Description

Technical Field

[0001] This invention belongs to the field of automatic welding technology, specifically relating to an automatic welding device and method for processing iron accessories for iron towers. Background Technology

[0002] As critical connecting components for infrastructure such as power and communications, the machining precision and welding quality of steel tower fittings directly affect the stability and safety of the overall structure. Traditional steel fitting welding processes primarily rely on manual operation, requiring workers to manually position the workpiece, apply solder paste, and perform the welding process. However, manual operation has significant limitations: firstly, the uniformity of solder paste application is difficult to guarantee, easily leading to insufficient weld penetration or porosity defects; secondly, the welding angle and position depend on the operator's experience, easily causing weld misalignment due to visual fatigue or operational errors; and thirdly, the fumes and spatter generated during welding pollute the working environment, posing a threat to personnel health with long-term exposure. Although some automated welding equipment has emerged in existing technologies, its functional integration and level of intelligence remain significantly insufficient. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic welding device and method for processing iron accessories for iron towers. It can improve accuracy by adaptively adjusting the welding angle and pressure feedback, and achieve full-process automation by combining an intelligent smoke exhaust system and closed-loop control, thereby reducing manual intervention and lowering maintenance costs.

[0004] The specific technical solution adopted by this invention is as follows: An automatic welding device for processing iron accessories for iron towers includes a mounting base, and a drive unit is provided inside the mounting base for fixing and transporting the iron accessories. The mounting base also has a welding section inside, which can apply paste and weld the iron accessories transported by the drive unit: A heat dissipation unit is fixedly connected to the upper part of the mounting base. The heat dissipation unit is matched with the welding position of the welding part. The heat dissipation unit is used to exhaust the fumes generated during the welding process of the welding part. A control unit is provided at the heat dissipation part, and the control unit is electrically connected to the welding part, the drive part, and the heat dissipation part. The control unit controls the coordinated operation between the components. The welding section includes a welding seat, a sliding rod, an elastic extruder, a rotating wheel, an adjusting seat, a paste spray head, a laser welding head, a paste storage tank, and a delivery pump. One end of the welding seat is fixedly connected to the mounting base. Multiple sliding rods are slidably arranged at the other end of the welding seat. The elastic extruder is disposed between the sliding rod and the welding seat. The rotating wheel is rotatably connected to the other end of the sliding rod. The adjusting seat is also rotatably disposed at the other end of the sliding rod. The paste spray head is fixedly connected to the corresponding adjusting seat. The laser welding head is fixedly connected to the corresponding adjusting seat. The paste storage tank is fixedly connected to the interior of the mounting base. The delivery pump is fixedly connected to the mounting base. The input end of the delivery pump is connected to the interior of the paste storage tank. The output end of the delivery pump is connected to the paste spray head through a pipeline.

[0005] In a preferred embodiment, one end of the adjusting seat is configured as a horizontal adjusting beam, which can contact the iron accessory.

[0006] In a preferred embodiment, an adjusting rod is provided at the other end of the adjusting seat, and an adjusting spring is provided inside the sliding rod. There are two adjusting springs, which are respectively provided on both sides of the adjusting rod.

[0007] In a preferred embodiment, the distance between the solder paste sprayed from the output end of the paste spraying head and the output port of the laser welding head is 1.5 times the welding width of the laser welding head.

[0008] In a preferred embodiment, the rotating wheel is made entirely of high manganese steel.

[0009] In a preferred embodiment, a pressure sensor is fixedly mounted on one end of the elastic extruder, and the pressure sensor is electrically connected to the control unit.

[0010] In a preferred embodiment, the drive unit includes a drive motor, a drive rod, a conveying seat, a positioning groove, and a positioning pin. The drive motor is fixedly connected to the interior of the mounting base. One end of the drive rod meshes with the output end of the drive motor via a bevel gear. The interior of the conveying seat is threadedly connected to the outer edge of the drive rod. The positioning groove is formed inside the conveying seat, and the positioning pin is fixedly disposed inside the positioning groove.

[0011] In a preferred embodiment, the heat dissipation unit includes a ventilation plate, a filter screen, a mounting bracket, and an exhaust fan. The ventilation plate is connected to the mounting base by bolts. The filter screen is fixedly disposed inside the ventilation plate. The mounting bracket is fixedly connected to the interior of the mounting base and is inclined inside the mounting base. The exhaust fan is fixedly connected to the interior of the mounting bracket.

[0012] In a preferred embodiment, the control unit integrates an operation panel and a processor, is connected to mains power, and is electrically connected to a drive motor, a delivery pump, and a laser welding head.

[0013] An automated welding method for processing iron accessories for iron towers, applied to an automated welding device for processing iron accessories for iron towers, includes the following steps: Step 1: Place the iron accessories to be welded into the positioning slots respectively; Step 2: Drive the conveyor seat into the welding section using the drive motor; Step 3: First, the iron tower accessories are connected to the paste spray nozzle of the welding part. The paste is then squeezed out to the welding position through the paste spray nozzle. Step 4: The iron tower accessories are then used in conjunction with the laser welding head of the welding section to perform laser welding on the welding position. Step 5: The heat dissipation section is opened during the welding process to expel the fumes generated during welding; Step 6: After welding is completed, drive the motor in reverse to drive the conveyor seat. The conveyor seat will move the welded iron tower accessories out of the welding position and remove the iron tower accessories.

[0014] The technical effects achieved by this invention are as follows: This invention employs a welding section design that, through the coordinated action of an adjusting seat, adjusting beam, and adjusting spring, achieves automatic angle adjustment of the paste spraying head and laser welding head. When the iron accessory enters the welding section, the adjusting beam contacts the workpiece and drives the adjusting seat to rotate, ensuring that the output ends of the paste spraying head and laser welding head are always vertically aligned with the weld seam, eliminating angle deviations caused by manual operation. The linkage design of the elastic extrusion component and pressure sensor can monitor the contact pressure between the rotating wheel and the workpiece in real time. When the pressure exceeds a preset threshold, the control unit dynamically adjusts the conveying speed of the drive unit or suspends the welding action, avoiding welding defects caused by workpiece deformation or positioning misalignment. This closed-loop control mechanism significantly improves the adaptive capability of the welding process, meeting the requirements of high-precision welding. The drive unit of this invention employs a bevel gear meshing transmission and a threaded engagement structure. The drive motor converts the rotation of the drive rod into linear displacement of the conveyor seat. The combination design of the positioning groove and positioning pin ensures that the workpiece does not deviate during conveying. The self-locking characteristic of the threaded drive prevents the conveyor seat from sliding during power failure or emergency stop, avoiding the risk of workpiece loss of control. The bevel gear transmission structure reduces power transmission loss, and the conveyor seat runs smoothly without vibration. Combined with the wear-resistant properties of the high-manganese steel rotating wheel, it can maintain the consistency of the conveying trajectory over a long period of time. This invention's heat dissipation unit guides airflow through an inclined mounting bracket, while an exhaust fan forces the discharge of welding fumes. Combined with an internal filter screen in the ventilation panel to intercept particulate matter, the fume purification efficiency reaches over 90%, effectively reducing PM2.5 concentration in the work area. The control unit integrates an operation panel and processor, allowing for preset welding parameters (such as drive speed, solder paste flow rate, and laser power) and real-time monitoring of pressure sensor feedback signals, dynamically adjusting the coordinated actions of each component. For example, when insufficient solder paste application is detected, the system automatically increases the output pressure of the delivery pump; when the laser welding head temperature is too high, the heat dissipation unit automatically increases the exhaust intensity. This closed-loop control system achieves full automation of the solder paste application, welding, and fume extraction process, reducing manual intervention and lowering equipment maintenance frequency and energy costs.

[0020] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0021] Please see Figures 1 to 13 As shown, the present invention provides an automatic welding device and method for processing iron accessories for iron towers, including a mounting base 1, and a driving unit 2 is provided inside the mounting base 1. The driving unit 2 is used for fixing and transporting iron accessories. The mounting base 1 also has a welding section 3 inside, which can apply paste and weld the iron accessories transported by the drive unit 2: The upper part of the mounting base 1 is fixedly connected to the heat dissipation part 4, which is matched with the welding position of the welding part 3. The heat dissipation part 4 is used to exhaust the fumes generated during the welding process of the welding part 3. A control unit 5 is provided at the heat dissipation part 4. The control unit 5 is electrically connected to the welding part 3, the drive part 2, and the heat dissipation part 4. The control unit 5 controls the coordinated operation between the components. Welding section 3 includes a welding seat 301, a sliding rod 302, an elastic extruder 303, a rotating wheel 304, an adjusting seat 305, a paste spraying head 306, a laser welding head 307, a paste storage tank 308, and a delivery pump 309. One end of the welding seat 301 is fixedly connected to the mounting base 1. Multiple sliding rods 302 are slidably arranged at the other end of the welding seat 301. The elastic extruder 303 is arranged between the sliding rod 302 and the welding seat 301. The rotating wheel 304 is rotatably connected to the other end of the sliding rod 302. The adjusting seat 305 is also rotatably arranged. At the other end of the sliding rod 302, the paste spraying head 306 is fixedly connected to the corresponding adjusting seat 305, and the laser welding head 307 is fixedly connected to the corresponding adjusting seat 305. The laser welding head 307 has a built-in automatic focusing module that dynamically adjusts the distance between the output end and the workpiece according to the preset welding depth. The paste storage tank 308 is fixedly connected to the interior of the mounting base 1, and the delivery pump 309 is fixedly connected to the mounting base 1. The input end of the delivery pump 309 is connected to the interior of the paste storage tank 308, and the output end of the delivery pump 309 is connected to the paste spraying head 306 through a pipe.

[0022] Specifically, the iron accessories of the tower to be welded are fixed in the positioning groove 204 of the conveying seat 203 in the drive unit 2 for positioning. Then the drive unit 2 sends the iron accessories into the welding unit 3. At this time, the adjusting seat 305 corresponding to the paste spraying head 306 first contacts the iron accessories. The adjusting seat 305 rotates due to the pressure of the iron accessories moving, so that the adjusting seat 305 drives the paste spraying head 306 to be aligned with the welding position of the iron accessories, thus completing the adjustment of the paste application position. Then the rotating wheel 304 comes into contact with the iron accessory. As the iron accessory continues to move, it can squeeze the rotating wheel 304. The rotating wheel 304 applies the squeezing force to the sliding rod 302, so that the sliding rod 302 slides inside the welding seat 301 and squeezes the elastic extrusion member 303. The elastic pressure of the elastic extrusion member 303 makes the sliding rod 302 able to drive the rotating wheel 304 to always be in contact with the welding surface of the iron accessory, adapting to the position of the welding surface of the iron accessory. Then, the control unit 5 controls the delivery pump 309 to pump the solder paste inside the paste storage tank 308 to the spray nozzle 306 for spraying, so that the solder paste can be directly applied to the welding joint of the iron fitting. As the drive unit 2 continues to drive the workpiece to move, the iron accessory comes into contact with the adjustment seat 305 corresponding to the laser welding head 307, causing the adjustment seat 305 to drive the laser welding head 307 to rotate. At this time, the output end angle of the laser welding head 307 matches the position of the solder paste application. The control unit 5 controls the laser welding head 307 to work and weld the solder paste application position. At the same time, the control unit 5 can also control the heat dissipation unit 4 to discharge the smoke and dust generated when the laser welding head 307 is working, so as to prevent the smoke and dust from blocking the output end of the laser welding head 307 and affecting the welding efficiency of the laser welding head 307. After the iron fittings are welded, the drive unit 2 retracts and the welded iron fittings are removed from the interior of the welding unit 3, and the finished product can then be taken out.

[0023] Please see Figures 4 to 6 as well as Figures 8 to 13 As shown, one end of the adjusting seat 305 is configured as a horizontal adjusting beam 3051, which can contact the iron accessory. The length of the adjusting seat 305 is slightly longer than the diameter of the rotating wheel 304, and the horizontal surface of the adjusting seat 305 matches the outer edge of the rotating wheel 304. When the adjusting seat 305 contacts the iron accessory, the end of the adjusting beam 3051 contacts the iron accessory first, so that the welding surfaces of the adjusting beam 3051 and the iron accessory are nearly parallel. This allows the adjusting seat 305 to drive the corresponding paste spraying head 306 and laser welding head 307 to rotate, so that the welding surfaces of the paste spraying head 306 and laser welding head 307 are perpendicular to the iron accessory. The angle adjustment of the paste spraying head 306 and laser welding head 307 is achieved through the linkage between the adjusting beam 3051 and the iron accessory.

[0024] Please see Figure 5 and Figure 6 As shown, an adjusting rod 3052 is provided at the other end of the adjusting seat 305. An adjusting spring 3021 is provided inside the sliding rod 302. There are two adjusting springs 3021, which are respectively provided on both sides of the adjusting rod 3052. The elastic pressure of the adjusting spring 3021 causes the adjusting spring 3021 to press the adjusting rod 3052, so that the adjusting rod 3052 drives the adjusting seat 305 to be in a horizontal corresponding state with the sliding rod 302 in a static state. This gives the adjusting seat 305 the ability to automatically return to its original position, preventing the adjusting seat 305 from tilting irreversibly after being pressed by the iron attachment, thus affecting processing efficiency.

[0025] Please see Figure 4 As shown, the distance between the solder paste sprayed from the output end of the paste spraying head 306 and the output port of the laser welding head 307 is 1.5 times the welding width of the laser welding head 307, so that there is a gap between the solder paste and the laser welding head 307, avoiding the solder paste from adhering to the laser welding head 307 and causing damage. When the laser welding head 307 is welding, the higher the energy density of the laser beam, the greater the welding depth. However, as the welding distance increases, the diameter of the laser beam gradually increases, resulting in a decrease in energy density. In order to maintain sufficient welding depth, the laser head needs to be brought close to the welding position to ensure that the laser beam can be focused in a smaller area to obtain the required energy density.

[0026] Please see Figures 4 to 6 as well as Figures 8 to 13 As shown, the rotating wheel 304 is made entirely of high manganese steel. High manganese steel has high toughness, impact resistance and wear resistance. When in contact with iron accessories, it can form a wear-resistant layer through surface deformation hardening, which can effectively resist the wear caused by frequent friction or extrusion during the welding process. This can significantly extend the service life of the rotating wheel 304, while ensuring that it maintains a stable movement trajectory during the workpiece conveying process, and avoid the decrease in welding accuracy caused by positioning deviation due to wheel wear.

[0027] Please see Figure 4 As shown, a pressure sensor is fixedly installed at one end of the elastic extrusion member 303, and the pressure sensor is electrically connected to the control unit 5. When the workpiece comes into contact with the rotating wheel 304 during the conveying process of the drive unit 2, the rotating wheel 304 drives the sliding rod 302 to rotate, causing the sliding rod 302 to squeeze the elastic extrusion member 303. The elastic pressure of the elastic extrusion member 303 is collected by the pressure sensor, and the pressure signal of the pressure sensor is transmitted to the control unit 5 in real time. The control unit dynamically adjusts the conveying speed of the drive unit 2 or suspends the welding action according to the preset pressure threshold, thereby avoiding pressure overload problems caused by workpiece deformation, positioning offset or external force interference.

[0028] Please see Figure 4 As shown, the drive unit 2 includes a drive motor 201, a drive rod 202, a conveying seat 203, a positioning groove 204, and a positioning pin 205. The drive motor 201 is fixedly connected to the interior of the mounting base 1. One end of the drive rod 202 meshes with the output end of the drive motor 201 through a bevel gear. The interior of the conveying seat 203 is threadedly connected to the outer edge of the drive rod 202. The positioning groove 204 is opened inside the conveying seat 203, and the positioning pin 205 is fixedly installed inside the positioning groove 204. The drive motor 201 meshes with the drive rod 202 via a bevel gear, transmitting power to the drive rod 202. The outer thread of the drive rod 202 engages with the internal thread of the conveyor seat 203, converting the rotational motion of the drive rod 202 into the linear movement of the conveyor seat 203. The tower accessory is placed in the positioning groove 204 of the conveyor seat 203 and fixed in position by the positioning pin 205, ensuring that the workpiece does not shift during the conveying process.

[0029] Please see Figure 2 and Figure 7 As shown, the heat dissipation part 4 includes a ventilation plate 401, a filter screen 402, a fixing frame 403, and an exhaust fan 404. The ventilation plate 401 is connected to the mounting base 1 by bolts. The filter screen 402 is fixedly installed inside the ventilation plate 401. The fixing frame 403 is fixedly connected to the inside of the mounting base 1, and the fixing frame 403 is inclined inside the mounting base 1. The exhaust fan 404 is fixedly connected to the inside of the fixing frame 403. The fumes generated during welding are transported to the ventilation plate 401 by the exhaust fan 404. Under the guidance of the inclined fixed frame 403, the inclined fixed frame 403 optimizes the exhaust path, reduces airflow resistance, and improves the efficiency of fume discharge. The fume particles are intercepted by the filter screen 402 inside the ventilation plate 401, resulting in purified gas.

[0030] Please see Figure 1 As shown, the control unit 5 integrates an operation panel and a processor. The control unit 5 connects to the mains power supply via a power interface and is equipped with a voltage regulator circuit and overload protection module to provide a stable power supply for the device. The operation panel adopts a human-machine interface design, supporting real-time setting and display of welding parameters such as drive speed, solder paste flow rate, and laser power. The processor, as the core control unit, coordinates the start, stop, and direction of the drive motor 201, the solder paste extrusion volume of the delivery pump 309, and the welding sequence of the laser welding head 307 through preset programs. The control unit 5 is electrically connected to each actuator via cables and signal lines, forming a closed-loop control system. It can dynamically adjust the coordination of drive and welding actions based on sensor feedback to ensure consistency in paste application accuracy and welding quality.

[0031] An automated welding method for processing steel accessories for iron towers, applied to the automated welding apparatus for processing steel accessories for iron towers as described in claims 1 to 9, includes the following steps: Step 1: Place the iron accessories to be welded into the positioning groove 204 respectively; Step 2: Drive the conveyor seat 203 into the welding section 3 via the drive motor 201; Step 3: The iron tower accessories are first connected to the paste spraying head 306 of the welding part 3, and the solder paste is squeezed out to the welding position through the paste spraying head 306; Step 4: The iron tower accessories then cooperate with the laser welding head 307 of the welding part 3, and the welding position is laser welded by the laser welding head 307; Step 5: Heat dissipation section 4 is opened during the welding process to expel the fumes generated during welding; Step 6: After welding is completed, drive motor 201 drives conveyor seat 203 in reverse. Conveyor seat 203 moves the welded iron tower accessories out of the position of welding part 3 and removes the iron tower accessories.

[0032] The working principle of this invention is as follows: the iron accessories of the iron tower to be welded are fixed in the positioning groove 204 of the conveying seat 203 in the drive unit 2 for positioning. Then the drive unit 2 sends the iron accessories into the welding unit 3. At this time, the adjusting seat 305 corresponding to the paste spraying head 306 first contacts the iron accessories. The adjusting seat 305 rotates due to the pressure of the iron accessories moving, so that the adjusting seat 305 drives the paste spraying head 306 to be aligned with the welding position of the iron accessories, thus completing the adjustment of the paste application position. Then the rotating wheel 304 comes into contact with the iron accessory. As the iron accessory continues to move, it can squeeze the rotating wheel 304. The rotating wheel 304 applies the squeezing force to the sliding rod 302, so that the sliding rod 302 slides inside the welding seat 301 and squeezes the elastic extrusion member 303. The elastic pressure of the elastic extrusion member 303 makes the sliding rod 302 able to drive the rotating wheel 304 to always be in contact with the welding surface of the iron accessory, adapting to the position of the welding surface of the iron accessory. Then, the control unit 5 controls the delivery pump 309 to pump the solder paste inside the paste storage tank 308 to the spray nozzle 306 for spraying, so that the solder paste can be directly applied to the welding joint of the iron fitting. As the drive unit 2 continues to drive the workpiece to move, the iron accessory comes into contact with the adjustment seat 305 corresponding to the laser welding head 307, causing the adjustment seat 305 to drive the laser welding head 307 to rotate. At this time, the output end angle of the laser welding head 307 matches the position of the solder paste application. The control unit 5 controls the laser welding head 307 to work and weld the solder paste application position. At the same time, the control unit 5 can also control the heat dissipation unit 4 to discharge the smoke and dust generated when the laser welding head 307 is working, so as to prevent the smoke and dust from blocking the output end of the laser welding head 307 and affecting the welding efficiency of the laser welding head 307. After the iron fittings are welded, the drive unit 2 retracts and the welded iron fittings are removed from the interior of the welding unit 3, and the finished product can then be taken out.

[0033] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
