[0032] The packaging component 3 is arranged on the bottom surface of the thermal insulation component 2 .

[0033] The middle connecting plate 202 is driven by the driving part 101 to move. Since the upper connecting part 102 is slidably connected to the lower connecting part 201, the middle connecting plate will not shake and can move up and down smoothly, thereby driving the packaging component 3 to move, and then the packaging component 3 can package the battery. At the same time, the driving end of the driving part 101 is provided with a sensor part for detecting torque. By setting parameters for the driving part 101, the required pressure value is achieved, and then the packaging time is delayed. It can make the adjustment more convenient and quick, and different pressure values ​​can be quickly adjusted in the product of different sizes. After the packaging is completed, the driving part 101 makes the packaging component 3 rise to complete the packaging.

Since the slider body 1021 is slidably connected to the slide rail 2011, the guide rod 2012 also plays a role of limiting and guiding. Therefore, the middle connecting plate will not shake and can move up and down smoothly, thereby driving the packaging component 3 to move, and then the packaging component 3 packages the battery. At the same time, the driving end of the driving part 101 is provided with a pressure sensor 106 for detecting torque. By setting parameters for the motor 1011, the required pressure value is achieved, and then the packaging time is delayed. The adjustment can be more convenient and quick, and different pressure values ​​can be quickly adjusted in the size change product. After the packaging is completed, the motor 1011 causes the packaging component 3 to rise to complete the packaging.
