A cell clamping mechanism comprises a mounting base, a die clamp, a pinch roller clamp and a driving assembly; the die clamp and the pinch roller clamp are hinged on the mounting base through hinge pins; the die clamp comprises a first chuck and a first chuck which are arranged in opposite; a first clamping groove and a first movable hole which penetrates through the first clamping groove and is communicated with the first clamping groove are formed in the first chuck; a second clamping groove and a second movable hole which penetrates through the second clamping groove and is communicated with the second clamping groove are formed in the second chuck; the pinch roller clamp comprises a first pinch roller and a second pinch roller which are arranged in opposite; the first pinch roller passes through the first movable hole to be formed in the first clamping groove; the second pinch roller passes through the second movable hole to be formed in the second clamping groove; and the driving assembly is hinged on the mounting base and used for driving the first chuck and the second chuck to move close to each other or far from each other, and for driving the first pinch roller and the second pinch roller to move close to each other or far from each other. The cell clamping mechanism can improve the cell quality as well as improve the automatic production of batteries. The invention also relates to a battery manufacturing apparatus.
