The utility model discloses an automatic stringing mechanism for rapid rivets. The automatic stringing mechanism comprises a rack. A vibrating feeder is installed on the rack and connected with a stringing device through a conveying device, and the stringing device is used for stringing the rapid rivets and comprises a motor and a fixing shell which are fixedly installed on the rack. A rotating shaft of the motor is horizontally arranged. A feeding port through which the rapid rivets drop in and a discharging port through which the rapid rivets drop out are formed in the top and the bottom of the fixing shell respectively. A rotating limiting frame is arranged inside the fixing shell and driven by the rotating shaft of the motor to rotate, a plurality of limiting grooves used for containing the rapid rivets dropping in through the feeding port are formed in the rotating limiting frame in the circumferential direction, and stringing needles used for stringing the rapid rivets are arranged in the limiting grooves of the rotating limiting frame respectively. The automatic stringing mechanism strings the rapid rivets in arrays through gravity, performs feeding and discharging synchronously and works continuously and periodically, so that the speed of stringing the rapid rivets is greatly increased, and the working efficiency is significantly improved.
