[0030] Next, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0031] Rivet feeding device for riveting, such as Figure 1 , Figure 2 , including a device body 140 for rivet feeding; the device body 140 includes a feeding device 141 and a vibrating device 142; the feeding device 141 includes a feeding bin 1411 and a feeding pipe 1413; the vibrating device 142 includes a vibrating feeding port 1421 and a vibrating discharging port 1422; wherein,

[0032] The feed bin 1411 is used to hold a number of rivets; Figure 2 , Figure 3 As shown, in a preferred embodiment, the feed device 141 further includes a guide plate 1417; the guide plate 1417 is installed at the opening of the feed bin 1411, and is used to extend toward the opening of the feed bin 1411 to form a rivet feeding guide structure; a large number of rivets in batches enter the feed bin 1411 along the guide plate 1417, which effectively increases the rivet feeding amount, thereby reducing the number of feeding times. In this embodiment, the feed device 141 further includes a feed fixing seat 1415, which is used to support the feed bin 1411 and / or the feed pipe 1413.

[0033] like Figure 3 , Figure 4As shown, the feeding device 141 also includes a feeding mounting plate 1416; the feeding mounting plate 1416 is in the shape of a flat plate; the upper end of the feeding mounting plate 1416 is provided with a first mounting hole 14161 for mounting the feeding pipe 1413, and the lower end is provided with a mounting portion of the loading cylinder 14121, so that the loading push block 14122 reciprocates along the extension direction of the feeding mounting plate 1416.

[0034] One end of the feeding pipe 1413 is internally connected to the feeding bin 1411, and the other end is internally connected to the vibration loading port 1421; Figure 2-5 As shown, the feeding pipe 1413 is used to connect the feeding device 141 with the vibrating device 142. In this embodiment, the vibrating device 142 is a vibrating plate, which is fixed on a fixed base by inversion. The vibrating feeding port 1421 is located on one side of the lower part of the entire vibrating device 142, so that the rivets are fed by their own weight, thereby improving the feeding efficiency. It should be understood that the vibrating plate is a conventional feeding device for nail-like structures, which will not be described in detail here, and there should be no technical ambiguity or misunderstanding of the solution.

[0035] The end of the feeding pipe 1413 connected to the vibration feeding port 1421 is tilted downward; the rivets are sequentially passed through the feeding bin 1411 and the feeding pipe 1413 to the vibration feeding port 1421, and are vibrated and fed to the vibration discharge port 1422 by the vibration device 142. In a preferred embodiment, Figure 3-5 As shown, the feeding device 141 also includes a feeding rotation adjustment structure 1414; the feeding bin 1411 and / or the feeding pipe 1413 are connected to the feeding fixed seat 1415 through the feeding rotation adjustment structure 1414 to adjust the angle between the feeding bin 1411 and / or the feeding pipe 1413 and the horizontal plane. In this embodiment, the feeding rotation adjustment structure 1414 is a rotating connection seat and a rotating shaft fixed on the feeding mounting plate 1416, and one end of the rotating shaft is fixed on the feeding fixed seat 1415, so that the feeding bin 1411 and the feeding pipe 1413 can rotate around the rotating shaft, thereby adjusting the opening direction of the feeding bin 1411 and the inclination angle of the feeding pipe 1413 at the same time.

[0036] In a preferred embodiment, if Figure 3-5 As shown, the feeding device 141 further includes a feeding execution unit 1412, and the feeding execution unit 1412 is used to push the rivet into the feeding tube 1413 under the driving of external force. In this embodiment, the rivet is pushed into the feeding tube 1413 by the driving action of the feeding execution unit 1412, so that the rivet falls into the vibration device 142 along the feeding tube 1413.

[0037] like Figure 4As shown, the feeding execution unit 1412 includes a feeding cylinder 14121 and a feeding push block 14122; the feeding push block 14122 is connected to the push rod of the feeding cylinder 14121; the feeding cylinder 14121 drives the feeding push block 14122 to lift the rivet toward the inlet direction of the feeding pipe 1413. In this embodiment, the contact portion of the feeding push block 14122 for lifting the rivet is in a "V" shape, so that the relative number of rivets lifted each time is consistent. Preferably, in one embodiment, in order to further control the number of rivets pushed each time and prevent too many rivets from clogging the feed pipe 1413, the feeding push block 14122 is connected to the push rod of the feeding cylinder 14121 by an elastic structure. For example, a spring is used to connect the feeding push block 14122 and the feeding cylinder 14121. When there are too many rivets, the contact part of the feeding push block 14122 moves downward due to gravity, so that the cylinder moves the same stroke, and the number of rivets entering the feed pipe 1413 is reduced, thereby ensuring the continuity of feeding to a certain extent.

[0038] The rivet feeding device for riveting proposed by the present invention adopts gravity combined with vibration feeding to realize an efficient rivet feeding process. The present invention has an ingenious structure and a reasonable design, meets the actual needs of automated production, and is easy to promote and apply in the field of automation.
