The invention relates to an automatic
coin quality detection device, in particular to a high-precision multifunctional automatic
coin production quality detection device based on a
visual system, realized by applying an
image processing technology. The detection device comprises a combined illumination imaging
light source, an image receiving unit, an
image processing unit, a result output unit and a damaged
coin discarding device, wherein the image receiving unit, the
image processing unit, the result output unit and the damaged coin discarding device are sequentially connected; the combined illumination imaging
light source adopts a mode that surface light sources at a
high angle and a low angle illuminate at the same time; the image receiving unit collects image data on the coin surface; the image
processing unit process the collected image data, confirms and discards defective products according to a production standard and transfers real-time detected images and analysis result information to the result output unit; and the damaged coin discarding device discards the ultra-detective products according to the control information of the image
processing unit. The invention has the objective detection standard, can quantitatively prescribe, improves the production efficiency, can continuously
upgrade the detection speed, emancipates the labor force and improves the
automation degree of coinage.
