[0027] Please see Figure 1-6 As shown, this invention is a multi-station cyclic riveting device, including a support base 1 and a riveting device 7. The riveting device 7 is located at the rear top of the support base 1. The device also includes a transport mechanism 4 for transporting metal plates, a placement mechanism 2 for placing nuts on the metal plates, a detection mechanism 3 for detecting whether the riveting effect of the metal plates is qualified, and a delivery mechanism 5 for delivering the metal plates into the riveting device 7. The placement mechanism 2 and the detection mechanism 3 are respectively located on the top sides of the support base 1, and the transport mechanism 4 and the delivery mechanism 5 are both located on the top of the support base 1. The support base 1 is respectively equipped with a connection to the placement mechanism 4. The nut placement station, riveting station, and inspection station corresponding to structure 2, riveting device 7, and inspection mechanism 3 are each responsible for the operation of their respective stations, ensuring that each station can be operated independently by the corresponding mechanism or device. The transport mechanism 4 includes a rotating platform 401 for placing metal plates. Multiple sets of placement seats 402 are fixedly connected to the top of the rotating platform 401 at equal intervals. The workers place the metal plates to be riveted into the placement seats 402 in sequence, and the rotating platform 401 drives the metal plates to pass through the working areas of the placement mechanism 2, the delivery mechanism 5, and the inspection mechanism 3 in sequence.

[0028] In this invention, to achieve precise placement of the nut, the placement mechanism 2 includes a nut adsorption assembly 207 that cooperates with the rotating platform 401, and a first moving assembly for moving the nut adsorption assembly 207. The first moving assembly includes a first fixed bracket 201 fixedly connected to the support base 1, a first electric slide rail 202 connected to the first fixed bracket 201, and a first sliding bracket 204 connected to the first electric slide rail 202. The extension directions of the first electric slide rail 202 and the first sliding bracket 204 are perpendicular to each other. The first electric slide rail 202 can drive the first sliding bracket 204 to move. A second electric slide rail 203 is connected to a sliding bracket 204, and a second sliding bracket 208 is mounted on the second electric slide rail 203. The second electric slide rail 203 can move the second sliding bracket 208. A first electric telescopic cylinder 206 is fixedly connected to the second sliding bracket 208. A nut adsorption assembly 207 is fixedly connected to the output end of the first electric telescopic cylinder 206. The nut adsorption assembly 207 is equipped with a negative pressure component to facilitate the adsorption and fixation of the nut. The first electric telescopic cylinder 206 can move the nut adsorption assembly 207 downward, thereby facilitating the gripping and placement of the nut. A CCD detection device 205 is fixedly connected to the second sliding bracket 208. A controller electrically connected to the CCD detection device 205 is provided on one side of the support base 1. The CCD detection device 205 is used to detect whether the nut is placed correctly, so as to adjust the nut with a misaligned position in a timely manner.

[0029] In this invention, in order to achieve the effect of automatically adjusting the feeding state of the nuts, a nut feeding device 6 that cooperates with the nut adsorption assembly 207 is fixedly connected to the support base 1. The nut feeding device 6 is equipped with a vibrating plate for orienting and sorting the nuts. The vibrating plate can make the nuts discharge in an orderly manner by vibration. The nut feeding device 6 has a feeding port that cooperates with the vibrating plate. The nut adsorption assembly 207 picks up the nuts on the vibrating plate through the feeding port.

[0030] The rotating platform 401 includes a cam divider 4011 fixedly mounted on the support base 1, and a carrier plate 4012 cooperatingly mounted on the cam divider 4011. Placement seats 402 are all fixedly mounted on the carrier plate 4012. The cam divider 4011 can drive the carrier plate 4012 to rotate, thereby causing the metal plate inside the placement seat 402 to move. The carrier plate 4012 has a circular opening in the middle, and a central shaft 4013 fixedly connected to the support base 1 is disposed inside the circular opening. The central shaft 4013 is responsible for supporting the carrier plate 4012, and remains stationary during the rotation of the carrier plate 4012.

[0031] In this invention, to enable the feeding operation of the riveting device 7, the feeding mechanism 5 includes a third fixed bracket 501 fixedly connected to the central shaft 4013. A fifth electric slide rail 502 is connected to the third fixed bracket 501, and a fifth sliding bracket 503 is connected to the fifth electric slide rail 502. The fifth electric slide rail 502 can drive the fifth sliding bracket 503 to move. A third electric telescopic cylinder 505 is fixedly connected to one end of the fifth sliding bracket 503 near the riveting device 7. A second negative pressure suction plate 504 for transporting the metal plate is fixedly connected to the output end of the third electric telescopic cylinder 505. In use, the output end of the third electric telescopic cylinder 505 extends, causing the second negative pressure suction plate 504 to come close to the metal plate. Then, the output end of the third electric telescopic cylinder 505 retracts, causing the metal plate to detach from the rotating platform 401. Then, the fifth electric slide rail 502 drives the fifth sliding bracket 503 to move, thereby feeding the metal plate into the riveting device 7 to facilitate the riveting operation of the metal plate and the nut.

[0032] In this invention, to remove defective products, the inspection mechanism 3 includes a laser scanning sensor 306 for inspecting the riveted metal plate, a picking component for transporting defective products, and a second moving component for moving the laser scanning sensor 306 and the picking component. The second moving component includes a second fixed bracket 301 fixedly connected to the support base 1, a third electric slide rail 302 connected to the second fixed bracket 301, and a third sliding bracket 304 connected to the third electric slide rail 302. The extending directions of the third electric slide rail 302 and the third sliding bracket 304 are perpendicular to each other. The three electric slide rails 302 can drive the third sliding bracket 304 to move. A fourth electric slide rail 303 is connected to the third sliding bracket 304, and a fourth sliding bracket 305 is connected to the fourth electric slide rail 303. A laser scanning sensor 306 is fixedly connected to the fourth sliding bracket 305. The fourth electric slide rail 303 can drive the fourth sliding bracket 305 to move, thereby driving the laser scanning sensor 306 to scan the entire riveted metal plate and transmit the scanning results to the controller. The controller compares the detection data to detect the riveting effect of the metal plate. The picking component includes a second electric telescopic cylinder 307 fixedly connected to the bottom of the third sliding bracket 304. A first negative pressure suction plate 308 for transporting the metal plate is fixedly connected to the output end of the second electric telescopic cylinder 307. The second electric telescopic cylinder 307 can move the first negative pressure suction plate 308 downward, thereby facilitating the adsorption and transport of the metal plate. A receiving tray 8 is provided on one side of the support base 1 to cooperate with the first negative pressure suction plate 308. The receiving tray 8 is used to receive the metal plate transported by the first negative pressure suction plate 308 so that the first negative pressure suction plate 308 can perform the next adsorption operation.

[0033] The working principle of this invention is as follows: When in use, the operator places the metal plates in the placement seats 402 on the rotating platform 401 in sequence. The rotating platform 401 rotates and drives the metal plates into the nut placement station. At the same time, the vibrating plate inside the nut feeding device 6 vibrates to make the nuts be discharged in an orderly manner. The first electric slide rail 202 drives the first sliding bracket 204 to move, the second electric slide rail 203 drives the second sliding bracket 208 to move, and the first electric telescopic cylinder 206 extends, so that the nut adsorption component 207 can adsorb and fix the nut on the vibratory plate through the feeding port on the nut feeding device 6. Then the first electric telescopic cylinder 206 retracts, the first electric slide rail 202 drives the first sliding bracket 204 to move, and the second electric slide rail 203 drives the second sliding bracket 208 to move, so that the nut adsorption component 207 can transport the nut to the corresponding position above the metal plate. Then the first electric telescopic cylinder 206 extends and places the nut at the corresponding position on the metal plate. The nut adsorption component 207 stops adsorption. Then the placement effect is detected by the CCD detection device 205 and the detection result is transmitted to the controller for comparison, so that the nuts with positional deviations can be adjusted in time, thereby realizing the placement of the nut. The above operation is repeated until all nut placement points on the metal plate are filled with nuts.

[0034] The rotating platform 401 rotates, causing the metal plate to enter the riveting station. The third electric telescopic cylinder 505 extends, adsorbing and fixing the metal plate through the second negative pressure suction plate 504. Then, the third electric telescopic cylinder 505 retracts, causing the metal plate to detach from the rotating platform 401. The fifth electric slide rail 502 drives the fifth sliding bracket 503 forward, placing the metal plate above the riveting platform of the riveting device 7. Then, the third electric telescopic cylinder 505 extends, placing the metal plate on the riveting platform. The second negative pressure suction plate 504 stops adsorbing the metal plate. Then, the third electric telescopic cylinder 505 retracts, and the fifth electric slide rail 502 drives the fifth sliding bracket 503 forward, placing the metal plate above the riveting platform of the riveting device 7. The sliding rail 502 drives the fifth sliding bracket 503 to move backward, so that the riveting device 7 can rivet the metal plate and the nut. After the riveting is completed, the fifth electric sliding rail 502 drives the fifth sliding bracket 503 to move forward, and the third electric telescopic cylinder 505 extends, so that the second negative pressure suction plate 504 can adsorb and fix the metal plate. Then the third electric telescopic cylinder 505 retracts, the fifth electric sliding rail 502 drives the fifth sliding bracket 503 to move backward, and the third electric telescopic cylinder 505 extends, placing the metal plate on the rotating platform 401, thereby realizing the riveting operation of the metal plate.

[0035] The rotating platform 401 rotates, driving the metal plate into the inspection station. The third electric slide rail 302 moves the third sliding bracket 304, bringing the laser scanning sensor 306 closer to the metal plate. Then, the fourth electric slide rail 303 moves the fourth sliding bracket 305, which in turn moves the laser scanning sensor 306, allowing it to perform a lateral scan of the metal plate surface and transmit the scan results to the controller. The controller compares the data to determine the riveting effect of the metal plate. If it is determined to be a normal product, the rotating platform 401 continues to rotate, moving the metal plate to the manual unloading station for manual unloading. If... If the product is determined to be defective, the third electric slide rail 302 moves the third sliding bracket 304 to transport the first negative pressure suction plate 308 above the metal plate. The second electric telescopic cylinder 307 extends to allow the first negative pressure suction plate 308 to come close to the metal plate and fix it in place. Then, the second electric telescopic cylinder 307 retracts, and the third electric slide rail 302 moves the third sliding bracket 304 backward to transport the metal plate above the receiving tray 8. The second electric telescopic cylinder 307 extends to place the metal plate inside the receiving tray 8. Then, the first negative pressure suction plate 308 and the laser scanning sensor 306 reset, and continue to wait for the next set of metal plates to enter the inspection station, thus completing the inspection of the riveting effect.
