Problems solved by technology
However, since the curved cover plate is not a complete planar structure, during the extrusion process, the extrusion force on the planar area and the arc area of the curved cover plate is uneven, which easily leads to the gap between the diaphragm and the curved cover plate. The curved area does not fit tightly, and there are problems with air bubbles and wrinkles

Abstract
The invention provides laminating equipment and a laminating method which are used for laminating a curved surface cover plate and a functional diaphragm. The laminating equipment comprises a first mold and a second mold. The first mold is provided with a groove, the shape of the groove is matched with that of the curved surface cover plate, and the groove is configured to be used for containing the curved surface cover plate. The second mold is provided with a profiling cushion mold and a movable cushion block. the profiling cushion mold is configured to be used for placing a functional membrane; the profiling cushion mold is further configured to occupy the groove after the first mold and the second mold are closed and extrude the curved surface cover plate and the functional membrane; and the movable cushion block is arranged in the profiling cushion mold, and the movable cushion block is configured to be capable of moving in the direction close to the first mold after the profiling cushion mold occupies the groove and exerting acting force on the profiling cushion mold to extrude an arc-shaped area of the curved surface cover plate and the functional membrane. By means of the mode, the probability that bubbles and wrinkles appear in the arc-shaped area after the curved surface cover plate and the functional membrane are attached can be reduced.
Description
technical field [0001] The present application relates to the technical field of laminating molds, in particular to a laminating equipment and a laminating method. Background technique [0002] At present, the lamination of most curved cover plates and diaphragms is only to place the curved cover plates and diaphragms on two molds respectively, and then close the molds to squeeze the curved cover plates and diaphragms, so that the curved cover plates and diaphragms fit together. However, since the curved cover plate is not a complete planar structure, during the extrusion process, the extrusion force on the planar area and the arc area of the curved cover plate is uneven, which easily leads to the gap between the diaphragm and the curved cover plate. The curved area does not fit tightly, and there are problems with air bubbles and wrinkles. Contents of the invention [0003] On the one hand, the embodiment of the present application provides a bonding device for bondin...
