It is connected to the RT4 so that characters and the like can be displayed on the screen of the CRT4.

When using the component mounting apparatus having the above-described structure, the supply hopper 3 to be used for each production model of the circuit board 14 is prepared in advance, and the production model is set in the memory 22 in advance. . When the production model is set in the memory 22, it can be performed by key input from the keyboard 5, but it can also be performed by reading the barcode label 14a of the circuit board 14.

Next, the operation of this embodiment will be described. In the present embodiment, the supply hopper 3 is provided for each production model of the circuit board 14, and as described above, the supply hopper 3 is provided with the mounting position on the hopper mounting table 2 and the corresponding production model of the circuit board 14. Is attached to the barcode label 3e. As a result, since the supply hopper 3 can be managed for each production model, the mistake of the supply hopper 3 can be reduced.

When the supply hopper 3 is mounted on the mounting apparatus main body 1 or when the production model is changed and the supply hopper 3 is replaced, all the supply hoppers 3 are exchanged according to the production model, and the production model is changed. In the state where is set, the correctness of each supply hopper 3 is checked.

That is, the worker mounts all the supply hoppers 3 corresponding to the production model on the hopper mounting base 2 and then the CRT.
The bar code reader 6 reads the bar code of the supply hopper 3 at the mounting position shown in FIG. At this time, if a reading failure occurs, a display indicating this is displayed on the CRT 4. When the bar code of the supply hopper 3 is reliably read, the production model and the mounting position represented by the bar code read by the main control unit 21 are compared with the preset production model and the mounting position displayed on the CRT 4. ,
When these do not correspond, a buzzer sound is emitted and a message indicating the incorrect installation of the supply hopper 3 is CR.

It is possible to easily recognize the erroneous mounting of the supply hopper 3 and prevent the erroneous mounting of the supply hopper 3. Further, when the production model and the mounting position read from the bar code label 3e and the preset production model and the mounting position displayed on the CRT 4 match, a click sound is emitted,
The operator can easily recognize that the mounting position is correct.

The above-described operation is performed on all the supply hoppers 3, and the mounting apparatus main body 1 cannot be driven until the main control unit 21 determines that the mounting positions of all the supply hoppers are correct. Yes / No is displayed on CRT4.
Therefore, the mounting apparatus main body 1 is not driven in a state where the supply hopper 3 is erroneously mounted, and production of defective products can be prevented.

Next, the processing of the main control section 21 when the production model is changed will be described in detail with reference to the processing flowcharts shown in FIGS. 5 and 6. The main controller 21 is CR
The characters "Please specify the input method of the production model. 1: Keyboard input, 2: Bar code input" are displayed on T4 to prompt the operator to specify the input method of the production model (S
1). At this time, the operator presses the "1" or "2" key on the keyboard 5 and answers the input method. Then
The main controller 21 detects the input key of the keyboard 5 (S
2) It is determined whether the input key is "1" (S)
3). As a result of this determination, when the input key is "1", the production model by key input is acquired (S4). When the key input is "2", the main control unit 21 displays the message "Read the barcode on the circuit board." On the CRT 4 to instruct to read the barcode (S5), and then the bar. It is determined whether the code has been read normally (S6). If the result of this judgment is that the barcode was not read normally, the message "Could not read normally. Please read again." Is displayed on the CRT4 (S7) and a confirmation sound is generated. A buzzer sound is emitted from the unit 28 to instruct rereading (S8).

As a result of the determination in S6, when the barcode is normally read, the main control unit 21 stores the input production model in the memory 22 (S9). After that, the main control unit 21 displays the characters "Please read the barcode of the nth supply hopper" on the CRT 4 (S10). Next, the main control unit 21 determines whether or not the barcode is normally read (S11).
If the result of this judgment is that the barcode was not read normally, the text "Could not read normally. Please read again." Is displayed on the CRT 4 (S12) and a buzzer sounds. It is issued to instruct rereading (S13).

As a result of the determination in S11, when the barcode is normally read, the main control unit 21 generates a click sound (S14), and then the production model indicated by the input barcode is first. It is determined whether or not it matches the one set in (S15). If the production models do not match as a result of this determination, the characters "The production model of the nth supply hopper is different." Are displayed on the CRT 4 (S16), and a buzzer sounds to inform the above ( S17), and shifts to the processing of S10.

If the production models match as a result of the determination in S15, it is determined whether or not the mounting position represented by the input bar code matches the one previously instructed (S18).
If they do not match, the message "The supply hopper is installed at a wrong position" is displayed on the CRT 4 (S19), and a buzzer sounds to notify the abnormality (S20).
The process moves to 10.

Further, as a result of the determination in S18, when the mounting position represented by the input bar code matches the one previously instructed, it is determined whether all the bar codes of the supply hopper to be used have been confirmed. If the unconfirmed one remains (S21), the process proceeds to S10. When all the barcodes of the supply hopper to be used have been checked, the mounting machine body 1 is set to the operable state (S
22), and ends the production model change process.

As described above, according to the present embodiment, it is possible to automatically set the production model by reading the bar code attached to the circuit board 14, so that the input error of the production model can be prevented. You can Further, when the supply hopper 3 is not compatible with the production model or when the mounting position is incorrect, an abnormality is notified, so that it is possible to prevent erroneous mounting of these, and in the unlikely event that it is erroneously mounted. Since the mounting machine main body 1 cannot be driven, malfunction of the device can be prevented, production of defective products can be prevented, and productivity can be improved.

The configuration in this embodiment is an example,
The present invention is not limited to this, and if all of the supply hoppers 3 used for each production model are connected or integrally formed, it is possible to save the trouble of exchanging the supply hoppers and erroneously install the supply hoppers. Can be further prevented.

Even if the present invention is applied to a one-by-one type component mounter, almost the same effect can be obtained.

Further, in the present embodiment, the bar code label indicating the production model is provided on the circuit board 14, but the present invention is not limited to this, and the same effect can be obtained by providing it on the production instruction slip or the like. You can

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