[0028] The staggered flow line 4 includes a first conveyor line 401, a slide table 402 is fixedly connected to the conveyor belt of the first conveyor line 401, a second flow line 403 is fixedly connected to the slide table 402, the second flow line 403 is arranged parallel to the main flow line 2 and the return flow line 13, and the first conveyor line 401 is located between the main flow line 2 and the PCB feeding flow line 6.

The defective product unloading cylinder 902 and the defective product flow channel 901 are located on both sides of the main flow line 2. After the defective products are detected by the laser detector 802, the carrier carrying the defective products on the main flow line 2 is lifted by the lifting cylinder 12 at the NG unloading module 9, and then pushed into the defective product flow channel 901 by the defective product unloading cylinder 901. The defective product flow channel 901 and the defective product unloading cylinder 902 are both fixedly connected to the base 1.

The roller is slidably connected to the Z-shaped groove. A CCD camera is fixedly connected to the base plate 702. The CCD camera is used to detect and align the PIN pin hole positions on the PCB.

[0032] The working principle of this invention is as follows: In use, the PCB carrier is transported via the main flow line 2, the carrier transfer robot 5, the return flow line 13, and the staggered flow line 4. Blocking cylinders 11 and lifting cylinders 12 block the PCBs at various workstations and lift the carriers as needed for processing and inspection. The PCBs are fed from the PCB feeding flow line and lifted by the lifting cylinder 12. Then, the two-axis loading module 301 and the pneumatic gripper 303 grasp and transfer the PCBs to the P on the second flow line 403. Inside the CB carrier, the second flow line 403 transports the PCB carrier loaded with the PCB to the main flow line 2. The PCB undergoes pin insertion processing at the pin insertion module 7. At this time, the pin translation linear module 701 drives the base plate 702 to move, causing the guide head 706 to move to the pin insertion position on the PCB. The feeding mechanism 10 delivers the PIN pins into the feed tube 707. The PIN pins fall into the feed channel of the misalignment slider 705 within the feed tube 707. Then, the pin lifting linear module 703 drives the insertion block 704 to slide downwards. During the sliding process of the implant block 704, the misaligned slider 705 slides towards the guide head 706 under the action of the Z-shaped groove until the material channel of the misaligned slider 705 aligns with the material channel of the guide head 706. At this time, the PIN needles flow from the misaligned slider 705 into the guide head 706, and the implant block 704 continues to descend to press the PIN needles into the PCB. After the PCB has completed the pin insertion at all pin modules 7, at the laser detection module 8, the laser measuring instrument 802 is moved by the two-axis moving module 801 to detect the movement of the laser measuring instrument. The PIN pins on the PCB are inspected to check if they are properly inserted. Any PIN pins that are not properly inserted are considered defective and flow to the NG unloading module 9 on the main line 2. The NG unloading module 9 is lifted by the lifting cylinder 12 and pushed into the defective unloading channel 901 by the defective unloading cylinder 902. The qualified PCB is then transferred to the return line 13 by the carrier transfer robot 5. After the PCB is unloaded on the return line, the PCB carrier continues to transfer to the main line 2 via the staggered flow line 4.
