Abstract

PROBLEM TO BE SOLVED: To excellently stick cut pieces of an anisotropic conductor to substrates by eliminating the interference between adjacent cut pieces at the time of press-sticking the anisotropic conductor to the substrate by cutting the conductor into the pieces by notching a tape. SOLUTION: The anisotropic conductor 1 stuck to one surface of the tape 2 is notched with a cutter 8 at every prescribed length in the advancing direction A of the tape 2 from the tape 2 side, and the portions of the conductor 1 between the notches are suck to the substrates, i.e., works. As the notches, two notches L1 and L2 are formed so that a prescribed interval may be formed between the adjacent notched portions of the conductor 1. Then a gap is formed between the adjacent notched portions of the conductor 1 on the tape 2 by peeling the portion (span-cut piece SC) between the notches L1 and L2 from the tape 2 with an adhesive tape 41. Thereafter, a step of sticking peeled portions of the anisotropic conductor 1 to the works is performed.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for attaching an anisotropic conductor to a work.

[0002]

2. Description of the Related Art In a process of mounting an electronic component on a work such as a liquid crystal panel or a substrate, an anisotropic conductor sticking apparatus for sticking an anisotropic conductor to a work is used.

In this anisotropic conductor bonding apparatus,
The anisotropic conductor attached to one side of the tape is cut along the tape in the direction of travel by a cutter at predetermined lengths, and the anisotropic conductor between the cuts is cut into a work such as a liquid crystal panel. (See Japanese Patent Application Laid-Open No. H10-27820 and the like).

FIGS. 8 to 10 schematically show an anisotropic conductor sticking process in a conventional anisotropic conductor sticking apparatus of this kind. First, as shown in FIG.
The tape 2 having the anisotropic conductor 1 adhered to one surface is fed by a feed roller 3 from a supply reel (not shown). The traveling direction of the tape 2 is first changed downward (in the direction of arrow A) by the guide roller 4, changed in the horizontal direction by the next guide roller 5, and further advanced again by the next guide roller 6. Change direction,
The tape 2 after the anisotropic conductor 1 has been peeled off by the take-up reel 7 is taken up.

[0005] Further, between the guide roller 4 and the guide roller 5, the anisotropic conductor 1 adhered to the tape 2 is disposed.
A cutter 8 is provided which cuts at predetermined intervals along the traveling direction of the tape 2, and the anisotropic conductor 1 is cut at predetermined intervals by the cuts.

A pressure bonding head mechanism 9 and a substrate support 10 are provided between the guide roller 5 and the guide roller 6. The crimping head mechanism 9 includes a crimping tool 11 and
The crimping tool 11 comprises a cylinder 12 for reciprocating with a rod 13. Although not shown, a heater for heating the anisotropic conductor 1 is provided in the crimping tool 11.

A substrate 14 serving as a work such as a liquid crystal panel is placed on the substrate support table 10, and the substrate 14 moves intermittently in the direction of arrow B. An anisotropic conductor peeling mechanism 15 is provided near the pressure bonding head mechanism 9.

The anisotropic conductor peeling mechanism 15 includes a cylinder 16, a drive shaft 17 that can reciprocate by the cylinder 16, and a peel roller 18 that is rotatably attached to the tip of the drive shaft 17. It is configured.

In such a configuration, the anisotropic conductors between the cuts (hereinafter, each anisotropic conductor 1a,
1b, 1c,... Reach the pressure bonding head mechanism 9 (in the state of FIG. 8, the anisotropic conductor 1a has reached the pressure bonding head mechanism 9). The rod 13 is driven. Thus, the pressure tool 11 presses the tape 2 against the substrate 14 to perform the operation of pressing the anisotropic conductor 1a onto the substrate 14 (the state of FIG. 9).

When the crimping operation is completed, the crimping tool 11 returns to the original position. However, the anisotropic conductor peeling mechanism 15 operates in the stage immediately before the return operation is performed, that is, in the state of FIG. To start.

That is, in the state shown in FIG. 9, the drive shaft 17 of the anisotropic conductor peeling mechanism 15 is driven in the horizontal direction,
The peeling roller 18 provided at the leading end comes into contact with the tape 2. At this time, the anisotropic conductor 1a is in a state of being bonded to the substrate 14 by heating by a heater (not shown). In this state, the pressure tool 11 is returned upward, the peeling roller 18 is further advanced, and the tape 2 is wound on the take-up reel 7, whereby the tape 2 is anisotropically conductive as shown in FIG. Body 1a
Is peeled off from the tape 2.

When the crimping tool 11 returns to the original state, the anisotropic conductor 1b to be crimped next reaches directly below the crimping tool 11, and the above-described crimping operation is repeated. At this time, since the substrate 14 has also been moved in the direction of arrow B, the operation described above
The anisotropic conductor 1a pressed on the substrate 4 has been moved to a predetermined position, and after the anisotropic conductor 1a, the next anisotropic conductor 1b is The crimping operation is performed continuously.

[0013]

The above described anisotropic conductor 1 (1a, 1b, 1c,...) Is pressed on the substrate 14 so that a predetermined pressure is applied on the substrate 14. Conductors 1a, 1b, 1 cut into lengths
.. are put in a state where they can be pasted. Conventionally, when making a cut in the anisotropic conductor 1, the cut is made by pressing the blade of the cutter 8 so that the length between the cuts is equal to each of the anisotropic conductors 1a and 1b. , 1c, ...
.. to form respective anisotropic conductors 1a, 1b, 1
are heated by the pressing tool 11 and pressed on the substrate 14. The cuts formed between the anisotropic conductors 1a, 1b, 1c,... Are extremely thin lines corresponding to the thickness of the blade of the cutter 8.

For this reason, as described with reference to FIGS. 8 to 10, when the anisotropic conductor 1a is pressed on the substrate 14, the next adjacent anisotropic conductor 1b also has its front end in front. Is located near the entry side end of the crimping tool 11 in a state of being continuous with the anisotropic conductor 1a, and the tip of the anisotropic conductor 1b interferes or heat is applied to that portion. It will be lost. Then, when the crimping operation of the anisotropic conductor 1a is completed, it is now the turn to crimp the anisotropic conductor 1b, and reaches the proper position of the crimping tool 11. If the body 1b has already been heated once, there is a problem that a good adhesion state cannot be obtained even if heat is applied again to the body once heated.

As described above, in the conventional anisotropic conductor sticking device, the cut provided in the anisotropic conductor 1
, The adjacent anisotropic conductors 1a, 1b, 1c,... Are supplied to the crimping tool 11 continuously in almost contact with each other.
For this reason, there arises a problem that interference occurs between adjacent anisotropic conductors that are next to the adjacent anisotropic conductor during crimping or the like, thereby causing adverse effects.

Accordingly, the present invention eliminates interference between adjacent anisotropic conductors when the respective anisotropic conductors present between the cuts are pressed on a work, and provides good work to the work. It is an object of the present invention to provide an anisotropic conductor bonding method and an anisotropic conductor bonding apparatus which can obtain an adhesion state.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, first to third embodiments of an anisotropic conductor bonding method and an anisotropic conductor bonding apparatus according to the present invention will be described with reference to FIGS. I do.

[First Embodiment] FIG. 1 is a view for explaining a first embodiment of an anisotropic conductor sticking apparatus according to the present invention. As the body sticking device, the same device as the conventional anisotropic conductor sticking device shown in FIGS. 8 to 10 is used. The difference between the anisotropic conductor sticking apparatus described in the first embodiment and the conventional anisotropic conductor sticking apparatus shown in FIGS. The method of insertion and the method of processing the cut are the same as those of the conventional configuration, and the same parts as those of the conventional anisotropic conductor bonding apparatus shown in FIGS. The description of the same parts will be omitted. Hereinafter, the first embodiment of the present invention will be described in detail.

The anisotropic conductor bonding apparatus according to the first embodiment includes anisotropic conductors 1a and 1b in addition to the components shown in FIGS. , 1c,
And a cutter driving unit 30 that performs cutter drive control such that two cuts are formed so that a predetermined interval is formed between adjacent anisotropic conductors. Gap forming means 40 is provided to form a gap between adjacent anisotropic conductors on the tape 2 by stripping an extra anisotropic conductor existing between the two cuts from the tape 2. Like that.

The two cut lines L1 and L2 are formed so that a predetermined space is formed between the above-described anisotropic conductors.
(See FIG. 2 and other figures.) The extra anisotropic conductor portion existing between the two cuts L1 and L2 is referred to as a span cut portion SC, and these two cuts L1 and L2 and the span cut The part SC will be described with reference to FIG. The gap between anisotropic conductors formed by stripping the span cut portion SC from the tape 2 is represented by G
(See FIG. 3), and this gap G is also described in FIG.

Hereinafter, a step of forming the span cut portion SC and stripping the span cut portion SC from the tape 2 form gaps G between anisotropic conductors adjacent to each other on the tape 2. The steps will be described with reference to FIGS.

2 (a) to 2 (c), the tape 2 to which the anisotropic conductor 1 has been applied is traveling from the upper side to the lower side (the direction of arrow A) in the figure. A cutter 8 and a cutter driving unit 30 for driving the cutter 8 exist on the path, and a gap forming unit 40 also exists.

The cutter 8 is pressed by a cutter drive unit 30 in the direction indicated by an arrow x (in the direction perpendicular to the direction in which the tape travels) to cut the anisotropic conductor 1 attached to the tape 2 into its blade 8.
An operation such as pushing off with a is performed. When the cutter 8 is pressed at a predetermined timing by the cutter driving unit 30, a first cut L1 is formed in the anisotropic conductor 1 as shown in FIG.

It should be noted that the cutter 8 immediately returns in the direction of the arrow x 'after making the first cut L1, and returns to the original position. FIG. 2A shows that the cutter 8 has the first cut L1.
After performing the operation of providing, the state is returned to the original position.

Then, after performing the operation of cutting the first break L1, with the tape 2 slightly advanced,
The cutter 8 is pressed in the arrow x direction by the cutter driving unit 30 as described above, and performs an operation of pushing off the anisotropic conductor 1 attached to the tape 2 as shown in FIG. 2B. FIG. 2B also shows that the cutter 8 has the second cut L
2 shows a state in which it returns to its original position after performing the operation of carving 2.

By controlling the driving of the cutter 8 by the cutter driving unit 30 as described above, the anisotropic conductor 1
As shown in FIG. 2 (b), a first cut L1 and a second cut L2 are formed in the slab to form a span cut portion SC. The distance between the first cut L1 and the second cut L2, that is, the width W of the span cut portion SC is about 1 mm to 2 mm in this embodiment. The cutter drive timing for cutting the first cut L1 and the cutter drive timing for cutting the second cut L2 are as follows.
It can be determined in advance depending on the traveling speed of the tape 2 and the size of the span cut SC.

As described above, as the tape 2 advances in the downward direction (the direction of arrow A), the cutter driving section 30 drives the cutter 8 at a predetermined timing, whereby the first cut L1 And the second cut L2 is cut. A span cut portion SC is formed between the first cut L1 and the second cut L2, and a predetermined length of anisotropic material to be attached to the substrate 14 is provided before and after the span cut portion SC. Conductor 1 (1a, 1b, 1c, ...)
Is formed.

Then, as the next step, the span-cut portion SC is peeled off by using the gap forming means 40, so that the adjacent anisotropic conductors 1a, 1b, 1c,.
A process for forming a gap G is performed.

The gap forming means 40 used in the first embodiment includes an adhesive tape supply reel 42 serving as an adhesive tape supporting means for supporting the adhesive tape 41 and an adhesive tape winding reel 4 for winding the adhesive tape 41.
3, a pressing plate 44 for pressing the adhesive tape 41, and a pressing plate driving unit 45 for controlling the driving of the pressing plate 44.

That is, the adhesive tape 41 is attached between the adhesive tape supply reel 42 and the adhesive tape take-up reel 43 such that the adhesive surface 41a faces the anisotropic conductive surface 1 attached to the tape 2. As the adhesive tape take-up reel 43 rotates, it can advance in the direction of arrow C. Further, the pressing plate driving unit 45 detects the timing when the span cut portion SC reaches the pressing position of the pressing plate 44, presses the pressing plate 44 at that timing, and thereafter returns the pressing plate 44 to the original position. It performs such an operation. In addition, the width of the tip of the pressing plate 44 is substantially the same as the width W (1 mm to 2 mm) of the span cut portion SC.

The gap forming means 40 has such a structure, and when the pressing plate driving section 45 detects that the span cut portion SC has reached the pressing position of the pressing plate 44,
The pressing plate driving section 45 presses and drives the pressing plate 44, and FIG.
As shown in (c), the pressure-sensitive adhesive tape 4 is
The one adhesive surface 41a is pressed against the span cut portion SC. Thus, the span cut portion SC is adhered to the adhesive surface 41a of the adhesive tape 41, and when the pressing plate 44 performs an operation of returning to the original position, the span cut portion SC is peeled off from the tape 2.

As described above, in the first embodiment, first, the cutter driving unit 30 drives the cutter 8 to cut the first and second cuts L1 and L2, thereby forming the span cut portion SC. Is formed, and then
An operation of stripping the span cut portion SC with the adhesive tape 41 is performed.

By performing such an operation in accordance with the flow of the tape 2, the tape 2 on which the anisotropic conductor 1 is adhered
Is as shown in FIG. That is, the anisotropic conductors 1 on the tape 2 are anisotropic conductors 1a,
1b, 1c,..., And between adjacent anisotropic conductors (between the anisotropic conductor 1a and the anisotropic conductor 1b, between the anisotropic conductor 1b and the anisotropic conductor). 1 to 2 which substantially correspond to the span cut portion SC.
A gap G of about mm is formed.

The tape 2 in the state as shown in FIG. 3 is supplied to the pressure bonding tool 11 via the guide roller 5 in FIG. Each anisotropic conductor 1
a, 1b, 1c,... are pressed. When the crimping is performed, for example, when the anisotropic conductor 1a is present immediately below the crimping tool 11 and the crimping is performed, the next anisotropic conductor 1b becomes the anisotropic conductor. Since the gap G exists between the anisotropic conductive member 1a and the anisotropic conductive member 1a, it is possible to reduce the influence of heat applied to the anisotropic conductive member 1a when the anisotropic conductive member 1a is pressed.

When the pressing operation of the anisotropic conductor 1a is completed in this manner, the anisotropic conductor peeling mechanism 15 operates (an operation example of this peeling mechanism has been described with reference to FIGS. 8 to 10; Is omitted), the anisotropic conductor 1 from the tape 2
a is peeled off. The tape 2 from which the anisotropic conductor 1a has been peeled off is taken up on the take-up reel 7 side, and the next anisotropic conductor 1b is disposed immediately below the crimping tool 11, and is pressed against the anisotropic conductor 1b. An operation is performed.

On the other hand, the substrate 14 has also moved forward (to the right in FIG. 1) and has reached a position where the anisotropic conductor 1b can be pressed. Then, in this state, the pressure bonding of the anisotropic conductor 1b is performed by the pressure bonding tool 11. Also at this time, the next anisotropic conductor 1c has a gap G between itself and the anisotropic conductor 1b. The anisotropic conductor 1c can be made less susceptible to the influence of heat applied to the conductor 1b.

As described above, in the first embodiment, when cutting the anisotropic conductor 1 stuck on the tape 2, the cutter drive is performed twice so that the adjacent anisotropic conductor 1 is cut. 1mm to 2mm span cut portion SC between conductive conductors
Is formed, and the span cut portion SC is formed with an adhesive tape 41.
By stripping off the adjacent anisotropic conductors 1a,
A gap G of about 1 to 2 mm is formed between 1b, 1c,. And the thing in such a state is supplied to the crimping tool 11 to perform a crimping operation.

Thus, when a certain anisotropic conductor 1 is pressed on the substrate 14, it is possible to prevent a problem that the heat is applied to the next adjacent anisotropic conductor 1. , Each anisotropic conductor 1 (1a, 1
b, 1c,...) can be adhered to a predetermined position of the substrate 14 in a good state.

In the first embodiment, as shown in FIG. 2, an adhesive tape 41 is used as the gap forming means 40 for peeling off the span cut portion SC to form a gap. I have. This adhesive tape 41 can be sufficiently used with a commercially available adhesive tape, its mechanism is simple, and it is not necessary to provide a large-scale mechanism. Can be stripped off.

In the gap forming means 40, the adhesive tape 41 is set on the adhesive tape supply reel 42, the leading end thereof is attached to the adhesive tape take-up reel 43, and a pressing plate 44 is provided in the middle thereof. Although the mechanism is such that the span cut portion SC is peeled off by pressing the adhesive tape 41 with the pressing plate 44, the present invention is not limited to such a mechanism. What is necessary is just a mechanism which can peel off SC. For example, an adhesive may be applied to the tip of the pressing plate 44, the span cut portion SC may be peeled off, and the peeled span cut portion SC may be removed from the pressing plate 44.

[Second Embodiment] FIG. 4 shows an anisotropic conductor sticking apparatus according to a second embodiment.
The second embodiment differs from the first embodiment only in the gap forming means 40, and is otherwise the same as the first embodiment. Therefore, the same parts are denoted by the same reference numerals. In the second embodiment, the gap forming means 40 has a configuration including an air injector 46 and an air injector driving unit 47 for controlling the driving of the air injector 46. Since the process of forming the span cut portion SC is the same as that of the first embodiment (see FIG. 2), the description of the formation of the span cut portion SC is omitted here.

FIG. 5 shows that the anisotropic conductor 1 existing in the span cut portion SC formed by the process described in the first embodiment is stripped off using an air injector 46 so as to be adjacent. This is for describing a process of forming a gap G between anisotropic conductors. As shown in FIGS. 5A and 5B, after the span cut portion SC is formed by the above-described cutter driving by the cutter driving unit 30, the span cut portion SC reaches the air injection position. Is detected by the air injector driving unit 47, the air injector driving unit 47 drives the air injector 46. As a result, as shown in FIG. 5C, the air 46a is vigorously blown from the air injector 46 to the span cut portion SC, and the span cut portion SC is peeled off from the tape 2.

As described above, in the second embodiment, first, the first cut L1 and the second cut L
After the cutout 2 is formed and the span cut portion SC is formed, an operation of stripping the span cut portion SC by blowing the air 46 a from the air injector 46 is performed. By performing such an operation in accordance with the flow of the tape 2,
The tape 2 to which the anisotropic conductor 1 is adhered is in a state as shown in FIG. That is, the anisotropic conductors 1 on the tape 2 are anisotropic conductors 1a, 1b, 1c,.
And between adjacent anisotropic conductors (between anisotropic conductor 1a and anisotropic conductor 1b, between anisotropic conductor 1b and anisotropic conductor 1c, etc.) In this state, a gap G of about 1 mm to 2 mm substantially corresponding to the span cut portion SC is formed.

The tape 2 in the state shown in FIG. 3 is supplied to the crimping tool 11 via the guide roller 5 in FIG. 1 as described in the first embodiment. The anisotropic conductors 1a, 1b, 1c,... Are pressed on the substrate 14 by the procedure described above. Also in this case, as in the first embodiment, since the gap G exists between the adjacent anisotropic conductors 1a, 1b, 1c,...
Can be made less likely to be affected by the heat applied to the anisotropic conductor 1a.

As described above, in the second embodiment, when cutting the anisotropic conductor 1 attached to the tape 2, the adjacent anisotropic conductors 1a, 1b, 1c,.
.. By forming a span cut portion SC of about 1 mm to 2 mm between the adjacent anisotropic conductors 1 by stripping the span cut portion SC by blowing air 46a.
A gap G of about 1 mm to 2 mm is formed between a, 1b, 1c,.

Thus, when a certain anisotropic conductor is pressed on a substrate, it is possible to prevent a problem that the heat is applied to the next adjacent anisotropic conductor and is added thereto. Each anisotropic conductor can be adhered to a predetermined position of the substrate in a good condition.

Further, in the second embodiment, as means for stripping the span cut portion SC, as shown in FIG. 5, the span cut portion SC is stripped using the air injector 46. It is not necessary to provide a large-scale mechanism, the cost as equipment can be kept low, and reliable stripping can be performed. Further, by blowing air, an effect that unnecessary dust and the like can be removed can also be obtained.

The air injector 46 used in the second embodiment can be used in the first embodiment. For example, after stripping off with an adhesive tape 41, the tape 2
If air is blown against the surface, it is possible to prevent peeling and to remove unnecessary dust and the like.

In the third embodiment, the span-cut portion SC is formed by the above-described process, and then the span-cut portion SC is peeled off by performing an operation of scraping the span-cut portion SC by the cutter 8. Thus, the gap G is formed. In the third embodiment, the cutter 8 and the cutter driving unit 30 that drives the cutter 8 also operate as a gap forming unit. The other parts are the same as those of the first or second embodiment, and the same parts are denoted by the same reference numerals. Less than,
The third embodiment will be described.

After the operation of cutting the first cut L1 has been performed, the cutter 8 is again pressed in the direction of the arrow x by the cutter driving unit 30 as described above with the tape 2 slightly advanced. An operation is performed to push the anisotropic conductor 1 completely. Thereby, as shown in FIG. 7B, the second cut L2 is cut in the anisotropic conductor 1, and the span cut portion SC is formed.

The operation up to this point is the same as that of the first embodiment or the second embodiment described above. However, when the second cut L2 is cut, the cutter driving section 30 turns the cutter 8
Is returned to the original position, and an operation is performed in which the cutter 8 is rotated in the direction indicated by the arrow y in the drawing while the second cut L2 is being cut (the state shown in FIG. 7B). As a result, the span cut portion SC can be lifted up by the blade 8a of the cutter 8, and the span cut portion S

As described above, according to the present invention,
As a cut for separating the anisotropic conductor adhered on the tape, two cuts are cut so that a predetermined space is formed between the adjacent anisotropic conductors, and a gap between the two cuts is formed. By stripping the extra anisotropic conductor part (span cut part) present in the tape from the tape, a gap is formed between the adjacent anisotropic conductors on the tape, and thereafter, A step of attaching an anisotropic conductor to each work at each cut is performed.

Thus, when a certain anisotropic conductor is pressed onto a work, it is possible to prevent interference between adjacent anisotropic conductors due to the above-mentioned gap. For this reason, it is possible to prevent, for example, a problem that the heat is applied to the adjacent anisotropic conductor, and to adhere each anisotropic conductor to a predetermined position of the substrate in a good state. it can. In addition, the means for forming two gaps and the means for forming a gap do not require a large-scale mechanism, so that the cost as equipment can be kept low, and furthermore, there is an extra space between the two gaps. The anisotropic conductor portion (span cut portion) can be reliably peeled off.
