Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method of assigning common symbols to parts assembled into one vehicle in an automobile production process.

(Prior art) In the automobile production process, for the purpose of identifying vehicles,
It has been conventional practice to assign a different body number to each vehicle by stamping or the like.

Various improvements have been made to the method of incorporating such vehicle identification symbols, for example, Japanese Patent Application Laid-Open No. 58-675
Publication No. 75 states that in order to be able to read vehicle model information even after painting, a paint containing ferromagnetic material is used to magnetize the magnetic material in a predetermined painted area to memorize the vehicle model information. A method is disclosed. There is also a known method of marking a vehicle with a vehicle identification symbol using a laser. For example, patent application No. 59-21950
No. 0 discloses an apparatus for printing on a vehicle using a laser.

Furthermore, in recent years, due to legal requirements, it has become necessary to assign a common symbol to each specific part incorporated into a vehicle.

(Problem to be solved) In order to meet this request, it is preferable in terms of reliability to attach a label that displays a symbol common to the vehicle to each part after the assembly of the vehicle is completed, but depending on the part, This makes it difficult to attach labels, which is disadvantageous in terms of workability.

Another option is to assemble the parts at a station, stamping each part or creating a label and pasting it on the parts, but this method is disadvantageous in terms of work efficiency, similar to the above method. be.

Furthermore, this method makes the work complicated and there is a risk that incorrect markings may be given to the parts.

(Means for Solving the Problems) The present invention has been constructed in view of the above circumstances, and is capable of reliably giving a common identification symbol to multiple parts of one vehicle, and The object of the present invention is to provide a method of assigning symbols to automobile parts in the automobile production process, which makes it easy to perform the work.

The present invention is a method for assigning symbols to automobile parts in an automobile production process, in which a common symbol is assigned to a plurality of parts incorporated in one vehicle, and the method includes: At the station, the symbol is given to the specific part, and at the station, a required number of labels are created that display the common symbol to be given to other parts to be incorporated into the vehicle, and the label is attached to the The present invention is characterized in that the label is temporarily attached to a specific part, and then sequentially attached to other parts at a station where the specific parts are assembled into the vehicle.

In the present invention, it is preferable that the specific parts to which the identification symbol of the vehicle is given are those that are delivered to the assembly line relatively early in the assembly process, such as an engine, a transmission, etc. Further, as a means for attaching an identification symbol to this specific part, a method of marking using a laser is preferable since the operation for attaching the symbol can be performed easily.

Preferably, when the symbol is assigned to this specific component, symbol display labels for other components are created at the same time.

(Effects of the Invention) According to the present invention, at a processing station for a specific part incorporated into a vehicle, an identification symbol is given to that specific part, and display labels for other parts are created all at once. This not only improves work efficiency, but also ensures the creation of identical labels. moreover,
Since the label is attached at the station where the parts to which the label is to be attached are assembled, the label can be attached easily and reliably.

(Description of Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

Referring to FIG. 1, an overview of the entire automobile production process to which the present invention can be applied is shown. In this example, a vehicle body 2 that has been painted at a paint factory 1 is transported to a vehicle assembly factory 3 via a transport line, various parts are assembled at a predetermined parts assembly station in the assembly factory 3, and a predetermined vehicle inspection line is installed. After taking the test,
