Abstract

PURPOSE:To attempt to shorten welding time and to simplify a controlling movement of an ultrasonic horn by injecting an apex part of the ultrasonic horn into a resin component of one of different materials and moving it in the direction perpendicular to the direction of injection to form a gap. CONSTITUTION:Resin components 2 and 3 of different materials are laminated and an ultrasonic horn 1 is brought into contact with a resin component 2 and the contacted part is heated and melted by means of an ultrasonic vibration and the horn is reciprocally moved in the perpendicular direction to the direction of injection while it is injected into the resin component 2 to a distance of the thickness of the resin component 2 and the melted part 21 is pushed out to the surface and thereby built up on the surrounding. In this instance, a gap 2A is formed between the ultrasonic horn 1 and the resin component 2. Then, the vibration of the ultrasonic horn 1 is stopped and the ultrasonic horn is furthermore injected into a specified amount while the resin parts of lower side is heated and melted by means of the ultrasonic horn 1. A melted part 31 is thereby pushed out through the gap 2A between the resin component 2 and the ultrasonic horn 1 and covers over the melted part 21 of the resin component 2. Both resin components 2 and 3 are thereby strongly jointed together.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、異種材料樹脂部品を重ね合わせ超音波により
溶かして溶着させる異種材料樹脂部品の超音波溶着方法
に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for ultrasonic welding of resin parts made of different materials, in which resin parts made of different materials are superimposed and melted and welded using ultrasonic waves.

〔従来の技術〕[Conventional technology]

従来、異種材料樹脂部品の接合方法としては、接着剤を
用いた化学的接合方法、ネジを用いた機械的接合方法、
あるいは、熱を加えて溶着する物理的接合方法が広く利
用されている。Conventionally, methods for joining resin parts made of different materials include chemical joining methods using adhesives, mechanical joining methods using screws,
Alternatively, physical joining methods that involve welding by applying heat are widely used.

この方法は、同種の樹脂部品を接合するには適している
が、異種の樹脂部品を接合する際には、樹脂部品の材質
によっては接着剤の接着力が低下し、両樹脂部品を強固
に接着することが困難である。Among these, chemical bonding methods using adhesives involve interposing an adhesive such as hot melt on the joint surfaces of the resin parts to be joined, and applying high frequency or ultrasonic waves from the surface of one resin part to apply the adhesive. After heating and melting, both resin parts are cooled while applying pressure to join them.
This method is suitable for joining resin parts of the same type, but when joining resin parts of different types, the adhesive force of the adhesive may decrease depending on the material of the resin parts, and it may be difficult to bond both resin parts firmly. Difficult to glue.

二番目のネジを用いた機械的接合方法は、両樹脂部品の
接合部位に貫通孔を形成しておき、一方の樹脂部品より

ネジを螺合する作業が必要となり、接合作業が煩雑とな
る欠点がある。また、両樹脂部品に貫通孔が形成されて
いるので、強度が低下する不具合がある。The second mechanical joining method using screws is to form a through hole in the joining area of both resin parts, insert a screw from one resin part and screw it into the other resin part, and then connect both resin parts. Although this method is suitable for joining different types of resin parts, it requires the work of forming through holes in both resin parts and screwing together screws, making the joining work complicated. Furthermore, since the through holes are formed in both resin parts, there is a problem that the strength is reduced.

最後の熱による物理的接合方法は、樹脂部品に超音波や
振動を加えて樹脂部品を熔かして接合するものであり、
接合すべき樹脂部品以外のものが接合部に介在しないの
で異種材料の樹脂部品の接合方法として適している。The final method of physical bonding using heat is to melt and bond resin parts by applying ultrasonic waves or vibrations to the resin parts.
Since nothing other than the resin parts to be joined is present at the joint, this method is suitable as a method for joining resin parts made of different materials.

この物理的接合方法の一つである超音波溶着方法の従来
例を、第５図および第６図に示す。A conventional example of an ultrasonic welding method, which is one of these physical joining methods, is shown in FIGS. 5 and 6.

この超音波溶着方法においては、溶着工程の前工程にて
、予め、一方の樹脂部品５１に貫通孔５２を開けておき
、他方の樹脂部品５３に前記貫通孔５２に入るだけのボ
ス５４を立てておく。そして、両樹脂部品５１．５３を
、第５図のように重ね合わせ、次いで、第６図のように
ボス５４に超音波を当てて溶融し、アンカー効果により
接合する。In this ultrasonic welding method, a through hole 52 is drilled in advance in one of the resin parts 51 in a pre-process of the welding process, and a boss 54 just enough to fit into the through hole 52 is erected in the other resin part 53. I'll keep it. Then, both resin parts 51 and 53 are overlapped as shown in FIG. 5, and then, as shown in FIG. 6, the bosses 54 are fused by applying ultrasonic waves and are joined by an anchor effect.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

しかし、前記したような従来の超音波溶着方法では、溶
着工程の前工程で一方の樹脂部品５１に孔明及び他方の
樹脂部品５３にボス立での作業が必要であり、生産性が
低く加工コストが高くなる欠点がある。However, in the conventional ultrasonic welding method as described above, it is necessary to drill holes in one resin part 51 and to stand a boss in the other resin part 53 in the pre-welding process, resulting in low productivity and high processing costs. It has the disadvantage of being high.

また、大物部品においては、一方の樹脂部品５１の貫通
孔５２と他方の樹脂部品５３のボス５４との間の芯ズレ
が生じ易く、この芯ズレが生じると接合できなくなり、
そのため、芯ズレの生じ難い小物部品でしかこの超音波
溶着は行われていなかった。In addition, in large parts, misalignment between the through hole 52 of one resin component 51 and the boss 54 of the other resin component 53 is likely to occur, and when this misalignment occurs, it becomes impossible to join.
For this reason, ultrasonic welding has only been used for small parts that are unlikely to be misaligned.

なお、芯ズレを吸収するために貫通孔５２の内径を大き
くすると、ボス５４の溶融量不足により両者の間が完全
に埋まらず強度不足となるので、強度を必要とされる大
物部品には採用されていなかった。Note that if the inner diameter of the through hole 52 is increased to absorb misalignment, the space between the two will not be completely filled due to insufficient melting amount of the boss 54, resulting in insufficient strength, so this method is not used for large parts that require strength. It had not been done.

特願昭６３−３７１８７号）。Therefore, the present applicant created a hole in one resin part using an ultrasonic horn for welding, and then used the ultrasonic horn to melt the other resin part and cover it with the other resin part to join the different parts. We proposed an ultrasonic welding method for material resin parts (

るようにしている（第１１図）。In this method, as shown in FIGS. 7 to 11, resin parts 61 and 62 made of different materials are overlapped to form an ultrasonic horn 64 having a tapered plate part 63 at its tip. is placed in contact with one of the resin parts 61 and heated and melted by applying ultrasonic waves to press fit the thickness of the one resin part 61 (Figs. 7 and 8). In this state, the ultrasonic horn is 64 is rotated to extrude the molten portion 65 of the one resin component 61 to the surface thereof, causing it to bulge around the formed recess (FIGS. 7 and 8), and then the other resin component 62 is heated and heated. It is melted and further press-fitted into the other resin part 62 to a predetermined depth and rotated in the reverse direction (Fig. 9, 1).
0), the molten part 67 of the other resin part 62 is extruded to cover the molten part 65 of the one resin part 61 (Fig. 11).

この方法は、一連の溶着工程の中で樹脂部品６■に孔を
開けることができるため、前工程での穿孔などの加工が
不要となり、又、芯ズレなどの問題も起こらない。In this method, holes can be made in the resin part 6 during a series of welding processes, so processing such as drilling in the previous process is not necessary, and problems such as misalignment do not occur.

しかし、この方法では、超音波ホーン６４の回動角度制
御が必要となり、その分、溶着装置のコストが高くなる
とともに溶着時間も長くなる欠点がある。However, this method requires control of the rotation angle of the ultrasonic horn 64, which has the drawback of increasing the cost of the welding device and lengthening the welding time.

。Therefore, the present invention eliminates the need for the rotation angle movement of the ultrasonic horn and its control in ultrasonic welding of resin parts made of different materials, in which drilling and welding operations are simultaneously performed using an ultrasonic horn. The purpose is to shorten the welding time and simplify the control operation of the ultrasonic horn.

Specifically, a gap is formed between the horn and the resin part. Specifically, resin parts made of different materials are stacked one on top of the other, and the ultrasonic horn having a circular cross-sectional shape is attached to one of the resin parts. The ultrasonic horn is heated and melted by applying ultrasonic waves while being pressed, and the molten portion is pushed out to the surface of the recess by approximately the same thickness, causing a bulge around the formed recess. A predetermined gap is formed between the two resin parts by moving the resin part in a perpendicular direction, and then the other resin part is heated and melted, and an ultrasonic horn is further press-fitted to a predetermined depth to separate the other resin part. The molten part of the resin part is extruded to cover and join the molten part of the one resin part.
