Abstract

The invention discloses a servo pressure device for metal ultrasonic welding force regulation and control, and relates to the technical field of metal ultrasonic welding, wherein the servo pressure device comprises a servo pressure system and a welding force regulation and control system; the servo pressure system comprises a servo motor, a ball screw, a sliding block, an ultrasonic system clamp,a guide sleeve, a guide rail, a welding base and a welding machine frame. The guide sleeve is vertically fixed to the welding machine frame. The ball screw is vertically fixed at the output end of theservo motor; the guide rail is arranged in the guide sleeve in a sliding manner; the sliding block is fixedly arranged at the bottom end of the guide rail and driven by the ball screw, the ultrasonicsystem clamp is fixed to the sliding block, the welding base is fixed to the bottom of the welding machine frame, and the welding force regulation and control system integrates welding parameters andsensor signals and regulates the running state of the servo pressure system. Through the implementation of the servo pressure device, the real-time regulation and control and stable output of the welding force in the welding process can be realized.

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...
