A label peeling device includes a mounting bracket, a power member attached to the mounting bracket, a driving member driven by the power member; and a pressing assembly coupled to a first end of the driving member. A clamping mechanism includes a sliding member coupled to a second end of the driving member, and a clamping assembly configured to clamp a backing paper. A first resisting member is attached to the mounting bracket, and presses against the clamping assembly. The pressing assembly and the clamping mechanism are configured to be urged toward each other by a driving force imparted by the power member, the first resisting member drive the clamping assembly to the sliding member, and thereby cause at least one of the plurality of wafers to be removed from the backing paper.
