1、lithium battery electrode manual die cutting machine working principle
(1) Basic structure
Lithium battery electrode manual die cutting machine is usually composed of die cutting knife, knife holder, workbench, pressure adjustment device, positioning system and other parts. The die cutter is the core component, and its shape and sharpness directly determine the precision and effect of cutting. The tool holder is used to hold the die cutter and ensure its stability during the cutting process. The table provides a surface for electrode placement and operation, and generally has good flatness and wear resistance. The pressure regulating device can adjust the pressure of the die cutter on the electrode according to the different characteristics and cutting requirements of the electrode material to achieve the best cutting effect. The positioning system is responsible for accurately determining the cutting position of the electrode and ensuring that the size of the electrode after cutting meets the design standard.
(2) Cutting process
At work, the operator first places the lithium battery electrode to be cut on the work table and fixes it precisely at the predetermined cutting position through the positioning system. Then, according to the thickness and hardness of the electrode material and other parameters, adjust the pressure adjustment device, set the appropriate die-cutting pressure. Then, the die cutting machine is started, and the die cutting knife cuts the electrode under pressure. Because the shape of the die cutter matches the shape of the required electrode, the electrode can be cut into a variety of complex shapes, such as round, square, rectangular, etc., and can ensure the uniformity and smoothness of the cutting edge.
