The only difference is that the position of the rivet head 5 on each automatic riveting device is different. Then, multiple robots are set between the multiple automatic riveting devices to grab the aluminum frame beam riveted by an automatic riveting device and the steel nuts that need to be riveted. When in use, the manipulator puts the aluminum frame beam onto the riveting platform 6, drives the second cylinder 8 to work, drives the lifting seat 14 to move down, and allows the visual inspection camera 16 to take a picture of the aluminum frame beam on the riveting platform 6 first, and sends the photographic information to the controller 2.

If not, the manipulator can be driven later to adjust the aluminum frame beam to ensure that the rivet holes on the aluminum frame beam are aligned with the rivet head 5. If one The third cylinder 31 is driven to work first. According to the width of the aluminum frame beam, the left top block 10 is extended and slowly approaches the right top block 11 until the aluminum frame beam is clamped. Then the steel nut to be riveted is placed in the corresponding rivet hole of the aluminum frame beam. Then the first cylinder 3 is driven to work, so that the upper lifting plate 4 moves down quickly, and the rivet head 5 moves down to press the steel nut into the rivet hole corresponding to the aluminum frame beam. Then the rivet head 5 is driven to move up and reset. The riveting of this station is completed, and the robot (how to grab the aluminum frame beam and install it) is used. The installation and placement are all conventional technologies in this field, so they are not described in detail) and are grabbed to the next automatic riveting equipment for riveting until the riveting is completed. Therefore, the present structural setting can realize automatic riveting of the aluminum frame beam, and the aluminum frame beams of different widths can be positioned during the riveting process, thereby improving the versatility of the equipment. Moreover, compared with manual riveting, the present structure detects whether there is a position deviation of the aluminum frame beam before riveting by adding a visual detection camera 16, thereby making the final work efficiency higher, the error rate lower, and the product qualification rate higher.
