Step 4: After passing the inspection, the PCBA is moved to the second placement station, and the clamping and flipping device drives the PCBA to flip 180 degrees; Step 5: When the second proximity switch senses that the PCBA has arrived at the second mounting station, the supporting mechanism rises to support the PCBA, and the second driving mechanism drives the second picking mechanism, which has picked up the shielding tape from the second feeding mechanism, to move above the PCBA.
