[0022] The aforementioned pin 111 is a T-shaped pin, and the slot 112 is a T-shaped slot.

[0023] The angle between the first support surface 51 and the second support surface 52 of the aforementioned fan-shaped bracket 5 is 62°.

[0024] Example 2: A workpiece flipping device includes: a base 1 and a front conveyor belt 2 and a rear conveyor belt 3 disposed on both sides of the base 1. A square frame 4 located on one side of the base 1 is disposed between the front conveyor belt 2 and the rear conveyor belt 3. A motor 6 is installed on the other side of the base 1. Each of the four corners of the square frame 4 has an extension plate 10. Four fan-shaped supports 5 are movably connected to the four end faces of the square frame 4 through at least one pair of pins 111 and slots 112. The two sides of the fan-shaped supports 5 along the circumference of the square frame 4 are respectively a first support surface 51 and a second support surface 52.

[0030] The working principle of this patent is as follows: First, the relative position between the fan-shaped support 5 and the square frame 4 is adjusted according to the size of the workpiece, and the interval between the front conveyor belt 2, the rear conveyor belt 3 and the flipping device is moved accordingly. At this time, the flipping device can just accommodate the workpiece. Then, the workpiece is placed on the front conveyor belt 2, and the workpiece is transferred to the first support surface 51 of the fan-shaped support 5 by the conveying of the front conveyor belt 2. The square frame 4 is rotated under the drive of the motor 6. When the square frame rotates 90°, the workpiece is located above the directional frame and the side of the workpiece is pressed against the transition surface 41. When the square frame rotates 180°, the top of the workpiece is pressed against the second support surface 52 of the fan-shaped support 5, and the second support surface 52 is at a certain angle to the horizontal plane, so that the workpiece slides to the rear conveyor belt 3 under the action of gravity, and is transported to the designated position by the conveying of the rear conveyor belt 3.

[0031] When the above-mentioned workpiece flipping device is used, it not only ensures that the workpiece can be transported smoothly, but also flips the workpiece through the square frame and the fan-shaped support. During the rotation, the first support surface, the transition surface and the second support surface come into contact with different surfaces of the workpiece in turn, which greatly reduces the impact on the workpiece during the flipping process. It is also more convenient to process or inspect the bottom and top of the workpiece. Furthermore, by changing the relative position of the fan-shaped support and the square frame, the flipping device can adapt to workpieces of different sizes, which is convenient for subsequent processing or inspection of workpieces of different sizes.
