Description

Technical Field

[0001] This utility model relates to the field of riveting technology, specifically to an automatic rivet placement riveting structure. Background Technology

[0002] Riveting is a common process on existing sheet metal, electronic, or automotive parts production lines. A typical workflow involves the operator stopping the press, manually moving the sheet metal part to be riveted to the lower die of the press, picking up a single rivet from the material box or simple vibratory feeder, visually aligning it with the rivet hole on the sheet metal part, and inserting it. After confirming the position is correct, the press is restarted to complete one riveting operation. If the product has multiple rivet points, the "stop—manual rivet placement—re-pressing" steps must be repeated multiple times. This process is relatively cumbersome, and manual rivet placement is inefficient, with the cycle time heavily influenced by the operator's skill level, making it difficult to match the efficiency of high-speed presses. Furthermore, manual visual positioning has significant errors, leading to rivets being easily tilted or missed, resulting in poor consistency in riveting strength and a high scrap rate. Utility Model Content

[0013] In a preferred embodiment of this utility model, the bracket includes a support plate and a support leg. One end of the support plate rests flat on the stamping table of the punch press, and the support leg is located at the other end of the support plate. The support leg supports the front end of the support plate, and the rear end of the support plate rests directly on the existing stamping table of the punch press. The rigidity of the punch press itself serves as the rear support point of the support plate, resulting in a simple structure and good stability.

[0014] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonable. The robot arm uses a suction and release tool to pick up the workpiece located on the tray and transfer it to the slide. Then, the robot arm uses the suction and release tool to pick up the rivets provided by the rivet feeder and place them on the rivet hole of the workpiece. Then, the slide is pushed to the punching position of the punch press, and the punch press is started to perform a pressing action to complete the punching and riveting process. Finally, the robot arm uses the suction and release tool to pick up the workpiece that has completed the riveting process and put it back on the tray, realizing the purpose of automatic rivet placement and riveting, replacing the traditional manual rivet placement process, effectively reducing labor intensity, improving work efficiency, and the robot arm has high repeatability and positioning accuracy, so that the rivets are no longer tilted or missed, ensuring the riveting quality and significantly reducing the scrap rate.
