Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to the creation of NC data necessary for the operation of an electronic component automatic insertion machine, and in particular, it is unique to various incompatible automatic insertion machines.
The present invention relates to a printed board assembly NC data editing method suitable for automatically editing NC data according to the NC data format.

[Conventional technology]

The conventional NC data editing method cannot be used when a new automatic insertion machine is introduced, because even the products of the same manufacturer have different restrictions on the vehicle insertion machine depending on the model. Therefore, another NC data editing method had to be developed. As a similar technique, Japanese Patent Application Laid-Open No. 61-25212 discloses a method in which machining information of an NC machine tool is universally created so that it can be used in NC machine tools of different models. In this prior art, NC for similar NC machine tools
The codes and parameters in the data are replaced using a conversion table to create NC data for one machine from another machine.

[Problems to be solved by the invention]

Creating NC data for an electronic component automatic insertion machine is much more difficult than creating NC data on a normal NC machine tool. There are several types of automatic inserters that insert the same electronic components into a printed board, and the NC data items and NC data formats are usually greatly different for each automatic inserter. Also, in the case of a model that rotates the mounting board of the printed board to change the insertion direction of the electronic component, the coordinate system changes, so
It is necessary to recalculate the insertion coordinates of the electronic component. For this reason, it is not possible to argue that an automatic insertion machine and an ordinary NC machine tool are the same.

It is an object of the present invention to provide a printed board assembly NC data editing method that can be used universally even for electronic component insertion machines of different models that are not compatible.

[Means for solving problems]

The purpose of the above is to create a CN data for an automatic inserter that assembles and inserts electronic parts on a printed board. In the printed board assembly NC data editing method, the automatic inserter such as the component insertable direction and rotation method of each automatic inserter. The inserter information indicating the unique condition and the component mounting instruction information of the component supply unit of each automatic inserter are stored in the storage device, and the processing device is configured to store the automatic inserter when the target automatic inserter is designated. The inserter information and the component installation instruction information corresponding to the above are read from the storage device, and the XY coordinate values, the component insertion direction, the station number, etc. at the time of component insertion are read using these inserter information and the component installation instruction information. Calculated or determined data items and specified
This is achieved by outputting according to the NC data format.

[Action]

The inserter information indicating the conditions unique to the automatic inserter and the component mounting instruction information of the component supply unit of each automatic inserter are stored in the storage device in advance, and when the target automatic inserter is designated, the automatic inserter is specified. When the new automatic insertion machine is installed, the unique conditions of the automatic insertion machine are read because the information corresponding to is read out and used as the condition when calculating and determining the NC data item and output as the data according to the specified NC data format. By storing the parts attachment instruction information in the storage device, the NC data suitable for the automatic insertion machine can be edited by the same procedure.

〔Example〕

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

FIG. 3 is a block diagram of an NC data editing apparatus for carrying out an embodiment of the present invention. A magnetic disk device 2 for storing data, a display terminal 3 for input / output, and which electronic component is set in which station of a component supply section of an electronic component automatic inserting machine is mounted on a processing device 1 which performs various arithmetic processes. It is connected to a device 4 that outputs a setup list for instructing whether or not.

FIG. 1 is an explanatory diagram of an embodiment of the present invention. The magnetic disk device 2 has NC data format information 5, inserter information 6, component mounting instruction information 7, mounting information 8, and the processing device 1 performs processes A and B, which will be described later, to obtain each of these pieces of information.
The NC data 9 created from 5, 6, 7, and 8 are stored.

NC data format information 5 is the NC specific to the target inserter.
It is a data format. The inserter information 6 indicates whether the target inserter is a head rotation type that changes the component insertion method by rotating the head or a substrate rotation type that rotates the substrate, and the component insertable direction is 0 °. 90 °,
It is a constraint condition peculiar to the inserter such as 180 °, 270 ° in 4 directions or 0 °, 90 ° in 2 directions. Parts installation instruction information 7
Is the maximum number of stations of each inserter or sequencer and parts information of each station. Mounting information 8
Is information obtained by adding the information such as the insertion process and the insertion order of components necessary for mounting to the printed board CAD information. The user can specify the NC data format information 5, the inserter information 6, and the component mounting instruction information 7 from the terminal 3, and the created information can be stored in the magnetic disk device 2.

Using each of the above information 5, 6, 7, and 8 in the magnetic disk device 2, N
When creating the C data, the user specifies from the terminal 3 which process of which printed board, that is, which NC data of the automatic inserter to create. Thereby, the processing device 1
Reads necessary data from the magnetic disk device 2 (process A). Next, the processing device 1 performs NC data editing processing B for creating NC data of the target insertion machine from the read data.

The NC data editing process B includes a location conversion process b1 and an NC data format process b2. The location conversion process b1 is a process of calculating or deciding the data items required for NC data as described later, and the NC data format process b2 is the data item obtained by the location conversion process b1 according to the NC data format. This is the process of outputting.

In the location conversion process b1, the XY coordinate value that indicates the coordinate value when inserting the part, the molding dimension that indicates the pitch size of the part, the station that indicates which part is set in which station of the part supply part of the inserter Calculate or determine NC data items such as numbers, sequence numbers used to attach a series of serial numbers to NC data. For example, XY
When obtaining the coordinate values, it is necessary to obtain the XY coordinate values that match the conditions specific to the inserter. For some inserters, the XY coordinate value must be obtained as an absolute value (which always indicates the insert position of the part centered on the machine origin of the inserter), and an increment value (insertion of the insert part before one). There are some that must be obtained by displaying the insertion position of the part to be inserted this time around the position). In addition, there is a difference between the machine origin and the board origin.
The conditions such as whether or not the XY coordinate values are pulse converted are also different. Therefore, when obtaining the XY coordinate value, each of the above conditions is read from the inserter information 6 and the XY coordinate value is calculated according to the condition. That is, the inserter information corresponding to each target inserter is read and the XY coordinate value is calculated. In this way, each NC data item that meets the conditions of the target inserter is obtained from the inserter information and the component supply information.

In the NC data format processing b2, the NC data item obtained in the location conversion processing b1 is output according to the NC data format information 5 input by the user from the terminal 3. A method of creating NC data format information input by the user from the terminal 3 will be described with reference to FIG.

An NC data table and a control code table are required to create the NC data format. The NC data table is a table that stores the NC data items obtained in the location conversion process, and is composed of the contents of each NC data item and a convenient symbol for displaying the contents. The control code table is a table that stores the content of the control code used to indicate one operation delimiter of the insertion machine and the symbol that indicates this. The control code includes, for example, carriage return (CR) and line field (LF).

The user refers to these two tables and writes the information (data arrangement, index, number of digits, etc.) according to the NC data format of the target insertion machine from the terminal 3 into the NC data format table, thereby Create NC data format. For example, the NC data specification of a certain inserter is that "the index" X "is added and the X coordinate value is output in 5 digits, and the index" Y "is added and Y is added.
It is assumed that the coordinate value is output in five digits, the index "Z" is added, the station number is output in five digits, and finally the control code LF is output as a delimiter of the information. In this case, since the symbol on the NC data table showing the X coordinate value is "X", "X" is entered in the symbol column on the NC data format table. The heading (index) when outputting NC data is also "X", so enter "X" in the index column. Further, since the index "X" has one digit and the data has five digits, the value 1 and the value 5 are entered in each digit number column. Enter the Y coordinate value in the same manner. The symbol on the NC data table showing the station number is "S"
Since the index on the specification is "Z", these are NC
Fill in the corresponding fields in the data format table, and
Enter the number of digits in each column. Finally, enter the symbol "L" indicating the control code LF on the control code table and the number of data digits "1" in the corresponding columns.

When the information is created in the NC data format table as described above, the processing device 1 outputs the NC data according to this information in the NC data format processing b2. Also NC
In addition to the data, the allocation information according to the mounting information is output as a setup list.

As described above, according to the present embodiment, when editing the NC data for the electronic component automatic insertion machine, by giving the insertion machine information which is the constraint condition of the insertion machine and the component mounting instruction information, the condition The NC data items that meet the above are automatically calculated and determined, and the values are automatically edited according to the specified NC data format of the inserter. Therefore, NC data corresponding to the inserter can be immediately obtained. In other words, even if a new automatic insertion machine is introduced, there is no need to develop a new NC data editing system and the development man-hours can be reduced.

〔The invention's effect〕

According to the present invention, there is an effect that NC data compatible with an automatic insertion machine can be edited for general purpose.
