Description

Technical Field

[0002] During the production of electronic products, several components are assembled and soldered onto PCBs to achieve conductivity and coordination of multiple functions. After soldering, the PCBs need to be transferred to a test machine for power-on testing. During the PCB transfer process, the PCBs to be tested are placed on trays, and then the stacked trays are transferred to the test machine to prevent damage caused by the stacked PCBs rubbing against each other. After arriving at the test machine, the PCBs on the trays are placed on the test machine for power-on testing. Currently, manual placement of test boxes is the main method, and manual handling is used between each process. After testing, the materials are collected manually. This method has high labor costs and cumbersome operations. Manual operation cannot achieve precise docking and has a high error rate. In addition, manual contact and grasping of the PCB board to be tested can easily lead to scratches on the PCB board due to misoperation. Contact between the PCB board and human hands can easily cause surface contamination of the PCB board, affecting the product yield rate.

If a linear series automated PCB board test line with a simple structure, precise positioning, automatic loading, grasping, inspection, material separation and loading can be designed, and an NG transfer mechanism can be set up, the above problems can be solved.

After the first detection position completes the test, the PCB board 7 is placed on the conveyor line 22 to be tested and flows into the next detection position. The manipulator assembly 5 at the next detection position clamps the PCB board 7 and places it into the testing machine 3 for testing. After all detection positions are completed, the products that have passed the test are placed into the tested conveyor line The feeding line 23 flows into the blanking machine 4, and the manipulator assembly 5 at the detection position of the blanking end of the blanking conveyor line 2 places the PCB board 7 on the tray of the blanking machine empty tray lifting module 44, and the loader empty tray lifting module 14 and the blanking machine empty tray handling module 45 respectively transfer the trays on the top of the loader full tray lifting module 13 and the blanking machine empty tray lifting module 44 to the other side, and synchronously lift the stacked trays by the height of one tray, and repeat the above steps. For the PCB boards 7 that fail the inspection, the manipulator assembly 5 at the corresponding inspection position clamps them to the corresponding NG conveyor line 6 and transfers them out.
