The invention discloses an assembling type wooden box for packaging ultra-thin sheet glass. The wooden box comprises a grating bottom plate, pressing plates, side caps, an upper pressing strip and strapping tape. The pressing plates are pressed on a front glass face and a rear glass face of a glass stack respectively in a fit manner, and are in a shape like a Chinese word 'jing', and the four sides of each pressing plate are matched with a glass plane; the two sides of the glass stack are sleeved with the side caps; and each side cap comprises a top plate, side wall plates and a bearing bottom plate, and the top plates, the side wall plates and the bearing bottom plates are connected to form rectangular cavities for containing the side edges of the glass stack; the upper pressing strip is in a rectangular shape, and a third fiber plate matched with the top of the glass stack is arranged on the inner side of the upper pressing strip; and the strapping tape straps and fixes the grating bottom plates, the pressing plates and the side caps packaged with the ultra-thin sheet glass; according to the packaging technology of a mechanical arm, the wooden box is assembled according to the sequence, and the ultra-thin sheet glass can be tightly wrapped by the wooden box; the structure of the side caps can protect the side edges of the glass stack well, and the breakage rate of the ultra-thin sheet glass in the packaging transportation process can be greatly reduced.
