Metal cap double-sided code assignment machine and code assignment method thereof

Abstract

The invention belongs to the technical field of metal cap processing, and provides a metal cap double-sided code assignment machine and a code assignment method thereof. According to the metal cap double-sided code assignment machine, a central code library generates a matched two-dimensional code and a verification code, a bottom code assignment position completes bottom two-dimensional code and plate number code assignment, and a top code assignment position completes front verification code and plate number code assignment. Therefore, batch implementation of double-sided code assignment can be realized by only one time of processing, matching of the double-sided code values can be ensured and the code assignment cost and the code assignment risk can be reduced. Integrated management of the data code packet can be realized through combination of the metal cap double-sided code assignment machine and the central code library, and the security, the reliability and the integrity of the encrypted data code packet can be managed and verified so that secure decryption and code assignment of the data code packet and updating and supervision of the data code packet state can be realized, and thus the use security of the code packet can be ensured. The whole metal cap double-sided code assignment machine realizes code assignment under the no-stop state of the production line so that the technical threshold of metal cap double-sided code assignment can be reduced and the processing period can be shortened.

Description

technical field [0001] The invention belongs to the technical field of metal cap processing, and in particular relates to a metal cap double-sided coding machine and a coding method thereof. Background technique [0002] With the development and progress of society, the safety of food and medicine has attracted more and more attention from the society, consumers' awareness of rights protection has become stronger, and enterprises have paid more and more attention to the management of social circulation products. To this end, governments of various countries have introduced regulatory policies one after another, and established a product traceability regulatory system centered on electronic regulatory codes in key industries. At present, in the food and beverage industry, there have been a large number of two-dimensional code product packaging implementation methods of one object, one code, generally paper packaging and plastic product packaging. The technology of digital pr...
