Ultrasonic welding treatment method and ultrasonic welding preheating assembly

Abstract

The invention provides an ultrasonic welding treatment method and an ultrasonic welding preheating assembly. The method comprises the steps that a hot-melting welding metal piece is placed on a welding platform, wherein a joint groove is formed in the hot-melting welding metal piece, and the joint groove is used for containing welding plastic; a welding plastic preheating piece is preheated, wherein the welding plastic preheating piece comprises a welding plastic plate and a plastic preheating wrapping and pressing bulge which are connected with each other, and the plastic preheating wrapping and pressing bulge corresponds to the joint groove; and the welding plastic preheating piece is placed on the hot-melting welding metal piece, and ultrasonic welding is carried out. The welding plastic preheating piece is preheated firstly, so that the internal energy of the welding plastic preheating piece is increased; a welding head transmits the internal energy to the plastic preheating wrapping and pressing bulge to reduce the internal energy required by hot melting of the plastic preheating wrapping and pressing bulge during ultrasonic welding, and the energy output of the welding plastic preheating piece is reduced, so that the energy consumption during ultrasonic welding is reduced, and therefore, the welding cost of ultrasonic welding is reduced.

Description

technical field [0001] The invention relates to the technical field of ultrasonic welding, in particular to an ultrasonic welding processing method and an ultrasonic welding preheating assembly. Background technique [0002] With the development of welding technology, welding of some non-metallic materials needs to be different from traditional welding technology, for example, ultrasonic welding technology, which converts 50 / 60 Hz current into 15, 20, 30 or 40KHz power. The converted high-frequency electric energy is converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction and melts the plastic. [0003] However, the traditional ultrasonic welding mach...

Problems solved by technology

[0003] However, when the traditional ultrasonic welding machine heat-melts plastic parts and metal parts, it takes a long time to weld, and the power consumption required for welding is relatively large, which leads to an increase in the energy consumption of the ultrasonic welding machine, which leads to the failure of the welded parts. Welding costs rise
