Description

Technical Field

[0001] This utility model relates to the field of battery casing spray gun technology, specifically a special spray gun for battery casing spraying with an angle fine-tuning mechanism. Background Technology

[0002] In the battery manufacturing process, the coating process for the battery casing is crucial. Coating not only provides protection for the battery casing, enhancing its corrosion and abrasion resistance and extending battery life, but also optimizes the battery's appearance to some extent. With the rapid development of the battery industry, the requirements for the quality and efficiency of battery casing coating are increasing, making precise and efficient coating a goal pursued by the industry.

[0003] However, the currently used battery casing spray guns have many shortcomings. On the one hand, conventional spray guns have a fixed angle, making it difficult to flexibly adapt to the complex and diverse shapes of battery casings. When facing special curved surfaces or corners, it is impossible to achieve uniform and comprehensive spraying. On the other hand, when attempting to manually adjust the spray gun angle, it is very easy to cause shaking, which will seriously affect the uniformity of the spraying effect, resulting in uneven coating thickness, and thus affecting the protective performance and appearance quality of the battery casing.
