Battery module extrusion device

A battery module extrusion device provided by the invention comprises a device body, a baffle plate part and a driving part. The driving part is arranged on the device body, and the baffle plate part is detachably connected with the driving part. The driving part is used for driving the baffle plate part to move along a preset direction so as to extrude a battery cell with expanded volume to recover the original shape, so that the purpose of limiting the size of a battery module within a preset size is achieved. 本申请提供的电池模组挤压装置中，包括装置本体、挡板件以及驱动件；驱动件设置于所述装置本体，所述挡板件与所述驱动件可拆卸连接，其中，驱动件用于驱动所述挡板件沿预设方向移动，继而挤压体积发生膨胀的电芯，使其恢复原有的形状，以达到将电池模组的尺寸限定在预设尺寸内的目的。
