As shown in fig. 4-8, the attaching apparatus of this embodiment includes the aforementioned curved surface attaching device, a lower air chamber 200, an upper air chamber 400, and a flexible cushion 300, an upper opening of the lower air chamber 200 and a lower opening of the upper air chamber 400 are oppositely disposed to form an accommodating cavity, the flexible cushion 300 is located between the lower air chamber 200 and the upper air chamber 400, the accommodating cavity is divided into a lower accommodating cavity and an upper accommodating cavity, the curved surface attaching device is placed in the lower accommodating cavity, the lower air chamber 200 is provided with a first air suction opening, and the upper air chamber 400 is provided with a second air suction opening.

It can be understood that, in the actual laminating process, when the curved surface laminating apparatus of the present invention is used for laminating, as shown in fig. 4, when the lower air chamber 200 and the upper air chamber 400 are simultaneously evacuated, the position of the flexible pad 300 is not changed and does not contact with the curved surface product 100 and the curved surface laminating apparatus because the air pressures of the upper air chamber 400 and the lower air chamber 200 are almost the same. The upper air chamber 400 and the lower air chamber 200 are simultaneously vacuumized to ensure that the curved surface product can be in a vacuum cavity when being attached. As shown in fig. 5, after the vacuum-pumping process is finished, the lower air chamber 200 continues to maintain vacuum, and the upper air chamber 400 is inflated, which causes a pressure difference between the upper air chamber 400 and the lower air chamber 200, so that the flexible pad 300 is pressed down and tightly attached to the curved product 100 and the surface of the curved attaching device by the pressure difference between the upper air chamber 400 and the lower air chamber 200.

When the flexible pad 300 is pressed down to closely adhere to the curved surface product 100 and the surface of the enclosure frame jig 1, the point where the force is the largest in the adhering process is point a shown in fig. 6. That is, the area extruded by the excessive pressure is located on the edge of the frame jig 1, and the peripheral edge area of the curved surface product 100 is tightly attached to the surface of the product along the curved surface due to the flexible pad 300, so that the edge of the curved surface product 100 is uniformly stressed. That is, in the attaching process, since the edge of the attached curved product 100 is not pressed by an excessive pressure, defects such as device wrinkles and film release are not generated. In addition, as shown in fig. 7-8, when the upper surface of the curved product 100 is slightly lower than the first curved surface 12 of the enclosure jig 1, the edge of the curved product 100 is not pressed by too much pressure, and at the same time, the edge of the glass bonded by the curved surface is not pressed by too much pressure, so that the situation that the glass is broken due to too much deformation of the glass is not generated.

In conclusion, the curved surface equipment of the embodiment can better ensure the quality of the curved surface product 100 after being attached, ensure the quality of the glass of the curved surface product 100 after being attached, and realize the high yield of the curved surface product 100.

In some embodiments, the flexible pad 300 is a separate component; in other embodiments, the flexible mat 300 is already connected to the lower opening of the upper air chamber 400, and preferably, a ring of sealing rubber strips may be further provided at the edge of the flexible mat 300 to enhance the sealing effect between the upper air chamber 400 and the lower air chamber 200 when the curved product is attached.

In some embodiments, a heating assembly (not shown) is disposed within the lower plenum 200 for heating the curved product 100 within the lower plenum 200 to optimize the conforming effect of the adhesive layer.

During the attaching process, the air pressure difference between the upper air chamber 400 and the lower air chamber 200 makes the flexible pad 300 closely attached to the upper surface of the curved product 100 and the first curved surface 12 of the frame jig 1. Therefore, the curved surface laminating with the upper jig copying the curved surface product 100 is not needed, the positioning and moving relation between the upper jig and the surrounding frame jig 1 is not needed to be considered, the production cost is reduced, and the production efficiency is improved.

It should be noted that in some embodiments, the peripheral edge of the upper surface of the curved product 100 may be slightly lower than the inner edge of the first curved surface 12, which reduces the requirement for the dimensional accuracy of the structure of the curved surface engaging device. Referring to fig. 7-8, the laminating device of the curved surface product of the present invention can also realize the laminating of the curved surface product 100, and although the marginal small part area of the curved surface product 100 can not be directly pressed by the flexible pad 300, the downward pressure of the flexible pad 300 can be dispersed on the curved surface product 100, so as to drive the marginal small part area laminating.
