What are the components of the control system of the ultrasonic welding machine?
The ultrasonic plastic welding machine consists of a pneumatic transmission system, a control system, an ultrasonic generator, a frequency converter, a cutter head and a mechanical device.
When working, the air compressor first drives the stroke cylinder to drive the ultrasonic transducer vibration system up and down. In low- and medium-power ultrasonic welding, the dynamic air pressure is adjusted according to welding needs.
The control system is composed of time relay or integrated circuit timer.
Its main function is to control the pneumatic transmission system to open the gas valve under timing control during welding, pressurize the cylinder, lower the welding head, and maintain a certain pressure on the welding object. After the welding is completed, the pressure is maintained for a period of time, and the control system reverses the gas valve to reset the welding joint; the second is to control the working time of the ultrasonic welding machine, so that the entire welding process is in operation, only by activating the button to generate a trigger Pulse, you can automatically complete the entire welding process. The sequence of the entire control system is: the power supply activates the pneumatic transmission system for triggering the control signal, the cylinder pressure welding head drops pressure welding, and the ultrasonic generator is triggered to emit ultrasonic waves and maintain a certain welding time, eliminate ultrasonic emission, and continue to maintain a certain pressure time , Decompression, the welding joint rises, and the welding ends.
The acoustic system of the ultrasonic plastic welding machine consists of three parts
1. Transmission part;
2. Fixed part;
3. Working parts. Among the above three components, the drive is the core, and the bolt-fixed longitudinal vibration sensor is generally used. The half-wavelength longitudinal vibrator is connected with the quarter-wave longitudinal vibrator, and the half-wave longitudinal vibrator is connected with the half-wave concentrator to form a full-wavelength plastic welding energy converter. The quarter-wave longitudinal vibrator and quarter-wavelength energy are concentrated The device is connected to form a half-wavelength plastic welding transducer wavelength sensor.
