  • Patent number: 11942610
    Abstract: The present invention relates to a pitch-variable battery fixture and a battery cell formation apparatus having the same. A pitch of clamping plates of a plurality of clamping blocks is increased by a slide actuator of the pitch-variable battery fixture, and then the clamping plates are inserted into a plurality of compartments of a battery tray. The clamping plates are urged to clamp batteries by the slide actuator. The battery tray is provided for placement of the batteries, and a compressing force is exerted for shaping the batteries during a battery cell formation. The pitch-variable battery fixture is provided for clamping batteries having different thicknesses. According to the actual thickness of each battery, the thickness of the formed battery can be shaped.
