[0023] Reference Figure 3-Figure 4The feeding mechanism 2 includes a rotating motor 201, a fixed shaft 202, a driving wheel 203, a driven wheel 204, a turntable 205, a transmission rod 206, a rotating shaft 207, a cross bar 208, a connecting block 209, a support plate 210, and a slider 211. A rotating motor 201 is provided on one side of the mounting groove 10, a driving wheel 203 is provided on one side of the rotating motor 201, a driven wheel 204 is meshedly connected to one side of the driving wheel 203, a fixed shaft 202 is provided on one side of the driven wheel 204, and the other end of the fixed shaft 202 is fixedly connected to one side of the mounting groove 10, and the other side of the driven wheel 204 is meshedly connected to the driven wheel 204. A turntable 205 is provided, a rotating shaft 207 is provided on one side of the turntable 205, a transmission rod 206 is provided on the outside of one end of the rotating shaft 207, a connecting block 209 is provided on one side of one end of the transmission rod 206, and a support plate 210 is provided on the upper end of the connecting block 209. When the rotating motor 201 is started, it drives the driving wheel 203 to rotate, the driving wheel 203 drives the driven wheel 204 on one side to rotate, the driven wheel 204 drives the turntable 205 on one side to rotate, the rotating shaft 207 on the outside of the turntable 205 drives the transmission rod 206 to rotate, and the transmission rod 206 drives the support plate 210 on the upper end to move. The upper die punch 14 and the lower end downward pressure detection mechanism are used for corresponding detection. If the rivet 13 exists, the next punching is carried out. If the rivet 13 is not detected, the work is stopped.

[0024] Reference Figure 3-Figure 4 When the support plate 210 is about to reach the highest point, the upper machine mold 9 will be lifted up and carried by the support plate 210 for directional movement. As the support plate 210 moves, it will be placed on the support block 8 to achieve the purpose of moving the machine mold 9 on the support block 8. A second cylinder 7 is provided at the upper end of the mounting platform 1, and a second support 6 is provided at the upper end of the second cylinder 7. A support block 8 is provided at the upper end of the second support 6. The support block 8 is used to support the machine mold 9. An organic mold 9 is provided at the upper end of the support block 8. Rivets 13 are evenly provided on the upper end of the machine mold 9, and the rivet 13 in the middle is provided between the upper die punch 14 and the inner top 15.

[0025] Reference Figure 2The detection mechanism includes a partition 16, which is arranged at the lower end of the inner top 15, and a spring 17 is arranged at the lower end of the partition 16. A push rod 18 is arranged at the lower end of the partition 16, and a micro switch 19 is arranged at the lower end of the push rod 18. The inner top 15 squeezes the partition 16 downward, and the partition 16 compresses the spring 17 downward. The partition 16 moves downward, and the push rod 18 installed at the lower end of the partition 16 touches the micro switch 19 to complete the closed circuit. The micro switch 19 is electrically connected to the rotating motor 201 and the hydraulic rod 12. A number of feet 3 are provided at the lower end of the mounting platform 1 to fix the mounting platform 1. The micro switch 19 is arranged on one side inside the mounting platform 1.

[0026] Working principle: When the mold of this structure is closed, the upper die punch 14 presses the rivet 13 onto the machine mold 9. The rivet 13 presses the inner push 15 downward to press the partition 16 to squeeze the spring 17. The partition 16 drives the push rod 18 to squeeze the push rod 18 to contact the spring of the micro switch 19. The micro switch 19 transmits a signal to the hydraulic rod 12. If the rivet 13 is OK, the hydraulic rod 12 will be retracted, the spring 17 will return to its original position, the feeding mechanism 2 will rotate, and the support plate 210 will move the machine mold to detect the next rivet 13.

[0027] When the mold is closed and rivet 13 is missed, the inner top 15 has no compression spring 17 and does not drive the top rod 18 to contact the spring of the micro switch 19, and no transmission signal is sent to the hydraulic rod 12. The rivet 13 is judged to be NG, and the hydraulic rod 12 stops running, completing the rivet missing inspection.

[0028] The above circuit switching and signal transmission control principles belong to the existing technology application and will not be detailed here.
