し、軟化して溶着することになる。"Operation" When the ultrasonic vibrator is excited, strong ultrasonic vibrations are generated at the pressing part at the end of the vibrating horn. If the overlapping part of the synthetic resin (the part to be welded) is held under pressure between the pressing part and the pressure receiving member, the overlapping part of the synthetic resin will generate frictional heat due to the ultrasonic vibration from the pressing part, and will soften. It will be welded.

I can do it. Reference numeral 2 denotes a box-shaped upper member disposed above the lower member 1. Both side plates 2a, 2a at one end of the upper member 2 are loosely fitted to a shaft 3, and are pivotable via a spring 4 wound around the shaft 3. is connected to. These lower member 1 and upper member 2 form a grip body G. Reference numeral 5 indicates an ultrasonic transducer attached to a through hole S formed in the lower plate 2b at the other end of the grip main body G, that is, the other end of the upper member 2, and as shown in detail in FIG. Part 5a

によつて確実に溶着することが認められた。 Now, the body 5a is 11mmφ×6mmt, and the body 5a is 12mmφ×
0.5mmt flange 5b and 8mmφ×3mmφ×8
mm exponential type vibration horn 5c,
There is a 0.2 mmt gap between the end surface (pressing surface 5f) of the vibration horn of the ultrasonic vibrator 5, which has a piezoelectric element 5d of 10 mmφ×1 mmt and is set at a resonance frequency of 100 KHz, and the pressure receiving member 8 made of a metal plate. A stack of two vinyl sheets is pressed and held as an object to be welded, and a high frequency voltage with an input power of 3 W is applied to the vibrator 5 for 2 seconds.The part that contacts the pressing surface 5f and the pressure receiving member 8 is Ultrasonic vibrations caused frictional heat generation and welding, and even when the welded parts were pulled by hand, they did not peel off, but rather broke from the periphery of the welded parts, and it was confirmed that ultrasonic vibrations could reliably weld.

行なうことができる。 As shown in FIG. 3, one or both of the facing surfaces of the pressing part 5f of the ultrasonic transducer and the pressure receiving member may be rough surfaces 5f', 8a, or as shown in FIG. By forming a concave portion 5f'' on the opposing surface of the and pressure receiving member, one of which is on the pressing part 5f side, and a convex portion 8b that penetrates into the concave portion 5f'' on the other side, here, on the pressure receiving member side. Welding can be performed more reliably by promoting the frictional heat generation effect due to sonic vibration.
