Cartridge-type rivet feeding mechanism of flow drill screwing device

A cartridge-type rivet feeding mechanism of a flow drill screwing device comprising:

• a rivet box configured for providing rivets to a riveter head;
• a magazine configured for storing rivets from the rivet box, and comprising a magazine cover plate arranged at a feeding end and a first air inlet communicating with the magazine, wherein a rivet feeding mechanism is detachably connected with an outer side of the magazine cover plate;
• a first connecting tube communicating with a discharge port of the magazine;
• a rivet pulling mechanism comprising a rivet pulling block, a rivet pulling block guiding housing and a linear driving unit connected with the rivet pulling block, wherein an inlet of the rivet pulling block guiding housing is communicating with the first connecting tube, an outlet of the rivet pulling block guiding housing is connected with a second connecting tube, the rivet pulling block is capable of accommodating a rivet and is configured for transferring the rivet from the first connecting tube to the second connecting tube;
• and
• a blowing mechanism comprising a curved connecting tube and a third air inlet defined on the curved connecting tube, wherein an upper end of the curved connecting tube is connected with the second connecting tube, a lower end of the curved connecting tube is horizontally arranged and fixedly connected with the riveter head of the flow drill screwing device, and the third air inlet is arranged on the lower end of the curved connecting tube and is configured for pushing the rivet to the riveter head;
• wherein, the rivet pulling block guiding housing is defined with a second air inlet opposite to the second connecting tube;
• the first air inlet is configured for compressed air to enter the first connecting tube to push the rivet to move towards the rivet pulling mechanism and the second air inlet is configured for compressed air to enter the second connecting tube to push the rivet to move towards the riveter head.
