Automatic coin quality detection device

Abstract

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.

Description

technical field [0001] The invention relates to a coin production product quality detection device, in particular to a high-precision multifunctional coin production quality automatic detection device based on a vision system realized by applying image processing technology. Background technique [0002] At present, there are mainly three kinds of coins in circulation in my country: one yuan coin, five cents coin and one dime coin. In addition, there are a certain number of commemorative coins. Due to the large population and the large number of coins in circulation in China, an automated coinage process is the only way to improve production efficiency. With the improvement of national power, people have higher and higher requirements for the quality of currency that represents the image of the country. Using the quality inspection system of finished coin products (referred to as flower cakes) to replace the traditional manual quality inspection can realize the automatic c...
