[0052] In the embodiments of the present application, reference is made to Figures 1 to 4 and Figure 8The rivet transfer mechanism comprises a sliding assembly 10 and a loading assembly 20, the loading assembly 20 comprises a fixing frame 21 and a rivet clamping structure 22, the fixing frame 21 is arranged on the sliding assembly 10 to drive the fixing frame 21 to move with the sliding assembly 10, the rivet clamping structure 22 is rotationally connected to the fixing frame 21, the rivet clamping structure 22 is provided with a plurality of rivet clamping positions 22a, each rivet clamping position 22a is used for clamping a rivet, the loading assembly 20 has a horizontal state and a vertical state, when in the horizontal state, the rivet clamping structure 22 is arranged in parallel with the fixing frame 21 to block the plurality of rivet clamping positions 22a by the fixing frame 21, when in the vertical state, the rivet clamping structure 22 is arranged perpendicularly to the fixing frame 21 to arrange the fixing frame 21 and the plurality of rivet clamping positions 22a in a spaced manner.

[0053] The existing riveting machine generally sets a mechanical hand to grab the rivets from the rivet feeding mechanism, and then transfers the rivets to the position for riveting, the volume of the mechanical hand is relatively large, and in order to realize the grabbing action and the moving action, the mechanical hand also occupies a large operation space in the operation process, thus directly greatly increasing the volume of the entire riveting machine, therefore, the rivet transfer mechanism comprising the sliding assembly 10 and the loading assembly 20 is arranged to replace the mechanical hand.

[0054] Specifically, the sliding assembly 10 drives the fixing frame 21 of the loading assembly 20 to move to the position for feeding the rivets, and then controls the rivet clamping structure 22 to rotate to be perpendicular to the fixing frame 21, that is, the loading assembly 20 is in the vertical state, at this time, the fixing frame 21 and the plurality of rivet clamping positions 22a are arranged in a spaced manner and do not block the plurality of rivet clamping positions 22a, the rivet feeding mechanism can clamp the plurality of rivets into the plurality of rivet clamping positions 22a one by one to transfer the plurality of rivets to the rivet clamping structure 22, then the rivet clamping structure 22 of the loading assembly 20 is controlled to rotate until the rivet clamping structure 22 is horizontal to the fixing frame 21, that is, the loading assembly 20 is in the horizontal state, at this time, the fixing frame 21 blocks the plurality of rivet clamping positions 22a, so that the plurality of rivets can be temporarily stored in the plurality of rivet clamping positions 22a through the fixing frame 21, then the sliding assembly 10 continues to drive the fixing frame 21 to move to the position for riveting, and then controls the rivet clamping structure 22 to rotate relative to the fixing frame 21 until the rivet clamping structure 22 rotates to be perpendicular to the fixing frame 21, at this time, the fixing frame 21 and the plurality of rivet clamping positions 22a are arranged in a spaced manner and do not block the plurality of rivet clamping positions 22a, at this time, the plurality of rivets in the plurality of rivet clamping positions 22a can be ejected by manual or automatic feeding mode, so that the rivets are ejected from the rivet clamping positions 22a, and then the rivet transfer work is completed.

[0055] From the above entire operation process, the sliding assembly 10 replaces the running action of the mechanical hand, and the loading assembly 20 replaces the rotating action of the mechanical hand by switching between the horizontal state and the vertical state, so that the rivet transfer mechanism not only realizes the transfer and movement of the rivet, but also occupies smaller installation space and operation space compared with the mechanical hand, thereby reducing the volume of the riveting machine.

[0056] In an embodiment, referring to Figures 1 to 5 , the loading assembly 20 further comprises a rotating shaft 23 and a first driving cylinder 24, both ends of the rotating shaft 23 are rotatably connected to the fixed frame 21, the circumference of the rotating shaft 23 is connected with the rivet structure 22, and the circumference of the rotating shaft 23 is provided with a connecting piece 23a; the telescopic rod of the first driving cylinder 24 is rotatably connected with the connecting piece 23a and is arranged in a spaced manner with the rivet structure 22; wherein the first driving cylinder 24 drives the connecting piece 23a to rotate, so that the rotating shaft 23 drives the rivet structure 22 to rotate.

In this embodiment, the first driving cylinder 24 and the rotating shaft 23 are arranged to realize the independent rotation of the rivet structure 22, so that the rotation angle of the rivet structure 22 is more accurate.

[0058] When the telescopic rod of the first driving cylinder 24 is extended, the connecting piece 23a can rotate relative to the telescopic rod of the first driving cylinder 24, the connecting piece 23a can drive the rotating shaft 23 and the rivet structure 22 to rotate, until the rivet structure 22 is rotated to abut against the limiting plate 213, the plurality of rivet positions 22a of the rivet structure 22 can be blocked by the limiting plate 213, so that the plurality of rivets can be temporarily stored in the plurality of rivet positions 22a of the rivet structure 22.
