The utility model provides a vacuum adsorption disc. The tray comprises a tray body, a vacuum cavity capable of being communicated with a vacuum source or a vacuum generation device is formed in the disc body. The surface, facing an adsorbed object, of the disc body is generally a flat surface. The vacuum chuck is characterized in that an elastic sealing gasket is arranged on the surface of the chuck body around the opening of the vacuum cavity, and the thickness of the elastic sealing gasket is selected to enable the elastic sealing gasket to exceed the surface of the chuck body in a free state and to be approximately flush with the surface when an adsorbed object is adsorbed on the chuck body. According to the vacuum adsorption disc, the stable vacuum degree can be ensured, so that an object adsorbed by the vacuum adsorption disc can be stably and reliably adsorbed on the vacuum adsorption disc. 本实用新型提供一种真空吸附盘，包括盘体，所述盘体中形成有能够与真空源或真空发生装置连通的真空腔，所述盘体朝向被吸附物体的表面大体是平坦表面，其特征在于，在所述盘体的所述表面上环绕着所述真空腔的开口设置有弹性密封垫，所述弹性密封
