Research on a Special Welding Robot for Earphone Plug

摘要

In order to realize automatic welding of earphone plug, this paper analyzed the current welding process, and developed a special automatic welding robot for earphone plug. The robot was based on rectangular coordinate manipulator, which was driven by stepper motors and integrated the functionality of automatic cutting, automatic dipping tin, automatic feeding, and automatic welding. The robot was simple to operate. It used PLC as core control system and a touch screen for human-computer interface. The experiments proved the robot to be efficient, stable and reliable for earphone plug welding and it was environmental friendly.
