During welding, the workpiece is first preheated by the preheating component 4, and the workpiece to be welded is cleaned by the cleaning component 2. The cleaning process is performed at the designated location. The collection component 3 collects the cleaned impurities and particles. After placing the workpiece in the designated position, the fixing ring 22 slides and moves upward in the middle of the fixing rod 21. The fixing ring 22 is fixed in the middle of the fixing rod 21 by the first bolt 23, so that the ends of the brush bristles 25 are in contact with the workpiece surface. When the workpiece is rotated, the brush bristles 25 clean the impurities and oil stains on the workpiece surface. After cleaning, the workpiece is welded by the welding module 10. During the welding process, the workpiece continues to rotate, so that the welding chips are removed at the same time. After the welding chips are cleaned, they enter the collection tank 26. Through the above structure, the brush bristles 25 can closely adhere to the workpiece surface, so that the brush bristles 25 are in uniform contact with the workpiece, effectively removing the oxide layer, oil stains and impurities on the workpiece surface, reducing the welding defects caused by these impurities in the workpiece weld, maintaining the consistency of the weld, reducing the rework and scrap rate after workpiece welding, effectively reducing the preparation time for cleaning the workpiece separately, and can adapt to workpieces of different diameters or thicknesses, so that the entire surface of the workpiece is cleaned evenly, reducing omissions or repeated cleaning.
[0024] like Figures 1 to 4As shown, the collecting component 3 includes a through groove 31; the through groove 31 is formed at the bottom of the cleaning plate 24; two first locking blocks 32 are fixedly connected to the bottom of the cleaning plate 24; the first locking blocks 32 are arranged opposite each other; a second locking block 34 is installed in the middle of the first locking blocks 32; a collecting box 33 is fixedly connected to the middle of the two second locking blocks 34; during operation, after the cleaning plate 24 is moved to the bottom of the workpiece, the collecting box 33 is moved upward from the bottom of the cleaning plate 24, and the second locking blocks 34 on both sides of the collecting box 33 pass through the first locking blocks 32 on both sides. The first locking blocks 32 are flexibly arranged. When the second locking blocks 34 press against the first locking blocks 32, the first locking blocks 32 are pushed open to both sides by pressure. The first locking block 32 enters the second locking block 34 and locks the first locking block 32 in place. At this time, the collection box 33 is fixed in the middle of the cleaning plate 24. The debris inside the collection groove 26 enters the collection box 33 through the through groove 31 and is collected. After collection, the collection box 33 is taken out for subsequent processing.

The airflow is discharged into the exhaust duct 44, and then enters the middle of the cavity 41 through the connecting pipe 43. The heat generated on the surface of the heating rod 42 adds to the airflow. The heated airflow is discharged from the two sets of exhaust holes 46. The hot airflow blows onto the surface of the workpiece to preheat it. When preheating is not required, the heating rod 42 is turned off, and the cooling airflow blows onto the surface of the workpiece. The above structure can preheat the welding area of the workpiece, reduce the temperature difference generated during the welding process, effectively reduce thermal stress, reduce defects such as cracks or porosity, thereby improving the welding quality. It can also control the cooling rate of the weld seam and cool the workpiece according to actual needs.
[0026] like Figures 2 to 4As shown, two baffles 5 are fixed to the inner wall of the cleaning plate 24; the two baffles 5 are arranged opposite each other; the baffles 5 are set on both sides of the collection tank 26; during operation, when the workpiece surface and welding slag are cleaned by the brush bristles 25, the slag falls to the bottom, and the two baffles 5 block the splashing slag, while the slag accurately enters the collection tank 26 along the side wall of the baffles 5. The above structure can effectively guide the welding slag into the collection box 33, which can reduce the welding slag scattered in the working area, keep the equipment and working environment clean, effectively reduce the welding slag scattered on the workpiece surface or welding area, reduce the impact on the welding quality of the workpiece, facilitate centralized treatment or reuse, and reduce material waste.

The above structure makes the replacement of the brush bristles 25 more convenient, allowing the brush bristles 25 to be quickly replaced according to different workpieces or welding requirements, improving the flexibility and adaptability of the equipment, and effectively maintaining a good cleaning effect.
[0028] like Figures 2 to 4 As shown, a filter screen 7 is installed in the middle of the exhaust hole 46; the filter screen 7 is fixed in the middle of the exhaust hole 46; during operation, the welding slag is blocked by the filter screen 7, preventing the welding slag from entering the interior of the cleaning plate 24. The above structure can effectively reduce the amount of welding slag entering the interior of the cleaning plate 24, reduce the cleaning difficulties caused by the accumulation of welding slag, and keep the interior of the cleaning plate 24 clean.
[0029] During operation, the workpiece is placed and fixed on the mounting module 11. The welding module 10 is controlled to weld the workpiece seam, while the mounting module 11 rotates the workpiece. During welding, the workpiece is first preheated by the preheating component 4, and the area to be welded is cleaned by the cleaning component 2. The collection component 3 collects the cleaned impurities and particles. After placing the workpiece in the designated position, the fixing ring 22 slides and moves upward in the middle of the fixing rod 21. The fixing ring 22 is fixed in the middle of the fixing rod 21 by the first bolt 23, so that the ends of the bristles 25 are in contact with the workpiece surface. The workpiece is then rotated... The brush 25 cleans impurities and oil stains from the workpiece surface. After cleaning, the workpiece is welded via the welding module 10. During welding, the workpiece rotates continuously, removing welding slag. The slag enters the collection tank 26. After the cleaning plate 24 is moved to the bottom of the workpiece, the collection box 33 is moved upward from the bottom of the cleaning plate 24. The second locking blocks 34 on both sides of the collection box 33 pass through the first locking blocks 32 on both sides. The first locking blocks 32 are flexible. When the second locking blocks 34 press against the first locking blocks 32, the first locking blocks 32 are pushed open to both sides by the pressure. The first locking blocks 32 enter the second locking block 26. Inside the second locking block 34, the first locking block 32 is locked in place by the second locking block 34. At this time, the collection box 33 is fixed in the middle of the cleaning plate 24. The debris inside the collection groove 26 enters the collection box 33 through the through groove 31 and is collected. After collection is completed, the collection box 33 is removed for subsequent processing. After the workpiece is fixed, the control fan 45 and heating rod 42 are turned on. The fan 45 discharges airflow into the exhaust pipe 44. The airflow then enters the middle of the cavity 41 through the connecting pipe 43. The heat generated on the surface of the heating rod 42 adds to the airflow. The heated airflow is discharged from the two sets of exhaust holes 46, and the hot airflow blows onto the surface of the workpiece. The workpiece is preheated. When preheating is not required, the heating rod 42 is turned off, and the cooling airflow blows onto the workpiece surface. When the workpiece surface and welding slag are cleaned by the brush 25, the slag falls to the bottom and is blocked by the two baffles 5. The slag accurately enters the collection tank 26 along the side wall of the baffle 5. After the brush 25 has been used for a period of time, it is replaced. The two second bolts 62 are unscrewed from the middle of the base plate 61 and the cleaning plate 24, thereby separating the brush 25 from the cleaning plate 24. During the welding process, the welding slag is blocked by the filter screen 7, preventing the welding slag from entering the interior of the cleaning plate 24.
