Abstract

The invention discloses a lithium ion battery lead anti-bending adjustment assembly and a fixture, which belong to the technical field of lithium ion battery devices. In the specific scheme, the lithium ion battery lead anti-bending adjustment assembly comprises a PCB, a PCB mounting board, a wedge block, a main board and a pressing block, wherein the PCB is fixedly mounted on the upper surface ofthe PCB mounting board; the upper surface of the wedge block is in sliding connection with the lower surface of the PCB mounting board; the lower surface of the wedge block is in sliding connection with the upper surface of the main board; the pressing block is mounted on the lower surface of the main board; and the wedge block moves left and right to push the PCB mounting board and the main board to move to opposite directions. The PCB vertical direction and the battery thickness direction can be adjusted, the lead of the battery during formation and capacity grading processes is ensured notto be bent, the problems of battery short circuit, poor battery voltage, poor capacity and the like caused by bending of the lead are improved, and the lithium ion battery formation and sorting yieldis improved.

Description

technical field [0001] The invention belongs to the technical field of lithium-ion battery equipment, and in particular relates to a lithium-ion battery lug anti-bending adjustment assembly and a clamp using the adjustment assembly. Background technique [0002] Most of the existing soft-pack lithium-ion battery automatic hot-press formation and capacity separation equipment use formation cardboard to cover the battery formation. When replacing the next type of battery for production, the position of the battery tabs is different in the vertical direction and the battery thickness direction. Variety. However, the PCB board in contact with the lug on the layer board of the existing formation and capacity separation fixture can only change the position in the vertical direction, and the position in the thickness direction of the battery remains unchanged, resulting in the formation and capacity separation fixture pressing the battery. The phenomenon of battery tab bending, wh...
