Assembly line vehicle inspection control method and device

Abstract

The embodiment of the invention provides an assembly line vehicle inspection control method and device. Through acquiring vehicle type information and vehicle type derived information of a to-be-inspected vehicle, main inspection working information and derived inspection working information are determined; according to the main inspection working information and the derived inspection working information, inspection guidance information is generated; and finally, through an information display board in an inspection working position, the inspection guidance information is displayed. As for each inspection working position, the inspection guidance information can be displayed in real time, depending on artificial memory of an inspector is not needed, the phenomenon that working hours are wasted as the vehicle type derived information is determined to further result in position missing and leaving can be avoided, and working guidance is provided for the inspector so as to realize standardized production.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to an assembly line vehicle inspection control method and device. Background technique [0002] With the rapid growth of domestic automobile consumption in recent years, the output of automobiles has exceeded 8.88 million units, and the annual production and sales volume has hit a record high, breaking the global record many times, ranking first in the world for several consecutive years; after several years of rapid and crazy growth, the automobile industry The growth rate has shown a downward trend, and the competition among OEMs is also undergoing tremendous changes. The original price competition has gradually transformed into competition for product quality. Good vehicle quality has gradually become an important factor for customers to choose In the future, the quality assurance capability of OEMs will become the core competitiveness of OEMs. [0003] In order to...

AI Technical Summary

Problems solved by technology

[0003] In order to ensure the quality of the vehicle, after the vehicle is assembled, the OEM will conduct a comprehensive verification and inspection of the vehicle quality. The inspection items are generally divided into dynamic inspection and static inspection. Dynamic inspection generally refers to functional equipment inspection, rain seal inspection, runway inspection, etc. Walking inspection; static inspection generally includes inspections of car body appearance, coating, vehicle interior and exterior decoration, etc., mainly for items that affect the customer's senses, with 2,854 inspection items and many and detailed inspection criteria; at the same time, according to the configuration of the vehicle Different, there will be many kinds of derivations, and the dynamic inspection between different derivations is not much different, while the static inspection generally has different points of change in the inspection items and benchmarks of each derivation. In order to save costs, most OEMs adopt uniform For mixed-line production, this sets up a lot of difficulties for static checking

[0004] In order to ensure the efficiency and quality of loading, when carrying out static inspection of vehicles, it is stipulated that if there are five pieces of the same defect, it is defined as multiple occurrences, and key correspondence is required; static inspection generally places the vehicle statically on the conveyor chain, and the inspection items are determined by a certain number. The beats are evenly distributed to each post. In order to achieve standardized production, the start line and end line of the post are set. However, there are often on-site staff turnover due to issues such as confirming the derivation before the inspection and confirming the inspection benchmark. If an emergency occurs, it cannot be realized in time. Stop calling and waiting, and at the same time, the team leader cannot effectively monitor the problems that exist during the inspection by the inspector

[0005] The multi-derivation quality inspection of the current hybrid assembly line has no relevant system guarantee, and it all depends on the quality benchmark memory during the inspector training. When the model derivation is frequently switched, the inspection items are not clearly recorded, resulting in missed inspections and wrong inspections; for multiple problems, There is no effective system for automatic management on site, and timely communication of quality information cannot be realized; at the same time, due to the rhythm requirements of standardized assembly line operations, man-hours are often lost due to confirmation of derived information during previous inspections, and it is impossible to realize standardized production.
