[0031] A loading mechanism is provided on the upper surface of the workbench 1;

[0032] Among them, the loading mechanism includes a fixed frame 2, the fixed frame 2 is fixedly connected to the right side of the upper surface of the workbench 1, the left side of the upper surface of the fixed frame 2 is fixedly connected to a loading clip 5, the lower surface of the fixed frame 2 is fixedly installed with a loading pneumatic cylinder 3, the right end of the loading pneumatic cylinder 3 is fixedly connected to a push plate 4, the left end of the push plate 4 passes through the fixed frame 2 and extends to the inside of the fixed frame 2, the outer surface of the push plate 4 and the inner surface of the fixed frame 2 are movably connected, and the operation of the loading pneumatic cylinder 3 causes the push plate 4 to push the material inside the loading clip 5 into the preset workstation 26.

[0033] The material to be riveted is placed inside the loading clip 5. When the loading pneumatic cylinder 3 is running, the push plate 4 will start to move to the left. During the movement of the push plate 4, the left end of the push plate 4 will push the material inside the loading clip 5, and finally the material will fall into the inside of the preset work station 26.

[0034] Among them, the left side of the upper surface of the workbench 1 is fixedly connected to the No. 1 mounting plate 6, the left side of the upper surface of the No. 1 mounting plate 6 is fixedly installed with a vibrating material tray 7, the right side of the upper surface of the No. 1 mounting plate 6 is fixedly connected to the No. 1 mounting frame 8, the upper surface of the No. 1 mounting plate 6 is fixedly installed with the No. 1 rotating motor 9 located between the No. 1 mounting plate 6 and the No. 1 mounting frame 8, the other end of the output shaft of the No. 1 rotating motor 9 is fixedly sleeved with the No. 1 rotating shaft 10, the outer surface of the No. 1 rotating shaft 10 is fixedly sleeved with a rotating plate 11 located inside the No. 1 mounting frame 8, and the outer surface of the rotating plate 11 and the inner surface of the No. 1 mounting frame 8 are movably connected.

[0035] When the No. 1 rotating motor 9 runs, the No. 1 rotating shaft 10 and the rotating plate 11 will start to rotate. Since four slots for placing rivet bolts are opened on the edge of the rotating plate 11, when the vibration tray 7 runs and starts to convey the rivet bolts, the rotation of the rotating plate 11 will cause the rivet bolts to be finally conveyed to the four slots of the rotating plate 11.

There are four electromagnets 33, and the four electromagnets 33 have the same size.

[0037] The electromagnet 33 can absorb the rivet bolt after being energized. The design of the translational pneumatic cylinder 13 allows the second mounting plate 15 to move left and right, while the design of the upper and lower pneumatic cylinders 14 allows the second mounting plate 15 to move up and down.

[0038] The upper surface of the workbench 1 is fixedly connected to a No. 3 mounting frame 16 located below the turntable 25 , and a laser ranging sensor 17 is fixedly mounted on the outer surface of the No. 3 mounting frame 16 .

[0039] The laser distance sensor 17 can measure the length of the rivet bolt, and the output end of the laser distance sensor 17 is electrically connected to the input ends of the feeding pneumatic cylinder 3, the gas-liquid booster cylinder 19 and the rotating pneumatic cylinder 30 respectively.

[0040] Among them, the upper surface of the workbench 1 is fixedly connected to the No. 4 mounting frame 18 located on the right side of the No. 3 mounting frame 16, and the upper surface of the No. 4 mounting frame 18 is fixedly installed with a gas-liquid booster cylinder 19. The bottom end of the gas-liquid booster cylinder 19 passes through the No. 4 mounting frame 18 and is fixedly connected to the pressure block 20 located above the turntable 25.

[0041] The operation of the gas-liquid booster cylinder 19 causes the pressing block 20 to move up and down.

[0044] Among them, the upper surface of the workbench 1 is fixedly connected to a pushing pneumatic cylinder 27, the top of the pushing pneumatic cylinder 27 is fixedly connected to a pushing plate 28, the upper surface of the pushing plate 28 is fixedly connected to a pushing rod 29 located below the turntable 25, the number of the pushing rods 29 is four, and the four pushing rods 29 have the same size, the upper surface of the workbench 1 is fixedly connected to a rotating pneumatic cylinder 30 located in front of the pushing pneumatic cylinder 27, and the top of the rotating pneumatic cylinder 30 is fixedly connected to a unloading tray 31.

[0045] When the ejecting pneumatic cylinder 27 is in operation, the ejecting rod 29 will eject the material located inside the preset work station 26 .

[0046] The working principle and use process of this utility model:

[0047] First, when the workbench 1 starts to run as a whole, the vibrating material tray 7 will start to transport the rivet bolts. Due to the operation of the No. 1 rotating motor 9, the No. 1 rotating shaft 10 and the rotating plate 11 will start to rotate. Eventually, these rivet bolts will be inserted into the four slots of the rotating plate 11 as the rotating plate 11 rotates. At this time, the translation pneumatic cylinder 13 and the upper and lower pneumatic cylinders 14 will start to run, so that the No. 2 mounting plate 15 moves to the top of the rotating plate 11 and makes the electromagnet 33 contact the rivet bolts in the slot of the rotating plate 11. At this time, the electromagnet 33 will start to energize, and these rivet bolts will be attracted by the magnetic force of the electromagnet 33. Then the No. 2 mounting plate 15 as a whole will be reset under the operation of the translation pneumatic cylinder 13 and the upper and lower pneumatic cylinders 14.

[0048] At this time, the loading pneumatic cylinder 3 will start to run and make the push plate 4 push the material inside the loading clip 5 into the preset station 26. Due to the operation of the No. 2 rotating motor 23, the No. 2 rotating shaft 24, the turntable 25 and the preset station 26 will start to rotate. When the preset station 26 with the material moves to the bottom of the No. 2 mounting plate 15, the upper and lower pneumatic cylinders 14 will run again. At this time, the rivet bolt under the electromagnet 33 will be inserted into the riveting hole of the material. Then the electromagnet 33 is powered off, and the upper and lower pneumatic cylinders 14 run again, so that the No. 2 mounting plate 15 is reset again.

[0049] At this time, the turntable 25 rotates again, so that the preset station 26 with the material moves to the top of the laser distance sensor 17. At this time, the laser distance sensor 17 will start to run and measure the length of the rivet bolt. When the rivet bolt measurement meets the standard, the turntable 25 will start to rotate, so that the preset station 26 with the material moves to the bottom of the pressure block 20, and then the gas-liquid booster cylinder 19 will start to run. At this time, the pressure block 20 will start to press down and rivet the rivet bolt on the material. During this process, the pressure sensor 22 will detect the riveting force received during this process.

[0050] After the riveting is completed, the turntable 25 rotates again, so that the preset station 26 with the riveted material moves to the top of the ejector rod 29, and then the operation of the ejector pneumatic cylinder 27 will cause the ejector plate 28 and the ejector rod 29 to move upward, and finally the ejector rod 29 will lift the riveted material inside the preset station 26, and then the rotating pneumatic cylinder 30 will start to operate, and finally the unloading tray 31 will push the material down from above the ejector rod 29, thereby completing the fully automatic riveting of the material.
