[Abstract]:With the rapid development of advanced manufacturing technology, automatic welding of headphone terminals has become an inevitable trend. Solder robot can greatly improve people's working environment, improve welding efficiency, save enterprise cost and increase the competitiveness of enterprises in engineering practice. The physical prototype of the automatic soldering machine for headphone terminals was developed by integrating structural design and electronic control design. Based on the Ansys simulation technology and orthogonal test, the welding process and welding parameters of the automatic soldering of headphone terminals were determined. Firstly, based on the functional requirements and technical specifications of the automatic soldering machine for headphone terminals, the processing procedure, basic flow and design difficulties are analyzed, and the overall design scheme is determined. Secondly, according to the structure characteristics of earphone terminal and enamel wire, the detailed scheme design of soldering machine is carried out. Through the calculation, analysis and reliability test of the key parts, the design scheme of each module is determined, including vibration feeding module, rotation identification module, automatic welding module, welding line pre-processing module and so on. Thus, the design of the whole machine model and the final preparation of the physical prototype are completed. Thirdly, an automatic control system with high efficiency, high precision and good stability is developed by combining Panasonic PLC with Hetak human-computer interface (touch screen), which can meet the requirements of automatic welding of headphone terminals. Finally, the simplified model is introduced into the simulation analysis software Ansys, and the key parts are simulated and simulated to provide guidance for the determination of the key parameters in the welding process. The key parameters of automatic welding of earphone terminal are determined by orthogonal test. Based on the automatic soldering machine developed by headphone terminal, this paper has realized the breakthrough of this kind of welding equipment from nothing to existence in our country. This product will help to solve the problems of poor product consistency, high labor cost and low production efficiency in manual soldering. It also provides reference and guidance for the development of automatic welding equipment and welding technology for special-shaped cylindrical terminals similar to earphone terminals.
