[0040] Working principle:

[0041] 1. First, fix the PCB board positioning module 1 and the lower visual assisted positioning module 3 on the equipment platform, mount the product placement module 2 on a driving component such as a four-axis or six-axis robot or a multi-axis motion module, and the upper visual assisted positioning module 23 first takes a photo of the PCB board placement slot on the PCB board positioning module 1 and saves the position information to provide a position reference for the subsequent placement of the PCB board 42;

[0042] 2. The top clamping cylinder 12 of the PCB board positioning module 1 rises and returns to the initial position, and the side push positioning cylinder 13 withdraws to the initial position. At this time, the PCB board positioning module 1 sends a signal to the PCB board vacuum pick-and-place module 21 through the cylinder magnetic sensor to place the PCB board;

[0043] 3. The vacuum pick-and-place module of the PCB board and FPC cable is driven to the top of the PCB board and FPC cable material box by the driving component. The upper visual auxiliary positioning module 23 takes pictures to locate the specific position of the PCB board and FPC cable in the material box, and gives the position information to the driving component of the vacuum pick-and-place module 22 of the PCB board and FPC cable. After receiving the real-time position information, the driving component of the vacuum pick-and-place module 22 of the PCB board and FPC cable automatically adjusts the vacuum suction head of the PCB board and FPC cable to match the position of the PCB board and FPC cable in the material box;

[0044] 4. The drive assembly drives the vacuum suction head of the PCB board vacuum pick-and-place module to move to the PCB board picking position of the material box. The vacuum suction head is driven by the cylinder to drop to the PCB board suction position, the vacuum is automatically turned on, the PCB board is sucked, and the cylinder rises to its position;

[0045] 5. The driving component drives the PCB board vacuum pick-and-place module to move above the lower visual assisted positioning module 3; the lower visual assisted positioning module 3 takes a picture of the PCB board outline to save the PCB board's external dimension information;

[0046] 6. The driving component drives the PCB board vacuum pick-and-place module 21 to move above the PCB board positioning module 1; the driving component compares the previously saved PCB board shape dimension information with the PCB board position reference information of the PCB board placement slot on the PCB board positioning module, adjusts the position deviation, and then places the PCB board into the PCB board placement slot on the PCB board positioning module 1;

[0047] 7. The PCB board positioning cylinder of the PCB board positioning module 1 moves forward to the right position and pushes the PCB board against the reference surface of the PCB board placement slot. The PCB board clamping cylinder descends, driving the pressure head on the cylinder to press the PCB board, ensuring that the PCB board is accurately positioned and firmly fixed;

[0048] 8. The driving component drives the vacuum suction head of the FPC cable vacuum pick-and-place module 22 to move to the FPC cable picking position of the material box. The vacuum suction head is driven by the cylinder to drop to the FPC cable suction position, the vacuum is automatically turned on, the FPC cable is sucked, and the cylinder rises to the position;

[0049] 9. The driving component drives the FPC cable vacuum pick-and-place module 22 to move to the top of the lower visual auxiliary positioning module 3; the lower visual auxiliary positioning module 3 takes a picture of the FPC cable contour to save the FPC cable's external dimension information;

[0050] 10. The driving component drives the FPC cable vacuum pick-and-place module 22 to move above the PCB board positioning module; the driving component compares the previously saved FPC cable shape dimension information with the reference position information of the plug-in connector on the PCB board on the PCB board positioning module, adjusts the position deviation in the XY and R axis directions, and then the laser distance sensor on the product pick-and-place module detects the Z-axis relative distance between the FPC cable and the plug-in connector on the PCB board. After the XYZ and R-axis positions of the FPC cable and the plug-in connector on the PCB board are adjusted, the FPC cable is accurately inserted into the connector corresponding to the PCB board on the PCB board positioning module;

[0051] 11. Then repeat steps 1-10 to complete the assembly of other FPC cables and corresponding connectors on the PCB board.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
