Battery piece transmission line and battery string production line

The invention relates to the technical field of solar cell string production, in particular to a cell piece transmission line and a cell string production line. The battery piece transmission line comprises a transmission belt, an aligning device, a carrying device and a bearing platform, the conveying belt is used for conveying the fragmented battery pieces, the two ends of the fragmented battery pieces extend out of the conveying belt, and the bearing table is in butt joint with the output end of the conveying belt. The correcting devices are arranged on the two sides of the output end of the conveying belt and can push the fragmented battery pieces to be close to the two right-angle sides of the bearing table, so that the fragmented battery pieces are corrected; and the carrying device can carry the aligned fragmented battery pieces to the bearing table in a reciprocating manner. The battery string production line comprises a diaphragm transmission line, a transfer device, a conveyor belt, a belt manufactu
