This utility model relates to the field of battery electrode sheets and discloses a self-calibration and positioning device for battery rolling rollers. It includes a positioning platform with a hollow side wall and a lifting frame embedded within it. A top plate is horizontally fixed to the top of the lifting frame. A straight rod is fixedly connected to the top of the positioning platform, and a cylinder is fixedly connected to the middle of the straight rod. A retainer is fixedly connected between the top of the cylinder and the top plate. Slider blocks are sleeved on both sides of the straight rod, and a tripod is hinged to the top of each slider. A connecting seat is hinged to the top of the tripod, and the top of the connecting seat is fixed to the bottom of the top plate. Bearing seats are fixedly connected to the bottom of both sides. This self-calibration and positioning device for battery rolling rollers, by incorporating the lifting frame, achieves stable and adjustable lifting and real-time self-calibration positioning of the upper rolling roller relative to the lower rolling roller, eliminating the need for manual disassembly and assembly. This improves electrode sheet thickness control and solves the problem that traditional drilling positioning structures cannot dynamically adjust the rollers.
