AI Technical Summary
In existing technologies, during the encapsulation process of soft-pack cells for new energy batteries, the adhesive on the tabs is exposed after the top of the cell is sealed due to the close spacing between the two pits. Using tab preheating clamps is not effective in clamping the cells and cannot effectively prevent them from moving forward, resulting in encapsulation abnormalities.
A soft-pack battery cell assembly and clamping fixture was designed, comprising a drive mechanism, a tab preheating mechanism, and a cell clamping mechanism. The tab preheating clamp is driven by a cylinder and a slide rail to clamp the battery cell tabs, and the battery cell is clamped and assembled using a slide cylinder and a pressure bar to ensure the packaging effect.
It improves the efficiency of pouch cell assembly, reduces the defect rate, is simple to operate and low in cost, and ensures the stability and reliability of the packaging effect.
