Description

Technical Field

[0001] This invention relates to the field of battery electrode processing technology, and in particular to a device for cutting aluminum alloy strips for battery electrodes to a fixed length. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as the positive / negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use require very strict environmental control. With the development of science and technology, lithium-ion batteries have become the mainstream technology.

[0003] Lithium batteries have many structures, one of which is the battery electrode. During the manufacturing process, the battery electrode is usually made of aluminum alloy strip and processed into standard size. Then, the standard-sized aluminum alloy blocks are further processed separately. In order to facilitate the processing of aluminum alloy strip into standard size, some cutting devices have been invented.

[0004] The utility model patent with authorization announcement number CN215468368U, entitled "A Fixed-Length Cutting Device for Strip of High Initial Permeability Current Transformer Core Alloy," utilizes a threaded adjusting rod, a pressure sensor, and a scale. Rotating the threaded adjusting rod causes a slider to slide within a groove. As the slider slides, a baffle moves synchronously, thus adjusting the cutting size. The pressure sensor ensures that one end of the strip is in contact with the baffle, improving cutting accuracy, while the scale measures the position of the adjusting baffle. This invention solves the problem of poor cutting efficiency when cutting strips to different sizes.

[0005] The solutions described in the aforementioned patents all have certain drawbacks in use. In practice, the strip material is directly cut to a fixed length. However, in actual use, the width of the strip material is usually 500-600mm for easy placement. Therefore, the strip material needs to be processed into strips with equal spacing during processing. Existing technologies often stack the processed products before cutting, which requires two additional processes: stacking and cutting. This incurs certain costs, and the equipment angle and site requirements are relatively high, which does not meet people's usage requirements.

[0006] Therefore, based on the inventor's extensive experience in design, development and actual manufacturing in the relevant industry over many years, the inventor has researched and improved the existing structure and its shortcomings, and provided a fixed-length cutting device for aluminum alloy strips for battery electrodes, in order to achieve a more practical purpose. Summary of the Invention

[0007] To address the issue mentioned in the background art, existing devices directly cut the strip to a fixed length during use. However, in actual use, for ease of placement, the strip width is typically 500-600mm. Therefore, during processing, the strip needs to be processed into equally spaced strips. Existing technologies often involve stacking the processed products before cutting, which requires two additional steps: stacking and cutting. This incurs costs, and the equipment angle and site requirements are relatively high, failing to meet user needs. Therefore, this invention provides a fixed-length cutting device for aluminum alloy strips used in battery electrodes.
