Embodiment Construction

[0041] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0042]It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to another component or there may be an intervening component at the same time. When a component is considered to be "set on" another component, it may be located directly on the other component or may co-exist with an intervening component. The terms "top," "bottom," "top," "bottom," "left," "right," "front," "back," and similar expressions are used herein for illustrative purposes only.

[0043] The term "perpendicular" is used to describe the ideal state between two components. In the actual state of production or use, there may be an ap...

Abstract

The invention discloses a pole lug forming device and a pole lug forming method. The pole lug forming device comprises a first template, a second template, a first conversion head, a second conversion head, a glue injection part and a sealing cover part. The first template is provided with a first runner, one side, facing the first template, of the second template is provided with a second runner, the first adapter is connected with the first template, and the second adapter is connected with the second template. The first template is configured to be capable of moving relative to the sealing cover piece so as to be connected with the sealing cover piece or the second template. And when the first template is connected with the cover sealing piece, the cover sealing piece seals the first runner, and the glue injection piece injects glue into the first runner through the first conversion head, so that the first time of glue injection is completed. And when the first mold plate is connected with the second mold plate, the first runner is communicated with the second runner, and the glue injection piece injects glue into the second runner through the second conversion head, so that secondary glue injection is completed. The tab glue is formed in an injection molding manner, so that the sealing performance of the tab part of the battery is improved.

Description

technical field [0001] The present application relates to the technical field of energy storage, and in particular, to a tab forming device and a tab forming method. Background technique [0002] An important process in the production and manufacturing process of lithium-ion batteries is welding the tabs. The battery draws electricity out of the tabs to generate a circuit, and the production of battery tabs is an independent process. The tabs include metal tabs that can conduct electricity. the tab and the tab glue on the tab tab. [0003] The current pole ear production process is to stick two pieces of pole ear glue on the upper and lower sides of the pole ear piece by hot pressing, so that the upper and lower layers of the pole ear glue and the pole ear piece form a whole. The existing tab production process is difficult to overcome the problem that there is a passage between the upper and lower layers of tab glue and the tab sheet, and the passage extends along the exte...
