The application provides a formation negative pressure pipeline detection method, an electronic device and a computer readable storage medium, wherein the method can include: in the process of cell formation, controlling the negative pressure value of the formation equipment negative pressure pipeline to be in a set interval; obtaining the negative pressure change trend of the negative pressure pipeline of the formation equipment; based on the negative pressure change trend, judging the blockage condition of the negative pressure pipeline. In the implementation mode, not only can more accurate and objective blockage determination be achieved, but also the efficiency of blockage detection can be improved.

The application relates to the technical field of detection equipment, in particular to a symmetry part edge detection equipment and method based on air pressure detection, which comprises a platform substrate, an air cylinder arranged above the platform substrate, a detected hole penetratingly arranged on a part and a detection air nozzle, the detection air nozzle is controlled to ascend and descend through the air cylinder; the part is positioned and placed on the platform substrate, the detection air nozzle corresponds to the detected hole up and down when the part is installed in a normal direction; the symmetry part edge detection equipment based on air pressure detection can detect the edge reverse problem of the symmetry part which is prone to occur in the assembly process, avoids the misjudgment risk of manual visual inspection, can realize batch synchronous detection, and improves the detection efficiency.
