The battery electrode die-cutting machine is a key equipment for precision machining of the electrode sheet in the battery production process, which cuts the electrode sheet into a specific shape and size through the die-cutting process to meet the requirements of the battery assembly.
The working principle of the battery electrode die-cutting machine is based on the stamping principle. After the equipment is powered on and started, the motor drives the transmission system and drives the die cutter plate to move up and down quickly. When the electrode sheet placed on the workbench enters the die cutting area, the die cutting knife plate under the action of pressure, like scissors quickly cut into the electrode sheet material, according to the pre-designed mold profile, the electrode sheet is cut into the required shape, while completing fine processing such as drilling, cutting edge, to ensure the dimensional accuracy and shape accuracy of the electrode sheet.
Structurally, it is mainly composed of the following parts. The power system is the motor, which provides sufficient power for the die-cutting process to ensure that the die-cutting plate can quickly and powerfully complete the cutting action. The transmission system is responsible for converting the rotating motion of the motor into the up and down linear motion of the die cutter plate, and the common transmission methods are crank connecting rod mechanism, CAM mechanism, etc., to ensure the smoothness and accuracy of the movement. Die cutting tool plate is the core component, according to different electrode shape and size requirements customized, made of high-quality steel, after precision machining and heat treatment, with high hardness, high wear resistance and good cutting edge retention. The table is used to carry the electrode sheet and is equipped with a high-precision positioning device to ensure the accurate position of the electrode sheet during the die cutting process. The control system integrates all kinds of sensors and operation interface, the operator can precisely set the pressure, speed, stroke and other parameters of die cutting through it, to achieve automatic and intelligent die cutting operation.
The device has a number of performance features. Its die-cutting precision is very high, can control the size error in a very small range, ensure the consistency of the electrode sheet, and improve the assembly quality of the battery. Die-cutting speed is fast, high production efficiency, and multiple die-cutting operations can be completed per minute to meet the needs of large-scale production. Moreover, the equipment has good stability and can maintain reliable operation in long-term continuous work.
When operating the battery electrode die-cutting machine, first of all, according to the specifications of the electrode sheet and die-cutting requirements, set the relevant parameters in the control system, such as die-cutting pressure, speed, stroke, etc. Then the electrode sheet is placed on the work table, and the positioning device is used for accurate positioning. Then start the equipment, and the operator closely observes the die cutting process to ensure the normal operation of the equipment. After the die cutting is completed, the electrode sheet is taken out for quality inspection to check whether the dimensional accuracy, shape accuracy and incision quality meet the standards.
