Assembly line product information collection method and collection device

Abstract

The invention discloses an assembly line product information collection device which includes a data collection system, a data transmission system, a data processing system and an information feedback system. The data collection system collects the identity information of an assembly line product. The data transmission system exchanges data with the work stations on the assembly line, and the work stations on the assembly line collect field data. The data processing system acquires the field data collected by the work stations on the assembly line through the data transmission system, and processes the field data to generate result data, wherein the result data includes a quality control chart established and optimized based on the field data. The information feedback system feeds back the result data generated by the data processing system to a remote terminal. The invention further discloses an assembly line product information collection method. Through the assembly line product information collection device and the collection method of the invention, the efficiency of information collection can be improved, convenient input, statistics and feedback can be realized, the first-pass yield of goods receipt is improved, and the rework rate and the process cost are reduced.

Description

technical field [0001] The invention relates to the field of automobile manufacturing lines, and more specifically, to an information collection method and a collection device for assembly line products. Background technique [0002] Under the national strategic plan of "Made in China 2025", a new wave of manufacturing revolution is sweeping. To realize Industry 4.0, we must first solve the problem of production automation. The automation of production is a prerequisite for realizing intelligent manufacturing and an important basis for realizing intelligent products and refined management. Realizing production automation requires not only the use of smart devices, but also the need to solve the problem of information islands and realize interconnection in production, and timely interoperability of data is an important part of it. [0003] As far as the field of automobile manufacturing is concerned, the quality requirement of "paint free pass" (painting zero defect) has ap...

AI Technical Summary

Problems solved by technology

There are thousands of quality information tables every day, the amount of data is large, the manual statistics take a long time, the efficiency is low, and there are situations where the description is not standardized and the statistics are not in place

[0006] 2) Information feedback is inefficient and lagging behind

At present, the paint inspection card information on the submission line is stored on paper and stored in a decentralized manner, which is only used for traceability, without in-depth data mining of historical data, so preventive work cannot be carried out

[0008] Therefore, under the existing quality management system, defect problems are exposed relatively late, and the number of defects is relatively large, which not only affects the quality control work of the spray shop, but also increases rework costs, and the potential reduction in production efficiency will also bring losses
