Abstract

PURPOSE:To carry out the bonding of a glass substrate with an adhesive layer having uniform thickness, by supplying an adhesive to the surface of a glass substrate placed on a table, placing another glass substrate on the adhesive and rotating the table to effect the spreading of the adhesive layer by the centrifugal force. CONSTITUTION:A glass substrate 22 to be bonded is placed on a spinner head 21 (a substrate table) facing the bonding surface upward. An adhesive 23 is supplied to the surface of the substrate 22 e.g. by dripping, and another glass substrate 24 is placed on the substrate 22 facing the bonding surface downward. The spinner head 21 is rotated at a rotational speed of preferably 1,000-3,000rpm to spread the adhesive 23 radially by the centrifugal force. A uniform adhesive layer can be formed by this procedure to give a bonded glass substrate having high flatness. The staining of the outer circumference of the substrate with the adhesive can be prevented and the bonding cost can be reduced remarkably.

Description

１３を圧縮し延伸する方法である。One glass substrate 12 to be adhered is placed on a surface plate 11 with good flatness, adhesive 13 is dripped onto the upper surface of the glass substrate 12, the other glass substrate 14 is placed, and a flat surface is placed on top of it. This is a method of placing another surface plate 15 with good strength and applying pressure to compress and stretch the adhesive 13.

場合、接着後のガラス基板の平面度が損なわれる場合が
多かった。更に加圧力が偏ると接着剤が均一に拡がらず
、接着剤厚みムラが生じる等の欠点も有った。In this method, the adhesive that protrudes from at least one of the glass substrates 12 or 14 to be applied rises to the edge of the glass substrate 12 or 14 and adheres to the outer periphery of the substrate, so it is necessary to remove this excess adhesive. It took a lot of time to remove it. Furthermore, if there is a convex object such as dust between the surface plates 11 to 15 to be compressed and the glass substrates 12 to 14, this area will be locally pressurized, resulting in uneven adhesive layer thickness and When the substrate is a thin glass sheet with a thickness of 1 mm or less, the flatness of the glass substrate after bonding is often impaired. Furthermore, if the applied pressure is uneven, the adhesive will not spread uniformly, resulting in uneven thickness of the adhesive.

本発明の目的は薄板ガラスの貼り合せプロセスに於いて
上記欠点を解決し、接着剤層厚みを一定にし、接着後の
ガラス基板の平面度を良好に保ちしかも余剰な接着剤の
除去が容易な量産的な製造方法を提供するものである。The purpose of the present invention is to solve the above-mentioned drawbacks in the process of bonding thin glass sheets, to make the thickness of the adhesive layer constant, to maintain good flatness of the glass substrate after bonding, and to easily remove excess adhesive. This provides a mass-production manufacturing method.

〔問題点を解決するための手段〕[Means for solving problems]

上記の目的を達成させるために、本発明は次のようなプ
ロセスとなっている。In order to achieve the above object, the present invention has the following process.

複数枚のガラス基板を接着剤を介して貼り合せ接着固定

供給した後膣接着剤上に被着される他の一方のガラス基

剤層を遠心力によって拡げることを特徴とする。In a manufacturing method in which multiple glass substrates are bonded and fixed using an adhesive, one of the glass substrates to be adhered is placed on a rotatable base, and an adhesive is supplied onto the glass substrate. After that, the other glass substrate to be adhered is placed on the vaginal adhesive and the base is rotated to spread the adhesive layer by centrifugal force.

〔作用〕[Effect]

このプロセスで接着されたガラス基板は、回転により生

で拡がった接着剤は、ガラス基板の端面に留まらず遠心
力によって外に飛ばされるので余剰な接着剤を後で除去
する手間が不用となる。In glass substrates bonded by this process, the adhesive tends to spread radially from the center due to the centrifugal force generated by rotation, so if a constant rotation speed and rotation time are given, the adhesive layer thickness will be approximately constant. Further, the adhesive that has spread to the end surface of the glass substrate to be adhered does not stay on the end surface of the glass substrate but is blown out by centrifugal force, so that there is no need to remove excess adhesive later.

〔実施例〕〔Example〕

述する。Hereinafter, an embodiment in which the present invention is used for bonding a color filter substrate and a display segment electrode substrate in the manufacturing process of a display panel for a liquid crystal color television will be described in detail with reference to FIG.

Reference numeral 24 denotes another glass substrate to be adhered, and electrodes for driving liquid crystal are formed on the surface opposite to the surface to be adhered. 21 is a spinner head as a rotatable base.

次に接着プロセスを順を追って説明する。Next, the adhesion process will be explained step by step.

良い。The one glass substrate 22 is placed on the spinner head 21 shown in FIG. 1 with the surface to be adhered facing up. In this case, it does not matter which side of the pair of glass substrates 22 and 24 comes first. Alternatively, the lower surface of the glass substrate 22 to be placed first may be vacuum-adsorbed.

次に該ガラス基板２２上に接着剤２３を滴下等の方法で
供給する。接着剤としては紫外線硬化型接着剤を用いた

いことは云うまでもない。Next, the adhesive 23 is supplied onto the glass substrate 22 by a method such as dropping. Although an ultraviolet curable adhesive was used as the adhesive, it goes without saying that other thermosetting adhesives may be used as the adhesive.

接着剤はほぼ中心に滴下するのが好ましい。Preferably, the adhesive is dropped approximately in the center.

次に被着する他の一方のガラス基板２４を被着面な下に
して前記ガラス基板２２の上に重ねる様に載せる。Next, the other glass substrate 24 to be adhered is placed on top of the glass substrate 22 with the surface to be adhered facing downward.

A range of 000 rpm to 3000 rpm is suitable. The rotation time was in the range of 30 seconds to 100 seconds.

去することもこのプロセスの優れた効果の一つであり。Note that the rotation speed and rotation time are factors that determine the thickness g of the adhesive layer together with the viscosity of the adhesive, so they should be set according to the purpose. In this example, when using the adhesive/agent 1, for example, Toshi's ultraviolet curable adhesive Photorec A206 (viscosity approximately 50 cps), the rotation speed was 200 rpm.
With a rotation time of 80 seconds, two sheets of 6-inch square thin glass sheets could be bonded together with good flatness. At this time, a uniform adhesive layer thickness of approximately 15 μm was achieved. Since an ultraviolet curable adhesive was used as the adhesive, after the above bonding process, the adhesive surface was irradiated with ultraviolet rays having a main wavelength of 355 nm for about 3 minutes to cure and complete the bonding process. Of the 231.5 cc of adhesive dropped in this process, the amount actually required to be effective as an adhesive layer is approximately 20% Q, 3
cc, and the excess 80% of the adhesive is on the glass substrate 22.
24, it was thrown off by centrifugal force and discarded. In fact, removing excess adhesive from the adhered substrate in this way is one of the excellent effects of this process.

従来の前記加圧接着法等での余剰のハミ出した接着剤を
後処理により除去する多大な労力の削減が出来た。It is possible to reduce the great amount of labor involved in removing excess adhesive that has spilled out in the conventional pressure bonding method or the like through post-processing.

Although the process of bonding the color filter substrate and display segment electrode substrate is shown, the present invention is not limited to this, and the present technology can be used in a wide range of industrial fields of communication, such as the production of solar cells.

Moreover, the fact that there is no excess adhesive adhering to the outer periphery of the substrate to be adhered, and that it was achieved in a short process time has made it possible to significantly reduce adhesive costs and create inexpensive LCD color TV display panels. It is now possible to provide the following.
