The present invention relates to the technical field of liquid crystal panel manufacture, and discloses a cushion block for glass comprising a cushion block body. The cushion block body comprises a support part, at least a portion of which is configured for extending into the underneath of the glass to support a bottom surface of the glass, the portion of the support part configured for extending into the underneath of the glass forming a supporting surface for supporting the bottom surface of the glass; a fixation part fixedly connected with the support part, configured for fixedly connecting with a base platform; and a limitation protrusion fixed to the support part and higher than the supporting surface, wherein the limitation protrusion is located outside the portion of the support part configured for extending into the underneath of the glass, and a surface of the limitation protrusion connecting with the supporting surface forms a limitation surface higher than the supporting surface, configured for abutting against a side of the glass supported on the supporting surface. For the above cushion block for glass, while the supporting surface supports the bottom surface of the glass, the limitation surface can abut against the side surface of the glass to prevent the glass from sliding along the supporting surface, and moreover to prevent the glass from falling off from the cushion block for glass during overturn and movement, thereby improving the support stability of the cushion block for the glass.
