Embodiment Construction

[0047] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many other different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0048] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for pur...

Abstract

The invention discloses a tab welding device and battery cell production equipment. The tab welding device is characterized by comprising a cutting mechanism, a normalizing mechanism, a transferring mechanism, a conveying mechanism and a welding mechanism, and a tab material belt is conveyed to the normalizing mechanism through the cutting mechanism. The tab material belt before cutting is positioned and flattened through the normalizing mechanism, the flatness and the cutting precision of a tab are improved, then the welding precision is guaranteed, a clamping part and an avoiding part are arranged on a gripper of the transferring mechanism, the clamping part is used for clamping the tab, the avoiding part is used for avoiding the tab material belt, in the process that the gripper clamps the tab and transfers the tab to the conveying mechanism through the driving assembly, the tab material belt can penetrate through the avoiding part to be conveyed to the normalizing mechanism, that is, the tab material belt can be positioned and flattened while the cut tab is transferred, the production speed is increased, and the welding efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery manufacturing equipment, in particular to a tab welding device and battery production equipment. Background technique [0002] The tab is a raw material of the lithium-ion polymer battery. It is a metal conductor drawn from the positive and negative poles of the battery. Generally speaking, it is the ear of the positive and negative poles of the battery, which is the contact point when the battery is charging and discharging. In the existing process, the tab is usually welded to the pole piece by a welding device, and then the pole piece and the diaphragm are wound into a battery core by a winding machine. [0003] During the tab welding process, the existing welding device has low precision and slow speed when cutting and transporting the tabs, resulting in the welding speed and welding accuracy of the tabs not keeping up with the production demand. Contents of the invention [0004] T...
