Abstract

The mechanical structure and control system of ultrasonic welding industrial robot were designed for the problem of low-precision of welding pressure. Firstly, the mechanical structure of the ultrasonic welding module was designed and the workspace of the robot was analyzed. Secondly, an ultrasonic welding industrial robot control system and a human-computer interaction system were designed. Finally, the welding verification experiment was carried out. The results show that the design of ultrasonic welding industry robot is reasonable and can quickly change the welding head. The workspace resembles a spherical shape and has better accessible in space with a radius of r < 1500 mm. The control system and the human-computer interaction system can work properly and reliably, the control precision of welding pressure can reach 1 N, the human-computer interaction system is clear and smooth, the maximum can meet the parameter setting of 30 welding points; The welding point quality of the door plate is better and the strength is higher. With high welding pressure control accuracy and high integration, the device has better suitable for most plastic ultrasonic welding scenarios.
