover, the first cooling component 10 does not need to cool the airflow to the final required temperature, and the refrigeration pressure is relatively small. In the second cooling component 20, since the airflow has been pre-cooled by the first cooling component 10, the refrigeration pressure of the second cooling component 20 is also relatively small, which can avoid overload of the second cooling component 20 and ensure the normal operation of the second cooling component 20. The airflow from the second cooling component 20 then flows through the filter component 30 to remove oil, dust and moisture. After two cooling cycles, the airflow is cooled to a lower temperature, which allows the moisture in the airflow to condense and be fully absorbed by the filter component 30. This ensures that the temperature, dryness and cleanliness of the airflow discharged from the refrigerated dryer 100 meet the usage requirements.

[0054] Please see Figure 1 and Figure 5 In some embodiments of this application, a refrigerant flow path 12 is provided in the first cooling assembly 10.

[0055] In this embodiment, the first cooling component 10 is configured as a heat exchange module. The first cooling component 10 is provided with a first flow channel 11 and a refrigerant flow channel. The refrigerant flowing through the refrigerant flow channel can be a liquid or a gas. When the refrigerant passes through the refrigerant flow channel, it can exchange heat with the airflow flowing through the first flow channel 11 through the heat exchange module to cool the airflow in the first flow channel 11. Optionally, the refrigerant flowing through the refrigerant flow channel can also be a gas that has been cooled twice by the second cooling component 20.

[0056] Please see Figure 1 In some embodiments of this application, the inlet of the refrigerant flow path 12 is connected to the airflow outlet of the third flow channel 31.

[0057] In this embodiment, the airflow outlet of the third flow channel 31 in the filter assembly 30 is connected to the inlet of the refrigerant flow path 12. That is, the airflow flowing out of the third flow channel 31 enters the refrigerant flow path 12, allowing it to exchange heat with the airflow in the first flow channel 11 through the first cooling assembly 10, thereby achieving pre-cooling treatment of the airflow in the first flow channel 11. The first cooling assembly 10 is configured in this application to achieve pre-cooling, preventing overload of the second cooling assembly 20 and ensuring its normal operation. The second cooling assembly 20 has high cooling efficiency, causing the temperature of the airflow after two cooling cycles to drop to a lower temperature range. For example, in practical applications where the required airflow temperature is between 15°C and 25°C, the airflow temperature after two cooling cycles reaches 5°C to 10°C. At this point, even if the gas flowing out of the third flow channel 31 first acts as a refrigerant in the first cooling assembly 10 to absorb some of the heat from the airflow in the first flow channel 11, the airflow temperature will not rise to a high range, and the airflow discharged from the refrigerated dryer 100 can still meet the usage requirements. By using the airflow after two cooling cycles and filtration as the refrigerant in the first cooling component 10, the airflow is recycled, improving energy efficiency. Furthermore, it eliminates the need for an additional refrigerant circulation component, which simplifies the structure of the refrigerated dryer 100 and enables its miniaturization and lightweight design.

[0058] Please see Figure 1 In some embodiments of this application, the refrigerant flow path 12 and the first flow channel 11 are arranged in a double helix structure in the first cooling assembly 10.

[0059] In this configuration, the refrigerant flow path 12 and the first flow channel 11 have a relatively long heat exchange distance in the first cooling assembly 10, which can effectively pre-cool the airflow in the first flow channel 11.

[0060] In some embodiments of this application, the second cooling assembly 20 includes at least one of a semiconductor cooling assembly and a compressor cooling assembly.

[0061] In this embodiment, the second cooling component 20 can be configured as a semiconductor refrigeration component, a compressor refrigeration component, or both. This configuration allows the airflow to be effectively cooled within the second cooling component 20.

[0062] Please see Figure 1 and Figure 3 In some embodiments of this application, the filter assembly 30 includes at least two filters that are sequentially connected along the third flow channel 31.

[0063] In this embodiment, the filter assembly 30 is provided with two or more filters, which can perform multi-stage filtration of the airflow; for example, an oil mist filter, a dust filter, and a dryer are respectively provided, and the corresponding filters achieve the effects of oil removal, dust removal, and water removal. In addition, at least one of the filters can simultaneously achieve at least two of the filtration effects of dust removal, oil removal, and water removal. For example, the first filter is used for dust removal, oil removal, and water removal, and is set as a porous filter membrane; the second filter is used for dust removal and oil removal, and can be set as a glass fiber filter, activated carbon filter, or a combination of glass fiber and activated carbon filter, etc. Optionally, the filter assembly 30 may also include a third filter, which can be used to achieve at least one of the filtration effects of dust removal and oil removal.

[0064] Please see Figure 1 and Figure 3 In some embodiments of this application, the filter assembly 30 includes a first filter 32, a second filter 33, and a third filter 34 connected in sequence. The first filter 32 is configured to filter out oil, dust, and moisture in the airflow, and at least one of the second filter 33 and the third filter 34 is configured to filter out oil and dust in the airflow.

[0065] In this configuration, after the first filter 32 removes moisture, oil, and dust from the airflow, the airflow becomes relatively dry. The second filter 33 and the third filter 34 then perform a second or even third removal of oil and dust, achieving step-by-step filtration and reducing the workload on the second and third filters 33 and 34. Optionally, the filtration precision of the first filter 32, second filter 33, and third filter 34 can be progressively increased, gradually removing impurities of different sizes and achieving a better filtration effect.

[0066] In some embodiments of this application, the first filter 32 is provided with a filter membrane; wherein, the pore size of the filter membrane can be set as needed, for example, it can be set to 1 micrometer, 2 micrometer, 0.1 micrometer or other sizes, and is not limited herein. Optionally, multiple filter membranes can be provided, for example, multiple filter membranes can be sintered together to form a composite. The filter membrane can effectively filter out moisture, oil and dust in the airflow.

[0067] In some embodiments of this application, the filter element of the second filter 33 comprises at least one of glass fiber and activated carbon.

[0068] Among them, glass fiber filter elements can effectively intercept oil and dust in the airflow, thereby removing oil and dust from the airflow; activated carbon can adsorb organic compounds in the airflow. In some embodiments, a filter element structure formed by combining glass fiber and activated carbon can be used, for example, by sintering glass fiber and activated carbon into an integrated filter element, which can have better dust removal, oil removal, and odor removal capabilities.

[0069] In some embodiments of this application, the filter element of the third filter 34 comprises at least one of activated carbon and glass fiber.

[0070] Among them, glass fiber filter elements can effectively intercept oil and dust in the airflow, thereby removing oil and dust from the airflow; activated carbon can adsorb organic compounds in the airflow. In some embodiments, a filter element structure formed by combining glass fiber and activated carbon can be used, for example, by sintering glass fiber and activated carbon into an integrated filter element, which can have good dust removal, oil removal, and odor removal capabilities.

[0071] In some embodiments of this application, the filtration accuracy of at least two filters increases along the flow direction of the airflow in the third flow channel 31.

[0072] This setup allows for the gradual removal of oil and dust of varying sizes through multi-stage filtration, achieving a superior filtration effect and ensuring the cleanliness of the airflow ultimately discharged from the refrigerated dryer 100. Optionally, in some embodiments, the filter assembly 30 includes a first filter 32, a second filter 33, and a third filter 34 connected in sequence. The pore size of the filter element in the first filter 32 can be set to 1 micrometer, the pore size of the filter element in the second filter 33 can be set to 0.1 micrometer, and the pore size of the filter element in the third filter 34 can be set to 0.01 micrometer.

[0073] Please see Figure 3 and Figure 4 In some embodiments of this application, the filter assembly 30 further includes a drain pipe 35.

[0074] In this embodiment, the drain pipe 35 can remove impurities such as oil, dust, and moisture adsorbed in the filter assembly 30, thereby cleaning the filter assembly 30 and enabling it to be reused, thus extending its service life. Optionally, a drain valve can be installed on the drain pipe 35. When the drain valve is opened, the dirt in the drain pipe 35 can be discharged outwards. When the drain valve is closed, the dirt accumulates in the drain pipe 35. In this case, the filter assembly 30 can be drained periodically as needed, eliminating the need for it to be in a constant state of drainage, thus improving ease of use.

[0075] See also Figures 2 to 4In some embodiments of this application, the refrigerated dryer 100 further includes a mounting shell 40, which has a mounting cavity 41 in which the first cooling component 10, the second cooling component 20, and the filter component 30 are all disposed.

[0076] In this embodiment, the mounting shell 40 of the refrigerated dryer 100 serves as a supporting base, used to support the first cooling component 10, the second cooling component 20, and the filter component 30, etc., making the refrigerated dryer 100 modular in design, facilitating the overall disassembly, assembly, and movement of the refrigerated dryer 100, and improving ease of use. Optionally, at least one structure such as a handle or casters can be provided on the mounting shell 40 to facilitate the handling of the refrigerated dryer 100.

[0077] Optionally, an air inlet connector 43 and an air outlet connector 44 can be provided on the mounting housing 40. The air inlet connector 43 is connected to the airflow inlet of the first flow channel 11 in the first cooling assembly 10, and the air outlet connector 44 is connected to the airflow outlet of the filter assembly 30. Alternatively, when the first cooling assembly 10 has a refrigerant flow channel connected to the third flow channel 31 of the filter assembly 30, the air outlet connector 44 is connected to the airflow outlet of the refrigerant flow channel. With this configuration, an air compressor or other air supply equipment can be connected to the air inlet connector 43 of the refrigerated dryer 100, and the air-using equipment can be connected to the air outlet connector 44 of the refrigerated dryer 100, thereby achieving quick assembly and disassembly.

[0078] See also Figure 3 and Figure 4 In some embodiments of this application, the mounting shell 40 is provided with a first partition 42, which divides the mounting cavity 41 into a first chamber 411 and a second chamber 412. The first partition 42 is provided with a first clearance opening 421 connecting the first chamber 411 and the second chamber 412. The first cooling assembly 10 and the filter assembly 30 are disposed in the first chamber 411, and the second cooling assembly 20 is disposed in the second chamber 412. The connecting pipe of the first cooling assembly 10 and the filter assembly 30 to the second cooling assembly 20 passes through the first clearance opening 421.

[0079] This arrangement, by dividing the space within the mounting cavity 41 through the first partition 42, can reduce mutual interference during the installation of various components. In some embodiments of this application, the first cooling component 10 uses a smaller heat exchange module, while the second cooling component 20 uses a larger semiconductor refrigeration component or compressor refrigeration component, etc. In this case, the first cooling component 10 and the filter component 30 are placed in the first chamber 411, and the second cooling component 20 is placed in the second chamber 412. The component distribution is reasonable, the space utilization is high, and it is beneficial to reduce the size of the refrigerated dryer 100.

[0080] In some embodiments, the first partition 42 can also provide an installation base for at least some components or structures in the refrigerated dryer 100, so as to make the arrangement of components in the refrigerated dryer 100 more flexible and help to reduce the volume of the refrigerated dryer 100.

[0081] Please see Figure 5 The mounting housing 40 is provided with a second partition 46, which is disposed between the first cooling assembly 10 and the filter assembly 30.

[0082] This configuration, by isolating the installation spaces of the first cooling component 10 and the filter component 30 through the second partition 46, can reduce mutual interference during the installation of the various components. The second partition 46 is provided with a second clearance opening 461, through which the connecting pipe between the first cooling component 10 and the filter component 40 can pass.

[0083] Optionally, the mounting housing 40 is provided with a first partition 42 and a second partition 46. In this case, two first clearance openings 421 can be provided on the first partition 42 respectively. The connecting pipe between the first cooling component 10 and the second cooling component 20 passes through one of the first clearance openings 421, and the connecting pipe between the filter component 30 and the second cooling component 20 passes through the other first clearance opening 421. Alternatively, only one first clearance opening 421 can be provided on the first partition 42. For example, the first clearance opening 421 connects the mounting area of ​​the first cooling component 10 and the second chamber 412, so that the connecting pipe between the filter component 30 and the second cooling component 20 passes through the first clearance opening 421 and the second clearance opening 461 in sequence.

[0084] Please see Figure 2 In some embodiments of this application, the mounting shell 40 is provided with a vent 45 that connects the mounting cavity 41 to the external environment.

[0085] In this embodiment, the vent 45 can serve as a heat dissipation vent to improve the heat dissipation efficiency of the refrigerated dryer 100 and prevent the refrigerated dryer 100 from overheating and affecting the cooling effect on the airflow.

[0086] This application also proposes an air supply system for a laser processing system 1000. The air supply system includes an air compressor and a refrigerated dryer 100. The specific structure of the refrigerated dryer 100 is as described in the above embodiment, with the air outlet of the air compressor connected to the airflow inlet of the refrigerated dryer 100. The air compressor, or air compressor, can pressurize air and discharge it. The discharged compressed gas enters the refrigerated dryer 100 for filtration and secondary cooling to remove oil, dust, and moisture from the compressed gas and reduce its temperature. The air supply system can be applied to the laser processing system 1000 to provide auxiliary gas. For example, during laser cutting operations, the auxiliary gas provided by the air supply system can be used to blow away molten slag at the cutting location and to cool the cutting surface.

[0087] Since the gas supply system proposed in this application can adopt all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0088] This application also proposes a laser processing system 1000, which includes the gas supply system described in any of the foregoing embodiments. The specific structure of the gas supply system is as described in the above embodiments. The laser processing system 1000 further includes a laser module 200, which generates and emits laser light to perform at least one laser processing treatment on the workpiece, including but not limited to laser cutting, laser welding, laser marking, laser cleaning, laser engraving, and laser drilling. During laser processing, the airflow output from the gas supply system can be directed towards the processing area to remove waste generated during processing and to dissipate heat and protect the processing area.

[0089] Optionally, the gas supply system can be connected to the laser nozzle 2011 of the laser module 200, or the gas supply system can be connected to the laser path in the laser nozzle 2011, so that the light and gas are coaxially output to the processing position. Alternatively, an airflow path independent of the laser path can be provided in the laser nozzle 2011, and the gas supply system can be connected to the airflow path so that the airflow is blown to the processing position through the airflow path. In some embodiments, an air nozzle 300 independent of the laser nozzle 2011 can also be provided, and the gas supply system can be connected to the air nozzle 300 so that the airflow is blown to the processing position through the air nozzle 300.

[0090] Optional, please refer to Figure 6 The laser processing system 1000 proposed in this application can be configured as a handheld processing device. The laser module 200 includes a handheld laser head 201, for example, configured as a handheld welding torch, allowing for laser processing through handheld operation. Please refer to... Figure 7In some embodiments, the laser processing system 1000 can also be configured as an automated processing device, with the laser head 201 mounted on the moving component 500, and the moving component 500 driving the laser head 201 to translate and / or rise and fall, so as to achieve automated processing.

[0091] Since the laser processing system 1000 proposed in this application can adopt all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0092] Please refer to Figure 7 In one embodiment, the laser processing system 1000 further includes a frame 400 and a laser module 200. The frame 400 is provided with a processing area. The laser module 200 includes a laser generator 202 and a laser head 201 connected to each other. The laser head 201 is provided with a laser nozzle 2011 facing the processing area. The laser generator 202 is used to generate laser light and deliver the laser light to the laser head 201 so that the laser light is directed from the laser nozzle 2011 to the processing area. The gas supply system is connected to the laser nozzle 2011.

[0093] Specifically, the frame 400 serves as the supporting foundation for the laser processing system 1000, and can be used to install and connect other components of the laser processing system 1000. The frame 400 is provided with a processing area for placing workpieces. The laser head 201 of the laser module 200 is located above the processing area, and the laser nozzle 2011 is positioned facing the processing area. The laser generated by the laser generator 202 is directed towards the processing area through the laser head 201 to perform laser processing on the workpiece placed on the processing area. Optionally, both the laser generator 202 and the laser head 201 can be mounted on the frame 400. For example, the laser generator 202 and the laser head 201 can be configured as an integral structure, allowing the laser module 200 to be modularly mounted on the frame 400. In some embodiments, the laser generator 202 can be located outside the frame 400, while the laser head 201 is mounted inside the frame 400, with the laser head 201 and the laser generator 202 connected by an optical cable 203. Optionally, the laser head 201 can be configured as a handheld welding gun and detachably connected to the frame 400. In this case, the laser head 201 can be installed in the frame 400 and moved by the moving component 500 to achieve automated processing, or the laser head 201 can be detached from the frame 400 for handheld use.

[0094] A laser nozzle 2011 is provided near the processing area of ​​the laser head 201. A laser path is formed in the laser nozzle 2011 for the laser to pass through, and it can also be used to guide auxiliary gas to be blown towards the laser action area. The auxiliary gas can flow through the laser path to be blown towards the laser action area, that is, to achieve coaxiality of the light and gas. At this time, the gas supply system is connected to the laser path.

[0095] Optionally, the laser nozzle 2011 may include a nozzle body and an inner core. The inner core is retractably inserted into the nozzle body, and the laser path runs through the nozzle body and the inner core. Part of the inner core can extend out of the nozzle body under gravity. In this configuration, during laser processing, part of the inner core extends out of the nozzle body and contacts the workpiece, which can prevent some airflow from leaking through the gap between the laser nozzle 2011 and the workpiece, improve the utilization rate of the auxiliary gas, and thus use lower air pressure and airflow to remove waste generated during processing, as well as dissipate heat and protect the processing position. This also allows for the installation of a relatively low-pressure air compressor in the air supply system, and facilitates the miniaturization of the air supply system for use in environments with limited space, such as desktop laser processing systems 1000.

[0096] In some embodiments, an airflow path independent of the laser path can also be provided in the laser nozzle 2011, with the air supply system connected to the airflow path, and the airflow provided by the air supply system blown towards the laser action area through the airflow path.

[0097] Optionally, the main body of the laser processing system 1000 may also include a moving component 500 for driving the laser head 201 to translate and / or lift. For example, a translation component may be provided to drive the laser head 201 to translate to different positions for processing, and a lifting component may be provided to drive the laser head 201 to lift to adjust the height of the laser head 201. The height of the laser focus can be adjusted to meet different processing requirements and can also be applied to the processing of workpieces of different thicknesses.

[0098] The above are merely exemplary embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the technical concept of this utility model and the contents of the specification and drawings of this utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
