Abstract

PURPOSE:To enable continuous welding of material more than 0.1mm. thick by connecting a driving horn squarely to the center of one surface of a rotating disc-shaped tool horn to arrange a disc-shaped pedestal rotating at the same circumferential velocity as the horn at the loop position point of the deflecting vibration thereof. CONSTITUTION:When integrating a disc 11 and a driving horn 3, a tool horn 4 rotates on the axis line of the driving horn 3 and apply longitudinal vibration to the driving horn, a circular deflecting vibration is generated in the disc 11. When a disc-shaped pedestal 12 turning at the same circumferential velocity as the tool horn is arranged as opposed thereto at the loop position point 14 of the vibration 13, the deflecting vibration can be utilized most efficiently. In addition, the width of the pedestal 12 can be 70-80% of the amplitude thereof and the proper selection of the diameter and thickness of the disc 11 and the service frequency enable the generation of a deflecting vibration of 2-8 order mode. Thus, a plurality of weldin lines can be formed continuously on a plastic sheet at a desired interval.

Drive horn 3 (
(also referred to as a fixed horn or a booster horn), a tool horn 4 that is connected to the drive horn 3 and is used to process the workpiece, a tip 5 provided at a portion of the tool horn 4 that comes into contact with the workpiece, and a tip 5. A case 6 is connected to a flange provided on the driving horn 3, surrounds a part of the vibrator 2 and the driving horn 3, and connects them to a pressurizing device. A plastic film 10 is sandwiched between the tip 5 and the pedestal 9, and ultrasonic vibrations are applied to the plastic film 10 through the tip 5 by the tool horn 4, and pressure is applied toward the pedestal 9. Meanwhile, the plastic film 10 is moved from the supply device 8 to the winding device 7 by the winding device 7, and a continuous weld line is formed on the plastic film 10. FIGS. 2(a) and 2(b) show the front and side views of the chip 5. When ultrasonic vibration is applied, the friction between the chip 5 and pedestal 9 and the plastic film IO is about +/+ 00, so the chip 5 and pedestal 9 are rotated in the form of rollers. The plastic film 10 can be smoothly moved even if the plastic film 10 is not moved. However, the thickness of the plastic film that can be welded by this device is 0. Thicknesses up to IM and thicker than this cannot be continuously welded.
