Description

Technical Field

[0001] The present invention relates to the technical field of drone shell production, and in particular to a drone shell spraying device with a protective function. Background Art

[0002] Drones are short for unmanned aircraft. In a broad sense, they are all types of remote-controlled aircraft that do not require a pilot to operate them. Drones are widely used and have been developed into various civilian fields. They can carry cameras, sprayers and other equipment to perform remote work in daily life, and can complete tasks without danger to personnel. In the process of drone production, manufacturing and maintenance, the spraying operation of the drone shell is crucial. High-quality spraying not only gives the drone a beautiful appearance, but also provides it with a protective coating, enhancing the durability and reliability of the drone in complex environments.

[0003] During the operation of traditional spraying devices, the nozzles are very prone to clogging. Since the paint used for spraying drone shells usually contains multiple ingredients, such as pigment particles, resins, etc., these ingredients are easy to precipitate and aggregate during long-term use or storage. In addition, after the solvent in the paint evaporates, the remaining ingredients may dry out, further exacerbating the risk of nozzle clogging. Nozzle clogging seriously affects the uniformity and accuracy of spraying, resulting in uneven thickness of the drone shell coating and spray leakage. This not only reduces the protective performance of the shell coating, such as reducing the drone's ability to resist wind and rain erosion and ultraviolet radiation, and shortening its service life, but also during the spraying process, nozzle clogging may cause pressure instability, causing paint to splash, posing a threat to the personal safety of the operator, and during the spraying operation, a large amount of harmful gases containing volatile organic compounds, dust particles and paint droplets will be generated. Once people inhale this harmful gas, it will cause damage to the body. Summary of the Invention
