In the process that the first layer plates 331 and the second layer plates 332 move away from each other, the two guide members 32 arranged side by side can support the movement of the first layer plates 331 and the second layer plates 332. In the process that the first layer plates 331 and the second layer plates 332 move away from each other, one end and the other end of the first layer plate 331 will respectively extrude the corresponding first elastic member 322 and one end and the other end of the second layer plate 332 will respectively extrude the corresponding second elastic member 323, so that the first elastic member 322 and the second elastic member 323 are compressed. The second layer plate 332 of the last layer plate assembly 33 will extrude the pressure sensor 35, and the extrusion force is the pressure of the lithium battery 200, so that the pressure of the lithium battery 200 can be detected through the pressure sensor 35. Different pressures of compressed air are filled into the air bags 333, so that different types of lithium batteries 200 can be adapted, and the application range is wide.When the lithium battery 200 is subjected to formation processing, the lithium battery 200 will expand due to heat generated during the formation process, thus the pressure on the lithium battery 200 will continuously increase. When the pressure on the lithium battery 200 detected by the pressure sensor 35 exceeds a predetermined value, the air bag 333 is deflated by the air charging and discharging device through the air bag joint 3331 of the air bag 333, so that the air bag 333 is reduced. At this time, under the resetting action of the first elastic member 322 and the second elastic member 323, the first layer plate 331 and the second layer plate 332 of the corresponding layer plate assembly 33 can be driven to move close to each other, that is, to move towards each other. In this way, the extrusion force of the lithium battery 200 in the corresponding restraint space 38 by the second layer plate 332 of the previous layer plate assembly 33 and the first layer plate 331 of the next layer plate assembly 33 can be reduced, until the pressure on the lithium battery 200 reaches the predetermined value. In this way, the pressure on the lithium battery 200 can be adjusted, and the constant pressure on the lithium battery 200 during the formation process can be ensured, so that the charging and discharging of the lithium battery 200 is uniform, and the performance of the lithium battery 200 is improved. After the formation is completed, the air bag 333 is deflated by the air charging and discharging device, and at this time, under the resetting action of the first elastic member 322 and the second elastic member 323, the first layer plate 331 and the second layer plate 332 of the corresponding layer plate assembly 33 can be driven to move close to each other to return to the initial position. In this way, the lithium battery 200 can be released from the restraint.

As the first and second layers 331, 332 of the layer assembly 33 move away from each other, the first layer 331 can drive the fastener 337 and the mounting sleeve 336 to move synchronously. When the protrusion 3361 abuts the bottom of the fourth mounting groove 332c, the distance between the first and second layers 331, 332 is at its maximum.

After the formation is completed and the lithium battery 200 is released, the positive electrode power taking probe 93 and the negative electrode power taking probe 94 are first driven to move upwards by the driving assembly, so that the head of the positive electrode power taking probe 93 is separated from the positive copper bar 95 and the head of the negative electrode power taking probe 94 is separated from the negative copper bar 96.
