The invention relates to an automatic assembly line for a storage battery plate package machine. The automatic assembly line comprises a machine tool, a pole group arrangement mechanism, a motor and a central control computer, wherein an annular chain is arranged on a machine tool; chain wheels are arranged in the annular chain; a plurality of trays are arranged on the surface; the pole group arrangement mechanism is arranged at the tail of the machine tool; the pole group arrangement mechanism comprises a rack; the rack comprises an engine base, a support arm and a horizontal frame; a first double-shaft cylinder and a second double-shaft cylinder are arranged on the horizontal frame; the first double-shaft cylinder and the second double-shaft cylinder are vertically arranged; and two ends of the first double-shaft cylinder and the second double-shaft cylinder are connected with a first clamping plate assembly and a second clamping plate assembly respectively. The automatic assembly line is high in automatic degree and comprises the pole group arrangement mechanism, so that the pole group arrangement speed is high; the uniformity effect is good; pole plates are prevented from being staggered; the production efficiency is improved; the pole plates are prevented from being contacted by an operator to harm the physical health; and the automatic assembly line is relatively environment-friendly.
