When the proximity switch 6-3 detects that the hand of a worker is in a riveting area (namely, when the worker places the relay contact 10 to be riveted on the riveting seat 2-3-6), the sliding table of the protective sliding table cylinder 5-1 drives the protective sheet 5-2 to move forwards, so that two U-shaped ends of the protective sheet 5-2 are respectively positioned above 2 guide sleeves 2-3-6-1 of the riveting seat 2-3-6, and 2 cylindrical guide rods 2-3-41 on the punch connecting seat 2-3-1 can be prevented from entering the guide sleeves 2-3-6-1, so that the guide seat 2-3-5 is prevented from continuously moving downwards to crush the worker, and the safety is improved. When a worker puts the relay contact 10 well, the proximity switch 6-3 detects that the hand of the worker is taken away, the sliding table of the protective sliding table cylinder 5-1 drives the protective sheet 5-2 to move backwards, and the equipment enters a state of waiting riveting operation. At this time, the device is started, the motor 2-11 of the driving assembly 2-1 drives the driving disc 2-13 to rotate 180 degrees counterclockwise (see fig. 7), in the process, the driving disc 2-13 makes the first connecting seat 2-22 move forward along the first horizontal linear guide 2-26 through the first connecting rod 2-21, so that the upper part of the rotating arm 2-23 rotates forward, and the first mounting seat 2-25 moves downward along the first vertical linear guide 2-41 and the second vertical linear guide 2-42 through the downward movement of the lower part of the rotating arm 2-23.

The motor 2-11 of the driving assembly 2-1 continuously drives the driving disc 2-13 to continuously rotate 180 degrees, in the process, the driving disc 2-13 enables the first connecting seat 2-22 to move backwards along the first horizontal linear guide rail 2-26 through the first connecting rod 2-21, so that the upper part of the rotating arm 2-23 rotates backwards, and the lower part of the rotating arm 2-23 moves upwards to enable the first mounting seat 2-25 to move upwards along the first vertical linear guide rail 2-41 and the second vertical linear guide rail 2-42. The punch connecting seat 2-3-1 moves upwards, and the guide seat 2-3-5 is driven to move upwards by the equal-height screw 2-3 a; meanwhile, the material blocking sliding table cylinder 3-1 drives the material blocking plate 3-2 to enable the material blocking part of the material blocking plate 3-2 to move leftwards to a position between the material outlet of the material discharging inclined plane 2-3-6c of the riveting seat 2-3-6 and the material inlet of the first material guide groove 4-1, and the material outlet of the material discharging inclined plane 2-3-6c of the riveting seat 2-3-6 is disconnected with the material inlet of the first material guide groove 4-1. After riveting is completed, a worker takes out the riveted relay contact 10 from the riveting seat 2-3-6 to enable the riveted relay contact to slide down along the discharging inclined plane 2-3-6 c. And is blocked by the blocking part of the blocking plate 3-2. When riveting operation is carried out for the second time, when the material blocking sliding table cylinder 3-1 drives the material blocking plate 3-2 to enable the material blocking part of the material blocking plate 3-2 to move out of the position between the material outlet of the material outlet inclined plane 2-3-6c of the riveting seat 2-3-6 and the material inlet of the first material guide groove 4-1, the riveted relay contact 10 falls into the first material guide groove 4-1 from the material outlet inclined plane 2-3-6c, falls into the second material guide groove 4-2 along the first material guide groove 4-1, and when the riveted relay contact passes through the third photoelectric sensor 6-4, the riveted relay contact is counted by the third photoelectric sensor 6-4 and finally falls into the material collecting basket 4-3.
