Description
technical field [0001] The invention relates to the technical field of metal ultrasonic welding, in particular to a servo pressure device for regulating the force of metal ultrasonic welding. Background technique [0002] At present, metal ultrasonic welding machines on the market all use cylinders to provide welding pressure. However, due to the obvious plastic deformation and softening of the metal material during the welding process, the reaction force on the welding head is constantly changing, making the cylinder unable to maintain a stable welding pressure, resulting in poor welding quality; and the current metal The ultrasonic welding method adopts constant welding parameters. During the welding process, the welding head pressure, amplitude and other parameters keep the set values unchanged, and the adjustment of the welding pressure and the precise control of the welding head displacement cannot be realized during the welding process, resulting in ultrasonic weldin...
