Description

Technical Field

[0001] The utility model relates to the technical field of battery core processing, in particular to a battery core K value grading device. Background Art

[0002] Battery cells are divided into three types: aluminum shell battery cells, soft pack battery cells (also known as "polymer battery cells"), and cylindrical battery cells.

[0003] The K value will be marked on the battery cell during the battery cell formation stage. After the capacity division is completed, the battery cell will be encapsulated and then graded. That is, the battery cells with the same K value (which can be understood as the discharge speed) will be packed in the same area to facilitate the subsequent battery cell selection of modules and systems. Modules and systems select battery cells with the same K value for good consistency.

[0035] The battery cell transfer machine 2 is a robot;

[0036] The height of the placement frame 41 toward the inside of the track assembly 3 is relatively low, thereby preventing the battery cells from sliding out.

[0037] The track assembly 3 includes a support frame 31, a guide rail 32, two sprockets 33 and a chain 34. The support frame 31 is arranged in the middle of the battery cell transfer machine 2 and the second sorting area 5. The guide rail 32 is fixedly installed on the top of the support frame 31. The two sprockets 33 are respectively rotatably connected to the two ends of the inner side of the support frame 31, and the chain 34 is engaged with the outer side surfaces of the two sprockets 33.

[0038] The track assembly 3 is a ring track, and the guide rail 32 is also ring-shaped. A driving motor is installed at the bottom of one of the sprockets 33. When in use, it is used to drive the driving sprocket 33, thereby driving the chain 34 to move, and then the chain 34 drives the carrier assembly 41 to move.

When the carrier assembly 4 corresponds to the conveying track in the second sorting area 5 (the K value is set the same), the push plate set above the carrier assembly 4 will descend and push the battery cell to the conveying track of the second sorting area 5. The operator can directly take the battery cell at the tail end of the conveying track in the second sorting area 5 (put it into storage), which can improve production efficiency and reduce manual labor intensity.
