[0001] The utility model relates to the technical field of battery positioning, in particular to a positioning mechanism for simultaneously positioning a battery core and a pole ear. Background Art

[0002] In the production process of soft-package batteries, one of the workstations needs to position the battery cells and tabs in order to complete subsequent processes, such as OCV testing. The detection probe needs to contact the tabs of the battery cells. Therefore, the battery cells to be tested need to be positioned to prevent displacement during testing. At the same time, the tabs also need to be fixed to prevent the detection probe from damaging the tabs or failing to align with the tabs.

[0003] There are many mechanisms in the prior art that can clamp battery cells and tabs, but most of them are for clamping batteries of the same model. If batteries of different models need to be clamped, the clamp needs to be replaced, which has low applicability and cannot match multiple models of batteries, resulting in low production efficiency.

[0004] Therefore, there is an urgent need for a positioning mechanism that can simultaneously position the battery cell and the tab to solve the above problems. Utility Model Content
