Description

Technical Field

[0001] The utility model belongs to the field of wheel hub manufacturing, and particularly relates to a wheel hub identification and positioning mechanism with a color-variable background light source correction function. Background Art

[0002] During the processing and transportation of aluminum alloy wheels, it is often necessary to identify the wheel model, appearance, size, paint effect, etc. However, the camera is often unable to accurately capture the outline of the wheel spokes due to the influence of light when identifying. The current fill-in light technology is mostly fixed monochromatic light source. This correction method cannot adapt to the interference of external sunlight, and secondly, it cannot adapt to the background requirements of different color wheels. In addition, the processing environment of the wheel is relatively harsh. Fixed light source for a long time will leave a lot of dust and aluminum chips on the light source, resulting in poor fill-in light effect. Summary of the invention

[0003] In view of the above technical problems, the purpose of the utility model is to provide a wheel hub identification and positioning mechanism with a color-variable background light source correction function to improve the image effect of wheel hub photography.

After the wheel hub is clamped by the centering mechanism, the telescopic cylinder drives the color-variable light source to extend to the bottom of the wheel hub. The camera takes a first shot to identify the wheel hub model. The color-variable light source releases light of matching color and brightness according to the identified wheel hub model. The camera takes a picture of the wheel hub again to detect the shape and appearance of the wheel hub. After the detection, the color-variable light source retracts to the bottom of the centering mechanism, and the debris scraper cleans up the debris on the light source.
