Description

Technical Field

[0001] The utility model relates to the technical field of polymer battery production, in particular to a polymer battery core positioning mechanism. Background Art

[0002] Polymer battery cells are also a component of lithium-ion batteries. The battery cell is the power storage part of the rechargeable battery after the protection circuit board is removed. The quality of the battery cell directly determines the quality of the rechargeable battery. When welding and other operations are performed on the surface of the polymer battery cell, it will be fixed by a positioning mechanism.

[0003] The existing polymer battery cell positioning mechanism is usually achieved by arranging telescopic cylinders on both sides of the polymer battery cell. The output end is extended by the telescopic cylinder, and the clamping blocks on both sides are pushed closer to each other to position and clamp the polymer battery cell. However, with use, the accuracy of the telescopic length of the output end of the telescopic cylinder decreases, resulting in less force of the clamping blocks squeezing each other, causing the polymer battery cell to loosen during positioning, or the force of the two clamping blocks is too great, causing the two ends of the polymer battery cell to be squeezed and deformed, causing damage to the polymer battery cell.
