Description

Technical Field

[0001] The utility model relates to the technical field of electrode sheet cross-section cutting, and specifically, to an electrode sheet cutting device. Background Art

[0002] There are various types of electrode sheets, including capacitor electrode sheets, battery electrode sheets, conductive electrode sheets, self-adhesive electrode sheets, adhesive electrode sheets, non-woven fabric electrode sheets, electrocardiogram electrode sheets, silicone electrode sheets, heating electrode sheets, etc. Electrode sheets can be classified into different types according to different standards. For example, self-adhesive electrode sheets can be classified by material into: 1. PET self-adhesive electrode sheets; 2. silicone self-adhesive electrode sheets; 3. silicone self-adhesive electrode sheets; 4. other button self-adhesive electrode sheets; silicone electrode sheets can be classified by use into water-absorbing electrode sheets, heating electrode sheets, conductive electrode sheets, etc. In addition to electrode sheets, there are also electrode wires and related products. When winding lithium battery cells, it is necessary to automatically wind the next cell after one cell is wound. It is necessary to develop an automatic electrode sheet cutting device and an automatic electrode sheet conveying device to automatically convey the electrode sheet into the core to achieve continuous automatic winding of the cell.

[0003] During the use of the electrode sheet, it is necessary to cut the electrode sheet, so cutting equipment is required. The traditional methods are divided into two types. One is manual, cutting by holding a tool by hand. The second is to drive a horizontally placed blade to cut the electrode sheet by the extension of a hydraulic rod in a similar extrusion manner. The traditional method uses extrusion cutting. During the cutting process, the entire blade surface is in horizontal contact with the electrode sheet surface, so it is called extrusion cutting. Although this method can cut quickly during cutting, when the entire blade surface contacts the aluminum foil paper, it will push the electrode sheet out to the opposite side. After the electrode sheet is pushed out by the pushing force, wrinkles will form on its surface, and the wrinkles will cause the appearance of the electrode sheet to be unsightly. Therefore, the practicality of this method is relatively poor. For this reason, an electrode sheet cutting device is proposed.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model
