。Traditionally, two resin parts have been joined by various welding methods such as friction welding, high-frequency welding, ultrasonic welding, and hot air welding, but how can the joint surfaces between these two parts be brought into close contact? A major challenge was how to increase the bonding strength between them. In particular, when these two resin parts are made of different materials, the physical properties (melting point, polarity, etc.) of the two parts are necessarily different, so it is impossible to weld and bond their joint surfaces at the same time. It was necessary to take some kind of measure for bonding.

た組付工数も多くなり、複雑となる問題があった。However, none of the various joining methods that have been proposed to date are yet satisfactory, especially when it comes to joining dissimilar materials. Since a joining structure using a third part or the like is adopted, there are problems in that the number of parts is large, the number of assembly steps is also increased, and the process becomes complicated.
ここにおいて、本発明は、所定の溶着操作によって二つ

介在させることなく直接に行ない得るようにした手法を
提供することにある。An object of the present invention is to provide a joining method that can effectively increase the joining strength between two resin parts by a predetermined welding operation, and particularly between parts made of different materials. It is an object of the present invention to provide a method that allows the joining of the parts to be performed directly without intervening a third component.

うにしたことを特徴とする樹脂部品の接合方法にある。Therefore, when joining, a groove extending in the joining direction is provided on the joint surface of one resin part, and a plurality of protrusions that can enter the groove and have their tips abut against the bottom of the groove are formed on the other resin part. By providing the groove in the extending direction of the joint surface of the component and performing a predetermined welding operation, the tips of adjacent protrusions provided on the other resin component can be brought closer together or are brought into contact and fused together, and at the same time, the melted/softened material produced by the melting or softening of the joint surfaces of the resin part is allowed to enter into the base space between the adjacent holes. It's in the joining method.

接合強度が達成されることとなるのである。Therefore, according to the method of the present invention, a plurality of protrusions provided on the bonding surface of one resin component enter into the groove provided on the bonding surface of the other resin component, and the tips of the protrusions are welded. By being melted by the operation, the tips of the adjacent protrusions are brought close to each other, brought into contact, and welded, and furthermore, the resin parts of one or both of the above-mentioned parts are formed in the base space of the adjacent protrusions. An effective anchoring effect can be found by allowing the molten or softened material to penetrate and solidify. As a result, high bonding strength can be achieved.
以下、図面を参照しつつ、本発明について更に詳細に説
明することとする。Hereinafter, the present invention will be explained in more detail with reference to the drawings.
先ず、第１図において、１０は樹脂部品の射出成形など

長手形状をなし、その下面には長手方向に一定の幅と長
さと高さを有する複数（本実施例では３＠）の突部１２
が設けられている。First, in FIG. 1, numeral 10 is a first member formed by injection molding of resin parts, etc. The second member 10 has a longitudinal shape, and has a constant width in the longitudinal direction on its lower surface. A plurality of (3@ in this example) protrusions 12 having a length and a height of
is provided.
そして、第２図に示される第二の部材１４は、前記第一
部材１０の接合の対象とされる樹脂部品であり、該第一
部材１０と同様に射出成形などにて形成されて−いる。The second member 14 shown in FIG. 2 is a resin part to which the first member 10 is joined, and is formed by injection molding or the like similarly to the first member 10. .
該第二部材１４は長手形状をなし、その上面には長手方
向に一定の幅と長さと深さを有する溝１６が設けられて
いる。そして、該溝１６内に、第一部材１０の突部１２

すると共に、該突部１２と該溝１６の内側面との間及び
溝１６の両端部内側面と該突部１２との間には一定の隙
間を有するように該溝１６が形成される。The second member 14 has a longitudinal shape, and a groove 16 having a constant width, length, and depth in the longitudinal direction is provided on its upper surface. Then, the protrusion 12 of the first member 10 is inserted into the groove 16.
is inserted and its tip is brought into contact with the bottom of the groove 16, there is a slight gap between the upper surface 15 of the second member 14 and the lower surface 13 of the first member 10 on both sides of the protrusion 12. The groove 16 is formed so as to have a certain gap between the protrusion 12 and the inner surface of the groove 16 and between the inner surface of both ends of the groove 16 and the protrusion 12. Ru.
従って、それら両部材の接合に際しては、第３図（ａ）

第一部材１０の下面１３が当接させられるようになる。Therefore, when joining these two members, as shown in Fig. 3(a),
After inserting the protrusion 12 of the first member 10 into the groove 16 of the second member 14 having such a configuration as shown in FIG. A welding operation is applied, such as reciprocating friction welding, in which both members 10.14 are reciprocated in the longitudinal direction while pressing the surfaces 18 together with a predetermined pressure. Then, the frictional heat generated by this operation heats the abutting surfaces of the tips of the plurality of protrusions 12, that is, the joint surfaces 18, so that the tips and the groove bottoms are first melted or softened. h. Due to the pressing force applied to the first member IO, the melted material or softened material is forced to spread to the bottom side of the groove 16, and the protrusion 12 is pushed down. , the upper surface 15 of the second member 14 and the lower surface 13 of the first member 10 on both sides of the protrusion 12 come into contact with each other.

is melted or softened by the frictional heat generated by the welding operation, producing a molten or softened material 22. Furthermore, when the protrusion 12 is reciprocated within the groove 16, the molten material or softened material at the tip of the protrusion 12 and the bottom of the groove is pushed and spread toward the space side with less resistance, and Their tips are brought close to each other, or brought into contact or fused together. The melted material or softened material 22 generated on the joint surface 20 is moved into the base space 24 of the adjacent protrusion 12 by the action of the pressing force applied to the joint surface 20 and further by their sliding action. At the same time, the molten material or softened material is forced to spread toward the space at both upper edges of the groove 160. FIG. 3(b) shows this state. In this state, when the molten material or softened material 22 is cooled and assimilated, an anchor effect occurs, and both members 10,
This is because strong bonding strength can be obtained between the 14 points.

こ−とと逐るのである。If the welding operation progresses further than the state shown in FIG. 3(b), the tips of the adjacent protrusions 12 will come into contact and be fused together, and the base space 24 and surrounding spaces will also be affected. As the molten material or softened material 22 is further filled, a greater anchoring effect is produced due to its cooling and solidification, and both members 10 and 14 are joined with even stronger bonding strength. That's what I'm saying.
第３図（ｃ）はこの接合状態を示すものである。FIG. 3(c) shows this bonded state.

きるのである。Therefore, such a joining method has the great advantage that resin parts made of different materials can be directly joined. That is, unlike the conventional bonding method using melt adhesion, which is a combination of flat surfaces, one resin component (14) has a groove (16) in the other resin component (10).
) by inserting the protrusions (12) and applying a welding operation, the tips of the plurality of adjacent protrusions (12) are brought closer together or brought into contact and fused, and the protrusions (12) Base space (
24) is filled with the melted or softened material (22) of one member (14) and then cooled and solidified to produce a large anchor effect.
Even if there is no welding action on the joint surfaces, the two can be reliably joined, and the two can be directly joined with great joint strength without using a third part of the oil spray.

そのような場合をも含むものである。The improvement in bonding strength due to such an anchor effect is not only effective for bonding resin parts made of different materials as described above, but also extremely effective for bonding resin parts made of the same type of material. However, when joining resin parts made of the same type of material, in addition to melt adhesion between the two at their joining surfaces, it is also necessary to simply weld the joining surfaces to improve the bonding strength between the two based on the anchor effect described above. In comparison, it exhibits even more excellent bonding strength. Therefore, the present invention is suitably applied not only to joining two parts made of different types of thermoplastic resins, but also to joining parts made of the same type of thermoplastic resin, and the present invention includes such cases. It is something that

One end or both ends may be grounded and the other both ends may be open, and the shape of the groove provided on one resin part and the protrusion provided on the other resin part to be inserted into this, The size, number, etc. will be appropriately determined depending on the desired anchor effect, in other words, the degree of bonding strength between the two parts. Furthermore, if the resin parts can rotate on their joining surfaces, by making the grooves and protrusions annular, a rotary friction welding operation can be adopted in addition to the exemplified reciprocating friction welding method, and furthermore, other It is also possible to employ known welding operations such as ultrasonic welding, high frequency welding, and hot air welding.
