Abstract
The invention provides a substrate absorption device comprising a pedestal, an elastic sealing ring, an absorption disk and a taper-pipe-shaped elastic lining. The pedestal comprises a top plate on which a recess part is formed. The peripheral edge of the recess part is provided with a flange stretching towards the center of the recess part. The elastic sealing ring is arranged in the recess part. The absorption disk is arranged on the elastic sealing ring and comprises an absorption surface which projects out of the top plate, and one part of the absorption disk is positioned in the recess part and can compress the elastic sealing ring to move relative to the pedestal. The taper-pipe-shaped elastic lining is provided with a narrow opening rim and a broad opening rim, wherein the narrow opening rim is connected with a part of the absorption disk, which projects out of the flange, and the broad opening rim can be adhered to the top plate in a sliding manner and cover a gap between the absorption disk and the flange. When the absorption disk compresses the elastic sealing ring inwards to enter the recess part and simultaneously drives the narrow opening rim to compress the taper-pipe-shaped elastic lining to deform. Such design prevents dust, scraps or other impurities from entering the absorption device so as to ensure the absorption force of the substrate absorption device.
