At the same time, the second camera 93, driven by the sixth electric lead screw 91, moves along the Y-axis so that the shooting range of the second camera 93 can cover all the clamps on each carrier 5.

[0039] Optionally in this embodiment, the defective product flow line 10 includes a second frame 101, two rotating shafts, a second transmission belt 102, and a second motor 103. The two rotating shafts are rotatably connected to the second frame 101, the second transmission belt 102 is sleeved on the two rotating shafts, the rotating shaft of the second motor 103 is connected to either rotating shaft, and defective circuit boards can be placed on the second transmission belt 102.

[0040] Movement Process: The carrier 5, containing the housing, moves from the feed end of the main line 1 to the lifting mechanism 6 under the drive of the main line 1. The lifting cylinder 63 drives the lifting plate 62 to move upward along the Z-axis, and lifts the carrier 5 off the main line 1 via the top block. Then, the seventh electric screw 92 drives the second camera 93 to approach the carrier 5 along the Z-axis, and the sixth electric screw 91 drives the second camera 93 to move along the Y-axis. The second camera 93 captures and detects the position of the housing so that the assembly mechanism 7 can determine the position of the housing during the assembly process. The second suction nozzle 35 moves to the feeding mechanism 2 under the coordinated drive of the second electric screw 32, the third electric screw 33 and the fourth electric screw 34 and picks up the circuit board. Then, the circuit board is moved onto the intermediate transfer platform 42, and then the fifth electric screw 41 drives the circuit board... Approaching the assembly mechanism 7, the first suction nozzle 72 moves to the intermediate transfer table 42 under the drive of the six-axis robotic arm 71. After the first suction nozzle 72 picks up the circuit board, it moves to the top of the upper vision mechanism 8. The first camera 82 inspects the appearance of the circuit board. If the circuit board is unqualified, the six-axis robotic arm 71 moves the unqualified circuit board to the unqualified product flow line 10. Then the unqualified product flow line 10 removes the unqualified circuit board from the automatic circuit board assembly mechanism. If the circuit board is qualified, the assembly mechanism 7 assembles the qualified circuit board into the housing lifted by the lifting mechanism 6. Then the lifting mechanism 6 puts the carrier 5 and the housing with the assembled circuit board back onto the main flow line 1. Then the carrier 5 moves to the discharge end of the main flow line 1 under the drive of the main flow line 1. This process is repeated to realize the automated assembly of the circuit board.

[0041] The automatic circuit board assembly mechanism in this embodiment has the advantage of a high degree of automation.
