基于单件标识的锻造铝合金车轮质量追溯技术

Quality traceability technology of forged aluminum alloy wheels based on single piece identification

为满足锻造铝合金车轮企业对产品质量信息的可追溯性要求,提出了一套基于激光刻码的单件标识的全流程质量追溯技术。在介绍激光刻码原理的基础上,通过单件标识识别率的高低来校对不同生产单元的最佳刻码位置。在生产单元内,使用逻辑堆栈的方式将虚拟码和生产过程的质量数据进行绑定;在生产单元外,利用实体码对接制造执行系统(MES),保证追溯信息的完整性和连贯性。结合锻造铝合金车轮产品和生产的特点,定义了可追溯性的范围和流程,提出建立以单件追溯为核心的追溯方法,实现对产品的全过程追溯管理。

In order to meet the traceability requirements of forged aluminum alloy wheel companies on product quality information,a set of full-process quality traceability technology based on laser-engraved single-piece identification was proposed,and on basis of introduction of laser engraving principle,the optimal engraving position of different production units was checked by the level of identification rate of single piece identification. Then,in the production unit,the virtual code was bound to the production process quality data by the logical stack,and outside the production unit,the MES manufacturing execution system was connected by the physical code to ensure the integrity and continuity of traceability information. Combined with the characteristics of forged aluminum alloy wheel and production,the scope and process of traceability were defined,and the establishment of a traceability method with single piece traceability as the core was proposed to realize the traceability management for the entire process of product.
