[0002] In automotive piping, quick-connect fittings are often used to achieve fast connections when access space is limited or connections are difficult. Because quick-connect fittings are used in environments with stringent sealing requirements, they are often fitted with several O-rings to ensure a tight seal. Sealing O-rings are rubber sealing rings with a circular cross-section. They are called O-rings because of their O-shaped cross-section. They offer advantages such as excellent sealing performance, compact structure, reliable function, long service life, and low friction resistance.

[0003] Currently, quick-connect fittings typically feature two O-rings to ensure a tight seal. The assembly process between the quick-connect fitting and the O-rings is typically manual, resulting in slow and inefficient assembly.

[0049] In the above technical solution, the unloading mechanism 8 includes an unloading transverse displacement cylinder 81, an unloading lifting cylinder 82, an unloading pneumatic clamping finger 83, and an unloading conveyor belt 84. The piston rod of the unloading transverse displacement cylinder 81 is connected to a unloading transverse displacement slider, which drives the unloading transverse displacement slider to move. The unloading lifting cylinder 82 is connected to the unloading transverse displacement slider. The piston rod of the unloading lifting cylinder 82 is connected to a unloading lifting slider, which drives the unloading lifting slider to move. The unloading pneumatic clamping finger 83 is mounted on the unloading lifting slider. The unloading pneumatic clamping finger 83 is a two-claw pneumatic finger, and both clamping claws of the unloading pneumatic clamping finger 83 are equipped with unloading clamping blocks, and the two unloading clamping blocks are formed with unloading clamping grooves on the opposite sides. The unloading transverse movement cylinder 81 and the unloading lifting cylinder 82 drive the unloading pneumatic clamping fingers 83 to move, and the unloading pneumatic clamping fingers 83 clamp the quick-connector on the rotating fixture. The unloading transverse movement cylinder 81 and the unloading lifting cylinder 82 drive the unloading pneumatic clamping fingers 83 and the quick-connector to move, and the unloading pneumatic clamping fingers 83 release the quick-connector, causing the quick-connector to fall onto the unloading conveyor belt 84, and the unloading conveyor belt 84 drives the quick-connector to move for unloading.

[0050] The present invention operates as follows: The pneumatic feeding finger 21 grips the quick-connect connector in the loading fixture. The loading transverse cylinder 23 and the loading lift cylinder 24 move the gripped quick-connect connector into the rotating fixture. The rotating disc 32 moves the rotating fixture and quick-connect connector between one of the positioning mechanisms 10 and the assembly mechanism 4.

[0051] Positioning action: The positioning pneumatic fingers 102 drive the two positioning gripping blocks 103 to move toward each other. These gripping blocks 103 clamp the quick-connect connector on the rotating fixture, which is located within the arc-shaped groove, thereby positioning the quick-connect connector. The quick-connect connector is provided with an upper annular groove and a lower annular groove for a sealing O-ring. The positioning mechanism 10 grips the connector below the lower annular groove.

[0052] Assembly action: The pushing cylinder 421 drives the pushing plate 422 to move until the feed trough 423 and the feed notch are aligned and connected, the rotary vibration loader 41 loads the sealing O-ring into the feed trough 423, and the pushing cylinder 421 drives the pushing plate 422 and the sealing O-ring to move until the feed trough 423 is located directly above the material insertion hole 425. The assembly transverse cylinder 431 and the assembly lifting cylinder 441 drive the assembly material picking assembly 45 and the material pressing assembly 46 to move. At this time, the four sealing ring picking blocks 452 are in a gathered state near the center of the circle. The picking parts 455 of the four sealing ring picking blocks 452 are spliced ​​into a cylindrical insertion block. The insertion block moves to just above the picking insertion hole 425. The assembly lifting cylinder 441 drives the insertion block downward. The insertion block passes through the sealing O-ring in the feed trough 423 and enters the picking insertion hole 425. The insertion limit block 426 and the picking positioning part 454 limit the downward movement of the insertion block. The four-claw cylinder 451 drives the four sealing ring picking blocks 452 to disperse and move away from the center of the circle. The sealing ring picking block 452 stretches the sealing O-ring, and the inner wall of the sealing O-ring is in close contact with the sealing ring picking block 452. At this time, the sealing O-ring moves synchronously with the sealing ring picking block 452. The arc-shaped material-removing portion 455 can be spliced ​​into a cylindrical insertion block in a gathered state, which is convenient for insertion into the sealing O-ring, and can also make the sealing O-ring expand more evenly in a dispersed state. The arc-shaped surface avoids damage to the sealing O-ring, making the opening circumference of the sealing O-ring small, preventing the sealing O-ring from excessive opening and extreme damage.

[0053] The assembly transverse movement cylinder 431 and the assembly lifting cylinder 441 drive the assembly material picking assembly 45, the pressing assembly 46 and the sealing O-ring to move out of the material picking insertion hole 425, and make the four-claw cylinder 451 be located directly above the quick connector positioned by the positioning mechanism 10. The assembly lifting cylinder 441 drives the assembly material picking assembly 45 and the sealing O-ring to move downward, and the top of the quick connector enters between the four sealing ring picking blocks 452. The pressing lifting cylinder 461 drives the pressing plate 462 to move downward, and the pressing plate 462 drives the sealing O-ring sleeved on the sealing ring picking block 452 to move downward. The pressing plate 462 contacts the positioning clamping block 103, and the pressing plate 462 stops moving. At this time, the sealing O-ring is separated from the sealing ring picking block 452, and the sealing O-ring is located in the lower annular groove. The elastic force of the sealing O-ring is released and reset to the unexpanded state, completing the sealing O-ring sleeved in the lower annular groove of the quick connector.

[0054] The rotating disc 32 drives the rotating clamp and the quick-connect connector with a sealing O-ring to move between another set of positioning mechanisms 10 and the assembly mechanism 4, repeating the positioning and assembly actions. The positioning clamping block 103 of the positioning mechanism 10 is clamped below the upper annular groove and above the lower annular groove. The positioning clamping block 103 positions the pressing plate 462 for downward movement of the pressing material, and the second sealing O-ring is set in the upper annular groove of the quick-connect connector.

[0055] The rotating disc 32 drives the rotating fixture and the quick-connect fitting, which is fitted with two sealing O-rings, to rotate sequentially through the imaging mechanism, oiling mechanism 6, capping mechanism 7, and discharge mechanism 8. The imaging mechanism verifies whether the quick-connect fitting has two sealing O-rings, whether they are properly installed, and whether they are broken or damaged. The oiling mechanism 6 applies lubricant to the surfaces of the two sealing O-rings. The capping mechanism 7 installs a protective cover on the quick-connect fitting. The discharge mechanism 8 discharges the product.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should fall within the scope of protection of the present invention.
