Quality control device and method for banknote product

Abstract

The invention discloses a quality control device and method for a banknote product. According to the quality control method, two sets of online gravure secondary checking equipment, letterpress printing and large piece combining machine, one set of small piece RMB inspection rejecting equipment according to serial number for a waste picking machine and data collecting analysis and form forming equipment are at least comprised; a relatively-mature imprinting three-in-one online detection system is improved into the letterpress printing and large piece combining machine, so that quality full inspection of large-piece note surface after the banknote product is imprinted is realized by using a machine vision detection technology, data are transmitted to the small piece RMB inspection rejecting equipment according to the serial number for the waste picking machine and further automatic rejection of waste banknote products is realized. The quality control device and method disclosed by the invention have the advantages that due to the adoption of the device, a novel banknote production process with the advantages of concise flow, high efficiency, strong control force of quality risk and high automatic degree can be formed.

Description

technical field [0001] The invention relates to the fields of valuable securities printing, machine vision detection and database, in particular to a banknote product quality control device and control method. Background technique [0002] Due to the particularity of the quality control of banknote products, it is required to conduct a "full inspection" on each banknote product. At present, in the domestic banknote printing industry, there are mainly two types of "banknote printing verification process" and "separator full inspection process". The quality control method conducts a full inspection of the quality of banknote products. The former mainly relies on the large-sheet inspection machine to inspect banknote products in large sheets, and relies on ID codes and banknote product numbers as intermediate links to transfer waste information to manual rejecting; its process structure is complex, and the subsystems and processes involved There are many nodes and technical li...

Problems solved by technology

The former mainly relies on the large-sheet inspection machine to inspect banknote products in large sheets, and relies on ID codes and banknote product numbers as intermediate links to transfer waste information to manual rejecting; its process structure is complex, and the subsystems and processes involved There are many nodes and technical links, which increase the overall system risk of process operation

The latter relies on the sorting machine to check the banknote products with small openings, the production efficiency is low, and the price is expensive

[0003] The foreign Chiori company checks the product quality before printing the code, not the final quality inspection of the product in the strict sense. The Japanese Komori company does not have such a quality control method from the existing information. On the whole, At present, there is no equipment and related processes in the banknote printing industry at home and abroad that combine code printing and final quality inspection of large sheet products.
