Embodiment
As shown in Figure 1, Figure 2 and Figure 3, flexible package lithium cell battery formation clamp of the present utility model is that a kind of bluetooth lithium ion battery changes into aging integrated machine clamp, and it comprises pallet 1, battery folder 2, pcb board 3 and probe 4.
Battery folder 2 is arranged on pallet 1, and pallet 1 can adopt fibre resin hard material to be processed into, and pallet 1 carries pressure during Battery formation, facilitates battery to have enough to meet the need.The pallet 1 of the present embodiment is provided with the battery folder 2 that 4 lay respectively at pallet 1 four angles, on pallet 1, correspondence is provided with battery and places position a, and lithium battery 10 is positioned over battery and places on a of position.Battery folder 2 for clamping the positive and negative lug of lithium battery, to prevent when upper and lower battery because loose contact causes short circuit.The bottom surface of pallet 1 is provided with 4 pcb boards 3, and every a slice pcb board 3 is all connected with a battery folder 2 by wire.Probe 4 is arranged on the heating plate 20 of formation device, and when pallet is positioned on heating plate, pcb board 3 and probe 4 form electrical contact.
Conveniently take pallet, prevent temperature too high scald one's hand, pallet 1 can also arrange handle 1-1.The battery folder 2 of the present embodiment is installed on pallet 1 by threaded fastener, pallet 1 is processed with the waist-shaped hole b installing battery folder 2, threaded fastener coordinates with waist-shaped hole, and the position that battery folder 2 is arranged on pallet 1 is adjustable, to adapt to the Bluetooth battery of various sizes.Pcb board 3 is also fixed on pallet 1 bottom surface by threaded fastener.
