The high-efficiency manufacturing platform for all solid state battery composite electrode sheets is mainly composed of an electrode roll unwinding and correction mechanism, a cutting mechanism, a transfer robot, a double-sided electrolyte 3D printing platform, a flipping mechanism, an intelligent drying mechanism, a discharging mechanism, and a receiving mechanism. It can efficiently achieve high-precision printing and intelligent drying of positive/negative electrode sheet double-sided composite electrolytes, lithium metal negative electrode sheet double-sided composite electrolytes, and automatically complete the separation and collection of composite electrode sheets, fully supporting the industrial manufacturing of all solid state batteries.
