Quality traceability system for bag-folding process of automobile safety air bag production line

Abstract

The invention discloses a quality traceability system for a bag-folding process of an automobile safety air bag production line. The system comprises an information collection device, a PLC (programmable logic controller) system and a computer processing system, wherein the information collection device acquires various parameters of each station in the bag-folding process of the air bag production line in real time and transmits information to the computer processing system; a fault diagnosis system based on multi-sensor information fusion performs fault diagnosis and early warning on data; the acquired data and fault information are stored in an SQL Server 2005 database; algorithms in a software design are written by a Java language; a front interface adopts a dynamic web page manner which is realized by HTML (hypertext markup language), DIV (data in voice), CSS (computer system simulation) and Jsp (java server pages) codes; and the fault statistic result is displayed in a graphic manner, and simultaneously, information statistics and inquiry of the bag-folding process in the web page manner provides a more convenient browsing mode. The traceability system adopts bar coding information as the unique identification of a product, so that the historical data tracing function of the product in the bag-folding process is achieved, and the dynamic adjustment of the whole air bag folding process is achieved.

Description

technical field [0001] The invention relates to a quality traceability system for the bag folding process of an automobile safety airbag production line. Background technique [0002] As an important safety component of a car, the quality of the airbag is directly related to the personal safety of the passengers. Poor assembly of airbags, such as assembly of components that do not meet the design requirements, or even wrong or missing assembly on the production line may easily cause accidental injury. In addition, in litigation disputes involving airbags, it is impossible to determine whether the responsible party belongs to the airbag manufacturer or the automobile manufacturer. In this regard, in addition to strictly and accurately monitoring the production process of each airbag, especially the equipment working status and fault information of key stations on the production line, another important measure is to keep detailed product data records. Once a certain airbag h...
