发明名称 Lamination device and lamination method
摘要 A lamination device 30 includes a first charger 40 for emitting charged particles toward an uppermost surface of a battery stack 10 of a positive electrode sheet 12, a negative electrode sheet 14, and a separator sheet 16 that are stacked on a stacking stage 32. As a result of the emission of charged particles, the battery stack 10 and one of a positive electrode sheet 12, a negative electrode sheet 14, and a separator sheet 16 that is to be stacked on the stack 10 are electrostatically attracted to each other.

主权项 1. A lamination device for laminating a plurality of sheets to form a stack, the plurality of sheets including a plurality of conductive positive electrode sheets, a plurality of conductive negative electrode sheets, and a plurality of insulating separator sheets, each separator sheet of the plurality of separator sheets being interposed between a positive electrode sheet of the plurality of positive electrode sheets and a negative electrode sheet of the plurality of negative electrode sheets within the stack, the lamination device comprising: a stacking stage on which the plurality of sheets are stacked to form the stack, the stacking stage being formed of a dielectric; a movement mechanism configured to move the stacking stage between (a) a negative electrode line, from which the plurality of negative electrode sheets is supplied, and (b) a positive electrode line, from which the plurality of positive electrode sheets is supplied, wherein the plurality of separator sheets is supplied from the negative electrode line, the positive electrode line, or a combination thereof; a first charger configured to emit charged particles toward the stacking stage, to electrostatically attract the stacking stage to a first sheet of the plurality of sheets, wherein the electrostatic attraction of the stacking stage to the first sheet suppresses positional deviation of the stack with respect to the stacking stage during movement of the stacking stage, and wherein the first charger is configured to emit charged particles toward an uppermost surface of the stack, to electrostatically attract the stack to a next sheet of the plurality of sheets to be stacked on the stack; and a carrier holder configured to move orthogonal to a direction of movement of the stacking stage between the negative electrode line and the positive electrode line, the carrier holder including: a first retainer configured to carry each negative electrode sheet of the plurality of negative electrode sheets between the negative electrode line and the stacking stage; anda second retainer configured to carry each positive electrode sheet of the plurality of positive electrode sheets between the positive electrode line and the stacking stage, wherein the first charger is connected to the carrier holder, and a length of the first charger in the direction of movement of the stacking stage is at least as long as a travel distance of the stacking stage and a width of one of the positive electrode line and the negative electrode line, in the direction of movement of the stacking stage.
