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

FIG. 1 shows a system configuration of an embodiment for producing an electronic package. In FIG. 1, 1 is an external perspective view of the automatic insertion machine, and 2 is a control device such as a personal computer for controlling the automatic insertion machine 1. The automatic insertion machine 1 and the control device 2 are connected by a communication line 3. The control unit 2 has an interface unit 21 for taking a communication interface with the automatic insertion machine 1, a control unit 22 for controlling the operation of the control unit 2, a storage unit 23 for storing programs and data, and inputting a production plan and other data. An input unit 24, a display unit 25 such as a CRT, an external storage unit 26 for controlling an external storage unit such as a floppy disk,
These are connected via an address bus 27, a data bus 28 and a control bus 29.

FIG. 2 is a flowchart showing the operation of the electronic package production executed by the control device 2.
In FIG. 2, when the data of the production plan is inputted from the input unit 24 (step S1), it is confirmed whether or not the product name is already registered in the intermediate data file which is the source of the insertion data (step S2). If not, CAD data (data at the time of design) such as X and Y coordinates representing the position of the component to be mounted on the electronic package, an insertion angle, an inserted component name, and a circuit symbol are input (step S3).

At this time, it is checked whether or not the component name is registered in the component data file of the control device 2 (step S4). If the component name is not registered, the shape classification, external dimensions, number of pins, etc. of the component are determined. Is input (step S5). After the input of the component data, or when the component data has already been input in step S4, it is registered in the intermediate data file (step S6). After the registration in the intermediate data file, or in the case where the intermediate data (data to which the unique value such as the offset of the automatic component insertion machine is added) is already registered in step S2, the intermediate data of the electronic package to be produced is A primary selection to be set in the component supply unit (34 in FIG. 6) is performed, and the components and the input order are determined (step S).
7).

The method of determining the order of loading will be described with reference to FIGS. In this case, it is assumed that the maximum number of component types that can be set in the automatic component insertion machine 1 is four.

In FIG. 3 (a), PKG1, PKG
2, and PKG3 indicate types of electronic packages to be produced, and IC1 to IC7 indicate component types necessary for producing PKG1 to PKG3. Here, parts necessary for producing PKG1 and PKG3 are IC1, IC2, IC3, and IC4.
And the parts required to produce PKG2 are IC
1, IC5, IC6, and IC7. When producing electronic packages in the order of PKG1, PKG2, and PKG3 under these conditions, first, the automatic component insertion machine 1
C1, IC2, IC3, and IC4 are set, and other IC5, IC6, and IC7 are set-over parts to produce PKG1.

Next, the production of PKG1 ends, and PKG2
When the production shifts to IC5, instead of IC2, IC3, and IC4 set in the automatic component insertion machine, IC5, IC
6, and IC7 are set. That is, the parts are rearranged three times to produce PKG2. Next, PKG2
When the production of PKG3 is completed and PKG3 is produced, IC2, IC3 and IC4 are set instead of IC5, IC6 and IC7 set in the automatic component insertion machine 1. That is, the rearrangement of the components is performed again three times to produce PKG3. As described above, PKG1, PKG2, PKG
If electronic packages are produced in the order of 3, a total of six component replacements are required.

FIG. 3B is a diagram for explaining a setup operation for producing electronic packages in the order of PKG1, PKG3, and PKG2 under the same conditions as those described above. First, IC1, IC2, I
Set C3 and IC4 to produce PKG1. Next, the process shifts to the production of PKG3. Since the components required for producing PKG3 are the same as those of PKG1, there is no need to rearrange the components here. Then, when the production of PKG3 ends and shifts to the production of PKG2, IC2 instead of IC2, IC3 and IC4
5, IC6 and IC7 are set in the automatic component insertion machine 1. That is, the rearrangement of the components is performed three times in total. As described above, when a plurality of types of electronic packages are produced by one automatic component insertion machine, the amount of setup work for component rearrangement differs depending on the production order.

Referring to FIGS. 4 (a), 4 (b) and 4 (c), a procedure for determining a production order when a plurality of types of electronic packages are produced by one automatic component insertion machine will be described. I will explain. As shown in FIGS. 4A and 4B, PKG
When 1, PKG2, and PKG3 are produced by one automatic component insertion machine, there are seven types of components used. Also, this automatic component insertion machine has four component types (component set station) that can be set, and the station can freely set components in a component set fixing section for fixedly setting components. It can be divided into a part set and a free part. Under these conditions, when four types of components are set in the automatic component insertion machine, the usage frequency (PKG1, PKG
2, the frequency of use in producing PKG3).

In the case shown in FIGS. 4A and 4B, IC1, IC2, IC3 and IC4 are set in the automatic component insertion machine 1, and IC5, IC6 and IC7 are set-over components. In this way, first, set parts are determined. Next, as shown in FIG. 4C, for each of the electronic packages, a set number of set parts for each electronic package, a "number of intersection parts", The “number of set-over parts types” other than the parts is obtained. Then, the production order of the electronic packages is determined based on the number of intersecting parts and the number of set-over parts determined for each electronic package.

Next, with reference to FIG. 5, a method of determining the production order of the electronic packages based on the number of types of intersection parts and the number of types of set-over parts will be described. In FIG.
The electronic packages to be produced are PKG1 through PKG5.
There are seven types of components necessary for producing these electronic packages, namely IC1 to IC7. Here, as described above, the components are set in the automatic component insertion machine 1 in the descending order of use frequency, and the components to be set are set components (IC1 to IC4). Then, the “number of intersecting component types” and the “number of set-over component types” for the set component are obtained for each electronic package. Next, the electronic packages are sorted in ascending order of the obtained number of set-over component types. If the number of set-over parts is the same, electronic packages having the same set-over parts are sorted in descending order of the number of intersecting parts. The order sorted by these two conditions is referred to as the production order of the electronic package.
That is, under the conditions shown in FIG. 5, the production order of the electronic packages is PKG2, PKG5, PKG4, PKG3,
The order is PKG1. As a result, the amount of setup work for rearranging components is significantly reduced, and production efficiency can be improved.

In this way, the order of arrangement of components is determined (step S8 in FIG. 2). Next, when the insertion is completed in the previous stage, the parts are compared with the arranged parts, the final parts setup arrangement in the most efficient insertion order is determined (step S9), and the parts insertion order is determined (step S10). ).

Here, FIG. 6 showing a component insertion portion of the automatic component insertion machine 1 will be described. In FIG. 6, reference numeral 31 denotes a printed circuit board into which various components are inserted, and all components are mounted to form an electronic package. Reference numeral 32 denotes a printed circuit board, and the printed circuit board 31 is mounted in the X direction in the drawing.
X for moving and rotating in the Y direction
Table, 33 is an insertion head for inserting electronic components into the printed circuit board 31, and 34 is an insertion head 33 for inserting components.
Supply part to supply the printed circuit board 31 to the XY
A loader 36 for setting on the θ table 32 is an unloader for storing the printed circuit board 31 (electronic package) after the automatic insertion.

Also, commands and data are transmitted from the control unit 2 via the communication line 3 to control the components supplied from the component supply unit 34 to the insertion head 33 according to the insertion order. Automatic component insertion, such as control for setting on the table 32, control for moving and rotating the XYθ table 32 after setting the printed circuit board 31 on the XYθ table 32, and automatic insertion when the insertion position and the inserted component are synchronized. The entire machine 1 is controlled.

Printed circuit board 31 on XYθ table 32
Is a position detecting means (not shown) for optically detecting a position
Thus, the reference position in the X direction and the Y direction and the angle deviation θ between the reference position and the reference axis (for example, the Y axis) are detected.
As a detection method, for example, light is applied to a through hole of a substrate, and a hole position of the component insertion is detected using an image sensor such as a four-segment photo sensor or a CCD.
Then, the position data of component insertion, that is, data of X, Y, and θ, is transmitted from the automatic insertion machine 1 to the control device 2 so that the insertion head 33 can insert components accurately.

If the component mounted on the printed circuit board 31 is an IC, the position data on the printed circuit board 31 for the name of the IC is registered as intermediate data in the intermediate data file. FIG. 7A shows the format of the registered intermediate data. In FIG. 7A, the order of the components of the intermediate data is the order of the circuit symbols of the IC created by CAD. In this intermediate data, for example, the position data of the circuit symbol I01 is X = 2OO, Y = 1
500, θ = 0. In this case, it is assumed that the unit of numerical values of X and Y is 10 microns and the unit of θ is radian.

FIG. 9 shows a component (I0) on the printed circuit board 31.
1, I02,..., I06). The position of the component is determined with reference to the reference hole 31A for automatic insertion. When inserting the IC1 into I01, the insertion head 33 according to the above intermediate data
Parts can be inserted accurately by inserting them at a position of X = 2OO, Y = 1500 from the origin with zero angle deviation.

However, since the component arrangement on the printed circuit board 31 is not in the order of the circuit symbols, if the components are inserted in the order according to the intermediate data in FIG. Therefore, in order to reduce the interference of the insertion head and the insertion time, it is desirable to set the insertion order shown in P in FIG. Therefore, the above steps S9 and S10
In the above, a new component insertion order is determined in consideration of these. FIG. 7B shows the rearranged intermediate data in the new component insertion order. As is apparent from this figure, the order of insertion of components, ie, ICs,
., 02, I01, I03, I06,..., The insertion order shown in P of FIG.

FIG. 10 shows the component supply section 34, which is represented by a station number (Z number) for each part name. Therefore, based on the correspondence table shown in FIG. 7C, the product name is converted into the station number, and the data shown in FIG. 7B is converted into the format of the actual insertion data (step S11 in FIG. 2). FIG. 4D shows the converted actual insertion data.

In the printed circuit board 31 (so-called bare board before component mounting), the hole positions of component mounting hardly change in lots or between lots. However, a slight error occurs between the CAD data registered in the intermediate data file and the automatic component insertion machine that inserts a component when the automatic component insertion machine is initially set. Therefore, in step S12 of FIG. 2, it is determined whether or not the printed circuit board 31 supplied to the XYθ table 32 of FIG. 6 before component mounting is a board to be produced for the first time. Detecting the displacement by the detecting means,
Optical position correction for correcting X, Y, and θ data is performed (step S13). Next, the correction of the position data to the intermediate data file is fed back based on the circuit symbol (step S14). FIG. 8A shows the corrected intermediate data fed back. In this case, the position of the supplied substrate is changed from the position indicated by the reference intermediate data to X.
This shows that both the direction and the Y direction are shifted by 100 microns.

FIG. 8B shows the corrected actual insertion data obtained by converting the product name to the station number based on the corrected intermediate data shown in FIG. 8A. Thereafter, actual insertion is performed according to the corrected actual insertion data (step S1).
5). On the other hand, if the substrate supplied in step S12 is a substrate having a history of production in the past,
Actual insertion is performed without feedback to the intermediate data file (step S15).

As described above, the positional deviation of the printed circuit board produced for the first time is optically detected, and the hole position subjected to the optical position correction is fed back to the intermediate data file, so that the position correction is performed every time the reproduction is performed. Since accurate position data can be reused, the time required for optical position correction can be reduced, and the operation rate of the automatic component insertion device can be improved.

In this embodiment, a so-called IC inserter for inserting an IC as an automatic component insertion machine has been described. However, the present invention is not limited to this. For example, a radial inserter for inserting a radial component such as a capacitor or a transistor, a resistor or the like may be used. Of course, the present invention can be applied to an axial inserter for inserting an axial component or a chip mounter for assembling an IC chip.

In the present embodiment, the corrected intermediate data is fed back for each lot. However, the corrected intermediate data is fed back for each board supplied by using a high-speed arithmetic element in the control device. You may do it.
