DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

The mounting inspection data creating apparatus of the present invention is shown in FIG.
As shown in, the component name or type of the component to be mounted and inspected, a name called a circuit number for distinguishing each component on the board, basic data on the mounting position including the position and orientation to be mounted, and the tolerance at the time of inspection. By inputting the inspection condition data in which the code regarding the value is specified, the machine data for automatically operating the mounting inspection device is created based on an appropriate database. Note that components normally mounted on a board cannot be mounted physically on top of each other. Therefore, if it is possible to distinguish by the mounting coordinate value, the mounting coordinate value may be used instead of the circuit number on the board. ..

Next, the specific structure and operation of the embodiment of the present invention will be described with reference to FIG.
The input basic data 1, which is given as D data, etc., sorts the mounting inspection parts by the type of the mounting inspection device while referring to the model list 2 which lists the types of applicable mounting inspection devices. The component-specific component coordinate value table 4 in which the inspection component and the coordinate value of the mounting position of the component and the circuit number are recorded according to the model of the mounting inspection device
Is formed. The input of the basic data 1 and the model allocation 3 can be configured to be performed automatically, semi-automatically to perform the model allocation 3 manually, or manually. It should be noted that an operation in which all the components are inspected by using one mounting inspection device is also conceivable, but in this case, the process of such distribution 3 may be omitted.

When the model-specific component coordinate value table 4 is formed, the equipment operation is performed via the equipment master database 5 which constitutes the equipment database based on the data specifying the model of the mounting inspection device among the recorded data. The database 6 is accessed, and the data regarding the operating characteristics of the mounting inspection apparatus is read. The equipment master database 5 records the access address to the equipment operation database 6 for each model, and the equipment operation database 6 records the operation characteristic data of the mounting inspection device that affects the mounting inspection operation.

Further, based on the type or name of the part recorded in the model-specific part coordinate value table 4, the part shape database 8 is accessed through the part master database 7 constituting the part database, and the part is classified for each part. The data regarding the shape is read. An access address for the component shape database 8 is recorded in the component master database, and data relating to various shapes of components is recorded in the component shape database.

Further, for each part recorded in the model-specific part coordinate value table 4, the conditions for inspecting the part are input based on the information items from the inspection condition data 9 and the inspection condition table 10 is entered. To create. Here, even if the same component name is used, the allowable condition at the time of inspection may differ depending on the mounting position on the circuit board, so it cannot be defined for each component name or type like the component shape. Therefore, the inspection code for indicating the inspection condition is set in the inspection condition table 10 for each circuit number of each component. Inspection condition table 1
The inspection code of 0 corresponds to the access address to the mounting inspection condition database 11, and the mounting inspection condition database 11 records data related to the inspection conditions such as the actual allowable value when inspecting the component.

As described above, the operation of reading out predetermined data from various databases based on the model-specific parts coordinate value table 4 is sequentially performed by the read / write processing means 12, and by this read / write processing means 12. Based on the read data, the individual component array table 13 in which the data of the model of the mounting inspection device, the type of the component to be mounted, and the mounting inspection condition are written is formed for each component.

When the individual component array table 13 is formed in this manner, the name of each component and the coordinate value of the mounting inspection position are sequentially read from the model-specific component coordinate value table 4, and based on the circuit number and the component name. The data read out from the individual component arrangement table 13 is converted into machine data 15 by the machine data conversion means 14. NC corresponding to the coordinate value is included in the machine data 15.
There are data, part data corresponding to the type of parts, and inspection condition data indicating allowable conditions at the time of mounting inspection.

Next, in the present embodiment, an address for the mounting apparatus is set in the equipment master database 5, operation data for each type of mounting apparatus is registered in the equipment operation database 6, and each part is classified at the time of model allocation 3 In addition, the mounting inspection device and the mounting device are separately assigned, and the information of both devices is included in the component-specific component coordinate value table 4, and the machine data conversion unit 14 for the mounting device is added to the machine data 15 for the mounting device. If the NC data of is also created at the same time, it can be used as a mounting data creation device for the mounting device. At this time, the component master database 7 and the component shape database 8 determined by the names and types of components can be commonly used. At this time, it is premised that the mounting inspection position and the mounting position are the same for each component.

[0021]

As is apparent from the above-described embodiments, according to the present invention, if the type of component, its mounting inspection position, the model of the mounting inspection device, etc. are input, it is necessary from various component databases and equipment databases. Data is read out, converted to machine data together with the mounting inspection position, and output.
Mounting inspection data can be created automatically.

Further, if a database for the mounting apparatus is additionally configured and the model of the mounting apparatus is input, a function of automatically creating machine data for the mounting apparatus using a common parts database is also available at low cost. Can be added easily.
