[0005]

However, in the transport device shown in FIG. 4, the number of times the transport pin is replaced with the transport hole increases, and it takes time to transport the tape.
There is a high possibility that the replacement of the transport pin will fail. Further, in the carrying device shown in FIG. 5, the carrying pin is pulled out from the feed hole after moving the carrying pin a plurality of times at predetermined intervals, so that when the carrying pin reaches the end point of the movement, The distance between the transport pin and the inspection position increases. Therefore, as shown by the arrow e in FIG. 5B, the tape is likely to be displaced in the width direction, and the electronic component at the inspection position may be displaced, so that the characteristics cannot be inspected. Further, when the transport pin is pulled out from the feed hole, the transport pin may not be pulled out properly, and the tape may be pulled by the transport pin and damaged.

Therefore, the main object of the present invention is to reduce the number of times the transfer pins are replaced, prevent displacement of strip-shaped or strip-shaped workpieces, and eliminate mistakes in pulling out the transfer pins. It is an object of the present invention to provide a work positioning and transporting device.

BEST MODE FOR CARRYING OUT THE INVENTION A positioning / conveying device for conveying a tape supporting a plurality of electronic components and inspecting the characteristics of the electronic components at a predetermined position will be described as an example of a workpiece positioning / conveying device. The positioning and transporting device 10 is used to transport a pair of tapes 14 supporting a plurality of electronic components 12, as shown in FIGS.
The tape 14 is made of paper, resin, metal or the like, and is formed in a strip shape or a strip shape, and the feed holes 16 at equal intervals are formed in one row.

A plurality of electronic components 12 are supported between the pair of tapes 14 at equal intervals. As the electronic component 12,
For example, it is conceivable that the inductor and the capacitor are built in, and the lead wire extending from the opposite end is the tape 1
Supported by 4. Note that in FIG. 1B, the electronic component 12
Although two lead wires extend from both ends of each, the number of lead wires is not particularly limited.

Further, the positioning transfer device 10 includes a plurality of transfer pins 18. The carrying pin 18 is, for example, 1
The pair of tapes 14 are supported by the support member 20 at intervals corresponding to the feed holes 16. The transport pins 18 are arranged in two rows so as to fit the pair of tapes 14. The transport pins 18 in each row are arranged at the same intervals as the feed holes 16 of each tape 14. Further, for example, a plate-shaped stripper 22 is formed between the transport pins 18 arranged in two rows.

As shown in FIG. 2, the electronic component 12 is inspected for its characteristics and the like at a predetermined inspection position 24.
Here, in order to convey each electronic component 12 to the inspection position 24 one by one, as shown by the arrow a in FIGS. Inserted in. At this time, the transport pin 18 on one end side is inserted into the feed hole 16 in a portion near the inspection position 24,
The other transport pins 18 are inserted into the continuous feed holes 16. The position where the transport pin 18 is first inserted into the feed hole 16 of the tape 14 is the starting point of the movement range of the transport pin 18.

In this state, the supporting member 20 moves along the tape 14 and the tape 14 is conveyed. At this time, the support member 20 is moved in the direction starting from the transport pin 18 inserted into the feed hole 16 near the inspection position 24. As a result, the electronic component 12 is also transported, but the support member 20 is stopped when the electronic component 12 is transported by the distance between the adjacent electronic components 12. Therefore, the inspection position 2
The electronic component 12 adjacent to the electronic component 12 already inspected in 4 is conveyed to the inspection position 24 and stopped. Here, after the electronic component 12 is inspected, the support member 20 again moves by the distance between the adjacent electronic components 12 and is stopped. Such an operation is repeated a plurality of times as shown by an arrow b in FIG. 2B, whereby the electronic components 12 are transported to the inspection position 24 one by one, and the characteristics are inspected.

In this way, when the electronic components 12 are transported to the inspection position 24 one by one and reach the end point of the moving range of the transport pin 18, as shown by an arrow c in FIG. 2B,
The support member 20 rises, and the transport pin 18 is pulled out from the feed hole 16 of the tape 14. At this time, FIG. 3 (A)
As shown in (B), the stripper 22 descends, the tape 14 is pressed, and the transport pin 18 and the tape 14 are separated. When the transport pin 18 is pulled out from the feed hole 16, the support member 20 moves to the position that is the starting point of the movement range of the transport pin 18, as shown by the arrow d in FIG. That is, the leading transport pin 18 is located at the inspection position 2
The support member 20 moves to the position of the four parts. At this position, as shown by the arrow a in FIG.
Is lowered, the transport pin 18 is again inserted into the feed hole 16 of the tape 14, and the tape 14 is transported. By repeating such an operation, the tape 14 is conveyed by a predetermined amount.

In this positioning and transporting device 10, with the transport pin 18 inserted in the feed hole 16 of the tape 14,
By repeating the operation of moving at predetermined intervals, it is possible to move the plurality of electronic components 12 to the inspection position 24 without replacing the transport pin 18. Since the transport pins 18 are replaced after the characteristics of the plurality of electronic components 12 are inspected, the number of replacements is small, the transport speed of the tape 14 can be increased, and the transport pins can be replaced. The chance of failure in replacement is also reduced.

Further, the plurality of transport pins 18 are attached to the tape 14
Since it is inserted into the feed hole 16 of the
Even if is moved, another transport pin 18 is inserted into the feed hole 16 of the tape 14 at the inspection position 24. Therefore, the tape 14 is not displaced at the inspection position 24, and the electronic component 12 can be stopped at a predetermined position. Therefore, the characteristics of the electronic component 12 can be reliably inspected.

Further, since the stripper 22 is provided, it is possible to prevent the tape 14 from being pulled up by the transport pin 18 when the transport pin 18 is pulled out from the feed hole 16, and the transport pin 18 is surely carried out. And the tape 14 can be separated. The stripper 22 need not be provided if the transport pin 18 can be smoothly pulled out from the tape 14.

In the above example, in order to inspect the characteristics of the electronic component 12 at the inspection position 24, the tape 14 is conveyed by the distance between the adjacent electronic components. However, depending on the purpose,
The transport distance can be changed arbitrarily. Further, the tapes 14 may be ones in which the electronic components 12 are supported by one tape 14 instead of one pair, and in this case, the transport pins 18 are arranged in only one row. Of course, a strip-shaped or strip-shaped work can be conveyed by a predetermined amount and positioned even if it does not support electronic components.

[0020]

According to the present invention, the number of times the transfer pins are replaced can be reduced, the work can be transferred in a short time, and the possibility of failure in the transfer pin replacement is reduced. be able to. Further, since the plurality of transport pins are inserted into the feed holes, it is possible to prevent displacement of the work in a long range. Further, by using the stripper, the transport pin can be reliably separated from the work.
