Description
本発明は、樹脂溶融用レーザ光源と樹脂分解用レーザ光源を用いて接合部の樹脂材料を加熱することによって金属材料と樹脂材料を効率的に接合する方法に関する。 The present invention relates to a method for efficiently joining a metal material and a resin material by heating a resin material at a joint using a laser light source for resin melting and a laser light source for resin decomposition.
従来の金属材料と樹脂材料の接合に使用される方法としては、リベット締結や接着剤を用いる方法がある。リベット締結は、金属材料と樹脂材料を貫通するように、数ｍｍから数十ｍｍ程度の直径を有するリベットを打ち込んで固定する物理的な締結方法である。一方、接着は、金属材料と樹脂材料を接着剤によって物理的吸着力及び化学的吸着力により固定する方法である。 Conventional methods used for joining a metal material and a resin material include rivet fastening and a method using an adhesive. Rivet fastening is a physical fastening method in which a rivet having a diameter of several millimeters to several tens of millimeters is driven and fixed so as to penetrate a metal material and a resin material. On the other hand, the adhesion is a method of fixing a metal material and a resin material by an adhesive with a physical adsorption force and a chemical adsorption force.
また、レーザを用いた接合では、金属材料同士や樹脂材料同士を溶接及び溶着することで接合する方法が実用化されているが、金属材料と樹脂材料との接合は行われていない。ただ、近年、レーザ樹脂溶着では，レーザ光の波長に対して透明な材料と不透明な材料を重ね合わせて、レーザ光を透明な材料側から照射し、接合部のみを溶融させ接合する画期的な方法が実用化されている。この方法では、接合面積も広くとれ、さらに加熱時の樹脂の分解に基づくガスの発生を抑えることもできる（特許文献１〜３、非特許文献１参照）。 Moreover, in the joining using a laser, although the method of joining by welding and welding metal materials or resin materials is put into practical use, joining with a metal material and a resin material is not performed. However, in recent years, laser resin welding is an epoch-making process in which a transparent material and an opaque material are superimposed on the wavelength of the laser beam, and the laser beam is irradiated from the transparent material side to melt and bond only the joint. Have been put to practical use. In this method, a large bonding area can be obtained, and generation of gas based on decomposition of the resin during heating can be suppressed (see Patent Documents 1 to 3 and Non-Patent Document 1).
金属材料と樹脂材料を接合する要望は非常に強い。その理由としては、必要な部分のみ金属材料を使用し、残りを樹脂材料に置き換えることで、樹脂材料の重量やコストが金属材料に比べていずれも半分以下であることから、大幅な重量とコストの削減が期待でき、絶縁体の樹脂材料に優れた電気・熱特性に関する設計自由度の向上、あるいは、それらを組み合わせることで、新しい複合機能性材料の創出など様々なメリットが挙げられる。 The demand for joining metal materials and resin materials is very strong. The reason is that the metal material is used only for the necessary part and the rest is replaced with the resin material, so that the weight and cost of the resin material are less than half compared to the metal material. There are various merits such as the improvement of the design flexibility regarding the electrical and thermal characteristics superior to the insulating resin material, or the creation of a new composite functional material by combining them.
しかしながら、従来の金属材料と樹脂材料の接合方法であるリベット締結や接着剤を用いる方法では、適用分野が限定されるのが現状である。リベット締結では、締結部にある程度の大きさ・重量があるため、部品の大型化・重量化が避けられず、設計の自由度も低下するので、大型あるいは単純な商品あるいは部品に主に適用されている。一方、接着は、大型化・重量化することはないが、技術的な面で、接着剤が濡れ広がるために精密なピンポイントの接合が難しい点、平面より凸凹表面の方が接着強度は高くなるなど接着表面の制限、生産面では、硬化時間が長いため生産タクトの低下や接着剤の状態維持・管理が難しいなど課題が存在する。また、レーザを用いた接合では、樹脂同士の接合のように、レーザ波長に対して透明な樹脂材料と不透明な樹脂材料を使用しなければならず、材料選択に制限があることや、透明な樹脂材料の方からしかレーザ照射できないことによる生産技術面での課題も存在する。 However, the current field of application is limited in rivet fastening, which is a conventional method for joining a metal material and a resin material, or a method using an adhesive. In rivet fastening, the fastening part has a certain size and weight, so it is unavoidable to increase the size and weight of the part, and the degree of freedom in design is reduced, so it is mainly applied to large or simple products or parts. ing. On the other hand, bonding does not increase in size and weight, but on the technical side, it is difficult to bond pinpoints precisely because the adhesive spreads wet, and the uneven surface has higher adhesive strength than the flat surface. In terms of the limitation of the adhesive surface and production, there are problems such as a decrease in production tact and difficulty in maintaining and managing the adhesive state due to the long curing time. In addition, in joining using a laser, it is necessary to use a transparent resin material and an opaque resin material with respect to the laser wavelength, as in the case of joining between resins, and there are restrictions on material selection, There are also problems in production technology due to laser irradiation only from the resin material.
本発明者等は、かかる現状に鑑み、これらの課題を克服した金属樹脂接合方法として、レーザ光源を用いて金属材料と樹脂材料を合わせた状態で接合部の樹脂材料に特定の大きさの気泡を発生させる温度まで加熱することにより金属材料と樹脂材料を強固に接合する方法を既に提案した（特許文献４参照）。しかしながら、実際にレーザ光源によって樹脂材料を所望の位置で所望の状態に効率良く加熱することは、困難な場合があり、金属材料と樹脂材料の強固な接合のために好適かつ効率的なレーザ加熱方法が求められていた。
本発明は、かかる従来技術の現状に鑑み創案されたものであり、その目的は、レーザ光源を用いて接合部の樹脂材料に特定の大きさの気泡を発生させる温度まで加熱することにより金属材料と樹脂材料を接合する方法において、樹脂材料の加熱場所及び加熱温度の制御が極めて容易でかつ効率的なレーザ光源の使用方法を提供することにある。 The present invention was devised in view of the current state of the prior art, and its purpose is to use a laser light source to heat a metal material by heating to a temperature at which bubbles of a specific size are generated in the resin material of the joint. It is an object of the present invention to provide a method of using a laser light source that is extremely easy and efficient in controlling the heating location and heating temperature of the resin material.
本発明者等は、上記目的を達成するために鋭意検討した結果、樹脂材料を加熱するレーザ光源として、樹脂溶融用レーザ光源と樹脂分解用レーザ光源を併用し、樹脂溶融用レーザ光源の照射で樹脂を溶融させ、さらにその溶融した樹脂に樹脂分解用レーザ光源を照射して樹脂を分解することにより、樹脂材料の加熱場所及び加熱温度を好適に制御しながら効率的に樹脂をレーザ加熱できることを見出し、本発明の完成に至った。 As a result of intensive investigations to achieve the above object, the present inventors have used both a resin melting laser light source and a resin decomposition laser light source as a laser light source for heating a resin material. By melting the resin and irradiating the molten resin with a laser light source for resin decomposition to decompose the resin, the resin can be efficiently laser-heated while suitably controlling the heating location and heating temperature of the resin material. The headline, the present invention has been completed.
即ち、本発明は、レーザ光源を用いて金属材料と樹脂材料を合わせた状態で接合部の樹脂材料に気泡を発生させる温度まで加熱することにより金属材料と樹脂材料を接合する方法において、レーザ光源として、樹脂材料を溶融させる温度に加熱する樹脂溶融用レーザ光源と樹脂材料を分解させる温度に加熱する樹脂分解用レーザ光源を使用することを特徴とする金属樹脂接合方法である。 That is, the present invention relates to a method of joining a metal material and a resin material by heating to a temperature at which bubbles are generated in the resin material of the joint in a state where the metal material and the resin material are combined using a laser light source. As a metal resin bonding method, a resin melting laser light source that is heated to a temperature at which the resin material is melted and a laser light source for resin decomposition that is heated to a temperature at which the resin material is decomposed are used.
本発明の上記方法の好ましい態様では、樹脂溶融用レーザ光源の照射によって樹脂材料が溶融されている範囲に対して、樹脂分解用レーザ光源を照射して樹脂材料を分解するものであり、接合部の樹脂材料に発生される気泡の球相当直径が０．０１ｍｍ〜１ｍｍであり、樹脂材料が熱可塑性である。 In a preferred embodiment of the above method of the present invention, the resin material is decomposed by irradiating the resin light source for resin decomposition with respect to the range where the resin material is melted by irradiation of the resin light source for resin melting, The equivalent sphere diameter of bubbles generated in the resin material is 0.01 mm to 1 mm, and the resin material is thermoplastic.
また、本発明は、上記方法により金属材料と樹脂材料が接合された接合部を有することを特徴とする金属樹脂複合体である。 Moreover, this invention is a metal resin composite characterized by having the junction part by which the metal material and the resin material were joined by the said method.
本発明の方法は、接合部の樹脂材料に特定の大きさの気泡を発生させる温度まで加熱することにより金属材料と樹脂材料を接合する方法において、加熱源として樹脂溶融用レーザ光源と樹脂分解用レーザ光源を併用しているので、樹脂の加熱場所及び加熱温度の制御が極めて容易かつ効率的であり、結果として高い強度の金属樹脂接合部の均一な形成に大きく寄与することができる。 The method of the present invention is a method of joining a metal material and a resin material by heating to a temperature at which a bubble of a specific size is generated in the resin material of the joint portion. Since the laser light source is used in combination, the control of the resin heating location and the heating temperature is extremely easy and efficient, and as a result, it can greatly contribute to the uniform formation of a high strength metal resin joint.
以下に本発明を具体的に説明する。
本発明の方法で使用する金属材料としては、鉄、アルミニウム、チタン、銅等及びそれらの合金が挙げられるが、特に限定されない。本発明においては、接合部を高い温度まで急速加熱できる、炭素鋼、ステンレス鋼、チタン合金等からなる金属材料が特に好ましい。金属材料は、樹脂材料との接合力を高めるための表面処理を行ったものが好ましい。金属材料の厚さは特に限定されず、０．１ｍｍ以上、さらには１ｍｍ以上、さらには３ｍｍ以上の厚さの金属材料であっても構わない。

In the present invention, a metal material made of carbon steel, stainless steel, titanium alloy or the like that can rapidly heat the joint to a high temperature is particularly preferable. The metal material is preferably subjected to a surface treatment for increasing the bonding force with the resin material.

In particular, a resin material having a polar group or a group reactive with a metal at its main chain, side chain and / or terminal is preferable, such as polyamide resin (PA), polyester resin, polycarbonate (PC), carboxylic acid group or sulfonic acid metal. Styrenic resins and acrylic resins having a polar group such as a base or a group reactive with a metal at the side chain and / or terminal are preferred. In particular, a resin material made of an amorphous resin having a polar group or a group reactive with a metal at the main chain, side chain, and / or terminal is preferable. In addition, it is preferable that the resin material has oxygen in the constituent atoms because a chemical bond is easily formed with the oxide on the surface of the metal and high bonding strength can be obtained. In addition, you may use what added reinforcing fibers, coloring materials, a heat stabilizer, a light stabilizer, etc., such as glass fiber and a carbon fiber, as the resin material in this invention.
また、本発明の方法で使用する樹脂材料は、レーザ光源による加熱によって気泡を発生する樹脂材料であることが必要である。例えば、吸湿した樹脂材料中の水分が加熱されることによるガス発生や高温において樹脂材料が分解されることによるガス発生によって気泡を発生する樹脂材料が用いられる。樹脂材料の厚さは特に限定されず、５０μｍ以上、さらには０．１ｍｍ以上、さらには１ｍｍ以上、さらには３ｍｍ以上の厚さの樹脂材料であっても構わない。 In addition, the resin material used in the method of the present invention needs to be a resin material that generates bubbles by heating with a laser light source. For example, a resin material that generates bubbles due to gas generation due to heating of moisture in the hygroscopic resin material or gas generation due to decomposition of the resin material at a high temperature is used. The thickness of the resin material is not particularly limited, and may be a resin material having a thickness of 50 μm or more, further 0.1 mm or more, further 1 mm or more, and further 3 mm or more.
本発明の方法では、金属材料と樹脂材料を合わせた状態で接合部をレーザ光源で加熱することにより両材料を強固に接合することができる。接合部の加熱温度は、樹脂材料内部に微細な気泡を発生させる温度であることが必要であり、具体的には樹脂の軟化温度以上で金属の沸点未満であり、接合部において２００℃〜１５００℃であることが好ましい。また、加熱温度は、樹脂の気泡が接合部付近からの移動を伴うような高い温度にしないことが好ましい。樹脂中の気泡が移動すると、接合部における気泡発生に伴う圧力と熱による接合が期待できなくなるからである。なお、加熱により接合部の樹脂中に発生する気泡の球相当直径の上限は、接合強度や外観の点から５ｍｍ以下、好ましくは３ｍｍ以下、さら好ましくは１ｍｍ以下、特に好ましくは０．５ｍｍ以下である。下限は接合強度の点から０．０００１ｍｍ以上、好ましくは０．００１ｍｍ以上、さら好ましくは０．０１ｍｍ以上である。 In the method of the present invention, both materials can be firmly bonded by heating the bonding portion with a laser light source in a state where the metal material and the resin material are combined. The heating temperature of the bonding portion needs to be a temperature that generates fine bubbles inside the resin material, specifically, is higher than the softening temperature of the resin and lower than the boiling point of the metal, and 200 ° C. to 1500 ° C. at the bonding portion. It is preferable that it is ° C. The heating temperature is preferably not set to such a high temperature that the resin bubbles are accompanied by movement from the vicinity of the joint. This is because if the bubbles in the resin move, bonding due to pressure and heat associated with the generation of bubbles in the bonded portion cannot be expected. In addition, the upper limit of the sphere equivalent diameter of bubbles generated in the resin at the joint by heating is 5 mm or less, preferably 3 mm or less, more preferably 1 mm or less, and particularly preferably 0.5 mm or less from the viewpoint of bonding strength and appearance. is there. The lower limit is 0.0001 mm or more, preferably 0.001 mm or more, more preferably 0.01 mm or more from the viewpoint of bonding strength.
本発明の方法で使用するレーザ光源としては、例えば、ＹＡＧレーザ、ファイバーレーザ、半導体レーザ、炭酸ガスレーザ等を用いることができる。また、これらの加熱源の照射は、連続照射又はパルス照射のいずれでもよい。
なお、レ−ザ光源を使用する場合は、レーザのパワー、パワー密度、加工速度（移動速度）や焦点はずし距離等の照射条件は、目的に応じて適宜設定可能である。例えば、レーザのパワー密度は、１Ｗ／ｍｍ２〜１０ｋＷ／ｍｍ２が好ましい。また、金属材料と樹脂材料の接合面付近の樹脂材料のみに微細な気泡を発生させる条件を設定することが好ましい。具体的には、レーザのパワーを大きくすると接合部が高温になり、その後の冷却も遅くなり樹脂中に発生する気泡も大きくなり、一方、パワーを小さくすると樹脂中に気泡が発生しないか、気泡が極端に少なくなり、接合強度は小さくなる。接合強度は、適切なサイズの気泡を急速に発生させることにより、溶融した状態の樹脂を金属の表面に密着するようにすると、高くなる。また、レーザの焦点はずし距離を大きくすると、パワー密度が小さくなるため、それをカバーする大きなパワーのレーザを照射することができ、その結果広い条件範囲で良好な接合部が得られ、制御が容易である。また、レーザの移動速度を高くすると、好適な接合が得られるレーザパワーの範囲が広くなるので制御が容易になる。なお、レーザの照射の方向は、金属材料と樹脂材料を合わせた状態でいずれの材料側から行っても強固な接合部を形成することができる。
As a laser light source used in the method of the present invention, for example, a YAG laser, a fiber laser, a semiconductor laser, a carbon dioxide gas laser, or the like can be used. Further, the irradiation of these heating sources may be either continuous irradiation or pulse irradiation.
When a laser light source is used, irradiation conditions such as laser power, power density, processing speed (moving speed), and defocus distance can be set as appropriate according to the purpose. For example, the power density of the laser is preferably 1 W / mm 2 to 10 kW / mm 2 . Moreover, it is preferable to set conditions for generating fine bubbles only in the resin material in the vicinity of the joint surface between the metal material and the resin material. Specifically, when the power of the laser is increased, the joint becomes hot, and the subsequent cooling also slows down and bubbles generated in the resin also increase. On the other hand, if the power is decreased, bubbles are not generated in the resin, or bubbles are generated. Is extremely reduced, and the bonding strength is reduced. The bonding strength increases when the molten resin is brought into close contact with the metal surface by rapidly generating bubbles of appropriate size. In addition, if the laser defocusing distance is increased, the power density decreases, so that it is possible to irradiate a large power laser that covers it, and as a result, good joints can be obtained over a wide range of conditions, and control is easy. It is. In addition, when the moving speed of the laser is increased, the laser power range in which a suitable bonding can be obtained is widened, so that the control becomes easy. Note that a strong bonding portion can be formed by performing laser irradiation from any material side in a state where the metal material and the resin material are combined.
本発明の方法は、接合部を加熱するレーザ光源として、樹脂材料を溶融させる温度に加熱する樹脂溶融用レーザ光源と樹脂材料を分解させる温度に加熱する樹脂分解用レーザ光源を使用することを特徴とする。単一のレーザ光源で接合部の樹脂材料を加熱すると、パワー密度分布を均一に制御できない場合、レーザ照射中央部に過剰に大きな気泡が発生したり、蒸発領域が発生したりして、高い接合強度を得られないおそれがある。従って、本発明では、接合部の樹脂材料の加熱場所と加熱温度を自在に制御して均一な樹脂材料の気泡発生状態を作るために樹脂溶融用レーザ光源と樹脂分解用レーザ光源の少なくとも二つのレーザ光源を使用する。実際には、まず樹脂溶融用レーザ光源の照射によって接合部の樹脂材料の比較的広い範囲を予め溶融させておき、次にその溶融した樹脂材料の所望の比較的狭い場所に樹脂分解用レーザ光源を照射して樹脂材料を分解して適度な大きさの気泡を発生させるように使用する。これによって、所望の場所に高い接合強度を有する接合部を作り出すことができる。 The method of the present invention uses, as a laser light source for heating a joint, a resin melting laser light source for heating to a temperature for melting a resin material and a resin light source for resin decomposition for heating to a temperature for decomposing the resin material. And If the power density distribution cannot be controlled uniformly by heating the resin material at the joint with a single laser light source, an excessively large bubble is generated at the center of the laser irradiation or an evaporation region is generated, resulting in high bonding. There is a possibility that strength cannot be obtained. Therefore, in the present invention, in order to create a uniform bubble generation state of the resin material by freely controlling the heating location and heating temperature of the resin material at the joint, at least two of the resin melting laser light source and the resin decomposition laser light source are used. Use a laser light source. In practice, first, a relatively wide range of the resin material at the joint is melted beforehand by irradiation with a resin melting laser light source, and then the resin decomposition laser light source is placed in a desired relatively narrow area of the molten resin material. Is used so that the resin material is decomposed to generate bubbles of an appropriate size. This makes it possible to create a joint having high joint strength at a desired location.
樹脂溶融用レーザ光源は、上述の従来公知のいずれのレーザ光源も使用することができるが、比較的広い範囲で樹脂を溶融して液体状態にすることができる照射条件を適宜設定することが必要である。また、樹脂分解用レーザ光源は、上述の従来公知のいずれのレーザ光源も使用することができるが、樹脂溶融用レーザ光源の照射により溶融された樹脂を分解して接合強度に好適な大きさの気泡を発生することができる照射条件を適宜設定することが必要である。 As the resin melting laser light source, any of the above-mentioned conventionally known laser light sources can be used. However, it is necessary to appropriately set irradiation conditions that can melt the resin into a liquid state in a relatively wide range. It is. In addition, any of the above-described conventionally known laser light sources can be used as the resin light source for resin decomposition, but the resin melted by the irradiation of the laser light source for resin melting is decomposed to have a size suitable for bonding strength. It is necessary to appropriately set irradiation conditions that can generate bubbles.
本発明の方法では、金属材料と樹脂材料を合わせた状態で、金属材料と樹脂材料の接合部を加熱することによって、樹脂材料内部から熱分解されたガスが膨らみ、樹脂内部に微細な気泡を発生させる。原理は明確ではないが、この時サブミリサイズ領域で、気泡発生に伴う爆発的な圧力が接合部にかかり、接合部の金属材料及び樹脂材料の温度が高くなっていることと相まって、気泡周辺部の樹脂材料と金属材料が、アンカー効果などの物理的な接合力及び／又は金属の酸化物を通した化学的な接合力で金属と樹脂とが接合できる条件を満たし接合する。さらに、樹脂材料が冷え固まる際には、気泡の温度も減少するため、気泡内部の圧力が低下し、吸着力も発生する。これらの接合力が複合した形で強固な金属と樹脂との接合が可能になる。加熱源として複数のレーザ光を使用することで、局所的な急激な加熱と急激な冷却が可能になり、気泡発生に伴う圧力・吸着力を増加させることでき、金属材料と樹脂材料の接合を促進させることができる。本発明の方法によって金属材料と樹脂材料とが接合された複合体は、１ＭＰａ以上、さらには５ＭＰａ以上、さらには１０ＭＰａ以上の引張剪断強度を有する強固な接合部を有することができる。 In the method of the present invention, in a state where the metal material and the resin material are combined, by heating the joint portion between the metal material and the resin material, the pyrolyzed gas expands from the inside of the resin material, and fine bubbles are generated inside the resin. generate. The principle is not clear, but at this time, in the submillimeter size region, the explosive pressure accompanying the generation of bubbles is applied to the joint, and the temperature of the metal material and resin material of the joint is high, and the periphery of the bubble The resin material and the metal material satisfy the condition that the metal and the resin can be bonded by a physical bonding force such as an anchor effect and / or a chemical bonding force through the metal oxide. Further, when the resin material cools and hardens, the temperature of the bubbles also decreases, so that the pressure inside the bubbles is reduced and an adsorption force is also generated. A strong metal and resin can be bonded in a form in which these bonding forces are combined. By using multiple laser beams as a heating source, local rapid heating and rapid cooling are possible, pressure and adsorption force associated with bubble generation can be increased, and metal materials and resin materials can be joined. Can be promoted. The composite in which the metal material and the resin material are joined by the method of the present invention can have a strong joint having a tensile shear strength of 1 MPa or more, further 5 MPa or more, and further 10 MPa or more.
