Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a component supply device for supplying various components such as electronic components to an electronic component mounting machine and a data processing device for the component supply device.

[0002]

2. Description of the Related Art A parts cassette conventionally used as a parts supply device for an electronic parts mounting machine for mounting electronic parts on a substrate is a reel of a parts tape in which a large number of electronic parts are held in a tape-shaped holder. The tape is wound around and mounted, and the component tape is sequentially fed out in accordance with the component mounting operation of the electronic component mounting machine to sequentially deliver the electronic components to the component removal position. By the way, when parts are supplied using a parts cassette, the parts mounting work is interrupted until the next parts cassette is prepared when the parts run out suddenly, and the operation rate of the electronic parts mounting machine is reduced. When the cassette is installed, the initial value of the number of mounted parts of each parts cassette is manually input to the control device of the electronic component mounting machine, and the control device is configured to rewrite the number of mounted parts according to the component mounting operation. ing.

[0003]

However, when manually inputting the initial value of the component mounting quantity as described above, tens to hundreds of parts cassettes are installed in a recent electronic component mounting machine. However, there is a problem in that it takes a lot of time and labor and there is a risk of erroneous input. On the other hand, it is conceivable to provide a storage unit for storing the initial value in each parts cassette and have the electronic component mounting machine read the initial value of the storage unit, but it is possible to rewrite the storage contents of the storage unit. Therefore, when the parts cassette removed from the electronic parts mounting machine is installed again, the parts mounting amount is unknown and the above problem cannot be completely solved.

In view of the above conventional problems, it is an object of the present invention to provide a component supply device and a data processing device for the component supply device which can always grasp the current value of the number of mounted components.

[0005]

In order to achieve the above object, the component supply apparatus of the present invention detects a component removal from the swing lever that swings in conjunction with the component removal operation and the movement of the swing lever. A detection unit, a transmission / reception unit that wirelessly receives and transmits the component information, a storage unit for storing the component information including the component mounting quantity, and a storage unit that rewrites the component mounting quantity in the storage unit based on a detection signal from the detection unit. And a processing operation unit for inputting / outputting the component information of (1) to / from the transmitting / receiving unit.

[0006]

According to the component supply device of the present invention, if the initial value of the component mounting quantity is stored in the storage means, the component mounting quantity stored in the storage means is rewritten by the processing operation means in response to the removal of the component. , You can always grasp its current value.
