and step S3, the formed soldering tin sequentially bypasses the tension wheel and the guide wheel, and is further conveyed to the shearing mechanism through the feeding mechanism, and then the servo motor and the shearing knife are started to operate, so that the continuous shearing preparation of the soldering tin sheet is completed.
