2. Description of the Related Art A liquid crystal panel is one of the components constituting a liquid crystal display. As one of the methods for electrically connecting the terminals of the liquid crystal panel and the tabs forming the liquid crystal panel drive circuit, an anisotropic conductive film is interposed between the terminals of the liquid crystal panel and the tabs and heated. A method is known in which these are electrically connected by pressurizing.

This anisotropic conductive film is formed by thermocompressing a polymer layer in which conductive particles are uniformly dispersed in a synthetic resin to bring the conductive particles into contact with each other, and only in the thickness direction of the film. It has the property of being electrically conductive and showing insulating properties in the other directions. Then, such an anisotropic conductive film is usually covered with a release paper on one or both sides so as to be easily handled, so that two or three layers are formed.
It has a layered structure and is wound around a reel as an anisotropic conductive film tape (adhesive tape).

FIG. 7 is a sectional view of such an anisotropic conductive film tape. In the figure, reference numeral 1 indicates an anisotropic conductive film tape, and reference numeral 2 indicates an anisotropic conductive film as an adhesive formed by uniformly dispersing conductive particles in a synthetic resin. Reference numeral 3 denotes a release paper that covers one side of the anisotropic conductive film 2. The anisotropic conductive film tape 1 has a width of about 3 mm and a thickness of about 100 μm.

Conventionally, in order to connect the tabs of the liquid crystal panel drive circuit to the terminals of the liquid crystal panel via the anisotropic conductive film 2, first, the release paper 3 is peeled off to form a tape-shaped anisotropic conductive film. The film 2 is cut into a terminal length, for example, a length of about 35 mm to 70 mm, and the cut anisotropic conductive film pieces are overlapped with the terminal and pressed while being heated by a heating tool. Then, the tab is placed on the surface of the anisotropic conductive film 2, and the terminal, the anisotropic conductive film 2 and the tab are heated and pressed. Thereby, the anisotropic conductive film 2 is thermocompression-bonded to both the terminal and the tab, and the terminal and the tab are anisotropically conductive film 2.
Conducts through.

As a sticking device for sticking the anisotropic conductive film 2 to the terminals, for example, the applicant of the present invention has previously filed Japanese Patent Application No. 5-26.
There is one proposed by No. 2930. This conventional sticking device will be described with reference to FIG. FIG. 8 is a configuration diagram of a conventional sticking device, FIG. 8A shows a state in which a tip of an anisotropic conductive film from which release paper is peeled off is held by a chuck, and FIG.
Shows a state in which the tip of the anisotropic conductive film is adsorbed and held by a heating tool, FIG. 6C shows a state in which the anisotropic conductive film is cut, and FIG. It shows a state in which the anisotropic conductive film pieces are conveyed onto the terminals by a heating tool. In these figures, the same or equivalent members as those described in FIG. 7 are designated by the same reference numerals, and detailed description thereof will be omitted.

In these figures, reference numeral 4 is a supply reel around which the anisotropic conductive film tape 1 is wound, 5 is a release paper take-up reel for winding up the release paper 3, and 6 is a reel.
Indicates a chuck that holds the tip of the anisotropic conductive film 2 and pulls it, and 7 and 8 indicate guide reels. Also,
Reference numeral 9 denotes a fixed block that adsorbs and holds the tip of the anisotropic conductive film 2.

Reference numeral 10 denotes a heating tool for adsorbing and holding an anisotropic conductive film piece 2'obtained by cutting the anisotropic conductive film 2 and carrying it to a terminal (not shown) of the liquid crystal panel. The heating tool 10 is formed in a flat plate shape, has a heater (not shown) built therein, and has an adsorption surface for adsorbing and holding the anisotropic conductive film piece 2'on its lower surface. The heating tool is connected to a transfer device (not shown) to transfer the anisotropic conductive film piece 2'to the liquid crystal panel in a sucked and held state and press-contact the terminals of the liquid crystal panel. There is. The suction surface of the heating tool 10 is formed to have substantially the same length as the surface to which the terminal is attached.
Reference numeral 11 denotes a cutter for cutting the anisotropic conductive film 2.

As shown in FIG. 8A, this sticking device has a structure in which when the anisotropic conductive film tape 1 is pulled out from the reel 4, it is separated into an anisotropic conductive film 2 and a release paper 3. ing. The separated release paper 3 is taken up by the release paper take-up reel 5. Further, the anisotropic conductive film 2 is formed by the guide rollers 7 and 8
Is guided to the lower side of the reel 4 and extended horizontally from the guide roller 8 so that the tip end is held by the chuck 6. The anisotropic conductive film tape 1 is pulled out from the reel 4 by moving the chuck 6 to the right in the figure with the chuck 6 sandwiching the anisotropic conductive film.

In order to cut the anisotropic conductive film 2, first, as shown in FIG. 8B, the chuck 6 is cut to a predetermined length from the initial position shown in FIG. The anisotropic conductive film 2 is pulled out by moving it by a length corresponding to the range of the attachment surface. Next, the fixed block 9 is made to adsorb and hold the portion of the anisotropic conductive film 2 on the guide roller 8 side, and at the same time, the heating tool 10 is moved to the vicinity of the chuck 6 to cause the heating tool 10 to have an anisotropic conductive film. The tip of No. 2 is adsorbed and held.

After that, as shown in FIG. 8C, the fixed block 9 on the anisotropic conductive film 2 is cut by the cutter 11.
The portion between the heating tool 10 and the heating tool 10 is cut. The anisotropic conductive film 2 adsorbed and held by the heating tool 10 becomes an anisotropic conductive film piece 2 '. After cutting the anisotropic conductive film 2 in this way,
As shown in FIG. 8D, the anisotropic conductive film piece 2'is conveyed by the heating tool 10 and overlapped with the terminals of the liquid crystal panel (not shown).

After stacking the anisotropic conductive film piece 2'on the terminal, the anisotropic conductive film piece 2'is attached to the terminal by pressing the anisotropic conductive film piece 2'to the terminal side while heating it with the heating tool 10. To do.

[0013]

However, in the conventional pasting device having the above-mentioned structure, when the liquid crystal panel having different sticking surfaces of the terminals is used, the heating tool 10 is adapted to the terminals. There was a problem that it had to be exchanged for something that did. Since the heating tool 10 is formed in a flat plate shape, the length of the anisotropic conductive film piece 2'is set to the heating tool 1.
This is because the anisotropic conductive film piece 2'cannot be adsorbed and held unless it is aligned with the adsorption surface of 0 or the entire area of the anisotropic conductive film 2 cannot be heated and pressed in the attaching step.

Therefore, in the conventional pasting device, it is possible to use liquid crystal panels with different lengths of the pasted surfaces of the terminals.
It is necessary to prepare a plurality of types of heating tools 10 having different suction surface lengths, which increases the cost. Moreover, not only the labor for replacing the heating tool 10 is required, but also the apparatus must be stopped for a long time.

The present invention has been made in order to solve such a problem, and an object thereof is to make it possible to adhere the adherends (anisotropic conductive films) having different lengths with one heating tool. To do.

The length of the adhered material can be adjusted by partially cutting the adhered material upstream with respect to the application point with a cutter. That is, a value obtained by subtracting the total feed amount of the adhesive tape or the total movement of the adhered tape from the required length of the adherend (total length of the adherend surface) is the value of the tape between the cutter and the sticking point. When the length of the sticking material is equal to the length, the sticking material is cut with a cutter, and all the sticking materials on the downstream side of the cut portion are stuck, so that the sticking material can be stuck with the same length as the surface to be stuck.

After sticking, the sticking portion is sent so that the sticking surface always faces the anisotropic conductive film tape 1.

Next, the operation of the sticking device 21 thus constructed will be described. In order to attach the anisotropic conductive film 2 to the terminals of the liquid crystal panel 23 by the attaching device 21, first, as shown in FIG. 1, the feed guide 27, the guide roller 28,
The tension roller 29 and the heating tool 25 are moved to an initial position where they are largely separated upward from the support table 22. In this state, the liquid crystal panel 23 is placed and held on the support table 22.

The tip of the anisotropic conductive film 2 in the anisotropic conductive film tape 1 and the tip of the liquid crystal panel 23 to be attached (the upper surface of the terminal) in the longitudinal direction are the heating tools 25.
The drive roller 30, the take-up reel 32, and the support table 22 are driven so as to intersect a vertical line (not shown) passing through the axis of the. Next, as shown in FIG. 2, the feed guide 27, the guide roller 28, and the tension roller 29 are lowered to the vicinity of the support table 22, and together with this,
The heating tool 25 is lowered by the pressure head 35 so that the heating tool 25 presses the anisotropic conductive film tape 1 against the terminals of the liquid crystal panel 23.

This lowering step is performed with the protective film 36 attached to the heating tool 25. Further, the heater built in the heating tool 25 is energized in advance, and the heating tool 25 is heated to the attachment temperature of the anisotropic conductive film 2 before the lowering step.

After the anisotropic conductive film tape 1 is pressed against the terminals by the heating tool 25 as described above, the driving roller 30 and the take-up reel 32 are driven in the pulling direction of the anisotropic conductive film 1 and the supporting table is also provided. 22 is driven so that the liquid crystal panel 23 moves to the right in the figure. By doing so, as shown in FIG. 3, the anisotropic conductive film tape 1 and the liquid crystal panel 23 move in the same direction, the heating tool 25 rotates counterclockwise in the figure, and the anisotropic conductive film tape 1 moves. Anisotropic conductive film 2 rolling over
Attach to the terminal. That is, the point at which the heating tool 25 presses the anisotropic conductive film tape 1 against the terminals of the liquid crystal panel 23 (this point will be referred to as a sticking point in the following, which is indicated by the symbol A in FIG. 3) is relative to the liquid crystal panel 23. Figure 3
It is attached while moving to the left side of.

At this time, the release paper 3 of the anisotropic conductive film tape 1 is pulled upward by the guide roller 28 after being pressed by the heating tool 25, and is sequentially peeled off from the front end side of the anisotropic conductive film 2. Therefore, only the anisotropic conductive film 2 remains on the terminals. The release paper 3 that has been peeled off is guided by the guide roller 28, the tension roller 29, and the drive roller 30.
It is wound on a take-up reel 32 while being attached to the pinch roller 31.

The length of the anisotropic conductive film 2 attached to the terminal is
The anisotropic conductive film 2 is adjusted by partially cutting it with a cutter 26 in advance on the upstream side of the attachment point A. That is, a value obtained by subtracting the total feed amount of the anisotropic conductive film tape 1 or the total movement amount of the support table 22 (liquid crystal panel 23) from the required length of the anisotropic conductive film 2 (total length of the adhered surface). Is equal to the tape length between the cutter and the sticking point A, the tape pulling device 24 and the support table 22 are stopped, and as shown in FIG. The anisotropic conductive film 2 is attached to the anisotropic conductive film tape 1 by partially cutting off the anisotropic conductive film 2.
To form a void 1a where no After that, the feeding of the anisotropic conductive film tape 1 and the movement of the support table 22 are restarted, and the anisotropic conductive film 2 on the downstream side of the space 1a is restarted.
Attach all to the terminals. Thereby, the anisotropic conductive film 2
Can be attached so that it has the same length as the surface to which the terminal is attached.

After sticking the anisotropic conductive film 2 for a required length in this way, the tape pulling device 24 and the support table 22 are stopped, and the heating tool 25 is moved by the pressing head 35 as shown in FIG. To raise. At this time, the heating tool 25 is separated upward from the tension roller 29. In this state, the anisotropic conductive film 2 is all attached to the terminals, but the release paper 3 is attached to the anisotropic conductive film 2.

Next, in order to separate the release paper 3 from the anisotropic conductive film 2, as shown in FIG.
8 and the tension roller 29 are moved horizontally in the vicinity of the feed guide 27, in other words, to the upstream side in the pulling direction of the anisotropic conductive film tape 1. By this movement, all of the release paper 3 is pulled upward by the guide roller 28 and peeled off. After peeling off the release paper 3 in this way, as shown in FIG. 6, the guide roller 28 and the tension roller 29 are returned to their original positions on the right side in the drawing, and further, these rollers 28, 29 and the feed guide 27 are It is raised from the support table 22 to an initial position that is upwardly spaced. After that, the liquid crystal panel 23 is removed from the support table 22, and the support table 22 and the heating tool 25 are returned to the initial position. By repeating the above-described operation, the anisotropic conductive film 2 can be sequentially attached to the liquid crystal panel 23.

Therefore, according to this sticking device 21,
The anisotropic conductive film 2 is partially cut off by the cutter 26 according to the total feeding amount of the anisotropic conductive film tape 1 or the total moving amount of the support table 22 (liquid crystal panel 23), so that the anisotropic conductive film Since the length of the membrane 2 can be changed,
Even if the length of the surface to be adhered changes, the anisotropic conductive film 2 can be adhered to the entire area of the surface to be adhered with one heating tool 25.

Further, since the sticking device 21 is constructed so that the guide roller 28 and the tension roller 29 can be moved to the upstream side in the pulling direction of the anisotropic conductive film tape 1, after sticking the anisotropic conductive film 2. By moving the guide roller 28 and the tension roller 29 as described above, the release paper 3 can be gradually peeled from the tip end side of the portion to be attached to the anisotropic conductive film 2.

Other Embodiments When the anisotropic conductive film tape 1 is pressed against the terminals of the liquid crystal panel 23 by the heating roller 25, the feeding guide 27, the guide roller 28, the tension roller 29 and the heating tool 25 are used as described above. In addition to taking the form of raising and lowering with respect to the support table 22, it is also possible to take the following two forms. (1) The heating tool 25 is constructed so as not to move vertically, and the feed guide 27 and the guide roller 2
8, the tension roller 29 and the support table 22 are configured to be movable up and down, and the anisotropic conductive film tape 1 is pressed against the heating tool 25 from below. In this form, in order to peel off the release paper 3 after sticking, the guide roller 28 and the tension roller 29 may be moved horizontally as in the forms shown in FIGS. 1 to 6, or these rollers 28, 29 and the feed guide 27 may be moved relative to the support table 22 so as to be separated upward. (2) The feeding guide 27, the guide roller 28, and the tension roller 29 are configured so as not to move in the vertical direction, and the heating tool 25 and the support table 22 are configured to be movable up and down, and the anisotropic conductive film tape 1 is heated. 25 and the liquid crystal panel 23 on the support table 22 are pressed from both sides in the vertical direction. In taking this form, the release paper 3 can be peeled off after the sticking, by lowering the support table 22 relative to the guide roller 28 and the tension roller 29 without horizontally moving them.

In the above-described embodiment, an example in which the anisotropic conductive film 2 is attached to the terminals of the liquid crystal panel 23 as an adhesive is described, but the present invention is not limited to this, and various adhesives can be applied. It can also be applied to.
