Regarding the manufacturing method of the three-dimensional object, the invention patent of the Republic of China Publication No. I447080 discloses a method for manufacturing a curved glass, which mainly utilizes an upper mold core and a lower mold core, the upper mold core has a gas passage and a gas passage connected to each other. a curved chamber, the lower mold core is a porous material and has a lower curved chamber, and the gas passage and the lower mold core are connected with a pressure mechanism. When manufacturing, the peripheral portion of a glass plate is first sandwiched between the upper mold and the lower mold and the interior of the glass plate is located between the upper curved chamber and the lower curved chamber, and then the glass plate is Heating and using the pressure mechanism to create a pressure difference between the upper curved chamber and the lower curved chamber, thereby deforming the interior of the glass plate and fitting the lower curved chamber to form a curved glass. However, since the manufacturing method is such that the interior of the glass plate is deformable, the peripheral portion of the glass plate is first sandwiched between the upper mold core and the lower mold to fix the glass plate before the heating, and then the heating and The pressure difference deforms the interior of the glass plate to form the curved glass, and after the curved glass is formed, it is further processed to remove the peripheral portion of the curved glass (the portion for fixing the glass plate) to obtain a curved glass of a correct shape. In summary, since the manufacturing method requires the glass plate to be fixed with an additional structure and the curved glass needs to be additionally processed to remove the peripheral portion thereof after molding, the manufacturing process of the manufacturing method is cumbersome.

In addition, the invention patent of the Republic of China Publication No. I406826 discloses a method for manufacturing a three-dimensional glass, which mainly utilizes an upper mold core and a lower mold core, the upper mold core has a convex body, and the lower mold core There is a groove and a plurality of gas passages communicating with each other, and the gas passages are connected with a pressure mechanism. The manufacturing method is to first place a periphery of a glass plate on a positioning groove around the lower mold to position the glass plate, and then heat the glass plate and use the convex body of the upper mold to add the inside of the glass plate. The pressure is used to inhale the inside of the glass plate, and the inside of the glass plate is deformed and attached to the groove to form a stereoscopic glass. However, since the manufacturing method is such that the interior of the glass plate is deformable, the peripheral portion of the glass plate is positioned with the lower mold to position the glass plate before manufacturing, and then the heating, the convex pressing and the concave are utilized. The groove suction deforms the interior of the glass plate to form the stereoscopic glass, and after the stereoscopic glass is formed, the peripheral portion of the stereoscopic glass (the portion for positioning the glass plate) is removed to obtain a correct shape. glass. In summary, since the manufacturing method requires positioning the glass plate with an additional structure and the additional processing of the three-dimensional glass after molding to remove the peripheral portion thereof, the manufacturing process of the manufacturing method is cumbersome; in addition, since the gas passages are Processed and limited in number, these gas channels do not provide a uniform pressure distribution to effectively adsorb the internal deformation of the glass plate.

Furthermore, the invention patent of No. I301828 discloses a method for manufacturing curved glass, which mainly utilizes a fiber cloth, an upper mold core and a lower mold core, the upper mold core has a convex curved surface, and the lower mold core Has a concave curved surface. When manufacturing, a glass plate is first placed on the fiber cloth and the glass plate is located between the convex curved surface and the concave curved surface, and then the glass plate is heated and the convex surface of the upper mold core is used and The concave curved surface of the lower mold core pressurizes the glass plate, thereby deforming the glass plate to form a curved glass. However, since the manufacturing method is such that the glass plate can be positioned and the curved glass does not leave a processing mark, the fiber cloth needs to be additionally prepared, so that the processing apparatus of the manufacturing method is complicated.

Further, Japanese Laid-Open Patent Publication No. Hei 11-10472 discloses a method of transporting a wafer mainly by using a porous substrate and a pressure mechanism connected to each other to adsorb a wafer and thereby move the wafer.
