Material identifier tracking method

Abstract

The invention provides a material identifier tracking method. The material identifier tracking method comprises the steps that during the period that materials are located in a first processing device, material identifier information is separated from the materials and temporarily stored in an identifier card of the first processing device; a material carrying device carries away the materials from the first processing device, and an identifier information reading / writing device on the material carrying device transfers the material identifier information in the identifier card of the first processing device into an identifier card on the material carrying device by cutting; the material carrying device is moved to a second processing device, and the identifier information reading / writing device on the material carrying device judges whether material identifier information of an identifier card of the second processing device is null or not; and if the material identifier information of the identifier card of the second processing device is null, the material carrying device carries the materials into the second processing device, and the identifier information reading / writing device on the material carrying device transfers the material identifier information of the identifier card on the material carrying device into the identifier card of the second processing device by cutting. Compared with the prior art, the method can realize automatic tracking of a material identifier in a whole process.

Description

【Technical field】 [0001] The invention relates to the technical field of material identification tracking, in particular to a material identification tracking method. 【Background technique】 [0002] In modern industrial manufacturing, the identification card of a material is the carrier of some important information in the manufacturing process of the material, and plays a vital role in the identification of the material in the manufacturing process. Traditional manual identification cards are not suitable for modern manufacturing because they are inconvenient for storage and cannot be automatically recognized by machines or have low identification efficiency. At present, common identification management includes barcode identification, two-dimensional code identification and RFID (Radio Frequency Identification, radio frequency identification) identification , can realize efficient identification and automatic identification of materials. [0003] However, for special indu...

Problems solved by technology

Traditional manual identification cards are not suitable for modern manufacturing because they are inconvenient for storage and cannot be automatically recognized by machines or have low identification efficiency. At present, common identification management includes barcode identification, two-dimensional code identification and RFID (Radio Frequency Identification, radio frequency identification) identification , can realize efficient identification and automatic identification of materials

[0003] However, for special industries such as the heat treatment industry, due to the presence of harsh environments such as high temperature, oil, hot water, acid-base, and chemical media, ordinary barcodes and two-dimensional codes cannot be put into the furnace, oil, or water with materials at all, even if they are resistant Oil, water, acid and alkali resistant RFID tags cannot adapt to the high temperature of 900 degrees in the furnace

Therefore, the current conventional practice in the heat treatment industry is to manually track identification cards (manual, barcode, two-dimensional code, RFID). Material movement, and then workers move the label again, which often leads to confusion of goods due to forgetting to move the label in time, and there is no way to realize automatic management
