[0002] During the welding process of metal materials, a layer of oxide scale, commonly known as "black scale", often forms on the weld and its heat-affected zone. This black scale not only affects the appearance quality of the material, but may also have adverse effects on the mechanical properties and subsequent processing of the material. Traditional methods of removing black scale mainly rely on manual grinding or mechanical tapping, which have problems such as high labor intensity, low efficiency, incomplete removal, or easy to cause secondary damage. With the development of industrial automation technology, the demand for automated, efficient, and environmentally friendly black scale removal equipment is growing.

[0003] The patent authorization number is CN 213378301 U, which discloses a device for removing black skin from welding. The device can automatically knock the black skin on the surface of the parts continuously to make the black skin fall off the parts quickly, and then continuously grind the welding joints with a grinding wheel to make the welding joints smoother, thereby realizing the automatic removal of black skin on the surface of metal materials. However, there are still some problems in the actual use of the above device: after the hammer block knocks the black skin off, the position of the material needs to be manually changed for grinding, and the hammering and grinding processes cannot be replaced in time and work continuously, which will affect the efficiency of black skin removal. Moreover, the weld of the metal plate generally has a certain length. In the process of removing the black skin, the position of the hammering and grinding needs to be adjusted in time, and the above device cannot automatically complete this operation, which has certain defects.

First, the metal sheet is placed on a workbench 1, and the weld is located below the black skin removal component 6. Then, the hydraulic cylinder 4 is used to control the black skin removal component 6 to move downward. When the grinding roller 62 contacts the surface of the metal sheet, the motor 1 31 and the motor 2 612 are controlled to operate. The motor 1 31 drives the screw 32 to rotate. Under the cooperation of the screw 32 and the screw sleeve 33, the mounting seat 34 and the black skin removal component 6 are driven to move on the black skin surface of the metal sheet. At the same time, the transmission gear 611 and the gear With the transmission cooperation of the reduction box 610, the turntable 64 and the grinding roller 62 are driven to rotate at different speeds at the same time.
