[0061] The specific workflow is as follows:

[0062] The O-ring to be expanded is fed into the distribution trough 3 through the feeding assembly 1 (linear vibrating plate feeder). The distribution cylinder 2 drives the distribution push rod 4 to push the O-ring to be expanded to the material collection point 5.

[0063] By cooperating with the horizontal drive cylinder 17 and the vertical drive cylinder 22, the position of the material taking mechanism is adjusted so that the first material taking column 71 is lowered and inserted into the material taking point 5, and the O-ring to be expanded is taken onto the first material taking column 71;

[0064] The horizontal driving cylinder 17 and the vertical driving cylinder 22 are used to cooperate with each other again to adjust the position of the material taking mechanism, and the first material taking column 71 with the O-ring is moved to above the diameter expansion column 12 and the diameter expansion part 121, and then the first material taking column 71 is lowered to make the truncated cone-shaped end of the first material taking column 71 dock with the diameter expansion part 121, and then the pushing cylinder 9 is started to drive the pushing plate 10 and the pushing member 72 to descend, and the O-ring is pushed out from the first material taking column 71 and sleeved on the diameter expansion part 121, and the pushing is continued to make the O-ring gradually expand under the effect of the size of the truncated cone-shaped diameter expansion part 121, thereby realizing the diameter expansion of the O-ring; in this process After the first material feeding column 71 is emptied, the pushing member 72 is pushed downward along the outer wall of the first material feeding column 71 by the pushing cylinder 9 and the pushing plate 10, and the O-ring on the first material feeding column 71 is pushed out by the action of the stopper 722, and then the pushing member 72 gradually slides downward to the expanded diameter portion 121. As the outer diameter of the contact surface with the truncated cone-shaped expanded diameter portion 121 gradually increases, the stopper 722 will also slide in the installation groove and be pushed outward. However, because of the provision of the elastic limiter 723, the stopper 722 will not fall off, but will tightly abut against the outer wall of the expanded diameter portion 121, thereby ensuring that the O-ring can be pushed onto the expanded diameter portion 121 and the expanded diameter column 12;

[0065] After the expansion is completed, the push cylinder 9 drives the push plate 10 to retract and reset, and then the horizontal drive cylinder 17 and the vertical drive cylinder 22 cooperate to lift the first feeding column 71 upward away from the expanded diameter portion 121 and move the second feeding column 81 to above the expanded diameter portion 121; at the same time, the first feeding column 71 will return to the top of the feeding point 5;

[0066] Then, the second feeding column 81 is dropped down and docked with the diameter expansion portion 121. Subsequently, the diameter expansion cylinder 13 is activated, driving the diameter expansion push plate 14 to rise upward. Under the action of the diameter expansion push plate 14, the expanded O-ring is pushed out from the diameter expansion column 12 (diameter expansion portion 121) and is mounted on the second feeding column 81. At the same time, the first feeding column 71 is also dropped down and inserted into the feeding point 5, and the new O-ring to be expanded is mounted on the first feeding column 71.

[0067] Then, the horizontal drive cylinder 17 and the vertical drive cylinder 22 cooperate to make the second material taking column 81 rise and move away from the diameter expansion portion 121. At the same time, the diameter expansion cylinder 13 retracts and drives the diameter expansion push plate 14 to reset. Then, the second material taking column 81 with the expanded O-ring is removed. At the same time, the first material taking column 71 with the O-ring to be expanded is returned to the top of the diameter expansion portion 121.

[0068] The feeding mechanism is made to fall again, and the pushing cylinder 9 is started to drive the pushing plate 10 to slide downward. The O-ring after the diameter expansion mounted on the second feeding column 81 will be pushed out from the second feeding column 81 under the action of the pushing plate 10 and the buffer washer 82; at this time, the second feeding column 81 can directly dock the workpiece, thereby completing the assembly of the O-ring; at the same time, the O-ring to be expanded mounted on the first feeding column 71 will also be pushed out from the first feeding column 71 under the action of the pushing piece 72, and mounted on the expanding portion 121, thereby starting the next round of diameter expansion.

[0069] At this point, the above process is circulated to simultaneously complete the material removal, diameter expansion, and transfer assembly of the O-ring.

[0070] In summary, the embodiment of the present application provides an O-ring feeding and assembly device, which, when in use, feeds the O-ring to be expanded to a position near the above-mentioned material-picking mechanism through the above-mentioned feeding mechanism, and then, under the driving control of the above-mentioned driving mechanism, cooperates with the above-mentioned material-picking mechanism to take out the O-ring to be expanded, and further transfers it to the above-mentioned diameter-expanding mechanism, and uses the above-mentioned diameter-expanding mechanism to perform diameter-expanding on the O-ring. After the diameter-expanding process is completed, the above-mentioned driving mechanism cooperates with the above-mentioned material-picking mechanism to take out the O-ring after the diameter-expanding process from the above-mentioned diameter-expanding mechanism and transfers it to the outside for product assembly; while the above-mentioned material-picking mechanism takes out the O-ring after the diameter-expanding process for transfer and assembly, the above-mentioned material-picking mechanism will also simultaneously take out the newly-fed O-ring to be expanded from the above-mentioned feeding mechanism and transfer it to the above-mentioned diameter-expanding mechanism, thereby realizing the continuous cycle operation of the equipment.

It can simultaneously complete the feeding, diameter-expanding, transfer and assembly work of the O-ring, effectively improve work efficiency, save manpower consumption, and ensure product assembly quality.
