[0002] Argon arc welding, as a high-quality and high-precision electric arc welding process, is a core connection technology in high-end equipment manufacturing, precision machining and other fields. With the in-depth advancement of the Made in China strategy, strategic emerging industries represented by intelligent manufacturing equipment have put forward revolutionary requirements for the automation and intelligence level of welding technology.

[0003] Most existing automated argon arc welding equipment simply combines the welding actuator, workpiece positioning and motion mechanism, and auxiliary function system as independent units. This model results in a large equipment footprint, a lack of efficient coordination between subsystems, and limited overall operating efficiency. Secondly, although argon arc welding produces less spatter, a small amount of metal spatter, fumes, and oxide particles will still be generated when welding certain materials or using improper parameters. If these byproducts are scattered on the workbench, workpiece surface, or critical equipment components, they will not only pollute the working environment and affect the health of operators, but also accelerate equipment wear and interfere with the normal operation of precision components such as vision sensors.

[0011] Preferably, the circulating cooling mechanism includes a cooling water tank, a cooling bend, a water pump, and a radiator.

Compared with existing technologies, this automated argon arc welding device uses purified airflow discharged by a fan, which is guided to the radiator through auxiliary heat exchange tubes. The airflow accelerates the heat dissipation of the radiator, causing the cooling water temperature to drop more quickly. Then the airflow is discharged into the atmosphere. The forced air-cooled radiator enhances the heat dissipation capacity of the cooling system, ensuring that the coolant can remain at a suitable temperature. The airflow discharged from the dust removal system is used as a free air-cooling source for the cooling system, realizing the reuse of waste energy airflow within the system. This is energy-saving and environmentally friendly, eliminating the need to add a high-power fan for cooling, and reducing energy consumption and noise. Attached Figure Description

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Example 1 As attached Figures 1 to 7 An automated argon arc welding device is shown, including a worktable 1, a welding table 2 on one side of the worktable 1, a six-axis robotic arm 3 fixedly connected to the upper surface of the middle part of the worktable 1, a welding torch 4 fixedly connected to the end of the six-axis robotic arm 3, a rotating bearing plate 5 arranged on the upper surface of the welding table 2, a drive cavity 6 in the middle of the welding table 2, the drive cavity 6 being located at the bottom of the rotating bearing plate 5, a wire feeding mechanism 21 inside the worktable 1, and a circulating cooling mechanism 27 on one side of the wire feeding mechanism 21.

[0020] During operation, the workpiece to be welded is fixed on the rotating support plate 5 of the welding table 2. The six-axis robotic arm 3 drives the welding torch 4 to move to the starting welding position. After welding begins, the six-axis robotic arm 3 controls the spatial trajectory of the welding torch 4, while the rotating support plate 5 can rotate under the drive of the mechanism in the drive cavity 6, causing the workpiece to rotate. The two work together to realize the automated welding of complex welds such as circumferential welds and spatial curves. Through the collaborative mode of the six-axis robotic arm 3 and the rotating support plate 5, the welding operation is automated. The layout of the rotating support plate 5 allows for alternating preparation and welding at multiple stations, improving equipment utilization and work efficiency. The wire feeding mechanism 21 can automatically push the welding wire, thereby realizing automatic continuous welding. The circulating cooling mechanism 27 can cool the welding torch 4 to avoid overheating and affecting the welding.

[0021] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 7 As shown below, see details: In a preferred embodiment, a drive rod 7 is connected to the inner wall of the middle part of the drive cavity 6 via a bearing. The top end of the drive rod 7 is fixedly connected to the rotating support plate 5. Both the rotating support plate 5 and the surface of the welding table 2 are provided with positioning holes 8, and the positioning holes 8 on the surface of the rotating support plate 5 are connected to the drive cavity 6. A servo motor 9 is fixedly connected to the inner wall of the top of the welding table 2. The output end of the servo motor 9 is connected to the drive rod 7. The servo motor 9 receives commands from the control system and accurately outputs the rotation speed and angle. Its output torque is directly transmitted to the rotating support plate 5 through the drive rod 7, driving it to rotate smoothly. The positioning holes 8 can be used to install fixture positioning pins to achieve rapid and accurate positioning and clamping of the workpiece. Welding slag, spatter, etc. can fall into the drive cavity 6 below through the positioning holes 8 on the support plate. This provides a specific implementation scheme for rotation drive. The servo motor 9 ensures that the rotation speed is accurately adjustable to meet the speed requirements of different welding processes. The design of the positioning holes 8 not only facilitates workpiece clamping but also forms a downward contaminant discharge channel, initially solving the problem of cleaning up chips in the welding area and keeping the table surface clean.

[0022] In a preferred embodiment, an auxiliary support rod 10 is fixedly connected to the inner wall of the edge of the drive cavity 6. Multiple sets of auxiliary support rods 10 are arranged circumferentially. An auxiliary ball bearing 11 is embedded in the top of each auxiliary support rod 10, and the ball bearing 11 abuts against the rotating bearing disk 5. A first gear 12 is fixedly connected to the outer wall of the middle section of the drive rod 7. Blade rods 13 are provided on both sides of the drive rod 7. The bottom end of each blade rod 13 is connected to the inner wall of the drive cavity 6 via a bearing. A second gear 14 is fixedly connected to the outer wall of the middle section of the blade rod 13. The second gear 14 meshes with the first gear 12. The diameter of the first gear 12 is larger than that of the second gear 14. An auxiliary blade 15 is fixedly connected to the top of the blade rod 13. When the servo motor 9 drives the drive rod 7 and the first gear 12 to rotate, the gear meshing drives… The second gear 14 and the blade rod 13 on both sides rotate in opposite directions at a higher speed. The auxiliary blade 15 at the top of the blade rod 13 rotates at high speed accordingly. The auxiliary ball bearing 11 at the top of the auxiliary support rod 10 supports the rotating bearing disk 5, reducing its rotational friction. Through the support of the auxiliary ball bearing 11 distributed at multiple points, the radial load on the drive rod 7 is greatly reduced, making the rotating bearing disk 5 rotate more smoothly and steadily, extending the life of the drive mechanism. The main drive power is creatively utilized to drive the auxiliary blade 15 to rotate at high speed through the first gear 12 and the second gear 14. This generates a directional airflow from top to bottom in the drive cavity 6. This airflow can quickly blow the welding slag and dust particles falling through the positioning hole 8 to the bottom collection tank 16, realizing the automatic and real-time primary collection of welding waste without the need for additional power, which is energy-saving and efficient.

[0023] In a preferred embodiment, a sludge collection tank 16 is provided at the bottom of the drive chamber 6, a filter screen 17 is provided in the middle of the sludge collection tank 16, and an adsorption layer 19 is provided at the bottom of the filter screen 17. An air guide pipe 18 is connected to one side of the sludge collection tank 16, and a fan 20 is provided on one side of the bottom of the welding table 2 via the air guide pipe 18. Pollutants driven down by the airflow from the auxiliary fan 15 fall into the sludge collection tank 16. First, larger particles are intercepted by the filter screen 17. The airflow containing fine dust continues downwards, passing through the adsorption layer 19 (such as activated carbon) to adsorb odors and even finer particles. Finally... Under the suction of the fan 20, the purified air is discharged through the air duct 18, maintaining the negative pressure environment in the drive chamber 6, enhancing the dust removal effect, and forming a complete graded purification system. The filter screen 17 performs coarse filtration, protecting the subsequent fan 20 and facilitating the cleaning of large particles. The adsorption layer 19 performs fine filtration and deodorization, effectively purifying welding fumes. The fan 20 provides stable negative pressure, which works in conjunction with the airflow generated by the auxiliary fan blades 15 to form a highly efficient dual dust removal mechanism of active blowing and negative pressure suction, improving the working environment and protecting the internal structure of the equipment from pollution.

[0024] In a preferred embodiment, the wire feeding mechanism 21 includes a wire feeding frame 22, a wire feeding reel 23, a wire feeding motor 24, a wire guide tube 25, and a straightening frame 26. The wire feeding frame 22 is fixedly connected to one side of the inner wall of the workbench 1. The wire feeding reel 23 is connected to the middle of the wire feeding frame 22 via a bearing. The welding wire roll is installed on the wire feeding reel 23. During welding, the wire feeding motor 24 drives the wire feeding reel 23 to rotate, smoothly pulling the welding wire out of the reel. After the pulled-out welding wire passes through the straightening frame 26 to eliminate bending stress, it enters the wire guide tube 25 and is guided to the end of the welding torch 4. The wire feeding mechanism 21 is built into the workbench 1, which has a compact structure, saves external space, avoids the messy pipelines and collision risks caused by an external wire feeder, and the built-in design also facilitates overall protection and management.

[0025] In a preferred embodiment, a wire feeding motor 24 is fixedly connected to one side of the wire feeding frame 22. The output end of the wire feeding motor 24 is fixedly connected to the central shaft of the wire feeding reel 23 via a coupling. A wire guide tube 25 is provided on one side of the wire feeding reel 23. The end of the wire guide tube 25 away from the wire feeding reel 23 extends to the vicinity of the welding torch 4. A straightening frame 26 is fixedly connected to one side of the upper surface of the worktable 1. The top end of the straightening frame 26 is connected to the wire guide tube 25. The wire feeding motor 24 serves as a power source, directly driving the central shaft of the wire feeding reel 23 to feed the wire. The fed welding wire first passes through the straightening frame 26 and is straightened by the alignment of multiple sets of straightening wheels to ensure that the welding wire entering the wire guide tube 25 is straight and is finally accurately delivered to the molten pool. The straightening frame 26 ensures the straightness of the flexible welding wire after long-distance transport, avoids the welding wire from getting stuck in the wire guide tube 25 or being unstable in the feeding direction, thereby ensuring the wire feeding accuracy and the stability of the welding process.

[0026] In a preferred embodiment, the circulating cooling mechanism 27 includes a cooling water tank 28, a cooling bend 281, a water pump 29, and a radiator 30. The cooling bend 281 is provided on one side of the cooling water tank 28, and both ends of the cooling bend 281 are connected to the cooling water tank 28. The cooling bend 281 extends along the wire guide tube 25 to one side of the welding torch 4. Cooling water is stored in the cooling water tank 28. After the water pump 29 is started, it drives the cooling water circulation. The cooling water flows out of the tank, passes through the cooling bend 281, and reaches the water cooling channel inside the welding torch 4 to absorb the large amount of heat generated when the welding torch 4 is working. The heated water then returns to the system through the other end of the cooling bend 281. Water cooling can efficiently remove the high heat generated during high-current welding, prevent the welding torch 4 from overheating and being damaged, and allow the device to perform long-term, high-current continuous welding operations, thereby improving the equipment's workload capacity and reliability.

[0027] In a preferred embodiment, a water pump 29 is installed at one end of the cooling bend 281, and a radiator 30 is connected to one side of the middle of the cooling bend 281. An auxiliary heat exchange pipe 31 is connected to the side of the fan 20 away from the air guide pipe 18. The exhaust end of the auxiliary heat exchange pipe 31 is located on one side of the radiator 30. The warm water returning from the welding torch 4 passes through the radiator 30 for heat dissipation before flowing back to the cooling water tank 28. At the same time, the purified airflow discharged by the fan 20 is guided to the radiator 30 through the auxiliary heat exchange pipe 31 and blown over it. The airflow accelerates the heat dissipation of the radiator 30, making the cooling water temperature drop faster. Then the airflow is discharged into the atmosphere. The forced air cooling of the radiator 30 enhances the heat dissipation capacity of the cooling system, ensuring that the coolant can remain at a suitable temperature. The airflow discharged from the dust removal system is used as a free air cooling source for the cooling system, realizing the reuse of waste energy airflow in the system, saving energy and protecting the environment. There is no need to add a high-power fan for cooling, reducing energy consumption and noise.

[0028] In a preferred embodiment, a vision sensing module 32 is integrated on one side of the welding torch 4. The vision sensing module 32 includes a laser stripe emitter 33 and a high-speed camera 34. The laser stripe emitter 33 is fixedly connected to the outer wall of one side of the worktable 1, and the high-speed camera 34 is set on one side of the laser stripe emitter 33. A receiver controller 35 is fixedly connected to the inner wall of the worktable 1. Before or during welding, the laser stripe emitter 33 projects a line of laser light into the weld area. The high-speed camera 34 simultaneously captures the deformation image of the laser stripe on the workpiece surface. The image processing unit of the receiver controller 35 analyzes the image and calculates the precise position of the weld, the bevel size, and even the three-dimensional morphology of the molten pool in real time. It can compensate for weld position deviations caused by workpiece assembly errors, thermal deformation, etc., and guide the robotic arm to automatically adjust its trajectory to ensure welding accuracy.

[0029] The working process of this application is as follows: First, the workpiece to be welded is fixed on the rotating support plate 5 of the welding table 2. The six-axis robotic arm 3 drives the welding torch 4 to move to the starting welding position. After welding begins, the six-axis robotic arm 3 controls the spatial trajectory of the welding torch 4, while the rotating support plate 5 can rotate under the drive of the mechanism in the drive cavity 6, causing the workpiece to rotate. The two work together to achieve automated welding of complex welds such as circumferential welds and spatial curves. Through the collaborative mode of the fixed robotic arm and the rotating support plate 5, the welding operation is automated. The layout of the rotating support plate 5 allows for alternating preparation and welding at multiple workstations, improving equipment utilization and work efficiency. The wire feeding mechanism 21 can automatically push the welding wire, thereby achieving automatic continuous welding. The fixture positioning pin is installed through the positioning hole 8 to achieve rapid and accurate positioning and clamping of the workpiece. Welding slag, spatter, etc. can fall into the drive cavity 6 below through the positioning hole 8 on the support plate. The servo motor 9 ensures that the rotation speed is precisely adjustable to meet the speed requirements of different welding processes. As required, when the servo motor 9 drives the drive rod 7 and the first gear 12 to rotate, the gear meshing drives the second gear 14 and the blade rod 13 on both sides to rotate in the opposite direction at a higher speed. The first gear 12 and the second gear 14 increase the speed, driving the auxiliary blade 15 to rotate at high speed, generating a directional airflow from top to bottom in the drive cavity 6. This airflow can quickly blow the welding slag and dust particles falling through the positioning hole 8 to the bottom collection tank 16, realizing automatic and real-time primary collection of welding waste. No additional power is required, which is energy-saving and efficient. Before or during welding, the laser stripe emitter 33 projects a line laser to the weld area. The high-speed camera 34 simultaneously captures the deformation image of the laser stripe on the workpiece surface. The image processing unit of the receiver controller 35 analyzes the image and calculates the precise position of the weld, the bevel size, and even the three-dimensional shape of the molten pool in real time. It can compensate for the weld position deviation caused by workpiece assembly error, thermal deformation, etc., and guide the robotic arm to automatically adjust the trajectory to ensure welding accuracy. Cooling water is stored in cooling water tank 28. After water pump 29 starts, it drives the cooling water circulation. Cooling water flows out of the tank, passes through cooling bend 281, and reaches the water-cooling channel inside welding torch 4. It absorbs the large amount of heat generated when welding torch 4 is working. The warm water after absorbing heat returns to the system through the other end of cooling bend 281. Water cooling can efficiently remove the high heat generated during high-current welding, preventing the welding torch 4 from overheating and being damaged. This allows the device to perform long-term, high-current continuous welding operations, improving the equipment's workload capacity and reliability. The warm water returning from welding torch 4 flows back to cooling water tank 28. Before the 8th airflow, the airflow passes through the radiator 30 for heat dissipation. At the same time, the purified airflow discharged by the fan 20 is guided to the radiator 30 through the auxiliary heat exchange tube 31. The airflow accelerates the heat dissipation of the radiator 30, making the cooling water temperature drop faster. Then the airflow is discharged into the atmosphere. The forced air-cooled radiator 30 enhances the heat dissipation capacity of the cooling system, ensuring that the coolant can remain at a suitable temperature. The airflow discharged by the dust removal system is used as a free air cooling source for the cooling system, realizing the reuse of waste energy airflow in the system. This is energy-saving and environmentally friendly, and there is no need to add a high-power fan for cooling, reducing energy consumption and noise.
