Research On Ultrasonic Efficient Cleaning Electronic Connector

In recent years,with the rapid development of power electronics manufacturing technology,electronic connectors play an important role in power electronic devices.In the manufacturing process of electronic connectors will be attached to some dirt.In order to improve the quality of products,it is very important to choose an effective cleaning method before assembly.Ultrasonic cleaning is an efficient and intelligent cleaning method.In the industrial cleaning occupies an important position,ultrasonic cleaning technology is widely used at the same time,its performance improvement is inevitable.In this paper,according to the development of ultrasonic cleaning technology at home and abroad,this paper puts forward the main points of the design.The main factors affecting ultrasonic cleaning are analyzed and compared,and the optimum condition of the electronic connector is found.The impedance characteristics of the transducer is analyzed,and the impedance matching circuit is designed to improve the power factor of the circuit.In this paper,in order to clean the sound field in the ultrasonic wave,the lateral connection of transducer is designed.This paper puts forward a scheme to improve the cleaning efficiency by heating the cleaning solution.The power supply system is controlled by Freescale's MC9S12XS128 Carle single chip microcomputer as the main control device.In order to improve the work efficiency of the ultrasonic power supply,this paper designs an automatic frequency tracking scheme.Finally,the output of ultrasonic excitation power supply is tested and analyzed.Test waveform is good,meet the expected requirements.
