The automatic flipping and positioning device for double-sided marking of PCB boards according to any one of claims 3 to 4, characterized in that, The first mounting plate includes multiple module plates, including a first module plate connected to the flip support structure and a second module plate detachably connected to the first module plate. Multiple first vacuum suction cups are mounted on both the first module plate and the second module plate.

7. The automatic flipping and positioning device for double-sided marking of PCB boards according to claim 6, characterized in that, The automatic flipping and positioning device for double-sided marking of PCB boards includes a horizontal displacement mechanism mounted on the device base and a telescopic fork arm slidably mounted on the horizontal displacement mechanism along the driving direction of the horizontal displacement mechanism. The direction in which the horizontal displacement mechanism drives the telescopic fork arm to slide is perpendicular to the output shaft of the motor and extends horizontally. The telescopic movement direction of the telescopic fork arm is parallel to the output shaft of the motor. A first insertion hole is provided at the end of the first module board away from the flipping support structure. A plug and the first insertion hole are respectively provided at both ends of the second module board in the first direction. The plug of the second module board adjacent to the first module board can be inserted and engaged to fix it to the device. In the first socket of the first module board, the plug of one of the two adjacent second module boards can be inserted and locked into the first socket of the other second module board. The second module board has a second socket on the end facing the retractable fork arm in the second direction. The first direction is perpendicular to the second direction, and the second direction is parallel to the output shaft. When the first module board and the second module board are in the first working position, the retractable fork arm can be inserted into the second socket of the second module board and driven by the horizontal displacement mechanism to move away from the first module board, thereby separating the second module board from the adjacent first module board or from the adjacent second module board.

8. The automatic flipping and positioning device for double-sided marking of PCB boards according to claim 7, characterized in that, The inner wall of the first socket is provided with elastic clips on both sides, and the plug is provided with slots on both sides. When the plug is inserted into the first socket, the elastic clips are engaged in the corresponding slots so that the plug is locked in the corresponding first socket. When the second module board is subjected to an external force and moves away from the adjacent first module board or away from the adjacent second module board, the plug of the second module subjected to the external force squeezes the cooperating elastic clips and causes the cooperating elastic clips to disengage from the corresponding slots, so that the second module subjected to the external force can be separated from the adjacent first module board or second module board.

9. The automatic flipping and positioning device for double-sided marking of PCB boards according to claim 8, characterized in that, The second module plate is internally equipped with a trigger mechanism and movable extrusion heads corresponding to each slot. The extrusion heads can extend into or leave the corresponding slots. When the retractable fork arm is not inserted into the second insertion hole of the second module plate, the extrusion head does not enter the corresponding slot. When the retractable fork arm is inserted into the second insertion hole of the second module plate, it can cause the trigger mechanism to move, so that the trigger mechanism drives the extrusion head into the corresponding slot, thereby pushing the elastic card head in the slot out of the slot.

10. The automatic flipping and positioning device for double-sided marking of PCB boards according to claim 9, characterized in that, The second module board has a trigger operation cavity inside, which is connected to the second insertion hole and slot of the corresponding second module board. The trigger operation cavity contains a trigger tongue, a first elastic element, a lever, and a scissor lever mechanism. The scissor lever mechanism includes a first scissor lever, a second scissor lever, a third scissor lever, and a fourth scissor lever. An elastic reset element connects the first and second scissor levers. One end of the trigger tongue is connected to the cavity wall of the trigger operation cavity through the first elastic element. The middle portions of the first and second scissor levers are hinged to the cavity wall of the trigger operation cavity via hinge shafts. The first ends of the third and fourth scissor levers are hinged to each other, and the second end of the third scissor lever is hinged to the first scissor lever. The second end of the fourth scissor bar is hinged to the second scissor bar. The pressing head is connected to the opposite ends of the first and second scissor bars. The lever is connected to the trigger tongue. When the retractable fork arm is not inserted into the second socket of the second module plate, the trigger tongue is in a non-triggered position, and the elastic reset member keeps the first and second scissor bars in a first position. In the first position, the pressing head does not enter the corresponding slot. When the retractable fork arm is inserted into the second socket of the second module plate, it can push the trigger tongue to the triggered position, so that the lever drives the first and second scissor bars to open, so that the pressing head enters the corresponding slot and pushes the elastic locking head out of the slot.
