Novel bottom plate device for high-capacity lead storage battery plate group welding fixture

The utility model provides a novel bottom plate device for a high-capacity lead storage battery plate group welding fixture. The device comprises a roller bottom plate and a collecting container, a pole group is placed above the roller bottom plate, and the collecting container is placed below the roller bottom plate; the roller bottom plate is composed of a plurality of rollers which are horizontally arranged. According to the utility model, the roller bottom plate consisting of a plurality of rollers which are horizontally arranged is used as the bottom plate of the storage battery plate group welding fixture; lead slag falling off during plate group welding falls down along with rolling of the roller and is difficult to remain on a bottom plate of the roller, the hidden danger of shortcircuit of a battery due to the fact that the lead slag is clamped by the plate group is eradicated, the lead slag falling down is recycled by the collecting container and can be reused, and the laborintensity of workers for
