[0021] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0022] Reference Figure 1 to Figure 12, which is an embodiment of the present invention, proposes a consumable electrode welding device for welding a consumable electrode 15 and a dummy electrode 16 together, including a welding robot 1, the welding robot 1 is used to weld the connection 14 of the consumable electrode 15 and the dummy electrode 16; there are a plurality of roller frames 2, the plurality of roller frames 2 are arranged at intervals and slidably set on the front side of the welding robot 1; there are a plurality of bearing seats 3, each of which is slidably set on a bearing seat 3; there are a plurality of rotating wheel frames 4, each of which is provided with at least one rotating wheel frame 4, the consumable electrode The consumable electrode 15 and the dummy electrode 16 are placed on the rotating wheel frame 4 respectively, and the rotating wheel frame 4 is used to support the consumable electrode 15 and the dummy electrode 16. The consumable electrode 15 and the dummy electrode 16 are arranged concentrically, and the rotating wheel frame 4 is also used to drive the consumable electrode 15 and the dummy electrode 16 to rotate synchronously; the arc frame 12 is located on the ground at the bottom of the connection 14, and the arc frame 12 has a slideway 1201; the sliding seat 1202 is arranged on the slideway 1201; the hammer 13 is arranged on the sliding seat 1202, the hammer 13 is located at the connection 14, and the hammer 13 is used to hammer the oxide scale of the connection 14. In the above scheme, the welding robot 1 has high-precision motion control capability and can accurately locate the connection 14 between the consumable electrode 15 and the dummy electrode 16 for welding operation. Four roller frames 2 are configured, and the roller frames 2 are slidably connected to the track 9. The rotating wheel frame 4 on the bearing seat 3 uses a rubber-wrapped metal wheel, which can not only ensure good support for the electrode, but also effectively drive the electrode to rotate synchronously, and adapt to consumable electrodes 15 and dummy electrodes of different diameters. For example, when welding the consumable electrode 15 and the dummy electrode 16, by adjusting the bearing seat 3 and the rotating wheel frame 4, the concentric arrangement of the two can be quickly achieved.

[0023] Working process: First, the consumable electrode 15 and the dummy electrode 16 are hoisted and placed on the corresponding rotary frame 4, and the concentricity is preliminarily adjusted using the adjustment device of the rotary frame 4. The roller frame 2 operates according to the preset program, slides in front of the welding robot 1, and adjusts to the appropriate welding position spacing to ensure that the welding gun of the welding robot 1 can accurately cover the welding part. Then the welding robot 1 is started, and the robot arm 101 drives the welding gun to move to the starting welding point, and starts welding the connection 14 between the consumable electrode 15 and the dummy electrode 16. During the welding process, the rotary frame 4 rotates the consumable electrode 15 and the dummy electrode 16 synchronously at the set speed to ensure that the welding surface is evenly heated and stable welding is achieved.

[0024] Secondly, it should be noted that before welding, according to the welding position of the electrode, the arc frame 12 is installed above the connection 14 so that the hammer 13 is aimed at the welding part. When started, the hammer 13 hammers the connection 14 at a preset frequency, such as 30 times per minute with an impact force of 50N. During the hammering process, the sliding seat 1202 can be fine-tuned on the slideway 1201 according to the changes in the welding part to ensure that the hammer 13 hammers in the correct position. After the hammering is completed, the arc frame 12 is removed without affecting the subsequent welding operation. The arc frame 12 and the sliding seat 1202 can adapt to the shape of the electrode welding part, which is convenient for the hammer 13 to act accurately on the oxide scale. The position accuracy of the hammer 13 during the working process avoids damage to the electrode due to hammering deviation, while ensuring the oxide scale removal effect, which is conducive to improving the quality of the welded joint.

[0025] The automated welding robot 1 replaces manual welding, greatly improving welding accuracy, avoiding irregular welds caused by factors such as hand shaking in manual welding, and ensuring stable and reliable welding quality. It can also prevent workers from working in harsh welding environments. The combination of the roller frame 2 and the rotating wheel frame 4 realizes the rapid concentric arrangement and synchronous rotation of the consumable electrode 15 and the dummy electrode 16, which greatly shortens the preparation time and improves the overall welding efficiency compared to manual adjustment and rolling electrodes.

[0026] Furthermore, it also includes a gun cleaning station 5, which is arranged on one side of the welding robot 1. The gun cleaning station 5 has a gun cleaning unit 501, a wire cutting unit 502 and a silicone oil spraying unit 503. The gun cleaning unit 501 is used to clean the welding slag on the nozzle of the welding robot 1, the wire cutting unit 502 is used to correct the welding end of the welding wire, and the silicone oil spraying unit 503 is used to inject silicone oil into the inner surface of the nozzle of the welding robot 1.

[0027] In the above scheme, the gun cleaning unit 501 is equipped with a powerful air spray gun and a rotary reamer. The air spray gun pressure can reach 0.6MPa, which can effectively blow off the welding slag. The rotary reamer speed is as high as 1500rpm, which can quickly clean the welding slag in the nozzle. The wire cutting unit 502 adopts an electric wire cutting knife, which can trim the welding end of the welding wire to be flat and smooth, ensuring that the arc starting effect of the welding end of the welding wire is good. The silicone oil spraying unit 503 is equipped with a micro plunger pump, which can control the injection amount of silicone oil. The double nozzle cross-injection angle is 60°, so that the silicone oil evenly covers the inner surface of the nozzle. For example, when welding a high-strength alloy steel consumable electrode 15, the gun cleaning station 5 automatically starts every 5 weldings to maintain the welding gun of the welding robot 1.

[0028] After the welding robot 1 completes a certain number of welding tasks, it automatically moves to the gun cleaning station 5. The gun cleaning unit 501 is first started, and the air spray gun blows to clean the welding slag outside the nozzle. Then the rotary reamer extends and rotates deep into the nozzle to clean the residual welding slag. The wire cutting unit 502 then works, and the electric wire cutter moves to cut off the excess part of the welding end of the welding wire and correct it to the appropriate length. Finally, the silicone oil spraying unit 503 is started, and the micro plunger pump sprays silicone oil to the inner surface of the nozzle through the double nozzles to form a layer of anti-stick coating. By timely cleaning the welding slag of the welding gun nozzle, the accumulation of welding slag is prevented from affecting the welding quality, such as avoiding defects such as weld porosity and slag inclusion caused by welding slag, and ensuring welding stability. The precise wire cutting operation optimizes the arc starting effect, improves the stability of the welding start stage, and reduces the defects at the welding start point. Spraying silicone oil effectively reduces the adhesion of welding slag to the nozzle, reduces the frequency of welding gun cleaning, extends the service life of the welding gun, and reduces equipment maintenance costs and downtime.

[0029] Furthermore, the welding robot 1 includes a robotic arm 101, which has several degrees of freedom; a water-cooled welding gun 102 is detachably arranged on the robotic arm 101, and a nozzle is arranged on the water-cooled welding gun 102; a weld seam tracking sensor 103 is arranged on the robotic arm 101, and the weld seam tracking sensor 103 is located on a side close to the water-cooled welding gun 102, and the weld seam tracking sensor 103 is used to monitor the welding condition.

[0030] In the above scheme, the robot arm 101 has 6 degrees of freedom and can flexibly and accurately drive the water-cooled welding gun 102 to the welding position. The water cooling system of the water-cooled welding gun 102 adopts a closed-loop cooling circuit, and the cooling water flow rate can reach 3L / min to ensure that the welding gun does not overheat during long-term welding. The nozzle is made of ceramic material, which is resistant to high temperature and wear, and the inner surface is treated with an anti-stick coating. The anti-stick coating treatment is a prior art in this field and will not be described in detail here. The weld tracking sensor 103 is installed at the front end of the robot arm 101 close to the water-cooled welding gun 102, and can monitor the position, width and other parameters of the weld in real time, with a monitoring accuracy of up to 0.01mm. For example, when welding a large-diameter consumable electrode 15, the sensor can accurately capture subtle changes in the weld and provide an accurate adjustment basis for the welding robot 1.

[0031] Before welding, the robot arm 101 drives the water-cooled welding gun 102 and the weld tracking sensor 103 to move above the welding starting position. The sensor performs a preliminary scan on the weld, obtains the initial state information of the weld such as the position and groove shape, and transmits it to the control system. During the welding process, the sensor continuously monitors the weld. Once a deviation in the weld is detected, such as a weld offset caused by thermal deformation of the electrode, the deviation data is immediately transmitted to the control system of the welding robot 1. According to the deviation data, the control system drives the robot arm 101 to adjust the position, posture and welding parameters of the water-cooled welding gun 102 in real time, such as welding speed and wire feeding speed, to ensure that the welding gun is always aligned with the center of the weld for high-quality welding. The multi-degree-of-freedom robot arm 101 can make the welding gun highly flexible, adapt to welds of various complex shapes, and meet the welding requirements of electrodes of different specifications. The efficient water-cooled welding gun 102 ensures the stability of the welding process, avoids fluctuations in welding quality caused by overheating of the welding gun, prolongs the continuous welding time, and improves production efficiency. The high-precision weld tracking sensor 103 realizes real-time monitoring and adaptive adjustment of the welding process, effectively overcomes the influence of factors such as electrode thermal deformation and tooling accuracy on the weld quality, and significantly improves the welding quality.

[0032] Furthermore, it also includes a robot control cabinet 6, which is arranged on one side of the welding robot 1 and is electrically connected to the robot arm 101; a water-cooled welding machine control cabinet 7 is arranged on one side of the welding robot 1 and is electrically connected to the water-cooled welding gun 102; an electric control cabinet 8 is arranged on one side of the welding robot 1 and is electrically connected to the robot control cabinet 6, the water-cooled welding machine control cabinet 7 and the weld tracking sensor 103.

[0033] In the above scheme, the robot control cabinet 6 is connected to the robot arm 101 via industrial Ethernet, which is convenient for operators to program and debug according to different welding processes. The electric control cabinet 8 is connected to the robot control cabinet 6, the water-cooled welding machine control cabinet 7 and the weld tracking sensor 103 via cables to ensure the stability of signal transmission. The operator pre-sets the motion trajectory, welding speed, welding current and other process parameters of the welding robot 1 on the robot control cabinet 6 according to the parameters of the consumable electrode 15 and the dummy electrode 16. During the welding process, the weld tracking sensor 103 transmits the collected weld information to the electric control cabinet 8, which analyzes and processes the information. On the one hand, it sends instructions to the robot control cabinet 6 to adjust the action of the robot arm 101; on the other hand, it sends instructions to the water-cooled welding machine control cabinet 7 to adjust the welding current, voltage and other parameters in real time. The water-cooled welding machine control cabinet 7 outputs stable current and voltage according to the instructions of the electric control cabinet 8 to provide energy for welding, and at the same time feeds back its own working status information such as temperature and actual current value to the electric control cabinet 8 to ensure the coordinated and stable operation of the entire welding system. The robot control cabinet 6 is used to control the motion of the welding robot 1, which ensures the accurate execution of the complex actions of the welding robot 1 and improves the degree of automation and accuracy of welding.

[0034] Furthermore, it also includes a track 9, which is laid on the front side of the robot arm 101, and a plurality of roller frames 2 are slidably arranged on the track 9.

[0035] In the above scheme, the track 9 is made of I-beam, and the roller frame 2 can flexibly adjust the spacing on the track 9 according to the working position of the welding robot 1 to adapt to different welding requirements. During installation, the track 9 is fixed on the welding workbench according to the preset horizontal and vertical requirements. Before welding, according to the length of the consumable electrode 15 and the dummy electrode 16, the roller frame 2 is pushed to move on the track 9 through an automated device, and the spacing between the roller frames 2 is adjusted to support the electrodes. During the welding process, as the welding position changes, the roller frame 2 can slowly slide on the track 9 according to the control system instructions, drive the electrode to move, and ensure that the welding robot 1 is always in the best welding position.

[0036] Furthermore, the roller frame 2 includes a movable frame 201, which is slidably arranged on the track 9; an auxiliary cross bar 202 is arranged on the movable frame 201, and both ends of the auxiliary cross bar 202 slide against the outer wall of the track 9, and the auxiliary cross bar 202 is used to limit the movable frame 201 in a direction perpendicular to the track 9; a drive motor 203 is arranged on the movable frame 201, and the drive motor 203 is used to drive the movable frame 201 to move along the track 9.

[0037] In the above scheme, the pulley at the bottom of the mobile frame 201 cooperates with the track 9, and the auxiliary cross bar 202 installed on the side, the cross bar and the outer wall of the track 9 are in rolling contact, which can achieve limiting. The driving motor 203 drives the mobile frame 201 to move on the track 9. When starting, the control system sends a moving instruction to the driving motor 203, and the driving motor 203 causes the mobile frame 201 to start moving along the track 9. During the movement, the two ends of the auxiliary cross bar 202 ensure the stability of the mobile frame 201 perpendicular to the direction of the track 9 to prevent it from deflecting. When the mobile frame 201 reaches the predetermined position, the driving motor 203 stops rotating, and the mobile frame 201 is fixed on the track 9 by its own positioning device such as the positioning pin and the positioning hole, waiting for the next operation.

[0038] Furthermore, it also includes a blocking column 10, which has a plurality of blocking columns 10, and the plurality of blocking columns 10 are respectively arranged at both ends of the track 9; the abutment block 11 is arranged on the end surface of the movable frame 201, and after the movable frame 201 moves to one end of the track 9, the abutment block 11 abuts against the blocking column 10.

[0039] In the above scheme, when the roller frame 2 needs to move to one end of the track 9, the drive motor 203 drives it forward. As the mobile frame 201 approaches the end of the track 9, the operator or the control system monitors its position through the sensor. When the mobile frame 201 is about to reach the end, the drive motor 203 gradually slows down until the abutment block 11 lightly contacts the stop column 10. At this time, the mobile frame 201 stops moving and the precise positioning is completed. If the roller frame 2 needs to move in the opposite direction, the drive motor 203 reverses and drives the mobile frame 201 to leave the stop column 10 and move in the other direction. The combination of the stop column 10 and the abutment block 11 provides a reliable end limit for the roller frame 2, preventing the roller frame 2 from sliding out of the track 9 and ensuring the safety of the equipment.

[0040] Furthermore, it also includes a smoke adsorption box 17, which is arranged on the side of the sliding seat 1202 away from the hammer 13, and the bottom of the smoke adsorption box is provided with a smoke exhaust port 1701, and the smoke exhaust port 1701 is externally connected to a smoke exhaust pipe; the extension tube 18 is arc-shaped, and the extension tube 18 has a plurality of air inlets 1801, and the extension tube 18 is slidably arranged on the smoke adsorption box 17, and the air inlet 1801 is connected to the smoke adsorption box 17; the rotating adsorber 19 is rotatably sleeved on the extension tube 18, and the rotating adsorber 19 has a plurality of adsorption heads 1901, and the plurality of adsorption heads 1901 are all connected to the smoke adsorber 19; there are a plurality of blades 21, and the plurality of blades 21 are arranged on the inner wall of the rotating adsorber 19 at intervals.

[0041] In the above scheme, the fume adsorption box 17 is arranged at a position far away from the hammer 13. Specifically, a negative pressure fan is arranged in the middle of the inner side of the fume adsorption box 17. The fume exhaust port 1701 arranged at the bottom of the fume adsorption box 17 is connected to the negative pressure fan. A deflectable baffle is arranged at the fume exhaust port 1701, and the baffle can control the opening and closing of the fume exhaust port 1701. Moreover, a soft fume exhaust pipe is installed on the fume exhaust port 1701, so that the fume can be discharged to a place where the fume can be centrally treated. Most importantly, an extension tube 18 is installed on the fume adsorption box 17. The extension tube 18 is in an arc shape that bends upward. The curvature of the extension tube 18 is preferably the same as or similar to that of the consumable electrode 15. In this way, during welding, the fume generated by welding that originally drifts upward will be directly sucked into the extension tube 18. The fume enters the extension tube through the air inlet 1801 and then enters the fume adsorption box 17, which can prevent the fume from drifting. It should be noted that a self-rotating rotating adsorber 19 is also provided on the tube body of the extension tube 18. Specifically, the extension tube 18 is divided into two sections, with a gap between the two sections, and the rotating adsorber 19 is rotatably installed in the gap, and blades are welded at intervals on the inner wall of the rotating adsorber 19. When the flue gas flows at a high speed in the adsorption tube 18, the blades are driven to rotate, thereby realizing the rotation of the rotating adsorber 19, so that the flue gas drifting to different positions can be cleaned up, and the adsorption effect of the flue gas can be improved.

[0042] Furthermore, it also includes a roller 20 , which is rotatably disposed on the flue gas adsorption box 17 , one side of the roller 20 abuts against the outer wall of the extension tube 18 , and the other end of the roller 20 can abut against the consumable electrode 15 .

[0043] Reference Fig.12 The extension tube 18 is provided with a square hole at a position located inside the fume adsorption box 17, and the extension tube 18 is directly connected to the fume adsorption box 17 through the square hole. In addition, a roller 20 is provided on the top outer wall of the extension tube 18, and the roller 20 can choose whether to abut against the consumable electrode 15. When the consumable electrode 15 rotates clockwise for welding, the roller 20 will rotate counterclockwise, and the extension tube 18 will also rotate slowly at this time to fully absorb the fume during welding. It should be noted that the square hole must always be in the fume adsorption box 17, so every time the extension tube 18 rotates to a certain position, the extension tube 18 needs to be reset. The position-adjustable adsorption method can greatly improve the fume adsorption effect, and it is also convenient for accurate welding.

[0044] Furthermore, the hammer 13 includes a mounting seat 131, which is arranged on the sliding seat 1202; a support 132 is arranged on a diagonal rod 136 on the mounting frame, which is arranged on the outer wall of the support 132; one end of a hammer rod 133 is hinged on the support 132, and a hammer head 134 is installed on the other end; the middle part of the hammer rod 133 has a connecting end 1331 and abutting end 1332; a rotating block 137 is arranged in the support 132, and the rotating block 137 abuts on the abutting end 1332. After the rotating block 137 rotates, the rotating block 137 drives the hammer rod 133 to swing back and forth; one end of a compression spring 135 is arranged on the diagonal rod 136, and the other end is arranged on the connecting end 1331. The compression spring 135 is used to provide a force for the abutting end 1332 to press against the rotating block 137.

[0045] In the above scheme, before starting, the working parameters of the driver 138 such as the number of rotation steps, speed, etc. are set in the control system according to the thickness and hardness of the oxide scale. During starting, the driver 138 receives instructions and drives the rotating block 137 to rotate. The rotating block 137 pushes the abutting end 1332 of the hammer rod 133, so that the hammer rod 133 swings around the hinge point on the support 132, and the hammer head 134 hammers the oxide scale at the connection 14. During the hammering process, the compression spring 135 always provides a force to the abutting end 1332 to press the rotating block 137, ensuring the close contact between the hammer rod 133 and the rotating block 137, and ensuring the continuity and stability of the hammering action. Targeted treatment can be carried out according to different oxide scale conditions, thereby improving the efficiency and quality of oxide scale removal.

[0046] Furthermore, it also includes a driver 138 , which is disposed on the mounting seat 131 , and the rotating block 137 is disposed on the power output end of the driver 138 .

[0047] In the above scheme, the operator selects the appropriate control mode on the operation panel of the driver 138 according to the welding process requirements and the actual situation of the electrode oxide scale, such as the speed control mode is used for the initial hammering to quickly break the oxide scale over a large area; the position control mode is used in the later stage to accurately handle the residual oxide scale. After setting the control mode, the corresponding parameters are input into the control system, and the driver 138 receives the instruction, drives the servo motor to operate according to the set parameters, drives the rotating block 137 to move, and realizes the precise hammering action of the hammer rod 133.
