Bonding method for a plurality of components, bonding method for container and lid member, and ultrasonic welding apparatus

Abstract

According to a bonding method of heat-welding a plurality of components in a predetermined lengthwise direction by vibration of an ultrasonic vibrator, the plurality of components are fixed such that their bonding positions are aligned, the ultrasonic vibrator is oscillated, and the plurality of components and ultrasonic vibrator are moved relative to each other in the lengthwise direction, thus performing heat welding.

1 . A bonding method for a plurality of components, of heat-welding the plurality of components in a predetermined lengthwise direction by vibration of an ultrasonic vibrator, wherein the plurality of components are fixed such that bonding positions thereof are aligned, said ultrasonic vibrator is oscillated, and the plurality of components and said ultrasonic vibrator are moved relative to each other in the lengthwise direction, thus performing heat welding.  
   
   
       2 - 4 . (canceled)  
   
   
       5 . A bonding method for a container and lid member, of closing an opening of the container with the lid member, wherein the lid member is placed over the opening of the container, an ultrasonic vibrator is brought into contact with the lid member and is oscillated in order to bond a periphery of the opening, and the container or said ultrasonic vibrator is moved relative to the periphery of the opening, thus performing heat welding.

       7 . (canceled)  
   
   
       8 . A bonding method for a container and lid member, of closing an opening of the container with the lid member, wherein when the lid member is to be placed over the opening of the container, said ultrasonic vibrator is to be brought into contact with the lid member and is to be oscillated in order to bond a periphery of the opening, and the container or said ultrasonic vibrator is to be moved relative to the periphery of the opening when performing heat welding, a relative moving speed in the vicinity of a bonding end position of the opening is decreased.  
   
   
       9 - 11 . (canceled)  
   
   
       12 . An ultrasonic welding method of ultrasonic-welding a plurality of components over a predetermined length, wherein when the components softened by heating are to be welded to an opposite side by pressing the plurality of components within a range of the length, pressing at a contact position of an ultrasonic vibrator is avoided, and a welding portion is pressed after the ultrasonic vibrator moves.
