Description

Technical Field

[0001] The utility model relates to the technical field of etching equipment, in particular to a micro-etching spray device. Background Art

[0002] In industrial manufacturing, surface treatment such as etching is crucial to improving material performance and appearance. Etching liquid removes specific parts of the material surface through chemical action to achieve precise pattern design or improve surface texture. However, traditional etching processes face multiple technical challenges, especially in post-etching cleaning and equipment maintenance.

[0003] Common problems include the erosion of the etching solution on the equipment, especially the long-term damage to the nozzle and flow control valve. If the corrosive chemical components in the etching solution are not removed thoroughly and in a timely manner, the residue will corrode the nozzle and valve, affecting the accuracy and service life of the equipment. In addition, the residual etching solution may also affect the quality of the subsequent processed workpieces, resulting in reduced production efficiency and product quality.

This design not only improves production efficiency and product quality, but also reduces maintenance costs and potential equipment failures, providing users with a cost-effective solution.
