Then the material pressing cylinder 394 drives the nut mounting pressing block 395 to move upwards, at the moment, the pressure of the nut mounting pressing block 395 on the jig 5 disappears, the elastic force of the supporting spring 157 is released, and the upper jig block 151 and the lower jig block 152 reset. When the reset sensor 3918 senses the swaging sensor plate 397, it indicates that the swaging mounting block 395 has completely separated from the nut and the piercer on the fixture 15, and the fixture 15 can continue to move at this time. The cam bearing follower 186 capable of rolling is in contact with the supporting top plate 158, so that the friction force between the material supporting assembly 18 and the jig 15 can be reduced, and the jig 15 can move conveniently after material pressing is finished.

The jig 15 drives the puncture outfit and the nut to move to the sealing ring feeding device 4, and the sealing ring feeding device 4 is responsible for feeding the sealing ring and enabling the sealing ring to be sleeved on the puncture outfit. The jig 15 drives the puncture outfit, the nut and the sealing ring to move to the dropping funnel feeding device 5, and the dropping funnel feeding device 5 feeds the dropping funnel into the rotating sleeve 1533 of the jig 15. The jig 15 drives the puncture outfit, the nut, the sealing ring and the dropping funnel to move to the assembling device 6 to wait for assembling. The assembling device 6 drives the dropping funnel in the jig 15 to rotate, glue is coated in the puncture outfit end of the dropping funnel, and the dropping funnel rotates to enable the glue to be coated more uniformly. After the dropping funnel puncture outfit end is coated with a whole circle of glue, the assembling device 6 stops spraying the glue and drives the puncture outfit which is provided with the nut and the sealing ring on the jig 15 to move right above the dropping funnel, the assembling device 6 drives the puncture outfit to descend, the connecting end of the puncture outfit gradually enters the puncture outfit end of the dropping funnel until the puncture outfit step is inconsistent with the end of the dropping funnel, and the glue finishes the connection of the puncture outfit and the dropping funnel.

Then the jig 15 drives the assembled puncture outfit and the assembled dropping funnel to move to the visual detection device 65, and the visual detection device 65 detects and judges whether the assembly among the dropping funnel, the puncture outfit, the sealing ring and the nut is correct. When the system judges that the assembly among the dropping funnel, the puncture outfit, the sealing ring and the nut is incorrect, the jig 15 drives the defective product which is incorrect in assembly to move to a defective product blanking device 9 for blanking. When the system judges that the assembly among the dropping funnel, the puncture outfit, the sealing ring and the nut is correct, the jig 15 moves to the sheath feeding device 7, the sheath feeding device 7 feeds the sheath and enables the sheath to be sleeved on the puncture outfit, and the dropping funnel assembly is finished at the moment. The jig 15 drives the dropping funnel component to move to the finished product blanking device 8 for blanking.
