However, many coins have been circulated for a long time, and have long service life, and in the process of use, the surface of the coins is damaged due to many factors, especially, the coins with soft parts are damaged due to the fact that the surfaces of the coins are damaged even due to artificial damage or other unresistible factors, and deep scratches or pits are formed, so that the damaged coins are required to be separately collected and processed when the bank can exchange values for the coins, and therefore, the damaged coins are required to be identified and separately processed when the banknote counter (coin sorter) is used for counting the coins.
In order to reduce the labor intensity of staff, a visual recognition system is required to be arranged on a conveying channel of the coins so as to be convenient for carrying out image recognition on the surfaces of the coins, so that damaged coins can be rapidly recognized, but as the orientations of the front and the back sides of the coins in the conveying process can not be determined, in the prior art, in order to simultaneously detect the front and the back sides of the coins, a double-sided detection structure is required to be arranged on the conveying channel, namely, a group of obliquely arranged reflector structures are arranged on the upper side and the lower side of the channel, and a visual recognition camera and a light source are arranged at the positions of the side surfaces of the conveying channel opposite to the reflectors, wherein the upper reflector structure is directly aligned to the upper surface of the coins in the conveying channel, and in order to facilitate the lower reflector to reflect the lower surface of the coins, a detection slit is required to be arranged on the position of the conveying channel corresponding to the reflector, the lower reflector reflects the light of the lower surface of the coins, the images reflected by the two groups of reflectors are simultaneously recognized by the visual recognition camera,

It should be noted that, the CCD camera 24 is a conventional visual recognition camera and is equipped with a visual recognition system, the two sides of the coin passing through the detection station are simultaneously subjected to image acquisition by the reflection of the two sets of reflecting mirrors 22, and whether the surface of the coin is damaged is recognized, and meanwhile, the denomination of the coin passing through the detection station is recorded by image recognition, so as to record the total amount, and realize the banknote counting operation of the coin, while the conventional technology related to the image recognition technology is widely applied, therefore, the embodiment is not repeated, in the actual detection, the coin is driven to slide downwards from the conveying channel 1 and pass through the transparent plate 23, the hard raised strips 25 support the coin to slide in the detection station, the reflecting mirror 22 below reflects the image of the lower surface of the coin through the transparent plate 23, the reflecting the image of the upper surface of the coin above reflecting mirror 22 is simultaneously reflected into the CCD camera 24 for image recognition, and further realizing the simultaneous coin recognition, wherein, the transparent plate 23 is arranged to replace the conventional detection gap, so that the detection area of the lower surface of the coin is increased, the detection effect is improved, the transparent plate 23 is provided with the hard raised strips 25, the transparent plate 23 is used for supporting the coin, the detection efficiency is greatly reduced, the contact with the transparent plate 23 is greatly, and the damage on the subsequent detection result is avoided, and the transparent plate 23 is greatly influenced.
In the above embodiment, although the hard protruding strips 25 can expose most of the area of the bottom of the coin when the hard protruding strips 25 support the coin to slide, the hard protruding strips 25 can not be blocked and do not affect detection for some large scratches and pits, but it is difficult to detect and identify if the hard protruding strips 25 are blocked for some small damages, so in order to solve the above problem, the present embodiment further provides the following technical scheme, referring to fig. 2 of the specification, the conveying channel 1 is further provided with the rotating and conveying assembly 7, the rotating and conveying assembly 7 is located at the detection station of the conveying channel 1, and the rotating and conveying assembly 7 is used for driving the coin to rotate when the coin passes through the detection station, thereby avoiding the hard protruding strips 25 to fix the blocking area of the coin, ensuring that the lower surface of the coin can be completely reflected by the reflecting mirror 22 when the coin passes through the detection area, and improving the detection effect.

It should be noted that, when the coin passes through the detection section, the circumferential surface of the coin contacts with the driving sections of the two groups of elastic belts 711, so that the coin rotates under the movement of the two groups of elastic belts 711, and meanwhile, the downward movement of the group of elastic belts 711 has a larger movement speed, so that the coin still has a downward movement trend while rotating, and the coin can be ensured to smoothly pass through the detection station, thereby ensuring the full collection of the surface information of the coin.
In the above technical solution, if the size of the coin detected by the device is fixed, the driving of the coin will not be affected by the position fixing of the two sets of elastic belts 711, but when the coin detected by the device has more than two diameters and the diameter difference is not large, the adaptability of the two sets of belt type rotating and conveying assemblies 71 which are fixedly arranged is poor, for this purpose, the present embodiment further provides the following technical solution: specifically, the elastic belt 711 is of an elastic structure, for example, the elastic belt 711 is made of elastic rubber, the supporting wheels 712 of the two belt-type rotary conveying assemblies 71 are arranged in a staggered manner, and a buffer space is reserved between the inner area of the conveying channel 1 and the side wall of the conveying channel 1 by the elastic belt 711.
By adopting the above technical scheme, when relatively large coins start to slide into the two groups of belt-type rotary conveying assemblies 71, the coins can firstly contact the supporting wheel 712 at the highest point due to dislocation of the supporting wheels 712 and then move downwards to the supporting wheel 712 at the second high point position at the other side, at this time, the coins can reversely extrude the opposite elastic belt 711 under the extrusion of the supporting wheel 712, so that the elastic belt 711 deforms, and meanwhile, the elastic belt 711 has elasticity, so that the coins can still contact with the edges of the coins, and the continuous driving of the coins is realized, so that the coins can smoothly pass through the two groups of supporting wheels 712 which are mutually opposite, the coins are prevented from being blocked, and the adaptability of the device is further improved.
Further, when the device faces more coins and the difference between coins is larger, the embodiment further provides a technical solution, specifically, referring to fig. 9 and 10 of the specification, a group of belt type rotating assembly 71 further includes a V-shaped frame 713, the V-shaped frame 713 is rotatably mounted in the mounting box 21, both ends of the V-shaped frame 713 extend to the inner side of the conveying channel 1 and contact with the driving section of the elastic belt 711 in the group of belt type rotating assembly 71, the V-shaped frame 713 rotates along the conveying plane of the conveying channel 1, before the coins do not enter between the two groups of belt type rotating assembly 71, the V-shaped frame 713 is in an intermediate state under the elastic action of the elastic belt 711 itself, the intermediate state refers to a state of the V-shaped frame 713 when the connecting line direction of both ends of the V-shaped frame 713 is parallel to the conveying direction of the conveying channel 1, and when the V-shaped frame 713 is in the intermediate state, the distance value between the connecting line of both ends of the auxiliary wheel 714 and the central line of the conveying channel 1 is greater than the distance value between the common tangent line of the two groups of supporting wheels 712 and the central line of the conveying channel 1 in the group of belt type rotating assembly 71, that is closer to the central line of the elastic belt type supporting part 711 than the central line of the belt type supporting part 711 in the group of the conveying channel 1.
