Detailed Description of the Invention [Table of Contents] Overview Industrial application field Conventional technology (Figs. 5 and 6) Problems to be solved by the invention Means for solving the problem (Fig. 1) 1) Example (FIGS. 2, 3, 4) Effects of the Invention [Outline] Creation of Numerical Control Data for Component Mounting Required for Automating the Process of Mounting Components on Boards such as Printed Wiring Boards and Ceramic Circuit Modules For the method, in order to improve the assembly efficiency of the board, when creating the component mounting numerical control data, a mounting table storing mounting component placement information for each board on which components are mounted, and a plurality of boards each. And a loading order table storing the loading order to the mounting machine is prepared. The board types are sequentially read from the loading order table from the first loading order, and the component names are read out from the mounting table corresponding to these boards in the component mounting order. Unless the read component name is already written in the channel setting table, the channel number and the component name to be stored in this channel are written in the channel setting table in correspondence with each other. For each board, the mounting data of the component for which the channel number is determined is written in the component mounting numerical control data table while designating the component number by the channel number.

[Industrial Application Field] The present invention relates to a method for creating numerical control data for component mounting necessary for controlling a process of mounting components such as ICs on a substrate such as a printed wiring board and a ceramic circuit module. About.

2. Description of the Related Art In recent years, automatic assembly of products has become widespread on factory production lines and the like. This assembly process includes a work process of mounting components on a product main body (for example, a board). When this component mounting process is automated, each component is stored in a predetermined location (channel), then the component is taken out from this storage channel as needed, and this component is automatically mounted sequentially to the required position on the board. Will be done. In such an automatic operation, since control is performed based on numerical data, it is usually necessary to create numerical control data for mounting components.

[Prior Art] FIG. 5 is a conceptual diagram of an IC automatic insertion machine conventionally used for mounting an IC as a component on a substrate. In FIG. Each of the channels is a channel for storing an IC (hereinafter simply referred to as a component) as a component, and different components are stored in the channels 1-1 to 1-96, respectively.

Also, 2-1 to 2-96 correspond to each channel 1-1 to
1-96 are gates which are opened as necessary to send out parts, and parts 3-1 to 3-96 are provided for each channel 1-1 to 1-96, respectively. ~
This is a passage sensor that detects that the sheet has been sent from 2-96.

Reference numeral 4 denotes a transport belt for transporting the components sent from each of the channels 1-1 to 1-96 to the side of the substrate 7 described later, and reference numeral 5 denotes a guide section for guiding the components to an insertion head 6 described later. The guide unit 5 is also provided with a skewing sensor 9, and 6 is an insertion head for inserting a component provided at the tip into a substrate 7 described later. The insertion head 6 can hold the component vertically to a substrate 7 described later, and the axis in this state (the axis perpendicular to the substrate 7)
The component can be rotated around the vertical axis, and the component can be inserted into the substrate 7 by moving up and down.

Reference numeral 7 denotes a board (printed board) into which components are inserted, and reference numeral 8 denotes an XY table on which the board 7 is mounted. The XY table can move the substrate 7 in the X direction and the Y direction while holding the substrate 7 in a certain plane (usually a horizontal plane).

For automatic control of the IC automatic insertion machine configured in this way,
Requires numerical control data for mounting (inserting) parts (ICs). Therefore, numerical control data for component mounting has been created.

FIG. 6 is a diagram for explaining a conventional method for creating numerical control data for component mounting. In this case, different types of boards (printed boards; Pt boards) A, B, C, and D are respectively applied to the boards. The case where various components are mounted will be described as an example. Also, in this example, an appropriate number of substrates A are assembled, and then,
An appropriate number of the substrates B, C, and D are assembled in this order.

In FIG. 6, reference numerals 11, 12, 13, and 14 denote mounting tables (for example, CAD data) of the substrates (Pt plates) A, B, C, and D, and the types of the substrates A to D are different from each other. , The mounting tables 11 to 14 are also different from each other, and the mounting tables 11 to 14 include the type of the board (Pt type),
For each mounting order, the symbol attached to the component, the mounting position (X, Y) of the component, the mounting angle (θ), and the type of the component (component name) are written.

Also, 21, 22, 23, and 24 are channel setting tables created corresponding to the mounting tables 11 to 14 for each of the boards A to D, and include a channel number (channel No.) and each of these channels. The type (part name) of the part to be stored is written.

And, 31, 32, 33, and 34 are mounting machine data created based on the mounting tables 11 to 14 and the channel setting tables 21 to 24 so as to be compatible with an actual production machine, that is, component mounting numerical control data. (NC data table or NC data). In this NC data table, each of the boards A to D
Along with the NC data name assigned corresponding to
The mounting position (X, Y), mounting angle (θ), and channel number (channel No.) are written.

In FIG. 6, the number of components to be mounted on each of the boards A to D is about 5 to 7, and the number of channels is No. 1 to
Although there are six and six, this is set small for the sake of convenience in explanation, and the number of mounted components and the number of channels are actually much larger than this. For example, as shown in FIG. 5, the number of channels is about 100 (96 in FIG. 5).
There are various types of components to be mounted, although they are within the range of the number of channels. And the number of mounted components may be much larger than this.

Assume that the mounting tables (CAD data) 11 to 14 have been created in advance.

In the conventional method of creating numerical control data for component mounting, a different channel setting table is provided for each type of each of the boards A to D, and each NC data is created corresponding to each of the channel setting tables. I was

That is, first, the mounting table 11 relating to the board A is taken out. The mounting table 11 includes, for each mounting order, symbols attached to components (represented by IC1 to IC6) and data (X, Y) of coordinates (X, Y) of a mounting position of each component (IC1 to IC6). The data (shown by numerical values in the table), the data of the angle (θ) to be mounted (shown by numerical values in the table), and the types (part names (ac) of the parts (IC1 to IC6)) are written. Here, the component names are written in the order of c, a, b, a, c, a.

Then, a channel setting table 21 is created corresponding to the mounting table 11. This channel setting table 21
Indicates that the component name of c is written in channel No. 1, the component name of a is written in channel No. 2, and the component name of b is written in channel No. 3.

At the same time, the NC data table 31 is created by CAD / CAM automatic conversion based on the mounting table 11 and the channel setting table 21. In this NC data table 31,
The data (X, Y, θ) that make the data of the coordinates (X, Y) and angle (θ) of the mounting table 11 for each mounting order compatible with the actual production machine by automatic CAD / CAM conversion, and the channel setting The channel number to be used in each mounting order obtained from the table 21 is written.

When the data creation for the board A is completed as described above,
Next, data is created for the substrate B in the same manner as described above.

That is, a channel setting table 22 of the board B is created corresponding to the mounting table 12 of the board B, and the CAD /
The NC data table 32 is created by CAM automatic conversion.

Further, for the boards C and D, the channel setting tables 23 and 24 and the NC data tables 33 and 34 are created corresponding to the mounting tables 13 and 14 in the same manner as described above.

When the data creation for each of the boards A to D is completed in this way, subsequently, the operation of the automatic IC insertion machine is started. Before starting the operation of this automatic IC insertion machine, it is necessary to first carry out a work for storing the corresponding parts in each of the channels 1-1 to 1-96 (so-called "setup change").

Therefore, first, when assembling the board A,
The setup change for the board A, that is, the parts corresponding to the respective channels 1-1 to 1-96 are stored based on the channel setting table 21 of the board A. Usually, this setup change is not automatic, but is performed manually by an operator.
The component of c is stored in channel No. 1, the component of a is stored in channel No. 2, and the component of b is stored in channel No. 3.

Then, the operation of the automatic IC insertion machine is started to assemble the board A. The IC automatic insertion machine controls a computer on the basis of the NC data table 31 while maintaining a predetermined position on the board A. Insert and mount the parts.

This will be described with reference to FIGS. 5 and 6, first,
In the mounting order 1, the gate of the channel No. 1 is opened to take out the part c. After the part c is conveyed by the conveyor belt 4, the guide part 5 grips the predetermined part of the insertion head 6, and the NC data table 31 On the basis of the data of X, Y, and θ, the component c is mounted on the substrate A while the insertion head 6 and the XY table 8 are operated.
Insert and implement. Then, in mounting order 2, channel 2
The component a is mounted in the same manner as described above, and the components are mounted on the NC data table 31 from the mounting order 3 to the mounting order 6 in the same manner.

When the assembly of a predetermined number of boards A (mounting of required components) is completed in this way, the operation proceeds to the assembly of board B.

In this case, the setup is changed based on the channel setting table 22 for the substrate B. The setup change here is also manually performed by the operator.

After the setup change, the IC automatic insertion machine is operated to automatically insert the IC for the substrate B.

Subsequently, in the assembling of the substrate C and the subsequent assembling of the substrate D, the work of the setup change is performed on the basis of the channel setting tables 23 and 24, and the NC data tables 33 and 34 are stored in the NC data tables 33 and 34 as described above. On the basis of this, the IC automatic insertion machine is operated to automatically insert the IC for the substrate C and to automatically insert the IC for the substrate D.
Performs automatic IC insertion.

[Problems to be Solved by the Invention] However, in such a conventional method of creating numerical control data for component mounting, each of the channels 1-1 to 1-96 is corresponded based on the corresponding data (channel setting table). It is necessary to perform a setup change operation to re-store parts to be replaced every time the type of board to be assembled is changed, but this setup change operation is manually performed by a worker for a large number of channels. Therefore, there is a problem that it takes a long time to work, and the assembly efficiency of the substrate is greatly deteriorated.

The present invention has been made in view of such problems,
An object of the present invention is to provide a method for creating numerical control data for component mounting, in which the number of operation steps such as setup change can be reduced and the efficiency of assembling a board can be greatly improved.

[Means for Solving the Problems] FIG. 1 is a principle block diagram of the present invention.

In FIG. 1, reference numeral 10 denotes a substrate (Pt
This is a mounting table that stores mounting component arrangement information for each type of board), and this mounting table is created in advance. Here, the mounted component arrangement information is a symbol attached to the component, a mounting position (X, Y) of the component, a mounting angle (θ), and a type of the component (component name), which are written in the mounting order.

Reference numeral 20 denotes a channel setting table created in correspondence with the mounting table 10, in which the type (part name) of the component to be stored is written corresponding to each channel (indicated by a channel number).

Numeral 30 is component mounting numerical control data (NC data table) created based on the mounting table 10 and the channel setting table 20 so as to match an actual production machine (production line). A mounting position (X, Y), a mounting angle (θ), and a channel number (channel No.) are written for each mounting order along with the NC data name assigned to the type of the board.

Reference numeral 40 denotes a loading order table that stores the loading order of the plurality of substrates into the mounting machine, and is created in advance.

60 creates the channel setting table 20 based on the mounting table 10 and the loading order table 40, and
This is an arithmetic unit that can create the NC data table 30 based on 10 and the channel setting table 20.

[Operation] First, the board types A to E are sequentially read from the first loading order from the loading order table 40 prepared in advance, and these boards (A in this case) of the mounting table 10 prepared in advance are read. The component names a to c are sequentially read from the corresponding mounting table 10 in the component mounting order.

Then, the component names a to c are already stored in the channel setting table 20.
Is written in the channel setting table 20 for determining which channel No. 1 to 6 the part is to be stored in, while preventing new writing from being performed, the channel numbers 1 to 6 and the channel of this channel number Are written in correspondence with the component names a to c to be stored.

Subsequently, for each of the boards A to E, the mounting data X, Y, and θ of the component for which the channel numbers 1 to 6 to be stored in the respective channel setting tables 20 have been determined are converted into the corresponding channel numbers 1 to 6.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

Note that the method of creating numerical control data for component mounting according to the present embodiment uses, as shown in FIG.
In an IC automatic insertion machine used to mount ICs,
It can be used to create numerical control data for mounting (inserting) an IC. Since the configuration and operation of this automatic IC insertion machine have already been described in the prior art, the description is omitted here.

FIG. 2 is a block diagram (principle block diagram) showing a flow of creating each data table according to one embodiment of the present invention.

In FIG. 2, reference numerals 11 to 14 denote mounting tables (CAD data) each storing mounting component arrangement information for each type of board (Pt board) on which components are mounted. , 12 is a mounting table for the board B, 13 is a mounting table for the board C, and 14 is a mounting table for the board D. Here, the mounted component placement information is a symbol attached to the component, a mounting position (X, Y) of the component, a mounting angle (θ), and a type of the component (component name).
Etc., and are written in the order of mounting. These mounting tables 11 to 14 are created in advance.
The mounting tables 11 to 14 are typically represented by reference numeral 10.

Reference numerals 25 to 29 denote channel setting data tables (channel setting data tables) created corresponding to the mounting tables 11 to 14, respectively, and components to be stored corresponding to the respective channels (No. 1 to 6). Names a to h are written. These channel setting tables 25 to 29 are typically
Represented by 20.

35-39 are mounting machine data [numerical control data for component mounting (NC data) based on the mounting tables 11-14 and the channel setting tables 25-29, respectively, so as to be compatible with the mounting production machine (production line). Table or NC
Data)], for example, obtained by CAD / CAM conversion. In the NC data table, the mounting position (X, Y), mounting angle (θ), channel number (channel No. ) Is written. The NC data tables 35 to 39 are typically represented by reference numeral 30.

In FIG. 2, the IC mounted on each of the boards A to D is shown.
Has about 5 to 7 channels, and the number of channels is No. 1 to
Although there are six and six, this is set small for the sake of convenience in explanation, and the number of mounted ICs and the number of channels are actually much larger than this.
For example, as shown in FIG. 5, the number of channels is about 100 (96 in FIG. 5), and accordingly, the types of ICs to be mounted are also within the range of the number of channels, but are various. It has become. Also, the number of mounted ICs may be much larger than this.

In FIG. 2, the substrate E is omitted.

Further, although not shown in FIG. 2, in implementing the method of creating numerical control data for component mounting of this embodiment,
The loading order table 40 (see FIG. 1) is also used. The loading order table 40 is a table that stores the loading order of the plurality of boards A to E to the mounting machine, and is created in advance. Further, although not shown in FIG. 2, the present component mounting numerical control data creating method is executed through the arithmetic unit 60 (see FIG. 1). The arithmetic unit 60 has functions of a loading order counter, a mounting counter, and a channel setting counter.

Here, the method for generating numerical control data for component mounting according to the present embodiment will be specifically described with reference to FIG. 2 and FIG. 3 which is a flowchart illustrating an embodiment of the present invention. The transition of the creation of the channel setting data table will be described with reference to FIG.

First, the loading order counter is set to 0 (see step a1 in FIG. 3), then 1 is added to this loading order counter (see step a2), and then the loading order data is read (see step a3). At the start of the creation, when the process first comes to step a3, the loading order counter is 1, so the loading order table 40 prepared in advance (see FIG. 1)
Thus, the type of substrate data whose input order is 1 is read. In this case, since the loading order is substrate A → substrate B → substrate C → substrate D → substrate F, in this step a3, the substrate A is read as data.

Then, in the following step a4, it is determined whether or not to end the creation of the NC data table. Here, it can be determined whether the loading order corresponding to the value of the loading order counter set in step a2 is in the loading order table 40, or whether the data of the substrate is input in the corresponding loading order.

If the data can be read in step a3, the process proceeds to step a5 without terminating, and the mounting table is searched from the Pt plate types in the loading order. The Pt plate type is a type of a blink plate, that is, a substrate. Here, since the Pt board type is A, the corresponding mounting table 11 is searched from the mounting table 10.

Then, the mounting counter is set to 0 (see step a6),
Subsequently, 1 is added to the mounting counter (see step a6). The value of the mounting counter corresponds to the order of mounting components. Therefore, at first, the mounting counter is 1. Then, in step a8, the mounting data is read. In this case, the mounting counter reads the data of 1. Specifically, the symbol IC1 attached to the component for each mounting portion, the X coordinate 10, the Y coordinate 10 of the mounting position, the mounting angle θ, and the mounting angle θ The part name c to be read is read.

Further, in the following step a9, it is determined whether or not to end the creation of the NC data table. Here, it can be determined whether or not the mounting order corresponding to the value of the mounting counter set in step a7 is in the mounting table 11.

If the data is read in step a8, the process proceeds to step a10 without terminating, and the channel setting counter is set to 0, and then the channel setting counter is set to 1 (step a1).
1). The channel setting counter corresponds to the channel number in the channel setting table (here, 25).

Then, in step a12, the component name data of the channel setting table 25 is read. In the initial state, no component name data is written in the channel setting table 25.
The part name is blank.

In the next step a13, it is determined whether or not the component name of the corresponding channel is blank, but since the component name is blank, the process proceeds to step 18 and the data is stored in the channel setting table 25. to add. Specifically, the component name data c is written to channel No. 1 of the mounting table.

Subsequently, the process proceeds to step a17. Here, the NC data table 35 is created. This creation is performed by CAD / CA using the mounting component placement information (X, Y, θ) of the mounting data read in step a8.
New mounting component layout information (X, Y, θ) obtained by M conversion
Is written into a predetermined portion of the NC data table 35, and the part name is converted into a channel number from the channel setting table 25 obtained in step a18, and then written.
Specifically, mounting component placement information (10, 10) obtained by CAD / CAM conversion of the data in the first order of the mounting data table 11
10,0) and the channel for storing the part c
No. 1 is written in the NC data table 35 in the first order.

When this is completed, the flow returns to step a7 again, and first, 1 is added to the mounting counter. Here, the mounting counter is 1
Changes from to 2. Subsequently, in step a8, the mounting data corresponding to the mounting counter 2, that is, the mounting data table
Read the data in the second order of step 11 and finish (step a
The process proceeds to step a10 without performing step 9), setting the channel setting counter to 0, and then setting the channel setting counter to 1 (step a11). Then, in step a12, the channel setting table 25, that is, the component name data of the channel setting table 25 is read. At present, when this is read, the component name data c is written in the table No. 1.

Therefore, in the next step a13, it is determined that the component name of the corresponding channel is not blank, and the process proceeds to step a14, in which it is determined whether or not to end. There is a corresponding channel (here, channel No. 1). It is determined that the process is not to be terminated, and the process proceeds to the subsequent step 15 where the component name of the mounting data is compared with the component name of the channel setting table 25. Here, the component name data a in the second order of the mounting data table 11 is compared with the component name c written in the channel No. 1 of the channel setting table 25.

If it is determined in the next step a16 that the compared component names are the same, the process proceeds to step a17. If not, the process returns to step a11. Now, the respective component names are a and c, which are different from each other, so that the process returns to step a11.

Then, in step a11, 1 is added to the current channel setting counter 1 to set the channel setting counter to 2, and
Proceeding to step a12, the component name data of channel No. 2 is read. Here, since channel No. 2 is blank,
At step a13, the process proceeds to step a18 to add data to the channel setting table 25. That is, the channel
Write the component name a in No.2.

Then, proceed to step a17, in the same manner as described above,
This time, the mounted component placement information (that is, 10, 20, 0) and the component a used for this are written in the second order of the NC data table 35.

Next, as described above, the process returns to step a7. This time, 1 is added to the mounting counter 2 to set the mounting counter to 3, and data is added to the channel setting table 25 as described above, and The corresponding NC data table 35 is created.

In other words, the mounting data in the third order in the mounting table 11 is read (step a8), and after proceeding from step a9 to a10, each step of step a11 → a12 → a13 → a14 → a15 → a16 → a11 is repeated, and step a11 is repeated. Sets the channel setting counter to 3. Then, when the channel setting data of channel No. 3 is read (step a12), since the component name is blank, the process proceeds from step a13 to step a18, and data is added to the channel setting table 25 as described above. (That is, the part name b is assigned to channel No. 3 in the channel setting table 25).
), And in the following step a17, a third order of the NC data table 35 is created in the same manner as described above (that is,
Write data 20, 30, 0, 3).

Then, next, returning to step a7 again, this time, 1 is added to the mounting counter 3 to set the mounting counter to 4, and
As described above, data is added to the channel setting table 25 and the corresponding NC data table 35 is created.

That is, when the mounting data in the third order in the mounting table 11 is read (step a8), the component name data is a. Therefore, the process proceeds to step a9 → a10, and steps a11 → a12 → a
After going through each step of 13 → a14 → a15 → a16, the process returns to step a11. Here, the channel setting counter becomes 2, and thereafter, the process proceeds to steps a11 → a12 → a13 → a14 → a15 →, and in this step a15, the component name of the mounting data is compared with the component name of the channel setting table 25. Then, since the component name data a in the fourth order of the mounting data table 11 is the same as the component name a written in the channel No. 2 of the channel setting table 25, the process proceeds to step a17 based on the determination in step a16. Then, the NC data table 35 is created.

Specifically, in the fourth order of the NC data table 35, the mounting component placement information (20, 30,
In addition to writing new mounting component placement information (20, 30, 0) obtained by CAD / CAM conversion of (0), the corresponding component name (components used in the fourth order) from the currently written channel setting table 25 Name) a is converted to channel No. 2 and written.

Thus, in the fourth order, the channel setting table 25
No data is added to the file.

Subsequently, returning to step a7, this time, 1 is added to the mounting counter 4 to set the mounting counter to 5, and data is added to the channel setting table 25 and the corresponding NC data table is set in the same manner as described above. Make 35. Also in this case, the component name c used in the fifth order is already the channel N
Since it is written in o.1, here, step a8 → a
9 → a10 → a11 → a12 → a13 → a14 → a15. Since the fifth component name c of the mounting data is the same as the component name c of the channel No. 1 in the channel setting table 25, the following step a1 is performed.
Proceed from step 6 to step a17 to select the fifth
The order is created in the same manner as described above.

Therefore, data is not added to the channel setting table 25 here.

Subsequently, returning to step a7, this time, 1 is added to the mounting counter 5, the mounting counter is set to 6, and the mounting data is read here (step a7). Because it is written to table 25,
As described above, only the creation of the corresponding NC data table 35 is performed without adding data to the channel setting table 25.

Subsequently, returning to step a7, if 1 is added to the mounting counter 6 and the mounting counter is set to 7, there is no corresponding number.
Return to 2. At this time, the channel setting table 25 and the NC data table 35 are created as shown in FIG.

Then, at step a2, 1 is added to the loading order counter 1 and the loading order counter is set to 2, and the loading order data 40 is read. In the second loading order, the substrate is B, so that the steps a4 to a5 Then, the table 12 of the board B is searched, and the data of the data from the mounting counter 1 in the same manner as described above, that is, from the first order of the mounting table 12, is transferred to the channel setting table 26 as described above. Addition and creation of the corresponding NC data table 36 are performed.

The writing to the channel setting table 26 is performed by adding information on the substrate B to the already written channel setting table 25. Therefore, the channel setting table 26 is the same as the channel setting table 25 when writing is started.

For example, in the first order of the mounting table 12, the component name is "a", and this "a" is already No. 2 of the channel setting table 26.
As described above, the data is not added to the channel setting table 26, and the corresponding NC data table 36 is created in the first order (that is, the data 10, 50, 0,
2) only.

In the subsequent second order of the mounting table 12, the component name is d, and since this d has not yet been written in the channel setting table 26, the channel No. 4 of the channel setting table 26 In addition to adding d as part name data, the corresponding NC data table 36 is created in the second order (that is, data 30, 40, 90, and 4 are written).

In the subsequent third order of the mounting table 12, the component name is b, and since this b has already been written in No. 3 of the channel setting table 26, the data to the channel setting table 26 is Of the corresponding NC data table 36 in the third order (ie, data 50, 30, 0, 3
Only).

Furthermore, in the fourth order of the following mounting table 12, the component name is e.
Since this has not yet been written to the channel setting table 26, as described above, this time, as part name data, the channel No. 5 of the channel setting table 26
And the fourth of the corresponding NC data table 36
The order is created (that is, the data 70, 20, 180, and 5 are written).

4 In the fifth part of the subsequent mounting table 12, the component name is b, and this b is already in the channel setting table 26.
No. 3 is written in the same manner as described above, without adding data to the channel setting table 26.
Fifth order creation of NC data table 36 (that is, data 9
0, 10, 0, 3).

In this manner, the second loading order (that is, the substrate B)
When the creation of the channel setting table 26 and the NC data table 36 is completed, the process returns from step a9 to step a2 again. In step a2, 1 is added to the loading order counter 2 to set the loading order counter to 3, and the loading order data 40 is read. Since the substrate is C in the third loading order, the process proceeds from step a4 to step a5. Then, by searching the mounting table 13 of the substrate C,
As described above, the process proceeds from the mounting counter 1, that is, from the first order of the mounting table 13 to the sixth order, and as described above, this time, data is added to the channel setting table 27, and The corresponding NC data table 37 is created.

Writing to the channel setting table 27 is performed by adding information on the substrate C to the already written channel setting table 26. Therefore, the channel setting table 27 is the same as the channel setting table 26 when writing is started.

As can be seen from the mounting data of this mounting table 13,
The component names used here are four types, a, b, c, and e, all of which are already written in the channel setting table 27. As a result, no data is added to the channel setting table 27. Will not be done. Therefore, NC
Only the data table 37 is created in the same manner as described above, and the channel setting table 27 is replaced with the channel setting table 26.
Is the same as

In this manner, the third loading order (that is, of the substrate C)
When the creation of the channel setting table 27 and the NC data table 37 is completed, the process returns from step a9 to step a2 again. In step a2, 1 is added to the loading sequence counter 3 to set the loading sequence counter to 4, and the loading sequence data 40 is read. Since the substrate is D in the fourth loading sequence, the process proceeds from step a4 to step a5. Then, by searching the mounting table 14 of the substrate D,
As described above, the process proceeds from the mounting counter 1, that is, from the first order of the mounting table 14 to the seventh order, and as described above, this time, data is added to the channel setting table 28, and The corresponding NC data table 38 is created.

As described above, the channel setting table 28 is the same as the channel setting table 27 when writing is started.

Here, the component names a, b, and c in the first to third orders of the mounting table 14 are already assigned to the channel setting table 28, respectively.
In the first to third orders, only data is written in the corresponding order in the NC data table 38.

Then, in the following fourth order, the component name is g,
Since this g has not yet been written in the channel setting table 28, the channel setting table
G is added to channel No. 6 of 28 as part name data, and data is written in the corresponding NC data table 36 in the fourth order.

In the subsequent fifth order, the component name is g, which has already been written in the channel setting table 28.
Only writing of data in the fifth order of the NC data table 38 is performed.

Further, in the following sixth order, the component name is h, and this h has not been written in the channel setting table 28 yet, so that the channel setting table 28
Want to add as part name data to However, since all the channels (No. 1 to No. 6) of the channel setting table 28 are written, a channel overflow occurs,
The part name data h cannot be written.

This will be described with reference to FIG. 3. If it is desired to add h as part name data, steps a11 → a12a → 13a
The cycle of → 14a → 15a → 16 → a11 is repeated, and when the channel setting counter reaches 7, this channel setting counter 7
There is no channel No. corresponding to “(No.
Is up to 6.) Therefore, in step a14, the process is terminated, and the process proceeds to step a19.

In this step a19, the channel setting data table 2
Clear the data of No. 8 and newly set the channel setting data table 29 in the initial state where no part name is written.
Set.

When clearing such data of the channel setting data table 28, a setup change is required.

Then, the NC data table 38 is cleared and a new NC data table 39 is created (step a20).

That is, returning to step a3, the channel setting data table 29 and the NC data table 39 are created from the mounting table 14 in the fourth insertion order in the same manner as in the first insertion order described above (see FIG. 2). .

Then, when the channel setting data table 29 and the NC data table 39 have been created up to all the input orders in such a procedure, the creation is completed in step a4 and the process ends.

The transition of the creation of such a channel setting data table is shown in FIG. 4, but in FIG. 4 a portion marked off by a large X (that is, the substrate from the Pt plate type C to the Pt plate type D). Only at the time of change), a setup change is required,
It can be seen that setup change is not required when changing the substrate from the Pt plate type A to the Pt plate type B and from the Pt plate type B to the Pt plate type C. In addition, for example, a change of the substrate from the Pt plate type D to the Pt plate type E is not shown in FIGS.
Also in this case, it is considered that there are many places where setup change is unnecessary.

In this way, the work of the setup change which requires a long working time can be greatly reduced, so that there is an advantage that the efficiency of assembling the printed board can be greatly improved.

In this embodiment, the channel setting data table
20 and numerical control data for component mounting (NC data table) 30
Are performed in parallel for each channel, but the NC data table 30 may be created after all the channel setting data tables 20 in one input order have been created. In this case, for example, the channel setting data table 25 in the first input order in FIG.
After writing all data up to o.3, start to create the NC data table 35.

[Effects of the Invention] As described in detail above, according to the method for creating numerical control data for component mounting of the present invention, the number of man-hours at the time of setup change requiring a long working time can be greatly reduced, and thus the assembly of the printed board There is an advantage that efficiency can be greatly improved.

Claims (1)

(57) [Claims] A plurality of channels for accommodating different components are provided. Numerical control data for component mounting is prepared for taking out desired components from these channels and mounting the components at required positions on a substrate. In doing so, a mounting table (10) storing mounting component arrangement information for each board on which the component is mounted, and a loading order table (40) storing the loading order to the mounting machine for each of a plurality of boards are prepared. Then, the types of the boards are sequentially read from the first loading order from the loading order table (40), and the component names are sequentially read from the mounting table (10) corresponding to these boards in the component mounting order, and the component is assigned to which channel. The component names (a, b, c...) Read from the mounting table (10) are already written in the channel setting table (20) in the channel setting table (20) for determining whether to store the components. When a new channel is written, the channel number and the component name (a, b, c...) To be stored in the channel of the channel are written in such a manner that new writing is not performed. For each board, the mounting data of the component for which the channel number to be stored in the channel setting table (20) is determined is written in the component mounting numerical control data table (30) while designating the component number by the channel number. A method for creating numerical control data for component mounting, characterized in that:
