2. Description of the Related Art FIG. 5 shows a conventional method for manufacturing a series of taping electronic components which is of interest to the present invention.

As shown in FIG. 5 (a), a plurality of chip-shaped electronic components 1 are housed one by one in a plurality of cavities 3 provided in a tray 2.

Next, as shown in FIG. 5 (b), display by tampo printing is applied. That is, by pressing the tampo 4 toward the plurality of electronic components 1,
A desired display is provided on the surface of each electronic component 1. For example, an ultraviolet curable ink is used to give this indication.

Next, as shown in FIG. 5C, the tray 2
The plurality of electronic components 1 held by are placed in an ultraviolet curing oven, and the above-mentioned ink is cured by being irradiated with ultraviolet rays 5 therein.

Next, as shown in FIG. 5D, a plurality of electronic components 1 are taped. That is, the tape 6 for holding the plurality of electronic components 1 in a state of being distributed in the longitudinal direction is prepared. The tape 6 has electronic components 1
There is provided a cavity 7 for accommodating each one. By operating the suction chuck 8 in the direction shown by the arrow 9, the electronic components 1 in the cavities 3 of the tray 2 are transferred into the cavities 7 of the tape 6 by a predetermined number. The tape 6 is intermittently fed by a predetermined length, and the above-described operation is repeated.

In this way, the taping electronic component string 10 is obtained as shown in FIG. 5 (e). After the electronic component 1 is inserted into the cavity 7, the cover sheet 11 is attached onto the tape 6 so as to close the upper opening of the cavity 7 as indicated by an imaginary line. FIG. 5E shows a state in which the display of “A1” is given to each surface of the electronic component 1. In addition, such a display mode can be arbitrarily changed.

[0008]

However, the above-described method of manufacturing the taping electronic component series 10 leaves room for further improvement in terms of efficiency and labor saving. That is, from the display giving step to the taping step, the plurality of electronic components 1 are handled while being held by the tray 2. Since one tray 2 holds only a finite number of electronic components 1, it is difficult to carry out such a process continuously because the tray 2 must be replaced when carrying out the above process. is there. Further, the work of carrying a plurality of trays 2 is also required. further,
It is necessary to transfer the electronic component 1 into the cavity 3 of the tray 2. This transfer operation is a complicated operation in the transfer operation, which is a preparatory step for rapidly manufacturing the taping electronic component train 10.

Therefore, an object of the present invention is to provide a method of manufacturing a series of taping electronic components, which can save labor and can efficiently proceed the process.

[0010]

According to the present invention, a series of taping electronic components is manufactured through the following steps without using the tray described above.

First and second rotors, each having a plurality of first and second holding portions distributed on each peripheral portion, are used, and these rotors are arranged at different positions.

First, while rotating the first rotor intermittently, at the first position, a plurality of electronic components are sequentially supplied to each first holding portion, and each first holding portion is supplied with one electronic component. The electronic components are held one by one, a display is given to each electronic component at the second position subsequent to the first position, and each first component is displayed at the third position subsequent to the second position. Each electronic component held in the holder is taken out.

As described above, the plurality of electronic components taken out from the first rotor are sequentially supplied to the second rotor.

Next, in the second rotor, while rotating the second rotor intermittently, at the fourth position, a plurality of electronic components are sequentially supplied to the second holding portion, and each second holding portion is supplied. The electronic components are held in the unit one by one, and the electronic components held in the second holding units are taken out at the fifth position subsequent to the fourth position.

Next, in order to tap the plurality of electronic components, the plurality of electronic components taken out from the second rotor are directed toward the tape that holds the plurality of electronic components in a distributed state in the longitudinal direction. Are sequentially supplied.

[0016]

According to the present invention, while the first rotor rotates intermittently, a plurality of electronic components are supplied one by one to the first holding portion, and then each electronic component is given a display, , Each electronic component is taken out. Next, these extracted electronic components are supplied toward the second rotor, and while the second rotor rotates intermittently, a plurality of electronic components are
A plurality of electronic components taken out from the second rotor are sequentially supplied toward the tape for holding the electronic components in order to taping the electronic components in order to supply the electronic components. To be done.

[0017]

As described above, according to the present invention, the step of giving a display to each electronic component and the step of taping a plurality of electronic components according to the intermittent rotations of the first and second rotors are performed. proceed. Therefore, as long as the supply of the electronic components to the first rotor is not interrupted, these steps can be continuously performed, and the taping electronic component string can be efficiently manufactured. As a result, it is possible to reduce the cost of the taping electronic component series.

Further, as described above, it is possible to achieve the steps from the provision of the display to the taping with, for example, one device, and therefore the steps required to manufacture the taped electronic component series. Can be significantly simplified.

Further, since the first rotor and the second rotor are used and the display imparting step and the taping step are shared by these rotors, respectively, the first rotor is changed to the second rotor. The supply path for the electronic component to be headed can be used as a region for waiting the electronic component in order to absorb the difference in the processing capability between the two processes. Therefore, a plurality of electronic components can be smoothly flowed through both processes. Further, when an ultraviolet curable ink is used for giving a display, the supply path from the first rotor to the second rotor should be used as an area for drying and curing the ink. You can

1 is a plan view schematically showing an apparatus for carrying out a method for manufacturing a series of taping electronic components according to an embodiment of the present invention. This device is provided with a display adding unit 12
And a taping section 13.

In the display adding section 12, the parts feeder 14
Are placed, and a plurality of chip-shaped electronic components (not shown in FIG. 1) are loaded into the parts feeder 14. The plurality of electronic components sent out from the parts feeder 14 are fed in a tandem along the feed track 15 toward the first rotor 16 in a state of being oriented in a predetermined direction. A plurality of, for example, 50 recessed holding portions 17 are distributed on the peripheral portion of the first rotor 16 as shown in FIG. As shown in FIG. 3, the holding unit 17 holds the electronic components 1 one by one. A negative pressure is applied to each holding portion 17 via the suction passage 18,
Thereby, the electronic component 1 is positioned in the holding portion 17. In addition, in order to improve the positioning accuracy of the electronic component 1 in the holding portion 17, the suction passage 18 is preferably provided at a position deviated to one end of the holding portion 17.

The first rotor 16 is intermittently rotated in the direction shown by the arrow 19 in FIG. During such intermittent rotation, as described above, the plurality of electronic components 1 sent along the supply track 15 are
It is sequentially supplied to the holding unit 17.

The printing plate wheel 21 is arranged so as to partially overlap the first rotor 16. This plate wheel 21 is shown alone in FIG. FIG. 2A is a plan view of the printing plate wheel 21, and FIG. 2B is a front view of the same. A plurality of relief plates 2 are provided on the periphery of the printing plate wheel 21.
2 is formed. Further, the printing plate wheel 21 includes a reinforcing plate 23 made of metal, for example.

Such a printing plate wheel 21 has a letterpress 22
The surface on which is formed faces downward. The printing plate wheel 21 is intermittently rotated in a direction indicated by an arrow 24 in FIG. Further, an ink application section 25 for applying, for example, an ultraviolet curable ink to the relief plate 22 is provided at a position shown by an imaginary line.

Each time the first rotor 16 and the printing plate wheel 21 are intermittently rotated synchronously and stopped together,
The state shown in FIG. 4 is obtained. In this state, the pusher 28 having the spring 27 mounted thereon pushes up the electronic component 1 to bring it into contact with the relief plate 22. The spring 27 enables the electronic component 1 to contact the letterpress 22 with a constant pressure. The cover mask 29 moves up and down in conjunction with the operation of the pusher 28 described above. Therefore, when the pusher 28 moves downward after the display of the electronic component 1 by the relief plate 22 is finished, the cover mask 29 causes the electronic component 1 to move to the relief plate 2.
It acts to forcibly peel from 2.

Referring again to FIG. 1, the electronic component 1 provided with the display is sent to the third position 30 following the second position 26 according to the intermittent rotation of the first rotor 16. At the third position 30, the electronic component 1 held by the holder 17 is discharged to the supply track 31. In addition, between the second position 26 and the third position 30,
As shown by the imaginary line, the image sensor 32 is arranged,
As a result, the quality of the display given to the electronic component 1 is determined, and only the electronic component 1 that is determined to be a good product is supplied by the supply track 31.
It may be discharged to.

On the supply track 31, the electronic component 1 is
The surface with the display is facing upward. The supply track 31 passes through the inside of the ultraviolet curing furnace 33. Therefore, while moving on the supply track 31, the ultraviolet curable ink used for providing the display of the electronic component 1 is cured. The length of the supply track 31 is selected so that the ink is exposed to ultraviolet light for the time required for such curing. The electronic component 1 sent along the supply track 31 is supplied to the second rotor 34. In the second rotor 34, holding portions similar to the holding portions 17 provided in the first rotor 16 are distributed around the peripheral portion. The second rotor 34 has an arrow 3
As indicated by 5, it is rotated intermittently. During this intermittent rotation, at the fourth position 36, the electronic components 1 are sequentially supplied to the holding portions of the second rotor 34, and one electronic component 1 is held in each holding portion. To be done. Then, at the fifth position 37 subsequent to the fourth position 36, each electronic component 1 is taken out from the holder. Note that each electronic component 1 is held while being held by the second rotor 34.
May be performed.

In order to tap the electronic component 1, a tape 38 holding a plurality of electronic components 1 in a longitudinally distributed state is intermittently fed in a direction indicated by an arrow 39. Although not shown, the tape 38 has a plurality of cavities like the tape 6 (FIG. 5) described above.
As described above, the electronic components 1 taken out from the second rotor 34 are sequentially supplied into the cavity of the tape 38. Although not shown, for example, a push rod or a suction chuck is used for this supply. After the electronic component 1 is inserted into the cavity of the tape 38, a cover sheet is attached so as to close the upper opening of the cavity, whereby a desired taped electronic component string is obtained.

In the above-described embodiment, the taping electronic component series in which the electronic components are inserted in the cavity provided in the tape is manufactured, but other types of taping electronic component series, for example, a plurality of taping electronic component series on the tape are manufactured. The present invention can also be applied to a taped electronic component series in which electronic components are held via their lead wires.
