Die-cutting equipment for lithium battery electrode material processing

Abstract

The invention relates to die-cutting equipment for lithium battery electrode material processing. The die-cutting equipment for lithium battery electrode material processing comprises a fixed frame, aflat-pressing device and a die-cutting device; the fixed frame is of a U-shaped structure; the flat-pressing device is mounted on the left side in the fixed frame; the die-cutting device is arrangedon the right side of the flat-pressing device; and the die-cutting device is mounted on the right side in the fixed frame. According to the die-cutting equipment for lithium battery electrode materialprocessing, the difficult problems that the phenomenon that burrs are easily produced at the edges and corners of an electrode material when stamping and cutting are performed because the electrode material is commonly cut in a stamping mode, the edge cutting effect of the electrode material is poor and the electrode material is cut unevenly to affect subsequent processing and using of the electrode material, moreover, a motor is prone to cumulative errors because a stepping motor is commonly adopted for driving and stretching when the electrode material is subjected to fixed-length stretching, and the fixed length may be inaccurate after long-time use, so that the phenomenon that the lengths of the cut electrode materials vary is easily caused when the electrode material is cut by the existing equipment can be solved.

Description

technical field [0001] The invention relates to the field of lithium battery processing equipment, in particular to a die-cutting equipment for lithium battery electrode material processing. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become the mainstream; the positive electrode of the lithium battery includes a current collector composed of lithium cobalt oxide (or lithium cobalt manganate, lithium manganate, lithium iron phosphate, etc.) It consists of a current collector composed of graphitized carbon material and copper foil. [0003] At present, the existing equipment usually has the following defects when di...

Problems solved by technology

[0005] The present invention can solve the problem that when the existing equipment cuts the electrode material, the electrode material is usually cut by punching. However, when punching and cutting, it is easy to cause burrs on the corners of the electrode material, and the cutting effect of the electrode material is poor. Uneven cutting affects the subsequent processing and use of electrode materials. When stretching electrode materials to a fixed length, a stepping motor is usually used to drive the stretching. Accurate, making the electrode material after cutting prone to problems such as uneven lengths
