[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a double-sided adhesive which is a connecting material to a liquid crystal glass substrate for connecting a liquid crystal driving IC which is a TAB component to a pair of liquid crystal glass substrates which face each other. The present invention relates to an adhesive tape piece attaching apparatus and an adhesive tape piece attaching method for attaching an anisotropic conductive film piece (adhesive tape piece).

2. Description of the Related Art For example, in a manufacturing process of a liquid crystal panel, a liquid crystal driving substrate is formed on a liquid crystal glass substrate constituting a liquid crystal cell.
There is a step of mounting C.

Conventionally, a rubber connector or the like has been used to connect the glass substrate and the liquid crystal driving IC. However, in recent years, there has been a demand for smaller and lighter liquid crystal panels and a demand for mounting a backlight, and the connection by the above-mentioned rubber connector or the like has come to a limit.

Therefore, recently, as an IC for driving a liquid crystal,
A TAB (Tape Automated B) formed by inner lead bonding a semiconductor element to a thin cine film film-shaped film carrier with a circuit pattern formed on the surface.
onding) components are widely used.

This TAB component is a component as shown by 1 in FIG. 16, and each TAB component 1 is mounted around a pair of first and second liquid crystal glass substrates 2a and 2b constituting a liquid crystal cell 2. . The TAB part 1 and the first and second parts
An anisotropic conductive film (anisotropic conductive adhesive) is used for the connection with the circuit patterns formed on the liquid crystal glass substrates 2a and 2b.

This anisotropic conductive film (adhesive tape piece) is
It is a tape-shaped member as shown by 4 in FIG. 17, and is made of an anisotropic conductive material in which conductive particles are mixed in a thermosetting or thermoplastic resin film.

The anisotropic conductive film 4 is formed on the outer leads of the TAB component 1 and the first or second glass substrate 2a, 2 described above.
When the TAB component 1 and the first or second glass substrate 2a, 2b are pressed in a direction in which they are sandwiched between the wiring terminals b of FIG. The outer lead of the TAB component 1 and the first or second glass substrate 2a facing each other have conductivity only in the direction in which they are in contact with each other and sandwiched.
Only the wiring terminal 2b is electrically connected.

By the way, by using this anisotropic conductive film 4, the TAB component 1 and the first and second liquid crystal glass substrates 2a, 2 are formed.
When connecting with b, it is necessary to attach the anisotropic conductive film 4 to either the TAB component 1 or the liquid crystal glass substrates 2a and 2b in advance.

Of these, as shown in FIG. 17, a case will be described in which the anisotropic conductive film 4 is previously attached to the liquid crystal glass substrate (here, the second liquid crystal glass substrate 2b).

A large number of wiring terminals 5 for connecting the TAB component 1 are led out from the edge of the liquid crystal glass substrate 2b. Since the anisotropic conductive film 4 is a long tape-shaped member, it is cut into an anisotropic conductive film piece 4'having a desired length and attached to the wiring terminals 5 ...

When the simple matrix liquid crystal panel 2 shown in FIG. 16 is manufactured, the TAB component 1 is formed on the surfaces of the pair of first and second liquid crystal glasses 2a and 2b facing each other. Need to be implemented. Therefore, the anisotropic conductive film piece 4 ′ has the first,
The second liquid crystal glass substrates 2a and 2b are attached to the surfaces facing each other.

Since the anisotropic conductive film 4 (anisotropic conductive film piece 4 ') is a double-sided tape-like member having adhesiveness on both the front surface and the back surface, it prevents dust and the like from adhering. There is a need. For this reason, as shown in FIG. 18, release papers (protective tapes) 6a and 6b are attached to both surfaces of the anisotropic conductive film 4 in many cases.

Therefore, when the anisotropic conductive film 4 is adhered to the glass substrate 2b (2a), first, only the release paper 6b on the side facing the glass substrate 2b is peeled off, and then this anisotropic paper is released. Liquid crystal glass substrate 2 to which a conductive film 4 is attached
Before connecting the TAB part 1 to the b, the release paper 6 attached to the other surface of the anisotropic conductive film 4 before the connection.
It is necessary to peel off a.

The liquid crystal cell 2 is supplied to a mounting device (not shown) for mounting the TAB component 1 after undergoing such a pre-process. Then, this mounting apparatus is
The outer leads of the B component 1 are made to face the wiring terminals 5 of the first and second liquid crystal glass substrates 2a and 2b to which the anisotropic conductive film 4 is adhered, and then the liquid crystal is bonded using a bonding tool. Pressed against the glass substrates 2a, 2b,
By heating, the TAB component 1 is sequentially mounted on the liquid crystal cell.

Through the above steps, one simple matrix liquid crystal panel is completed.

[0016]

By the way, in response to the recent demand for thinning and downsizing of liquid crystal devices, the circuit patterns of the wiring terminals 5 ... Formed on the liquid crystal glass substrates 2a and 2b are further miniaturized. At the same time, the TAB component 1 is becoming smaller and higher in density.

Along with this, the liquid crystal glass substrates 2a, 2
The width of the anisotropic conductive film 4 attached to b tends to become smaller and smaller, and the conductive particles to be mixed are also miniaturized. Therefore, it may be necessary to handle it with caution.

The wiring terminal 5 and the TAB component 1 are also provided.
In order to cope with the miniaturization of the anisotropic conductive film 4, it is necessary to attach the anisotropic conductive film 4 with higher accuracy. Since it is easily stretched, slack is likely to occur and positioning is difficult.

Further, in the work of cutting the anisotropic conductive film 4 to form the anisotropic conductive film piece 4'and the peeling of the release papers 6a and 6b, the anisotropic conductive film 4 has a double-sided adhesive property. Since it is a member, it sometimes requires complicated and special technology.

For this reason, conventionally, the work of attaching the anisotropic conductive film 4 to the liquid crystal cell 2 has been performed manually or by a manual device.

However, in the case of using a manual or manual device, there is a limit to improving the manufacturability of the liquid crystal panel, and dust or the like is often attached to the anisotropic conductive film 4, which is not preferable. There's a problem.

The present invention has been made in view of the above circumstances, and can form an adhesive tape piece such as an anisotropic conductive film in a good and accurate manner, and can adhere the adhesive tape piece accurately.

On the lower surface of the Y-direction moving body 87, as shown in FIG. 5, a vertical guide plate 91 is fixed substantially vertically with its surface direction parallel to the surface of the vertical moving plate 26.

Further, as shown in FIG. 5, a mounting tool 93 for performing the above-described mounting operation and a crimping tool 9 for performing the crimping operation are provided on the front and back surfaces of the upper and lower guide plates 91, respectively.
4 and 4 are provided so as to be vertically movable via sliders 95 and 96, respectively.

The mounting tool 93 and the crimping tool 94 are vertically driven by separate vertical drive cylinders (not shown).

The lower end side of each tool 93, 94 is
They are a mounting portion 93a and a pressing portion 94a which are long in the feeding direction of the anisotropic conductive film piece 4 ', respectively. Also,
The upper surfaces of the mounting portion 93a and the pressing portion 94a and the vertical guide plate 91 are elastically connected in the vertical direction by a damper 95 shown in FIG.

By the action of the damper 95, when the anisotropic conductive film piece 4 ′ is pressed against the first liquid crystal glass substrate 2 a by the mounting tool 93 and the pressure bonding tool 94, the anisotropic conductive film piece 4 ′ is pressed. ′ Can be pressed with a substantially uniform pressure over the entire length in the length direction.

Incidentally, the mounting portion 93a of the mounting tool 93 described above.
Has a substantially flat lower end surface, and a suction hole 97 for adsorbing and holding the anisotropic conductive film piece 4'through the first release paper 6a is formed in the lower end surface in the width direction. A plurality of openings are made across. Each suction hole 97 is connected to a vacuum device (not shown) so as to generate a suction force on the lower end surface of the mounting portion 93a.

On the side surface of the mounting portion 93a, the anisotropic conductive film piece 4 adsorbed and held on the lower end surface of the mounting portion 93a.
A positioning mechanism 98 for positioning the ‘′ is provided.

This positioning mechanism 98 is shown in FIG. 2 and FIG.
As shown in FIG. 3, the contact body 99 rotatably supported by the protruding shaft 98a protruding outward from the middle portion in the height direction of both widthwise end faces of the mounting portion 93a is rotatably supported by the cylinder 100.
The anisotropic conductive film piece 4'is positioned by being brought into contact with one side of the anisotropic conductive film piece 4'which is suction-held on the lower end surface of the mounting portion 93a.

On the other hand, the crimping portion 94a of the crimping tool 94.
A heater shown by 101 in the drawing is embedded therein, and the lower end surface thereof is formed substantially flat like the mounting portion 93a of the mounting tool 93.

Therefore, the pressure-bonding tool 94 has its lower end surface brought into contact with the anisotropic conductive film piece 4'through the first release paper 6a, whereby the anisotropic conductive film piece 4'is brought into contact.
Can be softened and thermocompression bonded to the glass substrate 2a (2b).

Next, the means for peeling the first release paper 6a from the anisotropic conductive film piece 4'attached to the first liquid crystal glass substrate 2a in this manner will be described.

The clamp mechanism 61 peels off the first release paper 6a. That is, this clamp mechanism 61
As described above, the pair of chucks 62 are usually located above and below the first release paper 6a on the outer side of the sticking position A, and, if necessary, at the sticking position A.
It enters into the inside and is reciprocally driven along the first release paper 6a.

Therefore, by raising the vertical moving plate 26, the first release paper 6a is adhered to the glass substrate 2a by the lower chuck 62 of the pair of chucks 62, 62. The first release paper 6a can be lifted in a direction away from the anisotropic conductive film piece 4'and moved in such a state as to move the chuck 62 into the sticking position A. The anisotropic conductive film pieces 4'can be sequentially peeled off (see FIG. 1).
1).

In this way, the anisotropic conductive film piece 4'is formed.
The first release paper 6a peeled off from the first release paper 6a is fed and driven by the clamp mechanism 61, so that the sticking position A
It is ejected from the device and is sequentially wound by a winding mechanism 105 (shown in FIG. 2) provided on the vertical moving plate 26.

Next, the winding mechanism 105 will be described with reference to FIG.

The first release paper 6a discharged from the sticking position A passes through the above-mentioned second guide roller 83 and is then guided upward by the third and fourth guide rollers 106 and 107. It

The third and fourth guide rollers 106, 1
The first release paper 6a that has passed through 07 is the eighth roller 10
After being rolled into contact with the No. 8 roller, it is reversed downward by the ninth roller 109 and wound around the lower side of the tenth roller 110.

The tenth roller 110, like the first roller 32 and the fifth roller 39 described above, has the third slit 1 provided on the surface of the vertical moving plate 26.
It is held in 11 so that it can move up and down, and
It is urged downward (in a direction that gives tension to the first release paper 6a) by a third weight 12 shown in FIG.

Then, in the third slit 111,
The third slit 111 is provided so as to face an upper end portion (first position) and a lower end portion (second position) of the third slit 111.
An upper end sensor 114 and a lower end sensor 115 for detecting the zero roller 110 are provided.

After passing through the tenth roller 110, the first release paper 6a is taken up by the first release paper take-up reel 116 provided above the vertical moving plate 26. ing. The first release paper take-up take-up reel 116 is rotationally driven by a third drive motor 117 fixed to the vertical moving plate 26, and sequentially takes up the first release paper 6a. .

The third drive motor 117, like the first and second drive motors 44 and 45 for driving the supply reel 30 and the second release paper take-up reel 43 described above, has the upper end portion. Sensor 114 and lower end sensor 1
The control section 47 operates according to a command based on the detection signal from the control unit 15. When the control section 47 does not operate, the first release paper take-up reel 116 is held unrotatable. .

Next, the control of the feeding and winding operation of the anisotropic conductive film 4 and the first and second release papers 6a and 6b by the control unit 47 will be described with reference to FIGS. 6 (a) and 6 (b).
Will be described with reference to.

When the anisotropic conductive film 4 and the first and second release papers 6a and 6b are fed and driven, as described above, the clamp device 61 (chuck 62) operates, and FIG.
As shown in (a), the pair of chucks 62 are inserted into the attachment position A. Then, the first release paper 6a is clamped by the chuck 62 and moved in the direction shown by the arrow in the figure, so that the first release paper 6a is fed by a predetermined size.

At this time, the first drive motor 40 for driving the supply reel 30 is stopped and the supply reel 3 is
0 is held non-rotatable. Therefore, when the first release paper 6a is driven and driven by the chuck 62, the first roller 31 is pulled downward by the tension applied to the first release paper 6a, and the first weight 34 is pulled. It is lowered as shown in FIG. 7B against the upward urging force of.

At this time, the second and third drive motors 45 and 117 for driving the first and second release paper take-up reels 116 and 43 are stopped, and the first and second release papers are also stopped. The take-up reels 116 and 43 are non-rotatably held. Therefore, when the first release paper 6a is fed and driven, as shown in FIG.
The ninth and tenth rollers 110 descend due to the weight of the second and third weights 51 and 112, and prevent the second and first release papers 6a and 6b from being bent.

As a result, the first roller 31,
When the fifth roller 39 and the tenth roller 110 are lowered to the positions (second positions) of the lower end sensors 53 and 115, the control unit 47 causes the first to third drive motors 4 to operate.
0, 45, 117 are operated to move the supply reel 30 to the anisotropic conductive film 4 and the first and second release papers 6 respectively.
a, 6b in the feeding direction, the second release paper take-up reel 43 in the winding direction of the second release paper 6b, and the first release paper take-up reel 116 in the first release paper 6a. Drive in the winding direction.

As a result, the first roller 31 is raised by the urging force of the first weight 34, and the fifth and tenth rollers 39 and 110 are moved to the second and first release papers 6 and 6.
As b and 6a are wound up, they are driven upward against the biasing forces of the second and third weights 51 and 112.

As a result, the above first, fifth, and tenth
Rollers 31, 39, 110 of the upper end sensor 52,
When the height (first position) of 114 is restored, the control unit 47 causes the first to third drive motors 45, 4 by the detection signals from the upper end sensors 52, 114.
0 and 117 are stopped.

As a result, the anisotropic conductive film 4 and the first and second release papers 6a and 6b are fed and driven with a predetermined tension applied.

The first anisotropic conductive film piece sticking mechanism 17 described above and the second anisotropic conductive film piece sticking mechanism 18 provided with the reversing mechanism 20 in between are described above. Thus, it has substantially the same structure as the first anisotropic conductive film piece sticking mechanism 17.

However, the second anisotropic conductive film piece sticking mechanism 18 is provided with the liquid crystal supplied to the second anisotropic conductive film sticking position B (hereinafter referred to as "sticking position B"). Second of cell 2
16 along the Y side (Y1) of the liquid crystal glass substrate 2b of FIG.
As shown in, the anisotropic conductive film piece 4'shorter than the anisotropic conductive film piece 4'attached to the first liquid crystal glass substrate 2a.
It is a mechanism for partially sticking a plurality of sheets one by one.

Therefore, as compared with the first anisotropic conductive film attaching mechanism 17, the anisotropic conductive film piece 4'is attached to the second liquid crystal glass substrate 2a by the attaching portion 85 ( The configurations of the mounting tool 93 and the crimping tool 94) are slightly shorter in the width direction.

Further, since the second anisotropic conductive film attaching mechanism 18 is a mechanism for partially attaching the anisotropic conductive film piece 4 ', the second anisotropic conductive film attaching mechanism 18 is located below the attaching position B. The second back-up 15 provided on the lower surface of the second liquid crystal glass substrate 2b for holding the lower surface of the second liquid crystal glass substrate 2b has a length of the upper end holding portion as shown in FIG. It is formed shorter than the first bank-up 14 provided in.

Next, the overall operation of the anisotropic conductive film piece sticking apparatus will be described. First, when the cell stage 16 receives the liquid crystal cell 2 from the liquid crystal cell supply section 11,
It moves along the X guide rail 13 and stops at a position corresponding to the first anisotropic conductive film attaching mechanism 17.

An image pickup camera (not shown) is provided at this position, and the first liquid crystal glass substrate 2a of the liquid crystal cell 2 is provided.
The two positioning + marks (shown in FIG. 16) provided at both ends of the first X side (X1) of each are recognized.

The control unit 47 actuates the cell stage 16 based on the recognition signal from the image pickup camera, and sets the X side (X1) of the first liquid crystal glass substrate 2a to the first anisotropic conductive film. It is positioned on the first backup 14 provided at the attachment position A. This first backup 14
Is driven to rise, and the first liquid crystal glass substrate 2 is
Hold the lower surface of a. (The state shown in FIG. 7A) Next,
The operation of attaching the anisotropic conductive film piece 4'to the first X side (X1) of the first liquid crystal glass substrate 2a positioned at the first anisotropic conductive film attaching position A is illustrated. 7 (a) to FIG.
(J), It demonstrates based on FIG.

As shown in FIG. 7 (a), the anisotropic conductive film 4 is cut by the cutting mechanism 54 into anisotropic conductive film pieces 4'each having a predetermined size, and the first release paper 6a is cut. The suction nozzle 60 is driven by being intermittently driven at predetermined intervals.
Will be sent to the position corresponding to.

Of the anisotropic conductive film pieces 4'held on the first release paper 6a, the unnecessary anisotropic conductive film pieces 4 '' are
As shown in FIGS. 7A and 7B, the anisotropic conductive film peeling mechanism 64 provided at this position peels and removes the first release paper 6a. As a result, the first
Anisotropic conductive film piece 4'attached to the liquid crystal glass substrate 2a of
"Cue" is done.

When the "cueing" is performed, the anisotropic conductive film piece 4'is attached by the first release paper 6a being fed and driven as shown in FIG. 8 (c). It is supplied to the position A, and the adhesive surface faces the first liquid crystal glass substrate 2a.

The clamp mechanism 61 (chuck 62)
When the break sensor 63 detects a break in the anisotropic conductive film piece 4 ', the feeding of the first release paper 6a is stopped and the anisotropic conductive film piece 4'is positioned in the feeding direction. I do.

That is, the rear end portion in the feeding direction of the anisotropic conductive film piece 4'to be attached is 1. Positioning is performed with the protrusion of about 5 to 2.0 mm.

Then, in this state, the pair of first and second guide rollers 83, 83 for positioning act on both sides sandwiching the sticking position A, and the upper anisotropic conductive film piece 4 is formed.
′ ′ And the first release paper 6a are positioned and held in the width direction.

Then, as shown in FIG. 7D, the mounting tool 93 is driven downward, and the lower end surface of the mounting portion 93a is covered with the first release paper 6a holding the anisotropic conductive film piece 4 '. It is brought into contact with the upper surface and is adsorbed and held.

Then, in this state, the positioning mechanism 98 is operated to bring the abutting body 99 into contact with one side in the width direction of the anisotropically conductive film piece 4'which has been adsorbed and held. The adsorption posture of the conductive film piece 4'is corrected.

Next, as shown in FIG. 9E, the entire vertical moving body 23 holding the mounting tool 93, the cutting mechanism 54, etc. is driven downward. As a result, the mounting tool 93 attaches the anisotropic conductive film piece 4 ′ to the first
It is mounted on the first X side (X1) of the liquid crystal glass substrate 2a.

When the anisotropic conductive film piece 4'has been mounted, the vertical moving plate 26 is held at that height, and only the mounting tool 93 is driven upward. Then, above the attached anisotropic conductive film piece 4 ', a crimping tool 94 is positioned so as to face each other, as shown in FIG.

Next, this crimping tool 94 is shown in FIG.
As shown in (g), the anisotropic conductive film piece 4'is pressed down and heated at the lower end surface of the pressure-bonding portion 94a against the first liquid crystal glass substrate 2a while being heated. 'Is thermocompression bonded (attached) to the first liquid crystal glass substrate 2a
To do.

Also in this case, as shown in FIG. 12 (a), the anisotropic conductive film piece 4'has a rear end located outside the pressure-bonding portion 94a with a dimension of t = 1.5 to 2.0 mm. In the state of being squeezed out, the crimping portion 94a is crimped.

As a result, the heat generated by the crimping tool 94 is prevented from being transferred to the anisotropic conductive film piece 4'which is then crimped.

When the pressure bonding of the anisotropic conductive film piece 4'is completed, as shown in FIG.
4 and the chuck 62 of the clamp mechanism 61 are driven upward. As the chuck 62 rises, the first release paper 6a holding the anisotropic conductive film piece 4'attached to the first liquid crystal glass substrate 2a is pulled upward. Becomes

Then, as shown in FIG. 11 (i), the chuck 62 of the clamp mechanism 61 is attached to the crimping tool 94.
Between the first and second liquid crystal glass substrates 2a and moved to the feed side along the first release paper 6a, so that the chuck 62 located below the pair of chucks 62 can be operated. The first release paper 6a is attached to the anisotropic conductive film piece 4 '.
Can be peeled off. FIG. 12B is an enlarged view of the state after the release paper 6a is peeled off.

During this operation, the suction nozzle 60 sucks and holds the upper surface of the first release paper 6a, and the cut anisotropic conductive film piece 4'is displaced in the feeding direction. To prevent that.

When the peeling of the first release paper 6a is completed, the vertical drive plate 26 is driven upward as shown in FIG. 9 (j), whereby the entire first release paper 6a is removed. It is separated upward from the anisotropic conductive film piece 4 ′ attached.

Then, the chuck 62 once stops at the central portion (point A1) of the sticking position A from the position shown in the figure, grips the first release paper 6a, and then moves again. As a result, the first release paper 6a is fed and driven, and the anisotropic conductive film piece 4'to be attached next is supplied to the attachment position A. During this feeding drive, the suction by the suction nozzle 60 is released and the first release paper 6 is released.
a is smoothly fed and driven.

As a result of such a series of operations, the first liquid crystal glass substrate 2a shown in FIG.
As shown in (a), the anisotropic conductive film piece 4'is attached.

When the attachment of the anisotropic conductive film piece 4'to the first X side (X1) of the first liquid crystal glass substrate 2a is completed, the cell stage 16 causes the liquid crystal cell 2 to move. Is withdrawn from the attachment position A.

Next, when the cell stage 16 is retracted to a position where the liquid crystal cell 2 can be rotated in the horizontal plane (cell rotation position), the liquid crystal cell 2 is moved.
180 ° in the horizontal plane.

Then, again, this cell stage 16 is
This time, the image pickup camera (not shown) is made to recognize the positioning + marks provided at both ends of the second X piece (X2) of the first liquid crystal glass substrate 2a.

The cell stage 16 has the first liquid crystal glass substrate 2a based on the recognition by the image pickup camera.
The second X side (X2) is positioned at the sticking position A.

Then, the first anisotropic conductive film attaching mechanism 17 also applies the first anisotropic conductive film attaching mechanism 17 to the second X side (X2).
Similar to the case of the X piece (X1), the anisotropic conductive film piece 4'is attached by using the mounting tool 93 and the pressure bonding tool 94.

In this way, if the sticking of the anisotropic conductive film piece 4'on the first and second X sides (X1, X2) of the first liquid crystal glass substrate 2a is completed, The cell stage 16 replaces the liquid crystal cell 2 with the reversing mechanism 2.
Transfer to a position (reversal position) facing 0.

The liquid crystal cell 2 transferred to this inversion position is
After being turned upside down by the reversing mechanism 20, it is transferred again onto the cell stage 13. Next, the cell stage 16 moves the liquid crystal cell 2 out of the inversion position, and positions the liquid crystal cell 2 in a position (rotation position) where it can be rotated in the horizontal plane.

Next, the cell stage 16 rotates the liquid crystal cell 2 by 90 ° in the horizontal plane. The liquid crystal cell 2 rotated by 90 ° is transferred by the cell stage 16 to a position facing the second anisotropic conductive film piece sticking apparatus.

At this position, the cell stage 16 has an image pickup camera (not shown) for positioning + marks (shown in FIG. 16) provided at both ends of the Y side (Y1) of the second liquid crystal glass substrate 2b. Let it face and recognize.

The cell stage 16 attaches the liquid crystal cell 2 to the second anisotropic conductive film attaching position of the second anisotropic conductive film piece attaching mechanism 18 based on the recognition signal from the image pickup camera. Transfer to B.

The second anisotropic conductive film attaching mechanism 18 is
Since the device is a device for partially sticking the anisotropic conductive film piece 4 ′, the cell stage 16 is one of the Y sides (Y 1) of the second liquid crystal glass substrate 2 b forming the liquid crystal cell 2.
First, the portion where the anisotropic conductive film piece 4'is attached is the second
It is mounted on the backup 15.

Next, the second anisotropic conductive film sticking mechanism 18 operates in the same manner as the first anisotropic conductive film piece sticking mechanism 17 (FIGS. 7 (a) to 11 (j)). , Shown in FIG. 12), the anisotropic conductive film piece 4'is formed by using the mounting tool 93 and the pressure bonding tool 94.
Attach it to the Y side (Y1) of b.

In this way, the first anisotropic conductive film piece 4 is formed.
If 'is attached to a predetermined portion of the Y side (Y1) of the second liquid crystal glass substrate 2b, the cell stage 16
Shifts the second liquid crystal glass substrate 2a on the second backup 15, and then mounts a portion to which the anisotropic conductive film piece 4'is attached on the second backup 15.

Then, the second anisotropic conductive film attaching mechanism 18 attaches the anisotropic conductive film piece 4'to the portion by the same operation as described above. The cell stage 16 and the second anisotropic conductive film attaching mechanism 18 are the second
The same operation is further performed by shifting the position of the glass substrate 2b of
Then, as shown in FIG. 16, four anisotropic conductive film pieces 4'are attached along the Y side (Y1).

In this way, when the sticking of the anisotropic conductive film piece 4'on the second liquid crystal glass substrate 2b of the liquid crystal cell 2 is completed, the cell stage 16 moves the liquid crystal cell 2 It is delivered to the cell discharge mechanism 22.

The cell discharge mechanism 22 is the same as the chuck 2 described above.
After the liquid crystal cell 2 is gripped and lifted at 3, the liquid crystal cell 2 is discharged from the anisotropic conductive film piece sticking device.

The discharged liquid crystal cell 2 is the liquid crystal cell 2
Then, the TAB component 1 is delivered to a mounting device (not shown) for temporary and final pressure bonding.

According to the structure described above, the anisotropic conductive film 4 (anisotropic conductive piece 4 ') which is fine and difficult to handle is
The first and second glass substrates 2a and 2 which constitute the liquid crystal cell 2
There is an effect that it can be reliably attached to b with good and accurate dimensions. This will be described below.

That is, first, the anisotropic conductive film 4 and the first and second release papers 6a and 6b (hereinafter referred to as "anisotropic conductive film or the like") are unwound and wound up and down. Movable first, fifth, and tenth rollers 31, 39,
110 is provided, and the first, fifth, and tenth rollers 31,
Weights 34, 51, and 112 are connected to 39 and 110, respectively, and proper tension is applied to the anisotropic conductive film 4 and the release papers 6a and 6b.
The position of the rollers 31, 39, 110 is determined by the upper end sensor 52,
114 and the anisotropic conductive film 4 from the supply reel 30 based on the detection by the lower end sensors 53 and 115.
(Release paper 6a, 6b) is fed out, and the first and second release paper 6a, 6b are wound by the first and second release paper take-up reels 116, 43.

Conventionally, the anisotropic conductive film 4 and the release paper 6 are used.
In order to prevent the displacement of the a and 6b in the feeding direction, a means for fixing the supply reel or the like which houses the anisotropic conductive film 4 and the like in the rotational direction is adopted.

However, in this method, the tension applied to the anisotropic conductive film 4 or the like changes in the steps of pulling out and sticking the anisotropic conductive film 4 and then peeling off the first release paper 6a. Therefore, in recent years, the anisotropic conductive film 4 which has a narrow width and is easily stretched has a cutting position by the cutting mechanism 54 (the size of the anisotropic conductive film piece 4 ') and the liquid crystal glass substrate 2 described above.
The maximum sticking position for a and 2b is ± 3mm in the feed direction.
There were times when it was shifted.

However, according to the present invention, the anisotropic conductive film 4 and the first and second release papers 6a and 6b are always kept at a constant tension between the supply reel 30 and the suction nozzle 60. The supply reel 3 can be stretched and held.
This tension can be maintained even when the anisotropic conductive film or the like is fed from 0.

Therefore, since the anisotropic conductive film 4 having a small width and being easily stretched can be stretched without sagging, the anisotropic conductive film 4 can be accurately cut and has high dimensional accuracy. It becomes possible to manufacture the piece 4 '.

Secondly, this apparatus holds the anisotropic conductive film 4 with the first release paper 6a, and the anisotropic conductive film 4 has a predetermined size while leaving the first release paper 6a. The anisotropic conductive film piece 4'is cut into pieces, and then the first release paper 6a is fed and driven to supply the anisotropic conductive film piece 6a to the sticking positions A and B. After the anisotropic conductive film piece 6a was attached to the liquid crystal glass substrates 2a and 2b, the first release paper 6a was peeled off from the anisotropic conductive film piece 4 '.

Since the anisotropic conductive film 4 is a double-sided adhesive member, it is difficult to handle, and adhesion of dust or the like to the adhesive surface may cause poor connection.

However, according to the above configuration, the first
The anisotropic conductive film piece 4 ′ is manufactured by carrying the anisotropic conductive film piece 4 ′ with the release paper 6a of Example 1 without holding the adhesive surface of the anisotropic conductive film 4. , And the release of the first release paper 6a can be performed.
Therefore, the anisotropic conductive film piece 4'can be adhered well, and the occurrence of defective connection can be reduced.

Thirdly, the anisotropic conductive film piece 4'produced in this manner is maintained while the anisotropic conductive film piece 4'produced previously is attached to the glass substrates 2a, 2b. Is held and fixed by the suction nozzle 90.

Therefore, the release paper 6 formed by the above-mentioned attaching operation
Since it is not affected by the elongation of a and the position variation, it is unlikely that the position is displaced in the length direction before being supplied to the attachment position A. Therefore, there is an effect that the anisotropic conductive film piece 4 ′ can be attached with high accuracy without displacement.

In addition, at the attachment position A, the mounting tool 9 is
Since the anisotropic conductive film piece 4'is sucked and held on the lower end surface of the liquid crystal substrate 3, the first release paper 6a and the anisotropic conductive film piece 4'when mounted on the liquid crystal glass substrates 2a and 2b. There is an effect that it is possible to effectively prevent the occurrence of the problem of twisting.

Fourthly, in this embodiment, when the manufactured anisotropic conductive film piece 4'is attached to the glass substrates 2a, 2b or thermocompression bonded, the anisotropic conductive film held by the release paper 6a is used. The rear end portion of the piece in the feeding direction is projected to the outside by 1.5 to 2.0 mm from the end portions of the mounting tool 93 and the crimping tool 94. This has an effect that only the desired anisotropic conductive film piece 4 ′ can be reliably attached.

That is, in order to attach the anisotropic conductive film piece 4'to the glass substrates 2a and 2b most effectively, the anisotropic conductive film piece 4'is pressed by the tools 93 and 94. Is desirable.

However, according to this method, not only the anisotropic conductive film piece 4 ′ to be pressed but also the next adjacent anisotropic conductive film piece 4 ′ may be erroneously pressed.
Further, even during thermocompression bonding, the heat from the crimping tool 94 may be transferred to the next anisotropic conductive film piece 4 ', and this anisotropic conductive film piece 4'may also be thermally transferred to the glass substrates 2a and 2b. is there.

However, according to the present invention, the mounting tool 93 and the crimping tool 94 should be separated by 1.5 to 2.0 mm from the leading end of the anisotropic conductive film piece 4 ′ to be attached next in the feeding direction. Therefore, the anisotropic conductive film piece 4 to be attached next is erroneously pressed against the glass substrates 2a and 2b, or the heat from the pressure bonding tool 94 affects the anisotropic conductive film piece 4 '. It is possible to reduce the influence.

With these, there is an effect that only the desired anisotropic conductive film piece 4 ′ can be reliably attached.

Fifth, this apparatus uses the mounting tool 93 and the crimping tool 94, and the mounting and crimping are performed by separate tools.

Conventionally, the anisotropic conductive film piece 4 ′ is directly pushed down by the pressure bonding tool 94 and the liquid crystal glass substrate 2 is pressed.
The method of pressing and sticking to a and 2b was taken. However, with this method, when the anisotropic conductive film piece 4'is pushed down, the anisotropic conductive film piece 4'may shift in the width direction.

Since the anisotropic conductive film piece 4'is pressed directly against the liquid crystal glass substrates 2a and 2b with a large pressure, the anisotropic conductive film piece 4'is displaced in the width direction. Sometimes occurred.

However, according to the above-mentioned structure, the anisotropic conductive film piece 4'is first adsorbed and held by the mounting tool 93, and is mounted on the liquid crystal glass substrates 2a and 2b in a state where the anisotropic conductive film piece 4'is positioned. The anisotropic conductive film piece 4 ′ was crimped by the crimping tool 94. Therefore, the anisotropic conductive film piece 4
The liquid crystal glass substrate 2 in the state where ′ is positioned with high precision
There is an effect that it can be attached to a and 2b.

Sixthly, as a means for positioning the anisotropic conductive film piece 4 ′ in the feeding direction of the anisotropic conductive film piece 4 ′, the anisotropic conductive film piece 4 ′ is placed in the sticking position A. A break sensor 63 for detecting a break between 4'is provided, and the feeding of the anisotropic conductive film piece 4'is stopped based on a detection signal from the break sensor 63.

As a result, as described above, the positional relationship between the mounting tool 93 and the crimping tool 94 and the cut can be accurately defined, so that the anisotropic conductive piece 4 to be erroneously adhered next. It is less likely that the ‘′ will be attached to the glass substrates 2a and 2b, and the yield is improved.

Seventhly, in order to supply the anisotropic conductive film piece 4'to the sticking positions A and B, the suction nozzle 60 and the clamp mechanism 61 are used, and these are alternately operated, thereby The release paper 6a of No. 1 was fed and driven.

During the feeding operation, the clamp mechanism 6 is
In No. 1, when the first release paper 6a is not gripped (unclamped), the suction nozzle 60 sucks and holds the upper surface of the first release paper 6a.

Further, the sticking operation of the anisotropic conductive film piece 4'is carried out with the suction nozzle 60 sucking the upper surface of the first release paper 6a and the clamp mechanism 61 being unclamped. I did it.

As described above, the anisotropic conductive film 4 has a small width and is easily stretched. Moreover, the anisotropic conductive film piece 4'is attached, or the anisotropic conductive film piece 4'is attached to the first release paper 6
When the operation of peeling a is performed, the tension applied to the first release paper 6a changes, so this first release paper 6a and the anisotropic conductive film piece 4 held by this first release paper 6a.
May shift in the feed direction over the entire length, and stable positioning may not be possible.

However, according to the above-described structure, during the sticking of the anisotropic conductive film piece 4 and the peeling operation of the first release paper 6a, the suction nozzle 60 causes the first release paper 6a to move.
The anisotropic conductive film piece 4'is fixed in the feeding direction by sucking and holding the upper surface of the anisotropic conductive film piece 4'and the elongation that is about to occur in the anisotropic conductive film piece 4'and the first release paper 6a is the anisotropic direction. Conductive conductive film piece 4
It is made to be absorbed by the winding side of the first release paper 6a after being peeled off from the sheet.

As a result, the supply position of the anisotropic conductive film piece 4'can be stabilized, so that the anisotropic conductive film piece 4'can be attached with high accuracy. Also,
As already described in the second effect, since the cutting position by the cutting mechanism 54 is also stable, there is an effect that an anisotropic conductive film piece 4'having a stable size can be supplied.

Eighth, this device is provided with the suction nozzle 54.
An anisotropic conductive film piece peeling mechanism 64 for previously peeling and removing the unnecessary anisotropic conductive film piece 4'from the first release paper 6a is provided on the lower side.

When the sticking of the anisotropic conductive film piece 4'on the liquid crystal glass substrates 2a, 2b is started, an unnecessary anisotropic conductive film piece 4'having a short length and the like is manufactured. May be done. Since this anisotropic conductive film piece 4'cannot be attached to the liquid crystal glass substrates 2a and 2b, the unnecessary anisotropic conductive film piece 4'is removed in advance to obtain the required anisotropic conductive film. It is necessary to cue the piece 4 '.

Conventionally, such an unnecessary anisotropic conductive film piece 4 is used.
In order to remove ′ ′, the apparatus is manually stopped or a dummy substrate is prepared and the unnecessary anisotropic conductive film piece 4 ′ is attached to the dummy substrate to remove it. It was

However, in such a method, it is necessary to stop the device and manually perform the setup work such as peeling by hand or inserting a dummy substrate, which impedes continuous operation of the device. was there.

According to the above-mentioned structure, when the operation of the apparatus is started, the unnecessary anisotropic conductive film piece 4'is automatically peeled and removed, and the necessary anisotropic conductive film piece 4'is removed. Since it can be put out, there is an effect that automatic / continuous operation becomes possible.

Further, even when a defective anisotropic conductive film piece 4'having a short length or the like is manufactured during the operation of the apparatus, the defective anisotropic conductive film piece 4'is operated by the same operation. It can be removed, and even in this case, there is an effect that the productivity of products can be improved because it is not necessary to stop the device.

Next, a second embodiment of the present invention will be described with reference to FIG.

The second embodiment is a modification of the first embodiment with respect to the positioning of the anisotropic conductive film piece 4'in the feed direction. Therefore, the other components are the same as those in the first embodiment, and therefore, the same reference numerals are given and detailed description thereof is omitted.

In FIG. 13A, reference numeral 93a indicates a mounting portion of the mounting tool 93. In this example,
The anisotropic conductive film piece 4'to be adhered is made to have a rear end (cut) in the feeding direction aligned with the end of the mounting portion 93a, or
Alternatively, as shown in the figure, the mounting portion 93a is positioned in a state of protruding by about 0.3 mm from the end portion.

That is, by arranging the detection sensor 63 closer to the mounting tool 93 than in the first embodiment along the feeding direction of the anisotropic conductive film piece 4 ', the anisotropic conductive film The protruding amount of the membrane piece 4'is 0.3 mm
Is adjusted so that

In such a state, the anisotropic conductive film piece 4'is formed.
After the positioning in the feeding direction is completed, the mounting tool 93 is lowered to bring the lower end surface of the mounting portion 93a into contact with the upper surface of the release paper 6a as shown in FIG. 13 (a). The release paper 6a and the anisotropic conductive film piece 4'are suction-held.

In the first embodiment, as shown in FIG.
As shown in FIG. 5, the height of the lower end of the suction nozzle 60 and the height of the lower end surface of the mounting portion 93a are made substantially the same, and the anisotropic conductive film piece 4'is formed between the suction nozzle 60 and the mounting portion 93a.
Further, the release paper 6a is stretched so as to be substantially horizontal.

However, in this embodiment, as shown in FIG. 13 (a), the lower end surface of the mounting portion 93a of the mounting tool 93 is positioned about 1 mm lower than the lower end of the suction nozzle 60. The descending amount of the mounting tool 93 is set.

Thus, the anisotropic conductive film piece 4 stretched between the suction nozzle 60 and the mounting tool 93.
′ ′ And the release paper 6a are inclined at a predetermined angle.

Then, this apparatus, like the first embodiment described above, lowers the entire vertical moving body 26,
The anisotropic conductive film piece 4'which has been adsorbed and held is pressed against the glass substrate 2a (2b) to be mounted.

If the anisotropic conductive film piece 4'is attached,
Although not shown in this figure, like the first embodiment,
The anisotropic conductive film piece 4 ′ is thermocompression bonded by using the pressure bonding tool 94.

Then, the work of peeling the release paper 6a from the anisotropic conductive film piece 4'is carried out by using the clamp mechanism 61 in the same manner as in the first embodiment.

According to this structure, the following effects can be obtained.

In this embodiment, the anisotropic conductive film piece 4'is held by inclining the release paper 6a holding the anisotropic conductive film piece 4'which is to be attached next at a predetermined angle. Two
It was made to float from the upper surface of a.

As a result, the contact area between the anisotropic conductive film piece 4'to be attached next and the glass substrate 2a can be reduced, so that even if the heat from the pressure bonding tool 94 is transferred, Anisotropic conductive film piece 4'and glass substrate 2a
The sticking force between the anisotropic conductive film piece 4'and the release paper 6a can be made larger than the sticking force generated between and.

Therefore, the anisotropic conductive film piece 4'is not transferred to the glass substrate 2a, and only the desired anisotropic conductive film piece 4'can be attached to the glass substrate 2a. it can.

Also, unlike the first embodiment, the anisotropic conductive film piece 4'can be pressed over substantially the entire length, so that the anisotropic conductive film piece 4'can be securely attached. There is an effect that can be.

Next, FIG. 14A shows the third embodiment.
~ It demonstrates with reference to FIG.15 (d).

The operation is performed for each anisotropic conductive film piece 4 ', and this anisotropic conductive film piece 4'is continuously attached. In addition,
Since the configuration of the third embodiment is the same as that of the first embodiment, the same reference numerals are given and detailed description thereof will be omitted.

FIG. 14A is an enlarged view of the same state as FIG. 7A described in the first embodiment. That is, the anisotropic conductive film piece 4 attached to the glass substrate 2a.
An anisotropic conductive film piece 4 ″ formed to be shorter than the ′ ′ is in a state of being sucked and held by the suction nozzle 60 via the release paper 6 a.

[0217] The anisotropic conductive film piece 4 '' formed in this short form
Similarly to the first embodiment, the anisotropic conductive film piece peeling mechanism 64 is vertically driven to be transferred to the adhesive tape 67 and peeled from the release paper 6a. The peeled anisotropic conductive film piece 4 ″ is as shown by an arrow in FIG.
It is wound around the winding reel 69.

After the anisotropic conductive film piece 4'is cued in this way, the release paper 6a has the same length dimension as the peeled anisotropic conductive film piece 4 '' and the release paper. Only the feed is driven. Then, in this state, the cutting mechanism 54 is operated, and the short anisotropic conductive film piece 4 ″ for cueing is molded again.

Then, as shown in FIG. 15 (c), the release paper 6a is driven and driven by the same length as the anisotropic conductive film piece 4'attached to the glass substrate 2a, and the cutting mechanism 54 is operated. By operating the anisotropic conductive film piece 4 to be attached
To form ´.

At this time, since the short anisotropically conductive film strip 4 ″ faces the anisotropic conductive film stripping mechanism 64, the anisotropic conductive film stripping mechanism 64 moves up and down. Then, the anisotropic conductive film piece 4 ″ formed in the short length is peeled off.

As a result, as shown in FIG. 15 (c),
Between the anisotropic conductive film piece 4 ′ that is first attached and the anisotropic conductive film piece 4 ′ that is next attached, there is a space corresponding to the removed short anisotropic conductive film piece 4 ″. It is formed.

In this embodiment, such a cueing operation is repeated to form a constant gap between the anisotropic conductive film pieces 4'to be adhered. On the other hand, the anisotropic conductive film piece 4'to be attached is sent to the attachment position A and stopped, as shown in FIG. 15 (d).

As shown in FIG. 15D, the position where the anisotropic conductive film piece 4 ′ is stopped is such that the gap portion is aligned with the end of the mounting tool 93 or the crimping tool 94. Determined. That is, in the first and second embodiments, the rear end portion of the anisotropic conductive film piece 4'in the feeding direction is protruded from the tools 93 and 94 by a predetermined dimension, but in this embodiment, the tool 93 is protruded. , 94 within the lower end surface (on the right side of the alternate long and short dash line in the figure).

After that, the anisotropic conductive film piece 4'is transferred to the glass substrate 2a through the same steps as those in the first embodiment.
Attach it to and thermocompression-bond it. That is, first, the mounting tool 93 is lowered, and the anisotropic conductive film piece 4'is suction-held by the lower end surface of the mounting portion 93a of the mounting tool 93. Then, the entire vertical moving plate 26 is lowered to mount the anisotropic conductive film piece 4'on the glass substrate 2a.

Next, the pressure bonding tool 94 is opposed to the mounted anisotropic conductive film piece 4'and then lowered, and the anisotropic conductive film piece 4'is thermocompression bonded. Next, after raising the pressure bonding tool 94, the release paper 6a is peeled off using the clamp mechanism 61.

With such a structure, the effects described below can be obtained.

That is, as compared with the first and second embodiments, only the desired anisotropic conductive film piece 4'can be reliably adhered to the glass substrate 2a.

That is, in the third embodiment,
A predetermined gap (gap) between the anisotropic conductive film piece 4'which is currently attached and the anisotropic conductive film piece 4'which is next attached.
Since it is ensured that the anisotropic conductive film piece 4 ′ to be attached next is erroneously pressed, or the influence of heat from the crimping tool 94 is transmitted to this anisotropic conductive film piece 4 ′. Is few.

Therefore, as in the first and second embodiments, the anisotropic conductive film pieces 4'are accurately positioned with reference to the breaks between the anisotropic conductive film pieces 4 '. It is not necessary, as shown in FIG. 15D, by separating the tip of the anisotropic conductive film piece 4 ′ to be attached next from the mounting tool 93 and the crimping tool 94, the next anisotropic conductive film is removed.
