[0027] See Figures 1-3, this embodiment provides a rivet feeding device, which includes a vibrating disc 10. A section of material channel 101 is provided at the discharging end of the vibrating disc 10. A positioning component 11 is provided at the end of the material channel 101, which is used to move the rivets at the end of the material channel to a specified position on one side. A grasping component 12 is provided above the positioning component 11, and the grasping component 12 is driven to move by a lifting component 13 and a transverse movement component 14.

[0028] Specifically, the positioning component 11 includes a positioning platform 111. A guide rail 112 is provided on the positioning platform 111. Two groups of vertical plates 113 are provided on the positioning platform at both ends of the guide rail 112. A positioning cylinder 114 is provided on one group of vertical plates 113. A positioning plate 115 is provided at the output end of the positioning cylinder. A positioning groove 116 is inwardly opened along the top end and the side wall of the positioning plate 115. A baffle 118 is provided on the positioning platform on one side of the positioning groove 116.

[0029] In order to detect whether there is a rivet in the positioning groove 116, a detection sensor 117 is provided on the positioning plate 115. The detection sensor 117 penetrates through the vertical plate from the other side of the positioning groove and is aligned with the positioning groove 116. At the same time, in order to accurately position the position of the positioning groove after driving the rivet to move, limit rods 119 are respectively provided on the two groups of vertical plates 113 for abutting against the positioning plate 115.

[0030] Specifically, the grasping component 12 includes a grasping cylinder 121. A clamping jaw 122 is provided at the output end of the grasping cylinder 121. A clamping groove 123 adapted to the shape of the rivet is opened on the clamping jaw 122. The clamping jaw 122 can move to directly above the positioning groove 116 in the initial position.

[0031] In order to drive the clamping jaw to move horizontally and vertically, the lifting component 13 includes a lifting cylinder 131. A lifting plate 132 is provided at the output end of the lifting cylinder 131. The transverse movement component 14 includes a transverse movement cylinder 142. The transverse movement cylinder 142 is connected to the lifting plate 132 through a connecting plate 141. A transverse movement plate 143 is provided at the output end of the transverse movement cylinder 142. The transverse movement plate 143 and the lifting plate 132 form a sliding connection, that is, a sliding groove is opened on the lifting plate, and the transverse movement plate 143 is arranged in the sliding groove. The grasping cylinder 121 is provided at the end of the transverse movement plate 143.

[0032] Similarly, since both the lifting component 13 and the transverse movement component 14 are moving structures, limit rods are provided on both the lifting plate and the transverse movement plate to limit the moving positions of the two.

[0033] Working principle: The vibrating disk 10 drives the rivets to discharge and then moves to the end of the material channel 101. The height of the material channel 101 is not higher than the upper end face height of the positioning plate to block the rivets. Then, the positioning cylinder 114 drives the positioning plate 115 to move forward, and the positioning groove 116 moves to the outlet position of the material channel. The rivets enter the positioning groove 116, and the positioning cylinder resets. Subsequently, the lifting cylinder 131 is activated to drive the clamping jaw 123 to descend to the positioning groove position. The gripping cylinder 121 is activated to drive the clamping jaw 122 to open and then grip the rivets. The lifting cylinder drives the clamping jaw to rise. Finally, the transverse movement cylinder 142 is activated to drive the rivets to move to the riveting position, put down the rivets and then reset.

[0034] Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
