[0002] Currently, most of the tab production lines are single production lines, which complete the automated production of tabs by laminating a single metal strip → heating it multiple times → cutting it into a single plate tab → chamfering the tabs. For example, patent number CN202122824474.6 is a linear production line for power tabs. The production mode of this single production line is to produce one tab from one strip. The average production cycle of a single tab is more than 7 seconds. The cost of a single device is high, and the production cycle time is long, making it difficult to adapt to the existing market. Moreover, this production line does not position the tab to be chamfered before chamfering, resulting in processing errors and affecting the tab yield. Therefore, there is an urgent need to produce a dual-piece positioning device for solid-state battery tabs, which can simultaneously initially position the two plate tabs produced on two linear production lines before chamfering, reduce processing errors, and increase the tab production cycle from 7 seconds per tab to 7 seconds for two tabs, thereby improving processing efficiency.
