10. A method for implementing a PCB assembly device according to any one of claims 1 to 9, characterized in that: The following steps are involved: (I) The operator starts the equipment, puts the whole PCB board into the placement hole of the carrier, and then presses the confirmation button box, the feed cylinder works, and drives the carrier to move horizontally into the bottom of the suction head plate; the suction head plate lifting cylinder drives the suction head plate to move downward, sucks the whole PCB board and then rises, at the same time, the stepper motor drives the screw rod to move, and drives the top column to rise through the lifting block, and the whole PCB board is ejected from the carrier, so that the whole PCB board can be smoothly separated from the carrier; after the suction head plate lifting cylinder rises to the set position, the feed and transport cylinder drives the suction head plate to move horizontally to the top of the carrier platform, and the suction head plate lifting cylinder drives the suction head plate to descend, and the whole PCB board is placed in the acupuncture point of the carrier platform, and the suction head plate lifting cylinder and the feed and transport cylinder are reset; (ii) The punching cylinder drives the lifting plate downward, thereby driving the punching head downward. The first guide rod is first inserted into the carrier platform to locate the position of the cutter seat. Then the cutter on the cutter seat contacts the entire PCB board. Under the action of the compression spring, the redundant connecting pieces between the entire PCB board are cut off to obtain a separate PCB board. The servo motor rotates, driving the carrier plate to rotate, rotating the cut PCB board out of the cutting station, and sending another empty carrier platform into the cutting station to wait for another action. (3) The vibrating plate of the magnetic plate aligns the material of the magnetic plate and transports it backward to the positioning block of the magnetic plate; (IV) The transporting transverse shifting module moves, driving the first transporting assembly to move above the uniform magnetic plate positioning and lifting mechanism. The transporting and lifting cylinder drives the suction head to extend into the uniform magnetic plate positioning block to suck the uniform magnetic plate and reset it upward. At the same time, the uniform magnetic plate lifting cylinder drives the ejector pin to move upward to eject the uniform magnetic plate. (V) The transport lateral shift module moves, driving the first transport assembly to move above the carrier plate with the PCB board, and the transport lifting cylinder drives the suction head down to place the magnetic shim on the PCB board in the carrier plate, completing the assembly of the PCB board and the magnetic shim; (Six) The transporting and lateral shifting module moves to drive the second transporting component to move above the assembled product. The transporting and lifting cylinder drives the suction head down to suck the assembled product and reset it upward. At the same time, the PCB board lifting cylinder drives the ejector rod upward to eject the assembled product upward. The stepping hollow motor drives the suction head to rotate and rotate the assembled product to the angle matching the fixture disk. The transporting and lateral shifting module moves to drive the second transporting component to move above the fixture disk and place the assembled product into the acupuncture point of the fixture disk.
