2. Description of the Related Art With the development of the electronics industry,
The demand for printed wiring boards on which electronic components such as C (integrated circuits) and LSIs (large-scale integrated circuits) are mounted has been rapidly increasing, but there has been a demand for smaller, lighter, and more sophisticated electronic devices. Recently, TAB has been used as a mounting method for these electronic components.
A mounting method using a film carrier tape for mounting electronic components such as a tape, a T-BGA tape, and an ASIC tape has been adopted. In particular, the importance thereof is increasing in the electronic industry using a liquid crystal display device (LCD), such as a personal computer, which requires high definition, thinness, and a narrow frame area of a liquid crystal screen.

Further, recently, among film carrier tapes, as shown in FIG.
A hole 302 is formed in the film carrier tape 300 in place of the outer lead called “Array”, and the hole 30
2, a film carrier tape not provided with a device hole for connecting an IC 304 or the like with a solder ball 306 via an IC 2 called a CSP (Chip Size Package).
The size of C and the size of the package of the film carrier tape are the same, and a film carrier tape whose connection method is mainly the same as that of BGA is also used.

In such a film carrier tape for mounting electronic components, for example, as shown in FIG. 5, a TAB tape 200 has a plurality of transporting tapes at both ends in the width direction, each of which is continuously provided in the longitudinal direction. Sprocket holes 202, 20
2 are provided side by side, and a device hole 204 for mounting a device such as an IC is formed at a substantially central portion between the sprocket holes 202. Then, an inner lead 206 and an outer lead 208 of the device hole 204 are formed.

Further, after performing such an image inspection, an appearance inspection for defective plating, dirt, foreign matter and the like, which are defects of the film carrier tape for mounting electronic components, is performed by using a reflected light or transmitted light with a stereoscopic microscope. And is implemented visually.

[0007]

SUMMARY OF THE INVENTION
Conventionally, an inspection apparatus as shown in FIG. 7 has been used when performing an appearance inspection. That is, in the conventional inspection apparatus 400, the film carrier tape T for mounting electronic components wound on the reel 402
Is supplied to the inspection unit 408 provided with a stereomicroscope or the like via a delivery dancer roller (step roller) 406 for applying tension to the film carrier tape T for mounting electronic components. ing.

[0008] The film carrier tape T for mounting electronic components is conveyed to the inspection unit 408 by a drive gear 410 composed of a sprocket gear and a pressing roller 412, and is placed below the inspection device 414 of the inspection unit 408. When a predetermined inspection site of the film carrier tape T is located, the conveyance is stopped (pitch-fed).
Then, the back tension is applied to the film carrier tape T for mounting electronic components by the back tension gear 416 composed of a sprocket gear and the pressing roller 418, the positioning is performed, and the inspection is performed.

After the inspection, the film carrier tape T for mounting electronic components is passed through a take-up dancer roller 420 to which a tension is applied, and then the reel 4 of the take-up device is used.
26. In such a conventional inspection device 400, the delivery dancer roller 40
8 and the take-up dancer roller 420 are respectively shown in FIG.
As shown in the figure, a certain tension is applied to the film carrier tape T for mounting electronic components by two position sensors 422 and 424 vertically arranged for detecting the position of the base end of the support shaft of the dancer roller. It is controlled so that.

That is, for example, as shown in FIG.
When the upper position sensor 422a detects that the position of the base end 409 of the support shaft 407 of the feed-out dancer roller 406 is at the upper position, that is, when the feed-out dancer roller 406 is at the lower position, Stop feeding. Conversely, when the lower position sensor 422b detects that the position of the base end 409 of the support shaft 407 of the feed-out dancer roller 406 is at the lower position, that is, when the feed-out dancer roller 406
Is in the upper position, the feeding of the feeding device 404 is started. Thus, control is performed so that a certain tension is applied to the film carrier tape T for mounting electronic components. Note that such control is similarly performed for the take-up dancer roller 420.

However, in the method in which the dancer roller is moved up and down by turning on and off the two sensors, and the tension is applied to the film carrier tape T for mounting electronic components, the tension is applied by the weight of the dancer roll. Therefore, when the transport is stopped when a predetermined inspection portion of the film carrier tape T for mounting electronic components is positioned below the inspection device 414 of the inspection unit 408, or when the feed-out dancer roller 406 is in the upper position or the lower position. When the stop is made, the dancer roller 406 for sending out swings up and down as shown by the arrow K in FIG.

[0012] Therefore, the swing of the sending-out dancer roller 406 also moves the position of the electronic component mounting film carrier tape. The position of T shifts, which affects the accuracy of the stop position of the film carrier tape T for mounting electronic components, so that an accurate stop position cannot be obtained, and the reliability of the inspection itself also decreases. Note that such a problem occurs not only on the feed-out dancer roller 406 side but also on the take-up dancer roller 420 side.

In view of the above situation, the present invention always applies a constant tension to a tape-like material such as a film carrier tape for mounting electronic parts. When performing processing such as screen printing, electrical inspection, appearance inspection, etc., when processing tape-like objects such as film carrier tape for mounting electronic components in the processing unit, it has good positional accuracy and accurate stop position. It is an object of the present invention to provide a tape-like material processing apparatus and a tape-like material processing method capable of performing reliable processing.

When the TAB tape T supplied to the inspection unit 30 passes between the back tension gear 32 and the drive gear 34, the drive of the drive gear 34 is temporarily stopped, and the supply of the TAB tape T is stopped. While being suspended,
The reverse rotation of the back tension gear 32 that engages with the sprocket hole of the TAB tape T allows the TAB tape T to be accurately positioned at a predetermined position, for example, with reference to the sprocket hole of the TAB tape T. (Pitch feed). In the figure, reference numerals 31 and 33 denote pressing rollers for pressing the TAB tape T between these gears.

Then, as shown in FIG. 1, the inspection unit 30 visually inspects, for example, a disconnection, a short circuit, a chip, or a projection by using a reflected light or a transmitted light. A microscope 36 such as a stereoscopic microscope is provided to perform the operation. And the TA where the defective part was found with this microscope
A marking section 40 for making a mark by inking, punching, or the like is arranged on the electronic component mounting section of the B tape T.

As described above, the marking unit 40
After a predetermined marking is made at a predetermined position of the defective portion of the TAB tape T, the TAB tape T is
And is supplied to the next winding device 50. FIG.
, The TAB supplied to the winding device 50
The tape T is driven by a drive motor (not shown) to rotate the take-up drive shaft 52 so that the take-up drive shaft 5 is rotated.
2 is wound around the reel R mounted on the guide roller 2 via the guide roller 42.

At this time, the spacer S fed from the reel R of the feeding device 20 is supplied to the reel R of the winding device 50 via the guide rollers 56 and 57 and the winding slack preventing device 59 and is interposed between the TAB tapes. The TAB tapes come in contact with each other and the ink adheres to another part.
The AB tape is protected from being damaged.

In the inspection device 10 of the present invention, the TAB tape T wound on the reel R is
After the tape is fed from the feeding roller 20 to the inspection unit 30 and before being supplied to the inspection unit 30 via the guide roller 21, the TAB tape T has a predetermined length between its reel R and the guide roller 21 due to its own weight. It is drooped by this amount, and T
A tension is applied to the AB tape T, and the AB tape T is supplied via a guide roller 21 to an inspection unit 30 provided with a stereo microscope or the like.

Similarly, after the inspection is completed in the inspection unit 30 and the TAB tape T on which a certain marking is given is guided through the guide roller 42, the TAB tape T is guided by the guide roller 42 and the winding device 50. TAB tape T between reel R
Is suspended by a certain length by its own weight, and a tension is applied to the TAB tape T by this own weight, and the TAB tape T is wound around the reel R of the winding device 50.

As shown in FIG. 2, on the delivery device 20 side, in order to detect the position of the TAB tape T suspended between the reel R of the delivery device 20 and the guide roller 21, the TAB tape T is arranged vertically. Three position sensors 71-7
3 is disposed on the side portion 14 of the main body 12 of the inspection device 10 on the side of the delivery device 20. That is, these position sensors 71 to 73 are composed of a first delivery position detection sensor 71 arranged above, a second delivery position detection sensor 72 arranged at an intermediate position, and a third delivery position detection sensor 72 arranged below. And a position detection sensor 73.

In this case, as shown in FIG. 2, when the lower end of the TAB tape T hung between the reel R of the feeding device 20 and the guide roller 21 is at the upper position A, the first Is detected by the sending-out position detection sensor 71. At this time, since the lower end of the TAB tape T is located at the upper position, the length of the TAB tape T hung between the reel R of the feeding device 20 and the guide roller 21 hardly exists, so that the TAB tape T is hung. Since the weight (gravity) of the TAB tape T hardly acts on the TAB tape T, the tension (tension) of the TAB tape T falls below a predetermined tension.

Therefore, at this time, as shown in FIG. 2, the control device (not shown) drives the delivery drive shaft 22 of the delivery device 20 to move the TAB tape T from the reel R of the delivery device 20 in the delivery direction. E, and the lower end of the TAB tape T is moved downward. Thereby, the reel R of the feeding device 20 and the guide roller 2
The length of the TAB tape T suspended between the tapes 1 and 2 is increased, and a predetermined tension is applied to the TAB tape T by its own weight.

On the other hand, when the lower end of the TAB tape T hung between the reel R of the feeding device 20 and the guide roller 21 is at the lower position B, it is detected by the second feeding position detecting sensor 72. Is done. In this case, T
Since the lower end of the AB tape T is at the lower position, the length of the hanging TAB tape T between the reel R of the feeding device 20 and the guide roller 21 is long, and the weight of the hanging TAB tape T (gravity) ) Acts on the TAB tape T and exceeds the predetermined tension.

Therefore, at this time, as shown in FIG. 2, the control unit (not shown) stops the delivery drive shaft 22 of the delivery device 20 and feeds the TAB tape from the reel R of the delivery device 20. Stop it,
Only the transport of the TAB tape T by the drive of the drive gear 34 acts to move the lower end of the TAB tape T upward.

Thus, the TAB tape T suspended between the reel R of the feeding device 20 and the guide roller 21
Is shortened so that the value of the tension applied to the TAB tape T by its own weight is within a predetermined range. Furthermore, as shown in FIG. 2,
When the lower end of the TAB tape T exceeds the lower position B and reaches the lower limit position C, the third feed-out position detection sensor 73 causes the lower end position of the hanging TAB tape T to reach a predetermined limit value. Is reached. In this case, the TAB tape T comes into contact with the floor surface and the TAB tape T
The entire inspection apparatus 10 is stopped by a control device (not shown) so as to prevent contamination and damage of the inspection apparatus 10.

On the other hand, as shown in FIG. 3, the winding device 50 and the guide roller 42
2 is controlled in the same manner as the TAB tape T suspended between the reel R of the feeding device 20 and the guide roller 21 in FIG. That is, as shown in FIG.
On the 0 side, the reel R of the winding device 50 and the guide roller 4
In order to detect the position of the TAB tape T suspended between the two position sensors 91, three position sensors 91 arranged vertically.
To 93 are the winding device 50 of the main body 12 of the inspection device 10.
Is disposed on the side 16 on the side of.

That is, these position sensors 91 to 9
Reference numeral 3 denotes a first winding position detection sensor 91 arranged above, a second winding position detection sensor 92 arranged at an intermediate position, and a third winding position detection sensor 93 arranged below. It is composed of in this case,
As shown in FIG. 3, when the lower end of the TAB tape T hung between the reel R of the winding device 50 and the guide roller 42 is at the upper position A, the first winding position is set. It is detected by the detection sensor 91.

At this time, since the lower end of the TAB tape T is at the upper position A, the length of the TAB tape T suspended between the reel R of the winding device 50 and the guide roller 42 hardly exists. TAB tape T to be hung
Does not substantially affect the TAB tape T, the tension (tension) of the TAB tape T falls below a predetermined tension.

Accordingly, at this time, as shown in FIG. 3, the drive of the winding drive shaft 52 of the winding device 50 is stopped by the control device (not shown), and the winding of the winding device 50 to the reel R is stopped. The lower end of the TAB tape T is moved downward by stopping the winding of the TAB tape T and causing only the transport of the TAB tape T by the drive of the drive gear 34 to act.

Thus, the TAB tape T suspended between the reel R of the winding device 50 and the guide roller 42
Try to increase the length of. Thus, the length of the TAB tape T hanging between the reel R of the winding device 50 and the guide roller 42 is increased, and a predetermined tension is applied to the TAB tape T by its own weight. I have.

On the other hand, if the lower end of the TAB tape T hung between the reel R of the winding device 50 and the guide roller 42 is at the lower position B, the second winding position detecting sensor 92 Is detected by In this case, T
Since the lower end of the AB tape T is at the lower position, the length of the hanging TAB tape T between the reel R of the winding device 50 and the guide roller 42 is long, and the weight of the hanging TAB tape T ( (Gravity) acts on the TAB tape T and exceeds a predetermined tension.

In this case, the control device (not shown) drives the feed drive shaft 22 of the winding device 50 to wind the TAB tape T on the reel R of the winding device 50, thereby winding the TAB tape T. Winding is performed in the direction G, and the lower end of the TAB tape T is moved upward. As a result, the value of the tension applied to the TAB tape T due to its own weight is set within a predetermined range.

Further, as shown in FIG.
When the lower end of the B tape T exceeds the lower position B and reaches the lower limit position C, the third winding position detection sensor 93 determines that the lower end position of the hanging TAB tape T is a predetermined limit value. Is reached. In this case, T
In order to prevent the AB tape T from contacting the floor and preventing the TAB tape T from being contaminated or damaged, the control device (not shown) stops the entire inspection apparatus 10.

With this configuration, the lower end of the TAB tape T hanging between the reel R of the feeding device 20 and the guide roller 21 and between the reel R of the winding device 50 and the guide roller 42 Is always located in a certain range between the upper position A and the lower position B. Therefore, the tension applied to the TAB tape in the inspection unit 30 always has a constant value. by this,
Since a constant tension is always applied to the TAB tape T, when performing the inspection process in the inspection unit 30 as a processing unit, a precise stop position can be obtained with high positional accuracy and reliable processing. Can be implemented.

In addition, instead of using a dancer roller to add tension to the tape-like material by the weight of the dancer roll as in the prior art, a constant tension is applied to the tape-like material only by the weight of the tape-like material itself. Is added. That is, only a relatively low tension is applied to the tape-shaped object by the weight of the tape-shaped object alone, and therefore, when the conveyance of the tape-shaped object is stopped for inspection, the conventional dancer roller is used. As in the case of using the device, the position is not shifted, an accurate stop position can be obtained with high positional accuracy, and reliable processing can be performed.

In this case, between the reel R of the feeding device 20 and the guide roller 21, and between the winding device 50
Hanging between the reel R and the guide roller 42
The length of the tape T may be appropriately set to a predetermined tension depending on the type and size of the TAB tape T. In order to make such a setting, as shown in FIG. 1, depending on the height of the inspection machine, the distance between the upper end position of the guide roller 21 and the first feed position detecting sensor 71 is determined. La is 20 to 30 cm, the upper end position of the guide rail 21 and the second
Distance Lb from the feed-out position detection sensor 72 is 3
It is desirable that the distance Lc between the floor surface and the third sending-out position detecting sensor 73 is 40 to 50 cm.

Although not shown, in order to reduce the influence of damage to the sprocket holes of the TAB tape T due to the reverse rotation of the back tension gear 32 and the influence on the accuracy of the stop position, and to reduce the tension applied to the TAB tape T, A clutch may be provided between the back tension gear 32 and its drive motor so that the torque applied to the back tension gear is controlled to a predetermined torque.

As such a clutch, a clutch of a type capable of controlling the torque with a very small current is desirable in order to easily control the torque and to install the clutch in a small place. Hysteresis clutch, powder clutch, etc. can be used. The powder clutch is an electromagnetic powder type that can generate torque almost proportional to the exciting current, can be used for continuous slip within the allowable slip rate, has little change in torque due to rotation speed, has excellent repeatability, It has a stationary integral structure, is easy to install, requires no maintenance, uses powder,
It has a long life. As such a hysteresis clutch, for example, "micro powder clutch / brake"
OP Series "(Ogura Clutch Co., Ltd.) can be used.

The hysteresis clutch generates a torque proportional to the exciting current, enables accurate torque control, allows continuous use of the slip within an allowable slip ratio, and has a mechanical contact portion due to electromagnetic torque transmission. Therefore, a stable torque can be generated semi-permanently, the coil is of a stationary type, is built into a shaft, is easily mounted on a machine, and requires no maintenance. As such a hysteresis clutch, for example, a "hysteresis clutch / brake"
H Series "(Ogura Clutch Co., Ltd.) can be used.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this. For example, in the above-described embodiment, the apparatus for processing a tape-like material according to the present invention may be replaced with an electronic component. Although an example in which the present invention is applied to an inspection device for a mounting film carrier tape has been described, the present invention is not limited to this. When performing processes such as screen printing, electrical inspection, and appearance inspection, a tape-like material is used. It can be applied when it is necessary to stop accurately and with high positional accuracy.

Further, in the above embodiment, the TAB tape is hung down on both the feeding device side and the winding device side to detect and control each with the three position sensors. Various changes can be made without departing from the purpose of the present invention. For example, the TAB tape alone may be hung down and detected by the position sensor.

According to the present invention, the position of the lower end of the tape-shaped material hanging between the feeding device and the processing unit and between the winding device and the processing unit is always the upper position and the lower position. It comes to be located within a certain range between the positions. Therefore,
The tension applied to the tape-shaped object in the processing unit always has a constant value. As a result, a constant tension is always applied to the tape-shaped material, so that when the inspection processing is performed in the processing unit, a precise stop position can be obtained with high positional accuracy and a reliable processing can be performed. be able to.

In addition, instead of using a dancer roller to add tension to a tape-like object by the weight of a dancer roll as in the prior art, a constant tension is applied to the tape-like object only by the weight of the tape-like object itself. In other words, since only a relatively low tension is applied to the tape-shaped object by the weight of the tape-shaped object alone, when stopping the conveyance of the tape-shaped object for inspection, As in the case where the conventional dancer roller is used, the position is not shifted, an accurate stop position can be obtained with high positional accuracy, and a reliable process can be performed.

Further, when the lower end of the tape-shaped object exceeds the lower position and reaches the lower limit position, the lower end position of the tape-shaped object hanging down is determined by the third position detecting sensor. It is detected that the limit value has been reached, the inspection device itself is stopped, and the tape-like material can be prevented from coming into contact with the floor surface, thereby preventing the tape-like material from being contaminated or damaged. Further, in the present invention, when performing processing such as screen printing, electrical inspection, and appearance inspection, when processing the film carrier tape for mounting electronic components in the processing unit, a high positional accuracy and an accurate stop position are obtained. Thus, the present invention is an extremely excellent invention that has many effects, such as being able to carry out a reliable processing.
