Please refer to FIG. 2 , FIG. 7 and FIG. 8 , the present application provides a first embodiment of a glass sheet press molding method, using the glass sheet press molding equipment 100 provided in the first embodiment of the present application, including the following steps:

Step S1: placing multiple glass plate substrates on the first mold 70, heating and softening the multiple glass plate substrates, and preforming the multiple glass plate substrates to form preformed multiple glass plate substrates Glass plate substrate O;

Specifically, in this step, the plurality of glass plate substrates are placed on the first mold 70 of the transmission device 60, specifically placed on the first forming mold 72 of the first mold 70, and the peripheral edges of the plurality of glass plate substrates Located outside the first forming surface 721 of the first forming mold 72 , the distance between the periphery of the plurality of glass plate substrates and the periphery of the first forming surface 721 is 3-5 mm. The conveying device 60 transports the multiple glass plate base materials to the heating device 50, heats the multiple glass plate base materials to the forming temperature to soften the multiple glass plate base materials, and the multiple glass plate base materials are deformed by gravity, The first molding die 72 is bent in the thickness direction so as to preform a plurality of glass plate substrates to form a preformed plurality of glass plate substrates O. Among them, affected by the shape of the glass substrate or the gravity distribution, the preformed multi-piece glass substrate O is prone to deformation, resulting in a "pan" or "S" shaped surface, as shown in Figure 1.

Step S2: moving the first mold 70 carrying the preformed multi-piece glass plate substrate O to the bottom of the second mold 10, and passing through the suction port of the vacuum channel B, the preformed The gap between the multiple glass plate substrates O is vacuum adsorbed, so that the preformed multiple glass plate substrates O are vacuum bonded;

Specifically, step S2 includes:

Step S21: make the forming surface 1141 opposite to the surface of the preformed multi-piece glass plate substrate O, and along the direction of the height 100 of the glass plate press molding equipment, the forming surface 1141 and the preformed The distance between the surfaces of the multiple glass plate substrates O is 5 to 30 mm, and the suction port of the vacuum channel B is opposite to the periphery of the preformed multiple glass plate substrates O;

Specifically, in this step, the conveying device 60 transports the preformed multiple glass plate substrate O to the pressing device 40, so that the forming surface 1141 of the second mold 10 faces the surface of the preformed multiple glass plate substrate O, The suction port of the vacuum channel B of the second mold 10 is opposite to the periphery of the preformed multi-piece glass plate substrate O. Along the height direction (Z-axis direction) of the glass plate press molding equipment 100, the drive system drives the second mold 10 to move towards the first mold 70, and moves the molding surface 1141 of the second mold 10 to a distance from the preformed multi-piece glass plate base. 5-30mm on the surface of material O. When the suction port of the vacuum channel B of the second mold 10 is opposite to the periphery of the preformed multiple glass plate substrate O, the second peripheral side plate 124 is outside the periphery of the preformed multiple glass plate substrate O. The distance between two peripheral side plates 124 and the periphery of the preformed multi-slice glass plate substrate O is 20mm; The distance between 115 and the periphery of the preformed multi-piece glass plate substrate O is 5 mm. In this way, the adsorption effect of the second mold 10 on the preformed multi-piece glass substrate O can be ensured.

Step S22: Vacuum-adsorb the preformed multiple glass plate substrates O through the suction port of the vacuum channel B, so that the preformed multiple glass plate substrates O are vacuum bonded.

Specifically, in this step, the second vacuum system is turned on, and the periphery of the preformed multi-piece glass plate substrate O is vacuum-adsorbed through the suction port of the vacuum channel B. The air escapes from the periphery and enters the vacuum channel B, so that the preformed multiple glass plate substrates O are in a vacuum state, so that the preformed multiple glass plate substrates O are vacuum bonded. The second vacuum system remains open, which can prevent outside air from entering between the preformed multi-sheet glass substrates O again, and keep a vacuum state between the preformed multi-sheet glass substrates O, so that the preformed A plurality of glass plate substrates O maintains a state of being firmly bonded.

Step S3: Through the adsorption holes, the surfaces of the preformed multiple glass plate substrates O are vacuum bonded to the forming surface 1141, and the preformed multiple glass plate substrates O are fixed on the The molding surface 1141;

Specifically, in this step, the first vacuum system is turned on to evacuate the vacuum chamber A. Since the forming surface 1141 is provided with adsorption holes and the adsorption holes communicate with the vacuum chamber A, the forming surface 1141 and the preformed multi-piece glass plate substrate O The air pressure between them decreases, and under the action of atmospheric pressure, the preformed multi-sheet glass plate substrate O breaks away from the first mold 70, and moves toward the second forming mold 11 and is closely connected to the forming surface 1141 of the second forming mold 11. fit. The first vacuum system is kept in an open state, which can maintain the adsorption state of the second forming mold 11 to the preformed multi-piece glass substrate O.

Step S4: Driving the second mold 10 to drive the preformed multi-piece glass plate substrate O to move to the first mold 70, and the first mold 70 and the second mold 10 are pressed together on the preformed A plurality of glass plate substrates O formed to form a plurality of glass plate substrates after forming;

Specifically, in this step, the driving system drives the second mold 10 to continue to move toward the first mold 70 along the height direction (Z-axis direction) of the glass plate press molding equipment 100, so that the preformed multi-piece glass plate substrate O faces away from the first mold 70. The surface of the second molding die 11 is attached to the first molding surface 721 of the first mold 70, and the second molding die 11 applies a pressure directed to the first mold 70 to the preformed multi-sheet glass plate substrate O, so that the second molding The mold 11 and the first forming mold 72 jointly press-form the preformed multi-piece glass substrate O.

S5: Demoulding the formed plurality of glass plate substrates from the second mold 10;

Specifically, in this step, the first vacuum system is closed to allow air to enter between the molding surface 1141 of the second molding die 11 and the multi-sheet glass substrates after molding, and the second molding die 11 is used for the multi-sheet glass after molding. The adsorption effect of the plate substrate is eliminated, and the first mold 70 carries the formed multiple pieces of glass plate substrates. Turn off the second vacuum system to allow air to enter between the formed multiple glass plate substrates, so that the formed multiple glass plate substrates are no longer tightly bonded. The drive system drives the second mold 10 to move away from the first mold 70 , which can eliminate the limiting effect of the second mold 10 on the first mold 70 and facilitate the movement of the first mold 70 .

The periphery of the sheet glass substrate O is free to stretch. Turn on the first vacuum system to evacuate the vacuum chamber A. Under the action of atmospheric pressure, the preformed multi-piece glass substrate O moves toward the second forming mold 11 and then closely adheres to the forming surface 1141 . During this process, the atmospheric pressure exerts a pressure directed to the second forming mold 11 on the preformed multiple glass plate substrates O, which can simultaneously cause the deformed part in the middle of the preformed multiple glass plate substrates O to spread to the periphery, as shown in the figure 9. Therefore, it is beneficial to the shaping of the middle part of the preformed multi-piece glass substrate O, and the deformation of the middle part of the preformed multi-piece glass substrate O is improved. When there are wrinkles in the middle part of the preformed multiple glass plate substrates O, the atmospheric pressure exerts a pressure directed to the second molding die 11 on the preformed multiple glass plate substrates O, so that the preformed multiple glass plate substrates can be made simultaneously The folds in the middle part of O spread to the peripheral part.

In addition, the first molding die 72 is a frame body, and after the peripheral portion of the preformed multi-sheet glass plate substrate O is bonded to the first molding die 72 of the first mold 70, the second molding die 11 is used to preform the multi-piece glass plate substrate O. Sheet glass substrate O exerts the pressure pointing to the first mold 70, and there is an interaction force between the peripheral part of the preformed multi-sheet glass substrate O and the first molding die 72, so that the preformed multi-sheet glass substrate The deformed part of the periphery of the material O further diffuses to the periphery of the preformed multiple glass plate substrate O, thereby eliminating the deformed part, which in turn facilitates the molding of the preformed multiple glass plate substrate O peripheral part. When there are wrinkles in the peripheral part of the preformed multiple glass plate substrates O, the atmospheric pressure exerts a pressure directed to the second molding die 11 on the preformed multiple glass plate substrates O, so that the preformed multiple glass plate substrates can be simultaneously The wrinkles in the peripheral part of O are spread toward the periphery, thereby eliminating wrinkles.
