Surface quality on-line detection system for coin finished goods

Abstract

The invention discloses an online detection system for the surface quality of a coin finished product, which comprises a group of 'O'-shaped conveyer belt which is formed by two driving wheels, and a group of 'C'-shaped conveyer belt which is formed by driving wheels, wherein the 'C'-shaped conveyer belt is winded on one end of the 'O'-shaped conveyer belt to form a turnover mechanism. The online detection system for the surface quality of the coin finished product is characterized in that one end of the 'O'-shaped conveyer belt is provided with a centrifugal turntable; bright field detectors and dark field detectors are arranged on linear conveying sections of two conveyer belts respectively; a slideway is arranged between the centrifugal turntable and the 'O'-shaped conveyer belt for connection; lower parts of the two conveyer belts are provided with defect ware collecting boxes; and one side of the turnover mechanism is provided with a programmable controller. The online detection system for the surface quality of the coin finished product adopts bright and dark composite fields to automatically detect the quality of the coin finished product, is easy to catch the characteristics and the defects of the coin, effectively reduces the rejection rate, has the continuous waste automatic alarm and stop function which is linked with an embossing press, performs real-time automatic detection and control on the quality of online products, and greatly improves the detection accuracy and the labor productivity.

Description

technical field [0001] The invention relates to the technical field of coin manufacturing, in particular to an online detection system for the surface quality of finished coin products. Background technique [0002] At present, in the coinage industry, only the quality of the flat cake of the coin is automatically detected, and the quality of the finished coin is mainly completed by manual inspection. Now there is also a bright field coaxial light source to automatically detect the surface quality of the finished coin, but This single bright field detection device cannot realize real-time control of continuous waste products in production, and it cannot accurately capture some characteristic defects of coins, which has certain limitations, and the rate of missed waste and false waste is relatively high. Contents of the invention [0003] The purpose of the present invention is to provide a coin surface quality on-line detection device for the deficiencies in the prior art....
