Description

Technical Field

[0001] The utility model relates to the technical field of automobile detection, and more specifically to a visual error-proofing device. Background Art

[0002] When a car is driving, the stones and other debris thrown up by the inertia of the wheels will directly hit the paint layer of the car's wheel cover. The impact of the high-speed rotating stones will cause the car's paint layer to break and rust. At the same time, the noise caused by the stones hitting the sheet metal surface is loud, affecting the driving comfort. Anti-stone coating: A layer of coating sprayed on the surface of the car's wheel cover to prevent the stones and other debris thrown up by the wheels during the driving process from directly hitting the paint layer of the car's sheet metal, causing it to break and rust. The coating can also play a role in noise reduction.

[0003] With the rapid development of the automotive coating industry, the solution of spraying anti-stone chip coating on the sheet metal layer of automobile wheel covers to solve rust and high noise has gradually been applied in major automobile production lines. However, it currently mainly relies on manual spraying, and the risk of missed spraying is high. Usually, manual inspection is relied on to prevent missed spraying of anti-stone chip coating. The process requires that the employees at the anti-stone chip coating spraying station use a black whiteboard pen to draw inspections after completing the relevant spraying operations, and the employees of the next process do a secondary visual inspection, but manual visual inspections still have the problem of missed inspections. For this reason, it is necessary to design a device that uses a visual recognition industrial camera to inspect wheel hub coatings to solve the above shortcomings and problems in existing production.
