Abstract: In order to weld the heating plate and nail in the electric kettle, the automatic resistance welding equipment was designed. The equipment consisted of heating plate feeding mechanism, nail feeding mechanism, the assembling and clamping fixture, resistance welding machine. The batching heating plate and nail were fed on the hopper by human, and then the feeding mechanism took each part and automatic assemblied. After being positioned and clamped by the fixture, the specimen was transport to the welding station, and was automatically welded. The result of simulated production showed that the equipment realized automatic production, and saved 3 human consumption.
