In the prior art, the lithium battery is a lithium battery. After it is just produced, it is charged once to activate the battery, which is similar to the formatting of a floppy disk. The battery can start normal charging and discharging after the formation is completed. At present, when the lithium batteries of the same batch are formed, it is impossible to form multiple lithium batteries at the same time, which will cause the formation efficiency of the lithium batteries of the same batch to be reduced and increase the workload. To solve this problem, the left fixed block 7 and the right fixed block 11 can be rotatably connected to the opposite sides thereof, and the top surfaces of the two lower support blocks 13 are provided with multiple batteries along the center. Hole 14, put the lithium battery to be formed into the battery hole 14 in advance, so that the bottom side of the lithium battery can be connected with the cathode terminal 15 at the bottom of the inner side of the battery hole 14, then start the first working motor 4 and the second working motor 8, prompting the first screw rod 5 and the second screw rod 9 to rotate, driving the first support block 6 and the second support block 10 to move downward, when the anode terminal 12 on the bottom side of the two moves to contact with the top surface of the lithium battery, the anode terminal 12 and the cathode terminal 15 can form the lithium battery at this time, thereby improving the formation efficiency.

[0021] A clamping frame 16 is fixed to the opposite sides of the multiple lower support blocks 13, and a rotating motor 17 is fixed to the side of the clamping frame 16. The bottom of the rotating motor 17 is rotatably connected to a lower support seat 18, and the bottom of the lower support seat 18 is fixedly connected to the top of the base plate 1, so that the lithium batteries after formation are realized.
