Description

本発明は、液晶表示パネルやプラズマ表示パネルなどの構成部材であるガラス基板や半導体リードフレームあるいはその他の金属板や合成樹脂板などの各種板状部材の熱処理に使用される加熱装置に関する。   The present invention relates to a heating apparatus used for heat treatment of various plate-like members such as glass substrates, semiconductor lead frames, other metal plates, and synthetic resin plates, which are constituent members of liquid crystal display panels and plasma display panels.

液晶表示パネルなどの構成部材であるガラス基板を熱処理する装置としては、従来、加熱気体循環方式のクリーンオーブンが使用されている(例えば、特許文献1参照。)。このクリーンオーブンは、ガラス基板などの被熱処理物を恒温槽内に収容し、この恒温槽内においてファンによって循環する加熱気体を用いて被加熱物の熱処理を行うものである。   As a device for heat-treating a glass substrate which is a constituent member such as a liquid crystal display panel, a heated gas circulation type clean oven has been conventionally used (for example, see Patent Document 1). This clean oven accommodates an object to be heat treated such as a glass substrate in a thermostat and heat-treats the object to be heated using a heated gas circulated by a fan in the thermostat.

しかしながら、加熱気体循環方式のクリーンオーブンの場合、ガラス基板などの被加熱物を多段状に収容する構造を採用しやすいので、スペース効率に優れている反面、加熱温度分布を均一化することが困難であり、加熱気体の攪拌によりクリーン度が悪化する可能性が高い。また、被加熱物が比較的軽量である場合、加熱気体の循環対流によって被加熱物が所定の位置から移動することがある。   However, in the case of a heated gas circulation type clean oven, it is easy to adopt a structure that accommodates a heated object such as a glass substrate in multiple stages, so it is excellent in space efficiency, but it is difficult to make the heating temperature distribution uniform. There is a high possibility that the cleanliness will deteriorate due to the stirring of the heated gas. When the object to be heated is relatively light, the object to be heated may move from a predetermined position by circulating convection of the heated gas.

このような問題を解決するため、内部に発熱体を有する放熱板の両面に遠赤外線放射セラミックスの薄層が被覆され、この放熱板の加熱によって両面から遠赤外線を放射する両面加熱式の遠赤外線パネルヒータからなる多数の棚状ヒータが、炉本体内に上下方向に一定間隔で多段配置され、これらの棚状ヒータの間に形成される各空間部分をそれぞれ乾燥室とした加熱炉が開発されている(例えば、特許文献2参照。)。   In order to solve such a problem, both sides of a heat sink having a heating element inside are coated with a thin layer of far infrared radiation ceramics, and far-infrared infrared radiation that emits far infrared rays from both sides by heating this heat sink. A large number of shelf heaters composed of panel heaters are arranged in multiple stages in the furnace body at regular intervals in the vertical direction, and a heating furnace has been developed in which each space formed between these shelf heaters is a drying chamber. (For example, refer to Patent Document 2).

特許文献2記載の加熱炉の場合、両面加熱式の遠赤外線パネルヒータからなる多数の棚状ヒータが配置されているため、これらの棚状ヒータの間に形成される各空間部(乾燥室)を効率的に加熱することができる点では優れている。   In the case of the heating furnace described in Patent Document 2, a large number of shelf heaters composed of double-sided heating type far-infrared panel heaters are arranged, and thus each space portion (drying chamber) formed between these shelf heaters. Is superior in that it can be heated efficiently.

しかしながら、この加熱炉においては、上下方向に配置された多数の棚状ヒータから発される熱は、加熱炉内を上昇して炉内の天壁寄りの領域に集まる傾向があるため、炉内上部領域の温度は、炉内下部領域の温度より高くなっており、このような炉内上部領域と炉内下部領域との間の温度差をなくすことは極めて困難である。   However, in this heating furnace, heat generated from a large number of shelf heaters arranged in the vertical direction tends to rise in the heating furnace and collect in a region near the top wall in the furnace. The temperature in the upper region is higher than the temperature in the lower region in the furnace, and it is extremely difficult to eliminate such a temperature difference between the upper region in the furnace and the lower region in the furnace.

そこで、本出願人は、温度分布の均一性及びクリーン度の安定性に優れた加熱装置を提案している(例えば、特許文献3参照。)。この加熱装置は、断熱材で囲まれた空間内に距離を隔てて対向配置された複数の加熱用壁体と、加熱用壁体に設けられた発熱手段と、加熱用壁体の間に距離を隔てて配置された複数の伝熱壁体と、伝熱用壁体の間に棚状に配置された複数の熱放射部材と、上下方向に隣り合う熱放射部材の間に設けられた被加熱物の収容スペースとを備えている。   Therefore, the present applicant has proposed a heating device that is excellent in uniformity of temperature distribution and stability of cleanliness (see, for example, Patent Document 3). This heating device has a distance between a plurality of heating walls disposed opposite to each other in a space surrounded by a heat insulating material, heating means provided on the heating wall, and the heating wall. A plurality of heat transfer walls disposed across the heat transfer wall, a plurality of heat radiation members disposed in a shelf shape between the heat transfer walls, and a heat radiation member provided between the heat radiation members adjacent in the vertical direction. And a storage space for a heated object.

特許文献3記載の加熱装置は、温度分布の均一性及びクリーン度の安定性に優れているが、収容スペース内に収容することのできる被加熱物のサイズが限定されるので、所定サイズから外れた被加熱物は収容スペースに収容困難であるのが実状である。   Although the heating device described in Patent Document 3 is excellent in uniformity of temperature distribution and stability of cleanliness, the size of an object to be heated that can be accommodated in the accommodation space is limited. In fact, it is difficult to accommodate the object to be heated in the accommodation space.

即ち、特許文献3記載の加熱装置において加熱処理可能な被加熱物のサイズ(幅、厚さ)は、複数の加熱用壁体の間に距離を隔てて配置された複数の伝熱壁体に形成された水平方向の保持溝の対向間隔及び垂直方向の溝幅よって定まるので、幅方向のサイズが前記対向間隔未満若しくはこれを超える被加熱物、及び、厚さが前記垂直方向の溝幅を超える被加熱物は収容スペース内に収容することができない。   That is, the size (width, thickness) of the object to be heated in the heating device described in Patent Document 3 is set to a plurality of heat transfer wall bodies arranged at a distance between the plurality of heating wall bodies. Since it is determined by the facing interval and the vertical groove width of the formed horizontal holding grooves, the object to be heated whose width direction size is less than or exceeding the facing interval, and the thickness is the vertical groove width. The object to be heated cannot be accommodated in the accommodation space.

従って、加熱処理の対象である被加熱物のサイズ(幅、厚さ)が変更された場合、複数の伝熱壁体の配置間隔を変更して保持溝の対向間隔を調整したり、保持溝の垂直方向の溝幅を変更したりする必要がある。このため、被加熱物のサイズ変更に迅速に対応することが困難である。   Therefore, when the size (width, thickness) of the object to be heated is changed, the arrangement interval of the plurality of heat transfer wall bodies is changed to adjust the opposing interval of the holding grooves, or the holding groove It is necessary to change the vertical groove width. For this reason, it is difficult to respond quickly to the size change of the object to be heated.

そこで、本発明が解決しようとする課題は、温度分布の均一性及びクリーン度の安定性に優れ、少なくとも被加熱物の幅方向サイズの変更に容易に対応することのできる加熱装置を提供することにある。   Therefore, the problem to be solved by the present invention is to provide a heating device that is excellent in uniformity of temperature distribution and stability of cleanliness, and can easily cope with at least a change in the width direction size of an object to be heated. It is in.

本発明の加熱装置は、距離を隔てて対向配置された複数の加熱用壁体と、前記加熱用壁体に設けられた発熱手段と、複数の前記加熱用壁体の対向領域に上下方向に距離を隔てて棚状に配置された複数の熱放射部材と、複数の前記熱放射部材の間に設けられた被加熱物の収容スペースと、前記収容スペース内に収容される被加熱物を所定姿勢に保持可能であって前記被加熱物の保持範囲を変更可能な保持手段と、を備え

前記拡縮機構は、
前記収容スペースの左側の正面、背面からそれぞれ突出した前記左側の支持バー材の正面部、背面部にそれぞれ取り付けられた左正面側の支柱、左背面側の支柱と、
前記収容スペースの右側の正面、背面からそれぞれ突出した前記右側の支持バー材の正面部、背面部にそれぞれ取り付けられた右正面側の支柱、右背面側の支柱と、
前記左正面側の支柱及び前記左背面側の支柱と、前記右正面側の支柱及び前記右背面側の支柱と、の間隔を拡縮させる移動機構であることを特徴とする。
The heating apparatus according to the present invention includes a plurality of heating walls arranged opposite to each other at a distance, a heat generating unit provided on the heating wall, and a vertical region in a facing region of the plurality of heating walls. A plurality of heat radiating members arranged in a shelf shape at a distance, a space to be heated to be provided between the plurality of heat radiating members, and a heated object to be accommodated in the accommodation space are predetermined. Holding means that can be held in a posture and change a holding range of the object to be heated ; and
As the holding means, a plurality of support members on which the object to be heated can be placed, and an expansion / contraction mechanism capable of changing the interval between the support members,
The support member is
A left side support bar material and a right side support bar material arranged in a state of horizontally penetrating the left and right two regions separated in the width direction in the accommodation space, respectively,
The expansion / contraction mechanism is

It is a moving mechanism that expands or contracts the distance between the left front column and the left back column, the right front column and the right back column .

このような構成とすれば、被加熱物の収容スペースは左右に加熱用壁体が配置され、上下に熱放射部材が配置された構造となり、それぞれの収容スペース内は、発熱手段の熱によって昇温した左右の加熱用壁体から放射される熱と、これらの加熱用壁体からの熱伝導により発熱する熱放射部材から上下に放射される熱とによって加熱されるため、それぞれの収容スペース内はむらなく均等に加熱され、温度分布の均一性に優れたものとなる。   With such a configuration, the space for storing the object to be heated has a structure in which heating walls are arranged on the left and right sides and heat radiating members are arranged on the upper and lower sides, and the inside of each accommodation space is raised by the heat of the heating means. Heat is radiated from the heated left and right heating walls and heat radiated up and down from the heat radiating member that generates heat by heat conduction from these heating walls. Is evenly heated and has excellent uniformity of temperature distribution.

発熱手段は加熱用壁体のみに設けられており、各収容スペースは、それぞれの左右に位置する加熱用壁体と、上下に位置する熱放射部材によって区画されているため、各収容スペース内における温度分布の均一性も優れているだけでなく、熱気の上昇に起因する上部空間における熱蓄積現象および過熱現象が発生しない。また、ファンによって加熱気体を攪拌したり、循環させたりすることもないので、クリーン度の安定性も優れており、気体流によって被加熱物が移動することもない。   The heating means is provided only in the heating wall, and each storage space is partitioned by the heating wall positioned on the left and right and the heat radiation member positioned on the top and bottom, Not only is the temperature distribution uniform, it does not cause heat accumulation and overheating in the upper space due to the rise of hot air. Further, since the heated gas is not stirred or circulated by the fan, the stability of the cleanliness is excellent, and the heated object is not moved by the gas flow.

また、保持手段による被加熱物の保持範囲は、被加熱物の幅に応じて変更することができるため、少なくとも被加熱物の幅方向サイズの変更に容易に対応することができる。   In addition, since the holding range of the object to be heated by the holding unit can be changed according to the width of the object to be heated, it is possible to easily cope with at least a change in the width direction size of the object to be heated.

ここで、前記保持手段として、被加熱物を載置可能な複数の支持部材と、前記支持部材の間隔を変更可能な拡縮機構と、を設けることが望ましい。このような構成とすれば、被加熱物は支持部材により下支え状態で保持することが可能となるので、被加熱物の厚さが変更された場合でも容易に対応することができる。   Here, as the holding means, it is desirable to provide a plurality of support members on which an object to be heated can be placed and an expansion / contraction mechanism capable of changing the interval between the support members. With such a configuration, the object to be heated can be held in a supported state by the support member, so that even when the thickness of the object to be heated is changed, it can be easily handled.

前記左正面側の支柱及び前記左背面側の支柱と、前記右正面側の支柱及び前記右背面側の支柱と、の間隔を拡縮させる移動機構である。このような構成とすれば、移動機構によって複数の支柱の間隔を拡縮するだけで、支持バー材の間隔を変更することが可能となるため、比較的簡素な構造でありながら、操作性及び安定性に優れた調整手段を形成することができる。

It is possible to form an adjusting means having excellent properties.

さらに、複数の加熱用壁体の対向領域外から前記保持手段の保持範囲を変更可能な操作機構を設けることもできる。このような構成とすれば、被加熱物の収容スペースの外側から保持手段の保持領域を変更することが可能となるため、操作性がさらに向上する。   Furthermore, it is possible to provide an operation mechanism capable of changing the holding range of the holding means from the outside of the facing region of the plurality of heating walls. With such a configuration, it becomes possible to change the holding area of the holding means from the outside of the accommodation space for the object to be heated, so that the operability is further improved.

With such a configuration, it becomes possible to replace the air in the accommodation space with an inert gas or a specific gas, so that the object to be heated is prevented from being oxidized by the inert gas, or a reaction with the specific gas is used. Then, a surface treatment can be applied to the object to be heated.

Thereafter, in each storage space 14, the left and right edges of the article 13 to be heated are placed on the support bars 17L and 17R, respectively, and part of the left and right edges are respectively engaged with the locking grooves 15Lt and 16Lt and the locking grooves. When accommodated in 15Rt and 16Rt, the setting of the object to be heated 13 is completed, so that when the electric heater 11 is energized, heat treatment can be performed according to a predetermined program.

被加熱物13の収容スペース14は左右に加熱用壁体10L,10Rが配置され、上下に熱放射部材12が配置され、それぞれの収容スペース14内は、電気ヒータ11の熱によって昇温した左右の加熱用壁体10L,10Rから放射される熱と、これらの加熱用壁体からの熱伝導により発熱する熱放射部材12から上下に放射される熱とによって加熱されるため、それぞれの収容スペース14内はむらなく均等に加熱され、加熱装置100全体における温度分布の均一性も良好である。   Heating walls 10L and 10R are disposed on the left and right sides of the accommodation space 14 of the article 13 to be heated, and the heat radiating members 12 are disposed on the upper and lower sides. Are heated by the heat radiated from the heating walls 10L and 10R and the heat radiated from the heat radiating member 12 that generates heat by heat conduction from the heating walls. The inside of 14 is heated evenly, and the uniformity of the temperature distribution in the entire heating device 100 is also good.

電気ヒータ11は加熱用壁体10L,10Rのみに設けられており、各収容スペース14は、それぞれの左右に位置する加熱用壁体10L,10Rと、上下に位置する熱放射部材12によって区画されているため、各収容スペース14内における温度分布の均一性も優れており、熱気の上昇に起因する上部空間における熱蓄積現象及び過熱現象が発生しない。また、ファンによって加熱気体を攪拌したり、循環させたりすることもないので、クリーン度の安定性も優れており、気体流によって被加熱物が移動することもない。   The electric heater 11 is provided only in the heating wall bodies 10L and 10R, and each accommodation space 14 is partitioned by the heating wall bodies 10L and 10R positioned on the left and right sides and the heat radiation member 12 positioned on the top and bottom. Therefore, the uniformity of the temperature distribution in each storage space 14 is also excellent, and the heat accumulation phenomenon and the overheating phenomenon in the upper space due to the rise of hot air do not occur. Further, since the heated gas is not stirred or circulated by the fan, the stability of the cleanliness is excellent, and the heated object is not moved by the gas flow.

また、支持バー材17L,17Rによる被加熱物13の幅方向Wの保持範囲は、被加熱物13の横幅に応じて変更することができるため、少なくとも被加熱物13の幅方向サイズの変更に容易に対応することができる。なお、被加熱物13の厚さが過大である場合、その左右側縁を係止溝15Lt,16Lt及び係止溝15Rt,16Rt内に収容することなく、支持バー17L,17R上に載置しただけの状態で加熱処理することもできる。   Moreover, since the holding range of the to-be-heated object 13 in the width direction W by the support bar members 17L and 17R can be changed according to the lateral width of the to-be-heated object 13, at least for changing the size in the width direction of the to-be-heated object 13. It can be easily handled. When the thickness of the article to be heated 13 is excessive, the left and right edges are placed on the support bars 17L and 17R without being accommodated in the locking grooves 15Lt and 16Lt and the locking grooves 15Rt and 16Rt.
