[0036] Refer to Figure 1 and Figure 2As shown in the figure, the present application proposes an integrated portable laser welding device 300. The integrated portable laser welding device 300 includes a housing 31, a heat dissipation module 32, a laser module 33, a wire reel and wire guiding module 35, a laser welding head 36, and a nitrogen generator 100. Among them, the heat dissipation module 32, the laser module 33, the wire reel and wire guiding module 35, and the nitrogen generator 100 are all arranged inside the housing 31. The heat dissipation module 32 is connected to the laser module 33 and is used to dissipate heat from the laser module 33. Both the laser module 33 and the nitrogen generator 100 are connected to the laser welding head 36. The wire reel and wire guiding module 35 are used to supply wire to the laser welding head 36. Among them, the nitrogen generator 100 includes an air compressor 20, a dryer 30, and a nitrogen production component 10, and the nitrogen generator 100 is detachably arranged at the bottom of the housing 31.

[0037] In the technical solution of the present application, the structural arrangement of the integrated portable laser welding device 300 is proposed.

[0038] Among them:

[0039] The housing 31 plays a role in protecting and supporting the internal components.

[0040] The laser module 33 is used to generate a welding laser beam.

[0041] The heat dissipation module 32 is connected to the laser module 33. In this way, the heat generated by the laser module 33 can be quickly dissipated through the heat dissipation module 32, ensuring the stable operation of the laser module 33 and avoiding performance degradation or damage caused by overheating. The heat dissipation module 32 can be a combination of a heat pipe module 321, a heat sink module 322, and a wind cooling module 323. Thus, through the high-efficiency conduction performance of the heat pipe, the heat generated by the laser module 33 can be quickly conducted to the heat sink, and the heat exchange efficiency can be improved by the characteristic of the large heat dissipation area of the heat sink, and the heat is dissipated into the air. Further, the heat dissipation fan is used to accelerate the air flow speed around the heat sink to improve the heat dissipation effect.

[0042] The wire reel and wire guiding module 35, where the wire reel 351 is used to store wire, and the wire guiding module 352 is responsible for accurately delivering the wire from the wire reel 351 to the laser welding head 36. Thus, the stable supply of wire is ensured, which is conducive to achieving high-quality welding.

[0043] The laser welding head 36 is connected to the laser module 33 through an armored cable 37 and is responsible for guiding the laser beam generated by the laser module 33 to the welding area and completing the welding process together with the wire.

[0044] The nitrogen generator 100 is connected to the laser welding head 36. During the laser welding process, nitrogen, as a shielding gas, can effectively prevent the welding area from being oxidized or contaminated, improving the welding quality and the appearance of the weld.

[0045] Further, the nitrogen generator 100 proposed in the present application is an integrated body of nitrogen production components such as an air compressor 20, a dryer 30, and a nitrogen production component 10, and is detachably arranged at the bottom of the housing 31. In this way, since the nitrogen production components are integrated to form the nitrogen generator 100, redundant space between the components can be avoided, making the overall structure of the nitrogen generator 100 more compact and achieving a reduction in volume. Moreover, when assembling the laser welding equipment, only the integrated nitrogen generator 100 needs to be installed and debugged as a whole, reducing the complexity of installation. The integrated nitrogen generator 100 is detachably connected to the housing 31, and thus the nitrogen generator 100 can be detached from the housing 31 as a whole for modular maintenance.

[0046] In some embodiments, the housing 31 is designed to be openable to expose the nitrogen generator 100, and a guiding and locking structure (not shown in the drawings) is provided between the nitrogen generator 100 and the bottom of the housing 31. The nitrogen generator 100 is slidably arranged at the bottom of the housing 31 through the guiding and locking structure.

[0047] In this embodiment, the housing 31 being openable includes that the housing 31 can be disassembled or the shell surface of the housing 31 is hinged, at least including that the side surface of the housing 31 can be opened to expose the nitrogen generator 100 arranged therein. Furthermore, when the nitrogen generator 100 needs to be installed, the nitrogen generator 100 can be connected to the guiding and locking structure, and the user can push the nitrogen generator 100 into the preset installation position in the housing 31 for fixation. Or when the nitrogen generator 100 needs to be maintained, the user can pull the nitrogen generator 100 to make the nitrogen generator 100 lean towards the outside or detach from the housing 31, thus facilitating the installation and disassembly of the nitrogen generator 100 and being conducive to modular maintenance operations.

[0048] In some embodiments, the guiding and locking structure includes a guide rail and a locking member; the nitrogen generator 100 is slidably arranged on the guide rail and can reciprocate along the guide rail; the locking member is arranged corresponding to the nitrogen generator 100 on the guide rail and is used to lock the relative position between the nitrogen generator 100 and the guide rail after the nitrogen generator 100 is installed in place.

[0049] In this embodiment, the guide rail is fixed to the bottom of the housing 31, providing a clear and stable sliding path for the nitrogen generator 100. The nitrogen production components in each nitrogen generator 100 can be integrally installed on a mounting plate, and a chute or roller matching the guide rail is arranged at the bottom or side surface of the mounting plate, so that the nitrogen generator 100 can closely fit the guide rail and slide along it. The purpose of the locking member is to stabilize the state of the nitrogen generator 100 installed in the housing 31. When the nitrogen generator 100 slides along the guide rail to the predetermined installation position, the locking member will automatically or manually intervene to firmly lock the nitrogen generator 100 on the guide rail to prevent it from moving or falling off due to accident.

[0050] Further, the locking member includes, but is not limited to, locking methods such as a mechanical lock, magnetic locking, and a bolt lock.

[0051] In some embodiments, the heat dissipation module 32 and the laser module 33 enclose an installation area 34, and the installation area 34 is docked to the guide rail. Furthermore, the nitrogen generator 100 can be arranged in the installation area 34 in a pull-out manner, further saving the installation space in the housing 31 and facilitating the miniaturization of the laser welding equipment.

[0052] Refer to Figure 3 and Figure 4 As shown, in some embodiments, the nitrogen generation component 10 includes a box body 101 and an air tank 11, an adsorption tower, and a nitrogen tank 12 arranged in the box body 101; the air tank 11, the adsorption tower, and the nitrogen tank 12 are all connected with tracheal interfaces 15 arranged on the box body 101, and the adsorption tower includes an adsorption tower A 13 and an adsorption tower B 14; wherein, the air compressor 20, the air tank 11, the dryer 30, the adsorption tower, and the nitrogen tank 12 are connected in sequence.

[0053] Among them, the air compressor 20 serves as the power source of the nitrogen generator 100 and is responsible for compressing air to a certain pressure for supply; the dryer 30 is used to remove moisture and humidity in the compressed air to prevent affecting the nitrogen purity in the subsequent treatment process; the nitrogen generation component 10 is the core part of the nitrogen generator 100 and is used to separate nitrogen from the compressed and dried air.

[0054] The structural composition of the nitrogen generation component 10 is further proposed. Specifically, the air tank 11, the adsorption tower, and the nitrogen tank 12 can be fixed in the box body 101 through an installation frame, a screw locking structure, etc. In this way, during the assembly process of the nitrogen generator 100, only the nitrogen generation component 10 needs to be installed and debugged as a whole, so as to reduce the complexity of the installation of the nitrogen generator 100 and reduce the installation time and labor costs.

[0055] Among them, the air tank 11 is used to store air to ensure that the nitrogen generator 100 can still supply gas continuously in a short time during operation; the adsorption tower is used to remove impurities such as oxygen in the air to obtain high-purity nitrogen; and the nitrogen tank 12 is used to collect and store the generated finished nitrogen for subsequent use.

[0056] Furthermore, the adsorption tower is provided with an adsorption tower A 13 and an adsorption tower B 14. Usually, the adsorption tower A 13 and the adsorption tower B 14 operate in an alternating manner, that is, when one adsorption tower is performing an adsorption operation, the other adsorption tower is performing a desorption or regeneration operation to ensure the continuity and efficiency of the nitrogen generation process.

[0057] In addition, each unit in the nitrogen generation component 10 is correspondingly provided with a tracheal interface 15. These tracheal interfaces 15 are connection ports for connecting external components and internal units, and can be used to implement operations such as air input, nitrogen output, and gas circulation and regeneration in the adsorption tower. By reasonably arranging and connecting these tracheal interfaces 15, the smooth operation and efficient work of the nitrogen generation process can be ensured.

[0058] Refer to Figure 3 and Figure 4 As shown, in some embodiments, at least part of the air tank 11, adsorption tower A 13, adsorption tower B 14, and nitrogen tank 12 are arranged in a stacked manner inside the box body 101.

[0059] In this embodiment, by stacking the units vertically, the space inside the box body 101 can be effectively utilized and the floor area can be reduced, further reducing the volume of the overall nitrogen generator 100. Among them, the number and type of the selected stacked settings can be set according to the actual usage needs of users. Exemplarily, the overall shape of the box body 101 is a block formed by extending with an "L"-shaped stepped cross-section, aiming to balance the occupied space of the integrated components in the vertical and horizontal directions, so as to reduce the occupied volume when the layout of each nitrogen generation area can be completed. Among them, the air tank 11, nitrogen tank 12, and adsorption tower B 14 are stacked in sequence from top to bottom on a part (the part with a higher height) of the "L"-shaped nitrogen generation component 10, and the adsorption tower A 13 is arranged on the other relatively vertical part (the other part with a lower height) of the "L"-shaped nitrogen generation component 10.

[0060] In some embodiments, a receiving space is formed between the bottom of the nitrogen generator and the bottom of the housing. A mobile power source is detachably arranged in the receiving space, and the mobile power source is used to supply power to the integrated portable laser welding device. The mobile power source is provided with a fan for power source heat dissipation.

[0061] In this embodiment, by arranging a detachable mobile power source in the receiving space between the bottom of the nitrogen generator and the bottom of the housing, it aims to supply power to the integrated portable laser welding device. At the same time, the detachable installation can improve the maintainability of the power source and the mobility of the welding device.

[0062] Refer to Figure 2 As shown, in some embodiments, a heat dissipation component 40 for reducing the temperature of the output air is arranged at the air outlet of the air compressor 20.

[0063] In this embodiment, by arranging the heat dissipation component 40 at the outlet of the air compressor 20, it aims to reduce the temperature of the air output by the air compressor 20, thereby reducing the burden on subsequent processing components (such as the dryer 30 and adsorption tower), and improving the efficiency and purity of nitrogen production.

[0064] Among them, the heat dissipation component 40 includes a water radiator structure, a fin radiator structure, a TEC type radiator structure, an accordion tube, etc., all of which can achieve good heat dissipation effects. Further, a cooling fan is provided corresponding to the heat dissipation component 40. The cooling fan can generate forced convection, accelerate the flow of hot air, and help the heat on the heat dissipation component 40 to be dissipated into the surrounding environment faster.

[0065] Refer to Figure 2 As shown, in some embodiments, an air filter 50 is connected to the air inlet of the air compressor 20, and the air filter 50 is connected to the air compressor 20 through an adapter device.

[0066] In this embodiment, the air filter 50 aims to remove impurities such as dust and particulate matter in the air entering the air compressor 20, effectively protect the air compressor 20, extend its service life, and improve the performance of the entire nitrogen production system. It can be understood that if impurities directly enter the air compressor 20, it will not only cause wear and damage to the internal components of the air compressor 20, but also affect the efficiency and nitrogen purity of the subsequent nitrogen production process.

[0067] The air filter 50 is connected to the air inlet of the air compressor 20 through an adapter device. The adapter device can be an adapter and an adapter pipeline, etc., so that the installation position can be adjusted according to the actual installation environment and requirements, which is convenient for replacing the filter mesh.

[0068] Furthermore, the air compressor 20 is connected with a pressure relief valve 21, which is used to reduce the air pressure in the air compressor 20 to ensure the normal start of the air compressor 20 next time.

[0069] Refer to Figure 2 As shown, in some embodiments, the nitrogen generator 100 further includes an oil-water separator 60, and both ends of the oil-water separator 60 are connected to the air tank 11 and the dryer 30.

[0070] In this embodiment, the oil-water separator 60 aims to remove the oil and water contained in the air. Before the compressed air enters the dryer 30, through the treatment of the oil-water separator 60, the oil mist and water in the air can be effectively removed, preventing these impurities from contaminating or damaging the dryer 30.

[0071] Refer to Figure 2 As shown, in some embodiments, the nitrogen generator 100 further includes a solenoid valve 70. The solenoid valve 70 includes: a first solenoid valve 71, which is arranged between the dryer 30 and the adsorption tower, and is used to control the on-off of the pipeline from the dryer 30 to the adsorption tower A13 and the on-off of the pipeline from the dryer 30 to the adsorption tower B14; a second solenoid valve 72, which is arranged between the adsorption tower and the nitrogen tank 12, and is used to control the on-off of the pipeline from the adsorption tower A13 to the nitrogen tank 12 and the on-off of the pipeline from the adsorption tower B14 to the nitrogen tank 12.

[0072] In this embodiment, the first solenoid valve 71 precisely controls the gas flow direction by controlling the opening and closing of the pipeline between the dryer 30 and the two adsorption towers, ensuring the continuity and stability of the nitrogen production process; the second solenoid valve 72 enables the nitrogen generator 100 to control the collection and storage process of nitrogen. By precisely controlling the opening and closing of the pipeline between the adsorption tower and the nitrogen tank 12, it ensures the efficient collection and purity of nitrogen.

[0073] Therefore, the introduction of the solenoid valve 70 makes the operation of the nitrogen generator 100 more automated and intelligent, reduces the need for manual intervention, and enables it to precisely control the gas flow direction and opening and closing, ensuring the stability and reliability of the nitrogen production process.

[0074] Refer to Figure 2 As shown, in some embodiments, the nitrogen generator 100 further includes an outlet control component 80. The outlet control component 80 is arranged on the outlet pipeline connected to the nitrogen tank 12; the outlet control component 80 includes a proportional control valve 81, a sensing control component 82, and an outlet 83 arranged in sequence.

[0075] Among them, the proportional control valve 81 is responsible for adjusting the outlet flow rate of nitrogen according to preset parameters or external signals. By precisely controlling the opening of the valve, continuous and stepless adjustment of the nitrogen flow rate can be achieved, thus meeting the requirements of different welding processes for nitrogen flow rate.

[0076] The sensing control component 82 includes a pressure sensor and an on-off control valve. The pressure sensor is used to detect whether the outlet flow rate adjusted by the proportional control valve 81 is reached in the outlet pipeline. Through a high-precision measurement and feedback mechanism, it ensures the accuracy and stability of nitrogen output. The on-off control valve is used to control the opening and closing of the outlet pipeline and closely cooperates with the pressure sensor. When the pressure sensor detects that the nitrogen flow rate reaches or exceeds the preset value, the on-off control valve will quickly respond and close the outlet pipeline to prevent excessive output or waste of nitrogen. At the same time, when it is necessary to stop the nitrogen supply, the on-off control valve can also quickly cut off the gas source, ensuring the safety and controllability of the welding process.

[0077] The outlet 83 is connected to the outlet pipeline and is used to output nitrogen. Among them, the outlet 83 is usually connected to the laser welding head 36. Thus, during the laser welding process, nitrogen acts as a shielding gas, effectively preventing the welding area from being oxidized or contaminated, and improving the welding quality and the appearance of the weld.

[0078] The above are only partial or preferred embodiments of the present application. Whether in terms of text or drawings, the scope of protection of the present application cannot be limited thereby. All equivalent structural transformations made under the overall concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, are included in the scope of protection of the present application.
