Description

Technical Field

[0001] The utility model relates to the technical field of etching equipment, in particular to an etching equipment used for metal surface processing. Background Art

[0002] Metal surface etching technology is divided into two main types: wet etching and dry etching. Wet etching uses the chemical reaction between a specific solution and a thin film to remove materials, while dry etching removes part of the material through physical impact. In order to partially corrode the metal workpiece and leave the desired pattern and text, etching processing is essential. However, existing etching equipment generally requires the metal workpiece to be immersed in etching solution to achieve the etching effect. Therefore, the metal workpiece cannot be etched continuously and uninterruptedly, resulting in low work efficiency. In addition, the etched metal workpiece requires additional equipment to clean it, which is inconvenient to operate and increases the cost of the equipment. Utility Model Content
