The present invention relates to an informatization system related to an automobile aluminum wheel production process, and in particular, to provide individual production information analysis data of a product so that individual history management of aluminum wheels can be performed in real time, and continuous quality control by utilizing rational process management information. The present invention relates to a production process management system through individual historical data management of automotive aluminum wheels to facilitate product quality improvement and to facilitate product tracking later, in order to comply with the Manufacturers' Liability Act (PL Act).

In general, the phenomenon of corporate survival depends on the ability to meet the needs of consumers regardless of the state of affairs due to the phenomenon of integration into “one market” by the rapidly changing environment, the globalization of the global economy, and the wave of information. The global age has arrived. Under these circumstances, the improvement of national income has raised the interests on consumer's product safety, health, etc., and as the complexity of consumer products is diversified, consumer damage spreads in the process of product use and consumption.

However, even if a consumer suffers physical or property damage due to a defect in the product, it is difficult to prove the existence of the defect, the causal relationship between the defect and damage, and the intention or negligence of the manufacturer in a non-professional state. Uneasy.

Therefore, as the necessity of introducing a modern liability law based on strict liability principle (no fault liability) in the position of strengthening the safety problem of the manufacturer, the PL law of the manufacturer's goods has been introduced and spread.

"Product Liability" means damages to the life, body or property of a consumer, user or third party due to a defect in a product, ie an industrially manufactured, processed product such as a car, household appliance, food, or pharmaceutical product. This means that the manufacturer, the seller, and anyone involved in the manufacture or sale is liable for civil damages.

Therefore, many companies are building an informatization system for the history management of their own production items, but due to the nature of the production process, it is difficult to establish a management system for each product.

Moreover, in the case of automobile aluminum wheels, it was a reality that individual management was difficult due to not only the production process but also the manufacturing process as well as the material and the characteristics of the production process. Therefore, there was a problem that it was difficult to cope with the PL law.

An object of the present invention for solving the above problems relates to an informatization system related to an automobile aluminum wheel production process, in particular, to provide individual production information analysis data of the product so that individual history management of the aluminum wheel in real time and a reasonable process Production process management system through individual historical data management of automobile aluminum wheels to improve quality of product through continuous quality control and facilitate product tracking by using management information, and to comply with PL law.

The above object and various advantages of the present invention will become more apparent from the preferred embodiments of the present invention described below with reference to the accompanying drawings by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view for explaining a position for placing a mark for recognizing specific product information on a car aluminum wheel for managing individual historical data of the car aluminum wheel according to the present invention.

In order to apply the present invention, a two-dimensional barcode is applied to an empty area A4 between an inner side spout A2 portion and a bolting hole A3 portion of an automobile aluminum wheel A1, as illustrated in FIG. Is to mark (A5). This part can mark two-dimensional bar code that can be managed separately in the production process of automobile aluminum wheels, and it is difficult to establish an individual management level production process management system by marking other areas.

This is important because the aluminum wheel is the standard for real time process control without any external influences in the whole production process.

2 is a flowchart illustrating a production process of an aluminum wheel based on a production process management procedure through individual historical data management of an automotive aluminum wheel according to the present invention.

In step B1, aluminum ingots, which are raw materials, are melted and cast to produce aluminum wheels (hereinafter referred to as "wheels").

Thereafter, when the wheel made in step B1 is transferred by a conveyor or the like, in step B2, it is determined whether the wheel arrives at the correct position through the sensor, and when it is determined that the wheel is seated at the correct position, the process proceeds to step B3.

In step B3, the initial information of the aluminum ingot, which is a raw material, and the cast aluminum wheel information are combined to generate an initial two-dimensional bar code, and the laser marking method is marked at the position described in FIG.

That is, during the process of step B1 described above, the initial information of the aluminum ingot, which is a raw material, and the casted wheel information are combined to generate a two-dimensional bar code initial content, and the information generated in step B3 is converted to each wheel ( The two-dimensional bar code A5 is laser-marked in the empty area A4 between the inner side spout A2 of A1) and the part of the bolt fastening hole A3.

In addition, the marking by the laser processing method to be presented as a means for the marking, but the present invention does not need to be limited to this bar, for example, a marking method can be possible using a mechanical marking machine, etc. It will be apparent that the marking work belongs to the technical scope of the present invention without departing from the technical spirit of the present invention.

The wheel marked through the process of step B3 is to read the two-dimensional bar code marked for each production process through the process of step B4 to check the work, and accordingly processing for each production process that requires the corresponding operation The process proceeds to step B5.

The process of step B5 is briefly described as follows: 'Press process for the spout of the wheel' → 'Non-destructive inspection for the wheel casting' → 'Heat treatment' → 'SHOT BLAST' → 'Automatic warehouse' → 'Processing' → ' LEAK TEST '→' Surface Treatment '→' Powder Coating '→' Fluid Coating '→' Front Finishing '→' Clear Coating '→' Balancing '→' Final Inspection '→' 'Packing' → 'shipping'.

At the same time as the processing operation according to the process of step B5 described above is performed in each processing process, by reading the two-dimensional bar code marked through the process of step B3 and temporarily storing the work history of the barcode and processing specification information, In step B7, the wheel serial number (S / N; serial number), processing equipment information, and process contents are matched and stored in the database (B7) when the processes of steps B5 and B6 are completed.

In addition, the same Wheel Serial Number (S / N) system was established to share information during outsourcing process through partner companies, thereby creating a Point of Production (POP) server database (D / B). (B8), and provide it to the upper processor (WMS, ERP) (B9).

At this time, the process of step B8 is a subcontracting processing information management system of a partner company, to establish a serial number (S / N) system through a two-dimensional bar code on the external aluminum wheel, and data management function for the main processing and construction methods After matching with the serial number (S / N) and the data managing the delivery and shipment information, the database is constructed when the product shipment bar code is issued.
