Description

Technical Field

[0001] The invention relates to the technical field of component detection, and in particular to a steering wheel visual detection device. Background Art

[0002] In the field of automotive parts manufacturing, the steering wheel is a key component that connects the driver to the vehicle control system, and its quality and safety are of vital importance. Traditionally, the quality inspection of steering wheels mainly relies on manual visual inspection, that is, the quality inspectors observe the surface condition of the steering wheel with the naked eye to determine whether there are scratches, uneven color, deformation or size deviation. However, this inspection method has many limitations.

[0003] First, manual visual inspection is easily affected by subjective factors. Different quality inspectors may have different judgments on the quality of the same steering wheel due to differences in experience, vision or concentration, resulting in inconsistent testing standards. Second, manual inspection is difficult to ensure comprehensiveness and accuracy. In particular, it is often difficult for manual inspection to accurately identify tiny scratches, color gradients or slight size deviations on the steering wheel. If these defects are not discovered and repaired in time, they may affect the driving experience during use and even endanger driving safety.

[0004] With the advancement of science and technology, visual inspection plays an increasingly important role in industry. With the rapid development of the automotive manufacturing industry and the continuous improvement of the automation level of production lines, manual visual inspection can no longer meet the needs of efficient production. On the one hand, manual inspection is slow and difficult to keep up with the fast production pace, resulting in low inspection efficiency. On the other hand, long-term manual inspection can easily cause fatigue to quality inspectors, further reducing the accuracy of inspection. Therefore, how to use visual inspection to detect steering wheels has become an urgent problem to be solved. Summary of the invention
