Cast pipe quality management method, cast pipe produced by using above method, and two-dimensional barcode tag

Abstract

The invention discloses a cast pipe quality management method, a cast pipe and a two-dimensional barcode tag. The method comprises steps: (1) production source information of each cast pipe during the production process is inputted to a two-dimensional barcode management system, and a cast pipe record corresponding to each pipe batch number is generated in the two-dimensional barcode management system; (2) after the cast pipe quality is tested to be qualified, a two-dimensional barcode tag is printed, and the two-dimensional barcode tag is stuck on the corresponding cast pipe which is tested to be qualified; (3) shipping information of the cast pipe which is tested to be qualified is stored to the cast pipe record; and (4) the two-dimensional barcode tag is scanned, if a corresponding cast pipe record is found, the two-dimensional barcode management system displays information of the cast pipe record, and if not, the two-dimensional barcode management system displays false information. The method solves the problems that repeated and wrong numbers appear during the pipe number transmission process and the efficiency is low, and has the advantages that mistakes can be avoided during the cast pipe number transmission process, quality tracing can be realized, and fakeness can be prevented.

Description

technical field [0001] The invention relates to a casting pipe, a quality management method in the production process of the casting pipe and a two-dimensional code label used for the casting pipe. Background technique [0002] For a long time, the pipe numbers of ductile iron pipes have been sprayed on the outer wall, and the spraying adopts the method of template engraving, that is, artificially engraving the commonly used and unchanged alphanumeric sequences on the metal mother board, such as the implementation of the standard number, enterprise logo And the name of the unit, and for the frequently changing batch number and pipe number, by selecting the corresponding number on another metal mother board, the method of spraying is selected bit by bit, so as to realize the spraying of different pipe numbers for different cast pipes. This traditional spraying method of ductile iron pipe numbers has the advantages of simple operation and is widely used in cast pipe manufactur...

AI Technical Summary

Problems solved by technology

However, the pipe number sprayed by this method cannot be automatically recognized by the computer, and the number must be manually copied and transferred manually, so it is inevitable that there will be repeated and wrong numbers in the transfer process of the pipe number, and the efficiency is low
