Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anisotropic conductive tape sticking apparatus and an anisotropic conductive tape sticking method.

[0002]

2. Description of the Related Art In recent years, TCP (Tape
To attach electronic parts such as Carrier Package)
An anisotropic conductive tape is used. Briefly explaining this attaching step, a leader tape (also referred to as a separator tape) having an anisotropic conductive tape attached on its lower surface is fed out from a tape supply section, and only the anisotropic conductive tape is cut into a predetermined length. To do. Then, the cut anisotropic conductive tape is placed on the substrate and pressed by a crimping tool to adhere it to the substrate, and then the leader tape is peeled off from the anisotropic conductive tape adhered to the substrate. is there.

In the conventional anisotropic conductive tape sticking apparatus, the following two methods are known as methods for cutting only the anisotropic conductive tape into a predetermined length.

The first one is shown in FIG. 36 (process explanatory view showing a first example of a conventional anisotropic conductive tape cutting method), and FIG.
As shown in FIG. 3, the anisotropic conductive tape 2 attached to the lower surface of the leader tape 1 is cut into only one place while feeding the leader tape 1 in the feed direction M to the cutter 3. However, in this way, as shown in FIG. 37, when the anisotropic conductive tape 2 is pressed against the substrate 4 by the crimping tool 5, the position of the crimping tool 5 is located on the upstream side in the feeding direction M even if it is slightly smaller than the notch. If it is deviated, the anisotropic conductive tape 2 on the upstream side in the feeding direction M rather than the notch may also be pressed, and the extra anisotropic conductive tape 2 may be erroneously pressed onto the substrate 4. Therefore, it is necessary to control the feeding accuracy of the leader tape 1 and the positional accuracy of the crimping tool 5 extremely strictly.

Next, as shown in FIG. 38 to FIG. 40 (process explanatory view showing a second example of the conventional anisotropic conductive tape cutting method), the second type is different by using a burning tool 6. This is a method of burning out a part of the anisotropic conductive tape 2. That is, the debris removing tape 7 facing the anisotropic conductive tape 2
39 is supported on the cushion body 8, and the high temperature burning tool 6 is pressed against the anisotropic conductive tape 2 via the leader tape 1 as shown in FIG. The removed portion is printed on the dust removing tape 7 to remove it from the leader tape 1.
However, by doing so, the anisotropic conductive tape 2
There is a possibility that the end portion 2b of the battery may be deteriorated by heating and the electronic parts may not be mounted in the subsequent process, and this end portion 2b (which should be originally attached to the substrate 4) is as shown by the broken line in FIG. In some cases, it is erroneously attached to the residue removing tape 7 and cannot be attached to the substrate 4.

[0006]

As described above, in the conventional anisotropic conductive tape sticking apparatus, the process of cutting the anisotropic conductive tape is unstable and it is difficult to obtain a good sticking result. There was a point.

Therefore, it is an object of the present invention to provide an anisotropic conductive tape sticking apparatus and an anisotropic conductive tape sticking method which can smoothly cut an anisotropic conductive tape.

[0008]

SUMMARY OF THE INVENTION An anisotropic conductive tape sticking apparatus according to the present invention is a tape supply section for supplying a leader tape having an anisotropic conductive tape stuck on its lower surface, and a tape supply section for supplying the leader tape. A tape transport unit that transports the leader tape in the feed direction, a tape cutting unit that cuts only the anisotropic conductive tape to a predetermined length in the feed direction, and a substrate to which the anisotropic conductive tape is attached are positioned. A board positioning portion and a tape crimping portion for crimping the anisotropic conductive tape cut to a predetermined length to the substrate are provided, and the tape cutting portion is separated from the anisotropic conductive tape by a predetermined distance in the feeding direction. It has a notch forming part for making a notch and a removing means for removing the anisotropic conductive tape between the notches from the leader tape.

[0009]

According to the above construction, the notch forming portion makes two notches at a predetermined distance in the feeding direction in the anisotropic conductive tape, and the anisotropic conductive tape between these notches has the removing means. Removed by. That is, a blank area is formed on the anisotropic conductive tape. Thereafter, the anisotropic conductive tape whose tape crimping portion is located downstream of the blank area in the feeding direction is crimped to the substrate. Therefore, even if the feeding accuracy of the leader tape is not extremely high, the anisotropic conductive tape, which should not be pasted, will not be pressure-bonded to the substrate due to the existence of the blank area, and the pasting operation can be performed smoothly. You can In addition, since the anisotropic conductive tape is not thermally treated, it is possible to avoid alteration of the end portion.

Then, as shown in FIG. 31, the gripping roller 53 and the gripping roller 54 are moved to the upstream side in the feeding direction M while the leader tape peeling state is maintained, and the leader tape 1 is peeled from the first strip 107. . At this time, the feed rollers 58 and 5 of the leader tape feeding unit 24
The rotation of 9 is prohibited so that the leader tape 1 collected by the leader tape collecting unit 25 is not pulled back.

Then, as shown in FIG. 32, when the peeling of the leader tape 1 is completed, the cylinder 28 is driven to drive the cylinder of FIG.
The member surrounded by the chain line 2 is raised to return the gripping roller 53 and the gripping roller 54 from the rotated state to the original state. Next in FIG.
