Description

Technical Field

[0001] This utility model relates to the field of lithium battery production, specifically to an automatic sorting machine for finished lithium batteries. Background Technology

[0002] Lithium-ion batteries are rechargeable batteries that primarily function by the movement of lithium ions between the positive and negative electrodes. During charging and discharging, Li+ ions repeatedly insert and extract between the two electrodes: during charging, Li+ ions extract from the positive electrode, pass through the electrolyte, and insert into the negative electrode, leaving the negative electrode in a lithium-rich state; the reverse occurs during discharging. In existing technologies, lithium batteries require inspection after production before packaging. Current inspection methods typically rely on manual inspection, which is slow, inconvenient, and labor-intensive. Therefore, those skilled in the art have proposed an automatic sorting machine for finished lithium batteries to address the problems mentioned in the background section. Utility Model Content

Threaded sleeves 19 are symmetrically fitted onto the outer surface of the threaded rod 17. A connecting plate 20 is installed on the side of the threaded sleeve 19, and the connecting plate 20 is electrically connected to the detection body 15 via a wire harness. A lifting plate 22 is provided on the side of the connecting plate 20. Several L-shaped tubes 21 are installed inside the lifting plate 22. Detection electrode plates 23 are installed at the lower end of the L-shaped tubes 21, and wires are installed at one end of the detection electrode plates 23. The wires pass through the L-shaped tubes 21 and are electrically connected to the connecting plate 20. The rejection mechanism 24 includes a rejection frame 25 and a fixing plate 26.

According to the position of the unqualified lithium batteries, the corresponding electric telescopic rod 27 is controlled to work. The electric telescopic rod 27 drives the push block 28 to descend and push the lithium battery. The lithium battery is pushed down in the placement hole 8 by the pushing force and pushes the tray 9.

The lithium battery falls down due to gravity. The unqualified lithium battery falls into the rejection frame 25.

[0025] Then, motor 5 continues to drive the placement plate 7 to rotate intermittently, so that the placement plate 7, after rejecting the unqualified lithium batteries, moves to the position of the collection mechanism 29.
