[0081] H-type bracket 120, with A station and B station at its two ends respectively, and the output shaft of the positioner motor 110 is connected and fixed to the middle of the H-type bracket 120 to drive the H-type bracket 120 to rotate on the horizontal plane.

[0082] Two rotating brackets 130 are rotatably connected at both ends of each rotating bracket 130 to the end of its corresponding H-shaped bracket 120, and a fixture plate 300 is mounted on the rotating bracket 130.

[0085] like Figure 1 As shown, it also includes a rivet feeder 500 for feeding rivet nuts 600 to the rivet gun 220. There are two rivet feeders 500, each corresponding to the rivet device 200.

[0086] like Figures 6 to 9 As shown, the rivet feeder 500 includes:

[0089] The rivet transfer assembly 530 is used to transfer the rivet nut 600 at the end of the linear vibrating section 521 to the material handling station.

[0090] like Figures 7 to 9 As shown, the rivet transfer assembly 530 includes:

[0091] The receiving bracket 531 is fixedly installed at the outlet of the vertical vibration section 521, and the outlet of the vertical vibration section 521 is the material picking station;

[0092] The receiving platform 532 is slidably mounted on the upper surface of the receiving bracket 531 through the cooperation of the second sliding rail and the second slider. A material trough 533 is provided on the side facing the vertical vibration unit 521. The material trough 533 is through from top to bottom and has an opening on one side. The opening side of the material trough 533 can be connected to the outlet of the vertical vibration unit 521.

[0093] The translation cylinder 534 is fixedly installed on the receiving bracket 531. Its telescopic shaft is connected and fixed to the receiving platform 532, and drives the receiving platform 532 to move back and forth between the material picking station and the material loading station along the direction of the second sliding track.

[0094] The clamping rod 535 is installed at the loading station, corresponding to the opening side of the material trough 533. The end of the clamping rod 535 is a V-shaped groove 539. The clamping rod 535 is driven by the clamping cylinder 536 and can move to the material trough 533 that has been moved to the loading station, and then clamp the rivet nut 600. The clamping cylinder 536 is fixedly installed on the receiving bracket 531.

[0095] like Figure 7 As shown, a first sensor 537 is provided on the receiving platform 532. The first sensor 537 is used to sense whether there is material in the material trough 533.

[0096] A second sensor 538 is provided on the receiving bracket 531. The second sensor 538 is used to sense whether there is material on the rivet rod of the rivet gun 220.

[0097] A third sensor 5310 is installed on the loading station of the receiving bracket 531 to sense whether the receiving platform 532 has been moved to the loading station.

[0098] To ensure the safety of the operation, a protective net can be installed around the automatic riveting equipment of the frame, and a safety light curtain can be installed at the entrance of the protective net to protect the safety of the operators.

[0099] The working principle of this embodiment is as follows:

[0100] The operator enters the safety net and installs the frame workpiece 700 on station A of the H-type bracket 120, specifically on the fixture plate 300 at station A. Then, the operator exits the safety net and activates the switch. Part of the bottom positioning component 410 of the fixture plate 300 at station A activates, and the bottom cylinder 412 drives the pin 411 to rise and insert into the pin hole of the frame workpiece 700. Part of the pressing component 420 activates, and the pressing cylinder 422 drives the pressing plate 421 to move downwards, pressing down on the top of the frame workpiece 700. If the pressing plate 421 with the limit groove 423 presses down, it will press firmly against the inner wall and top surface of the frame workpiece 700. The displacement cylinder 438 drives the hole limiting cylinder 432 to move to the first position along the first sliding track 436. The telescopic axis of the hole limiting cylinder 432 is pushed upward, and the lower end of each pressing link 433 is forced to move upward. Since the middle part of the pressing link 433 is rotatably connected by the connecting rod 434, during the upward movement, the free ends of the two pressing links 433 will rotate downward with the rotating shaft 435 respectively, until the free ends of the two pressing links 433 press against the opposite ends of the upper peripheral surface of the workpiece hole 710, and finally press and fix the frame workpiece 700.

[0101] If riveting is performed on a frame workpiece 700 with workpiece hole 710 of other sizes and specifications, the bottom positioning component 410 of another part and the pressing component 420 of another part will be activated, and the displacement cylinder 438 will move the hole limiting cylinder 432 along the first sliding track 436 to the second position, thereby pressing and positioning the bottom, top and workpiece hole 710 of the frame workpiece 700 respectively.

[0102] After the frame workpiece 700 is positioned at station A, the positioner motor 110 of the positioner 100 starts, driving the H-shaped bracket 120 to rotate 180° until the frame workpiece 700 at station A is under the two riveting devices 200. Station B rotates to the safety light curtain, and the vision camera 230 of each riveting device 200 takes pictures to position the riveting location. The six-axis robot arm 210 drives the riveting gun 220 to perform the riveting operation on the frame workpiece 700. The two riveting devices 200 work synchronously, which is highly efficient. After the first side is riveted, the end motor 140 drives the rotating bracket 130 to rotate around its rotation axis, and the second side to be riveted rotates to be under the two riveting devices 200. This continues until all the working surfaces to be riveted are completed. Then, the riveted workpiece at station A is rotated back to its original position and unloaded by the operator or robot. While station A of the H-shaped bracket 120 is riveting, station B continues to have the frame workpiece 700 loaded by the operator or robot.

[0103] The rivet nuts 600 are fed one by one from the rivet gun 220 to the rivet feeder 500. The hopper 510 feeds the rivet nuts 600 to the vibratory feeder 520. The vertical vibration unit 521 moves the rivet nuts 600 one by one to the outlet, which is the material feeding station. The receiving platform 532 is pre-driven by the translation cylinder 534 to the position where it connects with the outlet of the vertical vibration unit 521. After the material trough 533 receives a rivet nut 600, the first sensor 5... 37 Once material is detected in the material trough 533, the translation cylinder 534 drives it to move to the loading station. Once it reaches the loading station, the third sensor 5310 senses it, and the clamping cylinder 536 drives the clamping rod 535 to move towards the material trough 533. The V-groove 539 presses the rivet nut 600 against the material trough 533 of the loading station until the rivet rod of the rivet gun 220 picks up the material, and the clamping rod 535 releases the rivet nut 600.

[0104] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it. They should not be used to limit the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
