Cell separator fly-cut mechanism

A cell separator fly-cut mechanism, comprising a first driving component, a second driving component, a lamination component and a fly-cut component, wherein the lamination component is in transmission connection with the first driving component and is configured to perform linear reciprocating motion along a preset direction under driving of the first driving component to move close to or away from a winding needle, the lamination component is configured for rolling and pressing the separator on the winding needle;

• the fly-cut component is in transmission connection with the second driving component and is configured to perform linear reciprocating motion along the preset direction under driving of the second driving component to move close to or away from the separator, and the fly-cut component comprises a fly-cut connecting frame, a rotary driving component, a rotary shaft and a cutter, the fly-cut connecting frame is in transmission connection with the second driving component, the rotary driving component is arranged on the fly-cut connecting frame, and the rotary shaft is rotatably arranged on the fly-cut connecting frame and is in transmission connection with the rotary driving component for rotating relative to the fly-cut connecting frame under driving of the rotary driving component;
• the cutter is arranged at a surface of the rotary shaft, wherein the cutter, when being close to the separator, clings to a surface of the winding needle, and at the same time, the separator rotates along with the winding needle, and the cutter is configured for moving in synchronization with the separator under driving of the rotary shaft and cutting off the separator in situation of being at a speed same as a speed of the separator.
