Ultrasonic welding machine

Abstract

The utility model belongs to the technical field of ultrasonic welding, and particularly relates to an ultrasonic welding machine which comprises a machine frame, a Z-axis driving mechanism, a lifting mechanism, an over-travel mechanism, a welding assembly and a cooling assembly, the Z-axis driving mechanism is installed on the machine frame, the lifting mechanism is arranged in the vertical direction of the machine frame, and the over-travel mechanism is installed on the machine frame. The Z-axis driving mechanism is in transmission connection with the lifting mechanism, an over-travel mechanism, a welding assembly and a cooling assembly are installed on the lifting mechanism, and the over-travel mechanism is in transmission connection with the welding assembly; the welding assembly comprises a welding head and a bottom die, the bottom die is used for supporting a workpiece, the welding head is arranged right opposite to the bottom die, and the cooling assembly is used for cooling the welding head; the Z-axis driving and over-travel mechanism layout is optimized, the welding precision and stability are improved, the welding head is cooled in the welding process by accurately controlling collaborative operation of the welding assembly and the cooling assembly, and the stability of the welding process is guaranteed.
