The actuality of bar code technology

In order to reduce the complexity of the tool management staff and improve the work efficiency of all the tools of the enterprise, in accordance with the defined tool coding rules, according to the different tool types and storage positions, the production is in accordance with the actual production of the enterprise. The required tool bar codebook. Due to the wide variety of tools, according to the purpose and specifications, each warehouse has more than 5000 types, the total number is up to tens of thousands. How to achieve fast and accurate tool information has become a difficult point in the whole project.

In order to solve the problem of identifying the bar code of the tool, the project team has proposed a variety of solutions. Finally, according to the actual situation of the enterprise, it is unanimously approved to record the bar code of the bar by means of bar code. The barcode book is designed as a 30-page booklet according to the size of page A4, and each page can be inserted with 20 bar code labels, which are marked with the tool name, specification and barcode printed by the barcode printer. According to the actual production needs, according to the type of tool, each barn is made into a bar code book, and various bar code codes are classified into books to realize the bar code scanning requirements. The tool coding rules combined with the implementation and application of bar code scanning can be matched with the bar code recognition system. After the bar code scanner scans the tool identification, the tool management system can recognize it and automatically locate the tool to display the relevant information of the tool. Barcode scanning replaces the original manual record borrowing/return management method. Summary Due to the particularity of aerospace manufacturing enterprises, some advanced and mature identification technologies are temporarily not applicable to actual production. For example, wireless identification RFID based on radio frequency technology has been promoted and applied in many industries. At present, the use of bar code technology is a good choice for aerospace manufacturing enterprises with single-piece and small-volume production, which can meet the management requirements of standardized, systematic and informational tools, and improve the level of production automation. It has laid a good technical foundation for the establishment of aerospace model digital production line. With the continuous development of information technology, the way of tool identification will have rapid changes and progress, and will certainly play a positive role in the scientific and technological progress in the field of aerospace engineering.
