Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a product safety supervision technology, in particular to a product identification, tracking and management method based on two-dimensional codes.
[ background of the invention ]
At present, various suppliers, manufacturers, distributors and distributors need to check and verify various documents and certificates of products, most documents are manually recorded and input into a local database, or are partially generated by LIMS software or production software, and are integrated to generate partial information, especially for batch production and inspection records, and the manual input and record integration with different frequencies can involve human errors, so that the system is inefficient and time-consuming; moreover, tracking the history of a particular product is time consuming and potentially erroneous due to manual operations.
As a new information storage, transmission and identification technology, the research of two-dimensional code technology started in the 80 th 20 th century and has been widely applied abroad. The research of the two-dimension code in China starts in 1993 and is currently applied to industries such as warehouse logistics, certificates of government departments and the like. The two-dimension code tracing is a verification and query process of information such as production date of a product, various performances of the product, production batch numbers, production personnel and the like by scanning the traceable two-dimension code on the product package by a consumer when an enterprise purchases parts with the traceable code. At present, data detected by most factory automation lines are not stored or do not have two-dimensional codes, and detailed data of products, including production time, detection data, personnel information and the like, cannot be inquired from the two-dimensional codes.
In particular to automatic production and processing of automobile motor parts, which belongs to typical discontinuous, long-flow and cross-station discrete manufacturing, the production process is complex in process, the specifications of production materials are various, and the states of products in production can change along with the change of time and the progress of production and flow between different workshops and stations. However, the information collection of the products in process still continues to use the traditional manual reporting and counting mode, the dynamic change of the products in process cannot be reflected, the timely feedback of the information of the products in process is delayed, the synchronization of the information flow and the logistics of the products in process in a workshop cannot be realized, the production efficiency of the workshop is seriously influenced, and the production process cost is increased. Meanwhile, when problems occur, specific links and specific responsible persons cannot be traced, and difficulty is increased for quality control and production tracing. Therefore, the traditional automobile motor part manufacturing industry has extensive product management and low automation level, and cannot meet the requirements of complexity of a production process, randomness of order requirements, flexibility of market response and the like. Bar code technology is widely applied in the industrial field at present, and a factory collects bar code information attached to products and parts through a bar code scanning gun and other devices, so that a more detailed data source is provided for enterprise information flow. However, the bar code has the problems of easy fouling, no high temperature resistance and the like, and meanwhile, blanks and parts used in the manufacturing process of heavy equipment are mostly large steel members, so that the surfaces are rough and easy to rust, common bar code labels are difficult to adhere firmly, and the bar code is easy to fall off during lifting and carrying.
