The invention discloses a
pole piece cold-pressing device for
lithium battery production. The device comprises an installing plate, a flat plate, a first vertical plate, fixed strips, round holes, concave holes, iron rods,
mating holes, springs, an
electromagnet, sliding slots, sliding blocks, a first roller, a first connecting shaft, fixed plates, a second vertical plate, a second roller, a screw, a ball nut, a
lantern ring, a guide rod, a reduction box, a first rotary shaft, a first gear, a second rotary shaft, a second gear, a third gear, a fourth gear, a
servo motor, a second connecting shaft, installing holes, straight pipes, suction nozzles, connecting rods, fixed covers,
distance sensors, connecting pipes, T-pipes, suction motors, a display screen, a single-
chip microcomputer and centrifugal impellers. According to the device, through a lifting structure and the internal structure of the reduction box, ascending and descending of the first roller in the vertical direction can beeffectively realized, therefore, the distance between the first roller and the second roller can be adjusted, a
pole piece can be pressed into a required thickness, and meanwhile the adjusted numbercan be displayed on the display screen in real time.
