[0002] At present, people's living standards are getting higher and higher. In the process of daily travel, people also have more diverse choices. When traveling long distances, people generally choose public transportation. When traveling short distances, the most commonly used means of travel is motor vehicles. Among the many parts of a motor vehicle, the engine is its most important part, providing power for it. Among them, the valve is an important internal structure, and the engine valve must be processed to a certain accuracy during the production process to prevent air leakage when the valve is used. Therefore, the valve needs to undergo a series of tests after processing.

During the visual inspection, the valves need to be transported through a conveying device and fixed to rotate 360° to ensure comprehensive inspection. However, most of the current devices have relatively discontinuous fixed rotation movements after transportation, which is inefficient in mass production and greatly delays production progress.
