[0026] Example:

[0027] An automated assembly line for tensioning wheels, such as Figure 1 As shown, the system includes a workbench 1, on which a turntable 1001 is rotatably connected. Ten material trays 1011 are arranged evenly along the circumference of the turntable 1001, and the number of material trays 1011 matches the number of functional workstations. During operation, the turntable 1001 rotates according to the program, causing the material trays 1011, carrying tension wheels, to enter the corresponding workstations.

[0028] like Figure 1 As shown, the workbench 1 is equipped with a surface inspection station 2, which is located at the beginning of the production line. The surface inspection station 2 includes a recognition camera 21, which is mounted on the workbench 1 and positioned inside the position turntable 1001. During operation, the recognition camera 21 inspects the tensioning roller from both sides and identifies the codes on the tensioning roller.

[0029] like Figure 1 As shown, the workbench 1 is equipped with a material loading and inspection station 3, which is located after the surface inspection station 2. The material loading and inspection station 3 includes an infrared photoelectric detector 31, which is mounted on the workbench 1, with its probe pointing towards the material tray 1011. During operation, the infrared photoelectric detector 31 scans the tensioning wheel to check whether the material is loaded correctly.

[0030] like Figure 1 and Figure 2As shown, the workbench 1 is equipped with a riveting station 4, which is located after the material loading and inspection station 3. The riveting station 4 includes a hydraulic cylinder 41 and a support 45. The support 45 is fixed on the workbench 1, and the hydraulic cylinder 41 is fixed on the support 45, thus fixing it to the workbench 1. The piston rod of the hydraulic cylinder 41 is connected to a pressing head 42. A mounting plate 451 is slidably connected to the support 45, and the mounting plate 451 can slide vertically. The pressing head 42 is connected to the mounting plate 451. A reducer 43 is mounted on the mounting plate 451, and a belt 44 is provided between the shaft of the reducer 43 and the pressing head 42. During operation, after the tension wheel is in position, the hydraulic cylinder 41 starts, the pressing head 42 moves downward, and then the reducer 43 starts to rotate the pressing head 42, pressing the rivet into the tension wheel.

[0031] like Figure 1 and Figure 3 As shown, the workbench 1 is equipped with a pre-torsion station 5, which is located after the riveting station 4. The pre-torsion station 5 includes a second reducer 51 and a second bracket 53. The second bracket 53 is mounted on the workbench 1, and the second reducer 51 is fixed to the workbench 1 via the second bracket 53. The second reducer 51 and the second bracket 53 are slidably connected by a slide rail, allowing the second reducer 51 to reciprocate vertically. The second reducer 51 is rotatably connected to a pre-torsion head 52. During operation, the second reducer 51, along with the pre-torsion head 52, descends, and the pre-torsion head 52 contacts the top of the tensioning wheel, initiating a single pre-torsion. This process is repeated for a total of 5 pre-torsion cycles to prevent the tensioner from jamming due to excessive damping.

[0032] like Figure 1 and Figure 4 As shown, the workbench 1 is equipped with a torque detection station 6, which is located after the pre-torsion station 5. The torque detection station 6 includes a reducer 61 and a support 63. The support 63 is mounted on the workbench 1, and the reducer 61 is vertically and vertically connected to the support 63, thus fixing the reducer 61 to the workbench 1. The reducer 61 is rotatably connected to a torque detection head 62. During operation, the reducer 61 descends, and the torque detection head 62 contacts the just-torsted tension wheel component.

[0033] like Figure 1 As shown, the workbench 1 is equipped with a pulley loading station 7, which is located after the torque detection station 6. A storage rack 71 is arranged beside the workbench 1. The storage rack 71 contains a platform 711 arranged circumferentially within it. A robotic arm 72 is movably connected to the storage rack 71. During operation, the robotic arm 72 grips the pulley 44 placed on the platform 711 and automatically places it onto the tensioning wheel component.

[0034] like Figure 1 and Figure 5As shown, the workbench 1 is equipped with a screw feeding station 8, which is located after the belt pulley feeding station 7. The screw feeding station 8 includes a vibrating hopper 81 and a tightening gun 82. The vibrating hopper 81 is arranged next to the workbench 1, and a pneumatic finger 811 is movably installed at the outlet of the vibrating hopper 81. The tightening gun 82 is mounted on the workbench 1. During operation, the pneumatic finger 811 picks up the screw from the outlet of the vibrating hopper 81 and places it into the screw position of the tensioner belt pulley 44. The tightening gun 82 automatically descends to drive the screw into the hole and checks that the tightening force is within the set range.

[0035] like Figure 1 As shown, the workbench 1 is equipped with a screw and flatness inspection station 9, which includes an infrared detector 91 and a camera 92, both mounted on the workbench 1. During operation, the infrared detector detects whether the screws are tightened properly, and the camera 92 detects the height of the belt pulley 44 on the mounting surface. Once both have been detected, the tension pulley rotates to the next station.

[0036] like Figure 1 As shown, the workbench 1 is equipped with a rivet inspection station 10, which is located after the screw and flatness inspection station 9. The rivet inspection station 10 includes a second camera 102 and a gripper 101. The second camera 102 is mounted on the workbench 1, and the gripper 101 is also mounted on the workbench 1, located on the side opposite to the second camera 102. During operation, the gripper 101 clamps the tension wheel, pointing its rivet head towards the lens of the second camera 102. The second camera 102 then takes a picture to check whether the rivet head is qualified.

[0037] like Figure 1 As shown, the workbench 1 is equipped with a marking station 11, which is located after the rivet inspection station 10. The marking station 11 includes a laser marking machine 111, which is mounted on the workbench 1. During operation, after the tension wheel inspection is completed, the laser marking machine 111 automatically marks the tension wheel.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
