The rotating ring 340 positioned at the first support plate 320 has an extension arm 350, the extension arm 350 is protruded in a radial direction and positioned at a side of the first support plate 320 far from the second support plate 330, and the extension arm 350 has a sliding groove provided along an extending direction thereof.

The base 310 further has a guide rail 360 disposed perpendicular to the rotational axis of the rotating ring 340, the guide rail 360 slidably fits a slider 361 and the slider 361 is driven by a first driver 364, the slider 361 has a sliding column 363, and the sliding column 363 extends from the slider 361 to the sliding slot.

The positioning device is provided between the first support plate 320 and the second support plate 330, and has the stage 110 for fixing the product.

The bending device is arranged between the first support plate 320 and the second support plate 330 and fixedly connected between the two rotating rings 340, the bending device is provided with a pressure arm 210 extending towards the objective table 110, the end part of the pressure arm 210 is hinged with a cylindrical rolling block 220, the rotating axis of the rolling block 220 is coincided with the central axis thereof, and the rotating axis of the rolling block 220 is arranged in parallel with the rotating axis of the rotating rings 340.

When a bending operation is performed, after an object is fixed on the stage 110 of the positioning device, the first driver 364 pushes the slider 361 to slide along the guide rail 360, so that the slider 361 pushes the sliding column 363, and under the driving action of the sliding column 363, the sliding column 363 pushes the extension arm 350 and slides along the sliding slot, and the rotating ring 340 rotates. After the rotation ring 340 is rotated, the bending device also starts to rotate. By controlling the rotation direction of the rotation ring 340, the rolling block 220 approaches the object stage 110 and presses the object on the object stage 110, so that the object is bent and deformed. The first actuator 364 pushes the sliding block 361 to slide for different distances, so that the rotating ring 340 can rotate for different angles, and the rolling block 220 can displace to different degrees relative to the stage 110, thereby allowing the rolling block 220 to bend the object to different angles.

It should be noted that, because the rolling block 220 is hinged to the pressing arm 210, in the process of bending the object, along with the rotation of the rotating ring 340, the rolling block 220 will continuously bend the object in one direction, relative displacement will necessarily exist between the rolling block 220 and the object, and the rolling block 220 can buffer the relative displacement by rolling, so as to avoid scratching the object.
