Automatic positioning device for battery cell welding

The invention discloses a battery cell welding automatic positioning device which comprises a rack and a carrying seat, a positioning assembly is arranged on one side of the carrying seat and at least comprises symmetrically-arranged rollers, the outer circumferential surfaces of the rollers abut against the outer circumferential surface of a battery cell all the time, and a limiting assembly used for limiting the battery cell is arranged on the other side of the carrying seat. The limiting assembly at least comprises a rotating wheel, and the outer circumferential surface of the rotating wheel always abuts against the outer circumferential surface of the battery cell; a driving assembly for supporting the battery cell and driving the battery cell to rotate is arranged below the carrying seat, and a pressing assembly is arranged above the carrying seat. The device has the main beneficial effects that the design is exquisite, the roller and the limiting wheel are always propped against the outer circumferentia
