【発明の詳細な説明】
本発明は、表面処理部材を相手部材との間で好適に熱溶
着することができる表面処理部材の熱溶着方法に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for thermally welding a surface-treated member, which can suitably thermally weld a surface-treated member to a mating member.
従来、表面処理部材を相手部材との間で熱溶着するに際
しては、例えば第１図に示すように、塗装あるいは蒸着
等の表面処理を施した表面処理部材１を受は治具２で保
持させ、一方、表面処理を施しあるいは施していない相
手部材３も受は治具４で保持し、これらを対向させて熱
板５を用いて熱溶融したのち、前記熱板を取り除き、そ
れぞれの受は治具２，４を接近させて表面処理部材１と
相手部材３とを加熱溶着していた。Conventionally, when heat welding a surface-treated member to a mating member, for example, as shown in FIG. On the other hand, the mating member 3 with or without surface treatment is also held with a jig 4, and after these are placed facing each other and heated and melted using a hot plate 5, the hot plate is removed and each of the holders is The surface-treated member 1 and the mating member 3 were heat-welded by bringing the jigs 2 and 4 close to each other.
この場合、従来の表面処理部材１の熱溶着部６′は、第
２図に示すよらに、その溶着面が平坦な状態に形成され
ていた。In this case, the heat-welded portion 6' of the conventional surface-treated member 1 was formed so that its welded surface was flat, as shown in FIG.
したがって、熱溶着部６′を含む表面処理部材１の必要

本発明の目的は、前述した従来技術の欠点を解消し、熱
溶着部分における塗装膜あるいは蒸着膜などの表面処理
膜の残留をなくし、熱溶着部分での耐水性や溶着強度の
すぐれたものを得ることができる表面処理部材の熱溶着
方法を提案することにある。Therefore, if a necessary portion of the surface-treated member 1 including the heat-welded portion 6' has been surface-treated, after heat-welding is performed with the mating member 3, the surface-treated portion may be surface-treated within this heat-welded portion. The present invention has the disadvantage that the applied coating film, vapor deposited film, etc. remain, and the conformability between the surface-treated member 1 and the mating member 3 is reduced, making it impossible to satisfy the water resistance and welding strength after welding. The purpose of this is to eliminate the drawbacks of the prior art described above, eliminate the residual surface treatment film such as paint film or vapor deposited film on the heat welded part, and obtain excellent water resistance and welding strength in the heat welded part. The purpose of the present invention is to propose a method for thermally welding surface-treated members, which allows for the thermal welding of surface-treated members.
本発明の特徴とするところは、表面処理部材を相手部材
との間で熱溶着するにあたり、前記表面処理部材の熱溶
着部をあらかじめ断面先細の形状にしておき、前記断面
先細の熱溶着部を熱板に当ててその尖端部を流動除去し
た後、前記相手部材との間で加圧熱溶着を行なうように
した点にある。A feature of the present invention is that when thermally welding a surface-treated member to a mating member, the thermally welded portion of the surface-treated member is shaped in advance to have a tapered cross section; The point is that after the pointed end is fluidized by applying it to a hot plate, pressurized heat welding is performed with the mating member.
本発明の実施態様において、あらかじめ断面先細の形状
にする熱溶着部は、第３図に示すようなものとすること
ができる。In an embodiment of the present invention, the heat welded portion, which has a tapered cross section in advance, can be as shown in FIG.
すなわち、第３図ａに示す表面処理部材１の熱溶着部６
は、尖端が中央に位置する断面先細の形状をなし、第３
図すは尖端が部材の外側に、第３図Ｃは部材の内側にそ
れぞれ位置する断面先細の形状をなしている。That is, the heat welded portion 6 of the surface treated member 1 shown in FIG. 3a
has a tapered cross-section with the tip located in the center, and the third
The tip shown in the figure is located on the outside of the member, and the tip shown in FIG.
このように、表面処理部材１の熱溶着部６をあらかじめ
断面先細の形状にしておき、前記熱溶着部６を含めた必
要な部分に、塗装、蒸着その他の表面処理を施す。In this way, the thermally welded portion 6 of the surface-treated member 1 is made in advance to have a tapered cross-section, and necessary portions including the thermally welded portion 6 are subjected to painting, vapor deposition, or other surface treatment.
このようにした熱溶着部を有する表面処理部材の熱溶着
に際し、本発明においては、先づ熱溶着部に熱板を当て
てその尖端部を流動除去させる。When thermally welding a surface-treated member having such a thermally welded portion, in the present invention, a hot plate is first applied to the thermally welded portion to remove the tip portion by flowing.
すなわち、第４図ａに示す如く、熱溶着部６に熱板５を
用いて熱溶融を行なうと熱溶着部６の尖端部は第４図す
に示す如く両わき部分に流動し、さらに両者の間で加圧
すると、第４図Ｃに示す如く、流動部７がさらに大きく
なって押し出され、熱溶着部６はイ面が表われる。That is, as shown in FIG. 4a, when the heat welded part 6 is thermally melted using the hot plate 5, the tip of the heat welded part 6 flows to both sides as shown in FIG. When pressure is applied between them, as shown in FIG. 4C, the flowing portion 7 becomes larger and is pushed out, and the heat-welded portion 6 is exposed.
この際、表面処理膜部分は流動部７に押し流され、表面
処理膜の残留しないイ面が表われる。At this time, the surface treatment film portion is swept away by the flow section 7, and a surface where no surface treatment film remains is exposed.
したがって、その後相手部材との間で加圧熱溶着を行な
った場合でも、熱溶着部分に塗装膜や蒸着膜等の残留す
るおそれがなくなり、熱溶着部分での耐水性や溶着強度
の向上をはかることができる。Therefore, even if pressurized heat welding is subsequently performed with the mating part, there is no risk of paint or vapor deposits remaining on the heat welded part, improving the water resistance and welding strength of the heat welded part. be able to.
次に、第５図に基いて、本発明を自動車用灯具の製作に
実施した場合について説明する。Next, based on FIG. 5, a case will be described in which the present invention is applied to the production of an automobile lamp.
ここでは、表面処理部材として第５図ａに示すハウジン
グ１１を選定し、相手部材として第５図すに示すレンズ
１３を選定している。Here, the housing 11 shown in FIG. 5A is selected as the surface-treated member, and the lens 13 shown in FIG. 5S is selected as the mating member.
このとき、本発明に従ってハウジング１１の熱溶着部１
６は断面先細の形状になされている。At this time, according to the present invention, the heat welded portion 1 of the housing 11 is
6 has a tapered cross section.
そして、熱板等を用いて熱溶着部分を熱溶融させ、熱溶
着部１６の表面処理膜を両わき部分に流動させたのち、
第５図Ｃに示す如く、ハウジング１１とレンズ１３とを
熱溶着固定する。Then, the heat-welded part is melted using a hot plate or the like, and the surface treatment film of the heat-welded part 16 is flowed to both side parts.
As shown in FIG. 5C, the housing 11 and the lens 13 are fixed by heat welding.
このようにして、前面先細の形状にした本発明法による
ものと、断面平坦な形状の従来法によるものとを比較し
たところ、次表に示す結果を得た。In this way, the results shown in the following table were obtained by comparing the results obtained by the present invention method with a tapered front surface and the conventional method with a flat cross-sectional shape.
上表から明らかなように、本発明法では溶着部分に塗装
膜や蒸着膜等が残留しないため、従来法に比較して剥離
強度および気密性のいずれにおいてもすぐれている。As is clear from the above table, the method of the present invention does not leave any paint film, vapor deposited film, etc. on the welded area, and therefore is superior to the conventional method in terms of both peel strength and airtightness.
以上詳述したところから明らかなように、本発明によれ
