Problems solved by technology

However, the existing shaping mechanism adopts the method of scraping and pressing to shape the tab of the battery cell. After scraping, the surface of the tab of the battery cell will obviously have scratches, and when there are aluminum chips on the surface of the tab of the battery cell, After the scraping head of the shaping mechanism is scraped and pressed, the scraper drives the aluminum chips to move together, leaving scratches on the battery tabs, which damages the battery tabs and increases the defective rate of the battery tabs

Abstract

The invention relates to the field of lithium battery equipment, in particular to a machining apparatus for an electrode ear of an electric cell, which comprises an electrode ear shaping mechanism andan electrode ear cutting mechanism. The electrode lug shaping mechanism comprises a work table, a bearing table, a pressing roller, a first driving assembly, a second driving assembly, a third driving assembly and a cell pressing device. The first driving assembly, the third driving assembly and the cell pressing device are all arranged on the work table. The second driving assembly comprises a first driving member, a first top pressing plate, a first connecting block and a plurality of first elastic members. When the pole ear is shaped by the present application, a rolling mode is adopted instead of a scraping mode, thereby avoiding scratches on the pole ear. As the kpressing roller is rotating all the time when the pole ear surface has aluminum chips, the pressing roller will not drivethe aluminum chips to move together, thereby avoiding scratch on the pole ear surface, preventing the pole ear from being damaged, and increasing the eligibility rate of the pole ear.

Description

technical field [0001] The invention relates to the field of lithium battery equipment, in particular to a battery tab processing equipment. Background technique [0002] The tab is the metal conductor that leads the positive and negative electrodes out of the battery. During the processing of the battery tabs, the shaping mechanism is first required to shape the battery tabs, and then the shaped battery tabs are sent to the cutting mechanism for cutting. However, the existing shaping mechanism adopts the method of scraping and pressing to shape the tab of the battery cell. After scraping, the surface of the tab of the battery cell will obviously have scratches, and when there are aluminum chips on the surface of the tab of the battery cell, After the scraping head of the shaping mechanism is scraped and pressed, the scraper drives the aluminum chips to move together, and scratches will be left on the battery tabs, which will damage the battery tabs and increase the defecti...
