Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and in particular to a welding device with fume purification function. Background Technology

[0002] In various welding operations, whether it's large-scale automated welding in industrial production or manual welding in small-scale maintenance work, the fumes generated during welding are a critical problem that urgently needs to be addressed. Welding fumes mainly consist of tiny particles, gaseous substances, and harmful gases produced during the high-temperature melting, evaporation, and condensation of metals and non-metals. These fumes not only permeate the work area, reducing air quality and posing a serious threat to the health of operators, such as causing respiratory diseases and eye irritation, but they also adhere to equipment surfaces, affecting the normal operation and lifespan of the equipment, and pollute the surrounding environment.

[0003] Firstly, while some welding equipment on the market is equipped with certain fume purification devices, most are simple in structure and have limited functionality. For example, some simple exhaust fan devices can only expel fumes from the work area and cannot effectively filter and purify the harmful components in the fumes. As a result, the gas emitted into the environment still contains a large amount of pollutants and cannot meet increasingly stringent environmental protection requirements. Moreover, this simple ventilation method is ineffective at removing fumes that have already permeated the work space and cannot quickly improve the working environment.

[0004] Secondly, some existing fume purification devices present numerous maintenance inconveniences. Some devices use fixed-installation filter components, making disassembly and replacement extremely cumbersome when the filter plates become clogged due to prolonged use. This requires specialized tools and a significant amount of time, increasing maintenance costs and hindering normal welding operations. For example, some welding equipment has filter plates installed deep inside the device, requiring the removal of multiple surrounding components, causing considerable inconvenience to operators.

[0005] Finally, most traditional fume extraction devices lack a clogging warning function. During welding, as usage time increases, the filter components gradually become clogged with particles from the fume, leading to a decrease in purification efficiency. However, due to the lack of an effective warning mechanism, operators often fail to detect the clogging in time, only noticing when the fume extraction effect significantly deteriorates or even affects welding operations. By then, the filter components may be severely clogged, requiring more time and effort for cleaning or replacement, and may even damage the device due to prolonged neglect, further increasing maintenance costs and operational risks.

A cover plate is sleeved around the upper port of the purification box, and an air outlet is opened on the upper surface of the cover plate for discharging the gas filtered by the activated carbon filter plate. A quick-release assembly connects the purification box and the cover. Both ends of the purification box are equipped with pushing components; An alarm structure is connected to the periphery of the purification box.

[0008] Preferably, the quick-assembly assembly includes a docking block fixedly installed on the lower surface of the cover plate and a through pipe connected to one side surface of the purification chamber. The docking block has a limit insertion hole on its side. A piston disc is slidably connected to the inner wall of the through pipe. A connecting rod is fixedly welded to the surface of the piston disc. A horizontal fixing plate is fixedly connected to one end of the connecting rod. Welding block one and welding block two are fixedly installed on both ends of the purification chamber. A limit insertion rod is inserted between welding block one and welding block two, and one end of the limit insertion rod is fixedly connected to the surface of the horizontal fixing plate.

[0009] Preferably, the pushing component includes a vertically formed strip groove on the end surface of the purification box, a support rod is fixedly connected between the two end walls of the strip groove, a spring is sleeved around the support rod, a T-shaped sleeve is slidably sleeved around the support rod, and the T-shaped sleeve is slidably connected to the inner wall of the strip groove, and the T-shaped sleeve is located directly below the docking block.

[0010] Preferably, the alarm structure includes an alarm fixedly installed on the side of the purification box and a connecting block fixedly welded to the end surface of the purification box. A switch button is fixedly installed on the lower surface of the connecting block. A wire is electrically connected between the alarm and the switch button. A horizontal extension plate is fixedly welded to the side of the T-shaped sleeve block and is located directly below the switch button.

[0011] Preferably, the quick-release assembly further includes a limiting ring plate fixedly installed around the limiting rod, and the limiting ring plate is located between the first welding block and the second welding block, and a spring is sleeved around the limiting rod.

[0012] Preferably, a pull handle is fixedly welded to the surface of the horizontal fixing plate, and a sealing structure is connected between the purification box and the cover plate; The sealing structure includes a sealing slot formed on the surface of the opening end of the purification box and a sealing frame fixedly installed on the lower end surface of the cover plate, wherein the sealing frame is inserted into the inner wall of the sealing slot.

[0013] Preferably, one end of the limiting rod is inserted into the inner wall of the limiting hole, and the inner diameter of the limiting hole is compatible with the outer diameter of the limiting rod.

[0014] Preferably, one end of the spring is fixedly connected to the surface of the welding block one opposite to the welding block two, and the other end of the spring is fixedly connected to the surface of the limiting ring plate opposite to the welding block one.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. By setting up a fume purification mechanism consisting of a dust collection hood, an air pump, a purification chamber, and an activated carbon filter plate, the welding fumes generated during welding operations are collected by the dust collection hood, and the air pump extracts the fumes from the dust collection hood through a duct and sends them into the purification chamber. After being filtered by the activated carbon filter plate, the clean gas is discharged from the air outlet, thus achieving the fume purification function and avoiding the impact of welding fumes on the working environment and the health of operators.

[0017] 2. By incorporating a quick-release assembly, when the activated carbon filter plate becomes clogged, the air pressure in the passage increases, pushing the piston disc and connecting rod to move. This, in turn, moves the horizontal fixing plate and the limiting rod, causing the limiting rod to be pulled out of the limiting insertion hole. At this point, the cover plate and the purification box automatically separate, facilitating cleaning or replacement of parts inside the purification box. Simultaneously, the spring mechanism ensures that after cleaning or replacement, the limiting rod automatically resets and re-inserts into the limiting insertion hole, enabling quick installation of the cover plate and the purification box and improving maintenance efficiency.

[0018] 3. By setting up an alarm structure, when the activated carbon filter plate is clogged, the cover plate is unrestricted and pushed upward by the T-shaped sleeve block, which drives the horizontal extension plate to move upward and touch the switch button. The alarm receives the signal through the wire and alarms in time, reminding the operator that the activated carbon filter plate is clogged and needs to be cleaned. This linkage design avoids the filtration effect from being deteriorated due to clogging and ensures the continuous and effective operation of the smoke purification mechanism.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figure 1-7 A welding device with fume purification function includes a robotic arm 1, an installation frame 2 mounted at the end of the robotic arm 1, a welder 3 fixedly mounted inside the installation frame 2, and a welding head 4 fixedly connected to the front of the welder 3. A fume purification mechanism is connected between the installation frame 2 and the welding head 4.

[0023] In the fume purification mechanism, a dust collection hood 5 is fixedly installed around the welding head 4, and a purification box 6 is fixedly welded to the upper surface of the mounting frame 2. Air pumps 7 are fixedly installed on both sides of the purification box 6. The inlet and outlet ends of the air pumps 7 are respectively connected to conduit 8 and conduit 9. Through holes 10 are opened on both sides of the purification box 6, corresponding to the ends of conduit 9. A limiting plate 11 is vertically welded to the inner wall of the purification box 6. An activated carbon filter plate 12 is inserted into the inner wall of the limiting plate 11, and the activated carbon filter plate 12 is slidably connected to the inner wall of the purification box 6. A cover plate 13 is sleeved around the upper port of the purification box 6. An air outlet 14 is opened on the upper surface of the cover plate 13 for the emission of gas filtered by the activated carbon filter plate 12.

[0024] A quick-release assembly connects the purification box 6 and the cover plate 13. Pushing components are installed at both ends of the purification box 6, and an alarm structure is connected to the outside of the purification box 6.

[0025] During actual welding operations, the welding fumes are collected by the dust collection hood 5. The air pump 7 extracts the fumes from the dust collection hood 5 through the first conduit 8 and sends them into the purification box 6 through the second conduit 9. After the fumes are filtered by the activated carbon filter plate 12, the clean gas is discharged from the air outlet 14, thus achieving the fume purification function.

[0026] Furthermore, the quick-assembly assembly includes a docking block 15 fixedly installed on the lower surface of the cover plate 13 and a through pipe 17 connected to one side surface of the purification chamber 6. A limiting insertion hole 16 is provided on the side of the docking block 15. The activated carbon filter plate 12 divides the internal space of the purification chamber 6 into two spaces: the through pipe 17 is located in one space, and the air outlet 14 is located in the other. A piston disc 18 is slidably connected to the inner wall of the through pipe 17. A connecting rod 19 is fixedly welded to the surface of the piston disc 18, and one end of the connecting rod 19 is fixedly connected to a horizontal fixing plate 20. Welding blocks 1 and 22 are fixedly installed on both ends of the purification chamber 6. A limiting insertion rod 23 is inserted between welding blocks 1 and 22, and one end of the limiting insertion rod 23 is fixedly connected to the surface of the horizontal fixing plate 20.

[0027] When the activated carbon filter plate 12 becomes clogged, the air pressure in the space at the position of the through pipe 17 increases, which pushes the piston plate 18 to move. The piston plate 18 drives the connecting rod 19 and the horizontal fixing plate 20 to move. The horizontal fixing plate 20 drives the limiting rod 23 to move, so that one end of the limiting rod 23 is pulled out from the inner wall of the limiting hole 16. At this time, the cover plate 13 and the purification box 6 are automatically separated, which makes it convenient to clean or replace parts inside the purification box 6.

[0028] Furthermore, the pushing component includes a vertically formed strip groove 30 on the end surface of the purification box 6, a fixed rod 31 is fixedly connected between the two end walls of the strip groove 30, a spring 32 is sleeved around the fixed rod 31, and a T-shaped sleeve 33 is slidably sleeved around the fixed rod 31, and the T-shaped sleeve 33 is slidably connected to the inner wall of the strip groove 30, and the T-shaped sleeve 33 is located directly below the docking block 15.

[0029] When the cover plate 13 is not under force, the elastic force of the second spring 32 pushes the T-shaped sleeve block 33 to slide upward on the upright rod 31. The T-shaped sleeve block 33 pushes the docking block 15 upward, thereby pushing the cover plate 13 to move upward, which facilitates the quick removal of the cover plate 13 in the later stage for maintenance of the interior of the purification box 6.

[0030] Furthermore, the alarm structure includes an alarm 26 fixedly installed on the side of the purification chamber 6 and a connecting block 27 fixedly welded to the end surface of the purification chamber 6. A switch button 28 is fixedly installed on the lower surface of the connecting block 27, and an electrical connecting wire 29 connects the alarm 26 and the switch button 28. A transverse extension plate 34 is fixedly welded to the side of the T-shaped sleeve block 33 and is located directly below the switch button 28.

[0031] When the activated carbon filter plate 12 becomes clogged, and the cover plate 13 is unrestricted and pushed upward by the T-shaped sleeve 33, the T-shaped sleeve 33 drives the horizontal extension plate 34 to move upward. The horizontal extension plate 34 touches the switch button 28, and the alarm 26 receives the signal through the wire 29 and alarms in time, reminding the operator that the activated carbon filter plate 12 is clogged and needs to be cleaned to avoid the filtration effect from deterioration.

[0032] Furthermore, the quick-release assembly also includes a limiting ring 24 fixedly installed around the limiting rod 23, and the limiting ring 24 is located between welding block 1 21 and welding block 22, and a spring 1 25 is sleeved around the limiting rod 23.

[0033] When it is necessary to disassemble the cover plate 13 and the purification chamber 6, the piston disc 18 moves, causing the limiting rod 23 to move. The limiting rod 23 then moves the limiting ring 24, compressing the spring 25. After cleaning or replacing the parts, the spring force of the spring 25 pushes the limiting ring 24 to move, causing the limiting rod 23 to reset and re-insert into the limiting hole 16, thus achieving quick installation of the cover plate 13 and the purification chamber 6.

[0034] Furthermore, a pull handle 35 is fixedly welded to the surface of the horizontal fixing plate 20, and a sealing structure is connected between the purification box 6 and the cover plate 13. The sealing structure includes a sealing slot 36 opened on the surface of the opening end of the purification box 6 and a sealing frame 37 fixedly installed on the lower end surface of the cover plate 13. The sealing frame 37 is inserted into the inner wall of the sealing slot 36.

[0035] Pulling handle 35 allows operators to manually pull the horizontal fixing plate 20, thereby controlling the movement of the limit rod 23. When installing the cover plate 13, the sealing frame 37 is inserted into the sealing slot 36, which enhances the sealing between the purification box 6 and the cover plate 13, prevents smoke leakage, and ensures the smoke purification effect.

[0036] Furthermore, one end of the limiting rod 23 is inserted into the inner wall of the limiting hole 16, and the inner diameter of the limiting hole 16 is compatible with the outer diameter of the limiting rod 23.

[0037] This design allows the limiting rod 23 to be securely inserted into the limiting hole 16, ensuring the stability of the connection between the cover plate 13 and the purification box 6. During the operation of the welding device, it prevents the cover plate 13 from shaking or falling off, ensuring the normal operation of the fume purification mechanism.

[0038] Furthermore, one end of the spring 25 is fixedly connected to the surface of the welding block 21 opposite to the welding block 22, and the other end of the spring 25 is fixedly connected to the surface of the limiting ring 24 opposite to the surface of the welding block 21.

[0039] When the limiting rod 23 moves, it causes the limiting ring 24 to compress the spring 25, which in turn generates a spring force. When a reset is required, the spring force of the spring 25 can accurately push the limiting ring 24 and the limiting rod 23 back to their original positions, ensuring the reliability and stability of the quick-assembly and disassembly assembly.

[0040] Furthermore, the upper end of spring 2 32 is fixedly connected to the lower surface of T-shaped sleeve 33, and the lower end of spring 2 32 is fixedly connected to the end wall of strip groove 30.

[0041] When the cover plate 13 is not under force, the elastic force of the second spring 32 pushes the T-shaped sleeve 33 upward, which in turn moves the docking block 15 and the cover plate 13 upward, realizing the automatic upward push of the cover plate 13 for easy and quick removal. At this time, the upward movement distance of the cover plate 13 is less than the depth to which the sealing frame 37 is inserted into the sealing slot 36, thus preventing gas leakage from the purification box 6 while the alarm 26 is sounding, achieving a better anti-pollution effect. When the cover plate 13 is installed, it presses down on the docking block 15 and the T-shaped sleeve 33, compressing the second spring 32. The second spring 32 generates a restoring force to prepare for the next removal.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
