Abstract

The invention discloses a stretching device for a lithium battery diaphragm. A base, a second guide roller, a preheating box and clamps are included, a cover body is fixed to the top of the base, the second guide roller is arranged in the center of one side of the interior of the cover body, and first guide rollers are arranged at the positions, on the two sides of the second guide roller, in the cover body; and fixing grooves are evenly formed in the two sides of the end, away from the second guide roller, of the top of the base, threaded lead screws are arranged in the fixing grooves correspondingly, the threaded lead screws are sleeved with driving blocks correspondingly, adjusting arms are hinged to the two sides of each air cylinder correspondingly, and the clamps are arranged on the adjusting arms correspondingly. By installing the base, the cover body, the first guide rollers, the second guide roller, the fixing grooves, the threaded lead screws, the driving blocks, hydraulic telescopic rods, the air cylinders, telescopic columns, connecting rods, the adjusting arms and the clamps, the diaphragm can be stretched more comprehensively and thoroughly, the smoothness of the diaphragm is improved, and the stretching quality of the diaphragm is improved.

Description

technical field [0001] The invention relates to the technical field of production and processing of lithium battery diaphragms, in particular to a stretching device for lithium battery diaphragms. Background technique [0002] Lithium battery separator is a layer of separator material between the positive electrode and the negative electrode. The performance of the separator determines the interface structure and internal resistance of the battery, which directly affects the capacity, cycle times and safety performance of the battery. The separator with excellent performance It plays an important role in improving the overall performance of the battery. During the production and processing of the lithium battery separator, it needs to be stretched to improve its flatness. However, most of the existing stretching devices have simple structures and single functions. The specific existence is as follows question; [0003] 1. Most of the existing stretching devices can only str...
