Description

Technical Field

[0001] The invention relates to the technical field of aircraft automatic spraying, in particular to an automatic spraying device for small aircraft parts. Background Art

[0002] With the rapid development of the global aviation manufacturing industry, the demand for aircraft manufacturing and maintenance is increasing, and the requirements for coating production efficiency and quality are also constantly improving. The surface coating of aviation products is not only a key measure to protect the body materials from corrosion and environmental erosion, but also an important link to improve flight performance and aesthetics. Aircraft manufacturing is a typical multi-variety, small-batch production model, especially for small parts, which are numerous and complex in structure. The traditional spraying process relies on manual operation, and there are problems such as low efficiency, unstable coating quality, and high labor intensity. It has gradually failed to meet the needs of the modern aviation manufacturing industry. Therefore, an automatic spraying device for small aircraft parts is proposed.

[0003] Compared with the existing technology: the existing spraying equipment cannot automatically adjust the spraying angle according to the structure of the parts, so it is necessary to move the spraying equipment multiple times or adjust the part posture to achieve the desired spraying effect. This will increase the operation time. In addition, there are many small parts and the structure is complex. If the spraying machine cannot automatically adjust the angle to adapt to the spraying of different types of parts, it will cause uneven coating thickness. This will not only affect the appearance of the product, but also affect the subsequent aircraft assembly and product performance. Summary of the invention
