As shown in fig. 1-5, the automatic feeding mechanism for riveting the punch rivet nut comprises an upper tray 3, a feeding chute 4 and a storage tray 5, wherein the upper tray 3 comprises a disc 7 with a surrounding baffle 6 around, an elastic shifting sheet 8 driven by a first motor (not shown) to rotate is installed in the disc 7, the elastic shifting sheet 8 rotates around the axis of the disc 7, a strip-shaped through groove 9 is arranged at the bottom of the disc 7, one end of the strip-shaped through groove 9 points to the axis of the disc 7, the other end of the strip-shaped through groove 9 is communicated with the circumferential surface of the disc 7, an opening 10 is arranged on the surrounding baffle above the strip-shaped through groove 9, an air cylinder 11 is installed below the disc 7, a push sheet 12 is fixedly connected onto a piston rod of the air cylinder 11, the push sheet 12 can movably extend into the strip-shaped through groove 9, a piston rod of the air cylinder 11 is parallel to the length direction of the strip-shaped, an extension groove 14 for the push sheet 12 to move is formed between the guide rods 13, the storage tray 5 comprises a circular plate 16 driven by an indexing motor 15 to rotate, a plurality of straight rods 17 are vertically fixed on the surface of the circular plate 16, the straight rods 17 are arranged in a row around the axis circumference of the circular plate 16, the tail end of the extension groove 14 is close to a circle formed by the straight rods 17, and the height of the uppermost end of the straight rod 17 is lower than that of the extension groove 14. The punching riveting nut is placed in the disc 7, part of the punching riveting nut is in a state that the four-corner nut part 2 faces downwards, and the rest part of the punching riveting nut is in a state that the four-corner nut part 2 faces upwards. The first motor drives the elastic shifting sheet 8 to rotate, the elastic shifting sheet 8 pushes the riveting nuts in the disc 7 to do centrifugal motion, the four-corner nut parts 2 of the riveting nuts with the four-corner nut parts 2 facing downwards are clamped into the strip-shaped through grooves 9, and then the air cylinder 11 drives the pushing sheet 12 to push the riveting nuts in the strip-shaped through grooves 9 into the extension grooves 14 and drop from the tail ends of the extension grooves 14 one by one. The indexing motor 15 drives the circular plate 16 to rotate, so that one straight rod 17 stays below the tail end of the extension groove 14, the punching and riveting nuts falling from the tail end of the extension groove 14 are sleeved on the straight rod 17 and automatically slide to the lower end of the straight rod 17, the punching and riveting nuts are sequentially connected on the straight rod 17 from bottom to top, and the punching and riveting nuts on the straight rod all have accurate positions and face-to-face orientation. After the circular plate 16 rotates, the straight rod 17 filled with the rivet punching nuts stays at a designated position, and a robot can take off the rivet punching nuts from the straight rod 17 one by one to carry out feeding. The upward part of the four-corner nut part 2 is continuously adjusted in posture under the pushing of the elastic shifting piece 8, and the four-corner nut part 2 is embedded into the strip-shaped through groove 9 until the four-corner nut part 2 faces downward. The disc 7 can also vibrate by arranging a vibration motor, so that the posture of the rivet punching nut can be adjusted more conveniently.

Furthermore, the bottom of the disc 7 is provided with a convex strip 26, the convex strip 26 is tightly attached to the bottom of the disc 7, one end of the convex strip 26 points to the center of the disc 7, and the other end of the convex strip 26 points to the enclosure 6. When the elastic shifting piece 8 pushes the rivet punching nut to move in the disc 7, the square plate part 1 of the rivet punching nut with the four-corner nut part 2 upward is blocked by the raised line 26, so that the rivet punching nut can incline, most of the four-corner nut parts 2 of the rivet punching nut incline downward and continue to move in the disc 7, and the rivet punching nut moves to the elongated through groove 9 and is embedded into the elongated through groove 9, as shown in fig. 6-8. The clearance between the elastic pick 8 and the disc 7 is larger than the height of the convex strip 26, and the height of the convex strip 26 is equivalent to the thickness of the square plate part 1.
It should be noted that the technical features of the first motor, the index motor, the second motor, the cylinder, the vibration motor, etc. related to the present patent application should be regarded as the prior art, the specific structure and the operation principle of the technical features and the control mode and the spatial arrangement mode that may be related to the technical features should be adopted by the conventional selection in the field, and should not be regarded as the invention point of the present patent, and the present patent is not further specifically described in detail.
