Steel ball hitting device for lithium ion battery

The invention relates to a steel ball hitting device for a lithium ion battery, which includes a rotating platform, and a feeding mechanism, a liquid injection port identifying mechanism, a steel balltaking mechanism, a steel ball pressing mechanism, a steel ball detecting mechanism, and a blanking mechanism arranged in turn around the rotating platform. The design concept of a turntable is adopted, the rotating platform is used as a device center, a battery clamp is fixed on the rotating platform to cooperate with each operation station, each operation station arranged around the rotating platform adopts a modular design, installation control inputted to the device can be saved to the maximum degree, the cost and the energy consumption are reduced, the whole device is more compact and orderly, and the occupied land is saved; and along with rotation of the rotating platform, the operation stations can synchronously, continuously and automatically complete operation steps of battery feeding, battery liquid inj
