2. Description of the Related Art Conventionally, for example, in an electronic component mounting machine for mounting electronic components on a substrate, a tape-shaped electronic component assembly formed by winding a tape-shaped holding member accommodating and holding a large number of electronic components on a reel is supplied. The parts cassette is mounted as a device, and the parts cassette is mounted in the parts supply unit of the electronic parts mounter in a predetermined order.
At the time of component mounting, the component supply section operates to sequentially position the parts cassettes holding the predetermined types of electronic parts at the parts pick-up position, and each parts cassette is a tape-shaped electronic parts assembly according to the mounting operation of the electronic parts. Are sequentially delivered to sequentially deliver the electronic components to the component extraction position, and predetermined electronic components are sequentially supplied to the component extraction position according to the mounting order.

A specific example will be described with reference to FIGS. 5 and 6. Reference numeral 1 denotes a component mounter, and a board on which a component is to be mounted is provided at a front portion thereof at an arbitrary position at a predetermined component mounting position C. A substrate positioning unit 2 for positioning the substrate so that the substrate is supplied to and discharged from the substrate positioning unit 2.
The board discharging means 4 is provided, and the component supply section 5 is provided at the rear of the component mounter 1. Between the board positioning unit 2 and the component supply unit 5, as shown in FIG. 6, the component is taken out at a predetermined component taking-out position A in the component supplying unit 5, and the component is taken at the component mounting position C in the board positioning unit 2. A rotary-type component mounting means 6 for mounting on is installed. Further, on the front surface of the upper part of the component mounter 1, a display means 7 composed of a monitor TV is arranged.

As shown by a phantom line in FIG. 6, it is provided on the upper part of the component supply unit 5 so as to correspond to the component take-out position A, and further at each component supply table 8.

A specific configuration example of the recording processing means 20 will be described with reference to FIG. The detection means 22 is the swing lever 18
A reed switch 27 arranged to detect an approaching movement of a permanent magnet 26 (see FIG. 2) attached to the free end of the
The processing operation means 23 and the storage means 21 are constituted by the circuit board 30 on which the IC 28 and other electronic parts 29 constituting the main part are mounted, and the transmission / reception means 24 is constituted by the coil 31. , These reed switches 27,
The circuit board 30 and the coil 31 are arranged in the synthetic resin case 25 to form a unit.

In the vicinity of the hand portion 12a for holding and transferring the parts cassette 10 of the robot 12, the parts stored in the storage means 21 transmitted to and received from the recording processing means 20 of the parts cassette 10. A reading means 32 for reading the name or the type of part is provided.

In the above structure, when the component assembly 13 is mounted on the parts cassette 10, the barcode 14 is read in advance by the barcode reader, and the component name, the component characteristic value and the component characteristic value of the component assembly 13 are held. The data such as the quantity is taken out from the parts database, and the storage means 2 in the recording processing means 20 of the parts cassette 10 is read / written by the reading / writing means.
These data are written in 1. The component name and the component characteristic value may be read from the barcode 14 and written in the storage unit 21.

The parts cassettes 10 are arranged according to the model of the circuit board and transported to the parts supply device standby table 11, and the robots 12 transfer the parts cassettes 10 to the parts of the parts supply unit 5 at the start of operation or when the models are switched. It is mounted at a predetermined position on the supply table 8 in a predetermined order. At that time, the robot 12
By reading and confirming the part name or the kind of the part from the recording processing means 20 of the parts cassette 20 that is mounted in large numbers by the reading means 32, it is possible to mount the parts cassette 10 by mistake and cause a mounting error. It can be surely prevented.

Instead of checking the parts cassette 10 by the robot 12 or in combination with this, after the mounting of all the parts cassettes 10 is completed, the mounting of the parts cassette 10 is checked on the side of the mounter 1. Good.
That is, the component supply base 8 is sequentially moved to read / write means 9
Each component name is read from the recording processing means 20 of each part cassette 10 (see FIGS. 5 and 6), and each component name of the read part cassette 10 and each mounting stored in the controller of the component mounting machine 1 are read. It may be possible to display the result on the display means 7 (see FIG. 5) by comparing with the part name at the position to determine whether each part is set at a predetermined position.

During the component mounting work, the swing lever 18 swings each time a component is picked up, and a pick-up detection signal is output from the detection means 22, and the processing calculation means 23 in each case outputs the storage means 2.
The component holding quantity stored in 1 is rewritten by subtracting 1 from it.

Further, during the component mounting work, the component outage check is appropriately performed. That is, the current value of the component holding quantity stored in the storage means 21 of each parts cassette 10 is read, and each component is cut out based on the usage quantity per board and the time required for mounting one board. Is calculated and displayed on the display means 7 (see FIG. 5). The parts cassette 10 that needs to be replaced is prepared based on the information about the parts shortage, and is installed on the parts supply device standby table 11.

Then, at an appropriate time, the parts cassette 10
Exchange. At this time, by exchanging the component supply base 8, the component mounting work can be exchanged without any interruption. When replacing this parts cassette 10,
The reading means 32 of the robot 12 allows the parts supply device standby stand 1
The parts cassette 10 is installed on the parts supply table 8 after the parts to be replaced are confirmed by reading the parts name or the kind of parts stored in the recording processing means 20 of the parts cassette 10 on the upper part 1. It is possible to reliably prevent a mounting error due to an error in the installation position of.

In the above embodiment, an example in which the parts cassettes 10 that run out of parts during the component mounting operation are detected each time, the parts cassettes 10 are prepared in the order of running out of parts, and installed on the parts supply device standby table 11 However, the parts cassettes 10 that are out of parts are estimated based on the mounting plan by the component mounting machine 1, and the parts cassettes 10 are randomly installed in advance on the parts supply device standby table 11, and the parts cassettes 10 are The reading position 32 of the robot 12 detects the installation position of the component supply device standby stand 11 of
When the parts cassette 10 on the parts supply table 8 runs out of parts, the robot 12 may select and replace the corresponding parts cassette 10.

In the above embodiment, the recording processing means 20 is used as the storage means. However, the bar code 14 provided on the parts assembly 13 is used as the storage means, and the robot 12 is provided with the bar code reader. Alternatively, the component name may be read.
