[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic component taping device which is provided in connection with an electronic component assembling device and an inspection device and taps the electronic component after inspection onto a carrier tape.

[0002]

2. Description of the Related Art A conventional taping apparatus for an electronic component of this type will be described with reference to FIGS.

FIG. 5 is a perspective view of a main part showing the structure of the above-mentioned conventional electronic component taping apparatus.
Reference numeral 0 denotes a non-defective electronic component that has been assembled and inspected, and is aligned two by two at the same pitch as the storage holes 22 provided in the carrier tape 21 supplied from the carrier tape supply unit (not shown) and rotated. It is sequentially conveyed by the expression table 23.

[0004] The normal operation of the taping device for electronic components is as follows. As shown in FIG. 5, the rotary table 23 is rotated by a predetermined angle, and the electronic components 20A and 20B are transferred to the transfer position of the transfer unit 24. And the carrier tape 21 is intermittently fed by a pitch distance corresponding to two of the storage holes 22, and the empty storage holes 22A and 22B for storing the electronic components 20A and 20B are referred to the storage positions. The transported electronic components 20A and 20B are sucked and moved by the suction nozzles 25A and 25B of the transfer unit 24, and are stored in the empty storage holes 22A and 22B.

[0005] By repeating this operation, the electronic components 20 are stored two by two in the storage holes 22 of the carrier tape 21 without missing portions.

Next, FIGS. 6 and 7 show the storing operation of the electronic component 20 when one of the electronic components 20 transported two by two becomes defective in the assembling process or the inspection process, and is transported by only one electronic component. It will be described using FIG.

First, as shown in FIG. 6, when the electronic component 20B to be stored is located only behind the transport direction, this information is transmitted to the transfer unit 24 and the carrier tape supply unit (not shown) in advance. The transmitted intermittent feed operation of the carrier tape 21 is intermittent feed of a pitch distance of one storage hole 22, and only the empty storage hole 22A for storing the electronic component 20B is stored in the storage position corresponding to the suction nozzle 25B. And only the suction nozzle 25B of the transfer unit 24 is
The operation of sucking and storing 0B is performed, and after this operation is completed, the operation returns to the normal state operation.

Next, as shown in FIG. 7, when the electronic component 20A to be stored is located only in front of the transport direction,
Similarly, this information is transmitted to the transfer unit 24 and the carrier tape supply unit (not shown) in advance, and the carrier tape 2
1 intermittently feeds the same pitch distance of two storage holes 22 as in the normal state, and prepares an empty storage hole 22A for storing the electronic component 20A at a storage position corresponding to the suction nozzle 25A, Only the suction nozzle 25A of the transfer unit 24 suctions and stores the electronic component 20A.

When two electronic components 20 are conveyed next and there are no missing portions, the carrier tape 21 is intermittently fed by a pitch distance corresponding to one storage hole 22 to operate in a normal state. Returning, as described above, when there is only one rear, the intermittent feeding of the carrier tape 21 is not performed because the empty storage hole 22B is already prepared at the storage position corresponding to the suction nozzle 25B. Instead, the transported rear only electronic component 20 is stored via the suction nozzle 25B, and then returns to the normal operation.

As described above, the conventional electronic component taping apparatus is configured such that the electronic component 20 is accommodated in the accommodating hole 22 of the carrier tape 21 by controlling the feeding operation of the carrier tape 21 without missing portions. Met.

[0011]

However, in such a conventional taping device for electronic parts, even if three or more electronic parts 20 are conveyed at a time and are to be stored in the carrier tape 21 at the same time, the electronic part in the intermediate part thereof is required. When the component 20 is defective in the previous process and is in a toothless state, the electronic component 20 cannot be housed without a toothless portion only by controlling the feeding operation of the carrier tape 21. Only transportation and storage were possible, and the productivity was poor.

The arrangement pitch between the two electronic components 20 cannot be stored in the carrier tape 21 unless the pitch is the same as the storage hole 22 of the carrier tape 21. There is a problem that the adjustment must be performed or a pitch correction portion must be provided in the middle of the adjustment.

An object of the present invention is to solve such a conventional problem and to eliminate electronic parts conveyed at a pitch different from the accommodating hole pitch of the carrier tape in units of three or more at a time without missing portions. It is an object of the present invention to provide a highly productive electronic component taping device that can be stored in a storage hole of a carrier tape.
