[0028] See also Figure 1 Combined with Figure 2 , describing the working principle of the present invention: the processed disc part 50 falls onto the upper surface of the input belt 60 through the aforementioned feed port 18. When the aforementioned input sensor 20 does not sense the presence of the disc part 50 at the corresponding position, the aforementioned input drive mechanism 14 works to move the disc part 50 on the input belt 60 forward until it is sensed by the input sensor 20.

The aforementioned height sensor 34 detects the disc part 50 located in the part slot 331 through the detection opening 332, and determines which side of the disc part 50 is facing upward by detecting the edge height of the disc part 50 (usually the positive side). The edge facing upward is low, while the edge facing upward is high). For example, if the structure to be detected is that the reverse side of the disc part 50 faces upward, the aforementioned flip cylinder 32 works, and the rotating shaft 321 drives the part holder 33 to rotate 180°, so that the front side of the detected disc part 50 faces upward; when the next disc part 50 enters the part slot 331 from the input mechanism 1, the disc part 50 in the aforementioned part slot 331 is ejected and falls onto the upper surface of the output belt 70 of the output mechanism 2 through the bracket 40. When the aforementioned output sensor 30 senses that there is a disc part 50 on the output belt 70, the aforementioned output drive mechanism 24 works, so that the corresponding disc part 50 moves backward to the position of the output rear retaining edge 27 and waits for the operation of the next automation step, thereby completing the conveying, flipping and loading actions of the entire device.
