Intelligent flexible manufacturing system and method for automobile bodies

Abstract

The invention discloses an intelligent flexible manufacturing system and a method for automobile bodies. The manufacturing method comprises the steps of searching the information of product parts and process data in a product data management system by means of a production resource central control system; generating operation instructions for each of all intelligent equipment, and respectively outputting the operation instructions to each of all manufacturing resources through the internet of things; and starting corresponding programs to finish the machining process by each manufacturing resource after the manufacturing resources receive corresponding operation instructions according to manufacturing resource codes. The manufacturing system comprises a product data management system, an internet of things system, an intelligent container, a modular intelligent tool and an industrial robot. According to the technical scheme of the invention, the intelligentization of a container tool is realized. Based on the distributed data management and the central control of the internet of things system, the rapid switching among welding robot programs is realized. Therefore, the mixed production of automobile parts of different configuration modes and different types can be realized, so that the production efficiency is improved. The error rate is lowered. Moreover, the number of special welding robots is reduced and the field utilization efficiency is improved. Furthermore, the manufacturing cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic control, and in particular relates to an intelligent flexible manufacturing system and method for an automobile body. Background technique [0002] At present, the automobile body manufacturing system mainly includes three production lines of stamping, welding and painting, among which the welding production line is an important part of the automobile body manufacturing system. [0003] At present, the traditional tools and fixtures used in the welding production lines of most automobile manufacturing enterprises basically do not have the functions of part identification and adjustment, and are only suitable for the large-volume single-model production mode, not suitable for the emerging mass-customized production mode. When the production plan becomes more and more diversified, it often includes mixed production of multiple similar models. If traditional containers and fixtures are used, it is ...
