In this embodiment, the driving belt 42 is connected to the supporting platform 41 through the connecting plate 48 and the connecting block 481, so that the power output by the motor 44 can be stably transmitted to the supporting platform 41.

The implementation principle of assembly production line is filled to gas cylinder in this application embodiment is: during the use, place gas cylinder 1 inside holding a section of thick bamboo 45 to will hold a section of thick bamboo 45 and place on plummer 41, make and hold inside a section of thick bamboo 452 of 45 bottoms pegs graft the positioning hole 411 on plummer 41, make and hold a section of thick bamboo 45 and can stably place on plummer 41, and follow plummer 41 and remove. When a cylinder 45 containing a gas-filled bottle 1 is moved to the installation space between the component 2 screwing the gas charging nozzle and the component 3 screwing the bottle nozzle, a piston rod of the cylinder 7 extends out and is plugged inside the positioning cylinder 452, the cylinder 45 is jacked up, when the gas bottle nozzle 111 is close to the bottle nozzle locking piece 35, the power output by the driving piece 33 is transmitted to the bottle nozzle locking piece 35 through the second transmission component 31, the bottle nozzle locking piece 35 swings left and right, and the gas bottle nozzle 111 is inserted into a locking cavity 352 formed in the bottle nozzle locking piece 35 through swinging. After the cylinder nozzle 111 is inserted into the locking cavity 352, the cylinder nozzle 111 is driven to rotate by the driving member 33 until the conical plug 113 no longer blocks the air charging opening 122, and then the power output of the driving member 33 is stopped and the brake is applied. Because the plurality of locking blocks 353 are fixedly arranged in the locking cavity 352, the gas cylinder nozzle 111 is locked by the locking blocks 353 to a state difficult to rotate, and meanwhile, the gas cylinder nozzle 111 is directly abutted to the inflating nozzle 24. At this time, the power output by the power member 23 is transmitted to the charging connector 24 through the first transmission assembly 21, so as to drive the charging connector 24 to rotate, and the charging connector 24 is in threaded connection with the gas bottle nozzle 111, so that the gas can be charged conveniently. It should be noted that, while the power member 23 outputs power, the driving member 33 is always braked, and at this time, the air charging connector 24 is communicated with the interior of the bottle body 12 through the air passage 1111 and the air charging port 122, so as to start charging air into the air bottle.

After the inflation is completed, the user can rotate the gas cylinder nozzle 111 to make the gas cylinder nozzle 111 press the conical plug 113 to approach the inflation inlet 122, and finally the conical plug 113 abuts against the inner wall of the inflation inlet 122 to seal the inflation bottle 1. Then, the charging connector 24 is rotated to be separated from the threaded connection state with the gas cylinder connector 111, and then the piston rod of the cylinder 7 is retracted, so that the gas cylinder and the accommodating cylinder 45 automatically fall onto the bearing platform 41 along with the piston rod of the cylinder 7 under the action of gravity, and finally, the complete charging process of the gas charging bottle 1 is realized.

In the process of sealing the air inflation bottle 1, in order to make the process more stable, the thread direction of the air bottle nozzle 111 locked on the mounting nozzle 112 can be set to be a structure opposite to the locking direction of the air inflation nozzle 24, so that when the air bottle nozzle 111 is locked in a rotating mode, the air bottle nozzle 111 is also locked relative to the air inflation nozzle 24, and the possibility that air escapes through the gap between the air bottle nozzle 111 and the air inflation nozzle 24 when the air bottle nozzle 111 is locked on the mounting nozzle 112 can be reduced. Meanwhile, by observing the torque sensors disposed on the first servo motor as the power member 23 and the second servo motor as the driving member 33, the user can know more conveniently when the locking state between the charging nozzle 24 and the gas cylinder nozzle 111 is reached, and can also know more conveniently when the locking state between the gas cylinder nozzle 111 and the mounting nozzle 112 is reached, thereby facilitating the user to control a single step in the charging process.

In addition, in the process of threaded connection between the charging connector 24 and the gas cylinder connector 111, the charging connector 24 needs a displacement amount in the vertical direction, so that the support frame 22 can be moved in the vertical direction through the charging compensation cylinder 27 to compensate for the displacement of the charging connector 24 in the vertical direction, and certainly, due to the arrangement of the charging assembly compensation spring 28 and the gas cylinder assembly compensation spring 34, the gas cylinder 7 can directly drive the accommodating cylinder 45 to move in the vertical direction to compensate for the displacement of the charging connector 24 in the vertical direction.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
