The first pipe 31 and the second pipe 33 are each provided with at least one second through hole 314, and the first sensor 312 is disposed in the second through hole 314.

[0041] In this embodiment, the feeding assembly 3 further includes a second sensor 315 inserted in the third through hole 316, a third sensor 333 inserted in the fifth through hole 335, a second blocking assembly 34 fixed at the fourth through hole 334, and a third blocking assembly 35 fixed at the sixth through hole 336.

[0042] like Figure 6 and Figure 7 As shown, the receiving assembly 4 includes a first base plate 40, at least one third pipe 41 and a limiting assembly 42. A sink 401 is provided on the first base plate 40, and a plurality of third openings 402 corresponding to the bolt holes of the plastic oil pan 110 are provided on the sink 401. A corresponding number of third pipes 41 are passed through the third openings 402. The limiting assembly 42 is arranged at the discharge port of the third pipe 41, and includes a first limiting member 420, a second limiting member 421, a first driving member 422 and a second driving member 423. The first limiting member 420 is arranged at the discharge port of the third pipe 41 and is fixedly connected to the first driving member 422. The first limiting member 420 is provided with a first groove 427 relative to the third pipe 41. The first groove 427 allows the bushing 100 to pass through. The receiving assembly 4 also includes at least one fifth cylinder 44. The fifth cylinder 44 is fixed on the frame 1 and one end of the fifth cylinder 44 is fixedly connected to the first bottom plate 40 to drive the first bottom plate 40 to move closer to and away from the loading assembly 3 .

[0043] In this embodiment, the first stopper 420 includes a pair of first side plates 425 and a connecting plate 428. The pair of first side plates 425 are fixed at both ends of the connecting plate 428, and a first baffle 426 is provided on the first side plate 425 at a position corresponding to the third pipe 41.

The first groove 427 and the second groove 432 have the same structure and are both fan-shaped, and the bushing 100 can fall. Furthermore, in order to avoid the problem of motion interference caused by two driving members acting on the same object at the same time, one of the second limiting members 421 is fixedly connected to the connecting plate 428 by screws, and is driven by the first driving member 422 together with the first limiting member 420, and the other second limiting member 421 is fixedly connected to the second driving member 423 by screws.

Furthermore, a plurality of limit blocks 511 are fixed to the second base plate 51 by screws. The position of the limit block 511 is determined by the plastic oil pan 110, and is used to limit the plane freedom of the plastic oil pan 110 on the second base plate 51. The press-fitting assembly 5 further includes a uniaxial motion module 50 , which is fixed on the frame 1 and fixedly connected to the third bottom plate 52 , and is used to drive the second bottom plate 51 and the third bottom plate 52 to reciprocate between the loading area 700 and the press-fitting area 800 .

[0045] The clamping assembly 53 is arranged above the second base plate 51, and includes a third driving member 531, a second fixed plate 532, at least one fourth guide rod 533, a fourth base plate 534 and at least one pressing rod 535. One end of the fourth guide rod 533 is fixed to the frame 1, and the other end is fixedly connected to the second fixed plate 532. A fourth guide hole 539 is provided on the fourth base plate 534, and the fourth guide rod 533 is sleeved in the fourth guide hole 539. The third driving member 531 is fixed to the second fixed plate 532 to drive the fourth base plate 534 to slide along the fourth guide rod 533. Optionally, the third driving member 531 can be a single-axis cylinder or an electric drive device with a deceleration system. The pressing rod 535 includes an inner rod 541, an outer cylinder 542 and an elastic member 537. In this embodiment, the elastic member 537 is a spring. The compression rod 535 includes an inner rod 541 and an outer tube 542. The inner rod 541 is inserted into the outer tube 542, and a clamp 543 is fixed to the inner rod 541. The elastic member 537 is clamped between the outer tube 542 and the clamp 543. Further, the cross-sectional diameter of the inner rod 541 is greater than the outer diameter of the bushing 100.

[0046] In this embodiment, for the sake of press-fitting effect and maintenance convenience, the press rod 535 and the fourth bottom plate 534 are further provided with a fifth bottom plate 538. The press rod 535 is fixed to the fifth bottom plate 538 by screws or other means, and the fifth bottom plate 538 is fixedly connected to the fourth bottom plate 534 by a plurality of connecting rods.

[0047] In this embodiment, a pair of first support rods 45, a second support rod 513 and a third support rod 536 are respectively fixed to the frame 1 at relative positions on the lower end surfaces of the first base plate 40, the second base plate 51 and the fourth base plate 534. When the first base plate 40 and the second base plate 51 are respectively driven by a pair of fifth cylinders 44, a pair of seventh cylinders 54 and the third driving member 531 to descend to the specified position, the first support rod 45, the second support rod 513 and the third support rod 536 can ensure that the first base plate 40, the second base plate 51 and the fourth base plate 534 can be braked smoothly.

[0048] In this embodiment, the clamping assembly 53 further includes a pair of sixth cylinders 512. The sixth cylinder 512 is a single-claw cylinder with a lever structure. When the second bottom plate 51 is not placed in the plastic oil pan 110, the controller 60 controls the clamping claws of the sixth cylinder 512 to open; when the second bottom plate 51 is not placed in the plastic oil pan 110, the controller controls the clamping claws of the sixth cylinder 512 to retract and clamp the plastic oil pan 110.

[0049] like Fig.10 As shown, the controller 60 located in the electric control box 6 is electrically connected to the multiple electric control movable parts and sensors in the above-mentioned feeding component 2, loading component 3, receiving component 4, and pressing component 5.

[0050] When using the bushing assembly mechanism, the staff first pours the bushing 100 to be assembled into the feed hopper 20, and presses the button on the electric control box 6 to start the machine. The piston of the first cylinder 201 below the feed channel 23 is lifted up to transfer the bushing 100 to the vibration plate 21. The bushing 100 enters the discharge pipe 22 under the vibration of the vibration plate 21, and falls into the first pipeline 31 from the first discharge port 221.

[0051] In the initial state, the second cylinder 321 of the first blocking assembly 32 in the first pipe 31 is in an extended state, and the first push rod 322 is extended through the first through hole 313 and is located inside the first pipe 31. After the bushing 100 falls into the first pipe 31 from the discharge pipe 22, it is blocked by the first push rod 322. The bushing 100 in the first pipe 31 accumulates continuously until the first sensor 312 above detects the bushing 100. The first sensor 312 sends a signal to the controller 60 to control the first cylinder 201 and the vibration plate 21 to stop moving, so that the bushing 100 no longer falls into the first pipe 31. Subsequently, the controller 60 controls the three-axis motion module 30 to move the second pipe 33 to below the second discharge port 311 of the first pipe 31.

[0052] In the initial state, the third cylinder 341 of the second blocking assembly 34 located in the second pipe 33 is in a retracted state, driving the second push rod 342 to retract; the third blocking assembly 35 is in an extended state, pushing the third push rod 352 through the sixth through hole 336 to be located inside the second pipe 33. After receiving the signal from the three-axis motion module 30, the controller 60 controls the second cylinder 321 to retract, thereby driving the first push rod 322 to retract, so that the bushing 100 falls into the second pipe 33 from the feed port 331 of the first pipe 31 in turn, and then is blocked by the third push rod 352.

[0053] After all the bushings 100 in the first pipe 31 fall into the second pipe 33, the controller 60 controls the three-axis motion module 30 to drive the second pipe 33 to run along a number of assembly points in sequence, and sequentially puts the sleeves 100 in the second pipe 33 into the third pipe 41 located on the first bottom plate 40. Specifically, when the second pipe 33 moves to the top of the target third pipe 41, at this time, the second pipe 33 is coaxial with the third pipe 41, and the controller 60 controls the fourth cylinder 351 to retract while controlling the third cylinder 341 to extend, so that the first bushing 100 in the lower middle of the second pipe 33 falls into the third pipe 41 by itself. At the same time, the second bushing 100 in the lower middle of the second pipe 33 is just held by the second push rod 342, ensuring that only one bushing 100 falls into the third pipe 41. Then the controller 60 controls the third cylinder 341 to retract and the fourth cylinder 351 to extend, so that the bushing 100 originally supported by the second push rod 342 falls onto the third push rod 352, and the other bushings 100 located above fall in turn. Then the three-axis motion module 30 continues to move to the third pipe 41 where the next material needs to be dropped, and repeats the above actions to ensure that only one bushing 100 falls from the second pipe 33 into the third pipe 41 each time.

[0054] Furthermore, each time a bushing 100 falls into the second pipe 33, the third sensor 333 sends a signal to the controller 60 for counting. When bushings 100 have fallen into all the third pipes 41, the three-axis motion module 30 drives the second pipe 33 back to the position directly below the first pipe 31 to wait for the next loading step. Before the loading assembly 3 completes the entire loading process, the first driving member 422 and the second driving member 423 located below the first bottom plate 40 extend, so that the first groove 427 and the second groove 432 of the limiting assembly 42 are staggered with the third pipe 41, so that the bushing 100 will not continue to fall under the resistance of the first baffle 426 and the second baffle 431.

[0055] Before the compaction step begins, Fig. 9As shown, the second bottom plate 51 and the third bottom plate 52 are located in the press-fitting area 800. The staff puts the plastic oil pan 110 into the area surrounded by the limit block 511 on the second bottom plate 51, and finally presses the button on the electric control box 6 to start the pressing step. The controller 60 controls the seventh cylinder 54 to retract, pulls the second bottom plate 51 to move downward along the third guide rod 522, and the second guide rod 521 passes through the bolt hole on the plastic oil pan 110, and at the same time, the sixth cylinder 512 claws are retracted to clamp the plastic oil pan 110. The single-axis motion module 50 drives the second bottom plate 51, the third bottom plate 52 and the plastic oil pan 110 to move to the loading area 700. Driven by the fifth cylinder 44, the first bottom plate 40 slides downward along the first guide rod 43 until it abuts against the first support rod 45. At this time, the second bottom plate 51 and the plastic oil pan 110 located on the second bottom plate 51 are just located in the projection area below the first bottom plate 40. Specifically, the axes of the second pipe 33 and the third pipe 41 are colinear. Then, the first driving member 422 and the second driving member 423 located below the first bottom plate 40 drive the first stopper 420 and the second stopper 421 to move away from each other. The axes of the first groove 427 and the second groove 432 coincide with the axes of the discharge port of the third pipe 41 that was originally blocked by the first baffle 426 and the second baffle 431, so that the bushing 100 can leave the third pipe 41 and smoothly fall into the bolt hole of the plastic oil pan 110 under the guidance of the second guide rod 521.

[0056] The pressing step begins: the controller 60 controls the uniaxial motion module 50 to drive the second bottom plate 51 and the third bottom plate 52 with the plastic oil pan 110 and the bushing 100 to move to the bottom of the pressing assembly 53. Then, the third driving member 531 pushes the fourth bottom plate 534 to slide along the fourth guide rod 533, thereby driving the pressing rod 535 to press the bushing 100 into the bolt hole of the plastic oil pan 110. The elastic member 537 located between the inner rod 541 and the outer cylinder 542 on the pressing rod 535 provides sufficient pressure while also playing a role of buffering and shock absorption, thereby preventing the hard contact between the pressing rod 535 and the bushing 100 during the pressing process from causing damage to the plastic oil pan 110. After the pressing is completed, the third driving member 531 drives the entire pressing assembly 53 back to the initial position and waits for the next pressing. The controller 60 controls the seventh cylinder 54 to extend, pulling the second base plate 51 to move upward along the third guide rod 522. At the same time, the claw of the sixth cylinder 512 extends to release the plastic oil pan 110, waiting for the staff to remove the plastic oil pan 110 with the bushing 100 installed.
