Abstract

PURPOSE:To make the speed of a TAB tape processing further higher than conventional ones, by shortening the loss times required for replacement of a TAB reel and a spacer reel. CONSTITUTION:On the tape supply side of a TAB tape processor, a TAB tape 2 is transferred from a TAB reel 1 in a position (A) to the TAB tape take-up side opposed to this position A, and concurrently, a spacer is taken up by a spacer reel 3. Then, when the TAB reel 1 is empty, the TAB reel 1 at a position (B) is moved to the position A. The front end of a leader tape connected with the front end of the TAB tape 2 moved to the position A and the back end of a leader tape connected with the back end of the preceding TAB tape 2 are connected with each other, and thereby, the replacement of the TAB tape 2 is performed. Still, on the tape take-up side, almost the same replacement of the TAB tape 2 is performed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reel exchange method for a TAB tape supply side or take-up side.

[0002]

2. Description of the Related Art Conventionally, in TAB tape processing, for example, as disclosed in Japanese Patent Laid-Open No. 6-45405, a TAB tape supplied from one side of the TAB tape is wound on the other side, Predetermined processing such as potting is performed between the winding sides.

At that time, on the supply side, the TAB tape is sent (unwound) from the TAB reel, the spacer tape is wound on the spacer reel, and the TAB reel is wound on the winding side opposite to the supply side. And TA
While winding the B tape, the spacer tape is sent out (unwound) from the spacer reel.

Then, from the TAB reel on the supply side, TA
When a predetermined length of B tape is sent (unrolled),
The tape is cut at predetermined positions on the supply side and the take-up side of the TAB tape, and the TAB reel and the spacer reel on the supply side are removed from the reel shafts mounted on the apparatus frame so as to be driven and rotated, The TAB reel and the spacer reel are mounted on each reel shaft, and the TAB reel and the spacer reel on the winding side are also replaced in the same manner.

That is, TA from the TAB reel on the supply side
TA of the specified length of B tape is sent (unrolled)
Each time the B reel is in a so-called empty reel state (however, the rear end of the TAB tape is locked to the reel) and the TAB reel on the take-up side is fully wound, the supply side and the take-up side respectively. In, the TAB reel and the spacer reel are exchanged.

[0006]

However, such reel exchange has been accompanied by the recent increase in the speed of TAB tape processing, and the TAB reels on the TAB tape supply side and the take-up side, respectively. Also, it becomes necessary to frequently replace the pacer reel, and therefore, the loss time at the time of this replacement cannot be ignored, and improvement in this point has been urgently needed.

In view of the above-mentioned problems, the present invention has made intensive studies to solve the problems, and as a result, a pair of TAB reels and spacer reels are sequentially transferred to a T-type by a slide table method.
It has been found that the loss time at the time of reel replacement can be shortened by moving the AB tape to the feeding or winding position.

[0008]

[Means for Solving the Problems] That is, a first reel changing method on the supply side or take-up side of a TAB tape according to the present invention is to mount a TAB reel shaft and a spacer reel shaft on a slide table, and , The TAB
A plurality of TAB reels are mounted in multiple stages on the reel shaft, and a plurality of spacer reels are mounted in multiple stages on the spacer reel shaft, and by the movement control of the slide table, the pair of TAB reels and spacer reels in the preceding stage is removed. It is characterized in that a pair of both reels in the subsequent stage is sequentially moved to a TAB tape feeding or winding position to perform reel exchange.

In a second reel replacing method on the TAB tape supply side or take-up side according to the present invention, a TAB reel shaft and a spacer reel shaft are mounted on a slide table, and the TAB reel shaft is mounted on the TAB reel shaft. , Multiple T
The AB reels are mounted in multiple stages, and a plurality of spacer reels are mounted in multiple stages on the spacer reel shaft, and the TA of the rear stage is controlled by the movement control of the slide table.
It is characterized in that the pair of both reels in the preceding stage is sequentially moved from the pair of the B reel and the spacer reel to the feeding or winding position of the TAB tape to perform the reel exchange.

In the reel exchange method on the supply side or the winding side of the TAB tape, the feeding or winding of the TAB tape is completed for all pairs of TAB reels and spacer reels. After that, it is preferable to remove them from both shafts, and then to mount both reels to which the TAB tape is to be fed or wound, on both shafts.

[0011]

In FIG. 1 and FIG. 2 which is a left side view of this figure, a reel exchange mode on the supply side of the TAB tape is shown. That is, in both figures, the TAB reel 1
The TAB tape 2 is sent out from the spacer tape 4 and the spacer tape 4 is wound up by the spacer reel 3. At that time, the drive rollers 7 and 8 mounted on the arms 5 and 6 so as to be driven and rotated are pressed against the reels 1 and 3 by the swing control of the arms 5 and 6, and thus the reels 1 and , 3 are rotated in the directions of the arrows in the figure.

The TAB reel 1 and the spacer reel 3 are composed of a TAB reel shaft 9 and a spacer reel shaft 10.
In addition, the TAB reels 1 to T are mounted in a constant pitch in multiple stages (for example, A to D stages).
The AB tape 2 is sent out, and the spacer tape 4 is wound up by the spacer reel 3 in the same stage.

Then, a predetermined length of the TAB tape 2 is sent from the TAB reel 1 so that the TAB reel 1 is in a so-called empty reel state (however, the leader tape connected to the rear end of the TAB tape 2 has a predetermined number of times, It is wound around the TAB reel 1.), the drive roller 7, which is pressed against the TAB reel 1 and the spacer reel 3,
The rotation of 8 is stopped and the pressure contact is released, so that
The rotation of both reels 1 and 3 is stopped.

Next, the leader tape is positioned and cut in a predetermined manner, and then the slid table 11 on which the TAB reel shaft 9 and the spacer reel shaft 10 are mounted is moved to move the TAB reel 1 at the B stage position. And the spacer reel 3 is moved to the position A, that is, the TAB tape feeding position.

Hereinafter, the leading end of the leader tape connected to the leading end of the TAB tape 2 wound around the TAB reel 1 moved from the B stage position to the A stage position and the trailing end of the preceding TAB tape 2 Is connected to the rear end of the leader tape connected to, and then the drive rollers 7 and 8 are pressed and rotated to the reels 1 and 3 which have been moved from the position of the B stage to the position of the A stage. As a result, following the feeding of the leader tape portion, the TAB tape 2 is fed and the spacer tape 4 is wound up.

In this way, the pair of reels 1 and 3 in the subsequent stage are sequentially moved from the pair of the TAB reel 1 and the spacer reel 3 in the preceding stage (A stage) to the TAB tape feeding position (the A stage position). Then, the TAB tapes 2 can be sent one after another, so that the loss time at the time of reel exchange on the supply side of the TAB tapes can be shortened.

Although the reel exchange mode on the supply side of the TAB tape has been described above, the winding side on the side opposite to the supply side (see FIG. 4, which is a front view), can also be used.
Reel exchange can be performed in almost the same manner.

The TAB reel 1 and the spacer reel 3 are provided with the same diameter and are located at a portion A (hereinafter referred to as a tape feeding position) shown in FIG. 2 and the TAB reel 1 is , Is rotated in the direction of the arrow shown in the drawing by the drive roller 7 pressed against it, and the spacer reel 3 is also rotated at the same speed as the drive roller 7 in the direction of the arrow shown in the drawing by the drive roller 8 pressed against this. .

Therefore, the tape can be continuously or intermittently fed from the tape supply side to the tape take-up side of the TAB tape processing apparatus as needed, but at this time, the drive rollers 7 and 8 are mounted. The swing of the arms 5 and 6 is controlled. That is, since the arms 5 and 6 are attached to the arm shafts 15 and 16 which are attached to the device frame 13 so as to be able to rotate forward and backward by a predetermined angle by a drive device (not shown), the arms 5 and 6 are shaken in a predetermined manner. The driving rollers 7 and 8 can be pressed against or separated from the reels 1 and 3 by the dynamic control.

The drive rollers 7 and 8 are composed of arms 5 and 6, respectively.
It is mounted so that its rotation can be controlled by a drive device (not shown) mounted on the. The TAB tape 2 has leader tapes of a fixed length connected to both ends thereof, one end of the leader tape being wound around the TAB reel 1 on the tape supply side a predetermined number of times, and the other leader tape. Is wound around the TAB reel 1 on the tape winding side (see FIG. 4) opposite to the tape supply side a predetermined number of times.

In addition, the TAB reel 1 is mounted on the TAB reel shaft 9, and the spacer reel 3 is
Although mounted on the spacer reel shaft 10, in FIG. 3 which is a vertical sectional view, a mounting manner of both reels 1 and 3 on both shafts 9 and 10 is enlarged and shown.

In FIG. 1, the TAB reel 1 (or the spacer reel 3) is mounted on the TAB reel shaft 9 (or the spacer reel shaft 10) via a bearing 17, a bearing receiver 18 and a nut 19 so as to be rotatable. A ring-shaped coil spring 22 that is fitted in the reel receiver 20 and is inserted in the groove 21 of the reel receiver 20.
It has been prevented from coming off.

The TAB reels 1 (or spacer reels 3) are mounted at equal pitches in the longitudinal axis direction of the TAB reel shaft 9 (or spacer reel shaft 10), and both shafts 9 and 10 are mounted. Is attached to the slide table 11 so as to be attachable to and detachable from the slide table 11.

The slide table 11 is guided by a pair of guide rails 31 (see FIG. 1) mounted on the apparatus frame 13 by means such as an actuator (not shown) and is shown in FIG. It is mounted so that it can move in the direction of the arrow, and a TAB cueing arm 23 is mounted on it, and four tapes are attached to this cueing arm 23 at a pitch equal to the mounting pitch of the TAB reel 1. A head 24 is attached. Further, the cutter device 25 and the splice device 26 are mounted on the device frame 13, and the details thereof will be described later.

As shown in FIG. 2, the tape feed of a predetermined length is performed through the pair of the TAB reel 1 and the spacer reel 3 at the preceding stage, which is located at the tape feed position A by the movement control of the slide table 11. After that, when the TAB reel 1 is in a so-called empty reel state (however, the leader tape connected to the rear end of the TAB tape is wound around the TAB reel 1 a predetermined number of times).
The pressure contact of the drive rollers 7 and 8 to the B reel 1 and the spacer reel 3 is released, and the rotation of both reels 1 and 3 is stopped, that is, a positioning index (for example, a through hole) provided at a predetermined position of the leader tape. Is detected by a phototube device (not shown), the rotation of the drive rollers 7 and 8 is stopped based on the signal, and the arms 5 and 6 are swing-controlled so as to separate them from the reels 1 and 3. To be done.

Subsequently, as will be described later, the leader tape is positioned and cut in a predetermined manner, and thereafter, the slide table 11 on which the TAB reel shaft 9 and the spacer reel shaft 10 are mounted is moved to move to the B stage position. TAB
The reel 1 and the spacer reel 3 are paired at the position A,
That is, it is moved to the delivery position of the TAB tape 2.

Then, subsequently, a leader tape connected to the leading end of the TAB tape 1 wound around the TAB reel 1 moved to the position A and a trailing end of the preceding TAB tape 2 are connected. When the leader tapes are connected to each other as will be described later, the drive rollers 7 and 8 are pressed against the reels 1 and 3 and rotated, so that the TA tape is continuously fed after the leader tape portion is fed.
The B tape 2 is sent out and the spacer tape 4 is wound up.

Thereafter, through the same steps, the TA of the next C stage
The tape can be sent out through the pair of the B reel 1 and the spacer reel 3, and subsequently, the tape can be sent out through the pair of the TAB reel 1 and the spacer reel 3 in the D stage. . Therefore, the loss time at the time of exchanging the reel on the tape supply side of the TAB tape processing device can be shortened, and the TAB tape processing can be speeded up.

In the reel exchange, when the arms 5 and 6 are controlled to swing so as to separate the drive rollers 7 and 8 from the reels 1 and 3, the leader tape is positioned and cut. This is done via the cutter device 25 and the splice device 26.

That is, when the tape feeding is stopped, the splicing device 26 is guided by the pair of rails 27 and moved toward the cutter device 25, so that the splicing device 26 is positioned at 2a shown in FIG. The leader tape is pressed so as to approach the cutter device 25. Then, in this state, the splice device 26
The pin plate 28 is inserted into the tape feed hole penetrating the end portion in the width direction of the leader tape, and is moved slightly upward (for example, about 5 mm).

Therefore, the leader tape is positioned in a predetermined manner, and then the leader tape is cut by the cutter device 25. This cutting is performed at a position several mm above the position where the pin plate 28 locks the leader tape. Then, the pair of the TAB reel 1 and the spacer reel 3 in the B stage is moved to the position A, that is, the tape feeding position.

The TAB reel 1 is attached to the TAB reel shaft 9.
When mounting, the tip of the leader tape connected to the tip of the TAB tape 1 wound on the reel is attached to the double-sided adhesive tape attached to the tape adhering head 24, and as it is. Then, the tape is moved to the delivery position A of the TAB tape.

Next, after the pin plate 28 is moved further upward, it is moved to the cutter device 25 side, and therefore the preceding TAB tape 2 (TAB tape transferred to the tape winding side via the guide roller 14). Rear end of leader tape connected to the rear end (upper end in Fig. 1)
Is adhered to the double-sided adhesive tape adhered to the tape adhering head 24 (hereinafter, this portion is referred to as a connecting portion).

Subsequently, the tape adhering device 29 of the splicing device 26 is moved toward the tape adhering head 24,
The adhesive tape attached to the protrusion of the tape wheel 30 is attached to the connecting portion. This allows the preceding T
The leader tape connected to the rear end of the AB tape 2 and the leader tape connected to the front end of the TAB tape 2 to be fed next are connected.

After the splicing device 26 is returned to its original position, the tape wheel 30 is rotated 90 degrees in the direction of the arrow in the figure, and the arms 5 and 6 are swing-controlled to drive the reels 1 and 3. The rollers 7 and 8 are pressed and rotated. In this way, the reels are exchanged one after another and the TAB
From the tape supply side of the tape processing device to the tape winding side (Fig.
Tape). At the point in time when the TAB tape 2 has been sent out for a certain length, TA
The B tape 2 is located at 2a.

On the other hand, correspondingly, as shown in FIG. 4, the TAB reel 1 winds the tape on the tape winding side of the TAB tape processing apparatus.
At that time, the spacer tape 4 is sent out (unwound) from the spacer reel 3, so that the spacer tape 4 is superposed on the TAB tape 2 and wound on the TAB reel 1.

The first winding of the TAB tape 2 and the spacer tape 4 is A shown in FIG.
At the tape winding position corresponding to the tape feeding position.
The reel 1 and the spacer reel 3 can be sequentially moved from the pair of reels 1 and 3 to the tape winding position by the movement control of the slide table 11 so that the reels can be exchanged one after another.

When the arms 5 and 6 are controlled to swing so as to separate the drive rollers 7 and 8 from the reels 1 and 3 in the reel exchange, the leader tape is positioned and cut. This is done via the cutter device 25, the splice device 26, etc., similar to that on the tape supply side described above. At that time, the connection between the spacer tapes 4 transferred from the tape supply side is performed in a state of being positioned between the cutter device 25 and the TAB reel 1. The TAB tape 2 is located at the position 2b when the TAB tape 2 is wound up to a certain length.

As described above, on the tape supply side and the winding side of the TAB tape processing device, the TAB reel 1 of the preceding stage (A stage)
Also, an example in which the pair of both reels in the subsequent stage is sequentially moved from the pair of spacer reels 3 to the TAB tape 2 feeding or winding position to perform reel replacement has been described. Alternatively, the reels may be exchanged by sequentially moving the reels in the rear stage (D stage) from the pair of the TAB reels 1 and the spacer reels 3 in the front stage to the TAB tape 2 feeding or winding position. In any case, the pair of the TAB reel 1 and the spacer reel 3 is not limited to being mounted in four stages A to D, and can be mounted in any number of stages. When the reels are exchanged by sequentially moving the reels in the rear stage (D stage) from the pair of TAB reels 1 and the spacer reels 3 to the reels in the front stage, the reels are moved to the TAB tape 2 feeding or winding position. Initially, the former stage (A
(Stage) TAB reel 1 and spacer reel 3 pair,
The position of the TAB reel 1 and the spacer reel 3 at the latter stage (D stage) is located at the position indicated by the chain line in FIG. 2 and is located at the feeding or winding position of the TAB tape 2.

In addition, after the feeding or winding of the TAB tape 2 is completed with respect to the pairs of the TAB reel 1 and the spacer reel 3 in all the stages, they are removed from the TAB reel 9 and the spacer reel shaft 10, and subsequently, It is preferable to replace both reels 1 and 3 for feeding or winding the TAB tape so that they can be mounted on both shafts 9 and 10. In that case, both reels 1 and 3 can be removed by both shafts. After removing the nuts 19 from the shafts 9 and 10, a reel unit composed of the bearing 17, the bearing receiver 18, the reel receiver 20, the TAB reel 1 (or the spacer reel 3), and the like is set on both shafts 9 and 10. The reel unit is attached to both shafts 9 and After fitted into 0, it is carried out as occupies dressed threaded nut 19.

Besides this, for example, both shafts 9 and 10 can be attached to and detached from the slide table 11 with the reel unit still attached to the TAB reel shaft 9 and the spacer reel shaft 10. You may exchange it. However, this replacement method is more difficult than the former replacement method (reel unit-based replacement method) in that heavy objects must be handled. Therefore, the former replacement method is preferable.

In any method, such reel exchange is performed in a state where the slide table 11 is moved to an appropriate position on the left side in FIG.
Also, means for controlling the movement of the slide table 11, TA
Means for rotating the B reel 1 and the spacer reel 3,
The means for positioning and cutting the leader tape, the means for joining the leader tapes, and the like are not limited to the means described in the embodiments, and may be provided for other means.
