Data acquisition system and method for automobile air conditioner assembly line

Abstract

The invention discloses a data acquisition system for an automobile air conditioner assembly line. The data acquisition system comprises a computer, electronic tags, read-write devices and a programmable logic controller. The electronic tags are arranged on assembled automobile air conditioner shells. The multiple read-write devices are arranged on all stations on the automobile air conditioner assembly line respectively, and are respectively provided with an antenna which is used for transmitting radio frequency signals to the corresponding electronic tag. The read-write devices are connected with the programmable logic controller through bus modules. The programmable logic controller is connected with the computer. The invention further discloses a data acquisition method for the automobile air conditioner assembly line. The data acquisition system and method are particularly suitable for the automobile air conditioner assembly line, all the process amount and detection result data generated when the automobile air conditioner shells are assembled at all the assembly stations on the automobile air conditioner assembly line can be effectively acquired and stored in time.

Description

technical field [0001] The invention relates to the technical field of data collection, in particular to a data collection system and collection method used on an assembly line of an automobile air conditioner. Background technique [0002] At present, due to the continuous improvement of the quality requirements of the module supporting factories by the OEMs, there are more and more requirements for error prevention and testing on the air-conditioning assembly line. At the same time, due to the continuous advancement of industrial technology, with the enrichment of detection methods and complete equipment functions, the relevant detection data obtained from the assembly line are also increasing. [0003] The detection on the assembly line of the automobile air conditioner is mainly divided into several points: 1. Anti-wrong installation, prevent missing or under-installed workpieces, mainly through photoelectric sensor detection, and mainly obtain digital information. 2. T...

Problems solved by technology

[0005] The above labeling method can ensure the quality of off-line products, but due to the large number of air-conditioning module parts, complex assembly process, incoming material problems, workshop management problems, etc.

When encountering customer complaints or analyzing product quality problems, there is a lack of intuitive data evidence, which brings certain difficulties to statistics and analysis of the reasons. The module supporting factory is also at a disadvantage due to the lack of product production process.
