[0002]

2. Description of the Related Art An electronic component supply device incorporated in an electronic component mounting machine for mounting electronic components on a substrate is constituted by arranging a number of parts feeders such as a tape feeder having an electronic component encapsulating tape wound on a mounting table. In the case of a rotary head type electronic component mounter, the parts feeder is reciprocated horizontally on the mounting table, while the electronic components of the parts feeder are taken up by the transfer head and transferred to the board, In the case of a one-by-one type electronic component mounter, the transfer head moves in the X and Y directions to take up the electronic components of the parts feeder and transfer and mount the electronic components on a substrate.

[0003]

As described above, each time the transfer head takes up the electronic components of the parts feeder, the remaining amount of the electronic components of the parts feeder gradually decreases. However, conventionally, the remaining amount management of the electronic components of the parts feeder has not been performed, so that, for example, at the time of stocktaking, troublesome management such as manually counting the electronic components remaining in the parts feeder has to be performed.

[0004]

According to the present invention, a parts feeder detachably mounted on a mounting table is connected to a control unit of an electronic component mounting machine main body, and the remaining amount data of the electronic components of the parts feeder is stored. A remaining amount detection of an electronic component, comprising: a reading device provided with an input memory and reading data in the memory; and a display unit connected to the reading device for displaying remaining data of the electronic component. Device.

(Operation) In the above configuration, the memory of the parts feeder mounted on the mounting table and the control unit of the electronic component mounter main body are electrically connected, and the remaining amount data of the memory is called to the control unit side. It is. In addition, the remaining amount of the electronic components in the parts feeder gradually decreases with the mounting of the electronic components. However, the consumption or remaining amount data of the electronic components is input from the control unit to the memory. Therefore, if the remaining amount data stored in the memory is read by the reading device and displayed on the display unit, the remaining amount can be easily known at the time of stocktaking or the like. In addition, during the mounting operation, when the remaining amount of the electronic components in the parts feeder becomes small or becomes out of stock, a buzzer may be sounded to notify the user.

When the parts feeder 1 is set on the table 56, the connectors 81 and 83 are connected, and the remaining amount data of the parts feeder 1 stored in the memory 80 is
Called by the control unit 84. As the transfer head 70 takes up the electronic components and mounts them on the board 66, the remaining amount of the electronic components in the parts feeder 1 decreases. When stopped, a signal is sent from the control unit 84 to the memory 80,
The consumption or remaining amount data of the electronic component is written.
Such exchange of signals between the memory 80 and the control unit 84 can be freely performed. In FIG. 8, reference numeral 90 denotes a reading device for reading data in the memory 80; 91, a connector; and 92, a display unit connected to the reading device 90.

The present electronic component supply apparatus has the above-described configuration, and the operation will be described next. The supply reel 4 is mounted on the mounting section 7 of the supply unit 2, and the tape 5 is pulled out from the lead-out section 31. Then, the cover tape 5d at the front end portion is peeled off from the base tape 5a, the base tape 5a passes through the gap L, and further passes through the cover material 44, and the pin hole 5 at the front end portion is formed.
c is engaged with the pin 42 of the sprocket 41. When the base tape 5a is pulled out in this manner, the cover tape 5d
Is separated by the separation section 27 and collected in the collection chamber 16.

In this way, the supply unit 2 of the tape 5
Is completed, the tape feeder 1 is set on the table 56, and the sprocket 41 is intermittently driven to feed the tape 5 at a pitch. Then, the electronic component P is taken up by the transfer head 70 and is transferred and mounted on a substrate (not shown).

When the operation proceeds and the tape 5 on the supply reel 4 runs out, the operation of the apparatus is stopped and the supply unit 2 is stopped.
And pulling it backward to separate it from the tape feed unit 3. Then, the cover plate 19 is opened to collect the cover tape 5d collected in the collection chamber 16, and the shaft 12 is removed to replace the supply reel 4.

When a new supply reel 4 is mounted on the mounting section 7, the supply unit 2 is connected to the rear of the tape feed unit 3, and the operation of the apparatus is resumed. Thus, according to the tape feeder 1, the exchange of the tape 5 can be performed very easily.

As described above, as the electronic components P of the parts feeder 1 are transferred and mounted on the substrate 66, the remaining amount of the electronic components P of the parts feeder 1 gradually decreases. Therefore, when the remaining amount of the parts feeder 1 becomes low, for example, by sounding a buzzer and notifying the worker to that effect,
The operator can prepare for setup change such as replacement of the parts feeder 1. When the remaining amount of the parts feeder 1 becomes small or disappears, the parts feeder 1 can be automatically replaced.

The remaining data of the electronic components P of the parts feeder 1 is written from the control unit 84 to the memory 80. Therefore, when it is desired to grasp the remaining amount data of the parts feeder 1 at the time of stocktaking, for example, the supply unit 2 is separated from the tape feed unit 3 and connected to the reading device 90 as shown in FIG. Then, the data in the memory 80 is read by the reading device 90 and the remaining amount data is displayed on the display unit 9.
2 is displayed. Of course, in this case, the memory 80 may be taken out of the supply unit 2 and only the memory 80 may be connected to the reading device 90.

In particular, in this means, since each parts feeder 1 has its own memory 80, the parts feeder 1 is removed from the table 56, and this parts feeder 1 is mounted on another electronic component mounting apparatus. Even when the electronic component mounting apparatus is set on the table of the table, the signals and data can be exchanged with the control unit of the electronic component mounting apparatus as described above. There is an advantage that the remaining amount of each parts feeder 1 can be managed.

The present invention is not limited to the above embodiment. For example, the present invention is not limited to a rotary head type electronic component mounting machine, and the transfer head may be moved in the X and Y directions.
It can also be applied to a one-by-one type electronic component mounting device that transfers and mounts the electronic components of the parts feeder on the mounting table to the substrate, and also applies to the parts feeder with an integrated supply unit and tape feed unit. You can do it.
