Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to an ironing board welding processing system and method thereof. Background Art

[0002] An ironing board is a tool used for ironing clothes, usually consisting of a long strip of board and a bracket. Its design allows one to maintain a stable and comfortable posture when ironing clothes, avoiding operation directly on the ground or other unsuitable surfaces. Currently used ironing boards often adopt a liftable design, and the lifting structure requires a docking ear welded at the bottom of the ironing board to provide a rotating connection.

[0003] Since the thickness of the ironing board is relatively thin, the commonly used welding method is argon arc welding, which has high stability and a relatively flat welding surface. However, when welding with existing welding equipment, there is a high probability that dust and other impurities are attached to the surface of the welding workpiece. These impurities will cause pores and other phenomena in the welding. Therefore, the announcement number CN218694796U discloses an argon arc welding automatic welding equipment, which includes a welding equipment body, a fixed part of a driver is arranged at the left edge position of the upper end of the welding equipment body, a fixed plate is installed at the right edge position of the upper end of the welding equipment body, a fixed part of a telescopic machine is arranged at the middle position of the right end of the fixed plate, the movable part of the telescopic machine passes through the fixed plate and is connected to the movable plate, a straight cylinder is arranged at the rear of the left end of the movable plate, a piston is slidably connected in the straight cylinder, a transversely arranged fixed rod is arranged at the middle of the left end of the piston, the fixed rod extends out of the left side of the straight cylinder and is connected to the rear end of the fixed part of the driver, an air pipe with a pressure relief valve is arranged at the upper end of the straight cylinder, and one end of the air pipe is connected to the straight cylinder, and the other end of the air pipe is connected to the inlet of the Y-type pipe through a bend pipe joint.

[0004] When the welding equipment is performing welding, the movable plate moves to the left, and the straight cylinder moves to the left along the piston under the action of the fixed rod, so that the gas in the straight cylinder can be blown along the air pipe and the Y-tube toward the welding surfaces of the two workpieces, thereby cleaning the welding surfaces, improving the subsequent welding quality, and achieving the purpose of linkage between the cleaning operation and the workpiece docking operation.

[0005] However, the welding equipment uses an ordinary argon arc welding head for welding. The central control design inside the welding head is used to spray out shielding gas. A argon electrode is set in the middle of the welding head for welding. Therefore, during the welding process, the welding slag produced by welding will splash into the inside of the welding head and adhere to the inner wall of the welding head. This will affect the smoothness of the shielding gas spraying. When the shielding gas is sprayed, it will counteract the welding slag, causing the shielding gas to vibrate, thereby generating welding bubbles.

[0006] Therefore, a novel ironing board welding processing system and method can be used to solve the deficiencies of the prior art. Summary of the invention

[0007] The purpose of the present invention is to solve the problems existing in the prior art and to propose an ironing board welding processing system and method.

[0016] Preferably, the welding slag cleaning mechanism includes an air guide ring rotatably mounted on the end of the air guide cylinder, a plurality of shafts rotatably mounted on the air guide ring, each of the shafts is fixedly mounted with a scraper that cooperates with the inner wall of the air guide cylinder, a spring roll is fixedly mounted between each of the shafts and the air guide ring, and a driving mechanism that cooperates with the air guide ring is installed on the air guide cylinder.

[0017] Preferably, the driving mechanism includes an air intake box fixedly mounted on the outside of the air guide cylinder, the air intake box and the jet cylinder are connected in three phases via a plurality of air pipes, an annular turbofan rotatably mounted on the outside of the air guide cylinder and connected to the air intake box, the annular turbofan is connected to the air guide ring via a plurality of air pipes, and a pressure structure matched with a plurality of shafts is mounted on the air guide cylinder.

[0020] The present invention also provides an ironing board welding processing method, comprising the above-mentioned ironing board welding processing system, and further comprising the following steps:

[0021] S1. First, place the ironing board on the clamping assembly, then move the ironing board by moving or rotating the robot arm and the rotating table, so that the ironing board and the docking ear are against each other, and then preheat the ironing board and the docking ear by the preheating device;

[0022] S2. After preheating is completed, the position of the welding gun is adjusted by the sliding assembly so that the welding assembly on the welding gun is aligned with the welding point between the ironing board and the docking ear, and then the welding gun is locked;

[0023] S3. During welding, a protective gas is introduced into the welding assembly through a high-pressure air pipe, and then welding is performed through the welding assembly. During the welding process, the welding gun can be scraped to prevent welding slag from adhering to the inner wall of the welding gun. During the scraping process, the scraping force can be adjusted by changing the pressure of the gas in the high-pressure air pipe to achieve a better scraping effect. At the same time, during the scraping process, the surface of the scraped component can also be cleaned to prevent welding slag from adhering to the surface of the scraped component.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. When welding the ironing board and the docking ear, the ironing board welding system scrapes off the welding slag adhered to the inner wall of the gas guide tube by setting a rotatable scraper, which effectively reduces the influence of welding slag on the ventilation of the shielding gas, makes the shielding gas ventilation smoother, reduces the generation of welding bubbles, and improves the welding quality.

[0026] 2. When welding the ironing board and the docking ear, the ironing board welding processing system can use the impact force of the shielding gas to drive the scraper to rotate around the inner wall of the gas guide tube by setting the air pipe three, the air inlet box, the annular turbofan and the air guide ring. No additional driving equipment is needed. This can effectively avoid the influence of the vibration generated by the operation of the driving equipment on the welding gun, thereby improving the stability of the welding gun during operation, which is beneficial to improving the welding quality. At the same time, the shielding gas is used as the power source. The shielding gas is not only sprayed to the welding position, but also sprayed to the periphery of the welding gun to form an annular protection ring, which plays a certain cooling effect and splash prevention effect.

[0027] 3. When welding the ironing board and the docking ear, the ironing board welding processing system can utilize the pressure of the protective gas to drive the telescopic cylinder to operate by setting the air guide ring, air pipe 2, telescopic cylinder, rotating disk and shaft rod, thereby driving the shaft rod and the scraper to rotate, and is used to adjust the mortgage force between the scraper and the inner wall of the air guide cylinder, so as to scrape off welding slag with different adhesion degrees, with higher scraping efficiency and more thorough scraping, and will not cause damage to the inner wall of the air guide cylinder.

[0028] 4. When welding the ironing board and the docking ear, the ironing board welding processing system can pass the protective gas into the scraper by setting the air guide ring, gas booster, tension spring, piston plate and magnet to move the piston plate inside the scraper, and then drive the outer sleeve of the scraper that is attached to the scraper to move back and forth through the magnet, so as to clean the welding slag adhering to the scraper and improve the scraping efficiency of the scraper.

[0029] In summary, the present invention utilizes the pressure of the shielding gas as a driving source when welding between the ironing board and the docking ear, and does not require an additional driving source. This can reduce the vibration generated during cleaning and make the shielding gas spray smoother. At the same time, the pressure of the shielding gas is used to adjust the pressure between the scraper and the inner wall of the air guide tube, so that the scraper can scrape more thoroughly. In addition, the scraper can also be cleaned to improve the scraping efficiency of the scraper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Example 1: Reference Figure 1-Figure 5A ironing board welding processing system includes a base 1 and a robot arm 2 installed on the base 1. A rotating table 5 is rotatably installed at the end of the robot arm 2, and a bracket 6 is fixedly installed on the rotating table 5. The robot arm 2 and the rotating table 5 are both existing technologies, and their working principles and structures are not described in detail here.

[0052] The clamping part is installed on the bracket 6 , and is used to clamp and fix the ironing board to be welded for welding and feeding operations. The clamping part includes a clamping assembly 3 fixedly installed on the bracket 6 .

[0053] The clamping assembly 3 includes two clamps 11 rotatably mounted on the bracket 6, and a linkage is installed between the two clamps 11; the linkage is a common linkage device, which is composed of a rotating shaft and a gear. The two clamps 11 are fixedly connected to the rotating shafts respectively, and the rotating shafts are rotatably connected to the bracket 6. A mutually meshing gear is fixedly installed on the two rotating shafts. When one of the clamps 11 rotates, it will drive the other clamp 11 to rotate in the opposite direction through the gear to achieve the clamping purpose.

[0054] A hydraulic rod 12 is fixedly mounted on the bracket 6, and a driving end of the hydraulic rod 12 is rotatably connected to one of the clamps 11. A control module 10 matching the hydraulic rod 12 is fixedly mounted on the bracket 6, and the driving end of the hydraulic rod 12 drives the clamp 11 to rotate around the rotating axis. The control module 10 is an existing device that can be programmed to automatically control the operation of the hydraulic rod 12.

[0055] The ends of the two clamps 11 are rotatably mounted with a disc through a universal ball, and the two discs are provided with anti-skid grooves on the sides close to each other; the purpose of using the rotating disc here is to clamp and fix ironing boards of different thicknesses, and the anti-skid grooves on the surface of the disc can improve the stability of clamping and fixing.

[0056] Embodiment 2: This embodiment is different from the embodiment 1 in that: Figure 1-Figure 4 , Figure 6-Figure 18 , welding part, mounted on the bracket 6 through a sliding assembly, used for welding the ironing board;

[0057] The sliding assembly includes a slide rail 7 fixedly mounted on a bracket 6, a sliding connecting block 8 is slidably mounted on the slide rail 7, the welding gun 4 and the sliding connecting block 8 are rotationally connected, the welding gun 4 and the sliding connecting block 8 are fixed by a docking bolt 9, and the sliding connecting block 8 and the slide rail 7 are fixed by a locking bolt.

[0058] The sliding connection block 8 is provided with a threaded groove that matches the docking bolt 9. By rotating the docking bolt 9, the angle of the welding gun 4 can be locked, and the locking bolt locks the position of the sliding connection block 8 on the slide rail 7, thereby adjusting the position and angle of the welding gun 4 to ensure that the welding gun 4 is aligned with the welding position.

[0059] The welding part includes a welding gun 4, which is composed of a shell 13, a high-pressure air pipe 14, a gun body 15 and a welding assembly 16. The shell 13 is made of metal material, and the outside of the shell 13 is wrapped with a rubber protective sleeve to play a role in heat insulation.

[0060] The high-pressure air pipe 14 is used to inject shielding gas into the welding gun 4, the gun body 15 is used for the operator to control, the welding assembly 16 is used for spraying shielding gas and heating welding of the ironing board, the high-pressure air pipe 14 is connected to the welding assembly 16, and the high-pressure air pipe 14 is connected to the external gas source.

[0061] The welding assembly 16 includes a welding head 17, on which an air inlet pipe 19 is fixedly installed, the air inlet pipe 19 is connected to the high-pressure air pipe 14, a jet cylinder 27 connected to the air inlet pipe 19 is fixedly installed inside the welding head 17, a gas guide cylinder 20 is fixedly installed on the welding head 17, a black electrode 25 is fixedly installed inside the gas guide cylinder 20, a sealing ring 28 is fixedly installed between the gas guide cylinder 20 and the jet cylinder 27, and a welding slag cleaning mechanism that cooperates with the gas guide cylinder 20 is installed at the end of the gas guide cylinder 20.

[0062] The high-pressure air pipe 14 passes the shielding gas into the air inlet pipe 19, and then introduces it into the air jet 27 through the air inlet pipe 19. The air jet 27 can spray the shielding gas accurately to the welding position. The welding electrode 25 is connected to an external power supply, and welding is performed by heating the welding electrode 25. During welding, the welding electrode 25 needs to be perpendicular to the weld.

[0063] For heat insulation, a gap is provided between the jet cylinder 27 and the gas guide cylinder 20. In order to prevent the Outback gas from entering the gap and causing gas reflux, a high-temperature resistant sealing ring 28 is required to seal the gap. The sealing ring 28 adopts a metal mechanical sealing ring (which is an existing technology and will not be elaborated here).

[0064] The welding slag cleaning mechanism includes an air guide ring 30 rotatably mounted on the end of the air guide cylinder 20, and a plurality of shafts 35 are rotatably mounted on the air guide ring 30. A scraper 26 matching the inner wall of the air guide cylinder 20 is fixedly mounted on each shaft 35, and a spring roll 36 is fixedly mounted between each shaft 35 and the air guide ring 30. A driving mechanism matching the air guide ring 30 is installed on the air guide cylinder 20.

[0065] The air guide ring 30 rotates on the air guide cylinder 20, which drives the scraper 26 rotatably connected thereto to make a circular motion around the center point of the air guide cylinder 20. The scraper 26 is rotatably connected to the air guide ring 30 through a shaft 35, and a spring roll 36 is also provided. Under the action of the spring roll 36, the end of the scraper 26 abuts against the inner wall of the air guide cylinder 20, thereby cleaning the welding slag on the inner wall.

[0066] The scraper 26 has a trapezoidal cross-section, and the bottom side of the trapezoid is an arc, which fits perfectly with the inner wall of the air guide tube 20. The purpose of setting the trapezoidal shape is to allow the scraped welding slag to climb onto the scraper 26 along the inclined side of the trapezoid, so as to facilitate the cleaning of the scraper 26 later.

[0067] The driving mechanism includes an air intake box 21 fixedly mounted on the outside of the air guide cylinder 20. The air intake box 21 is connected to the jet cylinder 27 via a plurality of air pipes 33. An annular turbofan 22 rotatably mounted on the outside of the air guide cylinder 20 and connected to the air intake box 21 is connected to the air guide ring 30 via a plurality of air pipes 31. A pressure structure matched with a plurality of shafts 35 is mounted on the air guide cylinder 20.

[0068] The high-pressure gas in the air guide cylinder 20 will enter the air intake box 21 through the air pipe three 33, and the air intake box 21 will spray the protective gas into the annular turbofan 22 to make the annular turbofan 22 rotate. The rotation of the annular turbofan 22 drives the air guide ring 30 to rotate through the air pipe one 31, so that the scraper 26 can make a circular motion around the central axis of the air guide cylinder 20 (the reason why the air jet from the air intake box 21 drives the annular turbofan 22 to rotate is because there are many inclined baffles inside the annular turbofan 22. The gas impact on the inclined baffles will generate pressure, and the pressure will be divided into a horizontal component and a vertical component by the inclined baffles. The horizontal component will push the annular turbofan 22 to rotate. Since the annular turbofan 22 and the air guide cylinder 20 are connected in rotation, the vertical thrust cannot drive the annular turbofan 22 to move).

[0069] The pressure structure includes an annular air collecting box 23 fixedly connected to the annular turbofan 22, a piston ring 29 is slidably installed inside the air collecting box 23, a plurality of air pipes 32 are fixedly connected to the air collecting box 23, a plurality of arc-shaped telescopic cylinders 37 are fixedly installed on the air guide ring 30, each air pipe 32 is connected to the corresponding telescopic cylinder 37, a rotating disk 34 is fixedly installed on the shaft 35, a push block is fixedly installed on the rotating disk 34, the telescopic end of the telescopic cylinder 37 is fixedly connected to the push block, and a cleaning component is installed between the air guide ring 30 and the corresponding scraper 26.

[0070] Part of the gas in the annular turbofan 22 will enter the gas collecting box 23, and part of it will overflow from the top of the gas collecting box 23, thus forming an annular gas path for heat dissipation and splash prevention;

[0071] The gas entering the air collecting box 23 will push the piston ring 29 to move in the air collecting box 23 toward the bottom of the air collecting box 23. At this time, the air in the air collecting box 23 is compressed, which will press the air into the air pipe 2 32, and then press the air into the telescopic cylinder 37 through the air pipe 2 32 to extend the telescopic end of the telescopic cylinder 37. Since the telescopic cylinder 37 is arc-shaped, its arc is concentric with the shaft rod 35. Therefore, the extension of the telescopic end of the telescopic cylinder 37 will push the rotating disk 34 to rotate under the action of the push block, thereby driving the shaft rod 35 and the scraper 26 to rotate, so that the tip of the scraper 26 is against the inner wall of the air guide tube 20, thereby increasing the pressing force to improve the scraping efficiency.

[0072] The cleaning component includes a sleeve 38 slidably mounted on the scraper 26, a groove body is opened inside the scraper 26, a gas booster is fixedly mounted inside the air guide ring 30, an air pipe four 39 is fixedly connected to the gas booster, the air pipe four 39 passes through the scraper 26 and extends into the groove body, a piston plate 41 is slidably mounted in the groove body, a tension spring 40 is fixedly mounted between the piston plate 41 and the inner wall of the scraper 26, a magnet 42 matching the sleeve 38 is fixedly mounted on the side of the piston plate 41 away from the tension spring 40, a protective cover 24 is fixedly mounted on the air guide ring 30, and an exhaust valve is fixedly mounted on the air pipe four 39.

[0073] The shielding gas in the air guide ring 30 will enter the scraper 26 through the air pipe 439. As the shielding gas increases, the groove in the scraper 26 will push the piston plate 41 to move, thereby driving the magnet 42 to move. The magnet 42 will drive the sliding sleeve 38 outside the scraper 26 to move through suction, so that the sliding sleeve 38 moves on the scraper 26, thereby cleaning the welding slag adhered to the scraper 26.

[0074] When the sleeve 38 is reset, the protective gas inside the scraper 26 is discharged through the exhaust valve. At this time, the protective gas inside the scraper 26 is reduced, the pressure is reduced, and it is reset under the action of the tension spring 40 (when the pressure inside the scraper 26 increases, the tension spring 40 is in an extended state). The function of the protective cover 24 is to protect the air pipe 439, and also to make the outlet of the air guide cylinder 20 smooth, so as to ensure smooth injection of the protective gas.

[0075] The specific operation steps of this device are as follows:

[0076] First, the ironing board is placed on the clamping assembly 3, and then the ironing board is moved by the movement or rotation of the robot arm 2 and the rotating table 5, so that the ironing board and the docking ear are abutted, and then the ironing board and the docking ear are preheated by the preheating device;

[0077] After preheating is completed, the position of the welding gun 4 is adjusted by the sliding assembly so that the welding assembly 16 on the welding gun 4 is aligned with the welding point between the ironing board and the docking ear, and then the welding gun 4 is locked;

[0078] During welding, a shielding gas is introduced into the welding assembly 16 through the high-pressure air pipe 14, and then welding is performed through the welding assembly 16. During the welding process, the welding gun 4 can be scraped to prevent welding slag from adhering to the inner wall of the welding gun 4. During the scraping process, the scraping force can be adjusted by changing the pressure of the gas in the high-pressure air pipe 14 to achieve a better scraping effect. At the same time, during the scraping process, the surface of the scraping component can also be cleaned to prevent welding slag from adhering to the surface of the scraped component.

[0079] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
