Description

Technical Field

[0001] The utility model relates to the technical field of tab positioning, and more specifically to a tab positioning mechanism for a lithium battery. Background Art

[0002] Tabs are an important part of lithium batteries. Lithium batteries used in new energy vehicles need tabs. Batteries are divided into positive and negative poles. Tabs are metal conductors that lead the positive and negative poles out of the battery core. Generally speaking, the tabs at the positive and negative poles of the battery are the contact points during charging and discharging. This contact point is not the copper sheet on the outside of the battery that we see, but a connection inside the battery.

[0003] During the production and processing of lithium batteries for new energy vehicles, it is necessary to position the lithium battery tabs and further conduct quality inspections on the lithium battery tabs to ensure that the positioned tabs can be used effectively and meet the standards.

[0004] The existing lithium battery tab positioning mechanism usually uses a clamp to clamp the lithium battery tab before proceeding to the next process. During the clamping process, it is easy to shake, the clamping becomes loose and falls off, or the clamping is too tight and damaged, resulting in poor positioning effect; in addition, the clamp is usually placed on a workbench or a machine tool operating table, which makes the device easy to shake, the installation is not firm enough, and it is difficult to fix it on the back plate or wall of the machine tool, making the installation and fixation of the device not flexible enough. In view of this, we propose a lithium battery tab positioning mechanism. Utility Model Content
