Problems solved by technology
However, in the existing automatic coin detection device, the coin will have mechanical damage or other defects during the transmission or flipping process, while the precious metal refined coin has a clear commemorative theme and exquisite design, and is mainly used for collection, and the visible surface damage will be reduced. its commercial value
[0003] At the same time, for the surface quality inspection of precious metal refined coins, the detection requirements and level are higher, and no device for the detection of refined coins has been seen so far.

The invention relates to a surface quality detection system for coin products. The surface quality detection system comprises an annular track conveying part, and a feeding queue conveying part, a front and back visual detection part I, a cam turning plate turning part, a front and back visual detection part II and a discharging sorting conveying part which are sequentially arranged on the annular track conveying part. The cam turning plate turning part comprises a cam plate, a driven bearing and a turning mechanism, the outer ring of the driven bearing can be matched with the convex curved surface of the cam plate, and the driven bearing is installed on the turning plate of the turning mechanism and can drive the turning plate of the turning mechanism to rotate. The turning mechanism is arranged on a carrying trolley of the annular track conveying component. The detection system adopts a lossless transmission and turn mode to continuously image the front side and the back side of a coin, and detects the side pattern quality, the front pattern quality, the hierarchical texture pattern, the invisible miniature pattern and other parameters of coin products.
Description
technical field [0001] The invention belongs to the technical field of testing equipment, and in particular relates to a coin product surface quality testing system. Background technique [0002] It is understood that the existing coin automatic detection device generally adopts the method of detecting the front and back separately, which has low working efficiency and large size of the outer corridor, and often needs to be equipped with a complex structure turning mechanism, which is prone to failure. Aiming at the above problems, the patent CN101339144B provides a double-sided automatic detection device for coins, which uses parallel light sources and front and back reflectors to image the coins passing through the imaging slits, which are captured by the line array camera and transported to the image processing system. Realize simultaneous automatic detection of both sides of the coin. However, in the existing automatic coin detection device, the coin will have mechani...
