Abstract

The invention discloses a cutting mechanism of a battery pole piece. The cutting mechanism comprises a mounting plate, a cross roller guide, a guide sliding plate, a rotating shaft, a cutter mounting plate, an upper cutter, a lower cutter, a regulating lever and the like. The cutting mechanism of the battery pole piece provided by the invention can be used for maximally minimizing the wears of the upper cutter and the lower cutter by using the high-rigid precision guide of the cross roller guide; meanwhile, the regulating lever and a spring on the regulating lever are utilized to ensure the upper cutter to be flexibly adhered to the lower cutter and automatically compensate the wears, thus effectively controlling the size of burrs in the process of cutting the battery pole piece.

Description

technical field [0001] The invention relates to a cutting mechanism, in particular to a battery pole piece cutting mechanism. Background technique [0002] Lithium batteries are widely used in mobile communication devices and portable electronic devices because of their advantages such as high energy density, high output power, long cycle life, and no environmental pollution. In the production process of lithium batteries, the battery pole pieces are cut and wound with separators to form batteries. When cutting the pole piece, cut the pole piece with the upper and lower cutters, and burrs will be formed on the cross-section of the metal body of the pole piece. When the burr of the pole piece exceeds a certain size, it will pierce the diaphragm inside the battery, causing the positive and negative electrodes of the battery to break out. short circuit, causing safety hazards. Therefore, it is necessary to provide a suitable pole piece cutting mechanism, which can effectively...
