Abstract
Description
本発明は、樹脂から形成された樹脂部材を補修する補修方法に関する。 The present invention relates to a repair method for repairing a resin member formed from a resin.
従来、樹脂パネル等の樹脂部材が破損した場合に、その破損した箇所（被補修部）を補修する方法としては、はんだごて等によって被補修部周辺の樹脂を溶かして融着させる方法や、ニクロム線等の線状発熱体を発熱させて埋め込む方法が用いられてきた。しかし、これらの方法は、１回１回の修理対象が点又は線に限定され、面積を持った範囲を修理するには非効率なものであった。 Conventionally, when a resin member such as a resin panel is damaged, as a method of repairing the damaged portion (repaired portion), a method of melting and fusing the resin around the repaired portion with a soldering iron, A method of embedding a linear heating element such as a nichrome wire by generating heat has been used. However, these methods are inefficient for repairing a range having an area because a repair object is limited to a point or a line at a time.
そこで、特許文献１には、面積を有する形状のニクロム線等の接続部材を発熱させずに当接し、その後に通電して発熱させることで被補修部を溶融し、その内部に接続部材を埋設することで、２つの部分を接続する補修方法が開示されている。しかし、接続部材が通電に好適な線状である必要があり、また発熱分布が一様であることから複雑な構造の被補修部を補修ことはできない。また、通電のためには被補修部以外の箇所にもニクロム線等を配することとなり、補修後にこれらの除去が必要となる。 Therefore, in Patent Document 1, a connecting member such as a nichrome wire having an area is brought into contact without generating heat, and then the portion to be repaired is melted by energizing and generating heat, and the connecting member is embedded therein Thus, a repair method for connecting the two parts is disclosed. However, it is necessary that the connecting member has a linear shape suitable for energization, and since the heat generation distribution is uniform, the repaired portion having a complicated structure cannot be repaired. Further, for energization, nichrome wires or the like are also arranged in places other than the repaired part, and these need to be removed after repair.
本発明は、任意の形状の被補修部を簡便に補修することができる補修方法を提案することを課題とする。 This invention makes it a subject to propose the repair method which can repair the repaired part of arbitrary shapes simply.
本発明の補修方法は、

前記樹脂部材の被補修部に被誘電加熱性の接続部材を当接する工程と、
該接続部材の少なくとも一部を誘導加熱して前記被補修部内に埋設する工程とを含むことを特徴とする。
The repair method of the present invention is:
A repair method for repairing a resin member formed from resin,
A step of contacting a dielectric heating property connecting member to the repaired portion of the resin member;
And a step of inductively heating at least a part of the connecting member and embedding it in the repaired portion.
誘導加熱により接続部材を加熱することで、これに当接する樹脂部材の被補修部が溶融し、その内部に接続部材が埋設される。誘導加熱を利用することで接続部材を加熱し、樹脂部材を溶融させて補修することができる。また、誘導加熱に用いるコイルを配する時間によって接続部材の発熱量を調整でき、樹脂部材の要補修度に合わせた補修が可能となる。
ここで、「被誘電加熱性」とは、強電流のコイルを近づけることによって内部に電流が流れて発熱する性質を言う。被誘電加熱性の物質は、帯磁性を有し高抵抗の導電性を有するものが多い。高い被誘電加熱性を持つ物質として、鉄が広く知られている。
By heating the connecting member by induction heating, the repaired portion of the resin member that comes into contact therewith is melted, and the connecting member is embedded therein. By using induction heating, the connecting member can be heated and the resin member can be melted and repaired. In addition, the amount of heat generated by the connecting member can be adjusted according to the time for arranging the coil used for induction heating, and repairing according to the degree of repair required of the resin member becomes possible.
Here, “dielectric heating property” refers to the property of generating heat when a current flows inside by bringing a coil with a high current close thereto. Many dielectric heating materials have magnetic properties and high resistance conductivity. Iron is widely known as a material having a high dielectric heating property.

接続部材は、被補修部と同等の面積を必要とする。一方、溶融した樹脂部材に入り込んで埋設されるためには、細線状であることが好ましい。網目形状は、両方の要求を充足する。 The connecting member requires an area equivalent to the repaired part. On the other hand, in order to enter and embed the molten resin member, it is preferably a fine wire. The mesh shape satisfies both requirements.

By having the width, the connection member is embedded in both the repaired portion and the repair member. The strength of the repaired part after repair will be high.
本発明の補修方法は、

The width is smaller than the sum of the thickness of the repaired portion and the thickness of the repair member, and larger than one half of the sum of the thickness of the repaired portion and the thickness of the repair member.
接続部材は、被補修部と補修部材との双方の内部に深く埋設することが、補修後における被補修部のために好ましい。一方、被補修部又は補修部材を貫通して埋設されることは外観を乱してしまう。深く埋設されかつ貫通しない厚みを与える。 It is preferable for the repaired part after the repair that the connecting member is deeply embedded in both the repaired part and the repaired member. On the other hand, embedding through the repaired part or the repair member disturbs the appearance. Thickness that is deeply embedded and does not penetrate.

接続部材と支持部材とに挟まれる補修部材が接続部材のみに当接する被補修部より溶融が進むため、接続部材を補修部材側に埋設することができる。 Since the repair member sandwiched between the connection member and the support member is melted more than the repaired portion that contacts only the connection member, the connection member can be embedded on the repair member side.
本発明の補修方法は、
前記被補修部は開口を有し、
前記埋設する工程では、前記開口内に樹脂から形成された補助部材を配することを特徴とする。
The repair method of the present invention is:
The repaired part has an opening,
In the embedding step, an auxiliary member made of resin is disposed in the opening.
補助部材を開口内に配して被補修部内に接続部材を埋設することで、開口を有する被補修部を補修することができる。 By arranging the auxiliary member in the opening and burying the connecting member in the repaired portion, the repaired portion having the opening can be repaired.
本発明の補修方法によれば、誘導加熱を利用することにより任意の形状の接続部材を任意の熱分布で加熱して任意の形状の被補修部を補修することができる。 According to the repairing method of the present invention, it is possible to repair a repaired portion having an arbitrary shape by heating a connecting member having an arbitrary shape with an arbitrary heat distribution by using induction heating.
図１に、補修方法により補修される樹脂パネル２、樹脂パネル２の被補修部２ａを補強するための接続部材１、被補修部２ａを補修するための補修部材３、補修部材３を支持する支持部材４、及び接続部材１を誘導加熱するためのコイル（導線）５の配置を示す。なお、図１（Ａ）及び（Ｂ）は、それぞれ、樹脂パネル２等の断面図及び平面図である。 FIG. 1 supports a resin panel 2 to be repaired by a repair method, a connection member 1 for reinforcing a repaired portion 2a of the resin panel 2, a repair member 3 for repairing the repaired portion 2a, and a repair member 3. The arrangement of the support member 4 and the coil (conductive wire) 5 for induction heating the connection member 1 is shown. 1A and 1B are a cross-sectional view and a plan view of the resin panel 2 and the like, respectively.
樹脂パネル２は、一例として、自動車のボディ等の平板状のパネルを想定する。パネルの厚みは２ｍｍ〜４ｍｍのものが多いが、本実施例では３ｍｍとする。樹脂パネル２を形成する樹脂は、熱により溶融し、冷却して硬化するものであり、例えばポリエチレン等のポリオレフィン系樹脂、ポリ塩化ビニル等のビニル系樹脂、ポリメタクリル酸メチル等のアクリル樹脂、ＡＢＳ樹脂等の熱可塑性樹脂を選択することができる。 As an example, the resin panel 2 is assumed to be a flat panel such as an automobile body. The thickness of the panel is often 2 mm to 4 mm, but is 3 mm in this embodiment. The resin forming the resin panel 2 is melted by heat and cured by cooling. For example, a polyolefin resin such as polyethylene, a vinyl resin such as polyvinyl chloride, an acrylic resin such as polymethyl methacrylate, ABS, and the like. A thermoplastic resin such as a resin can be selected.
図１（Ｂ）より明らかなように、樹脂パネル２の中央が破損し、筋状のスリットが形成されている。このスリット及びその周囲を被補修部２ａとし、これを補修方法により接続部材１等を用いて補修する。 As is clear from FIG. 1B, the center of the resin panel 2 is broken, and a streak-like slit is formed. The slit and its periphery are used as a repaired portion 2a, and this is repaired by using the connecting member 1 or the like by a repair method.
接続部材１は、一例として網状に形成された部材を使用する。後述するように樹脂パネル２内に埋設することで、被補修部２ａを含む樹脂パネル２を２次元面内で補強することができる。なお、必ずしも網状の形状に限らず、被補修部２ａの表面に平行な互いに交差する２方向にそれぞれ延びる形状、すなわち２次元面内に広がる形状であれば、被補修部２ａの形状等に応じて任意の形状を採用することができる。 As the connection member 1, a member formed in a net shape is used as an example. By embedding in the resin panel 2 as described later, the resin panel 2 including the repaired portion 2a can be reinforced in a two-dimensional plane. Note that the shape is not necessarily limited to the net shape, and the shape extends in two directions intersecting each other parallel to the surface of the repaired portion 2a, that is, the shape spreads in a two-dimensional plane, depending on the shape of the repaired portion 2a, etc. Any shape can be adopted.
なお、接続部材１は、網状の部材をプレス加工するなどにより、例えば側面視で波型に変形することで、その厚み方向に構造を持たせてもよい。被補修部２ａが厚い場合に、特に補修部材３を用いて被補修部２ａを補修する場合に、被補修部２ａ（補修部材３を含む）の厚みに対して好適な厚み、すなわち被補修部２ａ（補修部材３を含む）の厚みより小さく、望ましくは０．５〜０．８倍程度に加工された接続部材１を用いることで、十分な強度をもって被補修部２ａを補修することが可能となる。本実施例では、接続部材１の厚みは４ｍｍとする。補修部材３の厚みは３ｍｍとする。被補修部２ａ（補修部材３を含む）の厚みが６ｍｍであり、接続部材１の厚みはその０．６７倍である。 The connecting member 1 may have a structure in the thickness direction by, for example, deforming it into a corrugated shape in a side view by pressing a net-like member. When the repaired portion 2a is thick, particularly when the repaired portion 2a is repaired using the repair member 3, a thickness suitable for the thickness of the repaired portion 2a (including the repair member 3), that is, the repaired portion It is possible to repair the repaired portion 2a with sufficient strength by using the connecting member 1 which is smaller than the thickness of 2a (including the repair member 3), and preferably processed to about 0.5 to 0.8 times. It becomes. In this embodiment, the thickness of the connecting member 1 is 4 mm. The thickness of the repair member 3 is 3 mm. The thickness of the repaired portion 2a (including the repair member 3) is 6 mm, and the thickness of the connection member 1 is 0.67 times that.
また、接続部材１は、被誘電加熱性の金属から構成されるものとする。これにより、後述するようにコイル（導線）５を励磁（交流電流を供給）して振動磁場を接続部材１に印加することで、接続部材１が自己発熱する、すなわち誘導加熱される。 Moreover, the connection member 1 shall be comprised from the metal of a dielectric heating property. As a result, the connection member 1 self-heats, that is, is induction-heated by exciting the coil (conductive wire) 5 (supplying an alternating current) and applying an oscillating magnetic field to the connection member 1 as described later.
補修部材３は、樹脂、望ましくは樹脂パネル２を構成する樹脂と同種の樹脂、或いはこれとほぼ等しい融点等の属性を有する樹脂から構成されたパネル状の部材である。補修対象の樹脂パネル２（被補修部２ａ）が薄い場合等に補修部材３を用いて補修することで、その厚みを調整して被補修部２ａを補強することができる。なお、被補修部２ａが十分な厚みを有する場合などには、補修部材３を用いて補修する必要はない。 The repair member 3 is a panel-like member made of resin, desirably the same type of resin as that constituting the resin panel 2, or a resin having an attribute such as a melting point substantially equal to this. When the resin panel 2 (repaired portion 2a) to be repaired is thin, etc., the repaired portion 2a can be reinforced by adjusting the thickness by repairing with the repair member 3. In addition, when the to-be-repaired part 2a has sufficient thickness etc., it is not necessary to repair using the repair member 3. FIG.
樹脂パネル２（被補修部２ａ）の厚みは３ｍｍ、補修部材３の厚みは３ｍｍ、接続部材１の厚みは４ｍｍであり、接続部材１の厚みは被補修部２ａの厚みと補修部材３の厚みとの和より小さく、被補修部２ａの厚みと補修部材３の厚みとの和の２分の１よりも大きい。 The thickness of the resin panel 2 (repaired part 2a) is 3 mm, the thickness of the repairing member 3 is 3 mm, the thickness of the connecting member 1 is 4 mm, and the thickness of the connecting member 1 is the thickness of the repaired part 2a and the thickness of the repairing member 3 And larger than one half of the sum of the thickness of the repaired portion 2a and the thickness of the repair member 3.
支持部材４は、樹脂パネル２（被補修部２ａ）の裏面側に配され、補修部材３（補修部材３を用いない場合は接続部材１）をその裏面にて支持する。被補修部２ａの裏面と補修部材３の表面との間に接続部材１が配される。支持部材４は、ここでは木等の非被誘電加熱性の部材から構成されるものとする。 The support member 4 is disposed on the back surface side of the resin panel 2 (repaired portion 2a), and supports the repair member 3 (the connection member 1 when the repair member 3 is not used) on the back surface thereof. The connecting member 1 is disposed between the back surface of the repaired portion 2a and the surface of the repair member 3. Here, the support member 4 is assumed to be composed of a non-dielectrically heatable member such as wood.
コイル（導線）５は、被誘電加熱性の部材を誘導加熱するための振動磁場の発生源であり、これを励磁（交流電流を供給）することでその下方にむけて振動磁場を誘起する。それにより、コイル５の下方に位置する被誘電加熱性の部材、すなわち接続部材１に振動磁場が印加され、接続部材１が自己発熱する。 The coil (conductive wire) 5 is a generation source of an oscillating magnetic field for inductively heating a dielectric heating member. By exciting this (supplying an alternating current), the oscillating magnetic field is induced downward. As a result, an oscillating magnetic field is applied to the dielectrically heatable member located below the coil 5, that is, the connecting member 1, and the connecting member 1 generates heat.
樹脂パネル２（被補修部２ａ）を補修する手順を説明する。 A procedure for repairing the resin panel 2 (repaired portion 2a) will be described.
図２（Ａ）に示すように、被補修部２ａの裏面側に支持部材４を配し、支持部材４上に補修部材３を支持し、補修部材３上に接続部材１を配置する。接続部材１の上方から被補修部２ａの裏面を接続部材１に当接し、被補修部２ａを下方（図中、黒塗り矢印の方向）に押圧する。この状態において、コイル５を励磁しつつ被補修部２ａ上をまんべんなく移動する。これにより、被補修部２ａの下方に位置する接続部材１が一様に誘導加熱され、接続部材１に当接する被補修部２ａ（の裏面）及び補修部材３（の表面）が溶融し、それらが接続部材１を内在して一体化する。 As shown in FIG. 2A, the support member 4 is disposed on the back side of the repaired portion 2 a, the repair member 3 is supported on the support member 4, and the connection member 1 is disposed on the repair member 3. The back surface of the repaired portion 2a is brought into contact with the connecting member 1 from above the connecting member 1, and the repaired portion 2a is pressed downward (in the direction of the black arrow in the figure). In this state, the coil 5 moves evenly over the repaired portion 2a while exciting the coil 5. Thereby, the connection member 1 located below the repaired portion 2a is uniformly induction-heated, and the repaired portion 2a (the back surface) and the repair member 3 (the front surface) that contact the connection member 1 are melted. Is integral with the connecting member 1.
次に、コイル５の励磁を停止して冷却する。図２（Ｂ）に示すように、被補修部２ａのスリット状の破損部が閉じ、接続部材１が被補修部２ａ及びこれと一体化した補修部材３内に埋設される。このとき、接続部材１は側面視波型に加工されて厚み方向に構造を有するため、接続部材１を、その上側及び下側それぞれ約半分を被補修部２ａ及び補修部材３内に埋設して、被補修部２ａと補修部材３との間に内在することで、十分な強度をもって被補修部２ａが補修される。 Next, excitation of the coil 5 is stopped and cooling is performed. As shown in FIG. 2B, the slit-like damaged portion of the repaired portion 2a is closed, and the connecting member 1 is embedded in the repaired portion 2a and the repair member 3 integrated therewith. At this time, since the connection member 1 is processed into a side-view wave shape and has a structure in the thickness direction, about half of the upper and lower sides of the connection member 1 are embedded in the repaired portion 2a and the repair member 3, respectively. The repaired portion 2a is repaired with sufficient strength by being present between the repaired portion 2a and the repair member 3.
最後に、被補修部２ａの表面を研磨して平らに加工し、塗料を塗布することで補修が完了する。 Finally, the surface of the repaired portion 2a is polished and processed to be flat, and the coating is applied to complete the repair.
以上詳細に説明したように、本実施例の補修方法によると、樹脂から形成された樹脂パネル２の被補修部２ａに被誘電加熱性の接続部材１を当接し、その少なくとも一部を誘導加熱して被補修部２ａ内に埋設することで被補修部２ａが補修される。誘導加熱により接続部材１を加熱することで、これに当接する被補修部２ａ及び補修部材３が溶融し、その内部に接続部材１が埋設される。 As described above in detail, according to the repairing method of the present embodiment, the dielectrically heatable connecting member 1 is brought into contact with the repaired portion 2a of the resin panel 2 formed of resin, and at least a part thereof is induction-heated. Then, the portion to be repaired 2a is repaired by being embedded in the portion to be repaired 2a. By heating the connecting member 1 by induction heating, the repaired portion 2a and the repair member 3 that are in contact with the connecting member 1 are melted, and the connecting member 1 is embedded therein.
また、誘導加熱を利用することで間接的に接続部材１を加熱することができるため、接続部材１を任意の形状に加工し、任意の分布で加熱して任意の形状の被補修部２ａを補修することが可能となる。例えば本実施例で使用した網状の接続部材１に電流を流して通電加熱するには、接続部材１の形状が複雑なため一様に加熱するのは困難である。 In addition, since the connection member 1 can be indirectly heated by using induction heating, the connection member 1 is processed into an arbitrary shape, heated in an arbitrary distribution, and the repaired portion 2a having an arbitrary shape is formed. It can be repaired. For example, in order to apply current to the mesh-like connection member 1 used in this embodiment and to heat it by energization, it is difficult to uniformly heat the connection member 1 because the shape of the connection member 1 is complicated.
なお、接続部材１をコイル５を用いて誘導加熱する際に、適宜、コイル５の励磁電流の量、接続部材１との距離及び角度、励磁時間等を調整することで、適当な分布で接続部材１を加熱することもできる。 In addition, when the connection member 1 is induction-heated using the coil 5, the connection is made with an appropriate distribution by appropriately adjusting the amount of excitation current of the coil 5, the distance and angle with the connection member 1, the excitation time, and the like. The member 1 can also be heated.
また、本実施例では、接続部材１を一様に誘導加熱することとしたが、励磁されたコイル５を例えば被補修部２ａ内のスリット（損傷部）に集中してその上方を移動することで、スリットの直下に位置する接続部材１の一部のみを誘導加熱することとしてもよい。コイル５から誘起される磁場は一定の指向性を有するため、任意の分布でもって接続部材を誘導加熱することができる。それにより、補修を要する部分のみに接続部材１を埋設することができる。 In the present embodiment, the connection member 1 is uniformly induction-heated. However, the excited coil 5 is concentrated on, for example, a slit (damaged portion) in the repaired portion 2a and moved above it. Thus, only a part of the connection member 1 located immediately below the slit may be induction-heated. Since the magnetic field induced from the coil 5 has a certain directivity, the connection member can be induction-heated with an arbitrary distribution. Thereby, the connection member 1 can be embedded only in the part which needs repair.
また、本実施例では、支持部材４を非被誘電加熱性の部材から構成するものとしたが、被誘電加熱性の部材より構成することとしてもよい。補修部材３を被誘電加熱性の支持部材４を用いて支持して接続部材１を介して被補修部２ａの裏面に当接する。この状態において、コイル５を励磁して接続部材１を誘導加熱することで、同時に支持部材４も誘導加熱される。それにより、接続部材１と支持部材４とに挟まれる補修部材３が接続部材１のみに当接する被補修部２ａより溶融が進むため、接続部材１を補修部材３側に埋設することができる。支持部材４の導電率を適宜選択することで、接続部材１の補修部材３側への埋設量を調整することもできる。 In this embodiment, the support member 4 is made of a non-dielectric heating member, but may be made of a dielectric heating member. The repair member 3 is supported by using a dielectric-heatable support member 4 and is brought into contact with the back surface of the repaired portion 2a through the connection member 1. In this state, the support member 4 is also induction heated at the same time by exciting the coil 5 and induction heating the connection member 1. Thereby, the melting of the repair member 3 sandwiched between the connection member 1 and the support member 4 proceeds from the repaired portion 2a that contacts only the connection member 1, so that the connection member 1 can be embedded on the repair member 3 side. By appropriately selecting the conductivity of the support member 4, the burying amount of the connection member 1 on the repair member 3 side can be adjusted.
図３（Ａ）に示すように、樹脂パネル２の中央が破損して大きな開口が形成されている。また、開口の周囲は樹脂パネル２の裏側に向かって屈曲している。この開口内側及びその周囲を被補修部２ａとし、これを補修方法により接続部材１、補助部材６等を用いて補修する。なお、本実施例は、補助部材６を用いること、これに関連することを除いて先述の実施例１と同様であるため、相違のみに集中して説明することとする。 As shown in FIG. 3A, the center of the resin panel 2 is broken to form a large opening. Further, the periphery of the opening is bent toward the back side of the resin panel 2. The inside of the opening and the periphery thereof are used as a repaired portion 2a, and this is repaired using the connecting member 1, the auxiliary member 6 and the like by a repairing method. Note that this embodiment is the same as the first embodiment described above except that the auxiliary member 6 is used and related to this, so that only the differences will be described.
樹脂パネル２（被補修部２ａ）を補修する手順を説明する。 A procedure for repairing the resin panel 2 (repaired portion 2a) will be described.
図３（Ａ）に示すように、被補修部２ａの裏面側に支持部材４を配し、支持部材４上に補修部材３を支持し、補修部材３上に接続部材１を配置する。接続部材１の上方から被補修部２ａ（開口の周囲）の裏面を接続部材１に当接し、被補修部２ａを下方（図中、黒塗り矢印の方向）に押圧する。この状態において、コイル５を励磁しつつ被補修部２ａの開口の周囲の上を移動する。これにより、開口の周囲の下方に位置する接続部材１が誘導加熱され、接続部材１に当接する被補修部２ａ（開口の周囲）が変形して平坦になり、補修部材３とともに溶融して、図３（Ｂ）に示すようにそれらが接続部材１を内在して一体化する。ただし、接続部材１は被補修部２ａの開口内に一部を突出する。 As shown in FIG. 3A, the support member 4 is disposed on the back side of the repaired portion 2 a, the repair member 3 is supported on the support member 4, and the connection member 1 is disposed on the repair member 3. The back surface of the repaired portion 2a (around the opening) is brought into contact with the connecting member 1 from above the connection member 1, and the repaired portion 2a is pressed downward (in the direction of the black arrow in the figure). In this state, the coil 5 moves around the opening of the repaired portion 2a while exciting the coil 5. As a result, the connection member 1 located below the periphery of the opening is induction-heated, the repaired portion 2a (around the opening) that contacts the connection member 1 is deformed and flattened, and melted together with the repair member 3, As shown in FIG. 3 (B), they inherently integrate the connecting member 1. However, the connection member 1 partially projects into the opening of the repaired portion 2a.
次に、図４（Ａ）に示すように、被補修部２ａの開口内に樹脂から形成された補助部材６を配する。補助部材６は、補修部材３と同様に、樹脂、望ましくは樹脂パネル２を構成する樹脂と同種の樹脂、或いはこれとほぼ等しい融点等の属性を有する樹脂から構成されたパネル状の部材であり、被補修部２ａの開口内に配することができるよう、その形状に合わせて切断されている。接続部材１の上方から補助部材６の裏面を接続部材１に当接し、補助部材６を下方（図中、黒塗り矢印の方向）に押圧する。この状態において、コイル５を励磁しつつ補助部材６上を移動する。これにより、補助部材６の下方に位置する接続部材１が誘導加熱され、接続部材１に当接する補助部材６、被補修部２ａ、及び補修部材３が溶融し、図４（Ｂ）に示すようにそれらが接続部材１を内在して一体化する。 Next, as shown in FIG. 4A, the auxiliary member 6 made of resin is disposed in the opening of the repaired portion 2a. The auxiliary member 6 is a panel-like member made of resin, desirably the same type of resin as that constituting the resin panel 2, or a resin having an attribute such as a melting point substantially equal to the resin, like the repair member 3. It is cut according to its shape so that it can be placed in the opening of the repaired part 2a. The back surface of the auxiliary member 6 is brought into contact with the connecting member 1 from above the connecting member 1, and the auxiliary member 6 is pressed downward (in the direction of the black arrow in the figure). In this state, the auxiliary member 6 is moved while exciting the coil 5. As a result, the connecting member 1 located below the auxiliary member 6 is induction-heated, and the auxiliary member 6, the repaired portion 2a, and the repair member 3 that are in contact with the connecting member 1 are melted, as shown in FIG. They are integral with the connecting member 1.
次に、コイル５の励磁を停止して冷却する。図４（Ｂ）に示すように、被補修部２ａの開口が閉じ、接続部材１が被補修部２ａ並びにこれと一体化した補助部材６及び補修部材３内に埋設される。このとき、接続部材１は側面視波型に加工されて厚み方向に構造を有するため、接続部材１を、その上側及び下側それぞれ約半分を被補修部２ａ及び補助部材６並びに補修部材３内に埋設して、被補修部２ａと補助部材６と補修部材３との間に内在することで、十分な強度をもって被補修部２ａが補修される。 Next, excitation of the coil 5 is stopped and cooling is performed. As shown in FIG. 4B, the opening of the repaired portion 2a is closed, and the connecting member 1 is embedded in the repaired portion 2a and the auxiliary member 6 and the repair member 3 integrated therewith. At this time, since the connection member 1 is processed into a side-view wave shape and has a structure in the thickness direction, the connection member 1 has about half of the upper side and the lower side in the repaired portion 2a, the auxiliary member 6, and the repair member 3, respectively. The repaired portion 2a is repaired with sufficient strength by being embedded between the repaired portion 2a, the auxiliary member 6 and the repair member 3.
最後に、被補修部２ａの表面を研磨して平らに加工し、塗料を塗布することで補修が完了する。 Finally, the surface of the repaired portion 2a is polished and processed to be flat, and the coating is applied to complete the repair.
以上詳細に説明したように、本実施例の補修方法によると、樹脂から形成された樹脂パネル２の被補修部２ａ内に補助部材６を配し、それらに被誘電加熱性の接続部材１を当接し、その少なくとも一部を誘導加熱して被補修部２ａ内に埋設することで被補修部２ａが補修される。誘導加熱により接続部材１を加熱することで、これに当接する被補修部２ａ、補助部材６、及び補修部材３が溶融し、その内部に接続部材１が埋設される。誘導加熱を利用することで間接的に接続部材１を加熱することができるため、任意の形状の接続部材１を任意の分布で加熱して任意の形状の被補修部２ａを補修することが可能となる。また、補助部材６を開口内に配して被補修部２ａ内に接続部材１を埋設することで、開口を有する被補修部２ａを補修することができる。 As described above in detail, according to the repairing method of the present embodiment, the auxiliary member 6 is arranged in the repaired portion 2a of the resin panel 2 made of resin, and the dielectrically heatable connecting member 1 is provided to them. The part to be repaired 2a is repaired by abutting and induction-heating at least a part of the part to be embedded in the part 2a to be repaired. By heating the connecting member 1 by induction heating, the repaired portion 2a, the auxiliary member 6, and the repairing member 3 that are in contact with the connecting member 1 are melted, and the connecting member 1 is embedded therein. Since the connection member 1 can be indirectly heated by using induction heating, it is possible to repair the repaired portion 2a of any shape by heating the connection member 1 of any shape with any distribution. It becomes. Moreover, the repairing part 2a which has an opening can be repaired by arranging the auxiliary member 6 in the opening and embedding the connecting member 1 in the repaired part 2a.
本発明の補修方法は、任意の形状の被補修部を補修するのに好適である。多くの自動車修理業者等による利用が期待される。 The repair method of the present invention is suitable for repairing a repaired part having an arbitrary shape. Expected to be used by many auto repairers.
