[0002] Self-piercing rivet equipment is used for fastening and riveting of various metal plates, pipes and other manufacturing industries. It is widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration.

[0003] The rivet magazine mechanism in the existing self-piercing rivet equipment mainly includes a feed block, on which a main channel for storing rivets is provided. The upper end of the main channel is connected to a feed pipe, and the lower end of the main channel is provided with a hatch. When the main channel in the rivet magazine is storing materials, several rivets fly to the bottom of the main channel at high speed, and several rivets are stacked in sequence, which often causes the rivets to be stacked too tightly. When the hatch is opened to discharge the materials, the rivets may not fall down by their own gravity due to the tight stacking, resulting in a jamming failure and poor equipment operation stability.

The feed block 2 is provided with at least one main channel 20 for storing rivets 5. The top 200 of the main channel 20 is connected to a feed pipe 6. The first stopper 3 is arranged at the bottom 201 of the main channel 20. The first driving cylinder 4 is electrically connected to the controller 1 for driving the first stopper 3 to switch between a first position and a second position. When the first stopper 3 is in the first position, the first stopper 3 can block the rivets in the main channel 20. 5 falls. When the first stopper 3 is in the second position, the rivet 5 in the main channel 20 can fall and be discharged by its own gravity. The proximity sensor 7 is provided on the feeding pipe 6 and is electrically connected to the controller 1. The second stopper 8 is provided at the connection between the main channel 20 and the feeding pipe 6. The second driving cylinder 9 is electrically connected to the controller 1 and is used to drive the second stopper 8 to switch between the first position and the second position. When the second stopper 8 is in the first position, the second stopper 8 can prevent the rivet 5 in the feeding pipe 6 from entering the main channel 20. When the second stopper 8 is in the second position, the rivet 5 in the feeding pipe 6 can enter the main channel 20 by its own gravity.

[0026] The rivet magazine mechanism also includes an air vibrator 11 and a mounting block 12. The air vibrator 11 is arranged at the bottom 201 of the main channel 20 and is electrically connected to the controller 1 for driving the feeding block 2 to vibrate. One end of the mounting block 12 is fixedly connected to the feeding block 2, and the first driving cylinder 4 and the air vibrator 11 are both fixed at the other end of the mounting block 12.

[0027] The rivet magazine mechanism further includes an air blowing device 13 , which is electrically connected to the controller 1 and is used for blowing air toward the bottom 201 of the main channel 20 .

[0028] Specifically, the feed block 2 is further provided with a blowing hole 22 , one end of the blowing hole 22 is communicated with the main channel 20 , and the other end of the blowing hole 22 is connected to the blowing device 13 .

[0029] The feed block 2 is further provided with a first channel 23 , which is in communication with the main channel 20 . The first stopper 3 is at least partially accommodated in the first channel 23 , and the first stopper 3 can telescopically move along the direction of the first channel 23 .

[0030] The feed block 2 is further provided with a second channel 21 , which is connected to the main channel 20 . The second stopper 8 is at least partially accommodated in the second channel 21 , and the second stopper 8 can telescopically move along the direction of the second channel 21 .

[0031] The rivet magazine mechanism also includes a second mounting plate 10, one side of the second mounting plate 10 is fixed to the feed block 2, the second driving cylinder 9 is fixed to the other side of the second mounting plate 10, and the second stop block 8 passes through the second mounting plate 10 and is at least partially accommodated in the second channel 21.

[0032] The utility model also provides a self-piercing rivet device, comprising the above-mentioned rivet magazine mechanism.

[0033] During operation, a rivet 5 flies from the feed tube 6 to the top of the main channel 20 at high speed. At this point, the second stopper 8 is in the first position, preventing the rivet 5 in the feed tube 6 from entering the main channel 20. Simultaneously, when the rivet 5 passes the sensor 7 on the feed tube 6 at high speed, the second drive cylinder 9 delays its action and drives the second stopper 8 from the first position to the second position. This stops the rivet 5 flying at high speed and decelerates, allowing it to fall freely into the main channel 20. The second drive cylinder 9 then drives the second stopper 8 from the second position to the first position again, where it again blocks the next rivet 5. This reciprocating action continues until the number of rivets 5 in the main channel 20 reaches a predetermined number. When the number of rivets 5 in the rivet magazine reaches a predetermined number, the first drive cylinder 4 drives the first stopper 3 from the first position to the second position, retracting it from its original extended state. Simultaneously, the pneumatic vibrator 11 activates, causing the feed block 2 to vibrate, reducing the risk of rivets becoming stuck in the main channel 20. During the nail arrangement process, if the column magazine mechanism still has a nail jam, the blowing device 13 can be started to blow air into the blowing hole 22 to blow the rivets 5 in the main channel 20 upward, which is equivalent to loosening the tightly stacked rivets 5. After closing the blowing device 13, the air vibrator 11 continues to open to discharge the rivets 5.

[0034] The utility model has the following beneficial effects:

[0035] 1. By setting a second driving cylinder 9 to drive the second stopper 8 to hinder the high-speed movement of the rivet 5, the rivet 5 is stacked in the main channel 20 in a free-falling state, thereby avoiding the rivets 5 from being stacked too tightly, reducing the jamming failure rate, and improving the operation stability of the equipment.

[0036] 2. By arranging the air vibrator 11 to vibrate the feeding block 2, the failure rate of nail jamming is further reduced, and the stable operation of the equipment is maintained.

[0037] 3. By setting a blowing hole 22 at the bottom of the feed block 2, the blowing device 13 can blow gas from the blowing hole 22 into the main channel 20 to loosen the rivets 5 that are too tight, making it convenient to adjust the equipment after the rivets are stuck. The problem of the rivets being stuck can be solved without disassembly, which is convenient and quick.

[0038] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
