Equipment for stacking PCB (Printed Circuit Board) substrates and keeping preset stacking style

The invention discloses a device for stacking PCB substrates and keeping a preset stacking style, the device comprises a holder and a clamping device, the holder comprises clamping pieces at two ends and clamping pieces at two sides, the clamping device is matched with the holder and clamps the holder, when the device is used, the PCB substrates are stacked by using the holder and the clamping device according to the preset style, and the preset stacking style of the PCB substrates is kept. And the stacked PCB substrates and the release paperboards spaced from the PCB substrates are clamped by the clamping pieces at the two ends of the retainer and the clamping pieces on the two sides of the retainer, are separated from the equipment and are transported and stored along with the stacked PCB substrates. The method has the advantages that the PCB substrates can be stacked according to a preset pattern, and the preset pattern is kept until a next circuit loading process is entered; the next step of vacuum packag
