DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view showing a continuous bonding apparatus according to an embodiment of the present invention. As shown in FIG. 1, this continuous bonding apparatus has the following bonding means.
[0011]
<Paste means I>
First, the surface protection film 1a is peeled off by the winding roller 31 while continuously feeding the first single-sided adhesive film 1 from the feeding roller 30, and then the winding roller 36 from the adhesive-coated surface (back surface) of the film 1. The upper bonding roller 11 bonds the surface of the member A while peeling the release film 1b. Along with the film 1 with a single-sided adhesive, a protective film 3 for protecting the member A and a film-like adhesive (non-carrier film, hereinafter referred to as “NCF”), which will be described later, is provided on the upper laminating roller 11 from the feeding roller 35. It is sent and arranged on the surface of the film 1 attached to the member A. Examples of the protective film 3 include a polyethylene terephthalate film.
[0012]
In the case of the front plate for PDP, an anti-glare film or an antireflection film is used as the first single-sided adhesive film 1, and a film-like member such as an electromagnetic wave shielding film is used as the member A. The electromagnetic wave shielding film has flexibility in which a fine mesh pattern is printed on the entire surface of a transparent conductive film (for example, polyethylene terephthalate film). The roller 11 and the lower laminating roller 12 are sequentially supplied and conveyed. The upper bonding roller 11 forms a first bonding portion M together with the lower bonding roller 12. Both rollers 11 and 12 are rotated by a driving source such as a motor.
[0013]
<Bonding means II>
While continuously feeding out NCF 8 from the NCF feeding roller 32, the release film 8 b is peeled off from the back surface of the NCF 8 by the winding roller 33, and the back surface of the member A by the lower bonding roller 12 facing the upper bonding roller 11. Paste to. Bonding is performed simultaneously with the bonding of the film 1.
NCF8 is formed by forming an adhesive into a film and disposing release sheets 8a and 8b on both sides thereof. In the case of a PDP front plate, the NCF 8 is preferably transparent.
The member A is conveyed to the next bonding means III by the movement of the film 1 and NCF 8 with the films 1 and NCF 8 being bonded to both surfaces in the bonding means I and II, respectively.
[0014]
<Bonding means II>
While peeling the release film 8a from the surface of the NCF 8 affixed to the member A with the take-up roller 34, the member A is continuously fed to the second laminating portion N, and the upper laminating roller 13 The member A is bonded to the surface via NCF8. The 2nd bonding part N consists of the upper bonding roller 13 and the lower bonding roller 14, and these rollers 13 and 14 are driving sources, such as a motor, and the upper bonding roller 11 of the 1st bonding part M is. And it rotates at the same speed as the lower laminating roller 12. The member B is cut into a predetermined length in advance, and is sequentially supplied and conveyed between the upper bonding roller 13 and the lower bonding roller 14. The dimension of the member B is preferably the same as that of the member A.
[0015]
In the case of the front plate for PDP, the member B may be a film-like member similar to the member A, but a plate-like support such as a transparent support plate made of a transparent plastic plate such as a transparent glass plate or an acrylic resin plate. A board is illustrated. The support plate may be provided with a near infrared absorption function. That is, a transparent near-infrared absorbing film may be previously pasted on one side of a glass plate or a plastic plate. In the case of a plastic plate, it can be used as a near-infrared absorbing plate by itself.
The support plate has a thickness of 1 to 50 mm, preferably 1 to 10 mm, and the dimensions may be the same as those of the electromagnetic wave shielding film.
[0016]
<Bonding means IV>
The film 9 with the second single-sided adhesive is continuously fed from the feeding roller 37, and the film is applied to the back surface of the member B by the lower laminating roller 14 while peeling the release film 9a from the adhesive-coated surface by the winding roller 38. 9 is pasted.
[0017]
In the case of the front plate for PDP, an anti-glare film or an antireflection film is used as the second film with adhesive on one side 9. Although the film with the same function may be sufficient as the film 1 with a 1st single-sided adhesive and the film 9 with a 2nd single-sided adhesive, it is preferable to use a film with a different function. For example, when the film 1 is an antiglare film, the film 9 is preferably an antireflection film.
[0018]
In addition, the protective film 3 is wound and removed by the winding roller 39 from the surface of the bonded film that has come out of the second bonding portion N.
[0019]
2 (a) and 2 (b) show the bonding structure of the film immediately after passing through the first bonding portion M and the second bonding portion N, respectively. After removing the protective film 3, the bonding film which passed the 2nd bonding part N is cut by the predetermined dimension for every member A and B, or is sent to post processes, such as the following bonding means. . In the case of the front plate for PDP, it is manufactured by cutting the bonding film that has passed through the second bonding portion N for each of the members A and B. In FIG. 2, 15 and 16 have shown the adhesive layer which the film 1 with a 1st single-sided adhesive and the film 9 with a 2nd single-sided adhesive have, respectively.
[0020]
Thus, since each said bonding means I, II, III, and IV are installed in the conveyance direction of the member A, film bonding can be performed continuously and the film bonding operation is automated. It can save labor and improve productivity.
[0021]
In addition, a colorant can be contained in the pressure-sensitive adhesive or NCF 8 provided on one side of the films 1 and 9 so as to function as a toning layer for color matching with the PDP emission color. Alternatively, the toning film may be bonded using the same bonding means as described above. In the case of the front plate for PDP, only one of the films 1 and 9 may be used.
[0022]
In the above description, although the case where the continuous bonding apparatus of this invention is used for manufacture of the front plate for PDP was demonstrated, the continuous bonding apparatus of this invention is not limited only to this, Film bonding It can be used for various applications that require
[0023]
【The invention's effect】
As described above, according to the present invention, since it is possible to continuously bond three or more types of films, etc., it is possible to automate the bonding work and save labor, and to improve the productivity of the front plate for PDP and the like. Can be improved.
