[0045] The first supporting arm 420 and the second supporting arm 430 support the plate 800, and the first supporting arm 420 and the second supporting arm 430 are located in a horizontal position, so that the plate 800 can be relatively horizontal. Specifically, positioning grooves can be provided on the side walls where the first supporting arm 420 and the second supporting arm 430 are close to each other, and the two side edges of the plate 800 can be placed in the two positioning grooves, thereby playing a limiting role.

[0046] In some embodiments of the present invention, Figure 5 As shown, the automatic eyelet riveting device further includes a control module 610, and the control module 610 is connected to the plane displacement module 300 and the punching drive assembly 210 respectively.

The prompting module 640 can be a sound or light alarm. The control module 610 controls the prompting module 640 to alarm according to the result of whether the optical receiver 632 receives light. When the upper stamping part 220 and the lower die pin 230 are directly opposite through the pad hole, the light emitted by the optical emitter 631 will also pass through the pad hole and be received by the optical receiver 632. The control module 610 prompts through the prompting module 640 that stamping can be performed at this time to implant the eyelet 700 into the pad hole, reducing the probability of damaging the plate member 800.
