Description

本発明は、被加熱体の所望の被加熱領域を精度よく加熱可能な加熱盤、加熱装置及び加熱方法に関する。 The present invention relates to a heating plate, a heating device, and a heating method capable of accurately heating a desired heated area of a heated object.

伝熱部１３ａは、ヒータ１３ｂを覆って接触するように設けられ、被加熱体と接触する接触部１３ｅにおいてヒータ１３ｂの熱を被加熱体Ｍに伝え、所望の被加熱領域を加熱する。加熱装置１をヒートシールに用いる場合には、加圧も行い、所定の幅、長さで熱圧着する。 The heat transfer section 13a is provided so as to cover and contact the heater 13b, and heats the heater 13b to the heated body M at the contact section 13e that contacts the heated body, thereby heating a desired heated area. When the heating device 1 is used for heat sealing, pressurization is also performed and thermocompression bonding is performed with a predetermined width and length.

伝熱部１３ａは断熱材１３ｃを介して固定部１３ｄに取り付けられている。これにより、ヒータ１３ｂの熱は固定部１３ｄ側に散逸することがなく、効率よく接触部１３ｅに伝えられる。 The heat transfer part 13a is attached to the fixed part 13d via a heat insulating material 13c. Thereby, the heat of the heater 13b is not dissipated to the fixed part 13d side, but is efficiently transmitted to the contact part 13e.

伝熱部１３ａは、加熱用途・目的に応じて各種形状を採用することができる。本実施形態では、伝熱部１３ａは、断面の外形形状が凸字状に形成されており、伝熱部１３ａの接触部１３ｅと保持部材１２の表面１２ａの端部との距離が、伝熱部１３ａの底部と保持部材１２との水平方向の距離より広くなるように離間されている。そして、接触部１３ｅがヒータ１３ｂを内蔵する部分よりも幅が狭くなるように形成されている。また、接触部１３ｅは、保持部材１２の表面よりも外方に突出して設けられており、補助加熱部材１５は伝熱部１３ａの一部を覆うように表面部１５ａが延長されて形成されている。伝熱部１３ａをこのように構成すると、被加熱体Ｍと接触する表面で加熱部材１３と保持部材１２との隙間（水平方向の距離）を大きくできる。この隙間量を調節することで加熱部材１３から保持部材１２への輻射による熱伝達を適度に調整することができる。これにより、被加熱部材Ｍの性状や加熱条件に合わせて隙間を設定することでより高精度な加熱温度の制御が可能となる。 The heat transfer section 13a can adopt various shapes depending on the heating application and purpose. In the present embodiment, the heat transfer section 13a has a convex outer shape in cross section, and the distance between the contact portion 13e of the heat transfer section 13a and the end of the surface 12a of the holding member 12 is the heat transfer section. The bottom portion of the portion 13a and the holding member 12 are spaced apart so as to be wider than the horizontal distance. And the contact part 13e is formed so that a width | variety may become narrower than the part which incorporates the heater 13b. The contact portion 13e is provided to protrude outward from the surface of the holding member 12, and the auxiliary heating member 15 is formed by extending the surface portion 15a so as to cover a part of the heat transfer portion 13a. Yes. If the heat transfer part 13a is configured in this way, the gap (horizontal distance) between the heating member 13 and the holding member 12 can be increased on the surface in contact with the heated body M. By adjusting the gap amount, heat transfer due to radiation from the heating member 13 to the holding member 12 can be appropriately adjusted. Thereby, it is possible to control the heating temperature with higher accuracy by setting the gap according to the properties of the member to be heated M and the heating conditions.

加熱部材１３は、複数の支持部材１４により、保持部材１２と離間するように支持されている。本実施形態では、矩形状の加熱部材１３の各辺の中央と角部の８箇所が支持部材１４により固定されている。 The heating member 13 is supported by a plurality of support members 14 so as to be separated from the holding member 12. In this embodiment, the center of each side of the rectangular heating member 13 and the eight corners are fixed by the support member 14.

支持部材１４は、台座１１に形成されたねじ部１１ａにねじ込み可能に形成された筒状のアジャスタボルト１４ａと、アジャスタボルト１４ａに挿通され、加熱部材１３をアジャスタボルト１４ａに固定する固定ボルト１４ｂと、を備えている。支持部材１４は、断熱部材１６に形成された孔部を貫通して配置される。 The support member 14 has a cylindrical adjuster bolt 14a formed so as to be screwable into a screw portion 11a formed on the base 11, and a fixing bolt 14b that is inserted into the adjuster bolt 14a and fixes the heating member 13 to the adjuster bolt 14a. It is equipped with. The support member 14 is disposed through the hole formed in the heat insulating member 16.

加熱部材１３は、固定ボルト１４ｂを加熱部材１３の固定部１３ｄに締め付けて、アジャスタボルト１４ａの端部を固定ボルト１４ｂと加熱部材１３とにより挟み込むことによりアジャスタボルト１４ａに固定される。 The heating member 13 is fixed to the adjuster bolt 14 a by fastening the fixing bolt 14 b to the fixing portion 13 d of the heating member 13 and sandwiching the end of the adjuster bolt 14 a between the fixing bolt 14 b and the heating member 13.

アジャスタボルト１４ａを保持部材１２に対して上下させることにより、加熱部材１３を保持部材１２に対して上下させることができる。これにより、保持部材１２に対する加熱部材１３の位置関係や、加熱部材１３と加熱部材２３との平行度などを調整することができる。また、小面積で加熱部材１３を支持するため、熱の散逸を小さくすることができる。 The heating member 13 can be moved up and down with respect to the holding member 12 by moving the adjuster bolt 14 a up and down with respect to the holding member 12. Thereby, the positional relationship of the heating member 13 with respect to the holding member 12, the parallelism between the heating member 13 and the heating member 23, and the like can be adjusted. Further, since the heating member 13 is supported with a small area, heat dissipation can be reduced.

The 2nd holding member 17 which consists of these is provided. The second holding member 17 holds the heated body M apart from the contact portion 13e of the heating member 13 by placing the heated body M on the protruding member 17b. In this embodiment, it is provided in a total of six places, three places on the left and right.

保持部材１２の上面には、被加熱体Ｍの位置決めを行うための位置決め部材である位置決めピン１８が設けられている。位置決めピン１８は、被加熱体Ｍの形状に合わせて配置され、保持部材１２の上面から突出して設けられている。本実施形態では、１２箇所に設けられている。 On the upper surface of the holding member 12, positioning pins 18 that are positioning members for positioning the heated object M are provided. The positioning pins 18 are arranged according to the shape of the heated body M and are provided so as to protrude from the upper surface of the holding member 12. In this embodiment, it is provided at 12 locations.

図６に示すように、加熱盤２０は、位置決め手段２８の形状以外は加熱盤１０と同一構造に形成されている。以下の説明において、台座２１は台座１１に、保持部材２２は保持部材１２に、表面２２ａは表面１２ａに、ヒータ２２ｂはヒータ１２ｂに、熱電対２２ｃは熱電対１２ｃに、加熱部材２３は加熱部材１３に、接触部２３ｅは接触部１３ｅに、熱電対２３ｆは熱電対１３ｆに、支持部材２４は支持部材１４に、補助加熱部材２５は補助加熱部材１５に、断熱部材２６は断熱部材１６に、第２保持部材２７は第２保持部材１７に、突出部材２７ｂは突出部材１７ｂに、それぞれ対応する。位置決め手段２８は位置決めピン１８の形状に対応した凹部として形成されている。 As shown in FIG. 6, the heating board 20 is formed in the same structure as the heating board 10 except for the shape of the positioning means 28. In the following description, the base 21 is the base 11, the holding member 22 is the holding member 12, the surface 22a is the front surface 12a, the heater 22b is the heater 12b, the thermocouple 22c is the thermocouple 12c, and the heating member 23 is the heating member. 13, the contact portion 23e is the contact portion 13e, the thermocouple 23f is the thermocouple 13f, the support member 24 is the support member 14, the auxiliary heating member 25 is the auxiliary heating member 15, the heat insulating member 26 is the heat insulating member 16, The second holding member 27 corresponds to the second holding member 17, and the protruding member 27b corresponds to the protruding member 17b. The positioning means 28 is formed as a recess corresponding to the shape of the positioning pin 18.

加熱装置１において、加熱盤１０と加熱盤２０とは、加熱部材１３と加熱部材２３とが対向するように配置されている。以下に、２枚のシート状部材Ｍ１、Ｍ２からなる被加熱体Ｍを熱圧着してヒートシールする場合を例に、加熱装置１を用いた被加熱体Ｍの加熱方法を、図７−９を参照して説明する。なお、図７−９においては、駆動機構３３、荷重検出手段３４、制御装置４０は省略している。 In the heating device 1, the heating panel 10 and the heating panel 20 are arranged so that the heating member 13 and the heating member 23 face each other. Below, the heating method of the to-be-heated body M using the heating apparatus 1 is demonstrated to the example of the case where the to-be-heated body M which consists of two sheet-like members M1 and M2 is thermocompression-bonded, and FIG. Will be described with reference to FIG. 7-9, the drive mechanism 33, the load detection means 34, and the control apparatus 40 are abbreviate | omitted.

まず、制御装置４０により、加熱盤１０の加熱部材１３、保持部材１２、補助加熱部材１５及び加熱盤２０の加熱部材２３、保持部材２２、補助加熱部材２５をそれぞれ所定の設定温度で温調する。ここで、加熱部材１３及び加熱部材２３は、ヒートシールを行うための温度に設定される。また、保持部材１２及び補助加熱部材１５の表面温度は、加熱部材１３の表面温度よりも低くなるように設定、制御され、保持部材２２及び補助加熱部材２５の表面温度は、加熱部材２３の表面温度よりも低くなるように設定、制御される。 First, the control device 40 controls the temperature of the heating member 13, the holding member 12, the auxiliary heating member 15, and the heating member 23, the holding member 22, and the auxiliary heating member 25 of the heating panel 20 at predetermined set temperatures. . Here, the heating member 13 and the heating member 23 are set to a temperature for performing heat sealing. Further, the surface temperatures of the holding member 12 and the auxiliary heating member 15 are set and controlled to be lower than the surface temperature of the heating member 13, and the surface temperatures of the holding member 22 and the auxiliary heating member 25 are the surface of the heating member 23. It is set and controlled to be lower than the temperature.

次に、図７（Ａ）に示すように、被加熱体Ｍを保持部材１２上に配置する。ここで、被加熱体Ｍは２枚のシート状の部材が重ね合わされた状態で、位置決めピン１８で位置合わせされ、突出部材１７ｂの上に載置される。ここで、被加熱体Ｍはまだ加熱部材１３と接触していない。加熱部材１３は熱圧着を行うシートＭ２の外周部に面するように配置されている。 Next, as illustrated in FIG. 7A, the heated object M is disposed on the holding member 12. Here, the heated body M is aligned with the positioning pin 18 in a state where the two sheet-like members are overlapped, and is placed on the protruding member 17b. Here, the heated object M has not yet contacted the heating member 13. The heating member 13 is disposed so as to face the outer peripheral portion of the sheet M2 that performs thermocompression bonding.

続いて、駆動手段３０により加熱盤１０を加熱盤２０に向かって移動させる。加熱盤２０は図７（Ｂ）に示すように、最初に突出部材１７ｂ及び突出部材２７ｂにおいて被加熱体Ｍと接触し、被加熱体Ｍは対向する突出部材１７ｂと突出部材２７ｂとにより上下から挟み込まれた状態となる。このとき、被加熱体Ｍは加熱部材２３とは接触していない。 Subsequently, the heating panel 10 is moved toward the heating panel 20 by the driving means 30. As shown in FIG. 7B, the heating panel 20 first contacts the heated body M at the protruding member 17b and the protruding member 27b, and the heated body M is viewed from above and below by the opposing protruding member 17b and protruding member 27b. It will be in the state where it was pinched. At this time, the heated object M is not in contact with the heating member 23.

更に加熱盤１０を上方に移動させると、図８（Ａ）に示すように、突出部材１７ｂ及び突出部材２７ｂはそれぞれ付勢部材１７ａ及び加熱盤２０において付勢部材１７ａに相当する付勢部材（図示せず）の付勢力に逆らって、それぞれが保持部材１２、２２内部に向かって後退する。ここで、第２保持部材１７及び第２保持部材２７は、突出部材１７ｂと突出部材２７ｂとが、被加熱体Ｍと加熱部材１３との距離及び被加熱体Ｍと加熱部材２３との距離が等しくなるように後退するように構成されている。 When the heating panel 10 is further moved upward, as shown in FIG. 8A, the projecting member 17b and the projecting member 27b are respectively applied to the biasing member 17a and the biasing member (corresponding to the biasing member 17a in the heating panel 20). Against the urging force (not shown), each retracts toward the inside of the holding members 12,22. Here, as for the 2nd holding member 17 and the 2nd holding member 27, the protrusion member 17b and the protrusion member 27b are the distance of the to-be-heated body M and the heating member 13, and the distance of the to-be-heated body M and the heating member 23. It is configured to retreat to be equal.

更に加熱盤１０を上方に移動させ、図８（Ｂ）に示すように、加熱部材１３及び加熱部材２３を被加熱体Ｍに同時に接触させ、所定の加圧力を付加しながら加熱し、ヒートシールを行う。このとき、補助加熱部材１５及び補助加熱手段として作用する保持部材１２により加熱部材１３の接触部１３ｅ以外の領域が、加熱部材１３及び加熱部材２３より低い温度条件で加熱され、被加熱体Ｍの接触部と接触部以外の領域との間に過大な温度差が生じない。本実施形態では、被加熱体Ｍは保持部材１２及び補助加熱部材１５には接触していない。これにより、被加熱体Ｍは、加熱部材１３及び加熱部材２３のみで加圧されるため、他の領域に圧力が付加されることがなく、良好なヒートシールを行うことができる。 Further, the heating platen 10 is moved upward, and as shown in FIG. 8B, the heating member 13 and the heating member 23 are simultaneously brought into contact with the object to be heated M, heated while applying a predetermined pressure, and heat sealed. I do. At this time, the area other than the contact portion 13e of the heating member 13 is heated by the auxiliary heating member 15 and the holding member 12 acting as auxiliary heating means under a temperature condition lower than that of the heating member 13 and the heating member 23. An excessive temperature difference does not occur between the contact portion and the region other than the contact portion. In the present embodiment, the heated body M is not in contact with the holding member 12 and the auxiliary heating member 15. Thereby, since the to-be-heated body M is pressurized only with the heating member 13 and the heating member 23, pressure is not added to another area | region and it can perform favorable heat sealing.

被加熱体Ｍの加熱が終了すると、加熱盤１０を下方に移動させる。すると、図９（Ａ）に示すように、突出部材１７ｂ及び突出部材２７ｂはそれぞれ付勢部材１７ａ及び加熱盤２０において付勢部材１７ａに相当する付勢部材（図示せず）の付勢力によりそれぞれが保持部材１２、２２の外部に向かって突出し、被加熱体Ｍは加熱部材１３及び加熱部材２３から同時に離れる。 When the heating of the heated body M is completed, the heating panel 10 is moved downward. Then, as shown in FIG. 9A, the projecting member 17b and the projecting member 27b are respectively applied by the urging force of an urging member (not shown) corresponding to the urging member 17a in the urging member 17a and the heating panel 20, respectively. Protrudes toward the outside of the holding members 12, 22, and the heated body M is simultaneously separated from the heating member 13 and the heating member 23.

更に、加熱盤１０を下方に移動させると、図９（Ｂ）に示すように、被加熱体Ｍから突出部材２７ｂから離れる状態を経て、図７（Ａ）に示すような状態に戻る。そして、ヒートシールが行われた被加熱体Ｍを取り出す。上記工程を繰り返し、連続して被加熱体Ｍのヒートシールを行うことができる。 Further, when the heating panel 10 is moved downward, as shown in FIG. 9B, the state returns to the state as shown in FIG. And the to-be-heated body M in which heat sealing was performed is taken out. By repeating the above steps, the object to be heated M can be heat sealed continuously.

上述の加熱装置１を用いた加熱方法によれば、加熱部材１３は支持部材１４により保持部材１２から離間して支持されているので、加熱部材１３の熱が保持部材１２に直接伝達して散逸することを抑制することができる。これにより、加熱部材１３の温度を精度よく制御した状態で被加熱体Ｍの被加熱領域を加熱することができる。 According to the heating method using the heating device 1 described above, since the heating member 13 is supported by the support member 14 so as to be separated from the holding member 12, the heat of the heating member 13 is directly transmitted to the holding member 12 and dissipated. Can be suppressed. Thereby, the to-be-heated area | region of the to-be-heated body M can be heated in the state which controlled the temperature of the heating member 13 accurately.

補助加熱部材１５及び補助加熱手段として作用する保持部材１２により加熱部材１３の接触部１３ｅ以外の領域を、加熱部材１３より低温になるように制御して加熱することにより、被加熱体Ｍの接触部と接触部以外の領域との間に過大な温度差が生じることを防止することができる。これにより、被加熱体のしわ、そりなどの変形を防ぐことができる。また、補助加熱部材１５は加熱部材１３と離間するように設けられているとともに、補助加熱部材１５を用いない場合に比べて、加熱部材１３と周囲の部材との温度差を小さくすることができるので、加熱部材１３の熱が散逸することを抑制することができる。加熱部材１３と補助加熱部材１５及び保持部材１２とが独立して温度制御が可能に構成されているので、それぞれを所望の温度条件に設定して、良好な条件で被加熱体Ｍの加熱を行うことができる。 The area other than the contact portion 13e of the heating member 13 is controlled to be lower in temperature than the heating member 13 by the auxiliary heating member 15 and the holding member 12 acting as auxiliary heating means, thereby heating the object M to be heated. It is possible to prevent an excessive temperature difference from occurring between the portion and the region other than the contact portion. Thereby, deformations such as wrinkles and warpage of the heated body can be prevented. In addition, the auxiliary heating member 15 is provided so as to be separated from the heating member 13, and the temperature difference between the heating member 13 and the surrounding members can be reduced as compared with the case where the auxiliary heating member 15 is not used. Therefore, it can suppress that the heat of the heating member 13 dissipates. Since the heating member 13, the auxiliary heating member 15, and the holding member 12 are configured to be independently temperature-controllable, each is set to a desired temperature condition, and the object to be heated M is heated under good conditions. It can be carried out.

加熱部材１３は支持部材１４により保持部材１２に対する位置を調整可能に構成されているので、被加熱体Ｍとの位置関係を調整することができる。これにより、被加熱体Ｍの所望の被加熱領域を片当たりなどなく正確に加熱することができるので、良好な条件で被加熱体Ｍの加熱を行うことができる。 Since the heating member 13 is configured such that the position relative to the holding member 12 can be adjusted by the support member 14, the positional relationship with the heated object M can be adjusted. As a result, a desired heated region of the heated body M can be accurately heated without any contact, so that the heated body M can be heated under favorable conditions.

第２保持部材１７、２７により被加熱体Ｍをそれぞれ加熱部材１３、２３から離間して保持し、それぞれの加熱部材１３、２３に同時に接触させることができる。
これにより、被加熱体Ｍの被加熱領域を必要最小限の加熱により加圧しながら加熱することができるので、被加熱体Ｍへの熱影響を少なくすることができるとともに加熱条件を精度よく設定することができる。挟み込んで加熱するため、加熱部材１３、２３の熱を効率よく被加熱体Ｍに伝えることができる。また、被加熱体Ｍを加熱までの間に第２保持部材１７、２７により挟み込んで保持するため、被加熱体Ｍの位置ずれを防ぐことができる。特に、加熱で形状変化するシート状の部材、低剛性部材等を確実に固定して正確な位置で加熱することができ、好適である。 The heated object M can be held away from the heating members 13 and 23 by the second holding members 17 and 27 and can be brought into contact with the heating members 13 and 23 simultaneously.
As a result, the heated area of the heated body M can be heated while being pressed by the minimum necessary heating, so that the thermal influence on the heated body M can be reduced and the heating conditions are set accurately. be able to. Since it is sandwiched and heated, the heat of the heating members 13 and 23 can be efficiently transmitted to the heated object M. Moreover, since the to-be-heated body M is inserted | pinched and hold | maintained by the 2nd holding members 17 and 27 before a heating, the position shift of the to-be-heated body M can be prevented. In particular, a sheet-like member whose shape changes by heating, a low-rigidity member, or the like can be reliably fixed and heated at an accurate position, which is preferable.

加熱盤１０を、例えば熱硬化性樹脂の硬化処理などの用途において、被加熱体を載置して加熱する加熱盤として単独で使用することもできる。この場合には、被加熱体を加熱部材１３と離間して保持する必要がないため、第２保持部材１７を備えていない構成とすることができる。 The heating panel 10 can be used alone as a heating panel for placing and heating the object to be heated in applications such as a curing treatment of a thermosetting resin. In this case, since it is not necessary to hold the body to be heated apart from the heating member 13, the second holding member 17 can be omitted.

（変更例）
加熱部材１３、２３が被加熱体Ｍに接触して加熱可能であれば、被加熱体Ｍの形状等に合わせて、接触部１３ｅ、２３ｅ、保持部材１２、２２の表面１２ａ、２２ａ及び補助加熱部材１５、２５の表面１５ａ、２５ａの位置関係は任意に設定することができる。例えば、厚さ（高さ）が均一でなく、補助加熱部材１５、２５に対応する位置が厚く形成されている被加熱体Ｍを加熱する場合には、補助加熱部材１５、２５の表面１５ａ、２５ａを接触部１３ｅ、２３ｅより後退させることができる。また、被加熱体Ｍが低剛性部材の場合、加熱部材１３、２３のみで挟み込むと変形するおそれがあるので、接触部１３ｅ、２３ｅ、保持部材１２、２２表面１２ａ、２２ａ及び補助加熱部材１５、２５の表面１５ａ、２５ａを同一平面上となるように配置しても良い。 (Example of change)
If the heating members 13 and 23 are in contact with the heated body M and can be heated, the contact portions 13e and 23e, the surfaces 12a and 22a of the holding members 12 and 22 and the auxiliary heating are matched to the shape of the heated body M and the like. The positional relationship between the surfaces 15a and 25a of the members 15 and 25 can be arbitrarily set. For example, in the case of heating the object to be heated M in which the thickness (height) is not uniform and the positions corresponding to the auxiliary heating members 15 and 25 are formed thick, the surfaces 15a of the auxiliary heating members 15 and 25 are 25a can be retracted from the contact portions 13e and 23e. Further, when the object to be heated M is a low-rigidity member, there is a risk of deformation if it is sandwiched only by the heating members 13 and 23. Therefore, the contact portions 13e and 23e, the holding members 12 and 22, the surfaces 12a and 22a, and the auxiliary heating member 15, The 25 surfaces 15a and 25a may be arranged on the same plane.

加熱盤１０と加熱盤２０とで、保持部材１２、２２、加熱部材１３、２３及び補助加熱部材１５、２５の温度条件は、それぞれ独立に設定することができる。例えば、加熱盤２０の加熱部材２３の温度を加熱盤１０の加熱部材１３の温度よりも高く設定したりすることができる。 With the heating panel 10 and the heating panel 20, the temperature conditions of the holding members 12, 22, the heating members 13, 23 and the auxiliary heating members 15, 25 can be set independently. For example, the temperature of the heating member 23 of the heating panel 20 can be set higher than the temperature of the heating member 13 of the heating panel 10.

本実施形態では、被加熱体Ｍの位置決め部材として位置決めピン１８を用いたが、これに限定されるものではなく、例えば、枠状の部材で位置決めを行う構成を採用することができる。保持部材１２、加熱部材１３及び補助加熱部材１５を加熱する加熱手段としてヒータを用いたが、これに限定されるものではなく、例えば、熱媒配管等、公知の加熱手段を採用することができる。付勢部材１７ａとして、バネ等の弾性部材以外にも、電動アクチュエータ、流体を用いた圧力アクチュエータ等を採用することができる。補助加熱部材１５は、保持部材１２と一体的に形成することもできる。 In this embodiment, the positioning pin 18 is used as the positioning member of the heated body M, but the present invention is not limited to this, and for example, a configuration in which positioning is performed with a frame-shaped member can be employed. Although the heater is used as the heating means for heating the holding member 12, the heating member 13, and the auxiliary heating member 15, the present invention is not limited to this. For example, a known heating means such as a heat medium pipe can be adopted. . In addition to an elastic member such as a spring, an electric actuator, a pressure actuator using a fluid, or the like can be employed as the urging member 17a. The auxiliary heating member 15 can also be formed integrally with the holding member 12.

加熱部材１３が、複数に分割されて形成されている構成を採用することができる。図１０に示す例では、加熱部材１３は矩形状の各辺として４つに分割して配置されている。それぞれの加熱部材１３（１３Ａ−１３Ｄ）は、３つの支持部材１４により支持されており、それぞれの位置を調整可能に構成されている。これにより、加熱部材１３の被加熱体Ｍに対する平行度などの位置精度をより向上させることができる。また、ヒータ１３ｂ及び熱電対１３ｆをそれぞれ備えているので、温度条件を個別に設定することができる。 A configuration in which the heating member 13 is divided into a plurality of pieces can be employed. In the example shown in FIG. 10, the heating member 13 is divided into four parts as rectangular sides. Each heating member 13 (13A-13D) is supported by three support members 14, and each position can be adjusted. Thereby, positional accuracy, such as the parallelism with respect to the to-be-heated body M of the heating member 13, can be improved more. Moreover, since each of the heater 13b and the thermocouple 13f is provided, the temperature condition can be set individually.

加熱盤１０または加熱盤２０の少なくとも一方が、被加熱体Ｍへの加熱部材の片当たりを防ぐための調芯手段を備える構成を採用することができる。図１１に示すように、加熱盤１０において、補助加熱部材１５の下方に形成された空間に、調芯手段である球座５０が配置されている。球座５０は、台座１１上に設置されたベース５１の先端に設けられており、加熱部材１３の支持部材１４は球座５０下方に設けられた取付具５２を介して球座５０に接続されている。これにより、加熱盤２０の加熱部材２３との平行度が良好でなく片当たりが生じる状態でも、球座５０により加熱部材１３の向きが加熱部材２３に沿って変わるので、被加熱体Ｍへの加熱部材の片当たりを防ぐことができる。 (Other embodiments)
It is possible to employ a configuration in which at least one of the heating panel 10 or the heating panel 20 includes an alignment means for preventing the heating member from contacting the heated body M with one piece. As shown in FIG. 11, in the heating panel 10, a ball seat 50 as an alignment means is disposed in a space formed below the auxiliary heating member 15. The ball seat 50 is provided at the tip of a base 51 installed on the pedestal 11, and the support member 14 of the heating member 13 is connected to the ball seat 50 via a fixture 52 provided below the ball seat 50. ing. As a result, even when the parallelism of the heating panel 20 with the heating member 23 is not good and a single contact occurs, the orientation of the heating member 13 is changed along the heating member 23 by the ball seat 50, so The contact of the heating member can be prevented.

例えば、被加熱体Ｍが複数のシート状部材からなり、シート状部材を積層して圧着させる場合等には、下層のシート状部材を加熱盤１０に対して位置決めしても、上層のシート状部材が位置決めされておらず、加熱する前に位置ずれを生じるおそれがある。このような場合、図１２に示すように、加熱盤２０が、上層のシート状部材の移動を拘束する拘束手段である拘束部材を備えた構成を採用することができる。図１２に示すように、拘束部材６０は、被加熱体Ｍを押圧する押えパット６１と、コイルばね６２と、ガイドピン６３を備えている。コイルばね６２は、断熱部材２６と押えパット６１との間に配置され、押えパット６１を外方に付勢する。ガイドピン６３は、押えパット６１の裏面から押えパット６１を支持し、押えパット６１の位置決めを行う。押えパット６１の表面６１ａは加熱部材２３の接触部２３ｅよりも外方に位置している。ガイドピン６３の先端と押えパット６１との間には隙間が設けられている。加熱盤１０が上昇すると、被加熱体Ｍは、まず第２保持部材１７、２７に挟み込まれ、続いて押えパット６１に接触する。更に加熱盤１０が上昇すると、被加熱体Ｍから押えパット６１に力が負荷され、押えパット６１が変位するとともに、コイルばね６２の反力により押えパット６１は被加熱体Ｍを押圧する。そして、上層のシート状部材が押圧されて位置ずれが生じない状態で、加熱部材１３、２３が被加熱体Ｍに接触し加熱する。以上のように、拘束部材６０を備えた構成によれば、例えばシート状部材を積層した被加熱体など、位置ずれを起こしやすい被加熱体を押圧することにより拘束することができるので、被加熱体の位置ずれがない状態で加熱することができる。また、被加熱体Ｍとの接触面積が広いため被加熱体Ｍを保持するために必要な挟持力を分散することができる。これにより、被加熱体Ｍを保持するために被加熱体Ｍに加わる単位面積当たり挟持力が小さくなるため、保持によって被加熱体Ｍが破れたりつぶれたりすることを防ぐことができる。なお、本実施形態では、拘束部材６０は補助加熱部材として作動しない。 For example, when the heated body M is composed of a plurality of sheet-like members and the sheet-like members are laminated and pressure-bonded or the like, even if the lower-layer sheet-like member is positioned with respect to the heating panel 10, the upper-layer sheet-like member The member is not positioned, and there is a risk of misalignment before heating. In such a case, as shown in FIG. 12, the heating board 20 can employ a configuration including a restraining member that is restraining means for restraining the movement of the upper sheet-like member. As shown in FIG. 12, the restraining member 60 includes a presser pad 61 that presses the heated object M, a coil spring 62, and a guide pin 63. The coil spring 62 is disposed between the heat insulating member 26 and the presser pad 61 and urges the presser pad 61 outward. The guide pin 63 supports the presser pad 61 from the back surface of the presser pad 61 and positions the presser pad 61. The surface 61 a of the presser pad 61 is located outward from the contact portion 23 e of the heating member 23. A gap is provided between the tip of the guide pin 63 and the presser pad 61. When the heating panel 10 is raised, the heated body M is first sandwiched between the second holding members 17 and 27 and then comes into contact with the presser pad 61. When the heating panel 10 is further raised, a force is applied from the heated body M to the presser pad 61, the presser pad 61 is displaced, and the presser pad 61 presses the heated body M by the reaction force of the coil spring 62. And the heating members 13 and 23 contact the to-be-heated body M and heat in the state by which the upper sheet-like member is pressed and a position shift does not arise. As described above, according to the configuration including the restraining member 60, it can be restrained by pressing a heated body that is likely to be displaced, such as a heated body in which sheet-like members are stacked. Heating can be performed without any body displacement. Moreover, since the contact area with the to-be-heated body M is wide, the clamping force required in order to hold | maintain the to-be-heated body M can be disperse | distributed. Thereby, since the clamping force per unit area applied to the heated body M to hold the heated body M becomes small, the heated body M can be prevented from being torn or crushed by holding. In the present embodiment, the restraining member 60 does not operate as an auxiliary heating member.
