[0044] Specifically, the bolt is grasped by the bolt profiling clamping jaw of the assembly clamping jaw cylinder 507, and then, by the action of the bolt transfer X-Y axis module 506, the bolt is horizontally translated and vertically lifted to achieve handling.

[0045] Preferably, in this embodiment, the plastic part and nut assembly unit includes an assembly seat 512, a plastic part limiting cylinder 514, a plastic part limiting plate 513, an inner cavity profiling mold 519, a jacking cylinder 516, a plastic part top sleeve 518, and an assembly cylinder 517.

[0046] Specifically, when assembling the plastic part and the bolt, the bolt linear feeder assembly conveys the screws to the bolt receiving cavity 511 of the side cutting seat 510. Subsequently, the bolt transfer X-Y axis module 506 drives the assembly jaw cylinder 507 to move above the side cutting seat 510. Then, the assembly jaw cylinder 507 descends to fix the bolt with the jaws of the assembly jaw cylinder 507. Next, the assembly jaw cylinder 507 ascends, and the bolt transfer X-Y axis module 506 drives the assembly jaw cylinder 507 to move above the assembly seat 512. The assembly jaw cylinder 507 descends to position the bolt within the assembly area, and at the same time, the assembly jaw cylinder 507 remains clamped without moving. Subsequently, the plastic part limit cylinder 514 operates to drive the plastic part limit plate 513 to move within the limit groove to perform upper limit on the plastic part. Then, the top-in cylinder 516 operates to drive the inner cavity profiling die 519 to ascend into the screw. Subsequently, the plastic part limit cylinder 514 operates again to make the notch 522 of the plastic part limit plate 513 completely located within the assembly hole 521. Then, the assembly cylinder 517 operates to drive the mounting plate and the plastic part top sleeve 518 to ascend, pushing the plastic part into the bolt to complete the assembly of the plastic part and the bolt.

The assembled plastic part and bolt are grabbed and transported by the equidistant handling module to the corresponding carrier seat 4 on the indexing turntable 2.

[0047] Before assembling the plastic part and the nut, the plastic part and nut assembly unit first performs upper limit on the plastic part, and then inserts the inner cavity profiling die 519 into the inner hole of the bolt to prevent the plastic part from deforming when being nailed into the inner hole of the bolt. Subsequently, the plastic part is inserted into the bolt, thus completing the assembly of the plastic part and the bolt and ensuring that neither of them is damaged or deformed during assembly.

[0048] Preferably in this embodiment, the O-ring assembly mechanism 6 includes an O-ring linear feeder assembly, a heating receiving seat 603, and an assembly detection device. The O-ring linear feeder assembly is connected to the heating receiving seat 603. The assembly detection device includes an O-ring handling X-Y axis module 605, a detection component, and an assembly component. A substrate 606 is installed at the moving and lifting end of the O-ring handling X-Y axis module 605.

The assembly component includes a three-jaw cylinder 608, a push-out cylinder 607, and an O-ring push plate 609. The three-jaw cylinder 608 and the push-out cylinder 607 are vertically arranged side by side on the substrate 606. An inner support profiling jaw 610 is installed at the output end of the three-jaw cylinder 608. The O-ring push plate 609 is horizontally arranged, with one end connected to the piston rod of the push-out cylinder 607 and the other end provided with a mating hole. The O-ring push plate 609 is sleeved on the inner support profiling jaw 610 through the mating hole.

[0049] Specifically, the O-ring linear feeder assembly conveys the O-ring to the heating and material-receiving seat 603. Subsequently, the heating and material-receiving seat 603 heats the O-ring. Then, the O-ring handling X-Y axis module 605 moves the three-jaw cylinder 608 downwards to above the heating and material-receiving seat 603. Subsequently, the inner-supporting profiling jaws 610 of the three-jaw cylinder 608 perform inner-supporting clamping on the O-ring. Then, the O-ring handling X-Y axis module 605 drives the three-jaw cylinder 608 to move above the carrier seat 4 of the indexing turntable 2. Subsequently, the inner-supporting profiling jaws 610 are lowered to the bolt on the carrier seat 4. Then, the pushing cylinder 607 acts, driving the pushing plate to descend and pressing down to push the O-ring, so that the O-ring is pushed to the bottom of the bolt, completing the assembly of the O-ring. Subsequently, the O-ring handling X-Y axis module 605 moves the three-jaw cylinder 608 to the heating and material-receiving seat 603 for the next grasping and assembly.

[0052] Specifically, after the O-ring is assembled on the bolt, the O-ring handling X-Y axis module 605 moves the detection component above the bolt of the carrier seat 4 of the indexing turntable 2. Subsequently, the detection cylinder 611 acts, driving the fixed rod 613 to descend, driving the detection sleeve 614 to descend and sleeve on the bolt. When the detection sleeve 614 contacts the O-ring, due to the continuous action of the detection cylinder 611, the detection sleeve 614 will move upwards relative to the fixed rod 613. Subsequently, the laser displacement sensor 612 will detect the displacement height of the detection sleeve 614, so as to judge whether the O-ring is installed in the specified position.

[0053] Preferably, in this embodiment, a through waist-shaped groove 615 is provided on the side of the fixed rod 613, a through mounting hole 616 is provided on the side of the detection sleeve 614, both ends of a horizontally arranged connecting rod 618 are inserted into the mounting hole 616 within the waist-shaped groove 615, the elastic member is a detection spring 617 sleeved on the fixed rod 613, and one end abuts against the detection sleeve 614 while the other end abuts against the piston rod of the detection cylinder 611;

[0054] Specifically, when the detection sleeve 614 moves upward when descending and contacting the O-ring, the detection spring 617 will be compressed. When the detection assembly returns to its original position and stops detecting, the detection spring 617 will release its elastic force, driving the detection sleeve 614 to move downward relative to the fixed rod 613 to return to its original position.

[0055] Preferably, in this embodiment, the O-ring linear feeder assembly includes an O-ring vibrating bowl and an O-ring linear feeding chute 602.

Subsequently, the O-rings slowly move along the O-ring linear feeding chute 602 and finally enter the heating receiving cavity 604 of the heating receiving seat 603.

[0057] Preferably, in this embodiment, an O-ring feeding protective cover 601 is provided outside the O-ring vibrating bowl. An O-ring feeding opening facing the O-ring vibrating bowl is provided at the top of the O-ring feeding protective cover 601.

[0060] Specifically, a batch of nuts are placed in the nut vibrating bowl. Through the vibrating feeding of the nut vibrating bowl, the nuts enter the nut linear feeding chute 702 one by one.

[0063] Specifically, after the nut linear feeder assembly conveys and loads the nuts into the material receiving and separating chamber 706 of the material receiving and separating seat 703, the separating cylinder 704 acts to drive the material receiving and separating seat 703 to move to a position facing the detection camera 707. Subsequently, the detection camera 707 performs visual inspection on the nuts on the material receiving and separating seat 703. If qualified, the nut installation component grabs and installs the nuts. If unqualified, the blowing component blows the nuts off, causing the nuts to fall into the NG collection bin 708.
