Control System: Control system It consists of a time relay or a timer for integrated circuit time. Its main function is: one is the system operation of the controlled pneumatic transmission, so that when it is welded, the valve of the gas path is opened under the timing control, and the pressure of the cylinder causes the welding head to descend, so that a certain pressure is pressed against the object to be welded. When the welding is completed, the pressure is kept for a period of time, and then the control system reverses the valve of the gas path, so that the welding head is raised to the reset; the second is the working time of the generator for controlling the ultrasonic wave, and the system realizes the automation of the entire welding process. At the time of operation, only the start button is needed to generate a trigger pulse, so that it can be automatically completed in the whole process of the welding. The sequence of the entire control system is: power-on-trigger-trigger control signal, pneumatic transmission system, the head of the cylinder pressure welding is lowered and the welding triggers the operation of the ultrasonic generator, the ultrasonic wave is emitted and a certain welding time is maintained, and the removal is performed. Ultrasonic emission and continued to maintain a certain pressure time to depressurize, the welding head is raised and the welding is finished.
