When the area of the adsorbed PCB board is small, it is only necessary to let the middle suction cup group contact and adsorb the PCB board.

[0064] The beneficial effect of adopting the above technical solution is that the auxiliary suction cup and the middle suction cup group can move synchronously at the same time because they are relatively centrally located.

[0073] like Figure 1 As shown, the robot 20 uses a suction device to grab the PCB board and place it on the exposure platform 19. After the exposure is completed, the flip rod 17 moves downward to the exposure platform 19 under the drive of the vertical linear module 16. At this time, the suction device fixed on the flip rod 17 is used to grab the PCB board.
[0074] When the PCB board is picked up, the turning rod 17 moves upward and turns a certain angle under the drive of the vertical linear module 16, so as to facilitate the grabbing of the manipulator 20. Then the manipulator 20 grabs the PCB board and places the PCB board on the next streamline platform 18.
[0075] At this time, the surface grabbed by the suction device of the flip rod 17 is the front side of the PCB board. When the manipulator 20 grabs the PCB board and places it on the streamline platform 18, the surface on the streamline platform 18 is the back side of the PCB board.
