At this time, the upper end of the battery air bag that has been vacuum-conditioned will be located between the two sealing clamps 27, and then the air in the sealing frame Ⅱ 24 will be discharged through the vacuum pump Ⅱ 25, and then the two sealing clamps 27 will be driven by the control cylinder Ⅰ 26. By moving toward the side close to each other, the two sealing clamps 27 can clamp the upper end of the battery air bag after the vacuum standing treatment, and the heating tube 28 can be controlled to heat the upper end of the battery air bag after the vacuum standing treatment to perform preliminary sealing, and then the two sealing clamps 27 are driven by the control cylinder Ⅰ26 to move away from each other to release the upper end of the battery air bag, and then the air can be sent back to the sealing frame Ⅱ24 through the vacuum pump Ⅱ25, and then the telescopic rod of the lifting cylinder Ⅱ22 is controlled to shorten, so that the lifting frame 13 at the rear side can move downward and reset due to gravity, and the lifting cylinder Ⅱ23 can drive the sealing frame Ⅱ24 to move upward and reset, so that the bottom surface of the sealing frame Ⅱ24 is separated from the top surface of the lifting frame 13 at the rear side, so that the battery air bag can be automatically sealed. Vacuum pre-sealing treatment; then the turntable 12 is driven by the driving motor 11 to rotate 90 degrees, which can drive the battery air bag that has been vacuum pre-sealed to rotate to the right side of the liquid injection machine, and then the sliding frame 33 is controlled to move downward by the moving cylinder Ⅱ 34, which can drive the moving fixture 35 to move downward and align with the upper end of the battery air bag that has been vacuum pre-sealed, and then the two moving fixtures 35 are driven to move to the side close to each other by the control cylinder Ⅱ 36, so that the two moving fixtures 35 can clamp the upper end of the battery air bag, and then the push block Ⅱ 39 is driven to move forward by the electric push rod Ⅳ 38. When the push block Ⅱ 39 contacts the sliding fixture 142 on the right side, the push block Ⅰ 17 can push the sliding fixture 142 to move forward, and the reset spring 143 is compressed to make the sliding fixture 142 move forward. The movable clamp 142 releases the battery air bag, and then the sliding frame 33 is controlled to move upward and reset through the movable cylinder II 34. The sliding frame 33 can clamp the battery air bag through the movable clamp 35 and move upward to separate from the sliding clamp 142 on the right side. Then the sliding frame 33 is driven to move rightward through the movable cylinder I 32. The sliding frame 33 can clamp the battery air bag through the movable clamp 35 and move rightward to the top of the conveyor 29. Then, through the action of the movable cylinder II 34 and the control cylinder II 36, the movable clamp 35 can clamp the battery air bag and move downward, and the battery air bag is placed on the conveyor 29 and released. Finally, the sealed battery air bag can be transported backward for processing through the conveyor 29. This reciprocating process can automatically inject liquid into the battery air bag. ;
