At this time, the pin driving member 331 drives the pin push rod 332 to move along the push rod guide hole 3331, the second pin positioning groove 31431 and the positioning hole 3211, and pushes the pin in the second pin positioning groove 31431 into the mounting hole 62 of the handle 61.

[0076] The riveting pin device provided in this embodiment can respectively set the above-mentioned pin insertion mechanism 3 and pin feeding cylinder on both sides of the transmission mechanism 1 in the width direction. The pin feeding cylinder positions the surge protector 6 on the transmission mechanism 1 and pushes it into the limiting groove 3213; correspondingly, a pin ejection cylinder 322 can be set on the limiting frame 321. When the surge protector 6 completes the pin insertion process, the pin ejection cylinder 322 pushes the surge protector 6 from the limiting groove 3213 to the transmission mechanism 1, and the transmission mechanism 1 transmits the surge protector 6 to the testing station.

[0077] In this embodiment, a pin push-blocking cylinder 323 can also be provided on the limit frame 321. When the surge protector 6 enters the limit groove 3213, the pin push-blocking cylinder 323 applies a thrust to the surge protector 6 toward the side of the limit frame 321 where the positioning hole 3211 is provided, so as to improve the reliability and positioning accuracy of the pin insertion process.

[0078] In this embodiment, the testing mechanism 5 includes a tripping assembly 51 and a withstand voltage test assembly 52. ​​The tripping assembly 51 is used to toggle the handle 61 of the surge protector 6 to put the surge protector 6 in a tripped state, and the withstand voltage test assembly 52 is used to perform a withstand voltage test on the surge protector 6.

[0079] For details, please refer to Fig. 9 and Fig.10 The trip assembly 51 includes a first trip drive 511, a second trip drive 512, a trip limiter 513 and a trip pull block 514. The first trip drive 511 is connected to the trip limiter 513 in a transmission manner to limit and position the surge protector 6. The second trip drive 512 is disposed on the trip limiter 513 and is connected to the trip pull block 514 in a transmission manner. When the surge protector 6 moves to the trip position, the first trip drive 511 drives the trip limiter 513 to descend so that the trip limiter 513 limits the surge protector 6. Then, the second trip drive 512 drives the trip pull block 514 to move the handle 61 of the surge protector 6 so that the surge protector 6 is in a trip state. The surge protector 6 in the trip state is transmitted to the withstand voltage test position through the transmission mechanism 1.

[0080] Please refer to Fig.11 The withstand voltage test assembly 52 includes a withstand voltage driving member 521, a withstand voltage limiting member 522 and a withstand voltage test probe 523. The withstand voltage limiting member 522 is connected to the withstand voltage driving member 521 by transmission, and the withstand voltage test probe 523 is arranged on the withstand voltage limiting member 522. When the transmission mechanism 1 transmits the surge protector 6 to the withstand voltage test station, the withstand voltage driving member 521 drives the withstand voltage limiting member 522 to descend to limit the surge protector 6. When the withstand voltage limiting member 522 descends, the withstand voltage test probe 523 can abut against the withstand voltage test structure to perform a withstand voltage test on the surge protector 6.

[0081] In this embodiment, the riveting pin device may also be provided with a robot to unload the surge protector 6 that has completed the withstand voltage test and place the surge protector 6 in an unloading tray.

[0082] In summary, the riveting pin equipment provided by the present invention can realize the riveting process and the pin insertion process of the surge protector 6. The riveting pin equipment has high positioning accuracy and high reliability. It can reduce the labor of manual operation and improve the production efficiency and yield rate of the surge protector 6.
