Abstract
In a vibration welding method and a vibration welding apparatus, a base plate and a vibrating plate which can be vibrated relatively to each other clamp an instrument panel, a storage box, and a duct as layers therebetween, which are joined to each other under pressure with vibration. A protective member of urethane is disposed on a workpiece rest for placing the base plate thereon. The storage box is made of a material having a relatively low melting point, and the duct is made of a material having a relatively high melting point. The thickness of the protective member is different depending on the location where the protective member supports the resin base, and the storage box or the duct.
Claims20
A vibration welding method for welding a resin base and resin workpieces to each other under pressure with vibration by clamping the resin base and the resin workpieces as layers between a first vibratory member and a second vibratory member, and then vibrating the first vibratory member and the second vibratory member relatively to each other, comprising the steps of:
- holding at least two of the resin workpieces in contact with the resin base;
- and
- providing a protective member between the resin base and the first vibratory member and/or between the resin workpieces and the second vibratory member,
- wherein a thickness of the protective member is different depending on the location where the protective member supports the resin base and/or the resin workpieces.
A vibration welding apparatus for welding a resin base and resin workpieces to each other under pressure with vibration, comprising:
- a first vibratory member and a second vibratory member for clamping the resin base and the resin workpieces as layers therebetween, while being vibrated relatively to each other, wherein at least two of the resin workpieces are held in contact with the resin base;
- and
- a protective member disposed between the resin base and the first vibratory member and/or between the resin workpieces and the second vibratory member, wherein a thickness of the protective member is different depending on the location where the protective member supports the resin base and/or the resin workpieces.
