In application, the workpiece to be riveted is placed on the lower mold, then the second linear motion device moves the lower mold below the upper mold, then the first linear motion device drives the upper mold to press down, riveting the workpiece to be riveted. After riveting, the first linear motion device drives the upper mold to lift, then the second linear motion device drives the slide plate to pull the lower mold out from below the upper mold. The riveted workpiece is then removed, and the next workpiece to be riveted can be placed, and the riveting process can then begin. Since there is no need for operators to place the workpiece to be riveted on the lower mold or remove it from the lower mold, it can effectively avoid injury to operators and effectively improve the level of automation.

The first gripper and the second gripper are used to grip the workpiece to be riveted and the workpiece that has already been riveted. The third linear moving device and the lower linear moving device are cylinders or electric cylinders.

[0012] In the application of the automatic loading and unloading device, the first gripper picks up a workpiece to be riveted. Then, the third linear motion device drives the hanger to move until the second gripper is above the lower die. Next, the fourth linear motion device drives the hanger to move downwards until the second gripper can pick up a riveted workpiece on the lower die. The second gripper then picks up the riveted workpiece. The fourth linear motion device then drives the hanger to move upwards. The third linear motion device then drives the hanger to move until the first gripper is above the lower die. The fourth linear motion device then drives the hanger to move downwards, placing the riveted workpiece on the lower die. The fourth linear motion device then moves upwards, and the loading and unloading device drives the hanger away from above the lower die.

The third linear moving device 30 and the lower linear moving device are cylinders or electric cylinders.

[0028] When the automatic loading and unloading device is in use, the first gripper 33 grips a workpiece 35 that needs to be riveted. Then, the third linear motion device 30 drives the hanger 32 to move to a position where the second gripper 34 moves above the lower mold 19. Next, the fourth linear motion device 31 drives the hanger 32 to move downwards until the second gripper 34 can grip the already riveted workpiece 35 on the lower mold 19. Then, the second gripper 34 grips the already riveted workpiece. Next, the fourth linear motion device 31 drives the hanger 32 to move upwards. The third linear motion device 30 drives the hanger 32 to move the first gripper 33 above the lower mold 19.

The photoelectric sensor 37 is used to sense whether there is a workpiece to be riveted at the bottom of the flared groove 38. When the photoelectric sensor 37 senses that the workpiece 35 is in place, the loading and unloading conveyor belt pauses; after the first gripper 33 grips the workpiece 35, if the photoelectric sensor 37 does not sense the workpiece 35, the loading and unloading conveyor belt starts conveying until the photoelectric sensor 37 senses the next workpiece 35.

[0030] In this embodiment, the tail end of the guide plate 36 is provided with a lower groove 39, which is located above the loading and unloading conveyor belt. The lower groove 39 is used to place the riveted workpiece 35 gripped by the second gripper 34 onto the conveyor belt, avoiding obstruction by the guide plate 36.
