Jacking ultrasonic welding machine

Abstract

The invention provides a jacking ultrasonic welding machine. The jacking ultrasonic welding machine comprises a welding machine support frame, wherein an energy converter rack is arranged on the welding machine support frame; an ultrasonic generator, an energy converter and a welding head are arranged on the energy converter rack; the energy converter rack is fixed on the welding machine support frame; a workbench is arranged below the welding head; the workbench is connected with a lifting mechanism; and the lifting mechanism is capable of driving the workbench to move up and down. The jacking ultrasonic welding machine differs from a common ultrasonic welding machine in that the energy converter rack is directly fixed on the welding machine support frame and does not move independently, and a jacking pressure is provided through the movement of the workbench below the energy converter rack, so as to realize workpiece welding. With the adoption of the manner, although the moving component is simply replaced only, the energy converter rack can be fixed, and therefore, the faults of resonance, howling and the like are avoided after adjustment during debugging only, and the jacking ultrasonic welding machine is more convenient to use.

Description

technical field [0001] The invention relates to an ultrasonic welding machine, in particular to a jack-up ultrasonic laser welding machine. Background technique [0002] Ultrasonic welding is a method that uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion method between molecular layers. The ultrasonic welding machine converts 50 / 60 Hz current into 15, 20, 30 or 40KHz electric energy through the ultrasonic generator during operation. The converted high-frequency electric energy is converted again into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through the horn device on the transducer. 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 thro...

AI Technical Summary

Problems solved by technology

There are certain problems in driving the ultrasonic frame through the cylinder. Because the ultrasonic welding machine will vibrate during operation, if the cylinder and the bracket of the ultrasonic transducer are not fixed well, the cylinder will drive the transducer frame to move. , the ultrasonic welding machine often whistles, so the connection between the cylinder and the ultrasonic transducer frame requires high requirements and the structure is relatively complicated, and it is necessary to adjust the connection between the bracket and the cylinder every time it works for a period of time. Prevent it from resonating, so it is not very convenient to use
