CONSTITUTION: While one roller 11 is brought into contact with the front surface of the separator 2, this roller is moved together with another roller 12 to a cutting point 13 side and the separator is peeled at the time of peeling the separator 2 from the cut anisotropic conductive film 1a stuck to the substrate 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separator peeling method for sticking an anisotropic conductive film to various substrates such as liquid crystal substrates.

[0002]

2. Description of the Related Art It has been widely known that an anisotropic conductive film is attached to various substrates such as liquid crystal substrates. that time,
For example, as disclosed in JP-A-2-293721, a tape having a two-layer structure of an anisotropic conductive film and a separator is used, and after the anisotropic conductive film of this tape is attached to a substrate, By nipping the separator with a pair of rollers arranged on the upper and lower surfaces of the separator, by moving both rollers together from one side to the other side where the anisotropic conductive film and the substrate are attached. The separator is peeled off from the anisotropic conductive film.

[0003]

However, according to this known peeling method, the pair of rollers are disposed above the tape portion adhered to the substrate, that is, the substrate, the anisotropic conductive film and the separator are separated from each other. When the separator is peeled off from the anisotropic conductive film attached to the substrate, since the layered portion (hereinafter referred to as the attachment point) is moved above the upper surface of the separator. However, it has a drawback that static electricity is generated by the impact.

The present invention has been invented in view of such drawbacks, and one of the pair of rollers, which is arranged on the upper surface side of the separator, is brought into contact with the upper surface of the separator. It has been found that the roller, which is arranged on the lower surface side of the separator, is moved so as not to come into contact with the anisotropic conductive film, whereby the roller can be peeled off without generating static electricity.

[0005]

That is, according to the present invention, a method of separating a separator when an anisotropic conductive film is attached is a method for removing the anisotropy of a tape having a two-layer structure of an anisotropic conductive film and a separator. After sticking the conductive film to the substrate, both rollers are nipped with the pair of rollers arranged on the upper and lower surfaces of the separator while nipping the separator to remove the anisotropic conductive film and the substrate. In the separator peeling method of peeling the separator from the anisotropic conductive film by moving together from one side to the other side, the one of the rollers arranged on the upper surface side of the separator is attached to the sticker. The roller which is arranged on the lower surface side of the separator is moved while being brought into contact with the upper surface of the separator attached to the anisotropic conductive film, and the roller is placed in contact with the anisotropic conductive film. Is characterized in that the moving so as not.

It is preferable that the roller disposed on the upper surface side of the separator is a rotating roller and the roller disposed on the lower surface side of the separator is a non-rotatable roller.

EXAMPLE In FIG. 1, a double-layered tape 3 having an anisotropic conductive film 1 and a separator 2 adhered thereto is intermittently transferred from the left side on the tape supply side to the right side on the tape winding side,
When the fixed length is transferred, only the anisotropic conductive film 1 is cut by the cutter 4. The cutter 4 is mounted so that it can move up and down and can move in the front-rear direction together with the guide 5 as described later. Further, the guide claws 7 and 8 and the heating tool 9 are also mounted so as to be able to move up and down, as described later.

Subsequently, as shown in FIG. 2, with the cutter 4 and the guide 5 retracted, the heating tool 9 moves downward to apply the tape 3 to the substrate 10.
Press on. Therefore, the cut anisotropic conductive film 1a having a certain length is attached to the substrate 10. Before the heating tool 9 moves downward, the cut anisotropic conductive film 1a and the substrate 10 are separated by a predetermined distance. The substrate 10 is placed on a movable table (not shown), and the substrate 10 is moved in a predetermined direction (for example, X,
By the movement control in the Y, Z, and θ-axis directions, it is positioned at the position to be attached.

Next, when the sticking is completed, as shown in FIG. 3, the heating tool 9 is moved to the upper origin position and the pair of rollers 11 and 12 are moved to the sticking position. Come on. In addition, one roller 11
Is located on the upper surface side of the separator 2 and the other roller 12 is located on the lower surface side.
1, 12 are mounted so that they can move together in the front-rear direction, as will be described later. The roller 11 has an outer diameter larger than the outer diameter of the other roller 12 and is mounted so as to be freely rotatable.

Subsequently, as shown in FIG. 4, both rollers 11 and 12 are brought close to each other to lightly hold (or nip) the separator 2, that is, one roller 11 is cut anisotropy. The upper surface of the separator 2 that is attached to the conductive film 1a is lightly contacted, and the other roller 12 is lightly contacted with the lower surface of the separator 2.

Then, the rollers 11 and 12 are moved to the left together with the distance therebetween kept. that time,
One roller 11 is rotated (to the left in this example) in the forward direction (in the direction of the arrow in the drawing), and is always on the upper surface of the separator 2 attached to the cut anisotropic conductive film 1a. Move while touching. Therefore, the separator 2 can be peeled off from the cut anisotropic conductive film 1a little by little without giving an impact, and on the basis of this, the generation of static electricity can be effectively prevented.

The other roller 12 is the separator 2
Are moved so as not to come into contact with the peeled cut anisotropic conductive film 1a. When the rollers 11 and 12 move forward, the guide claw 7 moves upward. Therefore, the other roller 12 can be moved to the left. In addition,
The separator 2 is pulled to the arrow side (winding side) in the figure.

FIG. 5 shows a state in which the rollers 11 and 12 are peeled to the cut portion 13 in this way. Subsequently, both rollers 11.1
2 is moved to the retracted position on the front side, and the guide claw 8
Is moved upward to the same level as the guide claw 7. This state is shown in FIG.

Next, the movable table on which the substrate 10 is placed is controlled to move, and the substrate 10 is moved to the next attachment position.
Is positioned, and in parallel with this, the tape 3 is intermittently transferred from the left side on the tape supply side to the right side on the tape winding side, and a fixed length thereof is transferred.

Then, the cutter 4 and the guide 5 are moved together from the retracted position on the front side to the tape 3.
That is, as shown in FIG.
Is moved above the separator 2 of the tape 3, and the cutter 4 is moved below the anisotropic conductive film 1. Then, after that, the cutter 4 is moved upward to cut only the anisotropic conductive film 1. The guide 5 prevents the tape 3 from being pushed upward and deformed when the cutter 4 cuts the anisotropic conductive film 1.

Thereafter, the cut anisotropic conductive film 1a can be attached to the substrate 10 one after another through the same steps as described above. 7 shows a perspective view of the sticking head portion, the heating tool 9 is vertically moved by the air cylinder 15, and the guide claws 7, 8 are also vertically moved by the air cylinders 16, 17. It Also,
The tape 3 is delivered from the supply reel 18, and the separator 2 from which the anisotropic conductive film 1 is removed is the take-up reel 19.
It is wound up. A plurality of guide rollers 20 are mounted at predetermined locations as needed.

Further, FIG. 8 shows a mounting mode of the cutter 4 and the guide 5, etc., but the cutter 4 and the guide 5 are mounted by the Y table 21 so as to be movable in the Y-axis direction, and The cutter 4 is mounted by the air cylinder 22 so as to be movable in the Z-axis direction, that is, movable up and down. Although the Y table 21 is mounted on the X table 23, a second Y table 24 is further mounted on the table 23, and both rollers 11 and 12 are mounted on the table 24.

More specifically, one roller 11 is mounted so as to be freely rotatable by a bearing 25 mounted on the second Y table 24. On the other hand, the other roller 12 is mounted on the air cylinder 26 mounted on the second Y table 24. Therefore, the roller 12 cannot rotate but can be moved toward and away from the roller 11 by the air cylinder 26.

Therefore, by controlling the movement of the X-table 23, the cutter 4, the guide 5 and the rollers 11 and 12 are positioned at predetermined positions in the X-axis direction with respect to the sticking head portion shown in FIG. It is possible to move both rollers 11 and 12 from the position shown in FIG. 4 to the position shown in FIG. 5, and in addition, by controlling the movement of both Y tables 21 and 24, such heads can be moved. The cutter 4, the guide 5, and the rollers 11 and 12 can be positioned at a predetermined position in the Y-axis direction with respect to the section.

Although one embodiment according to the present invention has been described above, in the present invention, both rollers 11, 12 may be so-called free rollers that can freely rotate. However, it suffices for the roller 12 to be composed of a so-called fixed roller that cannot rotate than the free roller.
The ratio between the outer diameter of one roller 11 and the outer diameter of the other roller 12 is appropriately selected. Also, X table 2
The base 27 to which 3 is attached may be attached so as to be able to move up and down.
