However, the existing optical inspection equipment requires the staff to remove the defective circuit board after inspection, which will cause additional time delay and reduce the inspection efficiency.

[0008] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

The first clamping plate and the second clamping plate limit the circuit board at the same time and drive the circuit board to rotate. When the circuit board rotates 180 degrees and contacts the conveying rail again, the conveying rail can inspect the turned-over circuit board. By flipping the circuit board, the other side can also be inspected, ensuring comprehensiveness and accuracy.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

An electric push rod 22 is fixed inside the fixed block 211. The output end of the electric push rod 22 is movably connected to a connecting rod 23. A fixed plate 24 is fixed to one side of the outer surface of the fixed block 211. One end of the fixed plate 24 is connected to the outer surface of the connecting rod 23 by a fixed shaft 25.

[0047] The square groove 21 is a square groove used to receive and position the circuit board to ensure its stable position during the blanking process. The fixing plate 24 is fastened to one side of the outer surface of the fixing block 211 as a supporting and fixing structure. One end of the fixing plate 24 is connected to the connecting rod 23 through the fixing shaft 25;

[0055] Push the defective circuit board down and it will fall into the centralized collection area for defective products through the unloading rail 28, waiting for the subsequent process.

[0056] This step reduces manual intervention and improves operational efficiency and consistency.

[0062] Working principle:

[0063] After the previous inspection process, the circuit board needs to be turned over for inspection.

[0064] At this time, when the circuit board is transferred to the bottom of the first clamping plate 35, the staff starts the motor 31 through the external control module, and the motor 31 drives the rotating shaft 33 to rotate.

[0065] And drive the fixing ring 34 to rotate, the first clamping plate 35 and the second clamping plate 36 simultaneously limit the circuit board, drive the circuit board to rotate,

[0066] When the circuit board is rotated 180 degrees and contacts the conveyor rail 12 again, the conveyor rail 12 can detect the turned-over circuit board.
