Abstract

The invention discloses a battery core stacking clamp, which comprises a support plate. The support plate is provided with at least one placement platform for stacking battery cores and a floating pressing device for applying pressure to a group of battery cores and making the battery cores prop against a limiting block of each placement platform; the support plate is parallel to the horizontal plane in a first state; the support plate and the horizontal plane keep an acute angle in a second state; and each limiting block in the second state is lower than that in the first state. The battery core stacking clamp is ingenious in design; the support plate can be switched between the horizontal state and the inclined state, so that the inclined state can be kept when the battery cores are stacked, and the battery cores are prevented from dumping; the battery cores are switched into the horizontal state after stacking is completed and thus can be directly transported to the next station for processing, integration with equipment in other procedures is facilitated, and the problem of a single function of stacking equipment is solved; and meanwhile, the condition that the battery cores do not dump when switched into the horizontal state from the inclined state can be ensured in combination with the floating pressing device.
