The invention provides an edge sealing method of a dipped veneer laminated board; the method can quickly and efficiently finish oriented assembly of edge sealing strips and edge sealing grooves; and the obtained dipped veneer laminated board is excellent in structure and size stability. The method comprises the following steps: two edge sealing groove thrust positioning guide rail pairs are placedon the wide edges and the long edges of the dipped veneer laminated board on a table surface for thrust positioning; two edge sealing strips are positioned on the other pair of wide edges and long edges of the dipped veneer laminated board, and are longitudinally and transversely pushed to glue with the edge sealing grooves on the wide edges and the long edges of the dipped veneer laminated board; the edge sealing groove thrust positioning guide rails are taken down; the dipped veneer laminated board is rotated by 180 degrees; two plane thrust positioning guide rails are contacted with the side surfaces of two edge sealing strips glued on the dipped veneer laminated board; and the two edge sealing strips are positioned on the other pair of wide edges and long edges, not glued with the edge sealing strips, of the dipped veneer laminated board, and are longitudinally and transversely pushed to glue with the edge sealing grooves on the dipped veneer laminated board.
