[0001] The utility model relates to the technical field of PCB manufacturing, in particular to a coding blackening component and a circuit board full-automatic dot-digging and blackening machine. Background Art

[0002] Optical positioning points, commonly known as "Mark points", are the points used by the machine to locate the PCB board when it is taken to the machine for soldering. Generally, PCB boards with surface mount components need to set Mark points. In mass production, the placement machine can be calibrated by the operator manually or automatically by the machine to find the Mark points, providing a common positioning point for all steps in the assembly process to locate the circuit pattern. Therefore, Mark points are crucial to SMT production.

[0003] Bad optical positioning points on the PCB need to be burned off. Conventional methods of removal are manual, which is time-consuming. In addition, the PCB usually needs to be turned over during the production process, which is not only inconvenient to operate but also easy to damage the PCB.

[0011] Furthermore, the flip feeding assembly also includes a mounting frame, a flip motor and a flip plate.
