Abstract

The invention relates to a high control device for the ear glue of a soft-packed lithium battery, including a pressure plate, a scraper, a pressure plate driving device, a scraper driving device and a laser, a pressure plate driving device, a scraper driving device and a laser connection control device, and the laser is used for Hot-melt pole ear glue; two height-adjustable positioning rods are installed vertically on the pressure plate. The two positioning rods are distributed on both sides of the pressure plate and extend downward in the vertical direction. The pressure plate driving device can drive the pressure plate to squeeze the pole downward. Ear glue, the scraper driving device can drive the scraper to move in the horizontal direction to scrape glue; the present invention also provides a method for controlling the height of the ear glue on the basis of the above device. The beneficial effect of the invention is that the operation is flexible, the height of the ear glue can be effectively controlled, the product quality can be guaranteed, and the production cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing, in particular to a device and method for controlling the tab height of a soft-pack lithium battery. Background technique [0002] Lithium batteries are widely used in mobile and portable consumer products because of their advantages of high energy density and good safety performance. In particular, soft-pack lithium batteries have been widely used in mobile devices due to their advantages such as light weight and changeable shape. At present, the packaging of soft-packed lithium batteries is to weld the pole piece with a certain ear glue height and then wind it into a core. The core is packaged into the aluminum-plastic film shell. The aluminum-plastic film is hot-melt bonded, which requires strict control of the height of the ear glue, otherwise the ear glue is not exposed or exposed too much, which will easily cause poor sealing, short circuit of the edge sealing, battery...
