The present invention relates to a joining method suitably employed for joining.

固な接合強度が得られる。Conventional technology and its problems Conventionally, for example, in joining components of a picture frame made of hard synthetic resin, the surfaces of the components to be joined are first heated and melted using a heater or the like.
A method has been adopted in which these bonding surfaces are immediately butted together and fused and fixed. In such a method, the two members are compatible with each other and a strong joint strength can be obtained.

しかしながら、接合箇所の周囲に所謂バリが発

らず、加工精度が悪いという難を有していた。 However, so-called burrs tend to occur around the joints, which impairs the appearance of the joint, requiring a troublesome finishing process to remove the burrs, and also has the disadvantage of poor processing accuracy.

つた。 Still other methods include high-frequency welding, which utilizes heat generated by molecular motion in a high-frequency electric field, ultrasonic welding, which utilizes frictional heat generated by ultrasonic vibration, and even welding that uses heat sprayed from a hot air welding machine. Various welding methods such as hot air welding, which involves melting using a hot air stream such as heated air, are sometimes used, but all of these methods require large or special equipment, which is difficult to do at construction sites, for example. The problem was that it could not be adopted.

ある。 On the other hand, instead of the above-mentioned joining methods, methods of joining using adhesives have been widely adopted, but compared to the above-mentioned joining methods, sufficient joining strength cannot be obtained, or the material of the joining members In some cases, the problem is that suitable adhesives do not exist.

Furthermore, the present invention attempts to present a method for joining joining members that can be constructed on-site without requiring any special equipment or the like.

のである。Means for Solving the Problems For the above purpose, the inventor has conducted various experiments and researches, and found that by applying electricity to a conductive thermoplastic synthetic resin film, it generates Joule heat, and this heat causes They focused on the fact that the film melts and that the melted synthetic resin has an adhesive effect, leading to the completion of this invention.

It is not limited. It may also be made of other materials such as wood or metal,
Furthermore, the present invention is not limited to a combination of the same type of joining members, but may be any combination of different types of joining members.

Examples include butadiene-styrene synthetic resin (ABS), polystyrene synthetic resin (PS), polycarbonate synthetic resin (PC), and the like.

要である。 On the other hand, the film used to join these joining members is a thermoplastic synthetic resin film having conductivity, and when electricity is applied to it, Joule heat is generated, and the film itself is damaged by the heat. It needs to be something that can be melted.

電性を有するものであつてもよい。 Examples of such films include polyvinyl chloride synthetic resin (PVC), acrylonitrile-butadiene-styrene synthetic resin (ABS), polystyrene synthetic resin (PS), and polycarbonate synthetic resin (PC).
A thin nichrome wire can be used which is formed by embedding a thin nichrome wire over almost the entire surface of the base film. However, instead of this nichrome wire, a patterned heater wire circuit may be provided within the base film as described above, for example. Furthermore, conductive materials such as carbon (C), tin oxide (SnO 2 ), silver (Ag), copper (Cu), etc. are kneaded into the above-mentioned plastic-phobic synthetic resin film. It may be.

この導電性合成樹脂フイルムは、接合部材が熱
可塑性合成樹脂材である場合には、同種類の相溶
性を有するものを用いることが接合容易性あるい
は接合強度向上の観点から望ましい。 When the bonding member is a thermoplastic synthetic resin material, it is desirable to use a conductive synthetic resin film having the same type of compatibility from the viewpoint of ease of bonding or improvement of bonding strength.

また、そのフイルムの厚さは、加工精度を向上
するためには可及的薄いものであることが必要で
あるが、接合部材の用途に応じた接合強度を得る
ためには必要最低限の厚さとすることが必要であ
ることは言うまでもない。通常、厚さ0.3〜0.7mm
程度、好ましくは0.5mm以下のものが用いられる。 In addition, the thickness of the film must be as thin as possible in order to improve processing accuracy, but it must be as thin as possible to obtain the bonding strength appropriate for the application of the bonded member. It goes without saying that it is necessary to take this into account. Usually thickness 0.3~0.7mm
A diameter of 0.5 mm or less is used.

上記フイルムへの通電は、例れば該フイルムが
塩化ビニル合成樹脂をベースとするものであれ

熱させれば良い。要するに、前記フイルムがこれ
に発生ジユール熱により溶融しうる条件を満たす
ものであれば、電源の種類が直流であるか交流で
あるかを問わず、又印加電圧や通電時間等も限定
されるものではない。 For example, if the film is based on vinyl chloride synthetic resin, the film may be heated to about 150 to 200°C, which is the melting point of the film. In short, as long as the film satisfies the conditions that it can be melted by the Joule heat generated, it does not matter whether the type of power source is DC or AC, and there are also limitations on the applied voltage, energizing time, etc. isn't it.

ところで、接合部材が熱可塑性合成樹脂材どお
しである場合には、その接合部が前記フイルムと
共に溶融して一体的に接合されることとなるもの
である。一方、接合部材が上記以外のものである
場合には、溶融されたフイルムの樹脂が接着剤と
して作用することになる。 By the way, when the bonding member is made of thermoplastic synthetic resin materials, the bonded portion is melted together with the film and is integrally bonded. On the other hand, if the bonding member is other than those mentioned above, the resin of the melted film will act as an adhesive.

また、前記接合部材を仮固定するに際しては、
所定の圧力を加えることが望ましいことは言うま
でもない。 In addition, when temporarily fixing the joining member,
It goes without saying that it is desirable to apply a predetermined pressure.

また、前記フイルムは、接合部材の接合面に対
応した大きさのものを使用するのが一般的である
が、場合によつてはこれよりも大きいものや小さ
いものを使用しても良い。大きいものを使用した
場合でも、該フイルムが薄いものであるから周囲
のはみ出し部分を取除く仕上げ作業も容易であ
る。なお、小さいものを使用する場合には電極端
子を外部に導いておく必要がある。 Further, although it is common to use a film of a size corresponding to the joint surface of the joining member, a film larger or smaller than this may be used depending on the case. Even if a large film is used, since the film is thin, the finishing work of removing the protruding portions around the periphery is easy. In addition, when using a small one, it is necessary to lead the electrode terminal to the outside.

しうる。Effects of the Invention When the joining members are made of thermoplastic synthetic resin, the resistance heating joining method of various joining members according to the present invention has no effect on joining strength compared to the conventional fusion fixing method. Not only is it comparable, so-called burrs are less likely to occur around the joint, and finishing processing can be made unnecessary or easy. Also,
It is possible to bond even synthetic resin materials for which no suitable adhesive exists, such as fluorocarbon resin materials.

関係に採用しうる。 Furthermore, since joining can be performed as long as there is a power source, there is no need for large or special equipment such as those used in high-frequency welding methods, and it is not only possible to carry out on-site work, but also to make it possible to perform the joining on-site. It can be adopted almost independently.

ルムの電極間抵抗値は略200Ωであつた。 The synthetic resin film 2 used to join these members 1 and 1 is a base film 3 made of vinyl chloride synthetic resin with a thickness of 0.5 mm and a size of 10 mm x 50 mm. A nichrome wire 4 with a thickness of 60 μm is placed 1 mm in the base film 3.
In addition to arranging them in parallel at intervals, we adopted a method in which they were buried in a parallel-connected state. The interelectrode resistance value of this film was approximately 200Ω.
