[0021] Example

[0022] In order to solve the problem that the rivet feeding mechanism in the prior art is difficult to continuously and stably feed the double-station riveting machine 70 based on visual positioning disclosed by our company, reference Figure 1-Figure 2 As shown, the present application discloses a rivet feeding mechanism, including a machine platform 10 and rivet feeders 20 arranged on the machine platform 10 in sequence along a set direction (the specific structure of the rivet feeder 20 is a known technology, and the operator can adapt to the selection in actual use), an alternating material handling mechanism 30 and an air blowing feeding mechanism 40;

[0023] The alternating material handling mechanism 30 includes a rotating drive assembly 31, a mounting plate 32, two lifting drive assemblies 34 and two material suction assemblies 35. The rotating drive assembly 31 is fixed on the machine platform 10. The mounting plate 32 is connected to the driving portion of the rotating drive assembly 31 and extends the rotating drive assembly 31 on opposite sides thereof. The two lifting drive assemblies 34 are respectively vertically mounted above the opposite sides of the mounting plate 32. The two material suction assemblies 35 are respectively connected to the driving portions of the two lifting drive assemblies 34.

[0024] The air blowing feeding mechanism 40 includes a feeding platform 41, which is arranged above the machine platform 10. A blanking through hole 411 is vertically opened inside the feeding platform 41. The blanking through hole 411 is connected to a rivet gun through a feeding pipeline (the feeding pipeline and the rivet gun are not shown). A blowing hole 412 communicating with the blanking through hole 411 is opened on either side of the feeding platform 41. The blowing hole 412 is connected to an air pump through a blowing pipeline (the air outlet pipeline and the blowing pump are not shown).

[0025] refer to Figure 3 As shown, in the specific implementation process, the rotating drive component 31 drives the mounting plate 32 to rotate 180°. After the mounting plate 32 completes the rotation action, one of the lifting drive components 34 can drive the suction component 35 to descend. The suction component 35 absorbs a rivet from the rivet feeder 20, and the other lifting drive component 34 can place the previously absorbed rivet into the blanking slot of the loading platform 41 and blow it into the rivet gun by the blowing pump. Such continuous operation can stably feed rivets to the corresponding riveting machine 70.

[0026] In some embodiments, the rotary drive assembly 31 uses a rotary drive cylinder, and the rotary drive cylinder drives the mounting plate 32 to rotate at an angle of 180 degrees each time. In specific use, if other types of rotary drive assemblies 31 can also drive the mounting plate 32 of the present application to rotate 180 degrees, then personnel in this technical field can also choose to adapt.

[0027] In some embodiments, both lifting drive components 34 can use lifting drive cylinders, and first vertical plates 33 are respectively arranged above the opposite sides of the mounting plate 32. The two lifting drive cylinders are respectively arranged above the opposite sides of the two first vertical plates 33. The two suction components 35 are respectively connected to the piston rods of the two lifting drive cylinders. Under the drive of the two lifting drive cylinders, the two suction components 35 will descend synchronously, one of the suction components 35 will suck up a rivet from the rivet feeder 20, and the other suction component 35 will place the previously sucked rivet into the blanking groove.

[0028] In some embodiments, the two suction components 35 are both pneumatic suction nozzles. Guide rails 36 are vertically arranged on the opposite sides of the two first vertical plates 33 below the lifting drive cylinder. The two pneumatic suction nozzles are respectively slidably connected to the two guide rails 36. Under the drive of the lifting drive cylinder, the two pneumatic suction nozzles will slide on the guide rails 36 respectively, ensuring the stability of the pneumatic suction nozzles in sucking and discharging materials.

[0029] In order to make the loading platform 41 flush with the surface of the rivet feeder 20 , the present application connects the loading platform 41 to the machine 10 via at least two pad plates 42 at the bottom.

[0030] In addition to the above structure, the present application also includes a second vertical plate 50 and a detection sensor 60. The second vertical plate 50 is arranged on one side of the air blowing feeding mechanism 40 according to the set direction, and the detection sensor 60 is arranged on the side of the second vertical plate 50 facing the suction mechanism. When the detection sensor 60 detects that one of the first vertical plates 33 is in place, it will control the two lifting drive cylinders to drive the two pneumatic suction nozzles to descend respectively.
