[0024] See also Figure 1-Figure 4As shown, the utility model provides a technical solution: an automatic feeding device for riveting rivets, an automatic feeding device for riveting rivets, comprising a workbench 1, a feeding pipe 7, a cylinder 9 and a flap mechanism 12, the outer wall of the workbench 1 is fixedly connected with the feeding pipe 7, the outer wall of the workbench 1 is fixedly connected with the cylinder 9, the outer wall of one end of the cylinder 9 is fixedly connected with a connecting plate 10, and the outer wall of the connecting plate 10 is provided with a flap mechanism 12;

[0025] The flap mechanism 12 includes a torsion spring 1201, a connecting column 1202, a rotating shaft 1203, a flap 1204 and a positioning groove 1205. The torsion spring 1201 is fixedly connected to the inner wall of the connecting plate 10, and one end of the torsion spring 1201 is fixedly connected to the connecting column 1202. The rotating shaft 1203 is fixedly connected to the outer wall of one end of the connecting column 1202, and the outer wall of the rotating shaft 1203 is fixedly connected to the connecting plate 10. The flap 1204 is fixedly connected to the outer wall of one end of the connecting column 1202, and a positioning groove 1205 is provided on the outer wall of one end of the flap 1204. First, the bolt 3 is passed through the fixing block 4 into the threaded hole 2, and the bolt 3 is continuously rotated so that the bolt 3 squeezes the fixing block 4 and the workbench 1, thereby fixing the fixing block 4 on the outer surface of the workbench 1, and then the fixing block 4 is fixed to the outer surface of the workbench 1. The fixing hole 5 fixes the device on the riveting device, and then the screw is transported to the surface of the positioning groove 1205 on the outside of the flap 1204 through the vibrating plate, the feeding pipe 7 and the feeding hole 6, and then the cylinder 9 is started to push the connecting plate 10 to push the screw to the bottom of the upper mold. The upper mold has a vacuum suction function. When the upper mold is pressed down and contacts the top of the screw flange, the vacuum suction sucks the screw and moves the screw downward. At the same time, when the upper mold contacts the flap 1204, the force of the flap 1204 drives the connecting column 1202 to rotate around the center of the torsion spring 1201 through the rotating shaft 1203, thereby avoiding the upper mold. The upper mold continues to press down until the riveting is completed. After the riveting is completed, the upper mold rises and leaves the surface of the flap 1204, and the torque generated by the rotation of the torsion spring 1201 pulls the flap 1204 back to its initial position.

[0026] In this embodiment, the fixing block 4 is threadedly connected to the workbench 1 through bolts 3, and multiple groups of threaded holes 2 are arranged on the outer wall of the workbench 1. The bolts 3 pass through the fixing block 4 and enter the inside of the threaded holes 2 to complete the connection between the fixing block 4 and the workbench 1. At the same time, multiple groups of threaded holes 2 and bolts 3 can improve the stability of the workbench 1 and the fixing block 4 after connection.

[0027] In this embodiment, the connecting plate 10 forms a telescopic structure with the workbench 1 through the cylinder 9. The cylinder 9 is symmetrically arranged with respect to the central axis of the workbench 1. By pushing the connecting plate 10 simultaneously with two cylinders 9, the stability of the connecting plate 10 during movement can be improved.

[0028] In this embodiment, the connecting plate 10 is slidably connected to the slide groove 8 through a slider 11. The slide groove 8 is symmetrically arranged with respect to the central axis of the workbench 1. The connection between the slide groove 8 and the slider 11 can provide a pulling force to the connecting plate 10, so that the connecting plate 10 always keeps a balance with the workbench 1, thereby preventing the connecting plate 10 from sinking due to its own weight when the cylinder 9 pushes the connecting plate 10, thereby affecting the positioning work of the device on the screws.

[0029] In this embodiment, the connecting column 1202 is rotatably connected to the connecting plate 10 via a rotating shaft 1203. The rotating shaft 1203 is symmetrically arranged with respect to the central axis of the connecting column 1202. The two rotating shafts 1203 are respectively fixed at both ends of the connecting column 1202, thereby improving the stability of the connecting column 1202 in rotating inside the connecting plate 10.

[0030] In this embodiment, the flap 1204 is rotatably connected to the connecting plate 10 via a connecting column 1202. The flap 1204 is symmetrically arranged with respect to the central axis of the connecting plate 10. By closing the two flaps 1204 to each other, the two positioning grooves 1205 are merged into a hole shape, so that the screws can be stably fixed on the surface of the flap 1204.

[0031] Working principle: First, pass the bolt 3 through the fixing block 4 into the threaded hole 2, and continue to rotate the bolt 3 so that the bolt 3 squeezes the fixing block 4 and the workbench 1, thereby fixing the fixing block 4 on the outer surface of the workbench 1, and then fix the device on the riveting device through the fixing hole 5 on the surface of the fixing block 4. After that, the screw will be transported to the surface of the positioning groove 1205 on the outer side of the flap 1204 through the vibrating plate through the feeding pipe 7 and the feeding hole 6, and then start the cylinder 9 to push the connecting plate 10 to push the screw to the bottom of the upper mold. The upper mold has a vacuum suction function, and the upper mold is pressed down with the screw method. When the top of the flange contacts, the vacuum suction sucks the screw and moves it downward. At the same time, when the upper mold contacts the flap 1204, the force on the flap 1204 drives the connecting column 1202 to rotate around the center of the torsion spring 1201 through the rotating shaft 1203, thereby avoiding the upper mold. The upper mold continues to press down until the riveting is completed. After the riveting is completed, the upper mold rises and leaves the surface of the flap 1204, and the torque generated by the rotation of the torsion spring 1201 pulls the flap 1204 back to its initial position. In this way, the use process of an automatic riveting rivet feeding device is completed.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
