Thus, the gaskets 1034 are pushed out of the material bin 1031 one by one by the feeding push rod 1032. When taking materials, the feeding push rod 1032 pushes out the gaskets 1034 to be installed, and the feeding slide 1033 places the pushed gaskets 1034 in the material taking trough, and the movement of the feeding slide 1033 drives the gaskets 1034 to move until they are at the corresponding position of the material taking position 1024 of the push plate 1023, so that when the push plate 1023 is close to the feeding mechanism, the gasket taking and placing mechanism at the material taking position 1024 takes the gaskets 1034 in the material taking trough.

[0039] The push plate 1023 is also provided with a detection position 1025, at which a sensor for detecting whether there is a gasket in the joint is provided, and the sensor may be a laser or other type of sensor. The push plate 1023 is also provided with a dust cleaning position 1027, at which a cleaning device for cleaning the gasket installation position of the joint is provided, and the cleaning device may be a mechanism capable of blowing air.

[0040] It also includes a recovery bin 104, which is used to accommodate the gasket 1034 removed from the gas cylinder by the recovery position 1026.

[0041] When installing the gasket 1034, the gasket pick-up and placement mechanism at the material taking position 1024 takes the gasket 1034 to be installed at the feeding mechanism, and the gasket sliding mechanism drives the push plate 1023 to the joint. The sensor at the detection position 1025 detects whether there is a gasket 1034 in the joint to be installed. If there is, the gasket pick-up and placement mechanism at the recycling position 1026 takes out the old gasket, and the push plate 1023 moves to the recycling bin 104 to throw the old gasket into the recycling bin 104. The cleaning device at the dust cleaning position blows and cleans the gasket installation position to prevent large particles from entering the joint. After that, the gasket pick-up and placement mechanism at the material taking position 1024 places the gasket 1034 in the gasket installation position of the joint to complete the installation of the gasket 1034.

[0042] The valve opening and closing device comprises a valve opening clamping jaw 121, and the valve opening clamping jaw 121 is used to open the valve opening of the gas cylinder 20. The valve opening clamping jaw 121 can open the valve of the gas cylinder 20 by rotating.

[0043] The cylinder connection process includes the following steps: 1. Place the gas cylinder 20 to be connected into the housing 3, place it on the turntable 115, and clamp and fix the gas cylinder 20 with the clamping roller; 2. The rotating lifting device drives the gas cylinder 20 to the plug removal height position, and the turntable 115 drives the gas cylinder 20 to rotate until the plug and the plug connection seat 735 are collinear, and the plug is removed by the plug removal device; 3. The gasket installation device installs the gasket 1034 into the joint to be connected; 4. The rotating jacking device drives the gas cylinder 20 to the joint installation height position, and the turntable 115 drives the gas cylinder 20 to rotate until the joint and the central axis of the joint connection seat 833 are in line, and the joint is installed by the joint disassembly device; 5. The valve port clamping claw 121 of the valve port switch device 12 opens the valve port of the gas cylinder 20, so that the gas in the gas cylinder 20 enters the gas pipeline valve disc 9 through the joint disassembly device; if the gas pipeline valve disc 9 detects that the gas pressure in the gas cylinder 20 is too low or the falling speed is too fast, it indicates that there is a leak at the connection position, and timely alarm, gas extraction and ventilation operations are performed; 6. After one of the gas cylinders in the housing 3 has completed gas supply, the gas pipeline valve disc 9 switches the passage to allow another gas to be supplied to ensure the continuity of gas supply. Before gas supply, repeat step 5 to perform leakage detection.

[0044] The present invention is described above by way of examples, but the present invention is not limited to the above specific embodiments, and any changes or modifications made based on the present invention belong to the scope of protection claimed by the present invention.
