The design of the flipping assembly can quickly realize the end-face flipping of the circuit board, improving the flipping efficiency during the testing process, increasing the diversity of device functions, improving the conveying stability of the circuit board and increasing the functional diversity.

[0027] As Figures 1 to 4 shown, as a preferred solution, the driving assembly includes a transmission shaft 8 coaxially arranged on one of the support shafts 3.

The driving motor 9 drives the two groups of support shafts 3 to rotate through the transmission shaft 8, and then the first conveyor belt 7 starts to operate. The first conveyor belt 7 feeds the integrated circuit board into the system. When the circuit board reaches the specified position between the second conveyor belts 15, the servo motor 16 stops rotating, and the cylinder 21 is started.
