The invention relates to the technical field of lead-acid battery production, and particularly discloses a lead-acid storage battery intelligent full-automatic cast-weld production line and a processthereof. In the production line, lead-acid batteries are transferred, conveyed, cut and machined through mutual cooperation of cutting equipment, a second grabbing manipulator, a conveying line and atransferring manipulator, and alternative automatic loading and unloading work of a plurality of groups of cast-weld machines is realized, so that the technical problem of low machining efficiency during the automatic processing of existing lead-acid batteries is solved. In the process, the transferring, conveying and cutting of the lead-acid batteries are realized through automatic tight joint ofa cutting step and a cast-weld step, and alternative automatic loading and unloading work of the plurality of groups of cast-weld machines is realized, so that the plurality of groups of cast-weld machines can perform cast-weld machining simultaneously; the machining efficiency is improved; and the technical problem of low machining efficiency in the automatic machining process of the existing lead-acid batteries is solved.
