[0035] After the laser welding is completed, the output shaft of the first motor 10 is controlled to rotate reversely, the two first lead screws 9 are driven to rotate reversely synchronously through the transmission connection of the two first belt pulley assemblies 11, further drives the lifting frame 3 to move upwards, thereby drives the correction frame 4 to move upwards synchronously to reset.
