[0027] In this embodiment, by setting up a material distribution plate 210 and clamps 220 distributed around the circumference of the material distribution plate 210, a loading structure that can be used for continuous operation and adapt to workpieces of different specifications is constructed. Furthermore, by using the riveting mechanism 300 and the clamping plate 420, the workpiece can be automatically unloaded after riveting, thereby further improving work efficiency.

[0028] In one embodiment, please refer to Figure 1 The clamp 220 and the dispensing plate 210 are detachably connected.

[0029] In one embodiment, please refer to Figure 1 The material distribution plate 210 has bases 240 distributed circumferentially, and the clamps 220 are threadedly connected to the bases 240.

[0030] In this embodiment, the clamp 220 and the base 240 are connected by threads, which facilitates the replacement of the clamp.

Next, the servo motor 230 is started, driving the distribution plate 210 to rotate horizontally. Then, the riveting mechanism 300 rivets the workpieces. Finally, when the workpiece rotates with the distribution plate 210 to the discharge port 110, the unloading mechanism 400 clamps the workpiece and moves it to the slide rail 111 for unloading. This structure can effectively clamp workpieces of different specifications and achieve continuous riveting without stopping or reversing / forward movements, effectively improving overall work efficiency.
