[0036] The conveying mechanism 20 includes a conveying driving motor and a conveyor belt, and the conveyor belt is installed at the output end of the conveying driving motor; the conveying driving motor drives the conveyor belt to run, which can stably and continuously convey the circuit board, ensure the smooth movement of the circuit board between each detection mechanism, improve the detection efficiency, and avoid the position deviation or damage of the circuit board that may be caused by manual conveying.

[0037] The alignment mechanism 30 includes an alignment driving cylinder 31 and an alignment plate 32. The alignment plate 32 is installed at the output end of the alignment driving cylinder 31, and the alignment plate 32 is movably abutted against the circuit board on the conveying mechanism 20. The alignment driving cylinder 31 drives the alignment plate 32 to move and abut against the circuit board on the conveying mechanism 20, which can accurately adjust the position of the circuit board, so that the circuit board can be accurately aligned with other mechanisms during subsequent detection, ensuring the accuracy and consistency of detection and reducing false detection caused by position deviation.

The longitudinal movement driving cylinder 42 is installed on the support 41, the longitudinal movement slide 43 is installed at the output end of the longitudinal movement driving cylinder 42, and the detection probe 44 is installed on the longitudinal movement slide 43.

In this way, the conductivity of each circuit node on the circuit board can be comprehensively and accurately detected.

[0043] The driving cylinders in the lifting drive assembly 62 and the lateral drive assembly 63 drive the sliding seat to move, realize the lifting and lateral movement of the clamping member 64, and can accurately grasp and transfer the circuit board. Several clamping members 64 are evenly spaced and can grasp multiple circuit boards at the same time or grasp the same circuit board at different positions, thereby improving the efficiency and accuracy of material transfer.

[0044] The setting of the limit rod 65 can limit the sliding seat of the transverse drive assembly 63, ensuring the stability and position accuracy of the clamping member 64 during the movement, and avoiding deviation or shaking.

[0045] The appearance inspection mechanism 70 includes a transverse driving cylinder 71, a transverse slide 72 and a CCD camera 73. The transverse slide 72 is installed at the output end of the transverse driving cylinder 71. The CCD camera 73 is installed on the transverse slide 72 and faces the circuit board.

[0046] The appearance inspection mechanism 70 also includes a material placement seat for placing circuit boards, the synchronous material moving mechanism 60 is located above the material placement seat, and the CCD camera 73 faces the circuit boards on the material placement seat.

[0047] The lateral driving cylinder 71 drives the lateral slide 72 and the CCD camera to move, and can flexibly adjust the position of the camera so that it can perform a comprehensive appearance inspection on the circuit boards at different positions on the conveying mechanism 20. The CCD camera can clearly capture the image of the circuit board, and through image analysis, it can quickly and accurately find the appearance problems such as defects, stains, poor welding, etc. on the surface of the circuit board, providing an important basis for the quality control of the circuit board.

[0048] The material discharging seat provides a placement position for the circuit board to be inspected, and the synchronous material moving mechanism 60 is located above the material discharging seat, which is convenient for quickly grabbing and transferring the circuit board for appearance inspection, thereby improving the convenience and efficiency of inspection.
