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

As shown in FIG. 5A, for example, 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. 5B, a display by tampo printing is applied. That is, when the tampon 4 is pressed 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.

[0005] Next, as shown in FIG.
Are placed in an ultraviolet curing oven, where the above-described ink is cured by being irradiated with ultraviolet rays 5.

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 contains the electronic component 1
Cavities 7 are provided for accommodating one by one. By operating the suction chuck 8 in the direction indicated by the arrow 9, the electronic components 1 in the cavity 3 of the tray 2 are transferred into the cavity 7 of the tape 6 by a predetermined number. The tape 6 is fed intermittently by a predetermined length, and the above-described operation is repeated.

In this manner, as shown in FIG. 5E, a series of taping electronic components 10 is obtained. After the electronic component 1 is inserted into the cavity 7, the cover sheet 11 is stuck on the tape 6 as indicated by an imaginary line so as to close the upper surface opening of the cavity 7. FIG. 5E shows a state in which “A1” is displayed on each surface of the electronic component 1. Note that such a display mode can be arbitrarily changed.

[0008]

However, the above-described method of manufacturing the series of taping electronic components 10 leaves room for further improvement in efficiency and labor saving. That is, a plurality of electronic components 1 are handled while being held by the tray 2 from the display providing process to the taping process. Since one tray 2 merely holds a finite number of electronic components 1, the tray 2 must be replaced in advance of the above-described process, and it is difficult to continuously perform such a process. is there. In addition, it is necessary to carry a plurality of trays 2. further,
An operation of transferring the electronic component 1 into the cavity 3 of the tray 2 is required. This transfer operation is a complicated operation in the transfer operation, which is a preparatory step, in order to manufacture the taping electronic component chain 10 quickly.

SUMMARY OF THE INVENTION 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 carry out the steps.

[0010]

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

A first and a second rotor having a plurality of first and second holding portions distributed at respective peripheral portions are used, and these rotors are arranged at different locations.

First, a plurality of electronic components are sequentially supplied to each first holding portion at a first position while the first rotor is intermittently rotated. In a state where the electronic components are held individually, a display is given to each electronic component at a second position subsequent to the first position, and each first electronic component is displayed at a third position subsequent to the second position. Each of the electronic components held by the holding unit 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, a plurality of electronic components are sequentially supplied to the second holding portion at the fourth position while rotating the same intermittently. Each of the electronic components held in each of the second holding units is taken out at a fifth position following the fourth position, with the electronic components being held one by one in the unit.

Next, in order to tap the plurality of electronic components, the plurality of electronic components taken out of the second rotor toward the tape holding the plurality of electronic components distributed in the longitudinal direction thereof. 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 unit, and then, a display is given to each electronic component. Then, each electronic component is taken out. Next, the extracted electronic components are supplied toward a second rotor, and a plurality of electronic components are formed while the second rotor rotates intermittently.
The plurality of electronic components taken out of the second rotor are sequentially supplied to the second holding unit, and then taped to hold the electronic components in order to tap the electronic components. Is 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 rotation of each of the first and second rotors. proceed. Therefore, as long as the supply of electronic components to the first rotor is not interrupted, these steps can be continuously performed, and a series of taping electronic components can be efficiently manufactured. As a result, the cost of taping electronic components can be reduced.

Further, as described above, since the steps from the provision of the display to the taping can be achieved by, for example, one apparatus, the steps required for manufacturing a series of taping electronic components are performed. Can be significantly simplified.

In addition, since the first rotor and the second rotor are used and the display providing step and the taping step are shared by these rotors, the first rotor and the second rotor are used. The supply path for the heading electronic component can be used as a region for waiting the electronic component in order to absorb the difference in processing capability between the two processes. Therefore, a plurality of electronic components can flow smoothly over both processes. Further, when an ultraviolet curable ink is used to give an indication, the supply path from the first rotor to the second rotor is used as a region for drying and curing the ink. Can be.

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

The display providing section 12 includes a parts feeder 14.
A plurality of chip-like electronic components (not shown in FIG. 1) are put into the parts feeder 14, for example. The plurality of electronic components sent from the parts feeder 14 are supplied to the first rotor 16 in a tandem state along the supply track 15 while being directed in a predetermined direction. As shown in FIG. 3, a plurality of, for example, fifty recessed holding parts 17 are distributed on the periphery of the first rotor 16. As shown in FIG. 3, the electronic component 1 is held by the holding unit 17 one by one. A negative pressure is applied to each holding unit 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 unit 17, the suction passage 18 is preferably provided at a position biased to one end of the holding unit 17.

The first rotor 16 is intermittently rotated in a direction indicated by an arrow 19 in FIG. During such an intermittent rotation, as described above, the plurality of electronic components 1 sent along the supply track 15 move to the first position 20 at the first position 20.
These are sequentially supplied to the holding unit 17.

The printing plate wheel 21 is disposed so as to partially overlap the first rotor 16. This printing 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 reliefs 2 are provided on the periphery of the printing plate wheel 21.
2 are formed. The printing plate wheel 21 includes a reinforcing plate 23 made of, for example, metal.

The printing plate wheel 21 includes a relief plate 22.
It is arranged with the surface on which is formed facing downward. The printing plate wheel 21 is intermittently rotated in a direction indicated by an arrow 24 in FIG. Further, an ink application unit 25 for applying, for example, an ultraviolet curable ink to the relief printing plate 22 is provided at a position indicated by an imaginary line.

As described above, at the first position 20, the electronic component 1 supplied to the holding portion 17 of the first rotor 16 is displayed at the second position 26 subsequent to the first position 20. Granted. The detailed structure at this second position 26 is shown in FIG.

Whenever 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 to which the spring 27 is attached pushes up the electronic component 1 and makes the electronic component 1 come into contact with the relief plate 22. The spring 27 allows the electronic component 1 to contact the relief 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 provision of the display to the electronic component 1 by the relief printing plate 22 is completed and the pusher 28 operates downward, the cover mask 29 causes the electronic component 1 to move the electronic component 1 to the relief printing plate 2
It acts to forcibly peel off from 2.

Referring again to FIG. 1, the electronic component 1 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 holding unit 17 is discharged to the supply truck 31. Note that, between the second position 26 and the third position 30,
As shown by the imaginary line, the image sensor 32 is arranged,
Thereby, the quality of the display given to the electronic component 1 is determined, and only the supply track 31 of the electronic component 1 which is determined to be a non-defective product is determined.
May be discharged.

On the supply track 31, the electronic component 1
The surface provided with the indication is directed upward. The supply track 31 passes through an ultraviolet curing furnace 33. Therefore, while moving on the supply track 31, the ultraviolet curable ink used for giving the display of the electronic component 1 is cured. The length of the supply track 31 is chosen so that the ink is irradiated with UV 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 parts similar to the holding parts 17 provided on the first rotor 16 are distributed around the periphery. The second rotor 34 has an arrow 3
As shown by 5, the rotation is intermittent. 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 the electronic components 1 are held one by one in each holding portion. Is done. Then, at a fifth position 37 subsequent to the fourth position 36, each electronic component 1 is taken out of the holding unit. Note that, while being held by the second rotor 34, each electronic component 1
May be measured.

In order to tap the electronic components 1, a tape 38 holding a plurality of electronic components 1 distributed in the longitudinal direction is intermittently fed in a direction indicated by an arrow 39. Although not shown, the tape 38 has a plurality of cavities, similar to 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 taping electronic component sequence is obtained.

In the above-described embodiment, a series of taping electronic components in which electronic components are inserted into a cavity provided in a tape is manufactured. The present invention can also be applied to a series of taping electronic components in which electronic components are held via their lead wires.
