Coin finished product surface quality inspection system

Abstract

The invention discloses a coin finished product surface quality inspection system comprising a coin conveying channel, an image processing module and a main control module, wherein a coin conveying rotary table, a coin detection device, a coin kicking device and a discharging hopper are sequentially arranged on the coin conveying channel; a detection platform, a camera and a light source are arranged in the coin detection device; the detection platform comprises a coin sliding plate and a reflecting mirror; an image collecting seam is arranged on the coin sliding plate; the light source is parallel to the plane of the coin sliding plate and projected to the reflecting mirror; images of the upper face and the lower face of a coin are reflected to the camera by the reflecting mirror; image information obtained by the camera is transmitted to the image processing module for processing to distinguish whether the surface quality of the coin is qualified; a distinguished result is sent to the main control module by the image processing module; and coin kicking action of the coin kicking device is controlled by the main control module according to the received distinguished result. The coin finished product surface quality inspection system has relatively high degree of automation. By utilizing the coin finished product surface quality inspection system, the upper surface and the lower surface of the coin can be detected simultaneously, the work is reliable, and negative social impact caused by factory unaccepted products can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of quality detection in the coin production process, in particular to a finished coin surface quality inspection system that can be applied to mints or banks and can check the graphics, text and shape of the finished coin surface. Background technique [0002] With the continuous development of coin production technology, the degree of automation and efficiency of finished coin manufacturing, printing and packaging processes are also constantly improving. At the same time, the quality control of coin products is becoming increasingly strict, and the printing industry has also formulated regulations for unqualified coins. Strict criteria for judging. [0003] However, waste and unqualified products will inevitably be produced in the coin production process. For a long time before, the factory inspection of coins was carried out manually. The situation of large investment, high labor intensity and unstable ins...

Problems solved by technology

However, the existing equipment usually discharges the material directly into the hopper and then transports it manually. It also requires quality inspection personnel to conduct a second confirmation of the products placed on the logistics line. The process and equipment are relatively cumbersome.
