Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to mounting ACF (Anisotropic Conductive Film) on a substrate when mounting TAB (Tape Automated Bonding) on a substrate of a liquid crystal cell in a process of manufacturing a liquid crystal panel. A cutter device for cutting an ACF tape in a state in which the ACF is attached to a separator paper to a predetermined size for attachment, and particularly, the separator paper is kept in a continuous state,
The present invention relates to a device for half-cutting only the ACF part.

[0002]

2. Description of the Related Art A liquid crystal panel constituting a liquid crystal display has a liquid crystal cell in which two upper and lower transparent substrates having a predetermined circuit pattern or the like are laminated at a predetermined interval, and liquid crystal is sealed between them. The lower substrate in this liquid crystal cell has a shape larger than that of the upper substrate. A region where the upper substrate does not overlap is provided on four or three sides of the lower substrate, and a lead pattern is routed to this region. Then, a TCP provided with an inner lead and an outer lead is mounted on a film substrate on which a driver IC is mounted.
A control board is connected to the outer lead of P.
Here, by mounting the TCP, the lead pattern on the lower substrate side and the inner lead on the TCP side are electrically connected.

The pitch between the leads provided on the lower substrate and the inner leads of the TCP is extremely fine, and so-called TAB mounting method is used to mount the leads on both members so that they are electrically connected to each other reliably. Is widely used. In this TAB mounting method, an ACF in which conductive particles are dispersed in an electrically insulating binder resin is adhered to a lower substrate, TCP is bonded onto the ACF, and thermocompression bonding is performed to form leads on the lower substrate side. Is to be electrically connected to the inner leads of the TCP through the conductive particles.

As mentioned above, the ACF is attached to the lower substrate before the TCP is mounted on the TAB.
Since both sides of F have adhesiveness, the ACF tape in which ACF is laminated on the separator paper is used for easy handling. Then, the ACF tape is wound around a reel, the ACF tape is unwound from the reel, and the ACF tape is attached so as to be pressed against the lower substrate. Then, when the ACF tape is attached over a predetermined length, the end portion is cut, the separator paper is then peeled off, TCP is further mounted thereon, and then thermocompression bonding is performed.

[0005]

By the way, a plurality of TCPs are mounted on each side of the lower substrate, and there is a predetermined space between the mounted TCPs. If the ACF is adhered over the entire length of each side of the lower substrate, not only the space between the TCPs is wasted but also adhesive, so that the TCPs are placed in a predetermined position, When thermocompression-bonding TCP using a thermocompression-bonding member, there is a problem that the adhesive binder resin forming ACF adheres to the thermocompression-bonding member.

From the above points, in order to dispose the ACF only on the site where each TCP is placed, the ACF tape may be cut for each length of the TCP and attached to the required location. It is possible. However, in this way, A
There is also a problem in that the work of peeling the separator paper after attaching the CF tape becomes extremely troublesome, and it takes a lot of time for peeling.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a filter by which the ACF can be peeled from the separator paper at regular intervals so as to remove the ACF from the substrate. It is to make the sticking work easier.

[0008]

In order to achieve the above-mentioned object, the present invention is directed to a case in which an ACF tape in which ACF is laminated on a separator paper is cut at a predetermined size while being conveyed. A fixed guide member that guides the tape and an AC member that is disposed so as to face the fixed guide member.
A cutter having a blade edge longer than the width of F and capable of reciprocating displacement in a direction orthogonal to the running direction of the ACF tape is provided, and the fixed guide member is provided with a guide portion with which the separator paper of the ACF tape slides. A characteristic is that a cutter receiving portion is formed on both sides of the guide portion, the cutter receiving portion including a stepped portion that is raised by a dimension that does not exceed the thickness of the separator paper.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The ACF tape is wound around a supply reel, and the ACF tape is drawn so as to pass through a guide portion of a fixed guide member. A cutter is disposed opposite to the fixed guide member, and the feeding is stopped after the ACF tape is pulled out by a certain amount. In this state, the cutter is displaced toward the fixed guide member side. Cutter receiving parts are provided on both left and right sides of the guide part,
The cutter advances to a position where it abuts against the cutter receiving portion. As a result, the ACF tape is cut into a half-cut state, leaving a thickness corresponding to the step. That is, since the step in the cutter receiving portion does not exceed the thickness of the separator paper, at least the ACF is completely cut, but because of the step, the separator paper is not cut.

As described above, the ACF tape is cut into a predetermined length so that the ACF portion has a predetermined length, and the separator paper is in a non-cut state, that is, in a so-called half-cut state, where the substrate is positioned. It is pulled out up to and is pressed against a predetermined portion of the substrate by the cut length. Then, when the separator paper is separated from the substrate, the ACF is separated from the separator paper and attached to a predetermined portion of the substrate. In this state, the ACF tape is sent to a predetermined position and the liquid crystal panel is conveyed by a predetermined pitch interval, so that the ACF can be attached to a required position on the lower substrate over a required length.

To attach the ACF to the substrate, it is preferable to not only half-cut the ACF tape at predetermined intervals, but also to remove the ACF of a predetermined width from the cut line to expose the separator paper. This is advantageous in performing the automatic sticking of. For this purpose, a pair of cutters are used, the cutters are arranged at a predetermined interval in the running direction of the ACF tape, and the two cutters half-cut the ACF tape at two positions before and after the running direction. Then, the ACF between the front and rear cut lines is peeled and removed by the ACF peeling means.

Here, the ACF peeling means can be composed of, for example, a peeling tape having an adhesive surface and a pusher for pressing the peeling tape against the ACF. Press the adhesive surface of the release tape against the ACF with a pusher to bring it into pressure contact,
Next, when the peeling tape is displaced in the direction of separating from the ACF tape, the ACF between the front and rear cut lines is peeled off, and the separator paper is exposed.

Since ACF contains a binder resin having an adhesive property as a main component, if this binder resin adheres to the cutter, the sharpness is lowered. Therefore, in order to prevent such a situation from occurring, the cutter is heated above the curing temperature of the binder resin. As a result, even if the binder resin adheres to the cutter, the binder resin is immediately hardened by heating and becomes brittle, and is easily separated from the cutter.

[0014]

Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 shows an external view of the liquid crystal panel, FIG. 2 shows a cross section of the TCP mounting portion on the lower substrate, and FIG.
The structure of F tape is shown.

The liquid crystal cell 1 is, as is clear from FIG.
It is composed of a lower substrate 2 and an upper substrate 3 each made of a transparent plate, and these two substrates 2 and 3 are superposed on each other, and a liquid crystal is sealed between them. The lower substrate 2 is the upper substrate 3
It has a larger size and has three sides (or four) of the lower substrate 2.
The upper substrate 3 is exposed by a predetermined width in the side portion. A lead pattern is provided on the exposed portion of the lower substrate 2 by a printing means or the like. This lead pattern is a lead group 4 formed by a predetermined number of groups, and the lead groups 4 are provided in a plurality of groups on each side at predetermined intervals.

The TCP 5 is mounted on the lead group 4. The TCP 5 has a flexible substrate 5a, and a driver IC 6 is mounted on the flexible substrate 5a.
An inner lead group 7 and an outer lead group 8 are drawn out from the driver IC 6, respectively. TCP5
Is mounted so that the leads forming the inner lead group 7 are connected to the leads forming the lead group 4 of the lower substrate 2. Although not shown in the TCP5,
Further, a control board is connected to the outer lead group 8 side.

In order to mount the TCP 5 in a state in which the leads forming the inner lead group 7 are electrically connected to the leads forming the lead group 4 of the lower substrate 2, the ACF 9 is used.
Is used. As shown in FIG. 2, the ACF 9 is obtained by uniformly dispersing conductive particles 9b in a binder resin 9a having an electric insulation property, and by interposing the ACF 9, the leads constituting the lead group 4 are formed. 4a and the lead 7a in the inner lead group 7 are electrically connected via the conductive particles 9b. Therefore, TCP5 is TAB
In mounting, first, the ACF 9 is attached to the lower substrate 2, and the TCP 5 is superposed on the ACF 9 in an aligned state and thermocompression bonded.

Since the ACF 9 has adhesiveness on both front and back surfaces, as shown in FIG. 3, the ACF 9 is formed as an ACF tape 11 laminated on a separator paper 10 as a mount.
The ACF 9 is attached to a predetermined position of the lower substrate 2 by pressing the F tape 11 onto the area above each lead group 4 of the lower substrate 2 and peeling off the separator paper 10.
To attach this ACF 9, for example, the A shown in FIG.
A CF sticking device is used.

The ACF sticking apparatus has a supply reel 20 for supplying the ACF tape 11, and the ACF tape 11 delivered from the supply reel 20 has a half cut portion 21.
In, the ACF 9 part is cut and the liquid crystal cell 1
The ACF 9 is sent to the ACF sticking part 22 to be stuck to, and the length of the ACF 9 cut by the half-cutting part 21 is stuck to the part of the lower substrate 2 where the lead group 4 is provided. And A
A feed roller 23 including a drive roller 23a and a pinch roller 23b is provided on the downstream side of the CF sticking portion 22, and the drive roller 23a of the feed roller 23 is rotationally driven to run the ACF tape 11. I am trying to let you. Further, between the supply reel 20 and the feed roller 23, a plurality of guide rollers 24 are provided at appropriate places. Further, on the downstream side of the feed roller 23, a collecting section 25 for collecting the separator paper 10 after the ACF 9 is attached is provided.

The half-cut portion 21 for cutting the ACF tape 11 into half-cuts at regular intervals is composed of a fixed guide member 30, a cutter unit 31, and a peeling mechanism 32.

The fixed guide member 30 is the ACF tape 11
The separator paper 10 of the ACF tape 11 travels while slidingly contacting the fixed guide member 30. Here, the fixed guide member 3
0 has a predetermined length in the running direction of the ACF tape 11, and as shown in FIG. 5, a guide portion 30a composed of a concave portion having a width slightly wider than the width of the ACF tape 11 is formed in the central portion. The cutter receiving portions 30b are formed on both sides of the guide portion 30a. The step between the guide portion 30a and the cutter receiving portion 30b is smaller than the thickness of the separator paper 10 in the ACF tape 11.

As shown in FIGS. 6 and 7, the cutter unit 31 has a pair of upper and lower cutters 34, 34 on a unit main body 33 provided at a position facing the fixed guide member 30 in the traveling path of the ACF tape 11. It is the one that is installed. The blade edges 34a of both cutters 34 have a dimension longer than the width of the guide portion 30a of the fixed guide member 30, and are detachably attached to the respective cutter holders 35, and these cutter holders 35 are connected to the slide block 36. ing. The slide block 36 is engaged with a guide rail 37 provided on the unit body 33, and can reciprocate along the guide rail 37. A spring 38 acts on the slide block 36, which causes the cutter 34 to move to the unit main body 3
3, the cutter receiving portion 3 of the fixed guide member 30
It is urged in the direction of abutting 0b.

A cylinder 39 is attached to the unit body 33, and a pushing plate 39b is connected to the tip of a rod 39a of the cylinder 39. On the other hand, actuating plate pieces 40 are connected to both slide blocks 36, and the pushing plate 39b abuts on these actuating plate pieces 40 so that the cylinder 3
By contracting the rod 39b of No. 9, both slide blocks 39 are displaced in the direction of separating from the fixed guide member 30 against the biasing force of the spring 38.

When the rod 39a of the cylinder 39 is extended, the restriction on both slide blocks 36 is released. As a result, the biasing force of the spring 38 causes both slide blocks 36 to guide the ACF tape 11 by a fixed guide. Displaced towards the member 30, the cutter 34
Comes into contact with the ACF tape 11, and the cutting edge 34a cuts the ACF tape 11 at two positions in the front-back direction. Here, both cutters 34 are the unit main body 3
3 is not directly connected, but is elastically connected to the unit main body 33 via the springs 38, respectively. Therefore, even if there is an assembly error in both cutters 34 or the blades 34a have different degrees of wear, the cutters 34 are surely cut. Moreover, as shown by the phantom line in FIG. 5, the blade edge 34a of the cutter 34 can advance only to the cutter receiving portion 30b of the fixed guide member 30.
b, the guide portion 30a in which the separator paper 10 is in sliding contact
Since there is a step that does not exceed the thickness of the separator paper 10, only the ACF 9 part of the ACF tape 11 is cut, and the separator paper 10 is in a non-cut, half-cut state.

The cutter holder 35 has a built-in heater 35a. By heating the cutter holder 35 with the heater 35a, the cutter 34 in contact with the cutter holder 35 is heated. Here, the cutter 34 is heated by the binder resin 9a in the ACF 9.
It is set to be higher than the curing temperature of. As a result, even if the binder resin 9a is attached to the cutter 34 when the ACF tape 11 is cut, the binder resin 9a is immediately hardened and easily peeled from the cutter 34. As a result, it is possible to prevent the binder resin from adhering to the cutting edge 34a of the cutter 34 and deteriorating the sharpness thereof.

Further, as the peeling mechanism 32, a peeling tape 41 having an adhesive surface is used. As shown in FIG. 7, the peeling tape 41 is inserted from the supply reel 42 into a portion between the cutters 34 and wound on a take-up reel 44 which is rotationally driven by a motor 43. It is guided by the guide roller 45. In the area between the cutters 34, the adhesive surface of the peeling tape 41 faces the ACF tape 11, and the pusher 46 is arranged at the rear position of the peeling tape 41. The pusher 46 extends through the slide guide portion 33a of the unit main body 33, and has an end portion thereof at the connecting plate 4
7 is attached, and this connecting plate 47 is a cylinder 4
8 rods 48a. Therefore, rod 4
When 8a is extended, the tip of pusher 46 is
It is arranged in the retracted position retracted further to the side of the rod 48
When “a” is reduced, the pusher 46 projects so that the peeling tape 41 is displaced to the operating position where it is pressed against the ACF 9 portion of the ACF tape 11.

The present invention is constructed as described above, and its operation will be described below.

First, the ACF tape 11 is supplied to the supply reel 20.
Through the half cut portion 21 and the ACF attachment portion 22,
Drive roller 23a of feed roller 23 and pinch roller 23
Route it so that it can be inserted between b. Further, the peeling tape 41 is routed around the cutter unit 31 between the two cutters 34 so as to come into contact with the tip surface of the pusher 46.

The ACF tape 11 is positioned in the guide portion 30a of the fixed guide member 30, and the rod 39a of the cylinder 39 in the cutter unit 31 is extended. As a result, the cutter 34 advances the mounted slide block 36 by the urging force of the spring 38. As a result, both cutters 34
The blade edge 34a comes into contact with the ACF 9 on the ACF tape 11, and the ACF 9 is cut. However, when the cutting edge 34a of the cutter 34 advances from the ACF 9 to the part of the separator paper 10, it abuts the cutter receiving portions 30b located on both sides of the ACF tape 11, so that the cutter 3
4 does not move forward anymore, so that substantially only the ACF 9 is cut into a half-cut state. Thus, the cutter 34 is the cutter receiving portion 3 of the fixed guide member 30.
0b, but the cutter 34 is not directly connected to the unit main body 33 and the spring 38 is interposed therebetween, so that the cutter 34 elastically abuts the cutter receiving portion 30b. There is no risk of damage due to excessive pressing force applied to 34.

A pusher 46 is slidably provided in the unit body 33 between the cutters 34. The pusher 46 is located on the back side of the peeling tape 41. The pusher 46 is attached to the cylinder 48. Because they are connected,
When the rod 48a of the cylinder 48 is contracted, the pusher 46 advances to move the peeling tape 41 between the cut lines A by the cutter 34 of the ACF tape 11.
It will be pressed against CF9. As a result, the adhesive surface of the peeling tape 41 adheres to the ACF 9. Then, when the rod 48a of the cylinder 48 is contracted, the pusher 46 retracts, and at this time, the peeling tape 41 is displaced by the tension in the direction of separating from the ACF tape 11, and as a result, the peeling tape 41 is The ACF 9 between the cut lines adheres and is separated from the separator paper 10. Here, since the cutter 34 is held in contact with the ACF tape 11, the ACF 9 by the peeling tape 41 is held.
At the time of peeling, the separator paper 10 is not pulled. After that, when the rod 39a of the cylinder 39 is contracted, the pushing plate 39b connected to this rod 39a.
Pushes the operating plate piece 40 connected to the slide block 36 in the direction against the spring 38, so that the cutter 34 moves the ACF.
Separated from the tape 11.

When the ACF 9 is half-cut and the ACF 9 is peeled off between the cut lines as described above, the feed roller 23 is driven to feed the ACF tape 11 at a fixed size, and the peeling tape 41 is also located. By performing the above-described operation repeatedly in this state without feeding a fixed amount, the ACF tape 11 is sequentially half-cut and the ACF 9 between the cut lines is peeled off for each fixed dimension.

As described above, the ACF is performed in the half cut portion 21.
The ACF 9 is attached to the lower substrate 2 in the ACF attaching portion 22 by half-cutting the tape 11 in each fixed dimension and then removing the ACF 9 over a predetermined width to expose the separator paper 10. The work to be performed can be performed extremely smoothly and quickly.

Therefore, in the following, the ACF attaching portion 22
The work mechanism for attaching the ACF 9 will be described below.

Thus, in FIG. 4, 50 is the liquid crystal cell 1.
Is a base on which is mounted, and this base 50 is moved in the direction of arrow A in FIG.
A work of attaching the ACF 9 is performed. At the upper and lower parts of the liquid crystal cell 1 placed on the base 50, the upper roller 5 is provided.
1 and a lower roller 52 are provided so as to be vertically movable. Here, the upper roller 51 is a heating and pressing roller, and the lower roller 52 is a receiving roller that receives the load of the upper roller 51. ACF tape 11 is provided on the front and rear parts of the upper roller 51.
Guide roller 2 in order to keep the
4 are provided. Further, on the downstream side of the upper roller 51, the peeling pin 5 is provided at a position close to the upper roller 51.
3 are provided. The peeling pin 53 is provided between the ACF tape 11 and the lower substrate 2 at a position spaced from the lower substrate 2 by a predetermined distance. The drive roller 23a of the feed roller 23 is driven in synchronization with the lower roller 52. Therefore, a transmission belt 54 is provided between the lower roller 52 and the drive roller 23a in a wound manner. There is. In addition, the drive roller 23a is rotationally driven in synchronization with the lower roller 52 and can also rotate independently. For this reason, the motor 55 is connected to the drive roller 23a via a one-way clutch. .

The ACF adhering portion 22 is constructed as described above, and the lower substrate 2 of the liquid crystal cell 1 is located slightly before the end of the lead group 4, that is, the ACF 9 is the adhering end. The ACF tape 11 is arranged such that the upper roller 51 faces the position, and the ACF tape 11 is half-cut in the front and rear portions of the ACF 9 in the half-cut portion 21, and the ACF 9 in that portion is peeled off. The base 50 and A so that the peeling portion reaches the portion of the upper roller 51.
Adjust the position of the CF tape 11. In this state, the upper roller 51 is lowered and the lower roller 52 is raised so that the lower substrate 2 of the liquid crystal cell 1 is held by both rollers 52, and the ACF tape 11 is fixed on the lower substrate 2 by the upper roller 51. Press with the load of.

In this state, when the base 50 is moved in the direction of arrow A in FIG. 4, the upper roller 51 rolls on the separator paper 10 of the ACF tape 11, and the lower roller 52 is placed on the lower surface of the lower substrate 2. It will roll along and this lower roller 5
Since the rotation of 2 is transmitted to the driving roller 23a of the feed roller 23 via the transmission belt 54, the feed roller 23 rotates and the ACF tape 11 is fed in synchronization with the movement of the lower substrate 2. As a result, the ACF tape 11 is attached to a predetermined position on the lower substrate 2, and at the same time, the peeling pin 53 lifts the ACF tape 11 at the position on the downstream side of the upper roller 51. Therefore, as shown in FIG.
Peeled off from As a result, of the ACF tape 11,
The ACF 9 is thermocompression-bonded to the lower substrate 2 by the rolling of the upper roller 51, the separator paper 10 is peeled off, and the separator paper 10 is recovered by the recovery unit 25.

When the next ACF peeling portion of the ACF tape 11 is sent to the contact portion of the upper roller 51 with the lower substrate 2, the upper roller 51 is raised and the lower roller 52 is lowered. As a result, the ACF 9 is attached to a predetermined portion of the lower substrate 2, and the separator paper 10 is peeled off. If the peeling pin 53 is displaced slightly upward when the upper roller 51 is raised, the peeling of the end portion of the ACF 9 is performed more reliably.

In this state, the base 50 is moved by a predetermined amount, and the liquid crystal cell 1 is moved until it reaches the sticking end position of the ACF 9 slightly before the end part of the next lead group 4 on the lower substrate 2. . Also, depending on the width of the ACF peeling portion of the ACF tape 11, when the width of the ACF peeling portion has a certain length, the motor 55 is operated and the ACF tape 11 runs slightly. Then, the lower substrate 2 is aligned with the ACF attachment site. Then, by repeating the same operation as described above, the ACF 9 is attached to the next ACF attaching portion.

As described above, the ACF attaching section 22
Prior to attaching 9 to the lower substrate 2, the ACF tape 11
Among them, the ACF 9 part is cut and the separator paper 10
Is half-cut so as to be in a non-cutting state, and further, the front and rear portions are half-cut to remove the ACF 9 between both cut lines.
The work of attaching the CF 9 can be performed extremely easily and smoothly.

However, in the case where the above-mentioned mechanism is used as the ACF attaching portion, it is necessary to perform half-cutting in front and rear at two places to peel off the ACF in the portion between them.
Depending on the mechanism of the CF adhering portion, it may not be necessary to peel off the ACF. In this case,
It suffices to perform half-cutting with one cutter, and there is no need to provide a peeling tape.

As described above, according to the present invention, the ACF
The tape is arranged to be guided by the fixed guide member and is made to travel, and a cutter capable of reciprocating displacement in the direction orthogonal to the running direction of the ACF tape is disposed opposite to this fixed guide member, and the separator of the ACF tape of the fixed guide member is arranged. A cutter receiving part consisting of a stepped part that is raised by a dimension that does not exceed the thickness of the separator paper is formed on both sides of the guide part with which the paper slides, so that the ACF can be separated from the separator paper at regular intervals. ACF tape half cut
There is an effect that it can be performed easily and surely.
