Technical Field

[0001] The utility model belongs to the technical field of lithium battery diaphragm production, and specifically relates to laser cutting equipment for lithium battery diaphragm production. Background Art

[0002] In the structure of lithium batteries, the diaphragm is one of the key internal components. The performance of the diaphragm determines the interface structure and internal resistance of the battery, and directly affects the battery's capacity, cycle and safety performance. A diaphragm with excellent performance plays an important role in improving the overall performance of the battery. The main function of the diaphragm is to separate the positive and negative poles of the battery to prevent the two poles from contacting and short-circuiting. In addition, it also has the function of allowing electrolyte ions to pass through. The diaphragm material is non-conductive, and its physical and chemical properties have a great influence on the performance of the battery. In the production process of lithium battery diaphragms, the diaphragms need to be cut into sizes and shapes that meet the use requirements. With the development of laser technology, the application of lasers has become more and more extensive. Laser cutting is one of the thermal cutting methods, so laser cutting equipment is usually used for cutting lithium battery diaphragms.

[0003] In the existing technology, when laser cutting equipment is used to cut lithium battery diaphragms, workers have to manually move the position of the diaphragms. If the operation is not careful, the laser cutting equipment may accidentally injure them, posing a safety hazard. At the same time, when laser cutting equipment is used to cut lithium battery diaphragms, harmful gases containing fluoropolymers will be generated. These gases will be directly discharged into the external air, causing pollution to the working environment, and will have an impact on the health of workers if inhaled.

[0004] Therefore, a laser cutting device for lithium battery diaphragm production is needed to solve the problems in the prior art of workers manually moving the diaphragm, which poses a safety hazard, and the generation of harmful gases that pollute the working environment during cutting.
