DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape collecting device of a mounting machine for processing a used tape after supplying a component in a mounting machine adapted to supply a chip component using a tape as a carrier. .

[0002]

2. Description of the Related Art Conventionally, a mounting machine for mounting chip components on a printed circuit board is equipped with a tape feeder for supplying components, whereby a large number of chip components can be moved one after another to a predetermined position. There is known a device in which a chip component is taken out of a tape feeder at the predetermined position by a suction head.

In the above-mentioned tape feeder, for example, a tape containing a large number of chip components is wound around a reel in advance at regular intervals and includes a tape body and a cover tape, and this reel is attached to the rear of the feeder. The tape led out of the reel is guided to the component take-out part in front of the feeder, where the cover tape is peeled off from the tape body and chip components can be taken out. Chip parts are successively taken out while the tape is fed out.

[0004] With respect to the tape main body and the cover tape (used tape) after the parts are supplied, the tape main body is guided under the tape feeder or the like and collected in a predetermined storage box or the like. The reel is wound on a reel provided in the feeder, and when any of the reels reaches a predetermined amount, the reel is discarded by an operator.

[0005]

By the way, in the above-mentioned apparatus, as much as possible of the used tape sent out from the tape feeder is collected, whereby the work efficiency can be improved by reducing the disposal work by the operator. Is more preferred.

However, in the above-mentioned conventional apparatus which is configured to wind up the cover tape with a collecting reel provided in a feeder, since the collecting capacity is small due to its structure, the operator can dispose of the cover tape in a relatively short time. Is needed.
In addition, it is conceivable to increase the collection capacity by increasing the amount of tape wound by the collection reel, but in reality, a large driving means for winding a large amount of cover tape, and This is not always advantageous because the feeder is required to have a large rigidity capable of supporting the feeder, which leads to an increase in the size of the feeder.

Further, it is conceivable that the used tape is directly guided to a storage box or the like to be collected. However, if a long connected used tape is stored while being bent, it becomes easy to be bulky. If it does not fit in the storage box,
In some cases, the tape may be bent or the like may be clogged in the middle of the passage, causing a failure.

Further, if the used tape body and the cover tape are individually collected, the space for installing a storage box or the like for collection is increased, and inefficiency in collection and disposal operations is liable to be caused.

Further, it is necessary to consider the workability of the disposal operation such that the collected used tape can be easily and safely disposed of.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a tape for a mounting machine capable of efficiently collecting used tapes in a small space efficiently and reducing disposal work. It is intended to provide a recovery device.

In the embodiment, the dust box 31 is a box body having an upper opening made of, for example, a resin material. Although not shown, the dust box 31 is provided via a door provided on a side surface (right side in FIG. 2) of the case 30. The case 30 can be taken out of the case 30.

An example of the control of the tape collecting device of the mounting machine configured as described above will be described with reference to the flowchart of FIG.

In step S1, a mounting operation is performed.
More specifically, this mounting operation is performed first by using the head unit 5.
Is moved in the X-axis and Y-axis directions, the nozzle member 16 is positioned at the supply position of the chip component to be mounted, that is, at the component take-out portion 22 of the predetermined tape feeder 4a in the component supply device 4, and the nozzle member 16 20
And the tape component is picked up, and the feeding mechanism 23 of the tape feeder 4a is operated to feed the tape 20. When the suction of the chip components by the head unit 5 is completed, the head unit 5 is moved above the substrate 3 on which the head unit 5 is positioned, the nozzle member 16 is lowered, and the negative pressure for suction is shut off at a predetermined timing. As a result, the chip component is mounted on the substrate 3.

When the mounting of the chip components on the substrate 3 is completed in step S1, a counter (counter value N) (not shown) is counted up in step S2, and the counter value N is set in advance in step S3. It is determined whether the set value has been reached.

At this time, when it is determined that the counter value N has reached the set value (YES in step S3), the cutting mechanism 33 of the tape collecting device 6 is operated, whereby the respective tape feeders 4a are turned off. The used tapes introduced into the tape collecting device 6 are cut at once and stored in the dust box 31. After the cutting mechanism 33 is operated, the counter is reset (step S).
4, S5), and proceeds to step S6.

If it is determined in step S3 that the count value has not reached the set value, the process proceeds to step S6.

In step S6, it is determined whether or not the mounting of the predetermined number of chip components on the substrate 3 has been completed. If the mounting has not been completed (NO in step S6), the process proceeds to step S1 to perform the mounting operation. Repeated.

On the other hand, if the mounting of the predetermined number of chip components on the board 3 has been completed (YES in step S6), the process proceeds to step S7, where it is determined whether or not there is an operation command to the cutting mechanism 33. Judgment is made. This is a dust box 31 for disposal of used tape.
When the mounting operation is completed, the cutting mechanism 33 can be operated as required. When the mounting operation is completed, this is notified, and an operator is provided on the mounting machine. When the operation switch or the like is operated, the cutting mechanism 33
Is activated. That is, step S7
In, it is determined whether or not an operation command has been issued by operating an operation switch or the like. If an operation command has been issued (YES in step S5), the process proceeds to step S8, where the cutting mechanism 33 is operated and Then, in step S9, the counter is reset and the flowchart ends.

On the other hand, if there is no operation command in step S7 (NO in step S7), the cutting mechanism 3
This flowchart is ended without the operation of the flowchart 3.

In the mounting machine equipped with the tape collecting device configured as described above, the used tape sent out from each tape feeder 4a during the mounting operation is preferably used.
In addition, it is possible to efficiently collect and reduce the work required for disposal.

That is, in the above mounting machine, the used tape sent from each tape feeder 4a is housed in the dust box 31 while being finely cut by the cutting mechanism 33 while being guided into the inside of the tape collecting device 6. Therefore, the used tape collected in the dust box 31 does not become bulky. Therefore, even when the capacity of the dust box cannot be sufficiently ensured due to the design, the used capacity can be efficiently used to efficiently store the used tape. Therefore, it is possible to reduce the number of times of disposal of the collected used tape, thereby reducing the number of disposal operations.

Further, in such a method in which the used tape is collected in the dust box 31 while being finely cut, the used tape is rarely entangled at the entrance to the dust box 31 or the like. Compared with a conventional apparatus that guides and collects used tapes in a dust box, it is possible to preferably collect used tapes without causing tape clogging or the like.

In particular, in the tape collecting device 6,
A cutter 35 and an elastic body 36 are extended corresponding to each tape feeder 4a, and when the cutting mechanism 33 is operated, each used tape sent from each tape feeder 4a is simultaneously cut at a time. So
With a very simple structure, the used tape sent from each tape feeder 4a can be suitably cut.

In the above mounting machine, the tape main body 20a and the cover tape 20b sent from each tape feeder 4a are integrally guided into the tape collecting device 6 and cut and collectively stored in the dust box 31. As a result, it is not necessary to separately provide the cutting mechanism 33 for the tape body 20a and the cover tape 20b, so that the structure is simplified and the tape body 20a
And the cover tape 20b can be collected together and discarded. Therefore, the tape body 20a and the cover tape 2
Compared with the conventional apparatus that separately collects 0b, the disposal of used tape is reduced. Particularly, in the above-described embodiment, the used tape sent from each tape feeder 4a is collected by being guided to the tape collecting device 6 arranged on the side of the base 1 of the mounting machine. It is extremely easy to dispose of used tapes, and since the work can be done on the side of the mounting machine, there is no danger of workers coming into contact with the movable parts of the mounting machine, etc. Work can be done.

The above embodiment is an embodiment showing the tape collecting apparatus of the present invention, and the specific configuration is not limited to the above embodiment, and may be changed as appropriate without departing from the gist of the present invention. It is possible.

For example, the tape collection device 6 of the above embodiment
Is disposed on the side of the base 1 of the mounting machine body, and the case 30
Is mounted so as to be able to move independently of the mounting machine main body by means of casters or the like provided in the mounting machine. However, it is not always necessary to adopt such a configuration, and the tape feeder 4a is mounted on the base 1 of the mounting machine. In the case of a mounting machine capable of securing a space for mounting the tape collecting device 6 below or the like, the tape collecting device 6 may be incorporated in the mounting machine main body.

In the tape collecting device 6 of the above embodiment, the shapes and materials of the cutter 35 and the elastic body 36 of the cutting mechanism 33 are not described in detail, but are appropriately set so that the used tape can be suitably cut. What is necessary is just to form it. For example, the cutter 35 may simply have a straight blade, but each of the tape feeders 4
The part corresponding to each used tape sent from a.
As shown in FIG. 5, if the cutting edge is formed in an irregular shape such as a V-shape, the tape can be more reliably cut. The elastic body 36 may also have a cushioning property such that the cutting edge of the cutter 35 is appropriately pressed when the cutting mechanism 33 is operated. For example, the elastic body 36 may be formed of a urethane resin or a rubber material. preferable.

The specific configuration of the mounting machine to which the tape collecting device of the present invention is applied is not limited to the present invention, but can be changed as appropriate.

[0054]

As described above, according to the present invention, there is provided a guiding means for integrally guiding the tape body and the cover tape after the parts are supplied, and the guiding means integrally cuts the tape body and the cover tape. A cutting mechanism is provided to guide the tape body and the cover tape peeled off at the component take-out part integrally by a guiding means so as to discard them while cutting them finely by the cutting mechanism. Therefore, the tape main body and the cover tape after the component supply can be efficiently collected by effectively utilizing the small space.

Further, the above-mentioned cutting mechanism is constituted by a tape cutting cutter and an elastic member arranged to face the same, and the cutter is moved forward and backward by a driving mechanism. And the cover tape can be cut.

In this case, by forming the cutter and the elastic member of the cutting mechanism so as to extend in the direction in which the tape feeders are juxtaposed, all the tape bodies and cover tapes sent from the juxtaposed tape feeders can be removed. It can be discarded while being cut at once.

By providing a storage member for storing the cut tape body and cover tape below the cutting mechanism, the tape body and cover tape can be suitably collected and discarded.
