Description

Technical Field

[0001] The invention relates to the technical field of cleaning packaging barrels for electronic-grade chemicals, in particular to a method for cleaning electronic-grade packaging barrels. Background Art

[0002] With the rapid development of the global semiconductor industry, the importance of electronic-grade chemicals as key materials has become increasingly prominent. These chemicals are mainly used in process steps such as etching and cleaning, and are essential to ensuring the quality and performance of semiconductor devices. Therefore, the market demand for electronic-grade chemicals has risen sharply, which has also driven the growth of demand for their special packaging barrels. Due to their extremely high purity requirements, the introduction of impurities must be strictly controlled during production and use. In order to meet this high standard, the packaging barrels must not only have good sealing and corrosion resistance, but also must undergo a strict cleaning procedure before and after each use to remove any possible contaminants. Traditionally, such packaging barrels are mostly imported, costly, and are usually recycled multiple times to reduce costs and improve economic benefits.

[0003] In the early days, the industry generally adopted a semi-automatic machine cleaning method, that is, the operator manually placed the packaging barrel in the cleaning equipment, repeatedly rinsed it by pouring clean water or a specific solvent, and then manually shook it to help remove the residual liquid. However, this method has many shortcomings: 1. The whole process takes a long time and cannot meet the needs of large-scale production; 2. Highly dependent on manual operation, which increases labor costs; 3. Operators are directly exposed to harmful chemicals, which poses a health and safety hazard. Due to the influence of human factors, it is difficult to achieve consistent cleaning results, resulting in large fluctuations in product quality. Summary of the invention
