[0042] The loading assembly 61 is rotatably disposed in the frame opening 23, and the loading assembly 61 includes a power gear 33 and a loading plate 38 which are stacked;

[0043] The transmission member 58 is slidably disposed in the frame opening 23, and the transmission member 58 is meshed with the teeth of the power gear 33. The force transmission pin 32 drives the transmission member 58 to move laterally to drive the power gear 33 to rotate, so that the loading plate 38 rotates to load the material;

[0044] The anti-backward assembly 63 is installed in the frame opening 23 and abuts against the transmission gear 33 . During the resetting process of the transmission member 58 , the anti-backward assembly 63 prevents the power gear 33 from rotating in the reverse direction.

[0045] Specifically, the stamping device drives the upper mold and the lower mold to close the mold, and the upper mold drives the riveting punch 31 and the force transmission pin 32 to move downward. The force transmission pin 32 first cooperates with the transmission member 58 to drive the transmission member 58 to move sideways, thereby driving the loading plate 38 to rotate to realize loading; so that the riveting position 52 of the product material strip 37 corresponds to the stud 51, and then the riveting punch 31 rivets the stud 51 on the riveting position 52; when the mold is opened, during the resetting process of the transmission member 58, the anti-backward component 63 remains in contact with the transmission gear 33 to prevent the transmission gear 33 from rotating in the opposite direction, and the above actions are repeated to realize automatic riveting of the stud 51 on the riveting position 52 of the product material strip 37, thereby reducing manufacturing costs and improving production efficiency.

[0046] In another embodiment of the present invention, the power gear 33 adopts a hook gear; specifically, the hook gear is used in conjunction with the transmission member 58 and the anti-backward assembly 63 to further improve the one-way rotation effect of the loading plate. The hook gear is an existing structure, and this embodiment uses it to cooperate with the transmission member 58 and the anti-backward assembly 63 to improve the one-way rotation effect. Its specific structure is not described in detail here.

[0047] In another embodiment of the present invention, the loading assembly 61 also includes a fixed shaft 41 and a fixed wheel 45; the loading plate 38, the power gear 33 and the fixed wheel 45 are all coaxially arranged on the fixed shaft 41, and fixed wheels 45 are arranged on both sides of the power gear 33; the diameter of the fixed wheel 45 is larger than the diameter of the power gear 33, and the fixed wheel 45 slides in contact with the frame opening 23; specifically, the two fixed wheels 45 at the upper and lower ends of the power gear 33 make the structure more stable, and the diameters of the two fixed wheels 45 are larger than the diameter of the power gear 33; the fixed wheel 45 slides in contact with the side wall of the frame opening 23, which can avoid the power gear 33 from colliding with the side wall of the frame opening 23 while improving the stability of rotation.

[0048] In another embodiment of the present invention, the transmission member 58 includes a movable seat 48 and a transmission hook 42;

[0049] The movable seat 48 is provided with a card slot 28, which cooperates with the force transmission pin 32.
