Claim 8:
9. An automatic material changing and welding method for stamping materials, using the automatic material changing and welding system for stamping materials according to claim 1, and comprising:
driving, by a welding platform, a first stamping material and a second stamping material to move into a stamping machine from a welding feed end through a welding discharge end along a same path;
sensing, by a proximity switch arranged at the welding feed end, the first stamping material, and when the proximity switch does not sense the first stamping material, generating a material changing signal;
controlling, by a control unit, the welding platform according to the material changing signal to enable a tail end of the first stamping material to stop above the welding platform between the welding feed end and the welding discharge end, and enable the automatic feeding machine to drive a front end of the second stamping material to stop above the welding platform, wherein the tail end of the first stamping material and the front end of the second stamping material are adjacent but are not overlapped;
when the proximity switch does not sense the first stamping material, clamping and fixing, by two material clamping pneumatic cylinders arranged at the welding discharge end, the first stamping material;
sucking, by a welding connection plate suction apparatus, a welding connection plate and placing the welding connection plate above the welding platform;
enabling, by a driving mechanism of a welding transfer sliding table, an electric welding machine to execute a welding procedure to connect the welding connection plate, the tail end of the first stamping material and the front end of the second stamping material to each other, thereby completing automatic material changing and welding; and
resetting, by the driving mechanism, the electric welding machine after the automatic material changing and welding is completed.
