【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【産業上の利用分野】本発明は液晶表示板用ガラス基板の加熱装置であって、詳しくはシール材を挟装した上下のガラス基板をマーク合わせを行って貼り合わせすると共に、仮止めした上下のガラス基板を所定のギャップまでシール材を加圧して硬化させる加熱装置に関する。 The present invention relates to a heating apparatus for a glass substrate for a liquid crystal display panel, the details will be bonded to the upper and lower glass substrates were sandwiched a sealing material by performing a mark alignment, temporarily fixed upper and lower the glass substrate for a given heating apparatus to cure the sealing material is pressurized to the gap.

【0002】 [0002]

【従来の技術】液晶表示板(LCD)は、透明導電性電極をコートした2枚のガラス基板間に数μmのスペーサを用いて所定の間隔に保ち、シール材で区画した内側の空間内に液晶を封入したもので、その2枚のガラス基板は位置合わせマークによって狂いなく貼り合わせられている。 A liquid crystal display panel (LCD) is maintained at a predetermined interval by using the number μm spacer between two glass substrates coated with transparent conductive electrodes, the space inside which is partitioned by the sealing member obtained by sealing a liquid crystal, two glass substrates that are stuck not have mad by the alignment mark.

【0003】ところで、液晶表示板を構成する2枚のガラス基板は、その一方のガラス基板の上にスペーサを散在し、他方のガラス基板の内面(一方のガラス基板と対向する面)には熱硬化性樹脂のシール材が取り付けられ、そうした上下のガラス基板が貼り合わせ装置によってマーク合わせを行って貼り合わせられると共に、上下のガラス基板が分離しないように仮止めされる。 Meanwhile, two glass substrates constituting the liquid crystal display plate is scattered spacers on the glass substrate of the other hand, on the inner surface of the other glass substrate (one glass substrate opposite to the surface) heat attached sealant curable resin, with are bonded by performing the mark registration by such upper and lower glass substrates of the bonded device, the upper and lower glass substrates are temporarily fixed so as not to separate. そして、貼り合わせ仮止めされた2枚1組のガラス基板は加圧、加熱処理して上下のガラス基板間のギャップをスペーサの粒径までシール材を加圧して該シール材を硬化させる。 The temporarily fixed the two pair of glass substrates pressure bonding, the gap between the glass substrates heat treatment to the upper and lower pressurizing the sealing material to a particle size of the spacer to cure the sealant.

【0004】その従来のシール材を硬化させる装置は、 [0004] device for curing the conventional sealing material,
貼り合わせを完了した2枚1組のガラス基板を複数組積み重ねると共に加圧して治具にセットし、それを加熱炉に入れてシール材を加熱し硬化させるものである。 Two pair of glass substrate after the bonding was set to pressurized jig with a plurality of sets stacked, is intended to heat to cure the sealant put it in a heating furnace.

【0005】 [0005]

【発明が解決しようとする課題】しかして、2枚1組のガラス基板を治具にセットして加熱炉に入れガラス基板を加熱した場合、加熱による熱伝導はガラス基板の周囲と中央部では温度差があり、熱膨張の差によって位置合わせされている上下のガラス基板が水平方向に移動して狂いが生じるといった問題点を有する。 [SUMMARY OF THE INVENTION] Thus, when the glass substrate was heated put in the heating furnace is set to a jig two pair of glass substrates, thermal conduction by heating at ambient and the central portion of the glass substrate There is a temperature difference, having a problem that the deviation occurs glass substrate top and bottom are aligned by the difference in thermal expansion is moved in the horizontal direction. これをなくす為に、加熱時間、加熱温度を調整しながら行っているが、 In order to eliminate this, the heating time, is performed while adjusting the heating temperature,
この場合は作業性が低下し、生産性に欠けるといった問題点を有する。 In this case, it reduces the workability, has a problem that lacks productivity.

【0006】又、貼り合わせ仮止めされている2枚1組のガラス基板は加熱によってシール材が溶融し、硬化されるが、その加熱時に2枚1組のガラス基板は加圧してガラス基板間のギャップを所定のギャップ(スペーサの粒径に相当する)にするが、その加圧はガラス基板全体に均一に作用させることが困難であり、したがってギャップを一定にすることが困難であるといった問題点を有する。 [0006] Also, bonded temporarily fixed by two pair of glass substrates has the sealing material is melted by heating, but is cured, between the glass substrates Part two pair of glass substrates during heating is pressurized Although the gap to a predetermined gap (corresponding to the particle size of the spacer), the pressure is difficult to act uniformly on the entire glass substrate, thus a problem that it is difficult to make constant the gap It has a point.

【0007】本発明は上述したような従来の技術が有する問題点に鑑みてなされたもので、その目的とするところは、ガラス基板の全面を均一に加熱できると共に、該ガラス基板の加圧も均一な分布荷重として作用させることができる加熱装置を提供することにある。 [0007] The present invention has been made in view of the problems of the prior art as described above, and an object, it is possible uniformly heat the entire surface of the glass substrate, even pressurization of the glass substrate to provide a heating apparatus which can be applied as a uniform distributed load.

【0008】 [0008]

【課題を解決するための手段】上記の目的を達成する為に本発明が講じた技術的手段は、二枚のガラス基板間に介在された熱硬化性樹脂からなるシール材を加熱、加圧して硬化させる加熱装置であって、位置合せし、且つ仮止めされた2枚1組のガラス基板を挟着する一方の固定定盤と、その固定定盤と対向して該定盤との間隔を広狭可変すると共に、加圧手段で加圧される可動定盤とから成り、その固定定盤と可動定盤は夫々ガラス基板と対向する面に周囲縁を残して凹部を穿設し、その凹部の開口を薄板で閉鎖すると共に、その薄板の周囲を前記周囲縁に接着固定し、且つ前記薄板の表面又は裏面に発熱体を取り付け、更に固定定盤と可動定盤の夫々の凹部には空気供給手段を連結装備したことを特徴とする。 Technical measure taken by the present invention for achieving the above object Means for Solving the Problems] is heated sealing material made of thermosetting resin interposed between two glass substrates, pressurized a heating apparatus for curing Te, aligning, and spacing of the temporarily fixed set of two one fixed platen glass substrate to pinched was a constant-board and opposite the fixed plate the well as wide or narrow variable consists of a movable platen to be pressurized by the pressurizing means, bored recesses leaving peripheral edge to the stationary platen and the movable platen are each glass substrate surface opposed to its the opening of the recess while closing a thin plate, the periphery of the thin plate is bonded and fixed to the peripheral edge, and a heating element attached to the front or back surface of the thin, further into the recess of each of the fixed platen and the movable platen characterized by being equipped with connecting air supply means. 上記の発熱体としては絶縁物からなる薄板に導電部材を取り付けた面状発熱体が効果的である The heating element of the a planar heating element is effectively attached to the conductive member in a thin plate made of an insulating material
