Description

本発明は、樹脂部材とガラス部材とを溶着して樹脂・ガラス溶着体を製造する樹脂・ガラス溶着方法及び樹脂・ガラス溶着装置に関する。   The present invention relates to a resin / glass welding method and a resin / glass welding apparatus for producing a resin / glass welded body by welding a resin member and a glass member.

従来の樹脂・ガラス溶着方法として、溶着の相性が改善されるように表面処理を実施した上で、樹脂部材とガラス部材とをレーザ溶着する方法が知られている（例えば、特許文献１参照）。
特開２００５−７４７９６号公報 As a conventional resin / glass welding method, there is known a method in which a resin member and a glass member are laser-welded after surface treatment is performed so that the compatibility of welding is improved (see, for example, Patent Document 1). .
JP-A-2005-74796

しかしながら、上述したような従来の樹脂・ガラス溶着方法には、樹脂部材とガラス部材とが一旦溶着されても、比較的短時間で分離してしまうという問題があった。   However, the conventional resin / glass welding method as described above has a problem that once the resin member and the glass member are welded, they are separated in a relatively short time.

そこで、本発明は、このような事情に鑑みてなされたものであり、樹脂部材とガラス部材との溶着の確実性が向上された樹脂・ガラス溶着体を製造することができる樹脂・ガラス溶着方法及び樹脂・ガラス溶着装置を提供することを目的とする。   Therefore, the present invention has been made in view of such circumstances, and a resin / glass welding method capable of producing a resin / glass welded body with improved reliability of welding between a resin member and a glass member. And it aims at providing the resin and glass welding apparatus.

本発明者は、上記目的を達成するために鋭意検討を重ねた結果、一旦溶着された樹脂部材とガラス部材とが比較的短時間で分離する第１の原因を突き止めた。図５は、樹脂部材とガラス部材とが分離する第１の原因を説明するための断面図である。図５に示されるように、樹脂部材Ｍ１とガラス部材Ｍ２とをレーザ溶着するに際して、環状の溶着予定領域Ｒに沿ってレーザ光Ｌを相対的に移動させると、始点として溶着された部分に終点としてレーザ光Ｌが再度照射されて溶融樹脂が膨張する。そのため、溶融樹脂の膨張圧によって始点／終点の部分での溶着強度が低下し、一旦溶着された樹脂部材Ｍ１とガラス部材Ｍ２とが比較的短時間で分離し易くなる。本発明者は、この知見に基づいて更に検討を重ね、本発明を完成させるに至った。   As a result of intensive studies in order to achieve the above object, the present inventor has found the first cause that the resin member once welded and the glass member are separated in a relatively short time. FIG. 5 is a cross-sectional view for explaining a first cause of separation of the resin member and the glass member. As shown in FIG. 5, when laser welding the resin member M1 and the glass member M2, when the laser light L is relatively moved along the annular welding scheduled region R, the end point is reached at the welded portion as the starting point. As a result, the laser beam L is irradiated again and the molten resin expands. Therefore, the welding strength at the start / end points is lowered by the expansion pressure of the molten resin, and the resin member M1 and the glass member M2 once welded are easily separated in a relatively short time. The present inventor has further studied based on this finding and has completed the present invention.

すなわち、本発明に係る樹脂・ガラス溶着方法は、樹脂部材とガラス部材とを溶着して樹脂・ガラス溶着体を製造する樹脂・ガラス溶着方法であって、シランカップリング剤によって改質されたガラス部材の表面を介して樹脂部材とガラス部材とを対向させて、ガラス部材に対する樹脂部材の対向面において樹脂部材が溶融するように、対向面おける環状の溶着予定領域に対して略同時にレーザ光を照射することを特徴とする。   That is, the resin / glass welding method according to the present invention is a resin / glass welding method for producing a resin / glass welded body by welding a resin member and a glass member, and is a glass modified by a silane coupling agent. The resin member and the glass member are opposed to each other through the surface of the member, and the laser beam is substantially simultaneously applied to the annular welding planned region on the facing surface so that the resin member melts on the facing surface of the resin member with respect to the glass member. Irradiating.

この樹脂・ガラス溶着方法では、シランカップリング剤によって改質されたガラス部材の表面を介して対向させられた樹脂部材とガラス部材との対向面において樹脂部材が溶融するように、対向面おける環状の溶着予定領域に対して略同時にレーザ光を照射する。これにより、環状の溶着予定領域において樹脂部材が略同時に溶融して再固化するため、環状の溶着予定領域の全体に渡って樹脂部材とガラス部材との溶着強度の低下を防止することができる。従って、樹脂部材とガラス部材との溶着の確実性が向上された樹脂・ガラス溶着体を製造することが可能となる。   In this resin / glass welding method, an annular ring on the opposing surface is used so that the resin member melts on the opposing surface of the glass member and the resin member opposed to each other through the surface of the glass member modified by the silane coupling agent. The laser beam is irradiated almost simultaneously on the planned welding region. Thereby, since the resin member is melted and re-solidified substantially simultaneously in the annular welding scheduled region, it is possible to prevent the welding strength between the resin member and the glass member from being lowered over the entire annular welding scheduled region. Therefore, it is possible to manufacture a resin / glass welded body with improved reliability of welding between the resin member and the glass member.

更に、本発明者は、一旦溶着された樹脂部材とガラス部材とが比較的短時間で分離する第２の原因をも突き止めた。図６は、樹脂部材とガラス部材とが分離する第２の原因を説明するための断面図である。   Furthermore, the present inventor has also found a second cause that the resin member and the glass member once welded are separated in a relatively short time. FIG. 6 is a cross-sectional view for explaining a second cause of separation of the resin member and the glass member.

図６（ａ）に示されるように、樹脂部材Ｍ１とガラス部材Ｍ２とをレーザ溶着するに際して、溶着予定領域Ｒに沿ってレーザ光Ｌを相対的に移動させると、レーザ光Ｌの照射によって樹脂部材Ｍ１が発熱して溶融し、溶融樹脂（図６におけるドット部分）が膨張してガラス部材Ｍ２に押圧される。その後、図６（ｂ）に示されるように、レーザ光Ｌの相対的な移動によって熱源が去るため、溶融樹脂が急速に収縮する。このとき、収縮応力が溶着強度より大きいと、図６（ｃ）に示されるように、溶融樹脂が再固化する際にガラス部材Ｍ２との間に隙間Ｇが形成されて、一旦溶着された樹脂部材Ｍ１とガラス部材Ｍ２とが比較的短時間で分離し易くなる。   As shown in FIG. 6A, when the resin member M1 and the glass member M2 are laser-welded, if the laser light L is relatively moved along the planned welding region R, the resin is irradiated by the laser light L. The member M1 generates heat and melts, and the molten resin (dot portions in FIG. 6) expands and is pressed against the glass member M2. Thereafter, as shown in FIG. 6B, since the heat source leaves due to the relative movement of the laser light L, the molten resin rapidly contracts. At this time, if the shrinkage stress is larger than the welding strength, as shown in FIG. 6C, a gap G is formed between the molten resin and the glass member M2 when the molten resin is re-solidified. The member M1 and the glass member M2 are easily separated in a relatively short time.

このような溶融樹脂の急速な収縮を抑制する手段として、図７（ａ）に示されるように、レーザ光Ｌの強度が低いか、或いはレーザ光Ｌの相対的な移動速度が速い場合に比べ、図７（ｂ）に示されるように、レーザ光Ｌの強度を高くしたり、或いはレーザ光Ｌの相対的な移動速度を遅くしたりして、溶融樹脂の体積を増加させる手段が考えられる。   As a means for suppressing such rapid shrinkage of the molten resin, as shown in FIG. 7A, the intensity of the laser beam L is low, or the relative movement speed of the laser beam L is high. As shown in FIG. 7B, a means for increasing the volume of the molten resin by increasing the intensity of the laser light L or slowing the relative moving speed of the laser light L can be considered. .

しかしながら、レーザ光Ｌの強度を高くすると、図８に示されるように、溶融樹脂の冷却時間が長くなって、溶融樹脂の急速な収縮が抑制されるものの、溶融樹脂の最高到達温度が高くなるため、シランカップリング剤によってガラス部材の表面に生成された官能基が分解されるおそれがある。また、レーザ光Ｌの相対的な移動速度を遅くすると、樹脂部材とガラス部材とを溶着するのに長時間を要し、樹脂・ガラス溶着体の生産性が低下してしまう。   However, when the intensity of the laser beam L is increased, as shown in FIG. 8, the time for cooling the molten resin becomes longer and the rapid shrinkage of the molten resin is suppressed, but the maximum temperature reached by the molten resin increases. Therefore, the functional group generated on the surface of the glass member by the silane coupling agent may be decomposed. If the relative moving speed of the laser beam L is slowed down, it takes a long time to weld the resin member and the glass member, and the productivity of the resin / glass welded body is lowered.

そこで、本発明に係る樹脂・ガラス溶着方法においては、レーザ光を照射するに際しては、レーザ光の強度を徐々に低くすることが好ましい。これにより、溶融樹脂の急速な収縮を抑制することができ、樹脂部材とガラス部材との溶着の確実性をより一層向上させることが可能となる。   Therefore, in the resin / glass welding method according to the present invention, it is preferable to gradually reduce the intensity of the laser beam when irradiating the laser beam. Thereby, rapid shrinkage | contraction of molten resin can be suppressed and it becomes possible to further improve the certainty of welding with a resin member and a glass member.

本発明に係る樹脂・ガラス溶着方法においては、樹脂部材とガラス部材とを対向させるに際しては、樹脂部材とガラス部材とを互いに押圧させることが好ましい。この場合、樹脂部材とガラス部材とが互いに押圧させられた状態で樹脂部材が溶融するため、樹脂部材とガラス部材との溶着強度をより一層高くすることができる。また、樹脂部材の反り等の変形が抑制されるため、樹脂部材とガラス部材とをより一層確実に溶着することができる。   In the resin / glass welding method according to the present invention, when the resin member and the glass member are opposed to each other, it is preferable to press the resin member and the glass member together. In this case, since the resin member melts in a state where the resin member and the glass member are pressed against each other, the welding strength between the resin member and the glass member can be further increased. In addition, since deformation such as warping of the resin member is suppressed, the resin member and the glass member can be more reliably welded.

本発明に係る樹脂・ガラス溶着装置は、樹脂部材とガラス部材とを溶着して樹脂・ガラス溶着体を製造する樹脂・ガラス溶着装置であって、シランカップリング剤によって改質されたガラス部材の表面を介して対向させられた樹脂部材とガラス部材とを支持する支持部と、ガラス部材に対する樹脂部材の対向面において樹脂部材が溶融するように、対向面おける環状の溶着予定領域に対して略同時にレーザ光を照射するレーザ光照射部と、を備えることを特徴とする。   The resin / glass welding apparatus according to the present invention is a resin / glass welding apparatus for manufacturing a resin / glass welded body by welding a resin member and a glass member, and is a glass member modified by a silane coupling agent. A support part that supports the resin member and the glass member that are opposed to each other through the surface, and an annular welding planned area on the facing surface so that the resin member melts on the facing surface of the resin member with respect to the glass member. And a laser beam irradiating unit that irradiates the laser beam at the same time.

本発明に係る樹脂・ガラス溶着装置は、レーザ光を照射するに際し、レーザ光の強度を徐々に低くする制御部を備えることが好ましい。   The resin / glass welding apparatus according to the present invention preferably includes a control unit that gradually decreases the intensity of the laser light when the laser light is irradiated.

この樹脂・ガラス溶着装置によれば、上述した本発明に係る樹脂・ガラス溶着方法と同様に、樹脂部材とガラス部材との溶着の確実性が向上された樹脂・ガラス溶着体を製造することができる。   According to this resin / glass welding apparatus, it is possible to produce a resin / glass welded body with improved reliability of welding between the resin member and the glass member, as in the resin / glass welding method according to the present invention described above. it can.

本発明によれば、樹脂部材とガラス部材との溶着の確実性が向上された樹脂・ガラス溶着体を製造することができる。   According to the present invention, it is possible to manufacture a resin / glass welded body with improved reliability of welding between a resin member and a glass member.

以下、本発明の好適な実施形態について、図面を参照して詳細に説明する。なお、各図において同一又は相当部分には同一符号を付し、重複する説明を省略する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In addition, in each figure, the same code | symbol is attached | subjected to the same or an equivalent part, and the overlapping description is abbreviate | omitted.

図１は、本発明に係る樹脂・ガラス溶着装置の一実施形態を示す概略構成図である。図１に示されるように、樹脂・ガラス溶着装置１は、樹脂部材Ｍ１とガラス部材Ｍ２とをレーザ溶着して樹脂・ガラス溶着体Ｐを製造する装置である。樹脂部材Ｍ１は、例えば、ポリカーボネート、ポリアミド、ポリブチレンテレフタレート、ポリフェニレンサルファイド、液晶ポリマー等からなる厚さ３ｍｍの板状の部材である。また、ガラス部材Ｍ２は、例えば、ソーダ石灰ガラス、ホウケイ酸ガラス、石英ガラス等からなる厚さ３ｍｍの板状の部材である。   FIG. 1 is a schematic configuration diagram showing an embodiment of a resin / glass welding apparatus according to the present invention. As shown in FIG. 1, the resin / glass welding apparatus 1 is an apparatus that manufactures a resin / glass weld P by laser welding a resin member M1 and a glass member M2. The resin member M1 is a plate-like member having a thickness of 3 mm made of, for example, polycarbonate, polyamide, polybutylene terephthalate, polyphenylene sulfide, liquid crystal polymer, or the like. The glass member M2 is a plate-like member having a thickness of 3 mm made of, for example, soda lime glass, borosilicate glass, quartz glass, or the like.

ガラス部材Ｍ２において樹脂部材Ｍ１と対向させられて接触させられる表面には、溶融樹脂の濡れ性を高めるために、シランカップリング剤を塗布することで官能基が生成されている。シランカップリング剤としては、例えば、３−アミノプロピルトリメトキシシラン（官能基がアミノ基である場合）や３−グリシドプロピルトリメトキシシラン（官能基がエポキシ基である場合）等を用いることができる。なお、シランカップリング剤は、ガラス部材Ｍ２の表面の水酸基に水素結合によって取り付く性質を有するため、紫外線ランプやプラズマ等によってガラス部材Ｍ２の表面を予めオゾン処理しておくのが効果的である。   A functional group is generated by applying a silane coupling agent on the surface of the glass member M2 that is opposed to and brought into contact with the resin member M1 in order to increase the wettability of the molten resin. As the silane coupling agent, for example, 3-aminopropyltrimethoxysilane (when the functional group is an amino group) or 3-glycidpropyltrimethoxysilane (when the functional group is an epoxy group) is used. it can. Since the silane coupling agent has the property of being attached to the hydroxyl group on the surface of the glass member M2 by hydrogen bonding, it is effective to pre-ozone the surface of the glass member M2 with an ultraviolet lamp or plasma.

樹脂部材Ｍ１及びガラス部材Ｍ２は、樹脂部材Ｍ１上にガラス部材Ｍ２が積層された状態で支持台（支持部）２上に載置される。つまり、支持台２は、シランカップリング剤によって改質されたガラス部材Ｍ２の表面を介して対向させられて対向させられた樹脂部材Ｍ１とガラス部材Ｍ２とを支持する。   The resin member M1 and the glass member M2 are placed on the support base (support portion) 2 in a state where the glass member M2 is laminated on the resin member M1. That is, the support base 2 supports the resin member M1 and the glass member M2 that are opposed to each other through the surface of the glass member M2 modified by the silane coupling agent.

樹脂部材Ｍ１とガラス部材Ｍ２とは、支持台２上において互いに押圧（ここでは、圧接）させられる。図２は、図１に示されたII−II線に沿っての断面図である。図２（ａ）に示されるように、レーザ光Ｌを透過する材料（ガラスや樹脂等）からなる板状の押圧部材６と支持台２との挟持によって、樹脂部材Ｍ１とガラス部材Ｍ２とを互いに押圧させてもよい。或いは、図２（ｂ）に示されるように、レーザ光Ｌを反射又は吸収する材料（金属等）からなる枠状の押圧部材６と支持台２との挟持によって、樹脂部材Ｍ１とガラス部材Ｍ２とを互いに押圧させてもよい。   The resin member M1 and the glass member M2 are pressed against each other (here, press contact) on the support base 2. FIG. 2 is a cross-sectional view taken along line II-II shown in FIG. As shown in FIG. 2A, the resin member M <b> 1 and the glass member M <b> 2 are sandwiched between the plate-like pressing member 6 made of a material that transmits the laser beam L (glass, resin, or the like) and the support base 2. You may make it press mutually. Alternatively, as shown in FIG. 2B, the resin member M1 and the glass member M2 are sandwiched between a frame-shaped pressing member 6 made of a material (such as metal) that reflects or absorbs the laser light L and the support base 2. May be pressed against each other.

図１に示されるように、支持台２の上方には、ガラス部材Ｍ２に対する樹脂部材Ｍ１の対向面（ここでは、接触面）Ｓにおいて環状に延在する溶着予定領域Ｒに沿うように光ファイバ（レーザ光照射部）Ｆ１〜Ｆ１３の先端部が配置されている。各光ファイバＦ１〜Ｆ１３の先端部は、例えばガラス製の枠部材３によって保持されている。また、各光ファイバＦ１〜Ｆ１３の基端部は、レーザ光源（レーザ光照射部）４においてレーザダイオードに光学的に接続されている。   As shown in FIG. 1, an optical fiber is provided above the support base 2 along a planned welding region R that extends in a ring shape on a facing surface (here, a contact surface) S of the resin member M1 with respect to the glass member M2. (Laser light irradiation part) The front-end | tip part of F1-F13 is arrange | positioned. The front ends of the optical fibers F1 to F13 are held by a glass frame member 3, for example. In addition, the base end portion of each of the optical fibers F <b> 1 to F <b> 13 is optically connected to a laser diode in a laser light source (laser light irradiation unit) 4.

レーザ光源４及び光ファイバＦ１〜Ｆ１３は、ガラス部材Ｍ２に対する樹脂部材Ｍ１の対向面Ｓにおいて樹脂部材Ｍ１が溶融するように、環状に延在する溶着予定領域Ｒに対して隙間なく略同時にレーザ光を照射する。つまり、各光ファイバＦ１〜Ｆ１３から出射されるレーザ光のスポットのうち隣り合うスポットの一部分は、溶着予定領域Ｒにおいて互いに重なり合っている。   The laser light source 4 and the optical fibers F <b> 1 to F <b> 13 are laser beams substantially simultaneously with no gap with respect to the annular welding planned region R so that the resin member M <b> 1 melts on the facing surface S of the resin member M <b> 1 with respect to the glass member M <b> 2. Irradiate. That is, some of the adjacent spots among the laser light spots emitted from the optical fibers F1 to F13 overlap each other in the planned welding region R.

レーザ光源４には、コントローラ（制御部）５が電気的に接続されている。コントローラ５は、レーザ光源４において各光ファイバＦ１〜Ｆ１３が光学的に接続されたレーザダイオードを制御し、各光ファイバＦ１〜Ｆ１３から出射されるレーザ光の強度を徐々に低くする。   A controller (control unit) 5 is electrically connected to the laser light source 4. The controller 5 controls the laser diode in which the optical fibers F1 to F13 are optically connected in the laser light source 4, and gradually reduces the intensity of the laser light emitted from the optical fibers F1 to F13.

図３は、図１に示された樹脂・ガラス溶着装置の各光ファイバから出射されるレーザ光の強度を示すグラフである。図３に示されるように、レーザ光の強度は、レーザ光の照射開始からの前段においては、対向面Ｓにおいて樹脂部材Ｍ１を溶融させ得る所定の強度に維持され、レーザ光の照射終了までの後段においては、徐々に低くされる。具体的には、集光スポット径１．６ｍｍ、レーザパワー８Ｗで０．３秒間レーザ光を照射した後、レーザパワーを約１秒間で０Ｗまで低下させながらレーザ光を照射する。   FIG. 3 is a graph showing the intensity of laser light emitted from each optical fiber of the resin / glass welding apparatus shown in FIG. As shown in FIG. 3, the intensity of the laser light is maintained at a predetermined intensity at which the resin member M1 can be melted on the facing surface S in the previous stage from the start of the laser light irradiation until the end of the laser light irradiation. In the latter stage, it is gradually lowered. Specifically, after irradiating a laser beam with a focused spot diameter of 1.6 mm and a laser power of 8 W for 0.3 seconds, the laser beam is irradiated while reducing the laser power to 0 W in about 1 second.

以上のように構成された樹脂・ガラス溶着装置１では、以下のような樹脂・ガラス溶着方法が実施される。   In the resin / glass welding apparatus 1 configured as described above, the following resin / glass welding method is performed.

まず、支持台２上において、シランカップリング剤によって改質されたガラス部材Ｍ２の表面を介して樹脂部材Ｍ１とガラス部材Ｍ２とが互いに押圧させられる。この状態で、ガラス部材Ｍ２に対する樹脂部材Ｍ１の対向面Ｓにおいて環状に延在する溶着予定領域Ｒに対して、各光ファイバＦ１〜Ｆ１３から所定の強度で略同時にレーザ光が出射される。出射されたレーザ光は、ガラス部材Ｍ２を透過して樹脂部材Ｍ１に吸収され、これにより、対向面Ｓにおいて樹脂部材Ｍ１が溶融し、溶融樹脂が膨張してガラス部材Ｍ２に押圧される。続いて、コントローラ５によってレーザ光の強度が徐々に低くされる。これにより、溶融樹脂が徐冷されて再固化するため、収縮応力が緩和されて、溶融樹脂が再固化する際にガラス部材Ｍ２との間に隙間が形成されることが防止される。そして、樹脂部材Ｍ１とガラス部材Ｍ２とが溶着されて樹脂・ガラス溶着体Ｐが製造される。   First, on the support base 2, the resin member M1 and the glass member M2 are pressed against each other through the surface of the glass member M2 modified by the silane coupling agent. In this state, laser light is emitted from the optical fibers F <b> 1 to F <b> 13 at a predetermined intensity substantially simultaneously to the planned welding region R extending in a ring shape on the facing surface S of the resin member M <b> 1 with respect to the glass member M <b> 2. The emitted laser light passes through the glass member M2 and is absorbed by the resin member M1, whereby the resin member M1 is melted on the facing surface S, and the molten resin expands and is pressed against the glass member M2. Subsequently, the intensity of the laser beam is gradually lowered by the controller 5. Thereby, since the molten resin is gradually cooled and re-solidified, the shrinkage stress is relaxed, and a gap is prevented from being formed between the glass member M2 and the molten resin when it re-solidifies. And the resin member M1 and the glass member M2 are welded, and the resin and glass welded body P are manufactured.

ここで、シランカップリング剤の反応について、３−アミノプロピルトリメトキシシランを例示して説明する。図４は、シランカップリング剤の反応を説明するための図である。   Here, the reaction of the silane coupling agent will be described by exemplifying 3-aminopropyltrimethoxysilane. FIG. 4 is a diagram for explaining the reaction of the silane coupling agent.

図４（ａ）に示される３−アミノプロピルトリメトキシシランによるガラス部材Ｍ２の表面処理は溶液中で実施される。そして、図４（ｂ）に示されるように、ガラス部材Ｍ２の表面の水酸基（−ＯＨ）にシランカップリング剤が水素結合によって接合される。その後、１００℃以上の温度で乾燥させられて脱水縮合反応が引き起こされることで、ガラス部材Ｍ２の表面にシランカップリング剤が固定化される。これにより、図４（ｃ）に示されるように、ガラス部材Ｍ２の表面に誘起された官能基の作用によって、溶融樹脂がガラス部材Ｍ２の表面に所定の分子間力で濡れることになる。   The surface treatment of the glass member M2 with 3-aminopropyltrimethoxysilane shown in FIG. 4A is performed in a solution. Then, as shown in FIG. 4B, the silane coupling agent is bonded to the hydroxyl group (—OH) on the surface of the glass member M2 by hydrogen bonding. Thereafter, the silane coupling agent is immobilized on the surface of the glass member M2 by being dried at a temperature of 100 ° C. or higher and causing a dehydration condensation reaction. Accordingly, as shown in FIG. 4C, the molten resin wets the surface of the glass member M2 with a predetermined intermolecular force by the action of the functional group induced on the surface of the glass member M2.

以上説明したように、樹脂・ガラス溶着装置１、及び樹脂・ガラス溶着装置１で実施される樹脂・ガラス溶着方法においては、シランカップリング剤によって改質されたガラス部材Ｍ２の表面を介して対向させられた樹脂部材Ｍ１とガラス部材Ｍ２との対向面Ｓにおいて樹脂部材Ｍ１が溶融するように、対向面Ｓおいて環状に延在する溶着予定領域Ｒに対して略同時にレーザ光が照射される。これにより、環状に延在する溶着予定領域Ｒにおいて樹脂部材Ｍ１が略同時に溶融して再固化するため、環状に延在する溶着予定領域Ｒの全体に渡って樹脂部材Ｍ１とガラス部材Ｍ２との溶着強度の低下を防止することができる。従って、樹脂部材Ｍ１とガラス部材Ｍ２との溶着の確実性が向上された樹脂・ガラス溶着体Ｐを製造することが可能となる。   As described above, in the resin / glass welding apparatus 1 and the resin / glass welding method carried out by the resin / glass welding apparatus 1, they face each other through the surface of the glass member M <b> 2 modified by the silane coupling agent. The laser beam is irradiated almost simultaneously on the planned welding region R extending annularly on the facing surface S so that the resin member M1 melts on the facing surface S between the resin member M1 and the glass member M2 that has been made. . Accordingly, since the resin member M1 is melted and re-solidified substantially simultaneously in the welding planned region R extending in an annular shape, the resin member M1 and the glass member M2 are formed over the entire welding planned region R extending in an annular shape. A decrease in welding strength can be prevented. Therefore, it becomes possible to manufacture the resin / glass welded body P in which the reliability of welding between the resin member M1 and the glass member M2 is improved.

また、レーザ光を照射するに際しては、レーザ光の強度が徐々に低くされる。そのため、溶融樹脂の急速な収縮を抑制することができ、樹脂部材Ｍ１とガラス部材Ｍ２との溶着の確実性をより一層向上させることが可能となる。   Further, when the laser beam is irradiated, the intensity of the laser beam is gradually lowered. Therefore, rapid shrinkage of the molten resin can be suppressed, and the certainty of welding between the resin member M1 and the glass member M2 can be further improved.

なお、溶融樹脂を徐冷するために、ヒータ等によって樹脂部材Ｍ１を加熱しておく手段も考えられるが、そのような手段には、次のような問題が存在する。すなわち、ヒータ等によって樹脂部材Ｍ１を加熱すると、溶着予定領域Ｒに沿った部分だけでなく、樹脂部材Ｍ１及びガラス部材Ｍ２の全体が加熱される。そのため、樹脂部材Ｍ１とガラス部材Ｍ２との線膨張係数の違いによって、ヒータ等による加熱の終了後に、樹脂部材Ｍ１が大きく収縮する。このとき、硬いガラス部材Ｍ２が樹脂部材Ｍ１の収縮を吸収することは極めて困難であるため、一旦溶着された樹脂部材Ｍ１とガラス部材Ｍ２とが比較的短時間で分離し易くなる。   In order to gradually cool the molten resin, means for heating the resin member M1 with a heater or the like is conceivable. However, such means have the following problems. That is, when the resin member M1 is heated by a heater or the like, not only the portion along the planned welding region R, but the entire resin member M1 and glass member M2 are heated. Therefore, the resin member M1 contracts greatly after completion of heating by a heater or the like due to the difference in linear expansion coefficient between the resin member M1 and the glass member M2. At this time, since it is extremely difficult for the hard glass member M2 to absorb the shrinkage of the resin member M1, the resin member M1 and the glass member M2 once welded are easily separated in a relatively short time.

また、樹脂部材Ｍ１とガラス部材Ｍ２とを対向させるに際しては、樹脂部材Ｍ１とガラス部材Ｍ２とが互いに押圧させられる。この場合、樹脂部材Ｍ１とガラス部材Ｍ２とが互いに押圧させられた状態で樹脂部材Ｍ１が溶融するため、樹脂部材Ｍ１とガラス部材Ｍ２との溶着強度をより一層高くすることができる。また、樹脂部材Ｍ１の反り等の変形が抑制されるため、樹脂部材Ｍ１とガラス部材Ｍ２とをより一層確実に溶着することができる。   Further, when the resin member M1 and the glass member M2 are opposed to each other, the resin member M1 and the glass member M2 are pressed against each other. In this case, since the resin member M1 is melted in a state where the resin member M1 and the glass member M2 are pressed against each other, the welding strength between the resin member M1 and the glass member M2 can be further increased. Further, since deformation such as warpage of the resin member M1 is suppressed, the resin member M1 and the glass member M2 can be more reliably welded.

本発明は、上述した実施形態に限定されるものではない。   The present invention is not limited to the embodiment described above.

例えば、上記実施形態では、環状の溶着予定領域Ｒが連続的に延在するものであったが、環状の溶着予定領域Ｒは、断続的に点在するものであってもよい。   For example, in the said embodiment, although the cyclic | annular welding plan area | region R extended continuously, the cyclic | annular welding plan area | region R may be scattered intermittently.

また、上記実施形態では、ガラス部材Ｍ２を透過したレーザ光を樹脂部材Ｍ１で吸収させることにより、接触面Ｓにおいて樹脂部材Ｍ１を溶融させる構成としたが、これに限定されない。例えば、樹脂部材Ｍ１もレーザ光を透過する場合には、樹脂部材Ｍ１の対向面Ｓに、レーザ光を吸収するレーザ光吸収部材を設けておき、ガラス部材Ｍ２を透過したレーザ光をレーザ光吸収部材で吸収させることにより、接触面Ｓにおいて樹脂部材Ｍ１を溶融させる構成としてもよい。レーザ光吸収部材としては、レーザ光を吸収する色素を含有するインク（対向面Ｓに塗布する）や、レーザ光を吸収する樹脂シート（対向面Ｓに配置する）等がある。   Moreover, in the said embodiment, although it was set as the structure which melts the resin member M1 in the contact surface S by making the resin member M1 absorb the laser beam which permeate | transmitted the glass member M2, it is not limited to this. For example, when the resin member M1 also transmits laser light, a laser light absorbing member that absorbs laser light is provided on the opposing surface S of the resin member M1, and the laser light that has transmitted through the glass member M2 is absorbed by the laser light. It is good also as a structure which melts the resin member M1 in the contact surface S by making it absorb with a member. Examples of the laser light absorbing member include ink containing a dye that absorbs laser light (applied to the facing surface S), a resin sheet that absorbs laser light (arranged on the facing surface S), and the like.
