Electrode sheet turning mechanism

An electrode sheet turning mechanism, comprising a frame, a housing, a conveyor belt, a driver, a stripper, and a gas pump;

• wherein the housing is mounted on the frame, and has a suction cavity;
• an arc-shaped guide surface is formed on the housing;
• in an extension direction of the arc-shaped guide surface, a material feeding region is formed on an upper side of the arc-shaped guide surface, and a material discharging region is formed on a lower side of the arc-shaped guide surface;
• a plurality of first suction holes disposed in a staggered manner are provided on the arc-shaped guide surface;
• the first suction holes communicate with the suction cavity and an exterior;
• the gas pump is configured for drawing a gas in the suction cavity;
• the conveyor belt is configured for conveying an electrode sheet, and a plurality of second suction holes disposed in a staggered manner run through the conveyor belt;
• the conveyor belt is further tightly wound on the arc-shaped guide surface, and is operative to seal the first suction holes;
• the driver is configured for driving the conveyor belt to move in the extension direction of the arc-shaped guide surface;
• and when the electrode sheet passes through the material discharging region along with the conveyor belt, the stripper is configured for guiding the electrode sheet to move in a direction away from the conveyor belt, so that the electrode sheet is stripped away from the conveyor belt;
• wherein the conveyor belt is wrapped around the housing and rotatable around the housing when driven by the driver;
• wherein pore size of the second suction holes is smaller than pore size of the first suction holes.
