The workbench 1 is provided with a riveting station 2 and a detection station 3 arranged on one side of the riveting station 2. It should again be noted that the riveting station 2 and the inspection station 3 are only representative of a certain position on the table 1 and do not represent a specific structure. The punching unit may adopt a punching structure such as a punching head.
When the material belt 102 and the rivet 101 are riveted, the punching unit is arranged right above the riveting station 2, the material belt 102 is arranged between the punching unit and the workbench 1 and has a certain distance with the workbench, so that the material belt 102 can conveniently move between the punching unit and the workbench 1 along the length direction, and the rivet 101 can be riveted in a plurality of through holes 103 which are uniformly distributed on the material belt 102 along the length direction in sequence. The rivet 101 is fixed on the riveting station 2, the punching unit moves towards the riveting station 2 when punching operation is performed, the material belt 102 is pressed down to the top surface of the workbench 1, the through hole 103 on the material belt 102 is sleeved on the rivet 101 positioned on the riveting station 2, and then the rivet 101 is deformed under the punching of the punching unit, so that the riveting between the rivet 101 and the material belt 102 is realized. After the riveting is completed, the punching unit is lifted, the material belt 102 rebounds, and then the material belt 102 moves along the length direction of the material belt, so that the next through hole 103 on the material belt 102 is aligned with a new rivet 101 on the riveting station 2 up and down, and the material belt 102 and the rivet 101 are conveniently riveted for a new round. At this point, the rivet 101, which has just been riveted to the strip 102, is located above the inspection station 3.
