A first detection switch 7 is arranged between the first feeding mechanism 3 and the second feeding mechanism 4, and a second detection switch 8 is arranged between the second feeding mechanism 4 and the discharging mechanism 5. In this technical solution, the moving contact is placed in the material placing seat by the first feeding mechanism. The material placing seat rotates to the second feeding mechanism, and the stamping mechanism stamps the shaft head downward into the moving contact. Then, when the material placing seat passes through the discharging mechanism, the finished moving contact is taken away. The first detection switch is used to detect whether the moving contact is placed in place, and the second detection switch detects whether the riveting is successful. It has high working efficiency and high automation degree.

[0048] Both the first detection switch and the second detection switch adopt photoelectric switches.

[0049] The first feeding mechanism 3 includes:

The moving range of the first material taking assembly is between the end of the first feeding channel 32 and the material placing seat 6. The moving contacts in the first feeding channel are arranged in an orderly manner. The first material taking assembly takes out the moving contacts and places them in the material placing seat.

[0054] The first material taking assembly includes:

[0055] A first base 33, which is fixedly mounted on the frame 1;

[0056] A first sliding seat 34, which is horizontally slidably mounted on the first base 33;

The two cooperate to enable the first suction cup to move on the X-axis and Y-axis. The first hollow tube is connected to a vacuum pumping device (not shown) to enable the first suction cup to perform two actions of adsorption and release.

[0061] The second feeding mechanism 4 includes a second vibrating disk 41 and a second feeding mechanism respectively installed on the frame 1. A feeding pipe 42 connecting the two is provided between the second feeding mechanism and the second vibrating disk 41. The feeding pipe is made of a plastic hose.

The seventh driving member controls the vertical reciprocating movement of the second mounting base, so that the front end position of the second mounting base is close to or far from the material placing seat. The third driving member drives the push rod to perform horizontal reciprocating movement. The shaft head in the second vibrating disk enters the feeding port of the feeding channel from the feeding pipe. As Figure 7 shown, the shaft head falls into the material placing hole and is pushed by the push rod to the upper part of the discharging port, and then falls into the lower guide sleeve by gravity to wait for subsequent stamping work.

[0069] The stamping mechanism includes:
