The main controller 21 is connected to the keyboard 5 and the bar code reader 6 via the bus BS, and can receive the key input from the keyboard 5 and the bar code read by the bar code reader 6 as data. You can do it. Further, the main control unit 21 is C
It is connected to the RT4 so that characters and the like can be displayed on the screen of the CRT4.

When the component mounter having the above-mentioned configuration is used, the array table data of the production model is stored in the memory 22 in advance. When storing the sequence listing data in the memory 22, it can be performed by key input from the keyboard 5, but by storing the sequence listing data of the production model in a predetermined format on the magnetic floppy disk in advance, the floppy disk interface Sequence listing data can be easily input through the unit 27.

In the above-mentioned array table data, the model numbers and types of electronic parts to be accommodated in the respective supply hoppers 3 corresponding to the mounting positions of the supply hoppers 3 used for supplying the parts, and the electronic parts from the respective supply hoppers 3 The number of cutouts, the mounting position of electronic components on the circuit board 14, and the like are recorded.

When the supply hopper 3 is mounted on the mounting machine body 1, the mounting position of the supply hopper 3 is checked for correctness while the array table data of the production model is input. That is, when the switch 2d corresponding to an arbitrary mounting position is pressed after the supply hopper 3 is mounted on the hopper mounting base 2, the green LED 2b corresponding to the mounting position where the switch 2d is pressed is turned on. Thereby, the operator can arbitrarily specify the confirmation position, and the confirmation position can be clearly recognized.

Done When the bar code of the supply hopper 3 is reliably read, the model number of the electronic component represented by the bar code read by the main control unit 21 is compared with the array table data, and when this model number does not correspond to the mounting position, Red LED
2c is turned on. Thereby, the operator can easily recognize that the mounting position and the supply hopper 3 do not correspond to each other and prevent the supply hopper 3 from being erroneously mounted. Further, when the read model number and the sequence table data match, the LED 2b is turned off, and the operator can easily recognize that the mounting position is correct.

The above operation is performed for all the supply hoppers 3, and the mounting machine 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 machine 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 controller 21 when the above-mentioned supply hopper is mounted will be described in detail with reference to the processing flowchart shown in FIG. When the supply hopper is installed, the main control unit 21 displays the message "The device cannot be driven. Please check the supply hopper." On the CRT 4 to indicate that the mounting machine main unit 1 is in an undriveable state. After (S1),
It is monitored whether or not any one of the switches 2d arranged corresponding to the mounting position of each supply hopper 3 is pressed, and when any one of the switches 2d is pressed, the green LE of the corresponding position is monitored.
D2b is turned on to display the confirmation position of the supply hopper 3 (S3). Next, it is determined whether or not the barcode of the supply hopper 3 has been read (S4), and when the barcode has been read, it is determined whether or not the reading result is normal (S5). If the result of this determination is that the reading was not successful, the message "Reading failed. Please read the barcode again." Is displayed on the CRT 4 to instruct re-reading (S6), and the above S4 is executed. Process shifts to.

If the result of the determination in S5 is that the bar code reading result is normal, the main control unit 21 determines whether the model number in the read bar code matches that of the array table data ( S7) When they do not match, the red LED 2c corresponding to the mounting position of the confirmation target is turned on (S8), and the green LED 2b is turned off (S7).
9), and shifts to the processing of S2.

If the result of the determination in S7 is that the model number in the read bar code matches that in the array table data, the main control section 21 causes the green and red LEDs 2b corresponding to the mounting position to be confirmed, After turning off both 2c (S10), it is determined whether or not the supply hopper 3 to be used has been confirmed (S11). As a result of this determination, if all the confirmations have not been completed, the process proceeds to S2, and if completed, the CRT 4 displays that the mounting machine body 1 is in a drivable state (S12), and the supply is performed. The confirmation process of the hopper 3 is completed.

The configuration in this embodiment is an example,
It is not limited to this. For example, the supply hopper 3 may be designated by a keyboard or a program. Further, as a result of the confirmation, an LED may be provided to display that the mounting position of the supply hopper 3 is correct.

In this embodiment, the confirmation target position and the like are displayed using the LEDs 2b and 2c, but the present invention is not limited to this. For example, the same effect can be obtained even if one horizontally extending liquid crystal display or the like is provided on the front surface of the hopper mounting base 2 and a display is made at a position corresponding to each supply hopper 3.

Further, although the present embodiment is applied to the multi-mount type component mounter, it can be easily applied to a one-by-one type component mounter. In this case, it is preferable that the bar code label is attached to the component storage body or the supply device.

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