[0021] In this embodiment, the product is positioned in the product limiting cavity 211, and the riveting power member 31 drives the riveting member 32 through the riveting through-hole 212 to enter the product limiting cavity 211, thereby riveting the product, and then the electrical connection cover of the product and the shell are riveted together, which can effectively prevent the electrical connection cover from falling off after frequent plugging and unplugging of the product, thereby improving the service life of the product, and the automatic riveting method of the riveting mechanism can improve the riveting efficiency. Specifically, in the previous process, the electrical connection cover (i.e., the charging interface shell cover in the background technology) and the battery shell (i.e., the battery shell) are pre-assembled. When riveting, the product is placed in the product limiting cavity 211, so that the connection position of the battery shell and the electrical connection cover is opposite to the riveting through-hole 212, and then the riveting power member 31 drives the riveting member 32 through the riveting through-hole 212 and acts on the connection position of the battery shell and the electrical connection cover, so that the two are riveted together, thereby fixing the electrical connection cover and the battery shell.

[0022] In a specific embodiment, the frame 1 includes a box frame 111 and a base 112 and a mounting plate 113 located at the upper and lower ends of the box frame 111; the box frame 111, the base 112 and the mounting plate 113 enclose a feed cavity 114; the riveting mechanism and the limiting mechanism are installed on the mounting plate 113; the mounting plate 113 is provided with a connecting hole connecting the product limiting cavity 211 and the feed cavity 114; the riveting mechanism also includes an unlocking component 33 for opening or closing the connecting hole. In this embodiment, by being provided in the feed cavity The connecting hole connected to 114 allows the product to fall into the blanking cavity 114 through the connecting hole after riveting, thereby improving the riveting efficiency (if the connecting hole is not provided, the product needs to be taken out of the product limiting cavity 211 after riveting and then put back into the product to be riveted, which is inefficient). Specifically, the unlocking component 33 closes the connecting hole. At this time, the product is supported by the unlocking component 33 after being placed in. After riveting, the unlocking component 33 opens the connecting hole, allowing the product to fall into the blanking cavity 114, and then the connecting hole is reclosed to support the product to be riveted.
