When using the component mounter having the above-mentioned configuration, it is necessary to store the array table data of the production model in the memory 22 in advance. In this array table data, basic drive conditions SD such as the number of drive of the mounting head, the number HPNO of each supply hopper 3 corresponding to the mounting position ML of the supply hopper 3 used for component supply, and the electronic from each supply hopper 3 The drive conditions such as the number of cut-out parts DNO, the part code PTC of the electronic parts to be accommodated in the supply hopper 3, the part type PTT, etc. are recorded.

When the above-mentioned sequence listing data is stored in the memory 22, it can be performed by key input from the keyboard 5, but as shown in FIG. 5, the sequence listing data represented by a bar code is prepared in advance. By setting it, it is possible to input sequence table data very easily.

Next, the processing of the main control section 21 at the time of inputting the sequence table data described above will be described in detail with reference to the processing flowcharts shown in FIGS. 6 and 7. That is, the main control unit 21 causes the CRT 4 to "specify the input method of sequence listing data. 1: keyboard input, 2: bar code input".
Is displayed to prompt the operator to specify the input method of the sequence listing data (S1). At this time, the operator uses the keyboard 5
Press the "1" or "2" key above and answer the input method. Next, the main control unit 21 determines whether or not a key input has been made from the keyboard 5 (S2), and when a key input has been made, determines whether or not the input key is "1" (S3). . As a result of this determination, when the input key is "1", the input process of the array table data from the keyboard 5 is executed (S4).

As a result of the determination in S3, the key input is "2".
In the case of, the main control unit 21 causes the CRT 4 to display “basic drive condition S
Scan the D bar code. Is displayed to instruct to read the barcode (S5).

Next, the main control section 21 determines whether or not the barcode has been read (S6). As a result of this determination, when the reading is performed, it is determined whether or not the reading result is normal (S7), and when the reading is not performed normally, "reading failure. Read the barcode again. "Please do." Is displayed on the CRT 4 (S8), a buzzer sound is emitted from the confirmation sound generation unit 27 to instruct rereading (S9), and the process proceeds to S5.

If the result of the determination in S7 is that the barcode reading result is normal, the main control unit 21 causes the confirmation sound generation unit 27 to generate a click sound (S10) and stores the input data in the memory. 22 (S1

A message "Please read the barcode of the data at the mounting position n." Is displayed on the screen to instruct to read the barcode (S13).

Next, the main controller 21 determines whether or not the barcode has been read (S14). As a result of this determination, when the reading is performed, it is determined whether or not the reading result is normal (S15), and when the reading is not performed normally, “Read failure. Read the barcode again. "Please do." Is displayed on the CRT 4 (S16), and a buzzer sound is emitted from the confirmation sound generation unit 27 to instruct rereading (S17).
Process shifts to.

As a result of the determination in S15, if the barcode reading result is normal, the main control unit 21 causes the confirmation sound generation unit 27 to generate a click sound (S18) and stores the input data in the memory. 22 (S1
9). Next, the main control unit 21 adds 1 to the variable n (S20), and then determines whether or not the input of the sequence listing data is completed (S21). As a result of this determination, if the input of the sequence listing data has not been completed, the process proceeds to S13, and if the input is complete, the input processing of the sequence listing data is terminated.

As described above, by preparing the list of the sequence listing data represented by the bar code in advance, the sequence listing data can be input very easily. It is possible to significantly reduce the time and effort required to input data, and to prevent input errors.

On the other hand, if the array table data is input to the component mounter main body 1, a list representing the array table data can be displayed on the CRT 4 or can be printed by the printer 8. Therefore, when the list of the sequence listing data represented by the bar code in advance cannot be created by another device, even if the first sequence listing data is input from the keyboard 5, the printer 8 described above after the input. The list can be printed out. As a result, when mounting components of the same production model on another component mounting machine, or when mounting components of the same production model at a later date, it is possible to very easily input the drive condition data. The time and effort required for inputting can be greatly reduced, and mistakes in inputting can be prevented.

If the above-mentioned list is printed on a label sheet and the label with the bar code is attached to the supply hopper 3 and a component bag containing spare electronic parts, the supply using the bar code is performed. Management of the hopper and electronic parts can be easily performed.

The configuration in this embodiment is an example,
It is not limited to this. For example, instead of the pen-type bar code reader 6, a bar code reader that automatically sequentially reads a plurality of bar codes of the entire list may be used.

Further, the sequence table data of a plurality of production models may be stored in the memory 22, and the required sequence table data may be arbitrarily selected from among these.

Further, although the present invention is applied to the multi-mount type component mounter in this embodiment, it is needless to say that the present invention can be easily applied to a one-by-one type component mounter.

Further, in this embodiment, the bar code is used as the identification code, but the identification code is not limited to this.

[0037]

As described above, according to claim 1 of the present invention, a list of sequence listing data using an identification code is created in advance so that the sequence listing data can be read by the identification code reading means. Since it can be stored in the storage means, it is possible to significantly reduce the time and effort for inputting the drive condition data from the keyboard every time the production model is changed, and to prevent erroneous data input. It has an excellent effect that it can be done.

According to the second aspect, in addition to the above effect, the sequence listing data stored in the storage means can be output as a list represented by an identification code. Even for the production model for which the sequence listing data is input from the next time, or for other electronic component mounting systems that mount components of the same production model, easily enter the sequence listing data using the above list. It has an excellent effect that it can.

Further, according to the third aspect, in addition to the above effect, since the bar code which has been developed and has been generalized is used as the identification code, the device cost can be reduced.
