DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an electronic component supply device, in which data on the remaining amount of electronic components in a notebook feeder is input into a memory and can be recalled as needed. be.

(Prior art) An electronic component supply device that is incorporated into an electronic component mounting machine that mounts electronic components on a board has a mounting table with a number of parts feeders such as tape feeders wrapped with electronic component encapsulation tape arranged side by side. In the case of a rotary head type electronic component mounting machine, the parts feeder is moved horizontally back and forth above the mounting unit, and the electronic components on the parts feeder are taped and transferred to the board by the transfer head. Equipped with
In addition, in the case of a one-by-one type electronic component mounting machine, the transfer throat moves in the XY force direction to pick up the electronic component of the parts feeder and transfer and mount it on the board.

(Problems to be Solved by the Invention) As described above, each time the transfer head picks up electronic components in the parts feeder, the remaining amount of electronic components in the parts feeder gradually decreases. However, conventionally, the remaining amount of electronic components in the parts feeder has not been managed, so that, for example, when taking inventory, it is necessary to perform troublesome management such as manually counting the electronic components remaining in the parts feeder.

(Means for Solving the Problems) The present invention provides a parts feeder mounted on a mounting table such as a table moving table, connected to a control section of an electronic component mounting machine main body, and configured to control the amount of remaining electronic components of the parts feeder. It is equipped with a memory into which data is input.

(Function) In the above configuration, the memory of the parts feeder mounted on the mounting table and the control unit of the electronic component mounting machine main body are electrically connected, and the remaining amount data of the memory is called to the control unit side. Further, as the electronic components are mounted, the remaining amount of electronic components in the parts feeder gradually decreases, and the consumption amount or remaining amount data of the electronic components is inputted into the memory from the control section. Therefore, by calling up the remaining amount data stored in this memory on a playback device such as a monitor television, the remaining amount can be easily known at the time of inventory. In addition, during mounting work, if the remaining amount of electronic components in the parts feeder becomes low (or if the electronic components are out of stock), a buzzer can be sounded to notify that fact.

(Example) Next, the present invention will be described in detail with reference to the drawings.

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 up by the control unit 84. Furthermore, as the transfer head 70 picks up electronic components and mounts them on the board 66, the remaining amount of electronic components in the parts feeder 1 decreases. At the time of stopping, a signal is sent from the control unit 84 to the memory 80, and the consumed amount or remaining amount data of the electronic components is written. Such signal exchange between the memory 80 and the control unit 84 can be performed freely.

This device has the above-mentioned configuration, and its operation will be explained next.

The supply reel 4 is attached to the attachment section 7 of the supply unit 2, and the tape 5 is pulled out from the outlet section 31.

The head tape 5a is passed through the gap, and then the cover material 44 is passed through, and the pin hole 5C at the tip thereof is engaged with the pin 4.2 of the sprocket 41. When the hair tape 5a is pulled out in this manner, the cover tape 5d is peeled off by the peeling section 27 and collected into the collection chamber 16. After setting the tape 5 to the supply unit 2 in this way, set the tape feeder 1 on the table 56 and drive the sprocket 41 intermittently to load the tape 5.
Pinch feed. Then, the electronic component P is transferred to the transfer head 70
is ticked up and transferred and mounted on a board (not shown).

When the work progresses and the tape 5 on the supply reel 4 runs out, the operation of the apparatus is stopped, and the supply unit 2 is separated from the tape feeding unit 3 by being held and pulled rearward. Then, the cover plate 19 is opened to collect the cover tape 5d collected in the collection chamber 16, and the shaft portion 1
2 and replace the supply reel 4. After the new supply reel 4 is attached to the attachment section 7, the supply unit 2 is connected to the rear of the tape feeding unit 3, and the operation of the apparatus is restarted. Thus, according to this tape feeder 1, the tape 5 can be replaced extremely easily.

As mentioned above, the electronic components P of the parts feeder L are placed on the board 66.
As the parts feeder 1 is transferred and loaded, the remaining amount of electronic parts P in the parts feeder 1 gradually decreases. Therefore, when the remaining amount of the parts feeder 1 becomes low, if the blind worker is notified by, for example, sounding a buzzer, the worker can prepare for changes such as replacing the parts feeder 1. . Furthermore, the parts feeder 1 can be automatically replaced by detecting that the remaining amount of the parts feeder 1 is low or empty.

The memory 80 also stores information from the control unit 84 to the parts feeder 1.
The remaining amount data of the electronic component P is written. Therefore, when it is desired to grasp the remaining amount data of the parts feeder 1, for example during inventory, the supply unit 2 is separated from the tape feeding unit 3 and sent to the playback device 90, as shown in FIG. 91 is a connector of the playback device 90;
92 is a monitor television, the data in the memory 80 is input to the playback device 90, and the remaining amount data is input to the monitor television 9.
2. Of course, in this case, the memory 80 may be taken out from the supply unit 2 and only the memory 80 may be set in the playback device 90. In particular, in this means, since each parts feeder 1 has its own memory 80,
Even when the parts feeder 1 is removed from the table 56 and placed on the table of the mounting table of another electronic component mounting apparatus, the above-mentioned signal is not transmitted between the parts feeder 1 and the control unit of this electronic component mounting apparatus. Since parts feeders 1 and data can be exchanged, there is an advantage that the remaining amount of each parts feeder 1 can be managed while being freely set in any electronic component mounting apparatus.

The present invention is not limited to the above embodiments, and is not limited to rotary head type electronic component mounting machines, for example, by moving the transfer head in the XY force direction, the electronic components of the parts feeder of the mounting table are transferred and mounted on the board. The present invention can also be applied to a one-high-one type electronic component mounting apparatus, and can also be applied to a parts feeder in which a supply unit and a tape feeding unit are integrated.

(Effects of the Invention) As explained above, the present invention includes a parts feeder provided with a memory that is connected to the control section of the main body of the electronic component mounting machine and into which data on the remaining amount of electronic components in the parts feeder is input. Therefore, the remaining amount of electronic components in the parts feeder can be managed easily and advantageously.
