BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component mounting method of supplying data required for its operation to each mounting facility of a mounting line to mount components by destination, and particularly, by using destination integrated operation data. The present invention relates to a mounting method and a device for creating destination integrated operation data.

[0002]

2. Description of the Related Art Conventionally, when mounting parts by destination, operation data of each mounting equipment of a mounting line is created for each destination based on the destination data, and each mounting equipment is based on the operation data. Is operated to mount components.

A conventional component mounting method using destination data will be described below with reference to FIG. In FIG. 5, reference numeral 21 denotes a substrate CA having information for identifying the mounting position.
D data, 22 is a mounting part instruction table for each destination for instructing whether to mount a mounting component for each circuit number for each destination, and 23 is operation data necessary for operating the mounting equipment for each destination. This is another operation data. When creating this destination-specific operation data 23, the board CAD data 2
Referring to the mounting part instruction table 22 for each destination based on 1, the board CAD data is created by deleting the data of the parts that are not mounted for each destination, and then the board CAD data for each destination is displayed on the mounting line. The destination-specific operation data 23 is created by allocating the mounting components so as to be balanced with respect to each mounting equipment, and determining the mounting order so as to minimize the mounting time in each mounting equipment.

Thus, the substrate CA of the same printed circuit board
When parts are mounted by destination based on the D data 21, data of parts that are not mounted at each destination are deleted from the CAD data based on the destination-specific mounting part instruction table 22, and each mounting facility is specified for each destination. The motion data 23 necessary for the motion of the above.

Further, with reference to the destination-specific mounted component instruction table 22, every time a printed circuit board at the destination is produced, a worker on site issues a skip command for prohibiting mounting of components that are not mounted by the mounting equipment. A method of producing a board for each destination by adding it to the operation data and operating each mounting equipment based on the operation data is also executed.

[0006]

However, in the above-mentioned conventional method, since the operation data is created for each destination, operation data is required for the same board CAD data as many as the destinations. It requires a great deal of effort to create data many times and the effort to manage the data for each destination, requires a lot of recording media, and mistakenly uses the operation data necessary for the printed circuit board to be produced. As a result, unnecessary parts are produced, and the part arrangement of each equipment is different in each operation data.Therefore, when the production is switched for each destination, a setup change work of the part arrangement occurs every time, and the operation rate due to the production stop. There was a problem that it decreased.

In addition, when a skip command for prohibiting mounting is added to the operation data of each mounting facility, the burden on the workers at the site is large, and more production stop time is required, resulting in a lower operating rate. In addition, there is a problem that a defective product is produced due to an error in adding a skip command.

In view of the above-mentioned conventional problems, the present invention does not require a great deal of labor to operate the equipment with the destination operation data to produce the board for each destination, and the operation rate of the equipment can be reduced. It is an object of the present invention to provide a component mounting method capable of improving and reducing the defective rate, and a destination integrated data creating apparatus therefor.

[0009]

According to the component mounting method of the present invention, the mounted components are grouped according to the mounting presence / absence pattern of each mounting component according to the destination, and a skip command for prohibiting mounting is determined for each group. To create a mounting component skip command correspondence table for each destination, distribute the mounting components to each mounting facility on the mounting line, and determine the mounting order at each mounting facility.
Generate the operation data of each mounting equipment to which the skip command is added by referring to the destination-specific mounting component skip command correspondence table,
A feature is that component mounting is performed based on the generated operation data.

Further, the destination integrated data creating apparatus of the present invention comprises means for reading board CAD data for specifying the mounting position on the board, means for reading a mounting database having information on parts and mounting equipment, and each destination. A means for reading the destination-specific mounting component instruction table that instructs the mounting / non-mounting of the mounting components by location, a means for grouping the mounting components by the mounting / non-mounting pattern of the mounting components by destination, and each group A means for creating a skip instruction correspondence table for each destination by deciding a skip instruction that prohibits mounting, a means for allocating the mounted components to each mounting equipment on the mounting line, and a mounting order for each mounting equipment And a means for generating operation data of each mounting equipment to which a skip command is added by referring to the destination-specific mounting component skip command correspondence table, The operation data, characterized by comprising means for writing the recording medium.

[0011]

According to the present invention, the operation data is not created for each destination, but the integrated operation data for the destination is created. Therefore, a great amount of labor of creating similar data is required. In addition, a lot of recording media and labor for managing the data for each destination are not required, and the setup work of the parts arrangement of the equipment by the production switching for each destination is not necessary, and the operation rate is improved. Further, since it is not necessary to add a skip instruction for prohibiting implementation to the operation data of the equipment, the operation rate is improved, and there is no error in adding the skip instruction, so that the defect rate is also reduced.
