A power battery pole lug encapsulation device and encapsulation method thereof

Abstract

The invention discloses a power battery lug wrapping device, which comprises a wrapping driver, a guide table, and an indenter for pushing the adhesive tape. The channel through which the tabs pass, the direction of the channel is perpendicular to the movement direction of the indenter, and the guide table is provided with a front limit block and a rear limit block on the entrance side of the channel, and the front limit block and the rear limit block are located at On both sides of the width of the channel, the front limit block and the rear limit block are slopes at the entrance of the channel, and the bottom of the slope is lower than the channel, and a baffle is arranged above the channel, and the baffle is located between the front limit block and the channel Between and adjacent to the rear limiting blocks, an air blowing hole is arranged in the center of the guide platform, and the invention also discloses a rubber encapsulation method using the device. The invention has the advantages of realizing the lamination of tabs with glue, the tape is firmer, and it is not easy to open the glue when the electrolyte is injected into the battery, avoiding the short circuit of the battery tabs caused by the opening of the glue, and reducing production loss.

Description

technical field [0001] The invention relates to an automatic production device for a power battery, in particular to a battery lug wrapping device and a wrapping method thereof. Background technique [0002] In order to prevent the tabs of the battery from short-circuiting, before the tabs are welded, the exposed parts of the tabs are covered with glue in advance. However, there are still some deficiencies in the existing battery lug automatic overmolding device, which hinders the development of the industry. At present, there are also some patents about the tab rubber, such as a tab rubber coating device (country: China, publication number: CN103474612A, publication date: 2013-12-25), which discloses the use of a workbench to drive the first push block, The second push block rises, so that the adhesive paper attached to the tab changes from a horizontal state to a vertical state. When the bottom of the first push block and the bottom of the second push block move to the sa...

However, there are still some deficiencies in the existing battery tab automatic rubber-covering molding device, which hinders the development of the industry.

At present, there are also some patents on the tab rubber, such as a tab tab device (country: China, publication number: CN103474612A, publication date: 2013-12-25), which discloses the use of a workbench to drive the first push block, The second push block rises, so that the adhesive paper attached to the tab changes from a horizontal state to a vertical state. When the bottom of the first push block and the bottom of the second push block move to the same height as the tab, the first push block The block and the second push block press the tape respectively and move towards the middle of the workbench, so that the tape is covered on the tab. This device improves the production efficiency, but because the tape on both sides is only covered on the upper surface of the tab respectively, The tape is easy to unglue, and at the same time, the method of encapsulation is not smooth enough, the quality and appearance of the finished battery produced are not ideal, and the device is more complicated
