JPH0540791A - Automatic register method for parts data base - Google Patents

Abstract

PURPOSE:To considerably shorten the time required to register parts information in a data base of parts which supports production of a printed board in an electronic parts mounting machine. CONSTITUTION:Parts numbers and corresponding parts information are stored in a computer, and a program to analyze parts information is stored in the computer. Then, the parts number is read in (step 1), and the parts classification is discriminated (step 2), and the form and the packing type of parts are discriminated (step 3), and it is discriminated whether parts information is already registered in the parts data base or not (step 4), and parts information is automatically registered in the parts data base if it is not registered (step 5).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of registering component information in a component database for creating mounting data of an electronic component mounting machine for mounting electronic components on a printed circuit board.

[0002]

2. Description of the Related Art A component database is used to support production in electronic component mounting equipment. By utilizing this database, mounting data used by an electronic component mounting machine can be automatically generated or mounted on a plurality of equipments. It is used to automatically distribute parts.

An example of a conventional method of registering component information in the component database will be described with reference to the drawings.

FIG. 3 is a flow chart showing a conventional procedure for registering component information in a component database. First, the operator prepares a list of part numbers to be registered (step 1
1). Next, select an optional part number (step 12),
The catalog of the part is examined and the shape information and packing style information of the part are retrieved (step 13). Here, the shape information is vertical,
Horizontal and height dimensions, number of leads, lead pitch, electrode width,
The electrode length and the like are shown, and the packaging information indicates the taping direction, the tape width, the tape feed pitch, and the embossing depth in the case of tape supply, and the number of tray rows and the tray pitch in the case of tray supply. The retrieved data is manually entered in the parts database (step 14). This step 12 to 1
Repeat the procedure up to 4 for all parts you want to register.

[0005]

However, in the above method, although it is possible to register the component information in the database, a time-consuming process of investigating the component information one by one and inputting it by hand is required. There was a problem.

It is an object of the present invention to provide a parts database automatic registration method capable of significantly shortening the time-consuming process by storing a program for automatic registration in a computer.

[0007]

In order to achieve the above object, a parts database registration method of the present invention is a method for automatically registering a plurality of kinds of parts in a parts database.
The first step of importing and storing the part number into the computer, the second step of analyzing the imported part number, and the third step of automatically registering the shape and packing style information of the analyzed result in the parts database. By providing three steps, a plurality of parts are automatically registered in the parts database.

[0008]

With the above-described structure, the present invention has a program for analyzing a part number in a computer,
If the part number is clear, the shape and packing information of the part can be confirmed, so that it can be automatically registered in the parts database, and the information of each part can be checked manually from the catalog and registered manually in the parts database. This eliminates the need for time-consuming work processes and enables the effective construction of a parts database in a short time.

[0009]

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a flow chart showing the flow of processing of the parts database automatic registration method according to the present invention. The operator reads the part number to be registered in the parts database with a bar code (step 1). Next, determine what kind of product the read component is from a part of the component part number (step 2), and the component shape information (length, width, height, number of leads, lead pitch, electrode width, electrode length). And the information on the packing style (taping direction, tape width, tape feed pitch, embossing depth in case of tape supply, number of tray rows, tray pitch in case of tray supply) (step 3).
How to make this determination becomes clear from the part number as shown in FIG. That is, in FIG. 2, a character string consisting of twelve characters represents one row of the part number, and in this row, the three characters from the left are the product type of the part, the next three characters are the shape information of the part, and the last three characters are the last. The 1st character (that is, the 1st character at the right end) is the packaging information, and the last remaining 7th to 11th character strings are the electrical constants of the parts, such as the resistance value and the capacitor for resistors. Indicates the capacity. However, since the 4th to 6th three characters indicating the shape information include the information about the dimensions of the parts, they provide auxiliary information such as the tape feed pitch in the packing information. The arrow pointing to the right in FIG. 2 indicates that the shape information partially modifies the packaging information.

Next, it is confirmed whether or not the component information output as the determination result is already registered in the component database (step 4), and if it is not registered, it is registered in the component database (step 5). The steps 1 to 5 are repeatedly and sequentially registered for all parts to be registered. DB in FIG. 1 represents a database.

The method of fetching the part number may be manual input instead of the bar code.

[0013]

As described above, according to the present invention, by providing a part part number analysis program inside a computer, it is possible to reduce the time required to investigate the shape information and packing information of each part part one by one with a key code and manually input it. It becomes possible to eliminate such steps and automatically determine the shape information / packing style information of the target part only by clarifying the part number, and register it in the part database in a short time.
