−接合構造体の構成−
まず、本発明の第１実施形態の接合構造体１について説明する。 −Composition structure−
First, the bonded structure 1 according to the first embodiment of the present invention will be described.

本実施形態の接合構造体１は、第１部材２と、第２部材３と、が接合領域ＢＦで接合され、第２部材３には、第１部材２と係合させることにより、接合領域ＢＦで、第２部材３を第１部材２に押圧させる押圧係合部３０が備えられている（例えば、図３（ａ）〜（ｃ）参照）。   In the joint structure 1 of the present embodiment, the first member 2 and the second member 3 are joined in the joint region BF, and the second member 3 is engaged with the first member 2 to thereby join the joint region. A pressing engagement portion 30 that presses the second member 3 against the first member 2 by the BF is provided (see, for example, FIGS. 3A to 3C).

第１部材２は金属であり、金属の一例としては、鉄系金属、ステンレス系金属、銅系金属、アルミ系金属、マグネシウム系金属、および、それらの合金が挙げられる。また、金属成型体であってもよく、亜鉛ダイカスト、アルミダイカスト、粉末冶金などであってもよい。   The first member 2 is a metal, and examples of the metal include iron metal, stainless steel metal, copper metal, aluminum metal, magnesium metal, and alloys thereof. Moreover, a metal molding may be sufficient and zinc die-casting, aluminum die-casting, powder metallurgy, etc. may be sufficient.

第１部材２（金属）には、貫通孔２３が形成されている（例えば、図１参照）。貫通孔２３の開口径の大きさは、後述する第２部材３（可撓性の樹脂）の押圧係合部３０を挿入させることが可能な程度である。また、貫通孔２３の形状は、押圧係合部３０が挿入されて第２部材３を第１部材２に押圧させるため、押圧力を均等にする観点から円形状が好ましいが、この形状に限られるものではない。   A through hole 23 is formed in the first member 2 (metal) (see, for example, FIG. 1). The size of the opening diameter of the through hole 23 is such that a pressing engagement portion 30 of a second member 3 (flexible resin) described later can be inserted. In addition, the shape of the through hole 23 is preferably a circular shape from the viewpoint of equalizing the pressing force because the pressing engagement portion 30 is inserted and the second member 3 is pressed against the first member 2, but the shape is limited to this shape. Is not something

第１部材２の表面の貫通孔２３の周囲は、接合領域ＢＦとされており、接合領域ＢＦには、開口を有する凹状部２１が複数形成されている（例えば、図３（ａ）、（ｂ）参照）。図示例では、凹状部２１は、断面的に見てほぼ円形の非貫通孔であるが、この形状に限定されるものではない。   The periphery of the through hole 23 on the surface of the first member 2 is a bonding region BF, and a plurality of concave portions 21 having openings are formed in the bonding region BF (for example, FIG. b)). In the illustrated example, the concave portion 21 is a non-through hole having a substantially circular shape when viewed in cross section, but is not limited to this shape.

凹状部２１の開口径は、３０μｍ以上、１００μｍ以下が好ましい。これは、開口径が３０μｍを下回ると、後述する接合工程において、照射された接合用のレーザが凹状部２１内に十分に閉じ込められず、接合用のレーザのエネルギーを熱に変換する変換効率が低下する場合があるためである。一方、開口径が１００μｍを上回ると、単位面積あたりの凹状部２１の数が減少して、接合用のレーザのエネルギーを熱に変換する変換効率が低下する場合があるためである。また、凹状部２１の深さは、１０μｍ以上であることが好ましい。これは、深さが１０μｍを下回ると、接合用のレーザのエネルギーを熱に変換する変換効率が低下する場合があるためである。   The opening diameter of the concave portion 21 is preferably 30 μm or more and 100 μm or less. This is because when the opening diameter is less than 30 μm, the irradiated bonding laser is not sufficiently confined in the concave portion 21 in the bonding step described later, and the conversion efficiency for converting the energy of the bonding laser into heat is increased. This is because it may decrease. On the other hand, when the opening diameter exceeds 100 μm, the number of the concave portions 21 per unit area decreases, and the conversion efficiency for converting the energy of the laser for bonding into heat may decrease. Moreover, it is preferable that the depth of the recessed part 21 is 10 micrometers or more. This is because if the depth is less than 10 μm, the conversion efficiency for converting the energy of the laser for bonding into heat may decrease.

また、凹状部２１の間隔（所定の凹状部２１の中心と、所定の凹状部２１と隣接する凹状部２１の中心との距離）は、２００μｍ以下であることが好ましい。これは、凹状部２１の間隔が２００μｍを上回ると、単位面積あたりの凹状部２１の数が減少して、接合用のレーザのエネルギーを熱に変換する変換効率が低下する場合があるためである。なお、凹状部２１の間隔の下限の一例としては、凹状部２１が重畳して潰れない距離である。また、凹状部２１の間隔は等間隔であることが好ましい。これは、凹状部２１が等間隔であると、接合用のレーザが照射される際の熱の分布が等方的になるためである。   The interval between the concave portions 21 (the distance between the center of the predetermined concave portion 21 and the center of the concave portion 21 adjacent to the predetermined concave portion 21) is preferably 200 μm or less. This is because if the interval between the concave portions 21 exceeds 200 μm, the number of the concave portions 21 per unit area decreases, and the conversion efficiency for converting the energy of the laser for bonding into heat may decrease. . An example of the lower limit of the interval between the concave portions 21 is a distance at which the concave portions 21 are not overlapped and crushed. Moreover, it is preferable that the space | interval of the recessed part 21 is equal intervals. This is because when the concave portions 21 are equidistant, the heat distribution when the bonding laser is irradiated is isotropic.

凹状部２１には、後述する第２部材３が充填されることにより、第１部材２と第２部材３とが接合される。ここで、本実施形態の凹状部２１には、内側に突出する突出部２２が形成されている。このように凹状部２１の内周面に、内側に突出する突出部２２が形成されている場合は、凹状部２１に第２部材３が充填されると、突出部２２によるアンカー効果によって第１部材２と第２部材３との接合強度を高めることができる。なお、凹状部２１に突出部２２が形成されていなくてもよい。   The first member 2 and the second member 3 are joined to each other by filling the concave portion 21 with a second member 3 described later. Here, the concave portion 21 of the present embodiment is formed with a protruding portion 22 that protrudes inward. Thus, when the protrusion part 22 which protrudes inside is formed in the internal peripheral surface of the recessed part 21, if the 2nd member 3 is filled into the recessed part 21, it will be 1st according to the anchor effect by the protrusion part 22. The bonding strength between the member 2 and the second member 3 can be increased. Note that the protrusion 22 may not be formed in the concave portion 21.

Further, it may be FRP (fiber reinforced plastic).

なお、熱可塑性樹脂および熱硬化性樹脂には、充填剤が添加されていてもよい。充填剤の一例としては、無機系充填剤（ガラス繊維、無機塩類など）、金属系充填剤、有機系充填剤、および、炭素繊維などが挙げられる。   Note that a filler may be added to the thermoplastic resin and the thermosetting resin. Examples of the filler include inorganic fillers (glass fibers, inorganic salts, etc.), metal fillers, organic fillers, and carbon fibers.

第２部材３には、第１部材２と係合させることにより、接合領域ＢＦで第２部材３を第１部材２に押圧させる押圧係合部３０が備えられている（例えば図１参照）。本実施形態では、押圧係合部３０が、第２部材３の中央付近に突設されているが、押圧係合部３０が突設されている位置は、この例に限られない。また、押圧係合部３０の数も１個に限られるものではなく、複数形成されていてもよい。   The second member 3 is provided with a pressing engagement portion 30 that engages with the first member 2 to press the second member 3 against the first member 2 in the joining region BF (see, for example, FIG. 1). . In the present embodiment, the pressing engagement portion 30 protrudes near the center of the second member 3, but the position where the pressing engagement portion 30 protrudes is not limited to this example. Further, the number of the press engagement portions 30 is not limited to one, and a plurality of the press engagement portions 30 may be formed.

押圧係合部３０は、第１部材２と係合する鉤部３２と、鉤部３２と第２部材３とを結ぶ連結部３１と、から構成されている。   The pressing engagement portion 30 includes a flange portion 32 that engages with the first member 2 and a connecting portion 31 that connects the flange portion 32 and the second member 3.

鉤部３２は、押圧係合部３０を貫通孔２３に挿入する際に、挿入しやすくガイドするものであり、図示例では、円錐形状である（図３（ａ）参照）。また、図示例の鉤部３２の長さＬＦは、接合領域ＢＦの領域長と、略等しく設計されている。すなわち、押圧係合部３０が第１部材２の裏面と接触している領域の領域長は、接合領域ＢＦの領域長と、略等しく設計されている。   The flange portion 32 is a guide for easy insertion when the pressing engagement portion 30 is inserted into the through hole 23, and has a conical shape in the illustrated example (see FIG. 3A). In addition, the length LF of the collar portion 32 in the illustrated example is designed to be substantially equal to the region length of the bonding region BF. That is, the region length of the region where the pressing engagement portion 30 is in contact with the back surface of the first member 2 is designed to be substantially equal to the region length of the joining region BF.

鉤部３２の角部ｒは丸角とされている。このように、鉤部３２の角部ｒを丸角とすることにより、角部が鋭角である場合と比較して、角部のバリの影響、成型制度の影響（角部の形状出来栄え、つまり均等な押圧に必要な平面度に関する精度）等による押圧ばらつきを減少することができる。すなわち、後述する接合構造体１の製造方法の押圧係合工程において、第２部材３を第１部材２に押圧させやすくすることができる。   The corner portion r of the collar portion 32 is a round corner. In this way, by making the corner portion r of the collar portion 32 round, as compared with the case where the corner portion is an acute angle, the influence of the burr of the corner portion, the influence of the molding system (the shape of the corner portion is excellent, that is, It is possible to reduce pressing variation due to flatness necessary for uniform pressing. That is, it is possible to easily press the second member 3 against the first member 2 in the pressing engagement step of the manufacturing method of the joined structure 1 described later.

連結部３１は、貫通孔２３と密着するものであり、図示例では、円柱形状である。連結部３１の長さｌは、第１部材２の厚みｔよりも短く設計されている（例えば、図１参照）。すなわち、押圧係合部３０における、第２部材３からの突設位置から第１部材２の裏面と接触される位置までの長さｌは、第１部材２の厚みｔよりも短く設計されている。   The connecting portion 31 is in close contact with the through hole 23 and has a cylindrical shape in the illustrated example. The length l of the connecting portion 31 is designed to be shorter than the thickness t of the first member 2 (see, for example, FIG. 1). That is, the length l from the protruding position from the second member 3 to the position where the pressing engagement portion 30 contacts the back surface of the first member 2 is designed to be shorter than the thickness t of the first member 2. Yes.

なお、押圧係合部３０の形状は、図４に示すように押圧係合部３０の中央部が割れている割ピン形状や、図５に示すように鉤部３２が平頭のリベット形状であってもよい。   The shape of the press engagement portion 30 is a split pin shape in which the center portion of the press engagement portion 30 is broken as shown in FIG. 4 or a rivet shape in which the collar portion 32 is flat head as shown in FIG. May be.

なお、本実施形態では、第１部材２を、金属として説明したが、この例に限られず、熱可塑性樹脂、又は、熱硬化樹脂としてもよい。第１部材２に熱可塑性樹脂、又は、熱硬化性樹脂を用いた場合は、後述する接合構造体１の製造方法の接合工程において、接合領域ＢＦに向けてレーザを照射した際に、第１部材２及び第２部材３が互いに溶融されて接合されるため、第１部材２に凹状部２１を設けなくても第１部材２と第２部材３とを接合することができる。なお、第１部材２に熱可塑性樹脂、又は、熱硬化樹脂を用いた場合であっても凹状部２１を設けてもよく、凹状部２１に突出部２２を設けた場合は、アンカー効果により、より強固に第１部材２と第２部材３とを接合することができる。   In the present embodiment, the first member 2 has been described as a metal, but is not limited to this example, and may be a thermoplastic resin or a thermosetting resin. When a thermoplastic resin or a thermosetting resin is used for the first member 2, when the laser is irradiated toward the bonding region BF in the bonding step of the manufacturing method of the bonded structure 1 described later, Since the member 2 and the second member 3 are melted and joined to each other, the first member 2 and the second member 3 can be joined without providing the first member 2 with the concave portion 21. In addition, even if it is a case where a thermoplastic resin or a thermosetting resin is used for the 1st member 2, you may provide the recessed part 21, and when the recessed part 21 is provided with the protrusion part 22, by an anchor effect, The first member 2 and the second member 3 can be joined more firmly.

−接合構造体の製造方法−
次に、本実施形態に係る接合構造体１の製造方法について説明する。 -Manufacturing method of bonded structure-
Next, a method for manufacturing the bonded structure 1 according to the present embodiment will be described.

本実施形態に係る接合構造体１の製造方法は、凹状部形成工程と、押圧係合工程と、接合工程と、を備える。以下、各工程について説明する。   The manufacturing method of the junction structure 1 according to the present embodiment includes a concave portion forming step, a pressing engagement step, and a joining step. Hereinafter, each step will be described.

・凹状部形成工程
凹状部形成工程は、第１部材２の表面の接合領域ＢＦに、第２部材３が充填される凹状部２１を形成する工程である。なお、本実施形態では、第１部材２を金属とし、第２部材３を樹脂として説明する。 -Recessed part formation process A recessed part formation process is a process of forming the recessed part 21 with which the 2nd member 3 is filled in the joining area | region BF of the surface of the 1st member 2. As shown in FIG. In the present embodiment, the first member 2 will be described as a metal, and the second member 3 will be described as a resin.

凹状部２１は、レーザ加工処理、ブラスト処理、サンドペーパ処理、陽極酸化処理、放電加工処理、エッチング処理、およびプレス加工処理等の方法で形成される。本実施形態では、レーザ加工処理によって凹状部２１を形成する方法について詳述する。   The concave portion 21 is formed by a method such as laser processing, blast processing, sandpaper processing, anodizing processing, electric discharge processing, etching processing, or press processing. In the present embodiment, a method for forming the concave portion 21 by laser processing will be described in detail.

凹状部２１を形成する加工用レーザの種類としては、パルス発振が可能なものが好ましく、ファイバレーザ、ＹＡＧレーザ、ＹＶＯ4レーザ、半導体レーザ、炭酸ガスレーザ、エキシマレーザが選択でき、レーザの波長を考慮すると、ファイバレーザ、ＹＡＧレーザ、ＹＡＧレーザの第２高調波、ＹＶＯ4レーザ、半導体レーザが好ましい。凹状部２１は、断面的に見てほぼ円形の非貫通孔であり、第１部材２の表面に複数形成される（例えば、図３（ｂ）参照）。 The type of processing laser that forms the concave portion 21 is preferably a laser capable of pulse oscillation, and can be selected from a fiber laser, a YAG laser, a YVO 4 laser, a semiconductor laser, a carbon dioxide gas laser, and an excimer laser, and considers the wavelength of the laser. Then, a fiber laser, a YAG laser, a second harmonic of a YAG laser, a YVO 4 laser, and a semiconductor laser are preferable. The concave portion 21 is a non-through hole having a substantially circular shape when viewed in cross section, and a plurality of the concave portions 21 are formed on the surface of the first member 2 (for example, see FIG. 3B).

凹状部２１を形成する装置の一例としては、オムロン製のファイバレーザマーカＭＸＺ２０００又はＭＸ−Ｚ２０５０を挙げることができる。このファイバレーザマーカでは、１パルスが複数のサブパルスで構成されるレーザを照射することが可能である。このため、レーザのエネルギーを深さ方向に集中させやすいので、凹状部２１を形成するのに好適である。   As an example of an apparatus for forming the concave portion 21, there can be mentioned a fiber laser marker MXZ2000 or MX-Z2050 manufactured by OMRON. With this fiber laser marker, it is possible to irradiate a laser where one pulse is composed of a plurality of subpulses. For this reason, the energy of the laser is easily concentrated in the depth direction, which is suitable for forming the concave portion 21.

具体的には、第１部材２にレーザが照射されると、第１部材２が局部的に溶融されることにより凹状部２１の形成が進行する。このとき、レーザが複数のサブパルスで構成されているため、溶融された第１部材２が飛散されにくく、凹状部２１の近傍に堆積されやすい。そして、凹状部２１の形成が進行すると、溶融された第１部材２が凹状部２１の内部に堆積されることにより、凹状部２１の内周面に、内側に突出する突出部２２が形成される。   Specifically, when the first member 2 is irradiated with a laser, the first member 2 is locally melted, so that the formation of the concave portion 21 proceeds. At this time, since the laser is composed of a plurality of sub-pulses, the melted first member 2 is difficult to be scattered and easily deposited in the vicinity of the concave portion 21. Then, as the formation of the concave portion 21 proceeds, the melted first member 2 is deposited inside the concave portion 21, thereby forming the protruding portion 22 protruding inward on the inner peripheral surface of the concave portion 21. The

なお、上記ファイバレーザマーカによる加工条件としては、サブパルスの１周期が１５ｎｓ以下であることが好ましい。これは、サブパルスの１周期が１５ｎｓを超えると、熱伝導によりエネルギーが拡散しやすくなり、突出部２２を有する凹状部２１を形成しにくくなるためである。なお、サブパルスの１周期は、サブパルスの１回分の照射時間と、そのサブパルスの照射が終了されてから次回のサブパルスの照射が開始されるまでの間隔との合計時間である。   As a processing condition by the fiber laser marker, it is preferable that one period of the sub-pulse is 15 ns or less. This is because when one period of the sub-pulse exceeds 15 ns, energy is easily diffused by heat conduction, and it becomes difficult to form the concave portion 21 having the protruding portion 22. Note that one cycle of the subpulse is a total time of the irradiation time for one subpulse and the interval from the end of the irradiation of the subpulse to the start of the irradiation of the next subpulse.

また、上記ファイバレーザマーカによる加工条件としては、１パルスのサブパルス数は、２以上５０以下であることが好ましい。これは、サブパルス数が５０を超えると、サブパルスの単位あたりの出力が小さくなり、突出部２２を有する凹状部２１を形成しにくくなるためである。   Further, as a processing condition by the fiber laser marker, the number of subpulses of one pulse is preferably 2 or more and 50 or less. This is because if the number of subpulses exceeds 50, the output per unit of subpulses becomes small, and it becomes difficult to form the concave portion 21 having the protruding portions 22.

・押圧係合工程
押圧係合工程は、第１部材２の表面と第２部材３とを隣接配置させるとともに、押圧係合部３０によって第２部材３を第１部材２に押圧させる工程である。 Press Engagement Step The press engagement step is a step of placing the surface of the first member 2 and the second member 3 adjacent to each other and pressing the second member 3 against the first member 2 by the press engagement portion 30. .

具体的には、第１部材２に設けられた貫通孔２３に、押圧係合部３０の鉤部３２を弾性変形させながら挿入する。ここで、上述したとおり、本実施形態（図２参照）では、長さｌは、第１部材２の厚みｔよりも短く設計されており、押圧係合部３０を貫通孔２３に挿入すると、第２部材３の上面が凹面となるように撓んで弾性変形されるので、長さｌと厚みｔの差分に起因する押圧力を、第２部材３は第１部材２に対して掛けることができる。   Specifically, the flange portion 32 of the press engagement portion 30 is inserted into the through hole 23 provided in the first member 2 while being elastically deformed. Here, as described above, in this embodiment (see FIG. 2), the length l is designed to be shorter than the thickness t of the first member 2, and when the pressing engagement portion 30 is inserted into the through hole 23, Since the upper surface of the second member 3 is bent and elastically deformed so as to be a concave surface, the second member 3 can apply a pressing force due to the difference between the length l and the thickness t to the first member 2. it can.

なお、押圧係合部３０の鉤部の長さＬＦは、接合領域ＢＦの領域長と、略等しい。   Note that the length LF of the flange portion of the press engagement portion 30 is substantially equal to the region length of the joining region BF.

以上により、第２部材３と第１部材２とを押圧係合させることができる。   Thus, the second member 3 and the first member 2 can be pressed and engaged.

・接合工程
接合工程は、接合領域ＢＦにレーザを照射して、第１部材２と第２部材３とを互いに接合する工程である。具体的には、配置工程において、第１部材２と第２部材３とを押圧して接触させた後、接合用のレーザを第１部材２の表面に向けて照射する。 -Joining process A joining process is a process of irradiating the joining area BF with a laser to join the first member 2 and the second member 3 together. Specifically, in the arranging step, the first member 2 and the second member 3 are pressed and brought into contact with each other, and then a bonding laser is irradiated toward the surface of the first member 2.

ここで、レーザ照射は、第２部材３（樹脂）がレーザ透過性を有する場合は、第２部材３側からレーザを照射してもよいし、第１部材２（金属）側からレーザを照射してもよい。一方で、第２部材３（樹脂）がレーザ透過性を有しない場合は、第１部材２（金属）側からレーザを照射する。なお、接合用のレーザの種類としては、ファイバレーザ、ＹＡＧレーザ、ＹＶＯ4レーザ、半導体レーザ、炭酸ガスレーザ、エキシマレーザが選択できる。 Here, when the second member 3 (resin) has laser transparency, the laser irradiation may be performed by irradiating the laser from the second member 3 side or irradiating the laser from the first member 2 (metal) side. May be. On the other hand, when the 2nd member 3 (resin) does not have laser transmittance, a laser is irradiated from the 1st member 2 (metal) side. As the type of laser for bonding, fiber laser, YAG laser, YVO 4 laser, a semiconductor laser, carbon dioxide laser, an excimer laser can be selected.

レーザを第１部材２の接合領域ＢＦに照射することにより、レーザのエネルギーが第１部材２で熱に変換され、第１部材２の表面の温度が高くなる。これにより、第１部材２の表面近傍の第２部材３が溶融され、その第２部材３が凹状部２１に充填される。これとともに、前述した押圧係合工程で弾性変形している第２部材３は、第２部材３の溶融により弾性変形が緩和される。すなわち、第２部材３の上面の凹面形状が緩和される。   By irradiating the bonding region BF of the first member 2 with the laser, the energy of the laser is converted into heat by the first member 2 and the temperature of the surface of the first member 2 is increased. Thereby, the second member 3 in the vicinity of the surface of the first member 2 is melted, and the second member 3 is filled in the concave portion 21. At the same time, the elastic deformation of the second member 3 that has been elastically deformed in the above-described pressing engagement process is relaxed by the melting of the second member 3. That is, the concave shape of the upper surface of the second member 3 is relaxed.

その後、第２部材３が固化されることにより、第２部材３が第１部材２に接合された接合構造体１を製造できる（図３（ａ）参照）。   Then, the 2nd member 3 is solidified, and the joining structure 1 with which the 2nd member 3 was joined to the 1st member 2 can be manufactured (refer Fig.3 (a)).

ここで、第１部材２の接合領域ＢＦにレーザを照射する際に、接合領域ＢＦ内においてレーザを走査させるとともに、前記走査を同一軌跡で複数回行ってもよい。この場合は、レーザの走査を同一軌跡で複数回行われるため、第１部材２の温度が上昇し、より効果的に第２部材３と第１部材２とを接合することができる。   Here, when irradiating the bonding region BF of the first member 2 with the laser, the laser may be scanned in the bonding region BF, and the scanning may be performed a plurality of times along the same locus. In this case, since the laser scanning is performed a plurality of times along the same locus, the temperature of the first member 2 rises, and the second member 3 and the first member 2 can be joined more effectively.

なお、本実施形態では、第１部材２を、金属として説明したが、この例に限られず、熱可塑性樹脂、又は、熱硬化樹脂としてもよい。第１部材２に熱可塑性樹脂、又は、熱硬化性樹脂を用いた場合は、接合工程において接合領域ＢＦに向けてレーザを照射した際に、第１部材２及び第２部材３が互いに溶融して接合されるため、第１部材２に凹状部２１を設けなくても第１部材２と第２部材３とを接合することができる（すなわち、凹状部形成工程を行わなくてもよい）。なお、第１部材２に凹状部２１を設けた場合（すなわち、凹状形成工程を行った後に、押圧係合工程及び接合工程を行った場合）は、アンカー効果により、より強固に第１部材２と第２部材３とを接合することができる。   In the present embodiment, the first member 2 has been described as a metal, but is not limited to this example, and may be a thermoplastic resin or a thermosetting resin. When a thermoplastic resin or a thermosetting resin is used for the first member 2, the first member 2 and the second member 3 are melted together when the laser is irradiated toward the bonding region BF in the bonding process. Therefore, the first member 2 and the second member 3 can be joined without providing the concave portion 21 on the first member 2 (that is, the concave portion forming step may not be performed). In addition, when the recessed part 21 is provided in the 1st member 2 (namely, when a press engagement process and a joining process are performed after performing a recessed shape formation process), the 1st member 2 is more firmly by an anchor effect. And the second member 3 can be joined.

The joint structure 1 includes a pressing engagement portion 30 ′ that presses the second member 3 against the first member 2 by BF. In this embodiment, the pressing engagement portion 30 ′ is the first member 2. It contacts and engages with the outer peripheral part of the back surface.

第１部材２は金属であり、第１部材２の外周端部（第１部材２の表面の接合領域ＢＦ）には、第１部材２の表面に開口を有する凹状部２１が形成されている（例えば、図９参照）。図示例では、凹状部２１は、断面的に見てほぼ円形の非貫通孔であるが、この形状に限定されるものではない。   The first member 2 is a metal, and a concave portion 21 having an opening on the surface of the first member 2 is formed at the outer peripheral end of the first member 2 (joining region BF on the surface of the first member 2). (See, for example, FIG. 9). In the illustrated example, the concave portion 21 is a non-through hole having a substantially circular shape when viewed in cross section, but is not limited to this shape.

第２部材３は、熱可塑性樹脂、又は、熱硬化性樹脂であり、第１部材２と係合させることにより、接合領域ＢＦで第２部材３を第１部材２に押圧させる押圧係合部３０´が備えられている。本実施形態では、第２部材３の外周端部に押圧係合部３０´が形成されている。   The second member 3 is a thermoplastic resin or a thermosetting resin, and is engaged with the first member 2, thereby pressing the second member 3 against the first member 2 in the joining region BF. 30 'is provided. In the present embodiment, a pressing engagement portion 30 ′ is formed at the outer peripheral end portion of the second member 3.

押圧係合部３０´は、第１部材２と係合する鉤部３２´と、鉤部３２´と第２部材３とを結ぶ連結部３１´と、から構成されている。   The pressing engagement portion 30 ′ is composed of a flange portion 32 ′ that engages with the first member 2 and a connecting portion 31 ′ that connects the flange portion 32 ′ and the second member 3.

鉤部３２´は、第１部材２の裏面外周部と当接するものである（図７及び図９参照）。図示例の鉤部３２´の長さＬＦは、接合領域ＢＦの領域長と、略等しく設計されている。すなわち、押圧係合部３０´が第１部材２の裏面と接触している領域の領域長は、接合領域ＢＦの領域長と、略等しく設計されている。   The collar portion 32 ′ is in contact with the outer peripheral portion of the back surface of the first member 2 (see FIGS. 7 and 9). The length LF of the flange portion 32 'in the illustrated example is designed to be substantially equal to the region length of the bonding region BF. That is, the region length of the region where the press engagement portion 30 ′ is in contact with the back surface of the first member 2 is designed to be substantially equal to the region length of the joining region BF.

連結部３１´は、第１部材２の側面と当接するものである（図７及び図９参照）。図示例では、連結部３１´の長さｌは、第１部材２の厚みｔよりも短く設計されている。すなわち、押圧係合部３０´における、第２部材３からの突設位置から第１部材２の裏面と接触される位置までの長さｌは、第１部材２の厚みｔよりも短く設計されている。   The connecting portion 31 ′ is in contact with the side surface of the first member 2 (see FIGS. 7 and 9). In the illustrated example, the length l of the connecting portion 31 ′ is designed to be shorter than the thickness t of the first member 2. That is, the length l from the protruding position from the second member 3 to the position in contact with the back surface of the first member 2 in the pressing engagement portion 30 ′ is designed to be shorter than the thickness t of the first member 2. ing.

なお、本実施形態では、第１部材２を、金属として説明したが、この例に限られず、熱可塑性樹脂、又は、熱硬化樹脂としてもよい。第１部材２に熱可塑性樹脂、又は、熱硬化性樹脂を用いた場合は、後述する接合構造体の製造方法の接合工程において、第１部材２及び第２部材３の接合領域ＢＦに向けてレーザを照射した場合、第１部材２及び第２部材３が互いに溶融されて接合されるため、第１部材２に凹状部２１を設けなくても第１部材２と第２部材３とを接合することができる。なお、第１部材２に凹状部２１を設けた場合は、アンカー効果により、より強固に第１部材２と第２部材３とを接合することができる。   In the present embodiment, the first member 2 has been described as a metal, but is not limited to this example, and may be a thermoplastic resin or a thermosetting resin. When a thermoplastic resin or a thermosetting resin is used for the first member 2, in the bonding step of the method for manufacturing the bonded structure described later, toward the bonding region BF of the first member 2 and the second member 3. When the laser is irradiated, the first member 2 and the second member 3 are melted and joined to each other, so that the first member 2 and the second member 3 can be joined without providing the first member 2 with the concave portion 21. can do. In addition, when the recessed part 21 is provided in the 1st member 2, the 1st member 2 and the 2nd member 3 can be joined more firmly by an anchor effect.

−接合構造体の製造方法−
次に、本実施形態に係る接合構造体１の製造方法について説明する。 -Manufacturing method of bonded structure-
Next, a method for manufacturing the bonded structure 1 according to the present embodiment will be described.

本実施形態に係る接合構造体の製造方法は、凹状部形成工程と、押圧係合工程と、接合工程と、を備える。以下、各工程について説明する。   The manufacturing method of the junction structure concerning this embodiment is provided with a concave part formation process, a press engagement process, and a joining process. Hereinafter, each step will be described.

・凹状部形成工程
凹状部形成工程により、第１部材２の接合領域ＢＦに、第２部材３が充填される凹状部２１を形成する。上述したとおり、本実施形態では、凹状部２１は、第１部材２の表面の外周端部に形成する。このとき、レーザが複数のサブパルスで構成されている場合は、凹状部２１の内周面に、内側に突出する突出部２２を形成できる。 -Concave part formation process The concave part 21 with which the 2nd member 3 is filled is formed in joining area | region BF of the 1st member 2 by a concave part formation process. As described above, in the present embodiment, the concave portion 21 is formed at the outer peripheral end portion of the surface of the first member 2. At this time, when the laser is composed of a plurality of sub-pulses, the protruding portion 22 protruding inward can be formed on the inner peripheral surface of the concave portion 21.

・押圧係合工程
押圧係合工程により、第１部材２の表面と第２部材３とを隣接配置させるとともに、押圧係合部３０によって第２部材３を第１部材２に押圧させる。 Press Engagement Step In the press engagement step, the surface of the first member 2 and the second member 3 are disposed adjacent to each other, and the second member 3 is pressed against the first member 2 by the press engagement portion 30.

具体的には、鉤部３２´を弾性変形させながら第１部材２の裏面の外周端部に当接させる。ここで、上述したとおり、本実施形態（図８参照）では、長さｌは、第１部材２の厚みｔよりも短く設計されており、押圧係合部３０´を第１部材２の裏面の外周端部に当接させると、第２部材３の上面が凸面となるように撓んで弾性変形されるので、長さｌと厚みｔの差分に起因する押圧力を、第２部材３は第１部材２に対して掛けることができる。   Specifically, the collar portion 32 ′ is brought into contact with the outer peripheral end portion of the back surface of the first member 2 while being elastically deformed. Here, as described above, in the present embodiment (see FIG. 8), the length l is designed to be shorter than the thickness t of the first member 2, and the pressing engagement portion 30 ′ is connected to the back surface of the first member 2. Since the upper surface of the second member 3 is bent and elastically deformed so that the upper surface of the second member 3 becomes a convex surface, the second member 3 applies the pressing force due to the difference between the length l and the thickness t. It can be hung on the first member 2.

以上により、第２部材３と第１部材２とを押圧係合させることができる。   Thus, the second member 3 and the first member 2 can be pressed and engaged.

・接合工程
接合工程により、接合領域ＢＦにレーザを照射して、第１部材２と第２部材３とを互いに接合する。 -Joining process In the joining process, the first member 2 and the second member 3 are joined to each other by irradiating the joining region BF with laser.

レーザを第１部材２の接合領域ＢＦに照射することにより、第１部材２の表面近傍の第２部材３が溶融され、その第２部材３が凹状部２１に充填される。これとともに、前述した押圧係合工程で弾性変形している第２部材３は、第２部材３の溶融により弾性変形が緩和される。すなわち、第２部材３の上面の凸面形状が緩和される。   By irradiating the bonding region BF of the first member 2 with the laser, the second member 3 in the vicinity of the surface of the first member 2 is melted, and the second member 3 is filled in the concave portion 21. At the same time, the elastic deformation of the second member 3 that has been elastically deformed in the above-described pressing engagement process is relaxed by the melting of the second member 3. That is, the convex shape of the upper surface of the second member 3 is relaxed.

その後、第２部材３が固化されることにより、第２部材３が第１部材２に接合された接合構造体１を製造できる（図９参照）。   Then, the 2nd member 3 is solidified and the junction structure 1 with which the 2nd member 3 was joined to the 1st member 2 can be manufactured (refer FIG. 9).

なお、本実施形態では、第１部材２を、金属として説明したが、この例に限られず、熱可塑性樹脂、又は、熱硬化樹脂としてもよい。第１部材２に熱可塑性樹脂、又は、熱硬化性樹脂を用いた場合は、接合工程において、第１部材２及び第２部材３の接合領域ＢＦに向けてレーザを照射した際に、第１部材２及び第２部材３が互いに溶融して接合されるため、第１部材２に凹状部２１を設けなくても第１部材２と第２部材３とを接合することができる（すなわち、凹状部形成工程を行わなくてもよい）。なお、第１部材２に凹状部２１を設けた場合（すなわち、凹状形成工程を行った後に、押圧係合工程及び接合工程を行った場合）は、アンカー効果により、より強固に第１部材２と第２部材３とを接合することができる。   In the present embodiment, the first member 2 has been described as a metal, but is not limited to this example, and may be a thermoplastic resin or a thermosetting resin. When a thermoplastic resin or a thermosetting resin is used for the first member 2, the first member 2 and the second member 3 are irradiated with a laser toward the bonding region BF in the bonding step. Since the member 2 and the second member 3 are melted and joined to each other, the first member 2 and the second member 3 can be joined without providing the concave portion 21 in the first member 2 (that is, the concave shape). It is not necessary to perform the part forming step). In addition, when the recessed part 21 is provided in the 1st member 2 (namely, when a press engagement process and a joining process are performed after performing a recessed shape formation process), the 1st member 2 is more firmly by an anchor effect. And the second member 3 can be joined.

In the joining structure 100 ′ of Example 2-2, the first member 200 ′ is made of PBT, the second member 300 ′ is made of PMMA resin, and the second member 300 ′ is engaged with the first member 200 ′. Accordingly, a pressing engagement portion 310 ′ (width 5 mm, length 15 mm) that presses the second member 300 ′ against the first member 200 ′ is provided.

また、凹状部形成工程において第１部材２００´に凹状部を形成し、押圧係合工程によって第２部材３００´を第１部材２００´に押圧させ、接合工程において接合領域ＢＦ２にレーザを照射することにより、第１部材２００´の凹状部に第２部材３００´を充填させて、第１部材２００´と第２部材３００´とを接合領域ＢＦ２で接合させた。   In addition, a concave portion is formed in the first member 200 ′ in the concave portion forming step, the second member 300 ′ is pressed against the first member 200 ′ in the pressing engagement step, and the bonding region BF2 is irradiated with a laser in the bonding step. Thus, the concave portion of the first member 200 ′ was filled with the second member 300 ′, and the first member 200 ′ and the second member 300 ′ were joined in the joining region BF2.

この接合構造体１００´を、せん断方向（水平方向）に引張速度５ｍｍ／ｍｉｎで試験を行った結果、第１部材２００´と第２部材３００´とは剥離しなかった。   As a result of testing this bonded structure 100 ′ in the shear direction (horizontal direction) at a tensile speed of 5 mm / min, the first member 200 ′ and the second member 300 ′ were not peeled off.

以上、説明したとおり、第２部材３００´には、押圧係合部３１０´が備えられているので、押圧係合工程により、第２部材３００´を第１部材２００´に押圧させることができ、その後の接合工程によって、接合領域ＢＦ２にレーザを照射して第１部材２００´と第２部材３００´とが互いに位置決めされた状態で接合することができる。これにより、従来技術と異なり、接圧治具等の押圧装置を用いずに、第２部材３００´と第１部材２００´とを押圧させた状態で精度よく第１部材２００´と第２部材３００´とを接合することができる。   As described above, the second member 300 ′ is provided with the pressing engagement portion 310 ′, so that the second member 300 ′ can be pressed against the first member 200 ′ by the pressing engagement step. In the subsequent joining step, the joining region BF2 can be irradiated with a laser to join the first member 200 'and the second member 300' in a state where they are positioned with respect to each other. Thus, unlike the prior art, the first member 200 'and the second member are accurately obtained in a state where the second member 300' and the first member 200 'are pressed without using a pressing device such as a contact pressure jig. 300 'can be joined.

また、第２部材３００´の押圧係合部３１０´は、第１部材２００´の裏面外周部と当接して係合させるものであるので、押圧係合工程により、第１部材２００´の裏面外周部に、第２部材３００´の押圧係合部３１０´を当接させるだけで、第２部材３００´を第１部材２００´に押圧させることができる。したがって、押圧係合工程を容易に行うことができる。   Further, the press engagement portion 310 ′ of the second member 300 ′ is in contact with and engaged with the outer peripheral portion of the back surface of the first member 200 ′. The second member 300 ′ can be pressed against the first member 200 ′ simply by bringing the pressing engagement portion 310 ′ of the second member 300 ′ into contact with the outer peripheral portion. Therefore, the pressing engagement process can be easily performed.
