However, in the production process of part of the circuit boards, the demand for detecting both surfaces exists, so that the existing single-surface detection method is difficult to meet the detection demand. In order to solve the above problem, the embodiment is invented.

[0023] In addition, please refer to Figure 4 Figure 6 ​, a cambered ring 27 is installed on the support 22, and two top wheels 26 are installed on the movable plate 24. Two cambered notches are provided on the cambered ring 27 in a centrally symmetrical manner. The two top wheels 26 are located in the two cambered notches of the cambered ring 27. When the movable plate 24 rotates, the two top wheels 26 are driven to roll along the cambered ring 27.

At this time, the reverse thrust of the cambered ring 27 on the top wheel 26 disappears, and the movable plate 24 moves along the rotating shaft 23 in the direction close to the support 22 under the action of the elastic force applied by the slip ring 29, thereby driving the two clamping plates 25 to separate from each other, releasing the clamping of the circuit board, thereby achieving the technical effect that when the circuit board moves on the conveyor line, the two clamping plates 25 flip the circuit board 180 degrees by clamping and then release the clamping, so that the circuit board continues to follow the movement of the conveyor line.
