The weighing plate 810 is slidably connected to the inner side of the slot 802. The outer wall of the bottom end of the spring relay block 804 is not in contact with the pressure sensor 808.

[0023] The device starts the right manipulator 4 to grab the spare tank on the right conveyor belt 1 through the clamp 5, and then places it on the weighing plate 810, so that the spare tank squeezes the weighing plate 810 and squeezes the spring relay block 804 through the weighing plate 810, so that the spring relay block 804 squeezes the gas in the gas collecting cylinder 803 when under pressure, thereby changing the internal pressure of the gas collecting cylinder 803, and detecting the pressure through the pressure sensor 808 installed inside the gas collecting cylinder 803. When the predetermined value is reached, the discharge valve of the discharge barrel 6 is closed to complete the quantitative filling, and the left manipulator 4 is started to grab the spare tank on the left conveyor belt 1 through the clamp 5, and place it on the left conveyor belt 1 for transportation.
