The invention provides a vacuum platen which is formed by fixing and combining a platen body and a blank holder, wherein the platen body has a circular ring side wall and a bottom positioned in the circular ring side wall; a vacuum port and a circular ring inner wall are arranged on the bottom in a penetrating way; the circular ring inner wall comprises a through hole for a pump body for pumping materials to pass through; a vacuum cavity is surrounded by part of the side wall, the bottom and the inner wall of the platen body and the blank holder; and a central hole and a group of meshes are arranged on the blank holder, wherein the central hole corresponds to the through hole of the platen body, and the meshes penetrate through the blank holder. The invention has the main beneficial effects of pumping the surface of glue into a vacuum state in advance, reducing the waste caused by evacuating new materials, saving the replacing time of the new materials, improving the work efficiency of filling glue, greatly reducing the residual materials in a glue bucket, saving the materials and reducing the pollution of chemical materials to the environment.
