Abstract: A dimension detection apparatus configured to detect a composite electrode plate. The composite electrode plate includes a plurality of continuous first electrode plates, a plurality of second electrode plates, and two insulators. The first electrode plates are of an opposite polarity to the second electrode plates. The plurality of first electrode plates are sandwiched between the two insulators and arranged in parallel along an extension direction of the insulators. The plurality of second electrode plates are arranged alternately on outer sides of the two insulators along the extension direction of the insulators, and correspond one-to-one to the plurality of first electrode plates. The dimension detection apparatus includes: two shooting assemblies, disposed on two sides of the composite electrode plate respectively along a thickness direction, and configured to photograph two adjacent second electrode plates respectively.
