description The invention relates to the technical field of solar cell preparation. The invention relates to a chain-type alkali polishing production line and a chain-type alkali polishing method for a crystalline silicon battery piece. The chain-type alkali polishing production line comprises a closed box, the closed box is internally provided with a feeding system, a first acid pickling system, a first water washing system, a first polishing system, a second polishing system, a second water washing system, a second acid pickling system, a third water washing system, a drying system and a discharging system which communicate with one another, wherein each of the first acid pickling system and the second acid pickling system comprises an acid storage tank filled with a hydrofluoric acid solution. Theinvention further discloses a chain-type alkali polishing method for the crystalline silicon battery piece. According to the production line, only the hydrofluoric acid solution is used as the cleaning solution in the acid pi
