Description

この発明は、例えば、液晶用基板を貼り合わせるために加熱された液晶パネルやフラットパネルディスプレイ用板状被処理物（以下、これらを総称して表示用パネルという）を、常温まで冷却する際に用いられる冷却装置に関する。   For example, when cooling a liquid crystal panel heated to bond a liquid crystal substrate or a plate-like object for flat panel display (hereinafter collectively referred to as a display panel) to the room temperature, The present invention relates to a cooling device used.

熱処理装置は、表示用パネルを加熱する加熱装置と、熱処理後の表示用パネルを冷却する冷却装置とによって構成されている。加熱装置および冷却装置において、表示用パネルを支持するための支持具が使用される。   The heat treatment apparatus includes a heating device that heats the display panel and a cooling device that cools the display panel after the heat treatment. In the heating device and the cooling device, a support for supporting the display panel is used.

表示用パネルに傷を付けないようにするために、表示用パネルに対する支持具の接触面積をできるだけ小さくし、表示用パネルの複数か所をそれぞれピン等によって支持するようにしたものが知られている（例えば、特許文献１参照。）。   In order to prevent scratches on the display panel, it is known that the contact area of the support to the display panel is made as small as possible, and multiple places on the display panel are supported by pins, etc. (For example, refer to Patent Document 1).

ところが、このような支持の仕方をすると、表示用パネルの荷重がピン等に集中して作用することになり、このような荷重差が生じると、表示用パネルが撓むという問題がある。表示用パネルが撓むと、表示ムラが発生する。   However, with such a support method, the load of the display panel is concentrated on the pins and the like, and when such a load difference occurs, there is a problem that the display panel bends. When the display panel is bent, display unevenness occurs.

そこで、表示用パネルとの接触面積を大きくすることが考えられる。表示用パネルとの接触面積を大きくした冷却装置としては、図１０に示すように、複数の水平長尺状支持部材Ｓ（図示は１つのみ）が隣り合うもの同士所定間隔をおいて並列状に配置され、各支持部材の上面が平坦状支持面となされているように構成することができる。   Therefore, it is conceivable to increase the contact area with the display panel. As shown in FIG. 10, the cooling device having a large contact area with the display panel includes a plurality of horizontally long support members S (only one in the figure) adjacent to each other with a predetermined interval in parallel. The upper surface of each support member can be configured as a flat support surface.

このように支持部材によって表示用パネルを支持するようにすると、荷重集中による表示ムラの問題は解消される。ところが、図１１に示すように、表示用パネルおよび支持部材の接触部分（Ａ点）で熱移動が生じ、接触部分では急速に表示用パネルが冷却されるが、それ以外の部分（Ｂ点、Ｃ点）では冷却速度が低下する。このように、双方の部分の冷却カーブに温度差が生じると、荷重差の場合と同様に、表示ムラが同じ様に発生する。
特開２００２−１３０９５９号公報 When the display panel is supported by the support member in this way, the problem of display unevenness due to load concentration is solved. However, as shown in FIG. 11, heat transfer occurs at the contact portion (point A) of the display panel and the support member, and the display panel is rapidly cooled at the contact portion, but other portions (point B, At point C), the cooling rate decreases. As described above, when a temperature difference occurs between the cooling curves of both portions, display unevenness similarly occurs as in the case of the load difference.
JP 2002-130959 A

この発明の目的は、表示用パネル冷却時において、上記した荷重差および温度差のいずれによる表示ムラを発生させることのないように表示用パネルを支持する支持装置を備えた冷却装置を提供することにある。   An object of the present invention is to provide a cooling device provided with a support device that supports a display panel so that display unevenness due to any of the load difference and temperature difference described above does not occur when the display panel is cooled. It is in.

この発明による表示用パネル冷却装置は、冷却チャンバと、冷却チャンバ内に備えられかつ表示用パネルを多段に支持する支持装置とを備えており、支持装置が、支持部材を有しており、支持部材が、表示用パネルと部分的に接触してその表示用パネルを支持する支持部を有しており、支持部が、時間の経過とともに表示用パネルの異なる部分と接触するようになされているものである。   The display panel cooling device according to the present invention includes a cooling chamber and a support device that is provided in the cooling chamber and supports the display panel in multiple stages, and the support device includes a support member. The member has a support part that partially contacts the display panel and supports the display panel, and the support part comes into contact with different parts of the display panel over time. Is.

この発明による表示用パネル冷却装置では、表示用パネルおよび支持部材の接触部分が時間の経過とともに変化させられる。したがって、接触部分を通じて行われる、表示用パネルの熱移動のヵ所が変化するため、表示用パネルに温度差を発生させることを防止できる。   In the display panel cooling apparatus according to the present invention, the contact portion between the display panel and the support member is changed with time. Therefore, since the location of the heat transfer of the display panel performed through the contact portion changes, it is possible to prevent a temperature difference from being generated in the display panel.

さらに、支持部材が、水平状揺動軸に取付られており、支持部が、揺動軸の軸心を中心とする円弧状支持面によって形成されていると、揺動軸の回転にともない、表示用パネルを水平方向に移動させながら、支持面が表示用パネルの異なる部分と接触させられる。   Furthermore, when the support member is attached to the horizontal swing shaft and the support portion is formed by an arc-shaped support surface centered on the shaft center of the swing shaft, the rotation of the swing shaft causes The support surface is brought into contact with different portions of the display panel while moving the display panel in the horizontal direction.

また、支持部材が、揺動軸の半径方向に突出させられかつ先端を支持面とする垂直板によって構成されていると、シンプルな構造でもって、支持部材を構成することができる。   Further, when the support member is constituted by a vertical plate that protrudes in the radial direction of the swing shaft and has the tip as a support surface, the support member can be configured with a simple structure.

また、上記支持部材に代えて、支持部材が、揺動軸と同心状に配置されかつ外周面を支持面とする円筒状ローラによって構成されていてもよい。   Moreover, it may replace with the said support member and the support member may be comprised by the cylindrical roller which is arrange | positioned concentrically with a rocking | fluctuation shaft and uses an outer peripheral surface as a support surface.

さらなる支持部材として、支持部材が、水平方向に並んだ一対の昇降支持片によって構成されており、支持部が、支持片の上端に形成された水平平坦状支持面によって形成されていると、両支持片によって表示用パネルを支持するか、両支持片のいずれか一方によって表示用パネルを支持するかにより、表示用パネルおよび支持部材の接触部分が変化させられる。   As a further support member, the support member is composed of a pair of elevating support pieces arranged in the horizontal direction, and the support part is formed by a horizontal flat support surface formed at the upper end of the support piece. The contact portion between the display panel and the support member is changed depending on whether the display panel is supported by the support piece or the display panel is supported by either one of the two support pieces.

また、両支持片の昇降は、両支持片が同時に表示用パネルを支持しかつ両支持片が交互に表示用パネルを支持するように両支持片を昇降させる昇降手段によることが好ましい。   Further, the lifting and lowering of both support pieces is preferably performed by lifting means that lifts and lowers both support pieces so that both support pieces simultaneously support the display panel and both support pieces alternately support the display panel.

この発明による他の表示用パネル冷却装置は、冷却チャンバと、冷却チャンバ内に備えられかつ多段の棚を有するラックと、棚にそう方向に冷却風を送る送風手段とを備えており、各段の棚が、並列状に配置された複数の水平状揺動軸と、各揺動軸に長さ方向に間隔をおいて揺動軸の半径方向の同一方向に突出させられかつ揺動軸の軸心を中心とする円弧状支持面を先端に有する複数の垂直板状支持部材とを備えているものである。   Another display panel cooling device according to the present invention includes a cooling chamber, a rack provided in the cooling chamber and having a multi-stage shelf, and a blowing means for sending cooling air to the shelf in the direction of the shelf. A plurality of horizontal oscillating shafts arranged in parallel with each oscillating shaft and projecting in the same radial direction of the oscillating shaft at intervals in the lengthwise direction. And a plurality of vertical plate-like support members having an arc-shaped support surface centered on the axis at the tip.

この発明による冷却装置では、支持部材が送風の妨げにならないため、効率良く表示用パネルを冷却することができる。   In the cooling device according to the present invention, since the support member does not hinder the blowing, the display panel can be efficiently cooled.

この発明によるさらなる他の表示用パネル冷却装置は、冷却チャンバと、冷却チャンバ内に備えられかつ多段の棚を有するラックと、各段の棚にこれに直交する方向に冷却風を送る送風手段とを備えており、各段の棚が、並列状に配置された複数の水平状揺動軸と、各揺動軸と同心状に配置されかつ外周面を支持面とするローラとを備えているものである。   Still another display panel cooling apparatus according to the present invention includes a cooling chamber, a rack provided in the cooling chamber and having multi-stage shelves, and air blowing means for sending cooling air to the shelves of each stage in a direction perpendicular to the racks. Each of the shelves includes a plurality of horizontal swing shafts arranged in parallel and a roller that is arranged concentrically with each of the swing shafts and has an outer peripheral surface as a support surface. Is.

この発明による他のさらなる他の表示用パネル冷却装置では、各段の表示用パネルが個別に冷却風にさらされるため、極めて冷却効率がよい。   In still another display panel cooling apparatus according to the present invention, the display panels at the respective stages are individually exposed to cooling air, so that the cooling efficiency is extremely good.

上記冷却装置において、全ての揺動軸を同一方向に同一速度で、揺動手段によって揺動させることが好ましい。   In the cooling device, it is preferable that all the rocking shafts are rocked by the rocking means at the same speed in the same direction.

この発明によれば、表示用パネル冷却時において、上記した荷重差および温度差のいずれによる表示ムラをも発生させることを防止できる。   According to the present invention, it is possible to prevent display unevenness due to any of the load difference and the temperature difference described above when the display panel is cooled.

この発明の実施の形態を図面を参照しながらつぎに説明する。   Embodiments of the present invention will be described below with reference to the drawings.

以下の説明において、前後とは、図１を基準として、図１の左側を前、これと反対側を後といい、左右とは、後方より見て、その左右の側をそれぞれ左右というものとする。   In the following description, front and rear refer to FIG. 1 as a reference, the left side of FIG. 1 is the front, the opposite side is the rear, and the left and right are the left and right sides when viewed from the rear.

冷却チャンバ11は、略箱形状もので、後側壁21、前側壁22、左側壁23、右側壁24、頂壁25および底壁26よりなる。   The cooling chamber 11 has a substantially box shape and includes a rear side wall 21, a front side wall 22, a left side wall 23, a right side wall 24, a top wall 25 and a bottom wall 26.

後側壁21には入口31が、前側壁22には出口32がそれぞれ設けられている。入口31には入口シャッタ33が、出口32には出口シャッタ34がそれぞれ備えられている。   The rear side wall 21 is provided with an inlet 31, and the front side wall 22 is provided with an outlet 32. The entrance 31 is provided with an entrance shutter 33, and the exit 32 is provided with an exit shutter 34.

左側壁23に隣接して左垂直仕切板35によって区画された流出側通路36が形成されている。右側壁24に隣接して右垂直仕切板37によって区画された流入側通路38が形成されている。左垂直仕切板35および右垂直仕切板37は、詳しく図示しないが、適所に連通孔があけられている。左垂直仕切板35および右垂直仕切板37の下縁部は、水平仕切板39によって連絡されている。左垂直仕切板35に内外にまたがるように整流板41が設けられている。右垂直仕切板37の外側にはフィルタ42が装備されている。   An outflow side passage 36 defined by a left vertical partition plate 35 is formed adjacent to the left side wall 23. An inflow side passage 38 defined by a right vertical partition plate 37 is formed adjacent to the right side wall 24. Although the left vertical partition plate 35 and the right vertical partition plate 37 are not shown in detail, communication holes are formed at appropriate positions. The lower edge portions of the left vertical partition plate 35 and the right vertical partition plate 37 are connected by a horizontal partition plate 39. A rectifying plate 41 is provided to straddle the left vertical partition plate 35 in and out. A filter 42 is provided outside the right vertical partition plate 37.

流出側通路36に連通させられるように頂壁25左縁部には吸気口43が、流入側通路38に連通させられるように頂壁25右縁部には排気口44がそれぞれ設けられている。   An intake port 43 is provided at the left edge of the top wall 25 so as to communicate with the outflow side passage 36, and an exhaust port 44 is provided at the right edge of the top wall 25 so as to communicate with the inflow side passage 38. .

底壁26上面の左縁部に近接して水冷式クーラ45が備えられている。クーラ45の右側適所には複数の循環ファン46が備えられている。   A water-cooled cooler 45 is provided in the vicinity of the left edge of the upper surface of the bottom wall 26. A plurality of circulation fans 46 are provided on the right side of the cooler 45.

多段式ラック12は、冷却チャンバ11内において、左垂直仕切板35、右垂直仕切板37および水平仕切板39によって区画されたスペースに配置されている。   The multistage rack 12 is arranged in a space defined by the left vertical partition plate 35, the right vertical partition plate 37 and the horizontal partition plate 39 in the cooling chamber 11.

ラック12は、多段の、図示は、７段の棚51を有している。７段の棚51は、いずれも同一構造をもつものである。以下、１つの棚51についてのみ説明する。   The rack 12 has multi-stage shelves 51 in the figure. The seven shelves 51 have the same structure. Hereinafter, only one shelf 51 will be described.

棚51は、隣り合うもの同士間隔をおいて並列状に配置されている左右方向にのびた複数の、図示は、７つの水平状揺動軸61と、各揺動軸61に長さ方向に間隔をおいて取付られている複数の、図示は、５つの支持部材62とを備えている。５つの支持部材62は、同一構造のものである。以下、図４に詳細に示す１つの支持部材62について説明する。   There are a plurality of horizontal shelves 51 that are arranged in parallel and spaced apart from each other. In the figure, there are seven horizontal swing shafts 61, and each swing shaft 61 is spaced in the length direction. A plurality of support members 62 shown in the drawing are provided. The five support members 62 have the same structure. Hereinafter, one support member 62 shown in detail in FIG. 4 will be described.

支持部材62は、揺動軸61から半径方向に突出させられたものであって、揺動軸61に固定されているアーム63と、アーム63の先端に固定されている弓形状垂直板64とよりなる。垂直板64の先端に、表示用パネルＷの下面と接触させられた外向き円弧状支持面65が形成されている。支持面65のなす円弧の中心は、揺動軸61の揺動中心と一致させられている。また、全ての支持部材62は、同一方向に向けられている。   The support member 62 is projected from the swing shaft 61 in the radial direction, and includes an arm 63 fixed to the swing shaft 61 and an arcuate vertical plate 64 fixed to the tip of the arm 63. It becomes more. An outward arcuate support surface 65 that is brought into contact with the lower surface of the display panel W is formed at the tip of the vertical plate 64. The center of the arc formed by the support surface 65 is aligned with the swing center of the swing shaft 61. All the support members 62 are directed in the same direction.

冷却チャンバ11内に導入された空気をクーラ45によって冷却し、これを循環ファン46によって冷却チャンバ11内を循環させる。流入側通路38を上向きに流れた冷却風は、右垂直仕切板37の連通孔を通じてからラック12まで導かれる。ラック12内部を冷却風は、各段の棚51にそって流れ、左垂直仕切板35の連通孔を通じて流出側通路36に流出し、これを下向きに流れる。   The air introduced into the cooling chamber 11 is cooled by the cooler 45, and this is circulated through the cooling chamber 11 by the circulation fan 46. The cooling air flowing upward in the inflow side passage 38 is guided to the rack 12 through the communication hole of the right vertical partition plate 37. The cooling air flows inside the rack 12 along the shelves 51 of each stage, flows out to the outflow side passage 36 through the communication hole of the left vertical partition plate 35, and flows downward.

図示しない揺動手段により、全ての揺動軸61を同一方向に同一速度で揺動させると、各支持部材62の支持面65が表示用パネルＷとの接触部分を変えながら各支持部材62が揺動させられ、同時に、表示用パネルＷが前後方向に水平移動させられる。これにより、表示用パネルＷと支持面65との接触部分が移動していくため、熱移動が局部的に集中することが避けられる。   When all the swing shafts 61 are swung in the same direction and at the same speed by a swinging means (not shown), the support surface 65 of each support member 62 changes the contact portion with the display panel W, and each support member 62 At the same time, the display panel W is moved horizontally in the front-rear direction. Thereby, since the contact part of the display panel W and the support surface 65 moves, it can avoid that heat transfer concentrates locally.

図９に示すように、揺動軸61の揺動サイクルは、表示用パネルＷの冷却期間を通じて、３サイクル程度でよい。また、支持部材62の回転半径を１００ｍｍ程度とすると、表示用パネルのＷの水平方向の移動距離は１２０ｍｍ程度となる。   As shown in FIG. 9, the swing cycle of the swing shaft 61 may be about three cycles throughout the cooling period of the display panel W. If the rotation radius of the support member 62 is about 100 mm, the horizontal movement distance of the display panel W is about 120 mm.

図５および図６を参照すると、変形例による棚71は、隣り合うもの同士間隔をおいて並列状に配置されている左右方向にのびた４つの水平状揺動軸81と、各揺動軸81に取付られている揺動軸81と同数の支持部材82とを備えている。   Referring to FIGS. 5 and 6, the shelf 71 according to the modified example includes four horizontal swing shafts 81 extending in the left-right direction and arranged in parallel at intervals between adjacent ones, and each swing shaft 81. Are provided with the same number of support members 82 as the swing shaft 81 attached thereto.

各支持部材82は、対応する揺動軸81と同心状に配置されかつ外周面を支持面83とする円筒状ローラによって構成されている。   Each support member 82 is configured by a cylindrical roller that is arranged concentrically with the corresponding swinging shaft 81 and has an outer peripheral surface as a support surface 83.

この棚71を用いる場合、各支持部材82の近くでは、各支持部材82が表示用パネルＷの裏面を流れようとする冷却風の流れ妨げとなって、各支持部材82の近くでは流れのよどみができる可能性がある。これを防止するためには、各棚71毎にフィルタ84を配置し、各棚71に直交する方向に冷却風を流すことが好ましい。   When this shelf 71 is used, near each support member 82, each support member 82 hinders the flow of cooling air that tends to flow on the back surface of the display panel W, and the stagnation of the flow near each support member 82. May be possible. In order to prevent this, it is preferable to dispose a filter 84 for each shelf 71 and flow cooling air in a direction orthogonal to each shelf 71.

揺動軸81の揺動サイクルおよび熱移動の局部的集中防止作用は、先に説明した実施例による場合と同じである。   The rocking cycle of the rocking shaft 81 and the local concentration preventing action of heat transfer are the same as in the embodiment described above.

図７および図８にさらなる棚91の変形例が示されている。このさらなる変形例による棚91は、前後および左右方向に列をなして並びかつ隣り合うもの同士で接するように並んで対をなす複数対の支持片101、102を備えている。対をなす支持片101、102は、個別に昇降しうるようになっている。各支持片101、102の上端に水平平坦状支持面103、104が形成されている。   FIG. 7 and FIG. 8 show a further modification of the shelf 91. The shelf 91 according to this further modified example includes a plurality of pairs of support pieces 101 and 102 that are arranged side by side in the front-rear and left-right directions and that are adjacent to each other so as to be in contact with each other. The pair of support pieces 101 and 102 can be moved up and down individually. Horizontal flat support surfaces 103 and 104 are formed at the upper ends of the support pieces 101 and 102, respectively.

上段の棚91では対をなす支持片101、102の一方101が上昇させられ、その他方102は下降させられている。上昇させられている一方の支持片101の支持面103が表示用パネルＷの下面と接触させられている。上記の状態から、中段棚91で示すように、他方の支持片102を上昇させると、双方の支持片101、102の支持面103、104が同時に表示用パネルＷの下面と接触させられる。そして、下段の棚91で示すように、一方の支持片101を下降させると、今度は、他方の支持片102の支持面104だけが表示用パネルＷの下面と接触させられる。   In the upper shelf 91, one of the pair of support pieces 101, 102 is raised, and the other side 102 is lowered. The support surface 103 of the one support piece 101 that has been raised is brought into contact with the lower surface of the display panel W. From the above state, as shown by the middle shelf 91, when the other support piece 102 is raised, the support surfaces 103, 104 of both support pieces 101, 102 are simultaneously brought into contact with the lower surface of the display panel W. Then, as shown by the lower shelf 91, when one support piece 101 is lowered, only the support surface 104 of the other support piece 102 is brought into contact with the lower surface of the display panel W.

このように、表示用パネルＷに対して、一方の支持片101の支持面103が接触させられる場合、双方の支持片101、102の支持面103、104が接触させられる場合、他方の支持片102の支持面104が接触させられる場合において、表示用パネルＷおよび支持片101、102の接触部分が３通りに変化させられる。これにより、熱移動の集中が避けられる。   In this way, when the support surface 103 of one support piece 101 is brought into contact with the display panel W, when the support surfaces 103 and 104 of both support pieces 101 and 102 are brought into contact, the other support piece When the support surface 104 of 102 is brought into contact, the contact portions of the display panel W and the support pieces 101 and 102 are changed in three ways. This avoids concentration of heat transfer.

上記において、棚の段数、揺動軸の数、各揺動軸に取付られた支持部材の数等は、任意に選択可能である。   In the above, the number of shelves, the number of swing shafts, the number of support members attached to each swing shaft, and the like can be arbitrarily selected.

また、冷却チャンバは、表示用パネル入口および出口を備えているが、１つの開口を出入口とするようにしてもよい。   The cooling chamber includes a display panel inlet and outlet, but one opening may be used as an inlet / outlet.

また、円筒状ローラは、揺動軸のほぼ全長にわたって連続しているが、断続していもよい。   Further, the cylindrical roller is continuous over almost the entire length of the swing shaft, but may be intermittent.
