Description

Technical Field

[0001] This utility model relates to the field of battery cell processing technology, and in particular to a battery cell sorting device. Background Technology

[0002] After the battery cells are processed, they need to be inspected and sorted. A single battery pack typically consists of dozens or even hundreds of cells connected in series or parallel. Significant differences in cell capacity, voltage, internal resistance, and other parameters can lead to the "weakest link" effect (the worst-performing cell will drag down the entire battery pack's range and cycle life, and may even cause overcharging and over-discharging, shortening its overall lifespan). Even cells produced in the same batch may have variations in capacity, voltage, and internal resistance. Sorting can group cells with similar parameters together, improving battery pack consistency. Current battery sorting primarily relies on manual inspection using testing fixtures, which is inefficient. Furthermore, since cell sorting involves further categorizing cells into multiple batches within a single batch, it is cumbersome, and workers are prone to fatigue and errors over long periods. Therefore, we need automated equipment to perform cell inspection and multi-batch sorting. Utility Model Content

The sorting machine platform is provided with multiple sets of second conveying mechanisms corresponding to receiving battery cells from the second sorting mechanism.

[0005] Battery cells are loaded onto trays by a feeding device. A sorting device uses a detection mechanism and a barcode scanner to check the internal resistance and voltage of the cells and marks them accordingly for subsequent sorting. The first sorting mechanism sorts qualified cells and conveys them to a first conveyor mechanism. A flipping mechanism then transfers the cells from the first conveyor mechanism to a boxing device for boxing.

A transfer mechanism handles the cells during the electric travel process. Through an automated production process, the cells are systematically detected, marked, and sorted through multiple steps. This step-by-step process effectively avoids sorting errors, ensuring accurate and reliable sorting with high production efficiency, providing a precise and effective guarantee for battery cell sorting.
