[0037] The first feeding mechanism 10 is used to convey orderly arranged tires to the assembly mechanism 40. The second feeding mechanism 20 is used to convey orderly arranged universal joints to the assembly mechanism 40. The third feeding mechanism 30 is used to convey orderly arranged press studs to the assembly mechanism 40. After the tires are conveyed to the assembly mechanism 40, the universal joints are conveyed to the assembly mechanism 40 and placed on the tires by the assembly mechanism 40. After the press studs are conveyed to the assembly mechanism 40, the assembly mechanism 40 presses them down to connect the perforations of the universal joints and the perforations of the tires, thereby assembling the universal joints and the tires together.

[0038] Both the first feeding mechanism 10 and the second feeding mechanism 20 can adopt existing feeding mechanisms. In this embodiment, both the first feeding mechanism 10 and the second feeding mechanism 20 output the to-be-assembled parts arranged in an orderly manner, namely tires and universal joints, by means of vibration plate vibration transmission for feeding. Specifically, the first feeding mechanism 10 includes a first vibration plate 11 and a first conveyor belt 14. A first spiral rising track 12 is provided in the first vibration plate 11. One end of the first conveyor belt 14 is connected to the output end of the first spiral rising track 12, and the other end of the first conveyor belt 14 extends to the assembling mechanism 40. In order to ensure that the tire is in a horizontally placed state when it is output from the output end of the first spiral rising track 12, a first feeding rod 13 is provided at the top of the first vibration plate 11. The first feeding rod 13 is located at the output end of the first spiral rising track 12.

One end of the second conveyor belt 24 is connected to the output end of the second spiral rising track 22, and the other end of the second conveyor belt 24 extends to the assembling mechanism 40. In order to make the universal joints arranged in a hanging state on the second conveyor belt 24, a second feeding rod 23 is provided at the top of the second vibration plate 21, at the output end of the second spiral rising track 22. The second conveyor belt 24 is an inclined suspension rod, which is inclined downward from the output end of the second spiral rising track 22 to the assembling mechanism 40. In order to ensure that the universal joints do not fall off the inclined suspension rod, the second conveyor belt 24 is also provided with an inclined retaining rod. The shape of the inclined retaining rod changes along with the inclined suspension rod, so that the distance between the inclined retaining rod and the inclined suspension rod is just enough to clamp the universal joints.

[0040] Please also refer to Figure 7 and Figure 8, in this embodiment, the third feeding mechanism 30 includes a material box 31 for storing press studs. A groove 311 is provided on the side wall of the material box 31, and a rotary feeding member is provided in the groove 311. The rotary feeding member includes a rotary ring 32 and an arc-shaped plate 33 fixedly connected to the rotary ring 32. A press stud clamping belt 34 is further provided in the material box 31, and the press stud clamping belt 34 extends from the central position of the rotary ring 32 to the outside of the material box 31. The press studs rotate inside the material box 31, and the arc-shaped plate 33 rotates along with the rotary ring 32. When the arc-shaped plate 33 rotates to the lowest position, it hooks the press studs in the material box 31; when the arc-shaped plate 33 rotates to the highest position, the press studs hooked on the arc-shaped plate 33 fall off, and the fallen press studs are inserted on the press stud clamping belt 34 and are transmitted outside the material box 31 along with the press stud clamping belt. An air transmission unit is further provided outside the material box 31, and the air transmission unit includes an air duct 35 and an air compressor. One end of the air duct 35 is connected to the discharge port of the press stud clamping belt 34, and the other end is connected to the assembly mechanism 40. With the air compressor extracting and compressing air as the power, the press studs are arranged and transmitted orderly in the closed air duct 35.

[0041] Please also refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the assembly mechanism 40 includes a base frame 41, a tray 42 fixed on the base frame, and a coaxial turntable 43 installed on the tray. Two or more through holes 431 are provided on the coaxial turntable 43, and the shape of the through holes 431 matches that of the tire. The tire output by the first feeding mechanism 10 is transmitted into the through holes and is assembled with the universal joint and the press studs in the through holes. Specifically, the method of feeding the tire output by the first feeding mechanism 10 into the through holes is as follows: The assembly mechanism 40 is provided with a first material receiving unit, and the first material receiving unit includes a first material receiving seat 441 provided above the material receiving station of the tray. The first material receiving seat is provided with a first material loading port 442. The other end of the first conveyor belt 14 extends to the first material receiving seat. The first material loading port is used to receive the tire sent out by the first conveyor belt 14. A pressing cylinder 43 is provided above the first material loading port. When the pressing cylinder extends, it presses down the tire on the first material loading port so that the tire is placed in the through hole below the first material loading port.

[0042] The assembly mechanism 40 further includes a second material receiving unit. The second material receiving unit includes a second material receiving seat 451 disposed above the assembly station of the tray, a lifting cylinder 453 for driving the lifting of the second material receiving seat, and a material transfer manipulator 46. The second material receiving seat is provided with a second material loading port 451, and the shape of the second material loading port matches that of the universal joint, so that the second material loading port can carry the universal joint. The material transfer manipulator transfers the universal joint on the second conveyor belt 24 to the second material loading port. The specific method is as follows: The material transfer manipulator includes a clamping jaw 462, a rotary cylinder 461 for driving the clamping jaw to open or close, and a moving component for driving the rotary cylinder to move back and forth between the discharge port of the second conveyor belt 24 and the assembly station. The moving component drives the rotary cylinder to move to a position opposite to the discharge port of the second conveyor belt 24. The rotary cylinder drives the clamping jaw to open to pick up the universal joint at the discharge port of the second conveyor belt 24. Then the rotary cylinder drives the clamping jaw to close to clamp the universal joint. The moving component drives the rotary cylinder to move above the second material loading port. Then the rotary cylinder drives the clamping jaw to open so that the clamped universal joint falls on the second material loading port. At this point, the lifting cylinder drives the second material receiving seat to descend so that the second material receiving port is placed above the tire, so that the universal joint is placed above the tire.

[0043] The assembly mechanism 40 further includes a nail pressing unit. The nail pressing unit includes a nail discharging member located above the second material loading port and a nail pressing cylinder for driving the lifting of the nail discharging member. The nail discharging member is provided with a nail pressing inlet and a nail pressing outlet communicating with the nail pressing inlet. The nail pressing inlet communicates with the discharge port of the third feeding mechanism 30, that is, communicates with the other end of the pneumatic pipeline 35. The nail is fed into the nail discharging member through the pneumatic pipeline 35 via the nail pressing inlet and exits through the nail pressing outlet, and is inserted into the perforations of the universal joint and the tire. Under the action of the nail pressing cylinder driving the nail discharging member to press down, the nail presses the universal joint against the tire, completing the assembly.

[0044] In an embodiment, the nail pressing clamping belt 34 includes two symmetrically arranged clamping plates. The gap between the two clamping plates matches the body of the nail. The body of the nail is clamped by the two clamping plates, and the nail head hangs on the tops of the two clamping plates.

[0045] In an embodiment, in order to enable the redundant nails that fall on the nail pressing clamping belt 34 and cannot be clamped by the two clamping plates to be re-fed and arranged, a material sweeping member 36 is provided above the nail pressing clamping belt 34. The material sweeping member 36 rotates in the material box to sweep the redundant nails on the nail pressing clamping belt 34, so that the redundant nails fall to the bottom of the material box and are hooked up by the arc plate for re-feeding.

[0046] In an implementation, the moving component includes a slide rail 464 fixed on the base frame, a slider 463 slidably connected to the slide rail, and a moving cylinder 465 for driving the slider to move back and forth. The rotary cylinder is installed on the slider. In order to enable the rotary cylinder to also move up and down to adjust the height, the moving component is further provided with an adjusting cylinder 466 for driving the rotary cylinder to move up and down.

[0047] In an implementation, a finished product discharge port is provided on the tray, and a finished product channel 421 is provided below the tray. The finished product channel is communicated with the finished product discharge port.
