【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圧加熱装置であって、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圧加熱装置に関<br>する。 The present invention relates to a pressure-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 performs mark registration, tacking Seki to <br> the upper and lower glass substrates was predetermined pressure-heating apparatus for curing 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治具にセットして加圧し、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。 Set to pressurized to jig with two pair of glass substrate after the bonding stacking plural sets, is intended to heat to cure the sealant put it in a heating furnace.
