When the laser beam sensor for detecting the material detects that there is material on the detection path, the vibration plate 51 in the first station 3 is started, and the vibration plate 51 brings the rivet into the extension path, and then it is inserted into the profiling groove in the clamping plate 73 through the extension path.

Then, the fixture transport lifting cylinder 112 is started to drive the positioning fixture 6 to rise and fall, and then the fixture transport translation assembly 111 is started to drive the fixture transport lifting cylinder 112 to move toward the two outer assembly lines 2, and then the positioning fixture 6 moves together.
