Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lithium battery diaphragm cutting, in particular to a cutting device for lithium battery diaphragm processing. Background Art
[0002] Lithium battery separator is a material used to separate the positive and negative electrodes. It can prevent direct contact between the positive and negative electrodes, prevent current short circuit, and allow lithium ions to move freely in the battery. Lithium battery separators are generally made of polymer materials, such as polypropylene film. This film has high chemical and electrochemical stability and can withstand the high temperature and strong acid and alkali environment in lithium-ion batteries.
[0003] During the processing of lithium battery separators, the entire piece of lithium battery separator needs to be cut, so a cutting device is required.
[0004] In the process of cutting lithium battery diaphragms, the lithium battery diaphragms need to be fixed. If the diaphragms are not fixed, it is easy to cause the diaphragms to move or deform, affecting the accuracy of cutting and the quality of the finished product. In order to ensure the stability and accuracy of the cutting process, clamps or other fixing devices are usually used to fix the diaphragms to keep them stable and tight. However, when fixing the lithium battery diaphragms, clamping too tightly may cause damage to the diaphragms. If the clamping force is too large, the diaphragms are easily over-compressed, torn or damaged, thus affecting the performance and service life of the diaphragms. To address this problem, we propose a cutting device for lithium battery diaphragm processing. Utility Model Content
