Battery cell stacking device

The utility model provides a battery cell stacking device which comprises a carrying mechanism, a caching mechanism, an overturning mechanism and a stacking mechanism, the carrying mechanism is used for caching battery cells to be stacked on the caching mechanism in a horizontal state, and the gluing surfaces of the battery cells face upwards; the temporary storage mechanism is connected to a movable part of the turnover mechanism, and the turnover mechanism is used for driving the temporary storage mechanism to turn over towards the stacking mechanism, so that the battery cells are turned over from a horizontal state to a vertical state, and the turned battery cells are stacked on the stacking mechanism; the caching mechanism is further used for being matched with the stacking mechanism to press the multiple battery cells stacked on the stacking mechanism from the two sides so as to form a battery cell module. Through cooperation of the carrying mechanism, the temporary storage mechanism, the turnover mechan
